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

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

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

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

2e14b4df17 fix(#4415): treat an absent worktree as removed, not as a branch mismatch (#4612)
* fix(#4415): treat an absent worktree as removed, not as a branch mismatch

Claude Code removes a subagent's worktree the moment the subagent finishes with
a clean tree. A gsd-executor that committed everything — SUMMARY.md included,
under `commit_docs: true` — is exactly that case, so by the time the
orchestrator reaches wave cleanup the directory is routinely gone while the
branch it left behind is intact and mergeable.

`git -C <gone> rev-parse --abbrev-ref HEAD` fails, and nothing distinguished
that filesystem failure from a real branch disagreement: both reached the same
`if`, so the entry blocked `branch_mismatch`, NOTHING merged, and the branch was
left dangling. When the directory instead vanished after the merge landed,
`git worktree remove` failed "is not a working tree" and the entry blocked
`worktree_remove_failed`, leaving the branch undeleted and the operator to run
`git worktree prune` + `git branch -D` + `rm -rf` by hand every wave.

Disambiguated at the point of failure rather than ahead of it. A SUCCESSFUL
in-worktree read still decides identity exactly as before — a present worktree
on the wrong branch blocks, unchanged — and only a FAILED read consults the
filesystem. Two reads can fail, and they are not the same path:

  * The branch read fails with the directory absent. There is no checkout for
    identity to come from, so it falls back to `refs/heads/<branch>` read from
    repoRoot; a missing ref still blocks, so an absent worktree never becomes a
    silent pass. The SUMMARY rescue and the dirty check are then skipped.

  * The branch read succeeded and the later `status` read fails with the
    directory now absent — the harness removed it while the repoRoot-side base,
    deletion and scope checks ran. Identity was already established from the
    checkout and the rescue has already run; only the dirty decision is skipped.
    Without this, a mid-entry removal still blocked `worktree_dirty` with
    nothing merged: the same bug, one window later.

Skipping those reads is not a claim that the worktree was clean. This code
cannot tell who removed the directory, and a forced or manual `rm -rf` of a
DIRTY worktree would already have destroyed an uncommitted SUMMARY before
cleanup ran. The narrow thing that is true either way is that a missing source
cannot be read. The two reads also fail differently: the default SUMMARY finder
catches the unreadable directory and returns no files, while `git -C <gone>
status` errors — and that error is what surfaced as `worktree_dirty`. A rescue
that genuinely FAILS still blocks, since a copy that errored part-way can mean
an uncommitted SUMMARY was really lost.

Teardown prunes the stale .git/worktrees admin entry rather than removing a path
that is not there, re-reading presence instead of reusing the branch-step answer
since the harness can act in between. For an entry accepted as ABSENT it prunes
ONLY and never issues `worktree remove --force`: that entry was merged without
the rescue and dirty checks, so force-removing a checkout recreated at that path
would delete contents that never passed either one — strictly worse than the bug
being fixed. A genuine prune failure still reports `worktree_remove_failed`, and
a blocked teardown still withholds the branch delete. `git worktree prune` is
repository-wide maintenance, not an entry-scoped operation.

The presence probe resolves `worktree_path` against repoRoot, the way git does.
`normalizeCleanupManifestEntry` takes the path from the manifest verbatim, so it
can be relative, and every git call passes it as `-C <path>` with
`cwd: plan.repoRoot`; a bare `fs.existsSync` would have resolved it against the
PROCESS working directory instead. Those differ whenever cleanup runs from
elsewhere, reachable today through gsd-tools' `--cwd` override, and the mismatch
reads both ways: a present checkout reported absent — skipping the dirty check
that would have blocked it — or an absent one reported present.

An earlier cut resolved presence UP FRONT, before the branch read. That broke 52
existing tests: every cleanup-wave test uses a fake path that does not exist on
disk and injects no `existsSync`, so all of them re-routed down the absent
branch. Disambiguating at the point of failure leaves those tests reading as
they did. Three rows still needed their premise stated — each stubs a git
failure against a worktree that is genuinely present — and now inject
`existsSync: () => true`. No assertion in any of the three changed.

Fourteen rows added. Every early row held presence CONSTANT and so could not
reach the windows that matter, since the bug is caused by a directory that
changes state WHILE cleanup runs: removal after the branch read, a present
worktree whose status fails (which must still block), removal between the clean
status read and teardown, a reappeared checkout at teardown, #2852 isolation of
a blocked absent entry from the entries after it, and relative-path resolution.

Verified: ran the issue's own reproduction verbatim against a build of this
branch — `merged_removed`, merge commit present, branch deleted, no prunable
entry in `git worktree list`. The same reproduction against a build at the
merge-base returns blocked/branch_mismatch, no merge, branch present, `wt1 ...
prunable`. Five of the first eight rows go red against the true merge-base file;
the three that stay green are the safety-preservation rows. The rows added after
each review round go red against the commit that round reviewed.

* fix(#4415): build the probe-path expectation with path.resolve, not path.join

The row asserting that the presence probe resolves a relative `worktree_path`
against repoRoot failed on windows-latest while the code under test was correct.
On win32 `path.resolve` prepends the current drive to a drive-less absolute path
(`/repo/main` -> `D:\repo\main`) and `path.join` does not, so a join-built
expectation disagrees with correct behavior:

    expected: '\repo\main\.claude\worktrees\agent-a1'
    actual:   'D:\repo\main\.claude\worktrees\agent-a1'

`path.resolve` is what the fix must use — it is how git resolves `-C <path>`
against `cwd: plan.repoRoot` — so the expectation moves to resolve as well. Two
`notEqual` rows keep that from being circular: the probe must receive neither the
raw relative path nor a process-cwd resolution. Verified by mutation — dropping
the repoRoot anchoring in `worktreeExists` turns the row red.

* fix(#4415): confirm absence before skipping the rescue and dirty checks

`fs.existsSync` answers false for a genuinely missing path AND for one it
merely cannot traverse — EACCES on a parent directory, an unreachable mount.
Verified: with a parent at mode 000, `existsSync` returns false while
`statSync` throws EACCES.

That distinction carries weight here, because "absent" is what lets an entry
skip the SUMMARY rescue and the dirty check. An unreadable-but-present
worktree read as absent, so cleanup merged over uncommitted work that the
dirty check exists to refuse — and it contradicted this code's own comment
that a present checkout whose git read fails stays blocked. Before this PR a
failed git read blocked unconditionally, so treating unreadable as present is
not a new safety rule; it is the one that was already there.

The default probe becomes `statSync`, which reports WHY it failed. Only
ENOENT is absence; anything else reads as present and blocks. An injected
probe stays authoritative, so tests state presence directly with no hidden
dependency on the real filesystem, and may throw to state that a path is
unreadable.

Two rows added: an unreadable worktree still blocks as branch_mismatch with
no merge and no teardown, and a confirmed-ENOENT probe still takes the absent
path. Verified by mutation — reverting the discrimination to the permissive
`return false` turns the unreadable row RED while the ENOENT row stays green,
which is what distinguishes discrimination from over-blocking. The mutation
was confirmed to reach the compiled artifact the test loads.

Also from this round: the row named for a checkout that "reappeared" never
modeled reappearance (production probes presence once, at identification), so
it is renamed to the unconditional contract it does prove; the comment
crediting the notEqual rows with removing circularity is narrowed to what
they actually establish; and the changeset now says only a confirmed absence
takes the new path.

Found by Codex full-PR review (round 3) before pushing.

* fix(#4415): source identity from git's registration, removal from the errno

Maintainer review rejected the premise this fix rested on. It held that once the
worktree directory is gone there is no checkout to read, so identity must fall
back to `refs/heads/<branch>`. Git does not lose the binding — measured, after
`rm -rf`:

    worktree /path/to/wt
    branch refs/heads/feat-x
    prunable gitdir file points to non-existent location

The ref fallback weakened identity from "the checkout registered at this path is
on this branch" to "a branch by this name exists", which let a foreign sibling
branch merge. Identity now comes from `git worktree list --porcelain`, so the
#3677 swap control keeps its teeth on the absent path; the new swap row is what
would have caught this, and dropping the branch conjunct turns only that row red.

Two defects in the first cut of the porcelain rework, both measured rather than
reasoned about:

`prunable` is not a removal test. With a parent directory at mode 000, git prints
`prunable gitdir file points to non-existent location` for a checkout that is
STILL THERE — it cannot traverse the parent, so it reports the gitdir file as
missing. Treating prunable as "removed" would skip the rescue and dirty checks
and merge over uncommitted work in an unreadable worktree, reintroducing the
review's Major finding by another route. Each source now answers only what it can
prove: porcelain for identity, `statSync`'s errno for removal. Only ENOENT is
removal; EACCES/EIO blocks, as it did before this PR.

`git worktree prune` is repository-wide. Measured: two removed worktrees plus ONE
prune leaves neither registration behind. Reading the list per entry therefore let
the first absent entry's teardown erase the identity evidence of every entry after
it, merging one worktree per wave and blocking the rest as branch_mismatch —
worse than the bug being fixed, since a wave of parallel executors is the normal
case. The identity read is now a snapshot, captured lazily on the first entry that
needs it and reused for the wave, which is both pre-prune and off the happy path.

The `existsSync` probe and its dep locals are deleted; the filesystem is consulted
only for the errno. The comment calling repository-wide prune "Harmless" was wrong
under the new identity rule and says so now.

Tests: identity and removal are stated on their own axes rather than through one
present/absent boolean. Added the absent-path #3677 swap row, the two-absent-entry
prune row, a bare `prunable` marker row, and a fail-safe row for an unreadable
worktree list. Three mutations each kill exactly the intended rows, verified
against the compiled artifact the tests load. One fixture that still stated
presence through the removed `existsSync` seam was passing for the wrong reason
and now states both axes.

Verified: lint:ci exit 0; full suite 24/24 chunks, 37,164 tests, 0 failures;
tests/worktree-safety.test.cjs 422/422.

* fix(#4415): re-confirm absence before teardown, and prove the porcelain claim against real git

Maintainer review, Major. Presence was classified once, at identification, and
everything between that point and teardown — the base, deletion and scope gates,
and the merge itself — is a window in which a worktree can reappear. The defence
was "prune only, and a live checkout would make `branch -D` fail visibly", which
holds only while prune's own staleness check is not fooled by the same
filesystem-visibility gap that produced the false absence one call earlier. If it
is, prune clears the admin entry, `branch -D` then SUCCEEDS, and a live,
unreviewed, un-rescued worktree loses its branch.

That asymmetry is the argument for the fix: the bug this PR set out to repair only
ever BLOCKED, while this path could DESTROY state. Absence is now re-confirmed
with `confirmedGone()` immediately before teardown — no new subprocess, just the
statSync already in hand — and a reappeared directory blocks as
`worktree_remove_failed` instead of reaching prune or the branch delete.

The review was also right that the gap was known and unverified: the existing row
said so in its own comment ("it does NOT model the reappearance transition
itself"). It is modelled now, by a stat that answers "gone" at identification and
"present" at teardown. Mutation-verified: removing the re-confirmation turns ONLY
the new row red while the old "prune, never force-remove" row stays green, which
is exactly why that row could not have caught this.

Minor, same review: the #4415 block was entirely mock-based, so the factual claim
the identity mechanism rests on was asserted in comments and measured out of band
but never proved executably. Two real-git rows now prove it — that git keeps the
path -> branch binding after the checkout is deleted and marks the entry prunable,
and that it ALSO reports prunable for an unreadable worktree that is still there,
which is why removal is confirmed by errno rather than by prunable. The second row
skips as root, where mode 000 does not deny traversal.

Minor 2 (rescueSummaryArtifacts resolving worktree_path against process.cwd()
while the new code resolves against plan.repoRoot) is pre-existing and not
reachable through the CLI's same-cwd invocation; left for a follow-up issue rather
than widened into this PR.

Verified: lint:ci exit 0; full suite 27/27 chunks, 37,739 tests, 0 failures, against
the true merge-base; tests/worktree-safety.test.cjs 425/425.

* test(#4415): make the real-git rows platform-correct

The Windows conformance shard caught both rows on their first push, and both
failures were mine, not the code's.

Path separators: git reports porcelain paths with FORWARD slashes on every
platform, while `path.join` yields backslashes on win32, so `includes()` compared
separator styles rather than paths and the registration assertions failed. Both
sides are normalised before comparison now.

Premise setup: the unreadable-worktree row establishes "git cannot traverse the
parent" with mode 000, which win32 does not honour for directory traversal at all
— the row would have asserted `prunable` against a perfectly readable worktree and
failed for a reason unrelated to the behaviour under test. It now skips on win32
for the same reason it already skipped as root, with both reasons stated together.

Verified: lint:ci exit 0; tests/worktree-safety.test.cjs 425/425 locally. The
Windows shard is the real check for the separator fix, since macOS cannot
reproduce it.

* fix(#4415): warn when an entry is accepted as absent, giving prunable its consumer

Maintainer review round 3, both Medium findings — they close together, as the
review noted.

The absent path reported `merged_removed`/`ok` indistinguishably from an ordinary
merge. This code cannot tell "the harness cleanly removed a finished executor"
from "an operator or an external process removed this path": git keeps the
path -> branch registration and `statSync` reports ENOENT in both cases. Before
this path existed every anomalous absence blocked loudly, so accepting the routine
case silently took the operator's only signal away from the case that is not
routine. The module already carries an advisory channel for a materially less
risky condition — scope conformance, a few lines below — so withholding one here
was inconsistent with its own pattern.

`WAVE_CLEANUP_WARNING.ACCEPTED_ABSENT_WORKTREE` is now emitted at both acceptance
sites, carrying git's own `prunable` reason. Advisory, never a gate: the entry
still merges.

That also gives `WorktreeEntry.prunable` a consumer. It was parsed, documented as
"worth surfacing to an operator", and then never read — the errno rework made it
unused for the predicate and the parsing stayed behind. Quoting git's reason here
is what it was for.

The bare-marker test was vacuous, as the review said: it asserted
`merged_removed`, which is driven by `confirmedGone` and the branch match, not by
the bare-marker parsing it claimed to cover, so a regression in that parsing would
not have reddened it. It now asserts the parsed value reaches the warning. A bare
`prunable` line normalises to the literal 'prunable' — a truthiness signal, not a
reason — so the warning reports null there rather than quoting a marker back at an
operator as though git had said something.

`WAVE_CLEANUP_WARNING`'s locked code set is updated deliberately, with the reason
recorded in the test: the lock exists so a new advisory code is a decision rather
than something that appears because a branch needed one.

Verified: mutation — suppressing the warning at both sites turns both new rows
red; lint:ci exit 0; full suite 27/27 chunks, 38,245 tests, 0 failures;
tests/worktree-safety.test.cjs 426/426.

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

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

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

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

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

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

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

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

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

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

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

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

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

Two more findings from the continuation review, both driven:

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

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

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

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

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

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

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

ab0405ad22 test(#4514): migrate git-adjacent workflow checks to named timeout constants
Batch 3 of the ad hoc timeout literal migration (epic #4445). Replaces
every bare numeric timeout/timeoutMs object-literal property in
tests/ci-rebase-check.test.cjs, tests/gsd-validate-commit-crash-policy.test.cjs,
tests/pr-branch-planning-filter.test.cjs, tests/reapply-verify-hunks.test.cjs,
tests/ship-notes-wedged-pr.test.cjs, tests/slug-derivation-drift-guard.test.cjs,
and tests/worktree-safety.test.cjs with a named constant, per
eslint-rules/no-adhoc-timeout-literal.cjs. Removes the 7 files from the
rule's allowlist.

Mints a new shared class norm, QUICK_SPAWN_TIMEOUT_MS (10000ms), in
tests/helpers/timeouts.cjs: 5 sites across 4 of this batch's files had
independently arrived at the same value for the same shape (a cheap,
trivial subprocess/hook invocation with no real git/network/fan-out
work). No src/bin file touched, no numeric value changed anywhere.

476394689a fix(#4254): pin sequential executor to the orchestrator's validated root (#4476)
* test(#4254): sequential executor root pin — failing-first regression + matrix

The new suite executes the shipped supplied-root-pin guard against real git
fixtures (drifted primary-checkout cwd halts before the write and the FATAL
names both roots; matching cwd permits it; unexpanded/empty pins halt;
normalization forms; submodule and sibling boundaries; metacharacter quoting;
drive-letter form gate) and locks the dispatch contract across execute-phase.md,
its sequential-root-pin step fragment, and worktree-path-safety.md. The #2772
per-plan serialization assertion retargets to the fragment that now carries
those rules (ADR-857 Phase 6 ceiling), plus the host-step wiring.

* fix(#4254): pin sequential executor to the orchestrator's validated root

Sequential-mode dispatch told the executor to self-derive PROJECT_ROOT from its
own cwd; every existing guard is worktree-mode-only or self-referential, so an
executor spawned with a drifted cwd committed onto the wrong checkout silently.

- worktree-path-safety.md step 0p: mode-agnostic supplied-root pin guard,
  composed by the orchestrator at build time with the literal $ORCHESTRATOR_WT
  (git-vs-git comparison on both sides — representation-safe on Windows, the
  #4296 lesson), fail-closed on empty/unexpanded pins, registered-submodule
  allowance, warn-and-proceed only when the dispatch carries no pin block.
- execute-phase.md sequential branch: build-time embed of the bound
  <project_root_pin> via the new execute-phase/steps/sequential-root-pin.md
  fragment (ADR-857 Phase 6 frozen ceiling — the host step cannot grow; the
  wave serialization rules move with the fragment, verbatim in substance) plus
  the per-write/commit pin instruction in <sequential_execution>. Worktree-mode
  dispatch untouched (its self-derived toplevel IS correct there).
- INVENTORY rows (5 locales) + INVENTORY-MANIFEST + install-tree goldens
  regenerated for the new fragment; changeset added.

* chore(#4254): backfill changeset PR number

* fix(#4254): accept backslash-separated Windows drive pins

CI on windows-latest showed every permit-path test failing with
"Actual root: <none>": pins composed from Node's path.join arrive in the
backslash drive form (C:\Users\RUNNER~1\...), which the guard's absolute-form
gate rejected before the cwd-side root was ever computed — a legitimate
matching pin could never pass. The gate now accepts either separator
([A-Za-z]:[\\/]); git -C resolves both forms (and 8.3 short names) to the
same canonical toplevel, so the git-vs-git comparison is unaffected. Form-gate
tests cover the emitted (C:/…) and produced (C:\…) spellings plus short names.

* fix(#4254): portable drive-form gate for MSYS bash

The bracket class [\\/] that accepted backslash drive pins parses
inconsistently on MSYS bash (the Windows CI leg still rejected C:\ pins —
every permit-path test red with "Actual root: <none>"). Replace it with
standard pattern escaping outside brackets: [A-Za-z]:/*|[A-Za-z]:\\* —
the escape form is version- and build-portable. Verified across all forms:
both drive spellings accepted; bare "C:", relative, empty, and unexpanded
rejected.

* fix(#4254): runtime-generated backslash comparator + self-describing FATAL

The Windows CI legs failed every #4254 permit-path row with
'Actual root: <none>' across two prior pattern spellings ([\\/] and \\*).
Stage misattribution: <none> appears whenever the FATAL fires BEFORE the
cwd-side capture assigns ACTUAL_ROOT — the absolute-form gate was what fired.

Mechanism: the test harness spawns bash -c <script> through the Windows
command-line boundary; that round-trip applies one extra shell-quoting pass
with double-quote semantics — a backslash written twice in the script text
arrives halved, while a lone backslash survives (the pin displays intact;
row 9's pure-bash gate independently showed the halved pattern rejecting
C:\ while C:/ still passed its surviving arm). On windows-latest every pin
carries backslashes (os.tmpdir() is the 8.3 short form C:\Users\RUNNER~1\...),
so the gate ate every pin before the actual root was ever computed.

Fix, robust by construction:
- the drive-form gate generates its backslash comparator at RUNTIME
  (BS=$(printf '\134'); match [A-Za-z]:"$BS"*) — the shipped guard now
  contains no doubled backslash anywhere, enforced by a regression
  assertion on the extracted guard text;
- the FATAL self-describes: Guard stage (pin-unbound / form-gate /
  actual-capture / pinned-capture / root-mismatch) plus a Diagnostic line
  carrying git's own stderr for capture failures and both compared values
  for mismatches — future platform failures name their stage in the log;
- row 9's hand-rolled duplicate case gate (transit-fragile copy, #4296
  Minor 1 duplication smell) is replaced by driving the SHIPPED guard and
  asserting the stage; rows 2/4 pin the new stage machinery.

Validated on darwin across drift/match/relative/unbound/empty/bare-drive/
forward-and-backslash drive forms, each also re-run under a simulated
Windows transit (every doubled backslash halved) with identical outcomes.

* fix(#4254): close the empty-comparator fail-open seam in the drive-form gate

Self-review of the runtime-generated backslash comparator: if printf's
octal escape ever returned empty, the drive arm [A-Za-z]:"$BS"* would
widen to drive-RELATIVE pins (C:foo) — the construction's one theoretical
fail-open path. Fail closed with a self-describing diagnostic instead of
trusting the shell's printf.

4499933807 fix(#3802): resolve the heredoc body before validating the commit subject (#3816)
* fix(#3802): resolve the heredoc body before validating the commit subject

With hooks.community: true, gsd-validate-commit.sh blocked EVERY heredoc-form
commit with CONVENTIONAL_COMMITS_VIOLATION regardless of the message, including
Claude Code's own documented idiom:

    git commit -m "$(cat <<'EOF'
    feat(auth): add login flow
    EOF
    )"

Reproduced before changing anything: conforming heredoc -> exit 2; plain
-m "feat(auth): add login flow" -> exit 0.

Root cause is the extraction regex `-m[[:space:]]+"([^"]+)"`. Bash `[^"]`
matches newlines, so the capture ran from the quote after -m to the FINAL quote
at `)"`, swallowing the whole span. `head -1` then returned the literal
`$(cat <<'EOF'` as the subject, which can never satisfy Conventional Commits.

Fixed by not answering a regex bug with another regex. hooks/lib/git-cmd.js
already exists because "a naive regex misses all three" invocation forms, and
extractBranchArgument is the established precedent for pulling an argument off a
git command line. extractCommitSubject joins it on the same tokenizeShellLike
seam — which, checked first, already returns the entire heredoc span as ONE
token, leaving only "resolve the body to its first line" as new logic.

Because the walk starts at the subcommand, `git -C <path> commit` and
env-prefixed invocations now extract correctly too — forms the raw string scan
never handled.

Deliberately unchanged, and pinned as such: a glued `-mfeat: x` and
`--message=...` still yield no message, exactly as the regex left them. The fix
stays scoped to the reported defect rather than widening on a true observation.

Two things I got wrong and corrected by measuring rather than reasoning:

  - I expected `git commit -m ""` to be blocked. Checked against the ORIGINAL
    hook: allowed before, allowed now, identical. The scanner drops the empty
    token so it takes the null path. My expectation was wrong, not the code.
  - That exposed a false comment I had just written, claiming the exit-status
    split prevents silently allowing `-m ""`. It does not. The split IS
    load-bearing, but for a heredoc whose body's first line is blank, which
    resolves to an empty subject and is correctly blocked. The comment now names
    the real case and records that `-m ""` is not it.

Tests at both layers: 9 unit rows on extractCommitSubject beside its sibling in
tests/worktree-safety.test.cjs, and 5 behavioral rows piping real PreToolUse
payloads through the hook in tests/hooks-opt-in.test.cjs. Replacing
firstLineOfMessageArg with a plain first-line return reds 8 of them across both
files. (A first mutation attempt silently no-opped and reported green — the
mutated body is echoed in the transcript for the run that counted.)

Out of scope, per the issue: the hooks.commit_types config surface, split off by
the maintainer as #3811 and explicitly sequenced after this.

Verified: `npm run lint:ci` exit 0.

* fix(#3802): confine the fix to heredoc resolution, closing four regressions

Codex review of the first attempt. It was right, and the finding is one my own
rules already name: a true observation is not a licence to widen the diff.

The first attempt replaced the shell's `-m` extraction with a token walk. That
looked like the better abstraction — this module exists precisely because a
naive regex misses invocation forms — but selecting WHICH argument is the
message was never the defect, and changing it regressed four forms that
upstream allowed, plus opened a bypass:

  - `git commit -- -m WIP`             -- introduces pathspecs; `-m` is a path
  - `git commit --amend && echo -m WIP` a later command's flag became the message
  - `git commit -m "" --allow-empty-message`  the shared scanner drops empty
                                        tokens, so the next flag became the
                                        message
  - `git commit -m WIP`                unquoted argument
  - `-m "WIP notes <<EOF\nfix: smuggled subject"` was ALLOWED — the opener was
    recognised unanchored, so validation skipped past the real, non-conforming
    subject. An enforcement bypass, not a misclassification.

Now confined to the actual defect. The shell's `-m` capture is restored byte for
byte, and only the subject-from-message step is delegated, to a PURE STRING
helper `resolveCommitSubject()` that never tokenizes. Verified as a differential
against the upstream hook run inside the real tree: the only behaviours that
change are the two intended heredoc rows (2 -> 0); all four forms above read
identical, and the bypass case blocks.

That differential also corrected my own control. An earlier comparison ran the
upstream hook from a scratch directory, where its `lib/` could not resolve
`../../gsd-core/bin/lib/token-scanner.cjs`, so the classifier failed open and
reported exit 0 for everything. That made a real regression look pre-existing.
Re-run inside the tree, `<<-"TAG"` (a double-quoted tag nested in the
double-quoted argument) is genuinely pre-existing — the capture truncates — and
is now recorded as a known limitation rather than silently "fixed".

