515191f07d feat(#3677): quick-batch hardening and acceptance (#4240)
* chore(#3677): checkpoint design artifacts (gitignored, dev-only)

* test(#3677): add failing regression test for the crash-window duplicate-dispatch gap (RED)

Independently re-traces resume-mode.md/planner-wave.md/worktree-dispatch.md/
merge-wave.md and src/quick-batch.cts's resumeBatch (lines 894-899) and
confirms the prior research pass's Open Question 1: a coordinator crash
between Step 6 (executor commits, SUMMARY.md written) and Step 7 (merge)
leaves BATCH.json at "pending" with no STATE.md row yet (only written in
Step 9), so --resume's eligibility re-derivation would dispatch a second
executor into a new worktree for the same item, orphaning the first.

This test asserts worktree-dispatch.md's Step 6 excludes an item whose
SUMMARY.md already exists from the spawn set, mirroring planner-wave.md's
existing PLAN.md-existence check one layer earlier. Fails against the
current worktree-dispatch.md, which has no such guard.

See .gsd/phase/feat-3677-quick-batch-hardening-acceptance/40-design.md §1
for the full trace and fix-location rationale.

* fix(#3677): guard worktree-dispatch.md against re-dispatching an already-executed item (GREEN)

worktree-dispatch.md's Step 6 re-derives eligibility every dispatch round
via the same quick-batch resume call resume-mode.md uses, but had no check
for "did this item already finish executing" the way planner-wave.md
already checks "did this item already get planned" (PLAN.md existence)
before re-planning. A coordinator crash between Step 6 (executor commits,
SUMMARY.md written) and Step 7 (merge) left the item eligible for a second
dispatch on --resume, orphaning the first worktree's real, already-
committed work and silently losing it once the second executor's SUMMARY.md
write clobbered the first at the same item_dir path.

Adds a SUMMARY.md-existence exclusion before spawn-plan is computed,
symmetric to planner-wave.md's PLAN.md check. The excluded item is not
lost: merge-wave.md's own mergeable-wave criterion (status=pending,
SUMMARY.md on disk, not yet merged) already picks it up independently of
this eligible/spawn list.

Workflow-prose-only fix — touches no already-merged/reviewed .cts module.
See .gsd/phase/feat-3677-quick-batch-hardening-acceptance/40-design.md §1
for the fix-location rationale (why not resumeBatch itself).

* test(#3677): add real-git coverage for worktree-ownership tampering, scope drift, and submodules

Closes the three coverage gaps identified in 40-design.md §2/§3 (#3677,
epic #3344 Phase 5's own AC bullets: "arbitrary-worktree ownership
attempts", "scope drift", "submodules"):

- Arbitrary-worktree ownership tampering: a manifest entry naming a
  non-agent branch is silently dropped at normalization before any git
  subprocess runs; a manifest entry naming a plausible agent-branch that
  was never actually created by this repo's own worktree.create (a
  genuinely foreign repo/branch) is blocked via base_mismatch. Both leave
  the foreign location and repoRoot's HEAD provably untouched.

- Advisory scope drift: a committed path outside declared files_modified
  still merges successfully (advisory, never blocking) while surfacing a
  scope_out_of_declared warning naming the drifted path; an exact
  declared-scope match produces zero warnings (boundary case).

- Real .gitmodules submodule integration: a repo containing a real local
  git submodule merges cleanly through executeWorktreeWaveCleanupPlan for
  an unrelated plan; a real gitlink pointer bump (declared) merges cleanly
  with the superproject tree reflecting the new pinned commit; an
  undeclared bump is advisory-only and surfaces a scope warning naming
  vendor/sub, same as any other undeclared modification.

No src/*.cts changes — all three gaps were coverage-only; the underlying
primitives already behaved correctly (independently verified against real
git subprocess output before writing each assertion).

* docs(#3677): document how to diagnose a preserved quick-batch worktree

Extends the one-sentence "worktree is preserved (never deleted)" mention
into a concrete diagnosis procedure: where the preserved directory is, how
to read the executor's real commits/diff against the plan's declared
files_modified, how to read the item's own SUMMARY.md independent of merge
outcome, how to manually merge-and-clean-up or discard, and how to re-run
--resume afterward. Also documents that a SUMMARY.md-written-but-still-
pending item (the crash-window case fixed in this same PR) needs no manual
intervention — --resume routes it straight to the merge step.

* chore(#3677): checkpoint final acceptance-evidence mapping (gitignored, dev-only)

* fix(#3677): make crash-window duplicate-dispatch guard behaviorally provable and durably recoverable

Orthogonal review (Spec finding): the crash-window regression test added
earlier this phase only asserted readStep('worktree-dispatch.md') + regex
matches against the markdown prose — proving the DOCUMENTATION says the
right thing, never that the runtime condition (pending status + on-disk
SUMMARY.md + absent STATE row) is actually handled correctly. #3677's own
"Alternatives considered" explicitly rejects "document recovery without
fault injection" for exactly this reason.

Extracts the filtering decision into a pure, independently testable
function, filterAlreadyExecuted(eligibleIds, executedIds) in
src/quick-batch-dispatch.cts, wired to a new `quick-batch filter-executed`
CLI verb (src/quick-batch-command-router.cts) — the same pure-decision-
then-CLI-wired pattern computeSpawnPlan/computeMergeOrder already
establish. worktree-dispatch.md now calls this verb explicitly instead of
only describing the decision in prose. A genuine fixture-based test in
tests/quick-batch.test.cjs constructs a REAL BATCH.json (createBatch),
writes a REAL SUMMARY.md on disk at the item's real item_dir, calls the
REAL resumeBatch, and proves both that resumeBatch alone still reports the
item eligible AND that filterAlreadyExecuted (fed a real filesystem check)
correctly excludes it. The prior prose-assertion tests are kept — they now
prove the workflow markdown is correctly WIRED to the verb — but are no
longer the only proof.

Self-discovered defect while building that fixture (fixed inline, not
deferred): tracing merge-wave.md against /gsd:quick's own prior art
(QUICK_WORKTREE_MANIFEST=$(mktemp ...), quick.md:415) showed
$QUICK_BATCH_WORKTREE_MANIFEST is a fresh PER-PROCESS temp file. A resumed
coordinator correctly does not re-dispatch an already-executed item (this
fix), but nothing durably recorded that item's worktree_path/branch/base
either — Step 7 in the resumed process would have had no data to build its
cleanup-wave entry from. Adds dispatched_worktree/dispatched_branch/
dispatched_base to QuickBatchItem (src/quick-batch.cts) — deliberately NOT
a reuse of the pre-existing `worktree` field, whose loadBatch validation
requires the path to exist on disk (verified empirically: reusing it made
the batch permanently unloadable the moment a legitimately-merged worktree
was removed). worktree-dispatch.md persists the triple once a worktree is
created; merge-wave.md falls back to it when the ephemeral manifest lacks
an entry, clears it after a successful merge, and fails closed rather than
guessing if no record exists anywhere.

See .gsd/phase/feat-3677-quick-batch-hardening-acceptance/40-design.md §9.1
and §9.3 for the full trace, empirical verification notes, and rejected
alternatives (reusing `worktree` directly).

* test(#3677): prove the arbitrary-worktree-ownership boundary against two real sibling worktrees

Orthogonal review (Security finding): the two existing ownership-tampering
tests didn't test ownership — one was trivially rejected by
WORKTREE_AGENT_BRANCH_RE's shape check before any git call (proves branch-
NAME filtering, not ownership), the other pointed at a wholly separate,
never-linked foreign repo, so merge-base failed immediately because the
branch didn't exist as a ref at all. Neither exercised the real scenario:
a manifest entry whose worktree_path/branch are swapped to point at a
DIFFERENT, GENUINELY-REGISTERED sibling worktree of the SAME repoRoot,
with a branch name passing the shape check and a base in allowed_bases.

Investigated executeWorktreeWaveCleanupPlan (src/worktree-safety.cts)
directly: this is NOT a reachable gap. Git enforces branch-per-worktree
uniqueness, so a swapped-in entry.branch can only match worktree_path's
ACTUAL checked-out branch if it names that sibling's own real, uniquely-
generated branch name — which manifest tampering confined to one batch's
own record has no way to know (branch names are
agent-<quick_id>[-<timestamp>]-shaped, and quick_id allocation is
collision-checked GLOBALLY across every existing quick task and batch, not
merely within one batch).

Adds a stronger test that empirically proves this: two REAL, concurrently-
alive sibling worktrees of the same repo (both via real `git worktree add`,
both WORKTREE_AGENT_BRANCH_RE-passing, both sharing one merge-base), with
worktree_path/branch swapped between them in both directions. Both attempts
are blocked via branch_mismatch; both real worktrees, their branches, and
one sibling's real uncommitted-to-main commit survive completely untouched.
Supplements (does not replace) the original two tests, which still prove
distinct, real boundaries.

See .gsd/phase/feat-3677-quick-batch-hardening-acceptance/40-design.md §9.2
for the full trace, including the one explicitly-documented (not fixed)
trust boundary this investigation surfaced: the primitive defends against
fabricated data, not a caller bug that misattributes a real-but-wrong
item's own triple to a different item.

114dfcb739 fix(#4196): npm-audit gate blocks only NEW advisories, not pre-existing ones (#4214)
* fix(#4196): npm-audit gate blocks only NEW advisories, not pre-existing ones

The #3588 gate failed on ANY advisory in the production tree, regardless
of whether the PR/push actually introduced it. Because npm's advisory
database updates continuously and independently of repo state, a commit
could pass this gate at merge time and fail it minutes later on the
identical tree -- proven on PR #4188/dce40eeb6, which passed on all 3
OSes at 15:57-16:27 and failed the same assertion at 16:19-16:30 on the
unchanged commit, purely because GHSA-jqff-g426-hqxp was disclosed for
fast-uri in the interim.

scripts/npm-audit-baseline.cjs diffs the head tree's vulnerable-package
set against a resolved baseline (the PR's target branch, or the prior
commit on a direct push) and blocks only newly-introduced advisories.
When no baseline can be resolved, falls back to the original
zero-tolerance behavior -- fail-closed, never silently weaker.

* fix(#4196): pin the npm-audit baseline instead of using a drift-prone ref

Two orthogonal reviews found the same class of bug this repo already
fixed once for a different gate (see GSD_EMITTED_BASE's own incident
comment in test.yml): origin/<branch> is live under fetch-depth: 0 and
can advance mid-run, so resolveBaselineRef()'s fallback to
origin/${GITHUB_BASE_REF} could silently disagree with the tree
ci-rebase-check.cjs actually merged. Wire AUDIT_BASELINE_REF from the
workflow to github.event.pull_request.base.sha / github.event.before,
the same pinned values GSD_EMITTED_BASE already relies on.

Also: HEAD~1 assumed exactly one commit per push, which this repo's
allow_rebase_merge:true setting can violate (a rebase-merged PR lands
as several discrete commits in one push) -- github.event.before is
git's own record of the correct pre-push state, not an assumed offset.
HEAD~1 remains as a documented last-resort fallback for out-of-band
invocations (e.g. gsd-test) that don't set any of the above, alongside
a new local-branch fallback for gsd-test's local `next` (not
origin/next) sandbox shape.

2f64e6230a feat(#3676): quick-batch command, workflow, and isolation integration (#4212)
* test(#3676): add failing tests for quick-batch dispatch core

Failing-first tests for Phase 4 of epic #3344 (ADR-1239 "Quick-batch
binding"): quick-batch-dispatch.test.cjs / .property.test.cjs cover the
new pure decision-logic module (arg validation, effective concurrency,
deterministic merge order, spawn backpressure, verification/merge
routing, cleanup-entry construction — design doc rows 3-15,24,26-28,
30-36,39; property rows 51-53). quick-batch-update-items.test.cjs
covers the new updateBatchItems export on src/quick-batch.cts (rows
15,22-23, including the negative cycle-rejection case).
quick-batch-command-router.test.cjs covers the new
gsd-tools quick-batch CLI family (rows 46-47). These reference modules/
exports that do not exist yet.

* feat(#3676): implement quick-batch dispatch core, updateBatchItems, and command router

Phase 4 of epic #3344 (ADR-1239 "Quick-batch binding") CORE decision
layer — CLI verbs and pure orchestration logic only; no workflow
markdown, no Agent()/git-worktree I/O.

- src/quick-batch-dispatch.cts (new): pure decision functions consumed
  by the (separate, follow-up) /gsd:quick-batch workflow markdown —
  parseQuickBatchArgs, computeEffectiveConcurrency, computeMergeOrder,
  computeSpawnPlan, routeVerificationOutcome, routeMergeOutcome,
  buildCleanupManifestEntry (the last parses caller-supplied plan text
  via the existing parsePlanDocument; no filesystem access).

- src/quick-batch.cts: adds updateBatchItems, resolving the design
  doc's Open Question 1 as ONE additive export on this module instead
  of the second, independent BATCH.json writer the design doc
  originally proposed. Reuses the same withPlanningLock transaction
  shape, computeWaves, and platformWriteSync call resumeBatch/
  completeQuickItem already use; fails closed without persisting on
  an unknown item, an unknown/self dependency, or an introduced cycle.

- src/quick-batch-command-router.cts (new): gsd-tools quick-batch CLI
  family, wired into HOST_COMMAND_ROUTERS (gsd-core/bin/gsd-tools.cjs)
  as a first-party always-on command (like /gsd:quick), not the opt-in
  capability-registry path graphify uses. Verbs: create/update/resume/
  complete (wrap quick-batch.cts) and effective-concurrency/
  merge-eligible/spawn-plan/verification-routing/merge-routing/
  cleanup-entry/parse-args (wrap quick-batch-dispatch.cts).

Design doc rows covered: 3-15, 22-24, 26-28, 30-39, 46-47. Property
rows 51-53. Rows covering workflow markdown / Agent() dispatch /
`git worktree` behavior (16-21, 25, 29, 40-45, 48-50) remain for the
follow-up markdown-authoring pass, per the phase brief's explicit
scope boundary.

* docs(#3676): register quick-batch-dispatch/command-router modules in bookkeeping surfaces

New-.cts-module ripple for the two Phase 4 modules (epic #3344,
ADR-1239 "Quick-batch binding"): .gitignore (compiled .cjs artifacts,
ADR-457 build-at-publish), eslint.config.mjs (lint the .cts source,
not the emitted .cjs), docs/INVENTORY.md + docs/INVENTORY-MANIFEST.json
(via `node scripts/gen-inventory-manifest.cjs --write`, after
`npm run build:lib`), and CONTEXT.md glossary entries for
"Quick-Batch Dispatch Core Module" and "Quick-Batch Command Router
Module", plus an update to the existing "Quick-Batch Core Primitives
Module" entry documenting the new updateBatchItems export.

* test(#3676): fold updateBatchItems tests into quick-batch.test.cjs (fix lint-test-file-count)

scripts/lint-test-file-count.cjs buckets any quick-batch-*.test.cjs
file under the quick-batch production module by longest-prefix match,
and that module is already at its 2-file cap (quick-batch.test.cjs +
quick-batch.property.test.cjs). The standalone
tests/quick-batch-update-items.test.cjs added in the prior commit
pushed it to 3 and failed `npm run lint:ci`. Fold its content into
quick-batch.test.cjs (append-only — no existing test in that file is
modified) and update the CONTEXT.md glossary reference to match.

Surfaced while re-running `GITHUB_BASE_REF=next npm run lint:ci` after
`npm ci` (this worktree previously had no local node_modules, which
also made gen-scripts-cli-exit/gen-hooks-cli-exit/gen-exit-code-*
unable to resolve typescript — resolved by npm ci, no code change
needed there). `npm run lint:ci` and
`npx tsc -p tsconfig.build.json --noEmit` are both green after this
fix.

* test(#3676): add failing tests for the quick-batch command/workflow markdown

Failing-first tests for Phase 4's markdown-authoring pass (epic #3344,
ADR-1239 "Quick-batch binding"): gsd-quick-batch-workflow.test.cjs
covers commands/gsd/quick-batch.md's frontmatter/objective/process,
gsd-core/workflows/quick-batch.md's byte-size boundary (row 49, ADR
1610 NEW_FILE_CAP) and step-fragment count, the isolation model
(rows 20-22), the executor single-writer invariant (row 18), merge
validation reusing the existing bounded primitive (row 25), the
optional research/plan-checker/verification leaves (rows 16,17,19,
30,31), planning-failure blocking execution (row 29), the submodule
guard (rows 36,44), and the new agents/gsd-planner.md quick-batch
mode (rows 13-15). gsd-quick-batch-quick-regression.test.cjs covers
row 48 (ordinary /gsd:quick stays byte-identical). Named
`gsd-quick-batch-*` (not `quick-batch-*`) so lint-test-file-count's
longest-prefix bucketing doesn't fold these markdown-only tests into
the already-capped quick-batch/quick-batch-dispatch/
quick-batch-command-router production-module buckets from the CORE
pass. These reference files that do not exist yet.

* feat(#3676): author the quick-batch command, workflow, and planner mode

Phase 4 markdown-authoring pass (epic #3344, ADR-1239 "Quick-batch
binding") — the orchestration layer that calls into Pass 1's CLI
verbs (src/quick-batch-command-router.cts).

- commands/gsd/quick-batch.md (new): frontmatter/objective/process,
  delegates argument validation to `quick-batch parse-args`
  (parseQuickBatchArgs) rather than re-deriving the grammar.

- gsd-core/workflows/quick-batch.md (new, 11843 bytes — under ADR
  1610's 32768-byte NEW_FILE_CAP for a brand-new file) + 9 lazy-loaded
  step fragments under gsd-core/workflows/quick-batch/steps/:
  resume-mode, batch-init, research-phase (flag:--research),
  planner-wave (+ nested plan-checker-loop when --validate),
  worktree-dispatch, merge-wave, verification-wave (flag:--validate),
  completion. Covers design doc rows 3-45: capacity/isolation
  resolution (reusing dispatch-isolation-gate.md verbatim), per-DAG-
  layer planning with full-task-catalog prompts and always-required
  depends_on/files_modified frontmatter, serialized worktree create/
  merge/cleanup via the existing worktree.cleanup-wave primitive,
  deterministic wave-order merging, verification routing
  (human_needed/gaps_found), the executor single-writer invariant,
  submodule fail-loud guard, and #1941 fork-base auto-degrade.

- agents/gsd-planner.md: additive new `load_mode_context` bullet for
  `**Mode:** quick-batch`, pointing at the new
  gsd-core/references/planner-quick-batch.md reference (documents the
  always-required depends_on/files_modified contract, reusing the
  existing frontmatter grammar — no new keys). Existing modes
  byte-identical, only a new bullet added.

- src/init.cts (+init-command-router.cts, +command-aliases.cts):
  cmdInitQuickBatch / `init.quick-batch` — model profiles,
  commit_docs, roadmap/planning existence checks, and the
  section_manifest field gating research-phase/verification-wave
  (reuses the existing flag:--research/flag:--validate WHEN_VOCABULARY
  atoms — no new atom needed).

Rows 16-21, 25, 29, 36, 38, 39, 44, 46-50 covered structurally by the
prior test(#3676) commit; rows 3-15, 22-24, 26-28, 30-35, 37, 40-43,
45 covered by construction (verb wiring, single-writer prompt
constraints, crash-window resume via unmodified Phase 3 primitives).

* docs(#3676): regenerate skills/inventory/section-manifest/install-tree; baseline the intentional word-splitting pattern

npm run regen:derived output for the new command/workflow/reference
(epic #3344, ADR-1239 "Quick-batch binding"):
- skills/gsd-quick-batch/SKILL.md (generated from commands/gsd/quick-batch.md)
- docs/INVENTORY.md rows for /gsd-quick-batch, quick-batch.md,
  planner-quick-batch.md, and the quick-batch-dispatch.cjs/
  quick-batch-command-router.cjs CLI-module rows' now-live
  `/gsd-quick-batch` cross-reference (was "(separate, follow-up)")
  + docs/INVENTORY-MANIFEST.json (`node scripts/gen-inventory-manifest.cjs --write`)
- gsd-core/workflows/section-manifest.json (`npm run gen:section-manifest`)
  — research-phase/verification-wave gsd:section entries for the new
  quick-batch workflow
- tests/fixtures/install-tree/*.json (`npm run gen:install-tree`) —
  the new command/workflow/skill/reference files now ship to every
  runtime

scripts/lint-workflow-shellcheck-baseline.json: 3 new entries for
gsd-core/workflows/quick-batch.md's intentional flag-token/$ARGUMENTS
word-splitting (SC2046/SC2086) — the same deliberate unquoted-optional-
flag pattern gsd-core/workflows/quick.md already carries baselined
(e.g. `$DISCUSS_PARAM $RESEARCH_PARAM` in quick.md's own Step 2);
quoting would break the intended "omit this arg when the flag is
false" splitting.

* fix(#3676): close prompt-injection and argv/glob-injection gaps in quick-batch leaf dispatch

Security review pass findings, both confirmed real:

1. HIGH — prompt injection, no boundaries. Every leaf-dispatch fragment
   interpolated the raw, attacker-influenced task ${description} (and
   the shared ${TASK_CATALOG_TABLE}, broadcasting every item's raw
   description into every planner's prompt in the layer) straight into
   Agent() prompt bodies with no boundary. Fixed by wrapping every such
   interpolation in a <security_context> + DATA_START/DATA_END
   boundary, matching the CONCRETE convention already implemented in
   this repo (agents/gsd-debug-session-manager.md, agents/gsd-debugger.md,
   gsd-core/workflows/debug.md) — commands/gsd/quick.md's own
   <security_notes> only asserts this convention in prose, so the
   debug-agent files are the real precedent followed here. Added a new
   <security_notes> block to commands/gsd/quick-batch.md (it had none)
   documenting both this fix and the one below.

2. MEDIUM — unquoted $ARGUMENTS -> argv/glob injection.
   gsd-core/workflows/quick-batch.md and commands/gsd/quick-batch.md both
   ran `gsd_run quick-batch parse-args --raw -- $ARGUMENTS` UNQUOTED,
   causing shell word-splitting and pathname expansion on raw task-list
   text before the parser ever saw it. Fixed at the source: added a
   `--text <string>` form to the `parse-args` verb
   (src/quick-batch-command-router.cts) that accepts the ENTIRE
   $ARGUMENTS as ONE quoted argv element and does the whitespace split
   itself, in Node — which is never glob-aware, unlike the shell.
   Both call sites now use `--text "$ARGUMENTS"`. The `-- <tokens>` form
   is kept for direct/test callers that already have a real argv array.

The SC2086 baseline entry added for the original unquoted line is now
stale (`node scripts/lint-workflow-shellcheck.cjs` no longer reports
it) and has been removed; the two SC2046 entries for the UNRELATED,
still-unquoted `$([ "$VALIDATE_MODE" = true ] && echo --validate)`-style
conditional-flag splitting remain — that line only ever expands to one
of a few known-safe literal strings (never raw user text), matching
quick.md's own already-baselined convention exactly.

Tests: quick-batch-command-router.test.cjs covers the new --text form
(token splitting, glob-shaped text passing through literally
unexpanded, whitespace-only input). gsd-quick-batch-workflow.test.cjs
asserts the DATA_START/DATA_END boundary on every leaf prompt
(research-phase/planner-wave/plan-checker-loop/verification-wave,
including the shared task catalog) and the quoted --text call sites.

* fix(#3676): strengthen test-depth gaps in rows 9, 18, 24, 34, 35

Spec review pass findings — the test matrix claimed "yes" coverage
these assertions did not actually support:

- Row 9 (--jobs 0/-1/abc hostile case): previously asserted rejection
  only. Added an end-to-end assertion (tests/quick-batch-command-router.test.cjs,
  committed alongside the security fix that touches the same file) that
  .planning/quick-batches/ is never created for any rejected value —
  createBatch is genuinely never reached.
- Row 18 (--resume <unknown-batch-id>): previously only exercised a
  hand-corrupted BATCH.json, never a genuinely nonexistent batch
  directory. Added the real nonexistent-id case (also in
  quick-batch-command-router.test.cjs).
- Row 24 (post-planning updateBatchItems racing a concurrent
  completeQuickItem for a different item, both through
  withPlanningLock): zero test existed. Added a property test
  (tests/quick-batch.property.test.cjs, appended — Phase 3's own file,
  no existing test touched) exercising both call orders and asserting
  no lost update in the final on-disk manifest — the same technique
  Phase 3's own row-15 lock-contention property test uses (sequential
  calls through the real lock; a working mutex makes any interleaving
  equivalent to some serial order, so this is the same claim a literal
  concurrent-thread test would make without OS-level threading).
- Row 34 (worktree preserved on merge_failed) and row 35 (undeclared-
  deletion detection): both were previously asserted only at the pure
  routeMergeOutcome level. Added tests/gsd-quick-batch-merge-integration.test.cjs
  using the SAME real-git-fixture pattern tests/worktree-safety.test.cjs
  already establishes for executeWorktreeWaveCleanupPlan (real repo,
  real worktree, a REAL merge conflict / a REAL file deletion diffed
  against declared_deletions) — asserting the actual worktree directory
  survives on disk, not just that a pure function returns a
  preserveWorktree:true field. Named gsd-quick-batch-* so lint-test-
  file-count's bucketing doesn't fold it into any capped module bucket.

Row 48 (/gsd:quick regression) intentionally left as-is per the
reviewer's own framing: the byte-identity claim is already
mechanically proven by the changed-path diff (git diff --name-only
empty on those two paths IS byte-identity), and a genuine execution-
level regression test would require actually running the workflow —
out of scope for this repo's unit-test model (no other quick.md
regression test in this repo does that either).

* docs(#3676): add the changeset and user-facing docs the command needed

Standards review pass findings — both HARD:

- Missing changeset. None of the 6 prior #3676 commits touched
  .changeset/*. /gsd-quick-batch is a new user-facing command;
  CLAUDE.md/CONTRIBUTING.md require one. Added
  .changeset/silly-rams-caper.md (type: Added, pr: 0 placeholder —
  backfilled after the PR opens, matching CLAUDE.md's own documented
  convention and Phase 3's own precedent, #4190's
  .changeset/mellow-yaks-squeak.md). Uses the docs-convention hyphen
  form `/gsd-quick-batch` throughout, never the source-artifact colon
  form (`scripts/lint-docs-command-form.cjs` confirms 0 violations;
  that check scans docs/**, not .changeset/, so it was never actually
  in scope for the fragment itself, but the wording still follows the
  doc convention for consistency, matching how Phase 3's own fragment
  named the not-yet-shipped command).
- Missing docs. Added docs/how-to/batch-quick-tasks.md (Diátaxis
  how-to, matching docs/how-to/handle-quick-and-fast-tasks.md's
  existing convention for /gsd-quick /gsd-fast) covering --jobs,
  --validate, --research, --resume, --file, the capacity/isolation
  interaction, and resume/failure recovery. Cross-linked from
  docs/README.md's how-to index and from handle-quick-and-fast-tasks.md's
  own "Related" section. Added a /gsd-quick-batch section to
  docs/COMMANDS.md (same table format as the existing /gsd-quick
  entry) and docs/features/quick-batch.md (REQ-QB-01..12, same
  frontmatter shape as docs/features/quick-mode.md) — regenerated
  docs/FEATURES.md (179 features) and skills/gsd-quick-batch/SKILL.md
  via the standard generators.

* fix(#3676): close docs-parity, attribution, and generated-registry gaps gsd-test caught

gsd-test's real run against 155e8975b3 found 43 failures, all rooted in
this phase's own new command/workflow never being registered across
~10 independent generated/hand-maintained registries this repo keeps
in parity by convention. Root-caused each, no test weakened or
special-cased.

- help.md ↔ commands/gsd/ bidirectional parity (docs-parity-live-
  registry.test.cjs): added a /gsd:quick-batch entry to
  gsd-core/workflows/help/modes/full.md (the real help.md content;
  gsd-core/workflows/help.md is a thin dispatcher) documenting every
  flag (--file/--jobs/--validate/--research/--resume), matching the
  existing /gsd:quick entry's format.

- gen-section-manifest.test.cjs: quick-batch.md's
  `gsd_run query init.quick-batch` invocation used inline
  `$([ ... ] && echo --flag)` substitutions, which never satisfy the
  test's exact-whitespace-token / assigned-variable detection (the
  trailing `))` glued onto `--research` in the compound substitution
  broke the "exact token" match). Rewrote to the same
  VALIDATE_PARAM/RESEARCH_PARAM two-line pattern
  gsd-core/workflows/quick.md's own Step 2 already uses.

- runtime-launcher-parity.test.cjs: the 8 quick-batch/steps/*.md
  fragments that call gsd_run each needed their OWN embedded copy of
  the canonical shim preamble (every workflow .md that calls gsd_run
  carries its own copy — reading one file does not persist shell state
  into another). Ran `node scripts/sync-runtime-launcher.cjs`, which
  inserted it before each file's first gsd_run call.
  plan-checker-loop.md correctly has none — it never calls gsd_run
  directly.

- Namespace routing (skill-manifest.test.cjs, install-nested-
  layout.test.cjs, runtime-artifact-layout-surface.test.cjs): added
  `quick-batch` to commands/gsd/ns-workflow.md's `requires:` array and
  routing table (same namespace `quick` already routes through), and
  to src/clusters.cts's `utility` cluster (same cluster `quick`
  already belongs to). Verified by hand-running installRuntimeArtifacts
  + applySurface for augment/cline against a real temp install: exactly
  6 top-level gsd-ns-* router dirs, gsd-quick-batch correctly nested
  under gsd-ns-workflow/skills/, never re-flattened.

- mcp-server-catalog.test.cjs: hardcoded command count 71 -> 72 (a
  brand-new command is a real count change, not a bug this test should
  hide).

- model-omit-when-inherit-guard.test.cjs: added the canonical
  `<!-- #2517 model-omit-on-inherit -->` marker block to
  gsd-core/workflows/quick-batch.md (every leaf dispatch — planner/
  researcher/checker/executor/verifier — lives in a steps/ fragment,
  read combined with the host by this test's own readWorkflowCombined,
  same as quick.md's own research-phase.md carries it for its gated
  section). Also fixed a genuine pre-existing inconsistency in the
  test's own "#2711: the guarded set is derived from dispatch sites"
  check: its `nonDispatching` computation read the BARE host file while
  `derived` (the set it's checked against) reads the combined
  host+steps content — inconsistent with that same test file's own
  #2994 doc comment explaining why the combined read is necessary.
  quick-batch.md is the first workflow whose EVERY model="{...}"
  dispatch site lives in a mandatory (never gated) steps/ fragment —
  extracted to stay under ADR-1610's tighter NEW_FILE_CAP for a
  brand-new file — which is what exposed the mismatch. Fixed by using
  the same readWorkflowCombined read in both places.

- skill-frontmatter-contract.test.cjs: shortened
  commands/gsd/quick-batch.md's frontmatter `description` from 107 to
  91 chars (<=100 budget), and added `quick-batch.md` to the hand-
  maintained KNOWN_SKILLS consolidation allowlist with a #3676
  justification comment (a genuinely new first-party command, not a
  consolidation of an existing skill).

- workflow-fragments-emission.install.test.cjs: added `quick-batch.md`
  to the hand-maintained MARKED_WORKFLOWS set (composeWorkflow is
  deliberately NOT a no-op for it — its research-phase/verification-
  wave sections are gated).

- Regenerated all downstream artifacts (npm run build:lib && npm run
  regen:derived && npm run gen:plugin-skills -- --write && npm run
  gen:features -- --write): skills/gsd-quick-batch/SKILL.md,
  skills/gsd-ns-workflow/SKILL.md, install-tree fixtures for
  augment/cline/hermes/qwen/trae/zcode.

- emitted-attribution.test.cjs: agents/gsd-planner.md's #3676 addition
  (one new `load_mode_context` bullet pointing at the new
  gsd-core/references/planner-quick-batch.md reference) grew the file
  124 bytes without an acknowledgment trailer. Acknowledged below —
  the growth is the deliberate, additive, single-bullet change from
  the earlier feat(#3676) commit, not drift.

