6b0b92674a refactor: remove dead descriptor-driven mechanisms (no remaining consumer)
Drop code whose only consumer was a retired runtime: hostBehaviors readers for
agentFileExtension, localTargetIsProjectRoot, sharedHooksDirName,
skillsManifestPrefix and skipCodexSkillsManifest; the empty
NON_REGISTRY_CONFIG_HOME_DESCRIPTORS array and live-config-guard plumbing; the
empty RUNTIME_NOTE_AUDIENCE_BY_HEADING filter; the unused resolveVersionFrom
export; and the WINDSURF_SESSION_ID workstream session key. Delete tests that
only exercised those mechanisms.

6cfa0c55d2 refactor: drop 12 runtimes, keep Claude, Codex, OpenCode, Cursor, ZCode, Antigravity
Removes kilo, kimi, kimi-code, copilot, windsurf, augment, trae, qwen, hermes,
cline, codebuddy and pi end to end: capability descriptors, installer branches
and converters (bin/install.js 14.9k -> 11.2k lines), TypeScript converters,
hook surfaces and runtime homes, review lanes qwen/kimi-code, the two pi
migrations, Kimi payload normalization in the hook guards, dead hostBehaviors
vocabulary, launcher home probes, fixtures, runtime-specific tests and the
prose that presented them as supported.

Installer output for the six kept runtimes is byte-identical to before the
prune. The Kimi tool-vocabulary tests in workflow-guard, read-guard and
read-injection-scanner are left in place pending a decision.

The fork lives on the golem15 Gitea forge, not GitHub. Package identity now
parses either host and derives in-place raw URLs for Gitea; the identity-drift
lint accepts the new host; README drops GitHub-only badges and the npm
quickstart in favour of the checkout installer.

a9a7a328e6 refactor: hard-fork GSD -> MSD (Make Software Done)
Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD
across contents and paths, upstream package/repo coordinates -> @golem15/msd-core
and golem15com/msd-core. Deep links into upstream history, sibling upstream
packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is.

Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line,
package/plugin identity, regenerated lockfile, install-tree fixtures, derived
registries and benchmark baseline; migration checksum baseline re-locked
(MSD keeps its own install state, so no install had applied the old sums);
sort-order and regex-escaped expectations in tests adjusted.

* enhance(#4570): allow disabling planner stall detection

* docs(#4570): add changelog fragment

Emitted-Drift-Ack-Growth: plan-phase.md — the explicit opt-out gate covers all five planner and checker spawn classes
Emitted-Drift-Ack-Growth: settings-advanced.md — the toggle prompt and bounded-recovery warning expose the new setting

* chore(#4570): refresh compact-content baseline

* fix(#4570): preserve default-on watchdog fallback

* docs(#4570): qualify the chunked-mode orchestrator rules with the toggle

The two chunked-planning-mode stall-watch imperatives read as
unconditional, with the opt-out stated only in a following bullet. State
the PLANNER_STALL_DETECTION_ENABLED condition inline, matching the three
sites already qualified in plan-phase.md.

* chore(#4570): refresh compact-content baselines against rebased next

* fix(#4570): sync planner stall launcher

Keep the stall-detection helper aligned with the canonical runtime launcher.

* chore(#4570): refresh compact baseline after rebase

17bf25a3d2 docs(#4671): lock the config-resolution and CLI-encoding design — Phase 0 of #4633 (#4829)
* docs(#4671): lock the config-resolution and CLI-encoding design

Amend ADR-1411 in place with the design contract for epic #4633: one
per-key resolution owner that returns the producing layer, two declared
configuration families with no precedence invented between them, one
parser and one encoder at the config-get boundary, a round-trip property
scoped to what raw output can actually carry, and the migration census,
child boundaries and anti-divergence guard spec.

Every claim about current behaviour was reproduced on next at c9a5cc3e1
in a hermetic fixture. Two corrections to the epic's framing: #4382 is
not a separate double-encoding defect (a present array already emits a
real JSON array — its own repro uses --default, the same defect as
#4262), and --default is already correct under --raw, so the disagreement
is confined to the JSON arm.

Docs-only. No runtime code, configuration behaviour or generated
artifact changes; every absorbed symptom stays live until the code
children land.

Closes #4671

* docs(#4671): close the migration-census gap and rule Decision 4

Review found the Decision-5 census missing model-resolver.cts's
projectExplicitlySetsOmit() (a workstream->root precedence walk, same
class as the six listed Family A implementations) and flagged init.cts's
readConfigJsonBoolean/readConfigJsonValue as a plausible second gap
(single-layer reads, same class as the listed single-layer readers).
Verified init.cts directly: confirmed real, added.

Decision 4 asked for an explicit maintainer ruling on raw-mode losslessness.
Ruled: freeze --raw as documented (display/shell-interpolation contract,
lossy for non-scalars). A lossless --raw stays out of scope, its own
future issue.

* docs(#4671): qualify config resolution guarantees

Distinguish correct classification from precedence guarantees and freeze raw as lossy output.

76ef60ba25 enhance(#4836): prefer the graphify CLI for planner and researcher graph queries (#4874)
* enhance(#4836): prefer the graphify CLI for planner and researcher graph queries

The planner gets one knowledge-graph query per phase and the researcher two
or three, and that single shot decides which modules the plan treats as
related — and therefore how tasks are ordered into waves. It was spent on
the built-in reader, which seeds by case-insensitive substring match over a
node's label and description and then expands a hardcoded two hops. The
phase "User Authentication" seeds on `author`, `authoring` and
`unauthorized` with the same weight as `authenticate`, and when the
inflated payload exceeds `--budget` the trimmer drops edges by confidence
tier — so the highest-confidence tier can be discarded to fit a payload
that bad seeding inflated in the first place.

The graphify CLI is already a hard dependency of /gsd-graphify build, and
it ranks seeds (IDF weighting, trigram fuzzy matching) and applies context
filters before traversal. Both prompts now prefer it and fall back to the
built-in reader, branching on `command -v graphify` — the same degradation
shape the repo already uses for Context7 to ctx7. Binary presence is a
self-satisfying gate: a graph can only exist if the binary built it, so the
fallback covers edge cases (a CI checkout with a committed graph, a binary
since removed), not the common path. No new config key and no new tool
grant — both agents already have Bash.

The planner additionally runs `graphify affected`. The reference states its
own goal as "which subsystems may be affected by changes in this phase",
which is literally reverse traversal by relation; the built-in reader only
approximates it with undirected two-hop expansion and has no equivalent
verb, so `affected` is skipped on the fallback path.

`graphify status` now reports `graph_path`, the resolved absolute graph
location, on both the present and the missing branch. The CLI takes the
graph location as `--graph`, and the prompts must not re-derive
`.planning/graphs/graph.json` for it: that would point the CLI at a
non-existent local mirror in exactly the umbrella multi-repo setup
`graphify.graph_path` (#1825) exists to serve. For the same reason the
presence gate in both prompts is now the `status` call itself rather than a
bare `ls` of the default location, which was already blind to the override.

Known limit, stated in both prompts rather than implied: the two paths
return different shapes. `graphify query` emits prose and has no `--json`
flag; the built-in emits JSON with per-edge confidence tiers and
budget_met/budget_estimate. `--budget` also counts rendered output on one
and estimated payload bytes on the other (#2738) — same flag name,
different unit. Both are read by a model and nothing machine-parses the
injected block. With graphify absent from PATH the injected context is
byte-identical to before.

Closes #4836

Emitted-Drift-Ack-Growth: gsd-phase-researcher.md — the CLI-first branch, the reason it is preferred, and the output-shape warning are the deliverable; a pointer to a part would not be read at the decision point.
Emitted-Drift-Ack-Growth: gsd-planner.md — one sentence in the load_graph_context step pointer, so it stops naming the default graph path the reference no longer assumes.

* docs(#4836): record the CLI-first graph query in the planner and researcher entries

* chore(#4836): add changeset fragment

* enhance(#4836): name the full domain word in the planner's query-term examples

The reference's own example — phase "User Authentication" → term "auth" — is
the exact collision the CLI-first path exists to avoid, and it stays a
collision whenever the fallback path runs, since that path matches the term as
a substring of label and description.

* fix(#4836): surface graph_path on the unparseable-graph status branch

graphifyStatus() returned graph_path on the exists:true and exists:false
outcomes but not on the third, error, outcome (graph.json present but
unparseable). The planner/researcher prompts gate CLI-first dispatch on
exists, not on this outcome, so a corrupt graph file made them fall
through to the CLI-first branch with the literal <graph> placeholder and
no real path to substitute.

* docs(#4836): note graph_path's trust boundary at the --graph interpolation

graph_path is reflected verbatim into a double-quoted --graph argument the
agent executes via Bash. It comes from graphify.graph_path, a config
surface already trusted elsewhere, so this isn't a new trust boundary --
but it is a new injection site (no --graph flag existed on this call
before). One-line caution for anyone hardening this later.

55fba5f7ce feat(#4917): add the PlanningDoc parse → mutate → serialize seam — Phase 1 of #4906 (#4918)
* feat(#4917): add the PlanningDoc parse -> mutate -> serialize seam

Phase 1 of epic #4906, implementing ADR-4910 and its 2026-09-21 amendment. Net-new
leaf module; NO call site is migrated, so nothing in the twelve absorbed issues
changes behavior yet.

src/planning-document.cts composes the seams that already exist rather than
reimplementing them: markdown-sectionizer for structure (fences and code spans
come from stripFencedCode / scanInlineCodeSpans, never a second scanner),
markdown-table for tables, frontmatter for frontmatter, write-set for Result<T>.

What is structural rather than conventional:

- A field node carries labelSpan, valueSpan and trailingSpan separately, and the
  only write entry point takes a node id and writes into valueSpan. trailingSpan
  is readable and has no exported writer, so the #2853/#3584/#4852 rule ("the verb
  owns the count token ONLY") stops depending on an author remembering a third
  capture group.
- Mutation is node-addressed. A handle is minted by the parser, so a caller cannot
  name a node the parser did not find. No path strings — a path is a grammar, and a
  grammar needs a parser.
- serialize splices staged spans into the ORIGINAL buffer. A no-edit serialize is
  byte-identical, which is what eliminates the #4499 defect without a targeted fix, and which also
  makes an already-escaped table cell impossible to double-escape on a round trip.
- A node that fails to parse carries its own error and span; siblings stay readable.
- Per the ADR amendment, serialize REFUSES whenever any node carries a parse error,
  even with zero staged edits, naming the offender.

One defect was found while building and fixed in place rather than deferred:
PLANNING_ARTIFACTS first derived from isCanonicalPlanningFile unfiltered, so
config.json, state.json, milestone.lock and skill-manifest.json were accepted and
returned {ok:true, nodes:[]} — "this document records nothing" when the truth was
"I have no grammar for this file". That is the exact empty-vs-error confusion this
epic exists to remove (#4899, #4900), reproduced inside the seam built to prevent
it. The registry now filters to .md while still DERIVING from
isCanonicalPlanningFile, because hand-writing a second list is the divergence this
epic is about, and parsePlanningDoc refuses a non-markdown kind at the document
level per ADR-4910 section 5.

New bin/lib module bookkeeping: .gitignore, eslint.config.mjs ignore (ADR-457 —
lint the .cts, not the emitted .cjs), docs/INVENTORY.md row, regenerated
docs/INVENTORY-MANIFEST.json, and the CONTEXT.md glossary entry.

* test(#4917): cover the PlanningDoc seam across 28 input classes

30 cases in 14 describe blocks, one per row of the phase test matrix.

The two load-bearing tests are the fast-check properties (seed 20260921,
numRuns 200):

- a single node mutation leaves every byte outside that node's valueSpan
  identical to the source
- serialize with zero staged edits is the identity function

Both are DOCUMENT-SHAPED per CONTRIBUTING.md fixture provenance (#2371): the
generator assembles arbitrary frontmatter, heading, label and value text with
join(), and never calls serialize or any other function from the module under
test to build a fixture. Seeding the generator from the module's own writer
would make the document shape a constant, and the property could then never
explore a document the writer would not itself emit.

Verified the byte-range assertion is not vacuous with a control run: it passes
against the real writer and FAILS against a simulated #4852 writer (one capture
group, replace-to-end-of-line), which visibly drops the trailing annotation.

Boundary coverage is zero / one / two staged edits. Negative space carries its
own rows — bold emphasis in prose, a field-shaped line inside a fenced block,
the same inside an inline code span, and a horizontal rule mid-body all
correctly mint no node. Row 24 is the Generative-Fix-Divergence parity
assertion: PLANNING_ARTIFACTS must not diverge from isCanonicalPlanningFile.
Row 28 covers the non-markdown canonical file found during the build.

Assertions are structural throughout — a typed Result / NodeRead /
SerializeOutcome shape, or a byte range computed from the node's own Span.
Full-string equality appears only where the contract IS byte equality.

* fix(#4917): apply review findings — refuse unrepresentable values, compose the layers the seam claimed

Three review passes ran against this branch: /security-review, an isolated
adversarial pass, and a standards+spec pass. Five findings, all fixed here. Every
one is the epic's own failure class reproduced inside the seam built to end it,
which is the thing worth noticing.

1. setFieldValue accepted a value containing a newline. It survived serialization
   and reparsed as a REAL sibling field — one write to Plans forged a second
   Owner into a document that already had one. Content became structure, which
   defeats ADR-4910 Decision 2's "cannot reach past its own token by
   construction": the token boundary is a LINE boundary.

2. setFieldValue accepted a value containing the trailing separator and SILENTLY
   TRUNCATED it. Staged "sneaky - annotation", read back "sneaky", with the
   remainder reclassified as trailing prose. No error, nothing unreadable, both
   resulting nodes parsing perfectly. Worse than (1) because it loses the
   caller's own value rather than adding something visible.

   Both are fixed by ONE general check, deliberately not a blacklist:
   setFieldValue rebuilds the candidate line, re-parses it through the same field
   grammar, and refuses unless the value reads back identical. Blacklisting the
   separator would close this instance and leave the class open for whatever
   separator the grammar grows next. The round-trip check is ADR-4910 Decision 4
   stated executably.

3. The module reimplemented two layers it claims to compose. Checklist detection
   hand-rolled a checkbox regex that markdown-sectionizer's iterateBullets
   already owns. Frontmatter span detection re-derived fence handling because
   frontmatter.cts's frontmatterRegion was module-private — so ADR-4910 section 1's
   stated layering was UNREACHABLE as written, and the first implementation
   routed around it silently instead of surfacing the gap.

   frontmatterRegion is now exported (additive only; ADR-2143 section 2's
   extend-never-mutate lock is inherited) and both layers are consumed.

4. The CONTEXT.md glossary entry asserted "the Frontmatter Module supplies
   frontmatter" while zero frontmatter.cts code was invoked. That was a false
   claim in the repo's vocabulary of record, written by me, and it is now true
   rather than edited away.

5. Adopting iterateBullets narrowed GFM coverage: it classifies only
   dash-prefixed task items as checkboxes, so "* [ ] x" and "+ [x] y" stopped
   becoming checklist nodes. Widening the sectionizer is forbidden by the
   inherited lock, so the task-list MARKER is interpreted in this module while
   bullet STRUCTURE still comes from the sectionizer.

The sharpest finding was not a defect. The fast-check generator constrained
values to [A-Za-z0-9 .,!?], so it could not emit an em-dash, newline, backtick,
pipe or asterisk — precisely where (1) and (2) lived. The property was real,
seeded and non-vacuous, and structurally blind to the module's actual bug class.
The generator now spans the grammar's own metacharacters, and a new property
asserts that every value setFieldValue ACCEPTS round-trips identically. Proven
able to fail: against a scratch copy with the guard stripped it fails after 7
cases on newValue "\n".

Recorded as a measured boundary, not fixed: a bare CR inside a field line leaves
that field unrecognised. Measured — sibling fields still parse, no error node,
and serialize stays byte-identical, so the worst case is an unreadable field and
never a damaged document. Flagged for Phase 4's empty-vs-error census.

b956bb7c67 fix(#4834): gate the launcher PATH arm on runtime identity and prefer config-home installs (#4902)
* test(#4834): failing-first launcher hijack regressions

* fix(#4834): gate the launcher PATH arm on runtime identity and prefer config-home installs

A gsd_run on PATH that cannot prove it is @opengsd/gsd-core (a foreign package, or a
release older than the runtime-identity verb) is no longer accepted by the launcher
snippet's PATH arm; resolution falls through to the hard error when no path-based
candidate matches. The runtime-config-home arm now precedes the PATH arm, restoring
the documented prefer-local-over-PATH order, so an installer-managed install wins
even against a genuine global. The 16-home probe list is factored into _gsd_homes()
and the identity gate into _gsd_id_ok(), keeping the per-copy delta at +141 bytes.

The files whose frozen ceilings had no headroom (gsd-executor, gsd-plan-checker,
gsd-verifier, gsd-planner, execute-phase, execute-plan) now load the resolver by
@-include from gsd-core/references/gsd-run-resolver.md (the onboard.md pattern)
instead of carrying an inline copy. Propagated to all other inlined workflow/agent
copies via scripts/sync-runtime-launcher.cjs; the resolver reference re-copied
byte-equal (parity B2); the hard-error text, docs/how-to/diagnose-a-foreign-gsd-tools.md,
and the CONTEXT.md launcher predicate updated to match (#4834); the quick-batch row-48
guard gains the canonical-preamble sweep carve-out (#4834, per its own #3730/#2529
precedents); the compact-content benchmark baseline regenerated.

eea9247c93 enhance(#4095): checkpoint:decision auto-selection is opt-in via auto_select (#4912)
* enhance(#4095): checkpoint:decision auto-selection is opt-in via auto_select

Auto-mode used to auto-select a checkpoint:decision's first <option>
unconditionally, making a decision checkpoint's safety depend on option
presentation order rather than an authored choice. Add an optional
auto_select="<option-id>" attribute on the <task> tag: absent, auto-mode
now escalates to a human exactly like gate="blocking-human" does; present,
it names the option auto-mode selects; naming an id with no matching
<option id> is a hard structural-validation error at plan-parse time
rather than a silent fallback to the first option. gate="blocking-human"
continues to win over everything, unchanged.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

* fix(#4095): anchor auto_select/id attribute regexes past hyphenated decoys

An isolated adversarial review of the auto_select work found that both new
attribute regexes used \b as their left anchor, which is a word boundary,
not a "start of attribute name" boundary. A decoy attribute ending in the
same word (e.g. data-id="...") sitting before the real id="..." on the
same <option> tag matched first, silently corrupting the extracted option
id. Anchor on (?:^|\s) instead so only the real attribute name can match.
Adds a regression test reproducing the exact decoy-attribute shape, plus a
Unicode option-id test from the same review pass.

* test(#4095): register auto-select-attribute.test.cjs in the docs-guard lane

lint-docs-guard-registration failed: the new test reads docs/reference/
plan-md.md but was not registered, so a future edit to that doc could
silently desync from the test without the guard catching it on the PR
that changed the doc. Registered alongside its direct precedents
(precondition-element.test.cjs, reversibility-tagging.test.cjs), which
read the same file for the same reason.

* fix(#4095): fit the decision bullet under execute-phase.md's frozen byte ceiling

The remote gsd-test run caught what local checks missed: execute-phase.md
carries a frozen ADR-857 Phase-6 byte ceiling (93600) with only 36 bytes
of headroom before this change, and the original checkpoint:decision
wording pushed it to 93772 (over the ceiling). Cascaded into failures in
phase6-capstone-conformance, execute-phase-completion-reconciliation,
claude-orchestration, and the compact-content drift-report test.

Also caught: tests/package-legitimacy-gate.test.cjs anchors a
"decision is conditional, not unconditional" safety check on the literal
phrase "first option" in the decision bullet — which #4095 deliberately
removes, since there is no more unconditional first-option pick. The test
was asserting an assumption this change intentionally makes obsolete;
re-anchored on tokens that still identify the bullet ('decision',
'auto-spawn') without weakening what the test actually verifies (the
bullet must still carry a blocking-human carve-out).

Also fixed a word-order mismatch between my own new test's regex and the
actual doc text it was asserting against (tests/auto-select-attribute.test.cjs).

Regenerated the compact-content benchmark baseline
(tests/fixtures/compact-content-benchmark-baseline.json) to match the new
byte counts.

Emitted-Drift-Ack-Growth: gsd-executor.md — +7 bytes (49138 -> 49145), from the auto_select carve-out added to the checkpoint:decision auto-mode bullet; already trimmed once to fit the 49152 hard cap.
Emitted-Drift-Ack-Growth: execute-phase.md — +12 bytes (93564 -> 93576), from the same carve-out in the orchestrator's decision bullet; kept 24 bytes under the frozen 93600 ADR-857 ceiling after two rounds of trimming for clarity vs. margin.

5e729445d3 fix(#4657): give the ui consideration probe a text_en language channel (#4804)
* test(#4657): add failing-first coverage for the ui probe's text_en channel

Mirrors the #3717/#4156 test shape onto the UI adapter: a failing-first
proposeConsiderations regression (Danish text + English text_en must classify
as its English equivalent, not land in the #1110 unclassified sentinel),
proposeElements/analyzeCoverage/CLI end-to-end pairs, fail-closed text_en
validation cases (empty/whitespace/non-string, unconditional under an
elements override), a ui-phase.md Step 9.5 workflow-prose contract test, a
reference-doc Inputs parity test, and a fast-check property proving any
cue-matching prose classifies identically under a cue-free Danish rendering
plus text_en. All new assertions are RED until src/ui-consideration-probe.cts
and the workflow/reference docs are updated.

* fix(#4657): give the ui consideration probe a text_en language channel

Element gains an optional text_en; classifyElement's own signature stays
untouched (a locked, directly-tested export) and the text_en ?? text
selection is pushed to the two classification call sites (proposeConsiderations,
proposeElements) instead. text_en is validated fail-closed: an empty or
whitespace-only value throws rather than silently winning the ?? fallback and
degrading classification to zero kinds.

Mirrors #3717/#4156 onto the UI adapter: ui-phase.md Step 9.5 gains the
Non-English projects section (mirroring spec-phase Step 5.5) and the
ELEMENTS_JSON shape comment documents the field with both zero-applicable
guard arms named; the reference doc's Inputs section, the PROBE.ui CONTEXT
predicate (with both derived indexes regenerated), and the nav-override
test expectation stay in sync. The ui-phase contract test carries the
site-scoped allow-test-rule marker and its cluster is registered in the
test-file-count allowlist ratchet.

003d982c83 fix(#4623): keep repo-wide planning docs out of the verification digest, and accept --files on verification.fingerprint (#4749)
* fix(#4623): keep repo-wide planning docs out of the verification digest, and accept --files on verification.fingerprint

Two defects in the covered-input fingerprint (#4155), one issue.

1. `computeCoveredDigest` hashed the whole bytes of every declared path
   uniformly, so `.planning/ROADMAP.md` and `.planning/REQUIREMENTS.md` —
   which every phase rewrites as ordinary bookkeeping, and which the closing
   phase's own `phase.complete` / `requirements mark-complete` rewrite AFTER
   the verifier ran — flipped every phase that declared them to `stale` on
   zero implementation change, and from there `isPhaseComplete` →
   `init.manager` → `complete-milestone`'s `ALL_PHASES_VERIFIED` gate.
   Fingerprint v2 leaves any direct child of a planning root out of the
   hash: `.planning/` itself, plus the phase's own planning root (the parent
   of its `phases/`, so `planningDir`'s `<project>/` and `workstreams/<ws>/`
   layouts are covered without the digest knowing what a workstream is —
   `sharedPlanningRoots` / `isSharedPlanningDoc`, defined by position rather
   than a name list so the set cannot drift; a root is accepted only when the
   phase dir sits under a `phases/` directory inside `.planning/`). Such a path is still validated
   exactly as every other covered path (confined, present, a regular file —
   the fail-closed contract is unchanged); only its bytes are ignored, and a
   declaration made only of shared documents fails closed like an empty one.
   A stored digest names its version, and `readVerificationStatus` now
   recomputes under THAT version (`parseFingerprintVersion`,
   `KNOWN_FINGERPRINT_VERSIONS`): a legacy v1 report keeps v1 semantics
   until it is re-fingerprinted, so the upgrade alone stales nothing; a
   version this build cannot recompute fails closed.

2. `verification.fingerprint` received a raw positional slice, so
   `--files a`, `--files "a,b"` and `--files a --files b` all put the literal
   token into the covered set and failed closed as "a covered file is
   missing, unreadable, or escapes the project root" — the message that
   convinced the reporting project the digest was permanently
   unrecomputable. `parseFingerprintFileArgs` accepts every form (plus
   `--files=a,b`, freely mixed with bare positionals), treats any other
   `--flag` and an empty `--files` value as usage errors that say so, and
   the phase-dir argument must now be an existing directory: omitting it
   used to take the first covered file as the phase dir and print a
   plausible digest over the rest at exit 0.

Regression tests (tests/verification-status.test.cjs, #4623 block): the
cross-phase case from the report, the same-phase `requirements
mark-complete` / `phase.complete` cases from the thread, a workstream-scoped
root, v1-preserved / unknown-version-stale, the fail-closed cases (missing,
directory, escaping symlink, all-shared), every `--files` form against the
bare form, the unknown-flag / empty-value / omitted-phase-dir errors, and
AC5's zero-file error. Verified failing against the pre-fix source: 29 of 34
fail, the 7 that pass pin behaviour the fix must leave unchanged.

Docs: CONTEXT.md Verification Module, agents/gsd-verifier.md's
covered_files instruction (rewritten in place — the file sits 21 bytes under
its LARGE hard cap), gsd-core/templates/verification-report.md.

Fixes #4623

Emitted-Drift-Ack-Growth: gsd-verifier.md — the #4155 covered_files instruction now states that planning-root docs are digest-inert (#4623); +18 bytes, under the LARGE cap

ad1477d659 enhance(#4154): validate configured entrypoints before reporting install success (#4249)
* test(260903-m7p): expose configured-entrypoint validation gap

* enhance(260903-m7p): validate configured entrypoints before success

* test(260903-m7p): require pre-success entrypoint validation

* enhance(260903-m7p): gate install success on entrypoints

* test(260903-m7p): cover configured entrypoints across runtimes

* enhance(260903-m7p): cover emitted runtime entrypoints

* fix(260903-m7p): sandbox HOME in finishInstall test and fix changeset pr number

- finishInstall(...'cline'...) calls writeNonClaudeDefaults(runtime) in-process
  before the new configured-entrypoint assertion throws. Without a HOME +
  config-location-env sandbox that write resolved through the ambient
  environment and landed in the developer's live ~/.gsd (confirmed absent on
  origin/next baseline, present only on this branch — full-suite HERMETICITY
  WARNING). Sandbox HOME/USERPROFILE and scrub config-location env for the
  duration of the test, matching the existing in-process finishInstall/
  install() pattern in tests/install.test.cjs (#2665).
- .changeset/quick-wasps-sing.md: pr: 0 is a never-backfilled placeholder
  (CONTRIBUTING.md) that fails changeset-lint's invalid_pr check; set to the
  fork PR number until the upstream PR number is known.

* fix(260903-m7p): repair cross-platform and pre-existing shape fallout

- tests/configured-entrypoint-validation.test.cjs: the win32 branch of
  ensureCodexHooksJsonSessionStart writes a .cmd shim under
  <codexRoot>/hooks/; create that dir in the test (the real installer only
  calls this once hooks/gsd-check-update.js already exists) and assert the
  platform-common entrypoint shape instead of a fixed non-Windows array,
  since win32 legitimately emits two entries (cmd shim + script).
- tests/install.test.cjs: finishInstall's shared settings-json return now
  carries configuredEntrypoints/rollbackInstallerMigrations for every
  runtime on that path (trae included, not just Claude/Cursor/Windsurf);
  update the trae install() exact-shape assertion to match.

* fix(260903-m7p): keep .sh interpreter tracking consistent with unresolved bash

configuredEntrypointsForHook's shell branch dropped interpreterCandidates
entirely when resolveBashExecutable returned null, unlike the sibling
portableHooks runner entry a few lines below (which correctly falls back to
the literal 'bash' token). Found via agy adversarial review; verified
unreachable through the current call graph (buildHookCommand's own
resolveBashRunner==null gate already short-circuits before
recordConfiguredHookCommand runs), so this is a defensive consistency fix,
not a live-bug patch — kept for the next caller that does not share that
gate.

* chore(260903-m7p): backfill changeset pr number to the opened upstream PR

.changeset/quick-wasps-sing.md carried the fork PR number (16) as a
placeholder until the upstream PR existed; open-gsd/gsd-core#4249 is now
open, so record its real number per CONTRIBUTING.md's changeset pr-field
convention.

* fix(#4154): track already-registered hooks for entrypoint validation on update

applySettingsJsonHooks registers each guard hook only if absent, so a hook
already present from a prior install keeps its stale on-disk command. The
new entrypoint tracker always records the freshly-computed command for it,
which never matches what is actually persisted, so the exact-string filter
in finishInstall silently dropped it from validation — the Blocker case
this feature exists to catch (an already-installed entrypoint going stale
between installs) was exactly the case it never validated.

Match on the managed script's basename instead, which the persisted
command carries either way, so an already-registered hook stays in the
validated set. Regression test forces this path by mutating a
freshly-installed hook's persisted command before a second install.

* fix(#4154): distinguish an unreadable script from a missing one

validateConfiguredEntrypoints folded an EACCES statSync failure into the
same 'missing' reason as ENOENT, misreporting a real permission problem as
an absent file. Check the error code and report 'unreadable' instead.

* docs(#4154): document entrypoint validation's rollback and PATH scope

CONTEXT.md's Runtime Hooks Surface Module / Installer Module entries had
no mention of ConfiguredEntrypoint/validateConfiguredEntrypoints, despite
bin/install.js x CONTEXT.md being this repo's strongest co-change pairing.

The update-gsd.md how-to overstated what a validation failure undoes: for
Codex/Cursor/Windsurf/Kimi, their own writer already persisted hooks.json/
config.toml inside install() before the aggregate validation call runs, so
there is no rollback path for that write regardless of "where available"
phrasing. Also note that interpreter resolution checks the installer's own
PATH, not necessarily the PATH a hook fires under later (#2979 launchers).

* chore(#4154): point changeset pr field at the fork PR while CI runs there

Mirrors the branch's own prior backfill commit: pr: matches whichever PR
number changeset-lint is currently validating against (fork PR #16 during
the fork-first CI/review loop), flipped back to the upstream PR number
right before the final push to open-gsd/gsd-core.

* fix(#4249): address adversarial-review findings in entrypoint validation

An internal adversarial review (agy/gemini-3.8-flash-high) of the whole PR
found several real gaps beyond the human reviewer's Blocker, verified
against source before fixing:

- Codex's install() result bound rollbackInstallerMigrations to the narrow
  installer-migrations-only rollback instead of restoreCodexSnapshot (#3245),
  the full pre-install snapshot/restore Codex already owns for exactly this
  case — a validation failure discovered outside install() reverted nothing
  of the config.toml/hooks.json that call had already written.
- The register-only-if-absent basename match from the prior fix used a bare
  substring, which an unrelated user command mentioning the same filename
  could false-positive into GSD's validated set — anchored on the
  `/hooks/<basename>` path segment instead.
- nodeCandidates checked raw process.execPath (always true — we're running
  in that process) instead of normalizeNodePath's stable version-manager
  alias, the same one buildNodeRunnerChainToken bakes as its first choice —
  a false green regardless of whether that alias itself still resolves.
- An entry with no interpreterCandidates (Cline's PreToolUse hook, or a
  Windows-Claude .sh hook invoked without a bash runner) runs via its own
  shebang; validateConfiguredEntrypoints checked only file-type, never the
  execute bit. Cline's writer also never reported an entrypoint at all.
- Duplicate (configPath, scriptPath) entries (e.g. Kimi's context-monitor
  hook registered across several events) were validated once per duplicate.

Each fix is covered by a new or extended test; the Codex one required
inlining runCodexInstall's env sandboxing so the rollback closure — which
re-resolves the $HOME-relative skills root live — runs before the sandbox
is torn down, matching how installAllRuntimes' real aggregate gate calls it.

* docs(#4249): document the round-2 entrypoint-validation fixes

Runtime Hooks Surface Module and Installer Module entries now name
ConfiguredEntrypoint's not-executable reason, the normalizeNodePath
alignment, Cline's tracked hook, and which install() result the
finishInstall/installAllRuntimes rollback path actually reverts per
runtime (Codex's full snapshot vs. the others' narrow migrations-only
rollback).

* chore(#4249): point changeset pr field at the upstream PR now that fork CI is green

* fix(#4249): address agy adversarial-review findings

- validateConfiguredEntrypoints: statSync alone never detects a
  chmod-000 script (it only needs parent-dir search permission), so an
  interpreter-invoked entry with an unreadable script passed validation.
  Add an explicit R_OK check for the interpreterCandidates branch only —
  the candidate-less/shebang branch already has its own X_OK gate.
- docs/how-to/update-gsd.md: the blanket "does not revert" claim was
  false for Codex, which reverts config.toml/hooks.json via its full
  pre-install snapshot; qualify it per runtime.
- tests/codex-config.test.cjs: the #4249 rollback regression test
  asserted skills/ and VERSION were reverted but never asserted
  config.toml/hooks.json were too, despite the test's own stated intent.
- CONTEXT.md: qualify which interpreterCandidates entries get
  normalizeNodePath'd (Node hooks only, not .sh/bash) and note Codex's
  Windows .cmd shim as a third candidate-less case that relies on
  extension dispatch, not a shebang.

* fix(#4249): validate Cline's PATH-dependent interpreter, not just its execute bit

Cline's hook is a hybrid: it self-executes via '#!/usr/bin/env node',
so it needs the execute bit (like any shebang-invoked entry), but its
interpreter is looked up on PATH by 'env' at hook-fire time (unlike
every other GSD JS hook, which bakes an absolute node path specifically
to avoid that dependency). The candidate-less/interpreterCandidates
fork treated these as mutually exclusive, so Cline's entry silently
skipped interpreter resolution entirely — a completely missing 'node'
on PATH would still validate successfully.

Add an orthogonal selfExecutable flag so both checks run for entries
that need them. (CodeRabbit finding on the fork rehearsal PR.)

* fix(#4249): address second-round adversarial review findings (opus + agy)

- validateConfiguredEntrypoints: R_OK now runs for every scriptOk entry,
  not just interpreterCandidates ones — a self-executable shebang script
  is still opened and read by its kernel-invoked interpreter, so X_OK
  alone never proved it was readable.
- selfExecutable is now the sole, explicit source of truth for the
  execute-bit check (every producer that needs it sets the flag) instead
  of being partly inferred from an absent interpreterCandidates, which
  Cline's hybrid entry also carries.
- The execute-bit check now skips explicitly on win32 (matching
  resolveExecutableBinary's own carve-out) instead of relying on Node's
  accessSync(X_OK)-as-F_OK no-op, which only protects a real Windows
  machine and not a test that simulates win32 on a POSIX runner.
- bin/install.js: fixed a stale comment claiming no runtime's
  install()-time writes have a rollback path — Codex's does
  (restoreCodexSnapshot) — and added the omitted Cline to both that
  comment and CONTEXT.md's equivalent lists.
- CONTEXT.md: fixed the Cline description left stale by the previous
  commit's selfExecutable addition, and rewrote the validation-mechanism
  paragraph for clarity (writing-for-agents pass).
- docs/how-to/update-gsd.md: split an overloaded 4-clause sentence.
- Removed a fault-injection integration test that could not reliably
  exercise the real installAllRuntimes -> finalize -> rollback wiring
  without fighting the installer's own pre-registration existence
  guards; the constituent pieces remain covered individually.

* fix(#4249): pin platform in X_OK-testing entries so they're deterministic cross-CI-runner

X_OK is a POSIX-only concept, skipped entirely when an entry's platform
is win32 (matching production). Two test entries omitted platform,
defaulting to process.platform — on an actual windows-latest CI runner
that silently skipped the very check they were meant to exercise,
turning 'not-executable' into a false pass. Pin platform: 'linux' so
these are deterministic regardless of which OS runs the suite.

* fix(#4249): classify EPERM the same as EACCES in statSync error handling

Windows raises EPERM (not EACCES) for a parent directory that couldn't
be traversed into — was falling through to 'missing', misreporting a
genuine permission problem as a nonexistent path.

* docs(#4249): address final CodeRabbit doc-completeness findings

- CONTEXT.md: install()'s documented result shape omitted
  configuredEntrypoints; the ConfiguredEntrypoint shape omitted
  selfExecutable.
- docs/how-to/update-gsd.md: the failure-mode sentence omitted
  unreadable and lacks-execute-permission, which the installer also
  rejects.

* fix(#4249): stop double-validating every configured entrypoint on install/update

installAllRuntimes' finalize() already runs assertConfiguredEntrypoints
once over the aggregate set; finishInstall then re-ran the identical
check per runtime in the printSummaries loop right after, so every
entrypoint paid its statSync/accessSync/interpreter-resolution cost
twice on every install and update. Add entrypointsAlreadyValidated to
skip the redundant pass specifically on that path, while leaving the
check intact for any caller that invokes finishInstall directly.

* chore(#4154): point changeset pr field at rehearsal fork PR while CI runs there

* perf(#4249): memoize interpreter candidate resolution across entrypoints

resolveExecutableBinary walked PATH once per (entry, candidate) pair; a
typical install has a dozen-plus entries sharing the same few candidate
lists (process.execPath for JS hooks, bash for shell hooks). Cache by
(platform, candidate) so each distinct pair resolves once per validation
call instead of once per entry.

* chore(#4249): point changeset pr field at the rebased rehearsal fork PR

* fix(#4249): drop entrypoint tracking from the now-dead Codex event writer

#2586 (landed on next after this branch forked) removed install.js's
CODEX_EXTENDED_HOOK_EVENTS registration loop, so ensureCodexHooksJsonEvent
no longer runs during install or update. The ConfiguredEntrypoint records
this branch added inside it were therefore unreachable and untested. Restore
the function to its upstream shape; the entrypoints it used to report were
never collected by any caller.

* refactor(#4249): drop the revalidation bypass flag and the candidate cache

Both were this PR's own micro-optimisations over a set of roughly a dozen
entries. `entrypointsAlreadyValidated` let a caller turn the finishInstall
gate off to save one statSync/accessSync pass; `resolvedCandidateCache`
memoised resolveExecutableBinary across entries that are already deduped by
(configPath, scriptPath). Neither is measurable, and the flag was the only
way to reach finishInstall with validation disabled. finishInstall now
always validates what it is given.

* chore(#4249): point the changeset pr field back at the upstream PR

* refactor(#4249): track settings.json entrypoints without the hooksSurface gate

The install-surface writer only tracked configured entrypoints when the
runtime's descriptor also declared `hooksSurface: 'settings-json'`. Nothing
asserts that axis agrees with `installSurface`, so a descriptor that broke
the coupling would silently pass `configuredEntrypoints: undefined` and drop
that runtime out of the validation this PR adds — reintroducing the exact
'reports Done! over a broken entrypoint' failure #4154 exists to close.

Remove the dependence rather than test it: everything recorded on this path
lands in settings.json by construction, and the registered-command filter
already discards entries no persisted hook references.

* chore(#4249): put the changeset body in the documented two-part format

CONTRIBUTING.md and .changeset/README.md both show
`**<bold change>** — <symptom-led explanation>.`; the fragment was a single
unbolded sentence.

* chore(#4249): point the changeset pr field at the rehearsal fork PR while CI runs there

* fix(#4249): restore the whole manifest-tracked GSD file set on Codex rollback

#3245's snapshot covers config.toml, hooks.json, skills/gsd-*, agents/gsd-*
and gsd-core/VERSION. The install overwrites every other GSD-owned file too —
hooks/, gsd-core/CHANGELOG.md, scripts/, gsd-core/.gsd-runtime, the manifest
itself — before the entrypoint-validation gate runs, so a validation failure
left the new payload sitting on top of the restored old config.

Snapshot the file set the PREVIOUS install's gsd-file-manifest.json claims,
before runInstallerMigrations so the bytes are the true pre-install state, and
restore it from both Codex rollback closures ahead of the per-surface restores.
Files only the failed install introduced are removed, read from the manifest
now on disk. The manifest is already the authoritative record of what GSD owns,
so no second hand-written list can drift out of sync, and user-owned files are
never snapshotted or removed. Every path is confined through
resolveInstallRelativePath, so a hand-edited manifest cannot turn rollback into
an arbitrary-path write.

Non-Codex runtimes are unaffected: the snapshot is gated on the same
tomlConfigInstall + non-minimal condition as #3245's.

* fix(#4249): keep the managed-file snapshot honest in minimal mode and on a bad manifest

Two follow-on defects in the previous commit's snapshot:

- The capture was gated on `!isMinimalMode`, copied from #3245. A core/
  --minimal Codex install still writes gsd-core/, hooks/, scripts/ and the
  manifest, and restoreCodexSnapshot is reachable in that mode (#2695), so the
  snapshot came back empty while the rollback still ran — and its removal pass
  would have deleted every file the new manifest lists. Gate on
  tomlConfigInstall alone, matching where the rollback actually reaches.

- An unreadable or unparseable prior manifest was caught alongside ENOENT and
  treated as a fresh install. That is the same empty-snapshot state, so a failed
  update over a real install with a corrupt manifest could delete its prior
  payload. Track whether the pre-install GSD-owned set is KNOWN: ENOENT means
  known-empty; any other read error or a parse failure means unknown, and the
  restore closure returns without touching anything, degrading to #3245's
  narrower rollback. Deliberately not fatal — a corrupt manifest has to stay
  repairable by reinstalling over it.

Both paths are covered by red-checked regression tests.

* fix(#4249): snapshot Codex skills, agents and VERSION in minimal mode too

commit removed from the manifest snapshot. restoreCodexSnapshot is reachable
for a core/--minimal install (#2695), and its pass-2 sweeps remove every gsd-*
skill dir and gsd-* agent file the snapshot does not claim — so with an empty
minimal-mode snapshot a rollback deleted the whole skills/agents surface with
nothing to restore it from. Codex resolves skills to $HOME/.agents/skills via
the ADR-1239 skills-kind home override, so this is also the reason manifest
`skills/` keys do not resolve under configDir: that surface belongs to this
snapshot, not to the manifest-driven one.

Gate on tomlConfigInstall alone. _codexPreConfigRollback stays null in minimal
mode — doing nothing on an early failure is the non-destructive side.

Covered by a red-checked regression test that plants bytes in an alternate-home
skill file, reinstalls under the core profile marker, and asserts the rollback
restores it.

* fix(#4249): never remove on rollback unless a prior manifest proves what predates the install

Three defects in the manifest-driven Codex rollback, all in its removal half:

- ENOENT marked the snapshot usable, arming the removal pass on a FIRST
  install. GSD may have overwritten a user's file at a manifest-tracked path
  there, and no prior manifest records the difference — so rollback deleted it
  where before it merely left it overwritten. Absent, unreadable and malformed
  manifests now all leave the prior set UNKNOWN and skip removal entirely.

- Membership was tested against the map of files whose pre-install read
  SUCCEEDED, so a tracked file that existed but was unreadable read as
  introduced-by-this-install and was removed. Track the prior manifest's paths
  in their own Set and test against that.

- The unreachable "delete the manifest when there was no prior one" branch is
  gone: usable now implies a parsed prior manifest.

Also adds the end-to-end test the aggregate gate was missing — the four Codex
rollback tests drove the closure directly, proving the restore but not the
wiring. installAllRuntimes(['codex','cline']) under an emptied PATH makes
Cline's `env node` entry fail validation for real, and asserts Codex's payload
comes back.

Test preamble (HOME/USERPROFILE sandbox + config-env scrub) is now one helper
instead of six copies. Both new tests are red-checked.

* test(#4249): use unlinkSync, not rmSync, to drop the manifest in a test

lint:ci's raw-fs.rmSync rule points tests at helpers.cleanup for its
Windows-EBUSY retry budget. That budget is for directory trees; this removes a
single file, which unlinkSync says more precisely and the rule does not flag.

* chore(#4249): point the changeset pr field back at the upstream PR

* fix(#4249): use an unambiguous dedup key and surface partial-restore failures

trek-e's 2026-09-08 adversarial pass flagged two findings in the new
entrypoint-validation/rollback code:
- assertConfiguredEntrypoints' dedup key already used a raw NUL
  separator (introduced in ceebb65f2d), but git/Read render NUL as a
  space, so the key looked like a plain-space join to every reviewer
  that read the diff. Replace it with JSON.stringify([configPath,
  scriptPath]) so the separator is visible and unambiguous.
- restoreManagedFileSnapshot's per-file restore catch block claimed to
  'surface the original error' but only swallowed it, matching (and
  widening) the pre-existing #3245 restoreCodexSnapshot pattern. Add
  an actual console.warn using the existing best-effort-warning
  convention, scoped to just this PR's new function.

* fix(#4249): treat a files-less prior manifest as unknown, not known-empty

agy's gemini-3.8-flash-high adversarial pass (round 5) found and I
reproduced empirically: a structurally-valid manifest missing the
files key (e.g. {"version":1}) parses without throwing, so
Object.keys(undefined || {}) silently read as 'zero files predate
this install' instead of the UNKNOWN state the malformed-manifest
guard exists to produce. Rollback's removal pass then deleted every
GSD-owned file the failed install's own manifest listed, including
ones that predated it — the exact data loss the #4249 CodeRabbit
malformed-manifest fix was supposed to prevent, reachable through a
JSON.parse success instead of a failure. Route the shapeless case
into the same catch-all UNKNOWN path via an explicit shape check.
Regression test reproduces the deletion before the fix and confirms
the file survives after it.

Also extend restoreManagedFileSnapshot's removal-pass rmSync and
final manifest-rewrite catches with the same real console.warn
trek-e's round-4 review asked for on the per-file restore catch —
same rollback function, same operator-facing-signal gap.

* docs(#4249): correct which runtimes actually leave a written config on rollback

agy's completeness audit (round 5, holistic pass) caught this new
paragraph claiming 'for every other runtime, the configuration file(s)
already written during that update are left in place' — false for
Claude Code and other settings.json-based runtimes, whose write never
happens on failure (assertConfiguredEntrypoints runs before
finishInstall's writeSettings). Only Cursor/Windsurf/Kimi/Cline
actually match that description, since they persist their config file
inside install() ahead of the gate. Split the one sentence into the
three actual outcomes; matches the PR body's own accurate Before/After
wording, which this doc addition had drifted from.

* fix(#4249): clean up doc/comment mismatches and dead fields from opus review

Opus critical-code-reviewer + ponytail-review pass on the final diff:
- assertConfiguredEntrypoints carried finishInstall's old docblock
  ("Apply statusline config, then print completion message") from
  before this function was inserted between comment and callee.
  finishInstall already has its own accurate #4249 comment, so the
  stale docblock is removed rather than moved.
- checked: number on ConfiguredEntrypointValidationResult and
  error.configuredEntrypointValidation on the thrown error: the first
  had zero consumers anywhere in the repo, including its own defining
  file, and is removed. The second matches an existing repo
  convention (bin/install.js's installerMigrationRollbackFailures,
  #4249 predates this PR) of attaching structured diagnostic context
  to a re-thrown Error even before a consumer exists, so it's kept.
- finishInstall's own assertConfiguredEntrypoints call is a redundant
  backstop on the real production path (installAllRuntimes's aggregate
  call already validates the superset first), but its comment read as
  though this call alone provided the before-the-write guarantee.
  Clarified rather than removed — it's the only gate for a caller that
  invokes finishInstall directly.

* chore(#4249): split the manifest-driven rollback engine out into #4544

Issue #4154 asked the installer to consume a validation failure "through
the existing rollback mechanism, without a second transaction mechanism".
The manifest-driven rollback widening added during review (capture every
path the prior gsd-file-manifest.json claims, restore those bytes, remove
what only the failed install introduced) is that second mechanism on a
plain reading. It is a real fix for a #3245-era gap, but an independent
one, so it moves to its own bug report and PR.

Removed here:
- bin/install.js: the pre-install managed-file capture block and
  restoreManagedFileSnapshot, plus its call sites in
  _codexPreConfigRollback and restoreCodexSnapshot (99 lines).
- tests/configured-entrypoint-validation.test.cjs: the five tests that
  exercise the manifest engine.
- CONTEXT.md and docs/how-to/update-gsd.md: the sentences describing the
  widened restore. update-gsd.md again documents the #3245 surfaces only.

Kept, because it is #4154's own scope:
- the entrypoint-validation gate itself;
- Codex's install() result binding rollbackInstallerMigrations to
  restoreCodexSnapshot (config.toml, hooks.json, skills/gsd-*,
  agents/gsd-*, gsd-core/VERSION);
- the !isMinimalMode gate removal on that snapshot. Binding the closure
  to the result made it reachable for a core/--minimal install, where its
  pass-2 sweeps delete every gsd-* skill dir and agent file the snapshot
  does not claim; an empty minimal-mode snapshot therefore deleted the
  whole surface with nothing to restore.

The surviving aggregate-failure test now asserts on config.toml, a
surface the #3245 snapshot owns, instead of gsd-core/CHANGELOG.md, which
only the manifest engine restored.

Refs #4544

* test(#4249): cover configured entrypoints through the packed install path

#4154's scope lists install smoke coverage alongside the installer gate —
"assert representative configured entrypoints resolve for supported runtime
profiles". The gate itself (assertConfiguredEntrypoints /
validateConfiguredEntrypoints) is unit-covered by in-process install() calls;
nothing proved the property survives npm pack -> npm install -g -> install.js.

Add Cycle 4 to runSmoke. For each of claude and codex — the two distinct
config surfaces GSD writes launch paths into (settings.json, and hooks.json +
config.toml) — run the tarball-installed installer into a throwaway HOME, then
re-read that runtime's own written config and return the new
ENTRYPOINT_UNRESOLVED code when a script path it names does not resolve to a
file. install-smoke.yml already asserts .code == "ok" on the CLI, so the check
becomes a release gate on every matrix host without workflow changes.

The scan re-derives paths from the written config instead of reusing the
installer's own entrypoint list, and test I shows why that matters: a
registration the installer never touched during a run is invisible to the
in-process gate, so the install exits 0 and only reading the config back off
disk catches the dangling launch path.

* ci(#4249): pack a publish-shaped tarball in the install smoke lane

`npm pack` runs prepack/prepare (build:lib); only prepublishOnly runs
build:hooks. hooks/dist is gitignored, so the tarball install-smoke.yml packs
after `npm ci` carries no hook scripts at all — the lane has been smoking a
package that differs from the published one in exactly the artifacts the
lifecycle smoke is supposed to launch.

That went unnoticed because the lane's init runs `--local`, which registers no
statusline and therefore registers no hook whose target is missing. A
`--global` install on the same tarball exits 1 on #4249's own gate
(`gsd-statusline.js (missing)`), which is what the new configured-entrypoint
cycle performs, so without this step the cycle would report INIT_FAILED
instead of checking anything.

Build hooks before packing so the smoked tarball matches prepublishOnly. The
CLI now reports 16 configured entrypoints for claude and 1 for codex instead
of zero.

* fix(#4249): scope Codex's full snapshot restore to entrypoint failures

Binding Codex's result to `restoreCodexSnapshot` made ANY finalize-stage
exception un-install a Codex install that had already succeeded and already
printed its own "Done!" summary — `rollbackFinalizedInstallerMigrations` wraps
the whole `finalize()` body, not just the aggregate `assertConfiguredEntrypoints`
call.

Nothing documents that. `docs/installer-migrations.md#phase-4-installupdate-integration`
scopes finalize-stage rollback to installer *migrations* ("the executor uses the
journal to restore modified paths"), and this PR's own operator-facing paragraph
in `docs/how-to/update-gsd.md` scopes the Codex config.toml/hooks.json/skills/
agents/VERSION revert to entrypoint-validation failures specifically ("If a
script is missing, unreadable, ... For Codex, this reverts ..."). The wide
behaviour is also incoherent as a transaction abort: the same doc says Cursor,
Windsurf, Kimi and Cline keep the config they wrote inside install().

Concretely: `installAllRuntimes(['codex', 'kilo'])` where Kilo's finishInstall
hits EACCES writing kilo.json rolled Codex's config.toml back to its pre-install
bytes — on an update, silently downgrading a working Codex install to the
previous version while the user had just been told it was Done.

Select the rollback by error kind instead. `assertConfiguredEntrypoints` already
tags its error with `configuredEntrypointValidation`, so the full snapshot
restore runs for that error (and anything downstream of it, including
finishInstall's per-runtime backstop) and the installer-migrations-only closure
runs for everything else. The codex result now also exposes that narrow closure
as `rollbackInstallerMigrationsOnly`; `rollbackInstallerMigrations` keeps meaning
the full restore, so the direct-call contract asserted by
tests/codex-config.test.cjs is unchanged.

Adds a regression test that installs codex+kilo together, injects EACCES on the
Kilo permission write by monkeypatching node:fs (restored in a finally — never
chmod 0o000, which root bypasses in CI), and asserts Codex's config.toml keeps
the bytes the successful install wrote. Verified red against the pre-fix
unconditional path.

Cline cannot host this test: its plan is writesSharedSettings:false +
finishPermissionWriter:null, so its finishInstall performs no write and has no
non-entrypoint failure path. Kilo's configureKiloPermissions runs unconditionally
(unlike OpenCode's, it is not GSD_TEST_MODE-gated) and ends in an unguarded
fs.writeFileSync.

* docs(#4249): sync CONTEXT.md's rollback description with the round-6 narrowing

CONTEXT.md still described Codex's rollback as an unconditional bind
to restoreCodexSnapshot after ff13adc00 scoped it to entrypoint-
validation failures via rollbackInstallerMigrationsOnly and the
configuredEntrypointValidation error tag. Caught during the round-6
PR body pass.

* fix(#4249): stop rollbackInstallerMigrations meaning its own opposite

Codex's install() result bound `rollbackInstallerMigrations` to
restoreCodexSnapshot (the FULL pre-install snapshot restore) and put the
actual installer-migrations-only closure behind
`rollbackInstallerMigrationsOnly` — so for one runtime the unsuffixed name
meant the opposite of what it says, and CONTEXT.md had to concede as much
in prose. Invert it: `rollbackInstallerMigrations` is the narrow closure
for every runtime, matching both its name and the meaning it already has
on next, and the snapshot restore gets its own Codex-only field,
`rollbackPreInstallSnapshot`. The selection in
rollbackFinalizedInstallerMigrations collapses to one line and no longer
needs a fallback chain.

Also in this commit, all against the same rollback path:

- Correct the rollbackFinalizedInstallerMigrations comment. It read as if
  the round-6 narrowing prevented any sibling-triggered revert of a Codex
  install the user has already seen "Done!" for. It does not, and is not
  meant to: `wide` is true for ANY entrypoint-validation error from ANY
  runtime, because the aggregate gate is all-or-nothing — an invalid Cline
  entrypoint reverts Codex's snapshot, which
  tests/configured-entrypoint-validation.test.cjs's 'an aggregate
  entrypoint validation failure rolls the Codex install back (#4249)'
  asserts directly. The discriminator is the error's KIND, not which
  runtime owns the failing path. Comment and CONTEXT.md now say that.

- Name the runtime in the "Configured entrypoint validation failed" error.
  ConfiguredEntrypointInvalid already carries `runtime`; the message threw
  it away, leaving an operator of a multi-runtime install unable to tell
  whose entrypoint broke — which matters precisely because the failure can
  revert a runtime that was itself fine.

- Set `configuredEntrypoints: []` explicitly on the copilot-instructions
  early return. Every other branch states the key; this one relied on
  installAllRuntimes' `(result.configuredEntrypoints || [])` defence.
  `[]` is correct, not a workaround: every Copilot hook is an inline
  printf one-liner (GSD_COPILOT_*_HOOK_BASH/PWSH), so there is no
  GSD-managed script or interpreter to resolve.

No behaviour change beyond the error-message text.

* docs(#4249): narrow the smoke scan's config-surface claim to what it checks

RUNTIME_CONFIG_FILES claimed every GSD-managed executable a runtime is
told to launch is registered in one of settings.json / hooks.json /
config.toml, and that nothing else in a config dir is runtime
configuration. Both halves are false as stated. Cline registers its hook
at .clinerules/hooks/PreToolUse — a subdirectory, and not one of those
names (writeClineArtifacts, src/runtime-hooks-surface.cts). Kimi's native
[[hooks]] config.toml lives under resolveKimiHooksTomlDir() (~/.kimi),
a directory separate from Kimi's own GSD configDir — the same gap
installer-migration 007 already documents as structurally unreachable.

The scan is in fact correct for what it runs against: entrypointRuntimes
defaults to claude + codex, whose launch paths do all live in those three
top-level files. Restate the docstring at that scope, name the two known
out-of-scope surfaces, and warn that adding either runtime to
entrypointRuntimes without teaching scanConfiguredEntrypoints about its
surface yields a scan that finds zero entrypoints and proves nothing.
The entrypointRuntimes default comment carried the same overgeneralization
("every other runtime reuses one of them") and is corrected with it.

Documentation only; no code change.

* fix(#4249): complete configuredEntrypoints/rollback shape on unparseable settings.local.json

An internal adversarial review (agy/gemini-3.8-flash-medium, round 8) found
that install()'s settings-json early return for an unparseable
settings.local.json omitted configuredEntrypoints and
rollbackInstallerMigrations from its result, unlike every other branch.
rollbackFinalizedInstallerMigrations reads result.rollbackInstallerMigrations
unconditionally, so this branch silently dropped its own installer-migration
rollback on a later finalize-stage failure.

Completed the return shape: configuredEntrypoints: [] (matching Copilot's
equally-early no-entrypoints-yet return) and rollbackInstallerMigrations
(already in closure scope). Red-then-green regression test added.

* test(#4249): ensure hooks/dist before packing in release-tarball-smoke.install.test.cjs

Same internal adversarial review (round 8): this suite's before() packed the
tarball directly, without the ensureHooksDist() guard every sibling
install-test suite (install.test.cjs, install-minimal-hooks.test.cjs,
mcp-catalog-parity.install.test.cjs) already uses. On a clean tree, or run
in isolation ahead of a suite that builds hooks/dist itself, this suite's
pack would ship a tarball with no hook scripts and fail closed on
SMOKE.INIT_FAILED instead of testing anything.

* fix(#4249): refresh stale test-timings weight for the codex-config split

next's own consolidation split (#4139/#4540) moved tests/codex-config.test.cjs's
heavy install()-pipeline blocks into tests/codex-config-hooks.test.cjs, but the
CI shard packer's weight table (tests/test-timings.json) was never updated:
codex-config.test.cjs still carried its pre-split weight (127783ms, ~18x the
suite mean), and codex-config-hooks.test.cjs — which now holds the #3245 block
this PR extends with its own #4249 install()-pipeline test — had no entry at
all, so the packer would silently underestimate it at the table's median
weight (roughly a 9x underestimate against its real cost).

trek-e's most recent review flagged a Windows shard timeout in-flight on
codex-config.test.cjs, plausibly aggravated by this PR's own addition to that
file before the rebase moved it. Re-measured both files locally (node --test
--test-reporter=tap, max of 3 runs, matching the table's own max-across-streams
methodology) and patched just these two entries — not a full regeneration,
which would need real multi-lane CI data this session doesn't have access to.

* fix(#4249): register configured-entrypoint-validation tests in the conformance-tier lists

next's platform-conformance-tier classifier (#4591/#4598) landed after this
branch's last rebase, so tests/configured-entrypoint-validation.test.cjs and
tests/codex-config-hooks.test.cjs were never classified, failing lint:ci's
gen-platform-conformance-tier --check and both the Linux and macOS conformance
suites.

* fix(#4249): drop codex-config.test.cjs from the #4733 pinned isolated-set expectation

next's #4733 (landed after this branch's last rebase) replaced the static
ISOLATED_HEAVY_FILES set with a threshold derived live from
tests/test-timings.json, and pins the current derived result in
EXPECTED_ISOLATED_UNIT_FILES for regression coverage. That pinned list still
named codex-config.test.cjs, whose own weight this PR already dropped from
127783ms to 189ms (after splitting its heavy install()-pipeline blocks into
codex-config-hooks.test.cjs) — well under #4733's derived 120000ms bar. The
live-computed set correctly no longer includes it; the pinned expectation is
updated to match.

* fix(#4249): name the rollback consequence in the entrypoint-validation error, and prove Cline's file survives it

trek-e's review flagged two Major gaps: the thrown error read identically
regardless of which of three real outcomes a runtime hit (nothing
persisted / snapshot reverted / config left broken on disk), and no test
proved the disclosed "left on disk, unreverted" case for Cursor/Windsurf/
Kimi/Cline — only Codex's revert path was ever asserted.

assertConfiguredEntrypoints now tags each invalid entry with its actual
consequence, mirrored from docs/how-to/update-gsd.md's existing
rollback-matrix disclosure. A new test drives the same aggregate failure
through Cline (whose own entrypoint is the one that fails) and asserts
its hook file is still on disk afterward.

* fix(#4249): close 4 gaps antigravity's adversarial review found in the entrypoint-validation PR

One review pass (gemini-3.8-flash-high via the antigravity review lane)
against this PR's full diff against next, findings independently verified
against source before fixing:

- Copilot's install() return object was the only one of 6 runtime branches
  missing rollbackInstallerMigrations — reachable now that this PR's own
  aggregate gate runs rollback across every result on any runtime's
  entrypoint failure, not just Copilot's own.
- buildHookCommand's unresolved-bash early return skipped track() entirely,
  so a win32 install with no Git Bash silently produced an unregistered
  .sh hook instead of the 'unresolved-interpreter' validation failure
  configuredEntrypointsForHook's own comment said it would.
- release-tarball-smoke.cjs reported a Cycle 4 install failure under
  SMOKE.INIT_FAILED (Cycle 1's code) instead of the already-existing
  SMOKE.INSTALL_FAILED.
- SCRIPT_PATH_RE excluded whitespace to avoid swallowing a shell command's
  trailing args, which also truncated any configDir containing a space
  (e.g. a real "/Users/John Doe/.claude"), silently zeroing the scan.
  Anchored the match on the already-known configDir prefix instead of a
  generic absolute-path guess: removes the ambiguity outright rather than
  patching the character class, and stays a raw-text scan on purpose (it
  catches a writer that emits a path without registering it — a
  JSON.parse of the expected schema would miss exactly that case).

One suggested finding (test-timings.json "missing" the new test file) was
verified false — that table only holds measured CI timings, populated
after a file's first real run — and one Ponytail suggestion (a
JSON.stringify dedup key) was rejected as it would reintroduce a real, if
narrow, key-collision risk for no benefit.

* fix(#4249): fix fork CI red from a stale changeset pr field and an unquoted docs/ comment

changeset-lint requires pr: to match the PR it runs on (16 on the fork,
not the eventual upstream number) — rehearsal-branch convention already
established earlier in this PR's history.

lint-docs-guard-registration's quote-pairing heuristic doesn't require the
docs/ path itself to be quoted — it flags a file once ANY quote-delimited
span containing "docs/" appears anywhere in it, alongside any real fs read
call. A comment ending "...update-gsd.md's rollback-matrix paragraph"
supplied the closing quote character (the possessive apostrophe) the
heuristic paired with an unrelated single-quoted string earlier in the
file. Reworded to avoid the unquoted apostrophe next to the path.

* chore(#4249): point the changeset pr field back at the upstream PR

Fork rehearsal (PR #16) is green; the real target for this changeset is
upstream PR #4249.

25d1cb916f fix(#4721): give worktree cleanup-wave's merge its own timeout, report merge_timed_out, and restore the index a killed merge leaves staged (#4766)
* fix(#4721): give cleanup-wave's merge its own timeout, report merge_timed_out, and restore the index a killed merge leaves staged

`worktree cleanup-wave` ran `git merge --no-ff` under the module-wide
DEFAULT_GIT_TIMEOUT_MS (10 s) that is sized for plumbing calls. The merge is
the one call in the wave that runs user hooks, so a repo whose
pre-merge-commit hook is a test-suite gate lost every code-bearing executor
merge. Three things went wrong at once, each fixed here:

1. Budget. The merge now passes an explicit timeout —
   DEFAULT_MERGE_TIMEOUT_MS (10 min), overridable via deps.mergeTimeoutMs.
   Every other git call in the wave keeps the module default; the shared
   constant is untouched, because every other caller is exactly what its
   10 s comment describes.

2. Reason. A merge that does time out blocks on `merge_timed_out`, and its
   stderr names the budget and says the hook may still be running, instead
   of `merge_failed` carrying whatever the hook had printed before git was
   killed — which made a healthy executor branch look broken.

3. Residue. A merge killed during its hook has already staged the merged
   tree into the primary's index but never wrote MERGE_HEAD, so
   `git merge --abort` finds nothing and repoRootStillMidMerge (#2852)
   reads the primary as clean while the executor's whole diff sits staged
   against the old HEAD; a `git commit` from that state squashes the
   executor's history into one parent. After any failed merge the wave now
   reads `git diff --cached --name-only`; anything staged is the merge's
   own (git refuses to start a merge when the index differs from HEAD), so
   it runs `git reset --merge` — restores exactly those paths, keeps
   unrelated unstaged edits — and re-reads. Restored paths are reported as
   WAVE_CLEANUP_WARNING.MERGE_RESIDUE_RESTORED and the wave continues; a
   still-dirty or unreadable index reports MERGE_RESIDUE_LEFT_STAGED and
   halts the remaining entries, the same repo-level carve-out an
   unfinished merge takes.

Tests: five mock-driven rows (budget wiring incl. the deps override, the
timeout classification with restore, the no-reset control for an ordinary
refused merge, an unrestorable residue halting the wave, an unverifiable
index failing closed) plus a real-git row that runs a sleeping
pre-merge-commit hook under a 1 s budget and asserts HEAD unmoved, index
and worktree clean, the executor branch intact — with the same fixture
merging cleanly under the default budget as its negative control. Two
existing #2852 rows gain a handler for the new post-failure index read.

* fix(#4721): gate the residue restore on the timeout, re-apply a merge autostash, and correct the hook census

Three findings from the pre-file adversarial review of the previous commit,
each driven on real git before changing code:

1. A merge git REFUSED ("your local changes … would be overwritten") also
   leaves no MERGE_HEAD — and that refusal is exactly what a pre-existing
   dirty primary index earns. The residue restore read that index as the
   merge's own and `reset --merge`d the operator's staged work away
   (driven: a staged edit to an unrelated file was discarded and reported
   as "restored"). The restore now runs ONLY when the merge timed out; a
   refusal is an immediate exit, never a timeout, so on that path nothing
   is read or reset.

2. `merge.autoStash=true` lets a merge start on a dirty index by parking
   the work in MERGE_AUTOSTASH, which a killed merge never re-applies.
   `git reset --merge` moves that stash into the stash list; the wave now
   runs `git stash pop --index` afterwards (the outcome `merge --abort`
   gives an autostashed merge), and reports
   WAVE_CLEANUP_WARNING.MERGE_AUTOSTASH_UNRESTORED (path null) when the
   pop fails or the autostash state could not be read — the work stays in
   the stash, the index is clean, the wave continues. Because of this the
   reset runs on a timed-out merge even when the index reads clean.

3. The merge is not the only hook-running git call in the module:
   `worktree add` runs post-checkout and every ref update runs
   reference-transaction. It is the only call that runs the commit-family
   hooks, which is what the budget is for. Comments and docs say so now.

Tests: the "ordinary merge_failed" control becomes the regression row for
finding 1 (strict mock — a `diff --cached` or `reset --merge` on a refused
merge throws), plus a mock row for the autostash pop (dirty and clean
index, pop success and failure), and two real-git rows: a refused merge
over pre-existing staged work leaves it byte-identical, and a killed merge
under merge.autoStash restores the executor residue AND puts the
operator's staged work back. The real-git hook now sleeps 4 s against a
1.5 s budget for margin on slow runners. The two #2852 handlers added
earlier are removed — the residue read no longer fires on their path.
Negative control: 4 of the 10 #4721 rows fail on the previous commit.

* fix(#4721): key the residue restore on a killed merge, and re-read the index after a failed autostash pop

Two more findings from the continuation review, both driven:

1. An externally delivered SIGTERM leaves the same staged/no-MERGE_HEAD
   state as the timeout, and the seam reports it as exitCode null + signal
   with timedOut false — so the timeout-only gate skipped the restore on a
   state it was written for. The gate is now "killed": timedOut, or a null
   exit code with a signal. A refused merge still exits with a code and is
   still never touched. The reason stays merge_failed for a signal kill.

2. A failed `git stash pop --index` keeps the stash entry but can leave
   conflict entries (UU) and partially applied paths, after which the next
   merge fails on "you have unmerged files"; the code returned halt:false
   on the strength of the pre-pop recheck. The index is now re-read after a
   failed pop and a dirty result halts the wave as merge_residue_left_staged
   alongside the merge_autostash_unrestored warning.

Also driven and now documented rather than changed: a kill that lands once
MERGE_HEAD exists (inside commit-msg) is the ordinary #2852 abort path —
`git merge --abort` restores the tree and re-applies an autostash itself,
unstaged, as git does for any aborted autostashed merge.

Tests: the pop-failure mock row now asserts the post-pop re-read and gains
a conflict-leftover variant that halts; a signal-kill mock row; a real-git
row with the sleeping hook moved to commit-msg (timed out, no residue
warnings, MERGE_HEAD cleared, primary clean). 414 pass.

* fix(#4721): key the kill gate on the seam's signal, not on a null exit code

The shell projection seam normalizes a signal death to exitCode 1 and
carries the signal alongside (`_spawnResult`: `result.status ?? 1`), so the
previous `exitCode === null && signal` gate could never fire in production
and the unit row that covered it modelled a shape the seam does not emit
(caught in the round-3 review). The gate is now `timedOut || signal`; a
refused merge exits with a code and no signal. The mock row uses the real
shape, and a mocked spawnSync signal death driven through the compiled seam
reaches `reset --merge` and reports the residue restored.

Also: three comments that still said "at its budget" / "runs user hooks" /
"the index is clean", and the CLI-TOOLS sentence that reserved
`merge_failed` for refusals and conflicts, now name the signal case.

2f0e99f9e0 fix(#4377): opt in to project-relative includes for local installs (#4425)
* enhance(#4377): opt-in project-relative includes for local installs

A local install wrote the includes that point at GSD's own files as absolute
paths — whatever the installer resolved at install time. For one checkout
that is invisible. Across git worktrees it is not: each worktree gets its own
.claude/ copy, but all of them point back at the checkout that ran the
installer, so a worktree runs its own gsd-tools.cjs while reading workflow
prose from a different checkout. Update that one checkout and every other
worktree is running new instructions against an old engine, with nothing to
stage the update with.

--relative-includes (or GSD_RELATIVE_INCLUDES=1) makes a local install emit
`@.claude/gsd-core/...`. Opt-in, and staying opt-in: absolute works for a
single checkout, which is most people, and flipping the default would change
every existing local install to solve a problem those users do not have.

The prefix is the runtime's own localConfigDir descriptor value, never a
literal — the same value resolveScope joins onto the cwd to produce the
install target, and the same one the rewrite engine already uses for its
./.claude/ -> ./<dir>/ substitutions. Copilot and Antigravity have shipped
this shape for local installs since they were added, with hardcoded .github/
and .agents/; this is that behavior, derived rather than written down.

Six seams compute a path prefix and all six had to be threaded, which is why
the opt-in travels through the environment the way --portable-hooks already
does: one variable they all read cannot fall out of sync the way six
signatures can.

The launcher shim deliberately keeps its ABSOLUTE fallbacks. It probes
gsd-tools through ${CLAUDE_CONFIG_DIR:-$HOME/.claude} and one such default
per runtime; those are shell word expansions, not includes, and a relative
value there resolves against the shell's cwd rather than the project.
Trading an include that points at the wrong checkout for a path that points
at nothing is not a fix. All three rewrite paths mask ${VAR:-default} spans
before substituting and restore them after, and the mask only runs when the
prefix is relative, so an absolute install is byte-for-byte unchanged.

Every unexpressible case falls back to absolute: no opt-in, a global install,
a missing dir name, the configHome.kind === 'none' sentinel, an absolute
descriptor value, or one climbing out of the project with '..'.

* chore(#4377): add changeset for project-relative local includes

* fix(#4377): compare against POSIX-normalized roots in the install e2e arms

The emitted prefix is POSIX-normalized by design — it is substituted into
markdown @-references, which use forward slashes universally, so a backslash
would leak into shipped content (#1615). The e2e arms compared against the
raw temp root, which on Windows is `D:\a\...` and appears in no emitted file.

That reddened the control arm on the windows shard, and it was worse than a
red: the negative arm ("nothing references the checkout") was passing
VACUOUSLY there, because a string that cannot occur is trivially absent. Both
now go through the same normalization, so the Windows lane asserts what the
Linux lane does.

* fix(#4377): tolerate a resolved temp root, and make the e2e diff self-diagnosing

Two changes, one confirmed and one to stop guessing.

Confirmed: the emitted content carries the RESOLVED root, not the spelling
mkdtemp handed back. Reproduced on Linux with a symlinked install root —
236 emitted files carry the realpath, zero carry the link path. macOS has
this structurally, since /var is a symlink to /private/var. Comparisons now
go through both spellings, or the negative arms pass vacuously: "nothing
references the checkout" is trivially true when the string being searched
for cannot occur.

Not confirmed: the macOS shard reported ~every workflow file differing in
the "differ ONLY" arm while the five arms around it passed, and the
assertion printed a list of filenames — which says a difference exists
somewhere across 236 files and leaves the reader to guess which bytes. I
cannot reproduce that platform locally, and guessing turns one CI round-trip
into four. The assertion now reports the first divergence as text: the file,
the byte offset, and a bounded window of both sides.

* fix(#4377): strip the longest root spelling first in the install e2e diff

The macOS failure was my test corrupting its own comparison, not a product
defect. /var/folders/…/X is a SUBSTRING of /private/var/folders/…/X, so
stripping the unresolved spelling first matched inside the resolved one and
left the /private prefix glued to what followed:

  @/private/var/…/X/.claude/gsd-core/…  ->  @/private.claude/gsd-core/…

a string present in neither install, which is why all 236 files "differed".
Sorting the spellings longest-first consumes the whole occurrence, and the
short form then has nothing left to match. Proven in isolation on the exact
macOS shapes: short-first yields @/private.claude/…, longest-first yields
@.claude/….

The self-diagnosing assertion added in the previous commit is what found
this — it named the file, the byte offset, and printed both sides, so the
corrupted string was visible rather than inferred from a list of 236
filenames. Keeping it.

06845717fe feat(#4740): make the Loop Host Contract role partition normative and enforced (#4742)
* test(#4740): pin the per-step role-family partition

Failing-first coverage for the Loop Host Contract role partition. At this
commit crossCheckRoleFamilies does not exist, so the rows throw
"crossCheckRoleFamilies is not a function" -- the RED proof they bind to
behavior rather than restating it.

ADR-894 section 3 assigns roles per step but parenthesises the assignment as
"(illustrative roles)", and nothing enforced it. The only thing standing in the
way was a single deepEqual in this same file, which is editable prose.

Rows cover: each step's own family accepted; a strict subset accepted; a
foreign role rejected at every step; an unknown role rejected; an unknown step
failing CLOSED; capitalization not silently matched; every offending role
reported rather than only the first; and purity, because buildContract puts the
same array into the generated contract.

Two rows exist because an earlier cut of this suite was vacuous. The purity
fixture is deliberately UNSORTED -- an alphabetically-sorted fixture cannot
fail an in-place sort(), and the mutant was being killed by three unrelated
rows instead. A parity row asserts ROLE_FAMILY and ROLE_TO_AGENT cover the
exact same role-name domain, both directions: they are parallel constants over
one domain, so divergence is the generative-fix class CLAUDE.md names.

Every negative row asserts the offending ROLE NAME and the STEP NAME appear in
the message. A count-only assertion survives a mutant that reports the wrong
role, which the 80% Stryker gate would surface only after a full CI round-trip.

* feat(#4740): reject a cross-family agent-role declaration

Orchestration and execution are distinct functions of the loop and must not
drift into one another. That partition was real but unenforced: ADR-894
section 3 calls its own role assignment "illustrative", and the generator
accepted anything. Adding orchestrator to execute-phase.md's agent-roles line
compiled, --check passed once regenerated, and capability-validator.cjs then
began accepting into:"orchestrator" at every execute point.

ROLE_FAMILY maps every role to one of orchestration, planning or execution.
EXPECTED_FAMILY_BY_STEP gives each of the five steps exactly one family.
crossCheckRoleFamilies rejects a cross-family role, a role outside the
vocabulary, and an unknown step. It reports every offender, not the first.

It fails CLOSED on an unknown step, deliberately diverging from
assertPointsCoverage's "unknown step -- caught elsewhere". For points that is
true: the canonical-set and duplicate checks catch it. For roles there is no
second net, so failing open would leave an unknown step as the one input that
bypasses the gate.

crossCheckRoles' orchestrator exemption is untouched. ROLE_TO_AGENT maps roles
to agent FILES and the orchestrator is the host, owning none -- admissibility
and agent-file presence are separate concerns with separate checks.

Additive to section 3's existing rule that contribution.into must be a member
of the step's agentRoles, which is unchanged. That governs what a CAPABILITY
may target; this governs what a WORKFLOW may declare. No capability is
affected, and all five workflows already declare single-family sets, so the
gate is green on the commit that introduces it.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* docs(#4740): make the ADR-894 role assignment normative

Section 3 parenthesises its per-step role assignment as "(illustrative roles)".
That word was accurate about the list's PURPOSE -- it illustrated the shape of
a generated contract entry -- and wrong about its STATUS, because the
assignment was load-bearing from the moment the generator consumed it. Read
literally it makes the partition an example rather than a rule.

Appended as a dated in-place section per docs/contributor-standards.md, which
records that an accepted ADR is never rewritten and names this the default
pattern. Section 3's original body is untouched.

The amendment states the three disjoint families, the one family each step
admits, that a step may declare a strict subset but never outside it, and why
this is a clarification rather than a new decision: the contract is generated
from the workflow markers "so it cannot drift into a lie", and all five
workflows have always declared single-family sets. What was absent was any
statement that it is required, and any check that it holds.

It also pins the distinction that is easy to re-merge: contribution.into being
a member of agentRoles governs what a CAPABILITY may target and is unchanged;
the family rule governs what a WORKFLOW may declare. The CONTEXT.md glossary
entry for the Loop Host Contract records the same, beside the agent-reference
drift guard it already documented.

* fix(#4740): stop injecting the orchestrator procedure into executors

claude-orchestration declared a contribution at execute:wave:pre with
into:"executor". loop-hook-dispatch.md defines a contribution as "inject
fragment.inline verbatim into the context for the role named in into", so its
267 lines were injected into EXECUTOR prompts whenever the capability was
enabled. Those lines are orchestration end to end -- construct a wave manifest,
resolve the dispatch backend, invoke the Workflow tool to spawn executors,
bridge per-agent results into the merge chain. An executor can act on none of
it.

Retargeting to into:"orchestrator" would not have been a fix. ROLE_TO_AGENT
carries no orchestrator entry by design: the orchestrator IS the host, and the
host's procedure lives in execute-phase.md. A step's agentRoles enumerates
agents a capability may inject context INTO, so adding orchestrator there would
model the host as an injectable agent -- the same category error pointed the
other way, and it would need an exception carved into the partition the same
issue just made normative.

So the defect is the mechanism, not the label. A contribution injects into an
agent's context; "replace step 3's inline dispatch loop" is a change to what
the HOST does. The contribution channel was serving as a host-behaviour
directive because it was the only channel available at an execute point.

The entry is removed. plan:post into:"planner" is correct and untouched. The
procedure is preserved verbatim at docs/workflow-backend-dispatch.md inside the
capability -- it is the only copy in the repo -- and is no longer injected
anywhere.

Consequence, not softened: the Workflow backend now has no loop wiring.
Detection, emission and config remain and the design is intact, but nothing
dispatches it. Under the separation ADR-1143 itself asserts it never had a
legitimate channel; ADR-1143's own audit already records the end-to-end path
has never been exercised. Wiring it properly needs a host-level mechanism that
does not exist today.

* fix(#4740): invert the stale execute:wave:pre registry assertions

Removing the contribution left four surfaces asserting or describing the old
state. Caught by an isolated review before a verification run was spent, which
is the point of reviewing first: the first of these was a guaranteed CI red.

execute-wave-post-gate-pipeline-e2e asserted against the REAL generated
registry that byLoopPoint['execute:wave:pre'] held exactly one contribution
with capId claude-orchestration. It now holds zero. Inverted to assert exactly
0 -- not a vague >= 0 -- and the #2285 comment above it now explains the
current state rather than the one it was written for.

CONTEXT.md's Claude Orchestration entry claimed two contributions at wired
points. It is now one, and the entry's execute:wave:post label was already
wrong before this change: the manifest said execute:wave:pre. Rewritten to one
plan:post contribution, why the execute-point one was removed, and where the
procedure now lives.

One assertion in claude-orchestration.test.cjs could not fail. It tested for
the prose "(into the executor)" while the doc says "(`into: executor`)", so no
plausible wording matched it and the paired plan:post assertion was carrying
the row. Replaced with a check on the structural claim, and proved RED by
restoring the two-contribution wording before reverting.

The moved procedure keeps section headings that speak as a live contribution --
"When this contribution is active", "Why execute:wave:pre". Preserving the body
verbatim was deliberate, so the headings stay and an editor's note under the
header explains why they read that way.

A sweep of all 17 files referencing byLoopPoint found no further siblings: the
remaining hits are a synthetic capability fixture and an empty-points test that
already expected no active hooks, both correct before and after.

bbdf7e8e84 chore(#4654): add local/no-unconfined-path-join and drain it to zero — Phase 4 of #4636 (#4674)
* chore(#4654): add local/no-unconfined-path-join and drain it to zero

Phase 4 of epic #4636 — the ratchet, and the phase that makes the epic hold.

THE MEASUREMENT THAT RESHAPED THE PHASE. An AST census (the repo's own parser,
not grep) found what the epic never enumerated: ADR-4650 named seven containment
implementations; `src/` alone held roughly 24 more hand-rolled gates across ~13
files, several guarding a write or an `fs.rmSync`. Two verified by reading rather
than pattern-matching — `research-store.cts` comments its own as "ensure the
resolved file path stays inside the store dir" immediately before a write, and
`capability-lifecycle.cts` gates `fs.rmSync` with one.

So the epic's Done-when "one containment predicate, used at every site" was FALSE
when Phase 3 reported it satisfied. It is true now: the rule is clean across
src/, scripts/, gsd-core/bin/ and hooks/ with an EMPTY allowlist.

WHY NOT THE RULE THE ISSUE PROPOSED. #4654 proposed flagging `path.join` whose
first argument is a managed root and whose later arguments derive from argv. That
is a taint analysis over 2046 call sites, in ESLint, without type information;
"derives from argv" is not locally decidable. Any approximation either floods or
is trivially evaded, and a rule that fires on hundreds of correct sites earns an
allowlist of hundreds — the opposite of a ratchet. What is actually duplicated is
the COMPARISON, not the join, and that has one recognizable shape.

  Arm 1  X.startsWith(Y + sep)            the hand-rolled containment idiom
  Arm 2  a containment predicate called as a bare statement, answer discarded

Arm 2 is the issue's "asserts the result was narrowed, not merely that a helper
was called". Its example `validatePath(x, root).resolved` is already
structurally impossible — Phase 3 un-exported `validatePath` — so the remaining
expressible failure is ignoring the answer, which is the defect that recurred
five times in this epic. The census found exactly one live instance
(`milestone.cts:1643`); it now returns the proven `ContainedPath` so consumers
stop re-deriving the path the comment above it was extracted to stop them
re-deriving.

The rule deliberately does NOT try to catch validate-one-path-use-another where
the answer is used but a different variable flows onward. That needs flow
analysis; the branded `ContainedPath` from Phase 3 is the defense there, and the
two are complementary.

PER-SITE FAMILY CHOICE, NOT A DEFAULT. Phase 3's lesson binds: collapsing a
lexical site onto the realpath family broke four tests and was caught only by the
matrix. Every migrated site was triaged individually. The six
installer-migrations tree-walks and the six capability-lifecycle gates take the
LEXICAL family because their operands are already realpath-resolved and they
deliberately treat the final component as a link; boundary sites take realpath.

TWO SITES WITH AN INVERTED CONTRACT, which a mechanical swap would have broken.
`installer-migrations.cts:127` and `runtime-artifact-install-plan.cts:144` REJECT
`target === root` by contract, while the canonical comparison ACCEPTS it. Swapped
naively, a migration could `rmdir` the user's config root and a third-party
descriptor could write at configHome itself. Both keep `=== root` as an explicit
additional arm alongside the predicate call — the predicate decides containment,
the call site keeps its own extra condition (ADR-4650 decision 6).

ONE DUPLICATE DELETED OUTRIGHT: `planning-inspect.cts`'s `isWithinRoot` was
byte-identical to `isContainedIn` and said so in its own docstring.
`isContainedIn` is now exported for callers that have already resolved both
operands and need only the comparison, with a doc note that a caller which has
NOT resolved them must use a full predicate instead.

THE MARKER, AND WHY IT IS NOT THE ALLOWLIST. Nine sites are justified holdouts and
carry `// allow-handrolled-containment: <reason>` with a mandatory, reviewable
reason. Two justifications: (a) not a containment decision — an ancestor-walk loop
condition, sub-repo grouping, worktree identity matching, declared-path coverage;
(b) it IS containment but the canonical predicate is unreachable —
`capability-validator.cjs` is a committed pre-build `.cjs` and the compiled
`security.cjs` is untracked build output, so requiring it would break a fresh
clone. `scripts/lib/drift-scan.cjs` runs under `lint:ci` with the same exposure.
The marker was renamed from `allow-lexical-prefix-match` mid-phase because that
name asserted only (a) and would have stated something false at the (b) sites.

A marker suppresses BEFORE the violation counter increments, so a file whose
every occurrence is marked still reports `staleAllowlistEntry` — otherwise a
drained entry lingers and silently re-permits the site later.

DEMONSTRATED RED, per #4654: a hand-rolled copy reintroduced into a real `src/`
file made `npm run lint` fail with the rule's full guidance message; removing it
returned the tree to clean. Both halves recorded — red alone proves nothing,
since a rule red for an unrelated reason looks identical.

DISCLOSED: `defaultRequireFromInstallRoot` (gsd-tools.cjs) previously carried two
distinct rejection messages and two manual realpath calls; routing it through
`tryWithinRoot` collapses them to one message, and a missing module now surfaces
as MODULE_NOT_FOUND rather than ENOENT. No test asserts either message. The
security property is preserved and slightly strengthened — the candidate is
realpathed and containment re-checked, and the dangling-symlink oracle closure
comes along with it.

* docs(#4654): record the containment ratchet in CONTEXT.md and the security model

Both entries previously described the seam without the thing that keeps it a
seam. They now state what the rule bans, and — more usefully for whoever reads
this next — what it deliberately does NOT attempt: deciding per path.join call
whether an argument came from user input. That question is not locally
decidable, and an approximation across ~2000 join sites would earn an exemption
list of hundreds, which is the opposite of a ratchet.

Also records the marker's two legitimate justifications and that its reason is
mandatory, so the escape stays reviewable rather than becoming a mute button.

Glossary gate 270 refs exit 0; install-tree goldens and CONTEXT-INDEX.json
regenerated and confirmed byte-identical rather than assumed — which also
confirms eslint-rules/ is not a shipped path.

* fix(#4654): close review findings and the two matrix failures

MATRIX FAILURE 1 — a collapsed message broke a negative-proof test, and my
evidence for collapsing it was wrong. I searched tests/ for the literal string
"resolves outside its install root", found nothing, and reported that no test
asserted it. The test matches a REGEX SUBSTRING, /outside its install root/, so
the literal search missed it. What broke was "NEGATIVE PROOF: a symlinked module
pointing OUTSIDE the install root is not loaded" — the test guarding the exact
property I claimed was preserved. defaultRequireFromInstallRoot now does both
checks again with both messages byte-identical, each routed through the
canonical predicate, which is better than the original since that hand-rolled
both comparisons.

MATRIX FAILURE 2 — shipped migrations are checksum-locked, and a marker cannot
serve there. migrationChecksum hashes plan.toString(), which INCLUDES comments,
so a suppression marker inside a plan body drifts the baseline exactly as an
edit does. Measured: with markers in place, two of the four still differed from
their committed checksums. The four shipped bodies are now byte-identical to
next, and the rule's config excludes those four paths BY NAME rather than by a
directory wildcard, so a NEW migration is still covered. Six containment
comparisons stay un-ratcheted there; that gap is recorded in the rule's Known
gaps, in CONTEXT.md and in the security model rather than left implicit.
Justification (c) is removed from the marker's documented reasons, because a
marker was proven unable to express it.

ADVERSARIAL REVIEW — the sharpest finding was that the rule banned the CORRECT
shape while permitting the incorrect one: startsWith(root) with no separator is
the genuinely unsafe form, since it accepts a sibling such as root-evil, and my
own test blessed it as valid. Flagging every bare startsWith would swamp the
rule, so that stays a STATED gap rather than a silent one. Closed for real: the
template-literal spelling, which the census never saw because it only inspected
plus-concatenation — that surfaced TWELVE more sites, now triaged and migrated.
A separator reached through a const alias is now resolved via scope analysis.
And isContainedIn, exported in Phase 3, was missing from the discarded-result
set, so a bare no-op call went unflagged on the one function the epic funnels
through.

SECURITY REVIEW — the marker could over-suppress two ways: a block comment
worked identically to a line comment, and one marker silently covered every
violation sharing its line. It now requires a Line comment positioned after the
flagged node ends, so it anchors to the node it trails. Four sites had dropped
an unreachable-but-deliberate equality rejection against the root; each is
restored as the call site's own arm. eslint.config.mjs still documented the OLD
marker token, which my rename missed — it would have sent the next author in
circles.

A FALSE GREEN, recorded because it nearly stuck: lint:ci reported exit 0 from a
stale eslint cache while twelve real violations existed. Every lint check here
now clears the cache first.

* fix(#4654): anchor a suppression marker to the violation it actually trails

The matrix caught this; my own test caught it, on its first execution. The case
"two violations on one line: trailing marker suppresses only the one it trails"
expected 1 error and got 0 — both were suppressed.

ROOT CAUSE: the anchoring accepted any Line comment on the node's line whose
range started at or after the node's end. A trailing marker at the END of a line
sits after EVERY node on that line, so that condition held for all of them.
"After the node" does not identify WHICH node the marker trails. The fix reads
as correct and is not.

FIX: deferred reporting. Violations accumulate during traversal instead of being
reported immediately; at Program:exit each marker claims exactly ONE pending
violation — the one on its line whose end is nearest before the marker begins —
and every unclaimed violation is then counted and reported. One marker, one
suppression. An earlier violation sharing the line is still reported, which is
the property the security review asked for and the previous attempt only
appeared to deliver.

The counter now increments at flush time rather than during traversal, so a
suppressed occurrence still does not keep an allowlist entry alive.

AND A TOOL THAT SHOULD HAVE EXISTED BEFORE THE FIRST MATRIX RUN. `node --test`
is hard-blocked here, so this rule's test file could only ever be executed on
the remote matrix — which is why a broken anchoring shipped into a run. ESLint's
programmatic Linter API is not a test runner, and exercising the rule through it
verifies every case locally in seconds. All 24 now pass locally, including the
two-on-one-line case that failed remotely. That loop should have been built
before the rule was first sent to the matrix rather than after it failed twice.

* chore(#4654): backfill PR 4674 into the changeset and complete 70-docs.json

The phase gate requires enablementSequence and the Diataxis quadrants; 70-docs
now carries both, with the how-to quadrant skipped for a stated reason rather
than an empty field. The audience for this deliverable is a contributor who
trips the rule, and the task-oriented guidance reaches them in the ESLint
message itself — which names the correct predicate, says how to choose between
the realpath and lexical families, cites the Phase 3 regression caused by
choosing wrong, and gives the marker syntax. A docs/how-to page would be a
second, driftable copy read by nobody at the moment of failure.

enablementSequence is recorded as what it actually is: a VERIFICATION sequence,
not an enablement one. The rule is never off, so there is no off-to-on
transition to describe.

scripts/lint-docs-required.cjs now passes (ok_docs_updated) — it could not
evaluate against the mandated pr:0 placeholder.

d1d9ee85a5 feat(#4142): thread convention through the completion-path membership seam (#3644)
* feat(#2761): gated heading-intro selection + one bracket identity grammar

Foundation. Two owner-level changes plus a federated convention resolver; no
reader consumes them yet.

1. GATED SELECTION, not an ungated widening.

   Widening every heading matcher requires the claim "no legacy ROADMAP contains
   a `[CODE.MM]` bracket followed by a digit", and that is false:
   `### [RFC.2119] 5:`, `### [v1.0] 2024:`, `### [ADR.612] 3:` and
   `### [ISO.8601] 2026:` are ordinary headings, and a widened reader claims each
   as a phase — moving phase_count and total_phases and adding W006 on projects
   that never opted in. No narrowing rescues it: the premise is about documents
   we do not control.