Also fixed from the review:
  - `<<-` strips leading TABS from body lines; returning the raw line blocked a
    conforming message.
  - a non-identifier tag such as `END-MSG` is a valid bash word and was rejected.
  - an immediately-following terminator is an EMPTY message, not a subject.
  - a node/library failure now falls back to the previous `head -1` instead of
    skipping validation, so a broken extractor degrades to old behaviour rather
    than becoming a new silent-allow path.

Tests strengthened per the review: the opener-spelling rows now assert BOTH
directions per spelling, since "conforming passes" alone would also pass if the
resolver returned an empty subject for a spelling it failed to parse. Added
differential rows pinning the five previously-allowed forms, and a row for the
bypass. Dropped two rows whose comments claimed the raw scan could not handle
`-C`/env-prefix invocations — it could; the claim was wrong.

Replacing resolveCommitSubject with a plain first-line return reds 9 rows across
both files. (Mutant body echoed in the transcript; an earlier mutation attempt
on this branch silently no-opped and reported green.)

Verified: `npm run lint:ci` exit 0.

* fix(#3802): keep the installed hook runtime-neutral

`hooks/lib/git-cmd.js` ships into every runtime, including hermes and qwen,
where tests/install.test.cjs enforces that no Claude reference leaks into the
installed tree. My JSDoc named the idiom after the runtime that documents it.

Reworded to describe the SHAPE rather than the vendor; the runtime is still
named in the changeset, which feeds CHANGELOG.md where such references are
allowed, and in the tests, which are not installed.

* chore(#3802): backfill changeset pr number

The fragment shipped with the documented `pr: 0` placeholder, which the

the PR is opened. Backfilled to 3816 now that it does.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(#3802): close the truncated-capture hole, add the required test artifacts

Review round 1. Major 3 was the one that mattered, and it disproved a claim I
had stated in falsifiable form — the PR body said only two behaviours change;
the differential found five.

Major 3 — an embedded `"` truncates the `-m` capture, so the resolver received a
PREFIX of the real subject and the length gate measured the wrong string. Before
this fix the whole form was blocked outright, so the gate was unreachable; the
fix opened the path and then mismeasured it. A new enforcement hole, so it is
CLOSED here rather than declared.

Closed precisely rather than bluntly. A first attempt refused to resolve any body
with no terminator, which also blocked commits whose SUBJECT was intact and whose
quote sat further down the body — a false positive of its own. Truncation is only
fatal to the line it lands IN, and a captured line is complete exactly when
another line follows it, because the capture kept its newline. So an unterminated
body whose subject line is followed by more text stays measurable; only a subject
line running to the end of a truncated capture falls back to the opener, which
fails the format gate exactly as this form did before the fix.

Major 1 — fast-check property rows for the new parser, via the shared seeded
setup helper rather than requiring fast-check directly, per repo convention:
totality (a security property here, since an exception on this path fails OPEN),
idempotency, and that the result is always a single line drawn from the input —
the third catches a resolver that concatenated or trimmed while satisfying the
first two.

Major 2 — the 72-char gate is now exercised at {71, 72, 73} on the RESOLVED
heredoc subject, with the fixture length asserted so a mis-built fixture cannot
silently pass. 92 chars did not show which side of `> 72` the code sits on.

Minor 1 — leading blank body lines are skipped, as git's cleanup=whitespace does.
A conforming commit written that way was still blocked, which is the same defect
class #3802 reports.

Nit 1 — a backslash-escaped delimiter (`<<\EOF`) is now the same delimiter rather
than failing closed on a delimiter that includes the backslash.

Nit 5 — changeset trimmed from 2,208 chars of design note to the user-visible
change.

Mutation discipline, including a correction to my own: dropping the truncation
guard reds the unit rows, and the pre-review naive shape reds the hook-level row
too. My first mutant did NOT distinguish the hook row — removing the guard made
an empty slice and blocked for an unrelated reason, so the row passed and looked
proven. Only mutating to the actual pre-review shape showed it discriminates.

Verified: `npm run lint:ci` exit 0.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(#3802): measure the subject as git does — strip trailing whitespace, split CRLF

git's cleanup=whitespace strips whitespace at BOTH ends of a line; the
resolver handled only the leading direction, so a 72-char subject with
trailing spaces measured 75 and stayed blocked — the defect class #3802
reports, surviving one round further (review of #3816, Major 2). The
resolved subject now drops trailing spaces and tabs; the plain non-
heredoc path is untouched, keeping the fix confined to heredoc
resolution. The length-gate boundary rows gain dirty fixtures: 72+3
trailing spaces passes, 73+1 stays blocked on LENGTH.

split('\n') left \r on every body line, so on CRLF input the delimiter
never matched: the truncation guard was inert, an empty message resolved
to 'EOF\r', and a real 72-char subject measured 73. Split on /\r?\n/
(Minor 3).

The three property tests never reached the parser — the pinned-seed
fc.string corpus contained no newline and no opener, so every property
reduced to f(s) === s (Major 1). The generator now constructs heredoc-
shaped input (all opener spellings, <<- tabs, optional terminator, CRLF)
and each property asserts a floor on inputs its corpus actually resolved.
All new rows proved failing-first against the pre-fix resolver.

Also records the unquoted-delimiter expansion limit as one JSDoc
sentence (Informational 5).

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

* fix(#3802): close two recognition bypasses, pin the dquoted-delimiter limit

Codex whole-PR review found two enforcement bypasses in the resolver:

- The opener's path prefix was \S*, which accepted `id;/bin/cat` — the
  resolver then validated the heredoc BODY while bash runs `id` first
  and git's real subject is id's OUTPUT. The prefix is now a
  path-character class; any shell metacharacter fails recognition and
  the form falls back to the opener line and the format gate.

- The blank-line skip used JavaScript trim(), whose Unicode whitespace
  class skips lines git KEEPS: a NBSP first body line resolved to the
  SECOND line while git's real subject is the NBSP line (verified
  against git stripspace — the c2a0 bytes survive). Blank is now git's
  ASCII space/tab only; a Unicode-blank line is returned and fails the
  format gate, the same fail-closed direction git takes.

Both proven failing-first at resolver AND hook level. Also: the
<<"TAG" spelling is recorded as a documented limit — the -m capture
stops at the delimiter's own quote so the caller can never deliver it
(fail closed; widening the capture would change every embedded-quote
case) — with a hook-level row pinning the limit; and the derivation
property no longer accepts '' unconditionally, only for heredoc-shaped
input, so a conditional constant-'' regression can't satisfy the corpus
floor unnoticed.

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

* fix(#3802): recognition whitespace is ASCII, and '' answers to the generator

Codex round 2: the opener's \s accepted Unicode whitespace bash does
not split on — $(<NBSP>/bin/cat was recognized here while bash reads
<NBSP>/bin/cat as the executable NAME, so recognition claimed a
substitution that does not run cat. Every whitespace position in the
recognition is now [ \t], the same ASCII rule as the blank-line skip,
proven failing-first.

The derivation property's ''-acceptance now consults GENERATION-TIME
metadata: the heredoc generator records whether it built an empty
message (terminator reachable, all scanned lines ASCII-blank, <<- tab
stripping accounted for), and '' is accepted exactly then — a resolver
conditionally degrading to '' on non-empty heredocs now fails, closing
the residual round-1 permissiveness without re-deriving resolver logic.

The changeset no longer overstates the opener spellings: it names the
capture-deliverable set and the documented <<"EOF" limit.

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

* fix(#3802): nothing after the terminator escapes measurement

Round-3 BLOCKER: everything after the heredoc terminator was silently
discarded, so `-m "$(cat <<'EOF'\nfeat: ok\nEOF\n) <200 a's>"` —
one 200+ char real subject once bash substitutes — measured 8 chars and
dodged COMMIT_SUBJECT_TOO_LONG, a hole the base did not have. The
canonical idiom's tail is exactly one closing-paren line; any other tail
now falls back to the opener line and the format gate, the pre-fix
behaviour for the whole form. Proven failing-first at resolver and hook
level, including the glued-text and second-substitution variants.

Also from round 3: `cat<<'EOF'` (no space) is legal bash and now
resolves — the token before << is still literally cat; the env-prefixed
and option-terminated spellings join the JSDoc KNOWN LIMIT list instead
(fail closed, modelling bash prefix words is cost with no reported
user); the changeset states the embedded-quote truncation limit for the
message body, not just the <<"EOF" spelling; the dquoted unit and hook
rows now cross-reference each other; and the fast-check setup helper's
docstring no longer claims property-file exclusivity.

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

* fix(#3802): glued text outside the closing quote must not shrink the measurement

Codex on the round-3 guard: bash concatenates -m "$(…)"suffix into ONE
argument, but the capture holds only the quoted part — so the resolver
measured the heredoc body (8 chars) for a 200+ char real subject, a
net-new length-gate bypass the base did not have (base measured the
opener and blocked). When the closing quote is followed by anything but
whitespace or end-of-command, the hook now skips the resolver and keeps
the pre-fix first-line subject: the heredoc form fails the format gate
exactly as on base, and the plain single-line form keeps base behavior
unchanged — both pinned as differential rows, the glued-suffix row
proven failing-first against the unguarded script.

The property generator's ''-oracle now models the post-terminator guard
it previously predated: expectEmpty requires the FIRST reachable
terminator to be followed by the one canonical closing-paren line, so a
resolver regressing to '' on a non-canonical tail (e.g. a body line that
doubles as an early terminator) fails the derivation property instead of
being blessed by stale metadata.

* chore: retrigger CI — the previous wave never started (Actions queue stall)

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

* fix(#3802): only resolve a heredoc whose body bash does not rewrite

Round-4 review found two net-new enforcement bypasses: commands the base
hook blocked (exit 2) that this branch allowed (exit 0). Both reproduced as
a base-vs-head differential against the real hook, not inferred.

The predicate "may I resolve this?" was computed from the resolver's input
string alone, while two of its determinants live outside that string:

  1. WHICH -m quote arm produced the input. Inside -m '...' bash performs no
     command substitution, so $(cat <<'EOF' is literal text and git's real
     subject is the opener line. The resolver ran on both arms, so all four
     delimiter spellings went 2 -> 0 on the sq arm — reachable by the
     ordinary slip of typing ' for ". The hook now records MSG_QUOTE and
     gates the resolver on dq; sq keeps head -1, exact base parity.

  2. WHETHER the delimiter suppresses expansion. Only <<'D', <<"D" and <<\D
     do; a bare <<D is expanded by bash before git sees it. Resolving the
     literal dodged the format gate (feat: $UNSET_VAR reaches git as feat:)
     and the length gate (feat: ${LONG} reaches it at any length). The
     opener regex now separates the backslash-quoted and bare alternatives
     and refuses the bare one — the same fail-closed rule the metacharacter,
     truncation and post-terminator guards already follow.

A test row asserted exit 0 for a bare-delimiter body, so the suite defended
the second bypass and the fix could not land without editing a test that
read as intentional. That row and its two unit counterparts now assert the
block, per RULESET.TESTS.delete-bad-tests. Two unrelated rows used <<-EOF
to exercise tab stripping; they move to <<-'EOF' so each tests what it names.

Scoping the adjacency guard to the matched arm — required by the fix above —
also removes a spurious block (round-4 Minor 1): a double-quoted heredoc
whose body mentioned a glued single-quoted token tripped the sq arm.

The JSDoc claimed <<"EOF" was unreachable through the caller and that the
bare-delimiter gap was pre-existing. Round 4 disproved both; both corrected
here, along with the matching changeset sentence.

Verified: 7 bypass commands now block at head (was allow), the #3802 fix and
plain-form parity are unchanged across 8 control commands, hooks-opt-in 44/44,
worktree-safety 401/401, property-test non-vacuity 73/200 against a floor of
20, lint:ci exit 0.

Claude-Session: https://claude.ai/code/session_01EAbQy7n4mLMB7h3TnZ8GdG

* fix(#3802): resolve only where the captured text is provably git's subject

Codex review of the full PR found two more inputs where the validated text
is not the subject git receives, both net-new bypasses (base 2 -> head 0),
plus one escalation of round-4 Minor 2. All reproduced here against the real
hook and confirmed against real commits before fixing.

BLOCKER — the matched -m need not be git's message. The capture is a search
over the whole command and the double-quoted arm runs first, so it could
select a -m that is not the subject at all. git concatenates multiple -m
values and takes the FIRST as the subject, so

    git commit -m 'WIP first' -m "$(cat <<'EOF' … )"

commits the subject `WIP first` while the hook validated the heredoc. Same
for an unquoted earlier -m, for a heredoc after `--` (a pathspec, not a
message), and for one belonging to a later `&& echo`. The mis-selection is
pre-existing; resolving it is what made it a bypass. The hook now resolves
only when nothing before the matched -m could have been an earlier message,
an end-of-options marker, or another command.

BLOCKER — cleanup mode is part of the predicate. The resolver skips leading
blank lines and strips trailing whitespace because git's DEFAULT
cleanup=whitespace does. Under --cleanup=verbatim git does neither, so a
72-char subject plus three trailing spaces is committed at 75 bytes while
the hook measured 72 — COMMIT_SUBJECT_TOO_LONG dodged. This one hides from
`git log --pretty=%s`, which strips trailing whitespace in its own output;
the raw commit object shows 75 vs 72. Any named mode other than whitespace,
in either the --cleanup= or -c commit.cleanup= form, now refuses to resolve.

MAJOR — recognition trusted any path ending in /cat, so a planted
`../evil/cat` printing `WIP injected` had its heredoc body validated while
git's real subject was `WIP injected`. Only a bare `cat` or an absolute path
is recognised now. A bare `cat` shadowed on PATH is a documented residual and
is not fixable from a string — nor a meaningful boundary, since planting an
executable already allows running git directly.

The changeset and the JSDoc both asserted that a `"` anywhere in the message
blocks. Measured false: a `"` on a later body line resolves fine, because the
subject completes before the truncation point; only a `"` in the subject line
blocks. The changeset also listed <<"EOF" as covered when it measures 2/2.
Both rewritten to claim only what is measured, and the residual false
positives are now named.

Verified: 4 + 2 + 3 new bypass commands now block, with non-vacuity controls
proving the default path still resolves; all round-4 maintainer blockers stay
closed; the #3802 fix and plain-form parity unchanged across 7 controls;
hooks-opt-in 47/47, worktree-safety 402/402, property non-vacuity 73/200
against a floor of 20, lint:ci exit 0.

* fix(#3802): scope the cleanup-mode guard to the command outside the message

The guard scanned the whole $CMD for `--cleanup=` / `commit.cleanup=`,
and the heredoc BODY sits verbatim inside $CMD, so any conforming
message that merely MENTIONED the token was refused, fell back to the
opener line, and was blocked with CONVENTIONAL_COMMITS_VIOLATION. These
are ordinary English in this repository, whose own hooks and docs
discuss cleanup modes constantly. Reproduced against the real hook:
`fix: document commit.cleanup=strip behavior` blocked, the same message
without the token allowed (review of #3816, round 5 — BLOCKER).

Scoping to $MSG_PREFIX alone, as prescribed, would have reopened the
round-4 length-gate bypass the guard exists for: git accepts the flag on
EITHER side of -m, and `git commit -m "<heredoc>" --cleanup=verbatim` is
caught today only because the scan is command-wide. Measured, not
assumed. The scan now covers MSG_PREFIX + MSG_SUFFIX — the whole command
minus the one span that is message text — joined with a space so a token
cannot be forged across the seam.

Swept the guard class rather than the reported instance. The adjacency
guard does not share the defect: an in-body `-m "foo"bar` is refused by
the already-documented embedded-quote capture limit (any `"` in the
subject line truncates the capture), and an in-body `-m ` without quotes
resolves and is allowed. Deliberately untouched.

Both directions pinned failing-first: the three false-positive rows red
against the unscoped guard, and the trailing-flag row reds against
prefix-only scoping. Each mutation was echoed back to prove it landed.

* fix(#3802): read commit options the way bash hands them to git

Round 6 reported the adjacency guard scanning all of $CMD for a glued
`-m "..."`, so a glued -m belonging to a chained-after command refused a
heredoc that was never truncated. Glue is a property of the ONE character
following the matched span, so that character is now the whole window.
Separators and redirections are excluded because bash does not
concatenate across them: in `-m "msg"&& echo hi` the argument ends at the
quote, so there is no truncated capture to defend against.

An independent full-PR pass then found three accept-direction defects
this PR had introduced in earlier rounds, each measured against a real
commit by reading the raw commit object — `git log --pretty=%s` strips
the trailing whitespace that makes the length wrong and hides it:

  --cle=verbatim         git accepts any unambiguous prefix of a long
                         option, so the mode was set by a token that is
                         not the literal --cleanup. 75-byte subject
                         recorded, 72 measured.
  -am 'WIP first'        git reads this as -a -m, so the real subject is
                         `WIP first` and the heredoc is only the second
                         message. The scan looked for a standalone -m.
  --clean""up=verbatim   bash removes quotes before git sees the
  -""m                   argument, so a spliced spelling is the same
                         option and matched no literal.

The two option-name scans now read their window with quote characters
removed, which is what bash does to it, and the cleanup class covers
git's abbreviations. The adjacency test deliberately keeps the raw text:
it asks about a literal character position, not an option name.

Narrowing the cleanup window to git's own command segment was tried and
reverted. `;`, `&` and `|` end a command only outside quotes, and this is
a substring scan, not a parse: an unconditional trim cut the window short
on `--author "a&b"`, and a quote-aware trim still cut it on `--author
a\&b`. Each hid a real trailing --cleanup=verbatim and accepted a 75-byte
subject. The resulting false positive — a --cleanup carried by a chained
command refuses the commit — is documented and pinned instead. Refusing a
commit git would take is recoverable; accepting an over-long subject is
not.

Sixteen rows in tests/hooks-opt-in.test.cjs. Seven mutations, including
both reverted narrowings, so no dead end can be reintroduced silently.

* fix(#3802): close six accept-direction bypasses in the resolve guards

Round 7's FIRST-MESSAGE GUARD Major does not reproduce. Measured against the
real hook in a complete tree at the reviewed head: the classifier gate runs
before any guard, so `git add -A && git commit …` (git->add stops on a
non-commit subcommand) and `cd dir && git commit …` (the first executable is
not git) exit 0 without a guard being evaluated. The control is the proof — a
subject the bare form blocks with CONVENTIONAL_COMMITS_VIOLATION exits 0 in
both chained forms, so the hook never validated them and cannot be
over-blocking them. The guard is unchanged; scoping this scan to $MSG_PREFIX
alone is what reopened the round-4 trailing-flag bypass.

The class was real, though, one shape further out: `FOO=bar; git commit …` IS
classified and then refused, because assignment detection is prefix-anchored
and the tokenizer does not split operators. Pinned as a counterexample and
disclosed rather than generalised away; narrowing it means changing
isGitSubcommand, the shared git-commit detector every gating hook uses, and it
fails closed.

Six accept-direction bypasses are fixed. Each let the hook resolve and ALLOW a
commit whose real subject the rules refuse; the three that turn on git's
recorded subject were confirmed against the RAW COMMIT OBJECT, since
`git log --pretty=%s` strips trailing whitespace and hid two of them:

  --cleanup=whitespace -m <72+spaces> --cleanup=verbatim  git kept 75 bytes
  -mWIP -m <heredoc>                                      git recorded `WIP`
  --mes=WIP -m <heredoc>                                  git recorded `WIP`
  -\m WIP -m <heredoc>                                    git recorded `WIP`
  git commit --amend --no-edit \n echo -m <heredoc>        echo's argument read
  --squash=HEAD -m <heredoc>                              `squash! …`

Causes: one BASH_REMATCH inspected only the FIRST cleanup directive while git
applies the last, so multiplicity now refuses rather than guesses at an
argument order a substring scan cannot recover; the option scan required a
trailing space or `=`, missing attached values and long-option abbreviations;
dequoting removed quotes but not the syntactic backslashes bash also removes;
the separator scan omitted newline; and --squash/--fixup have git compose the
subject, so the supplied message is not the subject at all. Every fix widens
refusal, the direction this file documents as recoverable.

The multiplicity count first broke the hook outright: the script runs under
`set -euo pipefail` and grep exits 1 when it matches nothing, which is the
common case, so every ordinary commit died at exit 1 with no verdict. Guarded,
and only caught because the probe runs the real hook rather than the scan.

Five new rows, all five proven red against the pre-fix hook, each carrying a
non-vacuity assertion that the canonical single-`-m` heredoc still resolves.
Changeset corrected on three counts: "all fail-closed" was wrong (persistent
commit.cleanup fails OPEN, as do the -C/-c/-F/-t message sources), "global
options are all walked through" was too broad, and the chained-before claim
now states what is measured.

* fix(#3802): stop the separator and glue classes matching a literal backslash

Round 8's Major, with two corrections to its account.

`;`, `&` and `|` are metacharacters inside `[[ ]]`, so an inline bracket
class must escape each one. POSIX bracket expressions have no escape
mechanism of their own, so on bash 3.2 -- the system /bin/bash on macOS,
already a supported target here per the `declare -A` ban in
tests/install.test.cjs -- those backslashes reach the regex engine and add
a literal `\` to the class. bash 4+ consumes them, which is why this is
invisible on a modern bash. The hazard is specific to bracket
expressions: `\(` outside one is made literal correctly on every version,
and the subject validator and the `-m` capture classes were checked and
are unaffected.

The prescribed fix is not taken, because it does not parse. Inline
`[;&|]` is a bash SYNTAX ERROR on 3.2 and on 5.3 alike -- the backslashes
exist to get the metacharacters past the `[[ ]]` parser, so removing them
leaves an unparseable script. Each class is held in a variable and
expanded unquoted on the right of `=~` instead, which is a plain regex on
both versions.

One root cause, consequences in BOTH directions. The reported half is the
separator scan over-blocking. The half not reported is the accept
direction, and it is the more serious: the glue class is NEGATED, so on
bash 3.2 a backslash-glued suffix fell inside the exclusion and the hook
RESOLVED a heredoc it should have declined -- measured exit 0 on 3.2
against the unfixed hook, exit 2 everywhere else, with a letter-glued
control refused in all four cells.

The reported repro is not actually fixed by this, and the changeset says
so. A `\`-newline line continuation carries a literal newline, which the
round-7 separator guard refuses on every bash, so that shape stays
blocked with or without this change. Narrowing the newline guard is not
attempted: telling a continuation from a separator by substring scan is
the class that was tried twice in earlier rounds and reverted both times,
and an escaped backslash sitting immediately before a real newline is
indistinguishable from a continuation. Disclosed as a known fail-closed
limit instead.

Every new row runs under each bash on the machine. Against the unfixed
hook both bash 3.2 rows go red while all four bash 5.3 rows stay green --
written the ordinary way these rows would run under PATH bash, pass
against the broken hook, and prove nothing. Two non-vacuity controls per
interpreter prove the validator is reached rather than passing
everything. All 8 rows of the established differential harness are
byte-identical before and after on both versions: no regression, no new
refusal.

* fix(#3802): remove the $ of a dollar-quote from the option-name scans

Independent round-8 review, accept direction.

The option-name windows are dequoted so they match "the command as bash
hands it to git" -- round 6 removed quote characters, round 7 removed
syntactic backslashes. Both passes missed that bash has two further
quoting forms whose introducer is a `$`: `$'...'` and `$"..."`. Removing
the quote characters alone left that `$` stranded INSIDE the option name,
so `-$"m"` dequoted to `-$m` and matched no literal, while bash passed a
real `-m` to git.

Measured on bash 3.2.57 and 5.3.15 against a real repository: the hook
allowed

    git commit --allow-empty -$"m" WIP -m "$(cat <<'EOF'
    fix: a perfectly ordinary conforming subject
    EOF
    )"

with exit 0, and `git cat-file -p HEAD` recorded the subject `WIP`.

The comparison that establishes this is HEAD-internal, not a differential:
the same command spelled `-m WIP` is refused (exit 2). The merge-base
refuses EVERY heredoc form, including a perfectly conforming one, so its
exit 2 on this input says nothing about whether any guard fired -- it is
the absence of the feature, not a working check. The same miss covered
`$'m'`, spliced `--message`, `--cleanup`, `--squash` and `--fixup`.

An option NAME finished by a command substitution -- `--clean$(printf
up)=verbatim` -- is a different problem and gets its own guard: bash runs
a program to complete the name, so the argv git receives is not derivable
from this string at all, and resolution is refused rather than guessed.
The guard is scoped to the NAME: the class is a `-`-leading token whose
characters up to the substitution contain no `=`. A substitution
supplying a VALUE -- the ordinary `--author="$(git config user.name)"`,
spaced or glued, in either window -- is untouched and still resolves,
pinned in both directions. It is a SHAPE, not a segmentation of the
command line; segmenting was tried twice in earlier rounds and reverted
both times, and that reasoning stands.

Both new rows fail against the unfixed tree with their own assertions,
proven in a complete worktree at the previous head rather than a hook
copied out of its tree.

* fix(#3802): recognise a canonical cat, not any absolute path ending in /cat

Independent round-8 review, accept direction.

Round 4 restricted heredoc-opener recognition to an absolute path, after a
relative `./cat` was measured being trusted to echo its stdin. It stopped
at "absolute", so any absolute path ENDING in `/cat` was still trusted --
the same claim the round-4 reasoning had rejected one spelling earlier.

Measured on bash 3.2.57 and 5.3.15 against a real commit: with an
executable at `/.../fake-cat/cat` printing `WIP injected`, the hook
validated the conforming heredoc body and allowed the commit (exit 0)
while `git cat-file -p HEAD` recorded the subject `WIP injected`. The
same command through `./cat` was already refused, which is the control
that shows this is the round-4 class one spelling out rather than a new
one.

