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.

* 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
generated from it), INVENTORY rows for the three new hooks/lib files, and an
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

The staging fix means a Cursor install now correctly carries the two
transitive lib files it was silently missing. Additive only — no path was
removed. The golden diff is the evidence the packaging defect was real.

* 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.

03b7125293 enhance(#3909): a probe that could not run no longer asserts a verdict (#3944)
* test(#3909): failing-first suite for the fabricated probe fallbacks

Binds the four fabrication sites found by executing the surfaces (ADR-3889
failure class (c)), each with a positive control so an over-firing fix goes red:

- the blocking api-coverage.verify-pre gate certifying "no external-API
  integration" from a zero-byte phase scope
- the assumption-delta query route scanning an unresolvable phase section as
  the empty string and reporting it as an examined negative
- both capability fragments' probe fallbacks, which append a fabricated
  verdict rather than replacing, and fire on the legitimate exit-1 negative

Verification runs on the remote runner.

Refs #3909

* enhance(#3909): a probe that could not run no longer asserts a verdict

ADR-3889 Phase 5. Four sites turned a failed or unexamined probe into a
confident negative; each now reports what it could not establish.

- check api-coverage.verify-pre: a phase with no plan body and no roadmap
  section ran detection over zero bytes and PASSED the blocking seal gate,
  certifying "no external-API integration" from input it never read. It now
  holds with scope_unavailable. The discriminator is bytes examined, never
  signals found, so a phase whose plans are real and simply carry no API
  vocabulary passes exactly as before.
- query assumption-delta scan: an unresolvable phase section was scanned as
  the empty string and reported as an examined negative. It now returns
  {skipped, reason: phase_unresolved}, still at exit 0 — an ADR-2980 degraded
  result in the payload, leaving the gsd-tools exit projection to P8.
- both capability fragments: `|| echo '{"detected":false}'` appended rather
  than replaced, and fired on the legitimate exit-1 negative, so a correct
  answer and an honest skip both arrived as two concatenated objects. They now
  keep the probe's own payload and manufacture only an explicit
  probe_unavailable skip when the probe produced nothing at all.

Every registered outcome is more restrictive on a blocking gate, so this can
turn a false green red and never a red green.

Docs: FEATURES 156, CONFIGURATION (both keys), references/api-coverage.md
seal-time outcome table, and a new how-to for the reason-code vocabulary.

* test(#3909): correct the stale unknown-phase assertion

`unknown phase → detected:false, no throw (graceful)` scanned phase 999
against a two-phase roadmap and asserted `detected === false`. That pinned
the fabrication as intended behavior: the phase does not exist, so the
detector was handed the empty string and its "no core assumption changed"
answer described nothing that was ever read.

It now asserts the skipped-with-reason shape. The graceful-degradation
contract the test was actually protecting — the query succeeds and does not
throw on an unknown phase — is unchanged.

Found by code review, not by the author.

Refs #3909

* docs(#3909): author the FEATURES entry in its generator source

`docs/FEATURES.md` is generated by `scripts/gen-features.cjs` from the
per-feature fragments in `docs/features/`. The API-coverage entry was edited
in the generated file, so the next regeneration silently dropped it.

The text now lives in `docs/features/api-coverage-gate.md` and
`docs/FEATURES.md` is regenerated from it, leaving the shipped file
byte-identical and its content actually derivable.

Caught by `lint:generated-sync`.

Refs #3909

* test(#3909): bind the skip to "not found", and pin the discriminator

The first verification run went red on one case, and the case was wrong
rather than the code.

`getRoadmapPhaseWithFallback` returns `null` for an unknown phase and for a
missing ROADMAP.md, but for a section whose body is whitespace-only it returns
the heading line alone — which is not empty. So a body-less section WAS found,
and reporting `detected:false` over its heading is a real negative, not a
fabrication. The test had assumed the resolver yielded `''` there.

Correcting the test rather than the resolver keeps `skipped` bound to the
distinction the issue asks for — found versus not found — and avoids diverging
`assumption-delta scan` from `roadmap.get-phase`, which the fragment documents
as sharing one resolver.

