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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Both paths are covered by red-checked regression tests.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Refs #4544

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

No behaviour change beyond the error-message text.

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

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

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

Documentation only; no code change.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

f09e7ed08c fix(#4137): existsSync-guard the Homebrew Cellar rewrite in normalizeNodePath (#4375)
* test(#4137): keg-only Homebrew Cellar path falls back to raw execPath

Regression tests for the Homebrew branch of normalizeNodePath: the rewrite
to <prefix>/bin/node must be existsSync-guarded like the mise/volta
branches, falling through to the raw execPath when the keg-only formula
was never linked into <prefix>/bin. Also makes the existing #3181/#2185
Cellar assertions hermetic by injecting existsSync stubs (granting
existence to exactly the one candidate each asserts) so they no longer
depend on the runner machine's real /usr/local/bin/node.

* fix(#4137): existsSync-guard the Homebrew Cellar rewrite in normalizeNodePath

The Homebrew branch of normalizeNodePath returned <prefix>/bin/node
unconditionally — the only one of five runtime branches that never probed
its rewrite candidate. On a keg-only or versioned Homebrew install
(node@24 never brew-linked) that path does not exist, so every managed
hook command baked by resolveNodeRunner/buildBakedNodeToken/
buildNodeRunnerChainToken failed at invocation with exit 127, /bin/sh:
<prefix>/bin/node: No such file or directory.

Guard the rewrite with the already-injected existsSync exactly like the
mise and volta branches: when <prefix>/bin/node exists (linked formula)
the rewrite is byte-identical to today; when it does not, fall through to
the raw execPath — a working keg path instead of an immediately broken
one. Also drops two now-unused constants from the regression tests.

* test(#4137): make the #977 non-fnm Cellar assertions hermetic too

The Bug #977 folded block's two 'still maps to stable symlink' assertions
called normalizeNodePath without an existsSync stub, silently depending
on the runner machine's real /usr/local/bin/node (present on the Linux
bench image, absent for /opt/homebrew). With the #4137 guard these become
environment-dependent; grant each exactly the one candidate it asserts.

77e2472ca0 enhance(#4221): replace installer Read() deny rules with a managed secret-read guard hook (#4236)
* feat(#4221): gsd-secret-read-guard PreToolUse hook + registration

Add hooks/gsd-secret-read-guard.js, a blocking PreToolUse guard on
Read|Grep|Bash that denies reads of .env, .env.<suffix> and .secrets
(the .env.example/.sample/.template/.dist templates stay readable).
Read checks file_path; Grep checks an explicit path and judges the glob
per brace alternative; Bash runs a two-pass token scan (quotes, comments,
redirects with fd digits, separators, $( )/backtick/<( ) recursion,
heredoc bodies never scanned as commands, nested bash -c/eval rescans,
git <ref>:<path> shapes) with a closed non-reading exemption set for
existence checks. Fail-open crash policy; 1 MiB commands are denied as
command-too-large; more than 64 glob alternatives as glob-too-complex.

Why: Claude Code 2.1.259 makes every `cd DIR && grep …` compound prompt
for approval whenever any Read() deny rule exists, even in auto mode. A
hook denial is not a permission rule and never arms that check. The
installer-written deny rules are retired in the follow-up commit.

Registration: hooks.json (Read|Grep|Bash, timeout 5), build-hooks
HOOKS_TO_COPY, managed-hooks-registry, runtime-hooks-surface (blocking
guard with BLOCKING_GUARD_TIMEOUT_S; Kimi ReadFile|Grep|Shell),
shell-command-projection managed sets, installer-migration-report,
OpenCode/Kilo plugin (grep tool mapping, include -> glob, dispatch),
docs tables in five locales, ADR-766 always-on list, regen:derived
fixtures, and a new table-driven unit suite.

* test(#4221): pin the secret-read guard in existing hook gates

Register gsd-secret-read-guard.js in every existing hook gate: the
hooks-crash-policy table (deny row; 6 -> 7 deny cases), plugin-manifest
REQUIRED_HOOKS and its Read|Grep|Bash group, docs-hooks-table-parity
EXPECTED_SURFACE_HOOKS, install.test MANAGED_JS_HOOKS, install-minimal-
hooks JS_HOOKS/BLOCKING_GUARDS, portable-node-runner GUARD_HOOKS,
kilo-upgrades PLUGIN_GUARD_HOOKS, the Kimi normalization-parity and
typed-payload floors, the OpenCode adapter (grep mapping, include ->
glob, three dispatch tests) and a Kimi TOML matcher assertion.

* fix(#4221): retire installer Read() deny rules (legacy filter)

Rename GSD_CLAUDE_DENY_PERMISSIONS to GSD_CLAUDE_LEGACY_DENY_PERMISSIONS
and stop adding the three Read(.env) / Read(.env.*) / Read(.secrets)
strings. mergeClaudePermissions now only filters them out of an existing
permissions.deny: an absent deny key stays absent, a malformed one is
still repaired to [], and an array emptied by the filter is deleted so
no `"deny": []` residue is left. Uninstall filters the same legacy list
and, symmetric with the Antigravity branch, drops an emptied allow or
deny key and an emptied permissions object.

Unlike the #2278 allow-side migration there is no surviving current
deny list, so the constant is renamed rather than mirrored. Removal is
byte-exact: a hand-written identical rule is indistinguishable from the
installer's and is removed too (the manifest never recorded permission
strings). USER-GUIDE and CONTEXT.md updated.

* test(#4221): flip install-regressions deny-rule assertions to the retired shape

The fresh-merge, non-destructive merge, idempotency, end-to-end install,
reinstall and uninstall assertions now expect no Read(.env*) deny rules
and no permissions.deny key on a fresh install; the deny:null repair case
is kept. A new describe block covers the legacy filter: retired strings
removed with a user entry kept, partial sets, near-miss strings
untouched, idempotency, GSD-only deny array deleted, a pre-existing
empty deny preserved, and uninstall symmetry for allow/deny/permissions.

* chore(#4221): add changeset fragment for PR #4236

* fix(#4221): case-fold names; scan shell stdin and xargs pipes

Review round 1 (trek-e):

- Blocker: secret-name matching is now case-insensitive in the Read,
  Grep (path and glob) and Bash paths, so `.ENV` / `.Secrets` on a
  case-insensitive filesystem are recognized as the same secret file.
- Major: a shell interpreter's script is now scanned wherever it comes
  from. The tokenizer keeps heredoc bodies as per-segment tokens and
  records separator operators; pass 2 groups by segment id and resolves
  bash/sh/zsh/dash/ksh/su invocation mode: `-c` (including combined
  `-lc`) scans the script operand, a file operand is checked as a file
  (a `<( )` operand's echo/printf output is reconstructed), otherwise
  stdin is the script and heredocs, here-strings and a piped echo/printf
  source are scanned. `eval` joins all its operands; `source`/`.` handle
  process substitution. Data heredocs (`cat <<EOF`, the commit-message
  shape) stay unscanned.
- Major: `… | xargs <cmd>` checks the upstream segment's operands as
  file names when the sub-command reads (`echo .env | xargs cat`,
  `find . -name .env | xargs cat`); `-a`/`--arg-file` suppresses the
  inference; a shell sub-command's `-c` script is scanned.

Header, USER-GUIDE bullet and changeset updated; documented gaps now
include piped scripts from non-echo sources and `exec`/`timeout`
wrappers. 60 new suite cases pin the block and allow shapes.

c6efe2905c fix(#4087): stage the hook helpers the Codex bundle's hooks require (#4117)
* fix(#4087): stage the hook helpers the Codex bundle's hooks require

CODEX_HOOKS_TO_COPY is a flat, hand-maintained filename allowlist that never
recursed, and Codex is excluded from installSharedHooksBundle() — the path that
stages hooks/lib/ for full-bundle runtimes — by an !isCodex gate. Excluding
hooks/lib/ was a correct scoped decision for #3579 until #3911 (2ea5efc15) gave
gsd-context-monitor.js a real require('./lib/hook-exit.js'). From then on every
fresh --codex install staged the hook without its helper and the hook died with
MODULE_NOT_FOUND at module load, before its own try/catch, on every event Codex
registers it for. The install still exited 0, so nothing surfaced it.

Reproduced before changing anything, in a sandboxed CODEX_HOME: four hooks
staged, no lib/, and the installed hook exiting 1 on "Cannot find module
'./lib/hook-exit.js'".

Rather than hand-add today's three helpers — which re-breaks the next time a
Codex-bundled hook grows a lib dependency, exactly how this regressed — the
transitive-require walk already written for Cursor in 704859e9c is extracted out
of writeCursorHooksJson into an exported stageTransitiveHookLibs(), Cursor is
rewired onto it, and the Codex copy loop calls it. bin/install.js already
required that module, so this adds no new seam. Cursor's staged set is
byte-identical to base, compared file by file.

Extraction surfaced a latent defect in that walker, fixed here: its regex read
`./X` and `./lib/X` identically, but from a hook SCRIPT a bare `./X` is a
sibling in hooks/ — gsd-check-update-worker.js requires
`./managed-hooks-registry.cjs`, which is not a lib — so it demanded
hooks/lib/managed-hooks-registry.cjs and the fail-loud guard threw. Seeds now
match only `./lib/X`; lib files still match both, which is the
sibling-within-lib case 704859e9c exists for. Cursor never exposed it because
none of its scripts carries a bare sibling require.

Three further grammar gaps closed after review, each in the fail-closed
direction: an extensionless `require('./lib/x')` is valid CommonJS and was
resolved literally, failing the install on a legitimate require — now resolved
through .js/.cjs and written under its resolved name; a NESTED `./lib/sub/x.js`
could not be expressed by the character class and was a SILENT miss, the one
failure mode this function exists to remove — now refused loudly; and a capture
carrying no alphanumeric character is prose, not a module name — hooks/lib/
injection-patterns.js documents this very mechanism with the literal string
require('./lib/...'), which captured `...` and sent the resolver hunting for
hooks/lib/... . The scan is still not comment-aware, which is disclosed at the
call site rather than papered over.

Seeded from the entries THIS invocation staged rather than probing the
destination, so a file left by an earlier install whose source is no longer
allowlisted cannot contribute helpers for a hook that is no longer shipped.

The #3579 boundary holds: three of ten helpers ship, gsd-graphify-rebuild.sh
among those correctly absent. Seven rows — three driving a real install into a
sandboxed config dir (with HOME sandboxed for the child, since Codex's skills
kind resolves from os.homedir() and the #3712 guard rightly refuses otherwise)
and four pinning the discovery grammar directly. All proven fail-first; the
set-equality row also reds on over-staging, which the count-based version it
replaced did not catch.

Fixes #4087
Fixes #4098

* fix(#4087): stage the hooks/lib helpers the Windsurf guards require

Review of #4117, verified as asked and reproduced against a real install.

Windsurf sets hostBehaviors.skipSharedHooksInstall, so like Cursor it never
reaches installSharedHooksBundle -- the only other stager of hooks/lib --
and writeWindsurfHooksJson staged its two Cascade guards without the
helpers both require at module load: gsd-windsurf-pre-write.js requires
./lib/hook-exit.js and ./lib/git-probe.js, gsd-windsurf-pre-command.js
requires ./lib/hook-exit.js. stageTransitiveHookLibs had one call site,
Cursor's.

Measured on a fresh `--windsurf --global` install into a sandboxed HOME:
the installer exited 0, hooks/ held only the two scripts and package.json,
and executing either installed guard exited 1 with "Cannot find module
'./lib/hook-exit.js'" -- so every pre_write_code and pre_run_command event
failed at load while the install reported success. The same command with
`--cursor` staged four helpers and its hook ran, which is the control.

Pre-existing rather than introduced here: at merge-base 05092ff36 the same
three require lines exist and writeWindsurfHooksJson already staged no
lib/, and this PR's diff carried no reference to Windsurf. Fixed here
anyway because the helper this PR extracted is the right tool and a second
runtime is a few lines onto it.

writeWindsurfHooksJson now calls stageTransitiveHookLibs after staging its
scripts, with the same gsd: -> gsd- transform the scripts receive, so a
helper is rewritten the same way as its caller. The install-tree fixture
regenerates with exactly hook-exit.js, git-probe.js, cli-exit.js and
exit-code-registry.js added and no other fixture moved. Two rows execute
the INSTALLED guards, beside the Codex rows they mirror; the existing
windsurf-hooks-bridge rows run the guards from source and test behaviour,
a different question, and are left as they are. Both new rows fail-first
against the unfixed compiled artifact -- gsd-core/bin/lib, which is what
bin/install.js loads -- on the MODULE_NOT_FOUND assertion.

Emitted-Drift-Ack-Hash: hooks/lib/git-probe.js — first staged for Windsurf, whose pre-write guard requires it; the file itself is unchanged

* test(#3981): blocking-guard timeout budget and 5→120 migration

Fresh registration must carry a host-stall-proof 120 s budget on the
six blocking PreToolUse guards; existing managed timeout:5 entries
are migrated; non-managed entries and advisory budgets are untouched.

* fix(#3981): give blocking guards a host-stall-proof timeout budget

Claude Code treats a timed-out hook as non-blocking, so the 5 s
budget on the six blocking PreToolUse guards silently dropped the
gates exactly when the host stalled under load. Registers them at
120 s (covers every observed stall, max 84.3 s) and migrates existing
managed timeout:5 entries in place, context-monitor-backfill shape.
Advisory hook budgets are unchanged.

* enhance(#3624): local/no-exact-case-env-access — ratchet ADR-1703 onto production env reads (epic #3411 Phase 4)

Extends ADR-1703's portability rule catalog with a second production-runtime
rule: it flags an exact-case read of a Windows case-varying environment
variable (PATH, PATHEXT, ComSpec, USERPROFILE, TEMP, TMP, APPDATA) off any
receiver that is not process.env itself, matched via an env-shaped-receiver
check to avoid colliding with ordinary `.path`-named properties elsewhere in
the tree.

Exports the seam's private `_envGet` as `envGet` so the rule's remediation
message names a real helper, and fixes the one pre-existing violation the
tightened rule found (`src/runtime-hooks-surface.cts`'s `env.APPDATA` read).

Closes #3624

* fix(#3624): extractStaticName recognizes non-computed Literal destructuring keys; add missing accessor-call test case

Review findings from the code-review + isolated-adversarial passes:
- extractStaticName only matched non-computed Identifier keys, so a
  destructuring like `const { 'PATH': v } = opts.env;` (the issue's own I8
  acceptance case) silently evaded the rule. Widened to accept a Literal key
  regardless of computed, which is safe for MemberExpression too (its
  non-computed property is always an Identifier by grammar).
- Added the missing RuleTester valid case for "a case-insensitive accessor
  call" (envGet(env, 'PATH')) from the issue's Done-when checklist.

e9868a92ba fix(#1875): route installer settings/defaults writes through atomic, lock-guarded primitives (#3966)
* fix(#1875): route writeSettings through atomicWriteFileSync

writeSettings is the sole writer of settings.json/settings.local.json for
six runtimes and wrote them with a naked fs.writeFileSync. Hosts discard the
entire settings file on any parse failure, so a crash mid-write cost the user
every hook, permission, env var, and statusline they had — not just GSD's.

