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.

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.

5d4c98cde7 chore(#4729): guard the retired-runtime name, and finish the locale residue (#4753)
* chore(#4729): guard the retired-runtime name, and finish the locale residue

Phase 5 of 5 on epic #4709, and the phase that closes it. Two parts, one
concern: make the tree clean, and keep it clean. The guard is inert until the
tree is clean, and shipping the cleanup without the guard is the
one-bug-at-a-time pattern this epic exists to end.

WHY A GUARD, AND WHY LAST

Nothing in CI answered "does any shipped surface still present a retired
runtime as live?", and the two gates that look like they should cannot.
checkReviewerDocsParity is one-directional: it asserts the PRESENCE of every
declared reviewer flag and never the ABSENCE of a retired one, so in #4716 it
reported 0 violations while all four locale mirrors still documented --gemini
as a live reviewer flag, with usage examples. And
tests/gemini-runtime-removed.test.cjs is scoped by construction - its own
docblock limits it to the installer CLI contract and the runtime-name-policy
exports; it never reads docs/**, gsd-core/workflows/**, commands/** or
agents/**. Every extension to it during this epic was a hand-added assertion
for a surface somebody had already noticed.

A guard written earlier would have red-flagged the very references phases
1b-4b were removing, which is why it lands last.

PART A - THE RESIDUE, INCLUDING WORK I SHIPPED INCOMPLETE

Each site was judged against its ENGLISH counterpart, not on its own:

  README.{ja-JP,ko-KR,pt-BR,zh-CN}.md :9 :24 :46  English README.md has ZERO
                                                  occurrences -> substituted
                                                  "Antigravity CLI, Kimi CLI"
  how-to/execute-a-phase.md:88  x4 locales        fixed in #4728 -> substitute
  how-to/verify-and-ship.md:89  x4 locales        fixed in #4728 -> substitute
  FEATURES.md cross-AI CLI list                   :1419 no Gemini -> DELETE
  FEATURES.md REQ-MULTI-RT-01                     :1709 -> substitute
  FEATURES.md REQ-SKILLS-03                       :1952 -> rewrite
  FEATURES.md REQ-QUOTA-02                        :3256 deleted upstream -> delete
  VERSIONING.md:133                               stale manifest -> see below

The twelve README occurrences were an adversarial reviewer's BLOCKER, and the
reason they survived my own sweep is structural: root-level *.md was outside
the guard's scan set, so the repo's most-read runtime-advertising surface was
invisible to the guard meant to police it. :46 is a live installer-runtime
claim - it tells the reader the installer will offer a runtime that no longer
exists. Checked for the duplicate-name trap before substituting: neither
Antigravity nor Kimi appears anywhere in those four files.

Two of these are mine to own: I fixed the ENGLISH execute-a-phase.md and
verify-and-ship.md in #4728 and left all four mirrors behind. Unfinished work,
not a deferral.

Two more show why "substitute Gemini -> Antigravity" is the wrong default: in
the cross-AI list and REQ-QUOTA-02 English DELETES the name, because
Antigravity was already in the list or the classifier had dropped it.
Substituting would have duplicated a name - the identical trap
ARCHITECTURE.md:24 set in #4728, where English holds Kimi CLI in that slot.

VERSIONING.md:133 is a different and worse defect than translation lag. Under
"Manifest Version Sync" it listed gemini-extension.json as a version-synced
manifest. That file is ABSENT from the repo, and
scripts/sync-manifest-versions.cjs says so in its own comment - "#1928:
gemini-extension.json was removed with the gemini runtime ... it is no longer
a registered manifest" - while VERSIONED_MANIFESTS holds plugin.json,
marketplace.json and vscode/package.json. So the doc named a manifest that
does not exist AND omitted the one that replaced it. Both fixed, verified
against the owning code rather than inferred from the name. The replacement
bullet cites #1942, the issue that actually registered vscode/package.json,
matching the convention of its neighbours.

pt-BR/FEATURES.md is a 77-line stub genuinely lacking two sites, and ko-KR has
no REQ-QUOTA-02 line. Skipped and recorded, never invented.

PART B - THE GUARD

scripts/lint-retired-runtime-name.cjs, modelled on
scripts/lint-legacy-dir-name.cjs - the repo's own precedent for this problem
shape (forbid a retired token, allowlist frozen content, self-exempt via a
split literal, a REPO_ROOT test seam, lib/cli-exit.cjs, exit 0/1).

Case sensitivity IS the mechanism, not an accident. The naive guard - "the
string gemini must not appear" - is WRONG, not merely noisy: that string is
load-bearing across Antigravity's real on-disk contract. A case-sensitive,
standalone, capitalised name works because every legitimate reference is
spelled differently and therefore cannot match: lowercase config homes
(~/.gemini/antigravity, ~/.gemini/config, #3738), lowercase hyphenated model
ids (gemini-2.5-flash-lite), uppercase env vars (GEMINI_API_KEY), and
GEMINI.md. Table-driven, so the next retired runtime costs one row.

THE ALLOWLIST IS THE ENTIRE RISK SURFACE, so it is three tiers, not one. Two
rounds of isolated adversarial review reshaped it; both are recorded in
.gsd/bug/chore-4729-gemini-drift-guard/60-review.json.

ROUND 2 FOUND ONE ROOT CAUSE BEHIND TWO SEPARATE HOLES, and it was mine: both
Tier-1 rules treated the ABSENCE of a runtime word as a GRANT. A veto list can
never be complete, so "no runtime word found" silently exempted every phrasing
nobody had enumerated. Demonstrated: `The installer now offers Gemini 3.`,
`Supported agents include Gemini 3, Kimi, and Cursor.` and three more exited 0,
as did `Suportamos Gemini, no estilo padrao, como runtime de instalacao.` and
`Gemini 兼容,并且是受支持的运行时之一。`, both of which literally contain `runtime`
or `运行时`. The fix was to stop enumerating exceptions and invert the evidence
direction:

  Tier 1(a) - the hook DIALECT Antigravity inherits. Position is
  language-dependent and MEASURED: en Gemini-style/-compatible, ja Gemini
  スタイル, ko Gemini 스타일/호환, zh Gemini 风格 / 与 Gemini 兼容的, pt "no estilo
  Gemini" / "compatível com Gemini" where the qualifier PRECEDES the name. The
  marker must now form an ADJACENT COMPOUND with the name, not merely sit in a
  +/-24-character window - that window let `| Antigravity | Gemini-style hooks
  | Gemini support is live |` exit 0, one legitimate reference licensing a
  fresh live claim 21 characters later. The runtime-word veto is now
  LINE-GLOBAL. Ten real lines legitimately pair a dialect compound with a
  runtime word (`~/.gemini/antigravity-cli` in a table cell, "runtime files"
  in the same sentence); each is an explicit pin rather than a reason to
  loosen the veto for everyone. Measured: widening it surfaced exactly those
  ten and no others.

  Tier 1(b) - the provider/model axis. A version optionally followed by a
  qualifier, including full-width digits and CJK punctuation, AND positive
  model-axis evidence on the line, AND no runtime word. The positive
  requirement is the part that matters: all eight real model-axis lines in the
  repo name a model explicitly, so requiring it costs nothing on the real tree
  while flagging every laundering attempt. It is also the honest resolution of
  the agent/target tension below - rather than guess at an exhaustive veto
  list, stop treating an empty veto as evidence.

  Tier 2 - PINNED OCCURRENCES, now SPAN-SCOPED. A pin excuses only a match
  falling INSIDE an occurrence of its own snippet. Line-level containment let
  `Known provider menu update: Gemini CLI is once again a selectable GSD
  runtime.` and `Install target: Google (Gemini) - choose Gemini CLI as your
  GSD runtime.` both exit 0, because a short snippet elsewhere on the line
  pre-approved a brand-new claim. Span scoping makes short snippets safe:
  `Google (Gemini)` can only ever excuse the match inside those 15 characters.
  A LOAD-TIME validator now requires every pin to contain a retired name, and
  it immediately caught five of MY OWN pins whose snippets sat BESIDE the name
  rather than covering it - each would have shipped permanently inert and
  permanently reported stale. All pins were then reconciled in one pass.

  A pin is also marked used by PRESENCE on the line now, rather than only on
  the Tier-2 branch. Previously a pinned line that a general rule also matched
  never marked its pin used, producing a provably FALSE "no line matches
  pinned snippet" whose printed remedy told the maintainer to delete a pin
  that was still needed.

  Tier 3 - blanket trust, and a new occurrence inside it IS invisible.
  CHANGELOG.md and `.changeset/` - the rendered changelog and its source, one
  surface - plus six append-only directories. All 21 `.changeset/` hits were
  measured to be fragments DESCRIBING the retirement or a fix to it, 464 of
  them under archived/; a fragment can only describe what already shipped and
  is deleted at release, so pinning them would be friction with no signal. The
  cost is stated in the guard's own header rather than hidden.

THE SCAN SET IS NOW EVERY TRACKED *.md FILE (1165 read). The original prefix
list left `.github/`, `.changeset/`, `capabilities/`, `playbooks/` and
`references/` invisible - and `.changeset/*.md` renders into CHANGELOG.md, so a
live claim introduced there was invisible at BOTH ends.

The escape hatch must now carry a justification
(`gsd-allow-retired-runtime-name: <reason>`). A bare marker is rejected: it is
checked first, excuses the whole line, and the failure message advertises it,
so an unexplained one is indistinguishable from a silenced defect.

Plus an anti-vacuity floor counting files actually READ, not files listed - a
candidate count stays healthy-looking even if every read failed.

A FALSE NEGATIVE I INTRODUCED, AND CLOSED

The model-display escape began as a blanket /^ \d/ - "space then a digit" -
which also matched "Install for Gemini 2.5 CLI as a supported runtime.",
laundering a genuine stale-runtime claim through an attached version number.

That was the THIRD appearance of one failure shape in this epic: an exclusion
added to suppress false positives creating a false negative. #4716's sweep
excluded lines matching gemini-[0-9] to spare Google's model ids, and thereby
hid a stale review.models.gemini row whose example value was "gemini-2.5-pro"
ON THE SAME LINE. Round 2 then produced the FOURTH and FIFTH instances, which
is why the fix this time was to invert the rule's evidence direction rather
than to enumerate more exceptions.

The veto is word-anchored for Latin terms - unanchored, case-insensitive "CLI"
matched inside "client" and would have vetoed legitimate model lists - and raw
for CJK terms, where \b is ASCII-word-based and would never fire beside an
ideograph, so anchoring them would silently disable the veto in ja/ko/zh.
"agent" and "target" were deliberately left OUT: both occur throughout
ordinary prose ("AI coding agents (Claude Code, Codex, Gemini 2.5 Pro)"), so
vetoing on them would red correct content instead of catching runtime claims.
The reasoning is in the guard's comment, not just the omission - and Tier
1(b)'s positive-evidence requirement is what makes that omission safe, since
the rule no longer depends on the veto list being complete.

COVERAGE

tests/lint-retired-runtime-name.test.cjs drives the guard through its
GSD_LINT_RETIRED_RUNTIME_REPO_ROOT seam against fixture repos, mirroring
tests/lint-legacy-dir-name.test.cjs. A guard never observed failing is not a
guard, and this epic already shipped one that was vacuous for 2 of its 5
files, so properties are paired against BOTH failure modes - too broad
silently absorbs a future defect, too narrow reds on legitimate content. Floor
boundaries are covered at 149/150/151.

The round-2 reviewer's sharpest point was about that claim, and it was right:
the first matrix's pairing was "true of the properties chosen, not of the
predicate's actual surface" - not one of its twenty properties could see the
dialect adjacency hole, a non-adjacent runtime word, pin shadowing, or an
over-broad pin colliding with a new line. Every one of those is now a
committed regression using the reviewer's own attack line verbatim, and the
local fixture harness went from 14 cases to 35 (PASS=35 FAIL=0).

That harness earned a finding of its own. Its first run reported PASS=2
FAIL=12 with BOTH passes VACUOUS: `git add` has no -q flag on this build, so
nothing staged, every fixture hit the empty-walk error path, and the two
checks that assert an ABSENCE passed off that error path rather than off real
guard logic. A staging failure is now fatal and every absence-asserting check
first proves the walk ran and the expected violation was flagged. Later, one
case failed because its fixture supplied only one of a pinned file's two
approved lines, so the stale-pin check fired correctly - the expectation was
wrong, not the guard. Telling those two apart is the whole value of running a
matrix rather than reasoning about one.

On the two orthogonal reviews: the isolated adversarial pass executed a great
deal of code, across two rounds, against its own fixture repos. The security
pass did NOT - it self-discloses that it verified by reading only, because
node --test is hard-blocked here. Saying so plainly, because "two orthogonal
reviews" without that caveat overstates what the second one established. It
also raised, and I cleared by measurement, a concern that importing
escapeRegex from a gitignored build artifact would break lint:ci on an unbuilt
clone: six other tracked scripts already require that exact path, three of
them already in lint:ci, and .github/workflows/test.yml:192-193 runs
`npm run build:lib` immediately before it for exactly this reason.

Part A has no new test deliberately - those edits are covered by the guard
itself inside lint:ci, and a separate per-locale assertion would duplicate it
and then drift from it. The one exception is the root README case, which IS
pinned: that residue was invisible to the guard rather than merely unasserted,
so the fix is a scan-set change and needs its own regression test.

No mode-bit read-failure fixture was added on purpose: the benches run as
root, where chmod-based IO injection is vacuous, so such a test would assert
nothing.

The test's fixture helpers write throwaway docs/ paths, which trips
lint-docs-guard-registration's reader-name heuristic. Resolved the way that
lint documents - a header `// docs-guard-exempt:` marker plus a baseline entry
- because the fixtures only WRITE scratch data and never read shipped docs;
the baseline was re-confirmed, not merely extended, each time locale and
adversarial fixtures were added. scripts/lib/macos-conformance-tier.generated.cjs
regenerated through its own --write path, since a new test file changes the
count lint:generated-sync reads.

9b750dc00a fix(#4505): resolve models through the active runtime and the tier table (#4726)
* test(#4505): cover runtime-aware overrides and routing precedence

Failing-first for both halves of the issue, plus the precedence layers a naive
fix silently defeats.

Every row drives the REAL CLI in a subprocess. That is load-bearing: the defect
is WHICH function the shipped call sites reach, so a row calling the resolver
in-process would pass while every real spawn stayed broken. It also makes
GSD_RUNTIME hermetic -- it is ambient, and an in-process row would leak it into
its neighbours.

Two fixture mechanics are documented in the helper because each silently
invalidates a row when got wrong, and both were found by measuring rather than
by reading the loader:

  - the loader reads `process.env.GSD_HOME || os.homedir()`, so redirecting only
    HOME leaves a developer's real ~/.gsd/defaults.json in play;
  - the mere EXISTENCE of a .planning/ directory disables the shared-defaults
    layer, so a fixture that creates one stops exercising the "poisoned global"
    path #2297 acceptance #4 is about. Measured: .planning/ with config ->
    gpt-5.6-terra; .planning/ present but empty -> gpt-5.6-terra; no .planning/
    at all -> "".