Recognition is now the canonical system locations -- bare `cat`,
`/bin/cat`, `/usr/bin/cat` -- which is the only identity claim a string
can support. `/usr/local/bin` is deliberately excluded: it is
user-writable on ordinary machines, which is the plantable case this
guard exists for. Anything else falls back to the opener line and the
format gate: fail closed, exactly the pre-fix behaviour for the form.

The pre-existing residual is unchanged and still documented: a bare `cat`
shadowed earlier on PATH is indistinguishable here, and is not a
meaningful boundary -- anyone able to plant an executable on PATH can run
`git commit` directly. This hook stays an authoring guard, not a security
control.

* fix(#3802): an option name carrying a shell expansion is unresolvable

Independent review, round 9, accept direction. Four more spellings, and a
change of strategy that is the actual point of this commit.

Rounds 6, 7 and 8 each tried to EMULATE what bash does to an argument
before git sees it -- round 6 removed quote characters, round 7 syntactic
backslashes, round 8 the `$` that introduces a dollar-quote -- and each
round review found another transform that had been missed. Round 9 found
four more. All measured on bash 3.2.57 and 5.3.15 against a real
repository, each with the plain spelling of the same command as its
control (refused, exit 2) and `git cat-file -p HEAD` for the subject git
actually recorded:

    -$'\155' WIP        hook 0, real subject `WIP`   ANSI-C octal -> m
    -$'\x6d' WIP        hook 0, real subject `WIP`   ANSI-C hex   -> m
    -`printf m` WIP     hook 0, real subject `WIP`   backtick substitution
    x= … -${x}m WIP     hook 0, real subject `WIP`   parameter expansion
    -? WIP              hook 0, real subject `WIP`   pathname expansion

and the same class through the cleanup guard, where git recorded a
75-character subject the length gate had measured as 72:

    --cle$'\141'nup=verbatim, --clean`printf up`=verbatim, --cle?nup=verbatim

The last two settle it. An option name finished by a PARAMETER expansion
depends on a variable's value at run time; one finished by a PATHNAME
expansion depends on the contents of the working directory. Neither is
derivable from the command string at any level of effort, so emulation
cannot be completed -- not "has not been completed yet". A fifth patch in
that direction would have the same shape as the previous four.

The rule is therefore no longer "normalise it and match the literal". It
is: an option NAME carrying a shell expansion or quoting construct is
UNRESOLVABLE, and unresolvable refuses. One rule covers every spelling
above and every spelling nobody has thought of yet, in the fail-closed
direction. The dequoting passes are kept rather than replaced: they still
normalise the deterministic removals, so the guards RECOGNISE
`--clean""up=` and `-\m` as the options they are instead of merely
refusing them, which keeps the existing rows meaningful.

Scope is unchanged and still pinned in both directions: the class is a
`-`-leading token whose characters up to the construct contain no `=`, so
a construct supplying a VALUE -- `--author="$(git config user.name)"`,
the backtick spelling, `--date="${NOW}"`, a glob character inside an
author string, a pathspec after `--` -- still resolves. Nine such forms
are asserted to pass beside the seven that must refuse.

The class is bracket-only and holds no backslash, per round 8: a POSIX
bracket expression has no escape mechanism, and a backslash written
inside one becomes a literal member on bash 3.2.

The new rows fail against the previous head with their own assertion
message, in a complete worktree with the lib built, not a copied hook.

* docs(#3802): disclose and pin the two spellings the round-9 class over-blocks

A scoped review of the round-9 class asked one question -- does it refuse a
conforming heredoc commit that the previous head accepted -- and found two
spellings that it does. Both measured on bash 3.2.57 and 5.3.15, previous
head 518d97b64 exit 0, current head exit 2:

    git commit -S$SIGNING_KEY -m <conforming heredoc>
    git commit -m <conforming heredoc> -- -*.txt

Disclosed and pinned rather than narrowed, for two reasons.

Narrowing is not available cheaply. Dropping the bare `$` member reopens
`-$xm`: with `xm=m` bash hands git a real `-m`, which is the parameter
expansion bypass the round-9 commit exists to close. Skipping tokens after
`--` means deciding where git's options end from a substring scan, which
is the class this file has already reverted twice for opening
accept-direction holes -- a `--` inside a quoted value (`--author "a -- b"`)
would truncate the window and hide a real trailing directive.

And the limits are narrower than they look, because in both cases the
spelling a developer actually reaches for still resolves:

    -S "$KEY"  and  --gpg-sign="$KEY"        resolve
    '-*.txt', "-*.txt", ':(exclude)-*.txt'   resolve

The pathspec one is worth stating precisely: a glob only reaches git AS a
pathspec when it is quoted, because an unquoted one is expanded by the
shell before git is executed. So the refused spelling is not passing a
glob to git at all, and the spellings that do are unaffected.

Refusing a commit git would take is the recoverable direction; accepting a
non-conforming subject is not. That is the trade this file already makes
everywhere else, and it is made explicitly here.

Nine rows pin the working spellings beside the three that refuse, so a
later narrowing cannot silently drop the cases that must keep working.

* fix(#3802): join backslash-newline continuations before the resolve guards

Round 9's Major, with a correction to its diagnosis.

The cited bracket classes at :223 and :260 no longer exist -- round 8
moved both into SEP_CLASS and GLUE_CLASS, and a lone backslash before -m
resolves (exit 0) at the reviewed head on both bash 3.2.57 and 5.3.15.
What refuses the repro is the NEWLINE a `\`-continuation carries: round
7's separator guard reads any newline in a window as a command boundary,
and `git commit \` newline `  -m "$(cat <<'EOF' …` was refused for that
reason. Round 8 disclosed it as a fail-closed limit; round 9 calls the
idiom common and the limit a Major, and it is fixed here.

It was left as a limit because "is this newline a continuation" looked
like the segmentation question this file has reverted twice. It is not:
bash's rule is local and character-level. A newline preceded by an ODD
run of backslashes is a continuation and bash removes both; an EVEN run
(`\\` then newline) is a literal backslash followed by a real newline,
which IS a separator. Both scan windows are joined that way immediately
after they are cut from the command and before any dequote copy is
derived, in three bash-3.2-safe parameter expansions: every `\\` pair is
parked on \x01, any backslash-newline that remains is a lone one and is
removed, then the pairs are restored.

Measured on both bashes, both directions:

    git commit \<nl>  -m <heredoc>                 2 -> 0   the fix
    git commit \\<nl>  -m <heredoc>                2 -> 2   literal \ + real separator
    git commit<nl>  -m <heredoc>                   2 -> 2   bare newline
    -m <heredoc>\<nl>suffix                        2 -> 2   bash glues it; the glue guard sees it glued
    git commit … \<nl>  --allow-empty<nl>echo -m … 2 -> 2   the REAL newline still separates

The prescribed `[\;&|]` is not taken: a backslash written inside a
bracket expression becomes a literal member on bash 3.2, which is the
round-8 defect from the other side.

Rows run under each bash on the machine. The fix row fails against the
previous head in a complete worktree with the lib built; the four control
rows were measured against that same head and were already refused, so
they pin existing behaviour rather than the change.

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.

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

* 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).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

2f86278b5e fix(#3003): opt-in mechanism for intentional deletions in worktree.cleanup-wave (#3757)
* test(#3003): failing-first suite for declared deletions in cleanup-wave

Binds the guard's opt-in before it exists, so the suite is RED against next.

The rows that carry the weight are the over-authorization set: a directory
declaration must not authorize its children, a glob declaration must authorize
nothing, and a declaration must not act as a string prefix of another path.
Each of those BLOCKS, and each would PASS under a prefix, glob, or startsWith
matcher — which is how a path list quietly degrades into the boolean opt-in
#3003 explicitly rejected. The glob row matters most: declaredScopePrefix
already returns null ("matches everything") for a glob-leading pattern, correct
for the advisory it serves and catastrophic for a gate.

Also pinned: a failed deletion check blocks on its own reason rather than being
filtered into a pass; the block detail names only the undeclared residue so the
operator is not misdirected by paths that were fine; an entry with no
declaration blocks exactly as before; junk and non-array declarations do not
authorize; and a blocked entry still isolates rather than aborting the wave
(#2852, which must stay fixed).

Two advisory rows cover an interaction found while designing: git diff
--name-only includes deleted paths, so without unioning the declaration into
the #2596 scope check, authorizing a deletion would raise
SCOPE_OUT_OF_DECLARED against the very path just authorized.

A seeded property states the whole invariant the three over-authorization rows
sample: a deletion merges iff its normalized path is in the declared set.

* feat(#3003): declared deletions opt-in for the cleanup-wave guard

The deletions guard blocked the merge-back of any executor branch whose diff
removed a file, with no way to say a removal was intended. A plan that folded
one test file into a sibling could not be merged by the tool meant to merge it,
forcing a manual --no-ff outside the tool -- strictly less safe than what the
guard protects against.

A plan now declares removals in its own frontmatter (files_deleted), and that
list rides the same path files_modified already travels: plan-document parse ->
phase plan JSON -> the per-plan worktree gate -> record-agent/create
--deletions -> declared_deletions on the manifest entry -> the guard. The guard
blocks only the deletions NOT in that list.

A path list rather than a boolean, per the pinned decision: a boolean disarms
the guard for the whole entry, so an unexpected deletion riding along with a
declared one would pass unnoticed. Matching is exact after the module's shared
normalizer -- never a prefix, never a glob. Both would let one declaration
authorize a whole set, which is the mass-deletion accident the guard exists to
catch. That also means declaredScopePrefix is deliberately NOT reused here: it
returns null ("matches everything") for a glob-leading pattern, which is right
for the advisory it serves and would silently disarm a gate.

The block detail now carries only the undeclared residue, so an operator is not
sent looking at paths that were fine. A failed deletion check still blocks on
its own reason and is never filtered into a pass. A blocked entry still
isolates rather than aborting the wave (#2852).

The #2596 scope advisory unions the declaration into its declared set --
git diff --name-only includes deleted paths, so without that, authorizing a
deletion would immediately warn that the same path was out of declared scope.

Optional and additive throughout: files_deleted is absent from
PLAN_REQUIRED_FIELDS, a manifest entry without declared_deletions keeps the
original unconditional block, and omitting --deletions leaves the on-disk entry
shape untouched.

Supersedes the spent #2856 emitted-drift ack entry for execute-phase.md, the
same supersede that entry performed on #3370 and #3370 on #3324.

* fix(#3003): wire --deletions on every dispatch surface, not just one

Review found the feature inert on two of three dispatch paths. execute-phase.md
(harness inline) passed --deletions, but the orchestrator-worktree path
(executor-isolation-dispatch.md, worktree.create) and the Fleet-parallel batch
path (capabilities/claude-orchestration/fragments/execute-wave-pre.md,
worktree.record-agent) still passed only --files. A plan declaring
files_deleted would have merged on one path and been blocked on the other two
-- the exact bug #3003 exists to fix, left unfixed where most of the isolation
actually runs.

Worse, per-plan-worktree-gate.md already claimed --deletions was passed 'on the
same worktree.record-agent / worktree.create calls', which was false for both
untouched sites. A doc asserting coverage that does not exist is how a gap
survives review.

All four surfaces now pass the flag, verified by sweeping every .md under
gsd-core/, capabilities/, commands/, skills/ and agents/ that invokes
worktree.record-agent or worktree.create: each one that passes --files now also
passes --deletions. The isolation-dispatch note explains why this flag, unlike
--files, is not advisory -- omitting it does not skip a check, it blocks a
merge the plan declared.

Regenerates capability-registry.cjs, which the fragment edit made stale.

Neither newly-grown file needs an emitted-drift ack: executor-isolation-dispatch.md
sits under workflows/execute-phase/steps/ and execute-wave-pre.md under
capabilities/, both outside currentSizes()'s non-recursive scan of
gsd-core/workflows/ and agents/.

* docs(#3003): document files_deleted where a plan author will actually find it

The feature's entire user surface is one plan-frontmatter field, and the
canonical reference for that frontmatter -- docs/reference/plan-md.md, the table
that documents every other key -- never mentioned it. A field nobody can
discover ships as a field nobody uses. Adds the files_deleted row and an example
entry in all five locales (en, ja-JP, zh-CN, ko-KR, pt-BR), stating the property
that makes the opt-in safe: matching is exact per path after separator
normalization, with no globs and no directory prefixes, so a declaration can
never authorize more than it literally lists, and omitting the field keeps the
guard's original unconditional block.

Also corrects two claims in the scope-conformance how-to that this change made
false. Its opening paragraph described the recorded declared scope as
files_modified alone; declared_deletions is now unioned into that comparison.
Its "Renames are not detected specially" bullet asserted the deletions guard
blocks any entry whose diff contains a deletion, full stop -- which was the
whole point of #3003 and is no longer true. Reworked to say what now decides a
rename's fate: declare the old path in files_deleted and both halves become
ordinary paths for the advisory check, which is also why the old path needs no
separate files_modified entry.

Documentation that describes the pre-change behavior of the thing being changed
is worse than no documentation, because a reader trusts it.

* fix(#3003): close every review finding on the declared-deletions opt-in

Two independent isolated reviewers, correctness and security. Neither found a
blocker; both found real defects, and the directive treats a finding at any
severity as blocking. All of them are fixed here.

MAJOR -- the submodule worktree gate could not see a deletion-only plan.
per-plan-worktree-gate.md intersected $SUBMODULE_PATHS against $PLAN_FILES
alone, while $PLAN_DELETIONS was extracted and then never used. Before
files_deleted existed, a path had to appear in files_modified to be planned at
all, so the gate saw it; the new field plus the new docs telling authors a
deleted path needs no files_modified entry opened a hole where a plan whose only
submodule touch is a removal kept worktree isolation on -- the exact case #2772
disabled it for. Both channels now feed the intersection. Note the posture is
deliberately the OPPOSITE of the cleanup-wave guard: there the channels stay
apart because a deletion AUTHORIZATION must never be inferred; here they merge
because a safety fallback must never MISS a touch.

MAJOR -- same-wave conflict detection could not see a deletion. The planner's
implicit-dependency rule compared files_modified only, so plan A editing
src/x.ts and plan B declaring files_deleted: [src/x.ts] scored as conflict-free
and ran in parallel: one branch removing what the other is writing, which is the
sharpest conflict there is. Overlap is now computed across both channels.

MINOR (both reviewers, one root cause) -- the advisory union gave one field two
matching rules. declared_deletions was unioned into the scope list handed to
planWaveScopeConformance, which reads it with prefix-and-glob semantics. So a
field that is exact-match-only at the gate silently became wider at the
advisory: ["*.md"], inert at the gate, yielded a null prefix meaning "matches
everything" and muted the advisory completely, and ["src"] muted all of src/.
The union also activated the advisory on plans that declared no modification
scope at all, warning on every modified path. Replaced with subtraction from the
findings, gated on files_modified alone. One field, one rule, everywhere.

MINOR -- core.quotepath made the feature silently inert for non-ASCII paths.
git emits "tests/\303\251.ts" C-escaped and quoted, which never equals the
declared plain path, so a correctly declared deletion of tests/é.ts would block
forever with nothing pointing at the encoding. Both diffs now pass
-c core.quotepath=false.

NIT -- flag() consumed a following flag as a value, so --deletions --files x
swallowed --files and dropped both. Now treated as a missing declaration, which
fails closed. Fixed at both call sites; the helper is duplicated verbatim in
cmdWorktreeRecordAgent and cmdWorktreeCreate and leaving one would reintroduce it.

TEST -- one test passed for the wrong reason. "a declared deletion is in scope
for the advisory" asserted only that warnings omit the deleted path; under a
full revert the entry blocks first, warnings come back empty, and the negative
assertion passes anyway. It now asserts the entry actually merged, which is the
load-bearing half. Four regressions added, one per fix above.

Docs corrected rather than extended. The rename bullet in the scope-conformance
how-to claimed a rename whose delete side is undeclared never reaches the
advisory. Verified false: git's rename detection is on by default, so a pure
rename is a single R entry that appears in no --diff-filter=D output and was
never gated, before or after #3003. Only a rename that edits enough to fall
below the similarity threshold decomposes into add+delete. The pre-existing
sentence made the same wrong claim; this restates it correctly instead of
sharpening the error. The localized plan-md.md reference edits are reverted:
the PR template requires docs content added here to be English, and the
translations already lag by three fields, so English-only is the repo's
standing posture, not an oversight.

Agent-file size caps respected: gsd-planner.md is XL-tier by bytes but carries a
separate 49152-LF-CHAR cap asserted by four suites, so its edit is deliberately
terse and lands at 49141 with 11 chars of headroom, with the rationale moved to
docs/reference/plan-md.md, which has no cap. gsd-plan-checker.md lands at 49107
bytes, 45 under the LARGE cap. Both acks merged into the existing fragments that
already name those paths, since two ack sources may never name the same path.

* fix(#3003): decode git's path quoting instead of changing the git argv

The previous commit's non-ASCII fix turned the remote suite red: 44 failures,
42 of them "unexpected git call: -c core.quotepath=false diff --diff-filter=D
--name-only ...". The suite's git mocks match on exact argv, so adding two
flags to the deletions diff and the advisory diff invalidated every existing
fixture in tests/worktree-safety.test.cjs. Rewriting dozens of fixtures to
accommodate one flag would be paying a large Hyrum's-law bill to fix a small
defect.

Both execGit calls are reverted to their original argv. The C-quoting is now
decoded in normalizeScopePath instead, via a new decodeGitQuotedPath helper.
That is the better fix on its own merits, not merely the cheaper one: the git
argv is untouched so no fixture moves, the decode lands on the ONE normalizer
already applied to both sides of the comparison so the declared and reported
paths cannot disagree, and it holds regardless of the user's own core.quotepath
setting rather than only when we remember to override it.

A value not wrapped in a leading AND trailing quote is returned completely
untouched, so the plain-ASCII path -- the overwhelmingly common case -- is
byte-identical to before. Escapes decode to BYTES collected into a Buffer and
UTF-8 decoded only at the end, because \303\251 is two bytes forming one
character and decoding them separately yields mojibake. Malformed input never
throws: a trailing lone backslash or a short octal escape degrades to the
literal character, since one bad path must not take down a cleanup wave.

Caught while reviewing the helper: the non-escape branch pushed a UTF-16 code
unit rather than UTF-8 bytes. Git always escapes non-ASCII so its own output was
fine, but this normalizer runs on the DECLARED side too, and an author may write
a quoted path holding a literal é -- pushing 0xE9 alone is invalid UTF-8, so the
declaration would decode to a replacement character and silently stop matching.
That is precisely the failure this change removes, reintroduced on the other
side of the comparison. Now converts whole code points, surrogate pairs intact.

The other 2 failures: tests/parallel-dependent-plans.test.cjs pins the exact
unbackticked substring "files_modified overlap" in gsd-planner.md, and rewording
that comment to "declared-scope overlap" deleted it. The comment is restored
verbatim and the files_deleted change rides in the pseudocode and the Rule
sentence instead. Recorded in the ack fragment so the next contributor does not
rediscover it the same way.

Four regression tests cover the decode through the public cleanup-wave seam
(the helper is module-private): a declared non-ASCII deletion merges against a
C-quoted git report, the symmetric case where the DECLARATION is the quoted
form, an undeclared non-ASCII deletion still blocks with the residue naming the
decoded path an operator can act on, and a path merely containing a quote is
left alone. Plain ASCII was already covered and is not duplicated.

* fix(#3003): revert the leading-dash flag guard, the review nit was wrong

The remote suite came back with 2 failures, down from 44, and both point at the
same thing: tests/worktree-safety.test.cjs:7045 already pins the opposite
contract, deliberately.

  test('a flag-shaped --files value is not re-parsed as a flag', ...)
    recordAgent(['--files', '--branch'])
    -> files_modified === ['--branch']
    -> branch === 'worktree-agent-a1'  ("the real --branch value must be untouched")

So consuming the next argv element positionally, whatever its shape, is the
tested intent of this parser, not an oversight. The security reviewer's nit
claimed --deletions --files x would "swallow --files and drop both". It does
not: each flag runs its own indexOf, so --deletions records the literal
'--files' while --files independently still resolves to x. And that literal is
a path git never reports as deleted, so it authorizes nothing -- already
fail-closed with no guard at all. The guard bought no safety and silently
changed --files behavior along the way, outside this issue's scope.

Reverted at both call sites, which are byte-identical again, along with the test
asserting the reverted behavior and the docs sentence describing it. The nit is
recorded as REJECTED in the review artifact with the reasoning above, rather
than as fixed -- a finding that turns out to be wrong should leave a trace of
why, or the next reviewer files it again.

docs/CLI-TOOLS.md now states the positional-read behavior plainly instead, so
the next person meets it as documented intent rather than rediscovering it
through a red suite.

* chore(#3003): backfill changeset pr number to 3757

* test(#3003): cover parsePlanDocument's filesDeleted branch to clear the mutation gate

CI's Stryker shard for plan-document failed at 73.28 against a break threshold
of 75: 170 killed, 62 survived, 232 total. Eight of those survivors are the
filesDeleted block this issue added to parsePlanDocument, which shipped with no
direct coverage at all -- the field was exercised end to end through the
cleanup-wave tests, but the parser itself was never called with a plan that
declares it, so every mutant in the block lived.

Four tests, each pinned to specific mutants rather than written for coverage
percentage:

- absent key yields exactly [] -- kills the array-literal seed
  (["Stryker was here"]) and the `fmDeleted = true` conditional, which would
  otherwise produce ["true"]
- a scalar underscore `files_deleted:` wraps into a one-element array -- kills
  `fmDeleted = false`, the `&&` logical-operator swap, the `fm[""]` string
  mutation on the first operand, the emptied if-block, and the ternary's
  non-array branch
- an array-valued hyphenated `files-deleted:` maps element-wise -- kills the
  `fm[""]` mutation on the SECOND operand (only reachable when the legacy
  hyphen alias is the one carrying the value) and the ternary's array branch
- an empty list yields [] -- boundary case, and a genuinely distinct one from
  the absent key: [] is truthy in JS so it ENTERS the if, and only
  Array.isArray's true branch mapping over nothing produces the same []

Threshold arithmetic: 174 of 232 are needed for 75%, and these take it to about
178, so the shard clears with margin rather than landing on the line.

Every expected value was confirmed by executing the built parser before being
asserted, not inferred from reading the source.

69e7afd0c7 chore(#3212): bounded quantifiers over document content — prohibition with teeth — Phase 4 (#3441)
* feat(#3415): ship local/no-unbounded-quantifier, burn down ReDoS class

Phase 4 of epic #3212 (ADR-3212 §5/§7, the final phase). New rule flags
an unbounded */+/{n,} quantifier over a broad character class
([\s\S], dotAll ., or a 1-2-unit negated class like [^\n]/[^)\n] — the
exact #2128-fixed shape) applied to a regex whose match target is
data-flow-traced to readFileSync content.

eslint-rules/lib/readfilesync-trace.cjs extracts the data-flow tracer
shared with no-crlf-fragile-split (Phase 2) rather than a second copy
— no-crlf-fragile-split refactored onto it with zero behavior change,
parity-tested.

Real triage, not 798 mechanical edits: the ADR's census (2026-08-08)
screened every unbounded quantifier in the tree unscoped. Correctly
scoped to readFileSync-derived content (matching Phase 2's own G2/G3
scoping), the rule found 162 real hits across two detection waves — the
second wave (93) surfaced only after a genuine off-by-one bug in this
rule's own first draft was caught while writing its RuleTester tests
and fixed (the bug silently missed every directly-quantified [\s\S]*
with no gap before the quantifier — exactly the class this rule exists
to catch). 3 hits landed in production src/ (commands.cts, milestone.cts,
roadmap.cts) and were each empirically timed against adversarial input
(matching #2128's own measured-not-assumed precedent) — all confirmed
linear-time/benign, left unbounded with a measured-evidence comment
rather than mechanically bounded. The remaining 159 are test-file
fixture parsing (test-author-controlled, fixed-size content, not
adversarial input) — each suppressed with a specific, non-generic
reason. Zero functional behavior changed anywhere in this diff.

tests/no-pending-3212-markers.test.cjs locks the epic's own closing

* fix(#3415): correct rule category mislabel, add CI test-scope entry

An orthogonal Standards-axis review found eslint-rules/no-unbounded-quantifier.cjs
mistakenly carried meta.docs.category: 'Portability', copied from a sibling
rule without realizing what that implied: docs/contributing/cross-platform-
portability-rules.md governs an ADR-1703 rule family under a hard "zero
escape hatches" contract (tests/portability-rule-disable-ban.test.cjs's
PROTECTED_RULES bans eslint-disable for those rules entirely). This rule is
not part of that family — it's ADR-3212 (ReDoS/CWE-1333), a different epic —
and its eslint-disable-next-line suppressions (159 of them, added earlier
this same phase after empirical benign-verification) are an intentional,
correct design, not a bypass. Corrected to category: 'Best Practices',
matching the actual precedent (no-adhoc-regex-escape.cjs, Phase 1 of the
same epic, which is also correctly outside PROTECTED_RULES), and the rule's
own docstring now states this explicitly so a future reader doesn't have to
re-derive it.

Also registers a new scripts/ci-test-scope.cjs bucket so editing this rule
or the shared eslint-rules/lib/readfilesync-trace.cjs helper re-runs their
own test suites under targeted CI selection — was previously unregistered
and invisible to that fast-path (this PR's own gsd-test checkpoint runs the
full suite regardless, so this only affects future narrowly-scoped PRs).

* fix(#3415): bound no-unbounded-quantifier's own scanner (CWE-1333, ironic)

Security review found the rule meant to catch algorithmic-complexity bugs
had one of its own: hasUnboundedBroadQuantifier's negated-class inner
scan walked from each `[^` occurrence to the next `]` (or EOF) with no
bound, while the outer loop only ever advanced by one character — O(n²)
total work on a pattern with many unclosed `[^` runs. Runs unconditionally
inside checkPattern on any `new RegExp('literal string')` argument in any
linted file, before the (cheap) readFileSync data-flow gate — so a single
crafted string literal, no valid regex syntax required, could make
`npm run lint` / CI hang.