Route it through the atomicWriteFileSync (temp+rename) already used elsewhere
in the installer and already bound in this file.

withWriteFailure in the migration integration harness matched only the final
destination path, so an atomic write bypassed the injection entirely and turned
a rollback assertion into a vacuous pass. It now also matches the .tmp- sibling.

* fix(#1876): honor the readSettings null contract in the #338 local-merge leg

readSettings returns null only for an unparseable file — its documented
"preserve existing, don't touch" signal. The #338 migration coerced that null
to {} and wrote the result back, so a settings.local.json with one stray comma
lost all its non-GSD content on the next install.

The guard stands the whole migration down rather than just the local write:
skipping the merge while still stripping the shared file would destroy the GSD
entries outright instead of relocating them.

Aborting here reaches a pre-existing latent crash that the clobber had been
masking. Both are fixed, with their own regression test:

- the unparseable-settings guard returned bare `undefined` while all five
  sibling early exits return the full result shape, so installAllRuntimes'
  statusline lookup (results.find(r => r.runtime)) threw;
- handleStatusline dereferences result.settings, which is null on every early
  exit, so the call site now falls through to the banner branch.

Both crashes reproduce on unmodified next with a malformed settings.local.json
and no migration involved.

* fix(#1877): lock and atomically write the machine-global ~/.gsd/defaults.json

Every non-Claude install read-modify-writes ~/.gsd/defaults.json with no lock
and two separate naked whole-file writes. The file is read by every runtime and
project on the machine, so concurrent installs lost each other's key, and a
crash in either write window truncated it — silently, because the read path
swallows parse errors and treats a corrupt file as absent.

Take the existing acquireInstallMigrationLock around the read-modify-write and
apply both mutations in one atomicWriteFileSync. An install that changes nothing
no longer rewrites the file at all.

Existing semantics are unchanged: the explicit resolve_model_ids:true opt-in
(#1569) and an existing "omit" are preserved, non-canonical values still default
to "omit" (#1156), a pre-existing runtime string is preserved (#2395), the
malformed-non-object recovery (#1657) stands, and both console lines still print
when both keys change.

The #2834 structural test sliced a fixed 1200-character window from the function
source; the added lock comment pushed an asserted token past it. The window now
tracks the function body, so a comment or guard cannot red it spuriously.

2ea5efc151 enhance(#3911): hooks declare their crash policy (#3960)
* enhance(#3911): give hooks an exit seam that needs no build

ADR-3889 Phase 7 foundation. The 19 shipped enforcement hooks hold 91 of the
epic's 128 terminators and cannot reach `terminateNow` today.

The obvious route — requiring `gsd-core/bin/lib/cli-exit.cjs`, as
gsd-agent-isolation-guard.js already does for two other modules — is rejected.
That precedent carries its own warning (#3582): those files are tsc output,
gitignored and absent on a raw plugin-marketplace or git-clone install, so the
hook must first call ensureRuntimeBuild() to self-heal. Making the module a
hook needs IN ORDER TO TERMINATE depend on a build inverts the dependency, and
its failure mode is precisely the fail-open this phase exists to remove: a
guard that cannot terminate cannot deny. `lint-hooks-runtime-build-seam`
already encodes that concern, and Design B would have had to add an
ensureRuntimeBuild() call to all 19 hooks to satisfy it.

So `hooks/lib/` becomes a third emit location for cli-exit and a fifth for the
registry, preserving the invariant `src/cli-exit.cts`'s own header states: it
imports nothing but node:fs and its sibling registry, and the generator
dual-emits that sibling alongside each copy so a relative require resolves next
to whichever copy loaded it. Shipping needed no change — build-hooks.js already
declares HOOKS_SUBDIRS_TO_COPY = ['lib'].

Proven, not asserted: the two files are copied into an otherwise-empty tmpdir
and a child process requires them and terminates — PASS exits 0, HOOK_DENY
exits 2 with the payload on both stdout and stderr. That test fails the moment
the hooks copy gains a require reaching outside hooks/lib/.

Also fixed inline: the registry's fifth target let any `--write` test overwrite
the real committed hooks/lib/exit-code-registry.js, because the test helper
derived only three of the other output paths. It now redirects all five, and a
regression test asserts every committed artifact is byte-identical after a
redirected write.

Install-tree goldens pick up the two new shipped paths across 11 runtimes —
insertions only, no removals. lint:ci was green while they were stale, so this
was found by regenerating rather than by a gate.

Verification runs on the remote runner.

Refs #3911

* enhance(#3911): declare a crash policy, and migrate the write guard

Adds `hooks/lib/hook-exit.js` — the hook-facing vocabulary over `terminateNow`,
hand-written because the cli-exit copy beside it is generated:

  allow(payload)          exit 0
  deny(payload, stderr?)  exit 2
  crash(onCrash, payload) whichever the hook DECLARED

`crash()` takes the policy as a required argument with no default, which is the
whole mechanism: fail-open by accident stops being expressible. A hook must
name ALLOW or DENY at the call site, and an unrecognized value terminates
INTERNAL rather than guessing. Fail-open stays legal; fail-open by omission
does not.

`gsd-write-guard.js` is the first hook migrated, all 12 sites, and it exposed a
gap in the seam. `terminateNow`'s doc comment justified its fd-2 write by
citing this hook's `emitBlock` — but modeled it as sending the same bytes to
both streams, when `emitBlock` actually sends full JSON to stdout and only the
bare `reason` string to stderr, because Kimi's hook bus feeds stderr verbatim
back to the model. Migrating as written would have turned a readable sentence
into a JSON blob for Kimi-backed agents.

#3911 requires both "all 19 hooks terminate through terminateNow" and "no
hook's effective default changes". Those are jointly satisfiable only by
teaching the seam to carry a distinct stderr payload, so `terminateNow` gains
an optional third argument: omitted, behavior is byte-for-byte what it was; a
string is written raw, which is exactly the Kimi case. The doc comment's
inaccurate claim about emitBlock is corrected in place.

Proven rather than asserted: the pre-migration file is reconstructed from HEAD
and driven with the same catastrophic-shrink payload as the migrated one —
exit code, stdout and stderr all byte-identical.

Verification runs on the remote runner.

Refs #3911

* enhance(#3911): all 19 hooks terminate through the seam

Migrates the remaining 18 enforcement hooks onto allow/deny/crash. An AST walk
now reports zero `process.exit(` call sites across every `hooks/*.js` — down
from the 91 the census measured.

Each hook with an outer catch declares its policy once, at module top, with the
reason that policy is right for that specific guard: a read guard that cannot
scan must not block the read; a statusline that renders every prompt must
degrade rather than crash; an injection scanner must not retroactively block a
result already returned. Those sentences are the deliverable — they are what
turns fail-open-by-accident into fail-open-on-purpose. No hook's effective
default changed.

Wiring exposed two defects, both fixed here rather than noted.

A SECOND stdout/stderr-splitting site turned up in `gsd-workflow-guard.js`'s
`emitForceAddBlock`, matching the pattern already known from the write guard —
full JSON to stdout, bare reason to stderr for the Kimi bus. It uses the
`stderrPayload` argument added in the previous commit, which is now carrying
its second real caller rather than one special case.

More seriously, `terminateNow` emitted both streams inside ONE try, so a
payload that failed to serialize aborted before the stderr write ever ran. The
two windsurf guards write nothing to stdout on a block and only a reason string
to stderr, so `deny(undefined, reason)` exited 2 with EMPTY stderr — a deny
that silently loses its reason, which is the exact "fails with success" class
this epic exists to close. The streams are now emitted independently, each with
its own guard, and `undefined` means "nothing to write for this stream" rather
than an error. Regression tests inject a throwing write on one fd and assert
the other still receives its payload; they fail against the single-try version.

Byte-identity was proven per hook, not assumed: each pre-change file is
reconstructed from HEAD and driven side by side with the migrated one across
its normal path, its deny path, malformed stdin and empty stdin — exit code,
stdout and stderr compared.

Verification runs on the remote runner.

Refs #3911

* enhance(#3911): harden the three shell hooks, and pin every hook's policy

`gsd-phase-boundary.sh`, `gsd-session-state.sh` and `gsd-validate-commit.sh`
gain `set -euo pipefail`.

The expected hazard did not materialize, and that is worth recording: every
intentionally-non-zero command in all three is already the condition of an
`if`/`elif`, which `set -e` never fires on, and none of them reads a
possibly-unset variable or pipes through a grep that may legitimately match
nothing. No `|| true` guards were needed. Each hook was still checked
command-by-command before the flags went in rather than after.

Twenty-one before/after cases across the three hooks — disabled and enabled,
planning and non-planning, missing STATE.md, malformed JSON, the Kimi payload
shape, quoted and unquoted `-m`, valid and over-long Conventional Commits —
all match on exit code, stdout and stderr.

The hardening is shown to actually fire, not merely added: with a stubbed
`node` that fails at the JSON-emit step, phase-boundary and session-state go
from silently exiting 0 with empty stdout to failing visibly with the error
surfaced. No such case could be constructed for `gsd-validate-commit.sh`,
whose every statement already sits inside an if-condition — recorded as
unproven rather than claimed.

`tests/hooks-crash-policy.test.cjs` adds the per-hook coverage the issue asks
for, table-driven over all 19 hooks rather than 76 hand-written cases: normal
allow, deny where a deny path exists, crash-honors-the-declared-policy, and an
unclosed-stdin case — the one `process.exitCode` structurally cannot serve. The
deny assertions encode each hook's ACTUAL stream split rather than a uniform
shape, since four of the six deliberately differ. A drift guard enumerates
`hooks/*.js` and fails if a terminating hook is ever added without a row.

Writing those tests surfaced two hooks that emit a block decision in their JSON
body and exit 0. Both were checked rather than assumed, and neither is a
fails-with-success: `gsd-read-injection-scanner.js` is PostToolUse, where the
tool has already run and exit 2 has no meaning, and `gsd-cursor-subagent-start.js`
follows Cursor's JSON-body protocol. They are deliberately left alone — a
mechanical sweep to `deny()` would have broken exactly these two.

Verification runs on the remote runner.

Refs #3911

* fix(#3838): the commit validator says when it could not validate

#3911 claims to subsume #3838. Measurement said otherwise, so this closes it
for real rather than by assertion.

`set -euo pipefail`, added earlier on this branch, does NOT fix #3838: bash
exempts a command used as an `if` condition from `set -e`, and all three of the
hook's swallow-and-pass sites are exactly that shape. Verified against the
hardened hook with a node shim that fails only the classifier call — a
non-conforming commit still exited 0 with empty stdout AND empty stderr,
indistinguishable from "your commit conforms". That is the defect verbatim.

All three sites named in #3838 now capture the real exit status instead of
consuming it as a condition, and each distinguishes its genuine negative from
"could not run":

- the classifier: 0 = is a git commit, 1 = genuinely not one, anything else =
  could not classify. Its `node -e` now wraps the require and the call in
  try/catch and exits 3 on a throw, so a broken require chain can never be
  mistaken for `isGitSubcommand` legitimately returning false — which is the
  arm that matters, since `token-scanner.cjs` is a gitignored build artifact
  and a fresh checkout lands there.
- the opt-in config read and the JSON command extraction get the same
  treatment.

On "could not run" the hook emits a diagnostic to stderr naming which check
failed and why, then exits 0. The issue confirms this is safe — it is a
PreToolUse hook, so stderr does not disturb the JSON protocol — and ranks it
the smallest sufficient fix. The gate still fails open, but it can no longer do
so silently, which is the whole complaint: a validator that disables itself
quietly costs more than one that is absent, because it is trusted.

Both controls are unchanged and pinned by tests: a conforming commit still
passes silently, a non-conforming one still exits 2 with its existing block
payload. The defect test asserts stderr is non-empty and names the failure; it
fails against the pre-fix hook.

Verification runs on the remote runner.

* docs(#3911): document the hook crash-policy contract

Reference and Explanation via a new docs/features fragment (FEATURES.md is

ARCHITECTURE note on the hooks section.

How-To: docs/how-to/declare-a-hook-crash-policy.md, indexed from docs/README.md
— a hook author now has to choose and declare a crash policy, which is more
than one step and crosses into which harness protocol their hook speaks. It
covers allow/deny/crash, writing an ON_CRASH reason that is actually useful,
when a deny needs a distinct stderr payload, the two hooks whose harness reads
a JSON-body decision and must NOT use deny(), and what to do when a check
cannot run at all — with #3838 as the worked example.

Refs #3911

* test(#3911): prove the seam actually ships, and stop hand-rolling temp cleanup

Two review findings.

The acceptance criterion 'hooks/dist/** stays in parity via the build seam
(lint:hooks-runtime-build-seam)' was misstated and unmet: that lint checks
something else — that a hook requiring a compiled gsd-core/bin/lib module also
calls ensureRuntimeBuild(). Nothing exercised that the three new hooks/lib
files reach hooks/dist/lib at all. That gap is not theoretical: #770 is a
recorded ship-blocking bug where a new hook never shipped because a copy list
missed it. The suite now builds dist through the repo's own ensureBuiltHooks(),
byte-compares each shipped copy against its source, and spawns a child that
requires the SHIPPED dist copy and denies — which is what catches a copy that
exists but cannot resolve its sibling registry.

gsd-validate-commit.sh hand-duplicated mktemp/run/rm three times; one idempotent
trap on EXIT replaces them, guarded so cleanup cannot alter the exit status.
Behavior-neutral across five cases, with temp-file counts taken before and
after each run.

Refs #3911

* fix(#3911): stage transitive hook lib requires, not just one level

The remote run returned 7 failures across 3 real causes.

The important one is a PRODUCTION bug this phase exposed rather than caused.
`writeCursorHooksJson` scanned each hook script for `./lib/X` requires exactly
one level deep and never re-scanned the lib files it staged for their own
sibling requires. Nothing had a transitive lib dependency before, so the gap
was invisible. Adding hook-exit.js -> cli-exit.js -> exit-code-registry.js
made real Cursor installs ship a bundle that dies at require time with
MODULE_NOT_FOUND. It now walks to a fixed point, and a real installed Cursor
hook runs to completion.

The staging harness in shared-hooks-dir-resolution hand-copied its fixture, so
the injection scanner crashed at require time and its exit-1 was being read as
a policy decision. Migrated to copyScriptWithDeps, which walks the require
graph — the repo's recorded rule for this class, since adding another
copyFileSync keeps it alive for the next person.

The missing-lib-source test in cursor-hook-workspace-roots hardcoded which lib
file it expected to be named in the abort message; the same throw now fires for
a different file first. Its assertion is unchanged in substance — staging still
must abort rather than ship a broken hook — only the name is no longer pinned.

The last one was my own test asserting an uppercase reason code. Measured
against origin/next: the pre-change hook emits the same lowercase
'config_unreadable', so the test was wrong, not the migration. Corrected to the
real value rather than making the code match the test.