Rows cover: both reported repros; the init payload a real spawn reads; the
omit gate, the runtime tier map and model_overrides each outranking the tier
table; model/tier coherence under dynamic routing; resolve-execution with the
attempt absent; max_escalations at limit-1/limit/limit+1 plus a cap of 0; and
four fail-safe rows pinning that only a value canonicalizing to a recognised
non-Claude runtime may outrank an omit.

Registers the docs-guard exemption path: the rows quote the documented
first-spawn contract in comments. The file still never READS a docs/ path.

* fix(#4505): resolve models through the active runtime and the tier table

Consolidates #4495 and #4493. One gap: the function every agent spawn goes
through consulted neither mechanism that was supposed to make resolution
runtime- and tier-aware.

Half A -- the runtime was READ from config, not resolved. resolveActiveRuntime
(GSD_RUNTIME -> config.runtime -> per-install marker -> claude) existed and
worked, but was called exactly once in the file. Every other site read
config['runtime'] raw, and that key is normally absent, so
model_profile_overrides.<runtime>.<tier> was inert for any install that
identifies its runtime through the environment or the marker. Same override
both times, differing only in WHERE the runtime is declared:

  GSD_RUNTIME=opencode, no runtime key   ->  sonnet          (ignored)
  runtime:"opencode" in the config       ->  TEST-OPENCODE   (works)

Half B -- nothing consulted dynamic_routing on the first spawn, though
docs/features/dynamic-routing-with-failure-tier-escalation.md documents
"the resolver picks tier_models[default_tier] for the FIRST spawn".

The tier-table lookup is extracted into ONE helper both entry points call, so
the first-spawn value and the escalated value cannot drift; resolveModelInternal
calls it at attempt 0 and resolveModelForTier at the real attempt.

Placement is the documented composition, not a convenience. The same doc says
"model_overrides always wins; dynamic_routing.tier_models[<tier>] resolves above
models.<phase_type> and model_profile" -- so the step sits BELOW model_overrides,
the model_policy preset, the runtime tier map, the resolve_model_ids:"omit" gate
and the claude tier override, and ABOVE the profile lookup. An earlier cut routed
every call site through resolveModelForTier instead, which returns the tier model
directly and therefore skipped three of those layers: with an omit and a
non-Claude runtime it handed out a model id where the gate had returned "".

Criterion 1 is applied in full, including the two value-policy reads #4192 had
recorded as "NOT via resolveActiveRuntime". The tests decided it: switching them
breaks nothing, so that reading was never enforced -- and the old behaviour
defeated #4192's own principle that an explicit pin must not be silently
unpinned (claude-opus-4-8 under GSD_RUNTIME=opencode collapsed to the Claude-only
alias opus). #4192's comment is updated in place rather than left stale.

The step-3 opt-in signal is CANONICALIZED. Comparing the raw config field against
the literal 'claude' made runtime:"Claude", "claude-code" and even 5 count as
non-Claude opt-ins and outrank an explicit omit -- failing OPEN in exactly the
#2297 case the guard exists to protect. null now covers both "not a string" and
"not a runtime we recognise", and both read as NOT an opt-in.

Verified cell by cell against a pristine origin/next worktree.

4d65c248e5 fix(#4641): make test-conformance the sole Windows selector and narrow the tier to 28.5% (#4643)
* test(#4641): failing-first tests for the tier ceiling and a single Windows selector

Tests only, committed ahead of the implementation so the RED run is real.

- tests/platform-conformance-tier.test.cjs: tier-size ceiling asserted as a
  ratio against a live denominator (Windows 33%, macOS 25%); per-helper negative
  cases proving seam calls and path-call-plus-slash-literal are not platform
  signals; positive pins that genuine platform content, seam-bypassing spawns,
  chmod and symlink still classify in; macOS signal set and generated list
  unchanged.
- tests/ci-full-lane-sharding.test.cjs: the test job has zero windows-latest
  rows and test-conformance still has 3 windows + 1 macOS.
- tests/ci-test-scope.test.cjs: windows_tests is absent rather than empty, a
  non-tier test file no longer forces full_matrix, a RULE-pulled windows-hint
  test does, and resolveSelection rejects the retired windows scope.

* fix(#4641): delete the second Windows selector and narrow the conformance tier

Epic #4589's goal — the OS-agnostic bulk on Linux, a small explicitly-scoped
conformance tier on real Windows/macOS — was not met. Measured on PR #4640
(run 34618834118): 7 non-Linux jobs, a 546/930 (58.7%) "tier", and 5 of 7
changed test files running on a real Windows runner twice.

Two selectors, only one in the epic's scope. The test job's three scope:windows
shards predate the epic (#494, sharded #3057) and gate on product_changed, not
full_matrix, so they fire on every product PR whatever Phase 3's classifier
decides. They are deleted; test-conformance becomes the sole Windows selector,
as it already was for macOS. Non-Linux jobs 7 -> 4.

Gating the lane instead was rejected as provably redundant: for a test file
reachesConformanceTierOrSeam is literally CONFORMANCE_TIER_FILES.includes(file),
and that same predicate sets full_matrix, which turns test-conformance on. Every
file a gated lane would run is already covered in the same run. The lane's one
non-redundant residue -- RULE-pulled tests matched by the isWindowsHint filename
heuristic -- is ported into reachesConformanceTierOrSeam so it sets full_matrix
instead of feeding a parallel lane.

Two detectors matched the repo's own test idiom rather than any platform signal
and carried 226 of the tier's sole-signal membership against 41 for the other
eight: process-seam-subprocess (335 files, 118 unique) matches the
tests/helpers.cjs entry points nearly every CLI test uses, and going through the
seam is the opposite of a platform signal since shell-command-projection takes
platform as an injected parameter; hardcoded-path-vs-path-call (328, 108) needs
only a path call anywhere plus a slash literal anywhere, and that class is
already enforced by ADR-1703's Linux-runnable ESLint rules. Both are removed.
Tier 546 -> 254 (27.3%). src/ reachability is unchanged at 28 files, measured.

Adds the size gate Phase 2 never had, as a ratio against a live denominator so
it cannot stop binding as the suite grows.

292 files leave real-OS Windows execution. The drop-out set was audited: 14 have
a platform-suggestive filename and all 14 are static source-text analyses or
seam-mediated CLI tests. raw-child-process was investigated as a suspected false
negative and left unchanged -- relaxing it adds 13 files, all false positives.

macOS is untouched: MACOS_CATEGORIES is a separate array and the regenerated
macos-conformance-tier.generated.cjs is byte-identical at 196 files.

* fix(#4641): register the new ADR path in the docs-guard exempt baseline

tests/ci-test-scope.test.cjs references docs/adr/4641-windows-selector-consolidation.md
in a comment justifying the retired windows scope; lint-docs-guard-registration
tracks that reference set, so the baseline needs the new path. Verified the
exemption still holds: the path is prose, not a filesystem read.

* fix(#4641): make the escalation tier-backed and drop every hardcoded count

Three follow-ups from measuring the first pass rather than trusting it.

The windows-hint escalation now requires tier membership as well as the
filename hint. Setting full_matrix runs test-conformance, which runs only the
tier; escalating on a test that is NOT in the tier costs four jobs and still
never runs that test on Windows. Measured over the 16 RULES entries the
narrowed predicate fires on exactly the same rules today, so this is
correct-by-construction rather than a behavior change. The broader variant --
escalate on any tier member a rule pulls in, ignoring the hint -- was measured
at 14/16 rules and rejected as over-broad.

Removes the hardcoded counts. A hardcoded macOS tier length of 196 broke as
soon as the rebase pulled in one new test file from #4253, which is the whole
argument against them: the ceilings are ratios against a live denominator, the
committed lists are pinned by comparison against a fresh classification of the
live tree, and the three named probe files now assert on their SIGNAL rather
than on membership in a literal list -- asserting by filename is the exact
error this PR fixes in the classifier.

Regenerates both lists against the rebased tree. Same-tree figures are now
547 -> 255 of 931 eligible (58.8% -> 27.4%), 292 entries removed and none
added; macOS is unchanged at 197 with a zero-line diff.

* fix(#4641): restore real-shell-spawn coverage and repair assertions the narrowing broke

An isolated adversarial review found a real false negative. Removing the
blanket process-seam-subprocess detector also removed the only coverage for
tests that spawn a REAL shell: tests/helpers/process-seam.cjs's runHook
spawns options.interpreter via real spawnSync, so
runHook('-c', [script], { interpreter: 'bash' }) runs a real bash binary
executing a shell script extracted from workflow markdown. The seam argument
holds for src/shell-command-projection.cts, which takes platform as an
injected parameter; it does NOT hold for the test helpers, which spawn real
binaries. Conflating the two is what made the blanket detector look purely
noisy -- it was 99% noise wrapping a real signal.

Adds a narrow shell-interpreter-spawn category keyed on a real interpreter
option. Measured 2026-09-11: 33 files match, 9 were outside the tier and are
added back, taking it 255 -> 264 of 931 (27.4% -> 28.4%), still under the 33%
ceiling. All 9 confirmed by reading the matching source line, zero comment or
fixture matches. runGit-alone and non-node-spawnSeam alternatives were measured
and rejected -- each adds 9 files but misses the counterexample entirely.

Fixes a real bug the suite caught: jobs.test is ubuntu-only now that its
scope:windows rows are gone, so it must wire GSD_STRICT_LIVE_CONFIG_GUARD
strictly rather than carrying the Windows report-only carve-out. The carve-out
now lives solely on test-conformance, whose matrix does include windows.

Repairs seven pre-existing assertions the category removal invalidated,
preserving each case's purpose rather than deleting coverage, and converts the
last hardcoded tier bounds to live-derived ratios -- including the macOS
sanity range that was still a magic [100, 350].

* fix(#4641): keep the confinement test on a real OS via a documented allowlist

A security review found tests/external-descriptor-confinement.test.cjs had
dropped out of the Windows tier. It must stay in, and no content signal can
express why: it exercises isPathConfined (src/external-descriptor-trust.cts),
which uses the AMBIENT path module -- path.resolve(root, target) and path.sep
-- with no injection. Its win32 semantics (drive letters, UNC, separator) are
only reachable by actually running on Windows, and it is a security-relevant
write-confinement gate. A content classifier cannot see 'this module reads the
ambient path module', so no regex belongs here.

Adds ALWAYS_REAL_OS, a Map of path -> recorded reason, unioned into the Windows
tier only. A Map rather than a list so an entry without a reason is impossible
by construction, and tests assert every entry names a file that exists on disk
so a stale entry fails loudly instead of rotting. This is the centrally-
enumerated single source of truth epic #4589 Phase 2 asked for and ADR-1703's
portability-vocab.cjs already models -- deliberately not a heuristic.

Windows tier 264 -> 265 of 931 (28.5%), still under the 33% ceiling. macOS is
untouched and byte-identical: the win32 concern does not apply to a POSIX
runner, and a test asserts the allowlist does not leak into that tier.

* fix(#4641): inject the path impl into isPathConfined and correct the ADR count

Two review findings, both fixed rather than dispositioned.

A security review found tests/external-descriptor-confinement.test.cjs had left
real-OS execution. The allowlist pinned it back, but that only restored
INCIDENTAL coverage: isPathConfined used the ambient path module, and its test
carried POSIX-only literals, so a win32 confinement escape was unverified on
every platform including Windows. isPathConfined now takes an optional third
parameter carrying the path implementation, defaulting to the ambient module.
Blast radius is CRITICAL -- 53 affected symbols across 19 files -- so the change
is purely additive and every existing two-argument caller is byte-identical.

Tests now inject path.win32 and path.posix, covering a different drive letter,
a cross-drive absolute, backslash and forward-slash traversal, UNC, and the
startsWith prefix-boundary bug (.gsdEVIL against root .gsd) on both separators.
Proved load-bearing: dropping the + p.sep from the prefix check fails exactly
the two boundary cases and nothing else. Callers' suites 149/149.

The spec review caught an off-by-one: the ADR narrated a 264-file tier while the
committed list holds 265. The ADR now records the full chain 547 -> 255 -> 264
-> 265 (28.5%).

Also corrects a stale comment in scripts/docs-guard-registry.cjs that narrated
classify() as zeroing windows_tests, a key this change removes -- kept as
historical narration but labelled as such.

* fix(#131): make the unwritable-HOME test actually test something

Found by sweeping for the root-bypass class after fixing commit-files-deletion.
This one is the silent variant, and it was broken twice over.

First, the condition: the test made a fake HOME unwritable with chmod 0o500.
The gsd-test Docker bench runs as root, root bypasses mode bits, so HOME stayed
writable and the hostile condition never existed. Replaced with a HOME whose
PARENT is a regular file, so every write under it fails ENOTDIR at the VFS
layer for every uid -- no permission check is involved at all.

Second, and more fundamental: the probe was npm --version, which on npm 11.19.0
performs zero filesystem I/O against HOME. Proven rather than assumed --
neutralizing runNpm()'s isolation turned the sibling test red while this one
stayed green, so its assertion could never detect the regression it guards, on
any uid, with or without the condition fix. npm config get cache was tried next
and proved vacuous the same way (it only string-resolves the path). The probe is
now npm cache verify, which really does mkdir _cacache under HOME.

Re-proved load-bearing after the change: with isolation neutralized the test now
fails with ENOTDIR on <blocker>/home/.npm/_cacache. tests/helpers.cjs was
restored and verified diff-clean; suite 13/13.

* docs(#4641): correct the net drop-out figure in ADR-4641

The Consequences section still said 292 files leave real-OS Windows execution.
That was the count before the narrow shell-interpreter-spawn replacement
restored 9 and ALWAYS_REAL_OS pinned 1. Net is 282. Also names both real-binary
categories rather than only raw-child-process, and clarifies that the 14-file
filename audit was against the 292 initially dropped.

* docs(#4641): record the rejected concentration ceiling and its measurement

Applying Goodhart's own question to the new ceiling -- how would you make this
metric look good without improving what it represents -- surfaces a real
weakness: a ratio can be satisfied by inflating the denominator, so adding
OS-agnostic tests loosens it without narrowing the tier.

The obvious companion gate was a sole-signal concentration ceiling, since the
original defect was one detector carrying half the tier. Measured and rejected:
peak concentration post-fix is raw-child-process at 53/265 = 20.0%, against the
historic offenders at 21.6% and 19.8%. Any threshold above 20% misses the
original defect; any threshold below it fails on a legitimate category. The
discriminator is whether a signal is platform-meaningful, which no threshold
encodes. Weakness disclosed rather than covered by a gate that does not bind.

* chore(#4641): add the changeset fragment for the confinement-check change

changeset-lint failed on PR #4643: the PR touches user-facing paths and carried
no fragment. The earlier no-changeset call matched #4604's CI-only precedent and
was correct then; it was not revisited once the PR grew a src/ change, which is
my miss.

The fragment describes the real user-visible improvement: the external-descriptor
write-confinement check's Windows semantics are now verified deterministically
rather than only when the suite happened to run on Windows.