   `phaseHeadingPrefixSrcFor(baseline, convention, capturing?)` selects the
   pattern SOURCE at construction time. A project whose resolved
   `phase_id_convention` is not exactly 'bracket' compiles the same source string
   it compiled before. `baseline` is explicit because whether a site spells the
   any-bracket prefix or a bare `Phase\s+` is a fact about that site's history:
   handing the wider grammar to a bare site retro-grants tolerance it never had,
   in both directions — warnings appear, and a warning that fires today vanishes.

   Both bracket forms CAPTURE. `[GSD.999] Phase 07:` previously matched through
   the base alternative, which captures nothing, so a reader saw no bracket, fell
   back to the legacy token rule, and counted a labeled icebox heading while
   excluding the label-less one beside it — two derivations of one ROADMAP
   disagreeing.

2. ONE bracket identity grammar, one width rule.

   The milestone width is reconciled with the emit validator: pad2 output, so
   two digits or 3+ with no leading zero. Earlier spellings diverged in both
   directions — admitting `002`, which the validator rejects, and a bare `0` pad2
   never produces — and the section recognizers accepted `[GSD.2]`, which SCOPED
   a milestone no phase heading could then resolve into, recreating the
   on-disk-count fallback this epic removes. An unpadded bracket is now uniformly
   malformed: it scopes nothing, bounds nothing, sections nothing. W005 on its
   directories is the surfacing signal.

   The milestone field is boundary-anchored, so a malformed run cannot match by
   its prefix (`GSD.002-01` read as sentinel `00`). Recognition stays
   case-insensitive because readers compile `/i`, but identity helpers match
   `[A-Z]`, so a captured id is folded first — otherwise `### [gsd.999] 07:`
   failed every sentinel test. The qualified key shares the width, the `(?=-|$)`
   boundary and the single-sub-phase shape of the directory token, because
   phaseTokenMatches returns unconditionally on a qualified hit: a key matching a
   directory isPhaseDirName rejects would be a final wrong answer.

3. resolvePhaseIdConvention federates workstream -> root exactly as
   config-loader does — including that root is a fallback only when a WORKSTREAM
   is active, so a project-scoped directory stands alone. loadConfig cannot serve
   this: it merges against CONFIG_DEFAULTS and drops keys it does not know, and
   this key is not among them. It governs the bracket-selection reads ONLY.

PHASE_HEADING_PREFIX_SRC is left byte-identical: PR-1 shipped it, nothing
consumes it, and it is superseded rather than redefined.

* feat(#2761): roadmap.cts selects its heading grammar from the convention

Six matchers build their intro through the gated selector, and
cmdRoadmapAnalyze / cmdRoadmapGetPhase / getRoadmapPhaseWithFallback each
resolve the convention ONCE per command and thread it down.

Three sites take the any-bracket baseline (they already tolerated
`[anything] Phase N`); three take label-only (they spelled a bare `Phase\s+`).
Handing the wider grammar to a label-only site retro-grants tolerance it never
had — and not only by adding matches: on a legacy repo an unchecked
`- [ ] **[v1.0] Phase 05: Thing**` bullet would start SUPPRESSING the W006 that
fires today.

Sentinel handling under bracket ADDS a rule rather than replacing one: a
bracketed heading is a sentinel when its bracket milestone is reserved
(`### [GSD.999] 01:`) OR when its token is, so the engine-wide 0/999 backlog
convention keeps applying to `### [GSD.02] 999:`. Replacing the token rule let a
mid-migration ROADMAP — bracket headings plus a legacy backlog block, exactly
the content this epic targets — add entries to the progress denominator. The
captured id is folded before the identity test, so a lowercase
`### [gsd.999] 07:` is excluded too.

The DIRECTORY read is threaded too. `cmdRoadmapAnalyze` resolves the convention
once and hands it to all four of its heading/checklist patterns, but the single
`phaseTokenMatches` call that decides `disk_status`, `plan_count`,
`summary_count`, `has_context` and `has_research` was left two-argument — so
every canonical `{CODE}.{MM}-{PP}-slug` directory read as `no_directory` with
zero counts, on the PR's own headline verb, while the SAME build resolved those
same directories correctly in three other places on the same repo (W006/W007 via
phaseTokenFromDir, `state json` via the milestone filter, and the W021
milestone-complete read through this very helper's three-argument form). It
failed ONLY for the directory shape the convention exists to name: a
mid-migration bracket repo carrying legacy `01-one` dirs resolved fine, which is
why nothing caught it. Measured, bracket vs its flat-legacy twin:
`[["01","no_directory",0,0],["02","no_directory",0,0]]` against
`[["01","complete",1,1],["02","planned",1,0]]`.

The oracle is the twin, computed in the same test run, plus exact literals —
`grep disk_status tests/adr-612-*` was zero hits before this, so neither the fix
nor a future regression had any gate at all.

Disclosed: a ROADMAP written in bracket form before config.json is switched
reads as empty rather than mis-counted. Silent invisibility during the migration
window is the deliberate trade against claiming phases on projects that never
opted in.

* feat(#2761): validate.cts selects its grammar; gated directory recognition

The W006/W007 feeders take the resolved convention as a threaded parameter.
These sites carry the letter-tolerant `[\w][\w.-]*` capture, which makes them
where an ungated widening does the most damage: `### [RFC.2119] 5:` enters
roadmapPhases as a phantom and becomes a W007 "in ROADMAP.md but no directory on
disk" on a project that never opted in.

buildRoadmapPhaseVariants also surfaces the tokens borne ONLY by sentinel-bracket
headings. Surfaced rather than filtered in place because roadmapPhases feeds both
a membership check and a missing-directory warning, and only the latter should
ignore an icebox item.

That set is OCCURRENCE-AWARE, and the subtlety is load-bearing: roadmapPhases is
a TOKEN set, so `[GSD.999] 01` and `[GSD.02] 01` collapse to one entry. Keying
suppression on the token alone let an icebox heading silence a REAL phase that
happens to share its number — a false negative strictly worse than the warning it
removed. A token is suppressed only when no non-sentinel heading bears it.

Directory recognition is added as gated FUNCTIONS beside the exported RegExp
constants, which stay byte-identical: the `{CODE}.{MM}-` prefix is
string-indistinguishable from the letter-prefixed-decimal family this repo
documents as ambiguous, and folding a branch in changes those constants' answers
on exactly that family. A RegExp constant has nowhere to attach a gate.

The recognizer mirrors the emit grammar and delegates the token to the canonical
owner, so recognizer and resolver agree on rejected input as well as accepted.
Both functions throw on a non-string, matching the call pattern they replace.

buildRoadmapPhaseVariants' CHECKLIST scan is capturing, like its heading twin
and like the sibling checklist scan in roadmap.cts, and for the reason that one
states: the bracket id has to ride along or the sentinel filter is blind to
`- [ ] **[GSD.999] 01: Icebox**`. Left un-capturing, the scan called every
checklist token REAL, and the occurrence-aware un-suppression loop then deleted
the icebox token the HEADING scan had correctly marked sentinel — so `validate
consistency` warned that a bracket ICEBOX phase had no directory, in the HOUSE
ROADMAP shape where an icebox appears as both a bold bullet and a detail
heading. `validate health` stayed silent on that same repo, so the two verbs
disagreed — which is the disagreement `sentinelPhases` exists to close.

Both directions are pinned, because the failure mode of a careless fix here is
the opposite one: a real phase sharing a sentinel's token must still warn. It
does, in all four shapes that attack it (sentinel heading + real bullet,
lowercase sentinel, sentinel after the real heading, colon-less bullet).

* fix(#2761): count bracket headings, and retire them, in both derivations

Both `total_phases` derivations select their grammar from the resolved
convention, in one commit — cmdStateSync already carries the comment that it
mirrors buildStateFrontmatter "so both report consistent percents (#3242 Bug B)",
so teaching one and not the other ships that divergence.

The #1514 retirement filter widens WITH the counter it protects. The canonical
gesture strikes the checklist BULLET and leaves the detail heading intact, so a
bracket-form retirement went undetected and the phase stayed in the denominator
forever. That is half a fix alone: the retired key is compared against
phaseKeyFromDir, which called extractPhaseToken with no convention. Both halves
land here.

Under bracket the sentinel token rule composes as the full engine set {0, 999},
so this counter agrees with `roadmap analyze`, which has always excluded both —
otherwise the two derivations report different numbers for one ROADMAP and the
changeset's "excluded from every count" is false as written. The LEGACY path
keeps its pre-existing 999-only rule: widening it there would move legacy totals,
so the two stay split off the bracket path exactly as they are today.

The sync-side assertion reads the PERCENT sync writes into the STATE.md body, not
the frontmatter total_phases. Sync's own counter never reaches that field — the
read derivation writes it — so asserting the frontmatter after a sync measures the
read path twice and lets a mutation to the write-path guard survive.

* feat(#2761): verify.cts bracket-coherence W021 + selected milestone-complete read

The shipped milestone-prefixed W021 gate keeps its ROOT-only config read,
verbatim base semantics. Federating it silently moved a legacy convention's
answer in BOTH directions on workstream repos — a W021 that fires at base
vanishing, and one that is silent at base firing. resolvePhaseIdConvention
governs the new bracket-selection reads only.

B6, the milestone-complete check, keeps its ungated POSTURE (bug-557 pins it
with an empty config) but selects its grammar from the convention. Inferring
'bracket' from the shape of a matched bracket ran a repo-failing check against a
legacy ROADMAP that merely contained `### [RFC.2119] 5:`. Directory resolution
widens with the heading read, so a bracket repo whose phases are on disk stays
silent, and a bracket sentinel is not reported as unstarted.

checkBracketCoherence is advisory and gated. Anchored to tokenizeHeadings so
fenced examples cannot warn and heading level is structural. Its scope rules each
close a way it silently did nothing or fired wrongly: only a genuine MILESTONE
heading opens or closes a section (a `### Notes` used to reset scope and disable
both sub-checks); a legacy `## v3.0` DOES close it; an M-NN or letter-suffixed
phase heading raises missing-bracket and CONTINUES; a bare `#### 2026:` is not a
phase; the full h2-h6 range is processed. Its section recognizer shares the one
milestone width, so an unpadded `### [GSD.3] 05:` can no longer be a phase to the
id grammar and a section to the section grammar at once, silently re-scoping
every warning after it.

validate consistency suppresses bracket sentinels in its missing-directory
warning — the two verbs disagreed, health suppressing via notStartedPhases while
consistency did not. The legacy reading is untouched, including its pre-existing
wart that `### Phase 999:` still warns there.

* fix(#2761): scope the milestone by its bracket; select the disk-side filter

Two roadmap-parser reads, both of which made a bracket project's totals track
the disk instead of the ROADMAP.

The ADR pins the bracket milestone heading as `## [GSD.02] Foundation` — a name,
no version — but scoping matched STATE's `milestone: v2.0` STRING against a
heading, so the canonical form matched nothing and total_phases fell back to the
directory count. The rule was re-derived in THREE places: extractCurrentMilestone
plus two `milestoneBounded` guards; fixing one left the others falling back
regardless, so they are now one gated helper. It matches the CANONICAL padded
spelling only — accepting `0*N` bounded a milestone whose phases were invisible,
which un-suppressed a progress percent computed off an unscoped disk count.

getMilestonePhaseFilter's heading scan becomes the 14th selected read. On a
bracket ROADMAP it collected nothing, so the filter degraded to pass-all and
buildStateFrontmatter counted every other milestone's directories — making the
bracket convention strictly worse than the M-NN one it supersedes on the property
that matters most: totals must track the ROADMAP, not the disk.

The DIRECTORY side of that same filter is selected with it. Teaching only the
heading scan was half a fix and a worse one: `milestonePhaseNums` became
non-empty, so the pass-all degrade stopped firing, but no bracket directory could
satisfy the three legacy dir checks (numericRe fails on `GSD.02-05-five`, the
custom-id match captures the project code `GSD`, and stripProjectCodePrefix does
not strip a dotted prefix). Every bracket directory was rejected, and
completed_phases / total_plans / completed_plans / percent all collapsed to 0
while `state sync` went on writing a percent off the unfiltered disk — `state
json` reporting 0% on the same repo, in the same second, that STATE.md's body
called 67%. That is the #3242 Bug B divergence this PR exists to avoid, and
total_phases could not show it: `Math.max(phaseDirs.length, roadmapPhaseCount)`
floors it at the ROADMAP count no matter how many directories are rejected.

The dir side matches on the milestone-QUALIFIED id, delegated to the owner's
gated `phaseTokenMatches(dir, id, 'bracket')`, not on the bare token: READING-B
puts the milestone in the bracket, so `GSD.01-01-old-one` and `GSD.02-01-one`
share the token `01` and only the qualified key separates them. The qualified ids
are kept in their own set — a hyphen in `milestonePhaseNums` would flip
`roadmapUsesHyphenedIds` and silently move the LEGACY dir path on a bracket repo
— and the branch is ADDITIVE: on a miss it falls through to the three legacy
checks, so a bracket project carrying legacy-shaped directories reads unchanged.

Both are resolved lazily and gated, so the legacy path pays neither a config read
nor a second scan and cannot change answer. The scoping call is also GUARDED:
resolvePhaseIdConvention reaches planningDir, which throws a plain Error for a
GSD_PROJECT/GSD_WORKSTREAM segment carrying `/`, `\` or `..`. At base the only
planningDir call in extractCurrentMilestone sits inside the STATE-read try, so
the function returned normally on such an environment; an unguarded one here let
that escape and broke the never-throws invariant that getRoadmapPhaseInternal and
getMilestoneInfo three hundred lines below carry #2245 / ADR-227 notes about.
Unreachable through the CLI — GSD_WORKSTREAM is rejected up front by the
workstream-name policy and GSD_PROJECT throws identically at base — but reachable
by any in-process embedder, which is precisely who that invariant is for. The
filter's own resolve call was already inside its try and is unaffected.

The milestone-qualified key is formed only for a token that is itself a bracket
phase token. `${bracketId}-${token}` is a string SPLICE, so a mid-migration
heading carrying an M-NN label — `### [GSD.02] Phase 02-01:` — spliced to
`GSD.02-02-01`, which the qualified-key grammar reads as milestone 02 / phase 02:
the `-01` truncated, both such headings collapsing to one key, and the heading
claiming `GSD.02-02-two`, the directory it does NOT name, while rejecting
`GSD.02-01-one`, the one it does. The guard drops those headings back to the
unqualified legacy path, restoring the base ACCEPTANCE VECTOR exactly — pinned
against the milestone-prefixed reading of the same ROADMAP, which is
base-identical on this shape.

Scoped precisely, because the fixture moves one number that the guard does not
touch: `total_phases` on it reads 1 at base and 2 here. That is the bracket
heading COUNT this PR exists to add, not the splice — measured identical with and
without the guard, and identical to what the canonical `### [GSD.02] 01:`
spelling does on the same fixture (both read 2 with zero directories on disk,
where base reads 0). The claim is base-equivalent ACCEPTANCE, not a
base-equivalent reading.

One consequence is stated rather than fixed: a heading whose token carries a
hyphen still puts that hyphen into milestonePhaseNums and so still flips
`roadmapUsesHyphenedIds`. Base does the same for that spelling, so preserving it
is what keeps the shape base-equivalent; excluding the token would have moved
answers versus base on malformed input. The comment at the qualified-set
declaration is corrected to claim only what is true — it keeps QUALIFIED IDS out
of that flag's input, not hyphens in general.

The oracles ship with it, and they are the five numbers, not the one: the parity
gate now asserts total_phases, completed_phases, total_plans, completed_plans AND
percent, on both derivations, on two fixture shapes (one milestone; two
milestones with stale prior-milestone directories on disk). The oracle is the
flat-legacy twin, built in the same test run and compared number for number,
plus exact literals so a shared wrong answer cannot pass.

The oracle SUBSTITUTION is itself pinned. The M-NN spelling of these shapes could
not serve, because buildStateFrontmatter's #2445 de-dup key captures only a
directory's leading integer and collapses `02-01-one` / `02-02-two` /
`02-03-three` to one — measured [3,0,1,0,0] against the flat-legacy twin's
[3,2,3,2,67], identically at base and before this fix, and structurally
unreachable from the bracket key space. That reasoning is only sound while it
stays true, so a characterization test holds the M-NN reading down on the two
numbers that do not depend on which directory wins the mtime race. Widen the
de-dup key and it fails, instead of quietly invalidating the changeset's
disclosure.

Also adds the call-site pin. The structural table pins transcription against the
selector; it cannot see a call site whose BASELINE ARGUMENT is wrong. Flipping
verify.cts's milestone-complete site to the wider baseline grants a
fires-on-every-repo check tolerance it has never had, and every behavioural test
still passed. The pin reads the shipped sources and asserts the mode at each of
the 14 sites, count-exact.

* test(#2761): pin the bracket read surfaces in the parity gate

This gate exists because #2043 fixed one bug across five hand-edited copies of a
rule and #2232 was the residual that survived, because a later reader could not
tell the copies were one rule. PR-2 adds two consumers, so they belong here.

Surface 7 — the heading read and the directory read must agree about WHICH phase
a `MM-<seg>` pair names, across the shared width corpus, and the bracket and
legacy spellings of one heading must yield the same token.

Surface 8 — the two bracket directory readers, in BOTH directions. Agreement on
ACCEPTED input was already pinned; agreement on REJECTED input is where they
actually diverged.

* chore(#2761): changeset

Disclosures for the PR body (deliberate, not defects):

- phase_id_convention is not a CONFIG_DEFAULTS key, so loadConfig drops it and
  cannot serve as the convention resolver however the file is federated. This PR
  ships its own workstream->root resolver; adding the key and its value enum is
  later-slice work.
- Convention matching is strictly === 'bracket'. A misspelled value reads as
  not-configured and the project keeps legacy behaviour silently.
- An UNPADDED bracket milestone (`[GSD.2]`) is malformed: it scopes nothing,
  bounds nothing, sections nothing, and is not a phase id. W005 on its
  directories is the surfacing signal.
- WIDTH UNIFICATION MOVED FOUR MERGED PR-1 EXPORT ANSWERS on non-canonical
  inputs, none of which toDir can emit and none of which had a bracket caller at
  base:
    isSentinelPhaseId('GSD.0-01',    'bracket')  true  -> false
    isSentinelPhaseId('GSD.0999-01', 'bracket')  true  -> false
    getMilestoneFromPhaseId('GSD.2-01',   'bracket')  'v2.0' -> null
    getMilestoneFromPhaseId('GSD.002-01', 'bracket')  'v2.0' -> null
  The canonical pad2 sentinel spelling `[GSD.00]` still tests true.
- FLAG TO MAINTAINER: docs/adr/612:132 reads "Sentinel behavior (0.x / 999.x ->
  milestone null) is preserved". After the unification that holds for the
  canonical `00` spelling only, not for a bare `[GSD.0]`. ADR wording is yours;
  flagging the tension rather than editing it.
- The bracket sentinel rule COMPOSES with the legacy one — a bracketed heading is
  a sentinel when its bracket milestone OR its token is reserved. Under bracket
  the state-side token rule is the full {0, 999} set so both derivations agree;
  the LEGACY path keeps its pre-existing 999-only rule, unchanged.
- validate consistency's legacy reading is untouched, including the pre-existing
  wart that `### Phase 999:` warns there while validate health suppresses it.
- find-phase still cannot resolve a bracket phase directory. phase-locator.cts is
  outside this PR's module set. Sibling PR #2559's matchPhaseDirs calls
  phaseTokenMatches without a convention, so whichever slice lands second must
  thread it through.
- Four of the five bracket readers scan raw ROADMAP content, so a bracket heading
  inside a fenced code block is read as a phase. Pre-existing for the legacy
  spelling; parity, not a new class.
- roadmapPhaseLookupSources gained no bracket source: nothing emits a
  milestone-qualified query into it yet.
- roadmap validate remains a separate, unfederated convention reader.
  Pre-existing and base-identical, but two verbs can disagree about the active
  convention on one project.
- _diskScanCache keys on cwd while the values it caches are now
  convention-dependent. Not reproducible through the CLI; pre-existing for the
  workstream dimension, widened here. Stated as inconclusive.
- A ROADMAP written in bracket form before config.json is switched reads as empty
  rather than mis-counted — the deliberate migration-window trade.
- THE READ AND WRITE PERCENTS STILL DIVERGE ON A MULTI-MILESTONE REPO, and that
  divergence is MIRRORED under bracket rather than closed. buildStateFrontmatter
  applies the milestone filter; cmdStateSync does its own fs.readdirSync and never
  calls it, so on a repo carrying prior-milestone directories the read path
  reports the SCOPED percent and the sync body reports the WHOLE-DISK one.
  Measured on the true base build (d04592de), flat-legacy spelling, 3 in-scope
  phases with 1 complete plus 2 stale prior-milestone dirs: `state json`
  [3,1,3,1,33], sync body 60%. The bracket twin of that repo now reads the same
  two numbers — 33 and 60. Scoping the sync counter would move every legacy
  repo's percent, which a bracket read-path PR must not do. The gate pins both
  sides, so the mirror cannot silently become a one-sided fix.
- THE PARITY ORACLE IS THE FLAT-LEGACY TWIN, NOT THE M-NN ONE, and that is a
  measurement finding rather than a preference. buildStateFrontmatter's #2445
  de-dup key captures only a directory's LEADING integer, so the M-NN dirs
  `02-01-one` / `02-02-two` / `02-03-three` all key to `2` and two of the three
  are dropped before they are ever counted: base reads [3,0,1,0,0] where the
  flat-legacy twin of the same repo reads [3,2,3,2,67]. Present identically at
  base and at HEAD, untouched here, and structurally unreachable from the bracket
  key space — `GSD.02-01-one` does not match that pattern at all, so every bracket
  directory keys to its own name. The source line already carries a
  `phase-id-owner:` sanction recording the divergence. Mirroring it under bracket
  would mean manufacturing a collision that cannot occur, so the gate compares
  against the flat-legacy spelling, which is uncontaminated. This paragraph is
  itself pinned: a characterization test holds the M-NN reading on the two
  numbers that do not depend on which directory wins the mtime race, so widening
  the de-dup key in a later slice fails the suite rather than silently making
  this disclosure false.
- THE `phaseTokenMatches` CALL-SITE CENSUS, stated so the remaining gaps are
  auditable rather than implied. 13 call sites outside the owner (phase-id.cts).
  THREE are three-argument: verify.cts:2229 (the W021 milestone-complete read,
  already was), roadmap.cts:436 (`roadmap analyze`'s directory lookup, threaded
  by this PR) and roadmap-parser.cts:792 (the disk-side milestone filter, added
  by this PR). The other TEN are two-argument and stay that way — phase.cts ×5
  (220, 277, 444, 585, 1547), phase-locator.cts:62, smart-entry.cts:243,
  init.cts:1414, milestone.cts:551 and verify.cts:2467. All ten are untouched by
  this PR and base-identical.
  One of them sits in a file this PR DOES edit, so it is named rather than left
  to a reader's grep: verify.cts:2467, `verify schema-drift <phase>`. Measured on
  a bracket repo across base / pre-fix branch / this HEAD, all three agree on all
  three argument forms — `verify schema-drift GSD.02-01` and `… 01` both report
  "Phase directory not found" on every build, and `… GSD.02-01-one` resolves on
  every build through the exact-directory-name fallback. So the user-visible
  shape of what stays broken is: a bracket phase is addressable there by full
  directory name only, exactly as at base. Threading the convention into a
  function this PR never touched, in the last round before ship, is the wrong
  trade; it is where the same one-argument fix goes next, alongside
  milestone.cts:551 and init.cts:1414.
- A BRACKET HEADING WHOSE TOKEN CARRIES A HYPHEN (`### [GSD.02] Phase 02-01:`,
  a mid-migration spelling) forms NO milestone-qualified key, and therefore
  scopes through the unqualified legacy path — base-equivalent ACCEPTANCE, which
  is the claim, and not a base-equivalent reading: `total_phases` on that shape
  moves 1 -> 2 for the same reason it moves on the canonical `### [GSD.02] 01:`
  spelling, because counting bracket headings is what this PR does. Such a token
  still flips `roadmapUsesHyphenedIds`, as it also does at base. The comment at
  the qualified-set declaration now claims only that narrower, true thing.

The `pr:` field carries the sub-issue number as a placeholder — it must be
updated to the real PR number when the PR is opened.

* chore(#2761): point the changeset at PR #2867

* test(#2761): fast-check properties for the convention-selection layer

CONTRIBUTING.md mandates a generative property test for parser/bijective-contract
changes; PR-2 shipped six example-based files and none. This adds the missing
layer, scoped to what PR-2 actually contracts — WHICH pattern each reader
compiles, decided by the resolved `phase_id_convention` — rather than restating
PR-1's grammar round-trip properties, which already live in
tests/adr-612-bracket-grammar.test.cjs.

Four properties: P1 an opted-in repo reads the ADR-canonical label-less bracket
heading/dir and a non-opted-in repo is byte-blind to the identical input; P2
every non-bracket convention agrees with the hand-transcribed BASE source over
generated content, including bracket-DOTTED legacy prose (`[RFC.2119] 5:`) that
must never be claimed as a phase; P3 nine per-field mutations are rejected and
the one case variation folds instead; P4 both sides of a phase comparison derive
the same key under the same convention.

Generators template every input from raw primitives — nothing is seeded through
renderPhaseId/toDir, the p2() tautology that made #2258 round 1's property test
structurally unable to find B1. Domain reaches past 99 into the 3+-digit branch
(round 2's numArb-capped-at-99 miss), forces sub-phases in at weight, and pins
both sentinel milestones.

Falsified against the COMPILED lib, not the source: five deliberate mutants
(gate never fires; gate always fires; milestone width widened to \d+; the #612
convention forwarding dropped from phaseKeyFromDir; extractPhaseToken's bracket
branch ungated) each fail the specific property that should catch them —
16/2, 16/2, 15/3, 17/1, 17/1 pass/fail — and the lib restores byte-identical.

An earlier draft of P2 held vacuously: its base regex omitted the markdown
furniture the selected one carried, so every realistic `### Phase NN:` line
matched neither side. The gate-always-fires mutant did not kill it. Both are now
compiled through one function, and that mutant kills P2.

* test(#2761): adversarial malformed bracket tokens across the tolerant readers

The existing boundary coverage stopped at shapes the emit grammar rejects
(unpadded `[GSD.3]`, wrong-case, `12A`). It never exercised a STRUCTURALLY
broken token — a non-numeric milestone, a bracket that never closes, a bracket
nested in another — which is the input a tolerant reader is most likely to
half-read, and the one the PR's own regex commentary is explicit about.

read-tolerance (roadmap heading scan + validate's dir and variant builders):
ten malformed headings, each asserted to be read as a phase by NO convention and
to give the opted-in repo the same answer as the legacy one; the corpus driven
through `roadmap analyze` end to end; malformed DIRECTORY names asserted
unrecognized and non-throwing on all four conventions; and the two variant
builders asserted to agree, since a widening that reaches only one splits
`validate consistency` from `validate health` (the #3242 Bug B shape).

coherence (verify.cts W021): the same six broken shapes asserted to raise no
W021 of their own AND not to re-scope the W021 that follows them — the G2
failure mode reached from a different shape, where a heading that is not a phase
but IS read as a section silently moves later warnings onto the wrong milestone.

Both files gain a pathological-input time bound. Nested quantifiers over a long
unclosed bracket are the classic ReDoS shape and two commits on next (#2828,
#2944) were CodeQL-flagged for exactly that, so the bound is asserted rather
than argued from reading the pattern. The probes themselves parse no regex.

* docs(#2761): document "bracket" as a phase_id_convention value

The row listed only `"milestone-prefixed"` and `null`, so after two shipped
slices (#2258 grammar, this PR's read path) the convention had no documented
enum value. CONFIGURATION.md is also a top-10 historical co-changer of both
src/verify.cts and src/state.cts and was absent from this PR.

The row states the boundary rather than the ambition: `"bracket"` changes the
READ path only, there is no migrator and no emit yet, and a project on any other
value compiles the patterns it compiled before. That keeps the docs honest for
the two releases before PR-3 and PR-4 land, instead of describing a convention a
user cannot yet migrate to.

* chore(#2761): retype the changeset Added, drop the docs-exempt marker

`Fixed` was wrong by CONTRIBUTING.md's own definition — a fix restores
documented behavior, and bracket read tolerance is the second slice of a
capability that did not exist before #2258. The type also carried a
`docs-exempt` marker, and `Fixed`/`Security` are exempt from the docs-required
lint, so the typing had the effect of routing around a gate this change should
pass. It now passes it: `lint-docs-required` returns ok_docs_updated on the
CONFIGURATION.md row added in the previous commit.

Body gains one sentence pointing at that row and restating that `"bracket"` is a
read-path opt-in until the migrator and write path land.

* test(#2761): pin the version-less bracket milestone scoping gap; narrow the claim

The changeset asserted that milestone scoping "recognises the ADR-canonical
`## [GSD.02] Foundation` heading and applies to the phase DIRECTORIES too." A
CLI probe on that exact heading form falsifies the second half: with no `vN.N`
in the milestone heading the directory side does not scope, and directories from
BOTH the prior and the later milestone are admitted. Measured 4 dirs counted
where the milestone declares 2.

Every bracket fixture in the suite writes `## [GSD.02] v2.0: …`, so nothing
covered the form the ADR actually specifies — and the state.cts doc comment
calls that version-less form canonical.

Mechanism, in extractCurrentMilestone: the bracket scope branch selects the
right currentSection, but `preambleCutoff` keys off a pattern requiring a
version or status emoji, so a version-less roadmap falls back to the current
milestone's own offset and every PRIOR milestone lands in the preamble — whose
phase-stripping regex only strips `Phase N:`-labelled headings, so bracket phase
headings survive it. Independently, `computeSectionEnd` accepts a boundary only
on a version/emoji heading, so the section runs to EOF and every LATER milestone
is swept in. Two sites, bidirectional.

Not fixed here: it changes milestone scoping, which is shared with the legacy
path. Five characterization tests pin today's reading plus a versioned CONTROL
proving the version string is the only difference, and the changeset sentence is
narrowed to what the code does. The DEFECT assertions are written to be
INVERTED by the fix, not deleted — that inversion is its regression proof.

* docs(#2761): re-anchor the branch's own cross-file line citations after the rebase

Three of this branch's code comments cite sibling call sites by line number, and
the rebase onto 178ec000 moved two of the three targets:

  roadmap-parser.cts  validate.cts:210 -> :218   (const g = capturing ? 1 : 0)
                      state.cts:1715   -> :1752  (const bg = … 'bracket' ? 1 : 0)
  roadmap.cts         verify.cts:2229  -> :2355  (phaseTokenMatches 3-arg form)

`state.cts:1715` had drifted 37 lines and now lands on the retirement skip, not
the capture-offset idiom the sentence is about — the citation read as evidence
for a claim the cited line does not support.

planning-workspace.cts's `config-loader.cts:618/:649` was checked and is still
correct; left alone.

Comment-only. Build, drift guard and the bracket suites re-run unchanged.

* fix(#2761): scope the version-less bracket milestone heading too (B1)

computeSectionEnd and the preambleCutoff scan in extractCurrentMilestone
(roadmap-parser.cts) only recognized a milestone boundary heading that
carried a vN.N token or a status emoji. The ADR-canonical bracket
heading (## [GSD.02] Foundation) carries neither, so on that shape
computeSectionEnd fell through to content.length (sweeping every LATER
milestone into scope) and preambleCutoff fell back to the current
milestone's own offset (leaking every PRIOR milestone's bracket phases
into the preamble, whose Phase-N: strip regex never matches them).

Under the bracket scope branch, both sites now also accept a
`#{1,2}\s+\[CODE.MM\]` boundary, built from phase-id.cts's BRACKET_ID_SRC
(single owner of the bracket-id grammar) rather than a re-typed literal.
`#{1,2}` is the deliberate discriminator: a bracket PHASE heading is
level 3 and shares the same `[CODE.MM]` prefix, so a `#{1,3}` boundary
would swallow it too. Reachable only when bracketScopeConvention ===
'bracket' was already resolved (i.e. the bracket scope branch actually
fired), so version-bearing/emoji headings and non-bracket conventions
take the exact pre-existing code path byte-identically — confirmed by
the full adr-612 suite staying green.

Inverts the four DEFECT assertions in the
"#612 PR-2 CHARACTERIZATION: a version-less bracket milestone does not
scope" describe block (tests/adr-612-bracket-phase-counting.test.cjs)
into their regression-proof form, per the block's own doc comment, and
reframes the describe title/comments accordingly. Corrects the
.changeset/2761-bracket-read-tolerance.md fragment, which described the
directory-side version-less gap as an open, un-closed bound.

* fix(#2761): thread sentinelPhases into validate health's W006 loop (B2)

cmdValidateHealth's W006 loop (src/verify.cts) destructured only
roadmapPhases from buildRoadmapPhaseVariants, not sentinelPhases —
unlike cmdValidateConsistency, which already skips sentinelPhases with
the identical guard a few hundred lines up. A heading-only bracket
icebox/pre-milestone entry ([GSD.999] / [GSD.00]) therefore gained a
false W006 "no directory on disk" from validate health while validate
consistency correctly stayed silent on the very same ROADMAP — the two
validators contradicting each other.

Threads sentinelPhases through and skips it before the existsOnDisk
check, mirroring the consistency guard exactly. Gated the same way
sentinelPhases already is (empty unless phase_id_convention is
'bracket'), so a legacy repo's W006 reading — including its own
pre-existing wart where a legacy `### Phase 999:` still warns on both
verbs — is untouched; confirmed by the existing "INHERITED WART,
unchanged" test staying green.

Adds the paired-agreement regression test (#612 PR-2 B2 describe block
in tests/adr-612-bracket-read-tolerance.test.cjs): a sentinel-only
bracket roadmap must produce no missing-directory warning from EITHER
validator, plus a CONTROL proving a real phase with no directory still
warns on both. Confirmed red (health false-W006) against the pre-fix
code before applying the fix.

Corrects the .changeset/2761-bracket-read-tolerance.md fragment, which
described the asymmetry as already closed and in the wrong direction
(it credited validate health with already staying silent, when health
was the one falsely warning).

* test(#2761): pin mixed-shape preamble cutoff and boundary heading levels

Closes two self-flagged coverage gaps in the B1 fix (commit 08d5b0c4)
ahead of adversarial review. No src change — all three new tests are
green against the code as committed.

1. earliest-of-either preambleCutoff comparison: only exercised where
   the version/emoji match and the bracket match happen to land on the
   same heading. Adds the mid-migration mixed shape (version-bearing
   PRIOR + version-less CURRENT) and asserts scoping outcomes (accepts
   booleans + total_phases), not internals.

2. `h.level <= 2` conjunct in computeSectionEnd: provably redundant
   whenever the selected milestone heading is level 2 (every existing
   fixture), since `h.level > level` alone already implies it there —
   a mutant deleting the conjunct would have survived every prior test
   in this file. Adds a level-3 CURRENT-heading fixture (with a real
   PRIOR milestone so the preamble side-channel can't independently
   rescue the truncated phases) that makes the conjunct's deletion
   test-visible, confirmed by hand-mutating a throwaway copy of the
   compiled output (never touching tracked src or the real build) and
   observing the assertion flip. Also pins a level-1 companion case
   (#{1,2} tolerance, not just level 2).

NOT included here: the other mixed-shape direction (version-less PRIOR
+ version-bearing CURRENT) turned out to be a genuine, currently-unfixed
gap — reported separately rather than silently patched or weakened, per
instruction not to touch src while a probe run is in flight.

* fix(#2761): engage bracket boundaries when the current milestone heading is version-bearing (B3, self-caught)

Found during round-2 self-verification of B1 (commit 08d5b0c4), while
closing the mixed-heading-shape coverage gaps flagged in my own review
notes. The B1 fix resolved `bracketScopeConvention` only inside the
`if (headingMatches.length === 0)` gate that also drives SELECTION's
own bracket fallback (which heading counts as "current"). That gate is
correct for selection, but `bracketScopeConvention` also feeds
computeSectionEnd's and preambleCutoff's boundary detection further
down — which accidentally inherited selection's gate instead of having
its own.

Trigger shape: the CURRENT milestone heading is itself version-bearing
(`## [GSD.02] v2.0: Current Milestone`), so the primary version-string
match succeeds immediately — headingMatches.length !== 0 from the very
first check — and the entire bracket-resolution branch was skipped. A
sibling milestone (PRIOR or LATER) that is version-less then got
neither the version/emoji boundary rule (it has none) nor the bracket
boundary rule (never resolved), reproducing the original #612 defect
(total_phases falling back to the whole-disk count) through a
structural shape B1's own fixtures never exercised — every one of them
is uniformly version-bearing or uniformly version-less across all
three milestones, never mixed with CURRENT specifically being the
version-bearing one.

Fix: resolve `bracketScopeConvention` unconditionally, decoupled from
`headingMatches.length`. SELECTION is deliberately left untouched — the
`if (headingMatches.length === 0 && bracketScopeConvention === 'bracket')`
fallback that picks which heading is "current" keeps its original gate
byte-for-byte (confirmed by diff: that line is unmodified). Only the
convention *resolution* moved out from behind it, so boundary detection
can consult it regardless of which branch selected the heading. The
extra `resolvePhaseIdConvention` call this now costs on every
invocation (previously paid only when the version match found nothing)
is the accepted cost: a non-bracket repo still resolves to something
other than 'bracket' (or null on a poisoned env, caught exactly as
before), so `bracketMilestoneHeadingRe` stays null and every downstream
branch is byte-identical to today — confirmed by the full adr-612 +
roadmap-parser + state + verify + health-validation suite staying green
(1260/1260) and the all-version-bearing/legacy fixtures showing no
behavior change.

TDD: tests/adr-612-bracket-phase-counting.test.cjs describe block
"#612 PR-2 B3: bracket boundaries engage even when CURRENT is
version-bearing but a sibling is not" — 4 tests, confirmed red against
pre-fix code (leak-in booleans true/true, total_phases 4) before this
change, green after.

* fix(#2761): reject same-milestone continuation headings as boundaries (B1)

Gate-2 adversarial review Blocker 1: the B1/B3 boundary fired on ANY
#{1,2} `[CODE.MM]` heading, including one bearing the SAME milestone id
as the one currently selected — a version-less checklist/detail split
(`## [GSD.02] Foundation (Phase Details)`, or an ad-hoc continuation
heading) truncated the current milestone's own section instead of
being recognised as a continuation of it. The `(Phase Details)`
re-append only searches VERSION-STRING matches, so a version-less
continuation heading was cut out and never re-appended — a confidently
wrong, non-degraded phase count for a still-incomplete milestone
(repro8 case 1: 1/1/100 instead of 2/1/50; repro5: same, on a fully
version-less roadmap with no sibling milestones at all).

Introduces one shared helper, isBracketMilestoneBoundary(headingText,
level, selectedBracketId), used by both computeSectionEnd and the
preambleCutoff bracket scan, replacing the ungated `h.level <= 2 &&
bracketMilestoneHeadingRe.test(...)` inline check. `selectedBracketId`
(case-folded via phase-id.cts's foldBracketId, matching the branch's
own fold-before-identity convention) is derived from `selected[0]`,
which is the full matched heading line on BOTH selection paths
(version-string and bracket-fallback), so one extraction covers both.

Level cap stays at `level > 2` for now (temporary — ADR-612's content
discriminator replaces it in the next commit); same-milestone rejection
is the change this commit is scoped to.

DEVIATION from the reviewed plan, caught empirically: applying the
same-milestone rejection at the preambleCutoff site (as literally
specified) regressed an existing pin ("boundary heading level: a
level-1 CURRENT milestone heading also scopes correctly") and a
fenced-heading case (repro10 A3) — because preambleCutoff's job is
"where does the earliest milestone-shaped heading sit, scanning from
the TOP of the document," and the selected heading's own occurrence is
always a correct answer to that question regardless of same-id-ness;
rejecting it let the earliest-of-either comparison fall through to a
stray LATER heading instead. `selectedBracketId` is threaded through as
`null` at the preambleCutoff call site for this reason — bracket-shaped
(and, from the next commit, phase-tail) discrimination still applies
uniformly at both sites; only the same-milestone component is
call-site-specific, since it encodes a "keep scanning past this
heading" instruction with no counterpart in a top-of-document search.

Tests: new describe block "#612 PR-2 B1 round-2: a same-milestone
continuation heading is not a boundary" — RED-turned-GREEN fixtures for
repro8 case 1 and repro5, plus PINs for repro8 case 3 (trailing
different-id icebox still terminates) and repro10 A1 (all-version-
bearing + icebox + Phase Details stays exactly 2/1/50 — no double-count
from the same-milestone exclusion interacting with the pre-existing
detailsMatch re-append). syncedTotal()/syncedPercent() assertions
omitted from the repro10 A1 pin: that fixture carries dirs outside the
current milestone, which exposes the SEPARATE Major 1 defect
(cmdStateSync's body percent from an unfiltered disk scan) — asserted
once Major 1 is fixed, not here.

Full suite green (796/796 across the targeted adr-612 + roadmap-parser
+ state files); node scripts/lint-phase-id-drift.cjs clean; eslint
clean on both changed files.

* fix(#2761): bracket boundary discriminates by content, not heading level (B2)

Gate-2 adversarial review Blocker 2: three sites disagreed about which
heading levels are a bracket milestone. The selector
(roadmap-parser.cts's bracket-fallback SELECTION branch,
`^#{1,3}\s+\[CODE.MM\]`) and `isMilestoneBounded` (state.cts) both
admit level 1-3, but isBracketMilestoneBoundary's level cap only
admitted level 1-2 (`h.level <= 2`, from the B1 commit). A `###`-level
bracket milestone heading was therefore SELECTED and BOUNDED but never
TERMINATED: computeSectionEnd ran with level=3, a level-3 SIBLING
milestone survived the pre-existing `h.level > level` (not-deeper)
filter, failed the version/emoji test (version-less), then failed
`h.level <= 2` — falling through to `return content.length` and
sweeping the sibling milestone's own phases into the current one.
Reproduces trek-e's original #612 defect verbatim ("a safe degrade
became a confidently-wrong persisted number") on a heading level the
selector and bounding predicate both already admit (repro2 case C:
4/75% instead of 2/100%; mechanism confirmed directly via repro7 —
extractCurrentMilestone returned the whole 214-byte document).

ADR-612 Decision 1 (docs/adr/612-bracket-phase-id-convention.md:56)
specifies the discriminator as CONTENT, not level: "a phase heading is
a bracket followed by a digit-then-colon ([GSD.02] 05:); a milestone
heading is a bracket followed by a name." Replaces the `level > 2`
rejection with BRACKET_PHASE_TAIL_RE — built by interpolating
phase-id.cts's single-owner phaseHeadingPrefixSrcFor(ANY_BRACKET,
'bracket', false) plus the digit + optional-tag + colon tail every
phase-heading counter in this file already spells, not a re-typed
grammar — and widens the level check to a depth-sanity cap of 3
(mirroring the selector's own `#{1,3}` ceiling; NOT itself a
phase/milestone discriminator). Covers the dotted sub-phase heading
form (`[GSD.02] 05.03:`) via the same `[\w][\w.-]*` token, pinned by a
new fixture — the shape where a regex slip in the tail grammar would
hide.

preambleCutoff's own raw-scan regex is widened from `^(#{1,2})` to
`^(#{1,3})` in lockstep: the outer pattern's level ceiling must track
the helper's cap, or a level-3 PRIOR milestone heading is invisible to
that scan and its own phase heading leaks into the preamble
un-stripped (a real double-count this widening closes, verified
against repro2 case C directly).

The existing "boundary heading level: a level-3 CURRENT milestone
heading still scopes correctly" pin (3e562f12) now passes via a
DIFFERENT mechanism than before — its own neighbours are version-
bearing, so it previously passed via the version/emoji rule (the level
cap was never actually exercised by that fixture, per the round-2
review's own finding); with the content discriminator, the SAME
fixture's level-3 phase headings are now correctly excluded because
they are phase-tail-shaped, not because they are too deep. A
deliberate mechanism change, confirmed by re-running that test green
after this commit.

Also updates the "every selector call site declares the right
baseline" governance pin (adr-612-bracket-heading-selection.test.cjs):
BRACKET_PHASE_TAIL_RE is a new, legitimate ANY_BRACKET call site in
roadmap-parser.cts (always passing the literal 'bracket' convention,
since its only caller is already gated on bracketBoundaryActive) —
EXPECTED count bumped 1->2, with a matching BASE_SITES transcription
entry (identical src to every other ANY_BRACKET site, since the
function is pure).

Tests: new describe block "#612 PR-2 B2 round-2: the bracket boundary
is a CONTENT discriminator, not a level cap" — RED-turned-GREEN for

* fix(#2761): fence-aware preamble cutoff on the bracket branch (Blocker 3)

Gate-2 adversarial review Blocker 3: preambleCutoff's bracket scan used
a raw content.match/matchAll — blind to fenced code blocks — while its
sibling computeSectionEnd (a few lines above it) already consumed
tokenizeHeadings(content), which strips fences. The two halves of one
boundary semantic disagreed about what a heading is.

A fenced markdown example in the preamble containing a bracket heading
(ADR-612's own docs do exactly this) was textually the earliest
`#{1,3} [CODE.MM]` match: preambleCutoff landed INSIDE the fence,
`preamble = content.slice(0, preambleCutoff)` ended with an unclosed
opener, and the unbalanced fence then blinded
getMilestonePhaseFilter's own tokenizeHeadings(scope) call — every
heading in the returned scope vanished, phaseCount degraded to 0, and
the pass-all filter admitted every directory on disk (repro11's
mechanism, confirmed directly: fence count 1/odd, tokenizeHeadings(scope)
-> only "Roadmap"). Regression vs round-1, which had no bracket pattern
to blind and so fell back to the correct heading (repro12 bracket row:
2/1/50 at round-1, 4/3/75 at HEAD).

Fixed by hoisting one tokenizeHeadings(content) call
(currentMilestoneHeadings) shared by computeSectionEnd and the
preambleCutoff scan, which now iterates that same fence-aware token
list instead of a raw regex. HeadingToken.text is already hash-stripped
and trimmed, so isBracketMilestoneBoundary needs no `^#{1,3}\s+`
re-derivation at this site (that spelling would not match h.text — a
note the round-2 review called out explicitly, confirmed while
porting). selectedBracketId stays `null` here, unchanged from the B1
commit's same-milestone-exclusion reasoning.

DISCLOSED, not fixed (explicitly out of scope per the round-2 review's
own minimal-fix note): the LEGACY (non-bracket) anyMilestonePattern
raw-match path shares the identical fence-blindness hazard and stays
byte-identical — a bracket repo whose preamble has a fenced
VERSION-BEARING heading still has the legacy raw-match win the
earliest-of-either min() (repro12's LEGACY control: 4/3/75, unchanged
across base/round-1/HEAD/this commit). Pinned here so a future reviewer
files this as a known, pre-existing gap rather than a new regression.

Tests: new describe block "#612 PR-2 Blocker 3 round-2: preambleCutoff
is fence-aware (bracket branch only)" — RED-turned-GREEN for repro12's
bracket row and repro11's mechanism (fence balance + non-degraded
phaseCount + correct per-directory admission), a PIN for repro12's
LEGACY control (the disclosed gap, explicitly unchanged), and a PIN for
repro10 A3 (a fenced heading INSIDE the current section must still not
terminate it).

Full suite green (1072/1072 across the targeted adr-612 + roadmap-
parser + state + phase-id + markdown-sectionizer files); node

* fix(#2761): scope cmdStateSync's disk scan by milestone under bracket (Major 1)

Gate-2 adversarial review Major 1: `state sync` wrote a Progress
PERCENT computed from an UNFILTERED whole-disk scan, beside the
milestone-scoped total_phases/completed_phases it writes into the same
STATE.md via the refreshed frontmatter (syncStateFrontmatter ->
buildStateFrontmatter, which has always applied getMilestonePhaseFilter
for the READ path). cmdStateSync's own `fs.readdirSync` chain (the
WRITE-path scan) never called the milestone filter at all, unlike
buildStateFrontmatter's identical-purpose scan. One command therefore
wrote two contradictory numbers into one file: on the ADR-canonical
version-less bracket fixture (4 dirs, 3 complete; asserted milestone =
2 phases, both complete), base wrote total_phases:2/completed_phases:2
(correct, from the READ derivation) alongside body Progress 75% (wrong
— from the unfiltered WRITE derivation; repro3).

Fixed by threading `getMilestonePhaseFilter(cwd)` through the same
`.filter()` chain buildStateFrontmatter already applies, gated on
`syncConvention === 'bracket'` (falling back to a pass-all predicate
otherwise) — so totalDiskPlans/totalDiskSummaries/diskCompletedPhases/
syncTotalPhases become milestone-scoped under bracket, byte-identical
under legacy.

DEVIATION (approved, stated plainly): an earlier phrasing of this fix
called for mirroring buildStateFrontmatter's filter UNCONDITIONALLY.
Implemented GATED instead — an unconditional filter would ALSO move
every LEGACY repo's persisted percent, since the milestone-scoping-vs-
whole-disk divergence this closes is engine-wide, not bracket-specific.
The gate keeps legacy byte-identical, which is the binding constraint:
this is a bracket read-path PR, not a legacy behavior change.

Nit 2 (informational, no code change): 10 calls to
extractCurrentMilestone on a legacy repo cost 10 config.json
existsSync + 10 readFileSync (0 before B3); accepted, unmemoized cost,
unaffected by this commit.

Also folds in two minors from the round-2 review:
- Corrects .changeset/2761-bracket-read-tolerance.md: the sibling-
  exclusion sentence now states it holds at any heading level 1-3 and
  across a milestone split over two headings (true again now that
  Blockers 1 and 2 are fixed); the percent sentence states plainly that
  `state sync`'s body percent is now milestone-scoped under bracket,
  and unaffected under legacy.
- Records the read/write scoping divergence at currentMilestoneRawRanges
  (src/roadmap-parser.cts) in a comment: it did not receive B1/B2's
  bracket boundary fixes, currently harmless (its only consumer falls
  back to whole-content mutation, and every mutation there is still
  Phase-labelled-only, not bracket-widened), but live the moment the
  write path is bracket-widened — flagged so a future PR closes it in
  lockstep with that work, not after.

Tests: 6 pre-existing tests in tests/adr-612-bracket-phase-counting.test.cjs
needed fixture updates, not logic changes — they used the default
single directory (`GSD.02-01-setup`, phase "01"), which the SENTINEL/
retirement/mixed-heading fixtures in those tests never declare as a
real phase (only 04/05/06/999/etc are declared). Before this fix,
cmdStateSync's unfiltered scan counted that off-roadmap directory
anyway; after this fix the milestone filter correctly excludes it,
which for several of these fixtures made `state sync` a no-op (the
computed 0% coincided with STATE.md's initial template default) and
broke `syncedTotal()`/`syncedPercent()`'s ability to observe anything.
Updated each to pass an EXPLICIT directory naming one of the fixture's
REAL declared phases, preserving each test's original numerator/
denominator intent. One test — "shape 2 WRITE" — was substantively
rewritten: it was a CHARACTERIZATION of the Major 1 bug itself ("the
DISCLOSED legacy gap, mirrored — not closed"), and now correctly pins
bracket closing to 33% (agrees with the read path) while legacy stays
at the disclosed 60% (unchanged, deliberately, per the gating decision
above).

Full suite green: `npm test` 1449/1449 (0 fail, 0 skipped, 0 todo,
single-shard "all" run — includes issue-2765-brace-expansion-lockfile
passing); `npm run lint:ci` clean (0 errors; 2 pre-existing timing-

* fix(#2761): preambleCutoff identity is offset- and child-aware (round-3 Blocker 1)

Gate-2 round-3 re-verify Blocker 1 (NEW): the round-2 B1 deviation
(39c42a89) threaded `selectedBracketId` as the real value at
computeSectionEnd but as bare `null` at the preambleCutoff scan. The
deviation's rationale — "the selected heading's own occurrence is
always a correct earliest answer" — was right, but `null` disables the
same-milestone check for EVERY candidate, not just the selected one.
Any bracket-shaped heading earlier than the selected milestone was
accepted as a boundary regardless of identity: a same-id checklist/
overview heading preceding the version-bearing selected heading (cases
A, B — the version lands on the LATER half of a split, or a plain
overview heading with no "(Phase Details)" spelling), or a DIFFERENT-id
bracket-shaped PROSE heading with no children of its own sitting above
the current milestone's content (case D — `## [ADR.612] Heading
convention used by this roadmap`). In every case the region between
that false boundary and the real sectionStart was silently dropped —
a completed phase vanished and `state sync` persisted a confident 0%
where base and round-1 both correctly wrote 50%. Regression vs base
AND round-1 (not merely "under-fixed", per the round-3 review's own
severity note).

Fixed with two changes, both scoped to the preambleCutoff scan only
(computeSectionEnd already threads the real `selectedBracketId` and is
untouched):

(a) `h.offset === sectionStart` now bypasses BOTH the same-milestone
    check inside isBracketMilestoneBoundary (passing the REAL
    `selectedBracketId` for every other candidate) and the new child
    rule below — the selected heading's own position is definitionally
    the correct answer, so neither discriminator should run against it
    (rejecting it would mean rejecting the heading against ITSELF).
    Closes cases A and B — verified by the reviewer's own one-liner,
    reproduced here.

(b) New `bracketHeadingHasMatchingChild`: an otherwise-accepted
    candidate (bracket-shaped, not phase-tail-shaped, not the same id
    as the selected milestone) must ALSO have a next-strictly-deeper
    heading carrying its OWN bracket id to count as a boundary. This is
    what a genuine sibling milestone has (its own phase children share
    its bracket id — `## [GSD.01] Setup` / `### [GSD.01] 01: …`) and an
    unrelated bracket-shaped prose heading does not. A candidate with
    no such child at all (childless — e.g. an empty prior milestone, or
    one immediately followed by a same-or-shallower heading) degrades
    to NOT a boundary — over-inclusive, the safe direction: its own
    heading text stays in the preamble, contributing nothing to any
    phase count (not phase-shaped). Closes case D, which (a) alone does
    not — verified: without this rule, `[ADR.612]`'s prose heading is
    indistinguishable from a genuine prior sibling at this site.

As a side effect, also neutralizes Nit 2 (a colon-less `[GSD.02] 05`
heading spuriously terminating the preamble): a colon-less bracket
heading is not phase-tail-shaped so isBracketMilestoneBoundary alone
would accept it, but it is — precisely because it is malformed/
incomplete rather than a real milestone — childless, so the child rule
rejects it too. Pinned.

Known interaction with the fence-blind SELECTION path (disclosed by
the reviewer, not introduced here, tracked for the next commit): when
`sectionPattern` selects a FENCED version-bearing heading (an
extremely pathological shape — a fenced example whose text happens to
match STATE's asserted version), no token exists at `sectionStart`, so
the `h.offset === sectionStart` bypass never fires and the loop falls
through to the ordinary same-id / child-rule checks. This composes
with the round-3 Major 1 fix (next commit) rather than introducing a
new defect — SELECTION itself is untouched by any of this — but is
worth stating plainly rather than rediscovering.

Tests: new describe block "#612 PR-2 Blocker 1 round-3: preambleCutoff
identity is offset- and child-aware" — RED-turned-GREEN for cases A, B
(rv-attack1) and D (rv-attack1b) with syncedTotal()/syncedPercent()
assertions (the persisted 0% is the point), a PIN for a genuine prior
sibling with real children (still excluded), a PIN for a childless
prior sibling (degrades to not-cutting, over-inclusive/safe), a PIN
for the colon-less Nit 2 shape, and the reviewer's rv-mech1 mechanism
re-run as a proper test (scope now equals the full input document,
phaseCount 2, both dirs accepted).

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): fence-aware version/emoji half of preambleCutoff on the bracket branch (round-3 Major 1)

Gate-2 round-3 re-verify Major 1 (NEW): ff6bf0a8 (round-2 Blocker 3)
made the BRACKET half of preambleCutoff's "earliest milestone-shaped
heading" search fence-aware, but left the VERSION/emoji half a raw
`content.match` even on the bracket branch. A fenced VERSION-BEARING
example heading in a bracket repo's preamble (ADR-612's own docs
illustrate the LEGACY heading shape exactly this way, inside a fenced
authoring-guide block) was still textually the earliest match for that
raw regex, winning the min() and un-suppressing a wrong persisted 75%
that base correctly suppressed (rv-attack3c fixture C1: base
suppressed the percent entirely — `isMilestoneBounded` false — HEAD
wrote 75% where truth is 50%).

Fixed by deriving the version/emoji half from the SAME fence-aware
`currentMilestoneHeadings` token list as the bracket half, on the
bracket branch only — the exact `/^Phase\s+\S/i` / `/v\d+\.\d+|✅|📋|🚧/i`
pair `computeSectionEnd` already uses against `h.text`. The non-bracket
(legacy) path is untouched: it keeps the raw `content.match`, byte-
identical to before, including its own fence-blindness (repro12's
LEGACY control, pinned unchanged in the round-2 Blocker-3 test block —
not re-pinned here to avoid duplicating an already-covered assertion).

Not rated Blocker (per the review) because it is not a regression vs
round-1 and the fixture (a version-BEARING fenced example in a bracket
repo) is rarer than the already-fixed bracket-heading case; still
fixed now rather than disclosed, per this arc's own precedent (every
prior "disclose instead of fix" call in this PR has been overturned on
re-review).

Tests: new describe block "#612 PR-2 Major 1 round-3: preambleCutoff's
version/emoji half is fence-aware on the bracket branch" — RED-turned-
GREEN for case C1 (readTotal + syncedPercent, so the persisted 75% is
directly observed, not just the read-path total), PIN for case C2 (the
already-fixed fenced-bracket-heading shape, unchanged).

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* chore(#2761): correct changeset claims + mark runtime-gated BASE_SITES row (round-3 minors)

Gate-2 round-3 re-verify Minor 2: three changeset sentences in
.changeset/2761-bracket-read-tolerance.md were overstated in a new
direction after round-2:

- The split-milestone claim ("across a milestone split over two
  headings") was true only when the version-bearing heading came
  FIRST (repro8 case 1); false when it came LATER (round-3 Blocker 1
  case A). Now restated to say plainly "with the version-bearing
  heading in EITHER position" — true again now that round-3's Blocker
  1 fix lands earlier in this range.
- The "counted from the phases... rather than from every directory on
  disk" claim was false on cases A/B/D (a strict subset of the
  milestone's own phases). Restated as "ALL of the phases... not a
  subset", and extended to state that an unrelated bracket-shaped
  heading with no phase children of its own (case D's `[ADR.612]`
  shape) does not truncate the milestone either — true now, not before.
- "Each widened read is SELECTED by the project's phase_id_convention"
  was literally false for BRACKET_PHASE_TAIL_RE, which is RUNTIME-gated
  (via its only caller, isBracketMilestoneBoundary, itself only
  consulted when bracketBoundaryActive) rather than selector-gated.
  Restated behaviourally: "every widened read ENGAGES only when the
  project's resolved phase_id_convention is bracket" — true for both
  gating mechanisms, so it no longer implies a selector call this site
  does not make.

Minor 1: the STRUCTURAL IDENTITY test's BASE_SITES row for
BRACKET_PHASE_TAIL_RE (added in the B2 commit) asserts a property of
`phaseHeadingPrefixSrcFor` — the function — not of the call site; it
would pass unchanged even if the site were deleted. Safety at that
specific site rests entirely on a runtime gate the test cannot see.
Added `runtimeGated: true` to the row and threaded it into the
generated test's own title (`… [runtime-gated, not selector-covered]`),
so the gating mechanism is visible in test OUTPUT, not only in a source
comment that could drift silently.

No production code changed. Targeted suite green (48/48 in the
affected file); `node scripts/changeset/lint.cjs` ok; eslint clean.

* fix(#2761): harden round-3 preamble cutoff — subtree child scan + level cap

Team-lead review of f87bba0e found two edges in the round-3 preamble-
cutoff code, both hardened here.

AMENDMENT 1 — bracketHeadingHasMatchingChild (2e06aef5) checked only
`headings[index + 1]`, the IMMEDIATE next heading, not the candidate's
whole subtree. A genuine prior sibling milestone whose section opens
with a non-bracket subsection before its first phase heading
(`## [GSD.01] Setup` / `### Notes` / `### [GSD.01] 01: Old`) was
therefore wrongly rejected as a boundary — its real phase heading sits
TWO headings deep, not one — leaking its entire section into the
preamble unstripped.

CONFIRMED RED, not merely theoretical (built and ran the fixture
against f87bba0e before touching the fix, per instruction): scope
membership DOES drive the disk-side filter on this shape.
`GSD.01-01-old`'s directory was wrongly admitted into the CURRENT
milestone's filter via the leaked heading's qualified key
(`GSD.01-01`) — 3/2/67% where truth is 2/1/50%.

Fixed by scanning the candidate's full SUBTREE: continue past a
non-matching deeper heading instead of returning false on the first
one; only a same-or-shallower heading actually closes the subtree and
yields "no match found". A candidate whose entire subtree closes with
no same-id hit (including a genuinely childless one) still degrades to
`false` — over-inclusive, safe, unchanged from before.

AMENDMENT 2 — c483552a ported the version/emoji half of preambleCutoff
to the token-based scan with no level cap; the raw
`content.match(anyMilestonePattern)` it replaced was anchored
`^#{1,3}\s+`. A level-4+ version-bearing heading in the preamble
(`#### v2.0 notes`) therefore won the scan on the bracket branch where
the raw pattern — and the legacy path, unaffected — ignores it
outright. Fixed with `if (h.level > 3) continue;`, mirroring the
depth-sanity cap isBracketMilestoneBoundary already applies to the
bracket half of this same scan.

Tests: new describe block "#612 PR-2 round-3 hardening: subtree child
scan + level cap on preambleCutoff" —
- RED-turned-GREEN for the Notes-intervening fixture: exact 2/1/50 (was
  3/2/67), plus the disk-filter observable (`GSD.01-01-old` now
  correctly excluded).
- PIN for the level-4 preamble heading: the scope now PRESERVES the
  heading's text (was silently dropped before this fix — harmless in
  this minimal fixture's total_phases specifically, since the dropped
  text carries no phase-shaped content, but a real correctness gap
  against the raw pattern's own ceiling) — asserted via scope content,
  not total_phases, since that number is invariant here either way.
- PIN for the LEGACY control on the same level-4 shape — unchanged,
  confirming the raw content.match path is untouched.

Re-verified the existing genuine-prior-sibling and childless-sibling
pins (round-3 Blocker 1 commit) still pass under the subtree scan —
both fixtures' outcomes are unchanged since their same-id hit (or its
absence) was already at the first deeper heading.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 942/942 pass (939 + 3 new). node scripts/lint-phase-id-drift.cjs

lint:ci` deferred to the team lead's own run per instruction.

* fix(#2761): bracketHeadingHasMatchingChild requires a same-id PHASE child (round-4 Blocker 1)

Gate-2 round-4 re-verify Blocker 1 (NEW): the round-3 hardening's
subtree scan (fbfd0fca) proved SAME-ID-NESS but never asked whether
the matching child was PHASE-shaped. Case F1 re-opens round-3's case D
one heading later: `## [ADR.612] Heading convention` is followed by
its OWN sub-heading `### [ADR.612] Examples` — same bracket id as the
candidate, but MILESTONE-shaped (a name, no digit-then-colon), not a
phase. Same-id-ness alone satisfied the subtree scan and re-cut the
preamble at exactly the shape the round-3 hardening was written to
close.

Failing input: `## [ADR.612] Heading convention` / `### [ADR.612]
Examples` (prose) / `### [GSD.02] 01: One` (the current milestone's
own first phase, now unreachable) / `## [GSD.02] v2.0: Foundation` /
`### [GSD.02] 02: Two`. Truth 2/1/50. HEAD read 1/0/0, and `state sync`
reported "nothing to do" (exit 0, `{synced:true,changes:[]}`) because
its wrong 0% happened to equal the STATE.md seed — a half-done
milestone read as untouched with no write-path signal at all.

Fixed with the reviewer's one-conjunct addition: a same-id child only
counts if it is ALSO phase-tail-shaped (`BRACKET_PHASE_TAIL_RE`) — the
same single-owner discriminator `isBracketMilestoneBoundary` already
uses one level up for the identical distinction (phase vs milestone),
reused here rather than re-derived. This is exactly what the
changeset's own wording already claimed ("no phase children of its
own") — the code now matches the sentence rather than the other way
around.

Docstring updated at the function itself: the rule is "same-id PHASE
child", not "same-id child".

Tests: new describe block "#612 PR-2 round-4 Blocker 1: the same-id
child must be PHASE-shaped" — RED-turned-GREEN for F1 with
syncedTotal()/syncedPercent() (the persisted 0% — and the
report-nothing-to-do write-path silence — is the point), PINs for F11
(colon-less same-id child) and F11b (bullet-only phase list): both
correctly stay excluded either way, and the leak the phase-shape
requirement newly creates for these two shapes is INERT — a colon-less
heading forms no qualified key (getMilestonePhaseFilter's own
phase-heading pattern requires the colon too) and a bracket bullet
never matches the legacy-only BULLET_PHASE_LINE_PATTERN — confirmed
directly via getMilestonePhaseFilter, not merely inferred. Re-verified
the four existing child-rule pins (F2 subtree-closure, F3 deep-nested
same-id, F4 level-4 same-id, F5 childless-at-EOF) are unaffected by the
phase-shape requirement, since every one of them already used a
colon-bearing same-id child.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): fence-aware phase counting, milestone bounding, and bracket-fallback selection (round-4 Major 1)

Gate-2 round-4 re-verify Major 1 (NEW): roadmapPhaseCount is a
fence-blind raw `.exec()` over the scope string, duplicated in TWO
independent copies (buildStateFrontmatter's read path, cmdStateSync's
write path). With the bracket alternative now compiled into it (#612),
a fenced EXAMPLE phase heading in the preamble inflates total_phases
and persists a wrong percent that base got right. Two further
fence-blind sites participate: isMilestoneBounded (a raw
`.test(roadmapRaw)`) and the bracket-fallback SELECTOR inside
extractCurrentMilestone (a raw `content.matchAll`, only reachable when
version-string selection finds nothing).

Failing inputs:
- F10 (clean isolate, version-bearing selection): a fenced
  `### [GSD.02] 05: Example phase` in the preamble inflates
  total_phases 2->3, persisting 33% where truth is 50%. LEGACY control
  on the same shape is correct on every build — not a pre-existing
  hazard being inherited, bracket-only.
- F9 (version-less selection): a fenced example carrying the project's
  OWN milestone id additionally confuses the bracket-fallback selector
  (the fenced heading gets SELECTED), compounding with the same
  fence-blind counter. base suppressed the percent; round-1 and HEAD
  both wrote 33%.
- F12 (isMilestoneBounded isolate): the ONLY `[GSD.02]` heading in the
  document is inside a fence, and the asserted milestone genuinely has
  no section at all — HEAD persisted 67% where base correctly
  suppressed the percent (the milestone is absent from the roadmap).

Fixed at the CONSUMER level, not the producer — extractCurrentMilestone's
returned scope string is deliberately UNCHANGED, since every other
consumer of that string needs its full content fidelity and legacy
identity forbids touching the shared string (this branch's own
precedent, ff6bf0a8/c483552a, was producer-level; here the ruling is
consumer-level because the string is shared far more broadly than the
two round-3 fixes' narrower producer edits):

(a) New `countRoadmapPhaseHeadings` (src/state.cts, immediately above
    extractRetiredPhaseNumbers) — ONE shared implementation for both
    call sites, replacing two independently-maintained copies. BRACKET
    convention counts via `tokenizeHeadings(scope)` at levels 2-4,
    testing each heading's hash-stripped text directly — fence-aware by
    construction, since tokenizeHeadings never produces a token for a
    fenced line. LEGACY convention keeps the exact pre-existing raw
    `.exec()` loop, byte-for-byte. A pre-existing, deliberately
    PRESERVED asymmetry between the two original call sites — the read
    path always excluded a bare `/^999\b/` token, the write path never
    did — is threaded through as an explicit
    `includeUnconditional999Check` parameter per call site, so sharing
    the implementation does not silently unify (and thereby move)
    either total.
(b) isMilestoneBounded's bracket branch now scans
    `tokenizeHeadings(roadmapRaw)` for a matching heading (level <= 3)
    instead of a raw regex test. Legacy version-string branch untouched.
(c) The bracket-fallback SELECTOR now builds its candidate set from
    `tokenizeHeadings(content)` instead of `content.matchAll`,
    reconstructing a match-shaped array so every downstream consumer of
    `headingMatches` sees the identical shape the raw-regex path always
    produced. This is the ONE site in this entire arc where SELECTION
    itself changes — selection SEMANTICS are otherwise unchanged (same
    pattern, same first-match-wins by document order); only the
    candidate set is now fence-aware. Pinned that unfenced selection is
    byte-identical.

Zero drift measured across the full historical corpus (repro2-13,
rv-attack1/1b/3c, rv-mech1, rv2-amend1/2, and F1-F11b) except the three
target fixtures.

Tests: new describe block "#612 PR-2 round-4 Major 1: four fence-blind
sites on the bracket path" — RED-turned-GREEN for F10 (with
syncedTotal()/syncedPercent()) and F9 (both layers), PINs for F10's
LEGACY control and F10c (non-phase-shaped fence, unaffected either

* chore(#2761): correct docstring overstatement + stale consumer-count sentence (round-4 minors)

Gate-2 round-4 re-verify Minor 1 + Nit 1. No production code changed.

Minor 1: bracketHeadingHasMatchingChild's own docstring said a
rejected (no-same-id-PHASE-child) candidate's degrade "contributes
nothing to any phase count" — true of the candidate's OWN heading
text, but not of its SUBTREE, which is what actually stays in the
preamble. F7 (`## [GSD.01] Setup` / `### [GSD.07] 01: Foreign`) shows
a DIFFERENT-id bracket PHASE heading inside a rejected candidate's
subtree DOES form a qualified key and CAN admit a foreign directory —
3/2/67%, stable across base, round-1 and HEAD (base via its own
pass-all degrade). Not a regression, still the declared over-inclusive
/ never-under-inclusive safe direction — the comment now says that,
with F7's numbers cited, at the call site that actually decides
`isBoundary` (roadmap-parser.cts's preambleCutoff loop) rather than
only at the helper's own definition.

Minor 2 (changeset) — VERIFIED, no wording change needed: re-ran F1,
F9, F10, F12 at this HEAD. The "no phase children of its own... does
not truncate it either" sentence (naming the `[ADR.612]` shape
directly) is now literally true — F1 reads 2/1/50. The "counted from
ALL of the phases... not a subset" sentence is now true on every
measured shape — F1/F9/F10 all read 2/1/50, F12 correctly suppresses
the percent. No carve-out for F9/F10 is needed since round-4 Major 1
(3be5c412) closes both; per the fix-round instruction to "only carve
out anything genuinely left," nothing is.

Nit 1: tests/adr-612-bracket-heading-selection.test.cjs's runtimeGated
row claimed `BRACKET_HEADING_INTRO_RE` has "no other consumers" — true
when round-3's f87bba0e wrote it, stale since 2e06aef5 (round-3's own
earlier commit) had already added two more uses inside
bracketHeadingHasMatchingChild. Corrected to state the true count
(three consumers) and re-confirm the conclusion is unaffected: all
three are still nested inside the same bracketBoundaryActive runtime
gate, and BRACKET_HEADING_INTRO_RE is built from BRACKET_ID_SRC, not
phaseHeadingPrefixSrcFor, so it was never a selector site regardless of
consumer count.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): restore the bracketId guard in countRoadmapPhaseHeadings (round-5 Blocker 1)

Gate-2 round-5 re-verify Blocker 1 (NEW, introduced by 3be5c412): the
merge that created the shared countRoadmapPhaseHeadings helper dropped
the `bracketId && ` guard both original inline loops carried before
calling isSentinelPhaseId. Every other isSentinelPhaseId call site in
src/ (roadmap-parser.cts, roadmap.cts, validate.cts x2, verify.cts)
keeps the guard; state.cts's shared counter was the only one of seven
without it.

When the phase-heading-intro grammar's LEGACY alternative matches (a
`### Phase 00:` heading in a `phase_id_convention: "bracket"` repo —
the mid-migration shape this PR exists for), the bracket capture group
is `undefined`, so the unguarded call became
`isSentinelPhaseId("undefined-00", 'bracket')` — measured TRUE, so
phase 00 (and 000, 0a, 0.5, 999.1 — any token whose splice with the
literal string "undefined" happens to fall in a sentinel range) was
silently dropped from the denominator. `getMilestonePhaseFilter` (which
still carries its own guard) counts the phase and admits its directory
regardless, so the filter and the counter disagree — a half-done
milestone reads as 100% complete, persisted.

One-line fix, restoring the guard every sibling call site already has:

    if (bracketId && isSentinelPhaseId(`${bracketId}-${token}`, 'bracket')) continue;

Line count: `git diff --stat src/state.cts` -> 1 file changed, 1
insertion(+), 1 deletion(-).

Tests: new describe block "#612 PR-2 round-5 Blocker 1:
countRoadmapPhaseHeadings restores the bracketId guard" — RED-turned-
GREEN for G3 (3/2/67, was 2/2/100) and G3d (the mixed bracket+legacy
mid-migration shape, same numbers) with syncedTotal()/syncedPercent(),
PIN for G3's legacy control (unaffected), PIN for G3b (isolates the
counter with no directory to admit), PIN for G3c (legacy 01/02 only,
no sentinel-shaped token present).

* fix(#2761): extractRetiredPhaseNumbers is fence-aware on the bracket path (round-5 Major 1)

Gate-2 round-5 re-verify Major 1 (NEW) — a FIFTH fence-blind site on
the bracket path, missed by 3be5c412's own enumeration of "four".
extractRetiredPhaseNumbers' line scan (`scope.split(/\r?\n/)`) has no
fence awareness. This PR compiles the bracket alternative into
`introSrc` ("the retirement filter has to widen with the counter it
protects" — the function's own pre-existing comment), so a FENCED
authoring EXAMPLE showing the #1514 retirement gesture in bracket
spelling is now indistinguishable from a real one: it retires a
genuine phase, shrinking the denominator and persisting a confident
100% where base correctly read 50%.

Fixed with the SAME consumer-level ruling this arc has used at every
other fence-blind site, reusing markdown-sectionizer's existing
exported `stripFencedCode` rather than hand-rolling a second fence
parser (single-owner rule) — retirement lines are BULLETS, not
headings, so `tokenizeHeadings` doesn't serve here; `stripFencedCode`
is the general-purpose fence stripper the tokenizer itself is built on.
Gated on `convention === 'bracket'`; the LEGACY line scan stays the raw
`scope` string, byte-identical — its own fenced-example hazard is
pre-existing (wrong at base too) and out of scope.

Line count: `git diff --stat src/state.cts` -> 1 file changed, 9
insertions(+), 2 deletions(-) — one import added, four lines inside
the function (a comment + the `scanScope` computation + the changed
`.split()` call).

Tests: new describe block "#612 PR-2 round-5 Major 1:
extractRetiredPhaseNumbers is fence-aware on the bracket path" —
RED-turned-GREEN for G2 (fenced example in the preamble) and G2b (the
same example placed INSIDE the milestone section, ruling out a
preamble-scoping artifact — the site itself was fence-blind wherever
the fence sits), PIN for the LEGACY control (unchanged, pre-existing,
out of scope — base is wrong on this shape too).

Also folds in the "four fence-blind sites" correction: 3be5c412's
commit message and any restatement of it should read FIVE going
forward; this commit's own message states the count correctly.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): state sync's counter excludes the bracket 999 icebox token (round-5 Major 2)

Gate-2 round-5 re-verify Major 2 (NEW) — `includeUnconditional999Check`
left `state json` and `state sync` reporting different totals for one
bracket repo. Under bracket, READING-B puts the sentinel in the
bracket, so `isSentinelPhaseId("GSD.02-999", 'bracket')` is false —
the `/^999\b/` TOKEN rule is the only thing excluding a
`### [GSD.02] 999:` icebox heading, and it ran on the read path
(buildStateFrontmatter, `true`) and on getMilestonePhaseFilter
(unconditional), but not on cmdStateSync's own counter (`false`). One
`state sync` call could leave a single STATE.md with its own
frontmatter (percent 50, from the read-path re-sync inside
writeStateMd) and body (percent 33, from the write-path counter that
alone still counted the icebox heading) disagreeing — falsifying this
PR's own stated invariant that sharing countRoadmapPhaseHeadings made
"the two counters must see the same phases" structural.

Functional change is one argument, exactly as specified: the write
call site now passes `syncConvention === 'bracket'` instead of the
literal `false`. `syncConvention === 'bracket'` is `false` for every
non-bracket value, so the LEGACY path resolves to the exact same
`false` it always did — this file's own pre-existing, deliberately-
unchanged read/write divergence on that path is untouched. The READ
site (`:1860`) is NOT touched — its historical behaviour applied
`/^999\b/` to legacy and bracket alike, so changing it would move
legacy READ totals, exactly the class of mistake this arc's own
Blocker 1 (this round) was.

Line count: the functional change is ONE argument
(`false` -> `syncConvention === 'bracket'`); the surrounding comment
was rewritten because the previous one asserted the now-superseded
behaviour ("preserving this file's pre-existing... divergence... a
bare 999 token is not excluded here") and leaving it would mislead the
next reader — not a structural change.

Tests: new describe block "#612 PR-2 round-5 Major 2: state sync
excludes the bracket 999 icebox token like the read path" —
RED-turned-GREEN for G1, asserting `state sync`'s body percent equals
`state json`'s own percent (both 50, not 33 vs 50), PIN for G1's
legacy control (33 vs 50 unchanged, deliberately).

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* chore(#2761): restore indent parity at the two line-start-anchored bracket-heading reconstructions (round-5 Minor 1)

`HeadingToken.offset` (tokenizeHeadings) is the LINE-START character offset,
not necessarily the `#` character's own offset — a ≤3-space-indented ATX
heading has both. Two round-4 reconstructions built on tokenizeHeadings
inherited this gap and accepted indented headings their raw, line-start-
anchored predecessors (`^#{1,3}\s+\[...`) never matched:

  1. roadmap-parser.cts's bracket-fallback SELECTOR (extractCurrentMilestone,
     ~line 377) — an indented, version-less `[GSD.02]` milestone heading
     could be reconstructed into headingMatches, then mis-parsed downstream
     (selectedBracketId null, level fallback to 1), leaking a SIBLING
     milestone's phases into the counted scope (G6: HEAD read 3/2/67 instead
     of 2/1/50 — a real phase heading's own directory belonging to the NEXT
     milestone got counted).

  2. state.cts's isMilestoneBounded (~line 1571) — the same gap let an
     indented-only `[GSD.02]`-shaped heading wrongly bound a milestone
     absent from the roadmap, un-suppressing a percent that should stay
     suppressed (mirrors round-4's F12 fenced-only case, but via indentation
     instead of a fence).

Fix: one added conjunct per site — `content[h.offset] === '#'` (source-named
`roadmapRaw` in state.cts) — filtering to tokens whose LINE-START offset IS
the `#` character, i.e. exactly the set the raw line-start-anchored regex
would ever have matched. Restores byte-for-byte raw parity; no other logic
in either function changes. computeSectionEnd and the preamble version/
emoji-token scan are untouched, as instructed — they consumed tokenizeHeadings
output before this arc and are out of scope here.

Also corrects roadmap-parser.cts's now-provably-false docstring claim that
`h.offset` is unconditionally "the same `#`-character coordinate space
`content.match().index` used" — true only for the survivors of the new
filter, not for every token tokenizeHeadings produces.

Line count: the FUNCTIONAL change is exactly 2 lines (one added `&&` conjunct
per call site — `git diff --stat` on the two source files shows 20
insertions/7 deletions, but only those 2 lines change behavior; the rest is
docstring/comment rationale, per this round's "state the line count" ask).

TDD: both fixtures verified RED at HEAD before this commit, GREEN after,
via /tmp/pr612rev/rv5-attack.cjs G6 and a locally-authored isMilestoneBounded-
isolating probe (G6 alone doesn't distinguish the two sites — its unindented
phase headings already satisfy isMilestoneBounded's loose prefix regex
either way, so a second, indentation-only fixture was needed to prove that
site's fix is not a no-op; verified by temporarily reverting just that one
conjunct, confirming 100%-wrongly-bounded RED, then restoring it, confirming
suppressed-percent GREEN).

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (G6): indented version-less bracket milestone heading — 2/1/50, not
    the pinned-before-fix 3/2/67.
  - PIN (G6c unindented control): identical document, no indent — 2/1/50
    unaffected on every build.
  - RED (isMilestoneBounded site, indented-ONLY): mirrors round-4's F12
    shape (fenced-ONLY → indented-ONLY) — percent stays suppressed instead
    of the pinned-before-fix wrongly-bounded 100%.

Full G1-G10 (rv5-attack.cjs) + G2b/G3c/G3d/G6c (rv5b.cjs) re-verified
zero-drift against TRUTH after this change. Targeted suite (adr-612-*,
roadmap-parser, state, verify): 962 -> 965 (+3), 0 fail.

* chore(#2761): changeset discloses counting-set narrowing + correct stale consumer-count sentence (round-5 minors)

FIX 5 (Minor 2): .changeset/2761-bracket-read-tolerance.md did not disclose
that bracket phase-heading counting is narrower than the raw-regex
predecessor in two ways the review's G4/G5 fixtures surfaced: a level-5
heading (`##### [GSD.02] 05: ...`) is no longer counted (the counter's
tokenizeHeadings scan caps at level 4, matching the selector/isMilestoneBounded
ceiling), and a space-less heading (`###[GSD.02] 05: ...`) is no longer
counted (CommonMark requires ≥1 space/tab after the hashes, which
tokenizeHeadings correctly enforces and the old raw regex did not). Both
G4 and G5 moved from round-1's wrong (inflated) values back to base's
original values as an incidental side effect of routing through
tokenizeHeadings — never a deliberate feature of this PR, and previously
undocumented. One clause added to the existing run-on paragraph; no other
wording in the changeset touched.

FIX 6 (Nit 1): tests/adr-612-bracket-heading-selection.test.cjs:76 —
`BRACKET_PHASE_TAIL_RE` has TWO consumers as of round-4's 65d257ce
(isBracketMilestoneBoundary's own use, plus bracketHeadingHasMatchingChild's
same-id-PHASE-child conjunct), not the "no other consumers" the comment
claimed. Same correction pattern round-4 already applied to this row's
BRACKET_HEADING_INTRO_RE neighbor (that sentence's own staleness was fixed
in 4d7184b8): note the true consumer count, confirm both stay nested inside
the same bracketBoundaryActive runtime gate (verified at
src/roadmap-parser.cts:178 and :250, both reached only through the
`if (bracketBoundaryActive)` block starting at :529), and record which
commit and which fix introduced the drift. Comment-only; no assertion
logic changed.

Line count: 2 files, 8 insertions / 2 deletions total — one added clause
in the changeset (1 line changed) and one comment block replacing the
single stale line in the test file (6 comment lines replacing 1).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 965/965 pass (comment/prose-only diffs, no test count change).
`node scripts/changeset/lint.cjs` and `npx eslint` on the touched files both
clean.

* fix(#2761): restore the bracketId guard on the bracket-only /^0\b/ sibling rule (round-6 Blocker 1)

Round-5's Blocker 1 was `isSentinelPhaseId("undefined-00")` — the merge
that introduced the shared counter dropped the `bracketId &&` guard on the
sentinel check. This is the identical failure one line further down, in the
sibling rule this PR itself added: when the phase-heading grammar's LEGACY
alternative matches (`### Phase 0:` in a `phase_id_convention: "bracket"`
repo — the mid-migration shape this PR exists for), `bracketId` is
`undefined`, and the unguarded `/^0\b/` fires on the bare token anyway.
Neither the LEGACY branch of this same function nor
`getMilestonePhaseFilter` has a `/^0\b/` rule at all, so the filter counts
the phase and admits its completed directory while the counter refuses to
count its heading — a milestone with an unstarted phase 02 persists as a
confident 100%.

`/^0\b/` matches `0` and `0.5` (word boundary before the `.`) but not `00`
(no boundary between the two zeros), which is exactly why round-5's G3/G3d
fixtures (`### Phase 00:`) never tripped this one — same defect class,
different token spelling.

Fix: one word, mirroring the guard round 5 restored two lines above —
`if (/^0\b/.test(token)) continue;` -> `if (bracketId && /^0\b/.test(token)) continue;`.

Expected and intentional side effect: `roadmap analyze` and `state json`
now disagree again on this bracket-repo shape (analyze phase_count=2, json
total_phases=3) — exactly as they already do under the legacy convention
today (verified via /tmp/pr612rev/rv6c.cjs on both conventions). That is
the counter regaining agreement with `getMilestonePhaseFilter` (the tighter
constraint — it is what actually decides `completed_phases`), not a new
break; the counter/filter disagreement is what was wrong.

Out of scope, deliberately NOT fixed here (Minor 1, disclosed via a PIN
test only): the bracket-SPELLED `### [GSD.02] 0:` shape has the same
counter/filter disagreement, but reads 2/2/100 on base too — never closed
by any build in this arc, so it is a pre-existing gap rather than a
regression this commit could introduce.

Line count: src/state.cts is exactly 1 insertion / 1 deletion (one word,
`bracketId && ` prepended to the existing condition).

TDD: T0 (`Phase 0:`) and T05 (`Phase 0.5:`) verified RED at HEAD before this
commit (json 2/2/100, sync body 100%) via /tmp/pr612rev/rv6b.cjs, GREEN
after (3/2/67 on both derivations, matching TRUTH). Zero-drift verified by
diffing the FULL corpus (rv5-attack, rv5b, rv4-attack, rv-attack1,
rv-attack1b, rv-attack3c, rv-mech1, rv2-amend1, rv2-amend2, rv6-attack
H1-H19, rv6b) between a pre-fix and post-fix build: the only differing
lines in the entire diff are T0, T05, and H14 — the three target fixtures.

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (T0) + PIN (T0L legacy control)
  - RED (T05) + PIN (T05L legacy control)
  - PIN (B0, bracket-spelled `0` — base-parity characterization, Minor 1,
    not fixed this round)
  Round-5's own G3 test (`### Phase 00:`) already serves as the T00 pin —
  `/^0\b/` never matched `00`, so it is unaffected and untouched.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 965 -> 970 (+5),
0 fail. `lint-phase-id-drift.cjs` and `npx eslint` on touched files clean.

* chore(#2761): changeset re-attributes the phase-count level cap + discloses the bare-0 carve-out; correct two stale test comments (round-6 Minor 1 + Nits)

FIX 2 (Minor 1 — disclosure only, NOT a code fix): the bracket-SPELLED
`### [GSD.02] 0:` / `0.5:` shape has the same counter/filter disagreement
round-6's Blocker fixed for the legacy spelling, but it reads 2/2/100 on
BASE too — never closed by any build in this arc, so it is a pre-existing
gap rather than a regression this round could introduce. Two changes:

  - Pinned as a base-parity characterization: new PIN test (B0) in
    04b5a95f's describe block asserting the exact unchanged value with a
    comment stating why it's deliberately not touched.
  - .changeset/2761-bracket-read-tolerance.md: one qualifying clause added
    to the "counted from ALL of the phases … not a subset" sentence — a
    bare `0`/`0.x` phase token (however spelled) keeps `roadmap analyze`'s
    own pre-existing sentinel reading under bracket too, so it stays
    excluded from these counts. Carried over, not newly introduced by this
    PR — `roadmap analyze` has always read it this way.

FIX 3(a) — same changeset paragraph misattributed the phase counter's
2-4 level cap to "the milestone-boundary machinery in this PR" (the
selector, `isMilestoneBounded`, the preamble scan) — that machinery caps
at `###` (level ≤3), not 2-4. The 2-4 cap belongs to
`getMilestonePhaseFilter`'s own phase scan. Re-pointed the attribution;
the paragraph's earlier, correct ≤3 claim (selector/isMilestoneBounded)
is untouched.

FIX 3(b) — tests/adr-612-bracket-heading-selection.test.cjs:76-82 (added by
1395bd89, round-5's own Nit-1 correction) claimed both
`BRACKET_PHASE_TAIL_RE` consumers are reached "only through the
`if (bracketBoundaryActive)` block starting at :529". Verified at HEAD:
`bracketHeadingHasMatchingChild` is (only caller :593, inside that block).
`isBracketMilestoneBoundary` is not — it has two callers, an inline
`bracketBoundaryActive &&` conjunct at `:473` (inside `computeSectionEnd`)
and the `:529` block at `:567` — the very fact this row's own earlier
"exactly two callers" paragraph already stated correctly. Corrected the
mechanism claim; the CONCLUSION (every consumer is still gated on the same
flag) is unchanged, exactly as round-5's own Nit-1 fix left round-4's
conclusion unchanged when it corrected the consumer count.

FIX 3(c) — tests/adr-612-bracket-phase-counting.test.cjs:2311,2340 still
said "four fence-blind sites" after round-5 (357ba671) added a fifth
(the retirement scan) in its own block below. Reworded both the section
comment and the `describe()` label to read as historical scoping of
round-4's own fix ("the four sites known at round 4 … a fifth was found at
round 5, see its own block below") rather than a live exhaustive claim.

Line count: 3 files, changeset 1/1, heading-selection test 17/8,
phase-counting test 6/2 (comment/prose-only; B0's own PIN test landed in
04b5a95f alongside T0/T05 since it was investigated as part of that same
Blocker's defect class, not in this commit — noted here for the record).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 970/970 (comment/prose-only diffs, no test count change).
`npx eslint` and `node scripts/changeset/lint.cjs` both clean.

* fix(#2761): W021's bracket remediation hint stops pointing at a command that hard-errors (round-7 Minor 2)

`checkBracketCoherence`'s W021 (added by 94abf5df) attached the fix hint
`Run \`gsd-tools roadmap upgrade --convention bracket\` to migrate
(dry-run by default)` to every bracket-convention W021 — both sub-checks
(`missing-bracket` and `mismatch`) share the single `addIssue` call at
src/verify.cts:2255-2256. But `roadmap-command-router.cts:204` throws
unconditionally for any `--convention` value other than
`milestone-prefixed`:

  $ gsd-tools roadmap upgrade --convention bracket
  Error: Only --convention milestone-prefixed is supported

This contradicts the PR's own two disclosures: the changeset ("`bracket`
is a READ-path opt-in until the migrator and write path land") and
docs/CONFIGURATION.md:188 ("There is no bracket migrator and no bracket
emit yet"). Reachability is the exact mid-migration repo this PR targets —
any bracket project with one un-migrated heading gets an unfollowable
instruction on every `validate health`.

Fix: one string. Replaced the hint with what a user can actually do today —
manually align the heading's bracket milestone to its section — and named
the tracked future landing (#612 PR-3) instead of a command that errors.
The milestone-prefixed sibling hint at src/verify.cts:2240 (a different,
already-functional convention/command pair — verified against
roadmap-command-router.cts:65) is untouched.

Line count: src/verify.cts is exactly 1 insertion / 1 deletion (one string
literal).

No test in the suite previously asserted this string's content
(`grep -rn "upgrade --convention bracket" tests/` was empty), so the
unfollowable hint shipped unpinned — `lint-fix-has-regression-test.cjs`
would not have caught a string-only change without a new test. Added one:
asserts the fix string both (a) does not match `--convention bracket`
(the specific pinned-before-this-fix hazard) and (b) equals the new string
exactly, covering the invariant a future edit must not re-break: no
unsupported `--convention` value named in remediation text users are
expected to run verbatim.

Verified end-to-end (not just unit-level) via /tmp/pr612rev/rv7f.cjs: the
W021 issue's `fix` field now reads the new string; `gsd-tools roadmap
upgrade --convention bracket` (and its --dry-run variant) still correctly
hard-error — that command remains unsupported, only the hint text changed.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 970 -> 971 (+1),
0 fail. `lint-phase-id-drift.cjs` clean; `npx eslint` on touched files:
0 errors (1 pre-existing unrelated no-elapsed-assertion warning, same file,
same line this arc's prior rounds already disclosed).

* chore(#2761): correct the bare-0 changeset disclosure + disclose W021's second sub-check (round-7 Minor 1 + Nit 1)

FIX 1 (Minor 1) — round-6's bare-0 changeset clause (1395bd89) was wrong in
three falsifiable ways:

  (a) Its own illustration (`### Phase 0:`) is exactly the LEGACY spelling
      04b5a95f made COUNTED. The residual exclusion after that fix applies
      only to the BRACKET-spelled token (`### [GSD.02] 0:`) — the clause
      named the wrong shape as its example.
  (b) "excluded from these counts" over-scoped the carve-out. The phase-0
      directory is admitted into `completed_phases`/`total_plans` in BOTH
      spellings (measured: B0 at HEAD has `completed_phases=2`,
      `accepts {"GSD.02-0-bootstrap":true}`). The exclusion that survives
      lives in `total_phases`/`phase_count` (heading counting) only.
  (c) The pre-existing "so `roadmap analyze` and `state json` report the
      same number" sentence (present since before this arc's bracket work)
      is now false for the bare-0 LEGACY-spelled shape: 04b5a95f's own
      commit message discloses this exact re-divergence as expected —
      `roadmap analyze` phase_count=2 vs `state json` total_phases=3 on T0
      — matching the disagreement legacy already carries today. The
      changeset still asserted unconditional agreement.