Verification runs on the remote runner.

* chore(#3911): regenerate the cursor install-tree golden

* fix(#3911): a git probe that timed out is not a negative

A macOS CI lane failed three deny cases at 2084ms, 2112ms and 2177ms — just
past the 2000ms budget these hooks give their git probes. The three that passed
took 72ms, 595ms and 651ms. Under shard contention `git rev-parse` overruns,
the hook reads the non-zero result as "not a git repo", and allows with exit 0
and empty stdout AND empty stderr. Under load, the guards silently stop
guarding. That is ADR-3889's thesis exactly, sitting inside the security hooks
this phase is about.

The repo had already recognized the class in one place — gsd-cursor-subagent-start.js
fail-closed-denies on `git_timed_out` (#3045) — but nowhere else.

`hooks/lib/git-probe.js` classifies a probe's outcome, distinguishing a real
non-zero exit from ETIMEDOUT, a signal kill, and a spawn failure, rather than
folding all four into `status !== 0`. Three guards route their eight git probes
through it.

The resolution is the same shape #3838 took, and the same one that issue
endorsed as smallest-sufficient: fail open, but loudly. **No exit code changes
on any path** — a developer on a loaded machine is still not blocked, which
keeps #3911's declaration-pass contract intact for exit codes. What changes is
that the hook now says on stderr which probe could not answer, instead of
presenting silence as a clean verdict.

Scope was checked across every hooks/*.js, not just the three that failed:
gsd-agent-isolation-guard spawns no git; gsd-statusline's two probes gate only
a cosmetic display segment, not an allow/deny decision, and are left alone.

The C2 deny assertion was a real-race test — it demanded exit 2 while a slow
git legitimately yields 0. It now requires the hook to either deny, or allow
with a diagnostic naming the probe that could not run; a silent allow still
fails, so the assertion is not vacuous. A deterministic regression stubs git on
PATH to sleep past the budget rather than waiting for load to reproduce it.

Verification runs on the remote runner.

Refs #3911

* test(#3911): a PATH shim cannot intercept the hooks' git spawn on Windows

The deterministic timeout regression stubbed git on PATH and asserted the
guard reports rather than silently allows. It passes on Linux and macOS and
failed on Windows in 83ms and 176ms — the stub was never invoked at all.

Mechanism: the hooks call spawnSync('git', args) with no shell:true, so on
Windows CreateProcess resolves git.exe only and never a PATH .cmd shim. The
git.cmd branch could not have worked and is removed rather than left implying
a Windows path that does. Adding shell:true to the hooks to serve a test would
change product behavior and widen an injection surface, so the case is skipped
on win32 only, with the mechanism written into the skip reason so a future
reader does not 'fix' it that way.

Linux and macOS keep the coverage, and macOS is where the underlying fail-open
was actually caught.

682eaae3f0 enh(#2876): retire the dead and pass-through exports from bin/install.js (#3615)
* enh(#2876): retire the dead and pass-through exports from bin/install.js

The installer exported 197 names and had zero production consumers - every
non-test require of it repo-wide sits inside a comment. Its interface was
shaped by test access, not by callers.

Removes 9 dead exports and 61 pass-throughs, repointing their tests onto the
extracted modules' own interfaces. 197 down to 127.

Every count in the issue was wrong: 197 exports not 188, 9 dead not 12, 61
pass-throughs not 49, 44 test files not 42 - and the audit itself then missed
7 more consumer files. restoreUserArtifacts was on the dead list but ceased to
exist in phase 6, and two _GSD_EFFORT_MANIFEST_* names listed as dead are now
genuinely asserted, so acting on that list would have deleted live exports.

7 of the 9 dead names collide with an independent declaration that install.js
delegates TO. Each removal was justified by which declaration a reference
resolves to, never by whether the name appears somewhere.

Coverage parity was the gate rather than test greenness: per-file counts were
captured before any edit and diffed after. 44 of 45 files are byte-identical;
the single delta is one added assertion, not a loss.

The sweep for scattered require sites found two forms static grep misses -
require(VARIABLE) and multi-line require() - plus tests asserting that
install.js re-exports the SAME object, which now assert retirement instead.

* fix(#2876): close review findings — restore the duplicate-body guard, sweep orphaned code

Both review engines found real defects in the first cut.

The DEFECT.GENERATIVE-FIX single-owner guard from #1511 had been repointed
from a reference-identity check to install.X === undefined. Those are not
equivalent: the guard exists to catch a duplicate function body reintroduced
into install.js, and the replacement passes cleanly if that duplicate is used
internally and never exported. It now walks bin/install.js's real top-level
bindings, so it catches a duplicate under either shape, exported or not -
strictly stronger than the check it replaced. Proved by injecting a duplicate
and watching it go red.

That weakening survived the coverage-parity gate because the assertion count
never moved. The gate compares counts, so an assertion that changes meaning
rather than number is invisible to it.

Removing the exports had orphaned their wrapper bodies: 14 dead wrappers, 9
consts and 9 destructure entries, several pre-existing and found by the same
sweep. Dead code left in the file this phase exists to shrink.

Three more comments claimed re-exports this phase removed, and tests were
reading Cursor and Windsurf hook constants from install.js's local copy while
calling functions from the hooks surface - equal today, with nothing holding
them equal. The local consts now reference the owning module.

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.

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.

* 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.

* chore(#3045): backfill changeset pr number

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

* 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.

c61dd49d95 enhance(#2255): blocking catastrophic-shrink guard for curated .planning/ writes (#2301)
* feat(#2255): blocking catastrophic-shrink guard for .planning writes

Adds hooks/gsd-write-guard.js, a PreToolUse hook that hard-blocks
(decision: 'block', exit 2) a whole-file Write collapsing a curated
.planning/ artifact (ROADMAP.md, .planning/milestones/*-ROADMAP.md,
STATE.md) below 40% of its on-disk line count. Files under 40 lines
are exempt; GSD_ALLOW_PLANNING_SHRINK=1 (named in the block message)
bypasses for legitimate milestone resets.

Fix 3 of #973 — the only defense independent of per-agent tool config.
Registered on the Claude plugin surface (hooks.json), settings-json
runtimes (runtime-hooks-surface.cts, self-contained pattern), Kimi
spec, and the OpenCode/Kilo plugin buses. Golden install fixtures and
INVENTORY regenerated; regression tests negative-controlled (16/16
RED with the hook absent, 16/16 GREEN with it present).

* chore(#2255): backfill changeset pr number to 2301

* enhance(#2255): address review — fail-closed reads, typed block output, registration, property test

Review fixes for trek-e's CHANGES_REQUESTED on PR #2301:

- Blocker 2: register gsd-write-guard.js in BUNDLED_GSD_HOOK_FILES
  (no-shipping-drift test).
- Blocker 3: update the always-on hook enumerations in ADR-766 and
  CONTEXT.md from six to seven.
- Major 4: fail CLOSED on non-ENOENT read errors — only a missing file
  (new-file Write) passes; EACCES/EISDIR/ELOOP/etc now block, with a
  typed readError field and the override still honored. Tested, with a
  negative control against the pre-fix hook.
- Major 5: fast-check property test for the SHRINK_RATIO/FLOOR_LINES
  budget contract (blocked ⟺ newLines < oldLines*SHRINK_RATIO above the
  floor; sub-floor always exempt), boundary examples pinned.
- Major 6: block output now carries typed oldLines/newLines/
  overrideEnvVar fields; tests assert on those instead of regexing the
  free-form reason string.
- Minor: CURATED_PATTERNS are case-insensitive (case-insensitive-FS
  bypass on macOS/Windows); limit+1 boundary tests added for both the
  floor and the ratio.

* enhance(#2255): engage the write guard on Kimi's native payload shape

The guard shipped with Claude-vocabulary checks (tool_name 'Write',
tool_input.file_path), which #2304 showed leaves a guard dormant on
Kimi: the [[hooks]] matcher is registered pre-translated but kimi-cli
forwards its native payload verbatim — tool_name 'WriteFile' (bare or
module-qualified) and tool_input.path per its tool schemas
(src/kimi_cli/tools/file/write.py). The guard matched, saw an unknown
name, and exited 0.

Apply the same per-guard normalization PR #2326 gives the three
sibling guards (name + field mapping, inlined — hook scripts stage as
standalone files), and write the block reason to stderr as well as
stdout JSON: Kimi feeds stderr, not stdout, back to the model on
exit 2, so a stdout-only reason blocks without telling the model why
or naming the documented override.

Regression tests pipe Kimi-shaped payloads (engage, qualified-name,
stderr-reason) plus exemption pins (StrReplaceFile stays out of scope
by design; non-curated paths pass) — verified red against the pre-fix
guard, green after.

* enhance(#2255): rebase onto next; regenerate golden-parity fixtures

* enhance(#2255): wire the escape hatch into complete-milestone's reorganize step

Review Blocker 1: the guard hard-blocked /gsd:complete-milestone's ROADMAP
reorganize — the tree's only legitimate milestone reset and the exact caller
GSD_ALLOW_PLANNING_SHRINK was built for. The reorganize step now performs the
rewrite through a shell write with the hatch set on the command (a hook
inherits the runtime env, so a bare Write cannot carry a per-step override),
and a binding test derives the env var name from the guard's typed output and
asserts (a) the workflow step sets it and (b) the guard passes the identical
catastrophic payload under it — so the next complete-milestone.md edit cannot
silently re-break the wiring.

* enhance(#2255): drop dead Edit-class mapping from normalizeKimiPayload

Review Major 1: StrReplaceFile -> 'Edit' and the old_string/new_string
reconstruction were unreachable-by-effect — the guard exits 0 for any
tool_name !== 'Write', so nothing ever read the fields they set, leaving
guaranteed-surviving mutants against the Stryker bar. The map now carries
only WriteFile -> 'Write'; the StrReplaceFile exemption test message states
the fall-through it actually exercises.

* enhance(#2255): review minors — American spellings; writeSync before exit(2)

Minor 1: normalised/normalise -> American house style. Minor 2: the two
block paths wrote stdout+stderr via async pipe writes then exit(2) —
async-on-Windows, unflushed at exit; fs.writeSync(1/2, ...) makes the block
payload durable.

* enhance(#2255): assert stderr equals the typed reason, not raw prose

Minor 3: the last raw-text match in the suite pinned override-name prose on
stderr. The contract is "stderr carries the reason Kimi feeds back" — now
asserted as stderr non-empty and byte-equal to the parsed stdout.reason.

* enhance(#2255): bind the write-guard's Kimi normalization into the parity test

Review Major 2: the guard's normalizeKimiPayload is a 4th inlined copy with
nothing binding it. This extends PR #2326's kimi-guard-normalization-parity
test (same path and helpers, authored as a superset so either merge order
resolves cleanly): sibling byte-parity is existence-gated zero-or-all —
trivially green until #2326 lands, full-strength after — and the write-guard
copy is bound semantically (map is the value-inverse of convertKimiToolName;
the Kimi name for Write must map, or the guard is dormant on Kimi; the
path -> file_path half must be present). Byte-parity is deliberately not
asserted for this copy: it legitimately omits the Edit-class mapping
(Major 1 — dead code in a Write-only guard).

* enhance(#2255): refresh golden-parity fixtures for revised guard + workflow

* chore(#2255): regenerate golden fixtures after rebase onto next

The committed fixture hashes were generated against a tree predating
next's latest 11 commits, which independently modified the same
install-parity surface. Rebased onto next and regenerated with
`npm run gen:golden`.

Verified: against upstream/next the regenerated fixtures differ by
exactly this PR's own entries -- hooks/gsd-write-guard.js (new),
hooks/managed-hooks-registry.cjs, plugins/gsd-core.js, and
gsd-core/workflows/complete-milestone.md. No unrelated drift.

* fix(#2255): regenerate workflow size baseline for complete-milestone

`complete-milestone.md` grew 31071 -> 32061 (+990) when the round-2
review fix bound GSD_ALLOW_PLANNING_SHRINK=1 into the reorganize step,
but tests/workflow-size-baseline.json was never regenerated. The
per-file workflow baseline test (issue #1074) failed on
ubuntu-latest/22 and both macOS shard 1/3 jobs.

The growth is justified: it is the escape-hatch binding requested in
review round 2 (the guard must not hard-block the tree's only
legitimate milestone reset), not incidental bloat.

Regenerated via `npm run size:baseline`; the diff is exactly the one
entry.

* chore(#2255): regenerate golden fixtures and size baseline after rebase onto next

* enhance(#2255): bind the shrink escape hatch mechanically — single-use sentinel the guard consumes

Round-5 M1: the per-step `GSD_ALLOW_PLANNING_SHRINK=1 tee` prefix was inert
(no PreToolUse hook exists on Bash in this family; the write succeeded by
dodging the guard, not by the override firing) and the protection was prose.
The hatch is now a transport code consults: complete-milestone's reorganize
step arms `.planning/.gsd-allow-shrink` with the target's path, keeps the
Write tool as the sanctioned path, and the guard — at the block point only —
verifies the sentinel is fresh (15 min) and names the pending target, then
CONSUMES it and allows that one write. Path-bound + single-use + freshness
keep it from becoming a standing unlock. The env var remains as the
interactive transport, where it can actually reach the hook.

Regression tests written first (negative control: 3 failed pre-fix): the
armed-sentinel Write passes and consumes; stale does not exempt; a token for
a different file neither exempts nor is consumed; the binding test now takes
the sentinel name from the guard's typed output (overrideSentinel), asserts
the step arms it, and asserts the step no longer routes the rewrite around
Write via a shell pipe.

Also in this commit, same file:
- m2: block emission is exception-safe — emitBlock() wraps both writeSync
  sites in their own try/catch that still exits 2, so an EPIPE can no longer
  convert fail-closed into the outer catch's fail-open.
- Header discloses the two reviewed design limits (cumulative sequential
  shrink; lexical match vs symlinked paths) per round-5 scoping.

* docs(#2255): document the sentinel transport across guard surfaces; changeset ends with the (#2255) parenthetical (m4)

USER-GUIDE bullet, INVENTORY row (en + ja/ko/pt/zh), the
runtime-hooks-surface registration comment, and the changeset now describe
both hatches — the single-use sentinel for workflow steps and the env var
for interactive use — instead of implying a per-step env can reach a hook.
The changeset's trailing `Resolves #2255.` prose becomes the `(#2255)`
parenthetical the repo's fragments use (round-5 m4).

* chore(#2255): regenerate derived families on the rebased tree (full sweep)

Full generator sweep after rebasing onto next @ the body-parser-patched
lockfile: build, gen-inventory-manifest, gen:golden, size:baseline. Every
regen delta verified to be either a PR-owned entry (gsd-write-guard.js,
complete-milestone.md, INVENTORY/USER-GUIDE) or exact convergence to next's
committed value for entries our arbitrary-side conflict resolution had left
stale (all 18 runtime fixtures checked mechanically).