* docs(#4641): correct the tier count in TESTING-SUITES.md

Said the tier narrowed from 546 to 254. The final committed list is 265 of 931
eligible (58.8% -> 28.5%) after the shell-interpreter-spawn replacement restored
9 files and ALWAYS_REAL_OS pinned 1. Same error class the spec review caught in
the ADR, in a live reference page rather than a dated record, so it states the
current truth rather than carrying an amendment note.

* docs(#4641): record the measured aggregate from real CI job lists

Epic #4589's closeout asserted its reduction from a static count; #4641's
acceptance criterion asks for a figure read off a real run. Recorded here:
test.yml job count 21 -> 15 and non-Linux 7 -> 4, comparing PR #4640's run
against this PR's own. Against the true pre-epic baseline of 9, that is 9 -> 4.

Also states the caveat that a PR's total CHECK count is not a clean before/after
comparison, since many gates are path-scoped and this change touches a broader
path set -- the like-for-like figure is the test.yml job count.

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

* docs(#4641): compare job totals the same way on both sides

The measured-aggregate table put #4640's COMPLETED run total (21) against this
run's count at matrix-expansion time (15). Those are not the same measurement:
the completed total includes the post-test Coverage gate and baseline-publisher
jobs. Counted identically, it is 21 -> 17. The load-bearing figure, non-Linux
jobs 7 -> 4, was correct and is unchanged.

Called out in the table rather than silently corrected -- comparing two
differently-derived numbers is exactly the error class this ADR is about.

* docs(#4641): record measured conformance wall-clock and date the stale counterfactual

Adds the per-job durations from both runs. The honest read is that this is a
correctness win more than a speed one: file count fell 52% but wall-clock only
9-29%, because what was removed were the cheap static tests and what remains is
concentrated in expensive spawn-heavy work. Stated explicitly so nobody expects
a future narrowing to buy time proportional to file count.

The load-bearing figure is windows shard 3/3: 40m24s against a 45-minute cap on
the 547-file tier -- 90% of the cliff #869 and #3057 were both filed about --
pulled back to 31m27s. macOS moved the wrong way (17m48s -> 21m02s) while its
tier was UNCHANGED at 197 files, which fixes that as runner variance and is
noted as a caution against reading a single duration as signal.

Also dates the symlink-keyword counterfactual, which cited a 254-file tier from
before the replacement category and allowlist took it to its final 265.

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

* docs(#4641): re-measure against the rebased tree and disclose the allowlist's zero

next gained #4644 mid-flight, so every absolute count shifted. Re-measured on
the tree this actually ships against (932 eligible): 548 -> 257 by detector
removal, 257 -> 266 once shell-interpreter-spawn restores 9. Net 282 removed,
9 restored. macOS 198, unchanged by this PR.

The percentages did not move across three rebases (58.8% -> 28.5%), which is
the whole argument for expressing the ceilings as ratios rather than counts --
noted in the ADR since it is now evidence rather than assertion.

Also discloses that ALWAYS_REAL_OS now contributes ZERO files: this PR's own
win32 test cases introduced the literal win32 into the pinned file, so it
classifies in on content via win32-darwin-literal. The entry stays and the
reason is written down, because the file's real-OS need is a property of the
code under test (isPathConfined reads the ambient path module), not of the
test's text -- the text that currently saves it is incidental and could be
refactored away silently.

18c899def5 enhance(#4209): optional external source reviewer lanes for /gsd:code-review (#4323)
* test(01-01): define reviewer-support trait contract

Add failing coverage for step.supportsReviewerLanes (#4209 DISP-02):
validator rejects non-boolean values with an exact field path, accepts
missing/true/false, and the real code-review capability.json steps
must declare supportsReviewerLanes: true. Add loop-resolver projection
coverage proving the trait reaches activeHooks verbatim for a
provider-neutral synthetic step (not code-review-specific), and that
omitted/false values stay inert (no key on the active hook).

All 8 new assertions fail today: the validator has no such field, and
loop-resolver has nothing to project. RED before GREEN.

* feat(01-01): declare reviewer-capable steps

Add step.supportsReviewerLanes (#4209 DISP-02): a strict optional
boolean opt-in trait, step-scoped (not capability-wide). Only a
literal true validates and projects; false/omitted stay inert (no
key on the projected active hook), and every non-boolean type fails
capability-validator.cjs with an exact field-path error.

Opt both existing code-review steps (execute:post, execute:wave:post)
into the trait in capabilities/code-review/capability.json. Project
the validated field through src/loop-resolver.cts into activeHooks
so a provider-neutral generic interpreter can read it without any
code-review-specific knowledge. Document the field in
docs/reference/capability-manifest.md and regenerate
gsd-core/bin/lib/capability-registry.cjs via the generator (never
hand-edited).

Makes all 8 RED assertions from the prior commit pass.

* test(01-02): define shared reviewer dispatch

- Add tests/reviewer-step-dispatch.test.cjs covering dispatchReviewerLanes:
  inert when the supportsReviewerLanes trait is off or nothing is selected,
  exactly-once plan/invoke per selected lane, duplicate-alias dedup, the
  bounded metadata-only source-review prompt (repo root, paths+baseSha,
  depth, four fixed prohibitions), and capability-neutral reuse via a
  second synthetic step context.
- RED: module under test (src/reviewer-step-dispatch.cts) does not exist
  yet, so require() fails and every assertion is unreached.

* feat(01-02): dispatch reviewers for opted-in steps

- Add src/reviewer-step-dispatch.cts: dispatchReviewerLanes(input, deps),
  ONE interpreter for a step's supportsReviewerLanes trait. Reuses
  resolveReviewerSelection for selection and resolveLanePlan for planning
  (both already-existing, pure building blocks); invocation is the one
  required, caller-injected seam (deps.invoke) since runLane needs
  OS-aware spawn plumbing this module does not own.
- trait !== true, or a selection resolving to zero lanes, dispatches
  nothing (zero plan/invoke calls). Each selected lane is planned and
  invoked exactly once, in the selector's deduped/sorted order.
- buildSourceReviewPrompt assembles a metadata-only bounded prompt
  (repo root, canonical paths + base SHA, depth, four fixed
  prohibitions) — never file contents — written once per dispatch and
  shared across every invoked lane.
- GREEN: tests/reviewer-step-dispatch.test.cjs now passes.

* test(01-02): define reviewer dispatch failures

- Extend tests/reviewer-step-dispatch.test.cjs with the fail-closed
  matrix: an explicitly requested lane the selector could not resolve
  still lets the OTHER resolved lane run, but the aggregate result must
  never read as a clean success (and 'every explicit lane unavailable'
  must be distinguishable from the plain no-flags-passed inert case);
  request-level validation (path traversal, absolute paths outside
  repoRoot, empty/non-string paths, missing depth/base SHA) halts the
  whole dispatch before any lane is planned or invoked; a per-lane
  prompt-budget overflow hard-fails only that lane before invoke while
  its sibling still runs.
- RED: src/reviewer-step-dispatch.cts does not yet implement any of
  these guards, so 9 of the new assertions fail against the current
  (Task 1) implementation.

* fix(01-02): fail closed in reviewer dispatch

- src/reviewer-step-dispatch.cts: add the fail-closed guards the prior
  commit deliberately left out. An explicitly requested lane the
  selector could not resolve no longer lets the aggregate read as a
  clean success — lanes that DID resolve still run and keep their
  results (never narrow the requested set), but selection.errors now
  flips the aggregate ok to false, and 'every explicit lane
  unavailable' is now distinguishable (SELECTION_FAILED) from the
  plain no-flags-passed inert case (NO_LANES_SELECTED).
- Add request-level validation (validatePaths, depth/baseSha presence)
  that halts the WHOLE dispatch before any lane is planned or invoked:
  path traversal, absolute paths outside repoRoot, empty/non-string
  paths, and missing provenance are all rejected up front.
- Add per-lane prompt-budget enforcement (resolveBudget, mirroring
  gsd-tools.cjs's budgetFor convention including budget 0 = unbounded):
  a lane whose resolved budget the prompt exceeds hard-fails before
  invoke runs for it, without cancelling a sibling lane already
  planned.
- Document the supportsReviewerLanes trait and its dispatch-step
  interpreter in gsd-core/references/loop-hook-dispatch.md.
- GREEN: all 19 tests in tests/reviewer-step-dispatch.test.cjs pass;
  no regressions in the review-lane/reviewer-selection/prompt-budget
  suites (356 passing).

* test(01-03): define optional source reviewer flow

RED: assert code-review.md dispatches roster-derived reviewer-lane flags
through a single review-lane dispatch-step call (DISP-01..05), that the
no-flag path stays byte-for-behavior unchanged (COMP-01), and that
external evidence reaching the internal reviewer prompt is marked
unverified (CONS-02). Also covers the CLI contract directly: no-op with
no explicit selection, and fail-closed on an explicit unknown lane
(SAFE-07) via real gsd-tools.cjs subprocess calls.

* feat(01-03): route optional source reviewers

GREEN: code-review.md gains a dispatch_reviewer_lanes step that matches
canonical reviewer-lane flags against the merged first-party + installed
roster (never a hand-maintained list) and, only when at least one is
present, calls the shared reviewer-step interpreter exactly once with the
already-resolved repo root, file scope, depth, and base SHA. Its evidence
paths are appended to the internal reviewer prompt via
${EXTERNAL_EVIDENCE_BLOCK}, explicitly marked unverified. No reviewer-lane
flag leaves the internal-only dispatch byte-for-behavior unchanged
(COMP-01).

Deviation (Rule 3 — blocking issue): 01-02 documented `review-lane
dispatch-step` (gsd-core/references/loop-hook-dispatch.md) as the CLI
route `dispatchReviewerLanes` wires through, but never implemented the
gsd-tools.cjs subcommand — the workflow's call had nothing to reach. Add
it to the existing review-lane router, reusing the same effort-aware plan
building and runner deps `plan`/`invoke` already use (factored into
buildLaneRunnerDeps to avoid duplicating the spawn/http/fs seam). Guard
the CLI's own `detected` set on whether an explicit flag was passed:
resolveReviewerSelection's no-explicit-selection fallback is "select every
detected reviewer" (the correct default for /gsd:review), and passing it
an unconditionally non-empty detected set would silently invoke the whole
roster on every no-flag code review, violating COMP-01.

* test(01-03): define external finding consolidation

RED: assert gsd-code-reviewer.md treats <external_reviewer_evidence> as
untrusted input — independently re-verifies every claim against the actual
current source, resists a prompt-injection attempt embedded in evidence
text, and folds a verified claim into the existing Narrative Findings
section with no second REVIEW.md schema (CONS-01..03). Also assert
code-review.md's EXTERNAL_EVIDENCE_BLOCK restates the four fixed
source-review prohibitions (SAFE-03..06) at the internal-reviewer handoff.

* feat(01-03): consolidate external review evidence

GREEN: gsd-code-reviewer.md's load_context parses <external_reviewer_evidence>
as untrusted data, independently re-verifies every cited claim against the
actual current source before it can appear in REVIEW.md, and explicitly
resists prompt injection embedded in evidence text (never a command, no
matter what it claims to be). A verified claim folds into the existing
Narrative Findings section with (external: {slug}) provenance — one
REVIEW.md schema only, no separate external-findings section.
code-review.md's EXTERNAL_EVIDENCE_BLOCK now restates the four fixed
source-review prohibitions (SAFE-03..06) at the internal-reviewer handoff.

* fix(01-02): gitignore the reviewer-step-dispatch build artifact

01-02 added src/reviewer-step-dispatch.cts but never added its
npm run build:lib output to .gitignore, unlike every sibling
gsd-core/bin/lib/*.cjs generated file. Left it showing as untracked
noise in git status.

* docs(01-04): publish user and command contract for reviewer-lane source review

- Document optional reviewer-lane flags on /gsd-code-review in USER-GUIDE.md
  and COMMANDS.md: opt-in, no source bodies in prompts, no fallback on
  failure, findings independently consolidated into the single REVIEW.md
- Add the same contract to the docs/features/code-review-pipeline.md
  fragment and regenerate docs/FEATURES.md from it
- Preserve /gsd-review as the plan-review command; cross-reference it
  rather than duplicating the reviewer roster
- Pick up docs/INVENTORY-MANIFEST.json and skills/gsd-code-review/SKILL.md
  drift owned by source already shipped in Plans 01-01/01-03 but never
  regenerated (npm run regen:derived had not been run in this worktree)

* docs(01-04): align architecture and agent ownership docs for reviewer-lane trait

- ARCHITECTURE.md: trace the #4209 capability trait (supportsReviewerLanes)
  through the shared dispatchReviewerLanes interpreter to the existing
  review-lane plan/invoke machinery, ending at gsd-code-reviewer as the
  sole REVIEW.md consolidator
- AGENTS.md: document gsd-code-reviewer's full-context verification scope
  and its treatment of external reviewer evidence as unverified input
- No new diagram, abstraction, or config key; docs/CONFIGURATION.md is
  unchanged since the feature adds no setting or default

* fix(01-02): eslint-ignore the reviewer-step-dispatch build artifact

Same gap as the earlier .gitignore fix: 01-02 added
src/reviewer-step-dispatch.cts but never added its generated
gsd-core/bin/lib/reviewer-step-dispatch.cjs output to
eslint.config.mjs's ignore list like every sibling generated file,
so tsc's emitted __importDefault CommonJS-interop var tripped
no-var.

* fix(01-04): add the reviewer-step-dispatch.cjs roster row to docs/INVENTORY.md

01-04 regenerated docs/INVENTORY-MANIFEST.json (which now lists
cli_modules/reviewer-step-dispatch.cjs) but the hand-written roster
row in docs/INVENTORY.md — required by design, since a role sentence
cannot be generated — was never added.

* fix(01-01): update the code-review capability-step fixture for supportsReviewerLanes

refactor-trigger-cli.test.cjs's preservesCodeReviewHookShapeAlongsideRefactorHook
strict-deep-equals the code-review step's exact shape at execute:post; 01-01 added
supportsReviewerLanes: true to that step and this fixture was not updated.

* chore(01-03): acknowledge emitted-doc growth for code-review.md and gsd-code-reviewer.md

Both files grew as a direct, intended consequence of wiring optional
reviewer lanes into /gsd:code-review (the new dispatch_reviewer_lanes
step and the untrusted-evidence consolidation contract) — not
incidental drift.

Emitted-Drift-Ack-Growth: code-review.md — new dispatch_reviewer_lanes step and EXTERNAL_EVIDENCE_BLOCK wiring for optional reviewer lanes (#4209)
Emitted-Drift-Ack-Growth: gsd-code-reviewer.md — untrusted external-evidence consolidation contract for optional reviewer lanes (#4209)

* test(01-05): define WR-01/WR-02 reliability contract for dispatchReviewerLanes

From internal code review: dispatched must be false when zero lanes
actually reached plan(), and a throwing plan()/invoke() for one lane
must not discard results already collected for a sibling lane —
matching the fail-closed pattern gsd-tools.cjs already uses for the
same resolveLanePlan call (#2494/#2605/#1698/#1936/#2073/#2176/#2589/#2794).