Also adds the seeded property the test matrix had promised: for any plan body,
the scope read back is whitespace-only exactly when the body was. That pins the
gate's discriminator to bytes examined, so it cannot quietly become "no signals
found", across unicode whitespace and CRLF.

`docs/INVENTORY.md` picks up the reference doc's new seal-time outcome table —
surfaced by the co-change gate, not by a lint failure.

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

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

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

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

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

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

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

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

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

39673ae9ff fix(#3738): antigravity global skills/agents install to ~/.gemini/config (#3921)
* test(#3738): antigravity global skills/agents must resolve under ~/.gemini/config

Regression tests (RED first): --skills-root and gsd-tools query surfaces,
install-plan dest dirs, and converter skills-path rewrite.

* fix(#3738): antigravity global skills/agents install to ~/.gemini/config

Antigravity's machine-local discovery scans ~/.gemini/config/{skills,agents};
the configHome (~/.gemini/antigravity) is deprecated for artifacts. Declare the
ADR-1239 skills/agents 'home' override on the antigravity global layout — the
same mechanism codex uses (.agents) — and divert ~/.claude/skills/ references
in converted global content to ~/.gemini/config/skills/. configHome, settings,
probe/migration semantics, and the local .agents layout are unchanged.

* fix(#3738): retire deprecated configHome artifacts via installer migration 010

Next install converges an existing antigravity install: manifest-managed
skills/gsd-*/ and agents/gsd-*.md under the configHome (a location AGY does
not scan) are removed — modified files backed up first, unmanifested and
non-gsd entries preserved — and now-empty containers retired. Global scope
only; the local .agents surface is live. Docs + inventory updated.

* fix(#3738): converter sync in bin/install.js, harness emit-root coverage, migration baseline

- bin/install.js converter gains the same ~/.claude/skills → ~/.gemini/config/
  rewrite as src (ADR-1508 dual copy must stay in sync).
- Parity-manifest walk covers home-override emit roots (extraEmitRootsFor) so
  antigravity's emitted skills/agents stay differential-visible at their new
  install root; install-tree fixture regen confirms an unchanged key set.
- skills-from-commands rule declares the antigravity converter as a
  runtime-scoped transform; one ack fragment covers the identity-classed
  workflow whose antigravity copy embeds the old skills path.
- Migration 010 checksum baseline + home-override set doc updated; existing
  tests updated to the #3738 contract (global dest, golden parity via layout
  dest, integration expectations).

* fix(#3738): tolerate an absent extra emit root on baseline-side measurement

The base tree's installer predates the home override, so <HOME>/.gemini/config
does not exist there; walk() threw ENOENT and the in-job baseline build failed.
An absent extra root is the legitimate pre-override shape — skip it.

* fix(#3738): review findings — manifest agents root, bare skills-path rewrite, guard comment

- writeManifest resolves the agents-kind home override (_kindDestDirSafe), so
  the manifest records agents at their actual install root and drift detection
  keeps working (isolated review finding 1, major).
- Converter bare forms ~/.claude/skills and $HOME/.claude/skills (no trailing
  slash) divert to ~/.gemini/config/skills instead of falling through to the
  retired configHome path (finding 2).
- real-home-guard comment updated: antigravity's global agents kind is the
  first agents-kind home override (finding 3, doc-only).
- Regression tests for both behavioral findings.

* chore(#3738): changeset fragment (pr number backfilled after PR creation)

* chore(#3738): backfill changeset PR number (3921)

* fix(#3738): sandbox HOME in tests that install antigravity global artifacts

antigravity is the first home-override runtime in the golden-parity and
skills-wrapper suites (codex is not in their runtime lists), so those tests
never needed HOME sandboxing — the real-home guard now (correctly) refuses
their un-sandboxed global installs on CI, where HOME is the passwd home.