* test(#2255): use helpers.cleanup for sentinel teardown, not raw fs.rmSync

The repo's local/no-raw-rmsync-in-tests rule exists for the Windows-EBUSY
retry budget; the sentinel disarm now rides it like every other teardown.

* chore(#2255): regenerate derived families after rebase onto next

Full sweep on the rebased tree (build -> gen-inventory-manifest ->
gen:golden -> size:baseline). Every delta is either a PR-owned entry
(hooks/gsd-write-guard.js, its registration surfaces
hooks/managed-hooks-registry.cjs and the two plugin buses,
gsd-core/workflows/complete-milestone.md) or exact convergence to
next's committed value across all 18 runtime fixtures.

* chore(#2255): regenerate derived families after rebase onto next @ a5180d96

Rebase onto current `next` (a5180d96) resolved 12 conflicting
golden-install-parity fixtures; all regenerated via the full generator
sweep (build, gen:golden, size:baseline) rather than a single generator.

`lint:generated-sync` reports every generated artifact in sync. All 45
differing fixture keys and the single workflow-size-baseline entry map
to files this PR actually touches; no foreign drift.

* fix(#2255): remove the stale unguarded reorganize_roadmap step (round-8 blocker)

complete-milestone.md carried a second ROADMAP-collapsing step,
`reorganize_roadmap`, distinct from the sentinel-armed
`reorganize_roadmap_and_delete_originals` this PR wired. It is a vestige
of the pre-archive-then-reorganize design: it sits BEFORE
archive_milestone, so executing it as written would collapse ROADMAP.md
before the archive snapshots the full phase detail — and its Write is
exactly the shape gsd-write-guard hard-blocks, with no hatch armed. The
file's own success criteria describe only one reorganize outcome
(Backlog-preserving, overwrite-in-place — the later step's properties),
and archive_milestone points forward to "the reorganize step".

Removed rather than wired, per the round-8 review's confirm-and-remove
option. A new binding test asserts the sentinel-armed step is the ONLY
reorganize step in the workflow, so an unguarded collapse step cannot be
silently reintroduced (negative-controlled: fails against the pre-fix
tree). Golden-parity fixtures and the size baseline regenerate for the
shrunk file; every changed fixture key is complete-milestone.md's own.

* test(#2255): document why the read-error injection is a path collision, not an fs monkeypatch

Round-8 nit: the non-ENOENT tests inject via a directory-at-target-path
collision instead of the repo's fs-method monkeypatch pattern. That is
deliberate, not drift — runHook exercises the hook as a spawnSync child
process, so an in-process fs.readFileSync patch (the pattern the cited
siblings use on require'd, in-process code) can never reach the code
under test. Record the reasoning at the injection site.

* chore(#2255): regenerate derived families after rebase onto next @ 0d08c320

Rebase onto current next (0d08c320) for the CONFLICTING/DIRTY state. All 32
conflicts were generated artifacts (19 golden-install-parity, 12 install-tree,
workflow-size-baseline); resolved arbitrarily and regenerated via a full
generator sweep (build, gen:golden, size:baseline, gen-inventory-manifest)
rather than hand-merged. No source conflicts.

Regen diff verified against the PR's changed-file set: 7 distinct differing
keys, all PR-owned (gsd-write-guard.js, managed-hooks-registry.cjs,
plugins/gsd-core.js, complete-milestone.md, and their .kimi mirrors).
lint:generated-sync clean.

* chore(#2255): regenerate derived families after rebase onto next @ 9138271b

Conflict set was 20 paths, every one a generated artifact, zero source
conflicts — resolved arbitrarily during the replay and regenerated here,
per the maintainer's round-9 recipe (never hand-merged).

Generator sweep (not just gen:golden): npm run build, gen:golden,
size:baseline, gen-inventory-manifest, gen:registry. INVENTORY-MANIFEST
came back byte-identical, so the merged value was already correct.

Regen diff verified == PR-touched entries: every differing leaf key
attributes to a file this PR changes (complete-milestone.md, the guard,
managed-hooks-registry.cjs, both plugin buses) — derived from the
changed-file set, not a feature-name filter.

* fix(#2255): port the #2595 Kimi-payload hardening the base landed for the sibling guards

Self-found via the round-10 base sweep: a8b40fa5 (#2547/PR #2595) hardened
gsd-prompt/read/worktree-path-guard's normalizeKimiPayload after this PR was
authored, and this guard carried all three pre-fix shapes:

- `path` now wins outright over a model-supplied `file_path` — kimi-cli's
  WriteFile schema carries no `file_path`, so a payload pairing a curated
  `path` with a spurious `file_path: ""` had the guard reading '' and
  exiting 0 while kimi-cli wrote to `path` (one-key bypass, no crash needed).
- null/primitive payloads pass through deliberately instead of throwing into
  the fail-open catch.
- the `file_path` read is typed (`typeof === 'string'`), closing the
  crash-to-allow on `[]`/`{}` — this is what the base-added
  kimi-guard-typed-payload-reads scan flags.

Negative-controlled: the shadowing payload exits 0 against the pre-fix guard
and 2 against this one.

* fix(#2255): round 9 Major 2 — stop printing the sentinel recipe in the agent-facing denial

The block message ended by telling the blocked agent exactly how to arm the
single-use sentinel — handing the #973 actor a mechanical self-authorization
in the moment it is blocked. The recipe is gone from the prose; the
corrective advice and the env override's name stay (the latter is a #2255
acceptance criterion, and a per-step env prefix cannot reach a hook anyway),
and the typed overrideSentinel field stays for the binding tests. The hatch
remains documented in USER-GUIDE.md and complete-milestone.md, where humans
and the workflow engine read.

* fix(#2255): round 9 Minors 1-2 — realpath-resolve the target before the curated match; disclose the /i Linux cost

Minor 1: a Write to a non-curated path that symlinks into a curated file was
not matched while writeFileSync followed the link — the target is now
realpath-resolved before the curated match (ENOENT keeps the lexical
resolution so new-file Writes still pass; any other realpath error falls
through to the read, which fails closed). Negative-controlled: the symlink
payload exits 0 against the pre-fix guard, 2 against this one. Test skips on
win32, where symlink creation needs privilege.

Minor 2: the header's design-limits block now names the unconditional /i
cost on case-sensitive Linux (a genuinely distinct .planning/roadmap.md is
also treated as curated) next to the stateless limit, and drops the closed
symlink limit.

* test(#2255): round 9 Minors 3-4 — CRLF counting pin + a passing Write leaves a fresh sentinel unburned

Minor 3: countLines' split('\n') is CRLF-safe for a count (the \r rides
along), confirmed by trace in the review — this pins it against this repo's
recurring CRLF regressions, on both sides of the compare and at the 40%
boundary.

Minor 4: consumeSentinelFor runs only after the ratio check would block, so
a within-tolerance Write never burns the workflow's token — true by
construction, previously un-asserted.

* fix(#2255): round 9 Major 3 — correct the stale env-var line in archive_milestone's summary

complete-milestone.md's "After archival" bullet still said the reorganize
happens "under GSD_ALLOW_PLANNING_SHRINK=1" — the wording from the round-2
design this PR's own history rejected in round 5 (a per-step env var cannot
reach a hook; setting it in a Bash step silently does nothing). It now points
at the sentinel mechanics the reorganize step actually documents, matching
that step and USER-GUIDE.md.

* docs(#2255): round 9 Major 1 — user-facing docs state the stateless per-Write limit

The changeset and USER-GUIDE described the guard as covering "catastrophically
shrinks" with no caveat, while the stateless design was disclosed only in the
hook header — an operator reading the shipped docs would conclude iterative
erosion is covered. Both surfaces now state the per-Write comparison and the
erosion non-goal explicitly, in line with what the guard does.

* fix(#2255): round 10 Blocker 1 — arm the hatch in the roadmapper's curated writes

gsd-roadmapper Step 7 Writes both .planning/ROADMAP.md and .planning/STATE.md
wholesale, and /gsd:new-milestone spawns it against the OUTGOING milestone's
files. new-milestone's `phases.clear` archives phase DIRECTORIES, never
ROADMAP.md, so nothing compacts it first, and no ordering rule forces
/gsd:complete-milestone to run before /gsd:new-milestone.

Measured against the shipped hook at the #973 file size (292 lines): a new
4-phase roadmap lands at 18.2% and an 8-phase one at 31.8% — both blocked; only
a 12-phase replacement (45.5%) clears. So the collapse is reachable on a
first-party flow, which is the failure mode #2255 para 4 says the guard must not
have.

Arms the single-use sentinel immediately before each Write, one per target
(the token is path-bound and single-use, so one arming cannot cover both), and
gates each arming on `[ -f ]` so the /gsd:new-project path — where the guard
already exempts via ENOENT — strands no unconsumed token.

Binding test derives the sentinel name from the guard's own typed output, so a
rename on either side fails the suite instead of silently unwiring the hatch.
Negative-controlled: 2 assertions fail against the pre-fix roadmapper.

* docs(#2255): round 10 Major 2 — scope the claim to the guarantee that ships

The sentinel is a plain file, so an agent that would reason past an advisory
can arm one with a single Bash call it is already permitted to make. The
"only defense independent of per-agent tool config" framing outran that, and
the changeset was on its way into CHANGELOG.md.

Retitles the claim on all three surfaces (changeset, guard header, USER-GUIDE)
to what the guard actually delivers: it blocks accidental and single-shot
collapse and is not a defense against a determined agent; what it converts is
"ignore a sentence" into "take one deliberate, path-bound, single-use,
auditable action".

Pinned by test on the DURABLE surfaces only — the guard header and USER-GUIDE.
The changeset fragment is deliberately not pinned: it is consumed at release,
so a test reading it would start failing the moment the release lands. The
bound-statement assertion normalizes comment markers and whitespace first, so
it pins the claim rather than the paragraph's line wrapping.

Negative-controlled: both assertions fail against the pre-fix surfaces.

* test(#2255): acknowledge the roadmapper growth from the round 10 Blocker 1 wiring

The emitted-attribution gate (#2719/#2767) flags gsd-roadmapper.md growing 1130
bytes without an acknowledgment. The growth is the Blocker 1 sentinel wiring
plus the rationale a future editor needs to keep it, so it gets an ack fragment
rather than a silencing regen — the gate's own message is explicit that there is
nothing left to regenerate.

Fragment is PR-scoped (2301-…) per the gate's naming instruction, and uses the
plain-string reason form the shipped fragments use.

Verified against the TRUE upstream tip, not the fork's origin/next: a stale
origin made this same gate report unrelated phantom drift (1 emitted path + 6
grown files + 5 stale acks) that vanishes when GSD_EMITTED_BASE is pinned.

* test(#2255): renumber the roadmapper PROSE_ALLOWLIST pin after the Step 7 wiring

CI red on shard 2/3, all four platforms. The #2751 gate keys PROSE_ALLOWLIST on
{file, line}; the Blocker 1 wiring added 18 lines above the allowlisted
parenthetical in agents/gsd-roadmapper.md, moving it 624 -> 642. Both halves of
the gate then fired: the moved line reads as a new offender, and the stale
entry no longer matches anything.

Line content at 642 is byte-identical to what the entry describes — a
descriptive "e.g." naming SDK queries a user could run — so this is a
renumber, not a re-classification.

Swept the defect class rather than the instance: agents/gsd-roadmapper.md is
the only line-pinned reference to any file this round changed.

Negative-controlled: both assertions fail against the un-renumbered allowlist.

cc3ee301a7 fix(#2544): stage the CommonJS marker in GSD-owned dirs, not the config root (#2593)
* fix(#2544): stage the CommonJS marker in GSD-owned dirs, not the config root

installSharedHooksBundle wrote `{"type":"commonjs"}` over
<configRoot>/package.json unconditionally — no existence check, no merge,
no backup — on every install and every /gsd-update re-install. On the 11
affected runtimes that file is often user-owned; on OpenCode and Kilo it is
the documented place to declare local-plugin npm dependencies, so a user's
name/type/dependencies/scripts were destroyed on each run.

The uninstall path already read the file and unlinked it only on an exact
content match. That asymmetry was the defect: the discipline existed in the
codebase, it just was not applied on the write side.

Move the marker into the directories GSD creates and fills with its own .js
files — hooks/ (all shared-hooks runtimes, incl. Kimi's own root) and the
nativePlugin dir (plugins/ for OpenCode+Kilo, extensions/ for pi) — and stop
writing the config root entirely. New src/commonjs-marker.cts owns the marker
string plus one ownership predicate (absent / gsd-owned / foreign, fail-closed
on an unreadable file) shared by ensureCommonJsMarker and removeCommonJsMarker,
so install and uninstall cannot drift apart again.

Nothing else depended on the config-root marker: package identity is baked at
build time (#378/#498) and version resolution prefers gsd-core/VERSION and
already tolerates a missing root package.json (#1383) — Codex has installed
without one all along. A package.json in plugins/ or extensions/ is inert to
plugin discovery, which globs *.{ts,js} only (see installer-migration 006).

Uninstall retires the pre-fix config-root marker, so upgrading users are
cleaned up on removal, and still never touches a file it did not write.

* fix(#2544): point the changeset fragment at the filed PR

The fragment's `pr:` field is only knowable after `gh pr create` returns.

* fix(#2544): register commonjs-marker.cjs in the tsc-generated ESLint ignore set

bin/lib/commonjs-marker.cjs is tsc output (src/commonjs-marker.cts is the
linted source), so it belongs in the ADR-457 ignore list like its siblings.
Clears the lint-tests no-var failure and the repo-invariants
"linted xor ignored" migration-state test.

* fix(#2544): pin the kimi CommonJS marker to hooks/, not the ~/.kimi root

The UPGRADE 1 test still asserted the pre-#2544 marker location
(~/.kimi/package.json). The marker now lives inside ~/.kimi/hooks — the
directory GSD itself creates — matching the updated golden-install-parity
and install-tree fixtures. Also asserts the root marker is NOT written.

* fix(#2544): make the CommonJS marker write path non-fatal

Review round 2, Major 3 + Minor 1 + the stagedHooks nit.

ensureCommonJsMarker rethrew any non-EEXIST write error and neither call site
caught it, so EACCES on a read-only hooks/, EROFS, or ENOSPC aborted the whole
install with a raw stack trace. Every other marker interaction in the module is
best-effort — removeCommonJsMarker swallows unlink failures, classifyMarker
swallows read failures — and this was the write path, i.e. the one most likely
to fail on a locked-down config dir. It now returns a new 'failed' outcome and
both call sites warn and continue.

Sibling found while sweeping for the same defect class: fs.mkdirSync sat
OUTSIDE the try block, so an unwritable parent threw past the guard entirely.
Creating the directory is the same environmental hazard as writing into it, so
it moved inside.