Refs: gsd-core-dks.16, gsd-core-dks.17

* fix(01-05): close WR-01/WR-02/IN-01/IN-02 from internal review

- WR-01: dispatched now tracks whether any lane actually reached
  plan(), not results.length — an unresolvable selected slug no
  longer reports dispatched:true.
- WR-02: plan()/writePromptFile()/invoke() wrapped per-lane so a
  throw for one lane can never discard results already collected
  for a sibling lane, matching the same guard gsd-tools.cjs already
  has around the identical resolveLanePlan call.
- IN-01: documents the intentional budget===0-is-unbounded
  convention (#2797) the caller already relies on.
- IN-02: review-lane dispatch-step no longer blocks indefinitely on
  an un-piped interactive TTY; fails closed to empty paths instead.

Refs: gsd-core-dks.16, gsd-core-dks.17

* docs(01-05): add changeset fragment for PR #17

* fix(01-03): allowlist prompt-injection-scan false positive on the untrusted-evidence contract

agents/gsd-code-reviewer.md's untrusted-evidence section and its
pinning regression test both quote injection phrases as the exact
attack they defend against/detect — same
DEFECT.PROMPT-INJECTION-SCAN-COLLISION class as the existing
allowlist entries, not an actual injection vector.

* test(01-05): extend WR-02 coverage to writePromptFile/invoke throws; DIFF_BASE-empty skip

From CodeRabbit review: WR-02's earlier fix only wrapped plan() —
writePromptFile()/deps.invoke() still ran unguarded, so a throw
there still aborted every later selected lane. Also covers the
dispatch_reviewer_lanes DIFF_BASE-empty-provenance gap (explicit
lanes silently not running when no prior review and no phase-start
commit exist).

* fix(01-05): skip dispatch_reviewer_lanes with a clear warning when DIFF_BASE cannot be resolved

Previously an explicit reviewer-lane request with no prior review and
no resolvable phase-start commit reached dispatch-step with an empty
--base-sha, which fails closed via missing_provenance — correct, but
silent about why explicitly requested lanes didn't run. Now skip
dispatch entirely in that case with a stderr warning naming the
actual cause.

* fix(01-05): wrap writePromptFile/invoke in the same per-lane try/catch as plan()

WR-02's original fix only guarded plan() — a throw from
writePromptFile() or deps.invoke() still aborted the whole dispatch,
discarding results already collected for lanes processed earlier in
the loop. CodeRabbit caught the gap; WR-02b/WR-02c pin it.

* fix(01-05): WR-02b mock must throw only on the first writePromptFile() call

The committed mock threw unconditionally, so codex's retry also threw and
failed for the same reason as claude's — the test could not distinguish
'sibling still runs' from 'sibling also breaks'. Gate the throw to the
first call, matching WR-02/WR-02c's single-failure intent.

* fix(#4209): close review findings from adversarial + critical-code-reviewer pass

Two independent reviews (agy adversarial review, Opus critical-code-reviewer +
ponytail) found 6 Blocking and 7 Required issues in the reviewer-lane dispatch
wiring around dispatchReviewerLanes. All 13 tracked in gsd-core-dks.18-30 and
fixed here:

- dispatch-step's reducer silently swallowed whole-dispatch rejections
  (invalid paths, missing provenance, etc); it now checks parsed.ok/reason.
- spawn_reviewer recomputed its own stale DIFF_BASE, diverging from the
  LAST_REVIEW_COMMIT-aware value dispatch_reviewer_lanes uses on re-review;
  now shares the single compute_file_scope derivation.
- the external reviewer prompt had no actual review request or citation
  requirement, only prohibitions; added both.
- removed the supportsReviewerLanes trait plumbing (capability registry,
  validator, loop-resolver, docs, tests) — it was never consulted by the
  real dispatch path, which gates on explicit CLI flags instead.
- flag-resolution require() was a fragile cwd-relative literal that failed
  silently on non-vendored installs; now resolves via GSD_TOOLS's own
  directory and warns instead of swallowing failure.
- reducer didn't unwrap the @file: overflow protocol for large payloads.
- deduplicated resolveBudget/budgetFor into one resolveLaneBudget.
- lane artifacts now write to a mktemp run dir instead of $PHASE_DIR, so a
  second dispatch can't overwrite prior evidence.
- validatePaths rejects control characters, closing a markdown-injection
  vector into the external prompt via crafted filenames.
- reworded the one line that tripped prompt-injection-scan.sh instead of
  allowlisting the whole production prompt file.
- fixed a stale docstring range and a dispatched-field ordering bug.
- added 3 integration tests executing the actual reducer against synthetic
  dispatch-step JSON, replacing markdown-substring-only assertions.

771/771 tests pass across every touched suite; tsc --noEmit clean.

* fix(#4209): wire supportsReviewerLanes as the maintainer's required reusable trait

The maintainer's approval on issue #4209 explicitly redirected implementation
shape: reviewer-lane dispatch must be a reusable capability/step-dispatch
trait ("supportsReviewerLanes"), not code-review.md hand-wiring the call
itself. My previous commit (e2558326) deleted that trait entirely after
finding it declared-but-never-consulted, which was backwards — the fix was to
wire it, not remove it.

Restores the trait (capability.json, generated registry, validator,
loop-resolver.cts, docs, tests) and wires it for real: dispatch_reviewer_lanes
now resolves its own active hook via `gsd_run loop render-hooks` for the
configured workflow.code_review_point and only proceeds to CLI-flag matching
when supportsReviewerLanes reads true. Explicit flags no longer bypass the
trait; a matching flag with the trait false resolves zero slugs (proven by a
new integration test executing the real fence with both trait states).

Emitted-Drift-Ack-Growth: gsd-core/workflows/code-review.md — the
dispatch_reviewer_lanes step grows a trait-resolution fence (#4209 maintainer
redirect requires the capability layer, not the workflow, own the opt-in
decision).

* fix(#4209): dispatch-step self-verifies the reviewer-lane trait via --cap-id/--point

Both an agy adversarial review and an Opus critical-code-reviewer pass
independently found the same gap in my previous commit (9b2c3773d): the trait
check I wired into code-review.md only protected code-review's OWN
invocation — gsd-tools.cjs's dispatch-step handler still hardcoded
`trait: true` unconditionally, so a second capability declaring
supportsReviewerLanes would get zero enforcement from the shared CLI unless
it correctly re-implemented the ~15-line render-hooks scrape itself. That is
exactly the "each workflow.md hand-wiring the call" the maintainer's redirect
said to eliminate.

Moves the trait check into dispatch-step itself: given --cap-id/--point, it
self-invokes `loop render-hooks <point>` (relocating the one subprocess
code-review.md used to spawn for this, not adding a new one) and derives the
real trait from that capId's active hook, rather than trusting a
caller-passed boolean. code-review.md now only passes
--cap-id code-review --point "$CODE_REVIEW_POINT" and no longer resolves or
gates on the trait itself — the ~20-line scrape it previously carried is
gone. Any other capability opts into the identical enforcement by declaring
the trait and passing the same two flags.

Replaced the two tests that stipulated SUPPORTS_REVIEWER_LANES as an input
variable (they proved a bash branch honors a variable, not that the variable
reflects the real capability manifest) with three integration tests that
invoke the real dispatch-step CLI against the real first-party capability
registry: the real code-review trait resolves true, an unknown --cap-id
resolves false (trait_not_enabled, fail-closed), and omitting
--cap-id/--point entirely resolves false (no context means no opt-in).

Also: reject \x7f/U+2028/U+2029 in validatePaths' control-character check
(agy-F1 was incomplete), and delete the promptWritten per-lane coupling
flag — the prompt write is idempotent, so writing it once per lane instead
of gating on "did any lane write it yet" removes a latent bug where a
deps.plan override that ever varies promptPath per lane would silently skip
writing for a later lane.

Emitted-Drift-Ack-Growth: gsd-core/workflows/code-review.md — net line count
drops (the trait scrape moved into dispatch-step), but the file still grew
this session across multiple commits; acknowledging per the growth-tracking
convention.

* fix(#4209): remove per-run token waste from the shipped prompts

Runtime prompt content, not session tokens: two real, per-invocation token
costs in the code that ships.

1. agents/gsd-code-reviewer.md's critical_rules restated nearly all of
   load_context step 5's ~180-word untrusted-evidence contract in ~90 more
   words, breaking this section's own established terse one-liner style
   (every other rule here is 1-2 sentences). This prompt loads fresh on
   every /gsd:code-review invocation. Shrunk to a one-line cross-reference,
   matching how write_review's own reference to step 5 already does it.

2. buildSourceReviewPrompt repeated the base SHA on every single file line
   even though it is identical for every file and already stated once at
   the top of the prompt — O(files) wasted tokens on every dispatched lane
   for a 50-file review, for zero information gain. File lines are now bare
   paths.

* fix(#4209): resolve reviewer-lane trait in-process, fix CI failures found in review round 3

Opus critical-code-reviewer found a real Blocking defect in the --cap-id/
--point self-invocation added last commit: `dispatch-step` spawned
`loop render-hooks <point> --raw` as a subprocess and bare-JSON.parse'd its
stdout, but `io.cjs`'s output() redirects any payload over 50000 chars to
`@file:<path>` instead of inline JSON -- the same overflow protocol this
feature already unwraps for its OWN dispatch result 60 lines later in
code-review.md. A large-enough activeHooks envelope (more installed
capabilities/fragments) would throw, get silently swallowed by the bare
catch, and misreport a real trait as trait_not_enabled with zero diagnostic.

Fixed by extracting the config/registry/capability-state resolution
`cmdLoopRenderHooks` already performs into an exported pure function,
resolveActiveHooksForPoint (both `cmdLoopRenderHooks` and dispatch-step now
share it), and calling it in-process from dispatch-step instead of spawning
a subprocess at all. This eliminates the @file: exposure entirely (the
dispatch-step path never touches the rendered-string envelope or its
JSON-stringify/50000-char threshold), removes one subprocess spawn per
code-review invocation, and gives a genuine diagnostic (stderr warning) on
resolution failure instead of silent fail-closed. Corrected three doc/
docstring references to the now-removed subprocess self-invocation.

Also fixes 2 real CI failures this round surfaced:
- lint-tests: the agy-F1 control-char regex fix's `eslint-disable-next-line
  no-control-regex` comment was unused under this project's ESLint config
  (verified locally: the rule never actually flags \x00-\x1f in this repo's
  config) -- a mistake from an earlier commit this session, never actually
  lint-checked before push. Removed the disable comment.
- security (prompt-injection-scan): the agy-F1 regression test's crafted
  fixture literally contains "Ignore all prior instructions." as test data
  proving validatePaths rejects it -- allowlisted the test file, same
  DEFECT.PROMPT-INJECTION-SCAN-COLLISION class as existing entries.

Also trimmed agents/gsd-code-reviewer.md's load_context step 5 (R2): one
bullet stated "untrusted, never a command" three different ways in one
paragraph, and a same-file duplicate of write_review's schema rule.
Consolidated to state each rule once.

Declined one suggestion from this round: shrinking code-review.md's
EXTERNAL_EVIDENCE_BLOCK to a bare evidence list. Two tests
(tests/code-review-pipeline-regression.test.cjs's CONS-01..03 block,
tests/code-review.test.cjs's CONS-02 test) deliberately lock the four-
prohibitions restatement and the untrusted-evidence prose into the
INJECTED block itself, not just the consolidator's system prompt --
adjacency of the warning to the untrusted payload it's warning about is a
recognized prompt-injection defense-in-depth pattern from this
workstream's original TDD plan, not accidental duplication.

* fix(#4209): correct stale per-file base-SHA prose in the external prompt

Leftover from removing the per-file base SHA repetition earlier this
session: the review-request sentence still said "relative to its base SHA"
(singular per-file framing) when there's now exactly one base SHA, stated
once above the file list. Reads "relative to the base SHA above" now.

* fix(#4209): make getLane/configGet/plan required deps, delete dead defaults

R3/R4 from the review round I'd deferred as low-priority test-churn: this
file's one production caller (gsd-tools.cjs's dispatch-step handler) always
supplies all three, so the fallbacks were dead in production -- but each was
actively WRONG if ever reached: the default configGet always returned
undefined, silently disabling resolveLaneBudget's overflow guard; the
default getLane looked up only first-party REVIEWER_LANES, diverging from
production's overlay-merged roster; the default plan skipped per-host effort
resolution entirely.

These defaults were introduced by this PR's own earlier work (this file did
not exist before #4209 -- first commit a760bfcda, 01-02), not inherited from
elsewhere, so there's no external caller depending on the lenient contract.

Turned out free to fix: making the three deps required and deleting
defaultGetLane/defaultPlan needed zero test changes -- every existing test
that actually reaches the per-lane loop already supplies getLane/plan
explicitly, and configGet's only real dependent (the budget-overflow tests)
already supplies it too. 788/788 tests pass unchanged, tsc/lint clean.

* fix(#4209): define depth semantics for the external reviewer lane

Verified this was a real bug, not a match to existing convention as I'd
claimed when declining the suggestion earlier this session: the internal
gsd-code-reviewer agent's own system prompt carries a full <depth_levels>
block defining what quick/standard/deep mean and do (agents/gsd-code-
reviewer.md:68-99). The external reviewer lane has no access to that
persona at all -- it only ever sees buildSourceReviewPrompt's bounded text,
which sent the bare depth label with zero definition to a third-party CLI
with no other source of truth for what "standard" means.

Added depthMeaning(), condensed from the internal reviewer's own
<depth_levels> definitions so the two stay consistent, and interpolated it
into the review-request sentence. 150/150 tests pass, tsc/lint clean.

* fix(#4209): merge dispatch_reviewer_lanes' split fences into one shell invocation

CR-01 (Opus critical-code-reviewer, confirmed by direct execution): the
roster-matching fence set EXPLICIT_JOINED/EXPLICIT_REVIEWER_SLUGS, and a
SEPARATE later fence read them via ${#EXPLICIT_REVIEWER_SLUGS[@]} to decide
whether to dispatch at all. This file's own documented rule (its
depth-resolution guard, stated explicitly a few hundred lines earlier) is
that a guard and the extraction it protects must run as one shell
control-flow decision, because markdown-fenced blocks do not share shell
state -- this step violated its own file's rule for the entire feature's
gating condition.

Merged the roster-resolution fence and the dispatch-decision fence into one
continuous bash block, removing the intervening prose that split them.
Fixed the stderr-based failure detection in the same edit (RQ-01: checking
whether stderr is non-empty misfires on any benign Node warning; now checks
the actual exit status of the roster-resolution command).

Verified by extracting the merged fence and executing it standalone, driving
both branches: --codex resolves EXPLICIT_JOINED=codex, SLUGS_COUNT=1, and a
real dispatch-step call succeeds; no flags resolves EXPLICIT_JOINED empty,
SLUGS_COUNT=0, dispatch-step never invoked (COMP-01). 141/141 workflow tests
pass, tsc/lint clean.