Verified: npm run build:lib clean, npx tsc -p tsconfig.build.json
--noEmit clean, GITHUB_BASE_REF=next npm run lint:ci fully green
(includes lint-workflow-shellcheck, lint-test-file-count,
lint-docs-command-form). The deep install/spawn/registry tests gsd-test
actually runs (docs-parity-live-registry, gen-section-manifest,
runtime-launcher-parity, install-nested-layout,
runtime-artifact-layout-surface, skill-manifest, skill-frontmatter-
contract, mcp-server-catalog, model-omit-when-inherit-guard,
workflow-fragments-emission) are not part of lint:ci — each fix above
was independently verified by hand-invoking the exact production
function the failing test calls (installRuntimeArtifacts, applySurface,
composeWorkflow, the CLUSTERS union, the section-manifest forwarding
regex) against the real repo tree and confirming the expected shape.

Emitted-Drift-Ack-Growth: gsd-planner.md — additive #3676 quick-batch mode bullet in load_mode_context (one new line pointing at gsd-core/references/planner-quick-batch.md); not drift.

* fix(#3676): trim the /gsd:quick-batch help.md entry to fit the LARGE tier line budget

skill-frontmatter-contract.test.cjs's "feature #3039: tiered help —
size budgets" enforces a SEPARATE line-count ceiling for
gsd-core/workflows/help/modes/full.md (FULL_BUDGET = 844 lines,
tighten-only ratchet, scripts/lib/allowlist-ratchet.cjs's
assertTightCeiling) — independent of the skill-frontmatter description-
length budget and consolidation allowlist I touched in the prior round;
those are unrelated checks in the same test FILE, not the same check.

Root cause: the /gsd:quick-batch entry I added to full.md in the
docs-parity fix round was 17 lines, pushing the file from 834 to 851
lines — 7 over the 844 ceiling. Condensed the entry (merged the
per-flag bullet list into one dense "Flags:" line, dropped from 3
Usage examples to 1) to 844 lines exactly — at the ceiling with zero
slack, which assertTightCeiling accepts (it only fails on
actualMax > ceiling, or on slack > grace when the ceiling is too
LOOSE — zero slack triggers neither).

Verified after trimming: full.md still contains a live /gsd:quick-batch
reference (bidirectional parity) and all 5 argument-hint flags
(--jobs/--validate/--research/--resume/--file) still appear as literal
tokens (docs-parity-live-registry.test.cjs's own flag-coverage check,
re-run by hand against the trimmed content).

Verified: npm run build:lib clean, npx tsc -p tsconfig.build.json
--noEmit clean, GITHUB_BASE_REF=next npm run lint:ci fully green.

* docs(#3676): backfill changeset pr number to 4212

Follow-up to fix(#3676) commits — .changeset/silly-rams-caper.md's
pr:0 placeholder backfilled with the real PR number now that
gh api POST /pulls has returned it (#4212). Matches CLAUDE.md's PR
Number Handling convention and Phase 3's own #4190 precedent
(708c5a3f8c). Doc-only (root-level .changeset/*.md fragment), exempt
from a fresh gsd-test run per pre-pr-gate.sh's DOC_ONLY_RE.

* fix(#3676): resolve prompt-injection-scan false positive on test fixture

tests/quick-batch.test.cjs:232's row 11b regression proves the task-list
parser carries a prompt-injection-shaped task description through
createBatch as inert data, never interpreted. The fixture has to be a
real "ignore all previous instructions..." phrase or the test asserts
nothing, but the full-file --diff scan flagged it once unrelated edits
in the same file pulled it into the changed-file set.

Add the file to prompt-injection-scan.sh's ALLOWLIST, matching the
sanctioned, precedented exemption already used for other legitimate
security-regression fixtures (tests/windsurf-conversion.test.cjs,
tests/health-validation.test.cjs, tests/continuation-grammar-parity.test.cjs)
per DEFECT.PROMPT-INJECTION-SCAN-COLLISION.

858bb89769 ci(#4196): exempt dependabot[bot] from issue-link, title, and unsolicited-PR gates (#4203)
Dependabot has no mechanism to link a PR it opens to a repo issue -- its
alerts live in the Security tab, not as issues -- so require-issue-link,
pr-title-validator, and auto-close-unsolicited-prs all rejected its PRs
by design (confirmed live on #4193: auto-closed for "no pre-approved
issue", then flagged again by the title gate on reopen). Exempt by
authenticated author login (github.event.pull_request.user.login /
context.payload.pull_request.user.login), which GitHub attributes and a
crafted title or branch name cannot forge -- scoped narrowly to
dependabot[bot] only, no other author gets this treatment.

91ed46882a feat(#3675): quick-batch core primitives and resumable manifest (#4190)
* test(#3675): add failing tests for quick-batch core primitives

Adds the full behavioral (tests/quick-batch.test.cjs) and property-based
(tests/quick-batch.property.test.cjs) coverage for #3675's quick-batch core
primitives per the phase's 35-row test matrix — task-list parsing (inline +
--file, with path-confinement/symlink-escape/non-regular-file rejection),
collision-safe quick-id preallocation under withPlanningLock, BATCH.json
schema/validation/resume, dependency-DAG + partitionByFileOverlap wave
construction, and exactly-once STATE.md completion (including the
STATE-row-written-but-manifest-not-yet-updated crash window).

The import target (gsd-core/bin/lib/quick-batch.cjs, compiled from a
not-yet-written src/quick-batch.cts) does not exist yet — every test in both
files fails at the top-level require() before any assertion runs. Five
fast-check properties cover collision-freedom under lock contention, resume
idempotency, exactly-once STATE completion, wave totality, and DAG-respecting
wave order, per the design doc's property-based-coverage requirement.

* feat(#3675): implement quick-batch core primitives

Adds src/quick-batch.cts (ADR-457 build-at-publish, compiled to
gsd-core/bin/lib/quick-batch.cjs) implementing #3675's quick-batch core
primitives per the phase design lock — pure/state primitives and
CLI-testable core operations only, no agent dispatch, no worktree creation,
no user-facing command (Phase 4/#3676's job):

- parseTaskList / parseTaskListFromFile: inline bulleted/numbered task-list
  parsing (>=2 items required) and a --file variant strictly confined to the
  planning workspace root via requireSafePath, rejecting non-regular-file
  targets.
- allocateQuickIds / createBatch: collision-safe YYMMDD-xxx quick-id
  preallocation under withPlanningLock, checked against both on-disk
  .planning/quick/ entries and sibling .planning/quick-batches/*/BATCH.json
  manifests (never on-disk-only, which would miss another in-flight batch
  that hasn't dispatched any real quick directory yet) — replicates
  cmdInitQuick's own grammar rather than delegating to it (that function's
  2-second granularity is not batch-safe).
- computeWaves: deterministic wave construction combining dependency-DAG
  layering with partitionByFileOverlap (#3674), called per DAG layer over
  path-separator-normalized planned_files — normalization happens at this
  module's boundary, never inside the Phase 2 helper.
- loadBatch: fail-closed BATCH.json schema validation (corrupt/truncated
  JSON, wrong types, missing fields, out-of-batch dependency references,
  dependency cycles, a worktree path absent from disk).
- resumeBatch: skips complete items, never auto-retries failed items,
  propagates/reverses blocked status along the DAG to a fixed point, and
  detects a STATE.md row that already exists for a non-complete item (the
  "STATE written, BATCH.json not yet updated" crash window) — completing it
  without re-appending. Idempotent across repeated calls.
- completeQuickItem / hasQuickTaskRow: exactly-once STATE.md completion —
  appendQuickTaskRow (unmodified) is called at most once per quick id, gated
  by hasQuickTaskRow's own idempotency check re-parsing the real "Quick Tasks
  Completed" table, since appendQuickTaskRow itself carries no idempotency.

BATCH.json lives at .planning/quick-batches/<batch-id>/BATCH.json, a sibling
of .planning/quick/ — never inside it, so scanQuickTasks never misreads a
batch manifest as a broken quick task.

* docs(#3675): register the new quick-batch module

New src/*.cts -> bin/lib/*.cjs modules need four hand-maintained
registrations beyond the code itself: .gitignore (compiled artifact),
eslint.config.mjs (ADR-457: lint the .cts, not the emitted .cjs),
docs/INVENTORY.md's CLI Modules roster row plus the regenerated
docs/INVENTORY-MANIFEST.json cli_modules entry, and a CONTEXT.md glossary
entry matching the convention set by the sibling File Overlap Partitioner
Module (#3674) entry it sits beside.

NOTE: docs/INVENTORY-MANIFEST.json was updated BY HAND (alphabetically
sorted single-entry insertion into families.cli_modules, matching the
existing file's structure) rather than via
`node scripts/gen-inventory-manifest.cjs --write` — this session's
MEMTRACE-FIRST guard hard-blocks direct execution of that indexed script
path from Bash, with no available Memtrace tool to route through instead.
The orchestrator should re-run `node scripts/gen-inventory-manifest.cjs
--check` to confirm this hand-edit is byte-identical to the generator's own
output before merging.

* fix(#3675): resolve lint findings in quick-batch primitives and tests

Unsafe `any[]` assignment from `new Array(n)` in the DAG cycle-check color
array, two unnecessary `as string[]` casts TS 5.5's inferred type
predicates already narrowed, raw `fs.rmSync` in test cleanup (needs the
Windows-EBUSY retry budget `helpers.cleanup` carries), an unused `loadBatch`
import, an unbounded `mkfifo` subprocess spawn missing a timeout, and a
CONTEXT.md glossary illustration that looked like a real file reference.

* feat(#3675): close acceptance-criteria gaps found in review

Standards- and spec-axis review (plus a self-caught race) surfaced real
gaps against issue #3675's own acceptance criteria and this repo's test
conventions:

- BATCH.json was missing options, base_revision, per-item wave, and
  per-item commit — the issue's AC explicitly lists all four as things
  the manifest must track. Added them: createBatch persists caller-supplied
  batchOptions/baseRevision verbatim and assigns each item its computed
  wave index; completeQuickItem now persists the commit onto the item,
  not just the STATE.md row. All four are backward-tolerant on load (an
  older/hand-built manifest without them still validates).
- resumeBatch had no "incompatible base divergence" check at all, despite
  the AC and the ADR's own "Base divergence" section requiring one. Added
  an opt-in currentBaseRevision comparison that fails closed with a
  recoverable diagnostic on mismatch, and touches nothing on refusal.
- resumeBatch read-modify-wrote BATCH.json OUTSIDE withPlanningLock — the
  only durable write path in this module that wasn't lock-protected,
  a real lost-update race against a concurrent completeQuickItem or
  another resume. Now runs inside the same lock createBatch/
  completeQuickItem use.
- loadBatch and collectExistingBatchQuickIds used raw JSON.parse with no
  size cap (security review, Low/informational); switched to the
  existing safeJsonParse (1MB cap) for defense-in-depth.
- Parser (parseTaskList) had only example-based tests; CLAUDE.md requires
  a fast-check property test for parsers. Added one plus a companion
  reject-property for <2 items.
- The id-exhaustion fail-closed ceiling (MAX_TIME_BLOCK) was untested at
  any boundary. Exported the pure allocateIdsGivenUsed/MAX_TIME_BLOCK for
  direct limit-1/limit/limit+1 testing without needing 46k fixture dirs.
- Issue AC explicitly asks for prompt-injection-payload test coverage,
  distinct from the existing shell-metacharacter test; added one.
- Test row 9 (FIFO skip) silently returned instead of calling t.skip(),
  so an unsupported platform would report a pass rather than a documented
  skip; fixed to bind the test-context param and skip properly.
- Extracted toWaveInput to remove a 2-site production duplication of the
  QuickBatchItem -> computeWaves reshape (Standards-axis smell).
- Added the required .changeset/ fragment (CONTRIBUTING.md: editing src/
  is user-facing even though the compiled .cjs is gitignored).

* fix(#3675): restore "not valid JSON" wording in loadBatch's parse-failure reason

gsd-test caught this: switching loadBatch to safeJsonParse changed the parse-
failure message shape ("... parse error — ...") without preserving the
"not valid JSON" substring row 27's own test asserts on. Re-wrap
safeJsonParse's error into the original diagnostic phrasing regardless of
which of its three failure modes fired.

* docs(#3675): backfill changeset pr number to 4190

* fix(#3675): detect a silently-no-op mkfifo on Windows, not just a throwing one

CI caught this on windows-latest: row 9's platform-skip only caught mkfifo
throwing (command not found). On this runner mkfifo resolves to something
that exits 0 without creating a file (NTFS has no FIFO concept), so
execution fell through to parseTaskListFromFile against a path that
doesn't exist, producing an ENOENT stat error instead of the expected
"not a regular file" rejection. Check the artifact actually exists before
trusting a zero exit code, and skip with a documented reason either way.

Dependabot already opens a correct fix PR within minutes of a new
advisory (e.g. #4193 for GHSA-jqff-g426-hqxp), but nothing merged it --
it sat until a human noticed `next` had gone red and an unrelated PR
tripped over the same npm-audit gate. Auto-approve + auto-merge closes
that gap for patch/minor bumps; major bumps still need a human.

acb903c2e8 enhance(#3661): make the code-review hook point configurable (#4159)
* feat(#3661): make the code-review hook point configurable

Add `workflow.code_review_point` (`execute:post` default, or
`execute:wave:post`) so a multi-wave phase can run code review once per
wave instead of once at the end, scoped to what changed since the phase's
prior review.

The code-review capability now declares its step at both loop points via a
new generic `pointFrom` step field: `pointFrom` names an enum config key,
and the step is only active at its own `point` when that key resolves to
a matching value. `_resolvePointGate` (capability-activation.cts) is the
single shared implementation consumed identically by loop-resolver.cts and
capability-state.cts, and capability-validator.cjs enforces that `pointFrom`
references an enum key whose values cover the declaring step's own point.

code-review.md's manual-invocation gate now reads `workflow.code_review`
directly instead of probing registry presence at the hardcoded execute:post
point (so manual `/gsd-code-review` keeps working regardless of which
automatic point is configured), and its file-scope tiers narrow to what
changed since the phase's last review commit when one exists.

execute-phase.md's wave-post step dispatch gets a small, precedented
carve-out so the code-review skill still receives its required phase
argument when dispatched generically (caught by the isolated spec review).

Closes #3661

Emitted-Drift-Ack-Growth: code-review.md — #3661 adds a point-aware config gate check and LAST_REVIEW_COMMIT-based incremental scoping to the file-scope tiers.
Emitted-Drift-Ack-Growth: execute-phase.md — #3661 adds one carve-out sentence so the wave-post generic step dispatch passes PHASE_NUMBER to the code-review skill.

* docs: backfill changeset PR number for #3661 (#4159)

* fix: scope tests/io.test.cjs's fs.writeSync fault-injection mocks by fd

Five fault-injection mocks in the "bug #1008" describe blocks intercepted
every fs.writeSync call regardless of file descriptor, and several threw or
truncated unconditionally on the first call. This surfaced as an
intermittent macOS CI failure: node:test's own IPC channel back to the
parent process (which also goes through fs.writeSync internally) could get
a bogus injected error or truncated write if node's internal machinery
called it while one of these mocks was active, corrupting the message
frame the parent tried to deserialize ("Unable to deserialize cloned
data.", location tests/io.test.cjs:1:1, uncaughtException — a whole-file
IPC crash, not a test assertion failure).

Root cause confirmed by a working counter-example already in the same
file: the "#3912 A6" mocks gate on `fd !== 2` before any fault injection
and were never implicated. Applied the same fd-scoped pattern to the five
unscoped mocks (four output()-targeting tests gate on fd 1, one
error()-targeting test gates on fd 2), and added a regression test proving
an unrelated fd passes through untouched while the fault-injection mock is
active.

Found while verifying #3661; unrelated to that change's own diff.

2131fe13f3 enhance(#3464): exec() detection widening, citation-debt cleanup — Phase 8 (#4171)
* feat(#3464): widen no-source-grep to detect regex.exec() on tracked text

Adds an execCall kind alongside the existing regexTest detection --
regex.exec(tracked) was invisible to the rule while regex.test(tracked)
was already caught, despite both reading a source-derived string through
a regex. Measured: 4 previously-invisible sites across 2 files.

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

* test(#3464): migrate 4 sites newly flagged by the exec() widening

docs-hooks-table-parity.test.cjs's three regex-extraction loops are
site-scoped marked (source-text-is-the-product) -- the dynamic
preToolEvent/postToolEvent dialect branching they mirror is explicitly
documented as not statically parseable, so a literal-pattern mirror is
the practical minimum-cost check.

no-bare-gsd-tools-command-position.test.cjs's readRouterVerbs() now
requires HOST_COMMAND_ROUTERS directly instead of regex-walking
gsd-tools.cjs's source text -- the same accessor three other suites
already use.

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

* fix(#3464): pay down 6 grandfathered uncited allow-test-rule markers

Two were genuinely load-bearing (suppressing a real detected violation)
and just needed a citation added -- phase6-capstone-conformance.test.cjs,
runtime-name-policy.test.cjs, both now (#3464).

Four were dead-weight file-header markers suppressing nothing -- each
file's real effective sites are covered by separate, already-cited
markers elsewhere in the same file. Deleted outright rather than cited,
per Phase 1's own precedent (remove non-load-bearing markers instead of
grandfathering them forever) -- codex-config.test.cjs (two copies),
gsd-check-update-worker-platform-gate.test.cjs, orphaned-hooks.test.cjs,
settings-jsonc.test.cjs.

allowlist.json: 134 -> 128 entries.

* chore(#3464): re-baseline effective-exemption ceiling to 84

The exec() widening's 3 newly-marked sites are now suppressed and
counted; ceiling rises 81 -> 84, the exact measured high-water mark.

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

* fix(#3464): correct citation and restore a wrongly-deleted marker

Two review corrections, both found by the orthogonal review pass:

- docs-hooks-table-parity.test.cjs's 3 new exec() markers cited #3464
  (mechanically "the phase that widened the rule") when the file's own
  established, correct reference is #3839 (the issue this whole test
  exists to enforce, already cited in its file header) -- fixed to match.

- gsd-check-update-worker-platform-gate.test.cjs's deleted file-header
  marker was NOT dead weight: its codeOnly() helper wraps readFileSync
  and is called inline as an assert argument, a genuine source-grep
  pattern on real .cjs/.js source that the rule cannot currently see
  (helper-function indirection is a distinct blind spot from anything
  Phase 7/8 measured) -- CONTRIBUTING.md is explicit that "unverified"
  is not the same as "vestigial." Restored, site-scoped this time
  (directly above codeOnly(), not as an inert file-header comment) and
  cited (#3103, the issue the file's own docstring already references).

codex-config.test.cjs's two deletions and orphaned-hooks.test.cjs's /
settings-jsonc.test.cjs's deletions were independently re-verified and
stand: their flagged lines read generated .toml/.json OUTPUT, not
source, or have no residual pattern at all.

9b77320580 fix(#4076): add missing gsd-hook-version header to gsd-node-runner.sh (#4092)
* fix(#4076): add missing gsd-hook-version header to gsd-node-runner.sh

gsd-node-runner.sh was registered in MANAGED_HOOKS but shipped without a
gsd-hook-version header, so gsd-check-update-worker.js always classified it
as 'definitely stale' (a missing header is indistinguishable from a
pre-version-tracking file). Every install on an otherwise up-to-date
version showed a permanent, unclearable '⚠ stale hooks — run /gsd-update'
warning naming this one file.

Root cause: the build-hooks.js comment claimed the file is 'not a
registered hook' and 'staged verbatim — no templating', but it IS in
MANAGED_HOOKS (managed-hooks-registry.cjs:34) and install.js already
stamps {{GSD_VERSION}} into every .sh hook unconditionally, gsd-node-runner.sh
included. The comment contradicted both the registry and the installer's
actual behavior, and the header line itself was simply never added.

Fix: add the header (matching every other managed .sh hook's format) and
correct the comment so it no longer asserts the opposite of what the
registry and installer actually do.

Adds a regression test that iterates every MANAGED_HOOKS entry and asserts
it carries a header matching the worker's own detection regex, so a future
hook added to the registry without one fails CI instead of shipping
silently.

Fixes #4076

* chore(#4076): add changeset fragment for PR #4092

* fix(#4076): address review nits — drop unneeded exemption, fix blank line

Per @trek-e's review on #4092:
- tests/managed-hooks.test.cjs:96: the readFileSync call uses a loop
  variable (entry-derived hookPath), not a literal path, so
  local/no-source-grep's static literal-path detector never flags it —
  the allow-test-rule exemption comment was unnecessary. Replaced with a
  plain note explaining the source-read rationale.
- tests/managed-hooks.test.cjs:121-122: dropped a stray extra blank line
  before the bug #2136 section divider.

b0572c0108 feat(#3674): extract shared file-overlap wave partitioner (#4166)
* test(#3674): characterize existing wave-dispatch output and add tests for the extracted partitioner

Pins resolveWaveDispatch's and emitWorkflowScript's current, unextracted
output (chain-overlap, disjoint-empty-set, and a multi-wave/multi-stage
golden script) as a regression safety net ahead of extracting
partitionStages into a standalone module. Also adds the new module's
unit and property tests (test matrix rows 1-11) against its expected
public API, which does not exist yet and is added in the next commit.

* feat(#3674): extract file-overlap partitioner into a shared, generic module

Moves partitionStages' greedy first-fit file-overlap algorithm into a new,
dependency-free src/file-overlap-partitioner.cts module (partitionByFileOverlap),
generalized over a plain {id, files}[] shape rather than claude-orchestration.cts's
Plan/Wave interfaces. partitionStages becomes a thin adapter mapping its own
Plan[] shape onto the generic input and back — behavior-preserving, no dependency
ordering, no path normalization, no filesystem access moved or added. Enables a
future consumer (quick-batch, #3675 / ADR-1239) to reuse the same primitive
without pulling in orchestration internals.

* docs(#3674): register the file-overlap-partitioner module bookkeeping

New src/*.cts -> bin/lib/*.cjs modules need four hand-maintained
registrations beyond the code itself: .gitignore (compiled artifact),
eslint.config.mjs (ADR-457: lint the .cts, not the emitted .cjs),
docs/INVENTORY.md's CLI Modules roster row (regenerated via
gen-inventory-manifest.cjs --write), and a CONTEXT.md glossary entry
matching the convention set by similarly-scoped leaf modules
(text-lines.cts, plan-dependency-graph.cts, spec-section.cts).

* fix(#3674): alphabetize INVENTORY.md row, manifest regen no-op, fast-check import already correct

- docs/INVENTORY.md: move file-overlap-partitioner.cjs row to alphabetical position
- docs/INVENTORY-MANIFEST.json: regenerated via gen-inventory-manifest.cjs --write,
  produced no diff (manifest is keyed by content, not row order)
- tests/claude-orchestration.test.cjs's direct require('fast-check') is correct as-is:
  tests/helpers/fast-check-setup.cjs's own docstring scopes the shared-seed wrapper to
  "every *.property.test.cjs file"; claude-orchestration.test.cjs is not a .property.test.cjs
  file, and every .property.test.cjs file sampled uses the wrapper consistently. No outlier.

* fix(#3674): constrain the no-overlap property test to unique ids, fixing an ambiguous duplicate-id reconstruction

The `no two plans in the same stage share a modified file` property
reconstructs which physical item produced each output id via
`remaining.findIndex(r => r.id === id)`. Under duplicate ids (an
explicitly-supported input shape for `partitionByFileOverlap`) that
reconstruction can pick the wrong physical occurrence, producing a
false-positive overlap failure (observed counterexample: p0(f1),
p208(f1), p208([]) — correctly staged as [[p0,p208#2],[p208#1]], but
misread by id-order as [[p0,p208#1],...], which do overlap).
Properties (a) determinism and (b) totality already exercise
duplicate ids correctly and are left unchanged; only this property's
generated items are now constrained to unique ids via
`fc.uniqueArray`, where the reconstruction is unambiguous.

fa107c0461 fix(#4172): add --merge-async to test:coverage:scripts-floor (#4173)
* fix(#4172): add --merge-async to test:coverage:scripts-floor

The "Coverage gate (merged shards)" test.yml job has OOM-crashed (exit
134, SIGABRT) on every push to next since 4dfc46b. test:coverage:scripts-floor
was the only c8 coverage-merge invocation in package.json still missing
--merge-async: c8's default sync merge path (Report._getMergedProcessCov)
loads every raw V8 coverage file from the merged 3-shard coverage/tmp
directory into memory as one array before merging, instead of folding
them in one at a time, and now blows through the job's 8192 MB heap
ceiling.

This is the same bug class as #4068 (fixed in 4d70b4dc4), which added
--merge-async to test:coverage:unit and test:coverage:report -- the two
other scripts sharing this merge/report code path -- but missed this
third sibling, which reads the exact same merged coverage/tmp data in
the same job. check-coverage and report both dispatch through c8's
shared getCoverageMapFromAllCoverageFiles()/mergeAsync branch, so the
fix is identical in shape to #4068's.

Extends the existing #4068 regression guard (tests/c8-merge-async-flag.test.cjs)
to also assert test:coverage:scripts-floor carries --merge-async, closing
the coverage gap #4068 left on this sibling script.

Fixes #4172

* docs(#4172): backfill changeset PR number (pr:0 -> 4173)

* fix(#4172): route scripts-floor through `c8 report`, not `check-coverage`

The prior commit (1a3d6b75e) added --merge-async to
test:coverage:scripts-floor, but the Coverage gate job still OOM-crashed
identically on PR #4173's CI run
(https://github.com/open-gsd/gsd-core/actions/runs/33587951779/job/100118358975).

Root cause of that miss: c8@11.0.0's `check-coverage` CLI subcommand
handler (node_modules/c8/lib/commands/check-coverage.js) never forwards
argv.mergeAsync into the Report constructor -- only the `report`
subcommand's handler (node_modules/c8/lib/commands/report.js) and the
default command (which also calls into report.js) do. Verified directly
by constructing Report the same way each handler does: the check-coverage
path yields report.mergeAsync === undefined even with --merge-async on
the command line, while the report path yields true.

Fix: route test:coverage:scripts-floor through `c8 report --check-coverage`
instead of `c8 check-coverage`. report.js's outputReport() calls the same
checkCoverages() threshold-checking helper when --check-coverage is
truthy, so behavior (and exit code on threshold failure) is unchanged --
only the code path taken to get there now actually honors --merge-async.

Extends the tests/c8-merge-async-flag.test.cjs regression guard with an
explicit assertion that scripts-floor invokes `c8 report`, not
`check-coverage`, so this can't silently regress back to the broken form.

Fixes #4172

* test(#3995): diff base keys on the phase directory, not commit subjects

All three derivation sites (Tier 3, spawn_reviewer, fallow pre-pass)
must anchor on the phase directory's first commit; the milestone-blind
repro (an archived milestone's same-numbered phase commit capturing
the base) is the failing-first row. #3191/#3503 rows reworked to the

* fix(#3995): derive the review diff base from the phase directory

A phase number is unique within a milestone, not a repository; the
message grep had no milestone bound and tail -1 deliberately selected

into the scope (7 files to 3388 plus the >50 depth downgrade). All
three lockstep sites now anchor on the first commit that added anything
under the phase own directory — the same anchor class

647365faf1 fix(#4011): key the TDD runtime gate on TDD_MODE alone (#4180)
* test(#4011): TDD gate keys on TDD_MODE alone, not the MVP intersection

Contract updates: no shipped line may conjoin MVP_MODE with TDD_MODE as
a gate condition, the end-of-phase escalation must not require MVP, the
executor agent's gate section triggers on TDD_MODE alone, and the gate
semantics reference loads without MVP_MODE.

* fix(#4011): key the TDD runtime gate on TDD_MODE alone

The RED-commit gate shipped as #76's MVP slice kept the paired
invocation's conjunct, so workflow.tdd_mode=true was silently inert on
every non-MVP phase, contradicting references/tdd.md's own contract.
Drops the MVP conjunct from the per-task gate and the end-of-phase
review escalation; rescopes execute-mvp-tdd.md's load condition,
gsd-executor's gate section, and mvp-concepts' intersection claim.
MVP remains free to imply TDD; the file is not renamed (stated
assumption in the PR body).

* test(#4011): scope no-conjunct detector to shell conditions; clean stale MVP+TDD phrasing

Review follow-ups: the detector now only inspects if/[ condition lines
so explanatory prose mentioning both flags cannot trip it; remaining

Behavioral coverage: extract the trailers:key token from ship.md and

which git's trailer machinery cannot tokenize, so the audit read was

Add additive typed fields to 5 hook scripts' PreToolUse/PostToolUse
advisory output alongside the existing additionalContext prose:

- gsd-read-guard.js: code ('READ_BEFORE_EDIT'), fileName
- gsd-context-monitor.js: severity ('warning'|'critical')
- gsd-prompt-guard.js: findings ([{ruleId, match}], module-local RULE_IDS
  + renderFinding mapper mirroring gsd-read-injection-scanner.js's #3523
  pattern)
- gsd-read-injection-scanner.js: severity ('LOW'|'HIGH'), source (its
  findings array already existed from #3523)
- gsd-workflow-guard.js: code ('WORKFLOW_ADVISORY') on the advisory leg,
  distinct from the existing force-add block leg's code

additionalContext stays byte-identical in every hook (verified per-hook
against the pristine HEAD version across a spread of payload shapes).

Migrates all 20 assertion sites named in the issue off
additionalContext.includes(...)/assert.match(...) substring-matching
onto the new typed fields, per CONTRIBUTING.md's prohibition on raw
text matching on test outputs.

Surfaced by gsd-test on the #3546 checkpoint: `commitN()`'s loop called

each call used DEFAULT_GIT_TIMEOUT_MS (15s) -- a bound git-fixture.cjs's
own doc comment says is sized for plumbing reads (rev-parse/branch/log),
not write-heavy add/commit spawns. That file already documents the exact
same defect class from a prior incident (PR #3323) and exports

f16ff7d1b3 enhance(#3545): widen no-source-grep with fold+hooks, migrate 76 sites (#4161)
* feat(#3545): widen no-source-grep with one-hop path-fold and hooks dir

Resolve a readFileSync() path argument that is a bare Identifier one hop
back to its VariableDeclarator initializer before classification, and
recognize `hooks` as a source directory alongside bin/lib/gsd-core/src.

Measured (epic #3464 phase 7): fold+hooks together newly flag 76
unsuppressed sites across 18 files that were previously invisible to
identifier-indirected or hooks/-rooted source reads. Neither widening
alone is sufficient — hooks-only surfaces 0 new sites, confirming #3520's
prior finding that the identifier-indirection gap must close first.

* test(#3545): migrate 76 sites newly flagged by the fold+hooks widening

Per-site classification: rewrite behaviorally (require() the real module,
assert on its actual exported behavior) wherever the read was a proxy for
code behavior; add a site-scoped `// allow-test-rule: <reason> (#3545)`
marker only where the raw source text genuinely is the product under test
(codex-config.test.cjs's adapter-header-contract checks, install.js
structural-wiring guards with no exported symbol, AST-parse fixture
inputs, etc.) — each marker cites an existing repo-sanctioned category
from CONTRIBUTING.md's allow-test-rule exception table.

Also converts two try/finally test bodies (introduced during this same
migration) to the required t.after() cleanup pattern per CONTRIBUTING.md.

* chore(#3545): re-baseline effective-exemption ceiling to 81

The fold+hooks widening's own newly-detected sites are now suppressed by
site-scoped markers, moving them from invisible into the tightly-ratcheted
effective-exemption count. Ceiling rises from 10 to 81 (the exact measured
high-water mark, grace unchanged at 2) — a deliberate, measured re-baseline
per the widening working as intended, not an ordinary ceiling bump.