Also in this file:

- The hooks marker is now gated on `stagedHooks && hooksOk`, not stagedHooks
  alone. stagedHooks is computed from the SOURCE listing before the copy loop,
  so it stays true when the copies land but verifyInstalled() then fails —
  marking a hooks/ GSD did not successfully populate claims an ownership the
  install did not earn.
- The uninstall rmdir of the native plugin dir is gated on GSD having actually
  removed something from it. Hoisting it out of the adapter-exists guard (so
  the marker-only case could prune) had silently widened it into deleting a
  user-created but empty plugins/ or extensions/ dir — the same "don't touch
  territory GSD didn't fill" principle this issue is about, inverted.
- Kimi's pre-#2544 marker at its native hook root (~/.kimi) is retired at the
  same call site that writes its replacement. That path is outside kimi's
  configDir, so installer-migration 007 structurally cannot reach it.

* fix(#2544): retire the stale config-root marker via installer-migration 007

Review round 2, Major 1 — the PR's headline claim was false for existing
installs. Upgraders kept BOTH markers: the new one under hooks/ and the stale
{"type":"commonjs"} at the config root, so their config root stayed pinned to
CommonJS and their dependency manifest stayed gone until they uninstalled.

The migration is unusual in one way, and it is the part worth reviewing: the
config-root marker was never recorded in gsd-file-manifest.json (writeManifest
records hooks/, agents/, commands/, scripts/ and the native plugin, never a root
package.json), so classifyArtifact answers 'unknown' for it and the planner's
own guard downgrades a remove-managed on an 'unknown' classification to
preserve-user. 007 therefore supplies the "purpose-built detector for an old
GSD-owned shape" that docs/installer-migrations.md#remove-managed sanctions —
exact content match, the same predicate removeCommonJsMarker has always used —
and declares the resulting classification on the action. A package.json with any
other content is left untouched, and there is deliberately no backup-and-remove
branch: a non-matching file here is not a patched GSD artifact, it is somebody
else's file.

Scope is all runtimes. The `runtimes` field is OMITTED rather than `[]`:
validateStringArray requires the field to be non-empty WHEN PRESENT, while the
runtime filter treats an empty array as "all" — so `runtimes: []` throws at plan
time and the migration never runs. The metadata test pins this.

Kimi is a deliberate carve-out, named in the migration's own header: its marker
lived at ~/.kimi, outside kimi's configDir, and migration relPaths are
structurally confined to configDir. It is retired by the installer instead.

Registration: shipped-migrations table, .gitignore for the emitted .cjs, the
EXPECTED_CHECKSUMS baseline, and the ESLint ignore set. That last one is not
copied from migration 006 by rote — 006 needs no entry because it imports
nothing, while 007 imports node builtins, so tsc emits its __importDefault
helper and the `var` in it trips no-var. This is the same lint gate that made
round 1 red.

* test(#2544): fault-injection and multi-runtime marker coverage

Review round 2, Major 2 + Minors 4 and 5.

Major 2 — CONTRIBUTING.md:514-531 is mandatory for install/uninstall flows and
the suite had no fs monkeypatching at all. Every branch now covered is one whose
doc comment claims it as the module's safety posture:

- classifyMarker non-ENOENT lstat error -> 'foreign' (the fail-closed rule),
  with an ENOENT control alongside it so the test discriminates rather than
  just asserting one side
- classifyMarker readFileSync throw -> 'foreign' (present-but-unreadable never
  downgrades to the permissive answer) — the fixture's bytes are exactly GSD's
  marker, so the test fails if the code ever answers on content it could not read
- a DIRECTORY at the marker path (CONTRIBUTING:521; the symlink case was already
  covered with a real symlink, the directory case needs no injection at all)
- the ensureCommonJsMarker TOCTOU EEXIST branch — the entire reason for flag:'wx'
- the new 'failed' outcome, for both writeFileSync (EACCES/EROFS/ENOSPC) and the
  mkdirSync that used to sit outside the guard
- removeCommonJsMarker unlink throw -> false

These save and restore fs methods in `finally` rather than using chmod 0o000,
which does not fault under root and would pass vacuously in root Docker and CI.

Minor 4 — uninstall was driven for opencode only. pi's extensions/ and both
kimi locations now have behavioral coverage, install and uninstall, each paired
with a user-authored-file case proving GSD leaves it alone.

Minor 5 — the stagedHooks gate had no assertion behind its stated reason.
A pre-existing, GSD-untouched hooks/ directory is now driven through a runtime
that declares skipSharedHooksInstall and asserted to stay marker-free, with its
user content intact.

Also regression-tests the uninstall rmdir gate from the previous commit: an
empty plugin dir GSD removed nothing from must survive.

* docs(#2544): correct stale marker prose, register the module, document the trade-off

Review round 2, Minors 2, 3 and 6.

Minor 2 — six files asserted the installed ROOT ships the synthetic marker.
None was load-bearing (all three walk-up consumers are VERSION-first with
try/catch and the marker never carried a `version`), but ADR-457:52 is the
rationale for keeping a generated module, so a future reader would mis-derive
the constraint from it. Each site is corrected to what is now true: the
installed tree carries no package.json with a .name at all, because the only
ones GSD stages are {"type":"commonjs"} markers and they now live in GSD's own
directories.

Two of the six needed more than a location swap. hooks/gsd-check-update-worker.js
and the platform-gate test both described `require('../package.json').name`
resolving to undefined; post-#2544 that require does not resolve at all, so the
history is kept accurate and the present-tense claim corrected rather than just
moved. And src/runtime-artifact-conversion.cts described the no-root-package.json
case as Codex-only — it is now every runtime, which strengthens that comment's
own argument for lazy resolution. The generated .cjs sibling needs no edit: it
is gitignored build output, not a tracked file.

Minor 3 — src/commonjs-marker.cts had no CONTEXT.md entry, unlike every peer
module, and CONTEXT.md is the #2 co-change partner of bin/install.js. Added,
including the fail-closed posture and the never-throws contract.

Minor 6 — the plugins//extensions/ marker shadows the config root for all .js
siblings, so an OpenCode/Kilo user's ESM plugin/*.js stays broken. That is
exactly what #2544's Fix section prescribed and it is disclosed in the PR body,
but the PR body is not documentation. It now lives in the OpenCode section of
docs/how-to/install-on-your-runtime.md, stated as a real constraint rather than
a pure improvement, with the .ts mitigation and a fallback for ESM plugins.

* test(#2544): attribute the CommonJS marker in the emitted-provenance rules

The differential emitted-attribution gate (#2723, landed on `next` after this
branch was cut) went red on the macOS shards once this PR rebased onto it. Two
distinct causes, both real gaps rather than noise:

1. `plugins/package.json` and `extensions/package.json` matched NO rule — the
   `native-plugin` rule covers `*.{js,cjs,mjs}` only, so the marker read as an
   unattributed emitted family.
2. `hooks/package.json` fell through to `hooks-built`, which attributes an
   emitted `hooks/<X>` to a repo source `hooks/<X>`. There is no
   `hooks/package.json` in the repo, so it resolved to a nonexistent path.

Cause 2 is exactly the failure already documented three lines above it for
Copilot's `gsd-session.json` — "a code literal, not a built script" — so the fix
follows that precedent rather than inventing one: `package.json` is excluded
from `hooks-built` the same way, and a dedicated `commonjs-marker` rule
attributes the family across all four roots it can appear in (both hooks roots
plus `plugins`/`extensions`) to the sources that actually emit it.

Deliberately a RULE, not an entry in tests/emitted-drift-ack.json. An ack is for
a one-off ripple and goes stale by design — the gate fails a stale ack precisely
so it cannot pre-clear the next change on that path. These markers are a
permanent part of the emitted tree from #2544 onward, so they need standing
attribution.

Verified by reproducing the CI failure locally with GSD_EMITTED_BASE: 3
provenance errors + 12 unattributed paths before, 35/35 green after.

* fix(#2544): route the #2717 hooks-surface marker helpers through commonjs-marker

#2717 landed a second copy of ensureCommonJsMarker/removeCommonJsMarkerIfGsdOwned
in src/runtime-hooks-surface.cts for the runtimes that stage .js hooks via
dedicated paths (cursor/windsurf/codex). That copy had drifted from this PR's
module on the two properties that matter:

  - ownership probe: `fs.existsSync` FOLLOWS symlinks and reports false for a
    DANGLING one, so a dangling package.json symlink classified as absent and
    the write went straight through it. Demonstrated: against the pre-fix copy,
    ensureCommonJsMarker() on a hooks/ dir holding a dangling package.json
    symlink returns true and creates {"type":"commonjs"} OUTSIDE that directory.
  - create: a plain writeFileSync leaves the classify->write window open, where
    commonjs-marker creates with flag:'wx' (O_EXCL).

Both helpers now delegate to src/commonjs-marker.cts, which is what this PR's
own docstring already claimed was the single place these rules are enforced.
Exported signatures are unchanged (still boolean), so bin/install.js and the
#2717 tests are unaffected.

The new subtest is the only coverage that fails if the duplicate is ever
reintroduced — the two implementations agree on every non-adversarial input, so
the existing suites pass against both.

* test(#2544): pin the stagedHooks gate on zcode, not windsurf

The Minor-5 coverage picked windsurf because hostBehaviors.skipSharedHooksInstall
kept it out of the shared hooks bundle, so GSD staged nothing into hooks/ and the
marker was correctly absent.

#2717 changed that premise: cursor/windsurf/codex now stage their .js hooks via
dedicated paths and get the marker beside those scripts. Measured on this tree,
windsurf stages 2 .js hooks and receives a marker — so the assertion was pinning
behaviour that is now wrong, not the gate it was written for.

ZCode is the durable choice: per #1821 it has hooksSurface:'none' AND no plugin
surface to spawn hooks, so GSD stages no .js there by either route (measured: 0
staged, no marker). The property under test is unchanged — a user-created hooks/
directory GSD never fills stays marker-free.

* test(#2544): use the shared cleanup helper in the migration test

Addresses the review's Major 1. The suppression's stated reason — "no helpers
import available" — was not correct: tests/helpers.cjs exports cleanup, and the
other test file added in this same PR imports it (tests/commonjs-marker.test.cjs).

The local reimplementation dropped two protections that are live on this repo's
windows-latest lane: the CWD guard (Windows cannot remove a directory that is the
current working directory) and the 20 x 250ms retry budget that absorbs the
deferred-scan handle Windows Defender holds on newly-written files.

Local function and suppression both removed; local/no-raw-rmsync-in-tests now
passes without one.

* test(#2544): expect hooks/package.json for the #2717 runtimes

The fresh-install contract table predates #2717, which stages cursor/windsurf/
codex .js hooks via dedicated paths and writes the CommonJS marker beside them.
All three therefore now receive hooks/package.json legitimately.

Measured on this tree: codex stages 3 .js hooks, cursor 6, windsurf 2 — each with
the marker; cline/copilot/trae/zcode stage none and get none, so their contracts
are unchanged.

* fix(#2544): gate the #2717 marker writes on having staged something

The three dedicated marker writers #2717 added ran unconditionally. Each one
mkdirs hooks/ up front and stages its scripts conditionally on the source
existing, so with an absent or empty hook source they created a directory,
filled it with nothing, and marked it as GSD's anyway.

That is the same write-into-someone-else's-territory this issue is about, and
installSharedHooksBundle already guards the identical case with `stagedHooks`.
The dedicated paths now carry the matching gate:

  - cursor / windsurf: `installedScripts.size > 0`
  - codex: a new `codexStagedHooks` flag. The enclosing guard only proves that
    hooks/dist EXISTS; it says nothing about whether any CODEX_HOOKS_TO_COPY
    entry landed.

Covered for cursor and windsurf by driving each writer against a src tree whose
hooks/ dir is empty. The codex leg is defensive and deliberately uncovered: its
trigger state needs a package tree where hooks/dist exists but holds none of the
allowlist, which is not constructible from a real checkout.

* test(#2544): scope the commonjs-marker sources per root

The rule declared one flat source list for every marker root, so
`extensions/package.json` was attributed to runtime-hooks-surface.cts (which
never writes there) and `.kimi/hooks/package.json` to install-engine.cts.

That is not merely untidy. emitted-diff.cjs accepts the FIRST satisfied source,
so a flat list containing bin/install.js let any change anywhere in that
13k-line file authorise marker drift for every root — the blanket escape hatch
this file's own agents-verbatim comment refuses for exactly the same reason.

Sources are now derived per root from ctx.rel. Note the rule ctx is
`{ rel, runtime }` and carries no `root`, so keying on ctx.root would have sent
every path down one branch silently.

* test(#2544): state precisely what the zcode assertion pins

The comment claimed the test pinned installSharedHooksBundle's `stagedHooks`
gate. It does not, and neither did the windsurf version it replaced: zcode
declares skipSharedHooksInstall, so the outer guard skips that helper entirely
and the gate is never evaluated. The test passes on the runtime exclusion.

What it does pin — the outcome a pre-existing, GSD-untouched hooks/ stays
marker-free — is still worth having, and is what the review asked for. The two
`staging zero hook scripts` tests are the ones that pin a real staged-nothing
gate. Comment corrected rather than left implying coverage that is not there.

4f6935e29b fix(#2717): write CommonJS marker for cursor/windsurf/codex staged .js hooks (#2846)
* test(#2717): CommonJS marker for cursor/windsurf/codex staged .js hooks

Cursor/windsurf (skipSharedHooksInstall) and codex (!isCodex gate) stage .js
hook scripts via dedicated paths that bypass installSharedHooksBundle — the
only writer of the {"type":"commonjs"} marker. Under a config root declaring
{"type":"module"}, Node loaded those scripts as ESM and every require()
failed with 'require is not defined', silently disabling the runtime's hooks.

Adds regression tests (RED first, fix lands next commit):
- parametrized cursor/windsurf/codex install asserts hooks/package.json exists
  with exactly GSD's marker content;
- end-to-end: a cursor require()-using hook loads under a planted ESM-typed
  config root without the require-is-not-defined error;
- the ensureCommonJsMarker / removeCommonJsMarkerIfGsdOwned contract: GSD
  markers are removed on uninstall, user-authored package.json is never touched.

* fix(#2717): write CommonJS marker for cursor/windsurf/codex staged .js hooks

The {"type":"commonjs"} marker lived only inside installSharedHooksBundle,
which cursor/windsurf (skipSharedHooksInstall) and codex (!isCodex gate) never
reach. Their .js hooks are staged by dedicated paths, so under a config root
declaring {"type":"module"} Node loaded them as ESM and every require()
failed with 'require is not defined', silently disabling those runtimes' hooks.

Decouple the marker write into a shared helper so any code path that stages
.js hooks can ensure it lands in the SAME directory as the scripts:

- src/runtime-hooks-surface.cts: add ensureCommonJsMarker(dir) +
  removeCommonJsMarkerIfGsdOwned(dir) (byte-identical content to
  installSharedHooksBundle's marker; preserves a user-authored package.json on
  both write and uninstall). Call ensureCommonJsMarker(hooksDir) from
  writeCursorHooksJson + writeWindsurfHooksJson; call
  removeCommonJsMarkerIfGsdOwned on their matching remove paths. Export both.
- bin/install.js: call hooksSurface.ensureCommonJsMarker after the codex hook
  copy; call hooksSurface.removeCommonJsMarkerIfGsdOwned in the generic
  hooks-removal loop (safe no-op where no marker exists).