* fix(#4209): depthMeaning accuracy, injection defense on all embedded fields, hoisted prompt write

Batch of Required/Suggestion fixes from the Opus critical-code-reviewer +
writing-for-agents pass:

- CR-02/CR-03: depthMeaning() dropped real categories from quick (empty catch
  blocks, commented-out code) and deep (error propagation, state mutation
  consistency, circular dependencies) relative to the real <depth_levels>
  block, and had zero test coverage. Restored full accuracy and added tests
  that read the real agents/gsd-code-reviewer.md file directly, so drift
  between the two can't recur silently. Unrecognised depth now normalizes to
  standard's definition, matching that agent's own documented rule, instead
  of rendering an undefined bare label.

- RQ-04: depth/baseSha/repoRoot/runDir land in the same markdown prompt
  `paths` does, but weren't checked for control characters like paths were
  (agy-F1's original finding). Hoisted CONTROL_CHAR to module scope and
  applied it to all four fields at the same provenance-check boundary.
  runDir previously had zero validation at all.

- S1: deleted the dead `identity` parameter on `invoke` -- the one production
  caller already ignores it, no test read it by name.

- S2: hoisted the shared prompt write above the per-lane loop -- promptPath
  is derived from runDir alone (constant across lanes by construction), so
  writing it once is both correct and cheaper than the per-lane write R1
  introduced earlier this session. Discovered and fixed a real regression
  from the naive version of this hoist: an unguarded throw would have
  escaped dispatchReviewerLanes as an uncaught exception instead of a clean
  per-lane failure. Added a new PROMPT_WRITE_FAILED whole-dispatch reason,
  matching the existing validatePaths/MISSING_PROVENANCE halt pattern, with
  a dedicated regression test.

- S3: moved `planned = true` past the budget-overflow gate, so `dispatched`
  only reports true once a lane has cleared BOTH plan and budget checks.

- S5: relayed gsd-code-reviewer.md's own "performance issues are out of
  scope unless also correctness issues" policy into the external-lane
  prompt, which previously had no such guidance and could return findings
  the internal reviewer's own contract excludes.

- RQ-05 (partial): shrunk this file's own header docstring's restatement of
  the trait-reuse architecture to a pointer at
  gsd-core/references/loop-hook-dispatch.md, the canonical home.

234/234 tests pass across the full reviewer-lane test suite, tsc/lint clean.

* fix(#4209): dedupe roster-merge logic, consolidate trait architecture prose, add step completion criterion

RQ-02: added a `review-lane explicit-from-argv` subcommand that reuses the
SAME merged-roster logic (`laneBySlug`) `dispatch-step`/`plan`/`invoke`
already share. code-review.md's ~18-line inline `node -e` reimplementing
`loadRegistry`+`mergeReviewerLanes` (a rename-only copy of the block in
gsd-tools.cjs) is now a single call to this subcommand -- the exact
violation code-review-flags.cjs's own header warns against ("this is the
canonical flag-parsing surface -- do not replicate inline bash parsing").

RQ-03: an empty --cap-id XOR --point now warns distinctly from the
legitimate no-context opt-out (both absent) -- a caller that named a
capability without its point was silently indistinguishable from a correct
opt-out. Also hardened the CODE_REVIEW_POINT config-get fallback: it only
ever fires when the config-get COMMAND ITSELF fails (config-get already
resolves the manifest's own schema default in the normal case), but that
failure was previously silent.

RQ-05/W-01/W-12/W-13: the "supportsReviewerLanes is a reusable trait
resolved inside dispatch-step" explanation was restated in full in 5
places across this session's own review cycles. Consolidated to ONE
canonical statement in gsd-core/references/loop-hook-dispatch.md; the other
4 (this file's own header, gsd-tools.cjs's comment, docs/ARCHITECTURE.md,
code-review.md's step-opening comment) now point at it instead.

W-05/W-06: loop-hook-dispatch.md described "false or non-boolean" as two
inert cases when capability-validator.cjs already rejects non-boolean at
load -- restated as the two cases that actually reach this code. Removed a
"do not hand-roll trait resolution" prohibition whose target no longer
exists once the positive description precedes it.

W-04: deleted a no-op sentence in agents/gsd-code-reviewer.md ("missing
block means proceed as normal") -- an absent optional block already means
proceed as normal without being told.

W-08/W-09: replaced longhand "zero selection/plan/invoke calls" and the
made-up compound "byte-for-behavior [un]changed" with the token this
session's own docs already coined for this concept (inert) and the word
that means what byte-for-behavior was reaching for (unchanged).

W-10: dispatch_reviewer_lanes had no completion criterion -- added one
sentence naming the checkable end state (EXTERNAL_EVIDENCE_BLOCK is set,
either populated or empty). This exact sentence would have caught the
cross-fence bug fixed two commits ago at authoring time.

Declined from this round, with reasoning: W-02/W-03 (trim the
untrusted-evidence restatement in EXTERNAL_EVIDENCE_BLOCK/critical_rules) --
two tests deliberately lock this as intentional adjacency-based
prompt-injection defense-in-depth, not accidental duplication (see this
branch's own earlier commit). S4 (wrap LANE_RUN_DIR in a creation-site
`trap ... EXIT`) -- would fire at the end of the CREATING fence, before
spawn_reviewer's agent ever reads the evidence files, given this file's own
documented fenced-block execution model; the existing named cross-reference
between creation and cleanup already satisfies the co-location concern
without introducing that regression.

853/853 tests pass across the full reviewer-lane test suite, tsc/lint clean.

* fix(#4209): merge CODE_REVIEW_POINT into dispatch_reviewer_lanes' one fence, stop test from spawning real codex

Round-5 review (agy) found the same cross-fence-split bug CR-01 already fixed
for EXPLICIT_JOINED/EXPLICIT_REVIEWER_SLUGS: CODE_REVIEW_POINT's config-get
fallback lived in an earlier, separate fence from the fence that consumes it
via --point, split only by prose (not a guard, per this step's own documented
rule). Merged into the single continuous fence and added a structural test
asserting exactly one bash fence in the step.

The new end-to-end regression test for this used --codex, which drives the
fence's real `review-lane dispatch-step` call and, with the codex binary
present on PATH, spawns the real external CLI — which then blocks on
interactive auth with no stdin (BL-01). Stubbed gsd_run for
`review-lane dispatch-step` only (captures argv instead of executing),
keeping the real config-get/explicit-from-argv calls the test is actually
about.

* fix(#4209): split control-char vs missing provenance reason, realpath-check path escapes, stale comment

Round-5 review (Opus) warning-tier findings:

- WR-04: MISSING_PROVENANCE covered both "field absent" and "field present but
  a control-character injection attempt" — a caller distinguishing a config
  problem from a security event couldn't tell them apart. Split into
  MISSING_PROVENANCE (absent) and INVALID_PROVENANCE (present but invalid).
- WR-05: validatePaths' containment check was lexical only (path.resolve),
  so a symlink whose own path sits inside repoRoot could still point outside
  it. Added an fs.realpathSync check (ENOENT-tolerant — a git-diff path can
  legitimately name a file already deleted in a stale worktree), realpathing
  repoRoot itself too so a symlinked repoRoot (e.g. /tmp on macOS) doesn't
  false-positive-reject its own real children.
- WR-08: a comment in the per-lane loop still said a throwing writePromptFile()
  was caught there — stale since the prompt write was hoisted above the loop
  in an earlier round.

WR-03 (validate depth against the quick/standard/deep enum) was considered
and declined: this dispatcher is deliberately capability-neutral (see the
existing "synthetic step context" test, which passes a non-code-review depth
label on purpose to prove no code-review-specific special-casing exists).
WR-01 (double registry load), WR-02 (trim-vs-hard-fail budget semantics), and
WR-07 (reason omitted on the aggregate return) were verified against source
and are not bugs — see review notes.

* docs(#4209): document LANE_RUN_DIR's early-exit trade-off as accepted, not a gap

Round-5 review (Opus, BL-03) flagged that an early exit between
dispatch_reviewer_lanes and commit_review leaks the run-scoped temp dir. A
trap-based cleanup was considered and rejected: if a step genuinely runs as
a separate process, a trap set at creation time would fire at the end of
that SAME fence, deleting the directory before spawn_reviewer/commit_review
ever read it — worse than the leak it would fix.

review.md's own gather_context/cleanup pair for the identical resource class
(a run-scoped reviewer temp dir) already makes and documents this exact
trade-off: cleanup runs only on a documented success path, and a leftover
$TMPDIR entry is explicitly called cheaper than destroyed evidence. Recording
that precedent here so this isn't re-raised as a live gap in a future review.

* fix(#4209): register the WR-05 symlink-escape test's synthetic docs/ path

reviewer-step-dispatch.test.cjs's "capability-neutral reuse" fixture passes
paths: ['docs/spec.md'] as a synthetic, never-read path proving the
dispatcher has no code-review-specific special-casing. lint-docs-guard-
registration correctly flagged this as an unregistered docs/ path reference —
add the docs-guard-exempt marker and its pinned baseline entry, the same
pattern every other synthetic docs/ literal in this test suite already uses.

* fix(#4209): backfill changeset pr: field with the real upstream PR number

changeset-lint's fail_pr_field_drift caught the fragment still pointing at
the fork PR (17) instead of the upstream one (open-gsd/gsd-core#4323) this
branch is now also open against.

* docs(#4209): amend ADR-2782 for the supportsReviewerLanes step-trait seam

trek-e's review (2026-09-07, gsd-core#4323) found a real ADR gap: every
decision in ADR-2782 (D1-D9) and every prior dated amendment governs the
`role: "reviewer"` capability body and its one consumer, /gsd:review. This
PR's actual new seam - a `supportsReviewerLanes: true` trait on an ordinary
feature capability's `steps[]` entry, projected through loop-resolver.cts
and resolved in-process via resolveActiveHooksForPoint - is a different
capability axis (steps/gates/contributions) that the ADR's own scope note
explicitly places out of reach. Per docs/contributor-standards.md's
"Amending an accepted ADR", an in-place dated section is the established,
lighter-weight path for an addition that stays within the ADR's existing
decisions - used twice already in this same file - so this appends a third
dated entry documenting the new seam, its consumer, and why it reuses the
existing D1-D9-governed plan/invoke machinery rather than adding a second
one. No decision is reversed; no new Amends/Amended-by pair is needed since
the steps/gates/contributions axis already carries reciprocal links to
ADR-857 and ADR-894.

* fix(#4209): close two test-quality gaps trek-e's review found

Minor 1: validatePaths (a path-shape parser guarding the prompt-
injection/path-traversal trust boundary) had only example-based coverage,
violating ADR-456's rule that parsers/budget limits carry at least one
fast-check property test. Adds three: safe-segment paths are never
rejected, a single leading "../" always escapes the one-segment repoRoot,
and a control character anywhere is always rejected - one property per
rejection reason validatePaths owns.

Minor 2: the budget-overflow check (`estimatedTokens > budget`) was only
ever exercised far below budget or at budget:0 (unbounded), never at the
exact threshold crossing where a `>` vs `>=` off-by-one would hide. Adds
three exact-boundary tests using the real estimateTokens/
buildSourceReviewPrompt the module calls internally, so the resolved
token count is exact rather than approximated: budget == estimate (must
pass), budget == estimate - 1 (must fail), budget == estimate + 1 (must
pass).

Also extracts okPlan()'s fixture timeoutMs into a named constant -
local/no-adhoc-timeout-literal (#4446) landed on next after this branch
was authored and flagged the pre-existing literal on rebase; it is fixture
data for a synthetic plan object dispatchReviewerLanes never waits on, a
distinct class from tests/helpers/timeouts.cjs's real subprocess norms.

* fix(#4209): update docs-guard-registration baseline for the new ADR citation

reviewer-step-dispatch.test.cjs's new fast-check property tests cite
docs/adr/456-test-rigor-architecture.md in a justifying comment (never a
real read). lint-docs-guard-registration fingerprints every docs/ path
string an exempted test file mentions and fails on drift so a human
re-confirms the exemption still holds - re-confirmed, and the baseline is
updated to match.

* fix(#4209): point changeset pr: field at the fork PR for CI validation

changeset-lint's fail_pr_field_drift check compares the fragment's pr:
field against the PR the CI run is actually attached to (GITHUB_EVENT_PATH),
not a fixed target. Rehearsing this branch on fork PR
davdittrich/gsd-core#17 needs pr: 17 to pass that check; the prior commit's
pr: 4323 (the real open-gsd upstream PR number) is correct for that PR but
fails here. Backfill to 4323 happens again, as the last commit, immediately
before the approved push to open-gsd#4323 - never leaving pr: 17 on the
branch that ships upstream.

* fix(#4209): reject promptChannel:none lanes from source-review dispatch

CodeRabbit found a real scope mismatch: coderabbit's lane declares
promptChannel: 'none' and reviews the working tree on its own terms,
fed nothing (review.md:367). Silently dispatching it through
dispatchReviewerLanes would ignore the bounded paths/depth/baseSha scope
buildSourceReviewPrompt promises and let the lane review whatever it
independently sees fit, violating this interpreter's own scoped,
metadata-only contract. Reject before plan()/invoke(), same as an
unresolved slug.

* fix(#4209): scope CONS-02 test to the evidence-block line, not the whole file

CodeRabbit found the whole-file match on workflowContent would still
pass if UNVERIFIED and re-open/reopen appeared in two unrelated parts
of this 1000+-line workflow, proving nothing about the actual evidence
block's contract. Line-filtered via splitLines (not a bare-\n regex
spanning readFileSync content) so this stays CRLF-portable and passes
local/no-unbounded-quantifier and local/no-crlf-fragile-split.

* fix(#4209): guard DISPATCH_JSON substitution and capture its stderr

CodeRabbit found the dispatch-step command substitution unguarded: a
non-zero exit could leave DISPATCH_JSON empty (or halt the step under
errexit with no warning), and the downstream reducer would only ever
report the generic unparseable_dispatch_output reason, discarding the
command's own diagnostic. Guarded like the existing CODE_REVIEW_POINT/
EXPLICIT_JOINED calls above it: capture stderr to a temp file, surface
it in a warning on failure, and fall back to a parseable dispatch_
command_failed JSON stub so the reducer's existing reason-reporting
path still fires.

* docs(#4209): fix byte-for-behavior wording and missing colon, regenerate

CodeRabbit found "byte-for-behavior" should read "byte-for-byte" (the
established repo term for output-identical unchanged behavior) and a
missing colon after the bold "Optional external reviewer lanes (#4209)"
lead-in in docs/features/code-review-pipeline.md. Fixed in the two
hand-authored sources (commands/gsd/code-review.md, docs/features/
code-review-pipeline.md) and regenerated the two derived projections
(skills/gsd-code-review/SKILL.md via gen-plugin-skills.cjs, docs/
FEATURES.md via gen-features.cjs) so they stay in sync.