* fix(#3545): use canonical allow-test-rule category tokens

4 markers added during migration cited an issue ref correctly but didn't
use one of CONTRIBUTING.md's seven recognized category tokens, unlike
every other marker in this change. Cosmetic only — same suppression
lines, same effective/live counts (81/81, 0 live).

ff0361071d feat(#3653): add review.models.cursor — wire modelArg/modelConfigKey for the cursor reviewer lane (#4160)
* feat(#3653): add review.models.cursor — wire modelArg/modelConfigKey for the cursor reviewer lane

cursor-agent exposes --model (204 selectable models) but the cursor lane
declared modelArg: null / modelConfigKey: null, so review.models.cursor
was rejected as an unknown config key and the #1517 reviewer-instances
escape hatch silently discarded a configured model at modelExpansion.

Wire the lane the same way codex already is: inject {{model}} into args
right after -p, set modelArg to --model, and declare modelConfigKey as
review.models.cursor plus its config schema entry. An unconfigured lane
still invokes byte-identically to today.

gsd-test surfaced three surfaces still hardcoding "cursor declares no

  invariant test listed cursor among lanes that must own no model key.
- tests/settings-integrations.test.cjs: the #3651 keyless-lane test
  listed cursor as keyless, including a live config-set assertion that
  now correctly succeeds instead of failing (swapped to qwen).

bf4485ada2 enhance(#3717): make the edge probe's shape cues language-aware via an optional text_en field (#4156)
* test(#3717): add failing-first coverage for text_en language-aware classification

Adds unit tests for the not-yet-implemented text_en field on Requirement
(fallback selection, empty/whitespace/non-string rejection, shapes-override
precedence), a SHAPE_CUES/VALID_SHAPES parity guard (RULESET.GENERATIVE-FIX),
and workflow-prose contract tests asserting spec-phase.md Step 5.5 documents
populating text_en for response_language projects. All new tests are RED
until src/edge-probe.cts and the workflow docs are updated.

* feat(#3717): make edge-probe shape classification read an optional text_en field

Requirement gains an optional text_en; classifyShape's own signature stays
untouched (a locked, directly-tested export), and the text_en ?? text
selection is pushed to proposeEdges' single call site instead. text_en is
validated fail-closed: an empty or whitespace-only value throws rather than
silently winning the ?? fallback and degrading classification to zero shapes.

This makes the #2773 doc-only translation convention an explicit,
validatable field instead of an invisible instruction, per the approved
Form-1 scope on #3717.

* docs(#3717): document the text_en field across spec-phase, reference and how-to docs

Updates Step 5.5's response_language instructions, the edge-probe reference
Inputs contract, the FEATURES.md fragment, and the non-English how-to guide
to describe the new text_en field: text keeps the requirement's own wording
in all cases, text_en (when populated) is the engine-only English rendering
the classifier prefers.

* docs(#3717): record the text_en locked-surface change in CONTEXT.md and ADR-550

Updates the Edge Probe Module glossary entry to describe the text_en field
and its fail-closed validation, and appends an ADR-550 amendment recording
why this is additive and does not re-open the #652 LLM-classifier rejection
(text_en is a plain field read by the existing deterministic regex
classifier, not a new model-dependent surface).

* docs(#3717): add changeset fragment and regenerate FEATURES.md

pr:0 placeholder — backfilled with the real PR number after the PR opens.

* docs(#3717): attribute the text_en machine check to engine-level validation, not prose tests

Code-review (Spec axis) finding: the workflow-prose contract tests and the
ADR-550 amendment overclaimed themselves as "the machine check the #2773
doc-only stopgap lacked." That check is actually engine-level
(validateRequirement/classifyShape, covered in tests/edge-probe.test.cjs) —
the prose tests are the same style of assertion #2773 already used. Reworded
both to attribute the claim correctly.

* fix(#3717): rewrap spec-phase.md so the id-unchanged sentence stays on one line

The #3717 rewrite of Step 5.5's response_language paragraph moved a line
break so "requirement `id`s" ended one physical line and "are never
translated" started the next. The pre-existing #2773 regression test
(tests/edge-probe-spec-phase-contract.test.cjs) asserts id + "never
translated" on the SAME line (no \n in between, matching git's own
line-oriented prose), so the reflow silently broke it. Rewrapped so the
sentence lands on one line again, verified against every #2773/#3717
regex assertion in that test file.

Emitted-Drift-Ack-Growth: spec-phase.md — #3717 adds text_en documentation to Step 5.5 (response_language paragraph + REQS_JSON heredoc comment); this growth is this PR's own diff, not incidental drift.

4dfc46bbe7 enhance(#3348): add a context-drift pre-check gate to plan-phase (#4147)
* test(#3348): add failing-first coverage for the context-drift gate

* feat(#3348): add context-drift pre-check gate for plan-phase

Compares each phase's *-RESEARCH.md/*-PATTERNS.md/*-VALIDATION.md/*-SPEC.md
effective last-changed time (git commit time, falling back to mtime for
uncommitted edits) against *-CONTEXT.md's, so plan-phase no longer silently
reuses an upstream artifact that predates a decision added to CONTEXT.md
after that artifact was derived from it. Deterministic, no model call.

New `gsd_run verify context-drift <phase>` command, sibling to the existing
verify.codebase-drift/verify.schema-drift gates in the drift capability.
Warn-only by default (workflow.context_drift_precheck), with an opt-in
workflow.context_drift_action: block escape hatch. Wired at plan:pre in
plan-phase.md, before both the RESEARCH.md and PATTERNS.md reuse decisions.

* fix(#3348): address code-review findings — raw-text-match, stale comment, import placement, duplicated phase resolution

* fix(#3859): pin the real commit's diff.ignoreSubmodules to match the empty-diff probe

The #3859 empty-diff guard decides whether a submodule bump would land using
`--ignore-submodules=dirty`, overriding the caller's `diff.ignoreSubmodules`
config. The real `git commit -- <paths>` that follows was never given the
same override, so under a bare `diff.ignoreSubmodules=all` repo config the
two calculations disagree: driven on git 2.39.5 (Debian bookworm, the
linux-node24 test-matrix image), the guard correctly stands aside but the
scoped commit itself then silently fails (exit 1, no error text) for a
gitlink bump it had just confirmed would be recorded, surfacing as
commit_failed instead of committed:true.

Pin `-c diff.ignoreSubmodules=dirty` onto the scoped commit call too, so the
probe and the commit it protects can never diverge. Harmless when no
submodule path is involved (driven: identical outcome on an ordinary scoped
file, with and without the flag).

* fix(#3348): guard resolvePhaseDirByToken's exact-match fallback against path traversal

* fix(#3348): retarget phase-enumeration-drift exemption to the consolidated resolvePhaseDirByToken helper

cmdVerifySchemaDrift's inline readdirSync was already function-scoped-exempt
in lint-phase-enumeration-drift.cjs as a single-phase LOOKUP (not a
current-milestone enumeration). This PR's refactor pass lifted that block
into a shared helper, resolvePhaseDirByToken, also used by the new
cmdVerifyContextDrift — the guard tracks exemptions by enclosing function
name, so the readdirSync now lives in an unexempted function and started
firing. Move the exemption to resolvePhaseDirByToken (same written reason,
now covering both callers) instead of migrating to listAllPhaseDirs, which
would introduce two real behavior deltas here: it catches readdirSync
failures internally (old code let them throw) and sorts results by phase
number before matchPhaseDirs picks matches[0] (old code used raw,
OS-dependent readdirSync order).

* fix(#3348): satisfy lint:ci — slash form, capability registry regen

- docs/features/context-drift-gate.md used the deprecated /gsd: colon
  form; docs are never passed through the install-time slash-form
  converters, so lint-docs-command-form requires the hyphen form.
  Regenerated docs/FEATURES.md from the corrected fragment.
- Regenerated gsd-core/bin/lib/capability-registry.cjs after editing
  capabilities/drift/capability.json (lint:generated-sync).

* fix(#3859): pin the real commit's diff.ignoreSubmodules via env, not argv -c

The prior fix pinned `-c diff.ignoreSubmodules=dirty` onto the scoped commit's
argv via `commitArgs.unshift(...)`. `-c key=val` must precede the `commit`
subcommand, so this shifted `commitArgs[0]` from `'commit'` to `'-c'` for
every scoped commit call, breaking 17 position-based assertions in the
commit-files pathspec regression suite that read `a[0] === 'commit'` to find
the commit invocation among recorded git calls.

`execGit` already accepts an `env` option merged onto `process.env` before
spawning. Git honors `GIT_CONFIG_COUNT`/`GIT_CONFIG_KEY_0`/`GIT_CONFIG_VALUE_0`
as a per-invocation config override functionally identical to `-c key=val`,
expressed via env instead of argv. Passing that env alongside the existing
commitArgs (still `['commit', ..., '--', ...stagedPaths]`, argv unchanged)
fixes the real commit's effective diff.ignoreSubmodules to match the
empty-diff guard's probe without moving anything in argv position 0. Scoped
to exactly the canScope branch, matching the probe's own preconditions and
leaving no behavior change for commits the probe never evaluated.

No test file changes needed — the 17 previously-failing assertions test
argv[0] against the array passed into execGit, which never changes.

* fix(#3348): register verify-context-drift in the check subcommand router

The drift capability's new plan:pre gate declares check.query
"verify.context-drift", which normalizes to `check verify-context-drift`,
but no such subcommand was routed — phase6-capstone-conformance's
uniform-block-field test failed with "Unknown check subcommand" for
every declared gate query.

* fix(#3348): extend #1592's exact-key-list snapshot for the new context-drift config keys

tests/capability-registry.test.cjs asserted an exact, hardcoded snapshot
of the drift capability's config keys. #3348 legitimately adds two new
keys (workflow.context_drift_precheck, workflow.context_drift_action)
for its own plan:pre context-drift gate — extend the expected set
(and clarify the assertion message) without weakening the test's
exactness.

* fix(#3348): reconcile E2's exemption-migration pin with the resolvePhaseDirByToken extraction

#3348 (an earlier commit on this branch, e4b80ad81) extracted
cmdVerifySchemaDrift's inline phasesDir readdirSync/matchPhaseDirs block
into the shared resolvePhaseDirByToken helper (also used by the new
cmdVerifyContextDrift), and retargeted lint-phase-enumeration-drift.cjs's
function-scoped exemption from cmdVerifySchemaDrift to
resolvePhaseDirByToken accordingly — cmdVerifySchemaDrift no longer
contains a line the guard's detectors match, so it needs no exemption.

tests/phase-locator.test.cjs's E2 test still pinned the exemption to the
old name (cmdVerifySchemaDrift), unaware of the migration. Update E2 to
match the same "migrated call site's exemption must move, not
duplicate" pattern the test already applies to cmdRoadmapAnalyze and
cmdInitMilestoneOp just below it: drop cmdVerifySchemaDrift from the
still-exempt list and add symmetric assertions that it no longer
carries the exemption while resolvePhaseDirByToken now does.

* fix(#3348): fix two self-contradicting/nondeterministic tests in context-drift.test.cjs

'always exits 0 (query command contract)' included the no-phase-arg
case, which contradicts the file's own earlier
'errors with usage message on missing phase arg' test (that case
legitimately exits 1 via the Usage error) — drop it from the
always-exits-0 cases.

'degrades to mtime comparison outside a git repo' and '...in a repo
with no commits' relied on real wall-clock ordering between two
back-to-back writeFileSync calls to prove CONTEXT.md is newer than
RESEARCH.md; on a fast filesystem both can land in the same mtime
tick, producing a tie that computeContextDrift's strict `<` correctly
treats as not-stale, so stale_artifacts comes back empty. Make both
tests deterministic via explicit fs.utimesSync instead of relying on
timing (CONTRIBUTING.md: never assert elapsed wall-clock time).

c0fd2e3f4c feat(#3673): add dispatch.maxConcurrency axis and dispatch-capacity query (#4162)
* test(#3673): add failing tests for dispatch.maxConcurrency axis and dispatch-capacity CLI route

Extends tests/host-integration.test.cjs with negotiateHostCapabilities
maxConcurrency negotiation coverage (test matrix rows 1-15, including a
fast-check property test) and a new #3673 dispatch-capacity CLI route
describe block spawning the real gsd-tools.cjs (rows 16-25). Extends
tests/host-integration-validator-parity.test.cjs with an all-19-descriptor
maxConcurrency presence/validity sweep (row 26) and adds a hostile-input
validator test to host-integration.test.cjs (row 27).

The dispatch.maxConcurrency field does not exist yet, so these tests fail.

* feat(#3673): add dispatch.maxConcurrency axis, negotiation, validator parity, and the dispatch-capacity query

Adds a numeric dispatch.maxConcurrency sub-field to the Host-Integration
Interface (ADR-1239 Phase 1), following the existing dispatch.isolation
sub-field pattern: DispatchCapability interface, SAFE_DEFAULTS/PROFILE_BASELINES
floors, and a negotiateHostCapabilities branch that passes through a positive
safe integer and fails closed to 1 otherwise (no engine-side reduction, per
the design doc's explicit rejection of a min(host,engine) rule).

capability-validator.cjs gains parity validation for the new field (optional,
positive safe integer or the "undocumented" sentinel — mirroring isolation's
"added after existing descriptors" treatment).

gsd-tools.cjs gains a new `query dispatch-capacity` route, a pure-read sibling
of `dispatch-isolation` with no side effects: live env
(GSD_DISPATCH_MAX_CONCURRENCY) > descriptor > fallback-to-1 precedence.

All 19 capabilities/*/capability.json descriptors now declare
dispatch.maxConcurrency: claude carries the one cited value (20, per
code.claude.com/docs/en/sub-agents); the other 18 carry "undocumented"
(not yet researched for this axis).

* docs(#3673): document dispatch.maxConcurrency and add its citation row to the capability matrix

Updates docs/reference/host-integration-interface.md's dispatch struct entry
(also backfilling the previously-undocumented isolation/backgroundDispatch
sub-fields found stale in the same table) and adds fail-closed/live-transport
precedence prose for the new maxConcurrency field.

Adds a dispatch.maxConcurrency row (with citation) to all 19 host sections in
docs/reference/host-integration-capability-matrix.md — required for
tests/host-integration-descriptors.test.cjs's kimi-code matrix-parity check,
which asserts every declared dispatch sub-axis is documented there.

Updates docs/how-to/add-or-update-a-host-integration.md's dispatch checklist
and example descriptor block to mention maxConcurrency (and, likewise
backfilling a stale gap, isolation/backgroundDispatch).

* fix(#3673): extract shared maxConcurrency validator, drop dead reserved-name check

Exports isPositiveSafeInteger from src/host-integration.cts as the single
source of truth for the dispatch.maxConcurrency positive-safe-integer
contract; negotiateHostCapabilities and gsd-tools.cjs's routeDispatchCapacity
now both call it instead of independently reimplementing the same predicate.

Also removes the __proto__/constructor/prototype reserved-name branch from
capability-validator.cjs's maxConcurrency check — copy-pasted from the
string-enum fields above it, but unreachable for a numeric field (the
generic positive-safe-integer branch already rejects any string) and absent
from maxDepth, the field the code's own comment claims to mirror.

b848b23861 feat(#3778): dispatch plan:pre planner contributions before quick planning (#3934)
* feat(#3778): dispatch plan:pre planner contributions in quick.md

- Add plan:pre capability gate to quick.md Step 5, mirroring plan-phase.md's
  existing render + generic contribution dispatch pattern
- Inject planner-targeted contribution fragments into the planner prompt,
  after AGENT_SKILLS_PLANNER, matching D-08 ordering
- Add tests/quick-plan-pre-capabilities.test.cjs proving the dispatch is
  generic (D-01) via real scanWiredKinds/coveredKindsInRegion functions
- Record quick.md's byte-growth rationale in this commit trailer for every
  gsd-core-verbatim runtime

Emitted-Drift-Ack-Growth: quick.md — #3778: Step 5 (Spawn planner, quick mode) gains a `plan:pre` capability gate, mirroring `plan-phase.md:420-424` and `:797`. This is shipped shell and prose read by an agent at runtime, not compiled, so the reasoning has to travel with the feature rather than being deferred to a reference doc: (1) the dispatch paragraph phrases role routing possessively ("the role each entry's `into` names") rather than as an `into ==` equality, because `coveredKindsInRegion` (scripts/gen-loop-host-contract.cjs) voids a segment's `kind == "contribution"` coverage credit when a role or capability equality shares that same segment — an equality phrasing here would silently fail the generic-dispatch proof required by D-01; (2) `activeHooks` is read directly in-context from `PLAN_PRE_HOOKS_JSON`/`HOOKS_JSON` and the unfiltered `rendered` digest is explicitly forbidden from being pasted, because `rendered` carries every kind and role — including non-planner-targeted contributions such as a `into: "checker"` twin — and pasting it would leak checker-scoped guidance into the planner's prompt (T-01-02 in the threat model); (3) the injection block sits inside `<planning_context>` AFTER `${AGENT_SKILLS_PLANNER}` and after the Project skills line, matching plan-phase's `:741` -> `:797` ordering (D-08), so agent-skills content is never shadowed by capability-contributed prose. No prose was moved into an eagerly `@`-imported reference to shrink the measured file — @gsd-core/references/loop-hook-dispatch.md already existed before this change and is deferred to for the generic contract only, exactly as plan-phase.md already does.

* test(#3778): expand quick.md plan:pre dispatch coverage to all nine locked conditions

Extend tests/quick-plan-pre-capabilities.test.cjs with D-02 (silent
omit-when-empty), D-03 (single shared planner spawn), D-06 (array-order
dispatch phrasing), D-07 (planner-only into filter), and D-08 (render call
< agent-skills placeholder < injection block < spawn ordering) assertions,
all extracted via a brace-bounded slice anchored on the literal injection
instruction rather than a naive first-brace scan (${AGENT_SKILLS_PLANNER}
and the surrounding prompt's ${VALIDATE_MODE ? ...} ternaries also contain
brace pairs).

Add a capability-registry.test.cjs describe block proving the registry-wide
D-07 exclusion is meaningful: at least one plan:pre contribution exists,
every plan:pre contribution has a non-empty into/fragment.inline, and the
registry as a whole carries at least one non-planner-into contribution.

Add a loop-host-contract.test.cjs regression pin for D-09: quick.md stays
absent from STEP_WORKFLOWS, parseLoopHostBlock still throws on quick.md's
real content, and buildContract() still yields exactly 5 entries.

Verified red-without-Task-1 by temporarily reverting quick.md to its
pre-f30de9cc content and re-running these three suites (D-08 failed as
expected), then restored via git checkout and re-confirmed green.

* docs(#3778): note quick planning also renders plan:pre in the tutorial

The tutorial's Step 6 named only /gsd-plan-phase as the trigger for the
plan:pre hook set. Since quick.md now dispatches the same hook set
(f30de9cc), the sentence understated the capability's real reach.

* feat(#3778): add changeset fragment

* chore(#3778): reference the upstream issue in the changeset fragment

The fragment was the only one of 81 in .changeset/ without a trailing
(#NNNN) reference or a bold lead-in. serializeChangelog auto-appends
only the pr: field, so the rendered CHANGELOG entry carried no link
back to issue #3778.

* test(#3778): scope the D-07 registry assertion to what it actually proves

The registry-wide non-planner check was named "D-07 exclusion is
meaningful", which overclaims: it proves only that `into` takes
non-planner values somewhere in the registry, not that anything is
excluded at plan:pre. Every plan:pre contribution is currently
into: "planner", so the filter is a forward-looking safeguard there.

Narrowing the assertion to plan:pre (as review suggested) would fail
today. Asserting plan:pre is all-planner would be brittle — it would
break the day a legitimate non-planner plan:pre contribution lands,
which is exactly when the safeguard starts doing work. So the
assertion is unchanged and only the name and comment are corrected.

* chore(#3778): point the changeset fragment at the upstream PR

The fragment carried pr: 3, the fork staging PR. changeset lint derives
the real PR number from GITHUB_EVENT_PATH, so on the upstream PR that
would read as pr-field drift. Point it at open-gsd/gsd-core#3934.

4c6643a8d7 fix(#3945): require a non-empty denominator for milestone-complete (#4164)
* test(#3945): 0-of-0 milestone counters must not render complete

Regression coverage for the string-truthiness vacuous equality in both
statusline renderers: '0' counters, boundary 1/1 vs 0/1 vs 1/0, compact
parity.

* fix(#3945): require a non-empty denominator for milestone-complete

Both statusline renderers compared the regex-captured string counters
directly, so '0' && '0' && '0' === '0' fired Scene 3 on the empty set.
Numeric coercion plus total > 0 restores the guard's intent; all
non-zero shapes and percent=100 render byte-identically.

c9bff8d2b9 fix(#3899): resolve REVIEWS.md by quoted assignment, not an unquoted ls (#3928)
* fix(#3899): resolve REVIEWS.md by quoted assignment, not an unquoted ls

The convergence loop resolved the phase REVIEWS.md through
`$(ls ${phase_dir}/... 2>/dev/null)`. The unquoted ${phase_dir} word-splits,
so a project path containing a space handed `ls` arguments that do not exist,
the discarded stderr hid the error, and the empty result was reported as
"review agent did not produce REVIEWS.md" — blaming the agent for a quoting
defect. A glob metacharacter fails worse: the pattern expands to whatever
sibling directory matches, so the loop silently reads a different phase's
REVIEWS.md and `ls` still exits 0.

Assign the path directly, quoted, and fail closed with an error that names the
expected location. The regression block extracts the bash fence from the
shipped workflow and RUNS it against space-, glob- and missing-file fixtures,
because every text assertion in that suite passed against the broken line.

* chore(#3899): add the changelog fragment

* fix(#3899): reject a non-file reviews path and anchor the gate harness

Adversarial review (codex, gemini) on the first cut, three findings taken:

- `[ -r ]` alone is true for a readable DIRECTORY, so a directory standing
  where the reviews file belongs passed the gate and reached the consumers
  that read it. Require a regular file as well.
- the harness picked its fence by scanning the WHOLE document for a bash
  block assigning REVIEWS_FILE. If the real fence ever stopped assigning it
  and an unrelated one started, the harness would execute the wrong block and
  report green. Anchor the span to the verification step, between its opening
  sentence and the next heading.
- the no-subshell assertion matched only `$(`; a backtick rewrite would
  reintroduce identical word-splitting unseen. The discarded-stderr assertion
  is scoped to lines naming REVIEWS_FILE rather than banning the redirect
  across the whole fence.

Four findings declined: `return 1 || exit 1` (the document's own idiom is a
bare `exit 1`, including the guard immediately below), `${phase_dir:-}` for
`set -u` (unchanged exposure from the old line, and an unset phase_dir is a
bug worth surfacing), an explicit empty-phase_dir branch (the guard already
fails closed and prints the truncated path), and a downstream
`[ -n "$REVIEWS_FILE" ]` hazard (no such consumer exists — the guard exits
before any of them run).

* chore(#3899): backfill the changeset PR number

* fix(#3899): address required review feedback

Use the fragment-aware workflow reader, remove the inert exemption marker, document the unreadable-arm coverage limit, align errors with the workflow convention, and name an empty phase_dir directly. Migrate the obsolete emitted-drift fragment to the current commit-trailer contract.

Emitted-Drift-Ack-Growth: plan-review-convergence.md — #3899: replace unquoted $(ls ... 2>/dev/null) resolution with a quoted direct path, fail-closed file/readability checks, and an explicit phase_dir diagnostic; surrounding prose records why quoting is load-bearing.

b6dd4e2e74 fix(#3936): dispatch quick research with researcher persona and model (#4158)
* test(#3936): quick research dispatch must use researcher persona/model

Regression tests for the planner-persona leak in quick's Step 4.75
research dispatch: init quick emits researcher_model, the workflow
resolves AGENT_SKILLS_RESEARCHER and parses researcher_model, and the
researcher dispatch uses the researcher persona/tier while planner and
executor dispatches keep their own.

cmdInitQuick now emits researcher_model (parity with the plan-phase
init), quick.md resolves AGENT_SKILLS_RESEARCHER and parses the new

{planner_model} for the researcher's own persona and tier. The #2517

eca9c2b590 fix(#4112): portable grep in workflow markdown + submodule commit fix under diff.ignoreSubmodules (#4149)
* fix(#4112): ban GNU-only grep -P in workflow markdown to prevent macOS regressions

Add scripts/lint-portable-grep.cjs, wire it into lint:ci, and add
tests/lint-portable-grep.test.cjs. The #4112 shell-syntax fix newly exposed
a pre-existing grep -oP invocation that silently resolves to "" on stock
macOS's BSD grep (no -P support). This ratchet catches the same class of
GNU-coreutils assumption before it merges, mirroring lint-portable-timeout.cjs.

* fix(#4112): drop unneeded ls -l long-format that broke basename/dirname extraction

The previous commit on this branch replaced grep -oP 'phases/\K[^/]+'
(GNU-only, silently fails on macOS's BSD grep) with
basename "$(dirname "$phase")"), but left ls -lt (long format, -l) in
place. -l output is a full detail line (permissions, owner, size, date,
path), not a bare path, so dirname on that string throws "illegal
option -- r" (BSD) / errors under GNU coreutils too -- the extraction
never produced a usable value, on any platform. -l was never needed
here; only mtime-sort plus the bare path mattered. Dropping it to
ls -t restores one-bare-path-per-line output, which basename/dirname
actually requires. Confirmed on gsd-test's Linux bench: the #4112
regression test (tests/pause-work-context-detection.test.cjs) now
passes phase, spike, and sketch resolution.

Emitted-Drift-Ack-Growth: pause-work.md — portability fix (#4112): dropping grep -oP for a portable basename/dirname extraction is a few characters longer per line; no functional growth beyond the fix.
Emitted-Drift-Ack-Growth: sync-skills.md — portability fix (#4112): replacing grep -oP '(?<=--from )\S+' with a portable sed -E capture-group equivalent (no PCRE lookbehind available) is a longer expression; growth is the direct cost of the fix, not new functionality.

* fix(#3859): pin git commit itself against diff.ignoreSubmodules=all, not just the probe

git 2.39.x (the exact version on the CI Linux bench) resolves a
pathspec-scoped `git commit -- <path>` through the same
diff.ignoreSubmodules-gated machinery as `git diff`, so a genuinely
bumped submodule gitlink was silently dropped by the real commit even
though the #3859 empty-diff probe correctly saw the change. The commit
was misclassified as generic commit_failed because git's refusal text
never says "nothing to commit". Prefix the pathspec-scoped commit
invocation with -c diff.ignoreSubmodules=dirty, the same override the
probe already carries, so the two can no longer disagree. Confirmed on
git 2.50.1 (no-op) and git 2.39.5 via the actual gsd-tester-linux
v1.8.0-node24 bench image (turns the silent refusal into a commit).

* fix(#3859): carry the diff.ignoreSubmodules override via env, not argv

The prior commit prepended `-c diff.ignoreSubmodules=dirty` to the real
commit's argv, which shifted `commitArgs[0]` off `'commit'` and broke
several pre-existing #3859 regression tests
(tests/commit-files-pathspec.test.cjs) that assert on the raw argv
captured at the execGit seam, e.g. `gitCalls.some((a) => a[0] ===
'commit')`. Carry the same override via `GIT_CONFIG_COUNT` /
`GIT_CONFIG_KEY_0` / `GIT_CONFIG_VALUE_0` env vars instead, which git
honours identically and leaves argv untouched. Re-confirmed on the
gsd-tester-linux v1.8.0-node24 bench (git 2.39.5): the submodule commit
still succeeds.

* test(#3859): pin the commitEnv GIT_CONFIG_* override to canScope directly

The commitEnv/GIT_CONFIG_* override added in e935694fc/b3d37b929 was only
exercised indirectly through pre-existing submodule integration tests. Add
two dedicated regression tests that pin the canScope=false side of the
scoping decision: a whole-index commit (no --files) and an --amend commit
must both keep recording a bumped submodule gitlink under
diff.ignoreSubmodules=all with no override applied, since neither shape
carries a pathspec for that git internal check to consult.

* fix(#4112): match grep invocations after then/do/else/elif shell keywords

lint-portable-grep.cjs's GREP_INVOCATION_RE only anchored to line-start or
right after `| & ; ( \` {`, so a grep call positioned right after `then`,
`do`, `else`, or `elif` (e.g. `if x; then grep -oP '...'; fi`) was never
flagged, letting the GNU-only grep -P defect this lint exists to catch
reappear undetected in that shape.

* fix(#3859): apply the diff.ignoreSubmodules override to every commit, not just scoped ones

The commitEnv GIT_CONFIG_* override landed in e935694fc/b3d37b929 only when
canScope was true, on the assumption that git 2.39.5's silent refusal of a
bumped submodule gitlink under diff.ignoreSubmodules=all only affects a
pathspec-limited `git commit -- <paths>`. Reproduced directly against the
pinned CI tester image (ghcr.io/open-gsd/gsd-tester-linux:v1.8.0-node24,
git 2.39.5): a bare whole-index `git commit -m ...` with no pathspec at all
is refused identically when the only staged change is a submodule gitlink,
since git's "nothing to commit" check is a real diff against HEAD that
honours diff.ignoreSubmodules regardless of whether a pathspec narrows it.
Apply the override unconditionally instead of gating it on canScope; it
remains a confirmed no-op for --amend, which never hits this refusal at
all. Caught by the new regression test added in 579ac9f8f, which failed
against the real bench git version before this change.

* fix(#3859): apply diff.ignoreSubmodules override to commit-to-subrepo and pr-subrepo

cmdCommit already carries the GIT_CONFIG_* override that forces
diff.ignoreSubmodules=dirty on the actual git commit call so a bumped
submodule gitlink is not spuriously refused under git 2.39.5. The two
sibling multi-repo commit paths, cmdCommitToSubrepo and cmdPrSubrepo,
build the identical canScope-branched commit invocation but never
carried the override, so the same refusal there surfaces as a generic
commit_failed/error instead of a recorded gitlink. Apply the override
unconditionally to both, matching the corrected cmdCommit shape.

* fix(#3859): pin pr-subrepo's change detection against diff.ignoreSubmodules

cmdPrSubrepo discovers what to commit via `git status --porcelain`, which
(like the empty-diff probe fixed for cmdCommit) honors a local
diff.ignoreSubmodules=all config. Under that config, a genuinely bumped
submodule gitlink is invisible to the status scan, so changedFiles comes
back empty and the function reports nothing_to_commit before ever reaching
the commit call this same issue already fixed. Pin the status probe with
--ignore-submodules=dirty, mirroring the flag cmdCommit's diff probe already
uses, so a real gitlink bump is detected regardless of local config.

Found while adding a regression test for the previous #3859 follow-up fix:
the test failed not on the commit step but on this earlier detection step.

bdfc62889b fix(#3784): read the hybrid Current Plan: N of M shape, keep zero-padding, and name the accepted shapes on failure (#3791)
* fix(state): read the hybrid "Current Plan: N of M" shape

advancePlanCore derived the value FORMAT from the field NAME, so it
handled the legacy pair (`Current Plan` + `Total Plans in Phase`) and the
compound `Plan: N of M`, but not the hybrid of the two: the legacy field
name carrying a compound value with no Total Plans sibling. `legacyTotal`
is null so the legacy branch fell through, and the compound branch reads
the `Plan` field through a `^Plan:`-anchored pattern that never matches
`Current Plan:`. Both produced NaN against a file whose plan numbers are
plainly readable.

The shape is not exotic. An agent wrote it unprompted into a project's
STATE.md, believing it was the parseable form, and every subsequent run
in that project inherited the failure and worked around it by hand.

Track the field name and the value shape separately (`planSourceField`,
`planRawValue`) so write-back targets whichever field the value came
from. The legacy pair still takes precedence when both fields exist, so
a stray "of N" inside Current Plan cannot override an explicit Total
Plans — covered by a new test.

Also replace the caller's catch-all error. It reported "Cannot parse
Current Plan or Total Plans" for ANY transition failure, and named no
accepted shape, so a reader learned neither what failed nor what to
write. It now distinguishes "no result" from "unreadable plan position"
and lists all three shapes. The existing test asserted the literal
"cannot parse"; it now asserts the message names the shapes, which is
the property that makes it actionable.