No change to which runtimes receive the shared bundle, the !isCodex gate,
skipSharedHooksInstall, or kimi/kimi-code/cline/copilot/trae/zcode (all
unchanged — audit in the diagnosis). RED @ dbb7d2bb (6 failures: 3 missing
markers + the ESM require error + missing helpers); GREEN pending.

* docs(#2717): changeset fragment (pr:0, backfilled post-PR)

* chore(#2717): regen codex/cursor/windsurf install-tree fixtures + attribution ack

The fix adds hooks/package.json to those three runtimes' install trees (the
new CommonJS marker), so the golden install-tree fixtures gain one path each
(regenerated via npm run gen:install-tree). emitted-attribution (ADR-2719)
flags the 3 emitted hooks/package.json paths under the hooks-built rule;
acknowledge them. Also drops 5 spent ack entries left by now-merged PRs
(#2694 code-review.md/code-review-fix.md, #2695 worker/registry, #2794
review.md) — they are stale on this branch (base already carries them).

* fix(#2717): codex ESM-root behavioral test + hooks-built provenance for package.json

Two review-driven follow-ups on the #2717 fix:
- Adversarial review noted the ESM-root behavioral test covered only cursor;
  refactor it into a helper and add a codex case (the !isCodex-gated path most
  likely to regress, whose marker write lives in bin/install.js). gsd-check-update.js
  require()s at module load, so it surfaces the ESM failure immediately.
- emitted-provenance flagged hooks/package.json as 'attributed source does not
  exist' — the marker is code-derived (a fixed literal emitted by
  ensureCommonJsMarker at install time), not built from a tracked source. Route
  the hooks-built rule's sources/transforms for package.json to the surface
  source file, mirroring the existing .cmd-shim sub-family.

* chore(#2717): drop now-redundant hooks/package.json attribution ack

The hooks-built provenance routing (prior commit) now self-attributes the
emitted hooks/package.json to src/runtime-hooks-surface.cts, which IS in this
diff — so the attribution is self-explaining and the emitted-drift-ack entry
became stale. Delete the (now-empty) ack file per ADR-2719's empty-file rule.

c7c2fe3c2b fix(#2587): resolve cursor hook workspace from workspace_roots, not cwd (#2680)
* fix(#2587): resolve cursor hook workspace from workspace_roots, not cwd

gsd-cursor-session-start.js and gsd-cursor-stop.js both resolved the project as
path.join(process.cwd(), '.planning', 'STATE.md'). Under the cursor-agent CLI,
hooks are invoked with cwd set to the Cursor config dir (~/.cursor), not the
workspace — so the lookup always missed. sessionStart could only ever emit the
"no .planning/ workflow found" nudge and stop's verify-work reminder could never
fire, even with .planning/STATE.md sitting in the workspace. Slash commands were
unaffected, which is why only the hook layer looked blind.

Both hooks already buffered stdin into `raw` and never parsed it; the payload's
workspace_roots carries the real path.

Multi-root was left open in the report ("first root vs any root"). Resolved
forward: prefer the first root that actually carries .planning/STATE.md, so a
workspace whose GSD project is not the first root still resolves — strictly
better than first-root-only and identical to it in the single-root CLI case.
Falls back to roots[0], then to cwd, keeping IDE behavior unchanged if the IDE
ever invokes hooks from the workspace.

The resolver is duplicated verbatim across the two scripts rather than shared via
hooks/lib/: these hooks ship standalone, and a new hooks/lib/ file must be
registered in the GENERATED installer's GSD_HOOK_LIB_FILES allowlist — the
installer-omits-shipped-file class that yields MODULE_NOT_FOUND at runtime. Per
CLAUDE.md "Generative Fix Divergence", the duplication carries a parity assertion
so the copies cannot drift.

Failing-first, demonstrated by direct invocation with cwd != workspace:
  pre-fix  sessionStart -> "no .planning/ workflow found"   stop -> {}
  post-fix sessionStart -> ".planning/STATE.md is present"  stop -> reminder

tests/fix-2587-cursor-hook-workspace-roots.test.cjs spawns the real scripts as
child processes with a cwd lacking .planning/ and workspace_roots pointing at it.
Boundary coverage on the roots array (0 / 1 / 2 entries), plus malformed-JSON
fail-open, junk-entry filtering, the parity assertion, and a guard that neither
script resolves .planning from cwd again.

* fix(#2587): extend workspace_roots fix to subagentStart; keep cwd a candidate

Three findings from the isolated review, all fixed.

1. MISSED SITE (high). gsd-cursor-subagent-start.js carried the identical
   defect at line 43 — its own header documents workspace_roots in the input
   schema, but it resolved .planning/ from process.cwd() anyway. Under the
   cursor-agent CLI that meant every Cursor subagent (planner, executor,
   verifier) started with "no .planning/ workflow found" and no phase context.
   The report named only sessionStart and stop; the defect class was wider.
   Verified pre-fix vs post-fix by direct invocation with cwd != workspace.

2. SEMANTIC NARROWING (medium). The first cut searched only workspace_roots and
   fell back to cwd solely when the array was EMPTY. So when roots were supplied
   but none carried .planning/ while cwd did, the hook reported absent — where
   the pre-fix code, which always used cwd, reported present. That contradicted
   the fallback's own stated intent of preserving IDE behavior. cwd is now a
   CANDIDATE in the search (`[...roots, process.cwd()]`), so the fix is a strict
   superset of both the old behavior and the CLI fix, never a narrowing.

3. STALE GOLDEN FIXTURES (high, would have failed CI). The golden-install-parity
   fixtures store a content hash per installed file; these three hooks appear in
   13 of the 19 runtime fixtures. Regenerated via `npm run gen:golden` — the
   diff is exactly the three hook hashes in exactly those 13 runtimes.

Tests extended: subagentStart resolution via workspace_roots; the stop hook's
absent branch (previously only session-start's was covered); an explicit
regression guard that a project at cwd is still found when roots miss; parity now
asserts all THREE copies byte-identical; and the cwd guard sweeps the whole
RESOLVING_HOOKS list so a future hook in this family cannot be left on cwd.

* refactor(#2587): extract cursor workspace resolution to a shared hooks/lib module

The duplicate-plus-parity-test approach was the wrong call. The reported issue
named two hooks; a third (subagentStart) had the identical defect. That is the
signature of a systemic problem, and three copies of a resolver guarded by a
parity assertion is a divergence risk maintained by hand rather than a fix.

hooks/lib/cursor-workspace.js is now the single implementation. All three Cursor
hooks require it; none defines a local copy. Divergence is prevented
structurally instead of by asserting three copies stay byte-identical.

The reason duplication looked necessary was real, and is fixed properly here
rather than worked around: Cursor sets hostBehaviors.skipSharedHooksInstall
(#2089), so it never reaches the installer's bulk hooks/lib copy — it was the
ONE runtime shipping these hooks WITHOUT hooks/lib (verified against all 19
golden fixtures: cursor had the hook scripts, no lib). A naive require would
have thrown MODULE_NOT_FOUND at load, BEFORE each hook's own try/catch, wedging
every session on precisely the runtime this bug is about.

writeCursorHooksJson (src/runtime-hooks-surface.cts) now stages the hooks/lib
helpers the staged scripts actually require, discovered by scanning their
require('./lib/…') calls rather than a hardcoded name — so a future helper
cannot be silently omitted. This is narrower than flipping
skipSharedHooksInstall, which would wrongly pull in every shared hook.
cursor-workspace.js is also added to GSD_HOOK_LIB_FILES so uninstall and the
manifest manage it for the runtimes that do receive hooks/lib.

Verified against a REAL install (runMinimalInstall, cursor/global): the helper
is staged, and all three INSTALLED hooks resolve the workspace end-to-end from a
cwd that is not the project.

Also closes the review gap that the stop hook was excluded from the
cwd-candidate regression loop — it now sweeps RESOLVING_HOOKS. The byte-parity
test is replaced by a structural guard (every hook requires the shared module,
none redefines it) plus a new install test asserting the helper is staged and
the installed hook actually loads against it.

* fix(#2587): fail loud on a missing hook lib source; drop unsubstituted version marker

Two findings from the installer-focused review.

H1 — the staging step's `if (!fs.existsSync(libSrc)) continue;` silently defeated
the very guarantee it was added for. Reproduced: delete hooks/lib/cursor-workspace.js
from source, run the cursor install — it exits 0, prints "Done!", and ships the
three hook scripts with an EMPTY hooks/lib/. The installed hook then throws
`Cannot find module './lib/cursor-workspace.js'` at load, before its own
try/catch, wedging every session — and nothing surfaces until a user hits it.
The scan protected against a required-but-UNLISTED helper while leaving
required-but-MISSING wide open (typo, bad rebase, an accidental delete).
It now throws: a missing helper source is a packaging bug and aborts the install.

M1 — hooks/lib/cursor-workspace.js carried a `gsd-hook-version: <placeholder>`
marker that NOTHING substitutes: copyLibDir stamps .sh files only, and
writeCursorHooksJson's staging applies just the colon-to-dash rewrite. Verified
the literal was reaching disk on both the bulk (--claude) and Cursor
(--cursor) paths. hooks/lib/git-cmd.js — the only pre-existing hooks/lib/*.js —
carries no such marker, so this was newly introduced, not inherited. Marker
removed, matching that precedent, with a note on why. (The explanatory comment
deliberately does not spell the token out, or it would reintroduce the literal.)

M2 — the require-scan regex demanded the exact compact form, so
`require( "./lib/x.js" )` would silently fail to stage its helper and compound
H1. Now tolerant of interior whitespace and either quote style.

Regression test added for H1 — the reviewer confirmed the invariant had zero
coverage repo-wide: a source tree carrying the hooks but no hooks/lib/ must make
writeCursorHooksJson throw rather than produce a broken install.

Re-verified end to end: the missing-source case throws, no unsubstituted literal
ships, and the installed hook still resolves the workspace from a foreign cwd.

dcb4954131 fix(#2335): normalize volta node image paths to the stable shim (#2375)
Adds a volta branch to normalizeNodePath() that rewrites the version-pinned node image path to volta's stable shim, so managed hooks survive a volta node prune (the fnm/Homebrew/mise class, now covered for volta). Also unifies the release-smoke install timeout into one shared 600s constant across before() and runSmoke() so slow benches no longer spuriously time out.

Closes #2335. Admin-merged (self-review bypass) with full green CI.

e35534c3ec fix(#2236): add hookShell parameter for PowerShell call operator (#2261)
* fix(#2236): add hookShell parameter for PowerShell call operator

Windows Claude Code with a PowerShell hook runner failed on every hook
with 'Unexpected token' — the installer emitted bare quoted paths that
PowerShell parses as string literals, not commands.

The root cause was that hookCommandNeedsPowerShellCallOperator returned
false unconditionally — the &/no-& decision was keyed on (platform,
runtime) only, with no signal for the effective hook-execution shell.
One runtime (Claude Code) hosts either Git Bash or PowerShell on Windows.

Fix: thread a new hookShell parameter through the projection chain.
When hookShell='powershell', the & call operator is prepended. Default
(Git Bash, no prefix) is unchanged and regression-locked.

e0f969af6a refactor(#2246): centralize cross-platform path-separator handling (toPosixPath / toNativePath / posixNormalize) (#2247)
Replace every open-coded separator translation across the installer/hooks
source with named, tested seams in shell-command-projection.cts (the platform
seam), removing all hardcoded `/`+`\` from path handling:

- toPosixPath(p)   — this machine's native path → POSIX (running-OS relative;
                     for local filesystem paths).
- toNativePath(p)  — POSIX → native (collapses the win32 `/\//g,'\\'` ternary).
- posixNormalize(p)— unconditional `\`→`/`, OS-independent; for emitting paths
                     to a POSIX/bash TARGET (which may differ from the running
                     OS) and for parsing mixed-separator input.

core-utils.toPosixPath now delegates to the seam, so its 20+ existing consumers
resolve to one implementation; no duplicate helper.

- ~47 sites across runtime-hooks-surface, runtime-artifact-conversion,
  runtime-artifact-install-plan, drift, init, worktree-safety,
  installer-migrations, installer-migration-authoring, install-engine, surface,
  verify, runtime-artifact-layout, schema-detect, check-command-router.
- Closes the latent POSIX-literal-backslash corruption class (the regex form
  corrupts a POSIX path containing a literal backslash; split(path.sep) does not).
- New unit + fast-check property tests for all three helpers.

Closes #2246

7baabad146 fix(#2185): normalize Linuxbrew + any Homebrew Cellar path to the stable symlink
normalizeNodePath had hardcoded branches for macOS Intel (/usr/local/Cellar) and
Apple Silicon (/opt/homebrew/Cellar) but none for Linuxbrew
(/home/linuxbrew/.linuxbrew/Cellar). After `brew upgrade node` on Linux, the
version-pinned Cellar path baked into managed hook commands 404'd, and re-running
the installer did not repair it — normalizeNodePath returned the pinned path
unchanged, so the 'already normalized' skip-rewrite check no-op'd.

Generalize to one branch: match <prefix>/Cellar/node(<@ver>)?/<ver>/bin/node and
rewrite to <prefix>/bin/node, deriving <prefix> from the path itself. This covers
macOS Intel, Apple Silicon, Linuxbrew, and any custom HOMEBREW_PREFIX — the same
failure class as #977 (fnm) and #1619 (mise), now closed for Homebrew on every
platform.

bd613566cb feat(#2100): drive Windsurf through the EoS descriptor + wire Cascade's blocking hook bus (ADR-1239)
Fold all 10 residual isWindsurf branches in bin/install.js onto descriptor-driven
hostBehaviors (byte-parity — no fold changes any install output):
- 2 dead destructures dropped (uninstall, finishInstall); the dead
  `else if (isWindsurf)` legacy agent-loop arm removed (windsurf ∈
  _DESCRIPTOR_AGENTS_RUNTIMES → unreachable).
- skipSharedHooksInstall:true folds the two `!isWindsurf` shared-hooks exclusions.
- legacyDevinSkillsCleanup:true folds the `.devin`→`.windsurf` one-time cleanup gate.
- installsCommandBodiesForWorkflowDelegation:true folds the #1629 command-body copy
  (workflow-delegation target — load-bearing; local-install verified intact).
- verificationStyle:"windsurf-workflows" folds the workflow-count report.
- Corrected stale _LEGACY_SCAN_SUBDIR_NAMES + hooks-json manifest comments (cursor + windsurf).
Zero live runtime==='windsurf'/isWindsurf branches remain across bin/install.js,
install-engine.cts, surface.cts, runtime-artifact-conversion.cts (AC2 guard scans all four).