* fix(#4209): drop the fabricated DISPATCH_JSON fallback stub (Windows CI)

The prior fix's fallback `DISPATCH_JSON='{"ok":false,...}'` embeds
double-quoted JSON keys inside a single-quoted shell literal. That
extra quote density, inside an already quote-heavy ~8KB driver string,
passed bash -n and the full local suite on Linux but broke Windows
Git-Bash: `dispatch_reviewer_lanes computes CODE_REVIEW_POINT ... end
to end (#4209 round 5)` failed on two Windows CI shards with `bash -c:
unexpected EOF while looking for matching '''` — a Windows argv-to-
command-line re-quoting edge case, reproducible on rerun, not a flake.
Root-caused via gh api job logs plus a byte-identical local
reconstruction of the test's own driver script.

Fix: drop the fabricated stub. The downstream node -e reducer already
falls back to reason `unparseable_dispatch_output` on any JSON.parse
failure, so an empty/partial DISPATCH_JSON on command failure is still
handled correctly, with zero new quoting risk.

* revert(#4209): drop the DISPATCH_JSON stderr-guard nitpick (Windows CI)

Two materially different mechanisms for the same CodeRabbit Nitpick
("Trivial | Quick win") both broke Windows Git-Bash reproducibly:
a single-quoted JSON-literal fallback ("bash -c: unexpected EOF ...
matching '''") and, after removing that, a plain `head -1 "$VAR"`
inside a nested command substitution ("unexpected EOF ... matching
'"'"). Both passed bash -n and the full local suite on Linux every
time; both failed the SAME test deterministically on Windows CI. Two
attempts at the same class of fix (nested-quote construction near
this exact step) is the retry limit - reverting to the original,
already-shipped, Windows-verified unguarded form rather than
continuing to guess at a third quoting mechanism for a Trivial-
severity nitpick. Logged as bug-221/bug-222 in .wolf/buglog.json for
anyone attempting this again: the fix belongs outside this specific
markdown-fence-driver test harness (e.g., a real .sh helper script)
if it's worth doing at all.

* fix(#4209): backfill changeset pr: field to the real upstream PR before push

Fork validation (davdittrich/gsd-core#17) needed pr: 17 to satisfy
changeset-lint's PR-number check while rehearsing there; this is the
last commit before the approved push to the real upstream PR
(open-gsd/gsd-core#4323), so the field points at that PR number again.

a0f8f956c4 enhance(#4139): Phase 3 — partition rules + the five checks (#4497)
* enhance(#4139): Phase 3 — partition rules + the five checks

ADR-4139 Decision 5, epic #4139 Phase 3. Issue #4403's own "Proposed behavior"
section lists four checks; the ADR's Decision 5 and its own phase table ("partition
rules + the five checks") list five — the same four plus "boundary moves are
declared, ongoing". Same issue-vs-ADR drift Phase 2 hit on the detail.md vs
detail/*.md layout: the ADR is the locked, reviewed document, so it wins. This PR
implements all five.

docs/PARTITION-RULES.md (new) is the partition-rules document: the partition rule
itself, the protected-content list and <!-- gsd:protected --> sentinel syntax
(relocated unchanged from gsd-core/references/compact-content-protected-content.md,
now deleted — it was never referenced by any runtime workflow Read, only by the
predecessor test as documentation, so nothing at runtime regresses, and removing it
from gsd-core/references/ also drops it from all 19 installed-project shipped-content
trees for a file nothing ever read), and the five checks explained for a human
reader. Referenced from a new CONTRIBUTING.md subsection under "Editing shipped
content".

tests/helpers/compact-content-split.cjs (new) is the shared mechanics: split
discovery (any gsd-core/workflows/<name>/detail/*.md paired with <name>.md — no
registry file, a pair is registered by existing on disk), line normalization
(carries forward Phase 2's bare-label-line isTrivial fix and the canonical
gsd_run-launcher-preamble exclusion), sentinel extraction, and a
Boundary-Move-Declared commit-trailer reader that is a direct structural port of
tests/helpers/emitted-runtime.cjs's Emitted-Drift-Ack-Hash/-Growth trailer reader
(ADR-3942) — same merge-base range, same fail-closed throw on an uncomputable range,
same dedupe/conflict rules.

tests/compact-content-partition-guard.test.cjs (new) is the actual guard, superseding
tests/plan-phase-compact-split.test.cjs (deleted — its per-pair checks are now the
general guard's job for plan-phase specifically). Checks 2 (disjointness) and 3
(registration + size cap) run unconditionally against every registered split. Checks
1 (completeness, fires once per split on the PR that introduces a new detail/ path),
4 (protected content — no trailer can ever excuse this one, unlike check 5) and 5
(boundary moves declared) are PR-diff-scoped against the resolved base ref and skip
cleanly when there's nothing to compare (a fresh clone, no PR in flight) — a
deliberate asymmetry from check 5's trailer reader, which must throw rather than
silently pass when ITS range is uncomputable, since that function is answering "did
this PR declare its moves" rather than "is there even a diff to look at". Each of the
five checks carries a RED (deliberately broken fixture) / GREEN (fixed) test pair,
built against synthetic temp files or real throwaway git repos, per this repo's rule
that a guard nobody has seen go red is not yet a guard. Building the real fixtures
caught and fixed one real bug before it shipped: check 4's line-presence test was
using the trivial-line-filtered normalizer, so a byte-identical spine falsely
reported its own protected code-fence line as "deleted" — fixed with a
non-filtering membership check.

Extending docs/INVENTORY.md's "Workflow Sub-Files" table for `detail` surfaced a
pre-existing, unrelated gap in the SAME area: gsd-core/workflows/<name>/templates/*.md
is a fourth workflow sub-file kind that already existed on disk and was already known
to lint-response-language-coverage.cjs's FRAGMENT_DIRS, but was invisible to
gen-inventory-manifest.cjs and undocumented in that table. Fixed alongside it, same
pattern, same PR, rather than deferred.

Also, mechanically required by the new fourth sub-file kind:
- scripts/lint-response-language-coverage.cjs: `detail` added to FRAGMENT_DIRS
  alongside modes/steps/templates — a detail/<part>.md inherits its parent's
  response_language coverage through the same per-file proof, not a parallel one.
- tests/workflow-size-budget.test.cjs: explicit regression test locking that
  detail/ files are governed solely by the hard, non-waivable NEW_FILE_CAP
  (tests/helpers/emitted-diff.cjs) and never by the XL/LARGE/DEFAULT spine tiers —
  true by construction (measureWorkflows/listWorkflowStems don't recurse), made
  explicit per the issue's own Done-when item rather than left true-by-omission.
- scripts/gen-inventory-manifest.cjs: `workflow_detail` and `workflow_templates`
  NESTED_FAMILIES entries; docs/INVENTORY-MANIFEST.json regenerated
  (plan-phase/detail/elaboration.md, discuss-phase/templates/*.md now tracked);
  docs/INVENTORY.md's table updated to four kinds.

Verified: `npm run lint:ci` clean with the eslint cache cleared.

* fix(#4403): review findings + a real gsd-test failure in the new guard

Two orthogonal review passes (Standards + Spec, isolated sub-agents) plus a
separate security review ran against the prior commit. Fixed everything each
surfaced:

- Security (Low, path-traversal existence oracle): checkRegistration's
  dangling-reference check extracted detail-path-shaped substrings from spine
  PROSE via a regex that permits `.`/`/` freely, then joined them onto repoRoot
  and probed fs.existsSync with no containment check — a spine file containing
  `../../../etc/detail/passwd.md`-shaped text could make the guard test file
  existence outside the repo. Added a path.relative-based containment check
  before the fs.existsSync call; anything that resolves outside repoRoot is now
  reported as a dangling reference directly, never probed on disk.
- Standards (Boundary Coverage): the size-cap fixtures covered NEW_FILE_CAP and
  NEW_FILE_CAP-1 but not NEW_FILE_CAP+1 — added the third boundary-point case
  CLAUDE.md's TEST RULES require (limit-1/limit/limit+1).
- Standards (Property-Based Testing): extractProtectedBlocks (a sentinel
  parser) and the new parseBoundaryMoveTrailerValues (a declare/dedupe/conflict
  parser, bijective-shaped) had no fast-check property test. Added three: a
  render/parse bijectivity property for the trailer parser (mirroring the exact
  ADR-3942 sibling test's alphabet/idiom), a dedupe-is-idempotent property for
  the same parser, and a well-formed-sentinel-round-trips property for
  extractProtectedBlocks.

Then dispatched gsd-test on the resulting commit. It found a real bug the
reviews couldn't have caught (none of them can run inside gsd-test's sandbox):
checks 4/5's real-repo assertion failed against plan-phase's own split,
reporting DISK_PLANS/#3218-comment lines as "undeclared boundary moves" —
content Phase 2 (#4402) legitimately moved into detail/elaboration.md months
before this PR's Boundary-Move-Declared mechanism existed to require a
trailer for it. Root cause: `resolveBase()`'s own doc comment already documents
that no `origin/*` remote-tracking ref exists inside the gsd-test sandbox
container, and its fallback candidate (a bare `next` branch) can resolve to a
point in history that predates an already-merged, already-reviewed split —
making that split look "newly introduced" from the sandbox's vantage point.
Check 1 (completeness) already scopes itself correctly to only genuinely-new
detail paths (git diff status 'A'); checks 4 and 5 did not share that scoping,
so a stale base made them re-litigate a settled split retroactively. Fixed by
having checks 4/5 skip any split name check 1 already counted as newly-split —
their own premise ("did an EXISTING split shed/undeclare something") does not
apply to a split that is, from the resolved base's vantage point, brand new;
that is check 1's domain alone. Verified locally (25/25 tests pass via a
direct `node -e` require, since `node --test` is blocked in this repo) and via
re-reasoning through the exact real-repo scenario the gsd-test failure showed.

Also regenerated all 19 tests/fixtures/install-tree/*.json goldens — the
prior commit's deletion of gsd-core/references/compact-content-protected-content.md
was never reflected there, which is what golden-install-tree.test.cjs's other
19 failures in the same gsd-test run were.

* docs(#4403): backfill changeset pr number to 4497

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

* fix(#4403): isolate codex-config.test.cjs into its own chunk, root-causing the Windows CI failure

PR #4497's "full test (windows-latest, 24, shard 2/3)" job failed: run-tests
killed chunk 3/8 at the 600s per-chunk backstop, with codex-config.test.cjs
(weight 17.87, by far the chunk's dominant cost) packed alongside 39 other
files. Traced, not assumed:

- scripts/run-tests.cjs's own timeout-headroom comment for the OUTER
  per-shard timeout documents that "adding one test file reshuffled 115 of
  268 unit files between shards" — shard/chunk composition is architecturally
  known to be unstable to single-file additions, which is exactly what this
  PR's own new tests/compact-content-partition-guard.test.cjs is.
- A second comment, dated 2026-09-06 (one day before this PR, PR #4428's own
  CI), already documents the SAME chunk hitting the SAME 600s backstop with
  the SAME file (codex-config.test.cjs, "a genuinely MEASURED weight of
  17.87 — not a stale-table miss") dominating it — the fix then was cutting
  the Windows per-chunk budget from 60 to 40. That cut clearly was not
  enough: two documented incidents in two days, at two different budget
  settings, both centered on one file that alone consumes ~45% of even the
  reduced Windows budget.
- tests/test-timings.json's own header confirms its source data
  (test-events-linux-node22/24.jsonl) is Linux-only, and run-tests.cjs's own
  chunk-timeout diagnostic already prints "real Windows cost runs ~2.2x the
  recorded figure" — the packer's weight-balancing is working off data that
  is both stale (table last regenerated 2026-08-07) and known to
  underestimate the platform where the failure occurs.

Given codex-config.test.cjs is disproportionately heavy AND every companion
sharing its chunk is decided by a packing algorithm already documented as
reshuffling unpredictably on any new file, tuning the shared budget a third
time only moves the marginal line to wherever the next new file happens to
land — it does not remove the gamble. Isolating codex-config.test.cjs into
its own dedicated single-file chunk, unconditionally and on every platform,
removes it at the source: the file never enters the pool packChunks balances,
so no other file's packing changes, and no future single-file addition
(mine or anyone else's) can silently reintroduce this exact failure by
landing in its chunk.

Extracted as a small pure function, partitionIsolatedFiles (mirroring this
file's existing pattern of pulling packing/analysis logic out of main() for
in-process unit coverage — see computeSweepProtectSet, analyzeChunkEvents),
with 6 new tests in tests/run-tests-harness.test.cjs covering basename
matching across path separators, near-miss non-matches, the empty-list case,
and the isolated-set contents.

Root cause is now closed rather than papered over with a retry: this failure
is a property of one specific heavy file's chunk placement, not something
that recurs randomly. If codex-config.test.cjs itself is ever genuinely sped
up, this isolation can be revisited — this is a packing-side mitigation for
a known file's cost, not a claim the cost is irreducible.

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.

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.

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

* 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.

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.

* 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;

* 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-
assertion warnings in files this PR does not touch); node

* 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
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

* 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.

* 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.

* 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`

* 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
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

* 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:
 src/planning-workspace.cts | 17 ++++++++++++-----
 1 file changed, 12 insertions(+), 5 deletions(-)

* 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

* 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).

80de48c319 enhance(#3914): every phase records a truthful guard ledger (#4018)
* fix(#3914): retire n/no-process-exit where its successor governs

Epic #3889 criterion 5 — no phase closes with a guard added and its
predecessor left standing — is violated in the tree by the epic that wrote it.

local/require-registered-exit was registered on gsd-core/bin/**/*.cjs and
scripts/**/*.cjs, while n/no-process-exit stayed 'error' over a nine-glob block
covering those same two. Only the hooks 'off' exemption ever came down; the
predecessor's registration never did. Both rules have been enforcing the same
property on the same surfaces since P6.

Narrowed, not deleted. Seven of those nine globs have NO successor —
eslint-rules/, bin/lib/, pi/, examples/, vscode/, .kilo/, .opencode/ — so
deleting the rule outright would silently drop enforcement on all seven. That
is the inversion this epic has already hit three times: removing a coarse guard
because a narrower one exists somewhere it does not reach. Flat config is
last-match-wins and both successor blocks come after the nine-glob block, so
'n/no-process-exit': 'off' in exactly those two retires the predecessor
precisely where the successor governs and nowhere else.

The successor is strictly more precise: it permits process.exit only inside
terminateNow in cli-exit.cts, the single sanctioned terminator (ADR-3889 §3),
where n/no-process-exit permits none and would flag terminateNow's own
generated copy.

Asserted at the consumer's altitude via ESLint.calculateConfigForFile on real
paths, with the positive control that matters: n/no-process-exit is still
'error' on six of the seven successor-less globs, so a future edit that turns
this into a blanket disable goes red. bin/lib/ has no file in this checkout and
is reported as untested rather than given an invented path. Severity is
normalized across the string/numeric/array forms the API can return, and the
normalized value asserted — not truthiness.

Verified by running calculateConfigForFile myself on both superseded globs and
four controls before trusting the test.

Found and fixed inline: the change made an eslint-disable directive at
gsd-tools.cjs:257 partially unused, which --max-warnings 0 rejects; narrowed to
the one rule still in force.