Rewrote both sentences: dropped the `### Phase 0:` example, scoped the
carve-out to `total_phases`/`phase_count`, named the bracket-spelled token
as the one that keeps analyze's sentinel reading, stated plainly that the
legacy-spelled form in a bracket repo IS counted (the mid-migration guard),
and qualified the "report the same number" claim to the `999` token, with
the bare-0 legacy-spelled shape named as the one exception and why.

FIX 3 (Nit 1) — `checkBracketCoherence` has always had two sub-checks
(its own docstring: "Two sub-checks, both surfaced as W021") but both the
changeset and docs/CONFIGURATION.md:188 described only the `mismatch`
sub-check. The `missing-bracket` sub-check — which fires on every
legacy-spelled heading in a bracket repo, the noisier of the two on a
mid-migration project — was undisclosed in both places. One clause added
to each.

Line count: 2 files, 1 line changed each (both are single-paragraph/
single-row files; git diff --stat reports 1/1 per file though several
distinct clauses were edited within that one line each).

Verified: `node scripts/changeset/lint.cjs` clean. Targeted suite
(adr-612-*, roadmap-parser, state, verify) unchanged at 971/971
(prose-only diffs, no test count change, no code touched).

* chore(#2761): resolvePhaseIdConvention's docstring no longer claims loadConfig drops the key

Upstream #2997 (aa7697fe, landed in `next` during this PR's final
verification) added `phase_id_convention: get('phase_id_convention') ?? null`
to `_baseConfig` in config-loader.cts — `loadConfig` now surfaces
`phase_id_convention` in its resolved config. This function's docstring
gave "loadConfig merges against CONFIG_DEFAULTS and drops keys it does not
know, and `phase_id_convention` is not among them" as the reason for
reading config.json directly instead of calling `loadConfig(cwd)`. That
rationale is now stale against live `next`.

Corrected the comment to state the two reasons that actually survive #2997:

  1. The workstream->root federation this function performs is a standalone
     resolution run against a GIVEN cwd, not necessarily the same base a
     `loadConfig(cwd)` call elsewhere in the codebase would federate from.
  2. Convention-ENUM validation is still #612 PR-4 work — this function
     returns the raw string unvalidated, exactly as the now-surfaced
     resolved key would.

Noted that #2997 surfacing the key makes consuming it from resolved config
(instead of re-reading config.json here) a natural PR-4 consolidation —
not this PR's scope. The "cycles were never the obstacle" close and every
other paragraph in the docstring (federation rationale, SCOPE note) are
untouched; they still hold.

Comment-only — no code behavior changed. This worktree's own history does
not contain aa7697fe (git merge-base --is-ancestor confirms neither branch
is an ancestor of the other; not rebasing per instruction), so this is a
textual correction against a documented external fact, not a functional
sync with upstream.

* fix(#2761): resolve phase_id_convention against the caller's workstream

`resolvePhaseIdConvention` took no workstream, so it resolved from
`planningDir(cwd)` — which falls back to `GSD_WORKSTREAM` only when its `ws`
argument is `undefined`. Every caller that passes a workstream by ARGUMENT
(they cannot set the env var per iteration) therefore read the convention from
the ROOT config while reading that workstream's ROADMAP.

Two reproduced consequences:

- A workstream that explicitly declares its own `phase_id_convention` had it
  ignored. Flipping ONLY the root config between bracket and milestone-prefixed
  changed which milestone that workstream extracted.
- `--workstream foo` and `GSD_WORKSTREAM=foo` disagreed on the same repo: the
  arg form fell through to the root config, the env form did not.

`resolvePhaseIdConvention(cwd, ws?)` now forwards `ws` to `planningDir`, and
both roadmap-parser call sites pass theirs — `extractCurrentMilestoneScoped`
(which already reads STATE from `planningDir(cwd, ws)`) and
`getMilestonePhaseFilter`'s lazy branch. `undefined` keeps the env fallback, so
convention-less call sites are byte-identical; `null` still means "explicitly no
workstream". The `undefined` vs `null` discriminator on `phaseIdConvention` is
untouched — only the base the `undefined` branch resolves FROM moves.

workstream-inventory's two sites (`countRoadmapPhases`, `inspectWorkstream`)
passed a literal `null` where they meant `undefined`, pinning every workstream
to the legacy grammar. On a bracket workstream whose milestone declares 3
phases that returned phaseCount 0 and fell back to the on-disk directory count;
it now returns 3. A non-bracket workstream is unchanged (legacy control pinned).

The workstream -> root federation is preserved: a workstream that declares no
convention still inherits the root, as config-loader does. That inheritance is
pinned so the fix cannot be over-applied into isolation.

* fix(#2761): classify missing phase details per occurrence, not per token

Under READING-B a phase's sentinel status lives in the BRACKET, so
`[GSD.999] 01` and `[GSD.02] 01` share a token and are not the same phase.
Both sides of the missing-detail check were keyed by the bare token anyway, and
both produced false negatives in `missing_phase_details`:

- The checklist scan built a token -> bracket-id Map, FIRST-WINS. Of two entries
  sharing a token, whichever the author wrote first classified both. With
  `- [ ] **[GSD.999] 01: Icebox**` above `- [ ] **[GSD.02] 01: ...**` the real
  phase inherited the icebox's sentinel verdict and vanished from the report;
  swapping the two bullets — same document, same phases — reported it. Pinned
  with a test asserting BOTH orders.

- The detail set was `new Set(phases.map(p => p.number))`, also token-keyed, so
  `[GSD.02] 01`'s heading marked token `01` present and satisfied
  `[GSD.03] 01`, which has no heading anywhere. Order-independent, same class.

Both sides now key on an occurrence key: the owner's `bracketQualifiedKey`
(fold- and padding-insensitive, so `[gsd.2] 01` and `[GSD.02] 01` are one
phase), falling back to a fold-normalized composite for the two shapes that
grammar refuses — a token carrying its own hyphen, which splices to an id whose
trailing segment the qualified-key grammar truncates (the hazard
`getMilestonePhaseFilter` guards with its own `!token.includes('-')`), and any
id it does not accept. With no bracket id the key IS the bare token, so the
legacy path keeps its exact keys and dedupe order.

The emitted value is unchanged — `missing_phase_details` stays an array of bare
tokens, matching `phases[].number`. Only the classification moved to the
qualified key, so two brackets' `01` both missing report `01` once instead of
one silently covering for the other.

* test(#2761): replace the two wall-clock ReDoS assertions with algorithmic bounds

Both guards asserted elapsed wall-clock time — `Date.now()` against a 20s
ceiling in the coherence suite, `process.hrtime.bigint()` against 1s in the
read-tolerance suite. Those measure the host machine rather than the SUT and
flake on a loaded CI runner (RULESET.TESTS.no-timing-assertion). Per
RULESET.TESTS.delete-bad-tests they are REPLACED, not skipped, and the
behavioral property each one guarded is preserved.

The property is "the widened bracket patterns do not backtrack
catastrophically", which is a claim about growth, so it is now stated by
scaling the input instead of by timing it:

- validate health runs the pathological unclosed bracket at 4,000 and 16,000
  characters and must return the same correct result (no W021) at both.
- The four reader entry points run five ReDoS shapes at 5,000 and 20,000 and
  must name exactly the phases each shape should name at each size, with the
  variant cardinality unchanged across the two.

Catastrophic backtracking is superlinear, so a regression cannot complete the
4x leg under any ceiling, while a bounded matcher is indifferent to the
scaling. The one attack that is well-formed-but-oversized now pins its reading
precisely (`['1'.repeat(n)]`) rather than being lumped in with the malformed
ones. A positive control asserts the readers still extract a well-formed
bracket heading, so "names no phase" cannot pass by the readers being inert.

`{ timeout }` is a hang backstop, not an assertion: it turns a runaway into a
deterministic failure instead of a suite that never returns.

* fix(#2761): give the bracket grammar one owner and teach the drift guard to see it

The bracket milestone-intro grammar was re-typed verbatim in three readers —
roadmap-parser's bracket-fallback selector, state's `isMilestoneBounded` and
verify's `checkBracketCoherence` — which is exactly what #2761's own gate
forbids ("no token literal outside src/phase-id.cts"). `check:phase-id-drift`
reported clean the whole time: its detector only ever knew the phase-NUMBER
token grammar, so the bracket class `[A-Z][A-Z0-9_]*` was invisible to it.

Ownership. `src/phase-id.cts` now exports the class as
`BRACKET_PROJECT_CODE_SRC` and the intro in the two shapes its readers need:
`bracketMilestoneIntroSrcFor(milestone)` (pinned to one milestone) and
`BRACKET_MILESTONE_INTRO_CAPTURING_SRC` (milestone captured). The pinned
builder owns the pad2 spelling rule too — "canonical spelling only, not `0*N`"
was previously restated in prose beside each copy, a convention two files had
to keep agreeing on by hand. `BRACKET_ID_SRC`, `BRACKET_ID_PREFIX_RE` and
`BRACKET_QUALIFIED_KEY_RE` now compose the class rather than re-spelling it.
All three call sites consume the owner; the regex sources are byte-identical to
what they spelled, asserted against hand transcriptions of the pre-fix lines.

Guard. `scripts/lint-phase-id-drift.cjs` gains a bracket rule
(`findBracketGrammarDrift`), wired into `scanRepo` and tagged `kind`. It
deliberately does NOT copy the token rule's `line.includes(CANON_REF)` escape:
that escape is line-level, and verify's copy referenced the owner for the
MILESTONE field on the same line as the re-typed PROJECT-CODE class — so a
bracket rule with that escape would have kept passing on the very site under
review. Partial ownership is the drift; only a dedicated `// phase-id-owner:`
comment suppresses it.

Proof, end to end: planting the shipped verify.cts literal back into src/ makes
`npm run check:phase-id-drift` exit 1 naming `[bracket] src/verify.cts:1475`;
restoring it returns the gate to ok.

Tests. phase-id-drift-guard carries all three shipped literals as negative
fixtures, the same-line-owner-reference case, the case-widened evasion variant,
the sanction rules, and a temp-tree scan proving the rule is wired into
scanRepo rather than merely exported. continuation-grammar-parity drives the
pinned and capturing shapes over a 12-entry corpus and requires the same
verdict from both plus the same captured milestone — widening either alone
fails there.

* test(#2761): drop the out-of-scope source-grep exemption from the selector pin

The baseline-selector pin in tests/adr-612-bracket-heading-selection.test.cjs
read `src/*.cts` with readFileSync and regex, claiming the no-source-grep
escape with a source-text-is-the-product reason. CONTEXT.md's documented scope
(RULESET.TESTS.no-source-grep.exemption) reserves that escape for tests whose
subject is a runtime CONTRACT FILE — STATE.md, config.toml, hooks.json, agent
.md — and `src/*.cts` is none of those.

It was also broader than it looked: eslint-rules/no-source-grep.cjs matches the
marker in ANY comment in the file, so one block's claim disarmed the rule for
the whole ~700-line suite.

The pin itself is worth keeping — the BASELINE ARGUMENT at each call site is a
fact no behavioural test can recover (flipping verify's milestone-complete site
from LABEL_ONLY to ANY_BRACKET grants a tolerance it has never had, and every
behavioural test still passes), so pinning it does require reading the authored
source. That reading moved to `scripts/lint-phase-id-drift.cjs` — the seam's
own guard, where source scanning is sanctioned (`warn` scope) and already
happens for the grammar rules — as `countSelectorBaselines` /
`scanSelectorBaselines`, which return a structured census. The test asserts on
the returned data and touches no file text.

CONTEXT.md is unchanged: the exemption scope was not widened to fit the test.
No marker remains in the suite, so the rule is live across all of it again, and
eslint passes with the escape removed rather than relocated. A floor assertion
pins that the census actually found the five consumers, so the "no other file
consumes the selector unpinned" check cannot pass on an empty scan.

* docs(#2761): rewrite the changeset as a lead + deltas instead of one paragraph

The fragment was a single ~6,400-character paragraph that opened on internal
mechanics, buried the user-visible change, and named an internal test path
(tests/adr-612-bracket-phase-counting.test.cjs) that means nothing to a reader
of the CHANGELOG.

It now leads with what a user sees — bracket-style phase IDs are recognized on
the read path across roadmap, validate, verify and state — followed by compact
bullets for the behavioral deltas, the opt-in caveat, and the upstream
consequences. Both merge-added disclosures are kept: the #3185 legacy-sentinel
Phase-0 delta with the reason the bracket counter keeps the narrower rule, and
the enumerator's convention-argument default flip with the four newly-scoped
read surfaces and the note that archival and milestone-completion paths are
unchanged. Two deltas from this review round are stated as their own bullets:
per-occurrence classification in `missing_phase_details`, and workstream-scoped
convention resolution including the workstream-rollup count change.

The internal test path is gone and the body is down to ~3,850 characters. The
bullets render as sub-bullets under the CHANGELOG entry and the `(#NNNN)`
suffix still lands on a trailing paragraph rather than mid-list.
`npm run lint:changeset` passes.

* test(#2761): use helpers.cleanup in the drift-guard temp-tree test

`local/no-raw-rmsync-in-tests` rejects a bare `fs.rmSync` in tests — the shared
helper carries the Windows-EBUSY retry budget. The temp-tree scan added with
M3's guard coverage test used the raw call.

* docs(#2761): correct the occurrenceKey comment on qualified-key normalization

The comment claimed `bracketQualifiedKey` is "fold- and padding-insensitive, so
`[gsd.2] 01` and `[GSD.02] 01` are one phase". The fold half is right; the
padding half is not. `BRACKET_MILESTONE_NUMERIC_SRC` is `(?:[1-9]\d{2,}|\d{2})`,
so `bracketQualifiedKey('GSD.2-01', 'bracket')` returns null and that input
takes the composite fallback instead.

No behavior change — the two key spaces use different separators and cannot
collide — but the claim was checkable and wrong. Restated: the owner case-folds,
and padding-tolerance is not a property it has or needs, because each accepted
milestone has exactly one canonical spelling and `[GSD.2]` is malformed rather
than an alternate spelling of `[GSD.02]`.

* ci(#2761): give the coverage-gate job the heap floor the shard jobs already have

The gate's report steps parse ~2.5GB of merged raw V8 dumps in one
process at the runner's implicit ~4GB ceiling, so pass/fail comes down
to GC timing (run 31338081337 OOM'd; next passes the same volume at
28s). Deterministic locally: crashes at --max-old-space-size=4096,
completes in 11s at 8192. PR shard data is within 0.15% of green next
runs — the load is pre-existing, only the ceiling was missing. #2952
set 6144 on the shard-collection step; the gate job was missed.

* Revert "ci(#2761): give the coverage-gate job the heap floor the shard jobs already have"

This reverts commit 03c74a97c911e9ddc53675aded9c9bbb89f14cd1.

* fix(#2761): thread the resolved convention into cmdStateValidate's phase-directory lookup

#3208 replaced cmdStateValidate's `startsWith` prefix test with the canonical
`phaseKeyFromDir(...) === selectedPhaseKey` comparison. That is the right
surface, and it is why the lookup now needs the resolved `phase_id_convention`,
which the rewrite does not pass.

`phaseKeyFromDir` deliberately refuses to read a bracket directory without an
explicit signal (ADR-2121: a bracket dir is string-indistinguishable from the
legacy letter-prefixed-decimal family), so un-threaded it returns the whole dir
name as the key — `GSD.02-05-real-work` -> `GSD.02-5-REAL-WORK` — while the
STATE side is the bare `05` that `parsePhaseFromProse` yields. Both sides of one
comparison derived under different conventions is #2562's defect class, and this
file's other three `phaseKeyFromDir` call sites already thread against it.

Observable: a bracket repo whose phase directory plainly exists reported
`valid: false` and "no phase directory matches phase 05", and the drift scan
(plan-count mismatch, verification status) never ran. The pre-#3208 `startsWith`
missed the same directory but skipped silently, so this is a visible-failure
regression on bracket repos, not a new miss.

Non-bracket conventions are byte-identical by construction: `extractPhaseToken`
branches only on `=== 'bracket'`, so null / 'milestone-prefixed' / unresolvable
compile the same path as the un-threaded call. The flat-legacy twin assertion
pins that.

* docs(#2761): note the cmdStateValidate convention threading in the changeset fragment

The fragment described the bracket read path as of the pre-merge branch. 504c64ff
added a shipped behaviour change — `state validate` now resolves bracket phase
directories — that the fragment did not mention, so the rendered changelog would
have under-described what ships.

Body text only; `type` and `pr` are untouched.

* test(#2761): invert the inherited-wart characterization — #3225 fixed it upstream

Required by the merge of next @ 86101ee6; test-only, no src delta.

This branch disclosed rather than fixed a pre-existing upstream wart: on a
LEGACY repo, `### Phase 999:` warned from `validate consistency` while
`validate health` suppressed it — the two verbs contradicting each other.
The case was pinned as a characterization test ("INHERITED WART, unchanged")
precisely so it would INVERT if upstream ever closed it, rather than rot
silently.

ae7dc529 (#3225) closed it, by adding the `isSentinelPhaseId` guard to this
very loop. So the assertion inverted on the merge — as designed. Flipped to
assert the FIXED behaviour rather than deleted: it is the negative-space
proof that this branch's `sentinelPhases` guard never had to grow a legacy
reading of its own, and it reds if a future conflict resolution keeps our
guard while dropping upstream's.

Added a scope control alongside it (a legacy NON-sentinel `### Phase 09:`
with no directory still warns), so deleting the loop outright cannot pass.

Union proven load-bearing in BOTH directions against the merged tree —
neither guard subsumes the other:
  - drop `isSentinelPhaseId(p)` (ours only) -> 1 red, exactly this case.
    Note upstream's own #3225 tests stay GREEN there: they cover the
    disk-side loops (sentinel dir on disk) and the gap-numbering filter,
    not the ROADMAP-side loop. This case is that site's only coverage,
    which is the second reason to keep it rather than delete it.
  - drop `sentinelPhases.has(p)` (upstream only) -> 4 red bracket suites
    (icebox-not-missing, health/consistency agreement, occurrence-aware
    suppression, checklist-index suppression).

tests/adr-612-bracket-read-tolerance.test.cjs 79 -> 80, all green.

* test(#2761): pin the three re-homed W006/W007 reads the merge left unfalsifiable

#3309/#3310 deleted the helpers this PR threaded (collectDiskPhases,
collectDiskPhaseEntries, collectArchivedPhaseDirNames,
forEachArchivedPhaseToken) and rebuilt their reads inside
src/planning-snapshot.cts + src/health-diagnostic-rules/*.cts. The convention
threading moved with them in the merge commit — but a mutation sweep over the
re-homed sites found three where reverting the convention argument changed real
CLI output and NOT ONE existing test went red. The pre-migration sites were
covered indirectly, through helpers that no longer exist, so the coverage did
not survive the relocation even though the behaviour did.

Each case is pinned at the CLI with its flat-legacy twin as the byte-identity
control, plus a non-vacuity control in the opposite direction:

  archivedPhaseTokens      revert -> "Phase 05 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for a phase whose only directory is
                                     under .planning/milestones/v1.0-phases/
  roadmapPhaseCheckboxes   revert -> "Phase 09 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for an unstarted `- [ ]` phase
  W007's extractPhaseToken revert -> "Phase GSD.02-77-orphan exists on disk"
  (roadmap-disk-consistency)         instead of "Phase 77 exists on disk"

Red/green: each single-line revert reds exactly its own case and nothing else;
every legacy control stays green in all three runs.

NOT pinned, and disclosed as droppable rather than given an unfalsifiable test:
buildValidPhaseSet's extractPhaseToken(dir, convention) in W002. That rule
unions disk tokens with roadmapDeclaredPhases and archivedPhaseTokens, and any
STATE.md reference a bracket disk token would rescue is already rescued by the
ROADMAP half — probed directly, the argument makes no observable difference. It
is threaded because it restores collectDiskPhases(planBase, convention)'s
derivation exactly, not because a test needs it.

Test-only; revertable independently of the merge commit.

* fix(#2761): three review-lens corrections to the merge resolution

Found by an adversarial pass over the re-homing, none caught by any gate.

1. planning-snapshot.cts — `phaseDirs` goes back to upstream's exact call,
   `listMilestonePhaseDirs(paths.phases, { cwd })`.

   The merge passed the resolved convention explicitly, on the belief it was a
   behaviour-preserving spelling of the lazy default. It is not. The lazy path
   resolves `resolvePhaseIdConvention(cwd, ws)` with this call's `ws`, which
   defaults to `null` — the PROJECT-only reading, no root fallback — while the
   `phaseIdConvention` field is resolved federated (workstream -> root). On a
   workstream repo whose ROOT opts into bracket and whose workstream config
   does not, those answers differ, so the explicit pass silently re-scoped
   `phaseDirs`. No test covered it in either direction (proven: reverting is
   green across all bracket + health-diagnostic + snapshot suites). PR-2 does
   not need that change, so it is dropped rather than kept untested. The
   federation guarantee is still delivered where it is observable — in the
   rules that read `snapshot.phaseIdConvention`.

2. planning-snapshot.cts — `buildRoadmapBracketIncoherencesField` decides
   file-readability BEFORE the convention gate, so `scope` means one thing on
   every repo. Ordered the other way, an absent ROADMAP.md reported COMPLETE on
   a legacy repo and UNREADABLE on a bracket one — the same "nothing to say"
   state wearing two scopes, which is exactly the non-answer/answer distinction
   ADR-3180 §8.1 gives `scope` to carry. No behaviour change (RULE_W021 does not
   read this scope); it removes an ambiguity a reader of that ADR would catch.

3. roadmap-disk-consistency.cts — `checkW006` reads
   `roadmapSentinelPhaseTokens` without its own scope guard. That is safe
   TODAY because one builder call produces it and `roadmapDeclaredPhases` from
   one `buildRoadmapPhaseVariants` result, so their scopes are yoked; the
   existing COMPLETE check covers both. Stated in a comment instead of left to
   co-location, since an UNREADABLE sentinel set degrades to "nothing is a
   sentinel", which ADDS W006 warnings rather than dropping them.

* test(#2761): pin the two reads the #3165 extraction left unfalsifiable

DROPPABLE, offered as such. Test-only; the merge commit is correct without it.

#3428's extraction gave `collectAnalyzePhases` TWO call sites — the scoped
milestone window and the truncated-window recovery path. The merge threads
`convention` into both and swaps `detailKeys` with `phases` across the recovery.
Neither of those was falsifiable by the suite as it stood:

  - passing a NULL convention at the FALLBACK site, with the scoped site still
    threaded, is green across all 518 tests of the bracket, roadmap and
    milestone-window files. Every pre-existing bracket assertion reaches the
    enrichment through the scoped window, so none of them can observe the
    fallback's reading at all;
  - dropping `detailKeys = fallbackScan.detailKeys;` — the line this merge
    authored — is likewise green, because no fixture that reaches the recovery
    path carries a checklist bullet, so `missing_phase_details` is `null`
    either way.

That is the same hole class lap 3 closed in 9914359c: an argument whose revert
changes real CLI output with zero reds.

Pinned at the CLI on the shape that reaches the fallback on a bracket repo — a
MID-MIGRATION ROADMAP: bracketed ACTIVE milestone, its phase-detail sections
and checklist bullets sitting after an intervening CLOSED legacy milestone (so
the window closes over prose only), plus one legacy `### Phase N:` section of
its own. Six tests:

  - a NON-VACUITY control that removes the phase directories, so #3428's own
    precondition fails and the result is the empty one the recovery exists to
    replace — this is what proves the rest read the FALLBACK's output rather
    than the scoped scan's;
  - the directory assertion (`disk_status`/`plan_count`/`summary_count` for
    canonical `{CODE}.{MM}-{PP}-slug` dirs) + a flat-legacy twin asserting
    byte-equal shape, and that the twin is the right answer rather than a
    shared wrong one;
  - `missing_phase_details: null` for phases the recovery just found, and its
    companion direction — a bullet with no heading anywhere is STILL reported,
    so a fix that merely suppressed the report does not pass;
  - a non-bracket repo taking the same path unaffected.

Red/green, each mutation reverted afterwards:
  - fallback call site -> `null` convention: exactly 2 reds, both directory
    assertions in this block; 307 other tests green, including upstream's own
    #3428 tests in tests/milestone-window-single-owner.test.cjs.
  - `detailKeys` swap deleted: exactly 2 reds, both `missing_phase_details`
    assertions; 414 other tests green.
  - `matchPhaseDirs` 3rd argument dropped (the lap-2 site): 4 reds — the 2
    already on record plus this block's 2, which is the point: one seam, now
    reached by two paths.

DISCLOSED IN THE TEST BODY WITH MEASURED OUTPUT, not fixed: `hasPhaseEntries`
(src/roadmap-parser.cts) is convention-blind, so on a PURE-bracket ROADMAP the
window classifies COMPLETE and #3428's recovery is gated off entirely. That
document returns `{"scope":"complete","phase_count":0,"next_phase":null,
"phases":[]}` — the "genuinely empty milestone" answer, the indistinguishability
#3184 introduced `scope` to remove — where the flat-legacy twin returns
`{"scope":"truncated","phase_count":2,...}`. Widening it changes the value of an
upstream-owned output field on bracket repos, so it is a behaviour slice (the
PR-2.5/PR-4 convention-less-readers question), not a merge-round change. The
mid-migration shape pinned here is the reachable half.

* fix(#2761): mirror the bracket terminator in the milestone-scope write guard

#3446's `findMilestoneScopeHeadingLines` is defined as a MIRROR of the
parser's terminator vocabulary — "a level 1-3 heading that is not a Phase
heading and carries a milestone signal". On this branch that vocabulary is
convention-SELECTED: `computeBracketSectionEnd` adds `isBracketMilestoneBoundary`
as a terminator arm, and the ADR-canonical `## [GSD.09] Hidden` carries NO
vN.N token, NO ✅/📋/🚧/🔄 marker, and not the word "Milestone". Left
unmirrored, the guard accepted exactly the description it exists to reject.

NOT a defect on clean next — a bracket heading terminates nothing there. The
branch widens the terminator set, so the branch owns the mirror.

MEASURED at the CLI seam before the fix (bracket fixture, one milestone,
one phase):

  $ gsd-tools phase add $'Sneaky\n## [GSD.09] Hidden'   -> exit 0, written
  $ gsd-tools phase add 'Innocent follow up'            -> exit 0, written
  $ gsd-tools roadmap milestone-scope
    { "scope": "complete", "phases": ["01","1"], "phase_count": 2 }
  $ grep '^### Phase' .planning/ROADMAP.md
    ### Phase 1: Sneaky
    ### Phase 2: Innocent follow up      <- in the document, out of the window

After the fix the first add exits 1, ROADMAP.md is byte-unchanged and no
phase directory is created. The legacy twin (same text, no
`phase_id_convention`) still exits 0 — opt-in only, base behaviour preserved.

SHAPE
- `findMilestoneScopeHeadingLines(text, convention)` — REQUIRED, the same
  tripwire `scanMilestonePhaseIds` carries in the merge commit and for the
  sharper reason: a blind call here fails OPEN (the guard quietly ACCEPTS a
  window-narrowing description), so a future call site must fail to COMPILE.
  Census is one caller, which pays nothing for it. A non-bracket value takes
  the pre-existing path byte-identically. The bracket arm routes through
  `isBracketMilestoneBoundary`, the same single-owner phase-vs-milestone
  discriminator `computeBracketSectionEnd` consults; no second bracket-heading
  grammar is spelled here.
- `selectedBracketId` is deliberately `null`, so the same-milestone
  CONTINUATION exemption never fires and a value naming the ACTIVE milestone
  is flagged too. That is this predicate's third stated conservatism and
  rests on its own existing argument: which milestone is active is a property
  of the document at write time, not of the text being validated, and
  over-rejecting is one-directional.
- `assertDescriptionPreservesMilestoneScope` takes `cwd` and resolves through
  the branch's tolerant try/catch — this guard runs BEFORE `loadConfig` and
  before the ROADMAP existence check, so an unresolvable convention must
  degrade to the legacy vocabulary, never turn a rejection into a crash.
- The error's marker list gains the bracket form only when the project is on
  the bracket convention.

RED/GREEN
- Revert the bracket arm -> 2 reds (phase add; insert + add-batch), the
  non-bracket control and both no-false-positive cases stay green.
- Revert the probe threading in the merge commit -> 1 red (the probe case).
- 6 new cases in the #3262 file, each with a non-bracket or
  no-false-positive control: fenced bracket milestone heading and bracket
  PHASE heading are both non-violations.

Droppable: revert this commit and the merge stands on its own; the branch
then ships the gap as a disclosure instead of a fix.

* docs(changeset): narrow the enumerator claim to the directory set — per-entry rendering in progress/stats/init-manager is display-slice scope

Round-7 review confirmed 3 of the 4 surfaces named by the closing claim
parse each directory or heading with legacy-only patterns that live in
files this PR does not touch (commands.cts:1766, commands.cts:2116,
init.cts:2241). The claim now states exactly what this slice delivers:
the scoped directory set. Their per-entry conversion is display work,
deferred to the epic's display PR with the statusline/progress-card
gates it belongs beside.

* fix(#2761): de-accident the unmatched-milestone bracket fixture, re-pin to #3480's withhold contract

tests/adr-612-bracket-phase-counting.test.cjs:515 ("a milestone that
does NOT match STATE is not scoped in") asserted total_phases === 0.
Since today's merge brought in 70b5c1a1 (#3354/#3480, already in
`next`), buildStateFrontmatter withholds total_phases (omits the key,
read back as null) for a milestone that is genuinely sectioned but
matches no ROADMAP heading, instead of substituting a computed number
— the fixture's `state json` read now returns null, failing the
strictEqual(0) assertion.

The original single-section fixture's 0 only ever survived by
accident: hasMilestoneSectioning requires >=2 milestone-vocabulary
headings to call a ROADMAP sectioned, and its isPhaseHeading helper
recognizes only the legacy `Phase N:` text form — so the bracket
phase heading `### [GSD.03] 09: Not this milestone` (title containing
the word "milestone") miscounted as a second milestone heading,
tipping hasMilestoneSectioning true and routing to the disk-count
branch. With that miscount removed, the same one-section fixture
reads 1 (the non-matching milestone's phase count leaking into v2.0's
total) — proving the pinned 0 was never validating the scoping this
test claims to exercise.

Replaced the fixture with two genuine milestone sections (GSD.03,
GSD.04), neither matching STATE's v2.0, with phase titles carrying no
incidental vocabulary — the real #3354 shape. Re-pinned the assertion
to null, matching upstream's own tested contract (tests/state-
document.test.cjs, "#3354 with nothing stored, the key is omitted
rather than written from the dir count").

Verified: file green 3/3 runs (104/104), full state-suite regression
771/771 green. The isPhaseHeading gap that made the old fixture
accidental is a real, pre-existing, upstream-owned limitation
(hasMilestoneSectioning only guards >=2-section conflation, not a
single non-matching section leaking through) — not introduced by
#3480 or this branch; out of scope here.

* chore(#2761): exempt two self-authored-fixture regexes from #3441's unbounded-quantifier rule

Both sites parse the STATE.md the test itself just wrote to its own
tmpdir — fixed-size fixture output, not adversarial or document-scale
input. Exempted with the justification-comment pattern the tree's own
tests use for this exact case (settings-integrations, copilot-install,
research-agent-profiles). The sites predate the rule; #3441 landed on
next this morning and this branch picked it up in the catch-up merge.

* fix(#2761): fix forward two next-movement test regressions from the round-11 rebase

origin/next's #3573 newly threads STATE's stored `milestone:` value into
`state json`'s buildStateFrontmatter call (previously always `undefined` on
that read surface). Two pre-existing PR-2 fixtures reach code paths that
call never exercised before that merge:

- RED (repro2 case C): a version-less, all-bracket-id ROADMAP now hits
  getMilestonePhaseFilter's pre-existing (unaffected by this branch) row-5
  `versionResolved && !headingFound => SCOPE.UNSCOPED` rule, which withholds
  `progress.percent` even though the scoped total_phases/completed_phases
  are still correct. That row-5 rule is load-bearing for six other
  version-less-document pins in this same file; narrowing it broke seven of
  them in testing, so production code is untouched here. Reassert the
  test's real claim (scoping, via total_phases/completed_phases) and
  disclose the now-withheld percent instead of silently dropping it.

- PIN (repro12 LEGACY control): a fenced-example-vs-real version heading
  fixture. #3573 routes this read through sliceMilestoneWindow (fence-aware)
  instead of the legacy anyMilestonePattern raw scan (fence-blind) this pin
  was disclosing as out of scope, so the fixture no longer exercises the
  blind path — total_phases moves from the whole-doc 4 to the correctly
  scoped 2. Re-pinned with an upstream-attributed comment, matching this
  file's existing house style for prior origin/next movements (see the
  sibling "PIN (G3 LEGACY control)" comment).

Both are test-only fix-forwards: no production code changed. The remaining
12 failures in this file at 27363e9d0 (dropped seam commits' VERIFICATION.md
naming + fixture updates) are pre-existing and deferred to the stacked
follow-up per the task's own scope.

* fix(#2761): thread phaseIdConvention explicitly at the two write-adjacent enumerator call sites (round-11 BLOCKER)

listMilestonePhaseDirs' phaseIdConvention param lost its `= null` default
(phase-locator.cts), so an omitted convention now means "resolve from
config" instead of "explicitly not bracket" — a deliberate flip, but
milestone.cts and state.cts were not in the PR-2 diff and both call the
enumerator without threading it:

- milestone.cts cmdMilestoneComplete (the single #3597 shared derivation
  feeding the stats loop, --dry-run preview, and the real archive/rename
  pass) now resolves phase_id_convention once and threads it explicitly,
  so a bracket project's `milestone complete` archives its real
  bracket-declared phase directories instead of silently inheriting
  whatever the enumerator's lazy default resolves to.
- state.cts cmdStateUpdateProgress's own enumerator call threads the same
  resolved convention. Empirically this does not change the #3217 withhold
  gate (scope is assigned before headingConvention resolves in
  getMilestonePhaseFilter, so it's convention-independent either way) or
  the reported percent (already correctly threaded via
  computeUpdateProgressPreview -> buildStateFrontmatter); it closes a
  second, silently-resolved answer to the same question this file's own
  ONCE-and-THREAD rule (~:2300) already states as policy.
- state.cts's other listMilestonePhaseDirs call site (the state-sync
  scope-only read, ~:4791) is left unthreaded on purpose, with an inline
  note explaining why: only `.scope` is consumed, and `.scope` is set
  before convention resolution in getMilestonePhaseFilter, so it cannot
  disagree with a threaded convention.

Both enumerated sets are pinned by new tests (round-11 BLOCKER block in
tests/adr-612-bracket-phase-counting.test.cjs), including a mutation-style
regression check on the milestone.cts fix (forcing the un-threaded default
back on makes the pinned test fail, catching a regression to the
pass-all-degrade legacy reading).

* fix(#2761): correct the changeset's false archival claim and amend ADR-612 for the round-11 M2(2) split scope

The changeset (.changeset/2761-bracket-read-tolerance.md) asserted "The
archival and milestone-completion paths are unchanged" — false: both
paths reach the widened enumerator, and this PR now threads their
convention explicitly (previous commit). Replaced the closing paragraph
with an accurate description of what changes for a bracket project at
those two call sites, and notes both enumerated sets are pinned by tests.

ADR-612 (docs/adr/612-bracket-phase-id-convention.md) amended per M2(2):
the 2026-08-03 PR-2/PR-4 boundary proposal is added in-body (PROPOSED,
not stamped — mechanics per docs/contributor-standards.md:143 reserve ADR
ratification to maintainers), rescoped to what actually ships in PR-2
(#2761) now that the round-11 M1 split moved the completion-seam
threading (isPhaseArtifact/scopeToPhase, phase-id.cts:964-1090) out into
a separate, stacked follow-up PR referenced generically via epic #612:

- state.cts read-tolerance (both total_phases derivations, the #1514
  retirement filter) moves into PR-2's row, alongside milestone.cts,
  reflecting the round-11 fix above.
- the write-observability point is restated in terms of what actually
  ships: explicit threading at two named call sites, pinned by tests,
  rather than silent inheritance.
- the completion-seam threading is named and explicitly excluded from
  PR-2's scope, with a new ratify item (5) and a Negative consequence
  bullet covering the sequencing cost.

* fix(#2761): thread convention into the #3511 membership seam — bracket dirs scope like their legacy twins

Upstream #3511's isPhaseArtifact/scopeToPhase was structurally inert on
bracket directories: 3+-letter codes (GSD.02-…) fell into the zero-token
include-everything fail-safe (PROJECT_CODE_PREFIX_CAPTURE_RE_I strips
{CODE}-, not {CODE}.), and short digit-bearing codes (A1.02-…) into the
firstLetterPrefixed one — so every bracket dir read include-everything and
a cross-phase stray could complete a bracket phase, the exact
contamination #3511 shipped to prevent, still open on this PR's own
convention.

The seam now takes the same optional trailing convention its sibling
primitives do (ADR-2121 additive shape; gated on BRACKET_DIR_TOKEN_RE, the
one grammar owner shared with extractPhaseToken's bracket branch), through
a candidate-comparison core shared with the legacy path so the two cannot
drift. Threaded by the call sites that already hold the resolved
convention: the completion chain (isPhaseComplete ->
readVerificationStatus -> resolveVerificationFile, with a convention-aware
RESOLUTION token and a deliberately convention-less command-argument
token), buildStateFrontmatter, cmdStateSync, cmdStateValidate's S006/S007
scan, the planning snapshot, and roadmap analysis. Convention-less readers
(uat, audit, init, gap-checker, phase-locator) keep the documented
fail-safe — the follow-up slice.

The phase-counting fixture now writes what cmdScaffold writes
(phase-matched ${normalizePhaseName(phase)}-VERIFICATION.md) instead of a
hardcoded 01-VERIFICATION.md that #3511 correctly reads as a stray; the
stray shape is pinned deliberately in a new regression block (measured
pre-fix: [3,3,3,2,67] with the stray counted as completion) alongside
seam-level pins for BOTH fail-safe families, so neither the rename nor a
one-branch patch can stand in for the fix.

* fix(#2761): review round — gate the FILENAME reading on the convention too, ratify the M-NN twin-parity trade

Two-leg review of the seam thread (adversarial + upstream-fit, then an
adversarial re-verify of the fixes) found and this commit closes:

- Major: the convention gated only the DIRECTORY reading. A
  milestone-qualified artifact name (GSD.02-01-VERIFICATION.md — the layout
  the read-tolerance suite models) derives zero legacy token segments, so
  FIX 2's token-less containment admitted it into ANY bracket dir. Qualified
  stems now compare on bracketQualifiedKey — exact key, or the dotted
  sub-phase continuation (the round-2 verify caught strict equality dropping
  the dot arm: over-exclusion, the dangerous direction) — while a well-formed
  stem naming a different phase or milestone is excluded. Malformed
  qualified-shaped stems keep the documented include-everything fail-safe.
- Major, RATIFIED not changed: an M-NN-stem report (02-01-VERIFICATION.md in
  GSD.02-01-one) is excluded exactly as its legacy twin excludes the same
  file; migration-window artifact renaming belongs to the migrator slice
  (ADR-612). Pinned in tests with its legacy-twin control.
- Minor: the counting fixture's verificationNameFor now routes through the
  production normalizePhaseName (padding has a single owner), and its
  docstring states honestly which artifact layout it models.
- cmdRoadmapUpdatePlanProgress threads the convention into isPhaseComplete
  (ADR-3180 §7.4 read/write-path symmetry with the analyze site).

All pins carry measured pre-fix values. Convention-less paths swept
byte-identical (1,800 comparisons, 0 differences).

* fix(#2761): mark the round-11 decoy fixture incomplete so it doesn't need a phase token

The two round-11 BLOCKER tests (cmdMilestoneComplete / cmdStateUpdateProgress
enumeration) pass a `not-a-declared-phase` decoy directory to writeProject as
an implicitly-complete fixture entry. After threading convention through the
#3511 membership seam, verificationNameFor derives the scaffolder's real
verification filename from the directory's phase token — which the decoy,
by design, does not carry. Mark the decoy incomplete instead: the assertions
these tests pin (exclusion from would_archive.phases / stats.phases) don't
depend on the decoy having a VERIFICATION file at all.

* fix(#2761): repair round-11 response gaps — disk-side sentinel bug, test-fixture bug, scanMilestonePhaseIds caller drift

Four independently-verified gaps in the round-11 repair response:

1. isSentinelPhaseId (src/phase-id.cts) treated a bare, untagged phase
   directory under phase_id_convention: "bracket" (`0-bootstrap`, no
   `{CODE}.{MM}-` prefix) as sentinel milestone 0 by falling through to the
   legacy leading-int rule when the bracket-tag match failed. This silently
   dropped a real, on-disk, milestone-declared phase directory from
   `listMilestonePhaseDirs` (phase-locator.cts:424, the only unguarded call
   site) and undercounted completed_phases/percent. Mirrors the carve-out
   already present on both heading-side counters (state.cts's
   countRoadmapPhaseHeadings guards its bare-0 exclusion with `bracketId &&`;
   roadmap-parser.cts's scanMilestonePhaseIds composes the bare-token rule as
   999-only) — under bracket convention, milestone 0 is expressed only via an
   explicit bracket tag, so an untagged leading 0 is a real phase token.

2. tests/adr-612-bracket-phase-counting.test.cjs's writeProject fixture
   hardcoded `01-VERIFICATION.md` for every "complete" phase dir regardless
   of the dir's real phase token. Under legacy convention this file already
   correctly failed #3511's strict isPhaseArtifact match for any dir other
   than phase 01 (the fixture never modeled what it claimed to); under
   bracket convention the pre-existing ambiguity fail-safe admitted it
   regardless. The two readings' disagreement was mistaken for a missing
   completion-seam threading (isPhaseArtifact/scopeToPhase convention
   awareness, correctly split out to the stacked #3644 per round-11's M1).
   Replaced the hardcoded name with verificationNameFor(dir), deriving the
   real per-phase filename from the production normalizePhaseName the same
   way cmdScaffold does — the 7 failing "flat-legacy-twin" / CHARACTERIZATION
   assertions pass on #2867's own code with no seam threading required, and
   the genuine seam-dependent cross-phase-stray-exclusion test the fixture
   fix would otherwise have hidden lives on the stacked branch instead.

3. tests/roadmap-parser.test.cjs's two #3577 tests still called
   scanMilestonePhaseIds with the old single-Set return shape; this PR
   changed it to `{ ids, qualifiedIds }` for every other caller but missed
   these two, which don't touch #2761/bracket code at all. TypeErrors at
   runtime, not silently-wrong assertions. Updated both call sites.

4. .changeset/2761-bracket-read-tolerance.md gains a paragraph disclosing
   fix 1 above, so the changeset stays accurate to what actually ships (the
   round-11 BLOCKER was exactly this changeset going stale once).

Verified: tests/adr-612-bracket-phase-counting.test.cjs +
tests/continuation-grammar-parity.test.cjs + tests/roadmap-parser.test.cjs =
354/354. adr-612-{coherence,grammar,heading-selection,read-tolerance,
selection.property}.test.cjs + collision-characterization = 287/287
(CONFIRMED-CLEAN set, unaffected). Full unfiltered suite run separately.

PR #3643 (round-11's M1 split, opened draft per that round's explicit
requirement) was auto-closed by this repo's own draft-PR policy 11 seconds
after opening — draft PRs are unconditionally closed here. Reopened as
non-draft #3644 (same branch, same commits, DO NOT MERGE / stacked-on-#2867
marker in the body, enhancement template) since the repo's own bot confirms
non-draft contributor PRs are tolerated even off-template.

* feat(#2761): gated heading-intro selection + one bracket identity grammar

Foundation. Two owner-level changes plus a federated convention resolver; no
reader consumes them yet.

1. GATED SELECTION, not an ungated widening.

   Widening every heading matcher requires the claim "no legacy ROADMAP contains
   a `[CODE.MM]` bracket followed by a digit", and that is false:
   `### [RFC.2119] 5:`, `### [v1.0] 2024:`, `### [ADR.612] 3:` and
   `### [ISO.8601] 2026:` are ordinary headings, and a widened reader claims each
   as a phase — moving phase_count and total_phases and adding W006 on projects
   that never opted in. No narrowing rescues it: the premise is about documents
   we do not control.

   `phaseHeadingPrefixSrcFor(baseline, convention, capturing?)` selects the
   pattern SOURCE at construction time. A project whose resolved
   `phase_id_convention` is not exactly 'bracket' compiles the same source string
   it compiled before. `baseline` is explicit because whether a site spells the
   any-bracket prefix or a bare `Phase\s+` is a fact about that site's history:
   handing the wider grammar to a bare site retro-grants tolerance it never had,
   in both directions — warnings appear, and a warning that fires today vanishes.

   Both bracket forms CAPTURE. `[GSD.999] Phase 07:` previously matched through
   the base alternative, which captures nothing, so a reader saw no bracket, fell
   back to the legacy token rule, and counted a labeled icebox heading while
   excluding the label-less one beside it — two derivations of one ROADMAP
   disagreeing.

2. ONE bracket identity grammar, one width rule.

   The milestone width is reconciled with the emit validator: pad2 output, so
   two digits or 3+ with no leading zero. Earlier spellings diverged in both
   directions — admitting `002`, which the validator rejects, and a bare `0` pad2
   never produces — and the section recognizers accepted `[GSD.2]`, which SCOPED
   a milestone no phase heading could then resolve into, recreating the
   on-disk-count fallback this epic removes. An unpadded bracket is now uniformly
   malformed: it scopes nothing, bounds nothing, sections nothing. W005 on its
   directories is the surfacing signal.

   The milestone field is boundary-anchored, so a malformed run cannot match by
   its prefix (`GSD.002-01` read as sentinel `00`). Recognition stays
   case-insensitive because readers compile `/i`, but identity helpers match
   `[A-Z]`, so a captured id is folded first — otherwise `### [gsd.999] 07:`
   failed every sentinel test. The qualified key shares the width, the `(?=-|$)`
   boundary and the single-sub-phase shape of the directory token, because
   phaseTokenMatches returns unconditionally on a qualified hit: a key matching a
   directory isPhaseDirName rejects would be a final wrong answer.

3. resolvePhaseIdConvention federates workstream -> root exactly as
   config-loader does — including that root is a fallback only when a WORKSTREAM
   is active, so a project-scoped directory stands alone. loadConfig cannot serve
   this: it merges against CONFIG_DEFAULTS and drops keys it does not know, and
   this key is not among them. It governs the bracket-selection reads ONLY.

PHASE_HEADING_PREFIX_SRC is left byte-identical: PR-1 shipped it, nothing
consumes it, and it is superseded rather than redefined.

* feat(#2761): roadmap.cts selects its heading grammar from the convention

Six matchers build their intro through the gated selector, and
cmdRoadmapAnalyze / cmdRoadmapGetPhase / getRoadmapPhaseWithFallback each
resolve the convention ONCE per command and thread it down.

Three sites take the any-bracket baseline (they already tolerated
`[anything] Phase N`); three take label-only (they spelled a bare `Phase\s+`).
Handing the wider grammar to a label-only site retro-grants tolerance it never
had — and not only by adding matches: on a legacy repo an unchecked
`- [ ] **[v1.0] Phase 05: Thing**` bullet would start SUPPRESSING the W006 that
fires today.

Sentinel handling under bracket ADDS a rule rather than replacing one: a
bracketed heading is a sentinel when its bracket milestone is reserved
(`### [GSD.999] 01:`) OR when its token is, so the engine-wide 0/999 backlog
convention keeps applying to `### [GSD.02] 999:`. Replacing the token rule let a
mid-migration ROADMAP — bracket headings plus a legacy backlog block, exactly
the content this epic targets — add entries to the progress denominator. The
captured id is folded before the identity test, so a lowercase
`### [gsd.999] 07:` is excluded too.

The DIRECTORY read is threaded too. `cmdRoadmapAnalyze` resolves the convention
once and hands it to all four of its heading/checklist patterns, but the single
`phaseTokenMatches` call that decides `disk_status`, `plan_count`,
`summary_count`, `has_context` and `has_research` was left two-argument — so
every canonical `{CODE}.{MM}-{PP}-slug` directory read as `no_directory` with
zero counts, on the PR's own headline verb, while the SAME build resolved those
same directories correctly in three other places on the same repo (W006/W007 via
phaseTokenFromDir, `state json` via the milestone filter, and the W021
milestone-complete read through this very helper's three-argument form). It
failed ONLY for the directory shape the convention exists to name: a
mid-migration bracket repo carrying legacy `01-one` dirs resolved fine, which is
why nothing caught it. Measured, bracket vs its flat-legacy twin:
`[["01","no_directory",0,0],["02","no_directory",0,0]]` against
`[["01","complete",1,1],["02","planned",1,0]]`.

The oracle is the twin, computed in the same test run, plus exact literals —
`grep disk_status tests/adr-612-*` was zero hits before this, so neither the fix
nor a future regression had any gate at all.

Disclosed: a ROADMAP written in bracket form before config.json is switched
reads as empty rather than mis-counted. Silent invisibility during the migration
window is the deliberate trade against claiming phases on projects that never
opted in.

* feat(#2761): validate.cts selects its grammar; gated directory recognition

The W006/W007 feeders take the resolved convention as a threaded parameter.
These sites carry the letter-tolerant `[\w][\w.-]*` capture, which makes them
where an ungated widening does the most damage: `### [RFC.2119] 5:` enters
roadmapPhases as a phantom and becomes a W007 "in ROADMAP.md but no directory on
disk" on a project that never opted in.

buildRoadmapPhaseVariants also surfaces the tokens borne ONLY by sentinel-bracket
headings. Surfaced rather than filtered in place because roadmapPhases feeds both
a membership check and a missing-directory warning, and only the latter should
ignore an icebox item.

That set is OCCURRENCE-AWARE, and the subtlety is load-bearing: roadmapPhases is
a TOKEN set, so `[GSD.999] 01` and `[GSD.02] 01` collapse to one entry. Keying
suppression on the token alone let an icebox heading silence a REAL phase that
happens to share its number — a false negative strictly worse than the warning it
removed. A token is suppressed only when no non-sentinel heading bears it.

Directory recognition is added as gated FUNCTIONS beside the exported RegExp
constants, which stay byte-identical: the `{CODE}.{MM}-` prefix is
string-indistinguishable from the letter-prefixed-decimal family this repo
documents as ambiguous, and folding a branch in changes those constants' answers
on exactly that family. A RegExp constant has nowhere to attach a gate.

The recognizer mirrors the emit grammar and delegates the token to the canonical
owner, so recognizer and resolver agree on rejected input as well as accepted.
Both functions throw on a non-string, matching the call pattern they replace.

buildRoadmapPhaseVariants' CHECKLIST scan is capturing, like its heading twin
and like the sibling checklist scan in roadmap.cts, and for the reason that one
states: the bracket id has to ride along or the sentinel filter is blind to
`- [ ] **[GSD.999] 01: Icebox**`. Left un-capturing, the scan called every
checklist token REAL, and the occurrence-aware un-suppression loop then deleted
the icebox token the HEADING scan had correctly marked sentinel — so `validate
consistency` warned that a bracket ICEBOX phase had no directory, in the HOUSE
ROADMAP shape where an icebox appears as both a bold bullet and a detail
heading. `validate health` stayed silent on that same repo, so the two verbs
disagreed — which is the disagreement `sentinelPhases` exists to close.

Both directions are pinned, because the failure mode of a careless fix here is
the opposite one: a real phase sharing a sentinel's token must still warn. It
does, in all four shapes that attack it (sentinel heading + real bullet,
lowercase sentinel, sentinel after the real heading, colon-less bullet).

* fix(#2761): count bracket headings, and retire them, in both derivations

Both `total_phases` derivations select their grammar from the resolved
convention, in one commit — cmdStateSync already carries the comment that it
mirrors buildStateFrontmatter "so both report consistent percents (#3242 Bug B)",
so teaching one and not the other ships that divergence.

The #1514 retirement filter widens WITH the counter it protects. The canonical
gesture strikes the checklist BULLET and leaves the detail heading intact, so a
bracket-form retirement went undetected and the phase stayed in the denominator
forever. That is half a fix alone: the retired key is compared against
phaseKeyFromDir, which called extractPhaseToken with no convention. Both halves
land here.

Under bracket the sentinel token rule composes as the full engine set {0, 999},
so this counter agrees with `roadmap analyze`, which has always excluded both —
otherwise the two derivations report different numbers for one ROADMAP and the
changeset's "excluded from every count" is false as written. The LEGACY path
keeps its pre-existing 999-only rule: widening it there would move legacy totals,
so the two stay split off the bracket path exactly as they are today.

The sync-side assertion reads the PERCENT sync writes into the STATE.md body, not
the frontmatter total_phases. Sync's own counter never reaches that field — the
read derivation writes it — so asserting the frontmatter after a sync measures the
read path twice and lets a mutation to the write-path guard survive.

* feat(#2761): verify.cts bracket-coherence W021 + selected milestone-complete read

The shipped milestone-prefixed W021 gate keeps its ROOT-only config read,
verbatim base semantics. Federating it silently moved a legacy convention's
answer in BOTH directions on workstream repos — a W021 that fires at base
vanishing, and one that is silent at base firing. resolvePhaseIdConvention
governs the new bracket-selection reads only.

B6, the milestone-complete check, keeps its ungated POSTURE (bug-557 pins it
with an empty config) but selects its grammar from the convention. Inferring
'bracket' from the shape of a matched bracket ran a repo-failing check against a
legacy ROADMAP that merely contained `### [RFC.2119] 5:`. Directory resolution
widens with the heading read, so a bracket repo whose phases are on disk stays
silent, and a bracket sentinel is not reported as unstarted.

checkBracketCoherence is advisory and gated. Anchored to tokenizeHeadings so
fenced examples cannot warn and heading level is structural. Its scope rules each
close a way it silently did nothing or fired wrongly: only a genuine MILESTONE
heading opens or closes a section (a `### Notes` used to reset scope and disable
both sub-checks); a legacy `## v3.0` DOES close it; an M-NN or letter-suffixed
phase heading raises missing-bracket and CONTINUES; a bare `#### 2026:` is not a
phase; the full h2-h6 range is processed. Its section recognizer shares the one
milestone width, so an unpadded `### [GSD.3] 05:` can no longer be a phase to the
id grammar and a section to the section grammar at once, silently re-scoping
every warning after it.

validate consistency suppresses bracket sentinels in its missing-directory
warning — the two verbs disagreed, health suppressing via notStartedPhases while
consistency did not. The legacy reading is untouched, including its pre-existing
wart that `### Phase 999:` still warns there.

* fix(#2761): scope the milestone by its bracket; select the disk-side filter

Two roadmap-parser reads, both of which made a bracket project's totals track
the disk instead of the ROADMAP.

The ADR pins the bracket milestone heading as `## [GSD.02] Foundation` — a name,
no version — but scoping matched STATE's `milestone: v2.0` STRING against a
heading, so the canonical form matched nothing and total_phases fell back to the
directory count. The rule was re-derived in THREE places: extractCurrentMilestone
plus two `milestoneBounded` guards; fixing one left the others falling back
regardless, so they are now one gated helper. It matches the CANONICAL padded
spelling only — accepting `0*N` bounded a milestone whose phases were invisible,
which un-suppressed a progress percent computed off an unscoped disk count.

getMilestonePhaseFilter's heading scan becomes the 14th selected read. On a
bracket ROADMAP it collected nothing, so the filter degraded to pass-all and
buildStateFrontmatter counted every other milestone's directories — making the
bracket convention strictly worse than the M-NN one it supersedes on the property
that matters most: totals must track the ROADMAP, not the disk.

The DIRECTORY side of that same filter is selected with it. Teaching only the
heading scan was half a fix and a worse one: `milestonePhaseNums` became
non-empty, so the pass-all degrade stopped firing, but no bracket directory could
satisfy the three legacy dir checks (numericRe fails on `GSD.02-05-five`, the
custom-id match captures the project code `GSD`, and stripProjectCodePrefix does
not strip a dotted prefix). Every bracket directory was rejected, and
completed_phases / total_plans / completed_plans / percent all collapsed to 0
while `state sync` went on writing a percent off the unfiltered disk — `state
json` reporting 0% on the same repo, in the same second, that STATE.md's body
called 67%. That is the #3242 Bug B divergence this PR exists to avoid, and
total_phases could not show it: `Math.max(phaseDirs.length, roadmapPhaseCount)`
floors it at the ROADMAP count no matter how many directories are rejected.

The dir side matches on the milestone-QUALIFIED id, delegated to the owner's
gated `phaseTokenMatches(dir, id, 'bracket')`, not on the bare token: READING-B
puts the milestone in the bracket, so `GSD.01-01-old-one` and `GSD.02-01-one`
share the token `01` and only the qualified key separates them. The qualified ids
are kept in their own set — a hyphen in `milestonePhaseNums` would flip
`roadmapUsesHyphenedIds` and silently move the LEGACY dir path on a bracket repo
— and the branch is ADDITIVE: on a miss it falls through to the three legacy
checks, so a bracket project carrying legacy-shaped directories reads unchanged.

Both are resolved lazily and gated, so the legacy path pays neither a config read
nor a second scan and cannot change answer. The scoping call is also GUARDED:
resolvePhaseIdConvention reaches planningDir, which throws a plain Error for a
GSD_PROJECT/GSD_WORKSTREAM segment carrying `/`, `\` or `..`. At base the only
planningDir call in extractCurrentMilestone sits inside the STATE-read try, so
the function returned normally on such an environment; an unguarded one here let
that escape and broke the never-throws invariant that getRoadmapPhaseInternal and
getMilestoneInfo three hundred lines below carry #2245 / ADR-227 notes about.
Unreachable through the CLI — GSD_WORKSTREAM is rejected up front by the
workstream-name policy and GSD_PROJECT throws identically at base — but reachable
by any in-process embedder, which is precisely who that invariant is for. The
filter's own resolve call was already inside its try and is unaffected.

The milestone-qualified key is formed only for a token that is itself a bracket
phase token. `${bracketId}-${token}` is a string SPLICE, so a mid-migration
heading carrying an M-NN label — `### [GSD.02] Phase 02-01:` — spliced to
`GSD.02-02-01`, which the qualified-key grammar reads as milestone 02 / phase 02:
the `-01` truncated, both such headings collapsing to one key, and the heading
claiming `GSD.02-02-two`, the directory it does NOT name, while rejecting
`GSD.02-01-one`, the one it does. The guard drops those headings back to the
unqualified legacy path, restoring the base ACCEPTANCE VECTOR exactly — pinned
against the milestone-prefixed reading of the same ROADMAP, which is
base-identical on this shape.

Scoped precisely, because the fixture moves one number that the guard does not
touch: `total_phases` on it reads 1 at base and 2 here. That is the bracket
heading COUNT this PR exists to add, not the splice — measured identical with and
without the guard, and identical to what the canonical `### [GSD.02] 01:`
spelling does on the same fixture (both read 2 with zero directories on disk,
where base reads 0). The claim is base-equivalent ACCEPTANCE, not a
base-equivalent reading.

One consequence is stated rather than fixed: a heading whose token carries a
hyphen still puts that hyphen into milestonePhaseNums and so still flips
`roadmapUsesHyphenedIds`. Base does the same for that spelling, so preserving it
is what keeps the shape base-equivalent; excluding the token would have moved
answers versus base on malformed input. The comment at the qualified-set
declaration is corrected to claim only what is true — it keeps QUALIFIED IDS out
of that flag's input, not hyphens in general.

The oracles ship with it, and they are the five numbers, not the one: the parity
gate now asserts total_phases, completed_phases, total_plans, completed_plans AND
percent, on both derivations, on two fixture shapes (one milestone; two
milestones with stale prior-milestone directories on disk). The oracle is the
flat-legacy twin, built in the same test run and compared number for number,
plus exact literals so a shared wrong answer cannot pass.

The oracle SUBSTITUTION is itself pinned. The M-NN spelling of these shapes could
not serve, because buildStateFrontmatter's #2445 de-dup key captures only a
directory's leading integer and collapses `02-01-one` / `02-02-two` /
`02-03-three` to one — measured [3,0,1,0,0] against the flat-legacy twin's
[3,2,3,2,67], identically at base and before this fix, and structurally
unreachable from the bracket key space. That reasoning is only sound while it
stays true, so a characterization test holds the M-NN reading down on the two
numbers that do not depend on which directory wins the mtime race. Widen the
de-dup key and it fails, instead of quietly invalidating the changeset's
disclosure.

Also adds the call-site pin. The structural table pins transcription against the
selector; it cannot see a call site whose BASELINE ARGUMENT is wrong. Flipping
verify.cts's milestone-complete site to the wider baseline grants a
fires-on-every-repo check tolerance it has never had, and every behavioural test
still passed. The pin reads the shipped sources and asserts the mode at each of
the 14 sites, count-exact.

* test(#2761): pin the bracket read surfaces in the parity gate

This gate exists because #2043 fixed one bug across five hand-edited copies of a
rule and #2232 was the residual that survived, because a later reader could not
tell the copies were one rule. PR-2 adds two consumers, so they belong here.

Surface 7 — the heading read and the directory read must agree about WHICH phase
a `MM-<seg>` pair names, across the shared width corpus, and the bracket and
legacy spellings of one heading must yield the same token.

Surface 8 — the two bracket directory readers, in BOTH directions. Agreement on
ACCEPTED input was already pinned; agreement on REJECTED input is where they
actually diverged.

* chore(#2761): changeset

Disclosures for the PR body (deliberate, not defects):

- phase_id_convention is not a CONFIG_DEFAULTS key, so loadConfig drops it and
  cannot serve as the convention resolver however the file is federated. This PR
  ships its own workstream->root resolver; adding the key and its value enum is
  later-slice work.
- Convention matching is strictly === 'bracket'. A misspelled value reads as
  not-configured and the project keeps legacy behaviour silently.
- An UNPADDED bracket milestone (`[GSD.2]`) is malformed: it scopes nothing,
  bounds nothing, sections nothing, and is not a phase id. W005 on its
  directories is the surfacing signal.
- WIDTH UNIFICATION MOVED FOUR MERGED PR-1 EXPORT ANSWERS on non-canonical
  inputs, none of which toDir can emit and none of which had a bracket caller at
  base:
    isSentinelPhaseId('GSD.0-01',    'bracket')  true  -> false
    isSentinelPhaseId('GSD.0999-01', 'bracket')  true  -> false
    getMilestoneFromPhaseId('GSD.2-01',   'bracket')  'v2.0' -> null
    getMilestoneFromPhaseId('GSD.002-01', 'bracket')  'v2.0' -> null
  The canonical pad2 sentinel spelling `[GSD.00]` still tests true.
- FLAG TO MAINTAINER: docs/adr/612:132 reads "Sentinel behavior (0.x / 999.x ->
  milestone null) is preserved". After the unification that holds for the
  canonical `00` spelling only, not for a bare `[GSD.0]`. ADR wording is yours;
  flagging the tension rather than editing it.
- The bracket sentinel rule COMPOSES with the legacy one — a bracketed heading is
  a sentinel when its bracket milestone OR its token is reserved. Under bracket
  the state-side token rule is the full {0, 999} set so both derivations agree;
  the LEGACY path keeps its pre-existing 999-only rule, unchanged.
- validate consistency's legacy reading is untouched, including the pre-existing
  wart that `### Phase 999:` warns there while validate health suppresses it.
- find-phase still cannot resolve a bracket phase directory. phase-locator.cts is
  outside this PR's module set. Sibling PR #2559's matchPhaseDirs calls
  phaseTokenMatches without a convention, so whichever slice lands second must
  thread it through.
- Four of the five bracket readers scan raw ROADMAP content, so a bracket heading
  inside a fenced code block is read as a phase. Pre-existing for the legacy
  spelling; parity, not a new class.
- roadmapPhaseLookupSources gained no bracket source: nothing emits a
  milestone-qualified query into it yet.
- roadmap validate remains a separate, unfederated convention reader.
  Pre-existing and base-identical, but two verbs can disagree about the active
  convention on one project.
- _diskScanCache keys on cwd while the values it caches are now
  convention-dependent. Not reproducible through the CLI; pre-existing for the
  workstream dimension, widened here. Stated as inconclusive.
- A ROADMAP written in bracket form before config.json is switched reads as empty
  rather than mis-counted — the deliberate migration-window trade.
- THE READ AND WRITE PERCENTS STILL DIVERGE ON A MULTI-MILESTONE REPO, and that
  divergence is MIRRORED under bracket rather than closed. buildStateFrontmatter
  applies the milestone filter; cmdStateSync does its own fs.readdirSync and never
  calls it, so on a repo carrying prior-milestone directories the read path
  reports the SCOPED percent and the sync body reports the WHOLE-DISK one.
  Measured on the true base build (d04592de), flat-legacy spelling, 3 in-scope
  phases with 1 complete plus 2 stale prior-milestone dirs: `state json`
  [3,1,3,1,33], sync body 60%. The bracket twin of that repo now reads the same
  two numbers — 33 and 60. Scoping the sync counter would move every legacy
  repo's percent, which a bracket read-path PR must not do. The gate pins both
  sides, so the mirror cannot silently become a one-sided fix.
- THE PARITY ORACLE IS THE FLAT-LEGACY TWIN, NOT THE M-NN ONE, and that is a
  measurement finding rather than a preference. buildStateFrontmatter's #2445
  de-dup key captures only a directory's LEADING integer, so the M-NN dirs
  `02-01-one` / `02-02-two` / `02-03-three` all key to `2` and two of the three
  are dropped before they are ever counted: base reads [3,0,1,0,0] where the
  flat-legacy twin of the same repo reads [3,2,3,2,67]. Present identically at
  base and at HEAD, untouched here, and structurally unreachable from the bracket
  key space — `GSD.02-01-one` does not match that pattern at all, so every bracket
  directory keys to its own name. The source line already carries a
  `phase-id-owner:` sanction recording the divergence. Mirroring it under bracket
  would mean manufacturing a collision that cannot occur, so the gate compares
  against the flat-legacy spelling, which is uncontaminated. This paragraph is
  itself pinned: a characterization test holds the M-NN reading on the two
  numbers that do not depend on which directory wins the mtime race, so widening
  the de-dup key in a later slice fails the suite rather than silently making
  this disclosure false.
- THE `phaseTokenMatches` CALL-SITE CENSUS, stated so the remaining gaps are
  auditable rather than implied. 13 call sites outside the owner (phase-id.cts).
  THREE are three-argument: verify.cts:2229 (the W021 milestone-complete read,
  already was), roadmap.cts:436 (`roadmap analyze`'s directory lookup, threaded
  by this PR) and roadmap-parser.cts:792 (the disk-side milestone filter, added
  by this PR). The other TEN are two-argument and stay that way — phase.cts ×5
  (220, 277, 444, 585, 1547), phase-locator.cts:62, smart-entry.cts:243,
  init.cts:1414, milestone.cts:551 and verify.cts:2467. All ten are untouched by
  this PR and base-identical.
  One of them sits in a file this PR DOES edit, so it is named rather than left
  to a reader's grep: verify.cts:2467, `verify schema-drift <phase>`. Measured on
  a bracket repo across base / pre-fix branch / this HEAD, all three agree on all
  three argument forms — `verify schema-drift GSD.02-01` and `… 01` both report
  "Phase directory not found" on every build, and `… GSD.02-01-one` resolves on
  every build through the exact-directory-name fallback. So the user-visible
  shape of what stays broken is: a bracket phase is addressable there by full
  directory name only, exactly as at base. Threading the convention into a
  function this PR never touched, in the last round before ship, is the wrong
  trade; it is where the same one-argument fix goes next, alongside
  milestone.cts:551 and init.cts:1414.
- A BRACKET HEADING WHOSE TOKEN CARRIES A HYPHEN (`### [GSD.02] Phase 02-01:`,
  a mid-migration spelling) forms NO milestone-qualified key, and therefore
  scopes through the unqualified legacy path — base-equivalent ACCEPTANCE, which
  is the claim, and not a base-equivalent reading: `total_phases` on that shape
  moves 1 -> 2 for the same reason it moves on the canonical `### [GSD.02] 01:`
  spelling, because counting bracket headings is what this PR does. Such a token
  still flips `roadmapUsesHyphenedIds`, as it also does at base. The comment at
  the qualified-set declaration now claims only that narrower, true thing.

The `pr:` field carries the sub-issue number as a placeholder — it must be
updated to the real PR number when the PR is opened.

* chore(#2761): point the changeset at PR #2867

* test(#2761): fast-check properties for the convention-selection layer

CONTRIBUTING.md mandates a generative property test for parser/bijective-contract
changes; PR-2 shipped six example-based files and none. This adds the missing
layer, scoped to what PR-2 actually contracts — WHICH pattern each reader
compiles, decided by the resolved `phase_id_convention` — rather than restating
PR-1's grammar round-trip properties, which already live in
tests/adr-612-bracket-grammar.test.cjs.

Four properties: P1 an opted-in repo reads the ADR-canonical label-less bracket
heading/dir and a non-opted-in repo is byte-blind to the identical input; P2
every non-bracket convention agrees with the hand-transcribed BASE source over
generated content, including bracket-DOTTED legacy prose (`[RFC.2119] 5:`) that
must never be claimed as a phase; P3 nine per-field mutations are rejected and
the one case variation folds instead; P4 both sides of a phase comparison derive
the same key under the same convention.

Generators template every input from raw primitives — nothing is seeded through
renderPhaseId/toDir, the p2() tautology that made #2258 round 1's property test
structurally unable to find B1. Domain reaches past 99 into the 3+-digit branch
(round 2's numArb-capped-at-99 miss), forces sub-phases in at weight, and pins
both sentinel milestones.

Falsified against the COMPILED lib, not the source: five deliberate mutants
(gate never fires; gate always fires; milestone width widened to \d+; the #612
convention forwarding dropped from phaseKeyFromDir; extractPhaseToken's bracket
branch ungated) each fail the specific property that should catch them —
16/2, 16/2, 15/3, 17/1, 17/1 pass/fail — and the lib restores byte-identical.

An earlier draft of P2 held vacuously: its base regex omitted the markdown
furniture the selected one carried, so every realistic `### Phase NN:` line
matched neither side. The gate-always-fires mutant did not kill it. Both are now
compiled through one function, and that mutant kills P2.

* test(#2761): adversarial malformed bracket tokens across the tolerant readers

The existing boundary coverage stopped at shapes the emit grammar rejects
(unpadded `[GSD.3]`, wrong-case, `12A`). It never exercised a STRUCTURALLY
broken token — a non-numeric milestone, a bracket that never closes, a bracket
nested in another — which is the input a tolerant reader is most likely to
half-read, and the one the PR's own regex commentary is explicit about.

read-tolerance (roadmap heading scan + validate's dir and variant builders):
ten malformed headings, each asserted to be read as a phase by NO convention and
to give the opted-in repo the same answer as the legacy one; the corpus driven
through `roadmap analyze` end to end; malformed DIRECTORY names asserted
unrecognized and non-throwing on all four conventions; and the two variant
builders asserted to agree, since a widening that reaches only one splits
`validate consistency` from `validate health` (the #3242 Bug B shape).

coherence (verify.cts W021): the same six broken shapes asserted to raise no
W021 of their own AND not to re-scope the W021 that follows them — the G2
failure mode reached from a different shape, where a heading that is not a phase
but IS read as a section silently moves later warnings onto the wrong milestone.

Both files gain a pathological-input time bound. Nested quantifiers over a long
unclosed bracket are the classic ReDoS shape and two commits on next (#2828,
#2944) were CodeQL-flagged for exactly that, so the bound is asserted rather
than argued from reading the pattern. The probes themselves parse no regex.

* docs(#2761): document "bracket" as a phase_id_convention value

The row listed only `"milestone-prefixed"` and `null`, so after two shipped
slices (#2258 grammar, this PR's read path) the convention had no documented
enum value. CONFIGURATION.md is also a top-10 historical co-changer of both
src/verify.cts and src/state.cts and was absent from this PR.

The row states the boundary rather than the ambition: `"bracket"` changes the
READ path only, there is no migrator and no emit yet, and a project on any other
value compiles the patterns it compiled before. That keeps the docs honest for
the two releases before PR-3 and PR-4 land, instead of describing a convention a
user cannot yet migrate to.

* chore(#2761): retype the changeset Added, drop the docs-exempt marker

`Fixed` was wrong by CONTRIBUTING.md's own definition — a fix restores
documented behavior, and bracket read tolerance is the second slice of a
capability that did not exist before #2258. The type also carried a
`docs-exempt` marker, and `Fixed`/`Security` are exempt from the docs-required
lint, so the typing had the effect of routing around a gate this change should
pass. It now passes it: `lint-docs-required` returns ok_docs_updated on the
CONFIGURATION.md row added in the previous commit.

Body gains one sentence pointing at that row and restating that `"bracket"` is a
read-path opt-in until the migrator and write path land.

* test(#2761): pin the version-less bracket milestone scoping gap; narrow the claim

The changeset asserted that milestone scoping "recognises the ADR-canonical
`## [GSD.02] Foundation` heading and applies to the phase DIRECTORIES too." A
CLI probe on that exact heading form falsifies the second half: with no `vN.N`
in the milestone heading the directory side does not scope, and directories from
BOTH the prior and the later milestone are admitted. Measured 4 dirs counted
where the milestone declares 2.

Every bracket fixture in the suite writes `## [GSD.02] v2.0: …`, so nothing
covered the form the ADR actually specifies — and the state.cts doc comment
calls that version-less form canonical.

Mechanism, in extractCurrentMilestone: the bracket scope branch selects the
right currentSection, but `preambleCutoff` keys off a pattern requiring a
version or status emoji, so a version-less roadmap falls back to the current
milestone's own offset and every PRIOR milestone lands in the preamble — whose
phase-stripping regex only strips `Phase N:`-labelled headings, so bracket phase
headings survive it. Independently, `computeSectionEnd` accepts a boundary only
on a version/emoji heading, so the section runs to EOF and every LATER milestone
is swept in. Two sites, bidirectional.

Not fixed here: it changes milestone scoping, which is shared with the legacy
path. Five characterization tests pin today's reading plus a versioned CONTROL
proving the version string is the only difference, and the changeset sentence is
narrowed to what the code does. The DEFECT assertions are written to be
INVERTED by the fix, not deleted — that inversion is its regression proof.

* docs(#2761): re-anchor the branch's own cross-file line citations after the rebase

Three of this branch's code comments cite sibling call sites by line number, and
the rebase onto 178ec000 moved two of the three targets:

  roadmap-parser.cts  validate.cts:210 -> :218   (const g = capturing ? 1 : 0)
                      state.cts:1715   -> :1752  (const bg = … 'bracket' ? 1 : 0)
  roadmap.cts         verify.cts:2229  -> :2355  (phaseTokenMatches 3-arg form)

`state.cts:1715` had drifted 37 lines and now lands on the retirement skip, not
the capture-offset idiom the sentence is about — the citation read as evidence
for a claim the cited line does not support.

planning-workspace.cts's `config-loader.cts:618/:649` was checked and is still
correct; left alone.

Comment-only. Build, drift guard and the bracket suites re-run unchanged.

* fix(#2761): scope the version-less bracket milestone heading too (B1)

computeSectionEnd and the preambleCutoff scan in extractCurrentMilestone
(roadmap-parser.cts) only recognized a milestone boundary heading that
carried a vN.N token or a status emoji. The ADR-canonical bracket
heading (## [GSD.02] Foundation) carries neither, so on that shape
computeSectionEnd fell through to content.length (sweeping every LATER
milestone into scope) and preambleCutoff fell back to the current
milestone's own offset (leaking every PRIOR milestone's bracket phases
into the preamble, whose Phase-N: strip regex never matches them).

Under the bracket scope branch, both sites now also accept a
`#{1,2}\s+\[CODE.MM\]` boundary, built from phase-id.cts's BRACKET_ID_SRC
(single owner of the bracket-id grammar) rather than a re-typed literal.
`#{1,2}` is the deliberate discriminator: a bracket PHASE heading is
level 3 and shares the same `[CODE.MM]` prefix, so a `#{1,3}` boundary
would swallow it too. Reachable only when bracketScopeConvention ===
'bracket' was already resolved (i.e. the bracket scope branch actually
fired), so version-bearing/emoji headings and non-bracket conventions
take the exact pre-existing code path byte-identically — confirmed by
the full adr-612 suite staying green.

Inverts the four DEFECT assertions in the
"#612 PR-2 CHARACTERIZATION: a version-less bracket milestone does not
scope" describe block (tests/adr-612-bracket-phase-counting.test.cjs)
into their regression-proof form, per the block's own doc comment, and
reframes the describe title/comments accordingly. Corrects the
.changeset/2761-bracket-read-tolerance.md fragment, which described the
directory-side version-less gap as an open, un-closed bound.

* fix(#2761): thread sentinelPhases into validate health's W006 loop (B2)

cmdValidateHealth's W006 loop (src/verify.cts) destructured only
roadmapPhases from buildRoadmapPhaseVariants, not sentinelPhases —
unlike cmdValidateConsistency, which already skips sentinelPhases with
the identical guard a few hundred lines up. A heading-only bracket
icebox/pre-milestone entry ([GSD.999] / [GSD.00]) therefore gained a
false W006 "no directory on disk" from validate health while validate
consistency correctly stayed silent on the very same ROADMAP — the two
validators contradicting each other.

Threads sentinelPhases through and skips it before the existsOnDisk
check, mirroring the consistency guard exactly. Gated the same way
sentinelPhases already is (empty unless phase_id_convention is
'bracket'), so a legacy repo's W006 reading — including its own
pre-existing wart where a legacy `### Phase 999:` still warns on both
verbs — is untouched; confirmed by the existing "INHERITED WART,
unchanged" test staying green.

Adds the paired-agreement regression test (#612 PR-2 B2 describe block
in tests/adr-612-bracket-read-tolerance.test.cjs): a sentinel-only
bracket roadmap must produce no missing-directory warning from EITHER
validator, plus a CONTROL proving a real phase with no directory still
warns on both. Confirmed red (health false-W006) against the pre-fix
code before applying the fix.

Corrects the .changeset/2761-bracket-read-tolerance.md fragment, which
described the asymmetry as already closed and in the wrong direction
(it credited validate health with already staying silent, when health
was the one falsely warning).

* test(#2761): pin mixed-shape preamble cutoff and boundary heading levels

Closes two self-flagged coverage gaps in the B1 fix (commit 08d5b0c4)
ahead of adversarial review. No src change — all three new tests are
green against the code as committed.

1. earliest-of-either preambleCutoff comparison: only exercised where
   the version/emoji match and the bracket match happen to land on the
   same heading. Adds the mid-migration mixed shape (version-bearing
   PRIOR + version-less CURRENT) and asserts scoping outcomes (accepts
   booleans + total_phases), not internals.

2. `h.level <= 2` conjunct in computeSectionEnd: provably redundant
   whenever the selected milestone heading is level 2 (every existing
   fixture), since `h.level > level` alone already implies it there —
   a mutant deleting the conjunct would have survived every prior test
   in this file. Adds a level-3 CURRENT-heading fixture (with a real
   PRIOR milestone so the preamble side-channel can't independently
   rescue the truncated phases) that makes the conjunct's deletion
   test-visible, confirmed by hand-mutating a throwaway copy of the
   compiled output (never touching tracked src or the real build) and
   observing the assertion flip. Also pins a level-1 companion case
   (#{1,2} tolerance, not just level 2).

NOT included here: the other mixed-shape direction (version-less PRIOR
+ version-bearing CURRENT) turned out to be a genuine, currently-unfixed
gap — reported separately rather than silently patched or weakened, per
instruction not to touch src while a probe run is in flight.

* fix(#2761): engage bracket boundaries when the current milestone heading is version-bearing (B3, self-caught)

Found during round-2 self-verification of B1 (commit 08d5b0c4), while
closing the mixed-heading-shape coverage gaps flagged in my own review
notes. The B1 fix resolved `bracketScopeConvention` only inside the
`if (headingMatches.length === 0)` gate that also drives SELECTION's
own bracket fallback (which heading counts as "current"). That gate is
correct for selection, but `bracketScopeConvention` also feeds
computeSectionEnd's and preambleCutoff's boundary detection further
down — which accidentally inherited selection's gate instead of having
its own.

Trigger shape: the CURRENT milestone heading is itself version-bearing
(`## [GSD.02] v2.0: Current Milestone`), so the primary version-string
match succeeds immediately — headingMatches.length !== 0 from the very
first check — and the entire bracket-resolution branch was skipped. A
sibling milestone (PRIOR or LATER) that is version-less then got
neither the version/emoji boundary rule (it has none) nor the bracket
boundary rule (never resolved), reproducing the original #612 defect
(total_phases falling back to the whole-disk count) through a
structural shape B1's own fixtures never exercised — every one of them
is uniformly version-bearing or uniformly version-less across all
three milestones, never mixed with CURRENT specifically being the
version-bearing one.

Fix: resolve `bracketScopeConvention` unconditionally, decoupled from
`headingMatches.length`. SELECTION is deliberately left untouched — the
`if (headingMatches.length === 0 && bracketScopeConvention === 'bracket')`
fallback that picks which heading is "current" keeps its original gate
byte-for-byte (confirmed by diff: that line is unmodified). Only the
convention *resolution* moved out from behind it, so boundary detection
can consult it regardless of which branch selected the heading. The
extra `resolvePhaseIdConvention` call this now costs on every
invocation (previously paid only when the version match found nothing)
is the accepted cost: a non-bracket repo still resolves to something
other than 'bracket' (or null on a poisoned env, caught exactly as
before), so `bracketMilestoneHeadingRe` stays null and every downstream
branch is byte-identical to today — confirmed by the full adr-612 +
roadmap-parser + state + verify + health-validation suite staying green
(1260/1260) and the all-version-bearing/legacy fixtures showing no
behavior change.

TDD: tests/adr-612-bracket-phase-counting.test.cjs describe block
"#612 PR-2 B3: bracket boundaries engage even when CURRENT is
version-bearing but a sibling is not" — 4 tests, confirmed red against
pre-fix code (leak-in booleans true/true, total_phases 4) before this
change, green after.

* fix(#2761): reject same-milestone continuation headings as boundaries (B1)

Gate-2 adversarial review Blocker 1: the B1/B3 boundary fired on ANY
as the one currently selected — a version-less checklist/detail split
(`## [GSD.02] Foundation (Phase Details)`, or an ad-hoc continuation
heading) truncated the current milestone's own section instead of
being recognised as a continuation of it. The `(Phase Details)`
re-append only searches VERSION-STRING matches, so a version-less
continuation heading was cut out and never re-appended — a confidently
wrong, non-degraded phase count for a still-incomplete milestone
(repro8 case 1: 1/1/100 instead of 2/1/50; repro5: same, on a fully
version-less roadmap with no sibling milestones at all).

Introduces one shared helper, isBracketMilestoneBoundary(headingText,
level, selectedBracketId), used by both computeSectionEnd and the
preambleCutoff bracket scan, replacing the ungated `h.level <= 2 &&
bracketMilestoneHeadingRe.test(...)` inline check. `selectedBracketId`
(case-folded via phase-id.cts's foldBracketId, matching the branch's
own fold-before-identity convention) is derived from `selected[0]`,
which is the full matched heading line on BOTH selection paths
(version-string and bracket-fallback), so one extraction covers both.

Level cap stays at `level > 2` for now (temporary — ADR-612's content
discriminator replaces it in the next commit); same-milestone rejection
is the change this commit is scoped to.

DEVIATION from the reviewed plan, caught empirically: applying the
same-milestone rejection at the preambleCutoff site (as literally
specified) regressed an existing pin ("boundary heading level: a
level-1 CURRENT milestone heading also scopes correctly") and a
fenced-heading case (repro10 A3) — because preambleCutoff's job is
"where does the earliest milestone-shaped heading sit, scanning from
the TOP of the document," and the selected heading's own occurrence is
always a correct answer to that question regardless of same-id-ness;
rejecting it let the earliest-of-either comparison fall through to a
stray LATER heading instead. `selectedBracketId` is threaded through as
`null` at the preambleCutoff call site for this reason — bracket-shaped
(and, from the next commit, phase-tail) discrimination still applies
uniformly at both sites; only the same-milestone component is
call-site-specific, since it encodes a "keep scanning past this
heading" instruction with no counterpart in a top-of-document search.

Tests: new describe block "#612 PR-2 B1 round-2: a same-milestone
continuation heading is not a boundary" — RED-turned-GREEN fixtures for
repro8 case 1 and repro5, plus PINs for repro8 case 3 (trailing
different-id icebox still terminates) and repro10 A1 (all-version-
bearing + icebox + Phase Details stays exactly 2/1/50 — no double-count
from the same-milestone exclusion interacting with the pre-existing
detailsMatch re-append). syncedTotal()/syncedPercent() assertions
omitted from the repro10 A1 pin: that fixture carries dirs outside the
current milestone, which exposes the SEPARATE Major 1 defect
(cmdStateSync's body percent from an unfiltered disk scan) — asserted
once Major 1 is fixed, not here.

Full suite green (796/796 across the targeted adr-612 + roadmap-parser
+ state files); node scripts/lint-phase-id-drift.cjs clean; eslint
clean on both changed files.

* fix(#2761): bracket boundary discriminates by content, not heading level (B2)

Gate-2 adversarial review Blocker 2: three sites disagreed about which
heading levels are a bracket milestone. The selector
(roadmap-parser.cts's bracket-fallback SELECTION branch,
`^#{1,3}\s+\[CODE.MM\]`) and `isMilestoneBounded` (state.cts) both
admit level 1-3, but isBracketMilestoneBoundary's level cap only
admitted level 1-2 (`h.level <= 2`, from the B1 commit). A `###`-level
bracket milestone heading was therefore SELECTED and BOUNDED but never
TERMINATED: computeSectionEnd ran with level=3, a level-3 SIBLING
milestone survived the pre-existing `h.level > level` (not-deeper)
filter, failed the version/emoji test (version-less), then failed
`h.level <= 2` — falling through to `return content.length` and
sweeping the sibling milestone's own phases into the current one.
Reproduces trek-e's original #612 defect verbatim ("a safe degrade
became a confidently-wrong persisted number") on a heading level the
selector and bounding predicate both already admit (repro2 case C:
4/75% instead of 2/100%; mechanism confirmed directly via repro7 —
extractCurrentMilestone returned the whole 214-byte document).

ADR-612 Decision 1 (docs/adr/612-bracket-phase-id-convention.md:56)
specifies the discriminator as CONTENT, not level: "a phase heading is
a bracket followed by a digit-then-colon ([GSD.02] 05:); a milestone
heading is a bracket followed by a name." Replaces the `level > 2`
rejection with BRACKET_PHASE_TAIL_RE — built by interpolating
phase-id.cts's single-owner phaseHeadingPrefixSrcFor(ANY_BRACKET,
'bracket', false) plus the digit + optional-tag + colon tail every
phase-heading counter in this file already spells, not a re-typed
grammar — and widens the level check to a depth-sanity cap of 3
(mirroring the selector's own `#{1,3}` ceiling; NOT itself a
phase/milestone discriminator). Covers the dotted sub-phase heading
form (`[GSD.02] 05.03:`) via the same `[\w][\w.-]*` token, pinned by a
new fixture — the shape where a regex slip in the tail grammar would
hide.

preambleCutoff's own raw-scan regex is widened from `^(#{1,2})` to
`^(#{1,3})` in lockstep: the outer pattern's level ceiling must track
the helper's cap, or a level-3 PRIOR milestone heading is invisible to
that scan and its own phase heading leaks into the preamble
un-stripped (a real double-count this widening closes, verified
against repro2 case C directly).

The existing "boundary heading level: a level-3 CURRENT milestone
heading still scopes correctly" pin (3e562f12) now passes via a
DIFFERENT mechanism than before — its own neighbours are version-
bearing, so it previously passed via the version/emoji rule (the level
cap was never actually exercised by that fixture, per the round-2
review's own finding); with the content discriminator, the SAME
fixture's level-3 phase headings are now correctly excluded because
they are phase-tail-shaped, not because they are too deep. A
deliberate mechanism change, confirmed by re-running that test green
after this commit.

Also updates the "every selector call site declares the right
baseline" governance pin (adr-612-bracket-heading-selection.test.cjs):
BRACKET_PHASE_TAIL_RE is a new, legitimate ANY_BRACKET call site in
roadmap-parser.cts (always passing the literal 'bracket' convention,
since its only caller is already gated on bracketBoundaryActive) —
EXPECTED count bumped 1->2, with a matching BASE_SITES transcription
entry (identical src to every other ANY_BRACKET site, since the
function is pure).

Tests: new describe block "#612 PR-2 B2 round-2: the bracket boundary
is a CONTENT discriminator, not a level cap" — RED-turned-GREEN for
repro2 case C (exact total AND truthful percent, since
isMilestoneBounded already returns true at #{1,3}) and repro7's
mechanism, a PIN for the dotted sub-phase form, and a re-pin of repro8
case 3 (icebox) under the new mechanism.

Full suite green (907/907 across the targeted adr-612 + roadmap-parser
+ state + phase-id files); node scripts/lint-phase-id-drift.cjs clean;
eslint clean on all changed files.

* fix(#2761): fence-aware preamble cutoff on the bracket branch (Blocker 3)

Gate-2 adversarial review Blocker 3: preambleCutoff's bracket scan used
a raw content.match/matchAll — blind to fenced code blocks — while its
sibling computeSectionEnd (a few lines above it) already consumed
tokenizeHeadings(content), which strips fences. The two halves of one
boundary semantic disagreed about what a heading is.

A fenced markdown example in the preamble containing a bracket heading
(ADR-612's own docs do exactly this) was textually the earliest
`#{1,3} [CODE.MM]` match: preambleCutoff landed INSIDE the fence,
`preamble = content.slice(0, preambleCutoff)` ended with an unclosed
opener, and the unbalanced fence then blinded
getMilestonePhaseFilter's own tokenizeHeadings(scope) call — every
heading in the returned scope vanished, phaseCount degraded to 0, and
the pass-all filter admitted every directory on disk (repro11's
mechanism, confirmed directly: fence count 1/odd, tokenizeHeadings(scope)
-> only "Roadmap"). Regression vs round-1, which had no bracket pattern
to blind and so fell back to the correct heading (repro12 bracket row:
2/1/50 at round-1, 4/3/75 at HEAD).

Fixed by hoisting one tokenizeHeadings(content) call
(currentMilestoneHeadings) shared by computeSectionEnd and the
preambleCutoff scan, which now iterates that same fence-aware token
list instead of a raw regex. HeadingToken.text is already hash-stripped
and trimmed, so isBracketMilestoneBoundary needs no `^#{1,3}\s+`
re-derivation at this site (that spelling would not match h.text — a
note the round-2 review called out explicitly, confirmed while
porting). selectedBracketId stays `null` here, unchanged from the B1
commit's same-milestone-exclusion reasoning.

DISCLOSED, not fixed (explicitly out of scope per the round-2 review's
own minimal-fix note): the LEGACY (non-bracket) anyMilestonePattern
raw-match path shares the identical fence-blindness hazard and stays
byte-identical — a bracket repo whose preamble has a fenced
VERSION-BEARING heading still has the legacy raw-match win the
earliest-of-either min() (repro12's LEGACY control: 4/3/75, unchanged
across base/round-1/HEAD/this commit). Pinned here so a future reviewer
files this as a known, pre-existing gap rather than a new regression.

Tests: new describe block "#612 PR-2 Blocker 3 round-2: preambleCutoff
is fence-aware (bracket branch only)" — RED-turned-GREEN for repro12's
bracket row and repro11's mechanism (fence balance + non-degraded
phaseCount + correct per-directory admission), a PIN for repro12's
LEGACY control (the disclosed gap, explicitly unchanged), and a PIN for
repro10 A3 (a fenced heading INSIDE the current section must still not
terminate it).

Full suite green (1072/1072 across the targeted adr-612 + roadmap-
parser + state + phase-id + markdown-sectionizer files); node
scripts/lint-phase-id-drift.cjs clean; eslint clean.

* fix(#2761): scope cmdStateSync's disk scan by milestone under bracket (Major 1)

Gate-2 adversarial review Major 1: `state sync` wrote a Progress
PERCENT computed from an UNFILTERED whole-disk scan, beside the
milestone-scoped total_phases/completed_phases it writes into the same
STATE.md via the refreshed frontmatter (syncStateFrontmatter ->
buildStateFrontmatter, which has always applied getMilestonePhaseFilter
for the READ path). cmdStateSync's own `fs.readdirSync` chain (the
WRITE-path scan) never called the milestone filter at all, unlike
buildStateFrontmatter's identical-purpose scan. One command therefore
wrote two contradictory numbers into one file: on the ADR-canonical
version-less bracket fixture (4 dirs, 3 complete; asserted milestone =
2 phases, both complete), base wrote total_phases:2/completed_phases:2
(correct, from the READ derivation) alongside body Progress 75% (wrong
— from the unfiltered WRITE derivation; repro3).

Fixed by threading `getMilestonePhaseFilter(cwd)` through the same
`.filter()` chain buildStateFrontmatter already applies, gated on
`syncConvention === 'bracket'` (falling back to a pass-all predicate
otherwise) — so totalDiskPlans/totalDiskSummaries/diskCompletedPhases/
syncTotalPhases become milestone-scoped under bracket, byte-identical
under legacy.