* fix(state): keep zero-padding when advancing a compound plan value

The compound write-back rewrote only the leading half of "N of M", so a
padded value drifted lopsided: "04 of 06" advanced to "5 of 06". Cosmetic
on its own, but a plan line that looks wrong is one the next writer tidies
by hand, and hand-tidying this particular line is what produced the hybrid
shape the previous commit had to teach the parser to read.

Pad the incremented number to the width it was written with. padStart never
truncates, so a value that outgrows its padding widens correctly: 09 of 12
advances to 10 of 12. Unpadded values are untouched — 2 of 6 still advances
to 3 of 6.

Claude-Session: https://claude.ai/code/session_016QHxbMHTPYbEqAnKTpJPR8

* fix(state): pass a literal field name to the compound write-back

The previous commit passed `planSourceField` — a variable — as the field-name
argument to `stateReplaceField`, which trips the state-write-path drift guard's
`unstripped_content_write` axis (ADR-3408 §8.3(b)). The guard is right to care:
a Title-Case literal cannot collide with a lowercase or snake_case frontmatter
key, so it is safe whatever the content argument is, while a variable could
hold anything and therefore requires its content to be demonstrably
frontmatter-stripped first.

The content argument here IS stripped — `body` is `stripFrontmatter(content)` —
but the guard does a narrow backward scan rather than dataflow tracking, by
design, and the nearest preceding assignment to `body` is another
`stateReplaceField` result. Rather than baseline a bypass or ask a future
reader to re-derive that the invariant holds, dispatch on the discriminator and
pass the literal.

Guard goes from 1 finding to 0; its own 32 tests pass.

Claude-Session: https://claude.ai/code/session_016QHxbMHTPYbEqAnKTpJPR8

* test(#3784): cover the maintainer's AC1 write-back and AC6 reader-anchoring

Triage published six acceptance criteria; two were only half-covered.

AC1 asks that the hybrid write back to the SAME field with padding preserved.
The existing hybrid test used an unpadded value and asserted only `result.data`,
so it proved the parse but never the write. Now asserts the written content is
`05 of 06` on the original field, and that no separate `Plan:` field appears as
a side effect.

AC6 asks that the shared field reader not be loosened. Reading the hybrid is the
transition's job; `stateExtractField('Plan')` is line-anchored and has 13+
callers, so teaching it to match a name merely ENDING in "Plan" would be the
wrong fix and would silently change what those callers read. This holds by
construction here — the reader is untouched — but nothing locked it in. The new
test fails if anyone later reaches for that shortcut.

Also drops the changeset fragment written against the auto-closed PR number.

* fix(#3784): write the advanced plan back to the field it was read from

Review findings 2-6 on #3791 were one defect seen from several angles: the
read path learned the hybrid `Current Plan: N of M` shape, the write path
did not follow it.

- `bumpLeadingNumber` now owns the increment for all three parse branches.
  Only the leading digits belong to this transition; the padding width and
  everything after it (` of M`, and the `\r` of a CRLF file) are the
  author's text and are preserved. The legacy branch wrote `String(newPlan)`,
  which turned `2 of 99` into `3` and `04` into `5`.
- `mutateCurrentPositionForAdvance` takes the plan field NAME. Its plan arm
  only ever looked for `Plan:`, so on a hybrid file the `## Current Position`
  section was never reached; combined with the body-level write being
  single-shot and bold-preferring, a file carrying the field at both sites
  advanced the header and left the section a plan behind. The parameter
  defaults to `Plan`, so the two callers that pass no plan are unchanged.
- Tests: both-sites-advance (fails without the section arm), legacy
  write-back content assertions (the previous test read only `data` and so
  could not see the lossy write), hybrid boundary at limit-1 and limit+1, a
  CRLF fixture, and an fc property pinning the padding-width contract.

Two characterization tests pinned `**Current Plan:** 02` advancing to `3`.
That dropped padding is the defect #3784 reports, so the expectation is
corrected to `03` rather than the fix being narrowed around it.

* fix(#3784): drop the unreachable advance-plan error branch, sync the doc

Findings 1 and 8 on #3791.

The `!resultData` arm could not fire: the transform callback assigns
`resultData` unconditionally, only runs once STATE.md is known to exist (the
missing-file case returns "STATE.md not found" upstream), and every
`advancePlanCore` return path sets `data`. It was a speculative second
failure mode with a message no caller could receive, and the comment beside
it claimed to distinguish two things that were never two. `!resultData`
stays in the condition as a type guard, which is all it ever was.

`docs/json-errors.md:142` quoted the old error literal verbatim and was the
sole occurrence in the tree; it now quotes the emitted one.

* chore(#3784): describe the write-back fix in the changeset

* fix(#3784): anchor the plan grammar and widen the schema row to match

Review round 3 on #3791: B1, B2, M1, M2, M3, M4 and the planSourceField nit.

B1 — `STATE_FIELD_SCHEMA.current_plan.acceptedShapes` widens to
`['N', 'N of M']`, which is what `src/state-md-schema.cts`'s own comment
instructed this PR to do on merge. `'N/M'` stays undeclared so row 23 keeps a
non-vacuous undeclared candidate to probe. Verified `gen-state-md-docs
--check` exits 0 and `--write` rewrites 0 of 6: the generated artifacts do not
surface this row, so there is nothing stale to regenerate.

B2/M4 — the discriminator was `/of\s+(\d+)/`, unanchored, so a total could be
read out of prose. `Current Plan: 4 — blocked on review of 2 PRs` parsed as
`4 of 2`, took the `currentPlan >= totalPlans` branch and WROTE
`Status: Phase complete — ready for verification` into the user's file. Both
shapes are now anchored at the start and every number comes from a capture
group via `planNumberFrom`, which rejects anything past `Number.MAX_SAFE_INTEGER`
rather than letting `data` and the persisted string disagree. Nothing on this
path calls `parseInt` on a raw field value any more.

The grammar keeps a trailing remainder after the total, because
`Plan: 2 of 5 in current phase` is a real tested shape. The refusal comes from
requiring `of <total>` to follow the leading number immediately, not from
forbidding a suffix.

M1 — `bumpLeadingNumber` is total. It returned its input unchanged when there
were no leading digits, so `+2` reported `advanced: true` while writing the
file untouched.

M2 — both section arms use replacer functions. File-derived text was being
spliced into a `String.replace` replacement string, where `$&` / `` $` `` /
`$'` expand: a value of `04 of 06 $&` spliced part of the document into itself.
`stateReplaceField` already used a function; these now agree with it.

M3 — the section arm targets the name the SECTION carries, and the body write
now writes both spellings, each with its own rendering. Keying off the header's
name left the other name stale in both directions: a legacy header beside a
`Current Plan:` section line, and a `**Plan:**` header beside one.

* fix(#3784): derive the shape error from the schema, widen the test coverage

Review round 3 on #3791: B3, m1, m2, m5 and the two test nits.

B3 — the accepted-shape set had two owners: the parser branches and an English
list hand-written beside them in `state.cts`. Nothing coupled them, so adding a
branch left the message stale and removing one left it advertising a shape that
errors, with no test able to see either. The message is now built from
`STATE_FIELD_SCHEMA.current_plan.acceptedShapes`, and the CLI test walks the
schema instead of restating the list. `Plan: N of M` is still spelled out
explicitly because no schema row owns the body-only `Plan` field —
`buildStateFrontmatter` never reads it into frontmatter, so it has no key to
hang a row on.

m1 — the property drove only the pre-existing `**Plan:**` branch, i.e. not the
branch under review. It now drives both compound spellings and ranges past 99
so the width transition is covered by the property rather than one example. A
second property covers the legacy pair's own preservation contract. Both were
mutation-checked: dropping the padStart turns 9 tests red.

m2 — degenerate boundary fixtures around the threshold (`0 of 0` is
phase-complete, not an error; `0 of 3` advances) plus the shapes the anchored
grammar must refuse, including Arabic-Indic digits.

m5 — `docs/json-errors.md` described rather than quoted the message, since it
is now schema-derived and a verbatim quote would be a third owner.

Nits — the CRLF assertion could not see a `\n` at index 0; the
`!/^Plan:/m` presence proxy is now an identity assertion on the whole
`## Current Position` body.

* fix(#3784): give the section plan write its own flag, and stop narrowing what parses

Review round 4 on #3791: Blockers 1-4, Majors 1-2, Minors 1-2.

B1 — the section fallback was guarded by `!mutated`, and `mutated` is
FUNCTION-wide, already set by the phase/status/lastActivity arms that
`advancePlanCore` always populates. A section spelling the field bold or as a
pipe-table row therefore skipped its fallback because an UNRELATED field had
been refreshed, and stayed a plan behind the header — the split-brain document
this arm exists to prevent. The arm now tracks its own `planWritten`.

Worth recording: the reviewer's fixture does not reproduce. The body-level
status write lands on the section's own `Status:` when the document has no
header `Status:`, so `mutated` is still false by the time the plan arm runs and
the fallback fires. The discriminating shape needs a header `Status:` to absorb
that write AND a bold section plan line. The mechanism was right; the example
was not, and the regression test uses the shape that actually fails.

B2 — `fallbackName` chose one name by ternary. In the legacy shape both values
are populated, so it always chose `Current Plan` and a `**Plan:**` section line
— which base did write — got nothing. Each name is now attempted independently
with its own fallback.

B3 — `PLAN_SHAPE_N` was anchored harder than `PLAN_SHAPE_N_OF_M`, so values base
parsed via `parseInt` began to hard-error: `Total Plans in Phase: 5 phases`,
`Current Plan: 3 (blocked)`. #3784's brief puts normalizing plan numbers beyond
this transition's read/write out of scope, so that narrowing was not licensed.
Both grammars now carry the same trailing tolerance. The prose defect stays
closed by the START anchor, not by forbidding suffixes.

Major 1 — the whole-body `Plan` write is scoped to documents that declare a
`Plan` field, instead of firing unconditionally where `stateReplaceField`'s
first match could be prose outside `## Current Position`.

Major 2 — the error message names both `Plan` spellings the parser accepts; it
previously omitted the sibling-paired form, which is the same
message-disagrees-with-parser drift the derivation exists to close.

B4 — the changeset claimed a guarantee B1 broke; it now describes what ships.

Minors — safe-integer boundary coverage at limit-1/limit/limit+1, and the CRLF
comment states the real mechanism (`stateExtractField`'s `(.+)` stops before the
CR; the trailing group is belt-and-braces, not the primary defence).

All three blocker regression tests verified red against the pre-fix source.

* test(#3784): pin the hybrid shape against #3807's ambiguity refusal

#4028 landed `advance-plan`'s multi-`Phase:` refusal on `next` after this
branch's last run, on the same function. The guard sits above the parse, so
a refused document is never parsed and the shape #3784 adds cannot reach the
mutation — but that is a property of source ordering, so assert it as
behaviour instead.

Fail-first proven, not assumed: with `phaseCandidates.length > 1` disabled,
the ambiguous hybrid document advances its FIRST entry's
`Current Plan: 04 of 06` to `05 of 06` and writes it — #3807's exact defect,
reached through #3784's shape. Both tests go red; both go green with the
guard restored.

The control pins the other direction: an unambiguous hybrid section still
advances, and its zero-padding still survives.

* fix(#3784): advance every spelling from its own text, refuse when they disagree

Round 6 review. B1 and M1 are one defect, so they are one fix.

`advancePlanCore` picked one field to parse from, computed `newPlan`, then
wrote BOTH spellings from that field's numbers. Two symptoms:

  B1  With `Plan` as the parse source, `Current Plan` was re-stamped with
      the number just derived from `Plan`. `Current Plan: 7` beside
      `Plan: 2 of 5` silently became `Current Plan: 3` — a value nothing
      derived for that field, no error, no diagnostic.
  M1  With the legacy pair winning, the `Plan:` line was re-rendered from
      a bare `${newPlan} of ${totalPlans}` built out of the sibling field.
      `Plan: 2 of 9` became `3 of 5`; `Plan: 03 of 05` became `4 of 5`.
      The changeset's claim that padding and everything after it survive
      was true only for whichever field happened to be the parse source.

Now: every spelling is advanced from its own raw text via
`bumpLeadingNumber`, so each keeps its own padding, its own total and its
own trailing annotation. Differing TOTALS are preserved, not reconciled —
`Plan: 2 of 9` beside a `Total Plans in Phase: 5` advances to `3 of 9`.

Differing CURRENT numbers are refused, with `reason:
"ambiguous_plan_position"` and both candidates named. Same posture as
#3807's multi-`Phase:` guard one field over: name the conflict, let the
caller resolve it, never pick. The guard sits immediately after the parse,
BEFORE the phase-complete branch — guarding only the normal advance would
let `Current Plan: 7` beside `Plan: 5 of 5` write a terminal "Phase
complete" into a document whose two spellings never agreed.

A field present but unreadable (`Plan: TBD`) is left exactly as authored.
Refusing the whole document because an unrelated line cannot be read would
be a narrowing #3784 does not license; writing a derived number over it is
the fabrication B1 was filed for.

The `planSourceField`/`planRawValue`/`useCompoundFormat` tracking is gone.
It existed only so the write path could ask which field the value came
from, and the write path no longer asks.

M2. The bare `Plan: N` + `Total Plans in Phase: M` shape is dropped. A
revision of this PR added it; base refused it. It cannot be given the
schema-row + forcing-test coupling the other shapes have, because `Plan`
is body-only and `buildStateFrontmatter` never reads it into frontmatter,
so there is no `current_*` key to hang a row on. Parser, the spelling in
`advancePlanShapeError`, and the lockstep test move together — the
invariant is the lockstep, not the length of the list.

N1. The whitespace narrowing (`5phases` no longer parses where `parseInt`
read 5) is documented in the changeset beside the other deliberate
narrowings, rather than loosened. Loosening restores the half-parse this
change exists to remove.

Tests: eight new cases plus a property that crosses the two spellings with
agreeing and disagreeing numbers — the review noted the existing
properties never did. Fail-first proven: restoring the old write path
reddens seven of the eight, both new property arms, and two pre-existing
padding tests.

* fix(#3784): report Current Plan as updated only when it was written

The write became conditional in the previous commit — a `Current Plan:`
that is present but unreadable is left as authored — but the `updated`
push stayed unconditional, so `transitionCore` reported a field it had not
touched. `reconcileReportedFields` would have caught it against the
persisted bytes at the `state.cts` caller, but `transitionCore`'s own
`updated` is consumed directly (milestone-lock, the transition tests) and
has to be true on its own.

Covers the mirror of the unreadable-spelling case: `Current Plan: TBD`
beside a readable `Plan: 2 of 5`, where `Plan` is the parse source and the
legacy field is the one that cannot advance. Fail-first proven.

* test(#3784): account for the new refusal in the output({error}) census

`tests/io.test.cjs`' A3 census asserts the exact population of
`output({error})` call sites in `src/`, per module. The
`ambiguous_plan_position` refusal added a 27th to `state.cts`, so the
census went red at 26/65.

Updated the way #3807 updated it when it added the ambiguous-POSITION
error one line above: bump the count and name the addition inline, so the
next person reads why the number is what it is. The alarm did its job —
it is the only gate that noticed a new user-visible error path had been
introduced.

7c116b1c17 fix(#3697): warn when the phase-complete Requirements-line tokenizer under-selects REQ-IDs (#3744)
* fix(#3697): warn when the Requirements line under-selects REQ-IDs

`cmdPhaseComplete` tokenizes ROADMAP's `**Requirements**:` line by splitting
on `[,\s]+` and keeping tokens matching the anchored REQ-ID shape. That is
correct for the canonical comma list the template ships, and silently wrong
for every other form:

  `RANGE-01 … RANGE-05`  ->  the two ENDPOINTS only; the interior IDs are
                             never considered, yet `requirements_updated`
                             reports true with zero warnings
  `RANGE-01…05`          ->  ZERO IDs; the whole line is inert

The silence is structural: the only cross-check, `ghostReqIds`, is itself
`citedReqIds.filter(...)`, so an ID the tokenizer dropped is invisible to it
by construction — and to `traceabilityWriteMisses` and `requirements_updated`
with it.

Warn on both paths. This does not add range support: the selected set is
unchanged, so no existing ledger write changes. The trigger is ID-SHAPED
EVIDENCE only — an ID-shaped substring the tokenizer did not select, or a
range operator joining two IDs — with parenthetical citations and HTML
comments stripped before the scan, so the #2334/#2339 over-warning on
`None`, on the shipped `<!-- brackets optional -->` template comment, and on
annotated lines cannot return.

Regression tests extend the #2316/#2334 fixture family in tests/phase.test.cjs
(10 cases: 4 defect, 2 canonical controls, 4 negative-space controls).

Fixes #3697

* fix(#3697): rework under-selection detection onto tokens, not a free-text scan

Round 2, driven by the P4.6 cross-AI review (codex, gpt-5.6-sol) of b3ce71cb.
That review refuted 5 of 9 claims; three were false-positive classes in exactly
the category #2334/#2339 had to REMOVE:

  `RANGE-01, RANGE-02 - 3 points`        the bare-hyphen alternative read
                                         `RANGE-02 - 3` as a range
  `REQ-01, REQ-02 — locked per ADR-7.`   the trailing period kept `ADR-7.` out
                                         of the anchored filter, so the
                                         unanchored substring scan reported it
                                         as unparsed
  `REQ-01, REQ-02 (see (ADR-7), then ADR-8)`
                                         nested parens left `ADR-8)` behind

Replaces the free-text substring scan + loose range regex with three narrow,
token-based rules (R1 range-shaped token, R2 pure range operator flanked by two
selected IDs, R3 zero-selection with ID-shaped text). Also fixes the review's
CLAIM 9: the warning said IDs were "marked complete" when a ghost range marks
nothing — it now says "selected".

Side effect: the two false NEGATIVES the same review found are now covered —
`RANGE-01 through RANGE-05` and a parenthesised `(plus RANGE-02..RANGE-05)`.

NOT YET DONE (see the handoff prompt): regression tests for the four false
positives, the two new true positives, and the #3697-4 tightening the review's
CLAIM 8 asked for (it currently filters on the warning's phrasing rather than
asserting silence). Verified so far: tsc clean, the 10 existing #3697 tests
green, and a 20-case standalone harness covering every case above.

* test(#3697): pin the v2 token-detector boundary end-to-end

Six new cases + two hardenings for the review findings against v1:

- #3697-1 gains the worded spaced range (`RANGE-01 through RANGE-05`) —
  the operator set's `to|thru|through` arm was previously untested.
- #3697-5 (new): a tight range hidden inside balanced parentheses
  (`RANGE-01 (plus RANGE-02..RANGE-05)`) warns, names the range token,
  and ticks exactly RANGE-01 — the paren shave must not hide it.
- #3697-4 gains the four false-positive classes a free-text detector
  produced: numeric estimate (`- 3 points`), date annotation, em-dash
  citation with trailing period (`— locked per ADR-7.`), and nested
  parenthetical citations.
- #3697-3 and #3697-4 now assert the ENTIRE warnings channel is empty,
  not that one phrase is absent — a re-worded over-warning cannot pass.

Negative control: against the merge-base with its lib rebuilt, all 6
defect tests fail and all 10 controls pass.

* fix(#3697): close round-2 review findings — annotation false positives

Round 2 of the adversarial review (against 822a72a04) refuted five
claims; this closes the false-positive class and the cheap misses:

- R1's bare-hyphen arm now demands a full ID on BOTH sides
  (`REQ-01-REQ-05`): `LETTERS-\d+-\d+` is also a date-like annotation
  (`FY-2026-08`) and a sub-numbered ID, and warning on those is the
  expensive class. Tight hyphen shorthand with a live selection is the
  disclosed false negative; at zero selection R3 still catches it.
- R2 requires the endpoint pair to imply an INTERIOR (same prefix,
  gap > 1): `REQ-02 - REQ-03` selects both endpoints and can drop
  nothing, so an annotation hyphen between adjacent IDs stays silent.
- R3 skips placeholder-led lines: `None (per ADR-7)` is a declared-empty
  line citing its rationale, not unparsed residue.
- Token shave: quotes/backticks now shaved from alphanumeric tokens
  (`` `RANGE-02..RANGE-05` `` warns); punctuation-only tokens get a
  bracket-only shave so `(..)` surfaces its operator.
- 256-char token cap bounds the quadratic unanchored substring test.
- Warning text mentions range expansion only when a range rule fired.

Tests: 6 new cases (22 total). Negative control against the merge-base:
8 defect tests fail, 14 controls pass.

* fix(#3697): close round-3 review findings — half-spaced ranges, cross-prefix annotations, markdown wrappers

Round 3 of the adversarial review (against 2eb92dd0e) refuted four
claims; this closes them:

- Half-spaced ranges (`REQ-01 -REQ-05`, `REQ-01- REQ-05`) split at the
  tokenizer before R1's `\s*` can see them and under-selected silently.
  A glued-fragment rule warns when an operator is glued to a full ID
  with an ID-shaped neighbour on the open side and the endpoint pair
  implies an interior.
- Cross-prefix pairs around a separator no longer read as ranges:
  `REQ-02 - (ADR-7)` and `REQ-02 (...) (ADR-7)` are annotations, and
  real ranges are same-prefix by nature. `impliesInterior` now returns
  false on prefix mismatch and computes the gap with BigInt (parseInt
  lost precision past 2^53).
- The token shave now removes markdown emphasis markers and curly
  quotes, so `**None** (per ADR-7)` reaches the placeholder gate and
  `**RANGE-02..RANGE-05**` reaches R1.
- The unanchored-substring cap rises to 2048 (a markdown-link range
  with a long URL cleared 256); the anchored range regexes scan
  linearly and drop their cap.

Tests: 6 new cases (28 total; 377/377 file-wide). Negative control
against the merge-base: 11 defect tests fail, 17 controls pass.

* fix(#3697): round-4 review finding — word operators excluded from glued-fragment rule

`TOREQ-05` is a valid prefix-agnostic REQ-ID, and the glued-fragment
rule read it as `to` + `REQ-05`, warning on the canonical two-ID list
`REQ-01, TOREQ-05`. Glued fragments are now SYMBOL-operator-only
(`..`+, ellipsis, dashes): a word operator glued to an ID is an ID,
not a range spelling.

Tests: word-operator-prefixed ID control (misparse channel silent; the
fixture's ghost-ID warning legitimately fires, so the whole-channel
assertion stays with the registered controls) and an underscore-wrapped
tight-range defect case. 30 targeted cases; 379/379 file-wide; negative
control: 12 defect tests fail on the merge-base, 18 controls pass.

* fix(#3697): round-5 review findings — trailing word-op glue, dot shave, honest wording

- The glued-fragment TRAILING arm takes the word operators back: an ID
  must end in digits, so `REQ-01through` can never be an ID — the
  round-4 TOREQ collision was leading-arm-only, and symbol-only on both
  arms lost the `REQ-01through REQ-05` typo class.
- A trailing run of 2+ dots survives the punctuation shave: `REQ-01..`
  is a glued range operator, not sentence punctuation, and the shave
  was silently eating the `REQ-01.. REQ-05` form.
- The warning now says the line "could not be parsed as" a
  comma-separated REQ-ID list: `**REQ-01**, **REQ-05**` IS such a list
  — the selector just cannot parse decorated tokens — and a warning
  that misstates the input teaches readers to distrust it.

Tests: two new trailing-glue defect cases (32 targeted; 381/381
file-wide). Negative control: 14 defect tests fail on the merge-base,
18 controls pass.

* test(#3697): use t.after for cleanup per CONTRIBUTING test ruleset

CONTRIBUTING bans try/finally inside test bodies (it masks failures);
the approved shape is `t.after(() => cleanup(tmpDir))`. All seven
converted tests are this PR's own additions; the file's pre-existing
instances are untouched.

* chore(#3697): add changeset fragment for the Requirements-line under-selection warning

changeset-lint fails on this PR (fail_missing_fragment): src/phase.cts is a
user-facing surface and the branch carried no .changeset/*.md. Adds the Fixed
fragment via `npm run changeset -- --type Fixed --pr 3744`, symptom-led per
the house format, with the (#3697) backlink.

* refactor(#3697): extract the Requirements-line detector to a testable surface

Round-3 review Blocker 1 requires a fast-check property test over this
detector (`RULESET.TESTS.property-based-testing`: modules implementing
parsing contracts must include at least one), and Blocker 2 requires
limit-1/limit/limit+1 fixtures on its 2048-char token cap
(`RULESET.TESTS.boundary-coverage.fixtures`). Neither is expressible while
the logic is a closure inside `cmdPhaseComplete`: every existing #3697 test
reaches it by spawning the CLI, and a property test cannot pay a subprocess
per generated case.

So the selector and the three detection rules move to module scope as
`analyzeRequirementsLine` (pure, exported) plus
`formatRequirementsLineWarning`, and `cmdPhaseComplete` calls them. This
commit changes NO behaviour: `tests/phase.test.cjs` is untouched here, and
the pre-round suite passes against it unmodified (403/403).

Two things the move makes explicit rather than incidental. The selector and
the detector tokenize the SAME line DIFFERENTLY — the selector strips only
`[` and `]`, the detector also shaves quotes, emphasis and trailing sentence
punctuation — and that gap is deliberate: it is why `ADR-7)` is not selected
while `ADR-7` is still nameable in a warning. They now sit adjacent with the
reason written down, so they cannot drift apart silently.

And the stale citations in the moved comment are corrected. It pointed at
src/phase.cts:833,920,1078 for the `**Requirements**: TBD` seeds, which had
drifted to 1132/1237/1413, and at `templates/roadmap.md:32`, which is
`gsd-core/templates/roadmap.md:32`. Both are now anchored by content.

* fix(#3697): stop the warning claiming a misparse that did not happen

Round-3 review Major 3 and Minor 4. Both are the same defect: the warning
asserted more than the evidence supported.

MAJOR 3 — a correct comma list such as `RANGE-01, RANGE-02 — RANGE-05
deferred` warned "could not be parsed ... Range forms are not expanded;
rewrite the line". Reproduced: it selects RANGE-01, RANGE-02 AND RANGE-05,
i.e. every ID written on the line. Nothing was dropped, and the pinned
control only stayed silent because its pair was ADJACENT (gap == 1), so the
control was passing by accident of the fixture rather than by the rule.

The obvious fix — go silent — is not available. `RANGE-02 — RANGE-05` as a
range and as an annotation separator are textually identical, and no
token-level rule separates them; staying quiet re-opens the exact silent
under-selection #3697 is about. Deciding the ambiguity by assertion in
either direction is wrong. So it is DISCLOSED: the warning now has two
channels, chosen by whether any ID-shaped token was actually left unselected
(`droppedIdShaped`).

  * something was dropped (tight range, glued fragment, inert residue)
    -> "could not be parsed as a comma-separated REQ-ID list", as before.
  * nothing was dropped (only the spaced-operator rule fired)
    -> "contains what reads as a range between two cited REQ-IDs", stating
    both readings and saying explicitly that an annotation separator means
    the line is already correct.

This retires the "could not be parsed" wording for the four #3697-1 spaced
cases too, and that is a deliberate expectation change rather than a fix
counted twice: those lines never failed to parse either. They still warn,
still name the selected IDs, and still assert the endpoint-only marking is
unchanged; #3697-1 now also asserts the misparse channel stays SILENT.

MINOR 4 — `Deferred (see ADR-7)` reported `Unparsed text: ADR-7`, naming a
citation as requirement content it had failed to read. The trigger is
correct and stays: #3697's acceptance criterion asks for a warning "when it
selects zero IDs from a line that is non-empty and is not the `TBD`
placeholder", and inferring placeholder-ness from arbitrary prose is the
free-text heuristic this detector exists to avoid. What was wrong is the
wording, so the non-range arm now says "ID-shaped text that was not
selected" and names the escape the author actually has (`TBD` / `None`).

Tests: #3697-9 (three spaced forms — must warn, must NOT claim a misparse,
must offer both readings) and #3697-10 (`Deferred (see ADR-7)`, `N/A
(tracked in ADR-12)` — must warn, must not say "Unparsed text", must not
diagnose a range, must name the placeholder escape).

Reversion control: reverting the ambiguous channel fails #3697-9 (3 named
tests); reverting the R3 wording fails #3697-10 (2 named tests).

* fix(#3697): cap every token predicate, complete the dash set, cover the boundary

Round-3 review Blocker 2 and Nit 6, plus one self-found finding. All three
are about the detector's own predicates, so they land together.

BLOCKER 2 — the 2048-char budget had no boundary coverage.
`RULESET.TESTS.boundary-coverage.fixtures` requires limit-1 / limit /
limit+1 for any budget parameter. #3697-B1 and #3697-B2 now exercise 2047 /
2048 / 2049 against BOTH predicate families the cap guards, and each asserts
its fixture's exact length before asserting behaviour, so a mis-built
fixture fails loudly rather than passing at the wrong size. Clause (d) of
that rule — an input pushed within reserve-distance of the limit — has no
referent here: this is a hard cap with no reserve constant beside it, and
the test comment says so rather than leaving the omission to be re-derived.

NIT 6 — the cap guarded only the unanchored ID-substring regex. The
anchored range regexes were left uncapped, justified by a comment asserting
they scan linearly. The finding is right that this is informational (they
are anchored; the input is a local ROADMAP.md), but an asserted property is
cheaper to enforce than to defend, so all three predicates now share one
`short()` guard. #3697-B2 is what pins it: at 2049 the anchored scan must
now decline to classify.

SELF-FOUND (RV4 guard-shape census) — the range-operator set is a list this
code fixes at author time over a domain that grows without it, so the round
owes a census of what the enumeration reaches.

  reached:     `..`+, U+2026, U+2013, U+2014, ASCII `-`, to/thru/through
  NOT reached: U+2010 hyphen, U+2011 non-breaking hyphen, U+2012 figure
               dash, U+2015 horizontal bar, U+2212 minus sign
  consequence: a range spelled with any of those is SILENTLY under-selected
               — #3697's own defect, in the code that exists to fix it

Those five close. They are the same operator at a different codepoint and
carry none of the ASCII hyphen's collision risk, because they are not the
REQ-ID separator: `FY-2026-08` is date-shaped only with ASCII hyphens, so a
U+2010 never reaches the ID shape. They therefore join the NOHYPHEN arm
beside `—` and `–`; the strict full-ID-both-sides shape the bare hyphen is
held to is untouched, and #3697-12 pins that.

Still NOT reached, declined with reason rather than left unstated: `→`, `~`,
`..=`, `..<`, `until`, and `up to` (two tokens, so never one operator
token). Each is a symbol or word with an independent non-range use between
two REQ-IDs — the over-warning class #2334 cost three rounds.

Reversion control: reverting the uniform cap fails #3697-B2 (limit+1);
reverting the dash set fails #3697-11 (5 named tests).

* test(#3697): add the fast-check property coverage the parser rule requires

Round-3 review Blocker 1. `RULESET.TESTS.property-based-testing` (CONTEXT.md)
requires modules implementing parsing contracts to carry at least one
fast-check property test asserting a domain invariant, and the round-2 diff
had zero occurrences of `fc.` across its +311 test lines. Five properties,
1,900 generated cases:

  P1  soundness of silence (boundary containment) — for ANY canonical comma
      list of well-formed REQ-IDs, the selected set EQUALS the written set
      and nothing warns. This is the #2334 over-warning invariant and the
      #3697 under-warning invariant asserted as one statement, over
      generated IDs rather than hand-picked ones. It generalises #3697-4b:
      a prefix beginning with a word operator (`TORANGE-05`) is an ID, and
      P1 covers that class rather than the single example.
  P2  completeness — a same-prefix pair with an interior between them,
      separated by any of the nine spaced operators, ALWAYS warns.
  P3  the #2334 invariant — an ADJACENT pair around a separator can drop
      nothing, so it stays silent however it is annotated.
  P4  totality + idempotency — total over arbitrary strings, deterministic,
      and the formatter agrees with the analysis on whether there is
      anything to say (a warn with no text, or text with no warn, is a
      channel that can go silent or noisy on its own).
  P5  containment — every selected ID is ID-shaped and appears verbatim in
      the input.