Empirically confirmed both the bug and the fix: pre-fix, n=4000/8000/
16000/32000 chars took 30.8/115.6/463.8/1874.3ms (~4x work per 2x n,
quadratic); extrapolated, the 300000-char repro from the finding would
run ~165s. Post-fix (bail the inner scan once units exceeds the rule's
own 1-2-unit scope, rather than continuing to hunt for a closing `]`),
the same 300000-char input runs in 8.7ms via the real rule module,
independently reconfirmed at 18ms via a fresh Linter.verify() call.

New regression row in tests/no-unbounded-quantifier.rule.test.cjs
asserts the RuleTester run on a 50000-char adversarial pattern
completes and returns a defined result — no wall-clock assertion
(CLAUDE.md Clock Seams / local/no-elapsed-assertion).

* fix(#3415): triage 3 new sites, re-raise ceiling after upstream batch

next merged 12 more PRs during this PR's review. Two consequences:

- tests/edit-phase.test.cjs (fix #3262, unrelated) added 3 new
  content.match(/<tag>([\s\S]*?)<\/tag>/) reads of this repo's own
  workflow .md content — the same Class A pattern as the ~159 sites
  already triaged elsewhere in this PR. Suppressed with the same
  established reason.
- lint-allow-test-rule-refs' ratchet ceiling needed re-raising again
  (301 -> 303) for the same reason as the two prior bumps: organic
  growth from unrelated, already-reviewed PRs landing concurrently,
  not a defect in this branch's own diff.

470389f3a2 chore(#3212): tokenizer-first for stateful grammars — a shared scanner — Phase 3 (#3424)
* feat(#3414): promote git-cmd.js token-walk into a shared scanner, fix #3169

Phase 3 of epic #3212 (ADR-3212 §4). New src/token-scanner.cts generalizes
hooks/lib/git-cmd.js's proven token-walk (#3129 — "has not re-opened"):
tokenizeShellLike (quote-aware shell tokenizer, byte-identical port) and
indentWidth (bullet-nesting depth).

git-cmd.js migrates onto tokenizeShellLike with zero behavior change
(parity-asserted against every existing #3129 fixture in
tests/worktree-safety.test.cjs's folded block); isGitSubcommand's phases
1-3 (env-prefix skip, executable check, global-option consume) extracted
into skipToSubcommand, shared with the new extractBranchArgument (git
checkout -b / git branch <name>) — a new capability exercising the seam
on the domain the ADR names, not a migration of existing duplicated logic
(none existed).

Fixes #3169: src/decisions.cts's parseDecisionLines couldn't distinguish
a cross-reference bullet nested under an open decision from a fresh
malformed declaration attempt. An earlier bold-run-content-classification
design was tried and disproven against the repo's own existing FIX-B
fixtures (D-02, "no colon no dash") before being adopted — both have
identical shape under any content-only rule. Nesting depth (via
indentWidth) is the actual distinguishing signal: a bullet indented
deeper than the currently-open decision's own bullet is elaboration,
folded into its text like a continuation line, never tested against the
parse-miss guard. A bullet at the same-or-shallower indent is unchanged.

Scope-narrowing disclosed, not silent: of the ADR's four named bugs
(#3197, #3169, #2570, #2528), three no longer need this phase's work.
were independently fixed and closed since the ADR was authored — #2570's
fix is already a correctly-bounded regex per the ADR's own decidability
test (no scanner needed); #2528's fix is a deliberate, twice-reviewed
non-scanner design (its own code comment records a scanner-based attempt
that regressed a symmetric case and was reverted) that this phase does
not disturb. Only #3169 required new work.

get_impact: isGitSubcommand CRITICAL/196 affected symbols,
parseDecisionLines CRITICAL/164 affected symbols (ADR §6 due diligence).

Six-gate ripple: .gitignore, eslint.config.mjs, docs/INVENTORY.md,
docs/INVENTORY-MANIFEST.json (regenerated), CONTEXT.md glossary.

* fix(#3414): add required fast-check property tests per code review

TESTING-STANDARDS.md:169 requires at least one fast-check property test
for any module that implements parsing — src/token-scanner.cts had none,
an orthogonal Standards-axis review finding. Adds two seeded property
tests (mirroring Phase 1/2's fast-check-setup.cjs convention):
indentWidth counts exactly a generated leading-space run; tokenizeShellLike
round-trips a generated array of whitespace/quote-free words joined with
single spaces.

The design doc's own "no property test needed" rationale was wrong — it
argued no algebraic law applied, but the standard is unconditional for
parsing modules regardless of whether one "feels" applicable. Corrected
in .gsd/phase/chore-3414-tokenizer-first-seam/50-test-matrix.md.

Also fixes two Spec-axis wording drifts the same review found between
the design doc and the shipped code (doc-only, no behavior change):
extractBranchArgument's documented signature dropped an unused
subVariants parameter that was never implemented, and the #3169
fail-first fixture description corrected from "15-decision plan via
cmdDecisionCoverageVerify" to the actual compact 3-decision analog via
the real blocking gate, check.decision-coverage-plan.

dc3c81e93d chore(#3212): src/pattern.cts is the sole owner of runtime-value regex construction — Phase 1 (#3416)
* test(#3412): failing-first suite for the pattern-construction seam

Phase 1 of epic #3212 (ADR-3212 §1/§2/§7). Tests only — src/pattern.cts
and eslint-rules/no-adhoc-regex-escape.cjs do not exist yet, so both
suites fail with MODULE_NOT_FOUND, which is the intended RED.

Locks the measured behavior rather than the assumed behavior:
RegExp.escape hex-escapes the leading character of nearly every string
("abc" -> "\x61bc"), so the suite asserts match-equivalence against an
inlined historical oracle (the implementation being deleted) rather
than byte-equivalence of pattern text — 200 seeded fast-check runs plus
a fixed corpus, 0 mismatches. Also locks the latent character-class
range bug this phase fixes as a side effect: a hyphen-bearing value
interpolated into [...] currently forms a real range and matches an
unintended character; post-migration it must not.

* chore(#3412): src/pattern.cts owns runtime-value regex construction

Phase 1 of epic #3212 (ADR-3212 §1/§2/§6/§7). Adds the pattern seam
delegating to the built-in RegExp.escape, deletes every hand-rolled
copy, and raises the Node floor to the Active LTS line.

The census was low, three times over. ADR-3212 counted 10 copies; a
graph query found 12; the new lint rule — once live — found 27 more.
The difference is that the census counted named helper FUNCTIONS while
the rule counts the escape SHAPE, so inline .replace(<class>, '\$&')
copies were never in scope. ADR §1's actual requirement is that no
module outside the seam escapes a value for regex use, so all of them
are, and CLAUDE.md's no-defer rule makes them this change's work.
Fourth consecutive epic here whose copy count was low — the argument
for ADR-3180 Amendment 3's "state N found by the guard" rule.

Also corrected mid-implementation: the survey reported phase-id.cts's
escapeRegex had 0 external importers. It had 8 production importers,
making its removal a public-surface change to an ADR-2121-owned module
and requiring an update to that ADR's locked-surface test. Blast
radius revised Medium-High -> High.

RegExp.escape is match-equivalent but NOT text-equivalent: it
hex-escapes the leading char of nearly every string ("abc" ->
"\x61bc"). Equivalence is proven by a seeded fast-check property test
against the deleted implementation as oracle. It also fixes a latent
bug: a hyphen-bearing value interpolated into a character class
previously formed a real range and matched an unintended character.

Node floor 22 -> 24 (RegExp.escape is Node 24+), across engines,
.nvmrc, package-lock, 9 CI matrix entries, and 5 docs. The aggregate
`required-tests` context is unchanged and no job was added or removed,
so branch protection cannot be orphaned by the dropped lanes.

Enforced by eslint-rules/no-adhoc-regex-escape.cjs (shape-matched, with
structural provenance for reviewed pattern-fragment constants rather
than a name heuristic) plus a whole-tree companion guard covering the
directories ESLint's globs miss.

* fix(#3412): close the _SOURCE guard evasion, correct two false claims

Three findings from the orthogonal review pass, all fixed.

1. The ESLint rule's `_SOURCE` provenance fallback was pure identifier-
   name matching with no binding check, so `new RegExp(userInput_SOURCE)`
   — a function parameter — sailed past the guard. That is the same
   rename-evasion class issue #3410 documents, reopened by the very
   fallback meant to complement the structural check. Now bound to the
   identifier's actual binding kind: import, require-derived const, or
   module-scope const; parameters, `let`/`var`, and unresolvable
   bindings fail closed. Four RuleTester cases cover the evasion and
   prove the legitimate cross-module case still passes.

2. src/pattern.cts's own header carried the stale pre-correction counts
   (12 copies / 17 call sites) while CONTEXT.md and the design doc
   carried the corrected ones (~39 / ~44) — a self-contradiction inside
   the PR whose entire purpose is deleting divergent copies. Rewritten,
   preserving the durable lesson: a named-function census cannot see
   inline copies; only a shape-matching guard can.

3. The claim that all deleted copies threw TypeError on non-string was
   false. phase-id.cts's copy — the one with 8 external importers — did
   String(value).replace(...) and never threw. The seam's locked
   signature does not coerce, so this is a real, now-disclosed behavior
   change rather than the pure preservation the tests asserted. Audited
   all 32 invocations across the 8 importers and 6 in-file callers:
   every one is safe by construction (upstream truthy guard or a
   string-producing derivation), verified by runtime probe against the
   compiled modules rather than by TS compilation, which cannot see a
   runtime undefined. Corrected the false claim in both the test comment
   and the design doc, and added it to Known limits.

* docs(#3412): add Changed changeset for the Node 24 floor

The only user-visible break in this phase. The escape-behavior change
is internal and match-equivalent, so it carries no user-facing note.

* fix(#3412): resolve the seam's require graph in script fixtures and packaging

Checkpoint 2 came back red with 90 failures on the node24 lane. Three
distinct defects, all introduced by routing scripts/ through the new
pattern seam, none reproducible by any local gate:

1. ~82 failures — tests/adr-index-gate.test.cjs and
   tests/removed-but-needed-lint.test.cjs copy a scripts/*.cjs into an
   mkdtemp fixture and spawn it there (necessary: those scripts resolve
   their scan root from __dirname/.., so running the real script would
   scan the real repo). Each harness hand-listed the dependencies to
   copy alongside. Adding require('../gsd-core/bin/lib/pattern.cjs') to
   gen-adr-index.cjs made both lists silently incomplete ->
   MODULE_NOT_FOUND, plus 17 downstream 'did not emit parseable JSON'
   failures from the same crash.

   Fixed as a class, not an instance: new tests/helpers/copy-script-
   fixture.cjs walks a script's transitive static relative-require graph
   and copies it, so dependencies are derived and never re-declared. It
   throws (naming the unbuilt artifact) instead of letting the child die
   with a bare MODULE_NOT_FOUND. Verified for all four seam-consuming
   scripts: gen-adr-index, lint-removed-but-needed, gen-loop-host-
   contract, sync-runtime-launcher.

2. 2 failures — scripts/ ships wholesale but eslint-rules/ does not, so
   the new scripts/lint-no-adhoc-regex-escape.cjs would be
   MODULE_NOT_FOUND in a published install (#2858 guard). Excluded from
   the tarball, matching the existing precedent for gen-emitted-
   baseline.cjs, which is excluded for the identical reason, and locked
   with a test modeled on that one. Confirmed against a real npm pack:
   890 files, 0 from eslint-rules/, and gsd-core/bin/lib/pattern.cjs
   present (so the other four scripts' requires are legitimate).

3. 6 failures — tests/phase-id.test.cjs asserted the literal escaped
   source text ('0*29', 'PROJ-42'). RegExp.escape is match-equivalent to
   the retired hand-rolled escaper but NOT text-equivalent: it hex-
   escapes the leading character and all hyphens ('0*\x329',
   '\x50ROJ\x2d42'). Verified NOT a behavior change — 576 match
   decisions across all three real interpolation prefixes, zero
   divergence. Those tests now compile each source into the same heading
   regex src/roadmap.cts's searchPhaseInContent builds and assert what
   matches and what does not, including the 'i'-flag canonicalization
   the hex escape has to preserve. Re-pinning the new literals would
   have rebuilt the same brittleness one layer down. Adds a test for the
   property the escape exists for: a dot in '1.2' must not act as a
   wildcard.

Also shares one definition of 'a require' between the packaging guard
and the fixture copier, so the two cannot disagree about what they scan.

* fix(#3412): refuse to copy a fixture dependency outside the fixture root

copyScriptWithDeps resolved each relative require and joined the
repo-relative result onto fixtureRoot. A require resolving OUTSIDE the
repo yields a '../'-prefixed relative path, so path.join climbed out of
the fixture and wrote into the surrounding temp dir (verified:
repoRoot=/repo + depAbs=/etc/passwd wrote /tmp/etc/passwd).

No script in the tree does this today, so this closes an available
escape rather than an active one. Refuses via the existing unresolved-
require path so the failure names the offending specifier. Covered by a
negative proof that the guard fires and that nothing lands outside the
fixture.

* fix(#3412): parse requires instead of pattern-matching them; restore the foreign-prefix contract

Applies all findings from the second orthogonal review round, re-run
because real code changed after round 1.

HIGH (security) — extractRequires stripped BLOCK comments before LINE
comments, so a '//' comment containing '/*' opened a phantom block
comment, and a '//' inside a string literal truncated the line. Both
hid real requires: 'const u="http://x"; require("./real.cjs")'
returned [], and four real requires in gsd-core/bin/gsd-tools.cjs were
invisible. Replaced with a real AST parse via espree.

This is ADR-3212's own Decision 4 — tokenizer-first for stateful
grammars — applied to the case it describes; comment/string/regex
nesting is exactly such a grammar, which is why the regex version was
wrong. The function was moved byte-identical out of the #2858 packaging
guard, so the bug PRE-DATES this branch and has been a live blind spot
there: a shipped script could have required an unshipped path
undetected. Fixing it makes that guard strictly stronger than on next.

espree is promoted from a transitive eslint dependency to an explicit
devDependency rather than relying on hoisting. The script parse attempt
sets ecmaFeatures.globalReturn because Node wraps CommonJS bodies in a
function, making a top-level return legal — scripts/check-coverage-gate
.cjs relies on it, and without the flag the guard throws on a file it
is supposed to scan. Verified 0 unparseable across all 324 .cjs/.js
under scripts/, bin/, and gsd-core/bin/, and 0 new violations against a
real npm pack, so the exact extractor does not newly fail the guard.

MEDIUM (security) — the repo-containment check guarded dependencies but
not the entry path. One escapesContainment predicate now guards both.

LOW (security) — containment was lexical while fs follows symlinks, and
a directory symlink could mint a fresh dedupe key per level. realpath
now resolves both repoRoot and each dependency before the decision, and
the realpath-derived path is the dedupe key. Destination layout still
uses the original repo-relative path, so copied trees are unchanged.

MAJOR (standards) — the round-1 behavioral rewrite of phase-id tests
lost the foreign-prefix contract: every assertion was satisfied by an
impl returning [A-Z]+\x2d42, i.e. ANY project code — the exact #3599
bug class the exact-source prevents. The literal assertions it replaced
were catching this. Now asserts the compiled regex REJECTS a different
prefix with the same number.

MAJOR (standards) — the test hand-duplicated production's heading regex
with no parity guard (CLAUDE.md's 'Generative Fix Divergence'). Removed
the parallel surface instead of policing it: src/roadmap.cts exports
buildPhaseHeadingRegex, searchPhaseInContent calls it, the test imports
it. Byte-identical .source and .flags verified for both escaped forms.

MINOR — '..foo' no longer false-flagged as an escape; the inverted
spurious-vs-missing doc claim corrected; the dead allow-test-rule
header removed.

* chore(#3412): backfill changeset pr number to 3416

* fix(#3412): make the escape guard's own regex linear, reword an injection-scan collision

Two CI failures on PR #3416, both in code this branch added.

CodeQL js/redos (high) — REPLACE_CALL_RE's outer alternation let a
bracket run be consumed EITHER by the character-class branch OR one
character at a time by the trailing catch-all, so a failing match
explored both parses of every pair. Measured on the real regex:
n=26 -> 204ms, n=28 -> 791ms, n=30 -> 3475ms, a clean 2^n. This script
scans repo source, so a file with a long bracket run after '.replace(/'
would hang CI outright — a guard against undisciplined pattern
construction was itself the worst pattern in the diff.

Fixed the way ADR-3212 already prescribes: the catch-all branch now
excludes '[' and ']' so a bracket can only be consumed by the class
branch (this is what makes it linear), and every quantifier is bounded
(the locked bounded-quantifiers decision) as a second line of defense.
Now 0ms at n=2000. Disclosed coverage tradeoff, recorded at the
constant: a regex literal with a BARE unescaped ']' outside a class is
no longer matched by this backstop. No census shape has that form, and
the AST rule remains the primary detector.

Verified the guard did not go blind doing it: a real census-shape
violation is still reported, and an allow-adhoc-regex-escape
suppression comment is still honored.

Regression test drives the exported findViolations on a
2000-repetition adversarial input and asserts the RESULT. It makes no
wall-clock assertion — elapsed-time tests are forbidden — so a
regression surfaces as a harness timeout, which is the correct signal.

Prompt injection scan — 'must not act as a regex wildcard' in a test
comment matched the scanner's jailbreak pattern act\s+as\s+(a|an|if|
my). Reworded to 'behave as'. Deliberately NOT allowlisted: silencing a
whole test file over one phrase would blunt the scanner permanently,
and the comment has nothing to do with injection.

Neither failure was reachable from the remote runner — CodeQL and the
injection scan are not in that matrix, so the sha it passed was green
and still wrong.

eae2b52e4a fix(#3309): W020 fires on any degraded worktree scan, not just real failures
gsd-test found buildWorktreeHealthField collapsed every
inspectWorktreeHealth failure reason (git_timed_out, git_list_failed,
not_a_git_repo) into one UNREADABLE scope, discarding which one. The
migrated checkW020 then warned unconditionally on any UNREADABLE
scope — but the original (verify.cts:2202-2217) only warned on
git_timed_out/git_list_failed, staying silent on not_a_git_repo (a
.planning/-only fixture with no git repo at all is not a degraded
scan, just the absence of one). This spuriously degraded every test
fixture that isn't a real git repo.

planning-snapshot.cts's worktreeHealth field now carries `reason`
through instead of discarding it; checkW020 branches on it exactly
like the pre-migration code did.

a5706bd39d enhance(#2596): validate a wave branch's committed diff stays in its declared scope (#3264)
* test(#2596): failing-first suite for worktree-wave scope conformance

Binds the advisory diff-vs-declared-scope check to behavior before it exists:
the pure coverage predicate, the SUMMARY-artifact exemption and its parity with
the rescue walker, the gauntlet integration (never flips ok, degrades on a git
failure, survives a later block), the manifest normalizer's files_modified
handling, and the --files negative-input matrix on record-agent/create.

Refs #2596

* enhance(#2596): warn when a wave branch commits outside its declared scope

The worktree-wave merge gauntlet validated branch, base, deletions, SUMMARY
rescue and a clean worktree, but never compared a plan branch's actual
committed diff against the files_modified the plan declared — so an executor
that committed outside its brief merged into shared phase state silently.

Adds an advisory scope-conformance check: when the manifest entry carries a
declared scope, the gauntlet diffs HEAD...<branch> and appends one structured
warning per path outside it. It never flips ok and never blocks the merge;
promotion to a hard gate is a separate, disclosed change. With no declared
scope no git subprocess is spent at all.

Refs #2596

* docs(#2596): document the advisory worktree-wave scope-conformance check

Records the optional --files flag on worktree record-agent/create, the
advisory warnings channel cleanup-wave now emits, and its two deliberate
noise limits (SUMMARY-artifact exemption, literal-prefix glob matching).
Wires execute-phase to pass the plan's already-parsed PLAN_FILES.

Refs #2596

* fix(#2596): close review findings on the scope-conformance advisory

- share one path normalizer between the SUMMARY-artifact predicate and the
  scope comparison so the exemption and the check cannot drift
- wire --files into the orchestrator-worktree dispatch, which created a
  worktree but never declared its scope, so the advisory silently did not
  apply on that backend; ADR-1239 requires both adapters share one check
- correct the now-false blockquote claiming the check does not exist yet
- add the fast-check property tests the repo requires for parser logic
- add the record-agent/create parity test that Generative Fix Divergence
  requires for two surfaces implementing one rule

Refs #2596

* fix(#2596): keep execute-phase.md under the frozen pre-phase-6 byte ceiling

The one-sentence note added with the --files flag pushed execute-phase.md to
93708 bytes, past the ADR-857 PRE_PHASE6 cap of 93600 — the tightest of the
three workflow size gates, and a hard cap an acknowledgment cannot clear. It
failed three tests plus the differential attribution check.

Condense the note to a one-line pointer (93543, 57 B of headroom); the full
explanation already lives in docs/CLI-TOOLS.md and the dispatch step. The flag
itself stays in the command, because the orchestrator reads this workflow at
runtime and cannot pick it up from docs/.

Acknowledge the remaining 143 B of growth by appending to the existing
execute-phase.md fragment rather than adding a second one — the ack lint
rejects two sources naming the same path.

Refs #2596

* fix(#2596): make the execute-phase.md edit net-negative, not merely under the cap

The size gate on this file is two assertions, not one: bytes < 93600 AND
bytes <= 93400. The base is exactly 93400, so the file is at its budget and
any growth trips the margin assertion — the previous fix cleared the ceiling
but not that.

Move the --files explanation to per-plan-worktree-gate.md, which already owns
PLAN_FILES and carries no cap, and reclaim the rest from two clauses in the
sentence being edited: the cleanup-wave rules phrasing, and a 'non-zero exit'
the very next sentence already states. execute-phase.md ends at 93392, eight
bytes below base. The flag itself stays in the command — the orchestrator
reads this workflow at runtime and cannot pick it up from docs/.

With no growth left, the acknowledgment is unnecessary and its byte delta was
no longer true, so the shared ack fragment is restored byte-identical to base.

Refs #2596

* docs(#2596): add the how-to for interpreting scope-conformance warnings

The docs for this change were entirely Reference — the flag and the warning
codes — with the task-oriented quadrant empty. Adds the page that answers the
question an operator actually has when the advisory fires: what the two codes
mean, that nothing is blocked so there is no failure to hunt for, how to tell
whether the executor over-reached or the plan under-declared, and the three
ways the check legitimately stays silent so an absence of warnings is not
mistaken for proof of conformance.

1d208e5af6 test(#3144): bound the git/worktree cluster onto the process seam (#3152)
* test(#3144): bound the git/worktree cluster onto the process seam

Migrates 180 unbounded sync spawn sites across 19 files. Every previously
unbounded call now carries an explicit timeout with a comment giving the
number and why.

The migration is not a callee swap. execSync and execFileSync throw on a
non-zero exit and the seam never does, so each site was classified first:
sites that rely on the throw route to gitOrThrow, and sites that already read
.status to detect an EXPECTED non-zero -- an intended cherry-pick conflict, a
rev-parse outside a repo driving a skip -- route to the never-throwing runGit
instead, which would otherwise throw on exactly the exit being probed for.

Two same-named git() helpers in worktree-cleanup.test.cjs have different
return contracts, one trimmed and one raw; both are preserved rather than
unified.

Collapses five hand-rolled throw wrappers onto one throwIfFailed in
git-fixture.cjs, which gitOrThrow now also uses so the shape cannot drift.

Allowlist drops 139 to 120; BASELINE lowered to match.

* test(#3144): fix pre-PR review findings

Documents throwIfFailed in the CONTEXT.md glossary and CONTRIBUTING.md --
it became the shared throw mechanism without either doc naming it.

Routes the sixth and seventh hand-rolled copies of the throw shape through
throwIfFailed (worktree-baseref-install, worktree-safety-reap); the first
consolidation missed both.

Converts ci-rebase-check's 8 fixture-setup calls from unchecked runGit to
gitOrThrow so a failed setup step aborts where it fails rather than
surfacing later as a confusing failure against the wrong subject.

Adds 12 direct unit tests for throwIfFailed, which until now was only
exercised transitively.

Splits verify.test.cjs's non-git grep/sed bound off GIT_TIMEOUT_MS.

10da377794 fix(#3021): recognize worktree-wf_* branch namespace in all guards (#3109)
* fix(#3021): recognize worktree-wf_* branch namespace in all guards

The Claude-orchestration Workflow backend (#1143) creates per-plan
worktrees on branches named worktree-wf_<runid>-<n>. Four independent
copies of the agent branch allow-list regex (^(worktree-)?agent-...) never
learned this namespace:
- hooks/gsd-worktree-path-guard.js:176 — FAILED OPEN (process.exit(0)),
  silently disabling path containment for exactly the concurrent dispatch
  mode where cross-worktree writes are most likely
- src/worktree-safety.cts:21 — silently dropped cleanup-wave manifest
  entries
- agents/gsd-executor.md:503 — FATAL halt on branch check
- gsd-core/references/worktree-branch-check.md:33 — same FATAL halt

Extended all four to ^((worktree-)?agent-|worktree-wf_)[A-Za-z0-9._/-]+$.
The path guard now correctly blocks cross-worktree writes for Workflow-
backend branches instead of no-op'ing.

a7fdedac6a test(#3103): drive the orphan reaper through its injected dependencies
Thirty-four tests covering every branch in the reaping path that no test
reached, which was all of the fail-closed ones. The function has always
accepted an injectable dependency bag; nothing used it. Every existing test
drove real git and injected only the clock and the liveness probe, so each
guard that exists for a failure — an unreadable git dir, a null directory
listing, an unresolvable remote ref, a missing pointer file, an unlocked
sibling, an ambiguous remote — had never executed. They are now driven by
injecting exactly the fault that selects them, and each asserts its specific
status and reason rather than that something happened.