* fix(#3738): stop the K3 sequential-sandbox env leak; sandbox L2's home-override plans

K3's two back-to-back sandboxHome calls leave HOME pointing at the first
sandbox once the after-hooks restore (each call saves the env as it found
it, so the second saves the first's sandbox as 'original'). On the windows
matrix that leaked gsd-k3-qwen-* home into the L2 property, whose
antigravity/global run then (correctly) refused via the #3712 real-home
guard — antigravity is the runtime that made L2's plan escape into
os.homedir(). K3 now manages the env with a single restore; L2 sandboxes
HOME per run, mirroring L1.

* fix(#3738): L2 property's HOME sandbox must exist on disk

The #3712 guard's sandbox exemption fails closed when identify(effectiveHome)
is 'absent' — L2 never created its configDir, so on the windows matrix (tmpdir
under the real home) the antigravity/global run refused even with HOME
sandboxed. Create the per-run sandbox dir and clean it up.

ADR-3473 §8.4 says failure is a value. Three families currently encode failure as
success, and this commit pins each one RED before the fix lands.

Measured on this tree, 2026-08-26:

  gsd-tools generate-slug "test" --pick nonexistent
    -> empty stdout, exit 0                                     (#3365)

  gsd-tools audit-open --pick nonexistent_field
    -> dumps the entire human-readable audit report, exit 0

  gsd-tools generate-slug "Hello World" --raw --pick bogus
    -> prints "hello-world", another field's value, exit 0

  gsd-tools query state.planned-phase 3        (positional, no --phase)
    -> exit 0; STATE.md's "Phase: 2 of 5 (Widget Support)" is overwritten to
       "Phase: null - READY TO EXECUTE" and the frontmatter gains a corrupted
       current_phase_name                                        (#3358)

tests/pick-flag.test.cjs:27 previously asserted the #3365 defect as the contract
("returns empty string for missing field", success === true). That assertion is
replaced by the required behavior rather than deleted.

The new parseNamedArgs block calls the spec-object signature that does not exist
yet, so it fails today by construction. The 11 existing behavior-lock tests are
left untouched here; they are corrected in the implementation commit.

C1/C4 assert at the consumer's output - STATE.md's bytes - per ADR-3180
Decision 4(b). A unit assertion on the parser would have passed throughout this
defect's life.

* enhance(#3884): failure is a value — strict argv, and --pick that signals absence

Implements ADR-3473 §8.4. Absence, emptiness and failure stop being interchangeable
ways to say "I could not answer".

parseNamedArgs (src/command-arg-projection.cts)
  Takes a spec object with a REQUIRED `positionals: number | 'rest'` and returns the
  hub's Result shape instead of a bare Record. Declaring the positional arity is what
  makes #3358's call site unrepresentable rather than merely detectable: an unrecognized
  flag or a token past the declared boundary is now InvalidArgs, naming the offending
  token and listing the accepted flags. The legacy positional-array call shape throws
  a TypeError — an internal invariant violation per ADR-3473 Decision 2, so a stale
  hand-written .cjs call site fails loudly instead of destructuring undefined off a
  Result. parseNamedArgsOrExit projects a failure onto the caller's error(); it is a
  projection over the one parser, not a second parser.

  Measured before, against a STATE.md with a populated phase-2 block:
    query state.planned-phase 3        (positional, no --phase)
    -> exit 0; "Phase: 2 of 5 (Widget Support)" overwritten to
       "Phase: null - READY TO EXECUTE", frontmatter gains a corrupted
       current_phase_name
  After: exit 1, `unexpected positional argument "3"`, STATE.md byte-identical.
  The flag form is unchanged and still updates STATE.md.

--pick <field> (gsd-core/bin/gsd-tools.cjs)
  extractField returns {found,value}, and the pick block no longer shares one catch
  between "output was not JSON" and "field was absent". An absent field exits 1 with
  pick_field_absent, naming the field and the keys that do exist; non-JSON output exits 1
  with pick_output_not_json instead of dumping the command's entire output. A field that
  is PRESENT with value null, '', 0 or false still prints at exit 0 — that is an answer,
  not a failure, and it is what keeps `--pick count` printing 0 on a fresh project.

  Measured before: `audit-open --pick nonexistent_field` printed the whole human-readable
  audit report at exit 0, and `generate-slug X --raw --pick bogus` printed "hello-world" —
  a different field's value, confidently, at exit 0.