Honest scoping, since a property test is easy to overclaim: P1, P3, P4 and
P5 hold against the round-2 code as well as this one — they are regression
guards, not bug-finders, and their value is that the invariants are now
stated and generatively checked rather than implied by examples. P2 is the
one that would have failed before the dash enumeration was completed.

fast-check v4 removed `fc.stringOf`, so the ID-prefix tail is built from
`fc.array(...).map(join)` with the alphabet pinned to the selector's own
`[A-Z0-9]` class.

These live in tests/phase.test.cjs rather than a new
`phase.property.test.cjs`: `lint-test-file-count` caps a production module
at 2 test files and phase.cts is already at its allowlisted entry, so a new
file would trade one gate for another.

* docs(#3697): document the ROADMAP Requirements-line grammar

Round-3 review Minor 5 — the change adds net-new user-visible warning output
for a grammar constraint documented nowhere under docs/. `type: Fixed` is
docs-exempt so this does not block, but a warning about a rule the reader
cannot look up is not actionable, and that is worth fixing whether or not a
gate demands it.

Added as a subsection of `phase complete` in docs/CLI-TOOLS.md, beside the
existing SUMMARY artifact-check advisory it is a sibling of: the supported
comma-list form, why ranges are deliberately not expanded, that `TBD` and
`None` are the entire placeholder vocabulary, and what each of the two
warning voices means — including that the range/annotation one may be
reporting a line that is already correct.

Existing file rather than a new one, deliberately: docs/ carries generated
indexes and zh-CN / ja-JP trees, and a new top-level page invites a parity
or index gate this change has no reason to touch.

* fix(#3697): rule-scope the warning-channel discriminator

Self-found at the round's pre-push review, against the Major 3 fix two
commits back. That fix chose the channel from a LINE-GLOBAL question — "was
any ID-shaped token left unselected?" — while the rules that produce the
warning are not line-global. The two disagree as soon as the line carries an
ID-shaped token no rule fired on:

  `RANGE-01, RANGE-02 — RANGE-05 deferred per (ADR-7)`

`(ADR-7)` survives the selector's bracket strip, so the global test called it
a drop and sent the line to the assertive channel — putting the false "could
not be parsed ... rewrite the line" claim back on a correct line. That is
review finding Major 3 returning through a side door, and it directly
contradicts #3697-4, which pins a parenthetical citation as NOT unparsed
residue.

The discriminator is now rule-scoped: R2 is the only ambiguous rule, so the
ambiguous channel requires that R2 fired, that no other rule did, and that
every endpoint R2 fired on was actually selected. The last conjunct is not
redundant — the detector shaves brackets and the selector does not, so R2 can
fire on a `(RANGE-02)` that was never selected, and that IS a drop:

  `RANGE-01 (RANGE-02) — RANGE-05`   -> assertive, correctly

`droppedIdShaped` is replaced by `spacedRangePairs` (R2's hits, so the
channel can ask about the endpoints the rule fired on) and the
`rangeReadingOnly` verdict.

Reversion control: against the line-global rule, #3697-9b fails. #3697-9c
passes under both rules — there the dropped token IS the R2 endpoint, so the
two agree; it is a regression guard, not a bug-finder, and is recorded as
such rather than counted as a second control.

* fix(#3697): hold every dash to the strict range shape, not just ASCII

Self-found at the round's pre-push review, and it CORRECTS a claim made two
commits back. That commit widened the range-operator set by five Unicode
dashes and asserted they "carry none of the ASCII hyphen's collision risk,
because they are not the REQ-ID separator". That reasoning was wrong. The
collision is a property of the SHAPE — `PREFIX-\d+ <dash> \d+` is also a date
(`FY-2026-08`) and a sub-numbered ID (`API-2-01`) — and the shape does not
care which dash sits in the operator slot, because the ID's own separator is
still ASCII either side of it. Measured:

  RANGE-01 (target FY-2026-08)   silent   <- pinned by #3697-4
  RANGE-01 (target FY-2026‐08)   WARNED   <- same line, U+2010

So the widening reintroduced the #2334 over-warning class on a date
annotation. It also exposed that the inconsistency PREDATES this PR: U+2013
and U+2014 were already in the loose arm at ce71dd399, so the en- and em-dash
forms of that same date annotation warned before round 3 ever ran.

One rule for every dash: a tight range spelled with any of the eight must
carry a FULL ID on both sides, exactly as the bare hyphen already had to.
`..`, `…` and the word operators stay loose — no date or sub-number reading
exists between two numbers, so the strict shape would cost them coverage for
nothing.

The cost is a false negative, and it is one the design already accepts:
`RANGE-01, RANGE-02-05` is silent today, deliberately, and now
`RANGE-01, RANGE-02–05` is too. That removes an inconsistency rather than
opening a gap, and a bare `RANGE-02–05` still warns — it selects nothing, so
R3 catches it.

Tests: #3697-13 (date annotation AND sub-numbered ID silent for all eight
dashes), #3697-13b (full-ID tight range still warns for all eight),
#3697-13c (loose operators keep their numeric endpoint), #3697-13d (the
accepted false negative is symmetric, and the bare zero-selection line still
warns).

* fix(#3697): close the round's own pre-push review findings

An adversarial cross-AI review of this round refuted 4 of its 10 claims. All
four were real. Every fix below is to code THIS round introduced.

1. THE SOFT VOICE CLAIMED TOO MUCH (refuted CLAIM 1).
   `REQ-01, (REQ-02), REQ-03 — REQ-05` took the range-reading voice and told
   the author "the line is already correct and nothing needs to change" — while
   `(REQ-02)` had been dropped by the selector, which does not strip
   parentheses.

   The channel choice is still right, and deliberately so: `(ADR-7)` and
   `(REQ-02)` are the SAME shape, so routing on "was anything unselected?" puts
   the false "could not be parsed" claim back on a line carrying a citation —
   the misroute fixed two commits ago. No rule can adjudicate this; the author
   can. So the voice stops asserting the line is correct (it now speaks about
   the SEPARATOR, which is all it has evidence about), and BOTH voices gained a
   factual clause naming ID-shaped text the selector skipped, with the reason
   (brackets are not stripped) and no verdict attached.

2. THE CAP SILENCED A LINE THAT USED TO WARN (refuted CLAIM 2).
   A 2049-char range token warned before this round and went silent after it:
   the "uniform cap" commit bounded the predicate and, with it, the warning.
   That is #3697's own defect, introduced by the fix for a nit.

   The cap bounds the WORK, not the warning. An over-cap token carrying `-` is
   now recorded as unclassified (a linear `includes`, never the unanchored
   regex the cap exists to keep off it) and gets its own voice: "could not be
   checked ... the REQ-ID selection on this line is unverified". Unclassified
   is reported, never treated as clean.

3. THE CAP WAS NOT UNIFORM (review MISSED finding).
   R2 capped the operator token but not its neighbours, so
   `<2049-char ID> .. <2049-char ID>` still ran REQ_ID_SHAPE_RE and BigInt over
   both endpoints unbounded. The glued rule had the same hole. Every
   participant is capped now.

4. PROPERTY P5 WAS VACUOUS (refuted CLAIM 5).
   It drew from a bare `fc.string()`, which over 500 samples produced max
   length 10 and ZERO inputs containing a REQ-ID — the loop body never executed
   an assertion. A containment property that never contains anything is a green
   test measuring nothing. The generator now interleaves real IDs with noise
   and the property ASSERTS it saw them (>50/500), so it can never silently go
   vacuous again. The free-form coverage it was actually providing survives,
   honestly labelled, as #3697-P6.

   The same finding refuted this round's claim that P2 distinguishes pre-round
   behaviour: every operator P2 uses was already in the pre-round operator set.
   P2 is a regression guard, and its comment now says so.

Also: docs/CLI-TOOLS.md repeated the broken channel claim verbatim (review
MISSED finding) and is corrected with the code.

Tests: #3697-9d (soft voice names the skipped ID, never claims the line is
correct), #3697-9e (over-cap token reported as unclassified, still warns),
#3697-9f (R2 and the glued rule cap their neighbours). #3697-B1/B2 now key the
boundary on the PREDICATE's verdict with `warn` asserted true at every length —
asserting `warn === false` at limit+1 was itself finding 2.

* docs(#3697): describe the third voice and the dash rule

Follow-on to the review-findings commit: that commit corrected the docs' claim
about the soft voice but left two things the code now does undescribed.

- There are THREE voices, not two. The over-cap voice ("could not be checked
  ... unverified") arrived with the fix for the review's CLAIM 2 and had no
  entry.
- Dash spellings require a full ID on both sides, and `..` / `…` / the word
  operators do not. That asymmetry is deliberate and load-bearing —
  `PREFIX-<digits><dash><digits>` is date- and sub-number-shaped — so a reader
  hitting `REQ-01-05` and getting silence has no way to find out why. The
  accepted cost (`REQ-01, REQ-02-05` unreported, bare `REQ-02-05` still
  reported) is stated rather than left to be discovered.

Documentation only; no behaviour change.

* fix(#3697): close the continuation review's findings

A continuation of the same adversarial reviewer, run against the reworked
round, refuted 6 of 7 claims. Four were real defects in this round's own work
and are fixed here; the other two are answered rather than changed, below.

1. THE SKIPPED-TEXT CLAUSE WAS ON ONE VOICE, NOT BOTH (refuted CLAIM A).
   The previous commit's message said both voices gained it. Only the soft
   return appended it. The assertive voice now carries it too — and, because
   that voice already names range tokens and inert residue under its own
   clauses, the note is filtered to what those did not already name. A warning
   that says the same token twice is one readers learn to skim.

2. THE CLAUSE'S WORDING WAS FALSE (also CLAIM A).
   It read "brackets and parentheses are not stripped". Square brackets ARE
   stripped by the selector — `[REQ-01, REQ-02]` is the documented form — so
   only parentheses qualify. Corrected in the message and in docs/CLI-TOOLS.md,
   which had inherited the same error.

3. THE OVER-CAP RULE STILL SILENCED A LINE (refuted CLAIM B).
   `oversizedTokens` filtered on `includes('-')`, which misses an over-cap
   OPERATOR: `REQ-01 <2049 dots> REQ-05` warned before this round, R2 declined
   to classify it once capped, and nothing reported it. That is the exact
   regression the field was added to close, one input over. Any token past the
   cap now counts — what it contains is irrelevant when we could not read it.

4. AND THEN OVER-REPORTED ONE (review MISSED finding).
   With (3) in place, a 2049-character CANONICAL REQ-ID was selected by the
   uncapped, fully-anchored selector AND flagged "REQ-ID selection on this line
   is unverified" — a contradiction inside one warning. A token the selector
   took was examined end to end, so it is excluded.

Two findings are answered, not changed:

  CLAIM C — the selector's own `REQ_ID_SHAPE_RE.test` is uncapped. True, and
  deliberate: this round does not touch what gets MARKED, and the pattern is
  anchored at both ends with no nested quantifier, so it is linear. The claim
  that "all predicate paths are capped" was too broad; the DETECTOR's are.

  CLAIM E — `REQ-01, REQ-02<dash>05` is silent for every dash. That is the
  documented, deliberate cost of holding dashes to the strict shape, and it is
  symmetric with ASCII, which behaved that way before this PR. The reviewer is
  right that "without losing a range spelling that should be detected" was too
  strong; a bare `REQ-02<dash>05` still warns.

Tests: #3697-9g (clause on the assertive voice, no repetition, bracket claim
true), #3697-9h (over-cap operator does not silence the line), #3697-9i (a
selected over-cap ID is never called unverified). #3697-9f is rebuilt — its
first version used the SAME id twice, so R2 could not have fired even uncapped
and it proved nothing; it now uses endpoints with a gap and fails when the
neighbour cap is removed.

Reversion control: all four fixes fail a named test when reverted in isolation
(#3697-9h, #3697-9i, #3697-9g, #3697-9f).

* fix(#3697): scope the over-cap exemption to what could actually pair

A second continuation of the same reviewer, against the reworked round,
confirmed the two claims that matter most and refuted three. This closes the
one real defect; the other two are answered below.

CLAIM J / CLAIM K (one defect, found from both directions). The previous
commit exempted EVERY selector-accepted token from `oversizedTokens`, on the
reasoning that the selector is uncapped and anchored so it examined the whole
token. True of that token's SELECTION — and not the same as "no rule was
suppressed by it". Two over-cap valid IDs either side of `..` are both
selected, so both were exempted, and R2 is capped: a line that warned before
this round went silent.

That is the third appearance of one class in this round — the cap suppresses a
check, and the suppression is not reported. Each fix for it over-corrected in
the opposite direction, which is why the rule is now stated in terms of what
was actually suppressed rather than in terms of the token: an over-cap token is
exempt only when it was selected AND nothing beside it could have paired with
it into a range (no range operator, no glued fragment, no second over-cap
token). Everything else is unexaminable and says so.

Two findings are answered, not changed:

  CLAIM M — the reviewer demonstrated, with driven evidence, a contextual rule
  that catches `REQ-01, REQ-02-05` while leaving `FY-2026-08` and `API-2-01`
  silent: recognise `PREFIX-a<dash>b` only when another SELECTED id on the line
  shares that prefix. That refutes this round's claim that the strict-dash
  trade was FORCED, and the claim is withdrawn — it is a design choice. The
  choice stands for this PR: the conservative rule is what ASCII already did
  before #3697, adopting a new contextual heuristic unreviewed at the end of a
  round is how the last three defects in this round were made, and #3697 asks
  for a warning rather than better range inference. Named here so the
  alternative is on the record rather than lost.

  Docs MISSED — CLI-TOOLS said every token over 2,048 characters "is not
  classified at all" and warns. Selection is not bounded; only range detection
  is. Corrected.

Confirmed by the same pass, and worth recording because they are the PR's
load-bearing promises: a 20,000-input comparison of the pre-extraction selector
against HEAD found `mismatches=0` (nothing about which REQ-IDs are MARKED has
changed), and the uncapped selector regex was measured linear from 100k to 800k
characters.

Tests: #3697-9f now asserts the range case is reported rather than silent, and
#3697-9j pins the exemption's scope in both directions. Reversion control:
restoring the blanket exemption fails both.

* fix(#3697): warn on zero selection, as the acceptance criterion asks

`Deferred`, `N/A`, `Pending`, `TBA` and `-` selected no REQ-IDs and stayed
SILENT, while three shipped artifacts said they warned: `docs/CLI-TOOLS.md`,
the `placeholderLed` census comment, and the advice string the command emits
to the user. The asymmetry was the tell — `Deferred (see ADR-7)` warned,
because the citation supplied the ID-shaped residue R3 required, while bare
`Deferred` did not. The claim was written into three places and never
executed once.

This is also #3697's AC-1b/AC-4 verbatim: "warn when `citedReqIds.length ===
0` while the raw capture is non-empty and not `TBD`".

R3b keys on the SELECTION being empty, never on what the prose means, so it
adds no free-text heuristic. It is deliberately not gated on ID-shaped
residue the way R3 is, and the negative space is what settles that: all
fifteen #2334/#2339 fixtures are held silent by non-zero selection or by
`placeholderLed`, and not one of them by the ID-shape gate — measured, not
argued. The gate was buying no negative space while costing the acceptance
criterion.

`tokens.length > 0` keeps an empty line and a comment-only line silent: the
tokenizer strips `<!-- ... -->` before splitting, so the shipped template's
own comment cannot reach the rule.

Selection behavior is unchanged. This warns; it never invents an ID.

Also extracts `warn` to a named const (round 3 review Minor 3) — this commit
adds a disjunct to exactly that predicate, and in the return literal a later
reordering would be a TDZ ReferenceError rather than a reader-visible error.

Tests: #3697-14 (six zero-selection lines warn and tick nothing, and the
warning names the TBD/None escape), #3697-14b (five placeholder spellings
stay whole-channel silent), #3697-14c (comment-only line stays silent).
Fail-first controls: all six #3697-14 cases fail against the pre-fix tree;
-14b and -14c pass at both ends, which is correct — they pin silence the
widening must preserve.

* fix(#3697): name the REQ-ID a glued delimiter dropped

`RANGE-01; RANGE-02` selects only RANGE-02 and marks only RANGE-02, with
`requirements_updated: true` — #3697's own half-success failure mode, reached
by one wrong delimiter, and silent before this rule. It is the issue's AC-1a
("a warning whenever the line contains ID-shaped content that the tokenizer
did NOT select") at the shape most likely to be typed by accident.

Round 4 review rated this Major rather than Blocker on the ground that the
case is indistinguishable from a parenthesised citation, since `(ADR-7)` also
shaves down to a bare ID. At the RAW token level it is distinguishable, and
that is what makes the rule shippable: `REQ-01;` is shaved of a trailing
DELIMITER, `ADR-7)` of a citation wrapper. R4 keys on that shave class and
requires the token to sit outside any parenthetical.

Measured before implementing: 0 false positives and 0 false negatives across
21 probes, including all fifteen #2334/#2339 negative-space fixtures. A first
cut without the parenthetical test scored 3 false positives — every one of
them a colon inside a citation (`(see ADR-7: section 3)`) — which is why that
test is the rule's boundary rather than an optimisation.

Adds the delimiter census the module did not have. The range-operator domain
was already censused; the comma-substitute domain was not. Swept 26
spellings: exactly two produce a silent under-selection, `; ` and `: `. Every
other spelling either selects both IDs or selects none and already warns. The
review hand-listed the semicolon; the colon is the sibling that sweep found,
and it fails identically.

`rangeReadingOnly` now excludes an R4 hit — the ambiguous voice claims nothing
was dropped, and must not speak for a line where something demonstrably was.

Tests: #3697-15 (four delimiter shapes warn, name EVERY dropped ID, and tick
exactly the unchanged selection), #3697-15b (three citation forms stay
whole-channel silent). Fail-first control: all four #3697-15 cases fail
against the previous commit's tree; -15b passes at both ends, pinning the
boundary the widening must not cross.

* fix(#3697): give the Requirements-line warning a stable machine kind

The warning's kind existed only in the prose of its message, so every consumer
and every test had to regex an English sentence — and rewording a message
silently un-asserted the tests that pinned it. Round 4 review Major 3.

The repo already had the settled seam for exactly these semantics.
`CONTEXT.md` records `diffLiveConfig` emitting `kind:'unverified'` for a
truncated scan, which is precisely this module's third voice; and
`WAVE_CLEANUP_WARNING` in `src/worktree-safety.cts` carries codes for the same
reason. ADR-3473 Decision 3 ("failure is a value") points the same way.

`formatRequirementsLineWarning` now returns `{ code, message }` instead of a
bare string, which also settles round 4 Nit 3 — `null` still means CLEAN, a
legitimate value, but the success arm is no longer a naked string one field
away from the shape the ADR standardises on.

The kind is carried ALONGSIDE the prose, never instead of it. `warnings[]` is
a documented `string[]` in `phase complete`'s JSON output, rendered by
execute-phase.md's "If has_warnings is true" step, so re-typing its elements
would be a breaking output-contract change for a shipped command. The code is
emitted as its own additive `requirements_line_warning` field, absent
entirely when the line is clean.

Vocabulary, exported so tests key on it rather than on string literals:
`req-line-misparse`, `req-line-range-reading`, `req-line-unverified`.

Tests: channel ROUTING in #3697-9/-9b/-9c/-9d/-9e/-9g/-10 now asserts the code;
message-content assertions stay where the user-visible wording is itself under
test. #3697-16 pins the code end-to-end through the CLI's JSON for four line
shapes and asserts warnings[] is still a string[]; #3697-16b pins that a clean
line emits no kind at all, because a field present on every run carries no
information. #3697-P4 holds kind-and-message-appear-together and
kind-is-in-the-declared-vocabulary over arbitrary input, so a channel added
later cannot ship without one.

* test(#3697): pin the divergence against the second parser of the same line

CLAUDE.md, KNOWN DEFECTS & ANTI-PATTERNS: "Generative Fix Divergence: when
sharing constants/arrays/parsers between parallel surfaces, add a parity
assertion test that fails if they diverge." Round 4 review Major 2.

`normalizePhaseReqIds` (src/gap-checker.cts) parses the SAME ROADMAP
`**Requirements:**` value — its own docblock says callers "may pass the
roadmap value through verbatim" — and diverges on four axes. Measured, not
inferred:

  line                                    phase complete      gap-checker
  RANGE-01..RANGE-05                      []                  5 IDs
  None (per ADR-7)                        []                  ["ADR-7"]
  (REQ-02)                                []                  ["REQ-02"]
  REQ-01a                                 []                  ["REQ-01a"]
  REQ-01, REQ-02                          both                both

This pins the divergence rather than removing it, which is the review's
second option and the correct one here: unifying the two would change what
`phase complete` MARKS, and "the ledger-writing set is byte-identical to base"
is the one invariant this PR holds fixed. Every axis is now asserted in BOTH
directions, so drift on either side fails here instead of widening silently.

The range axis is a DELIBERATE disagreement and is labelled as such — #3697
declines range expansion in terms ("I am not asking for range syntax to be
supported") while gap analysis adopted it under #1269.

The placeholder axis is the one worth reading twice: `None (per ADR-7)` is a
declared-empty line to `phase complete`, which reads the lead token, and a
one-requirement line to gap-checker, which strips parentheses first so the
citation survives its ID-shape filter. That is a citation being reported as a
requirement.

#3697-17b states the cost concretely: one line, five requirements in scope to
gap analysis and zero to phase complete. This PR is what makes that
contradiction visible, by finally giving the silent side a voice.

* fix(#3697): stop the skipped-text rider reporting a date, and close the 4b channel gap

Two round 4 review minors, both about a warning saying something it cannot
support.

MINOR 2 — false rider content. `REQ_ID_SUBSTRING_RE` is unanchored, so
`FY-2026-08` matches as `FY-2026` and lands in `unselectedIdShaped`.
`REQ_RANGE_TOKEN_RE`'s entire strict-dash arm exists to keep that shape
silent, and #3697-4 pins `RANGE-01 (target FY-2026-08)` as producing no
warning at all — but whenever some OTHER rule fired on a line that also
carried a date annotation, the rider told the author to "check whether any of
it is a requirement" about a date. Not a false warning, since the line was
warning anyway; false CONTENT, in the #2334 voice, through the side door.

Filtered at the MESSAGE rather than in the analysis: `unselectedIdShaped`
stays a faithful record of what the selector skipped — it is documented as a
fact that never routes — while the user-facing clause declines to assert
requirement-ness about a shape the design already ruled unadjudicable.
#3697-18b is the other half, so the filter cannot become a silencer: a
genuinely dropped REQ-ID is still named.

MINOR 1 — `#3697-4b` asserted only that the ASSERTIVE channel stayed silent,
so a regression routing `RANGE-01, TORANGE-05` into the AMBIGUOUS channel
would have passed. Whole-channel silence is not available on that fixture (the
pre-existing ghost-ID warning legitimately fires on the unregistered
`TORANGE-05`), so the precise assertion is that no Requirements-line warning
of ANY kind was emitted. The machine code added earlier in this round is what
makes that statable; before it, "both channels" could only have meant a second
prose regex.

* docs(#3697): record the Requirements-line seam in CONTEXT.md

CLAUDE.md names the CONTEXT.md glossary as a PR gate, and
`get_cochange_context(src/phase.cts, 45d)` ranks CONTEXT.md 4th at 25
co-changes — above src/init.cts and src/roadmap.cts. This PR introduced a
named seam, three warning kinds, a bound, a rule taxonomy and a deliberate
cross-parser divergence, and recorded none of it. Round 4 review Major 4.

The precedent is explicit rather than inferred: the directly analogous seam
is already there as `LIVE-CONFIG.GUARD.SEAM.truncation`, including its bound
and its boundary obligation — and that entry is the one this module's third
voice was modelled on.

Eight predicates, in the machine-oriented section beside it:

  .module                    the two exported functions and the code vocabulary
  .selector-identity         citedReqIds is byte-identical to base and is the
                             only thing reaching the ledger — a change to what
                             phase.complete MARKS is outside this contract
  .rules                     R1 / R2 / R2' / R3 / R3b / R4 / over-cap
  .kinds                     the three codes, and why they ride beside
                             warnings[] rather than inside it
  .cap                       2048, neighbours included, and the boundary rule
  .placeholder               the gate that actually holds the negative space
  .census-domains            both open domains with their NOT-reached members
  .gap-checker-divergence    the four axes, pinned not unified

The changeset type is `Fixed`, which exempts this PR from the docs/
co-change requirement — but the glossary gate is separate from that
exemption, and the 2048 cap in particular is a machine-canon-shaped fact
that until now existed only inside a source comment.

`docs/CONTEXT-INDEX.json` regenerated (269 predicates); lint:generated-sync
confirms all six targets in sync.

* docs(#3697): document what the command now does, in one changeset sentence

DOCS. The grammar section predated this round's two new rules, so it
under-described the behaviour it exists to make lookup-able:

- The placeholder paragraph enumerated three words; the rule is a DEFAULT.
  Any wording that selects no REQ-IDs warns, and the placeholders are matched
  as the LEAD token, so `None (per ADR-7)` and `**None**` are declared-empty
  too. The comment-only line is called out, because "any other wording" would
  otherwise read as covering the shipped template's own `<!-- ... -->`.
- The comma rule was implicit. `REQ-01; REQ-02` marks only REQ-02, and it is
  the quietest way to lose a requirement on this line — `requirements_updated`
  reads `true` either way — so it gets its own paragraph, with the
  parenthetical exemption stated beside it.
- The machine kind is documented where a consumer would look for it, with the
  instruction to key on the kind rather than the wording.
- The skipped-text note no longer implies it reports date shapes; it
  deliberately does not, and silently omitting that left the doc promising the
  behaviour this round removed.

CHANGESET (round 4 review Minor 4). CONTRIBUTING.md's format is
`**<Bold user-visible change>** — <symptom-led explanation>.` and both
canonical examples are one sentence; this fragment ran three. Now one, and
covering what the round actually delivers rather than only the range shape it
started from.

* test(#3697): keep phase.test.cjs off the docs-guard exemption fingerprint

A comment added earlier in this round named `docs/CLI-TOOLS.md` by path. The
docs-guard exemption ratchet (#3753 FIX 3) fingerprints literal `docs/`
references in exempt test files and fails when a new one appears, so that
comment turned four green gates red — `ci-docs-guard-registry` and the
registration lint — for a file that reads no documentation at all.

Caught by diffing the full suite's failing-name set against the same suite run
at `upstream/next` in a probe worktree: 33 of 37 failures reproduce at base
(install / config-home / shadowing tests under the sandbox HOME), and exactly
these 4 did not.

Rephrased rather than baselined. Adding the path to
DOCS_GUARD_EXEMPT_DOCS_PATHS is the sanctioned response when a test genuinely
starts READING a new docs path — the violation text asks the author to
re-confirm the exemption still holds. Nothing here reads documentation; the
guard matched prose. Baselining would have recorded a coupling that does not
exist and made the next reader wonder what phase.test.cjs does with
CLI-TOOLS.md. The comment still names where the contract is written, just
without planting a path string.

* fix(#3697): close four defects this round's own pre-push review drove

An adversarial cross-AI review of this round, run before the push, returned 6
CONFIRMED and 4 REFUTED. Every refutation was driven against the built tree,
and every one was a shape the author had not probed — the rules were correct
across the probe set and wrong just outside it.

(1) R4 FALSE POSITIVE, and it is the #2334 over-warning class arriving through
the rule added to close a different hole. `REQ-01, see ADR-7: section 3` fired:
`ADR-7:` is the same shave class as `REQ-01;`, and the parenthetical test does
not reach a BARE citation. The FP probe that scored this rule 0/0 only ever
tested the parenthesised form.

Fixed by requiring the dropped id's prefix to agree with a SELECTED id — the
module's own idiom, not a new heuristic: `reqEndpointsImplyInterior` already
demands an agreeing prefix for the same reason. Cost, stated in the census: a
dropped id whose prefix is on no selected id (`REQ-01, FOO-02: x`) stays
silent. Same trade the strict-dash rule takes — under-report a rare shape
rather than over-report a common one. Pinned as a declared blind spot by

(2) R4 FALSE NEGATIVE, on the DOCUMENTED form. `[REQ-01; REQ-02]` dropped
REQ-01 silently: the selector strips square brackets and R4's raw scanner did
not. The bracket spelling the shipped template recommends was the one shape the
rule could not see.

(3) The rider filter suppressed a REGISTERED requirement. `API-2-01` is a legal
requirement id — gap-checker's `parseRequirements` accepts it from
REQUIREMENTS.md — so a `\d+-\d+` filter hid a genuinely dropped requirement
behind a rule meant only to hide dates. Narrowed to a four-digit year segment.
The earlier #3697-18 case asserting `API-2-01` should be suppressed is REMOVED,
and the removal is recorded in place: its premise was refuted, it was not
inconvenient.

(4) An INVISIBLE line warned. A lone U+200B carried a token to the parser while
reading as empty to the author, so R3b fired with nothing on screen to explain
it. Zero-width and format characters are now stripped — stripped rather than
treated as delimiters, because splitting on one would fabricate two fragments
out of one ID.

Also corrects the documentation the same review found overstated: the line is
split on commas AND whitespace, and the ID shape is matched case-insensitively,
so `REQ-01 REQ-02` and `req-01, req-02` both select and neither warns. That was
pre-existing selector behaviour; this round is the one that asserted the docs
were true of it.

Tests: #3697-19 (four invisible-only shapes), -19b (embedded zero-width is
stripped, not split on), -19c (three citation forms), -19d (both bracket
spellings), -19e (both halves of the rider boundary), -19f (the declared blind
spot), -19g (the two documented tolerances). 500 tests in phase.test.cjs, 0
failures; lint:ci clean.

* fix(#3697): generalise the drop rule, and stop the invisible fix hiding a drop

The pre-push review's continuation refuted six of seven follow-up claims. The
first one is the one that mattered: the invisible-character fix committed in
c7dce173a INTRODUCED #3697's own defect. Stripping zero-width characters from
the detector wholesale made `REQ-01<ZWSP>, REQ-02` go SILENT — the selector
really does drop REQ-01, and the strip removed the only evidence of it. The
test written alongside asserted the tokens and the empty R4 result and never
asserted `warn`, so it DOCUMENTED the bug rather than catching it; that
omission was the reviewer's own MISSED finding.

An invisible is two different questions about one character, and the fix is to
stop conflating them: absence-of-content for the empty test, DECORATION on a
token for the drop rule. Neither is a reason to delete it from the line.

R4 is generalised accordingly, because the continuation drove four more shapes
a trailing-delimiter-only regex could not see — `REQ-01 ;REQ-02`,
`REQ-01 :REQ-02`, `**REQ-01;** REQ-02`, the backticked form — plus
`**REQ-01**, REQ-02`, where emphasis alone defeats the selector. These are one
class: decoration on a token the selector then cannot take. One rule, not four
patches; patching them individually is how a list stays short and wrong.

PARENTHESES ARE NOT DECORATION, and the suite caught me learning that: shaving
them made `REQ-01, (REQ-02), REQ-03 — REQ-05` report a glued delimiter that was
never there and broke #3697-9d's channel routing with it. A parenthesis is this
rule's citation marker.

The rider stops adjudicating an undecidable shape. `API-2-01` is a legal
requirement id and `API-2026-08` is too, while `FY-26-08` and `FY-2026-08-15`
are dates — no regex separates them, and both filters this round tried scored a
miss in each direction. It now NAMES the token and states the ambiguity, which
is the same thing the two warning voices already do about a range separator.
Filtering hides a real dropped requirement; reporting it bare asks the author
whether a date is a requirement; saying "this may equally be a date" does
neither.