DEVIATION (approved, stated plainly): an earlier phrasing of this fix
called for mirroring buildStateFrontmatter's filter UNCONDITIONALLY.
Implemented GATED instead — an unconditional filter would ALSO move
every LEGACY repo's persisted percent, since the milestone-scoping-vs-
whole-disk divergence this closes is engine-wide, not bracket-specific.
The gate keeps legacy byte-identical, which is the binding constraint:
this is a bracket read-path PR, not a legacy behavior change.

Nit 2 (informational, no code change): 10 calls to
extractCurrentMilestone on a legacy repo cost 10 config.json
existsSync + 10 readFileSync (0 before B3); accepted, unmemoized cost,
unaffected by this commit.

Also folds in two minors from the round-2 review:
- Corrects .changeset/2761-bracket-read-tolerance.md: the sibling-
  exclusion sentence now states it holds at any heading level 1-3 and
  across a milestone split over two headings (true again now that
  Blockers 1 and 2 are fixed); the percent sentence states plainly that
  `state sync`'s body percent is now milestone-scoped under bracket,
  and unaffected under legacy.
- Records the read/write scoping divergence at currentMilestoneRawRanges
  (src/roadmap-parser.cts) in a comment: it did not receive B1/B2's
  bracket boundary fixes, currently harmless (its only consumer falls
  back to whole-content mutation, and every mutation there is still
  Phase-labelled-only, not bracket-widened), but live the moment the
  write path is bracket-widened — flagged so a future PR closes it in
  lockstep with that work, not after.

Tests: 6 pre-existing tests in tests/adr-612-bracket-phase-counting.test.cjs
needed fixture updates, not logic changes — they used the default
single directory (`GSD.02-01-setup`, phase "01"), which the SENTINEL/
retirement/mixed-heading fixtures in those tests never declare as a
real phase (only 04/05/06/999/etc are declared). Before this fix,
cmdStateSync's unfiltered scan counted that off-roadmap directory
anyway; after this fix the milestone filter correctly excludes it,
which for several of these fixtures made `state sync` a no-op (the
computed 0% coincided with STATE.md's initial template default) and
broke `syncedTotal()`/`syncedPercent()`'s ability to observe anything.
Updated each to pass an EXPLICIT directory naming one of the fixture's
REAL declared phases, preserving each test's original numerator/
denominator intent. One test — "shape 2 WRITE" — was substantively
rewritten: it was a CHARACTERIZATION of the Major 1 bug itself ("the
DISCLOSED legacy gap, mirrored — not closed"), and now correctly pins
bracket closing to 33% (agrees with the read path) while legacy stays
at the disclosed 60% (unchanged, deliberately, per the gating decision
above).

Full suite green: `npm test` 1449/1449 (0 fail, 0 skipped, 0 todo,
single-shard "all" run — includes issue-2765-brace-expansion-lockfile
passing); `npm run lint:ci` clean (0 errors; 2 pre-existing timing-
assertion warnings in files this PR does not touch); node
scripts/lint-phase-id-drift.cjs clean; node scripts/changeset/lint.cjs
ok.

* fix(#2761): preambleCutoff identity is offset- and child-aware (round-3 Blocker 1)

Gate-2 round-3 re-verify Blocker 1 (NEW): the round-2 B1 deviation
(39c42a89) threaded `selectedBracketId` as the real value at
computeSectionEnd but as bare `null` at the preambleCutoff scan. The
deviation's rationale — "the selected heading's own occurrence is
always a correct earliest answer" — was right, but `null` disables the
same-milestone check for EVERY candidate, not just the selected one.
Any bracket-shaped heading earlier than the selected milestone was
accepted as a boundary regardless of identity: a same-id checklist/
overview heading preceding the version-bearing selected heading (cases
A, B — the version lands on the LATER half of a split, or a plain
overview heading with no "(Phase Details)" spelling), or a DIFFERENT-id
bracket-shaped PROSE heading with no children of its own sitting above
the current milestone's content (case D — `## [ADR.612] Heading
convention used by this roadmap`). In every case the region between
that false boundary and the real sectionStart was silently dropped —
a completed phase vanished and `state sync` persisted a confident 0%
where base and round-1 both correctly wrote 50%. Regression vs base
AND round-1 (not merely "under-fixed", per the round-3 review's own
severity note).

Fixed with two changes, both scoped to the preambleCutoff scan only
(computeSectionEnd already threads the real `selectedBracketId` and is
untouched):

(a) `h.offset === sectionStart` now bypasses BOTH the same-milestone
    check inside isBracketMilestoneBoundary (passing the REAL
    `selectedBracketId` for every other candidate) and the new child
    rule below — the selected heading's own position is definitionally
    the correct answer, so neither discriminator should run against it
    (rejecting it would mean rejecting the heading against ITSELF).
    Closes cases A and B — verified by the reviewer's own one-liner,
    reproduced here.

(b) New `bracketHeadingHasMatchingChild`: an otherwise-accepted
    candidate (bracket-shaped, not phase-tail-shaped, not the same id
    as the selected milestone) must ALSO have a next-strictly-deeper
    heading carrying its OWN bracket id to count as a boundary. This is
    what a genuine sibling milestone has (its own phase children share
    its bracket id — `## [GSD.01] Setup` / `### [GSD.01] 01: …`) and an
    unrelated bracket-shaped prose heading does not. A candidate with
    no such child at all (childless — e.g. an empty prior milestone, or
    one immediately followed by a same-or-shallower heading) degrades
    to NOT a boundary — over-inclusive, the safe direction: its own
    heading text stays in the preamble, contributing nothing to any
    phase count (not phase-shaped). Closes case D, which (a) alone does
    not — verified: without this rule, `[ADR.612]`'s prose heading is
    indistinguishable from a genuine prior sibling at this site.

As a side effect, also neutralizes Nit 2 (a colon-less `[GSD.02] 05`
heading spuriously terminating the preamble): a colon-less bracket
heading is not phase-tail-shaped so isBracketMilestoneBoundary alone
would accept it, but it is — precisely because it is malformed/
incomplete rather than a real milestone — childless, so the child rule
rejects it too. Pinned.

Known interaction with the fence-blind SELECTION path (disclosed by
the reviewer, not introduced here, tracked for the next commit): when
`sectionPattern` selects a FENCED version-bearing heading (an
extremely pathological shape — a fenced example whose text happens to
match STATE's asserted version), no token exists at `sectionStart`, so
the `h.offset === sectionStart` bypass never fires and the loop falls
through to the ordinary same-id / child-rule checks. This composes
with the round-3 Major 1 fix (next commit) rather than introducing a
new defect — SELECTION itself is untouched by any of this — but is
worth stating plainly rather than rediscovering.

Tests: new describe block "#612 PR-2 Blocker 1 round-3: preambleCutoff
identity is offset- and child-aware" — RED-turned-GREEN for cases A, B
(rv-attack1) and D (rv-attack1b) with syncedTotal()/syncedPercent()
assertions (the persisted 0% is the point), a PIN for a genuine prior
sibling with real children (still excluded), a PIN for a childless
prior sibling (degrades to not-cutting, over-inclusive/safe), a PIN
for the colon-less Nit 2 shape, and the reviewer's rv-mech1 mechanism
re-run as a proper test (scope now equals the full input document,
phaseCount 2, both dirs accepted).

* fix(#2761): fence-aware version/emoji half of preambleCutoff on the bracket branch (round-3 Major 1)

Gate-2 round-3 re-verify Major 1 (NEW): ff6bf0a8 (round-2 Blocker 3)
made the BRACKET half of preambleCutoff's "earliest milestone-shaped
heading" search fence-aware, but left the VERSION/emoji half a raw
`content.match` even on the bracket branch. A fenced VERSION-BEARING
example heading in a bracket repo's preamble (ADR-612's own docs
illustrate the LEGACY heading shape exactly this way, inside a fenced
authoring-guide block) was still textually the earliest match for that
raw regex, winning the min() and un-suppressing a wrong persisted 75%
that base correctly suppressed (rv-attack3c fixture C1: base
suppressed the percent entirely — `isMilestoneBounded` false — HEAD
wrote 75% where truth is 50%).

Fixed by deriving the version/emoji half from the SAME fence-aware
`currentMilestoneHeadings` token list as the bracket half, on the
bracket branch only — the exact `/^Phase\s+\S/i` / `/v\d+\.\d+|✅|📋|🚧/i`
pair `computeSectionEnd` already uses against `h.text`. The non-bracket
(legacy) path is untouched: it keeps the raw `content.match`, byte-
identical to before, including its own fence-blindness (repro12's
LEGACY control, pinned unchanged in the round-2 Blocker-3 test block —
not re-pinned here to avoid duplicating an already-covered assertion).

Not rated Blocker (per the review) because it is not a regression vs
round-1 and the fixture (a version-BEARING fenced example in a bracket
repo) is rarer than the already-fixed bracket-heading case; still
fixed now rather than disclosed, per this arc's own precedent (every
prior "disclose instead of fix" call in this PR has been overturned on
re-review).

Tests: new describe block "#612 PR-2 Major 1 round-3: preambleCutoff's
version/emoji half is fence-aware on the bracket branch" — RED-turned-
GREEN for case C1 (readTotal + syncedPercent, so the persisted 75% is

* chore(#2761): correct changeset claims + mark runtime-gated BASE_SITES row (round-3 minors)

Gate-2 round-3 re-verify Minor 2: three changeset sentences in
.changeset/2761-bracket-read-tolerance.md were overstated in a new
direction after round-2:

- The split-milestone claim ("across a milestone split over two
  headings") was true only when the version-bearing heading came
  FIRST (repro8 case 1); false when it came LATER (round-3 Blocker 1
  case A). Now restated to say plainly "with the version-bearing
  heading in EITHER position" — true again now that round-3's Blocker
  1 fix lands earlier in this range.
- The "counted from the phases... rather than from every directory on
  disk" claim was false on cases A/B/D (a strict subset of the
  milestone's own phases). Restated as "ALL of the phases... not a
  subset", and extended to state that an unrelated bracket-shaped
  heading with no phase children of its own (case D's `[ADR.612]`
  shape) does not truncate the milestone either — true now, not before.
- "Each widened read is SELECTED by the project's phase_id_convention"
  was literally false for BRACKET_PHASE_TAIL_RE, which is RUNTIME-gated
  (via its only caller, isBracketMilestoneBoundary, itself only
  consulted when bracketBoundaryActive) rather than selector-gated.
  Restated behaviourally: "every widened read ENGAGES only when the
  project's resolved phase_id_convention is bracket" — true for both
  gating mechanisms, so it no longer implies a selector call this site
  does not make.

Minor 1: the STRUCTURAL IDENTITY test's BASE_SITES row for
BRACKET_PHASE_TAIL_RE (added in the B2 commit) asserts a property of
`phaseHeadingPrefixSrcFor` — the function — not of the call site; it
would pass unchanged even if the site were deleted. Safety at that
specific site rests entirely on a runtime gate the test cannot see.
Added `runtimeGated: true` to the row and threaded it into the
generated test's own title (`… [runtime-gated, not selector-covered]`),
so the gating mechanism is visible in test OUTPUT, not only in a source
comment that could drift silently.

No production code changed. Targeted suite green (48/48 in the
affected file); `node scripts/changeset/lint.cjs` ok; eslint clean.

* fix(#2761): harden round-3 preamble cutoff — subtree child scan + level cap

Team-lead review of f87bba0e found two edges in the round-3 preamble-
cutoff code, both hardened here.

AMENDMENT 1 — bracketHeadingHasMatchingChild (2e06aef5) checked only
`headings[index + 1]`, the IMMEDIATE next heading, not the candidate's
whole subtree. A genuine prior sibling milestone whose section opens
with a non-bracket subsection before its first phase heading
(`## [GSD.01] Setup` / `### Notes` / `### [GSD.01] 01: Old`) was
therefore wrongly rejected as a boundary — its real phase heading sits
TWO headings deep, not one — leaking its entire section into the
preamble unstripped.

CONFIRMED RED, not merely theoretical (built and ran the fixture
against f87bba0e before touching the fix, per instruction): scope
membership DOES drive the disk-side filter on this shape.
`GSD.01-01-old`'s directory was wrongly admitted into the CURRENT
milestone's filter via the leaked heading's qualified key
(`GSD.01-01`) — 3/2/67% where truth is 2/1/50%.

Fixed by scanning the candidate's full SUBTREE: continue past a
non-matching deeper heading instead of returning false on the first
one; only a same-or-shallower heading actually closes the subtree and
yields "no match found". A candidate whose entire subtree closes with
no same-id hit (including a genuinely childless one) still degrades to
`false` — over-inclusive, safe, unchanged from before.

AMENDMENT 2 — c483552a ported the version/emoji half of preambleCutoff
to the token-based scan with no level cap; the raw
`content.match(anyMilestonePattern)` it replaced was anchored
`^#{1,3}\s+`. A level-4+ version-bearing heading in the preamble
(`#### v2.0 notes`) therefore won the scan on the bracket branch where
the raw pattern — and the legacy path, unaffected — ignores it
outright. Fixed with `if (h.level > 3) continue;`, mirroring the
depth-sanity cap isBracketMilestoneBoundary already applies to the
bracket half of this same scan.

Tests: new describe block "#612 PR-2 round-3 hardening: subtree child
scan + level cap on preambleCutoff" —
- RED-turned-GREEN for the Notes-intervening fixture: exact 2/1/50 (was
  3/2/67), plus the disk-filter observable (`GSD.01-01-old` now
  correctly excluded).
- PIN for the level-4 preamble heading: the scope now PRESERVES the
  heading's text (was silently dropped before this fix — harmless in
  this minimal fixture's total_phases specifically, since the dropped
  text carries no phase-shaped content, but a real correctness gap
  against the raw pattern's own ceiling) — asserted via scope content,
  not total_phases, since that number is invariant here either way.
- PIN for the LEGACY control on the same level-4 shape — unchanged,
  confirming the raw content.match path is untouched.

Re-verified the existing genuine-prior-sibling and childless-sibling
pins (round-3 Blocker 1 commit) still pass under the subtree scan —
both fixtures' outcomes are unchanged since their same-id hit (or its
absence) was already at the first deeper heading.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`

lint:ci` deferred to the team lead's own run per instruction.

* fix(#2761): bracketHeadingHasMatchingChild requires a same-id PHASE child (round-4 Blocker 1)

Gate-2 round-4 re-verify Blocker 1 (NEW): the round-3 hardening's
subtree scan (fbfd0fca) proved SAME-ID-NESS but never asked whether
the matching child was PHASE-shaped. Case F1 re-opens round-3's case D
one heading later: `## [ADR.612] Heading convention` is followed by
its OWN sub-heading `### [ADR.612] Examples` — same bracket id as the
candidate, but MILESTONE-shaped (a name, no digit-then-colon), not a
phase. Same-id-ness alone satisfied the subtree scan and re-cut the
preamble at exactly the shape the round-3 hardening was written to
close.

Failing input: `## [ADR.612] Heading convention` / `### [ADR.612]
Examples` (prose) / `### [GSD.02] 01: One` (the current milestone's
own first phase, now unreachable) / `## [GSD.02] v2.0: Foundation` /
`### [GSD.02] 02: Two`. Truth 2/1/50. HEAD read 1/0/0, and `state sync`
reported "nothing to do" (exit 0, `{synced:true,changes:[]}`) because
its wrong 0% happened to equal the STATE.md seed — a half-done
milestone read as untouched with no write-path signal at all.

Fixed with the reviewer's one-conjunct addition: a same-id child only
counts if it is ALSO phase-tail-shaped (`BRACKET_PHASE_TAIL_RE`) — the
same single-owner discriminator `isBracketMilestoneBoundary` already
uses one level up for the identical distinction (phase vs milestone),
reused here rather than re-derived. This is exactly what the
changeset's own wording already claimed ("no phase children of its
own") — the code now matches the sentence rather than the other way
around.

Docstring updated at the function itself: the rule is "same-id PHASE
child", not "same-id child".

Tests: new describe block "#612 PR-2 round-4 Blocker 1: the same-id
child must be PHASE-shaped" — RED-turned-GREEN for F1 with
syncedTotal()/syncedPercent() (the persisted 0% — and the
report-nothing-to-do write-path silence — is the point), PINs for F11
(colon-less same-id child) and F11b (bullet-only phase list): both
correctly stay excluded either way, and the leak the phase-shape
requirement newly creates for these two shapes is INERT — a colon-less
heading forms no qualified key (getMilestonePhaseFilter's own
phase-heading pattern requires the colon too) and a bracket bullet
never matches the legacy-only BULLET_PHASE_LINE_PATTERN — confirmed
directly via getMilestonePhaseFilter, not merely inferred. Re-verified
the four existing child-rule pins (F2 subtree-closure, F3 deep-nested
same-id, F4 level-4 same-id, F5 childless-at-EOF) are unaffected by the
phase-shape requirement, since every one of them already used a
colon-bearing same-id child.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 946/946 pass (942 + 4 new). Zero drift measured across the full F1-F12
corpus except F1 itself (F9/F10/F12 remain red, deferred to the
separate Major 1 fix). node scripts/lint-phase-id-drift.cjs clean;
eslint clean on both changed files.

* fix(#2761): fence-aware phase counting, milestone bounding, and bracket-fallback selection (round-4 Major 1)

Gate-2 round-4 re-verify Major 1 (NEW): roadmapPhaseCount is a
fence-blind raw `.exec()` over the scope string, duplicated in TWO
independent copies (buildStateFrontmatter's read path, cmdStateSync's
write path). With the bracket alternative now compiled into it (#612),
a fenced EXAMPLE phase heading in the preamble inflates total_phases
and persists a wrong percent that base got right. Two further
fence-blind sites participate: isMilestoneBounded (a raw
`.test(roadmapRaw)`) and the bracket-fallback SELECTOR inside
extractCurrentMilestone (a raw `content.matchAll`, only reachable when
version-string selection finds nothing).

Failing inputs:
- F10 (clean isolate, version-bearing selection): a fenced
  `### [GSD.02] 05: Example phase` in the preamble inflates
  total_phases 2->3, persisting 33% where truth is 50%. LEGACY control
  on the same shape is correct on every build — not a pre-existing
  hazard being inherited, bracket-only.
- F9 (version-less selection): a fenced example carrying the project's
  OWN milestone id additionally confuses the bracket-fallback selector
  (the fenced heading gets SELECTED), compounding with the same
  fence-blind counter. base suppressed the percent; round-1 and HEAD
  both wrote 33%.
- F12 (isMilestoneBounded isolate): the ONLY `[GSD.02]` heading in the
  document is inside a fence, and the asserted milestone genuinely has
  no section at all — HEAD persisted 67% where base correctly
  suppressed the percent (the milestone is absent from the roadmap).

Fixed at the CONSUMER level, not the producer — extractCurrentMilestone's
returned scope string is deliberately UNCHANGED, since every other
consumer of that string needs its full content fidelity and legacy
identity forbids touching the shared string (this branch's own
precedent, ff6bf0a8/c483552a, was producer-level; here the ruling is
consumer-level because the string is shared far more broadly than the
two round-3 fixes' narrower producer edits):

(a) New `countRoadmapPhaseHeadings` (src/state.cts, immediately above
    extractRetiredPhaseNumbers) — ONE shared implementation for both
    call sites, replacing two independently-maintained copies. BRACKET
    convention counts via `tokenizeHeadings(scope)` at levels 2-4,
    testing each heading's hash-stripped text directly — fence-aware by
    construction, since tokenizeHeadings never produces a token for a
    fenced line. LEGACY convention keeps the exact pre-existing raw
    `.exec()` loop, byte-for-byte. A pre-existing, deliberately
    PRESERVED asymmetry between the two original call sites — the read
    path always excluded a bare `/^999\b/` token, the write path never
    did — is threaded through as an explicit
    `includeUnconditional999Check` parameter per call site, so sharing
    the implementation does not silently unify (and thereby move)
    either total.
(b) isMilestoneBounded's bracket branch now scans
    `tokenizeHeadings(roadmapRaw)` for a matching heading (level <= 3)
    instead of a raw regex test. Legacy version-string branch untouched.
(c) The bracket-fallback SELECTOR now builds its candidate set from
    `tokenizeHeadings(content)` instead of `content.matchAll`,
    reconstructing a match-shaped array so every downstream consumer of
    `headingMatches` sees the identical shape the raw-regex path always
    produced. This is the ONE site in this entire arc where SELECTION
    itself changes — selection SEMANTICS are otherwise unchanged (same
    pattern, same first-match-wins by document order); only the
    candidate set is now fence-aware. Pinned that unfenced selection is
    byte-identical.

Zero drift measured across the full historical corpus (repro2-13,
rv-attack1/1b/3c, rv-mech1, rv2-amend1/2, and F1-F11b) except the three
target fixtures.

Tests: new describe block "#612 PR-2 round-4 Major 1: four fence-blind
sites on the bracket path" — RED-turned-GREEN for F10 (with
syncedTotal()/syncedPercent()) and F9 (both layers), PINs for F10's
LEGACY control and F10c (non-phase-shaped fence, unaffected either
way), RED-turned-GREEN for F12 (asserts the percent KEY is absent from
`state json`'s output and that `state sync`'s body stays at its
unmodified seed — the persisted-suppression signal, not merely a
total_phases number), and an explicit PIN that unfenced bracket-fallback
selection (first real milestone-shaped heading wins, no fences
involved) is unaffected.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* chore(#2761): correct docstring overstatement + stale consumer-count sentence (round-4 minors)

Gate-2 round-4 re-verify Minor 1 + Nit 1. No production code changed.

Minor 1: bracketHeadingHasMatchingChild's own docstring said a
rejected (no-same-id-PHASE-child) candidate's degrade "contributes
nothing to any phase count" — true of the candidate's OWN heading
text, but not of its SUBTREE, which is what actually stays in the
preamble. F7 (`## [GSD.01] Setup` / `### [GSD.07] 01: Foreign`) shows
a DIFFERENT-id bracket PHASE heading inside a rejected candidate's
subtree DOES form a qualified key and CAN admit a foreign directory —
3/2/67%, stable across base, round-1 and HEAD (base via its own
pass-all degrade). Not a regression, still the declared over-inclusive
/ never-under-inclusive safe direction — the comment now says that,
with F7's numbers cited, at the call site that actually decides
`isBoundary` (roadmap-parser.cts's preambleCutoff loop) rather than
only at the helper's own definition.

Minor 2 (changeset) — VERIFIED, no wording change needed: re-ran F1,
F9, F10, F12 at this HEAD. The "no phase children of its own... does
not truncate it either" sentence (naming the `[ADR.612]` shape
directly) is now literally true — F1 reads 2/1/50. The "counted from
ALL of the phases... not a subset" sentence is now true on every
measured shape — F1/F9/F10 all read 2/1/50, F12 correctly suppresses
the percent. No carve-out for F9/F10 is needed since round-4 Major 1
(3be5c412) closes both; per the fix-round instruction to "only carve
out anything genuinely left," nothing is.

Nit 1: tests/adr-612-bracket-heading-selection.test.cjs's runtimeGated
row claimed `BRACKET_HEADING_INTRO_RE` has "no other consumers" — true
when round-3's f87bba0e wrote it, stale since 2e06aef5 (round-3's own
earlier commit) had already added two more uses inside
bracketHeadingHasMatchingChild. Corrected to state the true count
(three consumers) and re-confirm the conclusion is unaffected: all
three are still nested inside the same bracketBoundaryActive runtime
gate, and BRACKET_HEADING_INTRO_RE is built from BRACKET_ID_SRC, not
phaseHeadingPrefixSrcFor, so it was never a selector site regardless of
consumer count.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 952/952 pass (comment-only changes, no count movement). eslint

* fix(#2761): restore the bracketId guard in countRoadmapPhaseHeadings (round-5 Blocker 1)

Gate-2 round-5 re-verify Blocker 1 (NEW, introduced by 3be5c412): the
merge that created the shared countRoadmapPhaseHeadings helper dropped
the `bracketId && ` guard both original inline loops carried before
calling isSentinelPhaseId. Every other isSentinelPhaseId call site in
src/ (roadmap-parser.cts, roadmap.cts, validate.cts x2, verify.cts)
keeps the guard; state.cts's shared counter was the only one of seven
without it.

When the phase-heading-intro grammar's LEGACY alternative matches (a
`### Phase 00:` heading in a `phase_id_convention: "bracket"` repo —
the mid-migration shape this PR exists for), the bracket capture group
is `undefined`, so the unguarded call became
`isSentinelPhaseId("undefined-00", 'bracket')` — measured TRUE, so
phase 00 (and 000, 0a, 0.5, 999.1 — any token whose splice with the
literal string "undefined" happens to fall in a sentinel range) was
silently dropped from the denominator. `getMilestonePhaseFilter` (which
still carries its own guard) counts the phase and admits its directory
regardless, so the filter and the counter disagree — a half-done
milestone reads as 100% complete, persisted.

One-line fix, restoring the guard every sibling call site already has:

    if (bracketId && isSentinelPhaseId(`${bracketId}-${token}`, 'bracket')) continue;

Line count: `git diff --stat src/state.cts` -> 1 file changed, 1
insertion(+), 1 deletion(-).

Tests: new describe block "#612 PR-2 round-5 Blocker 1:

GREEN for G3 (3/2/67, was 2/2/100) and G3d (the mixed bracket+legacy
mid-migration shape, same numbers) with syncedTotal()/syncedPercent(),
PIN for G3's legacy control (unaffected), PIN for G3b (isolates the
counter with no directory to admit), PIN for G3c (legacy 01/02 only,
no sentinel-shaped token present).

* fix(#2761): extractRetiredPhaseNumbers is fence-aware on the bracket path (round-5 Major 1)

Gate-2 round-5 re-verify Major 1 (NEW) — a FIFTH fence-blind site on
the bracket path, missed by 3be5c412's own enumeration of "four".
extractRetiredPhaseNumbers' line scan (`scope.split(/\r?\n/)`) has no
fence awareness. This PR compiles the bracket alternative into
`introSrc` ("the retirement filter has to widen with the counter it
protects" — the function's own pre-existing comment), so a FENCED
authoring EXAMPLE showing the #1514 retirement gesture in bracket
spelling is now indistinguishable from a real one: it retires a
genuine phase, shrinking the denominator and persisting a confident
100% where base correctly read 50%.

Fixed with the SAME consumer-level ruling this arc has used at every
other fence-blind site, reusing markdown-sectionizer's existing
exported `stripFencedCode` rather than hand-rolling a second fence
parser (single-owner rule) — retirement lines are BULLETS, not
headings, so `tokenizeHeadings` doesn't serve here; `stripFencedCode`
is the general-purpose fence stripper the tokenizer itself is built on.
Gated on `convention === 'bracket'`; the LEGACY line scan stays the raw
`scope` string, byte-identical — its own fenced-example hazard is
pre-existing (wrong at base too) and out of scope.

Line count: `git diff --stat src/state.cts` -> 1 file changed, 9
insertions(+), 2 deletions(-) — one import added, four lines inside
the function (a comment + the `scanScope` computation + the changed
`.split()` call).

Tests: new describe block "#612 PR-2 round-5 Major 1:
extractRetiredPhaseNumbers is fence-aware on the bracket path" —
RED-turned-GREEN for G2 (fenced example in the preamble) and G2b (the
same example placed INSIDE the milestone section, ruling out a
preamble-scoping artifact — the site itself was fence-blind wherever
the fence sits), PIN for the LEGACY control (unchanged, pre-existing,
out of scope — base is wrong on this shape too).

Also folds in the "four fence-blind sites" correction: 3be5c412's
commit message and any restatement of it should read FIVE going
forward; this commit's own message states the count correctly.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): state sync's counter excludes the bracket 999 icebox token (round-5 Major 2)

Gate-2 round-5 re-verify Major 2 (NEW) — `includeUnconditional999Check`
left `state json` and `state sync` reporting different totals for one
bracket repo. Under bracket, READING-B puts the sentinel in the
bracket, so `isSentinelPhaseId("GSD.02-999", 'bracket')` is false —
the `/^999\b/` TOKEN rule is the only thing excluding a
`### [GSD.02] 999:` icebox heading, and it ran on the read path
(buildStateFrontmatter, `true`) and on getMilestonePhaseFilter
(unconditional), but not on cmdStateSync's own counter (`false`). One
`state sync` call could leave a single STATE.md with its own
frontmatter (percent 50, from the read-path re-sync inside
writeStateMd) and body (percent 33, from the write-path counter that
alone still counted the icebox heading) disagreeing — falsifying this
PR's own stated invariant that sharing countRoadmapPhaseHeadings made
"the two counters must see the same phases" structural.

Functional change is one argument, exactly as specified: the write
call site now passes `syncConvention === 'bracket'` instead of the
literal `false`. `syncConvention === 'bracket'` is `false` for every
non-bracket value, so the LEGACY path resolves to the exact same
`false` it always did — this file's own pre-existing, deliberately-
unchanged read/write divergence on that path is untouched. The READ
site (`:1860`) is NOT touched — its historical behaviour applied
`/^999\b/` to legacy and bracket alike, so changing it would move
legacy READ totals, exactly the class of mistake this arc's own
Blocker 1 (this round) was.

Line count: the functional change is ONE argument
(`false` -> `syncConvention === 'bracket'`); the surrounding comment
was rewritten because the previous one asserted the now-superseded
behaviour ("preserving this file's pre-existing... divergence... a
bare 999 token is not excluded here") and leaving it would mislead the
next reader — not a structural change.

Tests: new describe block "#612 PR-2 round-5 Major 2: state sync
excludes the bracket 999 icebox token like the read path" —
RED-turned-GREEN for G1, asserting `state sync`'s body percent equals
`state json`'s own percent (both 50, not 33 vs 50), PIN for G1's
legacy control (33 vs 50 unchanged, deliberately).

* chore(#2761): restore indent parity at the two line-start-anchored bracket-heading reconstructions (round-5 Minor 1)

`HeadingToken.offset` (tokenizeHeadings) is the LINE-START character offset,
not necessarily the `#` character's own offset — a ≤3-space-indented ATX
heading has both. Two round-4 reconstructions built on tokenizeHeadings
inherited this gap and accepted indented headings their raw, line-start-
anchored predecessors (`^#{1,3}\s+\[...`) never matched:

  1. roadmap-parser.cts's bracket-fallback SELECTOR (extractCurrentMilestone,
     ~line 377) — an indented, version-less `[GSD.02]` milestone heading
     could be reconstructed into headingMatches, then mis-parsed downstream
     (selectedBracketId null, level fallback to 1), leaking a SIBLING
     milestone's phases into the counted scope (G6: HEAD read 3/2/67 instead
     of 2/1/50 — a real phase heading's own directory belonging to the NEXT
     milestone got counted).

  2. state.cts's isMilestoneBounded (~line 1571) — the same gap let an
     indented-only `[GSD.02]`-shaped heading wrongly bound a milestone
     absent from the roadmap, un-suppressing a percent that should stay
     suppressed (mirrors round-4's F12 fenced-only case, but via indentation
     instead of a fence).

Fix: one added conjunct per site — `content[h.offset] === '#'` (source-named
`roadmapRaw` in state.cts) — filtering to tokens whose LINE-START offset IS
the `#` character, i.e. exactly the set the raw line-start-anchored regex
would ever have matched. Restores byte-for-byte raw parity; no other logic
in either function changes. computeSectionEnd and the preamble version/
emoji-token scan are untouched, as instructed — they consumed tokenizeHeadings
output before this arc and are out of scope here.

Also corrects roadmap-parser.cts's now-provably-false docstring claim that
`h.offset` is unconditionally "the same `#`-character coordinate space
`content.match().index` used" — true only for the survivors of the new
filter, not for every token tokenizeHeadings produces.

Line count: the FUNCTIONAL change is exactly 2 lines (one added `&&` conjunct
per call site — `git diff --stat` on the two source files shows 20
insertions/7 deletions, but only those 2 lines change behavior; the rest is
docstring/comment rationale, per this round's "state the line count" ask).

TDD: both fixtures verified RED at HEAD before this commit, GREEN after,
via /tmp/pr612rev/rv5-attack.cjs G6 and a locally-authored isMilestoneBounded-
isolating probe (G6 alone doesn't distinguish the two sites — its unindented
phase headings already satisfy isMilestoneBounded's loose prefix regex
either way, so a second, indentation-only fixture was needed to prove that
site's fix is not a no-op; verified by temporarily reverting just that one
conjunct, confirming 100%-wrongly-bounded RED, then restoring it, confirming
suppressed-percent GREEN).

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (G6): indented version-less bracket milestone heading — 2/1/50, not
    the pinned-before-fix 3/2/67.
  - PIN (G6c unindented control): identical document, no indent — 2/1/50
    unaffected on every build.
  - RED (isMilestoneBounded site, indented-ONLY): mirrors round-4's F12
    shape (fenced-ONLY → indented-ONLY) — percent stays suppressed instead
    of the pinned-before-fix wrongly-bounded 100%.

Full G1-G10 (rv5-attack.cjs) + G2b/G3c/G3d/G6c (rv5b.cjs) re-verified
zero-drift against TRUTH after this change. Targeted suite (adr-612-*,
roadmap-parser, state, verify): 962 -> 965 (+3), 0 fail.

* chore(#2761): changeset discloses counting-set narrowing + correct stale consumer-count sentence (round-5 minors)

FIX 5 (Minor 2): .changeset/2761-bracket-read-tolerance.md did not disclose
that bracket phase-heading counting is narrower than the raw-regex
predecessor in two ways the review's G4/G5 fixtures surfaced: a level-5
heading (`##### [GSD.02] 05: ...`) is no longer counted (the counter's
tokenizeHeadings scan caps at level 4, matching the selector/isMilestoneBounded
ceiling), and a space-less heading (`###[GSD.02] 05: ...`) is no longer
counted (CommonMark requires ≥1 space/tab after the hashes, which
tokenizeHeadings correctly enforces and the old raw regex did not). Both
G4 and G5 moved from round-1's wrong (inflated) values back to base's
original values as an incidental side effect of routing through
tokenizeHeadings — never a deliberate feature of this PR, and previously
undocumented. One clause added to the existing run-on paragraph; no other
wording in the changeset touched.

FIX 6 (Nit 1): tests/adr-612-bracket-heading-selection.test.cjs:76 —
`BRACKET_PHASE_TAIL_RE` has TWO consumers as of round-4's 65d257ce
(isBracketMilestoneBoundary's own use, plus bracketHeadingHasMatchingChild's
same-id-PHASE-child conjunct), not the "no other consumers" the comment
claimed. Same correction pattern round-4 already applied to this row's
BRACKET_HEADING_INTRO_RE neighbor (that sentence's own staleness was fixed
in 4d7184b8): note the true consumer count, confirm both stay nested inside

* fix(#2761): restore the bracketId guard on the bracket-only /^0\b/ sibling rule (round-6 Blocker 1)

Round-5's Blocker 1 was `isSentinelPhaseId("undefined-00")` — the merge
that introduced the shared counter dropped the `bracketId &&` guard on the
sentinel check. This is the identical failure one line further down, in the
sibling rule this PR itself added: when the phase-heading grammar's LEGACY
alternative matches (`### Phase 0:` in a `phase_id_convention: "bracket"`
repo — the mid-migration shape this PR exists for), `bracketId` is
`undefined`, and the unguarded `/^0\b/` fires on the bare token anyway.
Neither the LEGACY branch of this same function nor
`getMilestonePhaseFilter` has a `/^0\b/` rule at all, so the filter counts
the phase and admits its completed directory while the counter refuses to
count its heading — a milestone with an unstarted phase 02 persists as a
confident 100%.

`/^0\b/` matches `0` and `0.5` (word boundary before the `.`) but not `00`
(no boundary between the two zeros), which is exactly why round-5's G3/G3d
fixtures (`### Phase 00:`) never tripped this one — same defect class,
different token spelling.

Fix: one word, mirroring the guard round 5 restored two lines above —
`if (/^0\b/.test(token)) continue;` -> `if (bracketId && /^0\b/.test(token)) continue;`.

Expected and intentional side effect: `roadmap analyze` and `state json`
now disagree again on this bracket-repo shape (analyze phase_count=2, json
total_phases=3) — exactly as they already do under the legacy convention
today (verified via /tmp/pr612rev/rv6c.cjs on both conventions). That is
the counter regaining agreement with `getMilestonePhaseFilter` (the tighter
constraint — it is what actually decides `completed_phases`), not a new
break; the counter/filter disagreement is what was wrong.

Out of scope, deliberately NOT fixed here (Minor 1, disclosed via a PIN
test only): the bracket-SPELLED `### [GSD.02] 0:` shape has the same
counter/filter disagreement, but reads 2/2/100 on base too — never closed
by any build in this arc, so it is a pre-existing gap rather than a
regression this commit could introduce.

Line count: src/state.cts is exactly 1 insertion / 1 deletion (one word,
`bracketId && ` prepended to the existing condition).

TDD: T0 (`Phase 0:`) and T05 (`Phase 0.5:`) verified RED at HEAD before this
commit (json 2/2/100, sync body 100%) via /tmp/pr612rev/rv6b.cjs, GREEN
after (3/2/67 on both derivations, matching TRUTH). Zero-drift verified by
diffing the FULL corpus (rv5-attack, rv5b, rv4-attack, rv-attack1,
rv-attack1b, rv-attack3c, rv-mech1, rv2-amend1, rv2-amend2, rv6-attack
H1-H19, rv6b) between a pre-fix and post-fix build: the only differing
lines in the entire diff are T0, T05, and H14 — the three target fixtures.

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (T0) + PIN (T0L legacy control)
  - RED (T05) + PIN (T05L legacy control)
  - PIN (B0, bracket-spelled `0` — base-parity characterization, Minor 1,
    not fixed this round)
  Round-5's own G3 test (`### Phase 00:`) already serves as the T00 pin —
  `/^0\b/` never matched `00`, so it is unaffected and untouched.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 965 -> 970 (+5),
0 fail. `lint-phase-id-drift.cjs` and `npx eslint` on touched files clean.

* chore(#2761): changeset re-attributes the phase-count level cap + discloses the bare-0 carve-out; correct two stale test comments (round-6 Minor 1 + Nits)

FIX 2 (Minor 1 — disclosure only, NOT a code fix): the bracket-SPELLED
`### [GSD.02] 0:` / `0.5:` shape has the same counter/filter disagreement
round-6's Blocker fixed for the legacy spelling, but it reads 2/2/100 on
BASE too — never closed by any build in this arc, so it is a pre-existing
gap rather than a regression this round could introduce. Two changes:

  - Pinned as a base-parity characterization: new PIN test (B0) in
    04b5a95f's describe block asserting the exact unchanged value with a
    comment stating why it's deliberately not touched.
  - .changeset/2761-bracket-read-tolerance.md: one qualifying clause added
    to the "counted from ALL of the phases … not a subset" sentence — a
    bare `0`/`0.x` phase token (however spelled) keeps `roadmap analyze`'s
    own pre-existing sentinel reading under bracket too, so it stays
    excluded from these counts. Carried over, not newly introduced by this
    PR — `roadmap analyze` has always read it this way.

FIX 3(a) — same changeset paragraph misattributed the phase counter's
2-4 level cap to "the milestone-boundary machinery in this PR" (the
selector, `isMilestoneBounded`, the preamble scan) — that machinery caps
at `###` (level ≤3), not 2-4. The 2-4 cap belongs to
`getMilestonePhaseFilter`'s own phase scan. Re-pointed the attribution;
the paragraph's earlier, correct ≤3 claim (selector/isMilestoneBounded)
is untouched.

FIX 3(b) — tests/adr-612-bracket-heading-selection.test.cjs:76-82 (added by
1395bd89, round-5's own Nit-1 correction) claimed both
`BRACKET_PHASE_TAIL_RE` consumers are reached "only through the
`if (bracketBoundaryActive)` block starting at :529". Verified at HEAD:
`bracketHeadingHasMatchingChild` is (only caller :593, inside that block).
`isBracketMilestoneBoundary` is not — it has two callers, an inline
`bracketBoundaryActive &&` conjunct at `:473` (inside `computeSectionEnd`)
and the `:529` block at `:567` — the very fact this row's own earlier
"exactly two callers" paragraph already stated correctly. Corrected the
mechanism claim; the CONCLUSION (every consumer is still gated on the same
flag) is unchanged, exactly as round-5's own Nit-1 fix left round-4's
conclusion unchanged when it corrected the consumer count.

FIX 3(c) — tests/adr-612-bracket-phase-counting.test.cjs:2311,2340 still
said "four fence-blind sites" after round-5 (357ba671) added a fifth
(the retirement scan) in its own block below. Reworded both the section
comment and the `describe()` label to read as historical scoping of
round-4's own fix ("the four sites known at round 4 … a fifth was found at
round 5, see its own block below") rather than a live exhaustive claim.

Line count: 3 files, changeset 1/1, heading-selection test 17/8,
phase-counting test 6/2 (comment/prose-only; B0's own PIN test landed in
04b5a95f alongside T0/T05 since it was investigated as part of that same
Blocker's defect class, not in this commit — noted here for the record).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 970/970 (comment/prose-only diffs, no test count change).
`npx eslint` and `node scripts/changeset/lint.cjs` both clean.

* fix(#2761): W021's bracket remediation hint stops pointing at a command that hard-errors (round-7 Minor 2)

`checkBracketCoherence`'s W021 (added by 94abf5df) attached the fix hint
`Run \`gsd-tools roadmap upgrade --convention bracket\` to migrate
(dry-run by default)` to every bracket-convention W021 — both sub-checks
(`missing-bracket` and `mismatch`) share the single `addIssue` call at
src/verify.cts:2255-2256. But `roadmap-command-router.cts:204` throws
unconditionally for any `--convention` value other than
`milestone-prefixed`:

  $ gsd-tools roadmap upgrade --convention bracket
  Error: Only --convention milestone-prefixed is supported

This contradicts the PR's own two disclosures: the changeset ("`bracket`
is a READ-path opt-in until the migrator and write path land") and
docs/CONFIGURATION.md:188 ("There is no bracket migrator and no bracket
emit yet"). Reachability is the exact mid-migration repo this PR targets —
any bracket project with one un-migrated heading gets an unfollowable
instruction on every `validate health`.

Fix: one string. Replaced the hint with what a user can actually do today —
manually align the heading's bracket milestone to its section — and named
the tracked future landing (#612 PR-3) instead of a command that errors.
The milestone-prefixed sibling hint at src/verify.cts:2240 (a different,
already-functional convention/command pair — verified against
roadmap-command-router.cts:65) is untouched.

Line count: src/verify.cts is exactly 1 insertion / 1 deletion (one string
literal).

No test in the suite previously asserted this string's content
(`grep -rn "upgrade --convention bracket" tests/` was empty), so the
unfollowable hint shipped unpinned — `lint-fix-has-regression-test.cjs`
would not have caught a string-only change without a new test. Added one:
asserts the fix string both (a) does not match `--convention bracket`
(the specific pinned-before-this-fix hazard) and (b) equals the new string
exactly, covering the invariant a future edit must not re-break: no
unsupported `--convention` value named in remediation text users are
expected to run verbatim.

Verified end-to-end (not just unit-level) via /tmp/pr612rev/rv7f.cjs: the
W021 issue's `fix` field now reads the new string; `gsd-tools roadmap
upgrade --convention bracket` (and its --dry-run variant) still correctly
hard-error — that command remains unsupported, only the hint text changed.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 970 -> 971 (+1),
0 fail. `lint-phase-id-drift.cjs` clean; `npx eslint` on touched files:
0 errors (1 pre-existing unrelated no-elapsed-assertion warning, same file,
same line this arc's prior rounds already disclosed).

* chore(#2761): correct the bare-0 changeset disclosure + disclose W021's second sub-check (round-7 Minor 1 + Nit 1)

FIX 1 (Minor 1) — round-6's bare-0 changeset clause (1395bd89) was wrong in
three falsifiable ways:

  (a) Its own illustration (`### Phase 0:`) is exactly the LEGACY spelling
      04b5a95f made COUNTED. The residual exclusion after that fix applies
      only to the BRACKET-spelled token (`### [GSD.02] 0:`) — the clause
      named the wrong shape as its example.
  (b) "excluded from these counts" over-scoped the carve-out. The phase-0
      directory is admitted into `completed_phases`/`total_plans` in BOTH
      spellings (measured: B0 at HEAD has `completed_phases=2`,
      `accepts {"GSD.02-0-bootstrap":true}`). The exclusion that survives
      lives in `total_phases`/`phase_count` (heading counting) only.
  (c) The pre-existing "so `roadmap analyze` and `state json` report the
      same number" sentence (present since before this arc's bracket work)
      is now false for the bare-0 LEGACY-spelled shape: 04b5a95f's own
      commit message discloses this exact re-divergence as expected —
      `roadmap analyze` phase_count=2 vs `state json` total_phases=3 on T0
      — matching the disagreement legacy already carries today. The
      changeset still asserted unconditional agreement.

Rewrote both sentences: dropped the `### Phase 0:` example, scoped the
carve-out to `total_phases`/`phase_count`, named the bracket-spelled token
as the one that keeps analyze's sentinel reading, stated plainly that the
legacy-spelled form in a bracket repo IS counted (the mid-migration guard),
and qualified the "report the same number" claim to the `999` token, with
the bare-0 legacy-spelled shape named as the one exception and why.

FIX 3 (Nit 1) — `checkBracketCoherence` has always had two sub-checks
(its own docstring: "Two sub-checks, both surfaced as W021") but both the
changeset and docs/CONFIGURATION.md:188 described only the `mismatch`
sub-check. The `missing-bracket` sub-check — which fires on every
legacy-spelled heading in a bracket repo, the noisier of the two on a
mid-migration project — was undisclosed in both places. One clause added
to each.

Line count: 2 files, 1 line changed each (both are single-paragraph/
single-row files; git diff --stat reports 1/1 per file though several
distinct clauses were edited within that one line each).

Verified: `node scripts/changeset/lint.cjs` clean. Targeted suite
(adr-612-*, roadmap-parser, state, verify) unchanged at 971/971
(prose-only diffs, no test count change, no code touched).

* chore(#2761): resolvePhaseIdConvention's docstring no longer claims loadConfig drops the key

Upstream #2997 (aa7697fe, landed in `next` during this PR's final
verification) added `phase_id_convention: get('phase_id_convention') ?? null`
to `_baseConfig` in config-loader.cts — `loadConfig` now surfaces
`phase_id_convention` in its resolved config. This function's docstring
gave "loadConfig merges against CONFIG_DEFAULTS and drops keys it does not
know, and `phase_id_convention` is not among them" as the reason for
reading config.json directly instead of calling `loadConfig(cwd)`. That
rationale is now stale against live `next`.

Corrected the comment to state the two reasons that actually survive #2997:

  1. The workstream->root federation this function performs is a standalone
     resolution run against a GIVEN cwd, not necessarily the same base a
     `loadConfig(cwd)` call elsewhere in the codebase would federate from.
  2. Convention-ENUM validation is still #612 PR-4 work — this function
     returns the raw string unvalidated, exactly as the now-surfaced
     resolved key would.

Noted that #2997 surfacing the key makes consuming it from resolved config
(instead of re-reading config.json here) a natural PR-4 consolidation —
not this PR's scope. The "cycles were never the obstacle" close and every
other paragraph in the docstring (federation rationale, SCOPE note) are
untouched; they still hold.

Comment-only — no code behavior changed. This worktree's own history does
not contain aa7697fe (git merge-base --is-ancestor confirms neither branch
is an ancestor of the other; not rebasing per instruction), so this is a
textual correction against a documented external fact, not a functional
sync with upstream.

git diff --stat:

* fix(#2761): resolve phase_id_convention against the caller's workstream

`resolvePhaseIdConvention` took no workstream, so it resolved from
`planningDir(cwd)` — which falls back to `GSD_WORKSTREAM` only when its `ws`
argument is `undefined`. Every caller that passes a workstream by ARGUMENT
(they cannot set the env var per iteration) therefore read the convention from
the ROOT config while reading that workstream's ROADMAP.

Two reproduced consequences:

- A workstream that explicitly declares its own `phase_id_convention` had it
  ignored. Flipping ONLY the root config between bracket and milestone-prefixed
  changed which milestone that workstream extracted.
- `--workstream foo` and `GSD_WORKSTREAM=foo` disagreed on the same repo: the
  arg form fell through to the root config, the env form did not.

`resolvePhaseIdConvention(cwd, ws?)` now forwards `ws` to `planningDir`, and
both roadmap-parser call sites pass theirs — `extractCurrentMilestoneScoped`
(which already reads STATE from `planningDir(cwd, ws)`) and
`getMilestonePhaseFilter`'s lazy branch. `undefined` keeps the env fallback, so
convention-less call sites are byte-identical; `null` still means "explicitly no
workstream". The `undefined` vs `null` discriminator on `phaseIdConvention` is
untouched — only the base the `undefined` branch resolves FROM moves.

workstream-inventory's two sites (`countRoadmapPhases`, `inspectWorkstream`)
passed a literal `null` where they meant `undefined`, pinning every workstream
to the legacy grammar. On a bracket workstream whose milestone declares 3
phases that returned phaseCount 0 and fell back to the on-disk directory count;
it now returns 3. A non-bracket workstream is unchanged (legacy control pinned).

The workstream -> root federation is preserved: a workstream that declares no
convention still inherits the root, as config-loader does. That inheritance is
pinned so the fix cannot be over-applied into isolation.

* fix(#2761): classify missing phase details per occurrence, not per token

Under READING-B a phase's sentinel status lives in the BRACKET, so
`[GSD.999] 01` and `[GSD.02] 01` share a token and are not the same phase.
Both sides of the missing-detail check were keyed by the bare token anyway, and
both produced false negatives in `missing_phase_details`:

- The checklist scan built a token -> bracket-id Map, FIRST-WINS. Of two entries
  sharing a token, whichever the author wrote first classified both. With
  `- [ ] **[GSD.999] 01: Icebox**` above `- [ ] **[GSD.02] 01: ...**` the real
  phase inherited the icebox's sentinel verdict and vanished from the report;
  swapping the two bullets — same document, same phases — reported it. Pinned
  with a test asserting BOTH orders.

- The detail set was `new Set(phases.map(p => p.number))`, also token-keyed, so
  `[GSD.02] 01`'s heading marked token `01` present and satisfied
  `[GSD.03] 01`, which has no heading anywhere. Order-independent, same class.

Both sides now key on an occurrence key: the owner's `bracketQualifiedKey`
(fold- and padding-insensitive, so `[gsd.2] 01` and `[GSD.02] 01` are one
phase), falling back to a fold-normalized composite for the two shapes that
grammar refuses — a token carrying its own hyphen, which splices to an id whose
trailing segment the qualified-key grammar truncates (the hazard
`getMilestonePhaseFilter` guards with its own `!token.includes('-')`), and any
id it does not accept. With no bracket id the key IS the bare token, so the
legacy path keeps its exact keys and dedupe order.

The emitted value is unchanged — `missing_phase_details` stays an array of bare
tokens, matching `phases[].number`. Only the classification moved to the
qualified key, so two brackets' `01` both missing report `01` once instead of
one silently covering for the other.

* test(#2761): replace the two wall-clock ReDoS assertions with algorithmic bounds

Both guards asserted elapsed wall-clock time — `Date.now()` against a 20s
ceiling in the coherence suite, `process.hrtime.bigint()` against 1s in the
read-tolerance suite. Those measure the host machine rather than the SUT and
flake on a loaded CI runner (RULESET.TESTS.no-timing-assertion). Per
RULESET.TESTS.delete-bad-tests they are REPLACED, not skipped, and the
behavioral property each one guarded is preserved.

The property is "the widened bracket patterns do not backtrack
catastrophically", which is a claim about growth, so it is now stated by
scaling the input instead of by timing it:

- validate health runs the pathological unclosed bracket at 4,000 and 16,000
  characters and must return the same correct result (no W021) at both.
- The four reader entry points run five ReDoS shapes at 5,000 and 20,000 and
  must name exactly the phases each shape should name at each size, with the
  variant cardinality unchanged across the two.

Catastrophic backtracking is superlinear, so a regression cannot complete the
4x leg under any ceiling, while a bounded matcher is indifferent to the
scaling. The one attack that is well-formed-but-oversized now pins its reading
precisely (`['1'.repeat(n)]`) rather than being lumped in with the malformed
ones. A positive control asserts the readers still extract a well-formed
bracket heading, so "names no phase" cannot pass by the readers being inert.

`{ timeout }` is a hang backstop, not an assertion: it turns a runaway into a
deterministic failure instead of a suite that never returns.

* fix(#2761): give the bracket grammar one owner and teach the drift guard to see it

The bracket milestone-intro grammar was re-typed verbatim in three readers —
roadmap-parser's bracket-fallback selector, state's `isMilestoneBounded` and
verify's `checkBracketCoherence` — which is exactly what #2761's own gate
forbids ("no token literal outside src/phase-id.cts"). `check:phase-id-drift`
reported clean the whole time: its detector only ever knew the phase-NUMBER
token grammar, so the bracket class `[A-Z][A-Z0-9_]*` was invisible to it.

Ownership. `src/phase-id.cts` now exports the class as
`BRACKET_PROJECT_CODE_SRC` and the intro in the two shapes its readers need:
`bracketMilestoneIntroSrcFor(milestone)` (pinned to one milestone) and
`BRACKET_MILESTONE_INTRO_CAPTURING_SRC` (milestone captured). The pinned
builder owns the pad2 spelling rule too — "canonical spelling only, not `0*N`"
was previously restated in prose beside each copy, a convention two files had
to keep agreeing on by hand. `BRACKET_ID_SRC`, `BRACKET_ID_PREFIX_RE` and
`BRACKET_QUALIFIED_KEY_RE` now compose the class rather than re-spelling it.
All three call sites consume the owner; the regex sources are byte-identical to
what they spelled, asserted against hand transcriptions of the pre-fix lines.

Guard. `scripts/lint-phase-id-drift.cjs` gains a bracket rule
(`findBracketGrammarDrift`), wired into `scanRepo` and tagged `kind`. It
deliberately does NOT copy the token rule's `line.includes(CANON_REF)` escape:
that escape is line-level, and verify's copy referenced the owner for the
MILESTONE field on the same line as the re-typed PROJECT-CODE class — so a
bracket rule with that escape would have kept passing on the very site under
review. Partial ownership is the drift; only a dedicated `// phase-id-owner:`
comment suppresses it.

Proof, end to end: planting the shipped verify.cts literal back into src/ makes
`npm run check:phase-id-drift` exit 1 naming `[bracket] src/verify.cts:1475`;
restoring it returns the gate to ok.

Tests. phase-id-drift-guard carries all three shipped literals as negative
fixtures, the same-line-owner-reference case, the case-widened evasion variant,
the sanction rules, and a temp-tree scan proving the rule is wired into
scanRepo rather than merely exported. continuation-grammar-parity drives the
pinned and capturing shapes over a 12-entry corpus and requires the same
verdict from both plus the same captured milestone — widening either alone
fails there.

* test(#2761): drop the out-of-scope source-grep exemption from the selector pin

The baseline-selector pin in tests/adr-612-bracket-heading-selection.test.cjs
read `src/*.cts` with readFileSync and regex, claiming the no-source-grep
escape with a source-text-is-the-product reason. CONTEXT.md's documented scope
(RULESET.TESTS.no-source-grep.exemption) reserves that escape for tests whose
subject is a runtime CONTRACT FILE — STATE.md, config.toml, hooks.json, agent
.md — and `src/*.cts` is none of those.

It was also broader than it looked: eslint-rules/no-source-grep.cjs matches the
marker in ANY comment in the file, so one block's claim disarmed the rule for
the whole ~700-line suite.

The pin itself is worth keeping — the BASELINE ARGUMENT at each call site is a
fact no behavioural test can recover (flipping verify's milestone-complete site
from LABEL_ONLY to ANY_BRACKET grants a tolerance it has never had, and every
behavioural test still passes), so pinning it does require reading the authored
source. That reading moved to `scripts/lint-phase-id-drift.cjs` — the seam's
own guard, where source scanning is sanctioned (`warn` scope) and already
happens for the grammar rules — as `countSelectorBaselines` /
`scanSelectorBaselines`, which return a structured census. The test asserts on
the returned data and touches no file text.

CONTEXT.md is unchanged: the exemption scope was not widened to fit the test.
No marker remains in the suite, so the rule is live across all of it again, and
eslint passes with the escape removed rather than relocated. A floor assertion
pins that the census actually found the five consumers, so the "no other file
consumes the selector unpinned" check cannot pass on an empty scan.

* docs(#2761): rewrite the changeset as a lead + deltas instead of one paragraph

The fragment was a single ~6,400-character paragraph that opened on internal
mechanics, buried the user-visible change, and named an internal test path
(tests/adr-612-bracket-phase-counting.test.cjs) that means nothing to a reader
of the CHANGELOG.

It now leads with what a user sees — bracket-style phase IDs are recognized on
the read path across roadmap, validate, verify and state — followed by compact
bullets for the behavioral deltas, the opt-in caveat, and the upstream
consequences. Both merge-added disclosures are kept: the #3185 legacy-sentinel
Phase-0 delta with the reason the bracket counter keeps the narrower rule, and
the enumerator's convention-argument default flip with the four newly-scoped
read surfaces and the note that archival and milestone-completion paths are
unchanged. Two deltas from this review round are stated as their own bullets:
per-occurrence classification in `missing_phase_details`, and workstream-scoped
convention resolution including the workstream-rollup count change.

The internal test path is gone and the body is down to ~3,850 characters. The
bullets render as sub-bullets under the CHANGELOG entry and the `(#NNNN)`
suffix still lands on a trailing paragraph rather than mid-list.
`npm run lint:changeset` passes.

* test(#2761): use helpers.cleanup in the drift-guard temp-tree test

`local/no-raw-rmsync-in-tests` rejects a bare `fs.rmSync` in tests — the shared
helper carries the Windows-EBUSY retry budget. The temp-tree scan added with
M3's guard coverage test used the raw call.

* docs(#2761): correct the occurrenceKey comment on qualified-key normalization

The comment claimed `bracketQualifiedKey` is "fold- and padding-insensitive, so
`[gsd.2] 01` and `[GSD.02] 01` are one phase". The fold half is right; the
padding half is not. `BRACKET_MILESTONE_NUMERIC_SRC` is `(?:[1-9]\d{2,}|\d{2})`,
so `bracketQualifiedKey('GSD.2-01', 'bracket')` returns null and that input
takes the composite fallback instead.

No behavior change — the two key spaces use different separators and cannot
collide — but the claim was checkable and wrong. Restated: the owner case-folds,
and padding-tolerance is not a property it has or needs, because each accepted
milestone has exactly one canonical spelling and `[GSD.2]` is malformed rather
than an alternate spelling of `[GSD.02]`.

* ci(#2761): give the coverage-gate job the heap floor the shard jobs already have

The gate's report steps parse ~2.5GB of merged raw V8 dumps in one
process at the runner's implicit ~4GB ceiling, so pass/fail comes down
to GC timing (run 31338081337 OOM'd; next passes the same volume at
28s). Deterministic locally: crashes at --max-old-space-size=4096,
completes in 11s at 8192. PR shard data is within 0.15% of green next
runs — the load is pre-existing, only the ceiling was missing. #2952
set 6144 on the shard-collection step; the gate job was missed.

* Revert "ci(#2761): give the coverage-gate job the heap floor the shard jobs already have"

This reverts commit 03c74a97c911e9ddc53675aded9c9bbb89f14cd1.

* fix(#2761): thread the resolved convention into cmdStateValidate's phase-directory lookup

#3208 replaced cmdStateValidate's `startsWith` prefix test with the canonical
`phaseKeyFromDir(...) === selectedPhaseKey` comparison. That is the right
surface, and it is why the lookup now needs the resolved `phase_id_convention`,
which the rewrite does not pass.

`phaseKeyFromDir` deliberately refuses to read a bracket directory without an
explicit signal (ADR-2121: a bracket dir is string-indistinguishable from the
legacy letter-prefixed-decimal family), so un-threaded it returns the whole dir
name as the key — `GSD.02-05-real-work` -> `GSD.02-5-REAL-WORK` — while the
STATE side is the bare `05` that `parsePhaseFromProse` yields. Both sides of one
comparison derived under different conventions is #2562's defect class, and this
file's other three `phaseKeyFromDir` call sites already thread against it.

Observable: a bracket repo whose phase directory plainly exists reported
`valid: false` and "no phase directory matches phase 05", and the drift scan
(plan-count mismatch, verification status) never ran. The pre-#3208 `startsWith`
missed the same directory but skipped silently, so this is a visible-failure
regression on bracket repos, not a new miss.

Non-bracket conventions are byte-identical by construction: `extractPhaseToken`
branches only on `=== 'bracket'`, so null / 'milestone-prefixed' / unresolvable
compile the same path as the un-threaded call. The flat-legacy twin assertion
pins that.

* docs(#2761): note the cmdStateValidate convention threading in the changeset fragment

The fragment described the bracket read path as of the pre-merge branch. 504c64ff
added a shipped behaviour change — `state validate` now resolves bracket phase
directories — that the fragment did not mention, so the rendered changelog would
have under-described what ships.

Body text only; `type` and `pr` are untouched.

* test(#2761): invert the inherited-wart characterization — #3225 fixed it upstream

Required by the merge of next @ 86101ee6; test-only, no src delta.

This branch disclosed rather than fixed a pre-existing upstream wart: on a
LEGACY repo, `### Phase 999:` warned from `validate consistency` while
`validate health` suppressed it — the two verbs contradicting each other.
The case was pinned as a characterization test ("INHERITED WART, unchanged")
precisely so it would INVERT if upstream ever closed it, rather than rot
silently.

ae7dc529 (#3225) closed it, by adding the `isSentinelPhaseId` guard to this
very loop. So the assertion inverted on the merge — as designed. Flipped to
assert the FIXED behaviour rather than deleted: it is the negative-space
proof that this branch's `sentinelPhases` guard never had to grow a legacy
reading of its own, and it reds if a future conflict resolution keeps our
guard while dropping upstream's.

Added a scope control alongside it (a legacy NON-sentinel `### Phase 09:`
with no directory still warns), so deleting the loop outright cannot pass.

Union proven load-bearing in BOTH directions against the merged tree —
neither guard subsumes the other:
  - drop `isSentinelPhaseId(p)` (ours only) -> 1 red, exactly this case.
    Note upstream's own #3225 tests stay GREEN there: they cover the
    disk-side loops (sentinel dir on disk) and the gap-numbering filter,
    not the ROADMAP-side loop. This case is that site's only coverage,
    which is the second reason to keep it rather than delete it.
  - drop `sentinelPhases.has(p)` (upstream only) -> 4 red bracket suites
    (icebox-not-missing, health/consistency agreement, occurrence-aware
    suppression, checklist-index suppression).

tests/adr-612-bracket-read-tolerance.test.cjs 79 -> 80, all green.

* test(#2761): pin the three re-homed W006/W007 reads the merge left unfalsifiable

#3309/#3310 deleted the helpers this PR threaded (collectDiskPhases,
collectDiskPhaseEntries, collectArchivedPhaseDirNames,
forEachArchivedPhaseToken) and rebuilt their reads inside
src/planning-snapshot.cts + src/health-diagnostic-rules/*.cts. The convention
threading moved with them in the merge commit — but a mutation sweep over the
re-homed sites found three where reverting the convention argument changed real
CLI output and NOT ONE existing test went red. The pre-migration sites were
covered indirectly, through helpers that no longer exist, so the coverage did
not survive the relocation even though the behaviour did.

Each case is pinned at the CLI with its flat-legacy twin as the byte-identity
control, plus a non-vacuity control in the opposite direction:

  archivedPhaseTokens      revert -> "Phase 05 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for a phase whose only directory is
                                     under .planning/milestones/v1.0-phases/
  roadmapPhaseCheckboxes   revert -> "Phase 09 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for an unstarted `- [ ]` phase
  W007's extractPhaseToken revert -> "Phase GSD.02-77-orphan exists on disk"
  (roadmap-disk-consistency)         instead of "Phase 77 exists on disk"

Red/green: each single-line revert reds exactly its own case and nothing else;
every legacy control stays green in all three runs.

NOT pinned, and disclosed as droppable rather than given an unfalsifiable test:
buildValidPhaseSet's extractPhaseToken(dir, convention) in W002. That rule
unions disk tokens with roadmapDeclaredPhases and archivedPhaseTokens, and any
STATE.md reference a bracket disk token would rescue is already rescued by the
ROADMAP half — probed directly, the argument makes no observable difference. It
is threaded because it restores collectDiskPhases(planBase, convention)'s
derivation exactly, not because a test needs it.

Test-only; revertable independently of the merge commit.

* test(#2761): pin the two reads the #3165 extraction left unfalsifiable

DROPPABLE, offered as such. Test-only; the merge commit is correct without it.

#3428's extraction gave `collectAnalyzePhases` TWO call sites — the scoped
milestone window and the truncated-window recovery path. The merge threads
`convention` into both and swaps `detailKeys` with `phases` across the recovery.
Neither of those was falsifiable by the suite as it stood:

  - passing a NULL convention at the FALLBACK site, with the scoped site still
    threaded, is green across all 518 tests of the bracket, roadmap and
    milestone-window files. Every pre-existing bracket assertion reaches the
    enrichment through the scoped window, so none of them can observe the
    fallback's reading at all;
  - dropping `detailKeys = fallbackScan.detailKeys;` — the line this merge
    authored — is likewise green, because no fixture that reaches the recovery
    path carries a checklist bullet, so `missing_phase_details` is `null`
    either way.

That is the same hole class lap 3 closed in 9914359c: an argument whose revert
changes real CLI output with zero reds.

Pinned at the CLI on the shape that reaches the fallback on a bracket repo — a
MID-MIGRATION ROADMAP: bracketed ACTIVE milestone, its phase-detail sections
and checklist bullets sitting after an intervening CLOSED legacy milestone (so
the window closes over prose only), plus one legacy `### Phase N:` section of
its own. Six tests:

  - a NON-VACUITY control that removes the phase directories, so #3428's own
    precondition fails and the result is the empty one the recovery exists to
    replace — this is what proves the rest read the FALLBACK's output rather
    than the scoped scan's;
  - the directory assertion (`disk_status`/`plan_count`/`summary_count` for
    canonical `{CODE}.{MM}-{PP}-slug` dirs) + a flat-legacy twin asserting
    byte-equal shape, and that the twin is the right answer rather than a
    shared wrong one;
  - `missing_phase_details: null` for phases the recovery just found, and its
    companion direction — a bullet with no heading anywhere is STILL reported,
    so a fix that merely suppressed the report does not pass;
  - a non-bracket repo taking the same path unaffected.

Red/green, each mutation reverted afterwards:
  - fallback call site -> `null` convention: exactly 2 reds, both directory
    assertions in this block; 307 other tests green, including upstream's own
    #3428 tests in tests/milestone-window-single-owner.test.cjs.
  - `detailKeys` swap deleted: exactly 2 reds, both `missing_phase_details`
    assertions; 414 other tests green.
  - `matchPhaseDirs` 3rd argument dropped (the lap-2 site): 4 reds — the 2
    already on record plus this block's 2, which is the point: one seam, now
    reached by two paths.

DISCLOSED IN THE TEST BODY WITH MEASURED OUTPUT, not fixed: `hasPhaseEntries`
(src/roadmap-parser.cts) is convention-blind, so on a PURE-bracket ROADMAP the
window classifies COMPLETE and #3428's recovery is gated off entirely. That
document returns `{"scope":"complete","phase_count":0,"next_phase":null,
"phases":[]}` — the "genuinely empty milestone" answer, the indistinguishability
#3184 introduced `scope` to remove — where the flat-legacy twin returns
`{"scope":"truncated","phase_count":2,...}`. Widening it changes the value of an
upstream-owned output field on bracket repos, so it is a behaviour slice (the
PR-2.5/PR-4 convention-less-readers question), not a merge-round change. The
mid-migration shape pinned here is the reachable half.

* fix(#2761): mirror the bracket terminator in the milestone-scope write guard

parser's terminator vocabulary — "a level 1-3 heading that is not a Phase
heading and carries a milestone signal". On this branch that vocabulary is
convention-SELECTED: `computeBracketSectionEnd` adds `isBracketMilestoneBoundary`
as a terminator arm, and the ADR-canonical `## [GSD.09] Hidden` carries NO
vN.N token, NO ✅/📋/🚧/🔄 marker, and not the word "Milestone". Left
unmirrored, the guard accepted exactly the description it exists to reject.

NOT a defect on clean next — a bracket heading terminates nothing there. The
branch widens the terminator set, so the branch owns the mirror.

MEASURED at the CLI seam before the fix (bracket fixture, one milestone,
one phase):

  $ gsd-tools phase add $'Sneaky\n## [GSD.09] Hidden'   -> exit 0, written
  $ gsd-tools phase add 'Innocent follow up'            -> exit 0, written
  $ gsd-tools roadmap milestone-scope
    { "scope": "complete", "phases": ["01","1"], "phase_count": 2 }
  $ grep '^### Phase' .planning/ROADMAP.md
    ### Phase 1: Sneaky
    ### Phase 2: Innocent follow up      <- in the document, out of the window

After the fix the first add exits 1, ROADMAP.md is byte-unchanged and no
phase directory is created. The legacy twin (same text, no
`phase_id_convention`) still exits 0 — opt-in only, base behaviour preserved.

SHAPE
- `findMilestoneScopeHeadingLines(text, convention)` — REQUIRED, the same
  tripwire `scanMilestonePhaseIds` carries in the merge commit and for the
  sharper reason: a blind call here fails OPEN (the guard quietly ACCEPTS a
  window-narrowing description), so a future call site must fail to COMPILE.
  Census is one caller, which pays nothing for it. A non-bracket value takes
  the pre-existing path byte-identically. The bracket arm routes through
  `isBracketMilestoneBoundary`, the same single-owner phase-vs-milestone
  discriminator `computeBracketSectionEnd` consults; no second bracket-heading
  grammar is spelled here.
- `selectedBracketId` is deliberately `null`, so the same-milestone
  CONTINUATION exemption never fires and a value naming the ACTIVE milestone
  is flagged too. That is this predicate's third stated conservatism and
  rests on its own existing argument: which milestone is active is a property
  of the document at write time, not of the text being validated, and
  over-rejecting is one-directional.
- `assertDescriptionPreservesMilestoneScope` takes `cwd` and resolves through
  the branch's tolerant try/catch — this guard runs BEFORE `loadConfig` and
  before the ROADMAP existence check, so an unresolvable convention must
  degrade to the legacy vocabulary, never turn a rejection into a crash.
- The error's marker list gains the bracket form only when the project is on
  the bracket convention.

RED/GREEN
- Revert the bracket arm -> 2 reds (phase add; insert + add-batch), the
  non-bracket control and both no-false-positive cases stay green.
- Revert the probe threading in the merge commit -> 1 red (the probe case).
- 6 new cases in the #3262 file, each with a non-bracket or
  no-false-positive control: fenced bracket milestone heading and bracket
  PHASE heading are both non-violations.

Droppable: revert this commit and the merge stands on its own; the branch
then ships the gap as a disclosure instead of a fix.

* docs(changeset): narrow the enumerator claim to the directory set — per-entry rendering in progress/stats/init-manager is display-slice scope

Round-7 review confirmed 3 of the 4 surfaces named by the closing claim
parse each directory or heading with legacy-only patterns that live in
files this PR does not touch (commands.cts:1766, commands.cts:2116,
init.cts:2241). The claim now states exactly what this slice delivers:
the scoped directory set. Their per-entry conversion is display work,
deferred to the epic's display PR with the statusline/progress-card
gates it belongs beside.

* fix(#2761): de-accident the unmatched-milestone bracket fixture, re-pin to #3480's withhold contract

tests/adr-612-bracket-phase-counting.test.cjs:515 ("a milestone that
does NOT match STATE is not scoped in") asserted total_phases === 0.
Since today's merge brought in 70b5c1a1 (#3354/#3480, already in
`next`), buildStateFrontmatter withholds total_phases (omits the key,
read back as null) for a milestone that is genuinely sectioned but
matches no ROADMAP heading, instead of substituting a computed number
— the fixture's `state json` read now returns null, failing the
strictEqual(0) assertion.

The original single-section fixture's 0 only ever survived by
accident: hasMilestoneSectioning requires >=2 milestone-vocabulary
headings to call a ROADMAP sectioned, and its isPhaseHeading helper
recognizes only the legacy `Phase N:` text form — so the bracket
phase heading `### [GSD.03] 09: Not this milestone` (title containing
the word "milestone") miscounted as a second milestone heading,
tipping hasMilestoneSectioning true and routing to the disk-count
branch. With that miscount removed, the same one-section fixture
reads 1 (the non-matching milestone's phase count leaking into v2.0's
total) — proving the pinned 0 was never validating the scoping this
test claims to exercise.

Replaced the fixture with two genuine milestone sections (GSD.03,
GSD.04), neither matching STATE's v2.0, with phase titles carrying no
incidental vocabulary — the real #3354 shape. Re-pinned the assertion
to null, matching upstream's own tested contract (tests/state-
document.test.cjs, "#3354 with nothing stored, the key is omitted
rather than written from the dir count").

Verified: file green 3/3 runs (104/104), full state-suite regression
771/771 green. The isPhaseHeading gap that made the old fixture
accidental is a real, pre-existing, upstream-owned limitation
(hasMilestoneSectioning only guards >=2-section conflation, not a
single non-matching section leaking through) — not introduced by

* chore(#2761): exempt two self-authored-fixture regexes from #3441's unbounded-quantifier rule

Both sites parse the STATE.md the test itself just wrote to its own
tmpdir — fixed-size fixture output, not adversarial or document-scale
input. Exempted with the justification-comment pattern the tree's own
tests use for this exact case (settings-integrations, copilot-install,
research-agent-profiles). The sites predate the rule; #3441 landed on
next this morning and this branch picked it up in the catch-up merge.

* fix(#2761): fix forward two next-movement test regressions from the round-11 rebase

origin/next's #3573 newly threads STATE's stored `milestone:` value into
`state json`'s buildStateFrontmatter call (previously always `undefined` on
that read surface). Two pre-existing PR-2 fixtures reach code paths that
call never exercised before that merge:

- RED (repro2 case C): a version-less, all-bracket-id ROADMAP now hits
  getMilestonePhaseFilter's pre-existing (unaffected by this branch) row-5
  `versionResolved && !headingFound => SCOPE.UNSCOPED` rule, which withholds
  `progress.percent` even though the scoped total_phases/completed_phases
  are still correct. That row-5 rule is load-bearing for six other
  version-less-document pins in this same file; narrowing it broke seven of
  them in testing, so production code is untouched here. Reassert the
  test's real claim (scoping, via total_phases/completed_phases) and
  disclose the now-withheld percent instead of silently dropping it.

- PIN (repro12 LEGACY control): a fenced-example-vs-real version heading
  fixture. #3573 routes this read through sliceMilestoneWindow (fence-aware)
  instead of the legacy anyMilestonePattern raw scan (fence-blind) this pin
  was disclosing as out of scope, so the fixture no longer exercises the
  blind path — total_phases moves from the whole-doc 4 to the correctly
  scoped 2. Re-pinned with an upstream-attributed comment, matching this
  file's existing house style for prior origin/next movements (see the
  sibling "PIN (G3 LEGACY control)" comment).

Both are test-only fix-forwards: no production code changed. The remaining
12 failures in this file at 27363e9d0 (dropped seam commits' VERIFICATION.md
naming + fixture updates) are pre-existing and deferred to the stacked
follow-up per the task's own scope.

* fix(#2761): thread phaseIdConvention explicitly at the two write-adjacent enumerator call sites (round-11 BLOCKER)

listMilestonePhaseDirs' phaseIdConvention param lost its `= null` default
(phase-locator.cts), so an omitted convention now means "resolve from
config" instead of "explicitly not bracket" — a deliberate flip, but
milestone.cts and state.cts were not in the PR-2 diff and both call the
enumerator without threading it:

- milestone.cts cmdMilestoneComplete (the single #3597 shared derivation
  feeding the stats loop, --dry-run preview, and the real archive/rename
  pass) now resolves phase_id_convention once and threads it explicitly,
  so a bracket project's `milestone complete` archives its real
  bracket-declared phase directories instead of silently inheriting
  whatever the enumerator's lazy default resolves to.
- state.cts cmdStateUpdateProgress's own enumerator call threads the same
  resolved convention. Empirically this does not change the #3217 withhold
  gate (scope is assigned before headingConvention resolves in
  getMilestonePhaseFilter, so it's convention-independent either way) or
  the reported percent (already correctly threaded via
  computeUpdateProgressPreview -> buildStateFrontmatter); it closes a
  second, silently-resolved answer to the same question this file's own
  ONCE-and-THREAD rule (~:2300) already states as policy.
- state.cts's other listMilestonePhaseDirs call site (the state-sync
  scope-only read, ~:4791) is left unthreaded on purpose, with an inline
  note explaining why: only `.scope` is consumed, and `.scope` is set
  before convention resolution in getMilestonePhaseFilter, so it cannot
  disagree with a threaded convention.

Both enumerated sets are pinned by new tests (round-11 BLOCKER block in
tests/adr-612-bracket-phase-counting.test.cjs), including a mutation-style
regression check on the milestone.cts fix (forcing the un-threaded default
back on makes the pinned test fail, catching a regression to the
pass-all-degrade legacy reading).

* fix(#2761): correct the changeset's false archival claim and amend ADR-612 for the round-11 M2(2) split scope

The changeset (.changeset/2761-bracket-read-tolerance.md) asserted "The
archival and milestone-completion paths are unchanged" — false: both
paths reach the widened enumerator, and this PR now threads their
convention explicitly (previous commit). Replaced the closing paragraph
with an accurate description of what changes for a bracket project at
those two call sites, and notes both enumerated sets are pinned by tests.

ADR-612 (docs/adr/612-bracket-phase-id-convention.md) amended per M2(2):
the 2026-08-03 PR-2/PR-4 boundary proposal is added in-body (PROPOSED,
not stamped — mechanics per docs/contributor-standards.md:143 reserve ADR
ratification to maintainers), rescoped to what actually ships in PR-2
(#2761) now that the round-11 M1 split moved the completion-seam
threading (isPhaseArtifact/scopeToPhase, phase-id.cts:964-1090) out into
a separate, stacked follow-up PR referenced generically via epic #612:

- state.cts read-tolerance (both total_phases derivations, the #1514
  retirement filter) moves into PR-2's row, alongside milestone.cts,
  reflecting the round-11 fix above.
- the write-observability point is restated in terms of what actually
  ships: explicit threading at two named call sites, pinned by tests,
  rather than silent inheritance.
- the completion-seam threading is named and explicitly excluded from
  PR-2's scope, with a new ratify item (5) and a Negative consequence
  bullet covering the sequencing cost.

* fix(#2761): repair round-11 response gaps — disk-side sentinel bug, test-fixture bug, scanMilestonePhaseIds caller drift

Four independently-verified gaps in the round-11 repair response:

1. isSentinelPhaseId (src/phase-id.cts) treated a bare, untagged phase
   directory under phase_id_convention: "bracket" (`0-bootstrap`, no
   `{CODE}.{MM}-` prefix) as sentinel milestone 0 by falling through to the
   legacy leading-int rule when the bracket-tag match failed. This silently
   dropped a real, on-disk, milestone-declared phase directory from
   `listMilestonePhaseDirs` (phase-locator.cts:424, the only unguarded call
   site) and undercounted completed_phases/percent. Mirrors the carve-out
   already present on both heading-side counters (state.cts's
   countRoadmapPhaseHeadings guards its bare-0 exclusion with `bracketId &&`;
   roadmap-parser.cts's scanMilestonePhaseIds composes the bare-token rule as
   999-only) — under bracket convention, milestone 0 is expressed only via an
   explicit bracket tag, so an untagged leading 0 is a real phase token.

2. tests/adr-612-bracket-phase-counting.test.cjs's writeProject fixture
   hardcoded `01-VERIFICATION.md` for every "complete" phase dir regardless
   of the dir's real phase token. Under legacy convention this file already
   correctly failed #3511's strict isPhaseArtifact match for any dir other
   than phase 01 (the fixture never modeled what it claimed to); under
   bracket convention the pre-existing ambiguity fail-safe admitted it
   regardless. The two readings' disagreement was mistaken for a missing
   completion-seam threading (isPhaseArtifact/scopeToPhase convention
   awareness, correctly split out to the stacked #3644 per round-11's M1).
   Replaced the hardcoded name with verificationNameFor(dir), deriving the
   real per-phase filename from the production normalizePhaseName the same
   way cmdScaffold does — the 7 failing "flat-legacy-twin" / CHARACTERIZATION
   assertions pass on #2867's own code with no seam threading required, and
   the genuine seam-dependent cross-phase-stray-exclusion test the fixture
   fix would otherwise have hidden lives on the stacked branch instead.

3. tests/roadmap-parser.test.cjs's two #3577 tests still called
   scanMilestonePhaseIds with the old single-Set return shape; this PR
   changed it to `{ ids, qualifiedIds }` for every other caller but missed
   these two, which don't touch #2761/bracket code at all. TypeErrors at
   runtime, not silently-wrong assertions. Updated both call sites.

4. .changeset/2761-bracket-read-tolerance.md gains a paragraph disclosing
   fix 1 above, so the changeset stays accurate to what actually ships (the
   round-11 BLOCKER was exactly this changeset going stale once).

Verified: tests/adr-612-bracket-phase-counting.test.cjs +
tests/continuation-grammar-parity.test.cjs + tests/roadmap-parser.test.cjs =
354/354. adr-612-{coherence,grammar,heading-selection,read-tolerance,
selection.property}.test.cjs + collision-characterization = 287/287
(CONFIRMED-CLEAN set, unaffected). Full unfiltered suite run separately.

PR #3643 (round-11's M1 split, opened draft per that round's explicit
requirement) was auto-closed by this repo's own draft-PR policy 11 seconds
after opening — draft PRs are unconditionally closed here. Reopened as
non-draft #3644 (same branch, same commits, DO NOT MERGE / stacked-on-#2867
marker in the body, enhancement template) since the repo's own bot confirms
non-draft contributor PRs are tolerated even off-template.

* fix(#2761): narrow the state-update-progress pin claim to what mutation testing actually proved, add the test that covers the rest

Round-11 BLOCKER response gap (verified, not a guess): the changeset and
ADR-612 amendment point 2 both claimed the round-11 tests pin
`cmdStateUpdateProgress` so "a future change to the enumerator's default
cannot silently move ... what state update-progress reports without failing
a test." Mutation testing disproves this. Reverting BOTH the state.cts
explicit `phaseIdConvention` thread AND simulating the phase-locator.cts
pre-#612 hardcoded-null default (`phaseIdConvention: null` at that one call
site) leaves the existing PIN test ("writes a real percent for a
bracket-scoped milestone") green, because that percent comes from
`computeUpdateProgressPreview` -> `buildStateFrontmatter`, a separately and
already-correctly-threaded derivation the state.cts inline comment at ~:965
already candidly documents.

What the reverted thread DOES change, empirically, is `phaseDirs`/`totalPlans`
— the enumerated `.value` this call site feeds into the #3233 zero-plans
no-op gate a few lines below. That is the one place a regression at this call
site is observable in the command's output. Added a test that pins exactly
that: a bracket milestone whose declared phases carry no plans on disk,
alongside a decoy directory that plainly does not belong to the milestone
(no bracket tag, no phase token) but does have a plan. Correctly scoped, the
decoy is excluded and the #3233 no-op fires (`updated: false`). Degraded to
the pass-all legacy reading, the decoy is swept in, `totalPlans` flips
nonzero, and the no-op never fires (`updated: true`).

Mutation-tested against both scenarios:
- Reverting ONLY the state.cts explicit thread (falls back to `undefined`,
  which `getMilestonePhaseFilter` resolves via the identical
  `resolvePhaseIdConvention(cwd, undefined)` call the explicit thread also
  makes): new test stays green — confirms the single-hunk thread really is
  pure single-derivation hygiene, exactly as the existing inline comment
  claims, for this test too.
- Forcing `phaseIdConvention: null` at that call site (the combined-revert
  scenario the round-11 mutation testing actually exercised): new test FAILS
  (`updated: true, percent: 0` instead of the expected `updated: false`).
  Restoring the real code makes it pass again.

Narrowed the changeset and ADR-612 point 2 prose to match: `cmdMilestoneComplete`'s
enumerated set is pinned against a pass-all-degrade regression (genuine,
already verified in round 11); `cmdStateUpdateProgress`'s own call site is now
pinned against the #3233 zero-plans no-op specifically, not against the
reported percent, which the prose no longer claims. Added a one-line pointer
to the new test in the state.cts inline comment. No production behavior
changes — test and documentation only.

* docs(#2761): reconcile ADR PR-2 module map

The rebase replayed this file's pre-#3639 patch over next, reverting the
isSentinelPhaseId(token) -> isSentinelPhaseDir(dirName) fix: the extracted
token is milestone-stripped, so a bracket sentinel (GSD.999-07-icebox,
GSD.00-01-backlog) was invisible to the id predicate and false-fired W007.
Restores upstream's call and comment verbatim; the branch's convention-aware
token remains for the diagnostic message only.

Caught by next's own #3639 regression tests (CI shard 2). Local: the file's
18/18, health-diagnostic-rules 165/165, full npm test exit 0.

* docs(#2761): ratify scope and correct surface claims

* test(#2761): strengthen legacy selection and drift claims

* docs(#2761): correct the enumerator claim, scope list, and ratification receipt

Three documentation corrections, none touching production code.

The changeset claimed the shared phase-directory enumerator "now defaults its
convention argument to 'not yet resolved' rather than 'resolved, and not
bracket'". That is false: `phase-locator.cts:375` still destructures
`phaseIdConvention = null`, and the lazy resolve-from-config fires only on
`undefined` (`roadmap-parser.cts:941`, `:1928` — whose own comment records that
"explicit null still means 'resolved and non-bracket'"). Measured: only 4 of 17
`listMilestonePhaseDirs` call sites thread a resolved convention (`milestone
complete` and `state`'s three). The changeset went on to name `progress`,
`stats`, `phase list` and the init manager view as now receiving a correctly
scoped set — those are precisely callers that omit it. Replaced with what the
code does, and the deferral stated plainly.

The ADR's PR-2 row omitted `scripts/lint-phase-id-drift.cjs` (+141/-14) and
`scripts/lint-phase-enumeration-drift.cjs`, both changed by this PR. An
under-claim rather than an over-claim, but the row is the epic's
scope-of-record.

Ratify item 5 asserted maintainer ratification while citing only the review that
raised the question. It now cites the review that granted it (#2867 review
`5012940978`, 2026-08-24) and quotes its terms, so the claim carries its receipt.

Found by an adversarial review pass over the round-12 diff. (#2761)

* fix(#2761): drop the no-op --json that strict argv now rejects

Surfaced by the rebase onto next, not by a change in this PR's subject.

#3884 ("failure is a value — strict argv", e20744eac) made an unrecognized
flag a hard error: `state validate --json` now exits 1 with
`unknown flag "--json"; accepted: --strict` on stderr and EMPTY stdout,
where the token was previously accepted and ignored. `state validate` never
had a `--json` flag — JSON is its only output shape — so the argument was a
silent no-op from the start.

The helper parsed that empty stdout, so all five subtests in the
"state validate resolves bracket phase DIRECTORIES" suite failed identically
with `SyntaxError: Unexpected end of JSON input` at the JSON.parse, masking
what they actually assert.

Dropping the token restores the same envelope the helper already parsed. No
assertion changes. Verified against the fixture the suite builds: exit 0, and
the output carries the S005 plan-count warning the drift assertions require
with no S004 phase-directory warning — i.e. the bracket directory resolves,
which is the behaviour these tests exist to pin. 94/94 in the file.

* fix(#2761): exempt the phase-counting suite from the docs-guard lane

Surfaced by the rebase onto next. #3753 (107eb8c1d) added
lint-docs-guard-registration, which requires every test file that reads a
docs/ path to be either registered in the docs-guard lane or carry an
explicit marker. It flags adr-612-bracket-phase-counting.test.cjs, which
reads no docs/ path at all.

The file's only docs/ occurrence is the ADR-612 Decision 1 citation in a line
comment; every read call it makes targets a tmpdir .planning fixture. It trips
Detector 3, whose DOCS_TEMPLATE_LITERAL_RE sees an odd prose backtick in the
comment block above that citation as opening a template literal and reads the
span between them — citation included — as a docs/ path expression. That
detector documents this trade in its own header: it favours recall, and says a
false positive costs one docs-guard-exempt marker with a reason. The baseline
records the same class ("comment-only mentions") for 46 of its entries.

Registration was the wrong side of the trade here: it would run this suite in
the docs-guard lane on docs/ changes whose content it never reads.

Three pieces, matching what the gate requires and what its 54 existing entries
already do:
  - the marker in the file's header window, written without backticks so it
    cannot itself disturb the parity tracking findExemption does;
  - the basename in DOCS_GUARD_EXEMPT_BASELINE, since the ratchet fails a new
    marker until the baseline is deliberately updated — the reviewable diff is
    the point;
  - the FIX 3 per-file fingerprint, derived with the lint's own
    extractDocsPathReferences rather than retyped, so the exemption fails loudly
    if the set of docs/ paths this file mentions ever changes.

Gates: lint-docs-guard-registration 0 violations, ci-docs-guard-registry 51/51.

* docs(#2761): correct the bare-0 comment and state what opting into bracket costs

Round-13 review items Minor 2 and Minor 3, both still live on the previous head.

Minor 2 — src/phase-id.cts. The comment block claimed "Bare `0` is admitted
alongside it because a 0.x sentinel is a legitimate identity that predates
padding", which contradicted both the shipped constant and its own next
paragraph. BRACKET_CANONICAL_NUMERIC_SOURCE is `(?:[1-9]\d{2,}|\d{2})`;
measured against it, `0` is rejected while `00`, `05`, `99`, `100` and `999`
are admitted. The paragraph four lines below already recorded the removal
("the earlier `(?:\d{2,}|0)` ... admitted ... a bare `0` that pad2 never
produces"), so the block asserted and denied the same fact. The stale sentence
is replaced with what ships: `00` is the backlog sentinel's canonical padded
identity, `\d{2}` already covers it, and nothing needs the unpadded spelling.
No behaviour change — the constant is untouched.

Minor 3 — docs/CONFIGURATION.md. The phase_id_convention row described the
read-path widening but never said what a repo GIVES UP by opting in. Added:
on a bracket repo a heading whose bracket is followed directly by a digit is
read as a phase heading, so `### [RFC.2119] 5:`, `### [v1.0] 2024:` and
`### [ADR.612] 3:` — legal prose headings under any other convention — are
claimed as phases and move phase_count, total_phases and W006. Those three
shapes are the ones phase-id.cts's own selector comment names as the reason
the widened read is selected at construction time from this value rather than
applied everywhere; the row now carries that trade instead of only its
upside.

Gates: tsc --noEmit exit 0, npm run lint:ci exit 0, npm run test:unit
33890/33891 with the single failure being emitted-attribution's base drift
against a next that moved after the rebase (133/133 against the rebase base;
this push re-bases onto the current tip, which resolves it).

* chore(#2761): give this slice its own changeset and document the membership scoping

PR-2 (#2867) merged separately, so the completion-seam entry no longer
belongs appended to its fragment. Restore .changeset/2761-bracket-read-tolerance.md

* docs(#4142): cite #4142 in the completion-seam changeset backlink

The fragment's trailing backlink named #2761 — the delivered PR-2 sibling
whose ratified scope excluded this completion seam — rather than #4142,
the issue this PR actually closes. The PR body already carries the correct
`Closes #4142` with `Refs #2761` for lineage; only the changeset disagreed.

Backlinks are a convention rather than a machine-checked field, so
changeset-lint passed on the wrong citation.

* docs(#4142): name phase complete and workstream-inventory in the unthreaded-caller disclosure

Round-4 review Major. The changeset's "still unthreaded" list named only the
aggregate scans (uat, audit, init projections, gap-checker, phase-locator) and
omitted two call sites that also stay on the include-everything fail-safe for
bracket directories after this PR:

- cmdPhaseComplete (src/phase.cts:3394,3405) — `phase complete`'s advisory
  UAT and VERIFICATION warning pre-scan calls scopeToPhase two-arg, so a
  bracket phase can still be warned about a cross-phase stray it does not own.
- src/workstream-inventory.cts:663 — calls isPhaseComplete, which this PR
  made convention-aware, without resolving a convention to pass it.

Because roadmap.cts's write path WAS threaded here on ADR-3180 section 7.4
read/write symmetry, leaving `phase complete` off both the code and the
disclosure was the omission most likely to be read as covered by "the same
protection #3511 already gives legacy directories". That claim is now scoped
to the call sites this PR threads, in both the changeset and the shipped
docs/CONFIGURATION.md cell, which carried the identical omission.

Disclosure only — no production code changed. Threading these two remains
follow-up-slice work alongside the epic's other convention-less readers.

bbc3f131be refactor(#4653): make containment ONE decision, resolved two ways
Satisfies #4653 DW1 and DW9, which were the phase's outstanding acceptance
criteria: every other implementation must be deleted or route its containment
DECISION through the canonical predicate, and no surviving wrapper may decide
WHETHER a path is contained.