  ADR-3409 Decision 7 explicitly deferred this contract fix to #3473; this is it. The
  sub-issue's "returns 0 when the count is zero OR absent" wording is superseded by the
  ADR rule it implements: zero prints 0, absence exits non-zero. Defaulting absence to 0
  would demote "could not answer" to "the answer is zero" — the hazard
  docs/how-to/resolve-unreachable-guard-findings.md already warns against.

Guard ledger (ADR-3473 Decision 6)
  scripts/lint-unreachable-guard-drift.cjs Detector A is RETIRED. Its premise — that a
  `--pick ... || echo` arm can never fire — is now false, so the shape it forbade is the
  correct idiom and keeping it would forbid the fix. Detector B (glob-consuming cat/ls,
  a nullglob mechanism this change does not touch) is retained in full, as are the shared
  scanner, the escape-marker parser and the baseline. Net: -1 detector, 0 added. The file
  is not deleted.

Call-site audit
  45 prompt-layer --pick invocations, every one a plain X=$(...) assignment — none in an
  if test, && chain, or a pipeline whose status is consumed, and no shell block in
  workflows/commands/agents/references sets -e. Of the 13 (command, field) pairs the
  prompt layer reads, 10 are always present; the 3 sometimes-absent ones each sit behind
  a prior found/existence check. No ADR-3409-class "field the command never produces"
  remains.

* fix(#3884): escape untrusted tokens in diagnostics, and cover five unpinned rows

Two review findings, both fixed here rather than recorded as limits.

1. A newline in an untrusted token forged a second stderr line.

   Before, plain-text mode:
     $ gsd-tools query state.planned-phase $'foo\nError: forged second line'
     Error: unexpected positional argument "foo
     Error: forged second line"

   After:
     Error: unexpected positional argument "foo\nError: forged second line"

   --json-errors mode was never affected — io.error runs that payload through
   JSON.stringify. Plain-text mode writes 'Error: ' + message verbatim, and the
   three new InvalidArgs reasons plus the two new --pick diagnostics all
   interpolate a token that comes straight from argv.

   Fixed with ONE shared helper, formatDiagnosticToken (src/io.cts), applied at
   every interpolation site — not a copy per site. It is deliberately NOT
   applied inside error() itself: several callers in this tree emit intentional
   multi-line diagnostics, and escaping newlines there would mangle them.

   The available-top-level-keys list needed the same treatment for a reason the
   review did not anticipate: `frontmatter get <file>` reads an ARBITRARY user
   document and echoes that document's own keys into the diagnostic. Verified
   reachable — a frontmatter key containing a newline reaches the key list — so
   formatKeyForDiagnosticList is guarding a live path, not a hypothetical one.
   Ordinary keys still render plain and unquoted; a fix that merely dropped the
   key would also have passed a "one line" assertion, so the test pins the
   escaped key's presence too.

2. Five behavior-table rows were implemented but nothing pinned them:
   B7  a dotted path that dies partway
   B9  bracket syntax on a non-array
   B10 a negative array index, in and out of range
   B14 a JSON root that is not an object
   B17 an @file: payload over 50KB

   B17 is the load-bearing one. output() writes @file:<path> instead of inline
   JSON past 50000 characters, and --pick resolves that BEFORE parsing; with no
   test, a future reordering of those two steps turns every large result into a
   false pick_output_not_json. The fixture seeds 1200 phase directories and
   measures the payload at 62474 characters, asserting the spill actually
   happened rather than assuming it.

* fix(#3884): correct the strict-argv surface against a full verification run

The first full run came back with 90 failures across 12 files, none in the new
tests. They were the argv surface telling me what it actually is. Ten root
causes; each classified before anything was changed.

I over-implemented, and that is reverted.