UPGRADE (Cascade hook bus): wire GSD's write/command safety guards into Windsurf's
native hook bus. New hooksSurface 'windsurf-hooks-json' (VALID_HOOKS_SURFACES 7→8, GATE A
profile-marker-only allowlist, the HooksSurface union) + writeWindsurfHooksJson
(Cursor-templated, Cascade's flat {hooks:{<event>:[{command}]}} shape) writing
.windsurf/hooks.json with two BLOCKING pre-hooks:
- pre_write_code → gsd-windsurf-pre-write.js: blocks writes to a file outside the
  active git worktree / into .git internals.
- pre_run_command → gsd-windsurf-pre-command.js: conservative destructive-command
  deny-list (rm -rf of root/home incl. sudo/env/path-prefixed forms; fork bombs;
  force-push refspec forms — HEAD:main, +main, --force/-f — to main/master/next).
Both use Cascade's protocol (stdin JSON, exit 2 + stderr to block, exit 0 to allow,
fail-open on error/timeout). Tokenize-based classifier (no catastrophic-backtracking regex;
4096-char cap) with the fail-closed false-positives fixed post-review.

The 4 advisory GSD guards + pre_mcp_tool_use + 5 post_* logging events are deliberately
NOT wired: Cascade has no context-injection channel for advisory hooks and GSD has no MCP
guard — porting them would be non-functional padding (documented; codebuddy #2098 / copilot
#2099 faithful-subset precedent). extendedHookEvents stays [].

Golden: the 2 guard scripts ship in the shared hook bundle (HOOKS_TO_COPY + the shared
managed-hooks-registry), exactly like cursor's 6 gsd-cursor-*.js scripts — so the 8
shared-bundle runtimes' fixtures gain the 2 inert windsurf scripts + the registry hash
(functionally inert for non-windsurf; the established cursor pattern). No install-output
change beyond that (the folds are byte-parity; skip-bundle runtimes untouched). New scripts
registered in managed-hooks-registry + build-hooks + INVENTORY. Tests: declarative-reference-
windsurf (adapter/axes/fail-closed + AC2 guard) + windsurf-hooks-bridge (live exit-2 blocking
+ allow/fail-open + ReDoS-bound + writer/reconcile/remove idempotency); VALID_HOOKS_SURFACES
pin updated to 8. Matrix hookBus delta + changeset (Changed). capability-registry regenerated.

d1e9491fef feat(#2099): drive GitHub Copilot through the EoS descriptor + multi-event hook bus (ADR-1239)
Fold Copilot's residual runtime-literal branches onto descriptor-driven
hostBehaviors. Several issue premises were inaccurate (verified via research)
and deliberately NOT followed: writesSharedSettings/"legacy exclusion list"
(per-runtime descriptor data, copilot's false is correct); RUNTIME_CONTENT_DISPATCH.copilot
+ installSurface==='copilot-instructions' (already descriptor-driven);
extendedHookEvents (closed Claude/Gemini enum — hooks extended in code instead);
reapply ternary (already folded, kimi #2095).

Real folds (all byte-parity — golden byte-identical for every runtime):
- src/install-engine.cts + src/surface.cts: the two `.agent.md` filename cutovers
  (_copyStaged + _syncGsdDir) unified onto hostBehaviors.agentFileExtension via a
  new exported agentFileExtensionFor() accessor (kills the two-mechanism divergence).
- src/runtime-artifact-conversion.cts: applyAgentPathRewrites' copilot skip →
  hostBehaviors.noPathRewrite:true (antigravity #2096 precedent).
- bin/install.js uninstall: the two isCopilot cleanup branches → installSurface===
  'copilot-instructions' gate (symmetric with install-time).
- bin/install.js: `!isCopilot` in the two skipSharedHooksInstall checks →
  hostBehaviors.skipSharedHooksInstall:true (copilot has no shared gsd-*.js hooks).
- bin/install.js: three dead legacy inline-agent-loop isCopilot refs removed
  (copilot ∈ _DESCRIPTOR_AGENTS_RUNTIMES → unreachable; byte-parity proven by clean
  golden + real reachable-runtime install diffs). isCopilot dropped from 4 destructures.
Zero live `runtime==='copilot'`/`isCopilot` branches remain in bin/install.js,
install-engine.cts, surface.cts, or runtime-artifact-conversion.cts (AC2 guard scans all four).

UPGRADE 1 (multi-event hook bus): buildCopilotHookConfig() now emits preToolUse/
postToolUse/userPromptSubmitted/sessionEnd advisory handlers alongside sessionStart
(static inline bash/powershell — deterministic, golden-trackable). Only copilot.json's
gsd-session.json hash changes.

UPGRADE 2 (background dispatch): surfaced via the negotiated contract only —
dispatch.background:true exceeds the declarative-cli baseline and survives negotiation
with no downgrade warning. NO .agent.md frontmatter field (copilot has none). MCP
companion out of scope (AC4 names only 2 upgrades).

Tests: declarative-reference-copilot (adapter/axes/fail-closed + AC2 4-file source-grep
guard) + copilot-upgrades (live 5-event hook wiring; dispatch.background negotiation).
Matrix EoS note + how-to; changeset (Changed). capability-registry regenerated.

Incidental flaky-test RE-ARCHITECTURE (no-defer, maintainer-directed):
tests/opencode-review-reconstruction.property.test.cjs spawned ~600 synchronous
execFileSync('jq') subprocesses (numRuns:200 × 3 fast-check properties, one jq per
generated stream); a single jq freezing on a contended macos-22 CI runner hung the whole
unit-test chunk to its 600s kill (this PR's CI). --test-force-exit can't interrupt a
synchronous execFileSync, so the cure is to stop spawning per case, not just time-bound
it. Re-architected to run the SHIPPED jq program over the whole fast-check corpus in ONE
jq process: each generated stream is one compact-JSON array per line in a temp file,
`jq -c <PROGRAM>` (no -s) applies PROGRAM to each array (`.` == the array, exactly what
production's `jq -rs <file>` sees after slurping) and emits one result per line —
empirically byte-identical to the per-stream form across embedded-newline/empty/quote/
unicode/null-drop cases, and file-input (like production) so there's no stdin pipe to
deadlock on large I/O. ~600 spawns → 6; coverage unchanged (200-case corpus per property,
deterministic seeds) plus explicit boundary/diagnostic example batches. Still property-
tests the real shipped jq (no JS reimplementation). Per-call jq timeout retained as a
belt-and-suspenders bound.

ab04916682 feat(#2095): migrate Kimi CLI onto EoS imperative adapter + native hook-bus + background dispatch (ADR-1239)
Fold all runtime==='kimi'/isKimi logic branches into descriptor-driven
hostBehaviors (localInstallDeferred, verificationStyle, agentManifestStyle,
reapplyCommand, doneBannerStyle) + add 'kimi' to _DESCRIPTOR_AGENTS_RUNTIMES.
Kimi's skills/kimi-agents dispatch was already descriptor-driven (converter-by-
name + kimi-agents kind). Zero isKimi/runtime==='kimi' branches remain.

UPGRADE 1 (native hook bus): new hooksSurface 'kimi-hooks-toml' + a marker-
delimited config.toml [[hooks]] emitter (buildKimiHooksTomlBlock/writeKimiHooksToml
in runtime-hooks-surface.cts; resolveKimiHooksTomlDir in runtime-homes.cts).
GSD's lifecycle hooks now wire into Kimi's native ~/.kimi/config.toml (Context7-
confirmed path) at SessionStart/PreToolUse/Stop/PreCompact/SubagentStart/
SubagentStop — kimi becomes a hooks/ consumer (the 3 && !isKimi exclusion guards
removed). config.toml holds absolute install paths so it's golden-excluded via
an exact relative-path (.kimi/config.toml), not a basename (which would blind
Codex's config.toml). New hooksSurface value added to the closed enum in
capability-validator + runtime-config-adapter-registry.
UPGRADE 2 (background dispatch): flip dispatch.backgroundDispatch true (Kimi's
Agent tool takes run_in_background; root agent already gets the Agent tool), so
negotiation no longer flattens dispatch. subagentToolkit stays 'undocumented'
per AC (coder/explore/plan have distinct tool policies).
MCP transport explicitly deferred (no installer-driven MCP for any runtime).

Golden: only kimi.json changes (hooks/ scripts now installed); all 15 others +
claude-local byte-identical (kilo/zcode keep their own exclusions). Tests:
kimi-imperative-reference (adapter/axes/fail-closed/hostBehaviors + source-grep
guard) + kimi-upgrades (config.toml [[hooks]] SessionStart + marker idempotency
+ backgroundDispatch negotiation). CONTEXT.md glossary + matrix + how-to updated;
changeset (Added).

c6ce110efa feat(#2092): migrate Qwen Code onto EoS imperative adapter + native subagents + SubagentStart (ADR-1239)
Fold all runtime==='qwen'/isQwen logic branches (skill-priority frontmatter,
branding/path rewrites, legacy commands/gsd cleanup, hyphen-namespace
normalization, RUNTIME_CONTENT_DISPATCH, hooks-surface label) into
descriptor-driven runtime.hostBehaviors on capabilities/qwen/capability.json,
read via _hostBehaviors(). Shared claude/qwen/hermes legacy-migration branches
in install-engine.cts folded to descriptor flags (claude+hermes descriptors
updated; FALLBACK_HOST_BEHAVIORS.claude floored). Byte-identical golden parity
for qwen/hermes/claude(global+local).

UPGRADE 1: native .qwen/agents/*.md subagent projection — new agents
artifact-layout kind + convertClaudeAgentToQwenAgent converter (name +
description + tools YAML block list; color/model dropped). qwen routed onto
the descriptor-driven agents path (_DESCRIPTOR_AGENTS_RUNTIMES).
UPGRADE 2: SubagentStart hook wired into extendedHookEvents + the
descriptor-gated hook-writer loop (activates only for qwen).

Tests: qwen-imperative-reference (adapter/axes/fail-closed/hostBehaviors +
no runtime==='qwen' source-grep across 4 files) + qwen-upgrades (agents file
validity + SubagentStart mirrors SubagentStop, descriptor-gated). Docs matrix
+ how-to updated; changeset added.

45f3a2a5f9 fix(#2089): wire adapter into install path + address all review findings
MEDIUM fixes (code review):
- Wire resolveManagedHookEvents + resolveHookScripts + buildHookBusEntries
  from imperative-hook-bus.cts into writeCursorHooksJson — the install path
  is now truly descriptor-driven (reads hostBehaviors.managedHookEvents),
  not a hardcoded constant that happens to match the descriptor. bin/install.js
  passes the descriptor list via opts.managedHookEvents.
- buildHookBusEntries is now consumed (was dead code); entry-building is no
  longer duplicated inline.
- Remove try/finally from cursor-hook-bus-upgrade.test.cjs test bodies
  (violated CONTRIBUTING.md L342; redundant with t.after cleanup).

LOW fixes:
- Remove dead require('fs')/require('path') from gsd-cursor-pre-tool.js
- Fix resolveManagedHookEvents docstring (all-invalid fallback behavior)
- Add src/runtime-hooks-surface.cts to the AC2 source-guard file list

Security review: no CRITICAL/HIGH/MEDIUM findings (3 LOW are pre-existing
#777 baseline patterns, not regressions).

8f2ebbe9bf feat(#1928): remove sunset Gemini CLI runtime, redirect to Antigravity (#1996)
* feat(#1928): remove sunset gemini cli runtime, redirect to antigravity

Google sunset Gemini CLI on 2026-06-18; Antigravity CLI is its official successor (already a first-class GSD runtime). Remove the gemini runtime from the enum (16->15), aliases, labels, config-home fragment, install path, converters (convertClaudeToGemini{Markdown,Toml,Agent}, convertSlashCommandsToGeminiMentions), capability descriptor, gemini-extension.json, RULESET.GEMINI.*, and the interactive menu (renumbered, no gap).

--gemini now prints an explicit deprecation notice citing the 2026-06-18 sunset and redirects to --antigravity (no silent alias, per the issue's Hyrum's-Law rejection). Antigravity is preserved throughout: its GEMINI.md contextFileName, .gemini/antigravity config home, the shared convertGeminiToolName/claudeToGeminiTools tool vocabulary, and the 'gemini' hookEvents dialect it declares. GEMINI.md retargeted as Antigravity's context file.

871621c3c8 feat(#1740): require-fs-op-fallback production AST rule + Windows transient-lock retry (Phase 6) (#1742)
* feat(#1740): require-fs-op-fallback production AST rule + Windows transient-lock retry (Phase 6)

ADR-1703 Phase 6 of the cross-platform portability epic (#1702). Adds the
second production-code portability AST rule + the ADR-mandated glob expansion
to bin/install.js and scripts/build-hooks.js.

- eslint-rules/require-fs-op-fallback.cjs: flags an unguarded fs.rename /
  fs.renameSync (the atomic-publish primitive named first in
  DEFECT.WINDOWS-FS-OPS.symptom) that is NOT inside a try/catch whose handler
  references a transient errno ('EPERM'/'EBUSY'/'EACCES' or a *RETRY_ERRNOS
  set) AND NOT behind a Windows platform guard. A catch that silently swallows
  or cleans-up-and-rethrows without an errno check does NOT satisfy the
  defect's 'never silently swallow' clause. copyFile/unlink are deliberately
  not flagged (they are the fallback primitives per the defect's own
  fix-forward). Scope narrowed to rename per Phase 5's precision discipline;
  documented on #1740.

- src/shell-command-projection.cts: export retryRenameSync(from, to) — the
  drop-in bounded-retry helper over the existing atomicRenameWithRetry.

- 27 bare fs.renameSync sites across 11 modules routed through retryRenameSync
  (capability-lifecycle/lock/source, installer-migrations, milestone, phase,
  planning-workspace, roadmap-upgrade, runtime-hooks-surface, state,
  workstream). Idempotent on POSIX; resilient to AV/indexer transient locks
  on Windows.

- eslint.config.mjs: register rule at error on src/**/*.cts; new focused
  portability-rules block covering bin/install.js + scripts/build-hooks.js
  (ADR-1703 L124-126 glob expansion — both files are compliant: zero
  rename violations).

- tests: 15-case RuleTester suite; portability-rule-disable-ban extended
  (PROTECTED_RULES + scans bin/install.js/build-hooks.js with shebang
  handling); ci-test-scope portability-lint selection rule.

- CONTEXT.md DEFECT.WINDOWS-FS-OPS predicate rewritten to point at the rule;
  docs/contributing/cross-platform-portability-rules.md reference + how-to.

Closes #1740

* chore(#1740): backfill changeset pr:1742

* fix(#1740): tighten require-fs-op-fallback precision (codex review HIGH-1/HIGH-2)

Addresses two false-negative findings from the codex (gpt-5.5/high)
adversarial review of PR #1742:

HIGH-1 — a catch that REFERENCES a transient errno but only rethrows (no
retry/fallback) was marked compliant. The DEFECT.WINDOWS-FS-OPS fix-forward
requires retry, not just recognition. Fix: catchHandlerHasRetrySignal now
requires a loop `continue` backedge OR a `return <call>` delegation; a bare
rethrow is flagged. The misleading `/* retry logic */` valid test is replaced
with a real retry loop, and the rethrow-only shape is added as invalid.