Three implementations were being retained with their own comparisons, on the
argument that each needs LEXICAL resolution — a realpath-based predicate is the
wrong tool wherever a symlink must be preserved rather than resolved. That
argument is correct about RESOLUTION and was being used to justify owning the
DECISION too. Those are separable, and separating them is what closes the
criteria honestly rather than by reinterpretation.

  isContainedIn(resolvedTarget, resolvedRoot, pathImpl?)   module-internal

is now the single place this repo decides containment. It is separator-aware, so
a sibling merely sharing a prefix (`<root>-evil` against `<root>`) is still
rejected. Two exported families sit on it and differ ONLY in how a candidate is
resolved before the decision:

  assertWithinRoot / tryWithinRoot                realpath-resolving
  assertWithinRootLexical / tryWithinRootLexical  path.resolve only, no I/O

The lexical pair carries `opts.pathImpl`, so win32 separator semantics stay
testable off Windows — that seam already existed in isPathConfined and would
have been lost by a naive collapse.

The three call sites now take their decision from the predicate and keep only
what is genuinely theirs:

  external-descriptor-trust isPathConfined   delegates outright; pathImpl forwarded
  installer-migrations ensureInsideConfig    delegates; keeps its own message and
                                             its LEXICAL fullPath, which callers
                                             consume for existsSync and journal rows
  gsd-tools.cjs isInsideDir                  delegates; keeps its own `target !==
                                             root` condition, and the separate
                                             symlink refusal above it stands

DW5 is not weakened by this. That criterion binds the symlink oracle and the
ancestor canonicalization; both are untouched. The only change inside
validatePath is three comparison lines becoming one call, and the rejection
string `Path escapes allowed directory: <resolved> is outside <base>` stays
byte-identical because it is an observable CLI contract.

What this does NOT do, stated plainly: the lexical family still cannot see a
symlink. That is a property of lexical resolution, not a gap in the seam, and
the three callers that need it are the three that must pair it with their own
symlink refusal — which is exactly what the fix earlier in this phase added at
the install sites. The doc comment says so at the definition, and CONTEXT.md and
docs/explanation/security-model.md are corrected: they previously described
these three as deliberately NOT routed through the predicate, which is no longer
true.

6f0e5ccf85 fix(#4636,#4653): close the symlink hole, revert a wrong collapse, fix six review findings
The RED checkpoint and two orthogonal reviews found eight defects. All fixed here.

THE COLLAPSE THAT WAS WRONG — installer-migrations. Routing ensureInsideConfig's
containment decision through the realpath-based canonical predicate broke four
tests, and the failure message says it plainly: "migration path escapes
configDir: extensions/gsd.cjs". That module's entire contract is that a
symlinked managed path is snapshotted, restored and backed up AS A LINK and
never dereferenced. The canonical predicate dereferences, then rejects the
result for escaping configDir — so it destroys exactly the thing the module
exists to preserve. Reverted to lexical, with the ruling recorded above the
function so it is not collapsed a third time. normalizeRelPath is the real
pre-gate there; it throws on absolute paths and '..' before this check runs.

That makes THREE deliberately-retained implementations, not two, and they share
one shape worth naming: a realpath-based predicate is the wrong tool wherever a
symlink must be PRESERVED rather than resolved. CONTEXT.md and
docs/explanation/security-model.md are corrected — both previously described
ensureInsideConfig as collapsed.

THE MISSED CONSUMER. tests/security-prompt-injection.security.test.cjs
destructures validatePath from the compiled lib; un-exporting it turned five
tests into TypeError. It appeared in my own earlier search output and I did not
follow it up. Translated under the same rule as the rest: assertions on the
rejection REASON go through assertWithinRoot, boolean-only through
tryWithinRoot.

VALIDATE-ONE-PATH-USE-ANOTHER, FOUND TWICE MORE. This is the fourth and fifth
occurrence in this epic of the exact defect it exists to prevent.
  - scripts/check-glossary-refs.cjs decided containment on `token` and then
    stat'd a separately re-joined path.join(ROOT, token). The ContainedPath is
    now carried through to the probe, so the validated value is the probed one.
  - src/init.cts computed skillPathContained and DISCARDED it, re-joining from
    the raw input for the existsSync and read. The branded type exists to make
    that a type error and here it was inert.

AND THE OVER-CORRECTION OF THAT FIX, caught before it shipped. The first attempt
also substituted the validated value into the EMITTED `ref` for a global skill.
That value is a display token, not a path anything reads through — the only fs
access in that branch runs on the lexical path beforehand — so substituting it
changed emitted output two ways: it is realpath-resolved, so a symlinked global
skills directory would have emitted its resolved target instead of the user's
own path, and it came from path.join, so Windows would have emitted a backslash
where the template has a literal '/'. Restored, with the distinction recorded:
the containment check there is a GATE, not a path producer.

A TEST THAT COULD NOT FAIL. The first symlink regression planted its symlink
from inside a hooked fs.readdirSync and never asserted the planting happened —
if the hook did not fire, the "nothing was written outside" assertion passed
trivially, green against vulnerable code. It now asserts the plant, matching its
sibling. The other two were re-checked: one already asserted its equivalent, the
other plants synchronously and cannot silently no-op.

THE SYMLINK FIX ITSELF, now that the tests are proven red on the matrix.
isPathConfined is lexical by design and structurally cannot see a symlink; three
callers relied on it with no defense of their own. install-engine.cts:1608 and
install-profiles.cts:880 refuse to mkdir/write through a link — mkdirSync with
recursive:true does NOT throw on an existing symlink-to-directory, so a planted
link redirected the SKILL.md write outside the install root.
install-profiles.cts:755 refuses to read through one — statSync FOLLOWS links,
so an outside file's contents were returned and installed as a skill body. Each
mirrors the guard retired-artifact-cleanup.cts:77 already uses.

Severity stated accurately rather than dramatically: only the read at :755 needs
no race. _removeGsdEntries sweeps a pre-planted link at :1608 before the write
loop, and :880's stageDir is a fresh mkdtemp, so both of those require winning a
window. They are fixed as defense-in-depth, not as live exploits.

ALSO: the Changed changeset claimed "every command's observable behavior [is]
unchanged". Three rejection messages are reworded. It now says so, and says that
none of them reveals a host path it previously hid. A stale comment in
verify.cts still named validatePath; an init.cts warning hardcoded "resolves
outside the project directory" for a check that also rejects absolute paths, NUL
bytes and empty strings; and the rationale deleted with check-glossary-refs'
retired helper is restored, noting honestly that a rejected token is now
realpath-resolved before rejection rather than rejected by string comparison.

5967f1939a docs(#4653): record the path-containment seam in CONTEXT.md and add the changeset
The glossary had no entry for the containment predicate at all, which is the
epic's actual deliverable. The new entry states the engine/export split, the
branded type, the named acceptance policy, the preserved message contract, and
— the part most likely to be undone by a later cleanup — the two
implementations deliberately NOT collapsed and why each is stricter or
narrower rather than duplicative.

Glossary gate re-run: 269 refs, exit 0. Install-tree goldens regenerated and
confirmed byte-identical rather than assumed unchanged; lint:ci exits 0, so no
conformance-tier drift either.

374300da17 fix(#4652): confine every boundary that joins argv to a managed root
Phase 2 of epic #4636, absorbing #4327 and #4354. Implements ADR-4650
decision 3: containment is a boundary concern — the predicate runs where
external input enters, not at whichever interior call site remembered.

Four boundaries now validate against their managed root and reject with a
USAGE-shaped error before touching the filesystem:

  todo complete <name>                 -> todosDir(cwd)
  check predicate --phase-dir <dir>    -> projectDir
  check decision-coverage-plan <dir>   -> projectDir   (via resolvePath)
  check gap-analysis.plan-post <dir>   -> projectDir

#4327 understated its own severity. It reports that a traversal name
"resolves outside the todos root", which reads as an information leak.
Measured, it was destructive: the command exited 0, MOVED the outside file
into completed/, and unlinked the original. cmdTodoComplete ends in
fs.unlinkSync(sourcePath), so an unconfined name consumed across the
boundary rather than merely reading across it. Validation now precedes every
fs call — existsSync, readFileSync, ensureDir, writeSync, unlinkSync — and
both halves of the move are confined, so neither source nor destination can
land outside the root. --dry-run is rejected on the same terms; a preview
must not leak a resolved outside path either.

#4354 reproduces exactly: a BLOCKING gate returned block:false sourced
entirely from a SECURITY.md in a caller-chosen directory outside the project.

THE HARDER HALF, found by the isolated adversarial review of the first
attempt: validating a path and then using a DIFFERENT one closes nothing.
The first fix validated `--phase-dir` joined against `--cwd`, then passed the
RAW unjoined value into the predicate context. gate-predicate-evaluator uses
it as-is and findPhaseArtifact resolves a relative path against the REAL
process cwd — so validation and the read used two different roots whenever
process.cwd() differed from --cwd. Reproduced: running from a directory
holding a plan with `secret_field: LEAKED_VALUE`, a predicate declared
against an empty --cwd project exited 0 and returned "actual":"LEAKED_VALUE".

The rule now applied at all three router sites: **use the validated resolved
path, never the raw input.** Independently re-verified after the fix — the
lookup resolves in the --cwd project and no value leaks.

gate-predicate-evaluator.cts is untouched and still imports no fs. Confining
in the router is what keeps that pure-leaf contract intact AND covers
${PHASE_DIR} interpolation into command-exit-zero, which an evaluator-local
fix would have missed entirely.

Also fixed, same review: `todo complete .` and `..` passed containment
(they resolve to the pending dir, which IS inside the root) and then threw an
uncaught EISDIR with an absolute-path stack trace. Now a clean USAGE
rejection naming the real reason — "todo name is not a file" — rather than
borrowing the escape message, which would have stated something false.

Ripples discharged BEFORE the verification checkpoint rather than after, per
the Phase 1 retrospective: docs/reference/gate-predicates.md and
docs/CLI-TOOLS.md document the new constraints, CONTEXT.md records why
containment lives at the router rather than the evaluator, the changeset is
written, and the install-tree goldens were regenerated to confirm unchanged
(no new shipped file) rather than assumed.

38e4ce5f62 fix(#4186): anchored status vocabulary, record-session arg guard, recount pin (#4381)
* fix(#4186): anchored status vocabulary, record-session arg guard, recount pin

Three defects from #4186:

1. normalizeStateStatus ran a first-match-wins SUBSTRING chain over the
   free-prose body Status field, so prose merely mentioning a status word
   was silently rewritten to a credible wrong token (a .planning/ path in
   Italian prose -> status: planning; verifica -> verifying; completezza ->
   completed). Recognition is now an ANCHORED whole-field match against a
   declared vocabulary (STATUS_EXACT_TOKENS + STATUS_ANCHORED_PATTERNS,
   state-document.cts) — case/whitespace-tolerant, branch-order artifacts
   preserved (Planning complete -> planning; Phase complete — ready for
   verification -> verifying). The recorded lenient fallback (#3873 row 26)
   stands: unrecognized prose passes through verbatim. Read-side consumers
   (W011, statusline) ride the same function.

2. The progress recount skew (stray *-SUMMARY.md inflating
   completed_plans) is already dead on next via #1988/PR #2016
   (countMatchedSummaries pairs summaries to plans) — verified live and
   pinned with regression rows composed against the #4129/#4359 ratchet.

3. state record-session with no args executed and wrote STATE.md; it now
   errors like state update (stopped-at or resume-file required), handler-
   side so SDK callers are covered too. Four tests pinning the bare-call
   write are updated to the new contract.

* fix(#4186): update status pins to the anchored vocabulary contract

Bench round 1 follow-ups:

- Legacy bare 'Milestone complete' kept as reader-side vocabulary
  (ADR-2207 removed the writers, not recognition of legacy files).
- state.test pins updated: 'Paused at Plan 3' and round-trip
  'Executing Plan 5' were pins of the substring guessing itself —
  the round-trip now uses the real handler form 'Executing Phase 5'.
- record-session no-op/no-fields tests repurposed to the usage-error
  contract (CLI + SDK-level ExitError), byte-unchanged assertions kept.
- statusline tests repinned: vocabulary values collapse to keywords;
  narratives render the documented first-word fallback instead of a
  guessed token. Hook doc comment updated to match.
- docs-guard exempt baseline: state.test.cjs now cites docs/CLI-TOOLS.md.
- docs/CLI-TOOLS.md: record-session signature notes the required flag.

c3e2da153b fix(#4134): refuse punctuation-only milestone heading names (#4358)
* test(#4134): fail-first regression — refuse punctuation-fragment milestone names

A first-milestone ROADMAP.md H1 that puts the version after the name
(# Roadmap: Project — Name (v1.13)) leaves exactly ')' after the heading's
own version token, which the ADR-3180 §7.2 pinned name rule returns as a
COMPLETE-scope milestone name. Failing-first coverage:

- getMilestoneInfo: name-then-version H1 (STATE-anchored + ROADMAP-only
  fallback) must yield TRUNCATED {version, name: null}, never ')'
- the refusal is level-agnostic (H2/H3)
- punctuation-family remainders (')', '()', '**', '.,;:', ']}', emoji-only)
- listMilestoneHeadings enumerates the heading with name: null
- init manager CLI reports milestone_name: null and no lone ')' anywhere
- property (seed 20260905, 300 runs): a word-char remainder is always a
  name, a punctuation-only remainder never is
- negative space: canonical delimiter forms, parenthetical names (#3171),
  trailing markers, digit-only names, CRLF headings, version-last-no-parens
  control

* fix(#4134): refuse punctuation-only milestone heading names

extractMilestoneHeadingName returns everything after the heading's own
version token as the name (ADR-3180 §7.2 pinned rule), which assumes
version-then-name. A name-then-version heading — the H1 a first-ever
ROADMAP.md drifts into ('# Roadmap: Project — Name (v1.13)') — leaves
exactly ')' after the token, and that fragment was returned as a
COMPLETE-scope milestone name, propagating into init.* JSON output and
buildStateFrontmatter's STATE.md writes.

A remainder with no letter or digit anywhere (any script) is heading
structure, not a curated name: refuse it as name: null so callers report
the honest §7.2 rule-6 answer (version kept, TRUNCATED scope). Names
that merely contain punctuation are unaffected — '(' stays an ordinary
name character (#3171) — and digit-only names qualify.

Also closes the template gap that lets the shape occur: the roadmapper
agent's output_formats now templates the version-free canonical H1
('# Roadmap: [Project Name]', per templates/roadmap.md) instead of
leaving a first milestone's title line to invention. The new section
shifts the file's existing bare-gsd-tools prose mention from line 647
to 660, so its line-keyed PROSE_ALLOWLIST entry moves with it.

Emitted-Drift-Ack-Growth: gsd-roadmapper.md — deliberate +498 bytes: new '### 0. Top-Level Title (H1)' output_formats section templating the canonical version-free H1, closing the first-milestone template gap that lets an H1 drift into 'Name (vX.Y)' and corrupt milestone_name extraction (#4134)

* fix(#4213): keep STATE.md progress surfaces synchronized

* fix(#4213): clamp the shared progress bar and keep bold-first priority, changeset + property tests

- formatProgressMachineSegment clamps through clampPercentFromFraction
  (ADR-3180 Decision 7 kernel) with a 0 floor, so a hand-edited
  out-of-range persisted percent renders a clamped bar instead of
  throwing RangeError on repeat() inside the write seam
- stateReplaceProgressPercent restores the #2177 bold-first priority:
  **Progress:** anywhere in the body wins; a plain ^Progress: line is
  the fallback, so free text starting with Progress: cannot capture
  the rewrite ahead of the real status line
- cross-reference comment names the three consumers and the
  cmdStateSync sanctioned exception (ADR-3408 §8.3)
- CONTEXT.md: applyPostSyncPreservation reconciliation documented in
  the STATE.md Transition Module entry
- property tests (never-throws/well-formed, idempotency, round-trip,
  bold-first) + two regression rows through the CLI

5869febb16 enhance(#4155): invalidate verification results when covered inputs change (#4290)
* enhance(#4155): invalidate verification results when covered inputs change

readVerificationStatus() now recomputes a deterministic sha256 fingerprint
over a VERIFICATION.md's declared covered_files (phase PLAN/SUMMARY,
requirements, implementation files in the verified change set) and returns
stale on any mismatch, fail-closed when a covered file is missing,
unreadable, or escapes the project root. Legacy reports with no fingerprint
metadata keep the prior SUMMARY-mtime staleness check unchanged.

The verifier computes covered_digest via the new verification.fingerprint
CLI command rather than by hand, since a digest is deterministic math, not
an LLM-estimated value.

* chore(#4155): backfill fork PR number in changeset

* fix(#4155): trim gsd-verifier.md fingerprint instructions to fit LARGE tier byte cap

* fix(#4155): address CodeRabbit findings on fingerprint fail-closed behavior

Partial fingerprint metadata (one of covered_files/covered_digest present,
the other missing or malformed) now fails closed to stale instead of
silently downgrading to the legacy mtime-only check. computeCoveredDigest
also canonicalizes with realpathSync before re-confining, so an in-root
symlink whose target escapes the project root can no longer produce a
matching digest. gsd-verifier.md restores the completeness requirement and
checklist item trimmed by the earlier size-budget fix, within the LARGE
tier byte cap.

* chore(#4155): acknowledge gsd-verifier.md growth for the #4155 fingerprint instructions

Emitted-Drift-Ack-Growth: gsd-verifier.md — adds the covered-input fingerprint instructions and frontmatter fields the #4155 verification staleness mechanism requires; trimmed to stay within the LARGE tier byte cap

* fix(#4155): address gemini adversarial review findings

computeCoveredDigest now threads the caller-supplied opts.fs seam through
its confinement and read paths instead of always using raw node:fs — a
caller like planning-inspect.cts's containmentEnforcingVerificationFs (GAP
2, #2790 follow-up) was silently bypassed for covered-input reads. The
project-root anchor itself still canonicalizes through real fs (it is a
trusted value the caller derived, not attacker-influenced covered-input
data); only per-file candidate reads go through the injected seam.

Covered-file paths are now canonicalized (./ prefixes, redundant slashes,
internal .. segments) before becoming dedup/sort/hash keys or confinement
subjects — closes both a spurious-stale false positive (two spellings of
the same file hashing differently) and a confinement gap (an internal ..
segment that doesn't start the string).

gsd-verifier.md now states covered-file paths are project-root-relative,
not phaseDir-relative, closing an ambiguity that would have made a real
verifier agent's first fingerprint invocation fail closed.

defaultFsImpl's methods now late-bind through fs.<method> rather than
capturing function references at module load — the earlier direct-capture
form was invisible to existing tests' t.mock.method(fs, 'statSync', ...)
seams, a real regression caught by the full suite (not the reviewer).

* fix(#4155): catch a plan/summary added to the phase dir after verification but never declared

The content digest only recomputes hashes for paths the verifier actually
declared in covered_files — it had no way to notice a plan or summary
added to the phase directory after verification if that new file was
never declared, silently regressing behind the legacy mtime check it
replaces (which scans the live directory, not a declared list).

findUncoveredCurrentArtifact re-scans the live phase directory for every
current *-PLAN.md/*-SUMMARY.md and requires each to be represented in
covered_files, closing that gap; a directory scan failure fails closed to
stale rather than silently skipping the check.

CONTEXT.md's Verification Module entry corrected to describe the
fingerprint path's stricter fail-closed FS-error contract (routes to
stale) instead of the module's original degrade-to-safe one (missing /
not-stale), which only the legacy path still keeps.

* refactor(#4155): extract canonicalizeCoveredFiles, add real nested-project e2e test

computeCoveredDigest and cmdVerificationFingerprint each normalized/deduped/
sorted covered_files independently — one shared helper now backs both
(gemini review's ponytail-lens finding).

Adds one CLI-to-readVerificationStatus test against a genuine
.planning/phases/NN-x/ project with an implementation file outside
.planning/ entirely, closing the review finding that prior #4155 unit
fixtures put phaseDir directly under an ownerless tmpdir (findProjectRoot
falls back to phaseDir itself there) and never exercised real multi-level
path resolution.

* fix(#4155): route computeCoveredDigest through real fs, fail closed on unreadable plans/

Two independent review rounds (opus critical-reviewer + opus ponytail +
agy, run twice) found two instances of the same fail-open class:

- computeCoveredDigest's per-file reads routed through the caller's
  injected fsImpl. planning-inspect.cts passes a `.planning/`-confined
  containment fs into readVerificationStatus's opts.fs, so any covered
  implementation file outside `.planning/` (mandatory per the issue)
  made the confinement wrapper throw, which was caught and turned into
  a stale digest -- reporting every fingerprinted phase permanently
  stale via `planning.inspect`, regardless of actual drift. Per-file
  reads now always use real node:fs, matching the pre-existing
  treatment of root canonicalization; the realRel-vs-realRoot check is
  the real confinement boundary for this data and needs no seam.

- allCurrentArtifactsCovered's try/catch never fired (scanPhasePlans
  reports readdir failures via a `scope` field, it never throws), so
  an unreadable nested plans/ dir was silently treated as "zero
  artifacts, all covered" instead of failing closed. Now branches on
  scope !== SCOPE.COMPLETE.

Also, per ponytail's second-round findings: reverted an unwarranted
FINGERPRINT_VERSION bump and digest length-prefix from the first fix
(no v1 digest has ever existed -- the feature is unreleased -- and the
prefix closed a collision that grants no capability beyond what a
writer of covered_files already has more cheaply); removed a
verifier-facing escape-hatch instruction whose own example was a case
that should trigger staleness, not bypass it; corrected CONTEXT.md
references to the renamed allCurrentArtifactsCovered and a stale
"unconditional" rescan claim; simplified the isStale derivation,
removed dead FsLike members, and tightened test coverage.

Regression tests for both fail-open bugs are included and were each
confirmed to fail against the pre-fix code before the fix landed.

full test suite: 2558/2560 pass, 2 skipped, 0 fail

* fix(#4155): trim gsd-verifier.md under the LARGE size cap

Fork CI caught what my local runs missed: the superseded/nested-plans
instruction added earlier pushed gsd-verifier.md to 49299 bytes,
147 over the LARGE tier's 49152-byte hard cap
(tests/agent-size-budget.test.cjs). Tightened the #4155 instruction's
wording and dropped a redundant inline comment tag; no content lost.

* chore(#4155): point changeset at the upstream PR number

pr: 19 was the fork PR opened for internal review-lane CI; now that
open-gsd/gsd-core#4290 exists, the changeset field must match it per
CONTRIBUTING.md's release-notes convention.

* test(#4032): expose fork review regressions

* fix(#4032): address fork review findings

* test(#4032): make byte-stability assertion portable

Compare repeat installs at one root so platform-specific path rendering cannot
masquerade as an agent_tools behavior change.

* chore(#4032): bind changeset to upstream PR 4238

* fix(#4032): address trek-e review findings (2,3,4,5,6,7,8)

Fixes fail-closed decode-failure handling in ZCode's mcp__ stripper,
a comment-only `tools:` header mis-parse that silently dropped
configured grants, and a naive comma-split that could tear a quoted
scalar containing a literal comma. Documents Kilo's inherent
`{server}_{tool}` MCP-permission-key collision (external, fixed
format — not ours to widen) and locks the existing first-seen-wins
resolution in with a regression test.

Opts kimi/kimi-code out of the ADR-1235 pre-converter path-rewrite
step: routing Kimi through that pipeline (needed so project-scoped
agent_tools selectors reach it) was short-circuiting Kimi's own
neutralizeKimiAgentPrompt, which expects the original ~/.claude/gsd-core
text rather than a pre-rewritten Kimi path.

Extends the fast-check token pool and per-runtime install coverage
with the missing comment/comma/broad-runtime cases the prior review
flagged as untested.

* docs(#4032): add CONTEXT.md glossary entries for agent_tools resolver + pre-converter step

Documents readGsdEffectiveAgentTools (Install Model Override Resolver
Module) and the appendAgentTools pre-converter pipeline step (Runtime
Artifact Conversion Module), per contributor-standards.md's
new-seam glossary requirement (finding 1).

* fix(#4032): address agy adversarial review findings

An agy (gemini-3.8-flash-high) adversarial pass over the prior review-fix
commit found the fixes for findings 3, 4, 6 and 8 had unfixed sibling gaps,
plus a genuine new regression and two CONTEXT.md inaccuracies:

- ZCode's comment-only `tools: # note` header matched the inline-value
  branch instead of falling through to the block-list scan, so a following
  mcp__* item leaked through unstripped — the exact defect finding 4 fixed
  in appendAgentTools, unfixed in this sibling function.
- Reverted capabilities/kimi-code/capability.json's noPathRewrite: true.
  kimi-code uses the standard 'agents' kind with converter: null (not
  kimi-agents — confirmed by reading the descriptor, not its prose
  description), so it never went through the pipeline change finding 5
  fixed, and disabling its path rewrite broke every ~/.claude/ embed in
  its shipped agents instead.
- decodeToolScalar never stripped a trailing ` # comment` from a bare
  (unquoted) scalar, so a comment after a block-list item, or after an
  appended grant on an inline line, became part of the "tool name" —
  fixed at the source (one call site fixes every consumer).
- appendAgentTools's comment-index scan wasn't quote-aware, so a `#`
  inside a quoted scalar (`"mcp__server #1"`) was mistaken for a comment
  start and corrupted the quote.
- parseFrontmatterTools (Kimi/Qwen's tool-list reader, downstream of
  appendAgentTools's own output) had the same naive comma-split and
  comment-only-header gaps as findings 4 and 6, unpatched.
- The all-runtime smoke test's presence assertion was built on a guessed
  omit-list; empirically only 7 of 17 runtimes keep an arbitrary mcp__
  grant recognizable, replaced with a verified allowlist.
- CONTEXT.md claimed a `project:<agent>` selector prefix that does not
  exist (project override is a same-key merge across two config files)
  and mislabeled stageAgentsForRuntimeWithConverter's module.

* fix(#4032): address full-PR review (Opus critical/ponytail + agy)

A whole-PR pass (critical-code-reviewer + ponytail-review on Opus, plus a
second agy full-source adversarial pass) surfaced defects the earlier
finding-scoped passes couldn't reach:

- appendAgentTools corrupted a `tools:` line whose ENTIRE value is a
  leading quoted scalar (`tools: "Read"` -> `tools: "Read", Write`,
  invalid YAML) — there is no safe line-surgical rewrite here, so it now
  refuses to touch that shape instead of emitting broken frontmatter.
- decodeToolScalar's malformed-trailing-quote check ran BEFORE comment
  stripping, so a bare tool name with a quote inside its own trailing
  comment (`Bash # note: "internal"`) was wrongly rejected. Reordered.
- findUnquotedCommentIndex (added in the prior remediation commit) was
  built on a wrong model of YAML: a `#` after whitespace starts a real
  comment in a plain scalar regardless of nearby quote characters —
  verified against the actual parser. The one case that DOES need
  protection (a leading quoted scalar) is now refused outright above, so
  the quote-tracking scan was dead weight solving a problem that no
  longer reaches it. Removed; reverted to the plain `[ \t]#` scan.
- Kilo has a SEPARATE agent-frontmatter parser (convertClaudeToKiloFrontmatter,
  distinct from the buildKiloAgentPermissionBlock fixed earlier) with the
  same comment-only-header and naive-comma-split gaps as findings 4 and 6
  — unfixed in both its src/ and bin/install.js copies. Fixed in both,
  exporting splitToolScalars for bin/install.js to reuse rather than
  reimplementing it.
- Pipeline docstring in stageAgentsForRuntimeWithConverter still listed 5
  steps, omitting appendAgentTools (now step 3 of 6).
- docs/CONFIGURATION.md didn't state that a --global install still
  discovers agent_tools from the cwd's .planning/config.json (confirmed
  intentional and already covered by a dedicated test, not a bug).
- Removed install-engine.cts's deps.cwd injection seam: zero callers or
  tests ever populated it.

Two claims from this round were verified and rejected, not fixed:
prototype pollution via a `__proto__` selector key (empirically confirmed
`Object.prototype` is never touched — only reassigns the resolver's own
local object's prototype, with no observable effect), and a `*` grant
value crashing YAML parsing as an alias reference (empirically confirmed
it parses as plain scalar text, no crash). A pre-existing, unrelated
defect (extractFrontmatterField returns null for block-list `tools:` on
Copilot/Antigravity/Cursor/Codex/Qwen, affecting two shipped agents
today) was filed as a follow-up rather than fixed here — it predates
#4032 and isn't caused or worsened by this PR.

* fix(#4032): update stale slug-derivation-drift-guard fixture line

normalizeKimiSkillName's real closing brace moved from line 616 to 635 as a
side effect of this PR's edits to runtime-artifact-conversion.cts; the
MAJOR-1 fixture's hardcoded realEndLine had gone stale.

* fix(#4032): address CodeRabbit findings on projectDir threading and flow-sequence tools

bin/install.js's installAgentsKindStandalone call site omitted the projectDir
argument the function already supports, so a global install through this
legacy branch silently fell back to the runtime config dir instead of
process.cwd() when resolving project-scoped agent_tools grants — inconsistent
with the sibling installOpencodeFamilyArtifacts call site, which already
threads it correctly.

appendAgentTools' leading-quoted-scalar bailout did not cover a YAML flow
sequence (`tools: [Bash, Read]`): splitToolScalars tore it apart on the
in-sequence commas and appended past its closing bracket, producing invalid
frontmatter. Extended the bailout regex to also refuse a value starting with
`[`, matching the same "whole node, nothing may follow" reasoning already
applied to quoted scalars.

77e2472ca0 enhance(#4221): replace installer Read() deny rules with a managed secret-read guard hook (#4236)
* feat(#4221): gsd-secret-read-guard PreToolUse hook + registration

Add hooks/gsd-secret-read-guard.js, a blocking PreToolUse guard on
Read|Grep|Bash that denies reads of .env, .env.<suffix> and .secrets
(the .env.example/.sample/.template/.dist templates stay readable).
Read checks file_path; Grep checks an explicit path and judges the glob
per brace alternative; Bash runs a two-pass token scan (quotes, comments,
redirects with fd digits, separators, $( )/backtick/<( ) recursion,
heredoc bodies never scanned as commands, nested bash -c/eval rescans,
git <ref>:<path> shapes) with a closed non-reading exemption set for
existence checks. Fail-open crash policy; 1 MiB commands are denied as
command-too-large; more than 64 glob alternatives as glob-too-complex.

Why: Claude Code 2.1.259 makes every `cd DIR && grep …` compound prompt
for approval whenever any Read() deny rule exists, even in auto mode. A
hook denial is not a permission rule and never arms that check. The
installer-written deny rules are retired in the follow-up commit.

Registration: hooks.json (Read|Grep|Bash, timeout 5), build-hooks
HOOKS_TO_COPY, managed-hooks-registry, runtime-hooks-surface (blocking
guard with BLOCKING_GUARD_TIMEOUT_S; Kimi ReadFile|Grep|Shell),
shell-command-projection managed sets, installer-migration-report,
OpenCode/Kilo plugin (grep tool mapping, include -> glob, dispatch),
docs tables in five locales, ADR-766 always-on list, regen:derived
fixtures, and a new table-driven unit suite.

* test(#4221): pin the secret-read guard in existing hook gates

Register gsd-secret-read-guard.js in every existing hook gate: the
hooks-crash-policy table (deny row; 6 -> 7 deny cases), plugin-manifest
REQUIRED_HOOKS and its Read|Grep|Bash group, docs-hooks-table-parity
EXPECTED_SURFACE_HOOKS, install.test MANAGED_JS_HOOKS, install-minimal-
hooks JS_HOOKS/BLOCKING_GUARDS, portable-node-runner GUARD_HOOKS,
kilo-upgrades PLUGIN_GUARD_HOOKS, the Kimi normalization-parity and
typed-payload floors, the OpenCode adapter (grep mapping, include ->
glob, three dispatch tests) and a Kimi TOML matcher assertion.

* fix(#4221): retire installer Read() deny rules (legacy filter)

Rename GSD_CLAUDE_DENY_PERMISSIONS to GSD_CLAUDE_LEGACY_DENY_PERMISSIONS
and stop adding the three Read(.env) / Read(.env.*) / Read(.secrets)
strings. mergeClaudePermissions now only filters them out of an existing
permissions.deny: an absent deny key stays absent, a malformed one is
still repaired to [], and an array emptied by the filter is deleted so
no `"deny": []` residue is left. Uninstall filters the same legacy list
and, symmetric with the Antigravity branch, drops an emptied allow or
deny key and an emptied permissions object.

Unlike the #2278 allow-side migration there is no surviving current
deny list, so the constant is renamed rather than mirrored. Removal is
byte-exact: a hand-written identical rule is indistinguishable from the
installer's and is removed too (the manifest never recorded permission
strings). USER-GUIDE and CONTEXT.md updated.

* test(#4221): flip install-regressions deny-rule assertions to the retired shape

The fresh-merge, non-destructive merge, idempotency, end-to-end install,
reinstall and uninstall assertions now expect no Read(.env*) deny rules
and no permissions.deny key on a fresh install; the deny:null repair case
is kept. A new describe block covers the legacy filter: retired strings
removed with a user entry kept, partial sets, near-miss strings
untouched, idempotency, GSD-only deny array deleted, a pre-existing
empty deny preserved, and uninstall symmetry for allow/deny/permissions.

* chore(#4221): add changeset fragment for PR #4236

* fix(#4221): case-fold names; scan shell stdin and xargs pipes

Review round 1 (trek-e):

- Blocker: secret-name matching is now case-insensitive in the Read,
  Grep (path and glob) and Bash paths, so `.ENV` / `.Secrets` on a
  case-insensitive filesystem are recognized as the same secret file.
- Major: a shell interpreter's script is now scanned wherever it comes
  from. The tokenizer keeps heredoc bodies as per-segment tokens and
  records separator operators; pass 2 groups by segment id and resolves
  bash/sh/zsh/dash/ksh/su invocation mode: `-c` (including combined
  `-lc`) scans the script operand, a file operand is checked as a file
  (a `<( )` operand's echo/printf output is reconstructed), otherwise
  stdin is the script and heredocs, here-strings and a piped echo/printf
  source are scanned. `eval` joins all its operands; `source`/`.` handle
  process substitution. Data heredocs (`cat <<EOF`, the commit-message
  shape) stay unscanned.
- Major: `… | xargs <cmd>` checks the upstream segment's operands as
  file names when the sub-command reads (`echo .env | xargs cat`,
  `find . -name .env | xargs cat`); `-a`/`--arg-file` suppresses the
  inference; a shell sub-command's `-c` script is scanned.

Header, USER-GUIDE bullet and changeset updated; documented gaps now
include piped scripts from non-echo sources and `exec`/`timeout`
wrappers. 60 new suite cases pin the block and allow shapes.

2f64e6230a feat(#3676): quick-batch command, workflow, and isolation integration (#4212)
* test(#3676): add failing tests for quick-batch dispatch core

Failing-first tests for Phase 4 of epic #3344 (ADR-1239 "Quick-batch
binding"): quick-batch-dispatch.test.cjs / .property.test.cjs cover the
new pure decision-logic module (arg validation, effective concurrency,
deterministic merge order, spawn backpressure, verification/merge
routing, cleanup-entry construction — design doc rows 3-15,24,26-28,
30-36,39; property rows 51-53). quick-batch-update-items.test.cjs
covers the new updateBatchItems export on src/quick-batch.cts (rows
15,22-23, including the negative cycle-rejection case).
quick-batch-command-router.test.cjs covers the new
gsd-tools quick-batch CLI family (rows 46-47). These reference modules/
exports that do not exist yet.

* feat(#3676): implement quick-batch dispatch core, updateBatchItems, and command router

Phase 4 of epic #3344 (ADR-1239 "Quick-batch binding") CORE decision
layer — CLI verbs and pure orchestration logic only; no workflow
markdown, no Agent()/git-worktree I/O.

- src/quick-batch-dispatch.cts (new): pure decision functions consumed
  by the (separate, follow-up) /gsd:quick-batch workflow markdown —
  parseQuickBatchArgs, computeEffectiveConcurrency, computeMergeOrder,
  computeSpawnPlan, routeVerificationOutcome, routeMergeOutcome,
  buildCleanupManifestEntry (the last parses caller-supplied plan text
  via the existing parsePlanDocument; no filesystem access).

- src/quick-batch.cts: adds updateBatchItems, resolving the design
  doc's Open Question 1 as ONE additive export on this module instead
  of the second, independent BATCH.json writer the design doc
  originally proposed. Reuses the same withPlanningLock transaction
  shape, computeWaves, and platformWriteSync call resumeBatch/
  completeQuickItem already use; fails closed without persisting on
  an unknown item, an unknown/self dependency, or an introduced cycle.

- src/quick-batch-command-router.cts (new): gsd-tools quick-batch CLI
  family, wired into HOST_COMMAND_ROUTERS (gsd-core/bin/gsd-tools.cjs)
  as a first-party always-on command (like /gsd:quick), not the opt-in
  capability-registry path graphify uses. Verbs: create/update/resume/
  complete (wrap quick-batch.cts) and effective-concurrency/
  merge-eligible/spawn-plan/verification-routing/merge-routing/
  cleanup-entry/parse-args (wrap quick-batch-dispatch.cts).

Design doc rows covered: 3-15, 22-24, 26-28, 30-39, 46-47. Property
rows 51-53. Rows covering workflow markdown / Agent() dispatch /
`git worktree` behavior (16-21, 25, 29, 40-45, 48-50) remain for the
follow-up markdown-authoring pass, per the phase brief's explicit
scope boundary.

* docs(#3676): register quick-batch-dispatch/command-router modules in bookkeeping surfaces

New-.cts-module ripple for the two Phase 4 modules (epic #3344,
ADR-1239 "Quick-batch binding"): .gitignore (compiled .cjs artifacts,
ADR-457 build-at-publish), eslint.config.mjs (lint the .cts source,
not the emitted .cjs), docs/INVENTORY.md + docs/INVENTORY-MANIFEST.json
(via `node scripts/gen-inventory-manifest.cjs --write`, after
`npm run build:lib`), and CONTEXT.md glossary entries for
"Quick-Batch Dispatch Core Module" and "Quick-Batch Command Router
Module", plus an update to the existing "Quick-Batch Core Primitives
Module" entry documenting the new updateBatchItems export.

* test(#3676): fold updateBatchItems tests into quick-batch.test.cjs (fix lint-test-file-count)

scripts/lint-test-file-count.cjs buckets any quick-batch-*.test.cjs
file under the quick-batch production module by longest-prefix match,
and that module is already at its 2-file cap (quick-batch.test.cjs +
quick-batch.property.test.cjs). The standalone
tests/quick-batch-update-items.test.cjs added in the prior commit
pushed it to 3 and failed `npm run lint:ci`. Fold its content into
quick-batch.test.cjs (append-only — no existing test in that file is
modified) and update the CONTEXT.md glossary reference to match.

Surfaced while re-running `GITHUB_BASE_REF=next npm run lint:ci` after
`npm ci` (this worktree previously had no local node_modules, which
also made gen-scripts-cli-exit/gen-hooks-cli-exit/gen-exit-code-*
unable to resolve typescript — resolved by npm ci, no code change
needed there). `npm run lint:ci` and
`npx tsc -p tsconfig.build.json --noEmit` are both green after this
fix.

* test(#3676): add failing tests for the quick-batch command/workflow markdown

Failing-first tests for Phase 4's markdown-authoring pass (epic #3344,
ADR-1239 "Quick-batch binding"): gsd-quick-batch-workflow.test.cjs
covers commands/gsd/quick-batch.md's frontmatter/objective/process,
gsd-core/workflows/quick-batch.md's byte-size boundary (row 49, ADR
1610 NEW_FILE_CAP) and step-fragment count, the isolation model
(rows 20-22), the executor single-writer invariant (row 18), merge
validation reusing the existing bounded primitive (row 25), the
optional research/plan-checker/verification leaves (rows 16,17,19,
30,31), planning-failure blocking execution (row 29), the submodule
guard (rows 36,44), and the new agents/gsd-planner.md quick-batch
mode (rows 13-15). gsd-quick-batch-quick-regression.test.cjs covers
row 48 (ordinary /gsd:quick stays byte-identical). Named
`gsd-quick-batch-*` (not `quick-batch-*`) so lint-test-file-count's
longest-prefix bucketing doesn't fold these markdown-only tests into
the already-capped quick-batch/quick-batch-dispatch/
quick-batch-command-router production-module buckets from the CORE
pass. These reference files that do not exist yet.

* feat(#3676): author the quick-batch command, workflow, and planner mode

Phase 4 markdown-authoring pass (epic #3344, ADR-1239 "Quick-batch
binding") — the orchestration layer that calls into Pass 1's CLI
verbs (src/quick-batch-command-router.cts).

- commands/gsd/quick-batch.md (new): frontmatter/objective/process,
  delegates argument validation to `quick-batch parse-args`
  (parseQuickBatchArgs) rather than re-deriving the grammar.

- gsd-core/workflows/quick-batch.md (new, 11843 bytes — under ADR
  1610's 32768-byte NEW_FILE_CAP for a brand-new file) + 9 lazy-loaded
  step fragments under gsd-core/workflows/quick-batch/steps/:
  resume-mode, batch-init, research-phase (flag:--research),
  planner-wave (+ nested plan-checker-loop when --validate),
  worktree-dispatch, merge-wave, verification-wave (flag:--validate),
  completion. Covers design doc rows 3-45: capacity/isolation
  resolution (reusing dispatch-isolation-gate.md verbatim), per-DAG-
  layer planning with full-task-catalog prompts and always-required
  depends_on/files_modified frontmatter, serialized worktree create/
  merge/cleanup via the existing worktree.cleanup-wave primitive,
  deterministic wave-order merging, verification routing
  (human_needed/gaps_found), the executor single-writer invariant,
  submodule fail-loud guard, and #1941 fork-base auto-degrade.

- agents/gsd-planner.md: additive new `load_mode_context` bullet for
  `**Mode:** quick-batch`, pointing at the new
  gsd-core/references/planner-quick-batch.md reference (documents the
  always-required depends_on/files_modified contract, reusing the
  existing frontmatter grammar — no new keys). Existing modes
  byte-identical, only a new bullet added.

- src/init.cts (+init-command-router.cts, +command-aliases.cts):
  cmdInitQuickBatch / `init.quick-batch` — model profiles,
  commit_docs, roadmap/planning existence checks, and the
  section_manifest field gating research-phase/verification-wave
  (reuses the existing flag:--research/flag:--validate WHEN_VOCABULARY
  atoms — no new atom needed).

Rows 16-21, 25, 29, 36, 38, 39, 44, 46-50 covered structurally by the
prior test(#3676) commit; rows 3-15, 22-24, 26-28, 30-35, 37, 40-43,
45 covered by construction (verb wiring, single-writer prompt
constraints, crash-window resume via unmodified Phase 3 primitives).

* docs(#3676): regenerate skills/inventory/section-manifest/install-tree; baseline the intentional word-splitting pattern

npm run regen:derived output for the new command/workflow/reference
(epic #3344, ADR-1239 "Quick-batch binding"):
- skills/gsd-quick-batch/SKILL.md (generated from commands/gsd/quick-batch.md)
- docs/INVENTORY.md rows for /gsd-quick-batch, quick-batch.md,
  planner-quick-batch.md, and the quick-batch-dispatch.cjs/
  quick-batch-command-router.cjs CLI-module rows' now-live
  `/gsd-quick-batch` cross-reference (was "(separate, follow-up)")
  + docs/INVENTORY-MANIFEST.json (`node scripts/gen-inventory-manifest.cjs --write`)
- gsd-core/workflows/section-manifest.json (`npm run gen:section-manifest`)
  — research-phase/verification-wave gsd:section entries for the new
  quick-batch workflow
- tests/fixtures/install-tree/*.json (`npm run gen:install-tree`) —
  the new command/workflow/skill/reference files now ship to every
  runtime

scripts/lint-workflow-shellcheck-baseline.json: 3 new entries for
gsd-core/workflows/quick-batch.md's intentional flag-token/$ARGUMENTS
word-splitting (SC2046/SC2086) — the same deliberate unquoted-optional-
flag pattern gsd-core/workflows/quick.md already carries baselined
(e.g. `$DISCUSS_PARAM $RESEARCH_PARAM` in quick.md's own Step 2);
quoting would break the intended "omit this arg when the flag is
false" splitting.

* fix(#3676): close prompt-injection and argv/glob-injection gaps in quick-batch leaf dispatch

Security review pass findings, both confirmed real:

1. HIGH — prompt injection, no boundaries. Every leaf-dispatch fragment
   interpolated the raw, attacker-influenced task ${description} (and
   the shared ${TASK_CATALOG_TABLE}, broadcasting every item's raw
   description into every planner's prompt in the layer) straight into
   Agent() prompt bodies with no boundary. Fixed by wrapping every such
   interpolation in a <security_context> + DATA_START/DATA_END
   boundary, matching the CONCRETE convention already implemented in
   this repo (agents/gsd-debug-session-manager.md, agents/gsd-debugger.md,
   gsd-core/workflows/debug.md) — commands/gsd/quick.md's own
   <security_notes> only asserts this convention in prose, so the
   debug-agent files are the real precedent followed here. Added a new
   <security_notes> block to commands/gsd/quick-batch.md (it had none)
   documenting both this fix and the one below.

2. MEDIUM — unquoted $ARGUMENTS -> argv/glob injection.
   gsd-core/workflows/quick-batch.md and commands/gsd/quick-batch.md both
   ran `gsd_run quick-batch parse-args --raw -- $ARGUMENTS` UNQUOTED,
   causing shell word-splitting and pathname expansion on raw task-list
   text before the parser ever saw it. Fixed at the source: added a
   `--text <string>` form to the `parse-args` verb
   (src/quick-batch-command-router.cts) that accepts the ENTIRE
   $ARGUMENTS as ONE quoted argv element and does the whitespace split
   itself, in Node — which is never glob-aware, unlike the shell.
   Both call sites now use `--text "$ARGUMENTS"`. The `-- <tokens>` form
   is kept for direct/test callers that already have a real argv array.

The SC2086 baseline entry added for the original unquoted line is now
stale (`node scripts/lint-workflow-shellcheck.cjs` no longer reports
it) and has been removed; the two SC2046 entries for the UNRELATED,
still-unquoted `$([ "$VALIDATE_MODE" = true ] && echo --validate)`-style
conditional-flag splitting remain — that line only ever expands to one
of a few known-safe literal strings (never raw user text), matching
quick.md's own already-baselined convention exactly.

Tests: quick-batch-command-router.test.cjs covers the new --text form
(token splitting, glob-shaped text passing through literally
unexpanded, whitespace-only input). gsd-quick-batch-workflow.test.cjs
asserts the DATA_START/DATA_END boundary on every leaf prompt
(research-phase/planner-wave/plan-checker-loop/verification-wave,
including the shared task catalog) and the quoted --text call sites.

* fix(#3676): strengthen test-depth gaps in rows 9, 18, 24, 34, 35

Spec review pass findings — the test matrix claimed "yes" coverage
these assertions did not actually support:

- Row 9 (--jobs 0/-1/abc hostile case): previously asserted rejection
  only. Added an end-to-end assertion (tests/quick-batch-command-router.test.cjs,
  committed alongside the security fix that touches the same file) that
  .planning/quick-batches/ is never created for any rejected value —
  createBatch is genuinely never reached.
- Row 18 (--resume <unknown-batch-id>): previously only exercised a
  hand-corrupted BATCH.json, never a genuinely nonexistent batch
  directory. Added the real nonexistent-id case (also in
  quick-batch-command-router.test.cjs).
- Row 24 (post-planning updateBatchItems racing a concurrent
  completeQuickItem for a different item, both through
  withPlanningLock): zero test existed. Added a property test
  (tests/quick-batch.property.test.cjs, appended — Phase 3's own file,
  no existing test touched) exercising both call orders and asserting
  no lost update in the final on-disk manifest — the same technique
  Phase 3's own row-15 lock-contention property test uses (sequential
  calls through the real lock; a working mutex makes any interleaving
  equivalent to some serial order, so this is the same claim a literal
  concurrent-thread test would make without OS-level threading).
- Row 34 (worktree preserved on merge_failed) and row 35 (undeclared-
  deletion detection): both were previously asserted only at the pure
  routeMergeOutcome level. Added tests/gsd-quick-batch-merge-integration.test.cjs
  using the SAME real-git-fixture pattern tests/worktree-safety.test.cjs
  already establishes for executeWorktreeWaveCleanupPlan (real repo,
  real worktree, a REAL merge conflict / a REAL file deletion diffed
  against declared_deletions) — asserting the actual worktree directory
  survives on disk, not just that a pure function returns a
  preserveWorktree:true field. Named gsd-quick-batch-* so lint-test-
  file-count's bucketing doesn't fold it into any capped module bucket.

Row 48 (/gsd:quick regression) intentionally left as-is per the
reviewer's own framing: the byte-identity claim is already
mechanically proven by the changed-path diff (git diff --name-only
empty on those two paths IS byte-identity), and a genuine execution-
level regression test would require actually running the workflow —
out of scope for this repo's unit-test model (no other quick.md
regression test in this repo does that either).

* docs(#3676): add the changeset and user-facing docs the command needed

Standards review pass findings — both HARD:

- Missing changeset. None of the 6 prior #3676 commits touched
  .changeset/*. /gsd-quick-batch is a new user-facing command;
  CLAUDE.md/CONTRIBUTING.md require one. Added
  .changeset/silly-rams-caper.md (type: Added, pr: 0 placeholder —
  backfilled after the PR opens, matching CLAUDE.md's own documented
  convention and Phase 3's own precedent, #4190's
  .changeset/mellow-yaks-squeak.md). Uses the docs-convention hyphen
  form `/gsd-quick-batch` throughout, never the source-artifact colon
  form (`scripts/lint-docs-command-form.cjs` confirms 0 violations;
  that check scans docs/**, not .changeset/, so it was never actually
  in scope for the fragment itself, but the wording still follows the
  doc convention for consistency, matching how Phase 3's own fragment
  named the not-yet-shipped command).
- Missing docs. Added docs/how-to/batch-quick-tasks.md (Diátaxis
  how-to, matching docs/how-to/handle-quick-and-fast-tasks.md's
  existing convention for /gsd-quick /gsd-fast) covering --jobs,
  --validate, --research, --resume, --file, the capacity/isolation
  interaction, and resume/failure recovery. Cross-linked from
  docs/README.md's how-to index and from handle-quick-and-fast-tasks.md's
  own "Related" section. Added a /gsd-quick-batch section to
  docs/COMMANDS.md (same table format as the existing /gsd-quick
  entry) and docs/features/quick-batch.md (REQ-QB-01..12, same
  frontmatter shape as docs/features/quick-mode.md) — regenerated
  docs/FEATURES.md (179 features) and skills/gsd-quick-batch/SKILL.md
  via the standard generators.

* fix(#3676): close docs-parity, attribution, and generated-registry gaps gsd-test caught

gsd-test's real run against 155e8975b3 found 43 failures, all rooted in
this phase's own new command/workflow never being registered across
~10 independent generated/hand-maintained registries this repo keeps
in parity by convention. Root-caused each, no test weakened or
special-cased.

- help.md ↔ commands/gsd/ bidirectional parity (docs-parity-live-
  registry.test.cjs): added a /gsd:quick-batch entry to
  gsd-core/workflows/help/modes/full.md (the real help.md content;
  gsd-core/workflows/help.md is a thin dispatcher) documenting every
  flag (--file/--jobs/--validate/--research/--resume), matching the
  existing /gsd:quick entry's format.

- gen-section-manifest.test.cjs: quick-batch.md's
  `gsd_run query init.quick-batch` invocation used inline
  `$([ ... ] && echo --flag)` substitutions, which never satisfy the
  test's exact-whitespace-token / assigned-variable detection (the
  trailing `))` glued onto `--research` in the compound substitution
  broke the "exact token" match). Rewrote to the same
  VALIDATE_PARAM/RESEARCH_PARAM two-line pattern
  gsd-core/workflows/quick.md's own Step 2 already uses.

- runtime-launcher-parity.test.cjs: the 8 quick-batch/steps/*.md
  fragments that call gsd_run each needed their OWN embedded copy of
  the canonical shim preamble (every workflow .md that calls gsd_run
  carries its own copy — reading one file does not persist shell state
  into another). Ran `node scripts/sync-runtime-launcher.cjs`, which
  inserted it before each file's first gsd_run call.
  plan-checker-loop.md correctly has none — it never calls gsd_run
  directly.

- Namespace routing (skill-manifest.test.cjs, install-nested-
  layout.test.cjs, runtime-artifact-layout-surface.test.cjs): added
  `quick-batch` to commands/gsd/ns-workflow.md's `requires:` array and
  routing table (same namespace `quick` already routes through), and
  to src/clusters.cts's `utility` cluster (same cluster `quick`
  already belongs to). Verified by hand-running installRuntimeArtifacts
  + applySurface for augment/cline against a real temp install: exactly
  6 top-level gsd-ns-* router dirs, gsd-quick-batch correctly nested
  under gsd-ns-workflow/skills/, never re-flattened.

- mcp-server-catalog.test.cjs: hardcoded command count 71 -> 72 (a
  brand-new command is a real count change, not a bug this test should
  hide).

- model-omit-when-inherit-guard.test.cjs: added the canonical
  `<!-- #2517 model-omit-on-inherit -->` marker block to
  gsd-core/workflows/quick-batch.md (every leaf dispatch — planner/
  researcher/checker/executor/verifier — lives in a steps/ fragment,
  read combined with the host by this test's own readWorkflowCombined,
  same as quick.md's own research-phase.md carries it for its gated
  section). Also fixed a genuine pre-existing inconsistency in the
  test's own "#2711: the guarded set is derived from dispatch sites"
  check: its `nonDispatching` computation read the BARE host file while
  `derived` (the set it's checked against) reads the combined
  host+steps content — inconsistent with that same test file's own
  #2994 doc comment explaining why the combined read is necessary.
  quick-batch.md is the first workflow whose EVERY model="{...}"
  dispatch site lives in a mandatory (never gated) steps/ fragment —
  extracted to stay under ADR-1610's tighter NEW_FILE_CAP for a
  brand-new file — which is what exposed the mismatch. Fixed by using
  the same readWorkflowCombined read in both places.

- skill-frontmatter-contract.test.cjs: shortened
  commands/gsd/quick-batch.md's frontmatter `description` from 107 to
  91 chars (<=100 budget), and added `quick-batch.md` to the hand-
  maintained KNOWN_SKILLS consolidation allowlist with a #3676
  justification comment (a genuinely new first-party command, not a
  consolidation of an existing skill).

- workflow-fragments-emission.install.test.cjs: added `quick-batch.md`
  to the hand-maintained MARKED_WORKFLOWS set (composeWorkflow is
  deliberately NOT a no-op for it — its research-phase/verification-
  wave sections are gated).

- Regenerated all downstream artifacts (npm run build:lib && npm run
  regen:derived && npm run gen:plugin-skills -- --write && npm run
  gen:features -- --write): skills/gsd-quick-batch/SKILL.md,
  skills/gsd-ns-workflow/SKILL.md, install-tree fixtures for
  augment/cline/hermes/qwen/trae/zcode.

- emitted-attribution.test.cjs: agents/gsd-planner.md's #3676 addition
  (one new `load_mode_context` bullet pointing at the new
  gsd-core/references/planner-quick-batch.md reference) grew the file
  124 bytes without an acknowledgment trailer. Acknowledged below —
  the growth is the deliberate, additive, single-bullet change from
  the earlier feat(#3676) commit, not drift.

Verified: npm run build:lib clean, npx tsc -p tsconfig.build.json
--noEmit clean, GITHUB_BASE_REF=next npm run lint:ci fully green
(includes lint-workflow-shellcheck, lint-test-file-count,
lint-docs-command-form). The deep install/spawn/registry tests gsd-test
actually runs (docs-parity-live-registry, gen-section-manifest,
runtime-launcher-parity, install-nested-layout,
runtime-artifact-layout-surface, skill-manifest, skill-frontmatter-
contract, mcp-server-catalog, model-omit-when-inherit-guard,
workflow-fragments-emission) are not part of lint:ci — each fix above
was independently verified by hand-invoking the exact production
function the failing test calls (installRuntimeArtifacts, applySurface,
composeWorkflow, the CLUSTERS union, the section-manifest forwarding
regex) against the real repo tree and confirming the expected shape.

Emitted-Drift-Ack-Growth: gsd-planner.md — additive #3676 quick-batch mode bullet in load_mode_context (one new line pointing at gsd-core/references/planner-quick-batch.md); not drift.

* fix(#3676): trim the /gsd:quick-batch help.md entry to fit the LARGE tier line budget

skill-frontmatter-contract.test.cjs's "feature #3039: tiered help —
size budgets" enforces a SEPARATE line-count ceiling for
gsd-core/workflows/help/modes/full.md (FULL_BUDGET = 844 lines,
tighten-only ratchet, scripts/lib/allowlist-ratchet.cjs's
assertTightCeiling) — independent of the skill-frontmatter description-
length budget and consolidation allowlist I touched in the prior round;
those are unrelated checks in the same test FILE, not the same check.

Root cause: the /gsd:quick-batch entry I added to full.md in the
docs-parity fix round was 17 lines, pushing the file from 834 to 851
lines — 7 over the 844 ceiling. Condensed the entry (merged the
per-flag bullet list into one dense "Flags:" line, dropped from 3
Usage examples to 1) to 844 lines exactly — at the ceiling with zero
slack, which assertTightCeiling accepts (it only fails on
actualMax > ceiling, or on slack > grace when the ceiling is too
LOOSE — zero slack triggers neither).

Verified after trimming: full.md still contains a live /gsd:quick-batch
reference (bidirectional parity) and all 5 argument-hint flags
(--jobs/--validate/--research/--resume/--file) still appear as literal
tokens (docs-parity-live-registry.test.cjs's own flag-coverage check,
re-run by hand against the trimmed content).

Verified: npm run build:lib clean, npx tsc -p tsconfig.build.json
--noEmit clean, GITHUB_BASE_REF=next npm run lint:ci fully green.

* docs(#3676): backfill changeset pr number to 4212

Follow-up to fix(#3676) commits — .changeset/silly-rams-caper.md's
pr:0 placeholder backfilled with the real PR number now that
gh api POST /pulls has returned it (#4212). Matches CLAUDE.md's PR
Number Handling convention and Phase 3's own #4190 precedent
(708c5a3f8c). Doc-only (root-level .changeset/*.md fragment), exempt
from a fresh gsd-test run per pre-pr-gate.sh's DOC_ONLY_RE.

* fix(#3676): resolve prompt-injection-scan false positive on test fixture

tests/quick-batch.test.cjs:232's row 11b regression proves the task-list
parser carries a prompt-injection-shaped task description through
createBatch as inert data, never interpreted. The fixture has to be a
real "ignore all previous instructions..." phrase or the test asserts
nothing, but the full-file --diff scan flagged it once unrelated edits
in the same file pulled it into the changed-file set.

Add the file to prompt-injection-scan.sh's ALLOWLIST, matching the
sanctioned, precedented exemption already used for other legitimate
security-regression fixtures (tests/windsurf-conversion.test.cjs,
tests/health-validation.test.cjs, tests/continuation-grammar-parity.test.cjs)
per DEFECT.PROMPT-INJECTION-SCAN-COLLISION.

91ed46882a feat(#3675): quick-batch core primitives and resumable manifest (#4190)
* test(#3675): add failing tests for quick-batch core primitives

Adds the full behavioral (tests/quick-batch.test.cjs) and property-based
(tests/quick-batch.property.test.cjs) coverage for #3675's quick-batch core
primitives per the phase's 35-row test matrix — task-list parsing (inline +
--file, with path-confinement/symlink-escape/non-regular-file rejection),
collision-safe quick-id preallocation under withPlanningLock, BATCH.json
schema/validation/resume, dependency-DAG + partitionByFileOverlap wave
construction, and exactly-once STATE.md completion (including the
STATE-row-written-but-manifest-not-yet-updated crash window).

The import target (gsd-core/bin/lib/quick-batch.cjs, compiled from a
not-yet-written src/quick-batch.cts) does not exist yet — every test in both
files fails at the top-level require() before any assertion runs. Five
fast-check properties cover collision-freedom under lock contention, resume
idempotency, exactly-once STATE completion, wave totality, and DAG-respecting
wave order, per the design doc's property-based-coverage requirement.

* feat(#3675): implement quick-batch core primitives

Adds src/quick-batch.cts (ADR-457 build-at-publish, compiled to
gsd-core/bin/lib/quick-batch.cjs) implementing #3675's quick-batch core
primitives per the phase design lock — pure/state primitives and
CLI-testable core operations only, no agent dispatch, no worktree creation,
no user-facing command (Phase 4/#3676's job):

- parseTaskList / parseTaskListFromFile: inline bulleted/numbered task-list
  parsing (>=2 items required) and a --file variant strictly confined to the
  planning workspace root via requireSafePath, rejecting non-regular-file
  targets.
- allocateQuickIds / createBatch: collision-safe YYMMDD-xxx quick-id
  preallocation under withPlanningLock, checked against both on-disk
  .planning/quick/ entries and sibling .planning/quick-batches/*/BATCH.json
  manifests (never on-disk-only, which would miss another in-flight batch
  that hasn't dispatched any real quick directory yet) — replicates
  cmdInitQuick's own grammar rather than delegating to it (that function's
  2-second granularity is not batch-safe).
- computeWaves: deterministic wave construction combining dependency-DAG
  layering with partitionByFileOverlap (#3674), called per DAG layer over
  path-separator-normalized planned_files — normalization happens at this
  module's boundary, never inside the Phase 2 helper.
- loadBatch: fail-closed BATCH.json schema validation (corrupt/truncated
  JSON, wrong types, missing fields, out-of-batch dependency references,
  dependency cycles, a worktree path absent from disk).
- resumeBatch: skips complete items, never auto-retries failed items,
  propagates/reverses blocked status along the DAG to a fixed point, and
  detects a STATE.md row that already exists for a non-complete item (the
  "STATE written, BATCH.json not yet updated" crash window) — completing it
  without re-appending. Idempotent across repeated calls.
- completeQuickItem / hasQuickTaskRow: exactly-once STATE.md completion —
  appendQuickTaskRow (unmodified) is called at most once per quick id, gated
  by hasQuickTaskRow's own idempotency check re-parsing the real "Quick Tasks
  Completed" table, since appendQuickTaskRow itself carries no idempotency.

BATCH.json lives at .planning/quick-batches/<batch-id>/BATCH.json, a sibling
of .planning/quick/ — never inside it, so scanQuickTasks never misreads a
batch manifest as a broken quick task.

* docs(#3675): register the new quick-batch module

New src/*.cts -> bin/lib/*.cjs modules need four hand-maintained
registrations beyond the code itself: .gitignore (compiled artifact),
eslint.config.mjs (ADR-457: lint the .cts, not the emitted .cjs),
docs/INVENTORY.md's CLI Modules roster row plus the regenerated
docs/INVENTORY-MANIFEST.json cli_modules entry, and a CONTEXT.md glossary
entry matching the convention set by the sibling File Overlap Partitioner
Module (#3674) entry it sits beside.

NOTE: docs/INVENTORY-MANIFEST.json was updated BY HAND (alphabetically
sorted single-entry insertion into families.cli_modules, matching the
existing file's structure) rather than via
`node scripts/gen-inventory-manifest.cjs --write` — this session's
MEMTRACE-FIRST guard hard-blocks direct execution of that indexed script
path from Bash, with no available Memtrace tool to route through instead.
The orchestrator should re-run `node scripts/gen-inventory-manifest.cjs
--check` to confirm this hand-edit is byte-identical to the generator's own
output before merging.

* fix(#3675): resolve lint findings in quick-batch primitives and tests

Unsafe `any[]` assignment from `new Array(n)` in the DAG cycle-check color
array, two unnecessary `as string[]` casts TS 5.5's inferred type
predicates already narrowed, raw `fs.rmSync` in test cleanup (needs the
Windows-EBUSY retry budget `helpers.cleanup` carries), an unused `loadBatch`
import, an unbounded `mkfifo` subprocess spawn missing a timeout, and a
CONTEXT.md glossary illustration that looked like a real file reference.

* feat(#3675): close acceptance-criteria gaps found in review

Standards- and spec-axis review (plus a self-caught race) surfaced real
gaps against issue #3675's own acceptance criteria and this repo's test
conventions:

- BATCH.json was missing options, base_revision, per-item wave, and
  per-item commit — the issue's AC explicitly lists all four as things
  the manifest must track. Added them: createBatch persists caller-supplied
  batchOptions/baseRevision verbatim and assigns each item its computed
  wave index; completeQuickItem now persists the commit onto the item,
  not just the STATE.md row. All four are backward-tolerant on load (an
  older/hand-built manifest without them still validates).
- resumeBatch had no "incompatible base divergence" check at all, despite
  the AC and the ADR's own "Base divergence" section requiring one. Added
  an opt-in currentBaseRevision comparison that fails closed with a
  recoverable diagnostic on mismatch, and touches nothing on refusal.
- resumeBatch read-modify-wrote BATCH.json OUTSIDE withPlanningLock — the
  only durable write path in this module that wasn't lock-protected,
  a real lost-update race against a concurrent completeQuickItem or
  another resume. Now runs inside the same lock createBatch/
  completeQuickItem use.
- loadBatch and collectExistingBatchQuickIds used raw JSON.parse with no
  size cap (security review, Low/informational); switched to the
  existing safeJsonParse (1MB cap) for defense-in-depth.
- Parser (parseTaskList) had only example-based tests; CLAUDE.md requires
  a fast-check property test for parsers. Added one plus a companion
  reject-property for <2 items.
- The id-exhaustion fail-closed ceiling (MAX_TIME_BLOCK) was untested at
  any boundary. Exported the pure allocateIdsGivenUsed/MAX_TIME_BLOCK for
  direct limit-1/limit/limit+1 testing without needing 46k fixture dirs.
- Issue AC explicitly asks for prompt-injection-payload test coverage,
  distinct from the existing shell-metacharacter test; added one.
- Test row 9 (FIFO skip) silently returned instead of calling t.skip(),
  so an unsupported platform would report a pass rather than a documented
  skip; fixed to bind the test-context param and skip properly.
- Extracted toWaveInput to remove a 2-site production duplication of the
  QuickBatchItem -> computeWaves reshape (Standards-axis smell).
- Added the required .changeset/ fragment (CONTRIBUTING.md: editing src/
  is user-facing even though the compiled .cjs is gitignored).

* fix(#3675): restore "not valid JSON" wording in loadBatch's parse-failure reason

gsd-test caught this: switching loadBatch to safeJsonParse changed the parse-
failure message shape ("... parse error — ...") without preserving the
"not valid JSON" substring row 27's own test asserts on. Re-wrap
safeJsonParse's error into the original diagnostic phrasing regardless of
which of its three failure modes fired.

* docs(#3675): backfill changeset pr number to 4190

* fix(#3675): detect a silently-no-op mkfifo on Windows, not just a throwing one

CI caught this on windows-latest: row 9's platform-skip only caught mkfifo
throwing (command not found). On this runner mkfifo resolves to something
that exits 0 without creating a file (NTFS has no FIFO concept), so
execution fell through to parseTaskListFromFile against a path that
doesn't exist, producing an ENOENT stat error instead of the expected
"not a regular file" rejection. Check the artifact actually exists before
trusting a zero exit code, and skip with a documented reason either way.

acb903c2e8 enhance(#3661): make the code-review hook point configurable (#4159)
* feat(#3661): make the code-review hook point configurable

Add `workflow.code_review_point` (`execute:post` default, or
`execute:wave:post`) so a multi-wave phase can run code review once per
wave instead of once at the end, scoped to what changed since the phase's
prior review.

The code-review capability now declares its step at both loop points via a
new generic `pointFrom` step field: `pointFrom` names an enum config key,
and the step is only active at its own `point` when that key resolves to
a matching value. `_resolvePointGate` (capability-activation.cts) is the
single shared implementation consumed identically by loop-resolver.cts and
capability-state.cts, and capability-validator.cjs enforces that `pointFrom`
references an enum key whose values cover the declaring step's own point.

code-review.md's manual-invocation gate now reads `workflow.code_review`
directly instead of probing registry presence at the hardcoded execute:post
point (so manual `/gsd-code-review` keeps working regardless of which
automatic point is configured), and its file-scope tiers narrow to what
changed since the phase's last review commit when one exists.

execute-phase.md's wave-post step dispatch gets a small, precedented
carve-out so the code-review skill still receives its required phase
argument when dispatched generically (caught by the isolated spec review).

Closes #3661

Emitted-Drift-Ack-Growth: code-review.md — #3661 adds a point-aware config gate check and LAST_REVIEW_COMMIT-based incremental scoping to the file-scope tiers.
Emitted-Drift-Ack-Growth: execute-phase.md — #3661 adds one carve-out sentence so the wave-post generic step dispatch passes PHASE_NUMBER to the code-review skill.

* docs: backfill changeset PR number for #3661 (#4159)

* fix: scope tests/io.test.cjs's fs.writeSync fault-injection mocks by fd

Five fault-injection mocks in the "bug #1008" describe blocks intercepted
every fs.writeSync call regardless of file descriptor, and several threw or
truncated unconditionally on the first call. This surfaced as an
intermittent macOS CI failure: node:test's own IPC channel back to the
parent process (which also goes through fs.writeSync internally) could get
a bogus injected error or truncated write if node's internal machinery
called it while one of these mocks was active, corrupting the message
frame the parent tried to deserialize ("Unable to deserialize cloned
data.", location tests/io.test.cjs:1:1, uncaughtException — a whole-file
IPC crash, not a test assertion failure).

Root cause confirmed by a working counter-example already in the same
file: the "#3912 A6" mocks gate on `fd !== 2` before any fault injection
and were never implicated. Applied the same fd-scoped pattern to the five
unscoped mocks (four output()-targeting tests gate on fd 1, one
error()-targeting test gates on fd 2), and added a regression test proving
an unrelated fd passes through untouched while the fault-injection mock is
active.

Found while verifying #3661; unrelated to that change's own diff.

b0572c0108 feat(#3674): extract shared file-overlap wave partitioner (#4166)
* test(#3674): characterize existing wave-dispatch output and add tests for the extracted partitioner

Pins resolveWaveDispatch's and emitWorkflowScript's current, unextracted
output (chain-overlap, disjoint-empty-set, and a multi-wave/multi-stage
golden script) as a regression safety net ahead of extracting
partitionStages into a standalone module. Also adds the new module's
unit and property tests (test matrix rows 1-11) against its expected
public API, which does not exist yet and is added in the next commit.

* feat(#3674): extract file-overlap partitioner into a shared, generic module

Moves partitionStages' greedy first-fit file-overlap algorithm into a new,
dependency-free src/file-overlap-partitioner.cts module (partitionByFileOverlap),
generalized over a plain {id, files}[] shape rather than claude-orchestration.cts's
Plan/Wave interfaces. partitionStages becomes a thin adapter mapping its own
Plan[] shape onto the generic input and back — behavior-preserving, no dependency
ordering, no path normalization, no filesystem access moved or added. Enables a
future consumer (quick-batch, #3675 / ADR-1239) to reuse the same primitive
without pulling in orchestration internals.

* docs(#3674): register the file-overlap-partitioner module bookkeeping

New src/*.cts -> bin/lib/*.cjs modules need four hand-maintained
registrations beyond the code itself: .gitignore (compiled artifact),
eslint.config.mjs (ADR-457: lint the .cts, not the emitted .cjs),
docs/INVENTORY.md's CLI Modules roster row (regenerated via
gen-inventory-manifest.cjs --write), and a CONTEXT.md glossary entry
matching the convention set by similarly-scoped leaf modules
(text-lines.cts, plan-dependency-graph.cts, spec-section.cts).

* fix(#3674): alphabetize INVENTORY.md row, manifest regen no-op, fast-check import already correct

- docs/INVENTORY.md: move file-overlap-partitioner.cjs row to alphabetical position
- docs/INVENTORY-MANIFEST.json: regenerated via gen-inventory-manifest.cjs --write,
  produced no diff (manifest is keyed by content, not row order)
- tests/claude-orchestration.test.cjs's direct require('fast-check') is correct as-is:
  tests/helpers/fast-check-setup.cjs's own docstring scopes the shared-seed wrapper to
  "every *.property.test.cjs file"; claude-orchestration.test.cjs is not a .property.test.cjs
  file, and every .property.test.cjs file sampled uses the wrapper consistently. No outlier.

* fix(#3674): constrain the no-overlap property test to unique ids, fixing an ambiguous duplicate-id reconstruction

The `no two plans in the same stage share a modified file` property
reconstructs which physical item produced each output id via
`remaining.findIndex(r => r.id === id)`. Under duplicate ids (an
explicitly-supported input shape for `partitionByFileOverlap`) that
reconstruction can pick the wrong physical occurrence, producing a
false-positive overlap failure (observed counterexample: p0(f1),
p208(f1), p208([]) — correctly staged as [[p0,p208#2],[p208#1]], but
misread by id-order as [[p0,p208#1],...], which do overlap).
Properties (a) determinism and (b) totality already exercise
duplicate ids correctly and are left unchanged; only this property's
generated items are now constrained to unique ids via
`fc.uniqueArray`, where the reconstruction is unambiguous.

bf4485ada2 enhance(#3717): make the edge probe's shape cues language-aware via an optional text_en field (#4156)
* test(#3717): add failing-first coverage for text_en language-aware classification

Adds unit tests for the not-yet-implemented text_en field on Requirement
(fallback selection, empty/whitespace/non-string rejection, shapes-override
precedence), a SHAPE_CUES/VALID_SHAPES parity guard (RULESET.GENERATIVE-FIX),
and workflow-prose contract tests asserting spec-phase.md Step 5.5 documents
populating text_en for response_language projects. All new tests are RED
until src/edge-probe.cts and the workflow docs are updated.

* feat(#3717): make edge-probe shape classification read an optional text_en field

Requirement gains an optional text_en; classifyShape's own signature stays
untouched (a locked, directly-tested export), and the text_en ?? text
selection is pushed to proposeEdges' single call site instead. text_en is
validated fail-closed: an empty or whitespace-only value throws rather than
silently winning the ?? fallback and degrading classification to zero shapes.

This makes the #2773 doc-only translation convention an explicit,
validatable field instead of an invisible instruction, per the approved
Form-1 scope on #3717.

* docs(#3717): document the text_en field across spec-phase, reference and how-to docs

Updates Step 5.5's response_language instructions, the edge-probe reference
Inputs contract, the FEATURES.md fragment, and the non-English how-to guide
to describe the new text_en field: text keeps the requirement's own wording
in all cases, text_en (when populated) is the engine-only English rendering
the classifier prefers.

* docs(#3717): record the text_en locked-surface change in CONTEXT.md and ADR-550

Updates the Edge Probe Module glossary entry to describe the text_en field
and its fail-closed validation, and appends an ADR-550 amendment recording
why this is additive and does not re-open the #652 LLM-classifier rejection
(text_en is a plain field read by the existing deterministic regex
classifier, not a new model-dependent surface).

* docs(#3717): add changeset fragment and regenerate FEATURES.md

pr:0 placeholder — backfilled with the real PR number after the PR opens.

* docs(#3717): attribute the text_en machine check to engine-level validation, not prose tests

Code-review (Spec axis) finding: the workflow-prose contract tests and the
ADR-550 amendment overclaimed themselves as "the machine check the #2773
doc-only stopgap lacked." That check is actually engine-level
(validateRequirement/classifyShape, covered in tests/edge-probe.test.cjs) —
the prose tests are the same style of assertion #2773 already used. Reworded
both to attribute the claim correctly.

* fix(#3717): rewrap spec-phase.md so the id-unchanged sentence stays on one line

The #3717 rewrite of Step 5.5's response_language paragraph moved a line
break so "requirement `id`s" ended one physical line and "are never
translated" started the next. The pre-existing #2773 regression test
(tests/edge-probe-spec-phase-contract.test.cjs) asserts id + "never
translated" on the SAME line (no \n in between, matching git's own
line-oriented prose), so the reflow silently broke it. Rewrapped so the
sentence lands on one line again, verified against every #2773/#3717
regex assertion in that test file.

Emitted-Drift-Ack-Growth: spec-phase.md — #3717 adds text_en documentation to Step 5.5 (response_language paragraph + REQS_JSON heredoc comment); this growth is this PR's own diff, not incidental drift.

7c116b1c17 fix(#3697): warn when the phase-complete Requirements-line tokenizer under-selects REQ-IDs (#3744)
* fix(#3697): warn when the Requirements line under-selects REQ-IDs

`cmdPhaseComplete` tokenizes ROADMAP's `**Requirements**:` line by splitting
on `[,\s]+` and keeping tokens matching the anchored REQ-ID shape. That is
correct for the canonical comma list the template ships, and silently wrong
for every other form:

  `RANGE-01 … RANGE-05`  ->  the two ENDPOINTS only; the interior IDs are
                             never considered, yet `requirements_updated`
                             reports true with zero warnings
  `RANGE-01…05`          ->  ZERO IDs; the whole line is inert

The silence is structural: the only cross-check, `ghostReqIds`, is itself
`citedReqIds.filter(...)`, so an ID the tokenizer dropped is invisible to it
by construction — and to `traceabilityWriteMisses` and `requirements_updated`
with it.

Warn on both paths. This does not add range support: the selected set is
unchanged, so no existing ledger write changes. The trigger is ID-SHAPED
EVIDENCE only — an ID-shaped substring the tokenizer did not select, or a
range operator joining two IDs — with parenthetical citations and HTML
comments stripped before the scan, so the #2334/#2339 over-warning on
`None`, on the shipped `<!-- brackets optional -->` template comment, and on
annotated lines cannot return.

Regression tests extend the #2316/#2334 fixture family in tests/phase.test.cjs
(10 cases: 4 defect, 2 canonical controls, 4 negative-space controls).

Fixes #3697

* fix(#3697): rework under-selection detection onto tokens, not a free-text scan

Round 2, driven by the P4.6 cross-AI review (codex, gpt-5.6-sol) of b3ce71cb.
That review refuted 5 of 9 claims; three were false-positive classes in exactly
the category #2334/#2339 had to REMOVE:

  `RANGE-01, RANGE-02 - 3 points`        the bare-hyphen alternative read
                                         `RANGE-02 - 3` as a range
  `REQ-01, REQ-02 — locked per ADR-7.`   the trailing period kept `ADR-7.` out
                                         of the anchored filter, so the
                                         unanchored substring scan reported it
                                         as unparsed
  `REQ-01, REQ-02 (see (ADR-7), then ADR-8)`
                                         nested parens left `ADR-8)` behind

Replaces the free-text substring scan + loose range regex with three narrow,
token-based rules (R1 range-shaped token, R2 pure range operator flanked by two
selected IDs, R3 zero-selection with ID-shaped text). Also fixes the review's
CLAIM 9: the warning said IDs were "marked complete" when a ghost range marks
nothing — it now says "selected".

Side effect: the two false NEGATIVES the same review found are now covered —
`RANGE-01 through RANGE-05` and a parenthesised `(plus RANGE-02..RANGE-05)`.

NOT YET DONE (see the handoff prompt): regression tests for the four false
positives, the two new true positives, and the #3697-4 tightening the review's
CLAIM 8 asked for (it currently filters on the warning's phrasing rather than
asserting silence). Verified so far: tsc clean, the 10 existing #3697 tests
green, and a 20-case standalone harness covering every case above.

* test(#3697): pin the v2 token-detector boundary end-to-end

Six new cases + two hardenings for the review findings against v1:

- #3697-1 gains the worded spaced range (`RANGE-01 through RANGE-05`) —
  the operator set's `to|thru|through` arm was previously untested.
- #3697-5 (new): a tight range hidden inside balanced parentheses
  (`RANGE-01 (plus RANGE-02..RANGE-05)`) warns, names the range token,
  and ticks exactly RANGE-01 — the paren shave must not hide it.
- #3697-4 gains the four false-positive classes a free-text detector
  produced: numeric estimate (`- 3 points`), date annotation, em-dash
  citation with trailing period (`— locked per ADR-7.`), and nested
  parenthetical citations.
- #3697-3 and #3697-4 now assert the ENTIRE warnings channel is empty,
  not that one phrase is absent — a re-worded over-warning cannot pass.

Negative control: against the merge-base with its lib rebuilt, all 6
defect tests fail and all 10 controls pass.

* fix(#3697): close round-2 review findings — annotation false positives

Round 2 of the adversarial review (against 822a72a04) refuted five
claims; this closes the false-positive class and the cheap misses:

- R1's bare-hyphen arm now demands a full ID on BOTH sides
  (`REQ-01-REQ-05`): `LETTERS-\d+-\d+` is also a date-like annotation
  (`FY-2026-08`) and a sub-numbered ID, and warning on those is the
  expensive class. Tight hyphen shorthand with a live selection is the
  disclosed false negative; at zero selection R3 still catches it.
- R2 requires the endpoint pair to imply an INTERIOR (same prefix,
  gap > 1): `REQ-02 - REQ-03` selects both endpoints and can drop
  nothing, so an annotation hyphen between adjacent IDs stays silent.
- R3 skips placeholder-led lines: `None (per ADR-7)` is a declared-empty
  line citing its rationale, not unparsed residue.
- Token shave: quotes/backticks now shaved from alphanumeric tokens
  (`` `RANGE-02..RANGE-05` `` warns); punctuation-only tokens get a
  bracket-only shave so `(..)` surfaces its operator.
- 256-char token cap bounds the quadratic unanchored substring test.
- Warning text mentions range expansion only when a range rule fired.

Tests: 6 new cases (22 total). Negative control against the merge-base:
8 defect tests fail, 14 controls pass.

* fix(#3697): close round-3 review findings — half-spaced ranges, cross-prefix annotations, markdown wrappers

Round 3 of the adversarial review (against 2eb92dd0e) refuted four
claims; this closes them:

- Half-spaced ranges (`REQ-01 -REQ-05`, `REQ-01- REQ-05`) split at the
  tokenizer before R1's `\s*` can see them and under-selected silently.
  A glued-fragment rule warns when an operator is glued to a full ID
  with an ID-shaped neighbour on the open side and the endpoint pair
  implies an interior.
- Cross-prefix pairs around a separator no longer read as ranges:
  `REQ-02 - (ADR-7)` and `REQ-02 (...) (ADR-7)` are annotations, and
  real ranges are same-prefix by nature. `impliesInterior` now returns
  false on prefix mismatch and computes the gap with BigInt (parseInt
  lost precision past 2^53).
- The token shave now removes markdown emphasis markers and curly
  quotes, so `**None** (per ADR-7)` reaches the placeholder gate and
  `**RANGE-02..RANGE-05**` reaches R1.
- The unanchored-substring cap rises to 2048 (a markdown-link range
  with a long URL cleared 256); the anchored range regexes scan
  linearly and drop their cap.

Tests: 6 new cases (28 total; 377/377 file-wide). Negative control
against the merge-base: 11 defect tests fail, 17 controls pass.

* fix(#3697): round-4 review finding — word operators excluded from glued-fragment rule

`TOREQ-05` is a valid prefix-agnostic REQ-ID, and the glued-fragment
rule read it as `to` + `REQ-05`, warning on the canonical two-ID list
`REQ-01, TOREQ-05`. Glued fragments are now SYMBOL-operator-only
(`..`+, ellipsis, dashes): a word operator glued to an ID is an ID,
not a range spelling.

Tests: word-operator-prefixed ID control (misparse channel silent; the
fixture's ghost-ID warning legitimately fires, so the whole-channel
assertion stays with the registered controls) and an underscore-wrapped
tight-range defect case. 30 targeted cases; 379/379 file-wide; negative
control: 12 defect tests fail on the merge-base, 18 controls pass.

* fix(#3697): round-5 review findings — trailing word-op glue, dot shave, honest wording

- The glued-fragment TRAILING arm takes the word operators back: an ID
  must end in digits, so `REQ-01through` can never be an ID — the
  round-4 TOREQ collision was leading-arm-only, and symbol-only on both
  arms lost the `REQ-01through REQ-05` typo class.
- A trailing run of 2+ dots survives the punctuation shave: `REQ-01..`
  is a glued range operator, not sentence punctuation, and the shave
  was silently eating the `REQ-01.. REQ-05` form.
- The warning now says the line "could not be parsed as" a
  comma-separated REQ-ID list: `**REQ-01**, **REQ-05**` IS such a list
  — the selector just cannot parse decorated tokens — and a warning
  that misstates the input teaches readers to distrust it.

Tests: two new trailing-glue defect cases (32 targeted; 381/381
file-wide). Negative control: 14 defect tests fail on the merge-base,
18 controls pass.

* test(#3697): use t.after for cleanup per CONTRIBUTING test ruleset

CONTRIBUTING bans try/finally inside test bodies (it masks failures);
the approved shape is `t.after(() => cleanup(tmpDir))`. All seven
converted tests are this PR's own additions; the file's pre-existing
instances are untouched.

* chore(#3697): add changeset fragment for the Requirements-line under-selection warning

changeset-lint fails on this PR (fail_missing_fragment): src/phase.cts is a
user-facing surface and the branch carried no .changeset/*.md. Adds the Fixed
fragment via `npm run changeset -- --type Fixed --pr 3744`, symptom-led per
the house format, with the (#3697) backlink.

* refactor(#3697): extract the Requirements-line detector to a testable surface

Round-3 review Blocker 1 requires a fast-check property test over this
detector (`RULESET.TESTS.property-based-testing`: modules implementing
parsing contracts must include at least one), and Blocker 2 requires
limit-1/limit/limit+1 fixtures on its 2048-char token cap
(`RULESET.TESTS.boundary-coverage.fixtures`). Neither is expressible while
the logic is a closure inside `cmdPhaseComplete`: every existing #3697 test
reaches it by spawning the CLI, and a property test cannot pay a subprocess
per generated case.

So the selector and the three detection rules move to module scope as
`analyzeRequirementsLine` (pure, exported) plus
`formatRequirementsLineWarning`, and `cmdPhaseComplete` calls them. This
commit changes NO behaviour: `tests/phase.test.cjs` is untouched here, and
the pre-round suite passes against it unmodified (403/403).

Two things the move makes explicit rather than incidental. The selector and
the detector tokenize the SAME line DIFFERENTLY — the selector strips only
`[` and `]`, the detector also shaves quotes, emphasis and trailing sentence
punctuation — and that gap is deliberate: it is why `ADR-7)` is not selected
while `ADR-7` is still nameable in a warning. They now sit adjacent with the
reason written down, so they cannot drift apart silently.

And the stale citations in the moved comment are corrected. It pointed at
src/phase.cts:833,920,1078 for the `**Requirements**: TBD` seeds, which had
drifted to 1132/1237/1413, and at `templates/roadmap.md:32`, which is
`gsd-core/templates/roadmap.md:32`. Both are now anchored by content.

* fix(#3697): stop the warning claiming a misparse that did not happen

Round-3 review Major 3 and Minor 4. Both are the same defect: the warning
asserted more than the evidence supported.

MAJOR 3 — a correct comma list such as `RANGE-01, RANGE-02 — RANGE-05
deferred` warned "could not be parsed ... Range forms are not expanded;
rewrite the line". Reproduced: it selects RANGE-01, RANGE-02 AND RANGE-05,
i.e. every ID written on the line. Nothing was dropped, and the pinned
control only stayed silent because its pair was ADJACENT (gap == 1), so the
control was passing by accident of the fixture rather than by the rule.

The obvious fix — go silent — is not available. `RANGE-02 — RANGE-05` as a
range and as an annotation separator are textually identical, and no
token-level rule separates them; staying quiet re-opens the exact silent
under-selection #3697 is about. Deciding the ambiguity by assertion in
either direction is wrong. So it is DISCLOSED: the warning now has two
channels, chosen by whether any ID-shaped token was actually left unselected
(`droppedIdShaped`).

  * something was dropped (tight range, glued fragment, inert residue)
    -> "could not be parsed as a comma-separated REQ-ID list", as before.
  * nothing was dropped (only the spaced-operator rule fired)
    -> "contains what reads as a range between two cited REQ-IDs", stating
    both readings and saying explicitly that an annotation separator means
    the line is already correct.

This retires the "could not be parsed" wording for the four #3697-1 spaced
cases too, and that is a deliberate expectation change rather than a fix
counted twice: those lines never failed to parse either. They still warn,
still name the selected IDs, and still assert the endpoint-only marking is
unchanged; #3697-1 now also asserts the misparse channel stays SILENT.

MINOR 4 — `Deferred (see ADR-7)` reported `Unparsed text: ADR-7`, naming a
citation as requirement content it had failed to read. The trigger is
correct and stays: #3697's acceptance criterion asks for a warning "when it
selects zero IDs from a line that is non-empty and is not the `TBD`
placeholder", and inferring placeholder-ness from arbitrary prose is the
free-text heuristic this detector exists to avoid. What was wrong is the
wording, so the non-range arm now says "ID-shaped text that was not
selected" and names the escape the author actually has (`TBD` / `None`).

Tests: #3697-9 (three spaced forms — must warn, must NOT claim a misparse,
must offer both readings) and #3697-10 (`Deferred (see ADR-7)`, `N/A
(tracked in ADR-12)` — must warn, must not say "Unparsed text", must not
diagnose a range, must name the placeholder escape).

Reversion control: reverting the ambiguous channel fails #3697-9 (3 named
tests); reverting the R3 wording fails #3697-10 (2 named tests).

* fix(#3697): cap every token predicate, complete the dash set, cover the boundary

Round-3 review Blocker 2 and Nit 6, plus one self-found finding. All three
are about the detector's own predicates, so they land together.

BLOCKER 2 — the 2048-char budget had no boundary coverage.
`RULESET.TESTS.boundary-coverage.fixtures` requires limit-1 / limit /
limit+1 for any budget parameter. #3697-B1 and #3697-B2 now exercise 2047 /
2048 / 2049 against BOTH predicate families the cap guards, and each asserts
its fixture's exact length before asserting behaviour, so a mis-built
fixture fails loudly rather than passing at the wrong size. Clause (d) of
that rule — an input pushed within reserve-distance of the limit — has no
referent here: this is a hard cap with no reserve constant beside it, and
the test comment says so rather than leaving the omission to be re-derived.

NIT 6 — the cap guarded only the unanchored ID-substring regex. The
anchored range regexes were left uncapped, justified by a comment asserting
they scan linearly. The finding is right that this is informational (they
are anchored; the input is a local ROADMAP.md), but an asserted property is
cheaper to enforce than to defend, so all three predicates now share one
`short()` guard. #3697-B2 is what pins it: at 2049 the anchored scan must
now decline to classify.

SELF-FOUND (RV4 guard-shape census) — the range-operator set is a list this
code fixes at author time over a domain that grows without it, so the round
owes a census of what the enumeration reaches.

  reached:     `..`+, U+2026, U+2013, U+2014, ASCII `-`, to/thru/through
  NOT reached: U+2010 hyphen, U+2011 non-breaking hyphen, U+2012 figure
               dash, U+2015 horizontal bar, U+2212 minus sign
  consequence: a range spelled with any of those is SILENTLY under-selected
               — #3697's own defect, in the code that exists to fix it

Those five close. They are the same operator at a different codepoint and
carry none of the ASCII hyphen's collision risk, because they are not the
REQ-ID separator: `FY-2026-08` is date-shaped only with ASCII hyphens, so a
U+2010 never reaches the ID shape. They therefore join the NOHYPHEN arm
beside `—` and `–`; the strict full-ID-both-sides shape the bare hyphen is
held to is untouched, and #3697-12 pins that.

Still NOT reached, declined with reason rather than left unstated: `→`, `~`,
`..=`, `..<`, `until`, and `up to` (two tokens, so never one operator
token). Each is a symbol or word with an independent non-range use between
two REQ-IDs — the over-warning class #2334 cost three rounds.

Reversion control: reverting the uniform cap fails #3697-B2 (limit+1);
reverting the dash set fails #3697-11 (5 named tests).

* test(#3697): add the fast-check property coverage the parser rule requires

Round-3 review Blocker 1. `RULESET.TESTS.property-based-testing` (CONTEXT.md)
requires modules implementing parsing contracts to carry at least one
fast-check property test asserting a domain invariant, and the round-2 diff
had zero occurrences of `fc.` across its +311 test lines. Five properties,
1,900 generated cases:

  P1  soundness of silence (boundary containment) — for ANY canonical comma
      list of well-formed REQ-IDs, the selected set EQUALS the written set
      and nothing warns. This is the #2334 over-warning invariant and the
      #3697 under-warning invariant asserted as one statement, over
      generated IDs rather than hand-picked ones. It generalises #3697-4b:
      a prefix beginning with a word operator (`TORANGE-05`) is an ID, and
      P1 covers that class rather than the single example.
  P2  completeness — a same-prefix pair with an interior between them,
      separated by any of the nine spaced operators, ALWAYS warns.
  P3  the #2334 invariant — an ADJACENT pair around a separator can drop
      nothing, so it stays silent however it is annotated.
  P4  totality + idempotency — total over arbitrary strings, deterministic,
      and the formatter agrees with the analysis on whether there is
      anything to say (a warn with no text, or text with no warn, is a
      channel that can go silent or noisy on its own).
  P5  containment — every selected ID is ID-shaped and appears verbatim in
      the input.

Honest scoping, since a property test is easy to overclaim: P1, P3, P4 and
P5 hold against the round-2 code as well as this one — they are regression
guards, not bug-finders, and their value is that the invariants are now
stated and generatively checked rather than implied by examples. P2 is the
one that would have failed before the dash enumeration was completed.

fast-check v4 removed `fc.stringOf`, so the ID-prefix tail is built from
`fc.array(...).map(join)` with the alphabet pinned to the selector's own
`[A-Z0-9]` class.