  ADR-3473 §8.4 says parseNamedArgs rejects "unrecognized and positional
  tokens". It says nothing about a value flag whose value is missing. Making
  that an error was my design decision, not the rule, and it broke a
  deliberately recorded contract: `--prd` with no value resolving to null
  (tests/init.test.cjs emptyPrdValueIsFalsyAndTreatedAsAbsent, row B5;
  tests/section-manifest-init-facts.test.cjs "flag-shaped value"). The
  "requires a value" branch is deleted outright rather than kept behind an
  option — an unused strictness mode is speculative generality. Unknown-flag
  and unexpected-positional rejection, which is what §8.4 actually mandates,
  is unchanged.

--wave needed a third flag kind the original design did not anticipate.

  `--wave N` is documented (commands/gsd/execute-phase.md:4,48) and the
  shipped workflow reconstructs and passes it (execute-phase.md:84), while
  #2932 records token-PRESENCE semantics: the CLI cares only that the flag
  appeared, and the value belongs to the workflow layer. That is neither a
  boolean flag nor a value flag, so `optionalValueFlags` now exists —
  presence-only in `data`, and the validation cursor consumes a following
  non-flag token so it is not reported as a stray positional. Every other
  declared boolean flag was checked against every argument-hint and prose
  usage in commands/, workflows/, agents/ and docs/; `--wave` is the only one
  of this shape.

Five tests were pinning forms that never worked.

  tests/adr857-core-without-capabilities.test.cjs passed
  `init plan-phase --phase 01-stub`, but the documented form is positional
  (docs/CLI-TOOLS.md:776) and the handler reads args[2] — which for that form
  is the literal string "--phase". Measured on the pre-fix build against a
  real .planning/phases/01-stub/ directory:

    init plan-phase 01-stub          -> phase_found=true
    init plan-phase --phase 01-stub  -> phase_found=false

  The test asserted only exit 0 and key presence, so it had been green while
  proving nothing about phase resolution. Corrected to the documented form and
  strengthened to assert phase_found === true. Same class in state.test.cjs
  (`--plan-count`, a flag that does not exist; the real one is `--plans`),
  milestone-archive.test.cjs (`init new-milestone --json`, silently ignored),
  and concurrency-safety.test.cjs (a bare positional field name whose
  OR-assertion passed because a whole-document dump happens to contain the
  substring it looked for).

Six handlers had no argv validation at all — the same #3358 shape this phase
exists to close, found while fixing the rest: init verify-work / phase-op /
review / todos / remove-workspace read args[2] with nothing checking the rest,
and validate health read --repair/--backfill through a bare args.includes()
scan that bypassed the parser entirely. All now go through the seam, so the
flag has one owner.

tests/init-debug.test.cjs rows C4/C5 asserted that an unrecognized flag must
NOT fail. That is the behavior §8.4 removes, and Decision 8 says a caller's
local expectation does not override §8, so they are inverted and renamed —
a test still called "ignores an unrecognized flag" while asserting rejection
would be its own defect. Row C6's point is its PWNED canary; that assertion is
kept verbatim and only its exit-status expectation changed, because the
hostile token is now rejected rather than absorbed.

The blast-radius estimate in 40-design.md is corrected rather than quietly
left wrong. get_impact reported MEDIUM / 8 symbols upstream, and that was
accurate for what the graph can see — parseNamedArgs's callers. It cannot see
that those callers' handlers accept argv shapes wider than the code reading
args[2] suggests, which is where the real surface was.

* fix(#3884): withdraw the validate-health tightening, finish the A2/A3 revert

Second full run: 46 failures, down from 90. Four causes, two of them mine.

Reverted `validate health` entirely — it was scope creep, and it broke a real flag.

  ~30 of the 46 read `unknown flag "--json"; accepted: --repair, --backfill`.
  The previous commit routed `validate health` through the parser on the
  reasoning that a flag should have one owner. That was wrong twice over:
  §8.4 names parseNamedArgs and count queries, and `validate health` was never
  a parseNamedArgs call site — it read its flags, just not through the parser,
  so it had no silent-drop defect to fix. Tightening it omitted `--json`, which
  the health-diagnostic suites use heavily. The handler is now byte-for-behaviour
  back to its pre-branch form. `validate context` stays converted: it genuinely
  was a call site, and its `--json` is now declared rather than read by a second
  `args.includes` scan.