The census and the docs are corrected to what the code does, including the part
that is NOT complete: the prefix gate does not stop a citation that SHARES a
selected prefix (`ADR-01, see ADR-7: sec 3` fires), and nothing at token level
separates that from a real drop. A prose heuristic on "see" is the free-text
detector this module exists to avoid, so the honest move is to say so.

CLAIM 17 — the invariant that actually matters — came back CONFIRMED on a
20,000-run fast-check property over arbitrary Unicode: `citedReqIds` is
identical to upstream/next's for every input, and marking is untouched.

513 tests in phase.test.cjs, 0 failures; lint:ci clean.

* fix(#3697): gate the drop rule on evidence, and stop an unmatched paren swallowing the line

Third pass of the round's own pre-push review, scoped to regression-hunting
rather than further polish. Three findings, all driven, all mine.

R4 OVER-WARNED on markdown styling. `REQ-01, see **REQ-7** for context` claimed
a dropped requirement: the previous cut treated any shaved decoration as
evidence, and emphasis is not evidence. Nothing separates that line from
`**REQ-01**, REQ-02` meaning to list one, so the rule now requires a positive
signal — a glued `;`/`:` (a list separator was INTENDED) or an invisible (the
token is CORRUPTED; nobody types one on purpose). Emphasis alone falls back to
the skipped-text rider, which names the id without asserting a drop, exactly as
`(REQ-02)` is handled. That is the #2334 class caught one cut before shipping.

R4 UNDER-WARNED on `**REQ-01**; REQ-02` — one shave pass cannot reach a wrapper
sitting behind a delimiter. Shaves to a stable point now.

The range OPERATOR lost its invisibles handling. `REQ-01 <ZWSP>..<ZWSP> REQ-05`
went silent, because the previous commit removed the invisible strip from BOTH
the tokenizer and R4 when only R4's was wrong. An invisible is two questions
about one character: for the classification rules it is noise and is stripped
from the token; for the drop rule it is the evidence and must survive on the
raw line. Stripping in both places hid a dropped id; stripping in neither hid a
range. The reviewer's MISSED finding named the missing control — regression
tests covered invisibles inside ids and not beside operators — and #3697-19i is
that control.

UNBALANCED PARENTHESES swallowed the line. `REQ-01, (note REQ-02; REQ-03`
reported nothing: a running-depth counter left the unclosed `(` open through
end-of-line, so every genuine drop after it inherited citation immunity. A
parenthesis confers that immunity only as part of a MATCHED span now — an
unmatched one is a typo, not a citation.

CLAIM 22 re-confirmed on a fresh 20,000-run property over arbitrary Unicode:
`citedReqIds` identical to upstream/next, marking untouched, warnings appended.

522 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite carries zero
head-only failures against a probe worktree at upstream/next.

* fix(#3697): make delimiter ADJACENCY the rule, and delete matched citations outright

Fourth and final pass of the round's own pre-push review. Three findings, and
they shared one root cause, so this is a narrower rule rather than a longer list
of shapes.

TOKEN-WIDE PAREN IMMUNITY LEAKED. `REQ-01, REQ-02;(note) REQ-03` is a single
whitespace token, so a matched parenthetical inside it conferred immunity on the
`REQ-02;` sitting OUTSIDE the parens, and the drop went silent. Matched spans
are now deleted from the line outright — which states what is actually meant,
that for this rule a citation is not on the line — and an UNMATCHED paren is a
typo that confers nothing. That also retires the running-depth counter whose
previous bug was the mirror image: an unclosed `(` swallowing the rest of the
line.

DECORATION WAS TESTED TOKEN-WIDE, so `REQ-01, see **REQ-7**; next topic` was
reported as a dropped requirement. It is a citation with sentence punctuation.
The rule is now ADJACENCY: styling is stripped, then the `;`/`:` must be
touching the id. `REQ-01;`, `;REQ-02` and `**REQ-01;**` qualify;
`**REQ-01**;` does not, because outside the styling that character is
punctuation. An invisible needs no adjacency test — nobody types one on
purpose, so anywhere in the token it is corruption rather than intent.

`**REQ-01**; REQ-02` therefore goes silent, and the test row asserting
otherwise is inverted rather than deleted quietly: it was added one commit ago
on the reasoning this pass refuted, and nothing distinguishes it from
`see **REQ-7**; next topic`.

Worth recording plainly: three successive cuts of this rule fired on a
citation, and each fix was a narrower definition of EVIDENCE, never a longer
list of shapes. The list-lengthening instinct is what produced the bug each
time.

The review's last MISSED finding named the missing control — the paren tests
all surrounded matched spans with whitespace, so none covered a span sharing a
token with an id outside it. #3697-19j carries both directions now.

526 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite zero
head-only failures against a probe at upstream/next; the invariant that
`citedReqIds` is identical to upstream re-confirmed on 20,000 arbitrary
Unicode inputs.

* fix(#3697): state R4's real boundary, and stop the over-cap voice masking a drop

Two defects, both found by this round's own pre-publication body claim-audit.

1. A DEMONSTRATED drop was discarded by the unverified voice. On
   `REQ-01, REQ-02: <2049 chars>` the analyzer names REQ-02 in
   delimiterDroppedIds and the formatter then reported `req-line-unverified`,
   whose message never mentions it — the one actionable finding masked by the
   token beside it. The over-cap channel now excludes a line carrying an R4
   hit, exactly as rangeReadingOnly already did and for the same reason: that
   voice's whole claim is that nothing could be checked, and R4 has already
   checked something. The assertive channel still carries the over-cap rider,
   so nothing about the cap is traded away. Pinned by #3697-19l, which fails
   against the pre-fix build and nothing else does.

2. Three shipped artifacts asserted behaviour the code does not have — the
   same class as this PR's round-4 blocker, re-committed. CONTEXT.md's rules
   predicate, the CLI tools reference, and the warning's own advice string all
   listed markdown emphasis as an R4 trigger. It is not: styling is shaved
   BEFORE the test and tolerated around an id, never a trigger on its own, so
   `**REQ-01**, REQ-02` and `**REQ-01**; REQ-02` are both silent. The trigger
   is exactly a glued `;`/`:` or an embedded invisible.

   The census predicate was wrong in a second way. Its 26-spelling separator
   sweep found only `;` and `:` because the sweep was SYMMETRIC-ONLY and
   therefore biased: one-sided attachment drops silently for every punctuation
   outside the set — `/ | & + . > \` and the full-width and non-ASCII forms
   `; , ؛` all measured silent. The domain is wide open and R4 covers two
   characters of it. Said plainly in all three places rather than widened
   here: every previous widening of this rule first fired on a citation, so it
   is not done blind at the end of a round.

Both blind spots are now PINNED as tests (#3697-19m styling-only, #3697-19n
one-sided separators) so the documents and the code cannot drift apart again —
which is what the round-4 blocker asked for.

tests/phase.test.cjs: 542 tests, 542 pass, 0 fail, 0 skip. lint:ci rc=0.
Both CONTEXT-INDEX consumers regenerated.

* fix(#3697): re-sweep the separator census properly, and say what it really found

The round-4 census in src/phase.cts concluded "exactly two — `; ` and `: `"
from a 26-spelling sweep. That conclusion was forced by how the sweep was
built, not by the code: it swept the ONE-SIDED form (`REQ-01; REQ-02`) for the
semicolon and colon, and only the BARE and SYMMETRIC forms (`|`, ` | `) for
every other separator. Different members of the domain were tested in
different shapes, so no other answer was reachable. Caught by this round's
pre-publication claim-audit of the response comment, reading the census
comment against its own swept list.

Re-swept fully crossed and driven through the built artifact: 21 separators x
{bare, trailing-space, leading-space, both-spaces} = 84 combinations. 26 select
both ids, 24 under-select and already warn, and 34 UNDER-SELECT SILENTLY. All
34 are one shape — a separator glued to exactly one of the two ids, e.g.
`REQ-01/ REQ-02` or `REQ-01 /REQ-02` — for every punctuation except `,` and
the `;`/`:` that R4 covers.

So R4 covers TWO CHARACTERS of a wide-open domain. That is now what the census
comment, the CONTEXT.md census-domains predicate and the CLI tools reference
all say. The set is deliberately not widened here: three successive cuts of
this rule fired on a citation, and a fourth at the end of a round with no
adversarial pass is how each of those got in.

Second false passage in the same block: styling-only decoration was described
as "left to the skipped-text rider, which names the id". A rider only exists
inside a message, and a message only exists once some rule sets `warn` — so on
a line where nothing else fires, `REQ-01, **REQ-02**` is wholly silent.
Describing it as handled reads as coverage. #3697-19m already pins the silence.

so the test matches the documented claim.

tests/phase.test.cjs: 552 tests, 552 pass, 0 fail, 0 skip. lint:ci rc=0.
Both CONTEXT-INDEX consumers regenerated.

* chore(#3697): regenerate both CONTEXT-INDEX.json after rebasing onto next

Rebased onto next @ f4fefb0be. The two generated indexes conflicted on the
replay and were resolved by regenerating, not by hand-merging:
`npm run gen:context-index` for docs/CONTEXT-INDEX.json and
`node examples/dynamic-context-management/gen-context-index.cjs --write` for
the example's copy. Against next, each now differs only in the eight
PHASE.REQ-LINE.SEAM.* predicates this PR adds (plus the PHASE class and the
count); every base-side change (the SEAM.* predicates, the ADR-3942 value
rewrites) is carried. `lint-example-parser-parity` and
`gen-context-index --check` both pass.

* fix(#3697): an over-cap token outranks the ambiguous range voice

Round 7 review, Minor 1. `rangeReadingOnly`'s guard conjunction checked
`hasGluedRangeFragment`, `inertIdShaped` and `delimiterDroppedIds` but not
`oversizedTokens`, so a line carrying a clean, fully-selected spaced range
*and* an unrelated token past the 2048-char scan cap was coded
`req-line-range-reading` — a code CONTEXT.md's PHASE.REQ-LINE.SEAM.kinds
predicate documents as "nothing was dropped" — over a token no rule (R1-R4
all skip over-cap tokens) had ever examined. Since the PR tells machine
consumers to branch on `.code` rather than parse prose, that is a false
"nothing to verify further" signal.

The review's suggested fix was to add `oversizedTokens.length === 0` to the
conjunction. That clause is right and is here, but on its own it routes the
line to the ASSERTIVE channel: `req-line-misparse`, whose message says the
line "could not be parsed as a comma-separated REQ-ID list" on a line where
every ID present was in fact selected. That is the #2334 over-warning class
this module's own channel-selection docblock exists to prevent — a false-clean
code traded for a false-assertion one. So the correct destination is
`req-line-unverified`: the line was not CHECKED, which is not the same as
clean, and nothing on it demonstrably failed to parse either.

Both non-assertive voices were carrying their own inline copy of the same
"nothing was demonstrably dropped" conjunction, and that duplication is what
let them drift: `rangeReadingOnly` omitted the cap, while the over-cap channel
excluded a spaced range wholesale via `!hasSpacedRange`. Extract it once as
`nothingDemonstrablyDropped` and have both read it. The new predicate is a
strict superset of the old `!hasSpacedRange` guard — `spacedRangePairs.every()`
is vacuously true when no spaced range fired — so the over-cap channel's
behaviour on every line without a spaced range is unchanged, and R2 firing on
an endpoint the selector did not take still routes to the assertive channel.

Exactly one input class changes routing: a clean fully-selected spaced range
beside an unexamined over-cap token, which moves from `req-line-range-reading`
to `req-line-unverified`. Pinned by `#3697-19n` (the twin of `#3697-19l` on
the other side of the boundary — there a demonstrated drop outranks the
unverified voice, here the cap outranks the ambiguous one), with `#3697-19o`
as the negative control asserting a clean range with nothing over the cap is
still a range reading.

* docs(#3697): state the warning-code precedence, and what the cap condition actually is

Two surfaces, one point. The round 7 finding cited CONTEXT.md's
PHASE.REQ-LINE.SEAM.kinds predicate as the documentation of what
`req-line-range-reading` claims, and it was right to: that predicate said "R2
alone fired on selected endpoints; nothing was dropped" with no mention of the
scan cap, describing a line the code could not distinguish from one carrying a
token it never examined.

The range reading is the weakest of the three claims and yields to the other
two: a demonstrated drop makes the line a misparse, and a token the cap left
unclassified makes it unverified. `docs/CLI-TOOLS.md` gains that sentence; the
CONTEXT.md predicate gains it plus two precision points that this round's own
pre-push adversarial review extracted over three passes, each with a driven
counterexample I reproduced before acting on it:

  * "nothing was dropped" overstates the rule. The discriminator is RULE-scoped
    by design (round 3, Major 3), so that a parenthesised ID-shaped token does
    not re-open the #2334 over-warning class — `(REQ-02)` is indistinguishable
    from `(ADR-7)` at token level and is carried by the skipped-text rider, never
    by this code. `REQ-01, (REQ-02), REQ-03 - REQ-05` selects three, names REQ-02
    as skipped, and is still a range reading. The predicate now says "no rule
    named a dropped ID", which is what the code tests.

  * The deferral condition is `oversizedTokens` being non-empty, NOT the presence
    of a token past the cap. Those differ: a long token the selector itself took
    can be exempt, because selection is uncapped and anchored and such a token
    was therefore examined. `RANGE-01 - RANGE-05, R-<2047 sevens>` yields
    `oversizedTokens=[]` and stays a range reading. Two earlier attempts to
    characterise WHEN the exemption applies were both refuted — the neighbour
    test admits any non-short neighbour, not just a range operator — so the
    predicate now states the condition and defers the exemption's own rule to
    SEAM.cap rather than paraphrasing it a third time.

Verified after the edit: deferral holds if and only if the cap left a token
unclassified, across all three counterexamples plus controls, and an exempt
selector-taken long token is exhibited. No behaviour change — predicate text,
one CLI-reference paragraph, and the two regenerated indexes. Predicate count
unchanged at 285 across 22 classes, 0 duplicate ids; lint-example-parser-parity
and both `--check` generators pass.

* test(#3697): rename the round 7 regression pair — 19n was already taken

Self-found immediately after the push, before anything was published to the
review thread. The two tests added this round were named `#3697-19n` and
`#3697-19o`, and `#3697-19n` was already in use: it is the declared-blind-spot
case for one-sided separators in both attachment directions, generated inside a
loop with a computed label, which is why a grep for a literal `test('#3697-19n'`
did not find it. The PR body's own *Declared blind spots* list already refers to
`#3697-19n` with that meaning.

Nothing failed. Duplicate test names do not error, and the suite stayed green at
567/567 — which is the argument for fixing it rather than against. Two concrete
costs: any TAP name-set differential collapses same-named tests under `sort -u`,
so one of the two becomes invisible to exactly the did-not-run and pass->fail
checks that name-set comparison exists to perform; and a reviewer reading
"#3697-19n" in the body now gets a different test than the one the body means.

Renamed to `#3697-19p` (over-cap beside a clean range) and `#3697-19q` (its
negative control), the next free ids in the series; the pre-existing `#3697-19n`
is untouched at its original 4 occurrences. Cross-references inside the renamed
block were updated with them. Negative control re-run under the new ids: 19p
still fails against pre-fix source and passes after, 19q passes at both ends.

900504f985 fix(#3776): decide nothing-to-commit from the staged diff, not from staging success (#3859)
* fix(#3776): decide nothing-to-commit from the staged diff, not from staging success

`cmdCommit`'s empty-diff guard tested `stagedPaths.length === 0`, but
`stagedPaths` records paths whose `git add` exited 0 — "did staging
succeed", not "is there anything to commit". Staging an already-committed,
unmodified file succeeds while contributing no diff, so the guard was
reachable only when every named path was missing from disk.

The ordinary empty-diff case therefore fell through to `git commit`, where
the only thing converting the failure back to `nothing_to_commit` was a
string match on git's output. Git runs the pre-commit hook before it
decides there is nothing to commit, so a rejecting hook pre-empted that
match and the caller was handed `commit_failed` carrying a gate message
about a commit that had nothing to gate.

Ask git whether the staged paths actually differ instead. Two conjuncts
are load-bearing: the `length === 0` short-circuit keeps the
all-missing-paths case exact (a pathspec-less `diff --cached` would test
the whole index, so unrelated staged work would suppress the guard), and
`!isMergeInProgress` keeps a merge from being abandoned — during a merge
git refuses a partial commit, so the pathspec describes nothing about what
would land.

Nine regression cases in tests/commands.test.cjs cover the brief's six
acceptance criteria plus the merge interaction. Against the pre-fix build
exactly one fails; the other eight pin behaviour that was already correct.

Residual sibling of #2608/#2693, which covered `git add` failing; this
covers `git add` succeeding and contributing nothing.

* fix(#3776): exempt a cherry-pick too, but never a revert

The empty-diff guard must not decide from a pathspec git will not honour.
That test was merge-only; git refuses a partial commit during a cherry-pick
for the same reason, so the guard would have fired there and reported a
silent `nothing_to_commit` where the pre-fix code surfaced git's refusal.

The three sequencer states do not agree, so this is driven rather than
reasoned by analogy (git 2.54):

  MERGE_HEAD        fatal: cannot do a partial commit during a merge.
  CHERRY_PICK_HEAD  fatal: cannot do a partial commit during a cherry-pick.
  REVERT_HEAD       permitted; behaves like an ordinary commit.

REVERT_HEAD is therefore deliberately excluded: enumerating it alongside the
other two — the obvious move — would suppress this fix during a revert and
reintroduce the very misreport it removes. Both new states are pinned by a
test, and the revert arm fails against the pre-fix build exactly as AC1 does.

`canScope` keeps its narrower merge-only test on purpose; widening it would
change pre-existing cherry-pick behaviour, which is outside this fix.

* fix(#3776): probe the working tree, not the index

`git commit -- <paths>` is a PARTIAL commit: it records the working-tree
content of those paths and ignores what is staged. The guard was probing
`git diff --cached` — the index — which answers a different question than
the commit asks.

Driven on the same path, in this order: `git add` an unmodified file, then
write to it, then probe.

  git diff --cached --quiet -- p   rc 0   ("nothing staged")
  git diff --quiet HEAD -- p       rc 1   ("the tree differs")
  git commit -m m -- p             committed the new content

So a working-tree write landing between the `git add` above and the probe —
another process in a shared checkout, which this project explicitly supports
— would let the guard report `nothing_to_commit` for a call that would have
recorded that content. Probing `HEAD` asks the question the commit answers.

Not reachable through this function single-threaded, because the staging
loop re-adds every named path immediately beforehand, so index and working
tree agree at the probe. The change is correctness by construction rather
than a fix for an observed miscommit.

An unborn HEAD makes `diff HEAD` fatal; that falls through to the commit as
any other probe error does, and is now pinned by a test — the first commit
in a repo must not be swallowed by an empty-diff guard.

Both added probes are now gated on the guard being able to fire at all, so
an unscoped commit and an `--amend` pay for neither.

Found by adversarial pre-filing review; the index/worktree distinction was
not something my own path-shape probes could have surfaced.

* test(#3776): pin the assume-unchanged boundary; correct a stale comment

`git update-index --assume-unchanged` makes `git add` stage nothing and makes
BOTH diff forms — `--cached` and `HEAD` — report no difference, so no
diff-based guard can see a change to such a path. `git commit -- <path>` is
the odd one out: it reads the working tree directly and records it.

So a modified assume-unchanged path now reports `nothing_to_commit` where it
previously committed. That is the answer consistent with this function's own
staging step, which honoured the flag one loop earlier — but it is a
behaviour change, and it belongs on the record as a decision rather than
surfacing later as a surprise.

Also corrects an AC3 comment still describing the `diff --cached` whole-index
form that the previous commit replaced.

* chore(#3776): set changeset fragment pr to 3859

The fragment carries the PR's own number, which is unknowable before the PR
exists. Backfilled post-create; the repo's changeset lint rejects the `pr: 0`
placeholder.

* fix(#3776): do not read an unanswered sequencer probe as "no merge"

`execGit` surfaces a spawn timeout as `exitCode: 1` (`_spawnResult`:
`result.status ?? 1`) — the same code `rev-parse --verify` returns for a ref
that does not exist. So the MERGE_HEAD and CHERRY_PICK_HEAD probes could not
tell "not in that state" from "never answered", and the empty-diff guard read
both as "not in that state". That is the one path in #3776 that did not fail
toward the previous behaviour: a timeout during a real merge decided
`nothing_to_commit` from a pathspec git will not honour and left the merge
unconcluded, where before it was a loud `commit_failed`.

Treat an unanswered probe as "assume the partial commit would be refused" —
which falls through to `git commit` and lets git speak for itself.

Routed into `partialCommitRefused` only, deliberately never into
`isMergeInProgress`. That flag also feeds the pre-existing `canScope`, and
widening it there is worse than the misreport it fixes: with `canScope` false
the commit runs bare, and a bare commit during a merge is PERMITTED — git
concludes the merge with the whole index under a message naming one file.
Driven: the whole-flag form reports `committed` where this form reports
`commit_failed`, and it drops the pathspec on the ordinary timeout, re-opening
the #2112 scope leak.

* fix(#3776): pin the empty-diff probe against diff-only configuration

`git diff` is porcelain and honours settings `git commit -- <paths>` does not,
so an unpinned probe let a caller's configuration decide whether the guard
fires. Driven against git 2.54, each with the paired `git commit -- <path>`
confirmed to record the change the unpinned probe reported as absent:

  diff.ignoreSubmodules=all      a gitlink bump is invisible to the probe
  .gitmodules  ignore = all      the same, and it needs NO local config at
                                 all — it is checked in, so it arrives with
                                 a clone
  diff=<driver> + textconv       two different blobs converge to one text,
                                 so the probe sees no change; no submodule
                                 involved

`--ignore-submodules=dirty` rather than `=none`, because `dirty` is what a
partial commit of a submodule path actually means: it records the gitlink,
which moves only when the submodule's HEAD does. Under `=none` a merely dirty
submodule work tree reports a difference the commit would not record, sending
an empty call back to `git commit` — the same misreport, re-entered from the
other side. `dirty` still overrides both `diff.ignoreSubmodules` and a
checked-in `.gitmodules` `ignore`, so the gitlink vectors stay closed.

`--no-ext-diff` is deliberately absent: `--quiet` short-circuits ahead of an
external diff driver, so `diff.<driver>.command` cannot invert the probe
(driven: rc 1 with and without the flag).

* docs(#3776): disclose the two outcome changes the changeset omitted

The body listed what stays unchanged and never named the arms whose
user-visible outcome moves, so neither would have reached the changelog:

  - a modified path under `git update-index --assume-unchanged` now reports
    `nothing_to_commit` where it was previously committed. `git add` already
    honoured the flag one loop earlier; the guard reports what staging did.
    Documented in a code comment and pinned by a test since the first round,
    but absent from the fragment.
  - naming a submodule whose work tree is dirty while its recorded commit has
    not moved now reports `nothing_to_commit` rather than `commit_failed`,
    because nothing would have landed. New in this round, from the
    `--ignore-submodules=dirty` pin.

* test(#3776): use helpers.cleanup() for the submodule fixture teardown

`local/no-raw-rmsync-in-tests` rejects a bare `fs.rmSync` in a test: the
helper carries the Windows-EBUSY retry budget (`maxRetries`/`retryDelay`)
that a raw call does not, and a submodule work tree is exactly the shape
that holds handles open on Windows.

Caught by CI, not locally — the round ran the two affected suites but not
`npm run lint:ci`, so the repo's own rule never fired until the push. The
chain now exits 0 locally against this tree.

* fix(#3776): never drop a named assume-unchanged path

`--assume-unchanged` is the one state where `git diff` and
`git commit -- <paths>` genuinely disagree: `git add` stages nothing,
both diff forms report no difference, and `git commit -- <path>` still
reads the working tree and records it. The empty-diff guard therefore
reported `nothing_to_commit` about content the caller named in `--files`
and git would have written.

commit is made — so suppressing its misreport must not be paid for by a
silent drop. Same rule the timeout routing already follows: a fix for a
misreport may not cost content.

The guard now asks `git commit --dry-run --porcelain` whether the commit
would record anything, and stands aside on rc 0. That is the same
decision the real commit makes, so there is no second implementation of
it to drift. It does not run the `pre-commit` hook (driven: a rejecting
one neither fires nor writes a marker), which is what matters — a firing
`pre-commit` is the whole of #3776. It is NOT hook-free in general: git
2.54 fires `post-index-change` here, so a repo using that hook sees it
once for the probe and once for the commit. Stated rather than claimed
away.

Asking git rather than reconstructing its answer was reached by
measurement. Comparing `git hash-object` against `HEAD:<path>` was tried
and is wrong three ways, each a silent drop of named content: it misses a
mode-only change (`chmod +x` leaves the blob identical while the commit
records `100755`); it cannot hash a submodule path at all (`fatal: Unable
to hash sub`, while the commit advances the gitlink); and the path it
needs must be parsed out of `ls-files` output, which `core.quotePath`
renders as `"caf\303\251.md"` by default. Each has its own arm, and the
non-ASCII arm pins `core.quotePath` so it cannot go vacuous.

Falling through on the `ls-files` tag alone — without asking whether
anything would land — is also wrong: an UNMODIFIED assume-unchanged path
would reach `git commit`, which with any unrelated modified file present
prints `no changes added to commit`, a string the fallback does not
match, and returns `commit_failed`. That is #3776 re-entered from the
other side, the same shape `--ignore-submodules=none` would have
re-entered it. Pinned by its own arm.

The `ls-files` read is an optimisation, not a gate: it keeps the dry run
off the hot path when no assume-unchanged entry is present, and when it
cannot answer the dry run simply runs, because the dry run needs nothing
from it. Failing closed there would drop content and failing open would
re-enter #3776 — both are wrong answers to a question that can be asked
directly.

`--skip-worktree` is not a second instance. A present, modified one exits
1 from `git add` and fails closed as `staging_failed` above the guard; an
absent one is skipped before `git add` runs (#2014) and is answered by
the `stagedPaths.length === 0` arm, exactly as it was pre-fix. Both
shapes pinned, because the shorter claim ("never reaches the guard") is
too strong.

* test(#3776): register fixture teardown so a failed assertion cannot leak

`bumpedSubmodule()` creates its sub-repo as a SIBLING of `tmpDir`, and
the unborn-HEAD arm creates `fresh` outside it too, so the describe's
`afterEach(() => cleanup(tmpDir))` reaches neither. Both were cleaned by
a trailing statement in the test body, which any failing assertion above
it skips — leaking a git repo into the temp root.

`bumpedSubmodule()` now records the path and a describe-scoped
`afterEach` drains it, which covers all three of its callers at once;
the unborn-HEAD arm takes `t.after`, the form already used elsewhere in
this file.

Negative-controlled both ways with a deliberate assertion failure
injected into the dirty-submodule arm, under an overridden TMPDIR:
before, one `*-sub` repo survives the run; after, none.

* fix(#3776): never read an unanswered dry-run probe as "nothing to record"

The `git commit --dry-run --porcelain` probe that decides the assume-unchanged
boundary is the one probe in the guard whose rc 0 is the reassuring answer, so
it inverts the diff probe's safety: `execGit` collapses a spawn timeout (or any
spawn error) to `exitCode: 1`, byte-identical to git's own "nothing to record",
and the guard then reported `nothing_to_commit` about content named in
`--files` that git was never asked to write. Same conflation the sequencer
probes already defend against.

Only a CONFIRMED rc 1 with no spawn error closes the path now; a timeout, a
spawn error, or rc 128 falls toward the real commit, where git speaks for
itself. Five arms in tests/commit-files-pathspec.test.cjs pin it (posix +
windows timeout shapes, rc 128, the ls-files optimisation's own timeout, and a
negative control on an unmodified path); the injection helper gains an optional
`matchArg` so the dry run can be targeted without intercepting the real commit.

Also corrects the comment that claimed both sequencer probes are gated on
`guardApplies` — the MERGE_HEAD probe predates this fix and is unconditional.

* fix(#3776): probe with --no-verify so a hook-firing git cannot close the guard

Round 4, review finding 3 (Minor). The `git commit --dry-run --porcelain`
probe's safety rested on an empirical claim about one git version: that
`--dry-run` does not run `pre-commit`. git 2.54 satisfies it, but the failure a
differing version would produce is silent and lands in exactly #3776's own
configuration.

A `pre-commit` that fires and rejects exits 1 — the same code git returns for
"nothing to record" — so the closure would read it as a CONFIRMED empty answer,
drop the content the caller named in `--files`, and report `nothing_to_commit`.
That is #3776 re-entered through the probe the fix added.

`--no-verify` forecloses it structurally rather than documenting the version
dependency. Driven on git 2.54: rc-identical in both directions (rc 0
would-record, rc 1 nothing) with and without the flag, so it is behaviour-
neutral where the version already agrees.

Two claims deliberately NOT widened: `--no-verify` does not suppress
`post-index-change`, which still fires on this call with or without it (driven
both ways); and the real `git commit` is untouched — #3776 is a bug about a
hook's message reaching the caller wrongly, never a licence to skip hooks.

The new arm pins the FLAG rather than an outcome, because the outcome it
protects is unobservable on a git that already declines to run the hook. It is
a seam assertion over the argv the guard actually issued, not a source grep.

* test(#3776): pin all-missing --files during a merge or cherry-pick

Round 4, review finding 1 (Major) and finding 7 (Nit, its coverage half). The
review asks for the `stagedPaths.length === 0` disjunct to be gated on
`!partialCommitRefused`, or for the combination to be documented and tested.
Documented and tested — the gating is refused, with cause.

The premise is confirmed: the state is reachable exactly as described, and
during a merge the `nothing_to_commit` report does not tell the caller the merge
is still open. The prescription is not. With every named path missing,
`stagedPaths` is empty, so `canScope` is false and the fall-through reaches a
BARE `git commit`, which git PERMITS during a merge and which then CONCLUDES it.

Driven, git 2.54, through cmdCommit with the prescription applied:

  cmdCommit(cwd, 'add the thing', ['.planning/never-produced.md'])
  -> { "committed": true, "hash": "8e6bf45", "reason": "committed" }
     MERGE_HEAD gone; HEAD is a 2-parent merge commit recording
     .planning/shared.md with the caller's resolution content.

So the gating trades a report that writes nothing for one that silently writes
the whole index under a message naming a path that does not exist, and reports
success. That is the same trade the timeout routing already refuses one block
up, which is why the sequencer states gate the DIFF branch only.

The behaviour is also pre-existing and unchanged by this PR: at 86452da7 the
identical short-circuit sat ABOVE the MERGE_HEAD probe, so it never consulted
the sequencer either. The residual — a merge held open behind a
`nothing_to_commit` report — is offered as a separate issue alongside the three
already deferred, not folded into this fix.

These are behaviour pins, not regression tests: they pass at base and red on the
gated implementation (both arms, verified).

* docs(#3776): state the git-version provenance once, not at three claims

Round 4, review finding 6 (Nit). The guard carries ~159 comment lines around 32
lines of executable logic, and the review's specific complaint is that "driven
against git 2.54" is repeated near-verbatim in three places, which makes the
decision tree harder to scan.

Hoists the provenance to a single block header and reduces the three repeats to
the observation each actually carries. One claim keeps its version explicitly
and now says why: the `--no-verify` reasoning is version-SENSITIVE rather than
merely version-observed, so it is the one place the version is load-bearing
instead of incidental.

The behavioural matrix stays inline rather than moving to an ADR or a doc block.
Every claim in it is a constraint on the four flags immediately below it, and the
value of having it here is that the next reader who wants to "simplify" one of
those flags meets the driven counter-example in the same screen. Splitting the
constraint from the code it constrains is how the flags get dropped.

Comments only. No behaviour change; suite and lint:ci unchanged.

* docs(#3776): correct two driven figures in the new guard commentary

Both found by this round's own pre-push adversarial review, and both re-driven
before adopting.

1. The empty-paths rationale said a bare commit during a merge produces a
   "three-parent commit". It produces a TWO-parent merge commit. Three was the
   token count of `git rev-list --parents -n1 HEAD` (commit + two parents) read
   as a parent count. `git cat-file -p HEAD | grep -c '^parent '` returns 2.
   This round's commit message for the pins already said two, so the tree
   contradicted itself.