Verification runs on the remote runner.

Refs #3914

* docs(#3914): the epic added three guards, it did not remove one

The audit reconciled the epic ledger against what actually landed. The net is
+3, not -1: four lint:generated-sync --check arms (gen-scripts-cli-exit,
gen-hooks-cli-exit, gen-exit-code-registry, gen-exit-code-docs) plus one rule,
against two retirements.

An epic whose thesis was consolidation ended with a larger guard surface than
it started with. The additions are each defensible; the claim that the total
fell was never true.

Two of the three prior errors in this amendment are mine. It said "Net -1 by
count" above terms reading -1 -1 +1 +1 +1, which sums to +1 — an arithmetic
error in the paragraph directly below the sentence arguing that an ADR about
honest accounting must not pad its own ledger. And the term list omitted two of
the four --check arms, which is what turns that +1 into the real +3.

Recorded rather than quietly rewritten. This ledger has now been wrong three
times — the original -2, the -1 that replaced it, and #3914's own table, which
states -1 above terms summing to 0 — and a written claim nobody checked against
the thing it describes is the exact failure this epic exists to close.

Refs #3914

* fix(#3914): make the successor actually supersede before retiring the predecessor

An isolated security review found that the previous commit turned off a guard
that was still doing work. Reproduced by executing both rules against a
fixture, not inferred:

  const exit = 'exit';
  process[exit](1);

n/no-process-exit flags it; local/require-registered-exit did not, because it
early-returned on callee.computed. So retiring the predecessor on
gsd-core/bin/**/*.cjs and scripts/**/*.cjs un-guarded that shape on precisely
the two globs this epic's exit contract cares most about.

This is the third time in this epic I have removed a coarse guard on the claim
that a narrower one covered it, without checking construct-level parity — after
the allowlist key-to-prefix-to-exact-membership sequence and the band
ranges-to-categories one. The rule is the same every time: a narrower guard
supersedes a coarser one only where it demonstrably reaches at least as far,
and "demonstrably" means executing both against the constructs, not reading
either.

The successor now resolves computed property access for the statically
determinable cases — a string Literal, and an Identifier bound once to a string
Literal, resolved through scope — and leaves genuinely dynamic properties
alone so the rule does not over-fire. Measured after the fix: plain
process.exit flagged, process['exit']() flagged, process[exit]() flagged,
process[globalThis.k]() not flagged. That makes it a strict superset of the
predecessor on these globs, since process['exit']() was caught by NEITHER rule
before.

The second finding is worse than the first, because it was reasoning rather
than oversight. My justification comment claimed n/no-process-exit "would flag
terminateNow's own generated copy here". It would not — that file is in the
global ignore list, so neither rule ever lints it. There was no conflict to
resolve; I wrote a rationale I had not checked, in a change whose entire
subject is written claims nobody verified. Both comment blocks now state the
real basis.

The tests that should have caught this asserted only rule SEVERITY per glob and
never construct REACH, which is exactly how a coverage hole passed. A parity
matrix now pins all five shapes, including a RED/GREEN regression pin against
an inlined reproduction of the pre-fix rule — inlined rather than loaded from
HEAD, because HEAD resolves to the fixed commit under the remote runner and
would silently stop testing anything.

Verification runs on the remote runner.

Refs #3914

* fix(#3914): the two exit rules are complementary — keep both

Reverts this branch's retirement of n/no-process-exit. The premise was wrong
twice, and the second review proved the change itself was wrong.

I claimed local/require-registered-exit was a strict superset on
gsd-core/bin/**/*.cjs and scripts/**/*.cjs. Measured, successor vs predecessor:

  function f(exit) { process[exit](1); }         0  vs  1
  let exit='exit'; exit='exit'; process[exit]()   0  vs  1
  const { exit } = ...; process[exit](1)         0  vs  1

plus for-of bindings, let-then-assign, var redeclaration, catch params, and an
undeclared global named exit. The predecessor matches any identifier NAMED
exit however it is bound; the successor resolves only a string literal or a
single-write const. It never was a superset — I asserted the relationship after
fixing one construct and did not re-check the rest.

The justification was independently false: all three generated cli-exit copies
are in the global ignore list, so n/no-process-exit was never flagging
terminateNow. There was no conflict to resolve. I wrote a rationale I had not
verified, in the phase whose subject is written claims nobody checked.

So criterion 5 does not apply to this pair. They are not predecessor and
successor — they are complementary, each catching constructs the other misses.
The epic's criterion assumed a replacement relationship that does not exist
here, and retiring either rule loses real coverage. The ADR ledger now says so
with the measured shapes.

What survives is the genuine improvement: the computed-property strengthening.
local/require-registered-exit now catches process['exit'](1) and optional-chain
terminators like process?.[k]?.(1), which NEITHER rule caught before, while
correctly ignoring a genuinely dynamic property so it does not over-fire.

The parity tests are rewritten to assert what is true rather than what I wanted
to be true: a bidirectional matrix where each rule is shown catching shapes the
other misses. The previous matrix tested only the four shapes where the
successor wins, which is precisely why the regression shipped — a test set
selected to confirm the thesis.

Also corrected: a stale ADR sentence claiming a third wrong ledger version that
does not exist (the table it described now reads +3 over terms summing to +3),
and a changeset whose stated motivation was the false generated-copy conflict.

Verification runs on the remote runner.

Refs #3914

* fix(#3914): the exemption term was a no-op — the net is +4

Fourth correction to this ledger, and a fourth error of the same kind.

Every version counted removing the n/no-process-exit 'off' entry from the hooks
block as -1. Measured: calculateConfigForFile returns undefined for that rule on
hooks/**. It was never registered there, and no broader block sets it globally,
so the 'off' entry overrode nothing and removing it changed no enforcement at
all. A no-op removal, not a guard removal — the same category error as counting
baseline acknowledgement entries: a thing that is not a guard, in guard units.
It is misattributed too; that block came down in d98b55562 (#3910), already on
next before this branch existed.

So the epic added FOUR guards, not three.

This surfaced from a test of mine that overclaimed. I asserted n/no-process-exit
was error on "all nine CommonJS/hook globs" — but hooks is not one of the nine,
and the rule resolves to undefined there. Fixing the test to match reality is
what exposed the ledger term, which is the argument for tests that assert
identity rather than a comfortable shape.

The hooks state is now pinned explicitly rather than glossed: n/no-process-exit
unregistered, local/require-registered-exit error. It is mildly surprising and
therefore worth a test.

Also updates a pre-existing test that documented the old name-based-only
boundary as intentional. The computed-property strengthening deliberately moves
that boundary — process['exit'](0) was caught by NEITHER rule before — so the
test now asserts the new contract and cites the ADR, rather than being left to
fail or the rule weakened to satisfy it. A contract change should read as
deliberate in the test that pins it.

Verification runs on the remote runner.

ac7587287b fix(#3812): document how Current Position actually resolves a duplicate field (#4017)
* docs(#3812): say that Current Position is single-valued, and pin the behavior that makes it true

#3812 shipped CLOSED with half its acceptance unmet. #3873 delivered cardinality for FRONTMATTER
keys - current_phase/current_plan render as optional at docs/reference/state-md.md:89,91, covered by
tests/gen-state-md-docs.test.cjs:374. The issue's actual ask was the ## Current Position BODY
section, and that never landed. Surfaced by an /adr-phase-coverage audit of epic #3473; the issue
was reopened rather than noted.

The section now states three things: every field is single-valued, the section is overwritten rather
than appended to, and a duplicate resolves to the FIRST occurrence with no warning - so a line
appended in good faith is silently ignored rather than winning. Progress history belongs in
## Performance Metrics, two headings down, and the text now points there.

The third claim is a behavioral promise about the reader, so it was VERIFIED BY EXECUTION before
being written rather than inferred from the issue title:

  stateExtractField(<"Phase: 1 of 5 (First)" ... "Phase: 9 of 9 (Appended later)">, "Phase")
    -> "1 of 5 (First)"

The mechanism is state-document.cjs:405 - the plain-line pattern ^<field>:[ \t]*(.+) carries flags
im with NO g, so String.match returns the first hit. Writing "first wins" without running it would
have repeated the exact error I had to retract twice in this epic already.

A test pins the reader, not the prose. Three rows in tests/state.test.cjs: T1 (load-bearing) asserts
the duplicated case resolves first; T2 asserts the ordinary single-field case still works, so a fix
that only functions when duplicated cannot pass; T3 puts a Plan: line BETWEEN the two Phase: lines
and asserts it resolves independently - negative space, because a reader returning the first line of
the SECTION rather than the first matching FIELD would satisfy T1 alone. Proven to discriminate: a
last-match variant returns "9 of 9 (Appended later)" and T1 reds.

No assertion checks that the document contains a sentence. That is what local/no-source-grep exists
to stop, and it would pin wording that is allowed to improve. The point of the test is that if that
regex ever gains g and a last-match walk, the test fails - instead of the documentation quietly
becoming a lie with nothing to notice.

Prose only, no new heading. docs-state-md-locale-parity compares heading-level sequences by LCS
rather than text, so added paragraphs cannot fail it while an added HEADING would fail all four
locales. The constraint is structural, not stylistic - confirmed by running that comparison after
the edit.

The four locale copies are translated rather than left stale. They are not gate-enforced for prose,
so "nothing fails" was available and is not the same as correct: leaving four documents asserting
something the English one now contradicts is a correctness problem. Code spans and the anchor link
stay untranslated - they name real tokens.

The whole approach rests on one fact, checked first: ## Current Position at :196-208 sits OUTSIDE
every generated marker region (:81-104, :138-151), so a hand edit survives --write. Re-confirmed
after all five edits - gen-state-md-docs --check reports all 6 targets up to date. Had that been
false the fix would have belonged in the generator, and a hand edit would have been silently
reverted.

One real gate failure fixed inline rather than reported: the new test's comments referenced
docs/reference/state-md.md, which was not in that file's registered exempt-docs paths, and
lint-docs-guard-registration failed lint:ci correctly. Registered.

Known limit, named rather than folded in: gsd-tools validate/health still do NOT warn on a
duplicated Phase:. #3812 records that as a "consider", not a requirement, and confirms none of the
nine rules in src/health-diagnostic-rules/{state-consistency,phase-structure}.cts counts
occurrences. Documenting the silent first-match is the delivered scope; making it loud is new scope
and stays unclaimed.

Closes #3812

* docs(#3812): the rule I documented was false — replace it with the measured one

An isolated review returned two blockers. Both mine, and the first is the worse
kind: I wrote a falsifiable rule into a reference page and got it wrong.

1. "A duplicate resolves to the FIRST occurrence" is FALSE.

   stateExtractField (src/state-document.cts:401-419) tries BOLD `**F:**` across
   the whole input, THEN plain `^F:`, THEN a pipe-table row. Form precedence
   beats document order. Measured against the built reader, all intra-section:

     Phase: A (plain)  /  **Phase:** B (bold, later)   -> B    LATER WINS
       Phase: A (indented) / Phase: B (plain, later)   -> B    LATER WINS
     Phase: A (plain)  /  | Phase | T (table) |        -> A    first wins

   My original verification tested plain-versus-plain, saw first-wins, and
   generalized to all forms. Measuring one case and claiming the general rule is
   the same error I have had to retract twice already in this epic.

   It is also worse than silence. The sentence told authors an appended line is
   safely ignored; a bold line appended "for emphasis" silently overrides the
   original. Someone trusting the doc would have corrupted their own state file.
   And #3812 never asked for a resolution rule - it asked for single-valued,
   overwrite-not-append, and where history goes. The rule was my unrequested
   addition.

   Replaced with the measured truth: resolution is by FORM (bold anywhere, then
   plain at line-start, then table row), and only WITHIN the winning form does
   the first occurrence win. Both consequences stated plainly - a higher-ranked
   form wins regardless of position, and an indented `Phase:` is invisible to the
   plain form. All five claims in the new paragraph verified by execution before
   being written, including the two I had wrong.

2. The tests tested the wrong case and passed for the wrong reason.

   T1/T3 put the second `Phase:` under `## Somewhere else` - the INTER-section
   case, which #2956 already fixed by scoping. #3812 says verbatim that #2956
   "fixed the inter-section case and never addressed intra-section duplication",
   so the case the new prose describes was untested, and the fixtures passed
   because of section scoping rather than field resolution. They also called bare
   stateExtractField rather than the production chain, T2 could not discriminate
   first from last at all, and no fixture mixed forms - which is precisely why the
   false claim survived to review.

   Rewritten as four rows, all intra-section, all through the real
   stateCurrentPositionSlice -> stateExtractField path: plain-then-plain (first
   wins within a form), plain-then-bold (the bold LATER value wins - the row whose
   absence let the false claim ship), indented-then-plain (indented invisible),
   and sibling-field independence. Each proven to fail against a reader that
   disagrees.

3. Two dead anchors. pt-BR and zh-CN linked `#performance-metrics` while their own
   headings are `### Métricas de Desempenho` and `### 性能指标`. Both fixed to the
   anchor their own heading generates. ja-JP/ko-KR kept the English heading, so
   theirs already resolved.

4. A ja/ko sentence inverted its own meaning. Both rendered "which is the section
   designed to grow" with a bare demonstrative whose nearest referent read as
   Current Position - saying the opposite of the point. Rewritten so the clause
   attaches unambiguously to `## Performance Metrics`.

5. Cross-locale drift, flagged by the implementing agent rather than by me: after
   fixing EN, the four locales still stated the OLD false rule. Four documents
   asserting something measured to be wrong is worse than four saying nothing.
   All four now carry a faithful translation of the corrected paragraph, with
   code spans, each file's own anchor, and the ja/ko referent fix preserved.

Verified: all five claims executed against the built reader; every rewritten test
row proven to discriminate; gen-state-md-docs --check reports all 6 targets up to
date, so the edits stay outside the generated marker regions; locale heading
parity unaffected (prose only, no headings added); build:lib, lint and lint:ci all
exit 0.

* docs(#3812): second false rule on the same page — scope the ranking to the section

A second isolated review found a second false falsifiable claim, and the failure
mode is the same one twice in a row:

  attempt 1: verified plain-vs-plain, wrote a claim about ALL FORMS
  attempt 2: verified bare stateExtractField, wrote a claim about THE DOCUMENT

Both times the claim covered a wider surface than what was actually executed. The
fix each time was not a better sentence, it was executing the surface the
sentence describes.

BLOCKER — "bold `**Phase:**` anywhere in the DOCUMENT wins" is false.

  ## Current Position / Phase: 1 of 5   +   ## Archive / **Phase:** 88

    bare stateExtractField(whole doc) -> "88 (other section)"
    PRODUCTION (slice then extract)   -> "1 of 5 (in section)"

#2956's section slice means production never hands another section to the
matcher; a bold line in `## Archive`, or in the YAML frontmatter, is simply not
seen. The ranking is real but scoped: it applies WITHIN `## Current Position`.
I verified against the bare function and wrote a claim about the system.