  The five handlers that had NO validation at all — init verify-work / phase-op /
  review / todos / remove-workspace — stay fixed. Those read args[2] with nothing
  checking the rest, which is the #3358 shape this phase owns.

Finished the A2/A3 revert. Three tests still encoded the deleted
"a value flag with a missing value is an error" rule, including one added by the
previous commit for that rule. All three now assert the reverted null contract,
and the ones whose titles said "rejected" are renamed — a test named for a
contract it no longer asserts is its own defect.

`--wave=` and `--wave --weird` are correctly rejected. Neither is documented in
commands/gsd/execute-phase.md, gsd-core/workflows/execute-phase.md or docs/, and
neither is emitted by the shipped prompt layer, so both are unrecognized tokens
that §8.4 mandates rejecting. `doesNotConsumeFollowingFlagAsWaveValue` keeps the
property it exists for — asserted directly now, at the parser, that `--wave` does
not swallow a following flag as its value — and only its exit-status expectation
changed.

A contradiction inside this branch, surfaced by the audit and resolved the safe way.

  Two pre-existing #3573 tests call `state begin-phase '2'` and
  `state planned-phase '2'` with a bare positional, relying on the old permissive
  parser to ignore it. This branch's own #3358 regression test requires that exact
  argv to be REJECTED. The two are mutually exclusive.

  Widening the router to accept a bare positional — mirroring complete-phase —
  would have silently re-opened #3358, and was verified to do exactly that: with
  the widened router, `query state.planned-phase 3` returned exit 0 and wrote
  current_phase_name again. It is reverted. docs/CLI-TOOLS.md:116 and
  docs/COMMANDS.md:2192 document only the `--phase N` form for both verbs, so the
  two #3573 tests move to it. Their assertions were never about the call shape —
  only that total_phases survives the resync — and both still pass.

  complete-phase is untouched: its bare positional IS documented, and it keeps the
  dynamic boundary and the negative-space note that record why.

The audit that produced this is in the PR body: for every handler whose declaration
changed, the flags it reads anywhere in its body, the flags the shipped surface
documents, and the shapes the suite passes, compared. The `--json` miss was a
pattern, not an accident — declaring a handler's flags from its parseNamedArgs call
alone misses whatever it reads elsewhere.

* feat(#3905): the exit-code registry — one number, one meaning, enforced at build

A generated registry replaces locally-invented exit codes. Every entry records code, name, meaning, owning module and the decision that authorized it. The generator refuses to build a table where two entries claim one code, two claim one name, a code falls in a range Node or the shell reserves, 2 is claimed by anything but the hook adapter, or an allocation carries no justification. exitCodeFor is pure and total: it throws rather than returning undefined, including for prototype-chain names.

Inert by design — nothing emits a registered code until #3906. Every registered code is non-zero, asserted over the whole table, so a caller testing for failure behaves identically for pass and trips for everything else.

* feat(#3905): make the registry generator's failures machine-readable

Adds a --json mode carrying {ok, reason, context, detail}, where context is a typed payload naming the specifics the prose embedded - which code collided and under which names, which band rejected a code, which field was missing. The tests now assert on that structure instead of regex-matching the generator's stderr, which CONTRIBUTING prohibits, and the CONTEXT.md glossary gains the entry the issue's scope requires.

* test(#3905): refresh the install-tree fixtures for the new declaration

The registry declaration ships in the install tree, so all 19 golden fixtures needed regenerating. Caught by the remote matrix, not by lint:ci - the install-tree goldens are verified by a test rather than a lint, so a newly shipped file clears every local gate and fails only under the suite.

6b7df61938 enhance(#3881): one YAML parser — vendored js-yaml replaces the hand-rolled dialect (#3888)
* docs(#3881): answer §8.1's open question and correct three wrong premises

ADR-3473 §8.1 carries a blocking open question with a forcing function: it must
be answered before any implementation PR for the rule opens. Answered here as (a),
a string-coercing adapter, with the measurement that settles it.