The last one needed no new mechanism, only the right one. It was reported as
unreachable without a cross-user PID, but the default liveness helper is
reachable by not injecting over it and patching process.kill, which is the
deterministic injection this repo requires over real OS conditions. Its three
outcomes — EPERM, ESRCH, and a clean return — now assert their verdicts.

The assertions were kill-tested rather than assumed. Against mutated copies of
the built module, renaming the six reason strings fails eighteen tests,
neutralising the fail-closed returns fails seven more, dropping the
ambiguous-remote guard fails one, and removing the prune catch and its timeout
guard fails both prune tests. Flipping the EPERM arm to false turns a skip into
a reap and fails that test.

Four places where production folds distinct causes into one verdict are
recorded in the tests rather than papered over. A lock is too fresh whether its
mtime is unreadable or merely recent; a branch tip fails to resolve for three
different reasons; a PID reads as alive whether the owner lives or the probe
threw. Where the return value cannot separate them the tests assert the git
call sequence instead, and where even that cannot, the test says so.

Six weak assertions already in the older file are replaced rather than left
beside the new ones: five guarded their assertions behind `if (entry)`, so a
missing entry skipped the check and passed, and one asserted only that the
reaper returned a non-empty array. Three JSON parses wrapped in doesNotThrow
now parse directly, so a malformed payload reports its own syntax error
instead of a generic message.

7dd9e59f6b test(#3090): stop exempting violations under categories that do not fit
An allow-test-rule annotation citing a category that does not apply is worse
than no annotation, because it reads as reviewed. Eight were confirmed by
reading the assertions each one covered, and auditing the rest found five more
plus one refutation — a converter test whose wording described the wrong
mechanism while the covered assertion genuinely was deployed-text.

The instructive one used the CANONICAL string for the same mistake: STATE.md
command output labelled as a deployed artifact. A canonical string is not
evidence the category fits, which is why normalising strings alone would have
laundered the problem rather than fixed it. Every mapping the audit had inferred
rather than code-verified was spot-checked before rewriting, and the ones that
turned out not to fit were re-annotated rather than relabelled.

Fourteen STATE.md assertions had a typed extractor available all along and now
use it; their annotations came out because nothing needs exempting. Eight
assertions genuinely need a production change first — CLI stdout and stderr with
no structured mode — and are tagged pending-migration-to-typed-ir citing #3090,
which is what that category is for. It had zero real uses before this, while one
file carried a real citation to migration issue #2974 under a non-canonical tag.

Six annotations covered assertions that do no text matching at all. An exemption
for a violation that does not exist is noise that makes the real ones harder to
audit; those are removed.

atomic-write-coverage gains the annotation it always warranted — its own
docstring describes a structural-regression-guard while the file carried none.

Fifty-nine non-canonical strings across roughly thirty files are normalised, and
the allow-test-rule allowlist is regenerated to match. 472 annotations became
463: every one now uses a canonical category, and the two remaining
non-canonical strings are ESLint RuleTester fixtures, not annotations.

9723d2b7e0 test(#3090): assert which value, not which type
Nine assertions drove a real fault through a real seam and then checked only
that the call did not throw, or that a result was a string, a boolean, an
array. Each passed whether the code was right or wrong. #3050 is the canonical
instance of the shape: its counter-test asserted effectiveRoot was a string and
never which root, so a silent misroute passed it.

All nine now assert the exact verdict, derived from the production branch each
one reaches and traced back to source rather than taken from the survey.

One was worse than a weak assertion. The test targeting resolveWorktreeLinkage's
main_worktree path used createTempGitProject, which always seeds .planning/ —
so the reason was always has_local_planning and the git-dir comparison the test
appears to exercise was unreachable from its own fixture. It was not asserting
loosely, it was pointed at the wrong path. The fixture now builds a git project
without .planning (projectDoc had to be disabled too, since it defaults to git
and would have re-seeded it), and the test reaches the branch it names.

Another had no reason assertion anywhere in the file while its four siblings all
pinned theirs — the odd one out rather than a convention.

The last is mine. The parity guard shipped in #3077 checked typeof and
doesNotThrow across four ExecGitFn seams, and that PR described it as failing
"the moment any site re-grows its own shape". It could not: a site returning a
different value of the same type passed it. All four benign-passthrough outputs
are derivable exact values, so it now asserts them and the claim is true.

Test names that promised more than their assertions established are corrected to
match what they prove.

53ea8e0664 fix(#3057): make a guard's failure distinguishable from its benign result — Wave 1 (#3088)
* fix(#3057): refuse the write when the duplicate scan cannot complete

writeManifest documents itself as a fail-closed duplicate guard: if any
existing manifest shares plan_id with a different, non-terminal job_id it must
refuse, because dispatching again would duplicate the external job.

It could not honour that. The scan reads every sibling manifest looking for the
duplicate, and an unreadable or unparseable sibling was `continue`d past. If
the corrupt file was the one holding the live duplicate, the scan found nothing
and a duplicate external job dispatched.

The asymmetry is what gives it away: a malformed TARGET refused with
malformed_existing because clobbering is unacceptable, while a malformed
SIBLING was skipped — yet siblings are the only thing the duplicate check
reads.

Adds a scan_incomplete verdict that refuses and names the offending file, so an
operator can quarantine or repair it. Fail-closed alone would let one stale
corrupt manifest wedge every dispatch for that planning dir permanently; naming
the file is what makes refusing survivable. malformed_existing is untouched, so
the target/sibling distinction stays visible. The docstring is updated — it
previously stated a rule the function did not keep.

memFs() gains an optional failReads map so these branches are reachable at all;
they had zero coverage because the fake could not express a per-file read
fault. The signature is additive and every existing caller is unchanged.

The regression is proved by a pair, not a single test. A control writes a
readable sibling holding a genuine non-terminal duplicate and asserts
duplicate_plan_id, establishing the scenario is real; the regression then makes
that same path unreadable and asserts scan_incomplete. A first draft of this
test used a corrupt-JSON fixture containing no plan_id at all while its comment
claimed otherwise — it duplicated the unparseable-sibling case and proved
nothing, which is the defect class this phase exists to remove.

* fix(#3057): make a guard's failure distinguishable from its benign result

Wave 1 of the negative-space backfill: the branches where a guard that could
not verify something reported the same value it reports when everything is
fine. That indistinguishability is the defect; every fix here makes the two
states tellable apart, and every test proves it with a pair — one for the
failure, one for the benign case. A single test cannot establish that two
states are distinguishable, which is the whole property being fixed.

state.cts phaseInventoryProvider returned null for both a real disk-scan
failure and a genuinely empty phases dir, so `state rebuild` could report
success while phase-table reconciliation never ran. It now returns a
discriminated result and the CLI surfaces phase_inventory_scan_failed plus a
reason. The reason field turned out never to have been wired into the emitted
JSON at all — it existed only as an internal variable — so a test could only
assert on the operator-facing note. It is a real field now.

state.cts treated an unreadable lock body the same as an empty one, applying
the 1-second stealable floor. A lock we cannot read is not a lock we know is
stale; an unreadable body is now held to the deadman ceiling like a live
holder.

verification.cts findStaleVerificationSummary returned null on any fs, scan or
clock failure — meaning "not stale". It now returns a discriminated
StaleCheckResult and the caller records that the check was indeterminate.

git-base-branch resolveBaseBranch returned 'main' both when no candidate branch
existed and when every git tier timed out. A diagnostics variant now reports
whether the answer was verified, and the CLI writes an unverified-fallback note
to stderr. The stdout contract five workflows parse is untouched.

worktree-safety snapshotWorktreeInventory left exists:true when statSync threw,
so a guard that could not check reported the worktree present; exists is now
tri-state and a stat failure surfaces as an 'unverified' finding.
planWorktreePrune reported 'no_worktrees' for a parse failure, which is not the
same as an empty list — and it drives a prune. It now reports 'parse_failed'.

Fixing the inventory change exposed a second fail-open in verify.cts: the
validate-health consumer silently dropped findings whose kind it did not
recognise, so the new kind would have vanished. That is closed too — worth
noting that the survey enumerated producers of degraded verdicts, not consumers
that discard them.

worktree-base-ref and state-transition gain the distinguishing signal without
changing what they do: headAbsenceVerified, and a phase-inventory scan meta.
Whether those guards should ACT differently is a product question this change
does not answer, and both are flagged rather than quietly settled.

rescueSummaryArtifacts is left alone: rescuing on an uncertain cat-file is
deliberate per #2556. It now has tests proving it, and a recorded negative
finding — git cat-file -e returns 128 for both "absent from HEAD" and a fatal
error, so "uncertain" and "certain-and-fine" are not separable at the git
level.

* test(#3057): assert typed values, not rendered text

Ten assertions in the rebuild CLI suite matched substrings of produced output —
STATE.md body fields, a markdown table row, an audit-log heading, and JSON keys
read as text. CONTRIBUTING prohibits that: if the code under test produces
text, the test asserts on its structured surface instead.

No production surface had to be built. Every one already existed and was
already compiled into bin/lib: stateExtractField for body fields,
parseMarkdownTable for the phase table, collectSection for the audit-log
section, and result.data.log — already a typed RebuildLogEntry[]. The tests
were matching rendered text sitting next to the structured data.

One of those assertions was passing for the wrong reason. `stdout.includes
('rebuilt')` matched the JSON KEY name, not a value: the dry-run path emits
`mutated` and the real path emits `rebuilt`, so it would have passed whether
the value was true or false. It now asserts the value.

external-job's refusal already had to name the offending file — that naming is
why the fail-closed variant is survivable rather than a permanent wedge — but
the tests proved it by substring of a prose message. The failure result now
carries offendingPath as its own field and the tests assert it by value. The
human message is unchanged; operators read it.

Array membership is left alone. `phaseIds.includes('99')` and
`result.updated.includes('Completed Phases')` are membership checks on real
arrays, not text matching, and converting them would weaken nothing and clarify
nothing.

* test(#3057): execute acquireStateLock instead of grepping its source

The non-EEXIST lock test asserted on the TEXT of the built .cjs and never
called acquireStateLock. It carried an allow-test-rule: architectural-invariant
exemption to permit that. A source grep proves a literal is present in a file,
not that the behaviour works — it is weaker than a liveness test, which at
least runs the code, and it was the only coverage the fatal-errno path had.

Replaced with tests that inject the errno through fs and assert what actually
happens: a fatal EACCES propagates out of acquireStateLock with zero backoff
sleeps, while EAGAIN/EINTR/EINVAL/EIO/ENOENT/ESTALE/EPERM/EBUSY retry once and
succeed. The exemption is removed and its allowlist entry with it.

One old assertion is deliberately not carried over: it checked the retryable
errnos were expressed as a Set rather than an inline literal. That is a shape
check with no runtime signature; the behavioural tests fail if the code reverts
to the old inline check, which is the regression it was really guarding.

The #3057 lock-body tests move into that same file rather than a new one, which
is what lint-test-file-count asks for and puts every acquireStateLock test in
one place.

* fix(#3057): surface an indeterminate staleness check to its callers

An isolated review caught an inconsistency inside this wave. Two of the three
"add the distinguishing signal" fixes wire through to something a user sees:
git base-branch writes an unverified-fallback diagnostic to stderr, and an
unverifiable worktree surfaces as a W020 finding. The third set
staleCheckIndeterminate on readVerificationStatus's result and nothing read it.

A signal nobody consumes leaves the fail-open exactly as silent as before: the
staleness check could fail and the operator saw precisely what they would see
if the answer were genuinely "not stale". That is the defect this issue exists
to remove, so it is not defensible as scaffolding when its two siblings in the
same change already wire through.

All five callers now surface it, each through the channel it already had rather
than a mechanism imposed uniformly: phase complete adds it to its existing
warnings array and, on the blocked path, as an additive note on the error text;
init and roadmap carry it as a field on output they already emit; the UAT
report carries it without ever gating passed/blockers; workstream inventory
takes an injectable writeDiagnostic mirroring the git base-branch idiom,
because its return shape had nowhere to hang a per-phase field without
rippling the builder's types.

The routing decision is unchanged everywhere. What changes is only that a
caller and an operator can now tell a failed check from a completed one.

That diagnostic carries structured meta rather than being asserted by regex —
the default still writes only the human message to stderr, but tests assert
phaseDir and reason by value. Two earlier assertions in this branch were
converted the same way; this was the last raw-text assertion left.

Also records a scope correction: the completePhaseCore guards now compare
stateReplaceField's result to the body instead of testing truthiness, so a
field whose substitution produced identical text no longer reports as updated.
That is a real behaviour fix, not the signal-only change this file was
described as carrying, and its tests cover both the changed and unchanged
cases.

* test(#3057): bound two heavy subprocesses for a loaded bench, not an idle one

The remote matrix surfaced three failures unrelated to this branch's changes.
All were bad tests, and a re-run would have hidden every one of them.

The reviewer-flags parse block bounded bash -> node -> a full gsd-tools cold
start at 5 seconds. On a bench running thirty thousand tests in parallel that
is not a hang, it is a busy machine. Raised to 30s, matching the convention
sibling suites already use for script invocations, with a comment saying what
the budget covers so nobody tightens it back. Two further copies of the same
5-second spawn in the same file had the identical defect and are raised too —
they were not in the failure report, but they will be next time.

The fragment-propagation test bounded npm run regen:derived — a full build plus
eight generators, the heaviest subprocess in the suite — at five minutes, and
node22 was killed near the end. The captured output proves it: every generator
had written its files and gen:install-tree had emitted all fifteen runtimes
before the kill. Raised to fifteen minutes.

That failure read as `null !== 0`, which says nothing. status null means killed,
not a non-zero exit, and the two want different responses: one is a timeout to
size correctly, the other is a real build break. The assertion now distinguishes
them and names the signal.

Neither test's assertions were weakened and no retry was added. A retry here
would suppress exactly the signal the timeout exists to produce.

* test(#3057): capture fd 1 through the mock tracker, not a raw reassignment

The phase suite reported zero test results on both lanes while running for five
and a half minutes and exiting 1. No assertion text, no stderr, four events for
the whole file: enqueue, start, dequeue, complete. That shape is not a failing
assertion — it is the runner being unable to read the child at all, because it
parses its event stream from the child's stdout.

The cause was the capture helper reassigning fs.writeSync directly. Proven
rather than assumed: a standalone probe patched fs.writeSync and called
process.stdout.write, and the interception fired only when fd 1 resolved to a
FILE, not when it was a pipe. The remote runner captures the event stream to a
file, so a helper that was invisible against a pipe swallowed the reporter's own
output on the bench. That is also why the two sibling suites wired the same way
in this change pass cleanly — they use the mock tracker, the seam io.test.cjs
established for this exact function.

The helper now uses t.mock.method with an explicit restore after each call, so
teardown belongs to node:test rather than a second hand-rolled implementation,
and the interception cannot outlive the one synchronous call it wraps even if
that call throws. Ten call sites thread the test context through; three test
callbacks gained the parameter they lacked.

The three B3 tests are untouched — same assertions, same fault injection. Only
how the context reaches the helper changed.

* test(#3057): capture phase-complete output from a subprocess, not fd 1

Two attempts to make in-process fd-1 interception safe both failed on the
bench. The suite reported zero test results on either lane while exiting 1 —
four events for the whole file — because the runner parses its event stream
from the child's stdout, and process.stdout.write routes through fs.writeSync
whenever fd 1 resolves to a file, which is how the runner captures. Patching
that seam anywhere in a file can therefore destroy the file's own reporting,
and tightening the window only moved the runtime from 326s to 125s without
recovering a single event.

So the interception is gone rather than tuned. The helper now spawns gsd-tools
as a real subprocess and reads stdout the way the OS already gives it to us,
which is what the rest of the suite does. It asserts the command succeeded
before parsing, so a genuine failure can no longer present as a JSON parse
error.

The two fault-injecting tests could not survive that move as written: a
subprocess cannot see a mock installed in the parent. Instead of reinstating
the interception they now produce the fault on disk — the summary artifact is
created as a dangling symlink, so the staleness check's real statSync throws
inside the child. That is a more honest fixture than a mock in any case, since
it is a condition a user's tree can actually be in. Skipped on Windows, matching
the existing symlink precedent in the write-guard suite.

Three further call sites turned out to depend on parent-process writeFileSync
mocks the subprocess could not see. Those call the CJS function directly, which
is what they always wanted — they never needed stdout at all.

* fix(#3057): one name for one signal, one encoding for one distinction

Standards review found four things this branch introduced, all of them
inconsistencies with itself rather than with the repo.

One upstream bit reached its consumers under three names —
verification_stale_check_indeterminate in two modules, the same value with
"stale" dropped in a third, and stderr only in the fourth. Standardised on the
long name wherever it is a field. The workstream inventory keeps its stderr
channel, since its return shape has nowhere to hang a per-phase field without
rippling the builder's types, but it now says the same word for the same thing.

worktree-safety encoded one three-way distinction two ways in a single file: a
named union for a finding's kind, and boolean|null for an inventory entry's
existence. The second is now a named union too.

Two assertions matched human prose because the blocked and non-blocked
completion paths carried no typed field for the signal. Both now assert typed
values. The first round of this fix added the field but left the regex beside
it, which is the banned pattern sitting next to its own replacement; the second
removed it and added an assertion on the reason enum so nothing was lost.

The remaining two were reasoned away before being fixed, and both reasons were
bad. "No typed surface exists" is the condition CONTRIBUTING says to fix by
adding one — it took three lines. "The file already does this dozens of times"
is not licence to add instance number thirty-one; a convention that violates a
documented rule is debt, not precedent.

Vocabulary differing across DIFFERENT modules is left alone: CONTEXT.md rejects
a single shared result envelope, so per-module shapes are precedented, and a
baseline smell does not outrank a documented standard.

A census of every line this branch adds to a test file now finds no regex or
substring assertion on produced prose: 87 strictEqual, 25 ok (all non-empty or
shape guards), 12 equal, 3 throws (all typed err.code predicates), 3
deepStrictEqual, 2 notStrictEqual.

5fd5c81042 test(#3055): add the process seam so a subprocess timeout is expressible as data (#3066)
* test(#3055): add the process seam and route runGsdTools through it

Adds tests/helpers/process-seam.cjs — runNode/runGit/runHook over spawnSync,
each returning a typed discriminated union
{ outcome, exitCode, stdout, stderr, timedOut, signal, killed, code }.
Every call is timeout-bounded; there is no unbounded path.

runGsdTools becomes an adapter over the seam. Its legacy
{ success, output, error, exitCode } shape and retry-once-on-kill behaviour
are preserved byte-identically, so none of its 136 caller files change.

Outcome discrimination was corrected against probed runtime behaviour rather
than assumption: a timeout and a maxBuffer overflow are identical on both
status (null) and signal (SIGTERM), and differ only by code (ETIMEDOUT vs
ENOBUFS). Overflow is therefore classified before timeout. This fixes a live
defect — the previous isKilled() treated an overflow as a kill, retried it for
a second full 60s run, and then reported "host OOM or scheduler contention"
for a child that had merely printed too much.

Also widens the ESLint tests glob from tests/**/*.test.cjs to tests/**/*.cjs,
which brought 31 previously unlinted shared helpers under the same rules their
sibling test files already obey, and fixes the 5 violations that surfaced —
including a bare npm invocation without shell:true in
tests/helpers/emitted-runtime.cjs (DEFECT.WINDOWS-TEST-PORTABILITY), now
routed through the existing portable runNpm helper.

* test(#3055): migrate every local spawn wrapper onto the process seam

Replaces the spawn body of all 25 local runHook/runGuard/runGate definitions
with a call to tests/helpers/process-seam.cjs. Each wrapper keeps its name,
parameter list, return shape and post-processing (JSON parse, ANSI strip, env
sanitising, field extraction) — only the spawn mechanism changes, so no test
assertion moves.

The 4 bash-driven wrappers use the seam's explicit `interpreter` option rather
than a fourth primitive; it is explicit rather than inferred from the file
extension, because guessing an interpreter from a path fails silently when a
script's name does not match its shebang.

Seven wrappers were previously unbounded and now carry an explicit timeout
sized to what each actually runs, not the seam default. Two of those seven
(gsd-write-guard, lint-docs-command-form) were absent from the issue's
inventory entirely and were found by scanning after the migration.

Adds the CONTEXT.md `### Process seam` glossary entry and a CONTRIBUTING.md
reference section covering the three primitives, the discriminated union, and
the two rules the seam enforces.

Scope disclosure recorded in the phase design notes: the issue scoped three
identifier names. A scan for local helpers that spawn AND return the spawn
result finds 113 across 82 names, 71 of them unbounded, plus 122 unbounded
direct git call sites. This change bounds 25 of those. The remaining surface
is the same defect class and is NOT closed by this PR.

* fix(#3055): classify an externally-killed child as KILLED, not EXITED

Blocker found in this branch's own diff, independently confirmed by an
isolated reviewer.

A child killed by an external signal — a genuine bench OOM kill — makes
spawnSync return { status: null, signal: 'SIGKILL' } with NO .error field.
The seam's "no error implies EXITED" rule therefore classified it as a clean
exit, and runGsdTools returned { success: false, exitCode: 1 } without
retrying. That silently defeated the #969 kill-discrimination for precisely
the case it was built for: the old isKilled() fired on `signal != null`,
retried once, then threw a labelled resource-starvation error. A real OOM
would have been reported as an ordinary assertion failure.

Adds a fifth outcome, KILLED, for "no error but a signal is set", and makes
the adapter retry on TIMED_OUT or KILLED — reproducing the old
`killed || signal != null || code === 'ETIMEDOUT'` condition exactly.
SPAWN_FAILED still does not retry (matching the old behaviour, where signal
was null). BUFFER_OVERFLOW still does not retry, which remains a deliberate
divergence: the old code retried it because signal was SIGTERM, burning a
second 60s run on a child that had merely printed too much.

All five outcomes verified against the live runtime rather than assumed:
SIGKILL -> killed, exit 0/7 -> exited, timeout -> timed_out (ETIMEDOUT),
>1MB stdout -> buffer_overflow (ENOBUFS).

* fix(#3055): address standards-review findings on this branch

Three findings from the standards axis of the review, all in this branch's
own diff.

The CONTEXT.md glossary entry this branch introduced was already stale on the
branch's own last commit: it enumerated a 4-member OUTCOME while the code had
5, because the KILLED fix did not update it. That is precisely the drift the
"module changes update Domain-terms" gate exists to catch, so the entry now
lists all five and explains KILLED.

api-coverage-gate-e2e compared an outcome against the raw string 'exited'
rather than OUTCOME.EXITED, the only such outlier; the enum is now imported
and used. A sweep for the other four outcome literals found no further
comparison sites.

Three call sites hand the literal bash flag '-c' to the seam's first
parameter, which the JSDoc described as an absolute script path. Rather than
add a fourth primitive, the contract is corrected to match reality: the
parameter is renamed `target` and documented as the first argv element handed
to the interpreter — normally a script path, but for an interpreter invoked
with an inline program it may be that interpreter's own flag. No behaviour
change.

* test(#3055): assert the cross-platform timeout contract, not the macOS one

The remote runner failed on both Linux lanes (node 22 and node 24, identical)
while the same tests passed locally on macOS. Two assertions encoded a
platform-specific behaviour as a cross-platform guarantee.

When spawnSync times out, macOS preserves the child's partial stdout/stderr;
Linux discards it and returns empty strings. Verified on node v26.5.1 both
ways. The seam passes through whatever spawnSync hands it and cannot
manufacture output that was discarded, so the production code was correct —
the tests were wrong.

Both tests now assert the guarantee the seam actually makes on every
platform: outcome TIMED_OUT, timedOut true, and stdout/stderr always being
strings rather than undefined or a Buffer. The partial-content assertions are
retained behind an explicit process.platform === 'darwin' guard so the macOS
coverage is not lost, and the first test is renamed to say what it now
guarantees.

This is the failure mode the remote matrix exists to catch: local macOS
verification would have shipped it.

* fix(#3055): classify a failed spawn as SPAWN_FAILED, not a timeout

Windows CI caught two defects the Linux matrix could not.

tests/context-predicates-query.test.cjs passes a 32K-char argv value. On
Windows that exceeds the argv limit and spawnSync fails with code
ENAMETOOLONG, signal null, status null. The seam's fallback rule — "otherwise,
status === null implies TIMED_OUT" — swallowed it, so the adapter retried a
spawn that can never succeed and then threw the resource-starvation error. The
old isKilled() returned false for that shape and returned an ordinary failure
result.

TIMED_OUT is now identified positively: code === 'ETIMEDOUT' OR signal is set.
Anything else carrying an error is SPAWN_FAILED, which covers ENAMETOOLONG,
E2BIG, EACCES and ENOENT alike. The signal clause is what keeps a platform
whose timeout errno differs classified correctly, so the greedy catch-all is no
longer needed.

The second defect is a contract regression I introduced and had claimed
otherwise. That same test asserts `typeof r.exitCode === 'number'`, and
toLegacyShape was returning null for BUFFER_OVERFLOW and SPAWN_FAILED, so the
assertion failed on type. The old code returned `err.status ?? 1` on every
non-retried failure path. The adapter now returns 1 again for both, and the
comment claiming "never coerced to exitCode:1, unlike the pre-seam helper" is
retracted: the seam keeps the richer truth (exitCode null plus a distinct
outcome), the legacy adapter keeps the old numeric contract its callers
actually depend on.