Every existing test placed its bold line inside the section, which is exactly why
nothing contradicted the claim. T5 now puts a bold `**Phase:**` in `## Archive`
and asserts production returns the in-section plain value, with the unscoped
reader asserted to DISAGREE so the row proves the scoping rather than assuming
it.

BLOCKER — the changeset still shipped the ORIGINAL retracted claim.

I corrected the page and left the release note saying "resolves to the first
occurrence ... a second entry added in good faith is silently ignored". The note
contradicted the page it announces, and the release note is what most people
actually read. Rewritten to the corrected rule.

MEDIUM — the concession was inverted. It read "wins even if it comes FIRST in the
file", which is the vacuous direction; the surprising case, and the one the very
next clause illustrates with an APPENDED bold line, is "even if it comes LAST".
All four locales reproduced the inversion faithfully, so it was an EN-source
defect rather than translation drift.

Two sharp edges now named, both measured: a bold `**Phase:**` followed only by
trailing spaces resolves to an EMPTY STRING and does not fall through to a valid
plain line below (T6 pins it); and `| **Phase:** | 3 of 4 |` short-circuits to the
bold form and returns the literal `"| 3 of 4 |"`. A page that teaches form
ranking has to say where the ranking bites.

Also fixed: all five files labelled the link `## Performance Metrics` while the
heading is `### Performance Metrics`. Anchors resolved correctly everywhere; only
the label's level was wrong.

Every clause in the final paragraph re-verified through the PRODUCTION chain
(stateCurrentPositionSlice -> stateExtractField), clause by clause, before being
written: bold in another section does not win; bold in frontmatter does not win;
bold appended last does win; first wins within one form; trailing-space bold
yields empty. All four locales carry the same corrected rule.

gen-state-md-docs --check reports all 6 targets up to date; heading counts
unchanged at 20/20 across all five files, so locale heading-parity is untouched;
build:lib, lint and lint:ci all exit 0.

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.

c5f2b94b27 enhance(#3907): gates report no-input instead of a verdict they never reached (#3932)
* feat(#3907): gates report no-input instead of asserting a verdict they never reached

The three stdin-reading gates bound 2 to a stdin read error only, with no arm for stdin closed at zero bytes - so empty input flowed into the detector, found nothing, and exited 1, which each module's own comment defines as a negative verdict. An unset PHASE_SECTION made the UI gate assert the phase has no UI. Empty and whitespace-only input now exit NO_INPUT, and a read error exits UNAVAILABLE rather than a locally-invented 2, both resolved through the registry and delivered by terminateNow.

The exit code was only half of it: under --json the same input emitted {detected:false}, byte-identical to the fabricated payload #3909 exists to fix, and the blocking coverage gate reads that payload. Empty input now emits the in-tree {skipped:true,reason} form with no detected key at all.

teams-status is excluded: it never reads stdin and has no invented 2, so the four-module framing in the issue and ADR is wrong. The dead root bin/lib/ui-safety-gate.cjs is deleted - no installer reference, no workflow invocation, and the live fallback chains are for other modules. Its removal restores the unit tests to the module that actually ships; they had been asserting the stale copy's two-field shape, which is why it drifted unnoticed.

* fix(#3907): drive gate tests through the process seam, and make removed-but-needed basename-precise

CONTRIBUTING requires every subprocess go through tests/helpers/process-seam.cjs; two of the three gate suites hand-rolled spawnSync while the third, added in the same change, used runNode correctly for the identical injection case. Converted the blocks this change added, leaving pre-existing ones alone.

Deleting one of two files sharing a basename made lint-removed-but-needed report 14 references that were all to the surviving canonical module - the false-positive class its own docstring names. It now matches on the deleted file's full path when a surviving file shares its basename, which is more precise rather than weaker: a genuine full-path reference still fails, and behaviour is unchanged when no basename collides. It immediately caught a docstring on this branch that spelled the deleted path.

* test(#3907): update the one existing assertion that pinned the old empty-stdin verdict

A pre-existing test asserted exit 1 on empty stdin - the defect this phase removes - and was missed because the change added new blocks without auditing existing ones pinning the old contract. Audited the rest: the other three status-1 assertions in that file all feed real input and are the genuine-negative controls that must keep returning 1, so exactly one was stale. The retired 2 is gone from the describe's contract comment too.

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.

107eb8c1d9 feat(#3753): run docs guards on the PR that changes the docs they read (#3787)
A PR whose diff is entirely under docs/ runs zero tests, so a guard whose INPUT
is shipped prose cannot protect the PR lane of the diffs it exists to check. Its
only firing opportunity is after merge, on the shared branch -- which is how next
went red on dacae9273 while the PR that caused it (#3746) was green on every
check.

The docs-lint job in .github/workflows/docs-required.yml -- an ALREADY-REQUIRED
context -- now selects and runs the docs guards that read the specific docs files
the PR changed.

  scripts/docs-guard-registry.cjs    test file -> the docs paths it reads (63)
  scripts/select-docs-guards.cjs     pure (changedPaths, registry) -> test files
  scripts/lint-docs-guard-registration.cjs   drift guard, wired into lint:ci

scripts/ci-test-scope.cjs is NOT touched -- `git diff origin/next --` on it is
empty -- so #764's saving stands and its 21 pinning tests are untouched.

Selection: exact path; trailing-slash directory prefix (boundary-checked --
docs/adrenaline.md does NOT match docs/adr/, which a naive startsWith gets
wrong); and '*' for the 6 entries that walk docs/ generally or read a computed
path. Unknown maps to '*' -- guessing narrow is how a guard silently stops
running. Measured: a typo fix selects 6 of 63; docs/AGENTS.md selects 12;
docs/COMMANDS.md selects 18.

Four things this got wrong first, each found by an independent reviewer or by
probe, and each having been asserted safe in a comment:

1. The registry started as a RULE in ci-test-scope.cjs's RULES, on the theory
   that classify()'s !codeChanged normalization made it inert. True for
   docs-ONLY diffs; false for MIXED docs+code diffs, where codeChanged is true
   and the normalization never runs:

     node scripts/ci-test-scope.cjs --files "docs/a.md src/semver.cts"
       with the RULE:  25 targeted_tests
       origin/next:     3 targeted_tests

   Category error: RULES is the scoped lane's input; a docs-guard registry is a
   lane manifest for a consumer that never calls classify(). Extracted; pinned
   by value.

2. The second attempt was a dedicated workflow with paths: [docs/**]. Such a
   workflow never reports on a non-docs PR, so it can never be a required
   context without hanging every non-docs PR -- and a non-required check does not
   block a merge, so the guard would have been advisory and #3753 unfixed.
   docs-required.yml already has no paths: filter, already supplies the required
   docs-lint context, already computes docs_changed, and already ran one docs
   guard gated on it. Generalizing that step needs no ruleset edit at all.

3. The registry and the drift lint were built from ONE path-segment heuristic, so
   both were blind identically -- and blind at the guard that motivated the issue.
   The reader-call regex required a character BEFORE its keyword, so a callee
   named exactly read( / load( / parse( / doc( / file( / content( could never
   match; and only an INLINE path.join(ROOT,'docs','X.md') argument was caught,
   missing the two-step-via-variable form -- the MAJORITY spelling -- plus
   template literals and concatenation. Detector 1 fired on 14 of ~450 files, so
   35 genuine guards sat unregistered while the lint reported 0 violations,
   including cursor-reviewer (reads docs/COMMANDS.md, asserts
   .includes('--cursor')) and inventory-headings-countfree. The "accepted blind
   spot" this shipped with was the common case, not a fringe.

4. With detection fixed the true population is 115 files: 63 genuine guards, 52
   incidental. Running all 63 in a REQUIRED check on a one-line typo fix is the
   cost #764 exists to avoid -- install.test.cjs is 7840 lines and reads exactly
   one docs file, docs/AGENTS.md, for its frontmatter. Dropping it reproduces the
   bug; running it for a typo elsewhere is waste. Hence the map.

Then a second review round found six more, all fixed here:

- fragment-single-edit-propagation.install.test.cjs was EXEMPTED as
  "overlay fixture only". False: it reads the real docs/registries/eos.json and
  asserts on a registry entry name, and reads the real ADR-0001 and asserts its
  H1. A docs-only PR touching either would have gone green and red next -- #3753
  shipping again, from inside the fix for it. Now registered against both paths,
  and all 52 remaining exemptions were re-audited one by one.
- The SUITES-collision guard compared RAW registry keys, but run-tests.cjs strips
  a leading `tests/` BEFORE its suite check. So it caught 'all' and missed
  'tests/all' -- the only spelling that can actually occur, since every key
  carries the prefix. One typo would have run all 824 test files inside the
  required job. Now normalized the same way run-tests.cjs normalizes.
- The lint failed OPEN on an unreadable tests dir or candidate file: 0 violations,
  ok:true. A guard that cannot read its input must never report success.
- The exemption ratchet gated identity only, so a baselined file that later
  STARTED asserting on shipped docs stayed exempt silently -- 52 permanently blind
  files. The baseline now fingerprints the docs paths each exempted file
  references and fails when that set changes, naming what changed.
- The exemption marker was still honored inside a multi-line template literal in
  the header window. The scanner now tracks template-literal and block-comment
  state.
- `git diff --name-only | grep '^docs/'` silently dropped C-quoted non-ASCII docs
  paths, making docs_changed=false a green zero-guard check. Both call sites now
  pass -c core.quotepath=false.
- The run step was gated on hashFiles(), which a force-committed
  .docs-guard-tests.txt would satisfy. The step now rm -f's both scratch files
  first and gates on an output it sets itself.

Three empty states, deliberately distinct, because conflating them rebuilds
#3753: an empty or malformed registry HARD-FAILS; docs changed with no guard
covering them logs and skips; no docs change is already gated. The middle state
must never be expressed as an empty --files-from, which prints `no tests in suite
"all"` and exits 0 -- a green check that guarded nothing. With the current
registry that state is unreachable, because the six '*' entries always match;
the branch is kept as defensive handling for a future registry and says so.

timeout-minutes: 15 bounds the required job against a hanging fork-supplied test;
it had none. npm ci was added because the job never installed dependencies -- the
previous single-file step got away without it, the registry does not.

docs/contributing/docs-guard-registration.md documents the rule, following its
sibling cross-platform-portability-rules.md, and CONTRIBUTING.md's CI Test
Quality Checks table links to it. It is also load-bearing: without a docs/ file
in the diff this PR would not have triggered its own lane, shipping an
unexercised change to a required check.

One unrelated fix, included because this PR surfaced it and CLAUDE.md forbids
deferring a defect found while working. On this branch's first CI run,
`full test (windows-latest, 24, shard 3/3)` was CANCELLED at exactly 30 minutes;
tests were still passing 0.8s before the cancel, so it is a wall-clock timeout,
not a hang, and a cancelled job reddens `Required tests`.

The cause is not this PR's test file, which costs ~60ms. Shard composition is
unstable: adding ONE file to the unit suite reshuffled 115 of 268 files between
shards, and shard 3 drew a heavier mix. Underneath that is a real pre-existing
defect. tests/ci-test-job-timeout-budget.test.cjs requires every lane's budget to
be >= 1.5x its MEASURED cost -- "a lane that got slower must be re-budgeted, not
excused" -- and its test-full entry recorded 19m from a windows-22 shard. That is
stale. Measured on `next` with none of this PR's changes present: 26m18s (run
32614439702, windows-latest/24 shard 3/3), 23m36s and 23m17s on shard 2/3. So the
lane costs ~26m and the 30-minute cap carried 1.14x headroom, not 1.5x. The gate
had been out of compliance with its own rule; this PR was merely the file
addition that reshuffled shard 3 past the cliff.

Fixed as that file prescribes: measuredMinutes 19 -> 27 with fresh evidence, and
test-full timeout-minutes 30 -> 45. The rule's minimum for 27m is 41; 45 is
deliberately above it because the reshuffle means per-shard worst case moves run
to run, and a budget pinned to the exact minimum would be re-breached by the next
test file anyone adds. Only that one job's timeout changed; test.yml's scope,
matrix and steps are untouched, so #764's saving is unaffected.

Raising that cap let the Windows shard finish (28m45s, inside 45) and uncovered
a real failure the 30-minute cancel had been masking:
`new quick-task branch branches off origin/main (#2916)` died with
`outcome=timed_out exitCode=null`, SIGTERM, at the 15000ms bound.

tests/quick-branching.test.cjs:149 `runStep` runs a `#!/usr/bin/env bash` script
executing MULTIPLE git commands, but was bound to GIT_TIMEOUT_MS (15000) -- the
norm for a SINGLE git plumbing call. tests/helpers/timeouts.cjs already documents
this exact failure and exists to fix it: HOOK_FANOUT_TIMEOUT_MS was created after
PR #3285 recorded "outcome=timed_out exitCode=null at exactly the 15000ms probe
bound while every other lane passed the same commit", and calls that "a bound
sized for the wrong class, not a slow machine". Our failure is that case
verbatim, so both sites move to the class norm rather than to a bigger number.

The same class also failed on `next` itself 21 hours earlier -- run 32608945654,
windows-latest/24 shard 1/3, `plan touching only src/ in a submodule project
keeps worktree isolation ENABLED` -- where tests/worktree-safety.test.cjs:5845
`runGate` fans out to `git config --file .gitmodules` under a hardcoded 30000.
Fixed too, since it is a defect in the tree regardless of which branch surfaced
it.

A survey of the whole tests/ tree found the same class-mismatch at further
bash fan-out sites bound under 60000ms, and the maintainer approved sweeping
them rather than leaving them latent to surface the same way one at a time. 16
fan-out sites across 16 files now use the class norm.

The sweep is class-correctness, not raising numbers until things pass. Sites
were moved ONLY where the bash body demonstrably spawns something (git, node,
npm, a CLI); self-contained shell snippets were left where they are, and are
listed as deliberately unchanged: pure if/printf bodies (copilot-install), pure
array/case builtins (code-review-pipeline-regression:638), a documented
pure-shell gsd_run stub (host-integration), single-process hook calls
(workflow-guard:222/271/302), and a deliberately tight 5000ms fast-check hook
(gsd-write-guard.property). Nothing was lowered. process-seam.test.cjs:513
(literal 300) is untouched on purpose -- it tests timeout BEHAVIOR, so raising
it would destroy what it asserts.

Shared file-level constants were the trap here, and were handled per file rather
than by redefinition: GIT_TIMEOUT_MS has ~15 users in git-base-branch and only 1
is a fan-out; WORKTREE_TIMEOUT_MS has 16 users in worktree.test.cjs and 3 are;
PROBE_TIMEOUT_MS has several in three more files. In each the CALL SITE was
changed and the constant left alone, so no single-plumbing-call site silently
inherited a 60s bound. The one exception is hooks-opt-in.test.cjs, where
HOOK_TIMEOUT_MS has exactly one consumer -- spawnHook, the fan-out itself -- so
redefining it is identical in effect and reads better.

Only two of these sites have actually been observed failing. The rest cite that
shared class and those two run ids rather than inventing evidence of their own.