These live in tests/phase.test.cjs rather than a new
`phase.property.test.cjs`: `lint-test-file-count` caps a production module
at 2 test files and phase.cts is already at its allowlisted entry, so a new
file would trade one gate for another.

* docs(#3697): document the ROADMAP Requirements-line grammar

Round-3 review Minor 5 — the change adds net-new user-visible warning output
for a grammar constraint documented nowhere under docs/. `type: Fixed` is
docs-exempt so this does not block, but a warning about a rule the reader
cannot look up is not actionable, and that is worth fixing whether or not a
gate demands it.

Added as a subsection of `phase complete` in docs/CLI-TOOLS.md, beside the
existing SUMMARY artifact-check advisory it is a sibling of: the supported
comma-list form, why ranges are deliberately not expanded, that `TBD` and
`None` are the entire placeholder vocabulary, and what each of the two
warning voices means — including that the range/annotation one may be
reporting a line that is already correct.

Existing file rather than a new one, deliberately: docs/ carries generated
indexes and zh-CN / ja-JP trees, and a new top-level page invites a parity
or index gate this change has no reason to touch.

* fix(#3697): rule-scope the warning-channel discriminator

Self-found at the round's pre-push review, against the Major 3 fix two
commits back. That fix chose the channel from a LINE-GLOBAL question — "was
any ID-shaped token left unselected?" — while the rules that produce the
warning are not line-global. The two disagree as soon as the line carries an
ID-shaped token no rule fired on:

  `RANGE-01, RANGE-02 — RANGE-05 deferred per (ADR-7)`

`(ADR-7)` survives the selector's bracket strip, so the global test called it
a drop and sent the line to the assertive channel — putting the false "could
not be parsed ... rewrite the line" claim back on a correct line. That is
review finding Major 3 returning through a side door, and it directly
contradicts #3697-4, which pins a parenthetical citation as NOT unparsed
residue.

The discriminator is now rule-scoped: R2 is the only ambiguous rule, so the
ambiguous channel requires that R2 fired, that no other rule did, and that
every endpoint R2 fired on was actually selected. The last conjunct is not
redundant — the detector shaves brackets and the selector does not, so R2 can
fire on a `(RANGE-02)` that was never selected, and that IS a drop:

  `RANGE-01 (RANGE-02) — RANGE-05`   -> assertive, correctly

`droppedIdShaped` is replaced by `spacedRangePairs` (R2's hits, so the
channel can ask about the endpoints the rule fired on) and the
`rangeReadingOnly` verdict.

Reversion control: against the line-global rule, #3697-9b fails. #3697-9c
passes under both rules — there the dropped token IS the R2 endpoint, so the
two agree; it is a regression guard, not a bug-finder, and is recorded as
such rather than counted as a second control.

* fix(#3697): hold every dash to the strict range shape, not just ASCII

Self-found at the round's pre-push review, and it CORRECTS a claim made two
commits back. That commit widened the range-operator set by five Unicode
dashes and asserted they "carry none of the ASCII hyphen's collision risk,
because they are not the REQ-ID separator". That reasoning was wrong. The
collision is a property of the SHAPE — `PREFIX-\d+ <dash> \d+` is also a date
(`FY-2026-08`) and a sub-numbered ID (`API-2-01`) — and the shape does not
care which dash sits in the operator slot, because the ID's own separator is
still ASCII either side of it. Measured:

  RANGE-01 (target FY-2026-08)   silent   <- pinned by #3697-4
  RANGE-01 (target FY-2026‐08)   WARNED   <- same line, U+2010

So the widening reintroduced the #2334 over-warning class on a date
annotation. It also exposed that the inconsistency PREDATES this PR: U+2013
and U+2014 were already in the loose arm at ce71dd399, so the en- and em-dash
forms of that same date annotation warned before round 3 ever ran.

One rule for every dash: a tight range spelled with any of the eight must
carry a FULL ID on both sides, exactly as the bare hyphen already had to.
`..`, `…` and the word operators stay loose — no date or sub-number reading
exists between two numbers, so the strict shape would cost them coverage for
nothing.

The cost is a false negative, and it is one the design already accepts:
`RANGE-01, RANGE-02-05` is silent today, deliberately, and now
`RANGE-01, RANGE-02–05` is too. That removes an inconsistency rather than
opening a gap, and a bare `RANGE-02–05` still warns — it selects nothing, so
R3 catches it.

Tests: #3697-13 (date annotation AND sub-numbered ID silent for all eight
dashes), #3697-13b (full-ID tight range still warns for all eight),
#3697-13c (loose operators keep their numeric endpoint), #3697-13d (the
accepted false negative is symmetric, and the bare zero-selection line still
warns).

* fix(#3697): close the round's own pre-push review findings

An adversarial cross-AI review of this round refuted 4 of its 10 claims. All
four were real. Every fix below is to code THIS round introduced.

1. THE SOFT VOICE CLAIMED TOO MUCH (refuted CLAIM 1).
   `REQ-01, (REQ-02), REQ-03 — REQ-05` took the range-reading voice and told
   the author "the line is already correct and nothing needs to change" — while
   `(REQ-02)` had been dropped by the selector, which does not strip
   parentheses.

   The channel choice is still right, and deliberately so: `(ADR-7)` and
   `(REQ-02)` are the SAME shape, so routing on "was anything unselected?" puts
   the false "could not be parsed" claim back on a line carrying a citation —
   the misroute fixed two commits ago. No rule can adjudicate this; the author
   can. So the voice stops asserting the line is correct (it now speaks about
   the SEPARATOR, which is all it has evidence about), and BOTH voices gained a
   factual clause naming ID-shaped text the selector skipped, with the reason
   (brackets are not stripped) and no verdict attached.

2. THE CAP SILENCED A LINE THAT USED TO WARN (refuted CLAIM 2).
   A 2049-char range token warned before this round and went silent after it:
   the "uniform cap" commit bounded the predicate and, with it, the warning.
   That is #3697's own defect, introduced by the fix for a nit.

   The cap bounds the WORK, not the warning. An over-cap token carrying `-` is
   now recorded as unclassified (a linear `includes`, never the unanchored
   regex the cap exists to keep off it) and gets its own voice: "could not be
   checked ... the REQ-ID selection on this line is unverified". Unclassified
   is reported, never treated as clean.

3. THE CAP WAS NOT UNIFORM (review MISSED finding).
   R2 capped the operator token but not its neighbours, so
   `<2049-char ID> .. <2049-char ID>` still ran REQ_ID_SHAPE_RE and BigInt over
   both endpoints unbounded. The glued rule had the same hole. Every
   participant is capped now.

4. PROPERTY P5 WAS VACUOUS (refuted CLAIM 5).
   It drew from a bare `fc.string()`, which over 500 samples produced max
   length 10 and ZERO inputs containing a REQ-ID — the loop body never executed
   an assertion. A containment property that never contains anything is a green
   test measuring nothing. The generator now interleaves real IDs with noise
   and the property ASSERTS it saw them (>50/500), so it can never silently go
   vacuous again. The free-form coverage it was actually providing survives,
   honestly labelled, as #3697-P6.

   The same finding refuted this round's claim that P2 distinguishes pre-round
   behaviour: every operator P2 uses was already in the pre-round operator set.
   P2 is a regression guard, and its comment now says so.

Also: docs/CLI-TOOLS.md repeated the broken channel claim verbatim (review
MISSED finding) and is corrected with the code.

Tests: #3697-9d (soft voice names the skipped ID, never claims the line is
correct), #3697-9e (over-cap token reported as unclassified, still warns),
#3697-9f (R2 and the glued rule cap their neighbours). #3697-B1/B2 now key the
boundary on the PREDICATE's verdict with `warn` asserted true at every length —
asserting `warn === false` at limit+1 was itself finding 2.

* docs(#3697): describe the third voice and the dash rule

Follow-on to the review-findings commit: that commit corrected the docs' claim
about the soft voice but left two things the code now does undescribed.

- There are THREE voices, not two. The over-cap voice ("could not be checked
  ... unverified") arrived with the fix for the review's CLAIM 2 and had no
  entry.
- Dash spellings require a full ID on both sides, and `..` / `…` / the word
  operators do not. That asymmetry is deliberate and load-bearing —
  `PREFIX-<digits><dash><digits>` is date- and sub-number-shaped — so a reader
  hitting `REQ-01-05` and getting silence has no way to find out why. The
  accepted cost (`REQ-01, REQ-02-05` unreported, bare `REQ-02-05` still
  reported) is stated rather than left to be discovered.

Documentation only; no behaviour change.

* fix(#3697): close the continuation review's findings

A continuation of the same adversarial reviewer, run against the reworked
round, refuted 6 of 7 claims. Four were real defects in this round's own work
and are fixed here; the other two are answered rather than changed, below.

1. THE SKIPPED-TEXT CLAUSE WAS ON ONE VOICE, NOT BOTH (refuted CLAIM A).
   The previous commit's message said both voices gained it. Only the soft
   return appended it. The assertive voice now carries it too — and, because
   that voice already names range tokens and inert residue under its own
   clauses, the note is filtered to what those did not already name. A warning
   that says the same token twice is one readers learn to skim.

2. THE CLAUSE'S WORDING WAS FALSE (also CLAIM A).
   It read "brackets and parentheses are not stripped". Square brackets ARE
   stripped by the selector — `[REQ-01, REQ-02]` is the documented form — so
   only parentheses qualify. Corrected in the message and in docs/CLI-TOOLS.md,
   which had inherited the same error.

3. THE OVER-CAP RULE STILL SILENCED A LINE (refuted CLAIM B).
   `oversizedTokens` filtered on `includes('-')`, which misses an over-cap
   OPERATOR: `REQ-01 <2049 dots> REQ-05` warned before this round, R2 declined
   to classify it once capped, and nothing reported it. That is the exact
   regression the field was added to close, one input over. Any token past the
   cap now counts — what it contains is irrelevant when we could not read it.

4. AND THEN OVER-REPORTED ONE (review MISSED finding).
   With (3) in place, a 2049-character CANONICAL REQ-ID was selected by the
   uncapped, fully-anchored selector AND flagged "REQ-ID selection on this line
   is unverified" — a contradiction inside one warning. A token the selector
   took was examined end to end, so it is excluded.

Two findings are answered, not changed:

  CLAIM C — the selector's own `REQ_ID_SHAPE_RE.test` is uncapped. True, and
  deliberate: this round does not touch what gets MARKED, and the pattern is
  anchored at both ends with no nested quantifier, so it is linear. The claim
  that "all predicate paths are capped" was too broad; the DETECTOR's are.

  CLAIM E — `REQ-01, REQ-02<dash>05` is silent for every dash. That is the
  documented, deliberate cost of holding dashes to the strict shape, and it is
  symmetric with ASCII, which behaved that way before this PR. The reviewer is
  right that "without losing a range spelling that should be detected" was too
  strong; a bare `REQ-02<dash>05` still warns.

Tests: #3697-9g (clause on the assertive voice, no repetition, bracket claim
true), #3697-9h (over-cap operator does not silence the line), #3697-9i (a
selected over-cap ID is never called unverified). #3697-9f is rebuilt — its
first version used the SAME id twice, so R2 could not have fired even uncapped
and it proved nothing; it now uses endpoints with a gap and fails when the
neighbour cap is removed.

Reversion control: all four fixes fail a named test when reverted in isolation
(#3697-9h, #3697-9i, #3697-9g, #3697-9f).

* fix(#3697): scope the over-cap exemption to what could actually pair

A second continuation of the same reviewer, against the reworked round,
confirmed the two claims that matter most and refuted three. This closes the
one real defect; the other two are answered below.

CLAIM J / CLAIM K (one defect, found from both directions). The previous
commit exempted EVERY selector-accepted token from `oversizedTokens`, on the
reasoning that the selector is uncapped and anchored so it examined the whole
token. True of that token's SELECTION — and not the same as "no rule was
suppressed by it". Two over-cap valid IDs either side of `..` are both
selected, so both were exempted, and R2 is capped: a line that warned before
this round went silent.

That is the third appearance of one class in this round — the cap suppresses a
check, and the suppression is not reported. Each fix for it over-corrected in
the opposite direction, which is why the rule is now stated in terms of what
was actually suppressed rather than in terms of the token: an over-cap token is
exempt only when it was selected AND nothing beside it could have paired with
it into a range (no range operator, no glued fragment, no second over-cap
token). Everything else is unexaminable and says so.

Two findings are answered, not changed:

  CLAIM M — the reviewer demonstrated, with driven evidence, a contextual rule
  that catches `REQ-01, REQ-02-05` while leaving `FY-2026-08` and `API-2-01`
  silent: recognise `PREFIX-a<dash>b` only when another SELECTED id on the line
  shares that prefix. That refutes this round's claim that the strict-dash
  trade was FORCED, and the claim is withdrawn — it is a design choice. The
  choice stands for this PR: the conservative rule is what ASCII already did
  before #3697, adopting a new contextual heuristic unreviewed at the end of a
  round is how the last three defects in this round were made, and #3697 asks
  for a warning rather than better range inference. Named here so the
  alternative is on the record rather than lost.

  Docs MISSED — CLI-TOOLS said every token over 2,048 characters "is not
  classified at all" and warns. Selection is not bounded; only range detection
  is. Corrected.

Confirmed by the same pass, and worth recording because they are the PR's
load-bearing promises: a 20,000-input comparison of the pre-extraction selector
against HEAD found `mismatches=0` (nothing about which REQ-IDs are MARKED has
changed), and the uncapped selector regex was measured linear from 100k to 800k
characters.

Tests: #3697-9f now asserts the range case is reported rather than silent, and
#3697-9j pins the exemption's scope in both directions. Reversion control:
restoring the blanket exemption fails both.

* fix(#3697): warn on zero selection, as the acceptance criterion asks

`Deferred`, `N/A`, `Pending`, `TBA` and `-` selected no REQ-IDs and stayed
SILENT, while three shipped artifacts said they warned: `docs/CLI-TOOLS.md`,
the `placeholderLed` census comment, and the advice string the command emits
to the user. The asymmetry was the tell — `Deferred (see ADR-7)` warned,
because the citation supplied the ID-shaped residue R3 required, while bare
`Deferred` did not. The claim was written into three places and never
executed once.

This is also #3697's AC-1b/AC-4 verbatim: "warn when `citedReqIds.length ===
0` while the raw capture is non-empty and not `TBD`".

R3b keys on the SELECTION being empty, never on what the prose means, so it
adds no free-text heuristic. It is deliberately not gated on ID-shaped
residue the way R3 is, and the negative space is what settles that: all
fifteen #2334/#2339 fixtures are held silent by non-zero selection or by
`placeholderLed`, and not one of them by the ID-shape gate — measured, not
argued. The gate was buying no negative space while costing the acceptance
criterion.

`tokens.length > 0` keeps an empty line and a comment-only line silent: the
tokenizer strips `<!-- ... -->` before splitting, so the shipped template's
own comment cannot reach the rule.

Selection behavior is unchanged. This warns; it never invents an ID.

Also extracts `warn` to a named const (round 3 review Minor 3) — this commit
adds a disjunct to exactly that predicate, and in the return literal a later
reordering would be a TDZ ReferenceError rather than a reader-visible error.

Tests: #3697-14 (six zero-selection lines warn and tick nothing, and the
warning names the TBD/None escape), #3697-14b (five placeholder spellings
stay whole-channel silent), #3697-14c (comment-only line stays silent).
Fail-first controls: all six #3697-14 cases fail against the pre-fix tree;
-14b and -14c pass at both ends, which is correct — they pin silence the
widening must preserve.

* fix(#3697): name the REQ-ID a glued delimiter dropped

`RANGE-01; RANGE-02` selects only RANGE-02 and marks only RANGE-02, with
`requirements_updated: true` — #3697's own half-success failure mode, reached
by one wrong delimiter, and silent before this rule. It is the issue's AC-1a
("a warning whenever the line contains ID-shaped content that the tokenizer
did NOT select") at the shape most likely to be typed by accident.

Round 4 review rated this Major rather than Blocker on the ground that the
case is indistinguishable from a parenthesised citation, since `(ADR-7)` also
shaves down to a bare ID. At the RAW token level it is distinguishable, and
that is what makes the rule shippable: `REQ-01;` is shaved of a trailing
DELIMITER, `ADR-7)` of a citation wrapper. R4 keys on that shave class and
requires the token to sit outside any parenthetical.

Measured before implementing: 0 false positives and 0 false negatives across
21 probes, including all fifteen #2334/#2339 negative-space fixtures. A first
cut without the parenthetical test scored 3 false positives — every one of
them a colon inside a citation (`(see ADR-7: section 3)`) — which is why that
test is the rule's boundary rather than an optimisation.

Adds the delimiter census the module did not have. The range-operator domain
was already censused; the comma-substitute domain was not. Swept 26
spellings: exactly two produce a silent under-selection, `; ` and `: `. Every
other spelling either selects both IDs or selects none and already warns. The
review hand-listed the semicolon; the colon is the sibling that sweep found,
and it fails identically.

`rangeReadingOnly` now excludes an R4 hit — the ambiguous voice claims nothing
was dropped, and must not speak for a line where something demonstrably was.

Tests: #3697-15 (four delimiter shapes warn, name EVERY dropped ID, and tick
exactly the unchanged selection), #3697-15b (three citation forms stay
whole-channel silent). Fail-first control: all four #3697-15 cases fail
against the previous commit's tree; -15b passes at both ends, pinning the
boundary the widening must not cross.

* fix(#3697): give the Requirements-line warning a stable machine kind

The warning's kind existed only in the prose of its message, so every consumer
and every test had to regex an English sentence — and rewording a message
silently un-asserted the tests that pinned it. Round 4 review Major 3.

The repo already had the settled seam for exactly these semantics.
`CONTEXT.md` records `diffLiveConfig` emitting `kind:'unverified'` for a
truncated scan, which is precisely this module's third voice; and
`WAVE_CLEANUP_WARNING` in `src/worktree-safety.cts` carries codes for the same
reason. ADR-3473 Decision 3 ("failure is a value") points the same way.

`formatRequirementsLineWarning` now returns `{ code, message }` instead of a
bare string, which also settles round 4 Nit 3 — `null` still means CLEAN, a
legitimate value, but the success arm is no longer a naked string one field
away from the shape the ADR standardises on.

The kind is carried ALONGSIDE the prose, never instead of it. `warnings[]` is
a documented `string[]` in `phase complete`'s JSON output, rendered by
execute-phase.md's "If has_warnings is true" step, so re-typing its elements
would be a breaking output-contract change for a shipped command. The code is
emitted as its own additive `requirements_line_warning` field, absent
entirely when the line is clean.

Vocabulary, exported so tests key on it rather than on string literals:
`req-line-misparse`, `req-line-range-reading`, `req-line-unverified`.

Tests: channel ROUTING in #3697-9/-9b/-9c/-9d/-9e/-9g/-10 now asserts the code;
message-content assertions stay where the user-visible wording is itself under
test. #3697-16 pins the code end-to-end through the CLI's JSON for four line
shapes and asserts warnings[] is still a string[]; #3697-16b pins that a clean
line emits no kind at all, because a field present on every run carries no
information. #3697-P4 holds kind-and-message-appear-together and
kind-is-in-the-declared-vocabulary over arbitrary input, so a channel added
later cannot ship without one.

* test(#3697): pin the divergence against the second parser of the same line

CLAUDE.md, KNOWN DEFECTS & ANTI-PATTERNS: "Generative Fix Divergence: when
sharing constants/arrays/parsers between parallel surfaces, add a parity
assertion test that fails if they diverge." Round 4 review Major 2.

`normalizePhaseReqIds` (src/gap-checker.cts) parses the SAME ROADMAP
`**Requirements:**` value — its own docblock says callers "may pass the
roadmap value through verbatim" — and diverges on four axes. Measured, not
inferred:

  line                                    phase complete      gap-checker
  RANGE-01..RANGE-05                      []                  5 IDs
  None (per ADR-7)                        []                  ["ADR-7"]
  (REQ-02)                                []                  ["REQ-02"]
  REQ-01a                                 []                  ["REQ-01a"]
  REQ-01, REQ-02                          both                both

This pins the divergence rather than removing it, which is the review's
second option and the correct one here: unifying the two would change what
`phase complete` MARKS, and "the ledger-writing set is byte-identical to base"
is the one invariant this PR holds fixed. Every axis is now asserted in BOTH
directions, so drift on either side fails here instead of widening silently.

The range axis is a DELIBERATE disagreement and is labelled as such — #3697
declines range expansion in terms ("I am not asking for range syntax to be
supported") while gap analysis adopted it under #1269.

The placeholder axis is the one worth reading twice: `None (per ADR-7)` is a
declared-empty line to `phase complete`, which reads the lead token, and a
one-requirement line to gap-checker, which strips parentheses first so the
citation survives its ID-shape filter. That is a citation being reported as a
requirement.

#3697-17b states the cost concretely: one line, five requirements in scope to
gap analysis and zero to phase complete. This PR is what makes that
contradiction visible, by finally giving the silent side a voice.

* fix(#3697): stop the skipped-text rider reporting a date, and close the 4b channel gap

Two round 4 review minors, both about a warning saying something it cannot
support.

MINOR 2 — false rider content. `REQ_ID_SUBSTRING_RE` is unanchored, so
`FY-2026-08` matches as `FY-2026` and lands in `unselectedIdShaped`.
`REQ_RANGE_TOKEN_RE`'s entire strict-dash arm exists to keep that shape
silent, and #3697-4 pins `RANGE-01 (target FY-2026-08)` as producing no
warning at all — but whenever some OTHER rule fired on a line that also
carried a date annotation, the rider told the author to "check whether any of
it is a requirement" about a date. Not a false warning, since the line was
warning anyway; false CONTENT, in the #2334 voice, through the side door.

Filtered at the MESSAGE rather than in the analysis: `unselectedIdShaped`
stays a faithful record of what the selector skipped — it is documented as a
fact that never routes — while the user-facing clause declines to assert
requirement-ness about a shape the design already ruled unadjudicable.
#3697-18b is the other half, so the filter cannot become a silencer: a
genuinely dropped REQ-ID is still named.

MINOR 1 — `#3697-4b` asserted only that the ASSERTIVE channel stayed silent,
so a regression routing `RANGE-01, TORANGE-05` into the AMBIGUOUS channel
would have passed. Whole-channel silence is not available on that fixture (the
pre-existing ghost-ID warning legitimately fires on the unregistered
`TORANGE-05`), so the precise assertion is that no Requirements-line warning
of ANY kind was emitted. The machine code added earlier in this round is what
makes that statable; before it, "both channels" could only have meant a second
prose regex.

* docs(#3697): record the Requirements-line seam in CONTEXT.md

CLAUDE.md names the CONTEXT.md glossary as a PR gate, and
`get_cochange_context(src/phase.cts, 45d)` ranks CONTEXT.md 4th at 25
co-changes — above src/init.cts and src/roadmap.cts. This PR introduced a
named seam, three warning kinds, a bound, a rule taxonomy and a deliberate
cross-parser divergence, and recorded none of it. Round 4 review Major 4.

The precedent is explicit rather than inferred: the directly analogous seam
is already there as `LIVE-CONFIG.GUARD.SEAM.truncation`, including its bound
and its boundary obligation — and that entry is the one this module's third
voice was modelled on.

Eight predicates, in the machine-oriented section beside it:

  .module                    the two exported functions and the code vocabulary
  .selector-identity         citedReqIds is byte-identical to base and is the
                             only thing reaching the ledger — a change to what
                             phase.complete MARKS is outside this contract
  .rules                     R1 / R2 / R2' / R3 / R3b / R4 / over-cap
  .kinds                     the three codes, and why they ride beside
                             warnings[] rather than inside it
  .cap                       2048, neighbours included, and the boundary rule
  .placeholder               the gate that actually holds the negative space
  .census-domains            both open domains with their NOT-reached members
  .gap-checker-divergence    the four axes, pinned not unified

The changeset type is `Fixed`, which exempts this PR from the docs/
co-change requirement — but the glossary gate is separate from that
exemption, and the 2048 cap in particular is a machine-canon-shaped fact
that until now existed only inside a source comment.

`docs/CONTEXT-INDEX.json` regenerated (269 predicates); lint:generated-sync
confirms all six targets in sync.

* docs(#3697): document what the command now does, in one changeset sentence

DOCS. The grammar section predated this round's two new rules, so it
under-described the behaviour it exists to make lookup-able:

- The placeholder paragraph enumerated three words; the rule is a DEFAULT.
  Any wording that selects no REQ-IDs warns, and the placeholders are matched
  as the LEAD token, so `None (per ADR-7)` and `**None**` are declared-empty
  too. The comment-only line is called out, because "any other wording" would
  otherwise read as covering the shipped template's own `<!-- ... -->`.
- The comma rule was implicit. `REQ-01; REQ-02` marks only REQ-02, and it is
  the quietest way to lose a requirement on this line — `requirements_updated`
  reads `true` either way — so it gets its own paragraph, with the
  parenthetical exemption stated beside it.
- The machine kind is documented where a consumer would look for it, with the
  instruction to key on the kind rather than the wording.
- The skipped-text note no longer implies it reports date shapes; it
  deliberately does not, and silently omitting that left the doc promising the
  behaviour this round removed.

CHANGESET (round 4 review Minor 4). CONTRIBUTING.md's format is
`**<Bold user-visible change>** — <symptom-led explanation>.` and both
canonical examples are one sentence; this fragment ran three. Now one, and
covering what the round actually delivers rather than only the range shape it
started from.

* test(#3697): keep phase.test.cjs off the docs-guard exemption fingerprint

A comment added earlier in this round named `docs/CLI-TOOLS.md` by path. The
docs-guard exemption ratchet (#3753 FIX 3) fingerprints literal `docs/`
references in exempt test files and fails when a new one appears, so that
comment turned four green gates red — `ci-docs-guard-registry` and the
registration lint — for a file that reads no documentation at all.

Caught by diffing the full suite's failing-name set against the same suite run
at `upstream/next` in a probe worktree: 33 of 37 failures reproduce at base
(install / config-home / shadowing tests under the sandbox HOME), and exactly
these 4 did not.

Rephrased rather than baselined. Adding the path to
DOCS_GUARD_EXEMPT_DOCS_PATHS is the sanctioned response when a test genuinely
starts READING a new docs path — the violation text asks the author to
re-confirm the exemption still holds. Nothing here reads documentation; the
guard matched prose. Baselining would have recorded a coupling that does not
exist and made the next reader wonder what phase.test.cjs does with
CLI-TOOLS.md. The comment still names where the contract is written, just
without planting a path string.

* fix(#3697): close four defects this round's own pre-push review drove

An adversarial cross-AI review of this round, run before the push, returned 6
CONFIRMED and 4 REFUTED. Every refutation was driven against the built tree,
and every one was a shape the author had not probed — the rules were correct
across the probe set and wrong just outside it.

(1) R4 FALSE POSITIVE, and it is the #2334 over-warning class arriving through
the rule added to close a different hole. `REQ-01, see ADR-7: section 3` fired:
`ADR-7:` is the same shave class as `REQ-01;`, and the parenthetical test does
not reach a BARE citation. The FP probe that scored this rule 0/0 only ever
tested the parenthesised form.

Fixed by requiring the dropped id's prefix to agree with a SELECTED id — the
module's own idiom, not a new heuristic: `reqEndpointsImplyInterior` already
demands an agreeing prefix for the same reason. Cost, stated in the census: a
dropped id whose prefix is on no selected id (`REQ-01, FOO-02: x`) stays
silent. Same trade the strict-dash rule takes — under-report a rare shape
rather than over-report a common one. Pinned as a declared blind spot by

(2) R4 FALSE NEGATIVE, on the DOCUMENTED form. `[REQ-01; REQ-02]` dropped
REQ-01 silently: the selector strips square brackets and R4's raw scanner did
not. The bracket spelling the shipped template recommends was the one shape the
rule could not see.

(3) The rider filter suppressed a REGISTERED requirement. `API-2-01` is a legal
requirement id — gap-checker's `parseRequirements` accepts it from
REQUIREMENTS.md — so a `\d+-\d+` filter hid a genuinely dropped requirement
behind a rule meant only to hide dates. Narrowed to a four-digit year segment.
The earlier #3697-18 case asserting `API-2-01` should be suppressed is REMOVED,
and the removal is recorded in place: its premise was refuted, it was not
inconvenient.

(4) An INVISIBLE line warned. A lone U+200B carried a token to the parser while
reading as empty to the author, so R3b fired with nothing on screen to explain
it. Zero-width and format characters are now stripped — stripped rather than
treated as delimiters, because splitting on one would fabricate two fragments
out of one ID.

Also corrects the documentation the same review found overstated: the line is
split on commas AND whitespace, and the ID shape is matched case-insensitively,
so `REQ-01 REQ-02` and `req-01, req-02` both select and neither warns. That was
pre-existing selector behaviour; this round is the one that asserted the docs
were true of it.

Tests: #3697-19 (four invisible-only shapes), -19b (embedded zero-width is
stripped, not split on), -19c (three citation forms), -19d (both bracket
spellings), -19e (both halves of the rider boundary), -19f (the declared blind
spot), -19g (the two documented tolerances). 500 tests in phase.test.cjs, 0
failures; lint:ci clean.

* fix(#3697): generalise the drop rule, and stop the invisible fix hiding a drop

The pre-push review's continuation refuted six of seven follow-up claims. The
first one is the one that mattered: the invisible-character fix committed in
c7dce173a INTRODUCED #3697's own defect. Stripping zero-width characters from
the detector wholesale made `REQ-01<ZWSP>, REQ-02` go SILENT — the selector
really does drop REQ-01, and the strip removed the only evidence of it. The
test written alongside asserted the tokens and the empty R4 result and never
asserted `warn`, so it DOCUMENTED the bug rather than catching it; that
omission was the reviewer's own MISSED finding.

An invisible is two different questions about one character, and the fix is to
stop conflating them: absence-of-content for the empty test, DECORATION on a
token for the drop rule. Neither is a reason to delete it from the line.

R4 is generalised accordingly, because the continuation drove four more shapes
a trailing-delimiter-only regex could not see — `REQ-01 ;REQ-02`,
`REQ-01 :REQ-02`, `**REQ-01;** REQ-02`, the backticked form — plus
`**REQ-01**, REQ-02`, where emphasis alone defeats the selector. These are one
class: decoration on a token the selector then cannot take. One rule, not four
patches; patching them individually is how a list stays short and wrong.

PARENTHESES ARE NOT DECORATION, and the suite caught me learning that: shaving
them made `REQ-01, (REQ-02), REQ-03 — REQ-05` report a glued delimiter that was
never there and broke #3697-9d's channel routing with it. A parenthesis is this
rule's citation marker.

The rider stops adjudicating an undecidable shape. `API-2-01` is a legal
requirement id and `API-2026-08` is too, while `FY-26-08` and `FY-2026-08-15`
are dates — no regex separates them, and both filters this round tried scored a
miss in each direction. It now NAMES the token and states the ambiguity, which
is the same thing the two warning voices already do about a range separator.
Filtering hides a real dropped requirement; reporting it bare asks the author
whether a date is a requirement; saying "this may equally be a date" does
neither.

The census and the docs are corrected to what the code does, including the part
that is NOT complete: the prefix gate does not stop a citation that SHARES a
selected prefix (`ADR-01, see ADR-7: sec 3` fires), and nothing at token level
separates that from a real drop. A prose heuristic on "see" is the free-text
detector this module exists to avoid, so the honest move is to say so.

CLAIM 17 — the invariant that actually matters — came back CONFIRMED on a
20,000-run fast-check property over arbitrary Unicode: `citedReqIds` is
identical to upstream/next's for every input, and marking is untouched.

513 tests in phase.test.cjs, 0 failures; lint:ci clean.

* fix(#3697): gate the drop rule on evidence, and stop an unmatched paren swallowing the line

Third pass of the round's own pre-push review, scoped to regression-hunting
rather than further polish. Three findings, all driven, all mine.

R4 OVER-WARNED on markdown styling. `REQ-01, see **REQ-7** for context` claimed
a dropped requirement: the previous cut treated any shaved decoration as
evidence, and emphasis is not evidence. Nothing separates that line from
`**REQ-01**, REQ-02` meaning to list one, so the rule now requires a positive
signal — a glued `;`/`:` (a list separator was INTENDED) or an invisible (the
token is CORRUPTED; nobody types one on purpose). Emphasis alone falls back to
the skipped-text rider, which names the id without asserting a drop, exactly as
`(REQ-02)` is handled. That is the #2334 class caught one cut before shipping.

R4 UNDER-WARNED on `**REQ-01**; REQ-02` — one shave pass cannot reach a wrapper
sitting behind a delimiter. Shaves to a stable point now.

The range OPERATOR lost its invisibles handling. `REQ-01 <ZWSP>..<ZWSP> REQ-05`
went silent, because the previous commit removed the invisible strip from BOTH
the tokenizer and R4 when only R4's was wrong. An invisible is two questions
about one character: for the classification rules it is noise and is stripped
from the token; for the drop rule it is the evidence and must survive on the
raw line. Stripping in both places hid a dropped id; stripping in neither hid a
range. The reviewer's MISSED finding named the missing control — regression
tests covered invisibles inside ids and not beside operators — and #3697-19i is
that control.

UNBALANCED PARENTHESES swallowed the line. `REQ-01, (note REQ-02; REQ-03`
reported nothing: a running-depth counter left the unclosed `(` open through
end-of-line, so every genuine drop after it inherited citation immunity. A
parenthesis confers that immunity only as part of a MATCHED span now — an
unmatched one is a typo, not a citation.

CLAIM 22 re-confirmed on a fresh 20,000-run property over arbitrary Unicode:
`citedReqIds` identical to upstream/next, marking untouched, warnings appended.

522 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite carries zero
head-only failures against a probe worktree at upstream/next.

* fix(#3697): make delimiter ADJACENCY the rule, and delete matched citations outright

Fourth and final pass of the round's own pre-push review. Three findings, and
they shared one root cause, so this is a narrower rule rather than a longer list
of shapes.

TOKEN-WIDE PAREN IMMUNITY LEAKED. `REQ-01, REQ-02;(note) REQ-03` is a single
whitespace token, so a matched parenthetical inside it conferred immunity on the
`REQ-02;` sitting OUTSIDE the parens, and the drop went silent. Matched spans
are now deleted from the line outright — which states what is actually meant,
that for this rule a citation is not on the line — and an UNMATCHED paren is a
typo that confers nothing. That also retires the running-depth counter whose
previous bug was the mirror image: an unclosed `(` swallowing the rest of the
line.

DECORATION WAS TESTED TOKEN-WIDE, so `REQ-01, see **REQ-7**; next topic` was
reported as a dropped requirement. It is a citation with sentence punctuation.
The rule is now ADJACENCY: styling is stripped, then the `;`/`:` must be
touching the id. `REQ-01;`, `;REQ-02` and `**REQ-01;**` qualify;
`**REQ-01**;` does not, because outside the styling that character is
punctuation. An invisible needs no adjacency test — nobody types one on
purpose, so anywhere in the token it is corruption rather than intent.

`**REQ-01**; REQ-02` therefore goes silent, and the test row asserting
otherwise is inverted rather than deleted quietly: it was added one commit ago
on the reasoning this pass refuted, and nothing distinguishes it from
`see **REQ-7**; next topic`.

Worth recording plainly: three successive cuts of this rule fired on a
citation, and each fix was a narrower definition of EVIDENCE, never a longer
list of shapes. The list-lengthening instinct is what produced the bug each
time.

The review's last MISSED finding named the missing control — the paren tests
all surrounded matched spans with whitespace, so none covered a span sharing a
token with an id outside it. #3697-19j carries both directions now.

526 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite zero
head-only failures against a probe at upstream/next; the invariant that
`citedReqIds` is identical to upstream re-confirmed on 20,000 arbitrary
Unicode inputs.

* fix(#3697): state R4's real boundary, and stop the over-cap voice masking a drop

Two defects, both found by this round's own pre-publication body claim-audit.

1. A DEMONSTRATED drop was discarded by the unverified voice. On
   `REQ-01, REQ-02: <2049 chars>` the analyzer names REQ-02 in
   delimiterDroppedIds and the formatter then reported `req-line-unverified`,
   whose message never mentions it — the one actionable finding masked by the
   token beside it. The over-cap channel now excludes a line carrying an R4
   hit, exactly as rangeReadingOnly already did and for the same reason: that
   voice's whole claim is that nothing could be checked, and R4 has already
   checked something. The assertive channel still carries the over-cap rider,
   so nothing about the cap is traded away. Pinned by #3697-19l, which fails
   against the pre-fix build and nothing else does.

2. Three shipped artifacts asserted behaviour the code does not have — the
   same class as this PR's round-4 blocker, re-committed. CONTEXT.md's rules
   predicate, the CLI tools reference, and the warning's own advice string all
   listed markdown emphasis as an R4 trigger. It is not: styling is shaved
   BEFORE the test and tolerated around an id, never a trigger on its own, so
   `**REQ-01**, REQ-02` and `**REQ-01**; REQ-02` are both silent. The trigger
   is exactly a glued `;`/`:` or an embedded invisible.

   The census predicate was wrong in a second way. Its 26-spelling separator
   sweep found only `;` and `:` because the sweep was SYMMETRIC-ONLY and
   therefore biased: one-sided attachment drops silently for every punctuation
   outside the set — `/ | & + . > \` and the full-width and non-ASCII forms
   `; , ؛` all measured silent. The domain is wide open and R4 covers two
   characters of it. Said plainly in all three places rather than widened
   here: every previous widening of this rule first fired on a citation, so it
   is not done blind at the end of a round.

Both blind spots are now PINNED as tests (#3697-19m styling-only, #3697-19n
one-sided separators) so the documents and the code cannot drift apart again —
which is what the round-4 blocker asked for.

tests/phase.test.cjs: 542 tests, 542 pass, 0 fail, 0 skip. lint:ci rc=0.
Both CONTEXT-INDEX consumers regenerated.

* fix(#3697): re-sweep the separator census properly, and say what it really found

The round-4 census in src/phase.cts concluded "exactly two — `; ` and `: `"
from a 26-spelling sweep. That conclusion was forced by how the sweep was
built, not by the code: it swept the ONE-SIDED form (`REQ-01; REQ-02`) for the
semicolon and colon, and only the BARE and SYMMETRIC forms (`|`, ` | `) for
every other separator. Different members of the domain were tested in
different shapes, so no other answer was reachable. Caught by this round's
pre-publication claim-audit of the response comment, reading the census
comment against its own swept list.

Re-swept fully crossed and driven through the built artifact: 21 separators x
{bare, trailing-space, leading-space, both-spaces} = 84 combinations. 26 select
both ids, 24 under-select and already warn, and 34 UNDER-SELECT SILENTLY. All
34 are one shape — a separator glued to exactly one of the two ids, e.g.
`REQ-01/ REQ-02` or `REQ-01 /REQ-02` — for every punctuation except `,` and
the `;`/`:` that R4 covers.

So R4 covers TWO CHARACTERS of a wide-open domain. That is now what the census
comment, the CONTEXT.md census-domains predicate and the CLI tools reference
all say. The set is deliberately not widened here: three successive cuts of
this rule fired on a citation, and a fourth at the end of a round with no
adversarial pass is how each of those got in.

Second false passage in the same block: styling-only decoration was described
as "left to the skipped-text rider, which names the id". A rider only exists
inside a message, and a message only exists once some rule sets `warn` — so on
a line where nothing else fires, `REQ-01, **REQ-02**` is wholly silent.
Describing it as handled reads as coverage. #3697-19m already pins the silence.

so the test matches the documented claim.

tests/phase.test.cjs: 552 tests, 552 pass, 0 fail, 0 skip. lint:ci rc=0.
Both CONTEXT-INDEX consumers regenerated.

* chore(#3697): regenerate both CONTEXT-INDEX.json after rebasing onto next

Rebased onto next @ f4fefb0be. The two generated indexes conflicted on the
replay and were resolved by regenerating, not by hand-merging:
`npm run gen:context-index` for docs/CONTEXT-INDEX.json and
`node examples/dynamic-context-management/gen-context-index.cjs --write` for
the example's copy. Against next, each now differs only in the eight
PHASE.REQ-LINE.SEAM.* predicates this PR adds (plus the PHASE class and the
count); every base-side change (the SEAM.* predicates, the ADR-3942 value
rewrites) is carried. `lint-example-parser-parity` and
`gen-context-index --check` both pass.

* fix(#3697): an over-cap token outranks the ambiguous range voice

Round 7 review, Minor 1. `rangeReadingOnly`'s guard conjunction checked
`hasGluedRangeFragment`, `inertIdShaped` and `delimiterDroppedIds` but not
`oversizedTokens`, so a line carrying a clean, fully-selected spaced range
*and* an unrelated token past the 2048-char scan cap was coded
`req-line-range-reading` — a code CONTEXT.md's PHASE.REQ-LINE.SEAM.kinds
predicate documents as "nothing was dropped" — over a token no rule (R1-R4
all skip over-cap tokens) had ever examined. Since the PR tells machine
consumers to branch on `.code` rather than parse prose, that is a false
"nothing to verify further" signal.

The review's suggested fix was to add `oversizedTokens.length === 0` to the
conjunction. That clause is right and is here, but on its own it routes the
line to the ASSERTIVE channel: `req-line-misparse`, whose message says the
line "could not be parsed as a comma-separated REQ-ID list" on a line where
every ID present was in fact selected. That is the #2334 over-warning class
this module's own channel-selection docblock exists to prevent — a false-clean
code traded for a false-assertion one. So the correct destination is
`req-line-unverified`: the line was not CHECKED, which is not the same as
clean, and nothing on it demonstrably failed to parse either.

Both non-assertive voices were carrying their own inline copy of the same
"nothing was demonstrably dropped" conjunction, and that duplication is what
let them drift: `rangeReadingOnly` omitted the cap, while the over-cap channel
excluded a spaced range wholesale via `!hasSpacedRange`. Extract it once as
`nothingDemonstrablyDropped` and have both read it. The new predicate is a
strict superset of the old `!hasSpacedRange` guard — `spacedRangePairs.every()`
is vacuously true when no spaced range fired — so the over-cap channel's
behaviour on every line without a spaced range is unchanged, and R2 firing on
an endpoint the selector did not take still routes to the assertive channel.

Exactly one input class changes routing: a clean fully-selected spaced range
beside an unexamined over-cap token, which moves from `req-line-range-reading`
to `req-line-unverified`. Pinned by `#3697-19n` (the twin of `#3697-19l` on
the other side of the boundary — there a demonstrated drop outranks the
unverified voice, here the cap outranks the ambiguous one), with `#3697-19o`
as the negative control asserting a clean range with nothing over the cap is
still a range reading.

* docs(#3697): state the warning-code precedence, and what the cap condition actually is

Two surfaces, one point. The round 7 finding cited CONTEXT.md's
PHASE.REQ-LINE.SEAM.kinds predicate as the documentation of what
`req-line-range-reading` claims, and it was right to: that predicate said "R2
alone fired on selected endpoints; nothing was dropped" with no mention of the
scan cap, describing a line the code could not distinguish from one carrying a
token it never examined.

The range reading is the weakest of the three claims and yields to the other
two: a demonstrated drop makes the line a misparse, and a token the cap left
unclassified makes it unverified. `docs/CLI-TOOLS.md` gains that sentence; the
CONTEXT.md predicate gains it plus two precision points that this round's own
pre-push adversarial review extracted over three passes, each with a driven
counterexample I reproduced before acting on it:

  * "nothing was dropped" overstates the rule. The discriminator is RULE-scoped
    by design (round 3, Major 3), so that a parenthesised ID-shaped token does
    not re-open the #2334 over-warning class — `(REQ-02)` is indistinguishable
    from `(ADR-7)` at token level and is carried by the skipped-text rider, never
    by this code. `REQ-01, (REQ-02), REQ-03 - REQ-05` selects three, names REQ-02
    as skipped, and is still a range reading. The predicate now says "no rule
    named a dropped ID", which is what the code tests.

  * The deferral condition is `oversizedTokens` being non-empty, NOT the presence
    of a token past the cap. Those differ: a long token the selector itself took
    can be exempt, because selection is uncapped and anchored and such a token
    was therefore examined. `RANGE-01 - RANGE-05, R-<2047 sevens>` yields
    `oversizedTokens=[]` and stays a range reading. Two earlier attempts to
    characterise WHEN the exemption applies were both refuted — the neighbour
    test admits any non-short neighbour, not just a range operator — so the
    predicate now states the condition and defers the exemption's own rule to
    SEAM.cap rather than paraphrasing it a third time.

Verified after the edit: deferral holds if and only if the cap left a token
unclassified, across all three counterexamples plus controls, and an exempt
selector-taken long token is exhibited. No behaviour change — predicate text,
one CLI-reference paragraph, and the two regenerated indexes. Predicate count
unchanged at 285 across 22 classes, 0 duplicate ids; lint-example-parser-parity
and both `--check` generators pass.

* test(#3697): rename the round 7 regression pair — 19n was already taken

Self-found immediately after the push, before anything was published to the
review thread. The two tests added this round were named `#3697-19n` and
`#3697-19o`, and `#3697-19n` was already in use: it is the declared-blind-spot
case for one-sided separators in both attachment directions, generated inside a
loop with a computed label, which is why a grep for a literal `test('#3697-19n'`
did not find it. The PR body's own *Declared blind spots* list already refers to
`#3697-19n` with that meaning.

Nothing failed. Duplicate test names do not error, and the suite stayed green at
567/567 — which is the argument for fixing it rather than against. Two concrete
costs: any TAP name-set differential collapses same-named tests under `sort -u`,
so one of the two becomes invisible to exactly the did-not-run and pass->fail
checks that name-set comparison exists to perform; and a reviewer reading
"#3697-19n" in the body now gets a different test than the one the body means.

Renamed to `#3697-19p` (over-cap beside a clean range) and `#3697-19q` (its
negative control), the next free ids in the series; the pre-existing `#3697-19n`
is untouched at its original 4 occurrences. Cross-references inside the renamed
block were updated with them. Negative control re-run under the new ids: 19p
still fails against pre-fix source and passes after, 19q passes at both ends.

1a358ce0fd feat(#2761): bracket-tolerant read path — roadmap/validate/verify/state recognize bracket ids (epic #612 PR-2) (#2867)
* feat(#2761): gated heading-intro selection + one bracket identity grammar

Foundation. Two owner-level changes plus a federated convention resolver; no
reader consumes them yet.

1. GATED SELECTION, not an ungated widening.

   Widening every heading matcher requires the claim "no legacy ROADMAP contains
   a `[CODE.MM]` bracket followed by a digit", and that is false:
   `### [RFC.2119] 5:`, `### [v1.0] 2024:`, `### [ADR.612] 3:` and
   `### [ISO.8601] 2026:` are ordinary headings, and a widened reader claims each
   as a phase — moving phase_count and total_phases and adding W006 on projects
   that never opted in. No narrowing rescues it: the premise is about documents
   we do not control.

   `phaseHeadingPrefixSrcFor(baseline, convention, capturing?)` selects the
   pattern SOURCE at construction time. A project whose resolved
   `phase_id_convention` is not exactly 'bracket' compiles the same source string
   it compiled before. `baseline` is explicit because whether a site spells the
   any-bracket prefix or a bare `Phase\s+` is a fact about that site's history:
   handing the wider grammar to a bare site retro-grants tolerance it never had,
   in both directions — warnings appear, and a warning that fires today vanishes.

   Both bracket forms CAPTURE. `[GSD.999] Phase 07:` previously matched through
   the base alternative, which captures nothing, so a reader saw no bracket, fell
   back to the legacy token rule, and counted a labeled icebox heading while
   excluding the label-less one beside it — two derivations of one ROADMAP
   disagreeing.

2. ONE bracket identity grammar, one width rule.

   The milestone width is reconciled with the emit validator: pad2 output, so
   two digits or 3+ with no leading zero. Earlier spellings diverged in both
   directions — admitting `002`, which the validator rejects, and a bare `0` pad2
   never produces — and the section recognizers accepted `[GSD.2]`, which SCOPED
   a milestone no phase heading could then resolve into, recreating the
   on-disk-count fallback this epic removes. An unpadded bracket is now uniformly
   malformed: it scopes nothing, bounds nothing, sections nothing. W005 on its
   directories is the surfacing signal.

   The milestone field is boundary-anchored, so a malformed run cannot match by
   its prefix (`GSD.002-01` read as sentinel `00`). Recognition stays
   case-insensitive because readers compile `/i`, but identity helpers match
   `[A-Z]`, so a captured id is folded first — otherwise `### [gsd.999] 07:`
   failed every sentinel test. The qualified key shares the width, the `(?=-|$)`
   boundary and the single-sub-phase shape of the directory token, because
   phaseTokenMatches returns unconditionally on a qualified hit: a key matching a
   directory isPhaseDirName rejects would be a final wrong answer.

3. resolvePhaseIdConvention federates workstream -> root exactly as
   config-loader does — including that root is a fallback only when a WORKSTREAM
   is active, so a project-scoped directory stands alone. loadConfig cannot serve
   this: it merges against CONFIG_DEFAULTS and drops keys it does not know, and
   this key is not among them. It governs the bracket-selection reads ONLY.

PHASE_HEADING_PREFIX_SRC is left byte-identical: PR-1 shipped it, nothing
consumes it, and it is superseded rather than redefined.

* feat(#2761): roadmap.cts selects its heading grammar from the convention

Six matchers build their intro through the gated selector, and
cmdRoadmapAnalyze / cmdRoadmapGetPhase / getRoadmapPhaseWithFallback each
resolve the convention ONCE per command and thread it down.

Three sites take the any-bracket baseline (they already tolerated
`[anything] Phase N`); three take label-only (they spelled a bare `Phase\s+`).
Handing the wider grammar to a label-only site retro-grants tolerance it never
had — and not only by adding matches: on a legacy repo an unchecked
`- [ ] **[v1.0] Phase 05: Thing**` bullet would start SUPPRESSING the W006 that
fires today.

Sentinel handling under bracket ADDS a rule rather than replacing one: a
bracketed heading is a sentinel when its bracket milestone is reserved
(`### [GSD.999] 01:`) OR when its token is, so the engine-wide 0/999 backlog
convention keeps applying to `### [GSD.02] 999:`. Replacing the token rule let a
mid-migration ROADMAP — bracket headings plus a legacy backlog block, exactly
the content this epic targets — add entries to the progress denominator. The
captured id is folded before the identity test, so a lowercase
`### [gsd.999] 07:` is excluded too.

The DIRECTORY read is threaded too. `cmdRoadmapAnalyze` resolves the convention
once and hands it to all four of its heading/checklist patterns, but the single
`phaseTokenMatches` call that decides `disk_status`, `plan_count`,
`summary_count`, `has_context` and `has_research` was left two-argument — so
every canonical `{CODE}.{MM}-{PP}-slug` directory read as `no_directory` with
zero counts, on the PR's own headline verb, while the SAME build resolved those
same directories correctly in three other places on the same repo (W006/W007 via
phaseTokenFromDir, `state json` via the milestone filter, and the W021
milestone-complete read through this very helper's three-argument form). It
failed ONLY for the directory shape the convention exists to name: a
mid-migration bracket repo carrying legacy `01-one` dirs resolved fine, which is
why nothing caught it. Measured, bracket vs its flat-legacy twin:
`[["01","no_directory",0,0],["02","no_directory",0,0]]` against
`[["01","complete",1,1],["02","planned",1,0]]`.

The oracle is the twin, computed in the same test run, plus exact literals —
`grep disk_status tests/adr-612-*` was zero hits before this, so neither the fix
nor a future regression had any gate at all.

Disclosed: a ROADMAP written in bracket form before config.json is switched
reads as empty rather than mis-counted. Silent invisibility during the migration
window is the deliberate trade against claiming phases on projects that never
opted in.

* feat(#2761): validate.cts selects its grammar; gated directory recognition

The W006/W007 feeders take the resolved convention as a threaded parameter.
These sites carry the letter-tolerant `[\w][\w.-]*` capture, which makes them
where an ungated widening does the most damage: `### [RFC.2119] 5:` enters
roadmapPhases as a phantom and becomes a W007 "in ROADMAP.md but no directory on
disk" on a project that never opted in.

buildRoadmapPhaseVariants also surfaces the tokens borne ONLY by sentinel-bracket
headings. Surfaced rather than filtered in place because roadmapPhases feeds both
a membership check and a missing-directory warning, and only the latter should
ignore an icebox item.

That set is OCCURRENCE-AWARE, and the subtlety is load-bearing: roadmapPhases is
a TOKEN set, so `[GSD.999] 01` and `[GSD.02] 01` collapse to one entry. Keying
suppression on the token alone let an icebox heading silence a REAL phase that
happens to share its number — a false negative strictly worse than the warning it
removed. A token is suppressed only when no non-sentinel heading bears it.

Directory recognition is added as gated FUNCTIONS beside the exported RegExp
constants, which stay byte-identical: the `{CODE}.{MM}-` prefix is
string-indistinguishable from the letter-prefixed-decimal family this repo
documents as ambiguous, and folding a branch in changes those constants' answers
on exactly that family. A RegExp constant has nowhere to attach a gate.

The recognizer mirrors the emit grammar and delegates the token to the canonical
owner, so recognizer and resolver agree on rejected input as well as accepted.
Both functions throw on a non-string, matching the call pattern they replace.

buildRoadmapPhaseVariants' CHECKLIST scan is capturing, like its heading twin
and like the sibling checklist scan in roadmap.cts, and for the reason that one
states: the bracket id has to ride along or the sentinel filter is blind to
`- [ ] **[GSD.999] 01: Icebox**`. Left un-capturing, the scan called every
checklist token REAL, and the occurrence-aware un-suppression loop then deleted
the icebox token the HEADING scan had correctly marked sentinel — so `validate
consistency` warned that a bracket ICEBOX phase had no directory, in the HOUSE
ROADMAP shape where an icebox appears as both a bold bullet and a detail
heading. `validate health` stayed silent on that same repo, so the two verbs
disagreed — which is the disagreement `sentinelPhases` exists to close.

Both directions are pinned, because the failure mode of a careless fix here is
the opposite one: a real phase sharing a sentinel's token must still warn. It
does, in all four shapes that attack it (sentinel heading + real bullet,
lowercase sentinel, sentinel after the real heading, colon-less bullet).

* fix(#2761): count bracket headings, and retire them, in both derivations

Both `total_phases` derivations select their grammar from the resolved
convention, in one commit — cmdStateSync already carries the comment that it
mirrors buildStateFrontmatter "so both report consistent percents (#3242 Bug B)",
so teaching one and not the other ships that divergence.

The #1514 retirement filter widens WITH the counter it protects. The canonical
gesture strikes the checklist BULLET and leaves the detail heading intact, so a
bracket-form retirement went undetected and the phase stayed in the denominator
forever. That is half a fix alone: the retired key is compared against
phaseKeyFromDir, which called extractPhaseToken with no convention. Both halves
land here.

Under bracket the sentinel token rule composes as the full engine set {0, 999},
so this counter agrees with `roadmap analyze`, which has always excluded both —
otherwise the two derivations report different numbers for one ROADMAP and the
changeset's "excluded from every count" is false as written. The LEGACY path
keeps its pre-existing 999-only rule: widening it there would move legacy totals,
so the two stay split off the bracket path exactly as they are today.

The sync-side assertion reads the PERCENT sync writes into the STATE.md body, not
the frontmatter total_phases. Sync's own counter never reaches that field — the
read derivation writes it — so asserting the frontmatter after a sync measures the
read path twice and lets a mutation to the write-path guard survive.

* feat(#2761): verify.cts bracket-coherence W021 + selected milestone-complete read

The shipped milestone-prefixed W021 gate keeps its ROOT-only config read,
verbatim base semantics. Federating it silently moved a legacy convention's
answer in BOTH directions on workstream repos — a W021 that fires at base
vanishing, and one that is silent at base firing. resolvePhaseIdConvention
governs the new bracket-selection reads only.

B6, the milestone-complete check, keeps its ungated POSTURE (bug-557 pins it
with an empty config) but selects its grammar from the convention. Inferring
'bracket' from the shape of a matched bracket ran a repo-failing check against a
legacy ROADMAP that merely contained `### [RFC.2119] 5:`. Directory resolution
widens with the heading read, so a bracket repo whose phases are on disk stays
silent, and a bracket sentinel is not reported as unstarted.

checkBracketCoherence is advisory and gated. Anchored to tokenizeHeadings so
fenced examples cannot warn and heading level is structural. Its scope rules each
close a way it silently did nothing or fired wrongly: only a genuine MILESTONE
heading opens or closes a section (a `### Notes` used to reset scope and disable
both sub-checks); a legacy `## v3.0` DOES close it; an M-NN or letter-suffixed
phase heading raises missing-bracket and CONTINUES; a bare `#### 2026:` is not a
phase; the full h2-h6 range is processed. Its section recognizer shares the one
milestone width, so an unpadded `### [GSD.3] 05:` can no longer be a phase to the
id grammar and a section to the section grammar at once, silently re-scoping
every warning after it.

validate consistency suppresses bracket sentinels in its missing-directory
warning — the two verbs disagreed, health suppressing via notStartedPhases while
consistency did not. The legacy reading is untouched, including its pre-existing
wart that `### Phase 999:` still warns there.

* fix(#2761): scope the milestone by its bracket; select the disk-side filter

Two roadmap-parser reads, both of which made a bracket project's totals track
the disk instead of the ROADMAP.

The ADR pins the bracket milestone heading as `## [GSD.02] Foundation` — a name,
no version — but scoping matched STATE's `milestone: v2.0` STRING against a
heading, so the canonical form matched nothing and total_phases fell back to the
directory count. The rule was re-derived in THREE places: extractCurrentMilestone
plus two `milestoneBounded` guards; fixing one left the others falling back
regardless, so they are now one gated helper. It matches the CANONICAL padded
spelling only — accepting `0*N` bounded a milestone whose phases were invisible,
which un-suppressed a progress percent computed off an unscoped disk count.

getMilestonePhaseFilter's heading scan becomes the 14th selected read. On a
bracket ROADMAP it collected nothing, so the filter degraded to pass-all and
buildStateFrontmatter counted every other milestone's directories — making the
bracket convention strictly worse than the M-NN one it supersedes on the property
that matters most: totals must track the ROADMAP, not the disk.

The DIRECTORY side of that same filter is selected with it. Teaching only the
heading scan was half a fix and a worse one: `milestonePhaseNums` became
non-empty, so the pass-all degrade stopped firing, but no bracket directory could
satisfy the three legacy dir checks (numericRe fails on `GSD.02-05-five`, the
custom-id match captures the project code `GSD`, and stripProjectCodePrefix does
not strip a dotted prefix). Every bracket directory was rejected, and
completed_phases / total_plans / completed_plans / percent all collapsed to 0
while `state sync` went on writing a percent off the unfiltered disk — `state
json` reporting 0% on the same repo, in the same second, that STATE.md's body
called 67%. That is the #3242 Bug B divergence this PR exists to avoid, and
total_phases could not show it: `Math.max(phaseDirs.length, roadmapPhaseCount)`
floors it at the ROADMAP count no matter how many directories are rejected.

The dir side matches on the milestone-QUALIFIED id, delegated to the owner's
gated `phaseTokenMatches(dir, id, 'bracket')`, not on the bare token: READING-B
puts the milestone in the bracket, so `GSD.01-01-old-one` and `GSD.02-01-one`
share the token `01` and only the qualified key separates them. The qualified ids
are kept in their own set — a hyphen in `milestonePhaseNums` would flip
`roadmapUsesHyphenedIds` and silently move the LEGACY dir path on a bracket repo
— and the branch is ADDITIVE: on a miss it falls through to the three legacy
checks, so a bracket project carrying legacy-shaped directories reads unchanged.

Both are resolved lazily and gated, so the legacy path pays neither a config read
nor a second scan and cannot change answer. The scoping call is also GUARDED:
resolvePhaseIdConvention reaches planningDir, which throws a plain Error for a
GSD_PROJECT/GSD_WORKSTREAM segment carrying `/`, `\` or `..`. At base the only
planningDir call in extractCurrentMilestone sits inside the STATE-read try, so
the function returned normally on such an environment; an unguarded one here let
that escape and broke the never-throws invariant that getRoadmapPhaseInternal and
getMilestoneInfo three hundred lines below carry #2245 / ADR-227 notes about.
Unreachable through the CLI — GSD_WORKSTREAM is rejected up front by the
workstream-name policy and GSD_PROJECT throws identically at base — but reachable
by any in-process embedder, which is precisely who that invariant is for. The
filter's own resolve call was already inside its try and is unaffected.

The milestone-qualified key is formed only for a token that is itself a bracket
phase token. `${bracketId}-${token}` is a string SPLICE, so a mid-migration
heading carrying an M-NN label — `### [GSD.02] Phase 02-01:` — spliced to
`GSD.02-02-01`, which the qualified-key grammar reads as milestone 02 / phase 02:
the `-01` truncated, both such headings collapsing to one key, and the heading
claiming `GSD.02-02-two`, the directory it does NOT name, while rejecting
`GSD.02-01-one`, the one it does. The guard drops those headings back to the
unqualified legacy path, restoring the base ACCEPTANCE VECTOR exactly — pinned
against the milestone-prefixed reading of the same ROADMAP, which is
base-identical on this shape.

Scoped precisely, because the fixture moves one number that the guard does not
touch: `total_phases` on it reads 1 at base and 2 here. That is the bracket
heading COUNT this PR exists to add, not the splice — measured identical with and
without the guard, and identical to what the canonical `### [GSD.02] 01:`
spelling does on the same fixture (both read 2 with zero directories on disk,
where base reads 0). The claim is base-equivalent ACCEPTANCE, not a
base-equivalent reading.

One consequence is stated rather than fixed: a heading whose token carries a
hyphen still puts that hyphen into milestonePhaseNums and so still flips
`roadmapUsesHyphenedIds`. Base does the same for that spelling, so preserving it
is what keeps the shape base-equivalent; excluding the token would have moved
answers versus base on malformed input. The comment at the qualified-set
declaration is corrected to claim only what is true — it keeps QUALIFIED IDS out
of that flag's input, not hyphens in general.

The oracles ship with it, and they are the five numbers, not the one: the parity
gate now asserts total_phases, completed_phases, total_plans, completed_plans AND
percent, on both derivations, on two fixture shapes (one milestone; two
milestones with stale prior-milestone directories on disk). The oracle is the
flat-legacy twin, built in the same test run and compared number for number,
plus exact literals so a shared wrong answer cannot pass.

The oracle SUBSTITUTION is itself pinned. The M-NN spelling of these shapes could
not serve, because buildStateFrontmatter's #2445 de-dup key captures only a
directory's leading integer and collapses `02-01-one` / `02-02-two` /
`02-03-three` to one — measured [3,0,1,0,0] against the flat-legacy twin's
[3,2,3,2,67], identically at base and before this fix, and structurally
unreachable from the bracket key space. That reasoning is only sound while it
stays true, so a characterization test holds the M-NN reading down on the two
numbers that do not depend on which directory wins the mtime race. Widen the
de-dup key and it fails, instead of quietly invalidating the changeset's
disclosure.

Also adds the call-site pin. The structural table pins transcription against the
selector; it cannot see a call site whose BASELINE ARGUMENT is wrong. Flipping
verify.cts's milestone-complete site to the wider baseline grants a
fires-on-every-repo check tolerance it has never had, and every behavioural test
still passed. The pin reads the shipped sources and asserts the mode at each of
the 14 sites, count-exact.

* test(#2761): pin the bracket read surfaces in the parity gate

This gate exists because #2043 fixed one bug across five hand-edited copies of a
rule and #2232 was the residual that survived, because a later reader could not
tell the copies were one rule. PR-2 adds two consumers, so they belong here.

Surface 7 — the heading read and the directory read must agree about WHICH phase
a `MM-<seg>` pair names, across the shared width corpus, and the bracket and
legacy spellings of one heading must yield the same token.

Surface 8 — the two bracket directory readers, in BOTH directions. Agreement on
ACCEPTED input was already pinned; agreement on REJECTED input is where they
actually diverged.

* chore(#2761): changeset

Disclosures for the PR body (deliberate, not defects):

- phase_id_convention is not a CONFIG_DEFAULTS key, so loadConfig drops it and
  cannot serve as the convention resolver however the file is federated. This PR
  ships its own workstream->root resolver; adding the key and its value enum is
  later-slice work.
- Convention matching is strictly === 'bracket'. A misspelled value reads as
  not-configured and the project keeps legacy behaviour silently.
- An UNPADDED bracket milestone (`[GSD.2]`) is malformed: it scopes nothing,
  bounds nothing, sections nothing, and is not a phase id. W005 on its
  directories is the surfacing signal.
- WIDTH UNIFICATION MOVED FOUR MERGED PR-1 EXPORT ANSWERS on non-canonical
  inputs, none of which toDir can emit and none of which had a bracket caller at
  base:
    isSentinelPhaseId('GSD.0-01',    'bracket')  true  -> false
    isSentinelPhaseId('GSD.0999-01', 'bracket')  true  -> false
    getMilestoneFromPhaseId('GSD.2-01',   'bracket')  'v2.0' -> null
    getMilestoneFromPhaseId('GSD.002-01', 'bracket')  'v2.0' -> null
  The canonical pad2 sentinel spelling `[GSD.00]` still tests true.
- FLAG TO MAINTAINER: docs/adr/612:132 reads "Sentinel behavior (0.x / 999.x ->
  milestone null) is preserved". After the unification that holds for the
  canonical `00` spelling only, not for a bare `[GSD.0]`. ADR wording is yours;
  flagging the tension rather than editing it.
- The bracket sentinel rule COMPOSES with the legacy one — a bracketed heading is
  a sentinel when its bracket milestone OR its token is reserved. Under bracket
  the state-side token rule is the full {0, 999} set so both derivations agree;
  the LEGACY path keeps its pre-existing 999-only rule, unchanged.
- validate consistency's legacy reading is untouched, including the pre-existing
  wart that `### Phase 999:` warns there while validate health suppresses it.
- find-phase still cannot resolve a bracket phase directory. phase-locator.cts is
  outside this PR's module set. Sibling PR #2559's matchPhaseDirs calls
  phaseTokenMatches without a convention, so whichever slice lands second must
  thread it through.
- Four of the five bracket readers scan raw ROADMAP content, so a bracket heading
  inside a fenced code block is read as a phase. Pre-existing for the legacy
  spelling; parity, not a new class.
- roadmapPhaseLookupSources gained no bracket source: nothing emits a
  milestone-qualified query into it yet.
- roadmap validate remains a separate, unfederated convention reader.
  Pre-existing and base-identical, but two verbs can disagree about the active
  convention on one project.
- _diskScanCache keys on cwd while the values it caches are now
  convention-dependent. Not reproducible through the CLI; pre-existing for the
  workstream dimension, widened here. Stated as inconclusive.
- A ROADMAP written in bracket form before config.json is switched reads as empty
  rather than mis-counted — the deliberate migration-window trade.
- THE READ AND WRITE PERCENTS STILL DIVERGE ON A MULTI-MILESTONE REPO, and that
  divergence is MIRRORED under bracket rather than closed. buildStateFrontmatter
  applies the milestone filter; cmdStateSync does its own fs.readdirSync and never
  calls it, so on a repo carrying prior-milestone directories the read path
  reports the SCOPED percent and the sync body reports the WHOLE-DISK one.
  Measured on the true base build (d04592de), flat-legacy spelling, 3 in-scope
  phases with 1 complete plus 2 stale prior-milestone dirs: `state json`
  [3,1,3,1,33], sync body 60%. The bracket twin of that repo now reads the same
  two numbers — 33 and 60. Scoping the sync counter would move every legacy
  repo's percent, which a bracket read-path PR must not do. The gate pins both
  sides, so the mirror cannot silently become a one-sided fix.
- THE PARITY ORACLE IS THE FLAT-LEGACY TWIN, NOT THE M-NN ONE, and that is a
  measurement finding rather than a preference. buildStateFrontmatter's #2445
  de-dup key captures only a directory's LEADING integer, so the M-NN dirs
  `02-01-one` / `02-02-two` / `02-03-three` all key to `2` and two of the three
  are dropped before they are ever counted: base reads [3,0,1,0,0] where the
  flat-legacy twin of the same repo reads [3,2,3,2,67]. Present identically at
  base and at HEAD, untouched here, and structurally unreachable from the bracket
  key space — `GSD.02-01-one` does not match that pattern at all, so every bracket
  directory keys to its own name. The source line already carries a
  `phase-id-owner:` sanction recording the divergence. Mirroring it under bracket
  would mean manufacturing a collision that cannot occur, so the gate compares
  against the flat-legacy spelling, which is uncontaminated. This paragraph is
  itself pinned: a characterization test holds the M-NN reading on the two
  numbers that do not depend on which directory wins the mtime race, so widening
  the de-dup key in a later slice fails the suite rather than silently making
  this disclosure false.
- THE `phaseTokenMatches` CALL-SITE CENSUS, stated so the remaining gaps are
  auditable rather than implied. 13 call sites outside the owner (phase-id.cts).
  THREE are three-argument: verify.cts:2229 (the W021 milestone-complete read,
  already was), roadmap.cts:436 (`roadmap analyze`'s directory lookup, threaded
  by this PR) and roadmap-parser.cts:792 (the disk-side milestone filter, added
  by this PR). The other TEN are two-argument and stay that way — phase.cts ×5
  (220, 277, 444, 585, 1547), phase-locator.cts:62, smart-entry.cts:243,
  init.cts:1414, milestone.cts:551 and verify.cts:2467. All ten are untouched by
  this PR and base-identical.
  One of them sits in a file this PR DOES edit, so it is named rather than left
  to a reader's grep: verify.cts:2467, `verify schema-drift <phase>`. Measured on
  a bracket repo across base / pre-fix branch / this HEAD, all three agree on all
  three argument forms — `verify schema-drift GSD.02-01` and `… 01` both report
  "Phase directory not found" on every build, and `… GSD.02-01-one` resolves on
  every build through the exact-directory-name fallback. So the user-visible
  shape of what stays broken is: a bracket phase is addressable there by full
  directory name only, exactly as at base. Threading the convention into a
  function this PR never touched, in the last round before ship, is the wrong
  trade; it is where the same one-argument fix goes next, alongside
  milestone.cts:551 and init.cts:1414.
- A BRACKET HEADING WHOSE TOKEN CARRIES A HYPHEN (`### [GSD.02] Phase 02-01:`,
  a mid-migration spelling) forms NO milestone-qualified key, and therefore
  scopes through the unqualified legacy path — base-equivalent ACCEPTANCE, which
  is the claim, and not a base-equivalent reading: `total_phases` on that shape
  moves 1 -> 2 for the same reason it moves on the canonical `### [GSD.02] 01:`
  spelling, because counting bracket headings is what this PR does. Such a token
  still flips `roadmapUsesHyphenedIds`, as it also does at base. The comment at
  the qualified-set declaration now claims only that narrower, true thing.

The `pr:` field carries the sub-issue number as a placeholder — it must be
updated to the real PR number when the PR is opened.

* chore(#2761): point the changeset at PR #2867

* test(#2761): fast-check properties for the convention-selection layer

CONTRIBUTING.md mandates a generative property test for parser/bijective-contract
changes; PR-2 shipped six example-based files and none. This adds the missing
layer, scoped to what PR-2 actually contracts — WHICH pattern each reader
compiles, decided by the resolved `phase_id_convention` — rather than restating
PR-1's grammar round-trip properties, which already live in
tests/adr-612-bracket-grammar.test.cjs.

Four properties: P1 an opted-in repo reads the ADR-canonical label-less bracket
heading/dir and a non-opted-in repo is byte-blind to the identical input; P2
every non-bracket convention agrees with the hand-transcribed BASE source over
generated content, including bracket-DOTTED legacy prose (`[RFC.2119] 5:`) that
must never be claimed as a phase; P3 nine per-field mutations are rejected and
the one case variation folds instead; P4 both sides of a phase comparison derive
the same key under the same convention.

Generators template every input from raw primitives — nothing is seeded through
renderPhaseId/toDir, the p2() tautology that made #2258 round 1's property test
structurally unable to find B1. Domain reaches past 99 into the 3+-digit branch
(round 2's numArb-capped-at-99 miss), forces sub-phases in at weight, and pins
both sentinel milestones.

Falsified against the COMPILED lib, not the source: five deliberate mutants
(gate never fires; gate always fires; milestone width widened to \d+; the #612
convention forwarding dropped from phaseKeyFromDir; extractPhaseToken's bracket
branch ungated) each fail the specific property that should catch them —
16/2, 16/2, 15/3, 17/1, 17/1 pass/fail — and the lib restores byte-identical.

An earlier draft of P2 held vacuously: its base regex omitted the markdown
furniture the selected one carried, so every realistic `### Phase NN:` line
matched neither side. The gate-always-fires mutant did not kill it. Both are now
compiled through one function, and that mutant kills P2.

* test(#2761): adversarial malformed bracket tokens across the tolerant readers

The existing boundary coverage stopped at shapes the emit grammar rejects
(unpadded `[GSD.3]`, wrong-case, `12A`). It never exercised a STRUCTURALLY
broken token — a non-numeric milestone, a bracket that never closes, a bracket
nested in another — which is the input a tolerant reader is most likely to
half-read, and the one the PR's own regex commentary is explicit about.

read-tolerance (roadmap heading scan + validate's dir and variant builders):
ten malformed headings, each asserted to be read as a phase by NO convention and
to give the opted-in repo the same answer as the legacy one; the corpus driven
through `roadmap analyze` end to end; malformed DIRECTORY names asserted
unrecognized and non-throwing on all four conventions; and the two variant
builders asserted to agree, since a widening that reaches only one splits
`validate consistency` from `validate health` (the #3242 Bug B shape).

coherence (verify.cts W021): the same six broken shapes asserted to raise no
W021 of their own AND not to re-scope the W021 that follows them — the G2
failure mode reached from a different shape, where a heading that is not a phase
but IS read as a section silently moves later warnings onto the wrong milestone.

Both files gain a pathological-input time bound. Nested quantifiers over a long
unclosed bracket are the classic ReDoS shape and two commits on next (#2828,
#2944) were CodeQL-flagged for exactly that, so the bound is asserted rather
than argued from reading the pattern. The probes themselves parse no regex.

* docs(#2761): document "bracket" as a phase_id_convention value

The row listed only `"milestone-prefixed"` and `null`, so after two shipped
slices (#2258 grammar, this PR's read path) the convention had no documented
enum value. CONFIGURATION.md is also a top-10 historical co-changer of both
src/verify.cts and src/state.cts and was absent from this PR.

The row states the boundary rather than the ambition: `"bracket"` changes the
READ path only, there is no migrator and no emit yet, and a project on any other
value compiles the patterns it compiled before. That keeps the docs honest for
the two releases before PR-3 and PR-4 land, instead of describing a convention a
user cannot yet migrate to.

* chore(#2761): retype the changeset Added, drop the docs-exempt marker

`Fixed` was wrong by CONTRIBUTING.md's own definition — a fix restores
documented behavior, and bracket read tolerance is the second slice of a
capability that did not exist before #2258. The type also carried a
`docs-exempt` marker, and `Fixed`/`Security` are exempt from the docs-required
lint, so the typing had the effect of routing around a gate this change should
pass. It now passes it: `lint-docs-required` returns ok_docs_updated on the
CONFIGURATION.md row added in the previous commit.

Body gains one sentence pointing at that row and restating that `"bracket"` is a
read-path opt-in until the migrator and write path land.

* test(#2761): pin the version-less bracket milestone scoping gap; narrow the claim

The changeset asserted that milestone scoping "recognises the ADR-canonical
`## [GSD.02] Foundation` heading and applies to the phase DIRECTORIES too." A
CLI probe on that exact heading form falsifies the second half: with no `vN.N`
in the milestone heading the directory side does not scope, and directories from
BOTH the prior and the later milestone are admitted. Measured 4 dirs counted
where the milestone declares 2.

Every bracket fixture in the suite writes `## [GSD.02] v2.0: …`, so nothing
covered the form the ADR actually specifies — and the state.cts doc comment
calls that version-less form canonical.

Mechanism, in extractCurrentMilestone: the bracket scope branch selects the
right currentSection, but `preambleCutoff` keys off a pattern requiring a
version or status emoji, so a version-less roadmap falls back to the current
milestone's own offset and every PRIOR milestone lands in the preamble — whose
phase-stripping regex only strips `Phase N:`-labelled headings, so bracket phase
headings survive it. Independently, `computeSectionEnd` accepts a boundary only
on a version/emoji heading, so the section runs to EOF and every LATER milestone
is swept in. Two sites, bidirectional.

Not fixed here: it changes milestone scoping, which is shared with the legacy
path. Five characterization tests pin today's reading plus a versioned CONTROL
proving the version string is the only difference, and the changeset sentence is
narrowed to what the code does. The DEFECT assertions are written to be
INVERTED by the fix, not deleted — that inversion is its regression proof.

* docs(#2761): re-anchor the branch's own cross-file line citations after the rebase

Three of this branch's code comments cite sibling call sites by line number, and
the rebase onto 178ec000 moved two of the three targets:

  roadmap-parser.cts  validate.cts:210 -> :218   (const g = capturing ? 1 : 0)
                      state.cts:1715   -> :1752  (const bg = … 'bracket' ? 1 : 0)
  roadmap.cts         verify.cts:2229  -> :2355  (phaseTokenMatches 3-arg form)

`state.cts:1715` had drifted 37 lines and now lands on the retirement skip, not
the capture-offset idiom the sentence is about — the citation read as evidence
for a claim the cited line does not support.

planning-workspace.cts's `config-loader.cts:618/:649` was checked and is still
correct; left alone.

Comment-only. Build, drift guard and the bracket suites re-run unchanged.

* fix(#2761): scope the version-less bracket milestone heading too (B1)

computeSectionEnd and the preambleCutoff scan in extractCurrentMilestone
(roadmap-parser.cts) only recognized a milestone boundary heading that
carried a vN.N token or a status emoji. The ADR-canonical bracket
heading (## [GSD.02] Foundation) carries neither, so on that shape
computeSectionEnd fell through to content.length (sweeping every LATER
milestone into scope) and preambleCutoff fell back to the current
milestone's own offset (leaking every PRIOR milestone's bracket phases
into the preamble, whose Phase-N: strip regex never matches them).

Under the bracket scope branch, both sites now also accept a
`#{1,2}\s+\[CODE.MM\]` boundary, built from phase-id.cts's BRACKET_ID_SRC
(single owner of the bracket-id grammar) rather than a re-typed literal.
`#{1,2}` is the deliberate discriminator: a bracket PHASE heading is
level 3 and shares the same `[CODE.MM]` prefix, so a `#{1,3}` boundary
would swallow it too. Reachable only when bracketScopeConvention ===
'bracket' was already resolved (i.e. the bracket scope branch actually
fired), so version-bearing/emoji headings and non-bracket conventions
take the exact pre-existing code path byte-identically — confirmed by
the full adr-612 suite staying green.

Inverts the four DEFECT assertions in the
"#612 PR-2 CHARACTERIZATION: a version-less bracket milestone does not
scope" describe block (tests/adr-612-bracket-phase-counting.test.cjs)
into their regression-proof form, per the block's own doc comment, and
reframes the describe title/comments accordingly. Corrects the
.changeset/2761-bracket-read-tolerance.md fragment, which described the
directory-side version-less gap as an open, un-closed bound.

* fix(#2761): thread sentinelPhases into validate health's W006 loop (B2)

cmdValidateHealth's W006 loop (src/verify.cts) destructured only
roadmapPhases from buildRoadmapPhaseVariants, not sentinelPhases —
unlike cmdValidateConsistency, which already skips sentinelPhases with
the identical guard a few hundred lines up. A heading-only bracket
icebox/pre-milestone entry ([GSD.999] / [GSD.00]) therefore gained a
false W006 "no directory on disk" from validate health while validate
consistency correctly stayed silent on the very same ROADMAP — the two
validators contradicting each other.

Threads sentinelPhases through and skips it before the existsOnDisk
check, mirroring the consistency guard exactly. Gated the same way
sentinelPhases already is (empty unless phase_id_convention is
'bracket'), so a legacy repo's W006 reading — including its own
pre-existing wart where a legacy `### Phase 999:` still warns on both
verbs — is untouched; confirmed by the existing "INHERITED WART,
unchanged" test staying green.

Adds the paired-agreement regression test (#612 PR-2 B2 describe block
in tests/adr-612-bracket-read-tolerance.test.cjs): a sentinel-only
bracket roadmap must produce no missing-directory warning from EITHER
validator, plus a CONTROL proving a real phase with no directory still
warns on both. Confirmed red (health false-W006) against the pre-fix
code before applying the fix.

Corrects the .changeset/2761-bracket-read-tolerance.md fragment, which
described the asymmetry as already closed and in the wrong direction
(it credited validate health with already staying silent, when health
was the one falsely warning).

* test(#2761): pin mixed-shape preamble cutoff and boundary heading levels

Closes two self-flagged coverage gaps in the B1 fix (commit 08d5b0c4)
ahead of adversarial review. No src change — all three new tests are
green against the code as committed.

1. earliest-of-either preambleCutoff comparison: only exercised where
   the version/emoji match and the bracket match happen to land on the
   same heading. Adds the mid-migration mixed shape (version-bearing
   PRIOR + version-less CURRENT) and asserts scoping outcomes (accepts
   booleans + total_phases), not internals.

2. `h.level <= 2` conjunct in computeSectionEnd: provably redundant
   whenever the selected milestone heading is level 2 (every existing
   fixture), since `h.level > level` alone already implies it there —
   a mutant deleting the conjunct would have survived every prior test
   in this file. Adds a level-3 CURRENT-heading fixture (with a real
   PRIOR milestone so the preamble side-channel can't independently
   rescue the truncated phases) that makes the conjunct's deletion
   test-visible, confirmed by hand-mutating a throwaway copy of the
   compiled output (never touching tracked src or the real build) and
   observing the assertion flip. Also pins a level-1 companion case
   (#{1,2} tolerance, not just level 2).

NOT included here: the other mixed-shape direction (version-less PRIOR
+ version-bearing CURRENT) turned out to be a genuine, currently-unfixed
gap — reported separately rather than silently patched or weakened, per
instruction not to touch src while a probe run is in flight.

* fix(#2761): engage bracket boundaries when the current milestone heading is version-bearing (B3, self-caught)

Found during round-2 self-verification of B1 (commit 08d5b0c4), while
closing the mixed-heading-shape coverage gaps flagged in my own review
notes. The B1 fix resolved `bracketScopeConvention` only inside the
`if (headingMatches.length === 0)` gate that also drives SELECTION's
own bracket fallback (which heading counts as "current"). That gate is
correct for selection, but `bracketScopeConvention` also feeds
computeSectionEnd's and preambleCutoff's boundary detection further
down — which accidentally inherited selection's gate instead of having
its own.

Trigger shape: the CURRENT milestone heading is itself version-bearing
(`## [GSD.02] v2.0: Current Milestone`), so the primary version-string
match succeeds immediately — headingMatches.length !== 0 from the very
first check — and the entire bracket-resolution branch was skipped. A
sibling milestone (PRIOR or LATER) that is version-less then got
neither the version/emoji boundary rule (it has none) nor the bracket
boundary rule (never resolved), reproducing the original #612 defect
(total_phases falling back to the whole-disk count) through a
structural shape B1's own fixtures never exercised — every one of them
is uniformly version-bearing or uniformly version-less across all
three milestones, never mixed with CURRENT specifically being the
version-bearing one.

Fix: resolve `bracketScopeConvention` unconditionally, decoupled from
`headingMatches.length`. SELECTION is deliberately left untouched — the
`if (headingMatches.length === 0 && bracketScopeConvention === 'bracket')`
fallback that picks which heading is "current" keeps its original gate
byte-for-byte (confirmed by diff: that line is unmodified). Only the
convention *resolution* moved out from behind it, so boundary detection
can consult it regardless of which branch selected the heading. The
extra `resolvePhaseIdConvention` call this now costs on every
invocation (previously paid only when the version match found nothing)
is the accepted cost: a non-bracket repo still resolves to something
other than 'bracket' (or null on a poisoned env, caught exactly as
before), so `bracketMilestoneHeadingRe` stays null and every downstream
branch is byte-identical to today — confirmed by the full adr-612 +
roadmap-parser + state + verify + health-validation suite staying green
(1260/1260) and the all-version-bearing/legacy fixtures showing no
behavior change.

TDD: tests/adr-612-bracket-phase-counting.test.cjs describe block
"#612 PR-2 B3: bracket boundaries engage even when CURRENT is
version-bearing but a sibling is not" — 4 tests, confirmed red against
pre-fix code (leak-in booleans true/true, total_phases 4) before this
change, green after.

* fix(#2761): reject same-milestone continuation headings as boundaries (B1)

Gate-2 adversarial review Blocker 1: the B1/B3 boundary fired on ANY
as the one currently selected — a version-less checklist/detail split
(`## [GSD.02] Foundation (Phase Details)`, or an ad-hoc continuation
heading) truncated the current milestone's own section instead of
being recognised as a continuation of it. The `(Phase Details)`
re-append only searches VERSION-STRING matches, so a version-less
continuation heading was cut out and never re-appended — a confidently
wrong, non-degraded phase count for a still-incomplete milestone
(repro8 case 1: 1/1/100 instead of 2/1/50; repro5: same, on a fully
version-less roadmap with no sibling milestones at all).

Introduces one shared helper, isBracketMilestoneBoundary(headingText,
level, selectedBracketId), used by both computeSectionEnd and the
preambleCutoff bracket scan, replacing the ungated `h.level <= 2 &&
bracketMilestoneHeadingRe.test(...)` inline check. `selectedBracketId`
(case-folded via phase-id.cts's foldBracketId, matching the branch's
own fold-before-identity convention) is derived from `selected[0]`,
which is the full matched heading line on BOTH selection paths
(version-string and bracket-fallback), so one extraction covers both.

Level cap stays at `level > 2` for now (temporary — ADR-612's content
discriminator replaces it in the next commit); same-milestone rejection
is the change this commit is scoped to.

DEVIATION from the reviewed plan, caught empirically: applying the
same-milestone rejection at the preambleCutoff site (as literally
specified) regressed an existing pin ("boundary heading level: a
level-1 CURRENT milestone heading also scopes correctly") and a
fenced-heading case (repro10 A3) — because preambleCutoff's job is
"where does the earliest milestone-shaped heading sit, scanning from
the TOP of the document," and the selected heading's own occurrence is
always a correct answer to that question regardless of same-id-ness;
rejecting it let the earliest-of-either comparison fall through to a
stray LATER heading instead. `selectedBracketId` is threaded through as
`null` at the preambleCutoff call site for this reason — bracket-shaped
(and, from the next commit, phase-tail) discrimination still applies
uniformly at both sites; only the same-milestone component is
call-site-specific, since it encodes a "keep scanning past this
heading" instruction with no counterpart in a top-of-document search.

Tests: new describe block "#612 PR-2 B1 round-2: a same-milestone
continuation heading is not a boundary" — RED-turned-GREEN fixtures for
repro8 case 1 and repro5, plus PINs for repro8 case 3 (trailing
different-id icebox still terminates) and repro10 A1 (all-version-
bearing + icebox + Phase Details stays exactly 2/1/50 — no double-count
from the same-milestone exclusion interacting with the pre-existing
detailsMatch re-append). syncedTotal()/syncedPercent() assertions
omitted from the repro10 A1 pin: that fixture carries dirs outside the
current milestone, which exposes the SEPARATE Major 1 defect
(cmdStateSync's body percent from an unfiltered disk scan) — asserted
once Major 1 is fixed, not here.

Full suite green (796/796 across the targeted adr-612 + roadmap-parser
+ state files); node scripts/lint-phase-id-drift.cjs clean; eslint
clean on both changed files.

* fix(#2761): bracket boundary discriminates by content, not heading level (B2)

Gate-2 adversarial review Blocker 2: three sites disagreed about which
heading levels are a bracket milestone. The selector
(roadmap-parser.cts's bracket-fallback SELECTION branch,
`^#{1,3}\s+\[CODE.MM\]`) and `isMilestoneBounded` (state.cts) both
admit level 1-3, but isBracketMilestoneBoundary's level cap only
admitted level 1-2 (`h.level <= 2`, from the B1 commit). A `###`-level
bracket milestone heading was therefore SELECTED and BOUNDED but never
TERMINATED: computeSectionEnd ran with level=3, a level-3 SIBLING
milestone survived the pre-existing `h.level > level` (not-deeper)
filter, failed the version/emoji test (version-less), then failed
`h.level <= 2` — falling through to `return content.length` and
sweeping the sibling milestone's own phases into the current one.
Reproduces trek-e's original #612 defect verbatim ("a safe degrade
became a confidently-wrong persisted number") on a heading level the
selector and bounding predicate both already admit (repro2 case C:
4/75% instead of 2/100%; mechanism confirmed directly via repro7 —
extractCurrentMilestone returned the whole 214-byte document).

ADR-612 Decision 1 (docs/adr/612-bracket-phase-id-convention.md:56)
specifies the discriminator as CONTENT, not level: "a phase heading is
a bracket followed by a digit-then-colon ([GSD.02] 05:); a milestone
heading is a bracket followed by a name." Replaces the `level > 2`
rejection with BRACKET_PHASE_TAIL_RE — built by interpolating
phase-id.cts's single-owner phaseHeadingPrefixSrcFor(ANY_BRACKET,
'bracket', false) plus the digit + optional-tag + colon tail every
phase-heading counter in this file already spells, not a re-typed
grammar — and widens the level check to a depth-sanity cap of 3
(mirroring the selector's own `#{1,3}` ceiling; NOT itself a
phase/milestone discriminator). Covers the dotted sub-phase heading
form (`[GSD.02] 05.03:`) via the same `[\w][\w.-]*` token, pinned by a
new fixture — the shape where a regex slip in the tail grammar would
hide.

preambleCutoff's own raw-scan regex is widened from `^(#{1,2})` to
`^(#{1,3})` in lockstep: the outer pattern's level ceiling must track
the helper's cap, or a level-3 PRIOR milestone heading is invisible to
that scan and its own phase heading leaks into the preamble
un-stripped (a real double-count this widening closes, verified
against repro2 case C directly).

The existing "boundary heading level: a level-3 CURRENT milestone
heading still scopes correctly" pin (3e562f12) now passes via a
DIFFERENT mechanism than before — its own neighbours are version-
bearing, so it previously passed via the version/emoji rule (the level
cap was never actually exercised by that fixture, per the round-2
review's own finding); with the content discriminator, the SAME
fixture's level-3 phase headings are now correctly excluded because
they are phase-tail-shaped, not because they are too deep. A
deliberate mechanism change, confirmed by re-running that test green
after this commit.

Also updates the "every selector call site declares the right
baseline" governance pin (adr-612-bracket-heading-selection.test.cjs):
BRACKET_PHASE_TAIL_RE is a new, legitimate ANY_BRACKET call site in
roadmap-parser.cts (always passing the literal 'bracket' convention,
since its only caller is already gated on bracketBoundaryActive) —
EXPECTED count bumped 1->2, with a matching BASE_SITES transcription
entry (identical src to every other ANY_BRACKET site, since the
function is pure).

Tests: new describe block "#612 PR-2 B2 round-2: the bracket boundary
is a CONTENT discriminator, not a level cap" — RED-turned-GREEN for
repro2 case C (exact total AND truthful percent, since
isMilestoneBounded already returns true at #{1,3}) and repro7's
mechanism, a PIN for the dotted sub-phase form, and a re-pin of repro8
case 3 (icebox) under the new mechanism.

Full suite green (907/907 across the targeted adr-612 + roadmap-parser
+ state + phase-id files); node scripts/lint-phase-id-drift.cjs clean;
eslint clean on all changed files.

* fix(#2761): fence-aware preamble cutoff on the bracket branch (Blocker 3)

Gate-2 adversarial review Blocker 3: preambleCutoff's bracket scan used
a raw content.match/matchAll — blind to fenced code blocks — while its
sibling computeSectionEnd (a few lines above it) already consumed
tokenizeHeadings(content), which strips fences. The two halves of one
boundary semantic disagreed about what a heading is.

A fenced markdown example in the preamble containing a bracket heading
(ADR-612's own docs do exactly this) was textually the earliest
`#{1,3} [CODE.MM]` match: preambleCutoff landed INSIDE the fence,
`preamble = content.slice(0, preambleCutoff)` ended with an unclosed
opener, and the unbalanced fence then blinded
getMilestonePhaseFilter's own tokenizeHeadings(scope) call — every
heading in the returned scope vanished, phaseCount degraded to 0, and
the pass-all filter admitted every directory on disk (repro11's
mechanism, confirmed directly: fence count 1/odd, tokenizeHeadings(scope)
-> only "Roadmap"). Regression vs round-1, which had no bracket pattern
to blind and so fell back to the correct heading (repro12 bracket row:
2/1/50 at round-1, 4/3/75 at HEAD).