Verified on this host: a 4MB argv yields E2BIG -> SPAWN_FAILED; ENOENT ->
SPAWN_FAILED; timeout -> TIMED_OUT; >1MB stdout -> BUFFER_OVERFLOW; SIGKILL ->
KILLED; clean exit -> EXITED.

8f75e27554 fix(#3045): fail closed when an executor dispatch drops its resolved isolation (#3069)
* feat(#3045): deny an executor dispatch that drops its isolation flag

Every isolation gate already resolved correctly. The resolved value then reached
the executor through a prose instruction telling the model to substitute it into
a call the model composes itself, and nothing verified the substitution. When it
was dropped, the executor edited and committed in the user's primary checkout
with no consent and no warning.

A prose backstop would be the same class of artifact as the defect, so this is a
shipped PreToolUse hook on the Agent tool. It fires at the instant of the call
rather than being read once at the top of a workflow, which is the only placement
the model cannot skip.

The guard is inert unless it can positively establish that this is a GSD project,
that the project resolves to harness isolation, and that the dispatch targets an
executor. A non-GSD repo has no invariant to enforce. Where it cannot read the
configuration at all, it denies rather than assuming, with its own reason -- a
guard that cannot verify must not answer safe. A malformed payload allows rather
than throwing.

* feat(#3045): extend the isolation guard to Cursor

Cursor is the second of only two runtimes that resolve harness isolation, so
shipping the guard for Claude alone left half the exposed surface unguarded while
the changeset implied it was covered.

The two runtimes fail differently. On Claude the harness flag is a per-dispatch
kwarg the model must copy into a call it composes, and the defect is that it can
be dropped. On Cursor the flag is --worktree, which applies to the whole session,
and the subagent-start payload carries no isolation field at all. There is no
flag to check, so the guard verifies the effective state instead: whether the
workspace is genuinely running outside the user's primary checkout. That is a
stronger check than the Claude one because it tests reality rather than intent,
and it is commented so nobody later rewrites it into a flag check.

Isolation is established two ways, either sufficient: the workspace resolves to a
linked git worktree, or it sits under the worktree root Cursor manages. The
second matters because a directory Cursor placed there is a legitimate isolated
session even before it becomes a distinct git worktree, where linkage alone would
report no repository.

Detecting linkage required a new primitive rather than the existing context
resolver. That resolver short-circuits on finding a local .planning directory
before it ever compares the git directory to the common one -- and an isolation
worktree normally has its own checked-out .planning. Reusing it would have read a
correctly isolated session as unisolated and denied it, which is the failure
direction that gets a guard switched off. The comparison is now its own
shortcut-free function that the resolver delegates to after its own shortcut, so
existing behavior is unchanged, and the case that would have broken is pinned.

The subagent type is checked before any configuration is read, so an unreadable
config cannot deny a dispatch this guard would never have enforced against.

The input-schema comment on the Cursor hook documented only the fields common to
every event and omitted the ones specific to this one. That omission cost a
halt during this work; it now documents both.

* fix(#3045): enforce the resolved dispatch decision, not the host capability

The guard keyed on the registry's dispatch.isolation, which says only that a
runtime is CAPABLE of harness worktrees. The decision that actually governs a
dispatch is the one the workflow resolves after gating, and that legitimately
comes out as sequential in three documented cases: a project setting
use_worktrees false, a per-plan submodule intersection, and the base-check
auto-degrade. The workflow tells the model to omit the flag in exactly those
cases, and the guard was denying every one of them.

The third case matters most. The preceding fix made the base-check degrade on
git timeouts and a missing git binary, where it had previously answered "safe".
That correction is right, and it means a transient hang now degrades to
sequential far more often than before -- so the two changes composed into a trap
where the workflow behaved exactly as designed and the guard blocked it.

The workflow already resolves isolation in shell, deterministically, which is
what makes it a trustworthy source in a way the model-authored call is not. It
now records that resolved value through a dedicated verb, and both guards read
it first. A fresh record is authoritative, so sequential dispatches pass
untouched. Absent or stale, the guards fall back to the capability check
combined with the project's use_worktrees setting, which still covers the case
that never reaches the workflow.

Also widened the matcher to accept Task alongside Agent, since a host that names
the tool Task would otherwise leave the guard silently inert while implying
coverage; stopped assuming Claude when no runtime is declared, which is the
shipped default and would have demanded a Claude-only argument elsewhere; and
made a non-git project inert rather than denied, since advising a worktree
session is not actionable without a repository.

The original diagnosis never modeled sequential mode as legitimate. That
omission is what let this through, and it is now recorded there.

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

* fix(#3045): record at resolution and bind the record to its dispatch

Two independent reviews converged on the same failure: the guard was fail-open in
a default install, so it did not catch the defect it exists to catch. A shipped
project carries no runtime key, which made "runtime not confidently known" the
common case rather than a corner one. A record asserting that isolation was
required but carrying no flag then fell through to a capability lookup that
answered "none", and the dispatch was allowed. The flag itself only arrived from
a second shell block -- the same block a model dropping the argument would also
skip. A test had pinned that behavior as intended.

The record is now written by the resolver, as an unavoidable consequence of
asking for the value, rather than by a step the model is told in prose to go and
run. A guard against a prose-carried value cannot itself depend on prose. Mode,
flag and identifiers are written together and atomically, so the flagless window
is gone, and a record asserting isolation with no resolvable flag now denies
instead of degrading. Runtime is also resolved from the installer's own recorded
default, which makes confident resolution the normal case.

The per-plan submodule gate degrades after the phase-level decision and never
re-recorded, so a plan that legitimately ran sequentially was denied against a
still-fresh phase record. It now records its own, scoped to the plan.

A record also authorized any dispatch for four hours. One phase degrading to
sequential could silently license an unisolated dispatch in the next. Records
now carry phase and plan, the guards require them to match, and the window is
minutes rather than hours -- the resolver rewrites it before every dispatch, so
a long window bought nothing and only widened the hole.

The flag validator rejected any value beginning with two dashes, which is exactly
the form Cursor and Windsurf declare, so their real value could never have been
stored. Writer and reader also derived the record path differently and diverged
inside a linked worktree without local planning state.

The predictable path remains a way to silence the control without leaving a trace
in the diff. It grants no access an agent with shell does not already have, so it
is documented as accepted rather than redesigned around.

* fix(#3045): correct the staleness boundary and unmask a vacuous parity test

The remote runner returned twenty failures. One was a real production defect the
boundary case existed to catch: a record whose age exactly equalled the staleness
window was treated as fresh, so it stayed authoritative for one tick past its own
expiry. Freshness is now strictly inside the window.

The parity test meant to stop the two guards' executor lists from drifting could
never have failed. Its project fixture was a bare directory rather than a
repository, so the non-git inert branch answered before the executor list was
ever consulted. It asserted agreement it never actually measured. The fixture is
now a real repository, like every sibling in the file.

A test also asserted that Windsurf declares the worktree flag. It does not --
Windsurf resolves to no isolation by design, having no named concurrent dispatch
to isolate. The test claimed a registry fact that was never true, and a comment
in the resolver repeated it. Both corrected, and the test now proves what it
should have all along: that the parser accepts any bare flag value, rather than
one runtime's supposed value.

The new guard was missing from the bundled-hook whitelist, which is the surface
that decides what actually ships, and the per-plan gate had gained calls to the
launcher without the preamble those calls require. The changeset carried
parenthetical product descriptions the purity rule forbids.

* test(#3045): make the guard tests hold on Windows

Two tests redirect HOME to control where the installer-persisted runtime default
is read from. Node resolves the home directory from USERPROFILE on Windows and
never consults HOME, so both silently read the real runner profile, found no
recorded runtime, and asserted against a project the hook had not recognised. The
production code was already correct in asking the platform rather than the
variable; only the tests were wrong to assume one variable answers everywhere.
The helpers now mirror the override onto both.

The symlink spoofing test also created a directory symlink unconditionally, which
needs elevated privileges on Windows. It survived on this runner, but it would
fail on any host without them, so the creation is now attempted and the test
skips explicitly when it cannot be done -- a bare return would have counted as a
pass and hidden the gap.

Skipping alone would have left the platform uncovered, so the behaviour it proves
is now also driven in-process through an injected realpath, following the seam
already used for the clock. That case no longer depends on privileges at all, and
the end-to-end test keeps its original assertions wherever symlinks work.

24066e536e fix(#3050): fail closed when a worktree guard cannot verify safety (#3054)
* fix(#3050): fail closed when a worktree guard cannot verify safety

Three places answered "safe" when they had not actually checked.

The base-divergence gate held the clearest evidence against itself: within one
function, an unresolvable fork ref correctly degrades, while an unresolvable
HEAD twenty-five lines earlier returned "proceed". Because a timeout collapsed
into the same branch as "not a git repository", a locked index or a stalled
mount produced a green gate that had never resolved the fork base -- and that
value decides parallel versus sequential dispatch.

Timeouts are now distinguished from a genuine absence of a repository. A
timeout degrades with its own reason and message; not-a-git-repo keeps today's
non-degrading behavior, because there is no worktree concern there. The same
conflation in worktree-context resolution is surfaced rather than silently
falling back to the current directory.

Worktree creation's root confinement was opt-in: omitting the root skipped the
check entirely, leaving only the leading-dash and parent-segment guards. The
sole caller always passed it, so nothing was exploitable -- it is now mandatory
so a future caller cannot inherit an unconfined path by forgetting.

The timeout predicate was checked against what Node actually emits on a
spawnSync timeout, not only against the fixtures, so it cannot be a guard that
fires solely in tests.

Coverage is deliberately behavioral. The existing worktree suites -- 134 tests
across two files -- require no production module and call no production
function; they assert against prose and would pass with the implementation
deleted. That is how three fail-open guards survived in a heavily-tested
module, so the new tests drive the real resolvers through an injected git seam,
with five of them pinning the paths that must NOT change.

One existing test asserted the opt-in confinement behavior and was rewritten
rather than left green against the corrected code.

* test(#3050): stop a CLI exit code leaking into the test process

The runner reported the new file as failed while the file's own summary said
nine tests passed and none failed. That signature is a non-zero process exit
after a green run, not a failing assertion.

Cause: the confinement test calls the worktree-create command function directly,
and that function sets process.exitCode on its failure path as a CLI would. In
process, that exit code became the test file's own exit status.

The sibling suite already guards this with a save/restore wrapper and a comment
naming the hazard; the new file simply did not follow the convention. It does
now.

Root cause is in the test, not the production code -- setting an exit code is
correct behavior for a command entry point, and the existing convention exists
precisely because tests call these functions in process.

Verified by exit-code and active-handle probes rather than by re-running: exit
was 1, is now 0, with zero lingering handles and all nine tests still passing.

97f2af29da fix(#2852): isolate wave-cleanup blocks to their own entry (#3009)
* test(#2852): add failing-first regression coverage for wave-cleanup isolation

Adds the #2852 test matrix to executeWorktreeWaveCleanupPlan: per-entry
block reasons must isolate to the blocked entry instead of aborting the
rest of the wave, and a deletion must only block when another wave
member's branch still touches the deleted path. These fail against the
current implementation (RED) — the fix lands in the next commit.

* fix(#2852): isolate wave-cleanup blocks to their own entry and scope the deletions guard to real dependents

executeWorktreeWaveCleanupPlan aborted the rest of a cleanup wave on the
first blocked entry (branch_mismatch, base_mismatch, worktree_dirty,
merge_failed, etc.), dumping every remaining entry into `pending`
untouched instead of evaluating it. Every per-entry block reason now
isolates via `continue` instead of `break` + bulk pending push. The one
exception is a failed --no-ff merge, which can leave repoRoot itself
mid-merge: that path now attempts `git merge --abort` and only halts the
remaining wave if the abort itself fails (an unrecoverable repo-level
failure), matching every other block reason's isolation.

The `branch_contains_deletions` guard also blocked any deletion
unconditionally, even one nothing else in the wave depends on (the
reported repro: folding a test file into a sibling and deleting the
original). It now blocks only when another wave member's branch still
touches the deleted path — computed lazily per wave so a run with no
deletions pays no extra git call, and fails closed (still blocks) when
a sibling's diff cannot be determined.

* fix(#2852): eagerly cache each entry's own diff to fix an ordering bug in the deletions-overlap check

The deletions cross-entry overlap check (previous commit) computed
each "other" entry's touched-files set lazily, the first time some
later entry's overlap check needed it. That is wrong: once an entry
has already been merged earlier in the same loop pass, its branch
becomes an ancestor of HEAD, and `git diff --name-only HEAD...branch`
silently collapses to empty. A dependent entry that appears BEFORE the
deleting entry in the manifest (and has therefore already merged by
the time the deletion check runs) would be missed, letting a
genuinely-depended-on deletion through undetected — a live violation
of the negative-space acceptance criterion, caught by /code-review's
Spec-axis before this shipped.

Fixed by populating each entry's touched-files cache eagerly, during
that entry's own turn in the loop, immediately before its own merge
attempt (the only step that can move HEAD) — so every entry's diff is
captured before it could possibly have been merged, regardless of
manifest order. Adds a regression test reproducing the exact broken
ordering (dependent merges first, then a later entry tries to delete
the file it depends on).

* refactor(#2852): extract shared git name-only line parser

/code-review's Standards axis flagged duplicated parsing logic:
`stdout.split('\n').map((l) => l.trim()).filter(Boolean)` appeared at
both the per-entry deletion list and the cross-entry touched-files
cache added by this fix. Extracted into parseGitNameOnlyLines(), used
by both call sites, so the two can't silently drift apart.

* revert(#2852): scope the fix to wave-isolation only, restore unconditional deletions guard

#2852's own triage comment explicitly deferred the deletions-guard
policy question as a separate product decision ("Policy/enhancement
ask, not a defect ... Out of scope: deciding or implementing an
opt-in mechanism for intentional deletions"). All four of the issue's
actual acceptance criteria concern wave isolation only. The prior two
commits on this branch built a cross-entry deletion-dependency
heuristic that substituted a derived judgment for that deferred
product decision — out of scope for a confirmed-bug fix.

Reverts: getEntryChangedFiles, touchedFilesCache, the overlapUnknown
fail-closed branch, parseGitNameOnlyLines, and the eager per-turn
cache-population call. `branch_contains_deletions` now blocks
unconditionally again (byte-identical trigger condition to pre-fix);
the only change is `continue` instead of `break` + bulk `pending.push`,
same as the other 7 block reasons.

Keeps: the full wave-isolation fix (all 8 sites) and the merge_failed
/ git merge --abort recovery-and-carve-out, both squarely inside the
issue's actual acceptance criteria.

The deferred opt-in-for-intentional-deletions decision is filed as
#3003, citing #2852's triage as origin.

* refactor(#2852): extract blockEntry() helper to remove duplicated block-assembly across 8 sites

/code-review's Standards axis flagged the repeated
"result.status='blocked'; result.reason=...; result.stderr=...;
results.push(result); ok=false;" shape at every one of the 8 per-entry
block sites this fix touches. Extracted into blockEntry(), called at
each site; each call site still owns its own continue/break decision.
No behavior change.

* fix(#2852): check actual repo state instead of git merge --abort's exit code

The merge_failed recovery path decided "genuinely unrecoverable, halt
the wave" based on whether `git merge --abort` itself exited
successfully. That is not a reliable signal: git refuses many merges
(e.g. "your local changes would be overwritten by merge") WITHOUT
ever creating a MERGE_HEAD, in which case repoRoot's tree was never
touched — but `git merge --abort` still fails with "There is no merge
to abort (MERGE_HEAD missing)?" in that exact safe case. Trusting
that exit code alone misclassified an ordinary per-entry merge
failure as a repo-level one and stranded the rest of the wave — the
exact defect #2852 exists to fix, reintroduced through the recovery
path (caught in review).

Fixed by checking repoRoot's actual state directly via
`git rev-parse --verify -q MERGE_HEAD` after the abort attempt:
MERGE_HEAD present means genuinely still mid-merge (unrecoverable,
halt); absent means safe (isolate and continue), whether because no
merge state was ever entered or because abort successfully cleared
it. An unexpected git error or timeout degrades to the conservative
"still mid-merge" answer rather than throwing or guessing.

Rewrites the "unrecoverable merge_failed" test, which previously used
the safe "There is no merge to abort" string as its unrecoverable
example — that pinned the defect as correct behavior. Adds the
missing case: an ordinary merge_failed that never entered a merge
state must not abort the wave.

* test(#2852): cover repoRootStillMidMerge's fail-closed branches

/code-review flagged that the two conservative fail-closed branches of
repoRootStillMidMerge (a timeout on the post-abort MERGE_HEAD check,
and an unexpected non-0/1 exit code such as a fatal git error) had no
test coverage — exactly the branches most likely to hide a mutation
survivor (e.g. a flipped `timedOut` check or a flipped final `return
true`). Adds both cases: each must halt the wave (fail closed) rather
than assume repoRoot is safe when its state cannot be verified.

a8b40fa53f fix(#2547): fail closed on crashing and path-shadowing Kimi payloads (#2595)
* fix(#2547): fail closed on a malformed Kimi edit list in normalizeKimiPayload

`normalizeKimiPayload` rebuilt old_string/new_string with
`String(e.old ?? '')`. `??` guards the value, not the dereference, so a
nullish entry in a Kimi `edit` list threw a TypeError at the top of the
handler, before any tool dispatch. Each guard's outer
`catch { process.exit(0) }` swallowed that crash and emitted the same exit
code as "nothing to report" — turning a should-BLOCK call into a silent
allow.

Two hard blocks were bypassable:

  * gsd-worktree-path-guard's cross-git-root write block (#260) — a
    StrReplaceFile write whose path resolves to a different git root is
    correctly blocked with a well-formed edit list, and silently allowed
    with `edit: [null]`.
  * gsd-workflow-guard's force-add block on agent-* branches — a Shell
    payload carrying a spurious `edit: [null]` field walks past it. The
    Bash path never reads `edit`; the field only has to be present to
    trigger the crash.

Fixed with `e?.old` / `e?.new`, landed identically in all five copies so
tests/kimi-guard-normalization-parity.test.cjs's byte-identity assertion
still holds.

The crash boundary is nullish specifically, not "non-object": `('x').old`
and `(7).old` are legal reads yielding undefined, so string/number entries
never threw. Both are kept as controls proving the fix did not change
their behaviour.

Regression coverage is folded into the owning suites per CONTRIBUTING.md
(no new bug-* files). Negative-controlled: the nullish cases exit 0
against pre-fix guards and exit 2 after, with positive controls (the
equivalent well-formed payload blocks) and negative controls (in-worktree
writes and benign commands still pass) alongside.

Refs #2547

* test(#2547): exercise the production Kimi payload shape in read-guard tests

The `#2304: Kimi tool vocabulary engages the read guard` cases send
payloads with no `session_id`, and runHook injects none. A live Kimi turn
always carries one — kimi-cli's hooks/events.py `_base()` sets it
unconditionally, and soul/kimisoul.py calls `set_session_id()` at the top
of every turn before tool dispatch, so the ContextVar's `default=""` never
reaches a tool call.

gsd-read-guard treats any non-empty `data.session_id` as "Claude Code
already enforces read-before-edit, skip" (#2520). So the advisory those
tests assert fires only for a shape production never sends: the tests were
green, and the guard was dormant on Kimi. A sibling #2520 case in the same
file asserts the skip when `session_id` IS present — both passed, and the
production shape hits the skip.

Two changes, test-validity only:

  * Retitle the #2304 block to say what it proves — the tool VOCABULARY is
    normalized through to the Write/Edit branch — with a comment warning
    not to read it as production evidence.
  * Add a #2547 block asserting behaviour against the production shape
    (session_id populated), including a case that pins the delta directly:
    the same payload fires without session_id and is silent with it.

The #2547 block characterizes a known gap; it does not endorse it.
Redesigning how the guard discriminates runtimes is explicitly out of
scope for #2547. If a later change makes the advisory fire on Kimi these
tests are supposed to fail — update them then rather than dropping the
coverage.

Refs #2547

* docs(#2547): scope the Kimi guard-engagement claim to what Kimi enforces

#2518 engaged the guards' Kimi matchers and the release notes describe the
result as "All seven guard hooks now engage on Kimi", singling out the
prompt-injection read scanner as "the security-relevant guard" taken "from
silently dormant to engaged". That is not achievable for the scanner at
the emit layer.

gsd-read-injection-scanner.js is a PostToolUse hook, and kimi-cli's
dispatch never inspects PostToolUse hook results: src/kimi_cli/soul/
toolset.py awaits PreToolUse and honours `result.action == "block"`, but
fires PostToolUse via asyncio.create_task() and returns the ToolResult
without awaiting it — the done_callback only retrieves the task's own
exception. So no output shape the scanner emits can block or flag a Kimi
tool call, and `security.injection_blocking` cannot take effect there.
Reshaping the scanner's output would not change this; the enforcement gap
is in kimi-cli's PostToolUse handling, which is out of scope here.

This corrects the claim rather than the code — there is no gsd-core emit
fix that would make it true:

  * .changeset/2304-kimi-guard-tool-name.md — the fragment is unreleased,
    so it would otherwise ship this as a CHANGELOG security claim.
    Headline narrowed to "normalize Kimi's payload shape" and a scope
    paragraph added naming what actually blocks on Kimi (the two
    PreToolUse blocks) versus what cannot.
  * docs/migration/kimi-to-kimi-code.md — the scanner was listed under
    "Every GSD `PreToolUse` guard"; it is PostToolUse. Corrected, and the
    "What about the dormant guards?" section now splits enforceable from
    not-enforceable instead of saying Phase 0 "fixed all seven".
  * hooks/gsd-read-injection-scanner.js — the same scope note in the
    file's own Kimi rationale comment, where the next contributor to touch
    the normalization will actually read it. Comment only; the shared
    normalization block is untouched and byte-identity still holds.

* chore(#2547): regenerate golden install-parity fixtures for the guard fix

The golden install-parity fixtures record a content hash per installed
file, so changing the five guard hooks changes their hashes across every
runtime's fixture. Regenerated with the full sweep (build, gen:golden,
size:baseline) rather than a single generator — running gen:golden alone
leaves tests/workflow-size-baseline.json stale and loses CI jobs to a
regeneration that looked complete.

The size baselines came out unchanged (no workflow or agent bodies
touched) and the hash delta is confined to exactly the five guards:
gsd-prompt-guard, gsd-read-guard, gsd-read-injection-scanner,
gsd-workflow-guard, gsd-worktree-path-guard.

Refs #2547

* fix(#2547): guard the String() coercion in normalizeKimiPayload too

Found by adversarial review of the first commit, then reproduced against
pristine next: `e?.old` closes the nullish dereference but leaves a second
route to the same crash-to-allow.

`{"toString": null}` is valid JSON, and coercing it throws
`TypeError: Cannot convert object to primitive value` — so an edit entry
that IS a well-formed object still crashes normalization, still lands in
the outer `catch { process.exit(0) }`, and still downgrades a should-BLOCK
call to a silent allow. Confirmed on both hard blocks:

  {"tool_name":"Shell","tool_input":{
     "command":"git add -f secret.env",
     "edit":[{"old":{"toString":null},"new":"x"}]}}      -> exit 0 (was)

  {"tool_name":"StrReplaceFile","tool_input":{
     "path":"<main-repo>/src/index.ts",
     "edit":[{"old":{"toString":null},"new":"x"}]}}      -> exit 0 (was)

Both exit 2 now.

The coercion is wrapped rather than replaced with a `typeof === 'string'`
test on purpose. Degrading only the non-coercible entry keeps
stringification identical for every value that CAN coerce — numbers,
arrays, plain objects — which matters because gsd-prompt-guard scans
new_string for injection patterns, and a `typeof` test would silently stop
scanning content that reaches that scan today (e.g. `new: ["ignore all
previous instructions"]` currently stringifies and is scanned). Verified:
zero behaviour change across string, number, bool, null, array-of-strings,
nested array, plain object and `__proto__`-keyed input; only the throwing
case changes, from crash to ''.

Regression cases are negative-controlled against the previous commit: the
four new coercion-trap tests fail with only the `e?.old` fix in place and
pass with this one.

Refs #2547

* chore(#2547): cover the String() coercion vector in the changeset

The release note described only the nullish-dereference route. Both routes
reach the same fail-open, so both belong in the changelog entry, along with
why the coercion is wrapped rather than type-tested.

Refs #2547

* chore(#2547): point the changeset fragment at the real PR number

The fragment has to exist before `gh pr create` runs, so it carried the
issue number as a placeholder. Corrected to 2595 now that the PR is open.

Refs #2547

* fix(#2547): make Kimi's `path` authoritative over a model-supplied `file_path`

normalizeKimiPayload copied Kimi's `path` into `file_path` only when
`file_path === undefined`, so any `file_path` the model chose to include won
outright. Every guard reads `file_path`; kimi-cli executes on `path`. The guard
therefore inspected one file while the write landed on another.

This bypass needs no crash. A payload pairing a cross-root `path` with a
spurious `file_path: ""` left gsd-worktree-path-guard reading an empty string
and exiting 0, while the identical write without the extra key blocked — the
same cross-root write the #260 block exists to catch. The shadowing also
preserved a non-string `file_path` (`[]`), which threw inside that guard's
path.isAbsolute() and reached its outer `catch { process.exit(0) }`: the same
crash-to-allow the rest of #2547 closes, reached through the guard's own read
rather than through normalization.

Reachability is not speculative. kimi-cli's soul/toolset.py json-parses the
model's raw tool arguments and passes that dict verbatim as tool_input to
PreToolUse, performing typed validation only later inside tool.call() — after
the hook has already decided. So the model controls extra keys in tool_input at
the moment the guard runs. kimi-cli's file tools carry no `file_path` field at
all (src/kimi_cli/tools/file/write.py, replace.py), so a `file_path` in a Kimi
payload is always model-supplied.