2. The `post-index-change` disclosure said a repo using that hook "sees it once
   for the probe and once for the commit". Driven with a counting hook: git
   fires it TWICE per `git commit --dry-run`, and twice again for the real
   commit — 2/2/2 across the flagged probe, the unflagged probe and the real
   commit. The disclosure understated the cost by half in both halves.

Comments only. No behaviour change; suite 351/351 and lint:ci unchanged.

80d2236ca5 fix(#4112): drop redundant $(( subshell wrapping in pause-work.md Context Detection (#4140)
* test(#4112): add failing-first regression coverage for pause-work.md Context Detection

Extracts and executes the shipped Context Detection bash block to prove the
$(( arithmetic-context misparse (SC1102/SC1106/SC2205) as a hard syntax
error, plus boundary/independence coverage for the phase/spike/sketch/
deliberation resolution the fix must preserve.

* test(#4112): fix false-green regression test — assert dash/sh failure, not bash -n

The prior version asserted bash -n syntax validity and wrapped bash -c
execution, neither of which detects this bug: bash/zsh silently fall back to
a working command-substitution reading of the ambiguous $(( construct, and
bash -n never evaluates arithmetic-context content at parse time. A gsd-test
run against the still-broken file passed 41594/41594 with this test in
place — a false green. POSIX sh/dash does not implement that fallback and
throws a real "Syntax error: Missing '))'", which is what this version
asserts against.

* fix(#4112): remove leaked tool-call tags corrupting the regression test file

A subagent's Write introduced trailing </content>/</invoke> markup at the
end of tests/pause-work-context-detection.test.cjs. gsd-test's own
tests/portability-rule-disable-ban.test.cjs (which parses every test file)
correctly caught this as a parse error. Strips the garbage lines; no
behavioral change.

* fix(#4112): drop redundant $(( subshell wrapping in pause-work.md Context Detection

phase=/spike=/sketch= opened with $((, which POSIX sh/dash parses as
arithmetic expansion and rejects (Syntax error: Missing '))') since the
enclosed text isn't valid arithmetic. bash/zsh silently retry it as command
substitution, which masked the defect there. Dropping the inner grouping
parens (matching the deliberation= line already in the same block) makes
the construct valid under bash, zsh, and dash alike, with identical
fallback-to-empty-string behavior when nothing matches.

Once the surrounding syntax parses, ShellCheck can now also analyze the
inner ls -lt calls it previously couldn't see past the parse failure,
newly surfacing the same pre-existing SC2012 ("use find instead of ls")
suggestion already baselined for the file's other ls usage. Baseline
updated to reflect the true current count; no ls-vs-find behavior change
made, as that is a separate, pre-existing, out-of-scope question.

* fix(#4112): verify shell discrimination instead of trusting the binary name

Code review finding: falling back from dash to sh could silently produce a
non-discriminating test on a host where /bin/sh is bash-compatible (e.g.
macOS) — such a shell never throws on the broken construct either, so the
test would pass whether the bug were present or not. resolvePosixShell now
verifies the candidate actually rejects a known-ambiguous $(( snippet
before using it, and skips with an explicit reason when none does. The
gsd-test Linux bench (dash as /bin/sh) is unaffected either way.

* fix(#4112): route regression test through process-seam, splitLines, cleanup

npm run lint:ci flagged 7 violations gsd-test's node:test run doesn't check:
local/no-adhoc-markdown-parsing (single fence-spanning regex),
local/no-crlf-fragile-split (bare \n split), local/no-unbounded-spawn (x4,
hand-rolled execFileSync with no timeout), and local/no-raw-rmsync-in-tests.
Rewrites the test to route every subprocess call through
tests/helpers/process-seam.cjs's runHook() (bounded by construction),
tests/helpers.cjs's cleanup() for temp-dir removal, and a line-by-line fence
scan using the text-lines.cts splitLines() seam, matching this repo's
established extraction idiom (tests/no-hardcoded-home-gsd-tools.test.cjs).
No behavioral change to what is asserted.

* fix(#4113): add no-op to empty then-body in chunked-planning-mode.md's outline resume-check

The `### 8.5.1 Outline Phase` resume-detection `if` block only contained a
comment in its `then` clause, which is a syntax error under both bash and
zsh if executed literally. The workflow ShellCheck lint added by #4109
already flags this (SC1009/1048/1072/1073/2105) but the findings were
masked by matching entries in the pre-existing-findings baseline; those
five entries are removed here so a regression re-surfaces as a new
failure instead of being silently re-absorbed.

Removing the 5 stale baseline entries for chunked-planning-mode.md in the

(SC2105) in a different fenced block of the same file: a bare `continue`
outside any bash loop in the ### 8.5.2 per-plan resume-check. Same root
cause class as the original bug (pseudocode fenced as literal bash) —
fixed the same way, with a `:` no-op preserving the documentation.

cad70f4f3e fix(#4120): replace shellcheck npm dep with dependency-free downloader (#4121)
* fix(#4120): replace shellcheck npm dep with dependency-free downloader

The `shellcheck` devDependency (added in #4109) pulled in decompress@4.2.1
for archive extraction, which carries an unpatched CRITICAL zip-slip
vulnerability (GHSA-mp2f-45pm-3cg9, CVSS 9.1) plus two moderate findings.
decompress's latest published version IS the vulnerable one -- no patched
release exists upstream, so npm audit fix cannot resolve this by upgrading.

Removes the shellcheck package entirely and replaces its role with
scripts/lib/shellcheck-fetch.cjs: a small downloader using only Node's
built-in https/zlib plus a hand-written tar-entry reader, fetching a pinned
koalaman/shellcheck release directly from GitHub releases. The reader never
uses an archive-supplied name as a filesystem path (the exact defect class
decompress had) -- it only returns the matched entry's bytes; the caller
writes those bytes to a path it constructs itself. Bounds the download with
a 30s-per-hop timeout, consistent with the ShellCheck subprocess's own
timeout. Covers linux/darwin on x86_64/aarch64, matching this repo's actual
CI (lint-tests runs only on ubuntu-latest) and local dev needs; Windows
fails with a clear, honest error rather than silently misbehaving.

Adds tests/lint-workflow-shellcheck-fetch.test.cjs covering the tar-parser
(unit cases plus a fast-check property test per CLAUDE.md's parser-testing
requirement), a security behavioral pin confirming traversal-style entry
names are treated as opaque strings never filesystem paths, and boundary
coverage for the redirect-following logic's MAX_REDIRECTS limit
(limit-1/limit/limit+1, via an injectable transport, no real network I/O).

npm audit: 0 vulnerabilities (was 1 critical + 5 moderate). The lint script
reproduces the identical result against the current tree:
"212 pre-existing finding(s) from baseline, 0 new" -- no behavior
regression, no baseline changes needed.

* fix(#4120): register shellcheck-fetch.cjs with the installer

scripts/lib/shellcheck-fetch.cjs shipped without being added to
GSD_SCRIPTS_LIB_FILES in bin/install.js, which would have left it orphaned
on uninstall and broken the golden install-tree fixtures for every runtime.
Adds the entry and regenerates the 19 affected fixtures via
npm run gen:install-tree.

8c9265d4e5 fix(#3724): warning-only Dimension 3b findings no longer force the revision loop (#3758)
* fix(#3724): stop advisory Dimension 3b findings from forcing the revision loop

Dimension 3b (undeclared/temporal coupling, #1954) is spec'd "never a
blocker" but tagged severity: warning — the tier plan-phase's revision
loop counts as must-fix — and the planner is never taught the rule, so
every multi-wave phase touching shared mutable state replans at least
once, and intentionally coupled plans re-flag identically every
iteration to the stall prompt.

Three coordinated changes:
- gsd-plan-checker: retag 3b to severity: info, the tier
  references/revision-loop.md already exempts by design; recognize a
  coupling_justified frontmatter declaration in the Do-NOT-flag list so
  deliberate pairs converge. Additions are offset by trimming 3b
  motivation prose — the checker sits 45 bytes under its LARGE hard cap.
- plan-phase step 12: INFO-only accept — an issues block with zero
  BLOCKER/WARNING entries accepts the plan and surfaces the advisories
  instead of re-entering the revision loop. Real blockers and warnings
  still gate unconditionally.
- gsd-planner: slim pointer in assign_waves to the new
  progressive-disclosure reference gsd-core/references/planner-coupling.md
  (the planner sits 19 chars under its own cap), which carries the
  shared-mutable-state rule and the coupling_justified escape hatch so
  first-pass plans avoid the finding when the coupling is unintentional.

Documented the coupling_justified field in docs/reference/plan-md.md.
Growth acks per #2914; inventory manifest and install-tree fixtures
regenerated for the new reference file.

Closes #3724

Claude-Session: https://claude.ai/code/session_01GshUzpGjoxiw6uNRiFMHvM

* test(#3724): pin Dimension 3b at severity: info

The severity retag makes the old assertion (severity: warning) stale;
lock the advisory tier from both directions — info must be present,
warning must not — so a future edit cannot silently re-arm the
revision-loop trigger.

  describe pins the other three criteria: plan-phase's INFO-only accept
  clause (proven failing-first), the BLOCKER + WARNING count staying
  intact, the coupling_justified Do-NOT-flag exemption + fix_hint, and
  the planner pointer + planner-coupling.md content.

  pin note carried forward into the gsd-planner.md entry, updated for

* fix(#3724): review round 2 — align the stance enumeration, complete the template contract

MAJOR: <adversarial_stance>'s severity enumeration gains the INFO bullet so it
agrees with Dimension 3b's 'ALWAYS INFO' mandate instead of contradicting it.
Funded by extracting the inline <examples> block to the new progressive-
disclosure reference gsd-core/references/plan-checker-examples.md (@-inlined
from the same spot; #1949 precedent), which also restores the 3b motivation
clause round 1 traded away (Nit 4) and nets the agent file SMALLER than base
(49107 -> 48486) — the extraction the byte pressure was owed.

MINOR: gsd-core/templates/phase-prompt.md now carries coupling_justified, and
the field's shape becomes one 'plan-id: reason' string per coupled peer so a
plan justified against two peers can express it; docs/reference/plan-md.md's
Type column names the shape.

NIT: the 3409 ack's plan-phase entry no longer calls the #1168 workflow
ratchet an 'XL tier'.

Acks and derived artifacts updated accordingly (checker entry removed — a
shrink needs no ack; INVENTORY roster row + regen:derived for the new file).

* test(#3724): derive the 3b negative severity assertion (review round 2)

Every severity token in the 3b span must BE the tier revision-loop.md exempts,
replacing the hardcoded severity:warning negative — if the loop's exemption
ever moves, the failure names the real conflict instead of blaming the agent
file with a mutually-unsatisfiable pair.

next moves — the deltas are the durable claims. The round-1 removal of

* fix(#3724): review round 4 — close the verify-work surface, harden the boundaries

BLOCKER: verify-work.md's verify_gap_plans is the second multi-plan
consumer of the checker's sentinels, and its ISSUES FOUND handler entered
revision_loop with zero severity parsing — the guaranteed replan #3724
fixed in plan-phase, alive on the gap-closure surface. The handler now
counts BLOCKER + WARNING and accepts INFO-only returns with advisories
displayed. The checker's INFO stance bullet is reworded to the claim that
is true everywhere ('revision gates count only BLOCKER + WARNING').

Minor 1: plan-phase's iteration_count >= 3 arm recounts severities, so an
INFO-only third check accepts instead of halting on a '0 issues remain'
user gate. Minor 2: the coupling_justified exemption now requires the
entry to NAME the other plan, closing the blanket-suppression reading.
Nit 1: INVENTORY row states the extraction buys cap headroom, not context.
Nit 2: the advisory display gains a concrete format on both surfaces.

Ack fragment re-anchored at base ddde001a: verify-work.md +264B (new
entry), plan-phase.md +395B, checker still net negative (-512B).

* test(#3724): pin the verify-work accept and the iteration-cap boundary (review round 4)

Two wiring assertions: verify_gap_plans' ISSUES FOUND handler gates on
BLOCKER + WARNING and accepts INFO-only blocks, and plan-phase's
iteration_count >= 3 arm recounts severities instead of gating advisories
— the limit+1 boundary of the gate this PR fixes.

Claude-Session: https://claude.ai/code/session_01GshUzpGjoxiw6uNRiFMHvM

* fix(#3724): review round 5 — fail closed at the gates, surface the advisory

Blocker 1: the checker's step-10 status rule routes an INFO-only result to
## ISSUES FOUND (with a new ### Advisories (info) template section and a
severity-aware recommendation) so the orchestrator receives the block and
displays the advisory instead of silently accepting a bare PASSED.

Blockers 2+3: all three gate surfaces (plan-phase step 12 both arms,
verify-work verify_gap_plans) carry one canonical clause verbatim — an entry
whose severity is missing or unrecognized counts as a BLOCKER (fail closed) —
making the accept condition an explicit-INFO whitelist while keeping
issue_count coherent for stall math.

Major 1: the INFO stance bullet scopes its claim to the plan-phase and
verify-work gates (quick mode's loop still revises on any ISSUES FOUND).
Major 2: INVENTORY row and ack $comment state the extraction's real trade
(readability, +0.6 KB eager runtime context), not a cap remedy.
Minor 1: plan-md.md marks coupling_justified as prompt convention, unvalidated.
Nit 1: ack absolutes re-anchored at base 1e67ec97; checker now +120B and acked.

Claude-Session: https://claude.ai/code/session_01GshUzpGjoxiw6uNRiFMHvM

* test(#3724): pin the round-5 contract — fail-closed parity, INFO-only return shape

New: three-surface verbatim parity test for the fail-closed clause (Blockers
2+3); checker return-contract test for the INFO-only ## ISSUES FOUND route and
advisories section (Blocker 1). All seven newly pinned tokens are absent at
f3a5682d, so each new assertion fails pre-fix.

Updated: accept-clause regexes track the explicit-INFO whitelist wording;
the severity sweep scopes to the span's fenced yaml examples via
yamlSeverityTiers (round-5 Minor 3, applied to the blocker negative too);
the iteration-cap comment states it is a prose pin, not an executed boundary
check (Minor 4); splitLines call sites document the line-pin coupling (Nit 2).

* fix(#3724): adopt next's line wrap in the 3b motivation clause — drops a wrap-only hunk from the diff

Byte-identical content; the wrap difference was an artifact of the round-1
base adaptation predating upstream's #3003 landing.

Claude-Session: https://claude.ai/code/session_01GshUzpGjoxiw6uNRiFMHvM

* fix(#3724): review round 7 — gate every checker consumer, not just the two audited ones

Blocker: quick/steps/plan-checker-loop.md (issue-named in #3724) gets the
same canonical fail-closed clause and explicit-INFO whitelist accept as
plan-phase/verify-work — an INFO-only result proceeds instead of entering
quick mode's revision loop.
Major: import.md plan_validate handles the checker return by severity
(INFO-only never blocks an import) and is added to agent-contracts.md's
consumer enumeration, which had omitted it.
The checker's INFO stance bullet drops the quick-mode carve-out — the claim
is universally true again now that every consuming gate is severity-aware.
Minor: an applied coupling_justified exemption is surfaced as its own info
advisory so a stale one-sided declaration stays observable.
Nit: plan-phase's revision-iteration Display line is explicitly conditioned
on not having already proceeded to step 13.

Claude-Session: https://claude.ai/code/session_01GshUzpGjoxiw6uNRiFMHvM
Emitted-Drift-Ack-Growth: import.md — #3724 round 7: the plan_validate step's checker-return handler becomes severity-aware — counts BLOCKER + WARNING failing closed and accepts an explicitly-INFO-only return with advisories displayed instead of blocking the import

* test(#3724): pin the round-7 surfaces — five-gate parity, quick/import accepts, exemption visibility

The verbatim fail-closed parity test extends to quick/steps/plan-checker-loop.md
and import.md plan_validate; new assertions pin quick mode's INFO-only proceed,
import's never-blocks accept, import.md's presence in agent-contracts.md's
consumer row, and the surfaced coupling_justified exemption advisory. All four
newly pinned token families are absent at the pre-fix head, so each new
assertion fails first.

e242d85c92 fix(#4109): rewrap unquoted DISPATCH_SLUGS-shaped consumption to survive zsh (#4116)
* test(#4109): add zsh regression coverage for gate-check and invoke_reviewers dispatch

Extends tests/review-plan-coverage-manifest.test.cjs to cover the two
DISPATCH_SLUGS consumption sites the existing #3301 coverage-check tests
don't reach: the write_reviews gate-check block (ALL_LANES_SKIPPED /
TOTAL_LANE_FAILURE counting) and invoke_reviewers' dispatch + join loops.
Both extract the real shipped bash from review.md and run it under bash and
zsh, same convention as the existing coverage-check rows. Expected RED under
zsh pre-fix, GREEN post-fix.

* fix(#4109): rewrap unquoted DISPATCH_SLUGS-shaped consumption to survive zsh

Bash word-splits an unquoted scalar on IFS by default; zsh does not (no
setopt SH_WORD_SPLIT anywhere in these files), so a scalar accumulated from
multiple space-separated tokens and then consumed via bare `for x in $VAR`
collapses onto one bogus iteration under zsh whenever it holds 2+ tokens.

Fixes all four review.md sites reported by #4108/#4109 (invoke_reviewers
dispatch + join loops, the gate-check block, and the #3301 coverage-check
block), plus the identical pattern found by a repo-wide sweep in
complete-milestone.md, code-review.md, pr-branch.md, sync-skills.md, and
execute-phase/steps/per-plan-worktree-gate.md. Each site is rewrapped in
unquoted command substitution (`$(printf '%s' "$VAR")`), which re-splits
identically under both shells regardless of SH_WORD_SPLIT — the same
mechanism that already made the accumulator-building loops in these files
shell-safe.

* test(#4109): warn loudly when the zsh probe fails instead of skipping silently

detectShells() drops the zsh test lane whenever a live zsh probe fails (e.g.
on a CI runner without zsh installed), and a dropped lane reads identically
to a passing one in the suite's own output — exactly the blind spot that let
#4109's bug class ship undetected. Both copies of this helper (this file and
its byte-identical duplicate in review-build-prompt-optional-sections.test.cjs)
now emit a greppable console.warn when the probe fails, so a run without zsh
reads as "zsh coverage unknown" rather than "all lanes green".

* ci(#4109): gate workflows/*.md's embedded bash blocks in lint:ci

Adds scripts/lint-workflow-shellcheck.cjs, wired into npm run lint:ci, so
this bug class can't land undetected a third time. Two independent checks
run over every ```bash block in gsd-core/workflows/**/*.md:

- ShellCheck (new `shellcheck` devDependency, downloads and caches the real
  koalaman/shellcheck binary) catches the general unquoted-expansion/
  word-splitting family in argument position. 212 pre-existing findings
  across the tree are absorbed into scripts/lint-workflow-shellcheck-baseline.json
  (matched on {file, code, message}, not line number, so unrelated edits
  elsewhere in a file can't spuriously un-baseline anything) — fixing all of
  them is out of scope for this issue; only NEW findings fail the build.
- A custom structural check specifically for #4109's own shape: ShellCheck
  does not flag a bare `for x in $VAR` word-list — it treats that as an
  intentional idiom under any ruleset (confirmed empirically). This check
  does, and gates the build on any occurrence, with zero tolerance (no
  baseline) since every known site was already swept and fixed on this
  branch.

* test(#4109): update pr-branch cherry-pick loop test anchor for the zsh fix

extractPickLoop()'s PICK_LOOP_MARKER located the create_pr_branch cherry-pick
loop by the literal substring "for HASH in $INCLUDED_COMMITS", which no
longer appears verbatim after this issue's fix rewrapped that loop in
unquoted command substitution. Updates the anchor (and its error message,
now derived from the same constant instead of duplicating stale text) to the
new literal form. No behavior change to the extraction logic itself.

Emitted-Drift-Ack-Growth: review.md — #4109's fix adds explanatory comments at 4 sites; net code is functionally equivalent, comment expansion grows the file
Emitted-Drift-Ack-Growth: complete-milestone.md — #4109's fix adds explanatory comments at 3 sites documenting the zsh word-splitting divergence
Emitted-Drift-Ack-Growth: code-review.md — #4109's fix adds an explanatory comment documenting the zsh word-splitting divergence
Emitted-Drift-Ack-Growth: pr-branch.md — #4109's fix adds explanatory comments at 3 sites (TRANSIENT_DIRS, INCLUDED_COMMITS, FILTER_PATHS)
Emitted-Drift-Ack-Growth: sync-skills.md — #4109's fix adds explanatory comments at 2 sites (CREATE_LIST/UPDATE_LIST, REMOVE_LIST)

* test(#4109): cover lint-workflow-shellcheck parsers + add timeout

Adds tests/lint-workflow-shellcheck.test.cjs covering the hand-rolled
parser/logic functions exported by scripts/lint-workflow-shellcheck.cjs
(stripCommandSubstitutions, stripShellComments, substitutePlaceholders,
extractForLoops, findBareForLoopSplits, findingKey, partitionAgainstBaseline)
that shipped with zero coverage — CLAUDE.md requires at least one fast-check
property test for parsers, included here (bare/braced forms always flagged
naming the variable; quoted/substituted/literal forms never are).

Also bounds runShellcheck's subprocess with a 60s timeout: the `shellcheck`
npm package's own API has no timeout option and internally blocks on a
synchronous spawnSync, so this reimplements the binary resolve/download step
via the package's own exported config/download and calls spawnSync directly
with a native timeout. And guards the CLI entry point with
`if (require.main === module)`, matching this repo's sibling dual-purpose
lint scripts — without it, requiring the module for its exported functions
(as the new test file does) also triggered a live ShellCheck run as a side
effect.

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.

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

* 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.

* 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

* 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).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* 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

* 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.

* 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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

git diff --stat:

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

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

Two reproduced consequences:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

This reverts commit 03c74a97c911e9ddc53675aded9c9bbb89f14cd1.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Test-only; revertable independently of the merge commit.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(#2761): narrow the state-update-progress pin claim to what mutation testing actually proved, add the test that covers the rest

Round-11 BLOCKER response gap (verified, not a guess): the changeset and
ADR-612 amendment point 2 both claimed the round-11 tests pin
`cmdStateUpdateProgress` so "a future change to the enumerator's default
cannot silently move ... what state update-progress reports without failing
a test." Mutation testing disproves this. Reverting BOTH the state.cts
explicit `phaseIdConvention` thread AND simulating the phase-locator.cts
pre-#612 hardcoded-null default (`phaseIdConvention: null` at that one call
site) leaves the existing PIN test ("writes a real percent for a
bracket-scoped milestone") green, because that percent comes from
`computeUpdateProgressPreview` -> `buildStateFrontmatter`, a separately and
already-correctly-threaded derivation the state.cts inline comment at ~:965
already candidly documents.

What the reverted thread DOES change, empirically, is `phaseDirs`/`totalPlans`
— the enumerated `.value` this call site feeds into the #3233 zero-plans
no-op gate a few lines below. That is the one place a regression at this call
site is observable in the command's output. Added a test that pins exactly
that: a bracket milestone whose declared phases carry no plans on disk,
alongside a decoy directory that plainly does not belong to the milestone
(no bracket tag, no phase token) but does have a plan. Correctly scoped, the
decoy is excluded and the #3233 no-op fires (`updated: false`). Degraded to
the pass-all legacy reading, the decoy is swept in, `totalPlans` flips
nonzero, and the no-op never fires (`updated: true`).

Mutation-tested against both scenarios:
- Reverting ONLY the state.cts explicit thread (falls back to `undefined`,
  which `getMilestonePhaseFilter` resolves via the identical
  `resolvePhaseIdConvention(cwd, undefined)` call the explicit thread also
  makes): new test stays green — confirms the single-hunk thread really is
  pure single-derivation hygiene, exactly as the existing inline comment
  claims, for this test too.
- Forcing `phaseIdConvention: null` at that call site (the combined-revert
  scenario the round-11 mutation testing actually exercised): new test FAILS
  (`updated: true, percent: 0` instead of the expected `updated: false`).
  Restoring the real code makes it pass again.

Narrowed the changeset and ADR-612 point 2 prose to match: `cmdMilestoneComplete`'s
enumerated set is pinned against a pass-all-degrade regression (genuine,
already verified in round 11); `cmdStateUpdateProgress`'s own call site is now
pinned against the #3233 zero-plans no-op specifically, not against the
reported percent, which the prose no longer claims. Added a one-line pointer
to the new test in the state.cts inline comment. No production behavior
changes — test and documentation only.

* docs(#2761): reconcile ADR PR-2 module map

* 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;

ef9ce3e598 fix(#3702): count asterisk, plus and ordered markers as deferred-items entries (#3739)
* fix(#3702): deferred-items counts `*`, `+` and ordered markers as list items

`deferred-items.md` has no template and no mandated shape, but its parser
recognised only the `- ` hyphen marker. Asterisk bullets, plus bullets and
dot-terminated ordered lists — all lists in CommonMark and GFM — contributed
ZERO entries on both the headless and the heading-delimited path, and a mixed
file dropped its non-hyphen entries while keeping their hyphenated siblings,
under-reporting without ever looking empty.

The restriction was a regex literal inherited from the Gaps seam, where the
template genuinely mandates the hyphen YAML-lite form; nothing in the module's
stated rationale distinguishes `*` from `-`.

Widened on the deferred path only:
- `splitGapsEntriesCore`'s entry opener, `extractGapEntryFields`' line-0 strip
  and `rawGapEntryText`'s line-0 strip take a `BulletMarkers` parameter that
  DEFAULTS to the hyphen-only set, so `## Gaps` keeps its template-mandated
  grammar byte-for-byte and the module still has exactly one grouping pass.
- `splitDeferredHeadingEntries`' body-bullet test, `stripLeadingBulletMarker`
  and `acknowledgeDeferredItem`'s status-field regexes move in lockstep —
  widening what OPENS an entry without widening what is STRIPPED before field
  extraction would surface an entry that can never resolve.

Unchanged, and pinned by tests: prose-only and bare headings still contribute
nothing ("prose is not an item"); a table under a leaf heading still yields
exactly its rows, since table lines are skipped before the body-marker flag can
be set and a `|` row is not a list marker; the paren-terminated ordered form
`1)` is out of this fix's scope.

* docs(#3702): changeset fragment (pr: 0 placeholder pre-create)

* fix(#3702): widen the forensic-audit prose entry rule to match the parser

Sibling site of the same defect class, found by a defect-class sweep of the
deferred-items consumers. `/gsd-progress` check 7 does NOT go through
`gsd-tools query` — it globs `deferred-items.md` and has the model read entries
by a prose rule that mandated "one entry per top-level `- ` line". Left as-is,
the marker widening would hold on the CLI path while the one consumer that
bypasses the parser kept reporting "No unresolved deferred items" for a file
written with `*`, `+` or an ordered marker: the same false negative, surviving
in the only place the fix could not reach by code.

Also pass DEFERRED_BULLET_MARKERS explicitly where the heading path extracts
fields. It was already correct — stripLeadingBulletMarker pre-strips the widened
set from every line, so the default hyphen strip is a no-op there — but relying
on that leaves a detection site and a strip site nominally on different marker
sets, which is exactly the asymmetry the BulletMarkers doc comment warns about.
Explicit is local; inferred is a trap for whoever edits the strip next.

Out of scope, noted rather than fixed: forensic-audit.md globs only
`.planning/phases/*/` and so misses archived milestone phases that
`scanDeferredItems` covers. Pre-existing, a different defect, and not this
issue's ruling.

* docs(#3702): note the milestone-close halt for heading-shape non-hyphen files in the changeset

A heading-delimited deferred-items.md written with */+/ordered markers
previously parsed to zero and closed silently; it now yields entries whose
heading shape acknowledgeDeferredItem refuses, halting complete-milestone
until hand-edited. User-visible, so the fragment states it.

* chore(#3702): set changeset fragment pr to 3739

* fix(#3702): CR-normalise the heading path and the acknowledge writer (review B1, M4, m2)

B1 — `splitDeferredHeadingEntries` stored RAW lines; on a CRLF file every
body line but the last still carried its `\r`, the `$`-anchored marker
strip failed on it, the marker survived into field extraction and the
field was lost — a `**Status:** resolved` that was not the file's final
line resurfaced its entry as open. The heading path now stores CR-stripped
lines like the headless path already did, and the strip regex tolerates a
trailing CR on its own. Round 1's CRLF test put `**Status:**` on the last
line, the one position `collectSection`'s `.trimEnd()` had already
de-CR'd; the new tests put it first and mid-body.

M4 (pre-existing on `next`) — `acknowledgeDeferredItem` found the status
line on a CR-stripped copy but rewrote the raw line with a `$`-anchored
`.*`, which cannot consume `\r`; `replace` returned its input, and the
writer reported `ok` over byte-identical content. The rewrite now runs on
a CR-stripped line. The comment that claimed `.*$` consumed the `\r` is
corrected — it was the bug, stated as the design.

m2 — the indent probe for an inserted `status:` line ran on the raw line
and fell back to indent 0 on CRLF; it is CR-stripped too.

* fix(#3702): derive every deferred-items marker regex from one source (review M3, N1, N2)

M3 — round 1 carried the marker alternation in FOUR places: the
`BulletMarkers` pair and two inline literals inside
`acknowledgeDeferredItem`, under a doc comment saying the interface
existed so a detection site and its strip site could not drift. All four
now derive from `DEFERRED_MARKER_ALT`; drift is impossible rather than
discouraged. A parity test pins the vocabulary against
`markdown-sectionizer`'s `iterateBullets` on everything the two grammars
are meant to agree on, and names the two points they deliberately differ.

N1 — the ordered marker is `\d{1,9}\.` (CommonMark §5.2), not `\d+\.`.

N2 — the marker is followed by `[ \t]`, not `\s`, which also accepted
`\r`; the tab remains accepted (CommonMark-legal) and the divergence from
`iterateBullets`' literal space is pinned rather than papered over.

The four regexes are exported for the parity test only.

* fix(#3702): an ordered marker opens an entry only from `1.` or inside a run (review B2, m1)

B2 — `\d+\.` alone read ordinary prose as a list: "2026. was a bad year
for this module" and, under `### Notes`, "3. is the number of retries we
settled on." both opened an entry on round 1, the second straight through
the "prose is not an item" contract that round's AC4 claimed to preserve.
CommonMark §5.3 faces the same ambiguity when an ordered list would
interrupt a paragraph and resolves it by requiring the list to start with
1; `matchListOpener` applies that rule wherever an ordered marker is seen,
with the run carried per list (headless) or per leaf-heading body. Numbers
after the first are ignored, as CommonMark ignores them. Stated cost,
pinned: a hand-numbered list starting at 2 reads as prose — every ordered
record in the #3702 scan starts at 1.

Both reviewer cases are pinned as prose; the ruling's `1. alpha / 2. beta`
shape still counts.

m1 — the 9-digit boundary is pinned at both sides (`999999999.` opens,
ten digits is not a marker), and the 3-vs-4-space indentation cliff is
pinned as deliberately NOT applied: the parser is indent-lenient because
surfacing a questionable hand-written entry beats dropping a real one.

* fix(#3702): thematic breaks close the list and fenced code never opens an entry (review M1, M2)

M1 — `- - -` was a phantom `"- -"` entry on base; widening the marker set
added `* * *` and `+ + +` to the class, and `* * *` is the separator an
author writing in the `*` style is most likely to use. A CommonMark §4.1
thematic break (plus the `+ + +` gesture, which is the same garbage as an
entry name) now closes the open entry on the headless path and is dropped
from the body on the heading path — neither an item nor a continuation.