Fixed by hoisting one tokenizeHeadings(content) call
(currentMilestoneHeadings) shared by computeSectionEnd and the
preambleCutoff scan, which now iterates that same fence-aware token
list instead of a raw regex. HeadingToken.text is already hash-stripped
and trimmed, so isBracketMilestoneBoundary needs no `^#{1,3}\s+`
re-derivation at this site (that spelling would not match h.text — a
note the round-2 review called out explicitly, confirmed while
porting). selectedBracketId stays `null` here, unchanged from the B1
commit's same-milestone-exclusion reasoning.

DISCLOSED, not fixed (explicitly out of scope per the round-2 review's
own minimal-fix note): the LEGACY (non-bracket) anyMilestonePattern
raw-match path shares the identical fence-blindness hazard and stays
byte-identical — a bracket repo whose preamble has a fenced
VERSION-BEARING heading still has the legacy raw-match win the
earliest-of-either min() (repro12's LEGACY control: 4/3/75, unchanged
across base/round-1/HEAD/this commit). Pinned here so a future reviewer
files this as a known, pre-existing gap rather than a new regression.

Tests: new describe block "#612 PR-2 Blocker 3 round-2: preambleCutoff
is fence-aware (bracket branch only)" — RED-turned-GREEN for repro12's
bracket row and repro11's mechanism (fence balance + non-degraded
phaseCount + correct per-directory admission), a PIN for repro12's
LEGACY control (the disclosed gap, explicitly unchanged), and a PIN for
repro10 A3 (a fenced heading INSIDE the current section must still not
terminate it).

Full suite green (1072/1072 across the targeted adr-612 + roadmap-
parser + state + phase-id + markdown-sectionizer files); node
scripts/lint-phase-id-drift.cjs clean; eslint clean.

* fix(#2761): scope cmdStateSync's disk scan by milestone under bracket (Major 1)

Gate-2 adversarial review Major 1: `state sync` wrote a Progress
PERCENT computed from an UNFILTERED whole-disk scan, beside the
milestone-scoped total_phases/completed_phases it writes into the same
STATE.md via the refreshed frontmatter (syncStateFrontmatter ->
buildStateFrontmatter, which has always applied getMilestonePhaseFilter
for the READ path). cmdStateSync's own `fs.readdirSync` chain (the
WRITE-path scan) never called the milestone filter at all, unlike
buildStateFrontmatter's identical-purpose scan. One command therefore
wrote two contradictory numbers into one file: on the ADR-canonical
version-less bracket fixture (4 dirs, 3 complete; asserted milestone =
2 phases, both complete), base wrote total_phases:2/completed_phases:2
(correct, from the READ derivation) alongside body Progress 75% (wrong
— from the unfiltered WRITE derivation; repro3).

Fixed by threading `getMilestonePhaseFilter(cwd)` through the same
`.filter()` chain buildStateFrontmatter already applies, gated on
`syncConvention === 'bracket'` (falling back to a pass-all predicate
otherwise) — so totalDiskPlans/totalDiskSummaries/diskCompletedPhases/
syncTotalPhases become milestone-scoped under bracket, byte-identical
under legacy.

DEVIATION (approved, stated plainly): an earlier phrasing of this fix
called for mirroring buildStateFrontmatter's filter UNCONDITIONALLY.
Implemented GATED instead — an unconditional filter would ALSO move
every LEGACY repo's persisted percent, since the milestone-scoping-vs-
whole-disk divergence this closes is engine-wide, not bracket-specific.
The gate keeps legacy byte-identical, which is the binding constraint:
this is a bracket read-path PR, not a legacy behavior change.

Nit 2 (informational, no code change): 10 calls to
extractCurrentMilestone on a legacy repo cost 10 config.json
existsSync + 10 readFileSync (0 before B3); accepted, unmemoized cost,
unaffected by this commit.

Also folds in two minors from the round-2 review:
- Corrects .changeset/2761-bracket-read-tolerance.md: the sibling-
  exclusion sentence now states it holds at any heading level 1-3 and
  across a milestone split over two headings (true again now that
  Blockers 1 and 2 are fixed); the percent sentence states plainly that
  `state sync`'s body percent is now milestone-scoped under bracket,
  and unaffected under legacy.
- Records the read/write scoping divergence at currentMilestoneRawRanges
  (src/roadmap-parser.cts) in a comment: it did not receive B1/B2's
  bracket boundary fixes, currently harmless (its only consumer falls
  back to whole-content mutation, and every mutation there is still
  Phase-labelled-only, not bracket-widened), but live the moment the
  write path is bracket-widened — flagged so a future PR closes it in
  lockstep with that work, not after.

Tests: 6 pre-existing tests in tests/adr-612-bracket-phase-counting.test.cjs
needed fixture updates, not logic changes — they used the default
single directory (`GSD.02-01-setup`, phase "01"), which the SENTINEL/
retirement/mixed-heading fixtures in those tests never declare as a
real phase (only 04/05/06/999/etc are declared). Before this fix,
cmdStateSync's unfiltered scan counted that off-roadmap directory
anyway; after this fix the milestone filter correctly excludes it,
which for several of these fixtures made `state sync` a no-op (the
computed 0% coincided with STATE.md's initial template default) and
broke `syncedTotal()`/`syncedPercent()`'s ability to observe anything.
Updated each to pass an EXPLICIT directory naming one of the fixture's
REAL declared phases, preserving each test's original numerator/
denominator intent. One test — "shape 2 WRITE" — was substantively
rewritten: it was a CHARACTERIZATION of the Major 1 bug itself ("the
DISCLOSED legacy gap, mirrored — not closed"), and now correctly pins
bracket closing to 33% (agrees with the read path) while legacy stays
at the disclosed 60% (unchanged, deliberately, per the gating decision
above).

Full suite green: `npm test` 1449/1449 (0 fail, 0 skipped, 0 todo,
single-shard "all" run — includes issue-2765-brace-expansion-lockfile
passing); `npm run lint:ci` clean (0 errors; 2 pre-existing timing-
assertion warnings in files this PR does not touch); node
scripts/lint-phase-id-drift.cjs clean; node scripts/changeset/lint.cjs
ok.

* fix(#2761): preambleCutoff identity is offset- and child-aware (round-3 Blocker 1)

Gate-2 round-3 re-verify Blocker 1 (NEW): the round-2 B1 deviation
(39c42a89) threaded `selectedBracketId` as the real value at
computeSectionEnd but as bare `null` at the preambleCutoff scan. The
deviation's rationale — "the selected heading's own occurrence is
always a correct earliest answer" — was right, but `null` disables the
same-milestone check for EVERY candidate, not just the selected one.
Any bracket-shaped heading earlier than the selected milestone was
accepted as a boundary regardless of identity: a same-id checklist/
overview heading preceding the version-bearing selected heading (cases
A, B — the version lands on the LATER half of a split, or a plain
overview heading with no "(Phase Details)" spelling), or a DIFFERENT-id
bracket-shaped PROSE heading with no children of its own sitting above
the current milestone's content (case D — `## [ADR.612] Heading
convention used by this roadmap`). In every case the region between
that false boundary and the real sectionStart was silently dropped —
a completed phase vanished and `state sync` persisted a confident 0%
where base and round-1 both correctly wrote 50%. Regression vs base
AND round-1 (not merely "under-fixed", per the round-3 review's own
severity note).

Fixed with two changes, both scoped to the preambleCutoff scan only
(computeSectionEnd already threads the real `selectedBracketId` and is
untouched):

(a) `h.offset === sectionStart` now bypasses BOTH the same-milestone
    check inside isBracketMilestoneBoundary (passing the REAL
    `selectedBracketId` for every other candidate) and the new child
    rule below — the selected heading's own position is definitionally
    the correct answer, so neither discriminator should run against it
    (rejecting it would mean rejecting the heading against ITSELF).
    Closes cases A and B — verified by the reviewer's own one-liner,
    reproduced here.

(b) New `bracketHeadingHasMatchingChild`: an otherwise-accepted
    candidate (bracket-shaped, not phase-tail-shaped, not the same id
    as the selected milestone) must ALSO have a next-strictly-deeper
    heading carrying its OWN bracket id to count as a boundary. This is
    what a genuine sibling milestone has (its own phase children share
    its bracket id — `## [GSD.01] Setup` / `### [GSD.01] 01: …`) and an
    unrelated bracket-shaped prose heading does not. A candidate with
    no such child at all (childless — e.g. an empty prior milestone, or
    one immediately followed by a same-or-shallower heading) degrades
    to NOT a boundary — over-inclusive, the safe direction: its own
    heading text stays in the preamble, contributing nothing to any
    phase count (not phase-shaped). Closes case D, which (a) alone does
    not — verified: without this rule, `[ADR.612]`'s prose heading is
    indistinguishable from a genuine prior sibling at this site.

As a side effect, also neutralizes Nit 2 (a colon-less `[GSD.02] 05`
heading spuriously terminating the preamble): a colon-less bracket
heading is not phase-tail-shaped so isBracketMilestoneBoundary alone
would accept it, but it is — precisely because it is malformed/
incomplete rather than a real milestone — childless, so the child rule
rejects it too. Pinned.

Known interaction with the fence-blind SELECTION path (disclosed by
the reviewer, not introduced here, tracked for the next commit): when
`sectionPattern` selects a FENCED version-bearing heading (an
extremely pathological shape — a fenced example whose text happens to
match STATE's asserted version), no token exists at `sectionStart`, so
the `h.offset === sectionStart` bypass never fires and the loop falls
through to the ordinary same-id / child-rule checks. This composes
with the round-3 Major 1 fix (next commit) rather than introducing a
new defect — SELECTION itself is untouched by any of this — but is
worth stating plainly rather than rediscovering.

Tests: new describe block "#612 PR-2 Blocker 1 round-3: preambleCutoff
identity is offset- and child-aware" — RED-turned-GREEN for cases A, B
(rv-attack1) and D (rv-attack1b) with syncedTotal()/syncedPercent()

for the colon-less Nit 2 shape, and the reviewer's rv-mech1 mechanism
re-run as a proper test (scope now equals the full input document,

* fix(#2761): fence-aware version/emoji half of preambleCutoff on the bracket branch (round-3 Major 1)

Gate-2 round-3 re-verify Major 1 (NEW): ff6bf0a8 (round-2 Blocker 3)
made the BRACKET half of preambleCutoff's "earliest milestone-shaped
heading" search fence-aware, but left the VERSION/emoji half a raw
`content.match` even on the bracket branch. A fenced VERSION-BEARING
example heading in a bracket repo's preamble (ADR-612's own docs
illustrate the LEGACY heading shape exactly this way, inside a fenced
authoring-guide block) was still textually the earliest match for that
raw regex, winning the min() and un-suppressing a wrong persisted 75%
that base correctly suppressed (rv-attack3c fixture C1: base
suppressed the percent entirely — `isMilestoneBounded` false — HEAD
wrote 75% where truth is 50%).

Fixed by deriving the version/emoji half from the SAME fence-aware
`currentMilestoneHeadings` token list as the bracket half, on the
bracket branch only — the exact `/^Phase\s+\S/i` / `/v\d+\.\d+|✅|📋|🚧/i`
pair `computeSectionEnd` already uses against `h.text`. The non-bracket
(legacy) path is untouched: it keeps the raw `content.match`, byte-
identical to before, including its own fence-blindness (repro12's
LEGACY control, pinned unchanged in the round-2 Blocker-3 test block —
not re-pinned here to avoid duplicating an already-covered assertion).

Not rated Blocker (per the review) because it is not a regression vs
round-1 and the fixture (a version-BEARING fenced example in a bracket
repo) is rarer than the already-fixed bracket-heading case; still
fixed now rather than disclosed, per this arc's own precedent (every
prior "disclose instead of fix" call in this PR has been overturned on
re-review).

Tests: new describe block "#612 PR-2 Major 1 round-3: preambleCutoff's
version/emoji half is fence-aware on the bracket branch" — RED-turned-
GREEN for case C1 (readTotal + syncedPercent, so the persisted 75% is
directly observed, not just the read-path total), PIN for case C2 (the
already-fixed fenced-bracket-heading shape, unchanged).

* chore(#2761): correct changeset claims + mark runtime-gated BASE_SITES row (round-3 minors)

Gate-2 round-3 re-verify Minor 2: three changeset sentences in
.changeset/2761-bracket-read-tolerance.md were overstated in a new
direction after round-2:

- The split-milestone claim ("across a milestone split over two
  headings") was true only when the version-bearing heading came
  FIRST (repro8 case 1); false when it came LATER (round-3 Blocker 1
  case A). Now restated to say plainly "with the version-bearing
  heading in EITHER position" — true again now that round-3's Blocker
  1 fix lands earlier in this range.
- The "counted from the phases... rather than from every directory on
  disk" claim was false on cases A/B/D (a strict subset of the
  milestone's own phases). Restated as "ALL of the phases... not a
  subset", and extended to state that an unrelated bracket-shaped
  heading with no phase children of its own (case D's `[ADR.612]`
  shape) does not truncate the milestone either — true now, not before.
- "Each widened read is SELECTED by the project's phase_id_convention"
  was literally false for BRACKET_PHASE_TAIL_RE, which is RUNTIME-gated
  (via its only caller, isBracketMilestoneBoundary, itself only
  consulted when bracketBoundaryActive) rather than selector-gated.
  Restated behaviourally: "every widened read ENGAGES only when the
  project's resolved phase_id_convention is bracket" — true for both
  gating mechanisms, so it no longer implies a selector call this site
  does not make.

Minor 1: the STRUCTURAL IDENTITY test's BASE_SITES row for
BRACKET_PHASE_TAIL_RE (added in the B2 commit) asserts a property of
`phaseHeadingPrefixSrcFor` — the function — not of the call site; it
would pass unchanged even if the site were deleted. Safety at that
specific site rests entirely on a runtime gate the test cannot see.
Added `runtimeGated: true` to the row and threaded it into the
generated test's own title (`… [runtime-gated, not selector-covered]`),
so the gating mechanism is visible in test OUTPUT, not only in a source
comment that could drift silently.

No production code changed. Targeted suite green (48/48 in the
affected file); `node scripts/changeset/lint.cjs` ok; eslint clean.

* fix(#2761): harden round-3 preamble cutoff — subtree child scan + level cap

Team-lead review of f87bba0e found two edges in the round-3 preamble-
cutoff code, both hardened here.

AMENDMENT 1 — bracketHeadingHasMatchingChild (2e06aef5) checked only
`headings[index + 1]`, the IMMEDIATE next heading, not the candidate's
whole subtree. A genuine prior sibling milestone whose section opens
with a non-bracket subsection before its first phase heading
(`## [GSD.01] Setup` / `### Notes` / `### [GSD.01] 01: Old`) was
therefore wrongly rejected as a boundary — its real phase heading sits
TWO headings deep, not one — leaking its entire section into the
preamble unstripped.

CONFIRMED RED, not merely theoretical (built and ran the fixture
against f87bba0e before touching the fix, per instruction): scope
membership DOES drive the disk-side filter on this shape.
`GSD.01-01-old`'s directory was wrongly admitted into the CURRENT
milestone's filter via the leaked heading's qualified key
(`GSD.01-01`) — 3/2/67% where truth is 2/1/50%.

Fixed by scanning the candidate's full SUBTREE: continue past a
non-matching deeper heading instead of returning false on the first
one; only a same-or-shallower heading actually closes the subtree and
yields "no match found". A candidate whose entire subtree closes with
no same-id hit (including a genuinely childless one) still degrades to
`false` — over-inclusive, safe, unchanged from before.

AMENDMENT 2 — c483552a ported the version/emoji half of preambleCutoff
to the token-based scan with no level cap; the raw
`content.match(anyMilestonePattern)` it replaced was anchored
`^#{1,3}\s+`. A level-4+ version-bearing heading in the preamble
(`#### v2.0 notes`) therefore won the scan on the bracket branch where
the raw pattern — and the legacy path, unaffected — ignores it
outright. Fixed with `if (h.level > 3) continue;`, mirroring the
depth-sanity cap isBracketMilestoneBoundary already applies to the
bracket half of this same scan.

Tests: new describe block "#612 PR-2 round-3 hardening: subtree child
scan + level cap on preambleCutoff" —
- RED-turned-GREEN for the Notes-intervening fixture: exact 2/1/50 (was
  3/2/67), plus the disk-filter observable (`GSD.01-01-old` now
  correctly excluded).
- PIN for the level-4 preamble heading: the scope now PRESERVES the
  heading's text (was silently dropped before this fix — harmless in
  this minimal fixture's total_phases specifically, since the dropped
  text carries no phase-shaped content, but a real correctness gap
  against the raw pattern's own ceiling) — asserted via scope content,
  not total_phases, since that number is invariant here either way.
- PIN for the LEGACY control on the same level-4 shape — unchanged,
  confirming the raw content.match path is untouched.

Re-verified the existing genuine-prior-sibling and childless-sibling
pins (round-3 Blocker 1 commit) still pass under the subtree scan —
both fixtures' outcomes are unchanged since their same-id hit (or its
absence) was already at the first deeper heading.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 942/942 pass (939 + 3 new). node scripts/lint-phase-id-drift.cjs

* fix(#2761): bracketHeadingHasMatchingChild requires a same-id PHASE child (round-4 Blocker 1)

Gate-2 round-4 re-verify Blocker 1 (NEW): the round-3 hardening's
subtree scan (fbfd0fca) proved SAME-ID-NESS but never asked whether
the matching child was PHASE-shaped. Case F1 re-opens round-3's case D
one heading later: `## [ADR.612] Heading convention` is followed by
its OWN sub-heading `### [ADR.612] Examples` — same bracket id as the
candidate, but MILESTONE-shaped (a name, no digit-then-colon), not a
phase. Same-id-ness alone satisfied the subtree scan and re-cut the
preamble at exactly the shape the round-3 hardening was written to
close.

Failing input: `## [ADR.612] Heading convention` / `### [ADR.612]
Examples` (prose) / `### [GSD.02] 01: One` (the current milestone's
own first phase, now unreachable) / `## [GSD.02] v2.0: Foundation` /
`### [GSD.02] 02: Two`. Truth 2/1/50. HEAD read 1/0/0, and `state sync`
reported "nothing to do" (exit 0, `{synced:true,changes:[]}`) because
its wrong 0% happened to equal the STATE.md seed — a half-done
milestone read as untouched with no write-path signal at all.

Fixed with the reviewer's one-conjunct addition: a same-id child only
counts if it is ALSO phase-tail-shaped (`BRACKET_PHASE_TAIL_RE`) — the
same single-owner discriminator `isBracketMilestoneBoundary` already
uses one level up for the identical distinction (phase vs milestone),
reused here rather than re-derived. This is exactly what the
changeset's own wording already claimed ("no phase children of its
own") — the code now matches the sentence rather than the other way
around.

Docstring updated at the function itself: the rule is "same-id PHASE
child", not "same-id child".

Tests: new describe block "#612 PR-2 round-4 Blocker 1: the same-id
child must be PHASE-shaped" — RED-turned-GREEN for F1 with
syncedTotal()/syncedPercent() (the persisted 0% — and the
report-nothing-to-do write-path silence — is the point), PINs for F11
(colon-less same-id child) and F11b (bullet-only phase list): both
correctly stay excluded either way, and the leak the phase-shape
requirement newly creates for these two shapes is INERT — a colon-less
heading forms no qualified key (getMilestonePhaseFilter's own
phase-heading pattern requires the colon too) and a bracket bullet
never matches the legacy-only BULLET_PHASE_LINE_PATTERN — confirmed
directly via getMilestonePhaseFilter, not merely inferred. Re-verified
the four existing child-rule pins (F2 subtree-closure, F3 deep-nested
same-id, F4 level-4 same-id, F5 childless-at-EOF) are unaffected by the
phase-shape requirement, since every one of them already used a
colon-bearing same-id child.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

-> 946/946 pass (942 + 4 new). Zero drift measured across the full F1-F12
corpus except F1 itself (F9/F10/F12 remain red, deferred to the

* fix(#2761): fence-aware phase counting, milestone bounding, and bracket-fallback selection (round-4 Major 1)

Gate-2 round-4 re-verify Major 1 (NEW): roadmapPhaseCount is a
fence-blind raw `.exec()` over the scope string, duplicated in TWO
independent copies (buildStateFrontmatter's read path, cmdStateSync's
write path). With the bracket alternative now compiled into it (#612),
a fenced EXAMPLE phase heading in the preamble inflates total_phases
and persists a wrong percent that base got right. Two further
fence-blind sites participate: isMilestoneBounded (a raw
`.test(roadmapRaw)`) and the bracket-fallback SELECTOR inside
extractCurrentMilestone (a raw `content.matchAll`, only reachable when
version-string selection finds nothing).

Failing inputs:
- F10 (clean isolate, version-bearing selection): a fenced
  `### [GSD.02] 05: Example phase` in the preamble inflates
  total_phases 2->3, persisting 33% where truth is 50%. LEGACY control
  on the same shape is correct on every build — not a pre-existing
  hazard being inherited, bracket-only.
- F9 (version-less selection): a fenced example carrying the project's
  OWN milestone id additionally confuses the bracket-fallback selector
  (the fenced heading gets SELECTED), compounding with the same
  fence-blind counter. base suppressed the percent; round-1 and HEAD
  both wrote 33%.
- F12 (isMilestoneBounded isolate): the ONLY `[GSD.02]` heading in the
  document is inside a fence, and the asserted milestone genuinely has
  no section at all — HEAD persisted 67% where base correctly
  suppressed the percent (the milestone is absent from the roadmap).

Fixed at the CONSUMER level, not the producer — extractCurrentMilestone's
returned scope string is deliberately UNCHANGED, since every other
consumer of that string needs its full content fidelity and legacy
identity forbids touching the shared string (this branch's own
precedent, ff6bf0a8/c483552a, was producer-level; here the ruling is
consumer-level because the string is shared far more broadly than the
two round-3 fixes' narrower producer edits):

(a) New `countRoadmapPhaseHeadings` (src/state.cts, immediately above
    extractRetiredPhaseNumbers) — ONE shared implementation for both
    call sites, replacing two independently-maintained copies. BRACKET
    convention counts via `tokenizeHeadings(scope)` at levels 2-4,
    testing each heading's hash-stripped text directly — fence-aware by
    construction, since tokenizeHeadings never produces a token for a
    fenced line. LEGACY convention keeps the exact pre-existing raw
    `.exec()` loop, byte-for-byte. A pre-existing, deliberately
    PRESERVED asymmetry between the two original call sites — the read
    path always excluded a bare `/^999\b/` token, the write path never
    did — is threaded through as an explicit
    `includeUnconditional999Check` parameter per call site, so sharing
    the implementation does not silently unify (and thereby move)
    either total.
(b) isMilestoneBounded's bracket branch now scans
    `tokenizeHeadings(roadmapRaw)` for a matching heading (level <= 3)
    instead of a raw regex test. Legacy version-string branch untouched.
(c) The bracket-fallback SELECTOR now builds its candidate set from
    `tokenizeHeadings(content)` instead of `content.matchAll`,
    reconstructing a match-shaped array so every downstream consumer of
    `headingMatches` sees the identical shape the raw-regex path always
    produced. This is the ONE site in this entire arc where SELECTION
    itself changes — selection SEMANTICS are otherwise unchanged (same
    pattern, same first-match-wins by document order); only the
    candidate set is now fence-aware. Pinned that unfenced selection is
    byte-identical.

Zero drift measured across the full historical corpus (repro2-13,
rv-attack1/1b/3c, rv-mech1, rv2-amend1/2, and F1-F11b) except the three
target fixtures.

Tests: new describe block "#612 PR-2 round-4 Major 1: four fence-blind
sites on the bracket path" — RED-turned-GREEN for F10 (with
syncedTotal()/syncedPercent()) and F9 (both layers), PINs for F10's
LEGACY control and F10c (non-phase-shaped fence, unaffected either
way), RED-turned-GREEN for F12 (asserts the percent KEY is absent from
`state json`'s output and that `state sync`'s body stays at its
unmodified seed — the persisted-suppression signal, not merely a
total_phases number), and an explicit PIN that unfenced bracket-fallback
selection (first real milestone-shaped heading wins, no fences
involved) is unaffected.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* chore(#2761): correct docstring overstatement + stale consumer-count sentence (round-4 minors)

Gate-2 round-4 re-verify Minor 1 + Nit 1. No production code changed.

Minor 1: bracketHeadingHasMatchingChild's own docstring said a
rejected (no-same-id-PHASE-child) candidate's degrade "contributes
nothing to any phase count" — true of the candidate's OWN heading
text, but not of its SUBTREE, which is what actually stays in the
preamble. F7 (`## [GSD.01] Setup` / `### [GSD.07] 01: Foreign`) shows
a DIFFERENT-id bracket PHASE heading inside a rejected candidate's
subtree DOES form a qualified key and CAN admit a foreign directory —
3/2/67%, stable across base, round-1 and HEAD (base via its own
pass-all degrade). Not a regression, still the declared over-inclusive
/ never-under-inclusive safe direction — the comment now says that,
with F7's numbers cited, at the call site that actually decides
`isBoundary` (roadmap-parser.cts's preambleCutoff loop) rather than
only at the helper's own definition.

Minor 2 (changeset) — VERIFIED, no wording change needed: re-ran F1,
F9, F10, F12 at this HEAD. The "no phase children of its own... does
not truncate it either" sentence (naming the `[ADR.612]` shape
directly) is now literally true — F1 reads 2/1/50. The "counted from
ALL of the phases... not a subset" sentence is now true on every
measured shape — F1/F9/F10 all read 2/1/50, F12 correctly suppresses
the percent. No carve-out for F9/F10 is needed since round-4 Major 1
(3be5c412) closes both; per the fix-round instruction to "only carve
out anything genuinely left," nothing is.

Nit 1: tests/adr-612-bracket-heading-selection.test.cjs's runtimeGated
row claimed `BRACKET_HEADING_INTRO_RE` has "no other consumers" — true
when round-3's f87bba0e wrote it, stale since 2e06aef5 (round-3's own
earlier commit) had already added two more uses inside
bracketHeadingHasMatchingChild. Corrected to state the true count
(three consumers) and re-confirm the conclusion is unaffected: all
three are still nested inside the same bracketBoundaryActive runtime
gate, and BRACKET_HEADING_INTRO_RE is built from BRACKET_ID_SRC, not
phaseHeadingPrefixSrcFor, so it was never a selector site regardless of
consumer count.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): restore the bracketId guard in countRoadmapPhaseHeadings (round-5 Blocker 1)

Gate-2 round-5 re-verify Blocker 1 (NEW, introduced by 3be5c412): the
merge that created the shared countRoadmapPhaseHeadings helper dropped
the `bracketId && ` guard both original inline loops carried before
calling isSentinelPhaseId. Every other isSentinelPhaseId call site in
src/ (roadmap-parser.cts, roadmap.cts, validate.cts x2, verify.cts)
keeps the guard; state.cts's shared counter was the only one of seven
without it.

When the phase-heading-intro grammar's LEGACY alternative matches (a
`### Phase 00:` heading in a `phase_id_convention: "bracket"` repo —
the mid-migration shape this PR exists for), the bracket capture group
is `undefined`, so the unguarded call became
`isSentinelPhaseId("undefined-00", 'bracket')` — measured TRUE, so
phase 00 (and 000, 0a, 0.5, 999.1 — any token whose splice with the
literal string "undefined" happens to fall in a sentinel range) was
silently dropped from the denominator. `getMilestonePhaseFilter` (which
still carries its own guard) counts the phase and admits its directory
regardless, so the filter and the counter disagree — a half-done
milestone reads as 100% complete, persisted.

One-line fix, restoring the guard every sibling call site already has:

    if (bracketId && isSentinelPhaseId(`${bracketId}-${token}`, 'bracket')) continue;

Line count: `git diff --stat src/state.cts` -> 1 file changed, 1

* fix(#2761): extractRetiredPhaseNumbers is fence-aware on the bracket path (round-5 Major 1)

Gate-2 round-5 re-verify Major 1 (NEW) — a FIFTH fence-blind site on
the bracket path, missed by 3be5c412's own enumeration of "four".
extractRetiredPhaseNumbers' line scan (`scope.split(/\r?\n/)`) has no
fence awareness. This PR compiles the bracket alternative into
`introSrc` ("the retirement filter has to widen with the counter it
protects" — the function's own pre-existing comment), so a FENCED
authoring EXAMPLE showing the #1514 retirement gesture in bracket
spelling is now indistinguishable from a real one: it retires a
genuine phase, shrinking the denominator and persisting a confident
100% where base correctly read 50%.

Fixed with the SAME consumer-level ruling this arc has used at every
other fence-blind site, reusing markdown-sectionizer's existing
exported `stripFencedCode` rather than hand-rolling a second fence
parser (single-owner rule) — retirement lines are BULLETS, not
headings, so `tokenizeHeadings` doesn't serve here; `stripFencedCode`
is the general-purpose fence stripper the tokenizer itself is built on.
Gated on `convention === 'bracket'`; the LEGACY line scan stays the raw
`scope` string, byte-identical — its own fenced-example hazard is
pre-existing (wrong at base too) and out of scope.

Line count: `git diff --stat src/state.cts` -> 1 file changed, 9
insertions(+), 2 deletions(-) — one import added, four lines inside
the function (a comment + the `scanScope` computation + the changed
`.split()` call).

Tests: new describe block "#612 PR-2 round-5 Major 1:
extractRetiredPhaseNumbers is fence-aware on the bracket path" —
RED-turned-GREEN for G2 (fenced example in the preamble) and G2b (the
same example placed INSIDE the milestone section, ruling out a
preamble-scoping artifact — the site itself was fence-blind wherever
the fence sits), PIN for the LEGACY control (unchanged, pre-existing,
out of scope — base is wrong on this shape too).

Also folds in the "four fence-blind sites" correction: 3be5c412's
commit message and any restatement of it should read FIVE going
forward; this commit's own message states the count correctly.

* fix(#2761): state sync's counter excludes the bracket 999 icebox token (round-5 Major 2)

Gate-2 round-5 re-verify Major 2 (NEW) — `includeUnconditional999Check`
left `state json` and `state sync` reporting different totals for one
bracket repo. Under bracket, READING-B puts the sentinel in the
bracket, so `isSentinelPhaseId("GSD.02-999", 'bracket')` is false —
the `/^999\b/` TOKEN rule is the only thing excluding a
`### [GSD.02] 999:` icebox heading, and it ran on the read path
(buildStateFrontmatter, `true`) and on getMilestonePhaseFilter
(unconditional), but not on cmdStateSync's own counter (`false`). One
`state sync` call could leave a single STATE.md with its own
frontmatter (percent 50, from the read-path re-sync inside
writeStateMd) and body (percent 33, from the write-path counter that
alone still counted the icebox heading) disagreeing — falsifying this
PR's own stated invariant that sharing countRoadmapPhaseHeadings made
"the two counters must see the same phases" structural.

Functional change is one argument, exactly as specified: the write
call site now passes `syncConvention === 'bracket'` instead of the
literal `false`. `syncConvention === 'bracket'` is `false` for every
non-bracket value, so the LEGACY path resolves to the exact same
`false` it always did — this file's own pre-existing, deliberately-
unchanged read/write divergence on that path is untouched. The READ
site (`:1860`) is NOT touched — its historical behaviour applied
`/^999\b/` to legacy and bracket alike, so changing it would move
legacy READ totals, exactly the class of mistake this arc's own
Blocker 1 (this round) was.

Line count: the functional change is ONE argument
(`false` -> `syncConvention === 'bracket'`); the surrounding comment
was rewritten because the previous one asserted the now-superseded
behaviour ("preserving this file's pre-existing... divergence... a
bare 999 token is not excluded here") and leaving it would mislead the
next reader — not a structural change.

Tests: new describe block "#612 PR-2 round-5 Major 2: state sync
excludes the bracket 999 icebox token like the read path" —
RED-turned-GREEN for G1, asserting `state sync`'s body percent equals
`state json`'s own percent (both 50, not 33 vs 50), PIN for G1's
legacy control (33 vs 50 unchanged, deliberately).

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 962/962 pass (960 + 2 new). node scripts/lint-phase-id-drift.cjs
clean; eslint clean.

* chore(#2761): restore indent parity at the two line-start-anchored bracket-heading reconstructions (round-5 Minor 1)

`HeadingToken.offset` (tokenizeHeadings) is the LINE-START character offset,
not necessarily the `#` character's own offset — a ≤3-space-indented ATX
heading has both. Two round-4 reconstructions built on tokenizeHeadings
inherited this gap and accepted indented headings their raw, line-start-
anchored predecessors (`^#{1,3}\s+\[...`) never matched:

  1. roadmap-parser.cts's bracket-fallback SELECTOR (extractCurrentMilestone,
     ~line 377) — an indented, version-less `[GSD.02]` milestone heading
     could be reconstructed into headingMatches, then mis-parsed downstream
     (selectedBracketId null, level fallback to 1), leaking a SIBLING
     milestone's phases into the counted scope (G6: HEAD read 3/2/67 instead
     of 2/1/50 — a real phase heading's own directory belonging to the NEXT
     milestone got counted).

  2. state.cts's isMilestoneBounded (~line 1571) — the same gap let an
     indented-only `[GSD.02]`-shaped heading wrongly bound a milestone
     absent from the roadmap, un-suppressing a percent that should stay
     suppressed (mirrors round-4's F12 fenced-only case, but via indentation
     instead of a fence).

Fix: one added conjunct per site — `content[h.offset] === '#'` (source-named
`roadmapRaw` in state.cts) — filtering to tokens whose LINE-START offset IS
the `#` character, i.e. exactly the set the raw line-start-anchored regex
would ever have matched. Restores byte-for-byte raw parity; no other logic
in either function changes. computeSectionEnd and the preamble version/
emoji-token scan are untouched, as instructed — they consumed tokenizeHeadings
output before this arc and are out of scope here.

Also corrects roadmap-parser.cts's now-provably-false docstring claim that
`h.offset` is unconditionally "the same `#`-character coordinate space
`content.match().index` used" — true only for the survivors of the new
filter, not for every token tokenizeHeadings produces.

Line count: the FUNCTIONAL change is exactly 2 lines (one added `&&` conjunct
per call site — `git diff --stat` on the two source files shows 20
insertions/7 deletions, but only those 2 lines change behavior; the rest is
docstring/comment rationale, per this round's "state the line count" ask).

TDD: both fixtures verified RED at HEAD before this commit, GREEN after,
via /tmp/pr612rev/rv5-attack.cjs G6 and a locally-authored isMilestoneBounded-
isolating probe (G6 alone doesn't distinguish the two sites — its unindented
phase headings already satisfy isMilestoneBounded's loose prefix regex
either way, so a second, indentation-only fixture was needed to prove that
site's fix is not a no-op; verified by temporarily reverting just that one
conjunct, confirming 100%-wrongly-bounded RED, then restoring it, confirming
suppressed-percent GREEN).

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (G6): indented version-less bracket milestone heading — 2/1/50, not
    the pinned-before-fix 3/2/67.
  - PIN (G6c unindented control): identical document, no indent — 2/1/50
    unaffected on every build.
  - RED (isMilestoneBounded site, indented-ONLY): mirrors round-4's F12
    shape (fenced-ONLY → indented-ONLY) — percent stays suppressed instead
    of the pinned-before-fix wrongly-bounded 100%.

Full G1-G10 (rv5-attack.cjs) + G2b/G3c/G3d/G6c (rv5b.cjs) re-verified
zero-drift against TRUTH after this change. Targeted suite (adr-612-*,
roadmap-parser, state, verify): 962 -> 965 (+3), 0 fail.

* chore(#2761): changeset discloses counting-set narrowing + correct stale consumer-count sentence (round-5 minors)

FIX 5 (Minor 2): .changeset/2761-bracket-read-tolerance.md did not disclose
that bracket phase-heading counting is narrower than the raw-regex
predecessor in two ways the review's G4/G5 fixtures surfaced: a level-5
heading (`##### [GSD.02] 05: ...`) is no longer counted (the counter's
tokenizeHeadings scan caps at level 4, matching the selector/isMilestoneBounded
ceiling), and a space-less heading (`###[GSD.02] 05: ...`) is no longer
counted (CommonMark requires ≥1 space/tab after the hashes, which
tokenizeHeadings correctly enforces and the old raw regex did not). Both
G4 and G5 moved from round-1's wrong (inflated) values back to base's
original values as an incidental side effect of routing through
tokenizeHeadings — never a deliberate feature of this PR, and previously
undocumented. One clause added to the existing run-on paragraph; no other
wording in the changeset touched.

FIX 6 (Nit 1): tests/adr-612-bracket-heading-selection.test.cjs:76 —
`BRACKET_PHASE_TAIL_RE` has TWO consumers as of round-4's 65d257ce
(isBracketMilestoneBoundary's own use, plus bracketHeadingHasMatchingChild's
same-id-PHASE-child conjunct), not the "no other consumers" the comment
claimed. Same correction pattern round-4 already applied to this row's
BRACKET_HEADING_INTRO_RE neighbor (that sentence's own staleness was fixed
in 4d7184b8): note the true consumer count, confirm both stay nested inside
the same bracketBoundaryActive runtime gate (verified at
src/roadmap-parser.cts:178 and :250, both reached only through the
`if (bracketBoundaryActive)` block starting at :529), and record which
commit and which fix introduced the drift. Comment-only; no assertion
logic changed.

Line count: 2 files, 8 insertions / 2 deletions total — one added clause
in the changeset (1 line changed) and one comment block replacing the
single stale line in the test file (6 comment lines replacing 1).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 965/965 pass (comment/prose-only diffs, no test count change).
`node scripts/changeset/lint.cjs` and `npx eslint` on the touched files both
clean.

* fix(#2761): restore the bracketId guard on the bracket-only /^0\b/ sibling rule (round-6 Blocker 1)

Round-5's Blocker 1 was `isSentinelPhaseId("undefined-00")` — the merge
that introduced the shared counter dropped the `bracketId &&` guard on the
sentinel check. This is the identical failure one line further down, in the
sibling rule this PR itself added: when the phase-heading grammar's LEGACY
alternative matches (`### Phase 0:` in a `phase_id_convention: "bracket"`
repo — the mid-migration shape this PR exists for), `bracketId` is
`undefined`, and the unguarded `/^0\b/` fires on the bare token anyway.
Neither the LEGACY branch of this same function nor
`getMilestonePhaseFilter` has a `/^0\b/` rule at all, so the filter counts
the phase and admits its completed directory while the counter refuses to
count its heading — a milestone with an unstarted phase 02 persists as a
confident 100%.

`/^0\b/` matches `0` and `0.5` (word boundary before the `.`) but not `00`
(no boundary between the two zeros), which is exactly why round-5's G3/G3d
fixtures (`### Phase 00:`) never tripped this one — same defect class,
different token spelling.

Fix: one word, mirroring the guard round 5 restored two lines above —
`if (/^0\b/.test(token)) continue;` -> `if (bracketId && /^0\b/.test(token)) continue;`.

Expected and intentional side effect: `roadmap analyze` and `state json`
now disagree again on this bracket-repo shape (analyze phase_count=2, json
total_phases=3) — exactly as they already do under the legacy convention
today (verified via /tmp/pr612rev/rv6c.cjs on both conventions). That is
the counter regaining agreement with `getMilestonePhaseFilter` (the tighter
constraint — it is what actually decides `completed_phases`), not a new
break; the counter/filter disagreement is what was wrong.

Out of scope, deliberately NOT fixed here (Minor 1, disclosed via a PIN
test only): the bracket-SPELLED `### [GSD.02] 0:` shape has the same
counter/filter disagreement, but reads 2/2/100 on base too — never closed
by any build in this arc, so it is a pre-existing gap rather than a
regression this commit could introduce.

Line count: src/state.cts is exactly 1 insertion / 1 deletion (one word,
`bracketId && ` prepended to the existing condition).

TDD: T0 (`Phase 0:`) and T05 (`Phase 0.5:`) verified RED at HEAD before this
commit (json 2/2/100, sync body 100%) via /tmp/pr612rev/rv6b.cjs, GREEN
after (3/2/67 on both derivations, matching TRUTH). Zero-drift verified by
diffing the FULL corpus (rv5-attack, rv5b, rv4-attack, rv-attack1,
rv-attack1b, rv-attack3c, rv-mech1, rv2-amend1, rv2-amend2, rv6-attack
H1-H19, rv6b) between a pre-fix and post-fix build: the only differing
lines in the entire diff are T0, T05, and H14 — the three target fixtures.

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (T0) + PIN (T0L legacy control)
  - RED (T05) + PIN (T05L legacy control)
  - PIN (B0, bracket-spelled `0` — base-parity characterization, Minor 1,
    not fixed this round)
  Round-5's own G3 test (`### Phase 00:`) already serves as the T00 pin —
  `/^0\b/` never matched `00`, so it is unaffected and untouched.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 965 -> 970 (+5),
0 fail. `lint-phase-id-drift.cjs` and `npx eslint` on touched files clean.

* chore(#2761): changeset re-attributes the phase-count level cap + discloses the bare-0 carve-out; correct two stale test comments (round-6 Minor 1 + Nits)

FIX 2 (Minor 1 — disclosure only, NOT a code fix): the bracket-SPELLED
`### [GSD.02] 0:` / `0.5:` shape has the same counter/filter disagreement
round-6's Blocker fixed for the legacy spelling, but it reads 2/2/100 on
BASE too — never closed by any build in this arc, so it is a pre-existing
gap rather than a regression this round could introduce. Two changes:

  - Pinned as a base-parity characterization: new PIN test (B0) in
    04b5a95f's describe block asserting the exact unchanged value with a
    comment stating why it's deliberately not touched.
  - .changeset/2761-bracket-read-tolerance.md: one qualifying clause added
    to the "counted from ALL of the phases … not a subset" sentence — a
    bare `0`/`0.x` phase token (however spelled) keeps `roadmap analyze`'s
    own pre-existing sentinel reading under bracket too, so it stays
    excluded from these counts. Carried over, not newly introduced by this
    PR — `roadmap analyze` has always read it this way.

FIX 3(a) — same changeset paragraph misattributed the phase counter's
2-4 level cap to "the milestone-boundary machinery in this PR" (the
selector, `isMilestoneBounded`, the preamble scan) — that machinery caps
at `###` (level ≤3), not 2-4. The 2-4 cap belongs to
`getMilestonePhaseFilter`'s own phase scan. Re-pointed the attribution;
the paragraph's earlier, correct ≤3 claim (selector/isMilestoneBounded)
is untouched.

FIX 3(b) — tests/adr-612-bracket-heading-selection.test.cjs:76-82 (added by
1395bd89, round-5's own Nit-1 correction) claimed both
`BRACKET_PHASE_TAIL_RE` consumers are reached "only through the
`if (bracketBoundaryActive)` block starting at :529". Verified at HEAD:
`bracketHeadingHasMatchingChild` is (only caller :593, inside that block).
`isBracketMilestoneBoundary` is not — it has two callers, an inline
`bracketBoundaryActive &&` conjunct at `:473` (inside `computeSectionEnd`)
and the `:529` block at `:567` — the very fact this row's own earlier
"exactly two callers" paragraph already stated correctly. Corrected the
mechanism claim; the CONCLUSION (every consumer is still gated on the same
flag) is unchanged, exactly as round-5's own Nit-1 fix left round-4's
conclusion unchanged when it corrected the consumer count.

FIX 3(c) — tests/adr-612-bracket-phase-counting.test.cjs:2311,2340 still
said "four fence-blind sites" after round-5 (357ba671) added a fifth
(the retirement scan) in its own block below. Reworded both the section
comment and the `describe()` label to read as historical scoping of
round-4's own fix ("the four sites known at round 4 … a fifth was found at
round 5, see its own block below") rather than a live exhaustive claim.

Line count: 3 files, changeset 1/1, heading-selection test 17/8,
phase-counting test 6/2 (comment/prose-only; B0's own PIN test landed in
04b5a95f alongside T0/T05 since it was investigated as part of that same
Blocker's defect class, not in this commit — noted here for the record).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 970/970 (comment/prose-only diffs, no test count change).
`npx eslint` and `node scripts/changeset/lint.cjs` both clean.

* fix(#2761): W021's bracket remediation hint stops pointing at a command that hard-errors (round-7 Minor 2)

`checkBracketCoherence`'s W021 (added by 94abf5df) attached the fix hint
`Run \`gsd-tools roadmap upgrade --convention bracket\` to migrate
(dry-run by default)` to every bracket-convention W021 — both sub-checks
(`missing-bracket` and `mismatch`) share the single `addIssue` call at
src/verify.cts:2255-2256. But `roadmap-command-router.cts:204` throws
unconditionally for any `--convention` value other than
`milestone-prefixed`:

  $ gsd-tools roadmap upgrade --convention bracket
  Error: Only --convention milestone-prefixed is supported

This contradicts the PR's own two disclosures: the changeset ("`bracket`
is a READ-path opt-in until the migrator and write path land") and
docs/CONFIGURATION.md:188 ("There is no bracket migrator and no bracket
emit yet"). Reachability is the exact mid-migration repo this PR targets —
any bracket project with one un-migrated heading gets an unfollowable
instruction on every `validate health`.

Fix: one string. Replaced the hint with what a user can actually do today —
manually align the heading's bracket milestone to its section — and named
the tracked future landing (#612 PR-3) instead of a command that errors.
The milestone-prefixed sibling hint at src/verify.cts:2240 (a different,
already-functional convention/command pair — verified against
roadmap-command-router.cts:65) is untouched.

Line count: src/verify.cts is exactly 1 insertion / 1 deletion (one string
literal).

No test in the suite previously asserted this string's content
(`grep -rn "upgrade --convention bracket" tests/` was empty), so the
unfollowable hint shipped unpinned — `lint-fix-has-regression-test.cjs`
would not have caught a string-only change without a new test. Added one:
asserts the fix string both (a) does not match `--convention bracket`
(the specific pinned-before-this-fix hazard) and (b) equals the new string
exactly, covering the invariant a future edit must not re-break: no
unsupported `--convention` value named in remediation text users are
expected to run verbatim.

Verified end-to-end (not just unit-level) via /tmp/pr612rev/rv7f.cjs: the
W021 issue's `fix` field now reads the new string; `gsd-tools roadmap
upgrade --convention bracket` (and its --dry-run variant) still correctly
hard-error — that command remains unsupported, only the hint text changed.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 970 -> 971 (+1),
0 fail. `lint-phase-id-drift.cjs` clean; `npx eslint` on touched files:
0 errors (1 pre-existing unrelated no-elapsed-assertion warning, same file,
same line this arc's prior rounds already disclosed).

* chore(#2761): correct the bare-0 changeset disclosure + disclose W021's second sub-check (round-7 Minor 1 + Nit 1)

FIX 1 (Minor 1) — round-6's bare-0 changeset clause (1395bd89) was wrong in
three falsifiable ways:

  (a) Its own illustration (`### Phase 0:`) is exactly the LEGACY spelling
      04b5a95f made COUNTED. The residual exclusion after that fix applies
      only to the BRACKET-spelled token (`### [GSD.02] 0:`) — the clause
      named the wrong shape as its example.
  (b) "excluded from these counts" over-scoped the carve-out. The phase-0
      directory is admitted into `completed_phases`/`total_plans` in BOTH
      spellings (measured: B0 at HEAD has `completed_phases=2`,
      `accepts {"GSD.02-0-bootstrap":true}`). The exclusion that survives
      lives in `total_phases`/`phase_count` (heading counting) only.
  (c) The pre-existing "so `roadmap analyze` and `state json` report the
      same number" sentence (present since before this arc's bracket work)
      is now false for the bare-0 LEGACY-spelled shape: 04b5a95f's own
      commit message discloses this exact re-divergence as expected —
      `roadmap analyze` phase_count=2 vs `state json` total_phases=3 on T0
      — matching the disagreement legacy already carries today. The
      changeset still asserted unconditional agreement.

Rewrote both sentences: dropped the `### Phase 0:` example, scoped the
carve-out to `total_phases`/`phase_count`, named the bracket-spelled token
as the one that keeps analyze's sentinel reading, stated plainly that the
legacy-spelled form in a bracket repo IS counted (the mid-migration guard),
and qualified the "report the same number" claim to the `999` token, with
the bare-0 legacy-spelled shape named as the one exception and why.

FIX 3 (Nit 1) — `checkBracketCoherence` has always had two sub-checks
(its own docstring: "Two sub-checks, both surfaced as W021") but both the
changeset and docs/CONFIGURATION.md:188 described only the `mismatch`
sub-check. The `missing-bracket` sub-check — which fires on every
legacy-spelled heading in a bracket repo, the noisier of the two on a
mid-migration project — was undisclosed in both places. One clause added
to each.

Line count: 2 files, 1 line changed each (both are single-paragraph/
single-row files; git diff --stat reports 1/1 per file though several
distinct clauses were edited within that one line each).

Verified: `node scripts/changeset/lint.cjs` clean. Targeted suite
(adr-612-*, roadmap-parser, state, verify) unchanged at 971/971
(prose-only diffs, no test count change, no code touched).

* chore(#2761): resolvePhaseIdConvention's docstring no longer claims loadConfig drops the key

Upstream #2997 (aa7697fe, landed in `next` during this PR's final
verification) added `phase_id_convention: get('phase_id_convention') ?? null`
to `_baseConfig` in config-loader.cts — `loadConfig` now surfaces
`phase_id_convention` in its resolved config. This function's docstring
gave "loadConfig merges against CONFIG_DEFAULTS and drops keys it does not
know, and `phase_id_convention` is not among them" as the reason for
reading config.json directly instead of calling `loadConfig(cwd)`. That
rationale is now stale against live `next`.

Corrected the comment to state the two reasons that actually survive #2997:

  1. The workstream->root federation this function performs is a standalone
     resolution run against a GIVEN cwd, not necessarily the same base a
     `loadConfig(cwd)` call elsewhere in the codebase would federate from.
  2. Convention-ENUM validation is still #612 PR-4 work — this function
     returns the raw string unvalidated, exactly as the now-surfaced
     resolved key would.

Noted that #2997 surfacing the key makes consuming it from resolved config
(instead of re-reading config.json here) a natural PR-4 consolidation —
not this PR's scope. The "cycles were never the obstacle" close and every
other paragraph in the docstring (federation rationale, SCOPE note) are
untouched; they still hold.

Comment-only — no code behavior changed. This worktree's own history does
not contain aa7697fe (git merge-base --is-ancestor confirms neither branch
is an ancestor of the other; not rebasing per instruction), so this is a
textual correction against a documented external fact, not a functional
sync with upstream.

* fix(#2761): resolve phase_id_convention against the caller's workstream

`resolvePhaseIdConvention` took no workstream, so it resolved from
`planningDir(cwd)` — which falls back to `GSD_WORKSTREAM` only when its `ws`
argument is `undefined`. Every caller that passes a workstream by ARGUMENT
(they cannot set the env var per iteration) therefore read the convention from
the ROOT config while reading that workstream's ROADMAP.

Two reproduced consequences:

- A workstream that explicitly declares its own `phase_id_convention` had it
  ignored. Flipping ONLY the root config between bracket and milestone-prefixed
  changed which milestone that workstream extracted.
- `--workstream foo` and `GSD_WORKSTREAM=foo` disagreed on the same repo: the
  arg form fell through to the root config, the env form did not.

`resolvePhaseIdConvention(cwd, ws?)` now forwards `ws` to `planningDir`, and
both roadmap-parser call sites pass theirs — `extractCurrentMilestoneScoped`
(which already reads STATE from `planningDir(cwd, ws)`) and
`getMilestonePhaseFilter`'s lazy branch. `undefined` keeps the env fallback, so
convention-less call sites are byte-identical; `null` still means "explicitly no
workstream". The `undefined` vs `null` discriminator on `phaseIdConvention` is
untouched — only the base the `undefined` branch resolves FROM moves.

workstream-inventory's two sites (`countRoadmapPhases`, `inspectWorkstream`)
passed a literal `null` where they meant `undefined`, pinning every workstream
to the legacy grammar. On a bracket workstream whose milestone declares 3
phases that returned phaseCount 0 and fell back to the on-disk directory count;
it now returns 3. A non-bracket workstream is unchanged (legacy control pinned).

The workstream -> root federation is preserved: a workstream that declares no
convention still inherits the root, as config-loader does. That inheritance is
pinned so the fix cannot be over-applied into isolation.

* fix(#2761): classify missing phase details per occurrence, not per token

Under READING-B a phase's sentinel status lives in the BRACKET, so
`[GSD.999] 01` and `[GSD.02] 01` share a token and are not the same phase.
Both sides of the missing-detail check were keyed by the bare token anyway, and
both produced false negatives in `missing_phase_details`:

- The checklist scan built a token -> bracket-id Map, FIRST-WINS. Of two entries
  sharing a token, whichever the author wrote first classified both. With
  `- [ ] **[GSD.999] 01: Icebox**` above `- [ ] **[GSD.02] 01: ...**` the real
  phase inherited the icebox's sentinel verdict and vanished from the report;
  swapping the two bullets — same document, same phases — reported it. Pinned
  with a test asserting BOTH orders.

- The detail set was `new Set(phases.map(p => p.number))`, also token-keyed, so
  `[GSD.02] 01`'s heading marked token `01` present and satisfied
  `[GSD.03] 01`, which has no heading anywhere. Order-independent, same class.

Both sides now key on an occurrence key: the owner's `bracketQualifiedKey`
(fold- and padding-insensitive, so `[gsd.2] 01` and `[GSD.02] 01` are one
phase), falling back to a fold-normalized composite for the two shapes that
grammar refuses — a token carrying its own hyphen, which splices to an id whose
trailing segment the qualified-key grammar truncates (the hazard
`getMilestonePhaseFilter` guards with its own `!token.includes('-')`), and any
id it does not accept. With no bracket id the key IS the bare token, so the
legacy path keeps its exact keys and dedupe order.

The emitted value is unchanged — `missing_phase_details` stays an array of bare
tokens, matching `phases[].number`. Only the classification moved to the
qualified key, so two brackets' `01` both missing report `01` once instead of
one silently covering for the other.

* test(#2761): replace the two wall-clock ReDoS assertions with algorithmic bounds

Both guards asserted elapsed wall-clock time — `Date.now()` against a 20s
ceiling in the coherence suite, `process.hrtime.bigint()` against 1s in the
read-tolerance suite. Those measure the host machine rather than the SUT and
flake on a loaded CI runner (RULESET.TESTS.no-timing-assertion). Per
RULESET.TESTS.delete-bad-tests they are REPLACED, not skipped, and the
behavioral property each one guarded is preserved.

The property is "the widened bracket patterns do not backtrack
catastrophically", which is a claim about growth, so it is now stated by
scaling the input instead of by timing it:

- validate health runs the pathological unclosed bracket at 4,000 and 16,000
  characters and must return the same correct result (no W021) at both.
- The four reader entry points run five ReDoS shapes at 5,000 and 20,000 and
  must name exactly the phases each shape should name at each size, with the
  variant cardinality unchanged across the two.

Catastrophic backtracking is superlinear, so a regression cannot complete the
4x leg under any ceiling, while a bounded matcher is indifferent to the
scaling. The one attack that is well-formed-but-oversized now pins its reading
precisely (`['1'.repeat(n)]`) rather than being lumped in with the malformed
ones. A positive control asserts the readers still extract a well-formed
bracket heading, so "names no phase" cannot pass by the readers being inert.

`{ timeout }` is a hang backstop, not an assertion: it turns a runaway into a
deterministic failure instead of a suite that never returns.

* fix(#2761): give the bracket grammar one owner and teach the drift guard to see it

The bracket milestone-intro grammar was re-typed verbatim in three readers —
roadmap-parser's bracket-fallback selector, state's `isMilestoneBounded` and
verify's `checkBracketCoherence` — which is exactly what #2761's own gate
forbids ("no token literal outside src/phase-id.cts"). `check:phase-id-drift`
reported clean the whole time: its detector only ever knew the phase-NUMBER
token grammar, so the bracket class `[A-Z][A-Z0-9_]*` was invisible to it.

Ownership. `src/phase-id.cts` now exports the class as
`BRACKET_PROJECT_CODE_SRC` and the intro in the two shapes its readers need:
`bracketMilestoneIntroSrcFor(milestone)` (pinned to one milestone) and
`BRACKET_MILESTONE_INTRO_CAPTURING_SRC` (milestone captured). The pinned
builder owns the pad2 spelling rule too — "canonical spelling only, not `0*N`"
was previously restated in prose beside each copy, a convention two files had
to keep agreeing on by hand. `BRACKET_ID_SRC`, `BRACKET_ID_PREFIX_RE` and
`BRACKET_QUALIFIED_KEY_RE` now compose the class rather than re-spelling it.
All three call sites consume the owner; the regex sources are byte-identical to
what they spelled, asserted against hand transcriptions of the pre-fix lines.

Guard. `scripts/lint-phase-id-drift.cjs` gains a bracket rule
(`findBracketGrammarDrift`), wired into `scanRepo` and tagged `kind`. It
deliberately does NOT copy the token rule's `line.includes(CANON_REF)` escape:
that escape is line-level, and verify's copy referenced the owner for the
MILESTONE field on the same line as the re-typed PROJECT-CODE class — so a
bracket rule with that escape would have kept passing on the very site under
review. Partial ownership is the drift; only a dedicated `// phase-id-owner:`
comment suppresses it.

Proof, end to end: planting the shipped verify.cts literal back into src/ makes
`npm run check:phase-id-drift` exit 1 naming `[bracket] src/verify.cts:1475`;
restoring it returns the gate to ok.

Tests. phase-id-drift-guard carries all three shipped literals as negative
fixtures, the same-line-owner-reference case, the case-widened evasion variant,
the sanction rules, and a temp-tree scan proving the rule is wired into
scanRepo rather than merely exported. continuation-grammar-parity drives the
pinned and capturing shapes over a 12-entry corpus and requires the same
verdict from both plus the same captured milestone — widening either alone
fails there.

* test(#2761): drop the out-of-scope source-grep exemption from the selector pin

The baseline-selector pin in tests/adr-612-bracket-heading-selection.test.cjs
read `src/*.cts` with readFileSync and regex, claiming the no-source-grep
escape with a source-text-is-the-product reason. CONTEXT.md's documented scope
(RULESET.TESTS.no-source-grep.exemption) reserves that escape for tests whose
subject is a runtime CONTRACT FILE — STATE.md, config.toml, hooks.json, agent
.md — and `src/*.cts` is none of those.

It was also broader than it looked: eslint-rules/no-source-grep.cjs matches the
marker in ANY comment in the file, so one block's claim disarmed the rule for
the whole ~700-line suite.

The pin itself is worth keeping — the BASELINE ARGUMENT at each call site is a
fact no behavioural test can recover (flipping verify's milestone-complete site
from LABEL_ONLY to ANY_BRACKET grants a tolerance it has never had, and every
behavioural test still passes), so pinning it does require reading the authored
source. That reading moved to `scripts/lint-phase-id-drift.cjs` — the seam's
own guard, where source scanning is sanctioned (`warn` scope) and already
happens for the grammar rules — as `countSelectorBaselines` /
`scanSelectorBaselines`, which return a structured census. The test asserts on
the returned data and touches no file text.

CONTEXT.md is unchanged: the exemption scope was not widened to fit the test.
No marker remains in the suite, so the rule is live across all of it again, and
eslint passes with the escape removed rather than relocated. A floor assertion
pins that the census actually found the five consumers, so the "no other file
consumes the selector unpinned" check cannot pass on an empty scan.

* docs(#2761): rewrite the changeset as a lead + deltas instead of one paragraph

The fragment was a single ~6,400-character paragraph that opened on internal
mechanics, buried the user-visible change, and named an internal test path
(tests/adr-612-bracket-phase-counting.test.cjs) that means nothing to a reader
of the CHANGELOG.

It now leads with what a user sees — bracket-style phase IDs are recognized on
the read path across roadmap, validate, verify and state — followed by compact
bullets for the behavioral deltas, the opt-in caveat, and the upstream
consequences. Both merge-added disclosures are kept: the #3185 legacy-sentinel
Phase-0 delta with the reason the bracket counter keeps the narrower rule, and
the enumerator's convention-argument default flip with the four newly-scoped
read surfaces and the note that archival and milestone-completion paths are
unchanged. Two deltas from this review round are stated as their own bullets:
per-occurrence classification in `missing_phase_details`, and workstream-scoped
convention resolution including the workstream-rollup count change.

The internal test path is gone and the body is down to ~3,850 characters. The
bullets render as sub-bullets under the CHANGELOG entry and the `(#NNNN)`
suffix still lands on a trailing paragraph rather than mid-list.
`npm run lint:changeset` passes.

* test(#2761): use helpers.cleanup in the drift-guard temp-tree test

`local/no-raw-rmsync-in-tests` rejects a bare `fs.rmSync` in tests — the shared
helper carries the Windows-EBUSY retry budget. The temp-tree scan added with
M3's guard coverage test used the raw call.

* docs(#2761): correct the occurrenceKey comment on qualified-key normalization

The comment claimed `bracketQualifiedKey` is "fold- and padding-insensitive, so
`[gsd.2] 01` and `[GSD.02] 01` are one phase". The fold half is right; the
padding half is not. `BRACKET_MILESTONE_NUMERIC_SRC` is `(?:[1-9]\d{2,}|\d{2})`,
so `bracketQualifiedKey('GSD.2-01', 'bracket')` returns null and that input
takes the composite fallback instead.

No behavior change — the two key spaces use different separators and cannot
collide — but the claim was checkable and wrong. Restated: the owner case-folds,
and padding-tolerance is not a property it has or needs, because each accepted
milestone has exactly one canonical spelling and `[GSD.2]` is malformed rather
than an alternate spelling of `[GSD.02]`.

* ci(#2761): give the coverage-gate job the heap floor the shard jobs already have

The gate's report steps parse ~2.5GB of merged raw V8 dumps in one
process at the runner's implicit ~4GB ceiling, so pass/fail comes down
to GC timing (run 31338081337 OOM'd; next passes the same volume at
28s). Deterministic locally: crashes at --max-old-space-size=4096,
completes in 11s at 8192. PR shard data is within 0.15% of green next
runs — the load is pre-existing, only the ceiling was missing. #2952
set 6144 on the shard-collection step; the gate job was missed.

* Revert "ci(#2761): give the coverage-gate job the heap floor the shard jobs already have"

This reverts commit 03c74a97c911e9ddc53675aded9c9bbb89f14cd1.

* fix(#2761): thread the resolved convention into cmdStateValidate's phase-directory lookup

#3208 replaced cmdStateValidate's `startsWith` prefix test with the canonical
`phaseKeyFromDir(...) === selectedPhaseKey` comparison. That is the right
surface, and it is why the lookup now needs the resolved `phase_id_convention`,
which the rewrite does not pass.

`phaseKeyFromDir` deliberately refuses to read a bracket directory without an
explicit signal (ADR-2121: a bracket dir is string-indistinguishable from the
legacy letter-prefixed-decimal family), so un-threaded it returns the whole dir
name as the key — `GSD.02-05-real-work` -> `GSD.02-5-REAL-WORK` — while the
STATE side is the bare `05` that `parsePhaseFromProse` yields. Both sides of one
comparison derived under different conventions is #2562's defect class, and this
file's other three `phaseKeyFromDir` call sites already thread against it.

Observable: a bracket repo whose phase directory plainly exists reported
`valid: false` and "no phase directory matches phase 05", and the drift scan
(plan-count mismatch, verification status) never ran. The pre-#3208 `startsWith`
missed the same directory but skipped silently, so this is a visible-failure
regression on bracket repos, not a new miss.

Non-bracket conventions are byte-identical by construction: `extractPhaseToken`
branches only on `=== 'bracket'`, so null / 'milestone-prefixed' / unresolvable
compile the same path as the un-threaded call. The flat-legacy twin assertion
pins that.

* docs(#2761): note the cmdStateValidate convention threading in the changeset fragment

The fragment described the bracket read path as of the pre-merge branch. 504c64ff
added a shipped behaviour change — `state validate` now resolves bracket phase
directories — that the fragment did not mention, so the rendered changelog would
have under-described what ships.

Body text only; `type` and `pr` are untouched.

* test(#2761): invert the inherited-wart characterization — #3225 fixed it upstream

Required by the merge of next @ 86101ee6; test-only, no src delta.

This branch disclosed rather than fixed a pre-existing upstream wart: on a
LEGACY repo, `### Phase 999:` warned from `validate consistency` while
`validate health` suppressed it — the two verbs contradicting each other.
The case was pinned as a characterization test ("INHERITED WART, unchanged")
precisely so it would INVERT if upstream ever closed it, rather than rot
silently.

ae7dc529 (#3225) closed it, by adding the `isSentinelPhaseId` guard to this
very loop. So the assertion inverted on the merge — as designed. Flipped to
assert the FIXED behaviour rather than deleted: it is the negative-space
proof that this branch's `sentinelPhases` guard never had to grow a legacy
reading of its own, and it reds if a future conflict resolution keeps our
guard while dropping upstream's.

Added a scope control alongside it (a legacy NON-sentinel `### Phase 09:`
with no directory still warns), so deleting the loop outright cannot pass.

Union proven load-bearing in BOTH directions against the merged tree —
neither guard subsumes the other:
  - drop `isSentinelPhaseId(p)` (ours only) -> 1 red, exactly this case.
    Note upstream's own #3225 tests stay GREEN there: they cover the
    disk-side loops (sentinel dir on disk) and the gap-numbering filter,
    not the ROADMAP-side loop. This case is that site's only coverage,
    which is the second reason to keep it rather than delete it.
  - drop `sentinelPhases.has(p)` (upstream only) -> 4 red bracket suites
    (icebox-not-missing, health/consistency agreement, occurrence-aware
    suppression, checklist-index suppression).

tests/adr-612-bracket-read-tolerance.test.cjs 79 -> 80, all green.

* test(#2761): pin the three re-homed W006/W007 reads the merge left unfalsifiable

#3309/#3310 deleted the helpers this PR threaded (collectDiskPhases,
collectDiskPhaseEntries, collectArchivedPhaseDirNames,
forEachArchivedPhaseToken) and rebuilt their reads inside
src/planning-snapshot.cts + src/health-diagnostic-rules/*.cts. The convention
threading moved with them in the merge commit — but a mutation sweep over the
re-homed sites found three where reverting the convention argument changed real
CLI output and NOT ONE existing test went red. The pre-migration sites were
covered indirectly, through helpers that no longer exist, so the coverage did
not survive the relocation even though the behaviour did.

Each case is pinned at the CLI with its flat-legacy twin as the byte-identity
control, plus a non-vacuity control in the opposite direction:

  archivedPhaseTokens      revert -> "Phase 05 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for a phase whose only directory is
                                     under .planning/milestones/v1.0-phases/
  roadmapPhaseCheckboxes   revert -> "Phase 09 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for an unstarted `- [ ]` phase
  W007's extractPhaseToken revert -> "Phase GSD.02-77-orphan exists on disk"
  (roadmap-disk-consistency)         instead of "Phase 77 exists on disk"

Red/green: each single-line revert reds exactly its own case and nothing else;
every legacy control stays green in all three runs.

NOT pinned, and disclosed as droppable rather than given an unfalsifiable test:
buildValidPhaseSet's extractPhaseToken(dir, convention) in W002. That rule
unions disk tokens with roadmapDeclaredPhases and archivedPhaseTokens, and any
STATE.md reference a bracket disk token would rescue is already rescued by the
ROADMAP half — probed directly, the argument makes no observable difference. It
is threaded because it restores collectDiskPhases(planBase, convention)'s
derivation exactly, not because a test needs it.

Test-only; revertable independently of the merge commit.

* test(#2761): pin the two reads the #3165 extraction left unfalsifiable

DROPPABLE, offered as such. Test-only; the merge commit is correct without it.

#3428's extraction gave `collectAnalyzePhases` TWO call sites — the scoped
milestone window and the truncated-window recovery path. The merge threads
`convention` into both and swaps `detailKeys` with `phases` across the recovery.
Neither of those was falsifiable by the suite as it stood:

  - passing a NULL convention at the FALLBACK site, with the scoped site still
    threaded, is green across all 518 tests of the bracket, roadmap and
    milestone-window files. Every pre-existing bracket assertion reaches the
    enrichment through the scoped window, so none of them can observe the
    fallback's reading at all;
  - dropping `detailKeys = fallbackScan.detailKeys;` — the line this merge
    authored — is likewise green, because no fixture that reaches the recovery
    path carries a checklist bullet, so `missing_phase_details` is `null`
    either way.

That is the same hole class lap 3 closed in 9914359c: an argument whose revert
changes real CLI output with zero reds.

Pinned at the CLI on the shape that reaches the fallback on a bracket repo — a
MID-MIGRATION ROADMAP: bracketed ACTIVE milestone, its phase-detail sections
and checklist bullets sitting after an intervening CLOSED legacy milestone (so
the window closes over prose only), plus one legacy `### Phase N:` section of
its own. Six tests:

  - a NON-VACUITY control that removes the phase directories, so #3428's own
    precondition fails and the result is the empty one the recovery exists to
    replace — this is what proves the rest read the FALLBACK's output rather
    than the scoped scan's;
  - the directory assertion (`disk_status`/`plan_count`/`summary_count` for
    canonical `{CODE}.{MM}-{PP}-slug` dirs) + a flat-legacy twin asserting
    byte-equal shape, and that the twin is the right answer rather than a
    shared wrong one;
  - `missing_phase_details: null` for phases the recovery just found, and its
    companion direction — a bullet with no heading anywhere is STILL reported,
    so a fix that merely suppressed the report does not pass;
  - a non-bracket repo taking the same path unaffected.

Red/green, each mutation reverted afterwards:
  - fallback call site -> `null` convention: exactly 2 reds, both directory
    assertions in this block; 307 other tests green, including upstream's own
    #3428 tests in tests/milestone-window-single-owner.test.cjs.
  - `detailKeys` swap deleted: exactly 2 reds, both `missing_phase_details`
    assertions; 414 other tests green.
  - `matchPhaseDirs` 3rd argument dropped (the lap-2 site): 4 reds — the 2
    already on record plus this block's 2, which is the point: one seam, now
    reached by two paths.

DISCLOSED IN THE TEST BODY WITH MEASURED OUTPUT, not fixed: `hasPhaseEntries`
(src/roadmap-parser.cts) is convention-blind, so on a PURE-bracket ROADMAP the
window classifies COMPLETE and #3428's recovery is gated off entirely. That
document returns `{"scope":"complete","phase_count":0,"next_phase":null,
"phases":[]}` — the "genuinely empty milestone" answer, the indistinguishability
#3184 introduced `scope` to remove — where the flat-legacy twin returns
`{"scope":"truncated","phase_count":2,...}`. Widening it changes the value of an
upstream-owned output field on bracket repos, so it is a behaviour slice (the
PR-2.5/PR-4 convention-less-readers question), not a merge-round change. The
mid-migration shape pinned here is the reachable half.

* fix(#2761): mirror the bracket terminator in the milestone-scope write guard

parser's terminator vocabulary — "a level 1-3 heading that is not a Phase
heading and carries a milestone signal". On this branch that vocabulary is
convention-SELECTED: `computeBracketSectionEnd` adds `isBracketMilestoneBoundary`
as a terminator arm, and the ADR-canonical `## [GSD.09] Hidden` carries NO
vN.N token, NO ✅/📋/🚧/🔄 marker, and not the word "Milestone". Left
unmirrored, the guard accepted exactly the description it exists to reject.

NOT a defect on clean next — a bracket heading terminates nothing there. The
branch widens the terminator set, so the branch owns the mirror.

MEASURED at the CLI seam before the fix (bracket fixture, one milestone,
one phase):

  $ gsd-tools phase add $'Sneaky\n## [GSD.09] Hidden'   -> exit 0, written
  $ gsd-tools phase add 'Innocent follow up'            -> exit 0, written
  $ gsd-tools roadmap milestone-scope
    { "scope": "complete", "phases": ["01","1"], "phase_count": 2 }
  $ grep '^### Phase' .planning/ROADMAP.md
    ### Phase 1: Sneaky
    ### Phase 2: Innocent follow up      <- in the document, out of the window

After the fix the first add exits 1, ROADMAP.md is byte-unchanged and no
phase directory is created. The legacy twin (same text, no
`phase_id_convention`) still exits 0 — opt-in only, base behaviour preserved.

SHAPE
- `findMilestoneScopeHeadingLines(text, convention)` — REQUIRED, the same
  tripwire `scanMilestonePhaseIds` carries in the merge commit and for the
  sharper reason: a blind call here fails OPEN (the guard quietly ACCEPTS a
  window-narrowing description), so a future call site must fail to COMPILE.
  Census is one caller, which pays nothing for it. A non-bracket value takes
  the pre-existing path byte-identically. The bracket arm routes through
  `isBracketMilestoneBoundary`, the same single-owner phase-vs-milestone
  discriminator `computeBracketSectionEnd` consults; no second bracket-heading
  grammar is spelled here.
- `selectedBracketId` is deliberately `null`, so the same-milestone
  CONTINUATION exemption never fires and a value naming the ACTIVE milestone
  is flagged too. That is this predicate's third stated conservatism and
  rests on its own existing argument: which milestone is active is a property
  of the document at write time, not of the text being validated, and
  over-rejecting is one-directional.
- `assertDescriptionPreservesMilestoneScope` takes `cwd` and resolves through
  the branch's tolerant try/catch — this guard runs BEFORE `loadConfig` and
  before the ROADMAP existence check, so an unresolvable convention must
  degrade to the legacy vocabulary, never turn a rejection into a crash.
- The error's marker list gains the bracket form only when the project is on
  the bracket convention.

RED/GREEN
- Revert the bracket arm -> 2 reds (phase add; insert + add-batch), the
  non-bracket control and both no-false-positive cases stay green.
- Revert the probe threading in the merge commit -> 1 red (the probe case).
- 6 new cases in the #3262 file, each with a non-bracket or
  no-false-positive control: fenced bracket milestone heading and bracket
  PHASE heading are both non-violations.

Droppable: revert this commit and the merge stands on its own; the branch
then ships the gap as a disclosure instead of a fix.

* docs(changeset): narrow the enumerator claim to the directory set — per-entry rendering in progress/stats/init-manager is display-slice scope

Round-7 review confirmed 3 of the 4 surfaces named by the closing claim
parse each directory or heading with legacy-only patterns that live in
files this PR does not touch (commands.cts:1766, commands.cts:2116,
init.cts:2241). The claim now states exactly what this slice delivers:
the scoped directory set. Their per-entry conversion is display work,
deferred to the epic's display PR with the statusline/progress-card
gates it belongs beside.

* fix(#2761): de-accident the unmatched-milestone bracket fixture, re-pin to #3480's withhold contract

tests/adr-612-bracket-phase-counting.test.cjs:515 ("a milestone that
does NOT match STATE is not scoped in") asserted total_phases === 0.
Since today's merge brought in 70b5c1a1 (#3354/#3480, already in
`next`), buildStateFrontmatter withholds total_phases (omits the key,
read back as null) for a milestone that is genuinely sectioned but
matches no ROADMAP heading, instead of substituting a computed number
— the fixture's `state json` read now returns null, failing the
strictEqual(0) assertion.

The original single-section fixture's 0 only ever survived by
accident: hasMilestoneSectioning requires >=2 milestone-vocabulary
headings to call a ROADMAP sectioned, and its isPhaseHeading helper
recognizes only the legacy `Phase N:` text form — so the bracket
phase heading `### [GSD.03] 09: Not this milestone` (title containing
the word "milestone") miscounted as a second milestone heading,
tipping hasMilestoneSectioning true and routing to the disk-count
branch. With that miscount removed, the same one-section fixture
reads 1 (the non-matching milestone's phase count leaking into v2.0's
total) — proving the pinned 0 was never validating the scoping this
test claims to exercise.

Replaced the fixture with two genuine milestone sections (GSD.03,
GSD.04), neither matching STATE's v2.0, with phase titles carrying no
incidental vocabulary — the real #3354 shape. Re-pinned the assertion
to null, matching upstream's own tested contract (tests/state-
document.test.cjs, "#3354 with nothing stored, the key is omitted
rather than written from the dir count").

Verified: file green 3/3 runs (104/104), full state-suite regression
771/771 green. The isPhaseHeading gap that made the old fixture
accidental is a real, pre-existing, upstream-owned limitation
(hasMilestoneSectioning only guards >=2-section conflation, not a
single non-matching section leaking through) — not introduced by

* chore(#2761): exempt two self-authored-fixture regexes from #3441's unbounded-quantifier rule

Both sites parse the STATE.md the test itself just wrote to its own
tmpdir — fixed-size fixture output, not adversarial or document-scale
input. Exempted with the justification-comment pattern the tree's own
tests use for this exact case (settings-integrations, copilot-install,
research-agent-profiles). The sites predate the rule; #3441 landed on
next this morning and this branch picked it up in the catch-up merge.

* fix(#2761): fix forward two next-movement test regressions from the round-11 rebase

origin/next's #3573 newly threads STATE's stored `milestone:` value into
`state json`'s buildStateFrontmatter call (previously always `undefined` on
that read surface). Two pre-existing PR-2 fixtures reach code paths that
call never exercised before that merge:

- RED (repro2 case C): a version-less, all-bracket-id ROADMAP now hits
  getMilestonePhaseFilter's pre-existing (unaffected by this branch) row-5
  `versionResolved && !headingFound => SCOPE.UNSCOPED` rule, which withholds
  `progress.percent` even though the scoped total_phases/completed_phases
  are still correct. That row-5 rule is load-bearing for six other
  version-less-document pins in this same file; narrowing it broke seven of
  them in testing, so production code is untouched here. Reassert the
  test's real claim (scoping, via total_phases/completed_phases) and
  disclose the now-withheld percent instead of silently dropping it.

- PIN (repro12 LEGACY control): a fenced-example-vs-real version heading
  fixture. #3573 routes this read through sliceMilestoneWindow (fence-aware)
  instead of the legacy anyMilestonePattern raw scan (fence-blind) this pin
  was disclosing as out of scope, so the fixture no longer exercises the
  blind path — total_phases moves from the whole-doc 4 to the correctly
  scoped 2. Re-pinned with an upstream-attributed comment, matching this
  file's existing house style for prior origin/next movements (see the
  sibling "PIN (G3 LEGACY control)" comment).

Both are test-only fix-forwards: no production code changed. The remaining
12 failures in this file at 27363e9d0 (dropped seam commits' VERIFICATION.md
naming + fixture updates) are pre-existing and deferred to the stacked
follow-up per the task's own scope.

* fix(#2761): thread phaseIdConvention explicitly at the two write-adjacent enumerator call sites (round-11 BLOCKER)

listMilestonePhaseDirs' phaseIdConvention param lost its `= null` default
(phase-locator.cts), so an omitted convention now means "resolve from
config" instead of "explicitly not bracket" — a deliberate flip, but
milestone.cts and state.cts were not in the PR-2 diff and both call the
enumerator without threading it:

- milestone.cts cmdMilestoneComplete (the single #3597 shared derivation
  feeding the stats loop, --dry-run preview, and the real archive/rename
  pass) now resolves phase_id_convention once and threads it explicitly,
  so a bracket project's `milestone complete` archives its real
  bracket-declared phase directories instead of silently inheriting
  whatever the enumerator's lazy default resolves to.
- state.cts cmdStateUpdateProgress's own enumerator call threads the same
  resolved convention. Empirically this does not change the #3217 withhold
  gate (scope is assigned before headingConvention resolves in
  getMilestonePhaseFilter, so it's convention-independent either way) or
  the reported percent (already correctly threaded via
  computeUpdateProgressPreview -> buildStateFrontmatter); it closes a
  second, silently-resolved answer to the same question this file's own
  ONCE-and-THREAD rule (~:2300) already states as policy.
- state.cts's other listMilestonePhaseDirs call site (the state-sync
  scope-only read, ~:4791) is left unthreaded on purpose, with an inline
  note explaining why: only `.scope` is consumed, and `.scope` is set
  before convention resolution in getMilestonePhaseFilter, so it cannot
  disagree with a threaded convention.

Both enumerated sets are pinned by new tests (round-11 BLOCKER block in
tests/adr-612-bracket-phase-counting.test.cjs), including a mutation-style
regression check on the milestone.cts fix (forcing the un-threaded default
back on makes the pinned test fail, catching a regression to the
pass-all-degrade legacy reading).

* fix(#2761): correct the changeset's false archival claim and amend ADR-612 for the round-11 M2(2) split scope

The changeset (.changeset/2761-bracket-read-tolerance.md) asserted "The
archival and milestone-completion paths are unchanged" — false: both
paths reach the widened enumerator, and this PR now threads their
convention explicitly (previous commit). Replaced the closing paragraph
with an accurate description of what changes for a bracket project at
those two call sites, and notes both enumerated sets are pinned by tests.

ADR-612 (docs/adr/612-bracket-phase-id-convention.md) amended per M2(2):
the 2026-08-03 PR-2/PR-4 boundary proposal is added in-body (PROPOSED,
not stamped — mechanics per docs/contributor-standards.md:143 reserve ADR
ratification to maintainers), rescoped to what actually ships in PR-2
(#2761) now that the round-11 M1 split moved the completion-seam
threading (isPhaseArtifact/scopeToPhase, phase-id.cts:964-1090) out into
a separate, stacked follow-up PR referenced generically via epic #612:

- state.cts read-tolerance (both total_phases derivations, the #1514
  retirement filter) moves into PR-2's row, alongside milestone.cts,

* fix(#2761): repair round-11 response gaps — disk-side sentinel bug, test-fixture bug, scanMilestonePhaseIds caller drift

Four independently-verified gaps in the round-11 repair response:

1. isSentinelPhaseId (src/phase-id.cts) treated a bare, untagged phase
   directory under phase_id_convention: "bracket" (`0-bootstrap`, no
   `{CODE}.{MM}-` prefix) as sentinel milestone 0 by falling through to the
   legacy leading-int rule when the bracket-tag match failed. This silently
   dropped a real, on-disk, milestone-declared phase directory from
   `listMilestonePhaseDirs` (phase-locator.cts:424, the only unguarded call
   site) and undercounted completed_phases/percent. Mirrors the carve-out
   already present on both heading-side counters (state.cts's
   countRoadmapPhaseHeadings guards its bare-0 exclusion with `bracketId &&`;
   roadmap-parser.cts's scanMilestonePhaseIds composes the bare-token rule as
   999-only) — under bracket convention, milestone 0 is expressed only via an
   explicit bracket tag, so an untagged leading 0 is a real phase token.

2. tests/adr-612-bracket-phase-counting.test.cjs's writeProject fixture
   hardcoded `01-VERIFICATION.md` for every "complete" phase dir regardless
   of the dir's real phase token. Under legacy convention this file already
   correctly failed #3511's strict isPhaseArtifact match for any dir other
   than phase 01 (the fixture never modeled what it claimed to); under
   bracket convention the pre-existing ambiguity fail-safe admitted it
   regardless. The two readings' disagreement was mistaken for a missing
   completion-seam threading (isPhaseArtifact/scopeToPhase convention
   awareness, correctly split out to the stacked #3644 per round-11's M1).
   Replaced the hardcoded name with verificationNameFor(dir), deriving the
   real per-phase filename from the production normalizePhaseName the same
   way cmdScaffold does — the 7 failing "flat-legacy-twin" / CHARACTERIZATION
   assertions pass on #2867's own code with no seam threading required, and
   the genuine seam-dependent cross-phase-stray-exclusion test the fixture
   fix would otherwise have hidden lives on the stacked branch instead.

3. tests/roadmap-parser.test.cjs's two #3577 tests still called
   scanMilestonePhaseIds with the old single-Set return shape; this PR
   changed it to `{ ids, qualifiedIds }` for every other caller but missed
   these two, which don't touch #2761/bracket code at all. TypeErrors at
   runtime, not silently-wrong assertions. Updated both call sites.

4. .changeset/2761-bracket-read-tolerance.md gains a paragraph disclosing
   fix 1 above, so the changeset stays accurate to what actually ships (the
   round-11 BLOCKER was exactly this changeset going stale once).

Verified: tests/adr-612-bracket-phase-counting.test.cjs +
tests/continuation-grammar-parity.test.cjs + tests/roadmap-parser.test.cjs =
354/354. adr-612-{coherence,grammar,heading-selection,read-tolerance,
selection.property}.test.cjs + collision-characterization = 287/287
(CONFIRMED-CLEAN set, unaffected). Full unfiltered suite run separately.

PR #3643 (round-11's M1 split, opened draft per that round's explicit
requirement) was auto-closed by this repo's own draft-PR policy 11 seconds
after opening — draft PRs are unconditionally closed here. Reopened as
non-draft #3644 (same branch, same commits, DO NOT MERGE / stacked-on-#2867
marker in the body, enhancement template) since the repo's own bot confirms
non-draft contributor PRs are tolerated even off-template.

* fix(#2761): narrow the state-update-progress pin claim to what mutation testing actually proved, add the test that covers the rest

Round-11 BLOCKER response gap (verified, not a guess): the changeset and
ADR-612 amendment point 2 both claimed the round-11 tests pin
`cmdStateUpdateProgress` so "a future change to the enumerator's default
cannot silently move ... what state update-progress reports without failing
a test." Mutation testing disproves this. Reverting BOTH the state.cts
explicit `phaseIdConvention` thread AND simulating the phase-locator.cts
pre-#612 hardcoded-null default (`phaseIdConvention: null` at that one call
site) leaves the existing PIN test ("writes a real percent for a
bracket-scoped milestone") green, because that percent comes from
`computeUpdateProgressPreview` -> `buildStateFrontmatter`, a separately and
already-correctly-threaded derivation the state.cts inline comment at ~:965
already candidly documents.

What the reverted thread DOES change, empirically, is `phaseDirs`/`totalPlans`
— the enumerated `.value` this call site feeds into the #3233 zero-plans
no-op gate a few lines below. That is the one place a regression at this call
site is observable in the command's output. Added a test that pins exactly
that: a bracket milestone whose declared phases carry no plans on disk,
alongside a decoy directory that plainly does not belong to the milestone
(no bracket tag, no phase token) but does have a plan. Correctly scoped, the
decoy is excluded and the #3233 no-op fires (`updated: false`). Degraded to
the pass-all legacy reading, the decoy is swept in, `totalPlans` flips
nonzero, and the no-op never fires (`updated: true`).

Mutation-tested against both scenarios:
- Reverting ONLY the state.cts explicit thread (falls back to `undefined`,
  which `getMilestonePhaseFilter` resolves via the identical
  `resolvePhaseIdConvention(cwd, undefined)` call the explicit thread also
  makes): new test stays green — confirms the single-hunk thread really is
  pure single-derivation hygiene, exactly as the existing inline comment
  claims, for this test too.
- Forcing `phaseIdConvention: null` at that call site (the combined-revert
  scenario the round-11 mutation testing actually exercised): new test FAILS
  (`updated: true, percent: 0` instead of the expected `updated: false`).
  Restoring the real code makes it pass again.

Narrowed the changeset and ADR-612 point 2 prose to match: `cmdMilestoneComplete`'s
enumerated set is pinned against a pass-all-degrade regression (genuine,
already verified in round 11); `cmdStateUpdateProgress`'s own call site is now
pinned against the #3233 zero-plans no-op specifically, not against the
reported percent, which the prose no longer claims. Added a one-line pointer
to the new test in the state.cts inline comment. No production behavior
changes — test and documentation only.

* docs(#2761): reconcile ADR PR-2 module map

* fix(#2761): restore #3639's dir-aware W007 sentinel exclusion lost in the rebase replay

The rebase replayed this file's pre-#3639 patch over next, reverting the
isSentinelPhaseId(token) -> isSentinelPhaseDir(dirName) fix: the extracted
token is milestone-stripped, so a bracket sentinel (GSD.999-07-icebox,
GSD.00-01-backlog) was invisible to the id predicate and false-fired W007.
Restores upstream's call and comment verbatim; the branch's convention-aware
token remains for the diagnostic message only.

Caught by next's own #3639 regression tests (CI shard 2). Local: the file's
18/18, health-diagnostic-rules 165/165, full npm test exit 0.

* docs(#2761): ratify scope and correct surface claims

* test(#2761): strengthen legacy selection and drift claims

* docs(#2761): correct the enumerator claim, scope list, and ratification receipt

Three documentation corrections, none touching production code.

The changeset claimed the shared phase-directory enumerator "now defaults its
convention argument to 'not yet resolved' rather than 'resolved, and not
bracket'". That is false: `phase-locator.cts:375` still destructures
`phaseIdConvention = null`, and the lazy resolve-from-config fires only on
`undefined` (`roadmap-parser.cts:941`, `:1928` — whose own comment records that
"explicit null still means 'resolved and non-bracket'"). Measured: only 4 of 17
`listMilestonePhaseDirs` call sites thread a resolved convention (`milestone
complete` and `state`'s three). The changeset went on to name `progress`,
`stats`, `phase list` and the init manager view as now receiving a correctly
scoped set — those are precisely callers that omit it. Replaced with what the
code does, and the deferral stated plainly.

The ADR's PR-2 row omitted `scripts/lint-phase-id-drift.cjs` (+141/-14) and
`scripts/lint-phase-enumeration-drift.cjs`, both changed by this PR. An
under-claim rather than an over-claim, but the row is the epic's
scope-of-record.

Ratify item 5 asserted maintainer ratification while citing only the review that
raised the question. It now cites the review that granted it (#2867 review
`5012940978`, 2026-08-24) and quotes its terms, so the claim carries its receipt.

Found by an adversarial review pass over the round-12 diff. (#2761)

* fix(#2761): drop the no-op --json that strict argv now rejects

Surfaced by the rebase onto next, not by a change in this PR's subject.

#3884 ("failure is a value — strict argv", e20744eac) made an unrecognized
flag a hard error: `state validate --json` now exits 1 with
`unknown flag "--json"; accepted: --strict` on stderr and EMPTY stdout,
where the token was previously accepted and ignored. `state validate` never
had a `--json` flag — JSON is its only output shape — so the argument was a
silent no-op from the start.

The helper parsed that empty stdout, so all five subtests in the
"state validate resolves bracket phase DIRECTORIES" suite failed identically
with `SyntaxError: Unexpected end of JSON input` at the JSON.parse, masking
what they actually assert.

Dropping the token restores the same envelope the helper already parsed. No
assertion changes. Verified against the fixture the suite builds: exit 0, and
the output carries the S005 plan-count warning the drift assertions require
with no S004 phase-directory warning — i.e. the bracket directory resolves,
which is the behaviour these tests exist to pin. 94/94 in the file.

* fix(#2761): exempt the phase-counting suite from the docs-guard lane

Surfaced by the rebase onto next. #3753 (107eb8c1d) added
lint-docs-guard-registration, which requires every test file that reads a
docs/ path to be either registered in the docs-guard lane or carry an
explicit marker. It flags adr-612-bracket-phase-counting.test.cjs, which
reads no docs/ path at all.

The file's only docs/ occurrence is the ADR-612 Decision 1 citation in a line
comment; every read call it makes targets a tmpdir .planning fixture. It trips
Detector 3, whose DOCS_TEMPLATE_LITERAL_RE sees an odd prose backtick in the
comment block above that citation as opening a template literal and reads the
span between them — citation included — as a docs/ path expression. That
detector documents this trade in its own header: it favours recall, and says a
false positive costs one docs-guard-exempt marker with a reason. The baseline
records the same class ("comment-only mentions") for 46 of its entries.

Registration was the wrong side of the trade here: it would run this suite in
the docs-guard lane on docs/ changes whose content it never reads.

Three pieces, matching what the gate requires and what its 54 existing entries
already do:
  - the marker in the file's header window, written without backticks so it
    cannot itself disturb the parity tracking findExemption does;
  - the basename in DOCS_GUARD_EXEMPT_BASELINE, since the ratchet fails a new
    marker until the baseline is deliberately updated — the reviewable diff is
    the point;
  - the FIX 3 per-file fingerprint, derived with the lint's own
    extractDocsPathReferences rather than retyped, so the exemption fails loudly
    if the set of docs/ paths this file mentions ever changes.

Gates: lint-docs-guard-registration 0 violations, ci-docs-guard-registry 51/51.

* docs(#2761): correct the bare-0 comment and state what opting into bracket costs

Round-13 review items Minor 2 and Minor 3, both still live on the previous head.

Minor 2 — src/phase-id.cts. The comment block claimed "Bare `0` is admitted
alongside it because a 0.x sentinel is a legitimate identity that predates
padding", which contradicted both the shipped constant and its own next
paragraph. BRACKET_CANONICAL_NUMERIC_SOURCE is `(?:[1-9]\d{2,}|\d{2})`;
measured against it, `0` is rejected while `00`, `05`, `99`, `100` and `999`
are admitted. The paragraph four lines below already recorded the removal
("the earlier `(?:\d{2,}|0)` ... admitted ... a bare `0` that pad2 never
produces"), so the block asserted and denied the same fact. The stale sentence
is replaced with what ships: `00` is the backlog sentinel's canonical padded
identity, `\d{2}` already covers it, and nothing needs the unpadded spelling.
No behaviour change — the constant is untouched.

Minor 3 — docs/CONFIGURATION.md. The phase_id_convention row described the
read-path widening but never said what a repo GIVES UP by opting in. Added:
on a bracket repo a heading whose bracket is followed directly by a digit is
read as a phase heading, so `### [RFC.2119] 5:`, `### [v1.0] 2024:` and
`### [ADR.612] 3:` — legal prose headings under any other convention — are
claimed as phases and move phase_count, total_phases and W006. Those three
shapes are the ones phase-id.cts's own selector comment names as the reason
the widened read is selected at construction time from this value rather than
applied everywhere; the row now carries that trade instead of only its
upside.