`path` now wins outright. Overwriting can only ever narrow what a guard inspects
to the path that will actually be written, so it cannot under-block.
Normalization returns early for non-Kimi tool names, so the native Claude Code
contract (file_path governs) is untouched.

Landed identically across all five inlined copies; the byte-identity assertion
in tests/kimi-guard-normalization-parity.test.cjs enforces that.

* test(#2547): cover the file_path-shadowing bypass in the #260 guard suite

Four cases, each exiting 0 (bypass) against the pre-fix guards: a spurious
empty-string file_path, an in-worktree decoy file_path, and non-string
file_path values (array and object) that additionally crashed
path.isAbsolute() into the outer catch.

Two controls that are not bypass cases and matter as much:

  - an in-worktree write carrying a cross-root DECOY file_path must still exit
    0. Pre-fix this blocked, because the decoy won; the guard now follows the
    path kimi-cli executes on in both directions, so the fix narrows what is
    inspected without over-blocking.

  - a native Claude Edit (no `path` field) must still block on file_path alone.
    normalizeKimiPayload returns early for non-Kimi tool names, and this pins
    that the non-Kimi contract did not move. It passes both pre- and post-fix
    by design.

Negative-controlled: run against the pre-fix hooks, the four bypass cases and
the decoy control fail, and the native-Claude control passes.

* test(#2547): back the totality claim with property tests over fc.anything()

This PR claims the fix "makes normalization total over the inputs JSON can
express" — a for-all guarantee — while the tests backing it are example-based,
each shape added reactively after a crash was found by hand (the String()
coercion trap was itself found by adversarial review after the first commit
shipped). Example-based tests cannot substantiate a for-all claim; they record
the counterexamples someone happened to think of.

Four properties over fc.anything(), which is exactly the JSON-expressible
domain the claim names:

  (a) totality over any tool_input
  (b) totality over any edit list — the crash surface both #2547 fixes targeted
  (c) `path` always wins over any model-supplied `file_path` (the review blocker
      invariant: a guard reading file_path can never be aimed at a file other
      than the one kimi-cli writes)
  (d) a non-Kimi tool_name passes through untouched — the native Claude contract

normalizeKimiPayload is inlined per hook with no runtime binding, so there is
nothing to require. The block is extracted from hook source and evaluated via
the SAME extraction contract kimi-guard-normalization-parity.test.cjs uses, so
a source edit that breaks one breaks both instead of silently testing a stale
block. An extraction floor test fails loudly if the extraction yields a no-op.

Non-vacuous, and checked rather than assumed: against pristine pre-#2547 `next`,
(a), (b) and (c) all FAIL and (d) passes. (a) needed the fix that makes it
meaningful — a bare fc.anything() for tool_input passed even against the live
defect, because arbitrary generation essentially never invents the `edit` key
the crash lives behind, so the generator is biased onto the keys normalization
actually reads and unioned back with unbiased input.

* chore(#2547): cover the shadowing vector in the changeset and regen goldens

Golden install-parity churn is hash-only, on exactly the five hook files this
round changed. gsd-phase-boundary.sh is deliberately unchanged.

* test(#2547): make the property test able to kill the coercion mutant

Review Major 1: the generative test added to stop the NEXT counterexample
could not kill the one it was written for. Reproduced the reviewer's matrix
independently — against the shipped generator, a mutant reverting `editText`
to the unguarded `String(v ?? '')` passed all four properties.

Cause, confirmed by measurement: the edit-array ENTRIES were bare
`fc.anything()`, which essentially never invents an `old`/`new` key, so
`e?.old` was always undefined and `String(undefined ?? '')` never coerced
anything. That is the same vacuity the file's own comment describes one level
up, reproduced one level down.

The review's prescribed fix — bias the entry onto `{old, new}` — is necessary
but NOT sufficient, and this is the part worth recording: measured over 20,000
draws, bare `fc.anything()` yields a non-coercible value 3 times (0.015%). At
`numRuns: 200` an `old` key holding a hostile value essentially never
co-occurs, and the mutant survives the entry bias too. Both levels need
biasing — the entry onto the keys normalization reads, and the VALUE onto the
shape that actually throws.

`{"toString": <non-function>}` is that shape and stays inside the
"JSON-expressible" domain the claim names (JSON.parse produces it verbatim);
`fc.anything({withNullPrototype: true})` would also kill the mutant but widens
the domain past what the PR asserts, so it is not used.

Verified: M1 now dies at every seed tried (1/7/42/99/4242/31337, failing
within 3-31 cases) while HEAD stays green at all of them.

Also closes three coverage gaps the review listed as nits — properties (e)
totality over any JSON value as the WHOLE payload, (f) the tool_output →
tool_response mapping (including that an existing tool_response is not
clobbered), and (g) an empty edit list reconstructing nothing.

Property (e) required a one-line fix in the normalizer itself: `JSON.parse
('null')` is null, and null/primitive payloads threw on the `data.tool_name`
read — falsifying the "total over the inputs JSON can express" claim. Harmless
in practice (the throw landed in the same fail-open catch as the exit 0 it now
takes deliberately), but the claim should be true as stated. Landed
byte-identically across all five copies.

Refs #2547

* fix(#2547): make old_string/new_string authoritative, not merely defaulted

Review Major 2: the shadowing class the prior round's BLOCKER closed for
`file_path` survived one field over. `old_string`/`new_string` were still
reconstructed only `if (input.<field> === undefined)`, so a model-supplied
value won.

The argument for making `path` authoritative applies verbatim here.
kimi-cli's StrReplaceFile schema is `path` + `edit` only
(src/kimi_cli/tools/file/replace.py @ 4a550ef) and carries no
`old_string`/`new_string` at all, so either key appearing in a Kimi payload is
always model-supplied — exactly like `file_path`.

Verified end-to-end against the reviewer's payload: a cross-root write
carrying `new_string: ""` alongside an injected `edit[].new` left
gsd-prompt-guard reading '' and returning at its `if (!content)` guard, so the
injection advisory never fired and the reconstructed content was never
scanned. `new_string: null` behaved identically. Negative-controlled: both
produce empty output against pre-fix source and fire the advisory after.

Chose unconditional reconstruction over the offered `typeof` alternative
deliberately. A type test closes `""`/`null` but leaves the interesting case
open — a benign NON-EMPTY decoy (`new_string: "chore: tidy"`) shadows just as
effectively and passes any type test. The new suite includes that case
specifically; it is what discriminates between the two candidate fixes.

Also pins the kimi-cli SHA in the authoritative-path comment, as requested —
it cited file names with no version while the issue pins 4a550ef.

Landed byte-identically across all five inlined copies; the parity test's
byte-identity assertion holds.

Refs #2547

* fix(#2547): close the non-string file_path crash-to-allow at every read site

Review Major 3: the crash-to-allow was closed only as a side effect of `path`
masking the bad value, while the changeset read as though it were closed
outright. Confirmed both of the review's reachability claims: `[]`/`{}`/`42`
are truthy, survive the `!rawFilePath` early-out, and throw inside
path.isAbsolute() into the outer `catch { process.exit(0) }`; and normalization
returns early for native Claude Code payloads (KIMI_TOOL_NAMES has no 'Edit'
entry), so `{"tool_name":"Edit","tool_input":{"file_path":[]}}` reached it
untouched — this guard's original #260 surface.

Reproduced on a real fixture: string cross-root path exits 2, the identical
payload with `[]` or `{}` exits 0.

Swept the class rather than the instance. Five more untyped read sites across
four other hooks, each one line from a type-strict or method-dependent call.
Census of what each can actually do:

  gsd-worktree-path-guard.js:173  BLOCKS  -> live bypass (the review's finding)
  gsd-prompt-guard.js:128         scanner -> silenced the injection scan, the
                                             same outcome as Major 2 by another
                                             route; verified empirically
  gsd-workflow-guard.js:206       advisory only (its exit-2 is the Bash
                                             force-add path, which reads
                                             `command`, not `file_path`)
  gsd-read-guard.js:141           advisory only
  gsd-read-injection-scanner.js:213  advisory only
  gsd-windsurf-pre-write.js:75    ALREADY TYPED — the shape adopted here

All six now read typed. The workflow-guard site keeps its truthiness fallback
(`(typeof x === 'string' && x) || ...`) because a bare type test would let an
empty `file_path` shortcut the `path` fallback.

Also declares one swept hit NOT fixed: `gsd-workflow-guard.js:175` reads
`command` untyped on a genuinely blocking path. Same shape, but not
exploitable — unlike file_path/path there is no second field carrying the
executable value, so a non-string command cannot smuggle a real `git add -f`
past the block. Left alone rather than widen this PR into the Bash path.

The regression gate is a SOURCE-level invariant, not a behavioural one, and
that is deliberate: the fixed read and the crashing read are black-box
identical — both end at exit 0, one via the catch and one via the early-out.
A test asserting exit 0 on a non-string payload passes against the unfixed
code, which is the same false-green the review flagged in the existing
`['non-string file_path (array)', []]` cases. Repeating it one level up would
be no better. tests/kimi-guard-typed-payload-reads.test.cjs fails if any hook
regresses to an untyped read (negative-controlled: it reports all five
pre-fix sites with correct file:line).

The behavioural cases requested — non-string file_path with NO `path` key —
are added to worktree-safety.test.cjs and labelled honestly as documenting the
explicit fail-open rather than detecting a revert.

Also states the relative-path premise (review Minor 5) at the early-out that
depends on it: "always safe" holds only while every runtime reaching there
resolves relative paths against the tool CWD. Claude Code satisfies it by
requiring absolute paths; kimi-cli's resolution behaviour is NOT verified here
and is recorded as an unverified premise rather than an asserted bypass.

Refs #2547

* docs(#2547): correct the changeset's closed-claim and fold the misattributed note

Review Major 3 also flagged the fragment: it said the non-string vector "threw
inside that guard's path.isAbsolute() ... `path` now wins outright", which
reads as closed when it was closed only conditionally. Rewritten to state what
is now true — closed unconditionally at all six read sites — and extended with
the Major 2 finding.

Review Minor 6 (the #2547 scope note living in a `pr: 2518` fragment) turns out
to understate the problem. Rendering the changelog and re-parsing it shows the
note is not merely misattributed — it is DROPPED. serializeChangelog emits each
fragment as a single `- ` bullet, and parseChangelog terminates a bullet at the
first non-continuation line, so everything after a blank line is lost on
re-parse. Audited all 44 fragments: exactly one was lossy —
2304-kimi-guard-tool-name.md, losing 656 of 1730 characters, i.e. precisely
that second paragraph. Folding it into this PR's fragment fixes the
attribution and the silent loss together; all 44 now round-trip losslessly.

That same mechanism is why the remaining nit — reformat this fragment's
~2,000-character paragraph for readability — is NOT applied. A paragraph break
or a bullet list would silently truncate the entry at the first blank line
(verified for both). The single-paragraph form is load-bearing under the
current serializer, not an authoring preference. Worth its own issue; noted in
the PR thread rather than worked around here.

* chore(#2547): regenerate golden install parity after rebase onto next

Rebased onto `next` @ 9138271b (the PR had gone BEHIND by 20 commits; the
review's closing nit asked for it). The replay was CLEAN — no conflicts — and
that is exactly why this commit exists.

These fixtures are one key per installed file, so when the PR pins five hook
entries and the base rewrites others', the two edits land on different lines of
the same JSON. Git merges them silently and correctly AS TEXT while attesting
nothing about whether the merged hashes are still valid. Verified rather than
assumed: per-key equivalence against the old base showed the base had moved 22
of the 27 keys this PR pins in every runtime fixture, and
tests/golden-install-parity.test.cjs failed on 10 runtimes immediately after the
clean rebase. A push without this regen would have gone out red.

Regenerated with `npm run build && npm run gen:golden` under a throwaway
HOME/CLAUDE_CONFIG_DIR (the generators invoke the installer); live-profile
canary clean before and after.

Contamination check: every key differing from the base's committed fixture
resolves to a file this PR actually touches — the five guard hooks, under both
the `hooks/` and `.kimi/hooks/` install layouts, and nothing else. Derived from
the PR's changed-file set rather than a feature-name filter, which is what
would have mislabelled the registration surfaces.

Size baselines re-checked and NOT regenerated: this PR moves no workflow or
agent, and the base's own baselines are current (agent-size-budget,
workflow-size-budget, workflow-size, update-size-baseline all green).

Refs #2547

* chore(#2547): allowlist the field-shadowing security test in the injection scan

The new regression suite tripped the repo's own prompt-injection scan — a test
for the injection scanner setting off the injection scanner.

The fixture has to be a real injection phrase for the test to assert anything:
it is precisely the content gsd-prompt-guard must still scan once a
model-supplied `new_string` can no longer shadow the reconstructed
`edit[].new`. Weakening it to a benign string would make the suite vacuous.

Allowlisted rather than obfuscated, because that is this repo's established
convention for the class — tests/read-injection-scanner.security.test.cjs,
tests/security-prompt-injection.security.test.cjs,
tests/prompt-injection-scan.security.test.cjs and four others carry real
payloads as test DATA and are listed for exactly this reason. Splitting the
literal to dodge the grep would work but would make this one file inconsistent
with its five peers and leave the next reader wondering why.

Verified with the CI invocation itself (`scripts/prompt-injection-scan.sh
--diff upstream/next`): 26 files scanned, 0 findings. The .cjs codebase scan
does not cover tests/ and is unaffected (73 tests green).

6ad30f74b6 feat(#2584): Phase 3 — scheduler consumer + isolation adapters (#2635)
Final phase of #2584 (ADR-1239 Codex-binding amendment). execute-phase now negotiates dispatch.isolation and dispatches through the matching adapter, so a wave's independent plans run concurrently on six runtimes instead of one — with no runtime=== branch in the scheduler.

harness-worktree passes the host's declared isolation flag (claude, cursor); orchestrator-worktree creates the worktree via the Phase-2 verb and spawns the executor into it with the resolved argv/cwd (codex, opencode, kimi, kimi-code); none stays sequential. Undeclared/unknown/unresolvable isolation degrades to none — never an unisolated parallel run.

Fixes two shipped Phase-2 descriptors that per-host research found would fail at spawn: kimi lacked its headless flag (would launch the interactive TUI and hang the orchestrator), and kimi-code named a non-existent binary (Kimi Code installs as 'kimi'). Adds the worktree-path root confinement Phase 2 deferred here, and leading-dash guards on the resolver's prompt/cwd matching the existing git-argument guard.

Closes #2627

4a66d62d10 feat(#2584): Phase 2 — worktree create verb + orchestrator-exec resolver (#2625)
* feat(#2584): Phase 2 — worktree create verb + orchestrator-exec resolver

Phase 2 of the negotiated executor-isolation feature (ADR-1239 Codex-binding amendment). Two building blocks for `dispatch.isolation: orchestrator-worktree` hosts, both unconsumed — no scheduler wires them yet (that is Phase 3), so no runtime behavior changes.

worktree create verb (planWorktreeCreate / executeWorktreeCreatePlan / cmdWorktreeCreate in worktree-safety.cts, routed via routeWorktree in gsd-tools.cjs): validates the wave base, creates a bounded branch+worktree, records it in the run manifest reusing record-agent 4-field entry shape, returns the executor working directory. Bounded git (10s timeout, degrade-not-throw); all manifest read/parse/validate/dedupe precedes the single git side effect (no unmanifested-orphan on a bad manifest); timeout-only best-effort partial rollback (a clean collision-exit never removes a live peer worktree); fail-closed on bad base, unsafe leading-dash / .. inputs, and malformed/mis-shaped manifest.

resolveOrchestratorExec (host-integration.cts): pure descriptor->argv resolver reading the new runtime.orchestratorExec descriptor field (codex/opencode/kimi/kimi-code), fail-closed on missing/invalid shape. Validator (capability-validator.cjs) + a parity guard asserting every orchestrator-worktree host declares a resolvable orchestratorExec.

Adding the create route edits the installed gsd-core/bin/gsd-tools.cjs, so the golden-install-parity fixtures for all 19 runtimes are regenerated (npm run gen:golden) — the only changed hash is gsd-tools.cjs. CONTEXT.md glossary updated; capability-registry regenerated. Behavioral tests (worktree-safety + host-integration) incl. a fast-check property test and the parity sweep.

* chore: rebuild tracked state-transition.cjs to match #2400 source

The tracked compiled artifact drifted from src/state-transition.cts: #2400 (commit 2bcfaa2e2) added the progress.total_plans frontmatter sync to source but the tracked bin/lib/state-transition.cjs was never rebuilt, so the fix was not shipping to consumers of the compiled artifact. The mandatory build:lib step for Phase 2 surfaced the drift; recompiling makes the already-merged, already-changelogged #2400 fix effective. Artifact-only resync (no source/test change); drift class tracked by #2591.

* fix(#2474): gate worktree dispatch on project-level USE_WORKTREES too

The per-plan dispatch condition checked only USE_WORKTREES_FOR_PLAN

* fix: merge coverage gate into single-process check (#2474)

The test:coverage:unit script chained two c8 invocations with &&:
the first ran tests and wrote coverage data to .nyc_output/, the
second read that data for per-file branch checks. On fast CI runners
(ubuntu/24), the second process started before the filesystem flushed
the first process's writes — a classic TOCTOU race that caused
intermittent coverage gate failures.

Replace the two-process chain with a single c8 invocation that
generates both text and json-summary reports, followed by a Node
script (scripts/check-coverage-gate.cjs) that reads the JSON summary
once and checks both overall and per-file thresholds. No filesystem
race is possible because the JSON report is fully written before the
check script reads it.

* test(#1995): regression test for agent-<id> branch namespace

Add failing-first tests proving that normalizeCleanupManifestEntry and
planWorktreeRecordAgent reject Claude Code's current agent-<id> isolation
branches (only worktree-agent-<id> is accepted). Boundary tests cover both
namespaces plus rejection cases.

* fix(#1995): widen worktree branch regex to accept agent-<id> namespace

Claude Code's isolation="worktree" branch naming changed from
worktree-agent-<id> to agent-<id>. Widen the regex in all 7 locations
from ^worktree-agent-[A-Za-z0-9._/-]+$ to ^(worktree-)?agent-[A-Za-z0-9._/-]+$
so both namespaces are accepted. Introduce a shared WORKTREE_AGENT_BRANCH_RE
constant in src/worktree-safety.cts to prevent future drift.

Closes #1995

* fix(#1995): update workflow guards, test assertions, and baselines

Widen the branch-check regex in execute-phase.md and execute-plan.md.
Update all test assertions that checked for ^worktree-agent- to expect

7e905aa137 feat(#2505): Phase 0 — Kimi PreToolUse guard vocabulary normalization (precondition; carries PR #2326 forward) (#2518)
* fix(#2304): normalize Kimi tool vocabulary in PreToolUse guard payload checks

The Kimi [[hooks]] registrations translate the matcher to Kimi's tool
vocabulary (WriteFile|StrReplaceFile) but the guard scripts early-exit
unless the payload's tool_name is a Claude name (Write/Edit/MultiEdit),
so every guard was dormant on Kimi: the matcher fired, the script saw
WriteFile, and exit(0)'d.

Normalize the payload's tool_name at the top of each guard
(WriteFile -> Write, StrReplaceFile -> Edit; bare or module-qualified
kimi_cli.tools.file:* forms) before the check. Inlined per guard rather
than a hooks/lib/ helper because hook scripts are staged as standalone
files on every hook surface, and a sibling require is a staging
dependency that can fail silently.

Regression tests pipe Kimi-vocabulary payloads at each guard and assert
it engages (typed fields: exit status, decision, hookSpecificOutput) —
verified red against the pre-fix scripts, green after.

* fix(#2304): normalize Kimi tool_input fields and route block reasons to stderr

Cross-AI review of the initial fix, verified against kimi-cli source,
found the tool_name normalization alone leaves the guards dormant on a
real Kimi runtime: kimi-cli forwards tool_input verbatim
(src/kimi_cli/hooks/events.py), and its tool schemas
(src/kimi_cli/tools/file/{write,replace}.py) use path/content and
edit.old/edit.new (single Edit or list) — not Claude's
file_path/old_string/new_string. The guards read file_path, got '',
and exited 0 past the now-open tool_name gate.

Extend the per-guard normalization to the payload fields
(path -> file_path, edit -> old_string/new_string with list flattening),
and write the worktree guard's block reason to stderr as well as the
stdout JSON — Kimi feeds stderr, not stdout, back to the model on
exit 2 (docs/en/customization/hooks.md exit-code table).

Regression tests rewritten to Kimi's actual payload shapes (plus an
edit-list case and a stderr-reason assertion) — verified red against
the name-only fix, green after.

* fix(#2304): join all edit[] entries into old_string, matching new_string

Review nit on #2326: old_string took only edits[0].old while new_string
joined the whole list. Symmetric join removes the latent trap for any
future consumer sizing before/after content (e.g. the #2255 write guard).

* fix(#2304): normalize Kimi ReadFile vocabulary in read-injection scanner

Review Major 2 on #2326: gsd-read-injection-scanner.js had the identical
dormancy — its Kimi matcher fires on 'ReadFile' but the SCANNED_TOOLS
check only knew 'Read', so injected content in read files was never
flagged on Kimi installs.

Folds the same inlined normalization block into the scanner and extends
the shared KIMI_TOOL_NAMES map with ReadFile:'Read' in all four copies so
they stay byte-identical. Harmless in the three write guards: a
normalized 'Read' falls out of their Write/Edit allowlist exactly as the
unmapped name did. Field mapping verified against kimi-cli upstream
(src/kimi_cli/tools/file/read.py Params.path); the existing
path->file_path copy covers the scanner's file_path read.

* test(#2304): parity test binding the four inlined Kimi normalization copies

Review Major 1 on #2326: KIMI_TOOL_NAMES + normalizeKimiPayload is
deliberately inlined in four hook scripts (staging-dependency rationale,
unchanged), with the inverse table in bin/install.js — five
hand-maintained surfaces and nothing binding them.

Static binding, zero runtime coupling:
- the four inlined blocks must be byte-identical;
- each guard-map entry must be the value-inverse of
  convertKimiToolName() for its Claude name;
- every guard-relevant Claude tool (Write/Edit/MultiEdit/Read) must have
  a reverse entry — a vocabulary rename or extension that updates the
  installer without updating the guards now fails in CI instead of
  leaving a guard silently dormant (the #2304 recurrence door).

Negative-controlled: diverging one copy or dropping a map entry fails
the suite against the fixed code.

* test(#2304): regenerate golden parity fixtures for guard hook changes

CI red on #2326: all 10 golden-parity failures were the staged guard
hooks drifting from their fixtures. Regenerated with npm run gen:golden
(after npm run build) under throwaway HOME/CLAUDE_CONFIG_DIR; diff
verified to change exactly the four PR-touched guard entries per
surface, nothing else.

* test(#2304): regression tests for Kimi ReadFile engaging the scanner

Mirrors the per-guard Kimi vocabulary tests the PR added for the three
write guards: bare and module-qualified ReadFile produce the advisory,
path exclusions still apply post-normalization, unknown Kimi names stay
fail-open. Negative-controlled against the pre-fold scanner (the two
positive cases fail there; exclusion/fall-through correctly pass on
both sides).

* fix(#2304): normalize Kimi Shell vocabulary in workflow guard

Withdraws the disclosed out-of-scope split: verification showed the
Bash->Shell case needs NO different mapping — kimi-cli's Shell.Params
names its field `command` (src/kimi_cli/tools/shell/__init__.py), same
as Claude's Bash — and the guard's write branch (Write/Edit/MultiEdit
allowlist) was ALSO dormant on Kimi under its Shell|WriteFile|
StrReplaceFile matcher. Same defect class as the other four hooks.

Folds the identical inlined block into gsd-workflow-guard.js and
extends the shared map with Shell:'Bash' in all five copies (harmless
outside the workflow guard: a normalized Bash falls out of the other
guards' checks as before). Parity test now binds five copies and adds
Bash to the dormancy alarm. New workflow-guard test file exercises the
observable block (force-add on a worktree-agent branch): Shell bare and
module-qualified block with WORKTREE_AGENT_FORCE_ADD_FORBIDDEN, benign
Shell passes, Claude Bash unchanged — negative-controlled against the
pre-fold guard (the two Kimi cases fail there). Golden parity fixtures
regenerated; diff verified to change exactly the five guard entries per
surface.

* fix(#2304): map Kimi tool_output and route workflow-guard block to stderr

Third-party review (cross-AI verifier) caught two gaps in the revision:

1. Kimi PostToolUse events carry `tool_output`, not `tool_response`
   (kimi-cli src/kimi_cli/hooks/events.py post_tool_use()), so the
   read-injection scanner — which reads data.tool_response — was STILL
   dormant on real Kimi payloads; the earlier tests passed because they
   sent Claude-shaped payloads. The shared normalization block now maps
   tool_output -> tool_response (inert in PreToolUse guards, where the
   field is absent), and the scanner's Kimi tests send the real shape.

2. The workflow guard's force-add block wrote its reason to stdout only.
   Kimi's exit-2 protocol feeds stderr back to the model — the exact
   fix this PR already applied to the other blocking guard — so the
   newly-awakened block would have been a silent denial. Reason now
   also routed to stderr, asserted in the test.

Also: the scanner's "unknown name" test now uses a genuinely unmapped
name (FetchURL) — Shell stopped qualifying when it entered the map —
and the workflow guard's write branch (WriteFile advisory,
StrReplaceFile .planning pass) gains behavioral coverage. All five
copies stay byte-identical (parity test green); golden fixtures
regenerated, diff verified to the five guard entries per surface.
Negative-controlled: 3 new assertions fail against the pre-fix hooks.