M2 — neither splitter was fence-aware, so `+ `-prefixed diff lines and
`1.`-numbered repro steps inside a code block counted as entries; #3702's
wild records carry exactly those blocks. Both splitters now classify lines
by the sectionizer's own `scanFencedBlocks` (so `~~~`, indented and
unterminated fences behave as `stripFencedCode` would): fence content
never opens an entry, is continuation inside an open one — keeping the
span invariant `acknowledgeDeferredItem` re-verifies — and is discarded
before the first.

* test(#3702): range the #2287 deferred-items property over marker × shape × line ending (review B3)

The `#2287` property hard-coded `- ` and filtered `\r\n` out of its
arbitraries, so the widened marker set — an enumerated domain, exactly
what a property is for — was never under it. It now ranges over
`{-, *, +, ordered}` × `{headless, heading}` × `{LF, CRLF}`, with the
heading shape placing `**Status:**` first or last: the review's
prescription (markers × line endings) would not have reached B1, which
lives on the heading path only, so the shape axis is the load-bearing
addition. Ordered entries are numbered from 1, so the B2 run rule is
under the property too.

A second property drives `acknowledgeDeferredItem` over every unresolved
headless entry across the same marker × line-ending grid — the one that
reaches M4 (a CRLF rewrite that reported `ok` and wrote nothing) and m2.

* test(#3702): pin the milestone-close halt on a heading-delimited `*`/`+`/`1.` file (review m3)

A heading-delimited `deferred-items.md` written with a non-hyphen marker
previously parsed to zero entries and let `complete-milestone` close
silently; it now yields entries whose heading shape `acknowledgeDeferredItem`
refuses, which the milestone loop turns into `record_ack_failure` → exit 1.
The loop is prose in a workflow, so the test drives the two CLI calls it
makes: `audit-open --json` must list the entry, and
`audit-open acknowledge --text <the audit's own text>` must refuse with the
heading-delimited message and write nothing.

* docs(#3702): changeset and forensic-audit prose carry the round-2 grammar

The changeset names the CRLF fixes, the ordered start-at-1 rule, thematic
breaks and fences. The `/gsd-progress` forensic-audit step is the one
prose parser of this file and must state the same grammar the code has.

* fix(#3702): round-review refinements — run ends at a paragraph, rejected ordinals unstripped, breaks at any indent, fenced fields, `## Gaps` scope

Findings from the pre-push adversarial review of round 2, each pinned:

- An ordered run ENDS at a paragraph that follows a blank line (CommonMark
  §5.3); a non-indented line with no blank before it is lazy continuation
  and keeps the run open. `1. a` / blank / `paragraph` / blank / `5. x` is
  one entry, not two.
- The heading path strips the marker off every body line before field
  extraction (#3457); a line whose ordinal `matchListOpener` REJECTED must
  not be stripped, or "3. status: resolved" as prose loses its `3. ` and
  reads as a resolved field. `splitDeferredHeadingEntriesDetailed` now
  carries a per-line opener flag and only accepted openers are stripped —
  in headless regions of a heading-shaped file too.
- A thematic break is recognised at any indent, matching the parser's
  indent-lenient reading of items; `    * * *` was a phantom `* *`.
- Fenced lines carry no FIELDS either: a `status: resolved` quoted inside a
  code block no longer resolves its entry on either path.
- Block structure (breaks, fences) is a property of the GRAMMAR, carried as
  `BulletMarkers.blockStructure`: the deferred set opts in, the Gaps set
  does not, so `## Gaps` is byte-for-byte on its `next` behaviour — the
  round-2 M1/M2 change had reached it through the shared splitter.

* test(#3702): the property exercises the rejected-ordinal branch; the N2 control is independent

Round review: the widened #2287 property numbered every ordered run from 1
and so never generated an ordinal the start-at-1 rule rejects — it could
not tell round 1 from round 2 on B2. Each entry may now carry a decoy prose
line beginning with a non-1 ordinal, placed where it cannot end a run
(before the first headless entry; first in a heading body), followed by a
`status: resolved` that must never become a field; and a decoy-only
heading body must yield no entry.

The N2 assertion accepted a tab, which round 1's `\s` accepted too, so a
`[ \t]` → `\s` revert alone stayed green. NBSP, form-feed and vertical-tab
are now asserted refused — the assertion that fails on that revert on its
own, and the disclosure that `[ \t]` narrows what round 1 accepted.

* fix(#3702): the splitter records its own opener flags; an opener clears the blank-line memory

Round-review continuation, two state defects in the ordered-run logic:

- `blankSeen` survived the headless splitter's opener branch, so an opener
  followed by a lazy continuation line read as "paragraph after a blank" and
  ended the run — `1. a` / blank / `2. b` / lazy / `3. c` folded `c` into `b`.
  The opener branch now clears it.
- The heading path re-derived per-line opener flags for headless regions
  without the paragraph reset, re-accepting a rejected `3. status: resolved`
  under a stale run and stripping it into a field. `GapsEntrySpan` now
  carries the flags the splitter itself computed, and the heading path reads
  them; the re-derivation is deleted.

* fix(#3702): ordered-run memory is per indent — nested runs resolve, nested ordinals never inherit the top-level run

Round-review continuation 2: nested openers consulted the TOP-LEVEL run
flag and never wrote their own, so a nested `1. / 2.` run under a hyphen
entry rejected its `2. status: resolved` (round 1 resolved it), while a
nested `3. status: resolved` under a nested `- ` bullet inherited an open
top-level run and was stripped into a false field.

`OrderedRuns` keys the memory by indent: a new opener at indent d resets
every deeper level, a paragraph after a blank at indent d ends the runs at
d and deeper, a thematic break or a heading clears all. Both splitters use
it; the top level still decides entry boundaries, nested levels decide
only which continuation lines are accepted openers for field stripping.
Pinned for LF and CRLF.

* fix(#3702): run levels — one top level at or above the base, CommonMark column indents, a fence ends its level's runs

Round-review continuation 3:

- A dedenting top-level list (`    1.` / `  2.` / `3.`) lost its entry
  boundaries: the exact-indent run lookup rejected the shallower ordinals
  before the boundary check ran. Every indent at or shallower than the
  list's base is now ONE level, in both splitters.
- `indentOf` counted characters, so a tab and a space aliased to one level
  and `\t1. nested` / ` 2. status: resolved` resolved falsely. Indent is now
  measured in CommonMark columns (§2.2: a tab advances to the next multiple
  of 4), for the run level and the entry-boundary check alike.
- A nested run survived a fenced block. A fence is a non-list block: its
  opening delimiter ends the runs at its level and deeper, exactly as a
  paragraph after a blank does.

* fix(#3702): the indent measure is grammar-scoped — Gaps keeps next's character count

`blockStructure: false` promised the Gaps grammar byte-for-byte parity with
`next`, but the CommonMark-column indent measure added for the deferred
grammar was shared by the whole splitter core, so tab-indented Gaps input
changed entry boundaries in BOTH directions:

  `\t- a` / `  - b`  — next folded into one entry, HEAD split into two
  `  - a` / `\t- b`  — next split into two,      HEAD folded into one

`indentWidth` now keys the measure on the grammar: columns for the deferred
set, raw character count for Gaps. The opt-out covers indent semantics, not
only fences and thematic breaks.

Four cases pin both halves — the two flipped Gaps pairs, the two Gaps pairs
that never moved, and the same tab/space pairs on the deferred path returning
the opposite (column-measured) verdict by design.

* fix(#3702): the acknowledge path reads and writes through one classifier

Round 3, Blockers 1 and 3, and Minors 7 and 8 — one mechanism, so one commit.
Every consumer of an entry's lines now reads the splitter's own per-line
verdict instead of a re-derivation of it.

B1. Round 2 widened the WRITER's status-line finder to the deferred marker set
while `extractGapEntryFields` still de-bulleted line 0 only. A nested
`  * status: pending` was therefore selectable by the writer and invisible to
the reader: acknowledge rewrote it in place, returned `ok`, and the item stayed
outstanding on every later audit. Measured against a `next` build, `*`, `+` and
`1.` each resolved on base and stopped resolving at round 2's head — a
regression, not a gap in new behaviour. The hyphen form of the same shape was
already broken on `next` and is fixed here too: one classifier cannot be right
for three markers and wrong for the fourth.

`parseGapEntryFieldLine` is now the single place a line is classified as a
field, and it reports the offset at which the VALUE begins. The rewrite happens
at that offset rather than through a second regex, so a line the classifier can
select is one whose rewrite it has already located — the selection and the
rewrite cannot disagree. Both `DEFERRED_STATUS_FIELD_RE` and
`DEFERRED_STATUS_REWRITE_RE` are deleted rather than widened. A read-back guard
returns `rewrite_not_readable` rather than `ok`; it is unreachable by
construction today and is the fail-loud floor under the next divergence.

B3. This is the end state the round-3 review prescribed on both #3739 and
#3773: #3773's shared classifier, parameterised by this PR's marker set, with
this PR's two status regexes deleted. #3773 lands first. Its hyphen-only strip
is consistent with `next`'s hyphen-only splitter today, so the writer/reader
divergence is created by THIS merge, which is why widening every consumer
belongs to the PR that widens the domain.

m7. The heading path marker-stripped its lines before calling the reader, so
the reader's fence scan ran over text the splitter never saw: `- ```sh` is an
ordinary bullet to the splitter but strips to a fence opener, and a
`**Status:** resolved` after it was suppressed as fence content — a resolved
entry resurfaced as open. Stripping now happens inside the reader, after the
fence scan.

m8. `rawGapEntryText` stripped a marker off line 0 unconditionally, but on the
heading shape line 0 is the heading TEXT: `### 1. Race in the writer` was
silently renamed to `Race in the writer`, and the name is the key acknowledge
matches on. Line 0 is stripped only when the splitter accepted it as an opener.

Also removed: `splitDeferredHeadingEntries`, whose sole caller only null-checked
it (round 3, M4 — the claim was zero callers, which was wrong; the wrapper's
`.map` was waste at the one call site), and `stripLeadingBulletMarker`, which
this change leaves with no callers at all. The export surface narrows to the two
splitter regexes the behavioural parity test reads (M6).

[PEER-ASK pr-order-12d5]
q: Reviewer blocked both on merge order. I'm declaring #3773 lands first and
   building the end-state shape into #3739 now (both my status regexes
   deleted). Does that match your plan?
reply: CONFIRMED - same order, derived independently. #3773 cannot carry the
   fold: `DEFERRED_BULLET_MARKERS`/`BulletMarkers` have zero occurrences at
   `next` (verified), so the prescribed end state is not executable inside
   #3773 without absorbing this PR's work.
deadline: 03:55 UTC (answered before it)
fallback: declare #3773 first, adopt end-state shape in #3739, push+comment
decision: proceeded as stated; #3773 lands first, this PR carries the widening
   of every consumer.

Refs #3740

* test(#3702): pin the detect/strip symmetry, and drop a white-box test that could not reach it

Round 3, Blocker 2 and Minors 6 and 9.

B2. The regression shipped green because no fixture put a marker on a nested
status line. Four markers x {nested status line}, each asserting the entry
READS BACK as acknowledged rather than that acknowledge merely reported `ok` —
reporting `ok` over a line the reader skips is the whole defect. Plus the bare
capitalised `Status:` case (the reader stores it case-sensitively, so the
writer must not select it), and an idempotence test, which is the failure the
defect actually produced: the item resurfaces, is acknowledged again, and never
settles.

Each of these was run against the pre-fix build first: all five fail there and
pass here. Two further assertions in the block are labelled CONTROL because
they held pre-fix — they guard the new offset-based rewrite and the opener-flag
threading against regressing, and calling them regression tests for a reported
defect would overclaim.

M6. The round-2 parity test asserted that four writer-side regexes embedded the
same source string. That is true of a detect/read asymmetry too, so it could
not have caught B1 — and two of the four regexes were widened into `export =`
purely to let it read them. Replaced with a behavioural test that drives the
real seam: every marker that opens an entry must also resolve it through
acknowledge. The structural assertion is kept for the two splitter regexes,
which really are two copies of one alternation.

m9. `expectedResolved` was computed and immediately voided; the loop beneath it
already asserts both polarities.

m7/m8 coverage lands here too: a bullet whose content is a fence opener must
not suppress the entry's fields, and a heading beginning with a list marker
must keep it in the entry name.

* docs(#3702): document the deferred-items entry shape where the file is written

Round 3, Major 5, and #3702's own item 2. The widened grammar was documented in
the reader (`forensic-audit.md`) but not at the write site, where
`executor-examples.md` still said only "log to deferred-items.md" — so the
question the issue actually raised, which shapes count, remained unanswered
anywhere a human writes the file.

States what opens an entry (`-`, `*`, `+`, and `1.` when the list starts at
`1.`), that `1)` is not a marker here, that a separator closes the list and
fenced content is never an entry or a field, and that an entry without an
explicit `status: resolved` stays open by design.

* chore(#3702): regenerate the changeset through the generator

Round 3, Minor 10. The fragment was hand-named against 64 generated names on
`next`, and its body ran ~250 words against CONTRIBUTING's one-sentence form.
Regenerated via `npm run changeset`, which is also what the random three-word
name is for: concurrent PRs never collide.

* fix(#3702): the fence gate lives on the seam both sides call, not just the reader

Found by the pre-push adversarial review of this round, and it is a regression
this round introduced rather than a pre-existing one.

`extractGapEntryFields` applied `fencedLineSet` before classifying; the
acknowledge writer's status-line search did not. So a `status:` line inside a
fenced block was SELECTED by the writer and SKIPPED by the reader — the write
produced a line nothing reads, the read-back guard refused it, and the entry
became impossible to acknowledge at all: `audit acknowledge` raised an internal
error and `complete-milestone` halted on it.

Measured, `- alpha` / fence / `  status: pending` / fence:

  next          ack=ok                   -> reads back "acknowledged"
  round-2 head  ack=ok                   -> reads back ""      (the B1 defect)
  before this   ack=rewrite_not_readable -> refuses entirely   (worse than next)

`entryFieldLines` is now the seam — per line of an entry, the field it declares
or `null`, fences included — and the reader and the writer both go through it.
That makes "the writer cannot select a line the reader will not read back"
structural rather than asserted, which is what the previous commit's message
claimed while a second read-side filter still lived outside the classifier.

Two comments corrected with it. The read-back guard is NOT "unreachable by
construction": this round shipped a reachable path to it, which is precisely
what an invariant asserted in a comment is worth. And the M6 replacement test
put its marker only on the entry opener, so it passed against the defective
build — the exact weakness it was introduced to fix in round 2's test. It now
marks the nested status line too, and fails pre-fix like the rest.

Round-3 tests against the pre-fix build: 10 of 12 fail there, and the 2 that
hold are labelled CONTROL because they guard this round's new code rather than
pin a reported defect.

* fix(#3702): one end-of-file CRLF algorithm, adopting #3773's with its B4 closed

Round-4 M1. Two open PRs shipped two different answers to "what line ending
does an entry that ENDS THE FILE get?", and the review's ruling was that the
disagreement needs one answer, not two. Neither shipped answer was that one.
Measured on builds of both heads:

  case                                     #3739 r3   #3773   here
  undelimited single entry, CRLF preamble    pass      FAIL    pass
  LF-dominant list, one stray CRLF at EOF    FAIL      pass    pass
  (the other five)                           pass      pass    pass

This PR's content.endsWith('\r\n', matchIndexInContent) reads the terminator of
the PREVIOUS line, so it propagated an isolated CRLF into an LF-dominant list --
refuted by #3773's own LF-dominant fixture, ported here. Withdrawn.

#3773's crlfAtEof asks the right question -- does anything before the entry,
within scope, contradict CRLF -- and fails closed. But its scope goes EMPTY for
an undelimited single-entry list, because the entry-list region runs from the
first entry's start to the insertion point and those coincide; crlfAtEof('') is
false by its own before.length > 0 guard, so 'preamble\r\n\r\n- alpha' gained a
bare \n in a CRLF document. That is #3773's B4, verified by driving its head.

Adopted here with the scope widened to everything preceding the insertion point
where the preferred region is empty, rather than asserting LF from no evidence.
That only ever loosens a scope carrying zero information, and the predicate
stays fail-closed over the wider one. An entry at offset 0 of an undelimited
document has no evidence under either scope and stays LF.

Tests: 10 added. Negative control, driven -- 1 of the 10 fails against this
branch's own pre-fix head (the stray-CRLF fixture); B4 fails against #3773's
head; the remaining 8 are the scope counterexamples ported with the function,
which were regression pins in #3773 and are guards here. Each still kills a
simpler algorithm: drop any one and a refuted scope passes again.

Four deferred-items suites 450/450, 0 skipped. npm run lint:ci exit 0.

* fix(#3702): drop the unreachable rewrite_not_readable guard (B3)

Round-4 B3: the status had zero test coverage in either file. The review
offered two branches -- drive it from a test, or delete it and stop carrying an
untested terminal status. Taking the second, with the reason stated rather than
assumed.

Why it cannot be driven. Round 3 added the guard after a fenced `status:` line
proved the writer could select a line the reader would not read back. Round 3
then closed that divergence STRUCTURALLY, by routing the writer's line selection
and the reader's field extraction through one entryFieldLines seam. The guard
now detects a state construction prevents: 21 document shapes were driven
against it -- fence openers on the bullet line for every marker in the widened
set, duplicate and triplicate status lines, bolded and nested variants, fences
between duplicates -- and none reached it. The only seam that would is routing
the internal call through the module's exports so a test could stub it, which
reshapes production surface for a test.

Why leaving it undriven is not free. RULESET.TESTS.mutation-score runs Stryker
incrementally over changed files at an 80% threshold and says to treat a
surviving mutant as a failing test specification. An undriven `if` on a changed
file is exactly that, on both the condition and the .toLowerCase() comparison.

What this gives up, stated rather than hidden: if a future change re-splits the
writer's selection from the reader's extraction, acknowledgeDeferredItem returns
ok over an item that stays outstanding -- the original #3702 defect class. One
correction to the review's framing: match_verification_failed does NOT backfill
it. That check runs BEFORE the write and compares the matched span to the
target, so it cannot see a post-write read-back failure. The protection against
re-splitting is the shared seam and the round-3 tests that pin it, not a runtime
assertion. A comment at the removal site records all of this.

Removing it also drops the union member from both files, which resolves the PR
body's internal contradiction (it claimed no type-signature changes while adding
one) and the duplicate-status surface #3773 collides on.

No test changed behaviour: 450/450 across the four deferred-items suites, 149/149
across the audit suites, npm run lint:ci exit 0 -- the same figures as before the
removal, which is itself the evidence that nothing exercised the branch.

* fix(#3702): the deferred fence gate is indent-unbounded, like the rest of the grammar (M2)

Round-4 M2. scanFencedBlocks is CommonMark, which caps a fence delimiter's
indent at three spaces -- a fourth makes it an indented code block instead. This
grammar had already opted out of that cliff for entry openers ([ \t]*) and for
THEMATIC_BREAK_RE (^[ \t]*), but not for fences. So a fence at four spaces was
not a fence to the gate, and a `status: resolved` line inside it RESOLVED the
entry containing it.

That is not an exotic shape. A fenced block written under a NESTED bullet sits
at four spaces, so ordinary hand-written deferred-items.md files reach it.
Driven before the fix at indents 4, 5, 8 and a leading tab: all four silently
resolved. It is the #3702 silent-resolution defect class in a new place.

gsd-core/references/executor-examples.md, added by this PR, states flatly that
"nothing inside a fenced code block is an entry or a field". The review offered
fixing the parser or bounding that claim in three places. Fixing it -- the claim
is the one users will rely on, and the grammar had already chosen unbounded
indent everywhere else.

NO second fence dialect (the rule blankIndentedFenceDelimiters states). The
classification is still done by scanFencedBlocks, the one exported CommonMark
state machine, over a de-indented VIEW of the same lines. Run lengths, backtick
vs tilde, closer-must-match-and-not-trail, info-string rules and the
unterminated-at-EOF case remain that engine's answers. Indent is the only
dimension hidden from it, and it is exactly the dimension this grammar has
already declared it does not measure. Index alignment is 1:1 -- map preserves
length -- so every returned line index still addresses the original line.

Scope is the deferred grammar only. Both marker-parameterised call sites gate on
markers.blockStructure, which the Gaps set does not set, so Gaps reaches an empty
set. Verified, not asserted: the 47-fixture Gaps differential (marker x
line-ending x separator x fence x break x key-shape x list-shape) is
BYTE-IDENTICAL across this change, 8033 bytes both sides.

Tests: 14 added, of which 8 fail against the pre-fix source and pass here; the
other 6 are the deliberate controls -- indents 0 through 3, which must NOT move,
and the Gaps opt-out guard.

Four deferred-items suites green; the 58 suites touching uat/deferred/sectionizer
run 6045 tests with an IDENTICAL failing set before and after this change (17
pre-existing environment failures -- installs and an unpinned GSD_EMITTED_BASE;
emitted-attribution passes 259/259 in isolation with its base pinned). lint:ci
exit 0.

* fix(#3702): changeset, both prose parsers, and the minors (M3, M4, m1-m3, m5, n1-n2)

M3 -- the changeset omitted a user-BREAKING change. Measured against next: a
heading-delimited deferred-items.md written with `*`, `+` or `1.` went from
"0 entries, so complete-milestone has nothing to acknowledge and closes" to
"1 entry, the CLI writer refuses the heading shape, ACK_FAILURES accumulates,
exit 1". The `-` form already halted and is unchanged. That is release-note
material: a close that used to succeed now fails, and the correct response is to
fix the file, not revert. Also names the fence-indent fix below, and adds #3740
so #3773's issue is attributed here as it is absorbed.

M4 -- gsd-core/workflows/progress/steps/forensic-audit.md is a SECOND,
model-executed parser of the same grammar, and prose cannot carry a parity test.
Its widened text stated the start-at-1 rule, fences and separators but not the
`1)` exclusion nor the nine-digit ordinal cap, both enforced in code with pinned
tests. Both stated now, along with the round-4 fence-indent rule. (No ack
fragment: the size ratchet's currentSizes does a NON-recursive readdirSync of
gsd-core/workflows and agents, so a file under workflows/progress/steps/ is
outside its scope -- verified by reading the helper, not by the green.)

n1 -- executor-examples.md documented that the BOLDED status key is matched
case-insensitively and left the bare key's rule to inference. Driven: bare
`Status: resolved` is NOT read, so the entry stays open with no warning, while
`**Status:**` is. Stated explicitly, with the digit cap and the any-indent fence
rule (n2).

m1 -- boundary coverage was 2/3. limit (999999999.) and limit+1 (1234567890.)
were pinned; limit-1 (12345678.) added, per RULESET.TESTS.boundary-coverage.

m2 -- THEMATIC_BREAK_RE and the tab-expanding indent counter are hand-rolled
CommonMark rules with no in-repo peer to compare against, so the parity
assertion is against the SPEC: eight positive and five negative fixtures, plus
the two DELIBERATE divergences pinned as deliberate (`+` is a separator here but
not in CommonMark, because `+` is a list marker in this grammar and `+ + +`
would otherwise be a phantom entry; indent is unbounded). One fixture was
initially wrong -- `-- -` IS a CommonMark break, since the spec allows free
spacing between the three characters -- and the parser was right.

m3 -- the result union is hand-duplicated in audit.cts as part of a deliberate
structural view of uat.cjs, so the fix is not to delete a copy but to make drift
observable. Every REACHABLE status is now driven from a fixture; four of the six
(ambiguous, unsupported_heading_shape, already_resolved, match_verification_failed)
had no assertion anywhere in the suite before this. match_verification_failed is
still undriven and the test says so rather than omitting it.

m5 -- DECLINED, with the measurement. The review is right that `(\s*)` in the
opener and `/^[ \t]*/` in the reader disagree about \f, \v and NBSP, but its
prescribed narrowing was implemented, driven and REVERTED: as shipped, an entry
indented with any of those surfaces, parses its status field, acknowledges, and
reads back acknowledged -- a complete round-trip. Narrowing turns all three into
SILENTLY DROPPED entries, which is the #3702 defect class itself and the opposite
of this file's stated fail-safe rule. A latent inconsistency in the safe
direction is not worth a live regression in the unsafe one. Pinned by three
round-trip tests so the prescription cannot be re-applied silently; if it is ever
closed, the direction is to make the readers agree with the opener, not to make
the opener reject lines it accepts today.

Four deferred-items suites 475/475, 0 skipped. lint:ci and lint:changeset exit 0.
The 47-fixture Gaps differential is byte-identical at 8033 bytes.

* fix(#3702): the pinned `## Gaps` phantom now cites its issue (m4)

Round-4 m4. The second assertion in the Gaps byte-for-byte test pins a real
defect as expected output: a spaced hyphen thematic break in `## Gaps` is read
as an ITEM, so `- - -` surfaces a phantom open gap named `- -`. Reproduced on
pristine next at 389bc86e0 across nine separator shapes -- every spaced hyphen
form is affected, `---`/`----`/`* * *`/`___` are not, and the dividing line is a
space after the first hyphen (the Gaps opener is /^(\s*)(-)\s/ with no
thematic-break concept at all).

Filed as open-gsd/gsd-core#3898. The pin stays: scope-limiting Gaps is the point
of the blockStructure opt-out, and this assertion is the only thing that would
notice the Gaps path moving. What was missing was the tracking -- a pinned defect
with no issue behind it reads as intended behaviour to the next reader. The
comment now says which it is and what the expectation becomes when #3898 lands.

* fix(#3702): an unterminated fence runs to the end of its entry, never past it (B1, B2)

Round 4 de-indented every line before `scanFencedBlocks`, so a fence
opened at any indent — and `scanFencedBlocks` runs an unterminated
fence to end-of-document — so one stray delimiter swallowed every entry
after it into the entry before it. `- a` / blank / four-space ``` /
blank / `- b` yielded ONE entry where `next` yields two: a widening
that made an already-counted item vanish, on the mixed-file shape #3702
exists to close. Reproduces at indent 0 as well.

The bound is the entry. CommonMark closes a fence with its container
and a container at the next item at its level; this parser extends
that to a document-level stray delimiter, where CommonMark would
swallow to EOF and the fail-safe rule (surface, don't drop) will not.
`scanFencesFrom` reports the unterminated opener and the walk supplies
the bound — the next line shaped like a top-level item — then RESCANS
from it, so a later delimiter is read on its own terms. Still one
fence dialect: every block boundary is `scanFencedBlocks`' answer.
Entry-scoped `fencedLineSet` (the field reader) already ran an
unterminated fence to the end of its lines, so reader and walk agree
by construction.

Tests: the M2 pin that asserted `[]` for a stray fence before an item
flips (the item counts); the round-4 "runs to end-of-file, exactly as
CommonMark says" test is retitled — its assertion stands because the
bound is the entry — and extended with the next entry; a new block pins
the review reproduction at both indents, a terminated deep fence still
gating, the gated status inside the bounded fence, the rescan case, and
the heading-tokenizer caveat (at indent 0 the tokenizer applies
CommonMark's own fence rule, so a heading after a stray delimiter is
body text there, exactly as on `next`).

Reverted in isolation against the final tree: 3 named tests fail.

* fix(#3702): `0.` starts an ordered list (M1)

The start-at-1 rule applied unconditionally dropped ONLY the first item
of a `0.`-numbered list — the run then started at `1.` — which is the
mixed under-report that looks like a clean parse. CommonMark §5.2
permits any 1-9-digit start and a `0.` list is ordinary; a sentence
opening with "0." is not a shape anyone writes. The threshold is now
`> 1`. The cost is restated accurately in the doc comment and pinned:
a list starting at 2 or more, at a paragraph position, reads as prose
until its first `0.`/`1.` line — the prefix, not the whole list.

Boundary tests at the threshold itself: `0.`, `1.`, `2.` starts, `00.`/
`01.`, and the prefix-loss case. Reverted in isolation: 1 named test
fails.

* fix(#3702): a non-1 ordinal is an item wherever a list is already open at its level (M2)

The per-indent run memory recorded whether the previous opener was
ORDERED, so a bullet item closed the run and `1. a` / `- b` / `5. c`
folded `5. c` into `b` — another mixed-file under-report. In CommonMark
`5. c` there opens a fresh ordered list (start=5): a non-1 start is
refused only where it would interrupt a PARAGRAPH (§5.3), and after a
list item it interrupts nothing. `ListRuns` now records "a list is
open here"; the start rule applies where no list is open at the line's
level — the positions a sentence can occupy — so the round-2 B2 pins
(doc start, after a heading, after a paragraph) hold unchanged.

Two round-2 pins move with it, both CommonMark-backed: `1. alpha` /
`- beta` / `2. gamma` is three items, and a nested `3. status:` after
a nested bullet is a nested item (a field line, as `- status:` would
be); the "rejected ordinal is not stripped" pin is re-anchored at a
paragraph position, where it still holds. Reverted in isolation: 4
named tests fail.

* docs(#3702): the two runtime-loaded docs state the grammar the parser ships (B3, M4 parity)

`executor-examples.md` (the write-site doc) and `forensic-audit.md`
check 7 (the model-executed parser) both asserted "never silently drops
a possibly-open item" over a grammar that dropped three measured shapes.
Both now carry the round-5 grammar — `0.`/`1.` starts, a non-1 ordinal
inside an open list, an unclosed fence ending with its own entry — and
the fail-safe sentence is kept with what it does NOT cover named
beside it: a fenced line, a separator, and an ordered list numbered
from `2.` upward at a paragraph position, and nothing else.

* docs(#3702): changeset reflects the merged contract

The "Breaking, and deliberate: … HALTS complete-milestone" paragraph
described a refusal that #3781 removed from `next`; a heading-shaped
file written with a newly recognised marker now surfaces its entries
and `complete-milestone` acknowledges them in place. The fragment cites
#3702 alone — #3740 and #3775 closed on `next` through #3940 and #3989;
this PR's shared reader/writer classifier subsumes both fixes rather
than closing either issue. The round-5 grammar (ordered start, unclosed
fence bound) is stated in the user-facing sentence.

* fix(#3702): the heading-shape insert lands on a line the reader reads, and keeps a closing `#` sequence

Found by the round's pre-push adversarial review. An entry whose body ends
in a fenced block — closed, or unclosed and therefore running to the
entry's end — received `status: acknowledged` AFTER its last non-blank
line, i.e. as fence content: the writer returned `ok` and the reader
never saw the marker, the item stayed outstanding. That is the #3702
class itself (a write nothing reads), on the shape #3781 just opened.
The insert now walks back over blank AND fenced lines, classified by the
reader's own `fencedLineSet`, so the marker lands on a line the reader
reads; pinned as round-trips for an unclosed fence, a closed fence, and
a pending entry ending in an unclosed fence before a heading. Reverted
in isolation: the round-trip test fails.

Separately, the leaf line-0 rewrite (`### status: open ###`) dropped the
closing `#` sequence; it is kept now. Cosmetic, pinned.

* docs(#3702): the prose parser states the bare-key case rule; both docs say what an unclosed fence does, no more

`forensic-audit.md` check 7 called `status: resolved` case-insensitive
where the code reads a bare key lower-case only (the bolded form in any
case; the value case-insensitively) — `executor-examples.md` already said
so, the model-executed parser did not. And both docs claimed "a stray
delimiter cannot hide the entries after it", which overstates B1: an
UNCLOSED fence ends with its entry; a closed pair of delimiters is a
fence, whatever sits between them, as CommonMark reads it. Found by the
round's pre-push review.

* fix(#3702): a heading whose text is a fence delimiter is a heading, not a fence

Second finding of the round's pre-push review, one door over from the
first: for a leaf headed `### ```` (or `~~~`) the entry-level fence scan
read line 0 — the heading TEXT, not a Markdown line — as a fence opener,
so every body line was fenced: the reader read no field under it, and
the writer's marker (placed by the same scan) landed on a line nothing
reads — `ok`, item outstanding. `entryFencedLines` now owns the entry's
fence view for reader and writer alike, and a leaf's line 0 never opens
a fence (the leaf tell is `openerFlags[0] === false`; a pending or
headless entry's line 0 is a marker line, never a delimiter). Pinned for
both delimiters, read and write; reverted in isolation the pin fails.