Gates: tsc --noEmit exit 0, npm run lint:ci exit 0, npm run test:unit
33890/33891 with the single failure being emitted-attribution's base drift
against a next that moved after the rebase (133/133 against the rebase base;
this push re-bases onto the current tip, which resolves it).

* fix(#3648): resolve base_branch precedence inversion and round-1 findings

Blocker 1/2: production config resolution was flat-first, so a project
that migrated to git.base_branch but still carried a stale flat
base_branch got the old value back. Add base_branch to
normalizeLegacyKeys (mirrors the existing branching_strategy/sub_repos
pattern: canonical nested wins) and route readEffectiveGitConfig's
test seam through the same normalization so it can't silently diverge
from production again. Adds a regression test with both keys set that
fails without the fix.

Blocker 3/4/5: restore the handle_branching case-selector prose and
"none" contract sentence that #3389's tests anchor on, and revert the
unrelated prose/comment compaction in the same step — both were
drive-by edits outside #3552's scope.

Also addresses review majors/minors: delete readConfigBaseBranch and
readConfigProtectedBranches (dead in production, only self-tested);
--is-protected now fails closed (reports protected) instead of
silently answering false when the base branch can't be verified;
trim configured protected-branch names; fix HOME-without-USERPROFILE
vacuous isolation on Windows; correct the drift-ack's byte accounting.

* test(#3648): add failing legacy-key hoist safety coverage

Round-2 review found normalizeLegacyKeys block 5 records a normalization
carrying the DISCARDED flat value on the canonical-wins branch. Probing
that turned up a second, unreported defect in the same helper shape:
blocks 1, 2 and 5 all spread result['git'] / result['planning'] with no
object guard, so a config whose section key holds a string is spread into
index keys —

  {"git":"main","base_branch":"release"}
    -> {"git":{"0":"m","1":"a","2":"i","3":"n","base_branch":"release"}}

The resolved value is accidentally still correct, so nothing fails and no
diagnostic fires. But normalizations.length > 0 sets configDirty, and
config-loader then serializes that shape back into the user's
config.json — a read that silently corrupts config.

The deleted #3057 W3 suite covered {"git":"main","base_branch":"release"}
explicitly; this is the input it would have caught.

Covers both defects across blocks 1 and 5, with object/array/null
negative controls that must stay green in both phases, and a fast-check
property over arbitrary `git` values.

* test(#3648): pin fail-closed handling of malformed protected_branches

Replaces the test that pinned the fail-OPEN behaviour. The old
assertion — ['develop', 42] yields isProtected === false for 'develop' —
locked in the exact failure #3552 exists to close: config-set validation
is bypassable by a direct edit of .planning/config.json, so a user who
believes 'develop' is protected got a silent false and no warning.

It was also inconsistent with the fail-CLOSED direction twelve lines
away, where an unverified base reports protected and writes a
diagnostic. A protection predicate must not have two opposite failure
directions depending on which input is bad (#3648 review Blocker 3).

New coverage: a bad element drops only itself, a non-array contributes
no names, an empty list is well-formed rather than malformed, and
--is-protected surfaces the rejection. Both negative controls — a clean
list reports nothing rejected and writes no diagnostic — must stay green
in either phase, so the reject channel cannot fire unconditionally.

* fix(#3648): drop only invalid protected_branches and report them

Partition git.protected_branches instead of discarding the whole list on
one bad element, and carry the rejections out through
ProtectedBranchStatus so --is-protected can name them on stderr. Valid
names keep protecting; the user finds out the rest were ignored.

A non-array value still contributes no names — a bare string is not a
list of branch names — but is now reported rather than swallowed. An
empty array stays silent: declaring no extra protected branches is a
valid choice, not a misconfiguration.

writeDiagnostic is hoisted out of the unverified-base branch since both
arms now use it.

* test(#3648): prove the predicate diagnostic survives both call sites

The workflow bash stub now emits a stderr diagnostic the way the real
command does, which is what makes a swallowed `2>/dev/null` visible to a
test — previously the stub was silent on stderr, so discarding it changed
no observable behaviour and the call sites could drop the explanation
undetected.

Adds the Minor 2 binding check as well: ship must expose the predicate
result as IS_PROTECTED rather than only echoing a warning, asserted by
running the extracted bash and reading the bound value, not by grepping
the workflow source.

Both tests carry opposite-outcome controls — an empty diagnostic must
leave the text absent, and a false predicate must bind false.

* fix(#3648): surface the predicate diagnostic and bind ship's result

Drop `2>/dev/null` from the --is-protected call at both call sites. The
fail-closed explanation and the new rejected-entry warning both go to
stderr, so discarding it left the user with a bare "protected branch"
warning on a branch that is not protected and no way to tell a real
match from a degraded-git guess. `git branch --show-current` keeps its
own redirect — that one is genuine noise.

ship.md binds IS_PROTECTED and its prose now branches on the variable,
so the following steps have evaluable state instead of having to infer
it from warning text in tool output.

execute-phase.md byte accounting refreshed: 92326 -> 92645, net growth
319 bytes (was 331 before the redirect came out). Baseline re-verified
against the current rebase base by blob id; the ceiling check passes
with 755 bytes of margin.

* test(#3648): restore negative space for the readFile config seam

The #3057 W3 suite was deleted with readConfigBaseBranch, but every arm
it pinned survives verbatim in readEffectiveGitConfig's readFile branch —
the JSON.parse catch, the non-object guard, the git-section object guard,
.trim() and blank-string rejection — and the four surviving readFile
injections were positive-path only. protected_branches was never driven
through this seam at all.

Restores nine cases against the seam, including protected_branches
partitioning, plus a control proving loadConfig still wins when both
seams are supplied.

Records honestly what the suite pins. Mutating the built lib shows
.trim() is KILLED, while the non-object guard and the blank-string
rejection SURVIVE — both are unreachable through this entry point for
the same reasons the deleted suite documented against its own
equivalents: a JSON-parsed non-object carries no relevant own-property
either way, and a blank value is rejected a second time downstream by
the resolver's truthiness check. They stay as defence-in-depth and are
labelled known-unkillable rather than left looking like coverage this
suite does not provide.

* test(#3648): distinguish detached HEAD from a missing branch argument

`args[1] ?? ''` collapsed two different situations into one: a detached
HEAD, where `git branch --show-current` legitimately prints nothing, and
the flag being called with no argument at all. Both answered false, so
the right outcome arrived by an unintentional path and a caller bug was
indistinguishable from normal operation.

Asserts the detached case stays silent and the missing-argument case
reports, with a control that the two diagnostics differ.

* fix(#3648): report a missing --is-protected branch argument

Answer false either way, but say so when the flag arrives with no
argument. A detached HEAD passes an explicit empty string and stays
silent, since that is a normal state rather than a misconfiguration.

* docs(#3648): state exact-name matching and per-entry rejection

isProtected is exact string equality, so a git-flow project must
enumerate every release/* and hotfix/* by name. #3552 only asked for an
integration-branch field, so the implementation satisfies the letter of
the issue while leaving its git-flow motivation partly unserved — say so
where users will meet it rather than leaving them to discover it.

Also documents the Blocker 3 behaviour change: an invalid entry is
ignored with a warning naming it and the remaining names still apply.

Both statements land in docs/CONFIGURATION.md and
gsd-core/references/planning-config.md, and the config-field-docs parity
test asserts each in both so the two cannot drift.

* refactor(#3648): extract isValidProtectedBranches for cross-surface pinning

The `git.protected_branches` check inside `cmdConfigSet` and the resolver's
per-entry filter in `git-base-branch.cts` are deliberately different shapes —
all-or-nothing on write, per-entry on read, so a hand-edited config.json cannot
fail the guard open. Nothing structural keeps their two definitions of "usable
branch name" in step.

Lifting the write-side check into a named, exported predicate lets a property
test ask both surfaces about the same value and assert they agree, which is the
fast-check gap the round-2 review flagged. No behaviour change: the predicate is
the same expression, called from the same place.

* fix(#3648): stop --is-protected rewriting the config it is asking about

`gsd_run query git.base-branch --is-protected` runs on every execute-phase and
every ship. It resolved config through `loadConfig`, whose normalize-then-write
path rewrites `.planning/config.json` whenever any legacy key normalizes — so a
boolean question was silently editing the user's checked-in config. This PR had
widened the trigger by adding a fifth normalization block (top-level
`base_branch` -> `git.base_branch`), making it fire for exactly the projects the
feature targets.

`loadConfigResolved` gains `options.persist` (opt-OUT, default true): resolution
is unchanged, only the two write-back side effects are suppressed. The predicate
passes `persist: false`; the ~30 other callers are untouched, so a legacy config
is still migrated by ordinary use.

Asserted on BYTES rather than parsed shape, because the rewrite reorders keys and
reflows whitespace even when the values are equivalent. Three tests, each with
its own control: the end-to-end CLI leaves the file byte-identical while still
answering `true` from the legacy key (proving the config WAS read); an ordinary
persisting load of the same fixture DOES change the bytes (proving the fixture
is live rather than inert); and `persist:false` vs default over one directory
returns deep-equal config while differing on the write. Reverting the one-line
`persist: false` fails the first of those and only that one.

Also from the review:

- `readEffectiveGitConfig`'s comment claimed the readFile branch routed "through
  the same precedence authority production uses". It does not, and cannot — it
  reproduces two of production's steps over a single file. The comment now names
  what the seam covers and what it does NOT (root/workstream deep merge, builtin
  and global defaults, federated merge), and the seam now applies production's
  flat-then-nested lookup so it stops disagreeing about a surviving flat key.

- The missing-argument diagnostic promised "answering false", which the
  fail-closed guard on the same call can contradict by printing `true`. It now
  states what it did with the argument and leaves the answer to stdout.

* test(#3648): re-pin block 5 on #3760's refusal contract

#3767 landed on next while this PR was in review and fixed the non-object
config-section defect properly: a present-but-non-object section now BLOCKS its
own migration — value preserved, no Normalization pushed, refusal reported via
`skipped[]` — rather than being rebuilt from a plain-object view. That supersedes
this branch's round-2 `hoistLegacyKey`, which prevented the character-key spread
but still dropped the section value silently, and which the round-3 review
correctly called out as destruction in place of corruption. The rebase drops that
commit and routes block 5 through the upstream helper.

This file's tests asserted the superseded design, so they are rewritten to pin
block 5 — `base_branch` -> `git.base_branch`, which did not exist when #3760's
suite was written — against the contract that now governs it: ordinary hoist into
an absent/null/object section, canonical-nested-wins, and refusal for each of
string/number/boolean/array sections with the exact `skipped` entry.

Two controls keep it from passing vacuously: the refusal must be scoped to block
5 (an unrelated block still normalizes in the same call), and a property over
arbitrary `git` values asserts hoist and refusal are exhaustive AND mutually
exclusive per key, that a refusal leaves both the section and the legacy key
untouched, and that a hoist manufactures no index key the input did not carry.

* docs(#3648): correct the Git Query and Config Loader module contracts

CONTEXT.md's Git Query Module still described base-branch tier 1 as a direct
`.planning/config.json` read. Since this PR it is the EFFECTIVE configuration
resolved by the Config Loader — a materially different authority, carrying the
root/workstream deep merge, flat-then-nested lookup and builtin/federated
defaults. The `--is-protected` predicate, `git.protected_branches`, and the two
invariants that distinguish the predicate from the plain query (fails closed on
an unverified base; must not write) were undocumented entirely.

The Config Loader entry now states that loading is not side-effect-free by
default and documents `options.persist`.

docs/INVENTORY.md's `git-base-branch.cjs` row carried the same stale ladder and
no mention of the predicate. `node scripts/gen-inventory-manifest.cjs --write`
was run and produced no diff: the manifest indexes roster NAMES, not row prose,
so a description edit cannot move it.

Also closes the global-defaults minor: `git.protected_branches` is inert in
`~/.gsd/defaults.json`, but so is every other `git.*` key — no branch-policy key
appears in `_globalBaseCfg` or `GLOBAL_DEFAULTS_RESOLUTION_KEYS`. That is
section-wide and predates this PR, so the fix is to state the scope where users
meet it rather than to quietly extend the resolution set for two new keys.

* fix(#3648): close four defects found by the round-4 external review

Two external reviewers (codex, antigravity/Gemini 3.1 Pro) were run adversarially
against this branch. Four findings reproduced against source; each is fixed with a
failing-first test and a control, and each fix was verified by reverting it and
watching exactly the intended test fail.

1. `persist:false` was DROPPED by the workstream fallback (codex). Blocker 1 was
   only half closed. `loadConfigResolved` re-enters itself with a bare
   `{ workstream: null }` when a workstream has no config.json of its own, and
   that literal discarded every other option — so the recursive pass ran at the
   DEFAULT persistence and rewrote the ROOT config. Reproduced: with
   GSD_WORKSTREAM=alpha and a legacy flat `base_branch`, `--is-protected`
   rewrote `.planning/config.json` despite `persist:false`. Both recursions now
   forward `options` and override only `workstream`; the explicit override still
   wins the hasOwnProperty check, so spreading cannot let `workstreamContext`
   reintroduce a workstream.

2. Both workflow call sites failed OPEN, and aborted under `set -e` (both
   reviewers, independently). `IS_PROTECTED=$(gsd_run ...)` yields an empty
   string when the query fails, so `[ "$X" = true ]` was simply false: no
   warning, no trace — a silent hole in the guard whose only job is to warn. The
   bare assignment also aborted the step under `set -e`. Both sites now degrade
   VISIBLY: `|| IS_PROTECTED=""`, then an explicit empty-string arm that says the
   check did not run. Deliberately not fail-closed — claiming "protected" on no
   evidence would warn on every branch whenever gsd-tools is unavailable.

3. `isValidProtectedBranches` and the resolver disagreed on a sparse array
   (antigravity). `.every()` skips holes; the resolver's `for...of` yields
   `undefined` for them, so `["main", , "develop"]` was accepted by config-set
   and rejected by the resolver. The cross-surface property passed only because
   `fc.array` cannot generate a hole. The predicate now indexes, and the
   generator punches holes so that axis is actually falsifiable. JSON cannot
   express a hole, so this is unreachable in production — but two definitions of
   one predicate must not contradict each other.

4. A top-level `protected_branches` silently outranked `git.protected_branches`
   (antigravity). Routing the key through `get(key, {section, field})` gave it
   flat-then-nested precedence, which is back-compat for keys
   `normalizeLegacyKeys` migrates. `protected_branches` is new in #3552 and has
   no legacy form, so that invented an undocumented alias. It now resolves
   nested-only through a new `getNested`, in production and in the test seam.
   `base_branch` keeps flat-then-nested — it HAS a legacy spelling that #3760's
   refusal path can leave behind — and a control pins that distinction.

Also narrows a CONTEXT.md claim this round introduced. The predicate fails closed
only when a git query TIMED OUT or could not be spawned (#3057 B4's `verified`);
a git command that runs and exits non-zero counts as a clean negative, so a cwd
that is not a repository answers `false`, not `true`. Verified pre-existing on
next @ 738f42f4, so the documentation was over-claiming rather than the code
regressing — but an over-broad contract is exactly what the module docs must not
carry.

Both workflow byte figures re-derived after the call-site change:
execute-phase.md 92356 -> 92865 (+509), ship.md 36784 -> 37227 (+443).

* test(#3648): pin git config read parity

* docs(#3648): document git query contracts

* fix(#3648): expose protected branch default

* test(#3648): snapshot planning tree for read-only query

* test(#3648): pin planning snapshot stray-write detection

* fix(#3648): resolve merge conflict from #3078's ack-fragment sweep

next swept the fully-spent 2818/3003 ack fragments this branch had
appended to (#3078, a84f7563). Rebased onto upstream/next and took
the deletions on both, then moved the #3552 append into a new
fragment of its own.

Rebasing onto the current base also left execute-phase.md only 34
bytes under the frozen ADR-857 Phase 6 margin ceiling (93400 bytes) —
intervening next PRs consumed the rest while this PR was in review.
Extracted the "none" arm's protected-branch-warning bash block into
gsd-core/workflows/execute-phase/steps/protected-branch.md (content
unchanged, matching the existing steps/ extraction pattern used
elsewhere in this file) so the inline growth is a one-line pointer
instead of the full block. 93366 -> 93385 bytes (+19), 15 bytes
inside the ceiling.

* fix(#3648): drop stale ack entry for the new step file

The extracted execute-phase/steps/protected-branch.md needed no
acknowledgment of its own — the differential-attribution check flagged
the entry as stale once the build ran, so removed it and kept the two
growth entries (execute-phase.md, ship.md) that actually needed one.

* fix(#3648): follow the step-file reference in the bash-extraction test helper

extractProtectedBranchWarningBash() read the "none" arm's bash block
directly out of execute-phase.md. That block now lives in
execute-phase/steps/protected-branch.md (byte-ceiling extraction);
the helper follows the step-file reference and extracts from there
when no inline block is found, so the three execute-phase tests that
execute this bash for real keep exercising the actual behavior.

* fix(#3648): regenerate INVENTORY-MANIFEST.json and satisfy the CRLF-fragile lint rule

- gen-inventory-manifest.cjs --write to pick up the new
  execute-phase/steps/protected-branch.md entry (already covered by
  docs/INVENTORY.md's generic workflow_steps wildcard row, so no
  INVENTORY.md edit is needed).
- Reworked the step-file-reference lookup in
  extractProtectedBranchWarningBash() to avoid a bare-\n regex split
  on file content (local/no-crlf-fragile-split), using the same
  line-array scan the function already uses elsewhere.

* fix(#3648): regenerate golden install-tree fixtures for the new step file

npm run gen:install-tree, adding gsd-core/workflows/execute-phase/
steps/protected-branch.md to all 19 runtime install-tree fixtures.
CI's tests/golden-install-tree.test.cjs caught this on push — I'd
verified the differential-attribution and INVENTORY-MANIFEST checks
but missed this separate golden-fixture check for the new file.

* fix(#3648): add the canonical gsd_run preamble to the new step file

CI's runtime-launcher-parity suite requires exactly one canonical
resolver preamble in every workflow .md that calls gsd_run. The
inline "none"-arm block never needed one (execute-phase.md already
carried a preamble elsewhere in the same file), but the extracted
execute-phase/steps/protected-branch.md is now its own file with no
preamble of its own. Ran node scripts/sync-runtime-launcher.cjs to
insert it (execute-phase.md itself is untouched — still 93385 bytes,
inside the ADR-857 ceiling).

That preamble defines its own gsd_run(), which shadows the mock
tests/git-base-branch.test.cjs injects for the three #3648 tests that
execute this bash for real — without stripping it, those tests reached
the real gsd-tools.cjs on the machine running them instead of the
test's fixture. Preamble correctness is already covered by
tests/runtime-launcher-parity.test.cjs, so extractProtectedBranchWarningBash()
now strips the preamble line before handing the block to the harness;
it only needs to exercise the #3552 warning logic.

* fix(#3552): address PR 3648 review feedback on protected branch warnings

- Fix execute-phase handle_branching branching_strategy=none instruction
  to "Read and execute execute-phase/steps/protected-branch.md"
- Use io.error(..., ERROR_REASON.USAGE) for cmdGitBaseBranch usage errors
- Align git.protected_branches schema default to (none) without fallback []
- Relocate CONTEXT.md forward-referencing sentence into module body
- Sanitize control and ANSI characters in renderRejected diagnostics
- Clean up out-of-scope whitespace hunks in gsd-tools.cjs

Emitted-Drift-Ack-Growth: execute-phase.md — #3552: execute-phase handle_branching adds a pointer to execute-phase/steps/protected-branch.md for branching_strategy=none so the protected-branch check executes while keeping execute-phase.md within the ADR-857 Phase 6 margin ceiling (93400 bytes). 93392 bytes, 8 bytes inside the ceiling.
Emitted-Drift-Ack-Growth: ship.md — #3552: ship preflight step 3 now asks the same typed git.base-branch --is-protected predicate as execute-phase, binding IS_PROTECTED and warning without refusing execution or blocking the branching_strategy=none feature-branch offer; it degrades visibly (rather than silently reading an empty result as "not protected") when the query itself fails to run. 36841 bytes, well inside the XL cap (98304, tests/workflow-size-budget.test.cjs).

dd4f179672 feat(#3970): per-task external-tracker content-resolution seam (#4000)
* feat(#3970): per-task external-tracker content-resolution seam

Implements ADR-3646 (Phase 1, #3970): a `<task tracker-id="...">` attribute
plus a new optional `taskContentResolver` capability-manifest field let a
capability resolve a task's action/verify/acceptance-criteria/read_first/done
content from an external issue tracker instead of PLAN.md's inline body.

- src/plan-document.cts: parses the `tracker-id` attribute into `PlanTask.trackerId`
- src/task-content-resolution.cts: new leaf module — split/find/build/resolve,
  with a hard-halt (throw) contract on ambiguous/failed/timeout/malformed
  resolution, never a silent fallback to possibly-stale inline text
- src/task-command-router.cts: new `task resolve-content --plan --task-id --raw`
  CLI verb wiring the module into a real process exit code
- gsd-core/bin/lib/capability-validator.cjs: validates the new
  `taskContentResolver` manifest field (feature-role only, cross-capability
  trackerPrefix uniqueness)
- gsd-core/workflows/execute-plan.md, gsd-core/references/loop-hook-dispatch.md,
  docs/reference/capability-manifest.md: wire the seam into the per-task loop
  and document it as a new `execute:task` point outside the existing
  contribution/step/gate vocabulary (unconditional in autonomous mode)

Closes #3970

* fix(#3970): gate checkpoint tasks out of content resolution, close trackerPrefix grammar parity gap, cover path-traversal guard

Standards/Spec code-review pass on the task-content-resolution seam (ADR-3646
Phase 1) found three defects:

1. execute-plan.md's task-content-resolution bullet fired on any
   tracker-id-bearing task with no check that it wasn't type="checkpoint:*",
   contradicting ADR-3646 Decision 1 (a checkpoint task must never enter
   resolve-content). plan-document.cts already parses trackerId: null
   unconditionally for checkpoint tasks; only the workflow prose needed the
   fix, so the bullet now explicitly excludes checkpoint tasks.

2. task-content-resolution.cts's parseResolverDeclaration accepted any
   non-empty trackerPrefix with no grammar check, while capability-
   validator.cjs's KEBAB_RE enforces kebab-case at install time — a
   Generative Fix Divergence gap. Added the same grammar (as a literal
   regex, documented as intentionally not shared across the .cts/.cjs build
   boundary) plus a parity test asserting the two surfaces agree across a
   valid/invalid trackerPrefix table.

3. task-command-router.cts's routeResolveContent path-traversal guard on
   --plan had zero test coverage. Added a test exercising a
   ../../../etc/passwit-shaped path and asserting the USAGE rejection names
   the offending path.

* fix(#3970): sanitize resolver diagnostics and cap resolver timeoutMs

Two findings caught by an isolated security-review pass on the task
content resolution seam:

- ResolverFailedError/ResolverMalformedOutputError embedded raw,
  unsanitized subprocess stderr/stdout (attacker/model-influenced via
  the tracker-id argv token) into .message. A hostile or buggy resolver
  could smuggle a newline plus a forged "Error: " line, or terminal
  escape sequences, into a diagnostic io.cjs's error() writes verbatim
  to stderr. Fixed at the constructor (task-content-resolution.cts) via
  io.cjs's existing formatDiagnosticToken(), so every caller of
  resolveTaskContent gets a safe .message by construction.

- capability-validator.cjs's validateTaskContentResolverFields had no
  upper bound on taskContentResolver.invoke.timeoutMs, letting a
  manifest declare an effectively unbounded value and defeat the
  "bounded subprocess" design intent. Added a 120000ms ceiling specific
  to this field, without touching the shared isPositiveIntegerMs()
  helper (still used unbounded by the reviewer lane's timeoutFloorMs
  and probe timeoutMs).

* fix(#3970): fix gsd-test failures — stale prose allowlist line and stderr-vs-message assertion

gsd-test (remote dockerized matrix) came back red with 5 failures on this
PR; all five are real defects, fixed here.

- tests/no-bare-gsd-tools-command-position.test.cjs: PROSE_ALLOWLIST's
  execute-plan.md entry pointed at line 415, which ffc190df4's
  checkpoint-exclusion caveat (added near line 221) shifted down by one
  line. The actual "validated downstream by gsd-tools uat
  classify-coverage" descriptive mention now sits at line 416. Updated
  the allowlist entry's line number to match.

- tests/task-command-router-resolve-content.test.cjs: the path-traversal
  test asserted the outside-project-scope diagnostic against the thrown
  ExitError's own .message. io.cts's error() (ADR-3889) writes its
  human-readable message to fd 2 via writeAllSync and then throws a bare
  `new ExitError(1)` with no message argument — by design, so the
  exception carries no duplicate text and the thrown ExitError's message
  defaults to "process exit 1" (cli-exit.cts's ExitError constructor).
  Root cause was the test, not the source: task-command-router.cjs's
  outside-project-scope rejection already calls error() correctly and the
  diagnostic text is genuinely emitted, just on fd 2, not on the
  exception. Fixed the test to capture fd-2 writes (mirroring
  tests/estimate-calibrate.test.cjs's runCalibrateExpectError and this
  same file's own captureStdout for fd 1) and assert against the captured
  stderr text instead of err.message. This was masked locally because a
  manual `node -e` sanity check that only inspects the caught exception's
  .message cannot see what the real node:test run actually failed on.

Emitted-Drift-Ack-Growth: execute-plan.md — adds the ADR-3646 task-content-resolution bullet and checkpoint-exclusion caveat to the per-task execute loop; a real behavioral prose addition, not incidental bloat.

* enhance(#3624): local/no-exact-case-env-access — ratchet ADR-1703 onto production env reads (epic #3411 Phase 4)

Extends ADR-1703's portability rule catalog with a second production-runtime
rule: it flags an exact-case read of a Windows case-varying environment
variable (PATH, PATHEXT, ComSpec, USERPROFILE, TEMP, TMP, APPDATA) off any
receiver that is not process.env itself, matched via an env-shaped-receiver
check to avoid colliding with ordinary `.path`-named properties elsewhere in
the tree.

Exports the seam's private `_envGet` as `envGet` so the rule's remediation
message names a real helper, and fixes the one pre-existing violation the
tightened rule found (`src/runtime-hooks-surface.cts`'s `env.APPDATA` read).

Closes #3624

* fix(#3624): extractStaticName recognizes non-computed Literal destructuring keys; add missing accessor-call test case

Review findings from the code-review + isolated-adversarial passes:
- extractStaticName only matched non-computed Identifier keys, so a
  destructuring like `const { 'PATH': v } = opts.env;` (the issue's own I8
  acceptance case) silently evaded the rule. Widened to accept a Literal key
  regardless of computed, which is safe for MemberExpression too (its
  non-computed property is always an Identifier by grammar).
- Added the missing RuleTester valid case for "a case-insensitive accessor
  call" (envGet(env, 'PATH')) from the issue's Done-when checklist.

* feat(#3626): make CONTEXT.md seam claims checkable via SEAM.*.enforced-by gate

Adds SEAM.<id>.owns / SEAM.<id>.enforced-by=lint-rule:<name>|test:<path>
predicates to CONTEXT.md, generalizing the existing WORKTREE.SEAM.* shape,
plus scripts/lint-seam-enforcement.cjs (wired into lint:ci) which fails
when a declared single-owner seam names no existing, registered
enforcement mechanism. Backs all six current module-level single-seam/
single-canonical-owner claims found in CONTEXT.md, including the Shell
Command Projection Module's Windows-binary-resolution claim via #3619's
local/no-private-binary-resolution rule.

Scope is resolves-only per maintainer decision: the gate proves an
enforcement pointer exists and is registered, not that its surface
covers every file the seam claims. See docs/adr/3626-context-md-seam-claim-gate.md.

Closes #3626

* fix(#3626): back the Package Identity Module's seam claim too

Isolated adversarial review caught a miss in the "no grandfather list"
sweep: the Package Identity Module also declares itself "Single seam
owning GSD's published-package coordinates" and already names its real
enforcement (scripts/lint-package-identity-drift.cjs). Backs it with
SEAM.package-identity.owns/enforced-by=test:tests/package-identity.test.cjs,
bringing the total to 7 backed seams. Also makes explicit, in the design
doc and ADR, that function-level "single owner" sentences inside
already-covered modules (STATE.md Document Module, etc.) are deliberately
out of scope — a seam claim is about a module's boundary, not every
function inside it.

fa41bfec5c enhance(#3942): the emitted-drift ack is PR-lifetime data — move it to a commit trailer (#3954)
* test(#3942): failing-first suite for the emitted-drift ack commit trailer

Binds 37 input classes from the phase test matrix to the behavior ADR-3942
specifies, before any of it exists. Stubs return benign empty values rather
than throwing, deliberately: several rows assert that something DOES throw
(cap overflow, uncomputable commit range), and a throwing stub would turn
those green for the wrong reason and destroy the red.

The two rows that carry the design's load:

- merge-base semantics. The range is $(git merge-base base HEAD)..HEAD, not
  base..HEAD, because changedPaths comes from `git diff base...HEAD` (three
  dot). Two-dot would let the ack set and the change set disagree about which
  commits are this PR's. The fixture forks a topic branch, puts a trailer on
  each side, and asserts only the topic-side trailer is in range.

- fail-closed on an uncomputable range. With fragments a depth-1 checkout
  passes VACUOUSLY, every fragment reading as brand-new. With trailers the
  range cannot be computed at all, and returning an empty set would silently
  disarm the gate, so it must throw. The fixture builds a genuine shallow
  clone rather than simulating one.

Also covers the self-inflicted case: this change's own documentation quotes
the trailer syntax, so an example landing at the end of a commit message would
arm a live acknowledgment keyed on the literal placeholder text. Keys carrying
angle brackets or whitespace are rejected.

Authored per the phase artifacts 40-design.md and 50-test-matrix.md.
Not yet run on the remote runner — this commit exists to be tested.

Refs #3942

* chore(#3942): move the emitted-drift ack to a commit trailer

Implements ADR-3942, superseding ADR-2719 section 3 and its #2789 amendment.
Sections 1, 2 and 4-7 are retained: the conservation law is unchanged, only the
storage of its escape hatch moved off the working tree.

An acknowledgment explains one PR's ripple, and the moment that PR merges the
ripple is in the base, so it can never clear anything again. It was stored in
permanent shared state anyway, and every consequence of that mismatch had to be
built and then maintained. The chain is #2789 -> #2914 -> #3078 -> #3842 ->
#3823 -> #3875, each fix generating the next defect, ending in a scheduled
sweeper whose own first PR could not merge itself.

Added
  parseAckTrailers + renderAckTrailer (pure) and readAckTrailers (IO shell),
  reading Emitted-Drift-Ack-Hash: / Emitted-Drift-Ack-Growth: trailers over
  the merge-base range. tests/emitted-ack-trailer.test.cjs, 37 cases, written
  failing-first and confirmed red before any of this existed.

Changed
  diffEmitted takes two structurally distinct key-space maps instead of one
  shared paths map. That closes a latent defect: the spaces were separated by
  convention only, so a growth key satisfied a hash lookup by naming
  coincidence. staleAcks now reports which space a key was declared in.
  REMEDIATION teaches the trailer, per space, with its example rendered through
  renderAckTrailer so the taught grammar cannot drift from what the parser
  accepts.

Removed
  the sweep workflow, the guard-no-ack-on-next job, the standalone linter and
  its lint:ci entry, the fragment directory and its three spent fragments, the
  legacy single-file union, and the baseAck/spentAcks mechanism -- spentness is
  now structural, not computed.

Two range properties carry the design and are pinned by tests rather than
asserted: the range is merge-base scoped, matching git diff base...HEAD, so an
already-merged trailer is out of range by construction; and an uncomputable
range throws instead of reading as zero acknowledgments, which is the inverse
of the fragment guard's vacuous pass.

Three deliberate observable changes, each disclosed in the changeset: the
unread runtime field is gone, the legacy file is no longer read, and cross-space
excusal no longer works.

Ten open PRs carry fragments and will meet a modify/delete conflict. Measured
before landing and accepted deliberately; the one-line migration is in the PR
body.

Verified: lint:ci exit 0. Remote runner to follow on this exact sha.

Refs #3942

* fix(#3942): silent trailer collapse, lost coverage, and an unbounded cap

Six findings from the orthogonal review round, all fixed in place.

BLOCKER -- two trailers of the same name on one commit collapsed silently.
readAckTrailers built `separator=1d` where git needs `separator=%x1d`: the
`separator=` value inside a %(trailers:...) placeholder is itself a
pretty-format string, so the bare hex was emitted as two literal characters
and the split on \x1d never matched. Two same-name trailers therefore joined
into one value with errors empty -- the first reason absorbing the second
entry's key. Silent truncation, the exact class MAX_ACK_TRAILERS throws to
prevent. Confirmed with od -c against real git output before and after.

The failing-first matrix did not catch it because its "both spaces coexist"
row uses Hash plus Growth -- different trailer NAMES -- so the value separator
was never exercised. Two regression tests now cover same-name trailers
directly.

Coverage recovered: normalizeAckReason and INVISIBLE stayed on the live path
via parseAckTrailers but lost every test when the old suite was pruned. Back
under test against the current surface -- all six invisible codepoints
individually, whitespace collapse, trim, CRLF, and two seeded fast-check
properties. Dropping any single codepoint now fails.

MAX_ACK_TRAILERS counted raw trailers before de-duplication, so one trailer
carried forward across rebased commits counted once per commit and could throw
on a legitimate branch. Now counts distinct entries; 100 identical repeats
dedupe to one.

diffEmitted validated baseline, current and changedPaths but not the new
ackHash/ackGrowth, so a bad shape raised an unhandled TypeError instead of an
error verdict -- the same defect shape this file documents for #2778.

Docs: CONTRIBUTING and TESTING-SUITES were rewritten only in their first
sections; the later passages still taught fragments, git rm and the deleted
guard, contradicting the new text directly above them. Finished.

Also extends lint-removed-but-needed to exempt docs/adr and docs/research.
That gate fails on any docs mention of a file deleted in the same diff, which
makes it impossible to document a deletion in the PR performing it -- an ADR's
whole job is naming what it retired. Exemption is narrow and comes with a test
proving the gate still fires for a live consumer elsewhere under docs/. A
guard that cannot fail is worse than no guard. Maintainer-approved.

CONTEXT.md names the retired machinery by role rather than by filename: its
generated projection lands in docs/, which that gate does scan.

Adds docs/how-to/acknowledge-emitted-drift.md. The required docs set is
Reference and Explanation, so the task quadrant can be empty with every gate
green -- and this change has a real multi-step journey, including the fragment
migration ten open PRs now need.

lint:ci exit 0.

Refs #3942

* docs(#3942): correct the duplicate-trailer rule in CONTRIBUTING

Both axes of the code review independently flagged the same passage, without
seeing each other's output.

It claimed two declarations of the same key are always "a hard, loudly-reported
error, not a silent last-wins". That is only half true, and the missing half is
the one contributors hit: identical declarations -- same key, same reason --
dedupe silently, because a trailer legitimately survives a rebase and reappears
on every rebased commit. Failing there would red a branch for doing nothing
wrong, which is exactly why the dedup exists.

Only a same-key/different-reason pair errors, and that one is a genuine
ambiguity about which explanation holds.

As written, the paragraph told a contributor that a rebase-carried trailer
breaks the gate -- the opposite of the behavior. CONTEXT.md's parallel entry
already stated it correctly; this brings CONTRIBUTING into line.

Doc-only, root-level markdown.

* fix(#3738): antigravity global skills/agents install to ~/.gemini/config

Antigravity's machine-local discovery scans ~/.gemini/config/{skills,agents};
the configHome (~/.gemini/antigravity) is deprecated for artifacts. Declare the
ADR-1239 skills/agents 'home' override on the antigravity global layout — the
same mechanism codex uses (.agents) — and divert ~/.claude/skills/ references

Next install converges an existing antigravity install: manifest-managed
skills/gsd-*/ and agents/gsd-*.md under the configHome (a location AGY does
not scan) are removed — modified files backed up first, unmanifested and
non-gsd entries preserved — and now-empty containers retired. Global scope
only; the local .agents surface is live. Docs + inventory updated.

- bin/install.js converter gains the same ~/.claude/skills → ~/.gemini/config/
  rewrite as src (ADR-1508 dual copy must stay in sync).
- Parity-manifest walk covers home-override emit roots (extraEmitRootsFor) so
  antigravity's emitted skills/agents stay differential-visible at their new
  install root; install-tree fixture regen confirms an unchanged key set.
- skills-from-commands rule declares the antigravity converter as a
  runtime-scoped transform; one ack fragment covers the identity-classed
  workflow whose antigravity copy embeds the old skills path.
- Migration 010 checksum baseline + home-override set doc updated; existing
  tests updated to the #3738 contract (global dest, golden parity via layout
  dest, integration expectations).

* fix(#3738): tolerate an absent extra emit root on baseline-side measurement

The base tree's installer predates the home override, so <HOME>/.gemini/config
does not exist there; walk() threw ENOENT and the in-job baseline build failed.
An absent extra root is the legitimate pre-override shape — skip it.

* fix(#3738): review findings — manifest agents root, bare skills-path rewrite, guard comment

- writeManifest resolves the agents-kind home override (_kindDestDirSafe), so
  the manifest records agents at their actual install root and drift detection
  keeps working (isolated review finding 1, major).
- Converter bare forms ~/.claude/skills and $HOME/.claude/skills (no trailing
  slash) divert to ~/.gemini/config/skills instead of falling through to the
  retired configHome path (finding 2).
- real-home-guard comment updated: antigravity's global agents kind is the
  first agents-kind home override (finding 3, doc-only).
- Regression tests for both behavioral findings.

* chore(#3738): changeset fragment (pr number backfilled after PR creation)

* chore(#3738): backfill changeset PR number (3921)

* fix(#3738): sandbox HOME in tests that install antigravity global artifacts

antigravity is the first home-override runtime in the golden-parity and
skills-wrapper suites (codex is not in their runtime lists), so those tests
never needed HOME sandboxing — the real-home guard now (correctly) refuses
their un-sandboxed global installs on CI, where HOME is the passwd home.

* fix(#3738): stop the K3 sequential-sandbox env leak; sandbox L2's home-override plans

K3's two back-to-back sandboxHome calls leave HOME pointing at the first
sandbox once the after-hooks restore (each call saves the env as it found
it, so the second saves the first's sandbox as 'original'). On the windows
matrix that leaked gsd-k3-qwen-* home into the L2 property, whose
antigravity/global run then (correctly) refused via the #3712 real-home
guard — antigravity is the runtime that made L2's plan escape into
os.homedir(). K3 now manages the env with a single restore; L2 sandboxes
HOME per run, mirroring L1.

* fix(#3738): L2 property's HOME sandbox must exist on disk

The #3712 guard's sandbox exemption fails closed when identify(effectiveHome)
is 'absent' — L2 never created its configDir, so on the windows matrix (tmpdir
under the real home) the antigravity/global run refused even with HOME
sandboxed. Create the per-run sandbox dir and clean it up.

e20744eacb enhance(#3884): failure is a value — strict argv, and --pick that signals absence (#3922)
* test(#3884): failing-first coverage for strict argv and absence-signalling --pick

ADR-3473 §8.4 says failure is a value. Three families currently encode failure as
success, and this commit pins each one RED before the fix lands.

Measured on this tree, 2026-08-26:

  gsd-tools generate-slug "test" --pick nonexistent
    -> empty stdout, exit 0                                     (#3365)

  gsd-tools audit-open --pick nonexistent_field
    -> dumps the entire human-readable audit report, exit 0

  gsd-tools generate-slug "Hello World" --raw --pick bogus
    -> prints "hello-world", another field's value, exit 0

  gsd-tools query state.planned-phase 3        (positional, no --phase)
    -> exit 0; STATE.md's "Phase: 2 of 5 (Widget Support)" is overwritten to
       "Phase: null - READY TO EXECUTE" and the frontmatter gains a corrupted
       current_phase_name                                        (#3358)

tests/pick-flag.test.cjs:27 previously asserted the #3365 defect as the contract
("returns empty string for missing field", success === true). That assertion is
replaced by the required behavior rather than deleted.

The new parseNamedArgs block calls the spec-object signature that does not exist
yet, so it fails today by construction. The 11 existing behavior-lock tests are
left untouched here; they are corrected in the implementation commit.

C1/C4 assert at the consumer's output - STATE.md's bytes - per ADR-3180
Decision 4(b). A unit assertion on the parser would have passed throughout this
defect's life.

* enhance(#3884): failure is a value — strict argv, and --pick that signals absence

Implements ADR-3473 §8.4. Absence, emptiness and failure stop being interchangeable
ways to say "I could not answer".

parseNamedArgs (src/command-arg-projection.cts)
  Takes a spec object with a REQUIRED `positionals: number | 'rest'` and returns the
  hub's Result shape instead of a bare Record. Declaring the positional arity is what
  makes #3358's call site unrepresentable rather than merely detectable: an unrecognized
  flag or a token past the declared boundary is now InvalidArgs, naming the offending
  token and listing the accepted flags. The legacy positional-array call shape throws
  a TypeError — an internal invariant violation per ADR-3473 Decision 2, so a stale
  hand-written .cjs call site fails loudly instead of destructuring undefined off a
  Result. parseNamedArgsOrExit projects a failure onto the caller's error(); it is a
  projection over the one parser, not a second parser.

  Measured before, against a STATE.md with a populated phase-2 block:
    query state.planned-phase 3        (positional, no --phase)
    -> exit 0; "Phase: 2 of 5 (Widget Support)" overwritten to
       "Phase: null - READY TO EXECUTE", frontmatter gains a corrupted
       current_phase_name
  After: exit 1, `unexpected positional argument "3"`, STATE.md byte-identical.
  The flag form is unchanged and still updates STATE.md.

--pick <field> (gsd-core/bin/gsd-tools.cjs)
  extractField returns {found,value}, and the pick block no longer shares one catch
  between "output was not JSON" and "field was absent". An absent field exits 1 with
  pick_field_absent, naming the field and the keys that do exist; non-JSON output exits 1
  with pick_output_not_json instead of dumping the command's entire output. A field that
  is PRESENT with value null, '', 0 or false still prints at exit 0 — that is an answer,
  not a failure, and it is what keeps `--pick count` printing 0 on a fresh project.

  Measured before: `audit-open --pick nonexistent_field` printed the whole human-readable
  audit report at exit 0, and `generate-slug X --raw --pick bogus` printed "hello-world" —
  a different field's value, confidently, at exit 0.

  ADR-3409 Decision 7 explicitly deferred this contract fix to #3473; this is it. The
  sub-issue's "returns 0 when the count is zero OR absent" wording is superseded by the
  ADR rule it implements: zero prints 0, absence exits non-zero. Defaulting absence to 0
  would demote "could not answer" to "the answer is zero" — the hazard
  docs/how-to/resolve-unreachable-guard-findings.md already warns against.

Guard ledger (ADR-3473 Decision 6)
  scripts/lint-unreachable-guard-drift.cjs Detector A is RETIRED. Its premise — that a
  `--pick ... || echo` arm can never fire — is now false, so the shape it forbade is the
  correct idiom and keeping it would forbid the fix. Detector B (glob-consuming cat/ls,
  a nullglob mechanism this change does not touch) is retained in full, as are the shared
  scanner, the escape-marker parser and the baseline. Net: -1 detector, 0 added. The file
  is not deleted.

Call-site audit
  45 prompt-layer --pick invocations, every one a plain X=$(...) assignment — none in an
  if test, && chain, or a pipeline whose status is consumed, and no shell block in
  workflows/commands/agents/references sets -e. Of the 13 (command, field) pairs the
  prompt layer reads, 10 are always present; the 3 sometimes-absent ones each sit behind
  a prior found/existence check. No ADR-3409-class "field the command never produces"
  remains.

* fix(#3884): escape untrusted tokens in diagnostics, and cover five unpinned rows

Two review findings, both fixed here rather than recorded as limits.

1. A newline in an untrusted token forged a second stderr line.

   Before, plain-text mode:
     $ gsd-tools query state.planned-phase $'foo\nError: forged second line'
     Error: unexpected positional argument "foo
     Error: forged second line"

   After:
     Error: unexpected positional argument "foo\nError: forged second line"

   --json-errors mode was never affected — io.error runs that payload through
   JSON.stringify. Plain-text mode writes 'Error: ' + message verbatim, and the
   three new InvalidArgs reasons plus the two new --pick diagnostics all
   interpolate a token that comes straight from argv.

   Fixed with ONE shared helper, formatDiagnosticToken (src/io.cts), applied at
   every interpolation site — not a copy per site. It is deliberately NOT
   applied inside error() itself: several callers in this tree emit intentional
   multi-line diagnostics, and escaping newlines there would mangle them.

   The available-top-level-keys list needed the same treatment for a reason the
   review did not anticipate: `frontmatter get <file>` reads an ARBITRARY user
   document and echoes that document's own keys into the diagnostic. Verified
   reachable — a frontmatter key containing a newline reaches the key list — so
   formatKeyForDiagnosticList is guarding a live path, not a hypothetical one.
   Ordinary keys still render plain and unquoted; a fix that merely dropped the
   key would also have passed a "one line" assertion, so the test pins the
   escaped key's presence too.

2. Five behavior-table rows were implemented but nothing pinned them:
   B7  a dotted path that dies partway
   B9  bracket syntax on a non-array
   B10 a negative array index, in and out of range
   B14 a JSON root that is not an object
   B17 an @file: payload over 50KB

   B17 is the load-bearing one. output() writes @file:<path> instead of inline
   JSON past 50000 characters, and --pick resolves that BEFORE parsing; with no
   test, a future reordering of those two steps turns every large result into a
   false pick_output_not_json. The fixture seeds 1200 phase directories and
   measures the payload at 62474 characters, asserting the spill actually
   happened rather than assuming it.

* fix(#3884): correct the strict-argv surface against a full verification run

The first full run came back with 90 failures across 12 files, none in the new
tests. They were the argv surface telling me what it actually is. Ten root
causes; each classified before anything was changed.

I over-implemented, and that is reverted.

  ADR-3473 §8.4 says parseNamedArgs rejects "unrecognized and positional
  tokens". It says nothing about a value flag whose value is missing. Making
  that an error was my design decision, not the rule, and it broke a
  deliberately recorded contract: `--prd` with no value resolving to null
  (tests/init.test.cjs emptyPrdValueIsFalsyAndTreatedAsAbsent, row B5;
  tests/section-manifest-init-facts.test.cjs "flag-shaped value"). The
  "requires a value" branch is deleted outright rather than kept behind an
  option — an unused strictness mode is speculative generality. Unknown-flag
  and unexpected-positional rejection, which is what §8.4 actually mandates,
  is unchanged.

--wave needed a third flag kind the original design did not anticipate.

  `--wave N` is documented (commands/gsd/execute-phase.md:4,48) and the
  shipped workflow reconstructs and passes it (execute-phase.md:84), while
  #2932 records token-PRESENCE semantics: the CLI cares only that the flag
  appeared, and the value belongs to the workflow layer. That is neither a
  boolean flag nor a value flag, so `optionalValueFlags` now exists —
  presence-only in `data`, and the validation cursor consumes a following
  non-flag token so it is not reported as a stray positional. Every other
  declared boolean flag was checked against every argument-hint and prose
  usage in commands/, workflows/, agents/ and docs/; `--wave` is the only one
  of this shape.

Five tests were pinning forms that never worked.

  tests/adr857-core-without-capabilities.test.cjs passed
  `init plan-phase --phase 01-stub`, but the documented form is positional
  (docs/CLI-TOOLS.md:776) and the handler reads args[2] — which for that form
  is the literal string "--phase". Measured on the pre-fix build against a
  real .planning/phases/01-stub/ directory:

    init plan-phase 01-stub          -> phase_found=true
    init plan-phase --phase 01-stub  -> phase_found=false

  The test asserted only exit 0 and key presence, so it had been green while
  proving nothing about phase resolution. Corrected to the documented form and
  strengthened to assert phase_found === true. Same class in state.test.cjs
  (`--plan-count`, a flag that does not exist; the real one is `--plans`),
  milestone-archive.test.cjs (`init new-milestone --json`, silently ignored),
  and concurrency-safety.test.cjs (a bare positional field name whose
  OR-assertion passed because a whole-document dump happens to contain the
  substring it looked for).

Six handlers had no argv validation at all — the same #3358 shape this phase
exists to close, found while fixing the rest: init verify-work / phase-op /
review / todos / remove-workspace read args[2] with nothing checking the rest,
and validate health read --repair/--backfill through a bare args.includes()
scan that bypassed the parser entirely. All now go through the seam, so the
flag has one owner.

tests/init-debug.test.cjs rows C4/C5 asserted that an unrecognized flag must
NOT fail. That is the behavior §8.4 removes, and Decision 8 says a caller's
local expectation does not override §8, so they are inverted and renamed —
a test still called "ignores an unrecognized flag" while asserting rejection
would be its own defect. Row C6's point is its PWNED canary; that assertion is
kept verbatim and only its exit-status expectation changed, because the
hostile token is now rejected rather than absorbed.

The blast-radius estimate in 40-design.md is corrected rather than quietly
left wrong. get_impact reported MEDIUM / 8 symbols upstream, and that was
accurate for what the graph can see — parseNamedArgs's callers. It cannot see
that those callers' handlers accept argv shapes wider than the code reading
args[2] suggests, which is where the real surface was.

* fix(#3884): withdraw the validate-health tightening, finish the A2/A3 revert

Second full run: 46 failures, down from 90. Four causes, two of them mine.

Reverted `validate health` entirely — it was scope creep, and it broke a real flag.

  ~30 of the 46 read `unknown flag "--json"; accepted: --repair, --backfill`.
  The previous commit routed `validate health` through the parser on the
  reasoning that a flag should have one owner. That was wrong twice over:
  §8.4 names parseNamedArgs and count queries, and `validate health` was never
  a parseNamedArgs call site — it read its flags, just not through the parser,
  so it had no silent-drop defect to fix. Tightening it omitted `--json`, which
  the health-diagnostic suites use heavily. The handler is now byte-for-behaviour
  back to its pre-branch form. `validate context` stays converted: it genuinely
  was a call site, and its `--json` is now declared rather than read by a second
  `args.includes` scan.

  The five handlers that had NO validation at all — init verify-work / phase-op /
  review / todos / remove-workspace — stay fixed. Those read args[2] with nothing
  checking the rest, which is the #3358 shape this phase owns.

Finished the A2/A3 revert. Three tests still encoded the deleted
"a value flag with a missing value is an error" rule, including one added by the
previous commit for that rule. All three now assert the reverted null contract,
and the ones whose titles said "rejected" are renamed — a test named for a
contract it no longer asserts is its own defect.

`--wave=` and `--wave --weird` are correctly rejected. Neither is documented in
commands/gsd/execute-phase.md, gsd-core/workflows/execute-phase.md or docs/, and
neither is emitted by the shipped prompt layer, so both are unrecognized tokens
that §8.4 mandates rejecting. `doesNotConsumeFollowingFlagAsWaveValue` keeps the
property it exists for — asserted directly now, at the parser, that `--wave` does
not swallow a following flag as its value — and only its exit-status expectation
changed.

A contradiction inside this branch, surfaced by the audit and resolved the safe way.

  Two pre-existing #3573 tests call `state begin-phase '2'` and
  `state planned-phase '2'` with a bare positional, relying on the old permissive
  parser to ignore it. This branch's own #3358 regression test requires that exact
  argv to be REJECTED. The two are mutually exclusive.

  Widening the router to accept a bare positional — mirroring complete-phase —
  would have silently re-opened #3358, and was verified to do exactly that: with
  the widened router, `query state.planned-phase 3` returned exit 0 and wrote
  current_phase_name again. It is reverted. docs/CLI-TOOLS.md:116 and
  docs/COMMANDS.md:2192 document only the `--phase N` form for both verbs, so the
  two #3573 tests move to it. Their assertions were never about the call shape —
  only that total_phases survives the resync — and both still pass.

  complete-phase is untouched: its bare positional IS documented, and it keeps the
  dynamic boundary and the negative-space note that record why.

The audit that produced this is in the PR body: for every handler whose declaration
changed, the flags it reads anywhere in its body, the flags the shipped surface
documents, and the shapes the suite passes, compared. The `--json` miss was a
pattern, not an accident — declaring a handler's flags from its parseNamedArgs call
alone misses whatever it reads elsewhere.

878f25025c enhance(#3905): the exit-code registry — one number, one meaning, enforced at build (#3920)
* feat(#3905): the exit-code registry — one number, one meaning, enforced at build

A generated registry replaces locally-invented exit codes. Every entry records code, name, meaning, owning module and the decision that authorized it. The generator refuses to build a table where two entries claim one code, two claim one name, a code falls in a range Node or the shell reserves, 2 is claimed by anything but the hook adapter, or an allocation carries no justification. exitCodeFor is pure and total: it throws rather than returning undefined, including for prototype-chain names.

Inert by design — nothing emits a registered code until #3906. Every registered code is non-zero, asserted over the whole table, so a caller testing for failure behaves identically for pass and trips for everything else.

* feat(#3905): make the registry generator's failures machine-readable

Adds a --json mode carrying {ok, reason, context, detail}, where context is a typed payload naming the specifics the prose embedded - which code collided and under which names, which band rejected a code, which field was missing. The tests now assert on that structure instead of regex-matching the generator's stderr, which CONTRIBUTING prohibits, and the CONTEXT.md glossary gains the entry the issue's scope requires.

* test(#3905): refresh the install-tree fixtures for the new declaration

The registry declaration ships in the install tree, so all 19 golden fixtures needed regenerating. Caught by the remote matrix, not by lint:ci - the install-tree goldens are verified by a test rather than a lint, so a newly shipped file clears every local gate and fails only under the suite.

7e9d33c378 enhance(#3915): stryker on the official tap runner, 29m to 12m on the critical path (#3919)
* enhance(#3915): stryker on the official tap runner, per-test coverage

The 'command' runner is the one runner Stryker excludes from coverage
analysis, which forced coverageAnalysis:'off' and made mutation cost
strictly linear in (mutants x whole-shard test time). The frontmatter
shard measured 1751s against 212s for the next slowest.

Swap to @stryker-mutator/tap-runner (official plugin, peer-pinned to the
@stryker-mutator/core@9.6.1 already installed) and turn coverage analysis
on, so Stryker re-runs only the test files that cover each mutated line.

Per-shard injection moves from a MUTATION_TEST_CMD command string to
MUTATION_TEST_FILES, read by a new fail-closed resolveMutationTestFiles()
that mirrors resolveMutationBreak. It stays derived from
scripts/mutation-matrix.cjs and now has a single owner: the union moves
behind allCoveredTests() and stryker.config.mjs no longer imports COVERED.
The resolver existence-checks every entry, because the tap runner resolves
tap.testFiles with glob() and a non-matching pattern yields an empty list
silently - a fast, confident, meaningless run.

tap.forceBail is off by measurement, not preference: a structural AST
audit found 3 of 26 shard test files spawn subprocesses, and bail fires on
every killed mutant, so leaving it on would kill processes mid-spawnSync
and orphan their children.

The matrix 'isolation' field is removed - per-file process isolation is
inherent to the tap runner, so the field had no consumer left.

Score arithmetic is unchanged and now pinned: mutationScore counts
NoCoverage in the same denominator as Survived, which both Stryker's
thresholds.break and check-mutation-score-ratchet.cjs read. A new
non-vacuity test proves it diverges from mutationScoreBasedOnCoveredCode,
so the gate cannot be quietly swapped to the field that would make every
floor trivially satisfiable.

Refs #3915

* fix(#3915): enforce the resolver's documented containment contract

Review findings, all fixed in place.

resolveMutationTestFiles claimed to verify each entry exists 'relative to
the repo root' but used a bare fs.existsSync(path.join(...)), which
accepts an existing DIRECTORY and lets ../ segments escape the root
(path.join('/repo/root','../../etc/passwd') resolves to /etc/passwd).
Not reachable from PR content - the value only ever comes from the static
COVERED registry via CI env - but a fail-closed contract that overstates
its own guarantee is a defect in the contract. Each entry is now resolved,
rejected if path.relative puts it outside the root, and required to be a
regular file. Three hostile-input tests added; the original missing-file
wording is preserved so the existing assertion still binds.

Also: removed a stale buildResult comment still naming the isolation
field this branch deleted; hoisted one top-level path require in place of
three inline ones; de-duplicated the derived-test-list expression in the
tests to a single const, deliberately still re-derived from COVERED
rather than calling allCoveredTests() so the assertion cannot become a
tautology; tightened the workflow-parity assertion to exact equality;
changed the tap-runner range from an exact 9.6.1 to ^9.6.1 so it tracks
the caret-ranged core its peerDependency pins exactly.

Regenerated examples/dynamic-context-management/CONTEXT-INDEX.json, which
the earlier CONTEXT.md edit left stale - lint:ci was red on
lint-example-parser-parity until it was refreshed.

* test(#3915): kill model-catalog survivors, set frontmatter budget from measurement

From mutation run 33026833181 (all 13 shards, dispatched on this branch before any PR).

WALL TIME: frontmatter measured 713s (11m53s) vs 1751s (29m11s) on the command runner, a 59% cut. timeoutMinutes 60 -> 20 (1.68x measured). Not deleted outright: the shared 15-minute default would leave only 21% headroom, and this module's mutant count grew 1.8x in one change.

MODEL-CATALOG: came back 57.91 against its floor of 58. Diagnosed from the report JSON, not assumed - all 24 of its new RuntimeError mutants are in the load-time catalog bootstrap, so mutating them makes the module throw at require. Under node --test that is a failed test file (Killed); under the tap runner the process dies before emitting TAP, which Stryker classifies RuntimeError and excludes from the denominator. Add them back as killed and the shard is 248/416 = 59.62, the pre-change number exactly. Detection did not regress, classification changed.

The floor is NOT lowered to absorb that. 11 new behavioural tests target ~42 genuinely surviving mutants: exact Set equality on the EFFORT_RENDERING/EFFORT_ARGV supported sets, an exact-string table render that makes the column-width arithmetic observable (padEnd never truncates, so the old substring assertion could not see a too-small width), clampEffortForHost's full null matrix plus a spoofed-toString host, and a prototype-pollution guard driven through Object.fromEntries.

Mutants judged equivalent were skipped rather than papered over; reasoning is in the phase artifacts. All 15 new assertions verified against unmutated code. lint:ci exit 0.

Refs #3915

* test(#3915): ratchet model-catalog's floor to 74 on measured 75.26%

CI run 33029755081 measured model-catalog at 75.26% (295 killed / 49 survived / 48 no-coverage / 24 runtime-error, totalValid 392), so check-mutation-score-ratchet.cjs correctly failed the shard for unclaimed headroom: 17.26 points above the declared floor of 58, well past the 5-point slack.

Floor raised 58 -> 74 (floor(75.26)-1, this file's documented convention), with RATCHET_BASELINE updated in the same diff as the equality assertion requires.

Worth recording why the number moved this far. The shard first came back at 57.91 under the tap runner and the temptation was to lower the floor to match. The drop was not a regression: all 24 of its RuntimeError mutants sit in the load-time catalog bootstrap, and adding them back as killed reproduces 248/416 = 59.62, the pre-swap figure exactly. Rather than absorb a reporting artifact by weakening the gate, 11 behavioural tests went after the genuinely surviving mutants and killed 68 of them - carrying the module from 59.62 past its old ceiling to 75.26, within reach of the ADR-456 target of 80.

The #3007 measurement is kept as clearly-labelled prior context rather than deleted, so the entry does not read as carrying two current numbers.

6b7df61938 enhance(#3881): one YAML parser — vendored js-yaml replaces the hand-rolled dialect (#3888)
* docs(#3881): answer §8.1's open question and correct three wrong premises

ADR-3473 §8.1 carries a blocking open question with a forcing function: it must
be answered before any implementation PR for the rule opens. Answered here as (a),
a string-coercing adapter, with the measurement that settles it.

The sequencing note bet that §8.8's schema would make (b) tractable. Measured
against merged reality it does not: only 33 of extractFrontmatter's 78 non-test
call sites read STATE.md, and two of the five compensating mechanisms §8.1 lists
survive real types, leaving ~31 lines across 3 call sites as the actual prize.

Also corrects three claims verified false while answering it. §8.1's justifying
sentence names #3349 and #3360 as defects a real parser would fix; both are
already fixed on next, confirmed by executing the compiled parser rather than
reading it. The guard roster calls lint-frontmatter-scalar-broad-grep.cjs an
expected casualty of this rule, but it guards shell grep idioms in workflow bash
fences and never touches our parser. The same roster calls lint-vendored-deps.cjs
reusable as-is; it is hardcoded to re2js throughout.

The last two were caught by applying the rule this amendment records -- a factual
claim in this ADR is a hypothesis until the implementing phase executes it -- on
its first use.

* docs(#3881): record that §8.1's fork is ill-posed and (a) is not implementable

An adversarial pass on the Phase 4 design established by execution that
extractFrontmatter is not a YAML parser but a line-oriented scanner whose output
is a function of raw source text. Four spellings of the same value collapse to
one js-yaml tree but produce four distinct legacy strings, one of them mangled.
No adapter over a tree can choose among outputs the tree does not distinguish,
so fork (a) -- keep a string-coercing adapter so the existing contract holds --
cannot be built. For any document with a non-scalar value, (a) collapses into
(b); about 26 percent of frontmatter-carrying documents have one.

Also records three design defects and one new attack surface, all confirmed by
execution: catching a parse failure and returning {} would delete the frontmatter
block on the next write at eight call sites that conflate empty with unparseable;
an empty value yields null where legacy yields {}, and reconstructFrontmatter
omits null-valued keys, so the shipped state template's empty progress key would
vanish; the #1882 truncation probe is parseYamlRegion itself rather than a
pre-parse heuristic, so it cannot both stay unchanged and survive that deletion;
and FAILSAFE_SCHEMA still resolves aliases, expanding seven lines to 22.8 MB.

The rule is not deferred. The measurement is the deliverable and the re-scoping
is recorded as an open question with a forcing function, per section 8's own rule.

* test(#3881): failing-first rows for block scalars, unicode keys and the missing #3594 matrix

Creates tests/feat-3594-parser-adversarial-frontmatter.test.cjs, the file the fixture README instructs contributors to register fixtures in but which never existed.

Section C: table-driven ownership check over tests/fixtures/adversarial/frontmatter/ so a fixture with no matrix entry fails loudly; six existing fixtures (duplicate-keys, crlf-mixed, unclosed-block, unicode-keys-and-values, null-byte-value, huge-bounded) each get the invariant its README states.

B1 blockScalarValueIsNotTheBlockIndicator: parsing commands/gsd/add-tests.md must give argument-instructions the instruction text, not the literal '|'. RED today.

B2 blockScalarDoesNotInventATopLevelKey: same parse must not produce a top-level Example key scraped from inside the block body. RED today.

B3 unicodeKeyRoundTripsAsIs: the 相 key in unicode-keys-and-values.md must survive parsing; today it is silently dropped. RED today.

* chore(#3881): vendor js-yaml and generalize the vendored-deps guard to a manifest

Packaging step for ADR-3473 §8.1: makes js-yaml available to gsd-core/bin/** without promoting it out of devDependencies (promoting broke every installed tree, #3496).

gsd-core/bin/lib/vendor/js-yaml.cjs is a verbatim copy of node_modules/js-yaml/dist/js-yaml.js (the self-contained UMD dist bundle, not index.js), exposing load/dump/FAILSAFE_SCHEMA/YAMLException with zero require() calls of its own.

src/vendor/js-yaml.d.cts is hand-authored, not copied, because js-yaml ships no upstream .d.ts and @types/js-yaml is not installed. It is deliberately narrow, declaring only the four symbols in use, so anchors/aliases/custom types/loadAll are unreachable from typed code -- a compile-time enforcement of ADR-3473 §8.1's refusal to expand alias resolution for security reasons. Because it has no upstream counterpart it is excluded from the byte-compare.

scripts/lint-vendored-deps.cjs is refactored from a script hardcoded to re2js into a table-driven VENDORED manifest (one row per package: upstream/vendored .cjs paths, optional .d.cts paths, twin kind upstream-verbatim vs hand-authored) so a second vendored package does not require a second hardcoded check block, per ADR-3473 §8.3 'one implementation per rule'. The four existing re2js checks (vendored .cjs vs node_modules, vendored .d.cts vs node_modules, src/vendor twin vs bin-side twin, devDependency version pin vs installed version) are preserved unchanged; verified pass/fail identical before and after the refactor, and the guard's ability to fail was re-proven with a deliberate one-byte append to both re2js.cjs and js-yaml.cjs, then restored.

docs/INVENTORY.md and docs/INVENTORY-MANIFEST.json (via gen-inventory-manifest.cjs --write, run after build:lib) register vendor/js-yaml.cjs. gsd-core/bin/lib/vendor/README.md documents both vendored packages and the two twin kinds.

* feat(#3881): parse .planning frontmatter with the vendored js-yaml

ADR-3473 §8.1: extractFrontmatter's read path is no longer a hand-rolled
line scanner. parseYamlRegion, escapeDoubleQuoted, unescapeDoubleQuoted and
parseQuotedScalar are deleted (not patched); parsing now goes through the
vendored js-yaml (./vendor/js-yaml.cjs) under { schema: FAILSAFE_SCHEMA,
json: true }. Everything js-yaml does not do is layered on top, in one
place, carrying the seven design-doc consequences:

1. Empty value: a null js-yaml value is coerced to {} (matching legacy's
   own empty-value contract) so reconstructFrontmatter — which omits
   null-valued keys — still round-trips a bare `key:` line instead of
   deleting it. Verified live: progress: with no value survives
   parse -> reconstruct -> re-parse.

2. Unparseable no longer collapses to a bare {}: a new FRONTMATTER_UNPARSEABLE
   Symbol (exported), keyed exactly like the existing #3257 FULL_LINE_COMMENTS
   channel, is carried on the {} returned for malformed/refused YAML. Invisible
   to Object.keys/entries/JSON.stringify/for-in, so the 70 call sites that
   never inspect it are unaffected; wiring the 8 hasFrontmatter sites to
   consult it is a separate change, not done here.

3. Non-scalar object-list items (the four spellings of `- test: a b` that
   js-yaml collapses into one tree shape) are rendered as a canonical
   `key: value[, key2: value2]` string per item, keeping the existing
   array-of-strings value SHAPE. A full corpus differential over all 1702
   tracked markdown files found 11 residual divergences from the legacy
   parser (enumerated in the PR/report), most of them the parser now being
   MORE correct (a dropped quoted top-level key, the block-scalar/phantom-key
   defect, a dropped Unicode key).

4. The #1882 truncation probe still runs the one real parser, but derives
   its key count from js-yaml's own thrown error and mark.line when the
   whole region doesn't parse cleanly (the dominant real truncation shape:
   fence opened, well-formed keys, no closing fence). Verified against both
   the clean-parse and the exception-fallback path.

5. The #3257 comment channel now attributes each pending column-0 comment
   against js-yaml's own parsed top-level key list (matched by literal key
   text, in document order) instead of the legacy ASCII-only key regex, so
   a comment above a Unicode key attaches correctly.

6. Anchors, aliases and merge keys are refused outright (a raw-text
   pre-scan, since FAILSAFE_SCHEMA still resolves them) — corpus occurrences
   today: zero. A 7-line billion-laughs fixture is verified refused rather
   than expanded.

7. A literal U+0000 is swapped for a private-use sentinel before the parse
   and restored in every resulting string afterward, since js-yaml rejects
   NUL unconditionally under every schema.

escapeDoubleQuoted is deleted and reimplemented via js-yaml's dump()
(forced double-quoted style), with control-char hex escapes lowercased to
keep serialized output byte-stable (#1779 emitted lowercase); it keeps its
exported name and signature for its two other call sites (commands.cts,
runtime-artifact-conversion.cts), which need no change.

frontmatterDeepEqual, the comment channel, sliceTopLevelFrontmatterSegments,
regenerateFrontmatterKey's guard, noOpObjectListSetError and
parseMustHavesBlock are all unchanged — retiring them is fork (b) and is
not this phase.

Refs #3881

* fix(#3881): quote template placeholders and preserve unparseable frontmatter

SECURITY.md/UI-SPEC.md/VALIDATION.md wrote frontmatter placeholders as
bare {N}/{phase-slug}/{date}, which is valid YAML flow-mapping syntax
under the vendored js-yaml parser, not the literal placeholder text
intended. Quote them so they parse as strings.

Wire the FRONTMATTER_UNPARSEABLE Symbol (exported but unused) at the
8 call sites in state.cts/state-transition.cts that compute
hasFrontmatter via Object.keys(extractFrontmatter(...)).length > 0 and
reassemble the document without a frontmatter block when false. That
check conflated 'no frontmatter' with 'unparseable frontmatter' (both
parse to {}), so a document with a merge-conflict marker or refused
alias in its frontmatter had that block silently dropped on write.
Each site now preserves the exact raw bytes stripFrontmatter removed
when the marker is set, leaving the genuinely-empty case unchanged.

frontmatter block independently, so the marker binds at the transform layer.

* docs(#3881): record the semantic-migration decision and the counted guard ledger

The maintainer chose the full semantic migration over splitting the rule into
its own epic or patching the scanner, so section 8.1 is answered as "the fork
was ill-posed and the migration is semantic" rather than as (a) or (b).

Also replaces the pre-implementation guess that this phase would shrink the
guard surface with the counted result: excluding vendored third-party lines the
hand-maintained surface is net +307, and frontmatter.cts grew by 68 lines
despite four functions being deleted, because the compatibility layer over
js-yaml is larger than the scanner it replaced. Section 8.1's stated benefit is
therefore not delivered as written; what improved is the kind of code
maintained, not the amount. Decision 6 requires recording that rather than
netting it away.

Refs #3881

* fix(#3881): refuse anchors structurally and fold in review findings

ADR-3473 §8.1 review findings, addressed inline:

Finding 1 (BLOCKER): refuseAnchorsAndAliases was a raw-line regex that matched
only the bare-key spelling (key: &x). A quoted key ("a": &x), a flow mapping
({b: &x}) and a flow sequence ([&x, *x]) all define/use the SAME anchor
mechanics while never matching that line shape, so the exact expansion the
guard exists to stop went straight through unrefused (a 303-byte quoted-key
bomb expanded to ~35.8MB). Replaced with js-yaml's own `load` `listener`
callback, which reports `state.anchor` for every event belonging to an
anchored node in every spelling, and throws from inside the callback to abort
before any expansion (~1-2ms vs full expand-then-discard). A merge key with
an alias is still refused (merge always requires a previously anchored node,
so the alias itself trips the listener); a bare merge key with NO alias is no
longer separately refused, documented as intentional: FAILSAFE_SCHEMA never
resolves `!!merge`, so it carries no expansion risk. Table-driven tests added
for all four bypass spellings + merge key, plus a quoted-key-spelled
billion-laughs fixture registered in the adversarial matrix and README.

Finding 2: src/vendor/js-yaml.d.cts's docblock falsely claimed anchors/
aliases were "simply UNREACHABLE from typed code" through the twin. Corrected
to state the truth: anchor/alias resolution is document-level `load`
mechanics reachable through exactly the declared surface, and refusal is
enforced at RUNTIME (Finding 1's listener), not by the type surface.

Finding 3 (MAJOR): the null-byte sentinel (U+E000) round-trip was
non-injective — restoreNullBytesDeep rewrote every U+E000 in the parsed tree
back to NUL, including one the document author legitimately wrote, silently
corrupting it. Now refuses outright whenever the raw region already contains
U+E000 (consistent with the existing anchor/merge-key refusal path), making
the substitution provably injective. Tests added for a real NUL alone
(preserved), a pre-existing U+E000 alone (refused, not corrupted), and both
together (refused, not merged into one byte).

Finding 4 (MAJOR): scripts/lint-vendored-deps.cjs's `srcTwin` field was dead
for a hand-authored row (only read inside the upstream-verbatim branch) —
exactly how Finding 2's stale docblock drifted unnoticed. Added
checkHandAuthoredTwin: every value-level export the twin DECLARES must be an
actual own property of the vendored runtime module at require-time. Tests
added, including a sensor that a declared-but-nonexistent export IS caught.

Finding 5: the existingFm/hasFrontmatter/stripFrontmatter/fmPrefix/
unparseableFm/reassemble preamble, copy-pasted at 7 sites in
state-transition.cts plus a sixth hand-inlined copy in state.cts's
cmdStateCompletePhase, is now one exported helper
(beginFrontmatterReassembly) every site routes through, including the
hand-inlined one. Three call sites (beginPhaseCore, patchCore, updateCore)
keep a literal `body = stripFrontmatter(content)` assignment alongside the
helper call so scripts/lint-state-write-path-drift.cjs's single-hop backward
scan (which does not chase aliases) still sees the strip; stripFrontmatter is
pure/idempotent so the extra call changes nothing observable.

Finding 6: corrected the frontmatter.cts docblock's stale "wiring is a
separate change" claim (the 8 call sites are wired on this branch) and the
changeset's backlink from (#3473) to (#3881).

Finding 7: fixed the lint:ci failures blocking the gate — an
@typescript-eslint/only-throw-error violation from throwing a bare Symbol as
the anchor-detected signal (now a real Error subclass), unused-var warnings
left over from the Finding 5 refactor, a lint-test-file-count cap exceeded by
two migration-specific test files (allowlisted with justification), and the
lint-state-write-path-drift false positive from Finding 5's helper (fixed
above). tests/frontmatter-golden-parity.test.cjs:117's execFileSync already
carried an explicit timeout; no change was needed there.

Golden fixture: added a golden entry for the new
anchor-alias-bomb-quoted.md fixture ({} — matches what the legacy line
scanner would also produce, since it independently dropped every quoted
top-level key). No other corpus document diverges: real .planning/ documents
carry zero anchors/aliases/merge keys/U+E000 today.

Refs #3881

* fix(#3881): fold in second-round review findings

Finding 1 (BLOCKER): tests/frontmatter.test.cjs pinned the pre-migration
ASCII-only key regex for the Unicode fixture; updated to require the 相
key's value now that js-yaml has no such restriction. Audited the rest of
the file for other pre-migration pins (block scalars, quoted keys,
flattened values, empty values, duplicate keys, unclosed blocks, null
bytes) by execution against real fixtures; found none regressed.

Finding 2: parseYamlRegion and escapeDoubleQuoted renamed to
parseGuardedYamlRegion and escapeDoubleQuotedScalar in src/frontmatter.cts
so no function still answers to the deleted hand-rolled scanner's name
(ADR-3473 §8.1 "deleted, not patched"). escapeDoubleQuotedScalar's three
external call sites (src/commands.cts, src/runtime-artifact-conversion.cts)
updated in the same change — a mechanical rename, not an ADR-amendment
matter.

Finding 3 (BLOCKER): fixed a real crash and a silent data-loss bug found
by execution. A top-level key named constructor/__proto__/toString/
valueOf/hasOwnProperty crashed reconstructFrontmatter (bracket read
resolving an inherited Object.prototype member); a key literally named
__proto__ was silently DROPPED entirely (bracket assignment on an
ordinary {} invoked the inherited __proto__ setter instead of creating a
data property). Fixed by building every parsed Frontmatter object with
Object.create(null), and replacing an `in` check with hasOwnProperty.call
in propagateCommentChannel. Added round-trip tests for all five hostile
keys, each with its own leading comment.

Finding 4 (MAJOR): escapeDoubleQuotedScalar's docstring falsely claimed
full byte-stability across the migration. Verified by execution: BEL/NUL/
NEL/NBSP/LS/PS/BOM now emit YAML-named escapes instead of the old hex/raw-
literal forms. Proved round-trip equivalence (each escape re-parses to the
exact source codepoint) and corrected the docstring. Found and fixed a
related real defect while verifying: a lone UTF-16 surrogate was emitted
BARE (scalarNeedsDoubleQuoting didn't trigger), producing genuinely
unparseable YAML that silently collapsed to {} on re-read — extended
scalarNeedsDoubleQuoting to route surrogates through the quoted+escaped
path.

Finding 5 (MAJOR): countKeysBeforeTruncation went silent on 4 real
truncation shapes (unquoted colon, open flow collection, mis-indented
sibling key, refused anchor). Root cause: the mark-based prefix recovery
excluded the very line whose key needed counting, and a mark-less refusal
never entered the recovery branch at all. Fixed by taking the max of two
lower bounds: the longest parser-verified line-prefix, and a raw-text
count of key-shaped lines (reusing the same key-shape pattern this file
already uses for isFrontmatterShaped). Extended test-matrix row A5
table-driven over all 4 regressed shapes.

Finding 6: the design doc's claim that no test owned the #3594 adversarial
fixture corpus was false — consolidation epic #1969 had already folded it
into tests/frontmatter.test.cjs. An earlier commit on this branch
re-created a standalone duplicate under that false premise; folded its
genuinely-new coverage (fixture-ownership check, anchor-bomb fixtures,
block-scalar B1/B2 rows) into frontmatter.test.cjs and deleted the
duplicate file. Corrected the false claims in 40-design.md §3.3.1 and the
ADR's §8.1 note, including the roadmap-sibling claim (no such file exists).

Finding 7: the golden serializer sorted object keys, making it structurally
blind to the key-order-parity invariant ADR-3473 §8.1 actually claims.
Made it order-preserving and regenerated the golden fixture from a
standalone compile of the legacy (pre-#3881) parser at ddde001af; the
current parser matches it with zero undocumented divergences, confirming
key-order parity genuinely holds. Extended row A2 table-driven across 6 of
the remaining 7 transitionCore kinds (all pass) plus documented, by
execution, a newly-discovered 8th-site regression: state.cts's
cmdStateCompletePhase calls the same preservation helper but its result is
clobbered by a later unconditional resync — filed as a distinct finding
rather than fixed here (touches syncAndPreserveStateMd, outside this
change's verified scope).

Refs #3881

* fix(#3881): preserve unparseable frontmatter through the CLI write path

Characterization (executed, before/after shown): case (b), not (a). The
frontmatter FENCE survives — `state complete-phase` on a conflict-marked
STATE.md returns success and a well-formed, freshly-derived frontmatter
block, not a document with no frontmatter at all. But the block's actual
content (the merge-conflict markers, and with them any signal to a human
that the document was in conflict) is silently discarded and replaced.

Root cause was two clobber sites, not one:

1. syncStateFrontmatter (src/state.cts) re-parses the already-preserved
   `transformedContent` from readModifyWriteStateMd, finds {} + the
   FRONTMATTER_UNPARSEABLE marker, and unconditionally rebuilt a fresh
   frontmatter block from the body anyway.
2. Even after (1) is fixed, applyPostSyncPreservation's own
   postFm/applyStatePreservation/authoritativeFm-reassertion machinery
   re-extracts frontmatter from syncedContent, restores curated fields
   from the pre-write snapshot, and reconstructs a NEW block again —
   confirmed live via `state begin-phase`, which still lost the markers
   after fixing (1) alone.

Both are now guarded by the same predicate (isUnparseableFrontmatter,
checking FRONTMATTER_UNPARSEABLE): when the ORIGINAL frontmatter did not
parse and the caller is not on ADR-3408 §8.3's closed "body wins" list,
both functions return their input content unchanged rather than
re-deriving over it. The closed list (cmdStateSync #905,
/gsd-health --repair's REGENERATE_STATE, both routed only through
writeStateMd, which never reaches applyPostSyncPreservation and passes
sanctionedPermanentEmptyFallback=true to syncStateFrontmatter) is
untouched — neither widened nor narrowed; verified by execution that
`state sync` still overwrites the conflict-marked block exactly as before.

Other verbs sharing the same readModifyWriteStateMd path were checked and
were equally affected before this fix: state update, query state.patch,
and state begin-phase all lost the conflict markers (RED, shown by
execution), and all three now preserve them (GREEN). Covered table-driven
in tests/feat-3881-yaml-parser-consequences.test.cjs's new A2b describe
block, which drives the real CLI verbs via runGsdTools — not just the pure
transitionCore layer the earlier A2 rows exercised — plus a control
asserting state sync's body-wins contract is unchanged.

Refs #3881

* fix(#3881): restore the parse surface's prototype and fix remote-runner failures

Root cause of the bulk of the 88 remote-runner failures: extractFrontmatter/parseGuardedYamlRegion handed back Object.create(null) trees for prototype-pollution safety, but assert.deepStrictEqual compares prototypes, so every assertion against a plain object literal failed (57 frontmatter.unit.test.cjs + 5 frontmatter.test.cjs + others). Fixed by keeping the internal construction null-prototype (unchanged) and converting to a plain-prototype tree via Object.defineProperty (never bracket assignment, so __proto__/constructor/toString keys stay safe) at the parseGuardedYamlRegion/unparseableResult return boundary only; the internal FULL_LINE_COMMENTS Symbol channel is copied by reference, not recursed, so its own __proto__-safety is untouched.

Per-class fixes: (1) bomAcrossArtifactTypes was the same prototype bug, no separate code change needed. (2) frontmatter-cli #1660: added objectListFieldWouldLoseData, a broader lossy-field detector alongside the existing byte-identical noOpObjectListSetError -- js-yaml's flattenObjectListItem now correctly includes every sub-key of an object-list item (a real bug fix over the legacy scanner, which silently dropped every field but the first), so a set that drops that now-included data is no longer byte-identical to the original and needs its own guard. (3) uat.test.cjs: updated the pinned expectation for the human_verification quote-stripping artifact -- js-yaml resolves quoting correctly where the legacy regex left an unbalanced quote; documented as an intentional, non-lossy behavior change. (4) smart-entry: added a fallback-only loadWithAmbiguousColonRepair so a column-0 key: value line whose value itself contains an unquoted colon (the #2571 hand-edited-STATE.md shape) round-trips instead of failing the whole frontmatter block closed. (5) frontmatter.unit.test.cjs bracket-array leniency: added a second fallback, repairMalformedInlineArrays, restoring the legacy scanner's tolerant inline-array handling (consecutive/blank commas, unclosed bracket) -- both repairs run ONLY after the primary parse already threw, so well-formed documents are unaffected. (6) prompt-injection-scan: src/frontmatter.cts had a literal U+FEFF BOM embedded in a comment illustrating the #2977 fix; replaced with the U+FEFF text escape. (7) eslint-glob-coverage: allowlisted the new src/vendor/js-yaml.d.cts vendored type declaration, same precedent as the existing re2js.d.cts entry. (8) frontmatter-golden-parity: git ls-files *.md now runs with -c safe.directory=* (process-scoped) so it survives the remote runner's dubious-ownership check without a persistent git config write.

* test(#3881): make golden parity resistant to unrelated tree churn

A corpus-wide snapshot keyed to every tracked *.md file was coupled to mutable-by-design files: .changeset/*.md's pr:0 -> real-PR-number backfill is a required workflow step, not a parser change, yet it turned this suite red. Training people to 'just regenerate the golden' on that kind of failure defeats the point of the snapshot. Exclude .changeset/** from the golden corpus entirely, tolerate tracked *.md files with no golden entry (they postdate the capture) instead of failing on them, keep hard failures for a golden entry whose file has vanished from the tree and for any real parity divergence, and add a coverage floor so the enumeration cannot quietly degrade to comparing a handful of files. Golden regenerated by recompiling the legacy pre-migration parser (git show ddde001af:src/frontmatter.cts) standalone, independent of the current parser, over the same non-changeset corpus.

Refs #3881

* test(#3881): make the parser golden hermetic instead of tree-keyed

This repo merges ~21 commits/day; a 14-day sample measured 937 touches of the
exact files (commands/gsd/*.md, gsd-core/workflows/*.md, agents/*.md,
docs/*.md) the prior golden pinned by tracked path. Any PR editing one of
those files' frontmatter for reasons unrelated to the parser (an
argument-hint addition, an allowed-tools tweak) turned the suite red, and the
reflex fix -- "regenerate the golden" -- overwrote the very snapshot meant to
catch a real regression. Excluding .changeset/** was not enough; the design
itself was wrong: a regression fixture must not be keyed to mutable repo
paths, and a single 376-entry JSON every such PR touches is also a
guaranteed merge-conflict surface.

Rebuilt the fixture to carry its own documents: each of 51 entries stores a
stable id, literal documentText (shrunk from a real ddde001af-era corpus
document), and an expectedParse captured independently from the
pre-migration legacy parser (git show ddde001af:src/frontmatter.cts,
compiled standalone against its byte-identical sibling modules). The test
reads no tracked path, shells out to no git command, and enumerates no tree
-- a PR editing commands/gsd/help.md cannot affect it. Every entry's
reconstruction was verified at capture time to reproduce both the current
and legacy parser's output on the original document; 0 of 51 candidates
were dropped by that check (1, the deliberately-unterminated
unclosed-block.md adversarial fixture, has no closing fence to truncate at
and is stored unshrunk). Kept the 5 documented DIVERGENCES rows (now
diverges:true entries) and the D2 order-preserving structural serializer
that keeps the comparison from passing vacuously; dropped the
tree-enumeration helpers, the coverage floor, the post-capture-skip logic,
and the vanished-file check -- all artifacts of the path-keyed design.

Refs #3881

* fix(#3881): resolve vendored-deps paths independently of cwd shape

Five rows in tests/lint-vendored-deps-manifest.test.cjs failed on
windows-latest CI: the test passed absolute scratch-file paths into
compareFiles()/checkRow(), whose helpers joined every input onto ROOT
via path.join(ROOT, rel), producing garbage when the input was already
absolute. It surfaced on windows-latest specifically because GitHub's
Windows runners checkout the repo on a different drive than TEMP, so
path.relative(REPO_ROOT, tmpFile) returned the absolute path unchanged
(no relative traversal is representable across drives) rather than the
relative form the test assumed. The remote gsd-test runner this repo
gates pushes on is Linux-only and could never have caught this;
GitHub CI's windows-latest job is the only signal that does, and it did.

Fixed the helper itself (scripts/lint-vendored-deps.cjs's new
resolvePath()) to treat an already-absolute input as absolute-in,
absolute-out instead of silently mis-joining it, and updated the test
to pass the scratch file's absolute path directly rather than relying
on a relative conversion that is not always representable. Kept every
mutation-sensor assertion intact and added coverage proving
resolvePath is a no-op for relative inputs and correctly passes
absolute ones through unchanged.

* fix(#3881): warn when state sync regenerates over unparseable frontmatter

state sync (ADR-3408 §8.3's sanctioned regenerate path) correctly
overwrites an unparseable frontmatter block per its 'body wins'
contract — that overwrite behavior is unchanged here. The defect was
the silence: synced:true/exit 0 gave no signal that the existing
block (including git merge-conflict markers) could not be parsed and
was destroyed, per ADR-3473 §8.5 ('a derived conclusion may not be
reported as authoritative when the derivation dropped input it could
not resolve') and §8.4 ('failure is a value').

Adds a gsd: warning — ... (#3881) line on stderr, matching the
existing #3573 precedent, and surfaces the same disclosure in the
JSON result's existing changes[] array so a machine consumer sees it
too. Exit code and synced:true are left unchanged — sync did what its
contract says.

REGENERATE_STATE (/gsd-health --repair's sibling on the same
sanctioned-regenerate list) is DESTRUCTIVE-risk and unconditionally
refused by applyRepairs's dispatcher before runRepairAction ever runs
(src/health-diagnostic.cts), so it is not a live path today and is not
in scope for this fix.

* revert(#3881): restore exit-0 result envelopes for state errors

Reverts 9638f2936 and its changeset. The change was wrong and the revert is
the correction.

This repo distinguishes two error mechanisms deliberately. error() in
src/io.cts writes to stderr and calls process.exit(1) -- the hard-failure
path. output({error: ...}) writes a JSON result envelope to stdout and returns
normally with exit 0. The reverted commit converted 23 result-envelope sites
into hard failures, which is a different contract, not a bug fix.

tests/state-contract.test.cjs's errorPathDoesNotPublish asserts the envelope
contract directly -- a failing command exits 0 with a JSON error envelope and
must not publish state.json -- and the remote matrix run caught it along with
four cases in the QA scenario walk. Thirteen tests in tests/state.test.cjs that
the original commit rewrote were encoding that real contract, not the bug it
claimed; they are restored.

Whether an error envelope on stdout with exit 0 is the right CLI design is a
genuine question, and it is section 8.4's rule ('failure is a value') with its
own phase. It is not something to flip inside this PR.

* test(#3881): keep the frontmatter mutation shard inside its time budget

The Stryker (frontmatter) shard hit the documented 15-minute (900s) shard
cap. Root cause is NOT row-level spawn overhead (contrast the #2790/
core-utils precedent): the three shard test files' own logic runs in
~413ms total (356+30+27ms) with all 392 assertions passing. Instead,
src/frontmatter.cts grew from ~825 to 1496 lines (+671/-187) migrating to
the vendored YAML parser, proportionally growing the mutant count Stryker
generates for gsd-core/bin/lib/frontmatter.cjs. Stryker's command runner
bills the full 'node --test <3 files>' invocation once per mutant, and
node:test's default per-file process isolation forks a child process for
each of the three files on every one of those invocations — pure fork
overhead multiplied by a much larger mutant population.

Fix: scripts/mutation-matrix.cjs COVERED.frontmatter now declares
isolation: 'none', and .github/workflows/mutation.yml passes
--test-isolation=${{ matrix.isolation }} (defaulting to 'process' — i.e.
unchanged behavior — for the other 8 shards, which were not individually
audited for cross-file state leakage under shared-process execution).
Measured locally via node:test's run() API on the exact 3-file set:
isolation:'process' took ~593ms vs isolation:'none' ~478ms for the same
392 passing assertions. The true CI-shard number can only be confirmed
on the GitHub Actions run (Stryker cannot run locally, and 'node --test'
is hard-blocked in this environment).

* test(#3881): register the vendored-parser tests in the frontmatter mutation shard

stryker.config.mjs's own rule ("Keep this list in sync with the tests
arrays in scripts/mutation-matrix.cjs COVERED") was violated: #3881 grew
src/frontmatter.cts from ~825 to 1496 lines but its new tests
(tests/feat-3881-yaml-parser-consequences.test.cjs,
tests/frontmatter-golden-parity.test.cjs,
tests/frontmatter-roundtrip.property.test.cjs, and +167 lines in
tests/frontmatter.test.cjs) were never added to the frontmatter shard's
tests array, so Stryker's mutants in the new vendored-js-yaml adapter had
nothing constraining them. PR #3888 measured 55.8% against the 65 floor
(748 killed / 593 survived / 17 timeout) and the shard was separately
cancelled at 15m04s against the 15-minute per-shard cap.

Registers all four files (each earns its slot on evidence of a unique
constraining assertion, documented inline), gives the shard a
measured/projected 180-minute budget via a new per-module
timeoutMinutes field threaded through mutation.yml's job-level
timeout-minutes the same way isolation is threaded, and removes the
prior isolation:'none' override (re-measured at this file-set size, its
savings are within run-to-run noise, not worth the unaudited
cross-file-state-leakage risk).

* test(#3881): ratchet five stale mutation floors and close the frontmatter gap

Raised five module minScore floors per CI run 33012034388 (floor(achieved)-1):
config-schema 75.51%->74, prompt-budget 88.95%->87, context-composer 79.92%->78,
context-utilization 92.31%->91, active-workstream-store 87.42%->86. Updated both
scripts/mutation-matrix.cjs COVERED entries and tests/mutation-matrix-ratchet.test.cjs
RATCHET_BASELINE in the same diff per the ratchet's own contract.

Closed the frontmatter shard's 63.03%-vs-65 gap with new behavioral tests in
tests/feat-3881-yaml-parser-consequences.test.cjs, each paired with a documented
near-miss: frontmatterDeepEqual's array-order/length/type-mismatch/key-order
semantics (via spliceFrontmatter's no-op guard), scalarNeedsDoubleQuoting's
leading/trailing-whitespace and dash/surrogate triggers (via reconstructFrontmatter),
repairAmbiguousColonValues' already-quoted vs ambiguous-colon repair paths (via
extractFrontmatter), and the null-byte sentinel round-trip surviving at region
offset 1. Did not lower minScore.

* test(#3881): decouple the ratchet test from real module floors

The CLI end-to-end rows in tests/mutation-score-ratchet.test.cjs hardcoded config-schema's real floor (52), which commit 973321541 legitimately ratcheted to 74 -- breaking a test pinned to the exact value the mechanism under test exists to change. Add an injectable --matrix seam to scripts/check-mutation-score-ratchet.cjs and point the CLI rows at a synthetic module + synthetic floor built via a temp fixture, so the rows are indifferent to any real module's floor moving while still exercising the same fail/pass behaviour.

* fix(#3881): restore the ambiguous-colon repair its hand-edited-STATE.md contract needs

A tracked-document sweep of 910 *.md files cannot see this dependent: repairAmbiguousColonValues's one real caller is user hand-edited STATE.md content that never lives in this repo's tree, only on end users' machines, and is pinned by tests/smart-entry.unit.test.cjs. Restores the function plus its post-throw fallback path (loadWithAmbiguousColonRepair) only; repairMalformedInlineArrays and splitLegacyInlineArrayItems stay deleted, reverified against the full frontmatter test shard. Adds a frontmatter-level regression row in tests/feat-3881-yaml-parser-consequences.test.cjs so the dependency is visible where the function lives.