HIGH-2 — the nested-try ancestor walk treated an OUTER errno-catch as
protecting the rename even when an INNER catch intercepted/swallowed the error
(the outer catch is unreachable). Fix: isInsideTransientErrnoTryCatch now stops
at the NEAREST enclosing TryStatement WITH A CATCH HANDLER whose block contains
the rename (try-finally is skipped — it doesn't catch); outer catches are no
longer consulted. The unsound nested-try valid test is converted to invalid,
and a try-finally-skipped valid case is added.

Verified: 17 RuleTester cases pass; zero new production violations (the 27
fixed sites use retryRenameSync; the real retry loops — atomicRenameWithRetry,
capability-ledger/consent, build-hooks — remain compliant via continue/errno);
lint:ci green; disable-ban + vocab-drift green.

9d12725e4e fix(#1619): normalize pruned mise node execPath to the stable shim in normalizeNodePath (#1621)
* fix(#1619): normalize pruned mise node execPath to the stable shim

resolveNodeRunner() bakes process.execPath into managed .js hook commands.
Node realpaths execPath, so under mise it resolves to a concrete
<data>/installs/node/<ver>/bin/node that mise prunes on `mise up`, after
which every managed hook 404s — the same ephemeral-path failure #977 fixed
for fnm and #3181 for Homebrew. normalizeNodePath now rewrites a mise
versioned install path to the stable sibling shim <data>/shims/node when it
exists (deriving <data> from execPath so a custom MISE_DATA_DIR works),
falling back to the raw execPath otherwise. Tests folded into
install.test.cjs per the regression test-name lint.

c03f3cc6af fix(#1348): canonicalize Codex hooks.json writes to the nested { hooks } shape (#1363)
* fix(#1348): canonicalize Codex hooks.json writes to the nested { hooks } shape

reconcileCodexHooksJsonEvent preserved whatever shape it read, so on an empty,
absent, or legacy top-level hooks.json it wrote top-level event keys
(`{ "SessionStart": [...] }`) that current Codex (deny_unknown_fields) rejects,
instead of the canonical `{ "hooks": { "SessionStart": [...] } }`.

- Lift any top-level event arrays (legacy, empty, or mixed nested+top-level)
  into the nested `hooks` table, merging same-named events so no user/legacy
  entry is dropped and no stray top-level event key survives. Mirrors
  reconcileCursorHooksJson.
- Collapse an empty hook table back to `{}` so removal on an absent file does
  not write a spurious `{ "hooks": {} }`.

94872662e9 feat(#1082): complete phase 5 — descriptor-drive all install surfaces + materialize the InstallPlan — ADR-857/1016/58 (#1080)
* feat(#1077): phase 5f-2 — drive the hookEvents dialect (PostToolUse/AfterTool) from the descriptor

postToolEvent (bin/install.js) and preToolEvent (applySettingsJsonHooks in
runtime-hooks-surface.cts) now select the event-name dialect from
registry.runtimes[id].runtime.hookEvents instead of the hardcoded
(runtime === 'gemini' || runtime === 'antigravity') check: hookEvents === 'gemini'
→ AfterTool/BeforeTool; else → PostToolUse/PreToolUse. hookEvents threaded into the
applySettingsJsonHooks opts bag. Equivalence-preserving (Codex-verified): hookEvents
'gemini' is exactly {gemini, antigravity}, 'claude' the rest; undefined → claude
dialect (matches the old else).

The per-event SET guards (isQwen||claude → SubagentStop/Stop/PreCompact;
runtime==='claude' → FileChanged; isGemini → Gemini agent-events) stay HARDCODED —
hookEvents (2-value) is too coarse to drive them (the event set differs within
hookEvents='claude'); per-event-set drive tracked in #1076.

Registry-parity test (enh-1077): asserts BOTH post-tool (AfterTool/PostToolUse) AND
pre-tool (BeforeTool/PreToolUse) dialects are a pure function of hookEvents, for
gemini/antigravity/claude/augment — non-vacuous (catches a broken hookEvents thread).

Closes #1077

* test(#1077): build hooks/dist in before() so dialect-drive test passes in scoped CI

hooks/dist is gitignored and absent in scoped/windows CI jobs that do not
pre-run build:hooks. Without it, install() finds no hook files and all
AfterTool/BeforeTool/PostToolUse/PreToolUse event arrays come back empty,
failing every hook-presence assertion. Added an idempotent ensureHooksDist()
called in a top-level before() — mirrors the pattern from
bug-376-claude-js-hook-gsd-rewriter.test.cjs.

* feat(#1055): add installSurface/writesSharedSettings/permissionWriter/extendedHookEvents to runtime descriptors

Purely additive: four new fields on all 16 runtime capability.json descriptors,
validator extended with three new closed-vocab sets, registry regenerated.
Test fixtures (VALID_RUNTIME_CAP and makeRuntimeCap) updated to include the new
required fields so all 255 capability-registry tests continue to pass.

* feat(#1076): drive per-event hook guards from extendedHookEvents descriptor

Replace hardcoded runtime-name checks (isQwen||runtime==='claude',
runtime==='claude', isGemini) in applySettingsJsonHooks with a single
descriptor-driven extendedEvents array derived from the new opts field.
Remove isQwen and isGemini derivations (no remaining uses after the three
guard blocks are migrated). Wire extendedHookEvents from the capability
registry in bin/install.js call site. Add behavioral regression test
(enh-1076-extended-hook-events-drive.test.cjs) confirming the drive is
purely descriptor-based and runtime-name-agnostic.

* feat(#1055): drive resolveRuntimeConfigIntent from the runtime descriptor; retire hand-kept REGISTRY

- Rewrites src/runtime-config-adapter-registry.cts to require capability-registry.cjs
  and read installSurface / writesSharedSettings / permissionWriter from
  runtimes[id].runtime; deletes the hand-kept REGISTRY const (ADR-857 phase 5g drive 2).
- ALLOWED_CONFIG_RUNTIMES is now derived from descriptor entries that have installSurface.
- Fixes the configFormat parity gate in scripts/gen-capability-registry.cjs to read
  installSurface directly from capMap descriptor bodies, breaking the require cycle
  (adapter now requires the generated registry; gen-script must not require the adapter).
- Adds golden-master test tests/enh-1055-config-intent-descriptor-drive.test.cjs (41 tests)
  pinning all 16 runtimes' return shapes and the TypeError-on-unknown contract.
- Updates scripts/lint-test-file-count.allowlist.json (config module, +1 file).

* feat(#1076): make hooksSurface descriptor load-bearing for the settings-json hook-skip

- Adds hooksSurface?: string to ApplySettingsJsonHooksOpts and destructuring in
  applySettingsJsonHooks (src/runtime-hooks-surface.cts).
- Replaces the hardcoded !isOpencode && !isKilo hook-skip guard with
  hooksSurface !== 'none'; removes the now-unused isOpencode/isKilo derivations
  (ADR-857 phase 5g drive 3).
- Passes hooksSurface from the runtime descriptor at the applySettingsJsonHooks
  call site in bin/install.js using the established
  _capabilityRegistry?.runtimes?.[runtime]?.runtime?.hooksSurface idiom.
- Extends tests/enh-1076-extended-hook-events-drive.test.cjs with two new suites
  proving: (a) hooksSurface:'none' writes no hooks regardless of runtime name;
  (b) hooksSurface:'settings-json' writes hooks even for 'opencode' (previously
  hardcoded to skip).

* docs: record installSurface/writesSharedSettings/permissionWriter/extendedHookEvents descriptor axes in ADR-1016

Add Decision 7a documenting the four axes added in the 5f-completion pass,
update axis counts from "six" to "twelve", note 5f-completion drives as done
in Decision 8's ladder, update Out of scope to reflect #1055/#1076 are done
and 5g (InstallPlan capstone) remains the only open phase.

* fix(#1055): parity gate must fire on configFormat↔installSurface mismatch (read installSurface at the descriptor level)

The test fixture makeRuntimeCapMap did not include installSurface in the runtime object,
so the gate's typeof r.installSurface !== 'string' guard always skipped the entry and never threw.
Added installSurface as an optional third parameter to makeRuntimeCapMap and passed the correct
installSurface values ('settings-json' for claude, 'codex-toml' for codex) to the two THROWS tests.
The gate implementation already reads r.installSurface correctly from the descriptor level.

* feat(#1076): add installSurface↔hooksSurface + extendedHookEvents↔hookEvents consistency gates with rejection tests

GATE A: INSTALL_SURFACE_TO_ALLOWED_HOOKS_SURFACES map in validateRuntimeBody enforces that a
runtime's hooksSurface is valid for its installSurface (e.g. profile-marker-only only allows none,
codex-toml only allows codex-hooks-json). Derived from the 16 real runtime descriptors.

GATE B: validateRuntimeBody checks that if extendedHookEvents contains Gemini agent-events
(BeforeAgent/AfterAgent/BeforeModel), hookEvents must be 'gemini'; if it contains Claude-family
events (SubagentStop/Stop/PreCompact/FileChanged), hookEvents must be 'claude'.

Added 10 rejection tests in suite 27 covering each gate + each new field validator.
All 16 real runtimes satisfy both gates (verified before coding).
Exports: INSTALL_SURFACE_TO_ALLOWED_HOOKS_SURFACES, VALID_INSTALL_SURFACES,
VALID_EXTENDED_HOOK_EVENTS, VALID_PERMISSION_WRITERS, validateRuntimeBody.

* test(#1076): strengthen hooksSurface-drive assertions; defensive hooksSurface fallback; drop vacuous dup

1. bin/install.js: add explicit literal fallback for hooksSurface when the committed
   capability registry fails to load (opencode/kilo → 'none', all others → 'settings-json').
   The descriptor is always the source of truth in normal operation.

2. enh-1076 Suite 7: change SessionStart assertion from key-presence (hasOwnProperty)
   to at least-one-command (hasHooksFor), so the test fails if hooks are initialized-but-empty.
   ensureHooksDist() in before() guarantees hook files exist.

3. enh-1055 Test 2: remove vacuous duplicate suite that re-asserted intent.runtime === row.runtime
   already fully covered by Test 1's deepStrictEqual over all four fields.

4. capability-registry.test.cjs: fix stale comments in the grok-skip test that claimed the
   parity gate uses the adapter registry; gate reads purely from the descriptor (installSurface
   absent → typeof r.installSurface !== 'string' → soft-skip).

* feat(#1082): materialize the InstallPlan — collect install-level descriptor axes into resolveInstallPlan; route install()/finishInstall() through it (ADR-58/5g)

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs: record 5g InstallPlan materialization (ADR-58 Accepted, ADR-1016 phase-5 complete)

ADR-1016 Decision 8 step 7 updated to DONE: resolveInstallPlan(runtime) in
runtime-config-adapter-registry collects install-level descriptor axes into
the typed InstallPlan consumed by install()/finishInstall(). Out-of-scope
section updated: 5g capstone is complete, phase 5 fully materialized.
ADR-1016 line ~20 updated: InstallPlan IS now materialized (both halves).
ADR-58 Implementation note added (2026-06-11): realized in
runtime-config-adapter-registry (co-located with adapter-selection).
CONTEXT.md Runtime Config Adapter Registry entry extended to document
resolveInstallPlan and both-halves realization.

f11462e58e refactor(#1067): phase 5f-1b — extract the settings-json hook block (applySettingsJsonHooks) — ADR-857/1016 (#1075)
* refactor(#1067): promote referencesHook to runtime-hooks-surface module scope

referencesHook was declared as a local function inside install() but also
called in finishInstall() (module scope), meaning JS hoisting was the only
thing making it work from finishInstall. Move it to src/runtime-hooks-surface.cts,
export it, and have both call sites in install.js use the module's copy.

This is the prerequisite for COMMIT 2 (applySettingsJsonHooks extraction)
per ADR-857 phase 5f-1b.

* refactor(#1067): extract applySettingsJsonHooks to runtime-hooks-surface module

ADR-857 phase 5f-1b: move the ~457-line settings.json hook-registration block
from install() into applySettingsJsonHooks(settings, opts) in
src/runtime-hooks-surface.cts. install() replaces the block with a single call.

Behavior-preserving: all runtime=== guards, isGemini/isQwen/isOpencode/isKilo
derivations, postToolEvent/preToolEvent dialect branches, idempotency checks,
fs.existsSync guards, and console.log/warn messages are verbatim.

Opts bag: 13 fields — runtime, isGlobal, targetDir, postToolEvent,
updateCheckCommand, contextMonitorCommand, promptGuardCommand, readGuardCommand,
readInjectionScannerCommand, configReloadCommand, hookOpts, localCmd,
localShellCmd. preToolEvent computed inside (from runtime). workflowGuardCommand
/ worktreePathGuardCommand / validateCommitCommand / graphifyUpdateCommand /
sessionStateCommand / phaseBoundaryCommand / contextMonitorFile also computed
inside. settings.hooks-only mutations confirmed.

5 source-scan tests updated to read runtime-hooks-surface.cts alongside
install.js (concatenated), so structural regression guards remain valid at
their new canonical location.

install.js: 12700 → 12254 lines (−446).

58bfae9d6a refactor(#1059): phase 5f-1 — extract standalone hook-surface writers into a module — ADR-857/1016 (#1064)
* refactor(#1059): phase 5f-1 — extract standalone hook-surface writers into a module

Extract the structurally-isolated hook-surface writer functions (cline/cursor/
copilot/codex-hooks-json + buildHookCommand + atomicWriteFileSync + node/bash runner
resolvers) out of bin/install.js into a new src/runtime-hooks-surface.cts module
(-693 LOC from install.js). Behavior-preserving: install.js requires + re-exports
the moved functions (module.exports surface preserved); no descriptor reads, no
behavior change. Prerequisite for the descriptor-drive (5f-2), mirroring ADR-3660's
artifactLayout extract→drive split.

Review caught + fixed 3 coupling issues: (HIGH) the module's atomicWriteFileSync
dropped the shared __atomicWrittenTmps temp-tracking → now ONE shared set (module
owns it, install.js aliases it, both cleanups read it); (drift) buildHookCommand
called resolveNodeRunner(opts) vs the original resolveNodeRunner() → reverted; two
source-grep tests (workflow-guard, sh-hook-paths) that scanned install.js for the
moved functions → made behavioral/non-vacuous; duplicate runner resolvers consolidated.

Settings-json hook block (~648 LOC) deferred to 5f-1b; descriptor-drive to 5f-2.
New-module checklist done. ~62 hook test files green; gsd-test 17592/0.

Closes #1059

* chore(#1059): reconcile CLI Modules count after merging next (uat-predicate)

Merging current next (which added uat-predicate.cjs via #247) alongside this
branch's runtime-hooks-surface.cjs put the filesystem at 107 bin/lib modules, but
both sides had independently bumped the INVENTORY headline 105→106 so the merge
under-counted. Set "CLI Modules (107 shipped)" + regenerate INVENTORY-MANIFEST.json.
Both module rows already present. Fixes inventory-counts.test.cjs (the only CI red).