* docs(#2304): update changeset to cover the full five-guard fix

Review round 2 (2026-07-18) flagged the changeset as stale: it was
written for the first commit and still described only the three guards
named in the issue. The shipped diff grew to five guards plus two
payload dimensions the original body never mentioned. The body now
names gsd-read-injection-scanner and gsd-workflow-guard, the ReadFile
and Shell vocabulary entries, the tool_output -> tool_response mapping,
and the workflow guard's stderr block-reason routing.

* test(#2304): regenerate kilo golden fixture after #2305 landed on next

The branch's fixture sweep predates 50efae13 (fix(#2305), PR #2327),
which made Kilo ship the five shared guard hooks. Rebased onto next and
re-ran the full generator sweep (gen:golden, size:baseline, and the
four registry/contract generators); the only delta across all of them
is kilo.json's five guard-hook hashes, matching this PR's hook edits.

* fix(#2304): fold Kimi normalization into the two shell hooks

The 2026-07-19 review found the last two guards with the #2304 dormancy:

- hooks/gsd-graphify-update.sh gated on tool_name == "Bash" but is
  registered on Kimi with matcher 'Shell' — Gate 1 never matched and the
  auto-rebuild was silently dormant. kimi-cli's Shell.Params names its
  field `command` (src/kimi_cli/tools/shell/__init__.py), same as Claude
  Bash, so only the name needs mapping: strip the module-path prefix,
  map Shell -> Bash.
- hooks/gsd-phase-boundary.sh read only tool_input.file_path, but Kimi's
  file tools name the field `path` (src/kimi_cli/tools/file/write.py +
  replace.py) — the hook read '' and .planning/ writes went undetected.
  Falls back to tool_input.path when file_path is absent, mirroring
  normalizeKimiPayload's precedence in the JS guards.

The normalization is reimplemented in shell — a byte-identity assertion
cannot span the JS<->shell boundary, so the parity test gains a
shell-guard vocabulary block that pins both scripts' mapping facts to
convertKimiToolName's live vocabulary instead of faking a byte binding.
Behavior is covered by negative-controlled tests beside each hook's
existing suite (verified red against the pre-fix scripts): Kimi Shell
dispatch (bare + module-qualified) with a WriteFile negative control in
graphify-auto-update.slow.test.cjs, and Kimi path detection, file_path
precedence, and a non-.planning negative control in hooks-opt-in.test.cjs.

Changeset updated to name all seven guards; golden install-parity
fixtures regenerated (diff is exactly the two hook entries per runtime;
size baselines unchanged).

* fix(#2304): use a Map for KIMI_TOOL_NAMES so prototype keys cannot pass the guard fall-through

A bare bracket lookup on an object literal resolves 'constructor',
'__proto__', 'toString', 'valueOf' and 'hasOwnProperty' through
Object.prototype to truthy functions/objects, so `if (!mapped)` failed
to short-circuit and data.tool_name was assigned a non-string. Map.get
returns undefined for those keys — the same shape the repo already uses
in canonicalizeRuntimeName (src/runtime-name-policy.cts). Applied
identically to all five inlined copies (review M1, PR #2326).

No new bypass class: unrecognized strings already fail open by design;
this fixes the lookup being wrong, not the posture.

* test(#2304): enumerate normalized guards by scanning hooks/, not a hardcoded list

The parity test's file list was a literal five-entry array — a sixth guard
with its own copy-pasted normalization block would be silently uncovered,
the exact divergence mode the test exists to prevent (review M2). Now the
list is a scan of hooks/*.js for the KIMI_TOOL_NAMES marker, with a floor
assertion so a scan that finds nothing fails instead of passing vacuously.
Also parses the Map declaration introduced by the M1 fix, and carries the
allow-test-rule annotation documenting the source-text scanning (review m4).

* test(#2304): parse hook JSON output instead of substring-matching raw stdout

workflow-guard.test.cjs asserted on unparsed stdout while read-guard.test.cjs
in the same PR parses the JSON envelope first — match the better pattern at
all four assertion sites (review m5).

* test(#2304): regenerate golden parity fixtures after Map conversion in the five guards

* docs(#2304): reset changeset pr:0 placeholder for Phase 0 PR (#2507)

The closed PR #2326's changeset carried pr:2326. Phase 0 of epic #2505
re-lands this fix on a fresh branch; the pr: field will be backfilled
to the real Phase 0 PR number immediately after gh pr create returns.

* docs(changeset): backfill PR #2518 for Phase 0 (#2507)

6d072435d0 test(#1975): consolidate 51 CLI + scripts-tooling regression tests into module suites
Fold 51 issue-named CLI black-box + scripts-tooling regression files into their
canonical module suites (runtime-launcher-parity, worktree-safety, install-*, managed-hooks,
read-guard, capability-registry, etc.), plus a NEW slash-command-namespace.test.cjs grouping
the 4 slash/colon-namespace-leak invariant suites that had no canonical owner. Verbatim
block-scoped describe wrappers; 427 subtests conserved 1:1.

Host-env pre-check (per B2): no CLI-receiving host sets a redirecting GSD_WORKSTREAM/GSD_PROJECT
value. One folded suite (bug-3668 runtime resolver) creates an extension-less PATH gsd-tools
stub + bash -c; co-locating it with the host's chmodSync tripped local/no-unguarded-nonportable-exec,
so it's now Windows-guarded (skip on win32) matching the host suite's own bash -c guard.

Regenerates regression-name allowlist (222->182), ratchets file-count allowlist (graphify 7->6,
docs entry removed), makes 26 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456;
prunes stale ids). Repoints 13 tests/ references across CONTEXT.md, COMMANDS.md/FEATURES.md
(EN + ja/ko/pt/zh) and ADR-0002. lint:ci green.

Final epic-#1969 batch. Fold 22 issue-named files: the 4 genuine repo-wide invariant
scans (551-eslint-bin-lib-coverage, bug-3054 stale /gsd-next, bug-3810 no-gsd-sdk-runtime-refs,
feat-3593 cli-negative-universal) into a NEW shared repo-invariants.test.cjs; the other 18 as
singletons into their nearest module suite (model-resolver, codex-config, runtime-converters,
security, state-transition, worktree-safety, roadmap-parser, etc.). Verbatim block-scoped
describe wrappers; 334 subtests conserved 1:1.

Host-env pre-check (B2+B6): the 6 CLI folds into GSD_TEST_MODE-setting hosts (model-resolver/
codex-config/runtime-converters) are benign — each origin independently sets GSD_TEST_MODE=1
itself (idempotent), unlike the B6 real-install case.

Regenerates regression-name allowlist (222->213), ratchets file-count allowlist (state 17->16),
makes 7 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456; prunes stale ids).
Repoints 2 tests/ refs in docs/TESTING-SUITES.md. lint:ci green.

The one subdir origin (tests/installer-migrations/001-legacy-orphan-files) moved up one
level into installer-migrations.test.cjs; its single ../../ module require corrected to
../ so it resolves from tests/ root (verified). Host-env pre-check: no CLI-receiving host
sets a redirecting GSD_WORKSTREAM/GSD_PROJECT value.

Regenerates regression-name allowlist (222->205), ratchets file-count allowlist (verify

Host-env pre-check (per B2): the only GSD_WORKSTREAM/GSD_PROJECT-touching destinations
(intel, planning-workspace) clear those vars hermetically, so folded CLI tests are safe.

cd56500d20 test: complete regex-escape class in worktree-safety assertion (#1589)
CodeQL alert #41 (js/incomplete-sanitization) flagged the partial
escape class /[-]/g at tests/worktree-safety.test.cjs:645 — it only
escaped hyphen-minus, leaving 13 other regex metacharacters (notably
backslash) unescaped. The canonical class /[.*+?^${}()|[\]\\]/g is
what every sibling escape in the test suite already uses
(bug-2839, bug-2760, 4-phase-complete, phase6-capstone-conformance).

Today dormant: the flag array is a hardcoded [a-z-] literal, so the
expanded class is a no-op for the four existing flags and the regexes
they produce are byte-identical. The fix prevents future drift — a
contributor adding e.g. '--output=file' would have silently introduced
a regex wildcard.

All 69 tests in the file pass. No user-facing behavior change.

* refactor(#1294): T-final — delete the core.cjs re-export spine (epic #1267 complete)

After T0–T6 nothing imports core, so retire the spine and its scaffolding:
- delete src/core.cts (and the gitignored gsd-core/bin/lib/core.cjs artifact;
  remove its .gitignore + eslint-ignore entries)
- delete scripts/lint-core-spine-imports.cjs + its allowlist; drop it from the
  package.json lint:ci chain
- regenerate docs/INVENTORY-MANIFEST.json (drops the core.cjs surface)
- sweep stale references: CONTEXT.md glossary back-compat clauses (spine retired,
  callers import the leaf directly), planning-config.md CONFIG_DEFAULTS owner,
  and false present-tense core.cjs claims in leaf-module docstrings

The ADR-857 decomposition is complete: the former Core god-module is fully
dissolved into its leaf modules; no re-export spine remains. No behaviour change.

bin/install.js used require(path.join(_gsdLibDir, 'core.cjs')) (a computed

~8 test files referenced core.cjs via path.join/readFileSync/existsSync/FILE_ARG
forms the literal-string migration grep missed. Route install.js's symbols to
their leaves (RUNTIME_PROFILE_MAP->model-catalog, resolveTierEntry/EFFORT_SET->
model-resolver) and repoint/adjust the test references to the leaves. Recovers

48d9cec6fe refactor(#1268): re-home core re-export-spine squatters + migration-convergence lint (#1272)
Re-home the 6 implementation functions squatting in the core.cjs re-export
spine (ADR-857) into the modules whose interface they belong to, with core
re-exporting them BY REFERENCE so all 32 callers + the shim-identity tests
keep resolving unchanged:
- worktree-safety: resolveWorktreeRoot, pruneOrphanedWorktrees
- git-base-branch (broadened to the Git Query Module): gitWorktreeInfoInternal
- agent-install-check (new leaf): getAgentsDir, checkAgentsInstalled
- delete the _resetRuntimeWarningCacheForTests wrapper; consumers use a
  shared resetRuntimeWarningCaches() helper in tests/helpers.cjs

Add scripts/lint-core-spine-imports.cjs (migration-convergence lint with a
30-importer allowlist, wired into lint:ci) so the staged spine retirement
provably converges: CI fails on any new ./core import. Register the new
generated agent-install-check.cjs in eslint-ignore + .gitignore +
INVENTORY-MANIFEST.json.

No behaviour change. First tranche (T0) of epic #1267.

dfbb684843 fix(#706): skip rescue of already-committed SUMMARY to avoid worktree cleanup merge_failed (#709)
* fix(#706): skip rescueSummaryArtifacts when SUMMARY is already committed

rescueSummaryArtifacts now probes `git cat-file -e HEAD:<path>` before
copying a SUMMARY.md into the main checkout.  When the file is already
committed on the worktree branch, copying it as an untracked file causes
`git merge --no-ff` to abort with "untracked working tree files would be
overwritten by merge" — a permanent merge_failed cleanup-wave failure.

Fail-closed on timeout: if cat-file is unreliable we skip rescue (the
merge will surface the collision as it did before, which is recoverable).

Adds 4 new test cases in worktree-safety.test.cjs covering:
- committed SUMMARY skipped, merge succeeds (#706 regression case)
- committed SUMMARY skipped even when timeout (fail-closed)
- uncommitted SUMMARY still rescued (existing contract preserved)
- rescue failure on ENOSPC still propagates (unchanged)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(#706): treat cat-file exit 128 as uncertain — skip rescue (fail-closed)

The previous guard skipped rescue only when `exitCode === 0` (committed) or
`timedOut`. Any other non-zero exit, including `128` (fatal git error: corrupt
object store, unborn HEAD, missing repo), fell through and PROCEEDED with
rescue — potentially re-creating the #706 untracked-file merge collision.

Fix: rescue ONLY when `exitCode === 1` (cat-file definitively reports the
object absent). All other outcomes — 0 (committed), 128 (fatal), null/SIGTERM
(timeout), or any other code — are treated as "uncertain → skip rescue".

Also corrects the JSDoc bullet that still referenced `git ls-files
--error-unmatch` (the old mechanism); updated to `git cat-file -e HEAD:<relPath>`.

Regression test added: asserts rescue is SKIPPED when cat-file returns exit 128,
leaving the merge to surface the issue safely rather than silently copying an
already-committed file.

463cffd894 chore(#604): rename get-shit-done/ runtime directory to gsd-core/ (#615)
* chore(#604): rename get-shit-done/ runtime directory to gsd-core/

Renames the installed runtime directory `get-shit-done/` to `gsd-core/` so the
on-disk name matches the package (`@opengsd/gsd-core`), repo, and binary
(`gsd-tools`). The npm package name and binary are unchanged; npx/npm consumers
are unaffected.

Mechanical (bulk, ~90% of the diff):
- `git mv get-shit-done gsd-core`
- Swept path/identifier references across the repo via
  `perl -pe 's/get-shit-done(?!-\w)/gsd-core/g'`. The negative lookahead
  preserves the five legitimate slug variants that are NOT the directory:
  get-shit-done-{OLD,cc,classic,cli,redux} (old package/repo names).
- Build/manifest wiring: package.json (bin, files, coverage globs),
  tsconfig.build.json (outDir), ~86 .gitignore build-output entries,
  stryker.config.mjs, scan-ignore files, install.js path strings.
- Frozen (not rewritten): CHANGELOG.md history; translated docs
  (README.<locale>.md and docs/{ja-JP,ko-KR,pt-BR,zh-CN}/).

New logic (review here):
- src/installer-migrations/003-rename-get-shit-done-to-gsd-core.cts: a proper
  ADR-0008 installer migration. On upgrade it walks the legacy
  `~/.claude/get-shit-done/` tree, classifies each file via the prior install
  manifest, and emits remove-managed / backup-and-remove for managed files
  while PRESERVING unknown user-added files. Symlink-safe (skips a symlinked
  root and symlinked entries; bounds-checks every path under configDir). The
  framework rolls back on install failure. Emptied dirs may remain (framework
  has no recursive dir-removal primitive) — documented.
- scripts/lint-legacy-dir-name.cjs: CI regression guard forbidding the bare
  `get-shit-done` directory token (split token to avoid self-match; case-
  insensitive; `(?!-\w)` lookahead allows the slug variants; allowlists
  CHANGELOG, translated docs, and `gsd-allow-legacy-name` marker lines).
  Wired into the lint-tests CI job.
- Restored scripts/lint-package-identity-drift.cjs detection regexes (the
  mechanical sweep had wrongly rewritten the old-name patterns it exists to
  detect) and marked them as intentional legacy references.
- TDD tests for the migration and the guard; do.md slash-command guard regex
  tightened so a `/gsd-core/bin` path segment is not mistaken for a command;
  changeset + docs/installer-migrations.md row added.

Breaking: the installed runtime path moves `~/.claude/get-shit-done/` ->
`~/.claude/gsd-core/`. Migration 003 removes the stale legacy dir's managed
files (preserving user files) on upgrade. Users with custom hooks/configs
hardcoding the old path must update them.

- Do not sweep pending .changeset/*.md (ephemeral release-note fragments,
  like CHANGELOG); reverted those body edits so 5 pre-existing malformed
  fragments (missing type/pr) no longer enter the PR diff and trip docs-lint.
  Allowlisted .changeset/ in the legacy-name guard accordingly.
- Allowlisted TEST-EXAMPLES.md and docs/explanation/security-model.md in
  prompt-injection-scan.sh: they contain intentional injection examples /
  security-model prose; the path-reference rewrites are kept.

CodeQL alerts on this PR are pre-existing (alert lines unchanged by this PR;
none in the new migration/guard) and are out of scope for the rename.

* fix(#604): resolve CodeQL alerts surfaced on this PR

The rename diff touched files carrying pre-existing CodeQL findings; per the
no-pre-existing-dismissal rule, fixing every surfaced alert rather than waving
them off. All behavior-preserving:

- scripts/ci-test-scope.cjs: build the config-path match from string
  .includes() instead of a RegExp over an arg-derived value (js/regex-injection).
- src/profile-output.cts: escape backslashes before pipe-escaping desc/safeName
  so the table-cell escape is complete (js/incomplete-sanitization).
- tests/{bug-2643,bug-2808,docs-parity-live-registry}: two-pass HTML-comment
  strip so a bare/unclosed `<!--` cannot survive (js/incomplete-multi-character-sanitization).
- tests/inline-plan-threshold: drop the no-op `\s`->`\s` identity replace,
  keep the meaningful POSIX-class conversion (js/identity-replacement).

Verified: build:lib green; the touched test files + ci-test-scope + profile-output
suites pass; lint:legacy-name clean.

* fix(#604): correctly resolve remaining CodeQL alerts (regex-injection + sanitization)

The prior commit's fixes for two alerts were ineffective:
- ci-test-scope.cjs js/regex-injection: the alert is the CLI-arg-derived `file`
  reaching static regex `.test(file)` calls (not the config rule). Removed ALL
  regex over file/t — startsWith/includes/=== string checks + an isWindowsHint
  helper — so there is no regex sink for the tainted value.
- js/incomplete-multi-character-sanitization (3 test files): a single
  `.replace(/<!--...-->/g,'')` can let `<!--` re-form. Replaced with a fixpoint
  loop (replace until stable) plus a final bare-opener strip.

Verified: no regex over file/t remains; ci-test-scope + the 3 test suites pass;
lint:legacy-name clean.

* fix(#604): make ci-test-scope + comment-strippers regex-free to clear CodeQL

CodeQL flags the regex PATTERNS syntactically (regex-injection on the
--files arg split; incomplete-multi-character-sanitization on the <!--...-->
replace), so loop fixes do not satisfy it. Made these paths regex-free:
- ci-test-scope.cjs splitFiles: char-by-char separator tokenizer (no /[,\\s]+/).
- 3 test files: indexOf/slice HTML-comment stripper (no .replace(/<!--/)).
Behavior preserved; ci-test-scope + the 3 suites pass; guard clean.

* fix(#604): unblock security base64 scan on the large rename diff

The security job hit its 10m timeout: base64-scan.sh choked on the binary
test fixture tests/feat-3594-parser-property-style.test.cjs (embedded NUL/
non-UTF8 bytes -> thousands of bogus blobs + "ignored null byte" warnings),
and the ~800-file rename diff is slow to scan regardless.

- scripts/base64-scan.sh: skip binary-by-content files (grep -Iq .) — they
  can't carry base64-obfuscated *text* and feeding NUL bytes through the
  per-line scanner is pathologically slow. collect_files already filtered
  binary *extensions*; this catches binary *content* in text extensions.
- .github/workflows/security-scan.yml: raise the security job timeout 10m->30m
  to accommodate very large diffs (the scan itself is unchanged).

Verified locally: scan skips the fixture, 0 "ignored null byte" warnings,
0 findings, exit 0.

* fix(#604): sweep get-shit-done refs introduced by merging next

The branch was updated with next (#614/#384/#618 etc.), which reference the
get-shit-done/ dir (still named that on next). Swept the stale references in
the merged files to gsd-core so the rename stays consistent and lint:legacy-name
passes:
- commands/gsd/discuss-phase.md (runtime-launcher shim paths)
- src/core.cts (getAgentsDir layout comments)
- tests/bug-384-agents-runtime-aware.test.cjs (require path to runtime lib)

Verified: guard 0 violations; build green.

* fix(#604): exclude gsd-core/ path segments from bug-3683 command cross-ref invariant

The #614 runtime-launcher shim added to discuss-phase.md references
`${_GSD_RUNTIME_ROOT}/gsd-core/bin/...`. bug-3683's REF_PATTERN excluded path-y
refs only via lookbehind, but `}` precedes `/gsd-core/` in the shim, so it
mis-read the directory path as a dangling `/gsd-core` command ref (same class as
the #604 bug-2954 fix). Added a trailing `(?![\w-]*\/)` so `/gsd-<x>/...` path
segments are not treated as slash-command references.

Verified locally on BOTH platforms before pushing:
- mac (node 26) full suite: 0 failures
- gsd-test-runner (linux, node22 image) full suite: 0 failures
- bug-3683 + bug-2954 pass.

* fix(#604): lazily resolve findProjectRoot in gsd-tools (harden flaky CI)

CI intermittently failed state.test's gsd-tools subprocess with
"findProjectRoot is not a function" (flip-flopping across legs; not reproducible
on mac full suite, gsd-test linux full suite, test:unit, or state.test x8).
findProjectRoot is a re-export from core.cjs (sourced from project-root.cjs);
binding it via destructure at module-load can be undefined under a load-ordering
edge. Resolve it lazily at call time via a small wrapper so the lookup happens
after core.cjs is fully initialized.

Verified green on BOTH platforms before pushing:
- mac (node 26) full suite: 0 failures
- gsd-test-runner (linux, node22) full suite: 0 failures
- state.test.cjs: 106/106; gsd-tools loads cleanly.

* fix(#604): allowlist verification-patterns.md placeholder examples in secret scan

The rename git-mv'd references/verification-patterns.md into gsd-core/, pulling
it into the secret-scan diff. It documents stub/placeholder RED-FLAG env-var
examples (illustrative Stripe test-key / database-URL / API-key placeholders) —
not real credentials. Added it to .secretscanignore with the strict annotation,
mirroring the existing gsd-core/workflows/plan-phase.md exception.

Verified locally: secret-scan-lint --strict OK; secret-scan --diff origin/next
exits 0 with 0 findings.

2726af1246 fix(#245): surface worktree.cleanup-wave SUMMARY rescue copy failure (#616)
* fix(#245): surface worktree.cleanup-wave SUMMARY rescue copy failure

rescueSummaryArtifacts recorded each path in the rescued set before the
copyFileSync attempt; a thrown (and swallowed) copy left the path marked
rescued, so the dirty-block filter excluded it and the worktree was
merged + removed despite the SUMMARY never being written — silent data
loss. Now a path is recorded only after a successful copy (or verified
identical dest), and a write failure is surfaced as a blocked entry with
reason 'summary_rescue_failed', failing closed instead of removing the
worktree.

cda3d7a5ab fix(3804): worktree.cleanup-wave rescues uncommitted SUMMARY.md (#81)
* fix(3804): rescue uncommitted SUMMARY.md in executeWorktreeWaveCleanupPlan

Ports the shell-fallback SUMMARY rescue logic from quick.md into
executeWorktreeWaveCleanupPlan. Before the dirty-state check, all
*SUMMARY.md files under <worktree>/.planning/ are copied to the main
tree (if absent or divergent), then filtered out of the git-status
porcelain output. A worktree whose only dirty file is the executor's
uncommitted SUMMARY.md now proceeds to merge+remove instead of
returning cleanup_blocked/worktree_dirty.

Adds two TDD tests (#3804):
- Rescue-only dirty state (SUMMARY.md alone) → cleanup succeeds
- SUMMARY + non-SUMMARY dirty files → cleanup still blocks

* fix(3804): normalize relPath to forward slashes for Windows porcelain match

On Windows, `path.join` produces backslash separators while `git status
--porcelain` always emits forward slashes. The rescued-paths Set would
never match porcelain output, causing the dirty-check filter to ignore
SUMMARY rescue and block cleanup on Windows.

Also normalize the test assertion for `rescued[0].dest` to use
forward slashes so the test passes on both platforms.

918f987a19 feat(#2982): extend no-source-grep lint to catch var-binding readFileSync.includes() (#2985)
* feat(#2982): extend no-source-grep lint to catch var-binding readFileSync.includes()

The base lint (scripts/lint-no-source-grep.cjs) only catches
readFileSync(...).<text-method>() chained directly. The much more
common var-binding form escapes it:

  const src = fs.readFileSync(p, 'utf8');
  // 50 lines later
  if (src.includes('foo')) {}        // ← still grep, lint missed it

Scan of the test suite found ~141 files using this pattern.

Implementation built TDD per #2982 with structured-IR assertions:

  scripts/lint-no-source-grep-extras.cjs
    - detectVarBindingViolations(src) — pure detector, two passes:
      pass 1 collects vars bound from readFileSync, pass 2 finds any
      <var>.<includes|startsWith|endsWith|match|search>( on those vars.
    - detectWrappedAssertOkMatch(src) — flags
      assert.ok(<expr>.match(...)) which escapes the assert.match rule.
    - VIOLATION enum exposes stable codes for tests to assert on.

  scripts/lint-no-source-grep.cjs
    - Wires the new detectors into the existing per-file check; one
      additional violation row per file with the first 3 sample tokens.

  tests/bug-2982-lint-var-binding.test.cjs
    - 13 tests, all assertions on typed VIOLATION enum / structured
      records. Covers all 5 text-match methods, multi-var, no-bind,
      string literal (must NOT trigger), wrapped assert.ok(.match),
      and assert.match (must NOT double-flag).

Migration backlog (#2974 expanded scope):

  - 42 files annotated `// allow-test-rule: source-text-is-the-product`
    (legitimate — they read .md/.json/.yml files whose deployed text
    IS the product)
  - 3 files annotated `// allow-test-rule: pending-migration-to-typed-ir [#2974]`
    (read .cjs/.js source — clear migration debt)
  - 95 files annotated `pending-migration-to-typed-ir [#2974]` with
    `Per-file review may reclassify as source-text-is-the-product
    during migration` (mixed — manual review under #2974)

After this lands the lint reports 0 violations on main; new
violations in PRs surface immediately.

Closes #2982
Refs #2974

* test(#2982): fix truncated test name per CR

The label ended with a bare '(' from a copy-paste mishap. Now reads
'does NOT flag .matchAll(...) — matchAll is not match, so
assert.ok(.matchAll(...)) is not flagged'.