The sequencing note bet that §8.8's schema would make (b) tractable. Measured
against merged reality it does not: only 33 of extractFrontmatter's 78 non-test
call sites read STATE.md, and two of the five compensating mechanisms §8.1 lists
survive real types, leaving ~31 lines across 3 call sites as the actual prize.

Also corrects three claims verified false while answering it. §8.1's justifying
sentence names #3349 and #3360 as defects a real parser would fix; both are
already fixed on next, confirmed by executing the compiled parser rather than
reading it. The guard roster calls lint-frontmatter-scalar-broad-grep.cjs an
expected casualty of this rule, but it guards shell grep idioms in workflow bash
fences and never touches our parser. The same roster calls lint-vendored-deps.cjs
reusable as-is; it is hardcoded to re2js throughout.

The last two were caught by applying the rule this amendment records -- a factual
claim in this ADR is a hypothesis until the implementing phase executes it -- on
its first use.

Refs #3881

* docs(#3881): record that §8.1's fork is ill-posed and (a) is not implementable

An adversarial pass on the Phase 4 design established by execution that
extractFrontmatter is not a YAML parser but a line-oriented scanner whose output
is a function of raw source text. Four spellings of the same value collapse to
one js-yaml tree but produce four distinct legacy strings, one of them mangled.
No adapter over a tree can choose among outputs the tree does not distinguish,
so fork (a) -- keep a string-coercing adapter so the existing contract holds --
cannot be built. For any document with a non-scalar value, (a) collapses into
(b); about 26 percent of frontmatter-carrying documents have one.

Also records three design defects and one new attack surface, all confirmed by
execution: catching a parse failure and returning {} would delete the frontmatter
block on the next write at eight call sites that conflate empty with unparseable;
an empty value yields null where legacy yields {}, and reconstructFrontmatter
omits null-valued keys, so the shipped state template's empty progress key would
vanish; the #1882 truncation probe is parseYamlRegion itself rather than a
pre-parse heuristic, so it cannot both stay unchanged and survive that deletion;
and FAILSAFE_SCHEMA still resolves aliases, expanding seven lines to 22.8 MB.

The rule is not deferred. The measurement is the deliverable and the re-scoping
is recorded as an open question with a forcing function, per section 8's own rule.

* chore(#3881): vendor js-yaml and generalize the vendored-deps guard to a manifest

Packaging step for ADR-3473 §8.1: makes js-yaml available to gsd-core/bin/** without promoting it out of devDependencies (promoting broke every installed tree, #3496).

gsd-core/bin/lib/vendor/js-yaml.cjs is a verbatim copy of node_modules/js-yaml/dist/js-yaml.js (the self-contained UMD dist bundle, not index.js), exposing load/dump/FAILSAFE_SCHEMA/YAMLException with zero require() calls of its own.

src/vendor/js-yaml.d.cts is hand-authored, not copied, because js-yaml ships no upstream .d.ts and @types/js-yaml is not installed. It is deliberately narrow, declaring only the four symbols in use, so anchors/aliases/custom types/loadAll are unreachable from typed code -- a compile-time enforcement of ADR-3473 §8.1's refusal to expand alias resolution for security reasons. Because it has no upstream counterpart it is excluded from the byte-compare.

scripts/lint-vendored-deps.cjs is refactored from a script hardcoded to re2js into a table-driven VENDORED manifest (one row per package: upstream/vendored .cjs paths, optional .d.cts paths, twin kind upstream-verbatim vs hand-authored) so a second vendored package does not require a second hardcoded check block, per ADR-3473 §8.3 'one implementation per rule'. The four existing re2js checks (vendored .cjs vs node_modules, vendored .d.cts vs node_modules, src/vendor twin vs bin-side twin, devDependency version pin vs installed version) are preserved unchanged; verified pass/fail identical before and after the refactor, and the guard's ability to fail was re-proven with a deliberate one-byte append to both re2js.cjs and js-yaml.cjs, then restored.

docs/INVENTORY.md and docs/INVENTORY-MANIFEST.json (via gen-inventory-manifest.cjs --write, run after build:lib) register vendor/js-yaml.cjs. gsd-core/bin/lib/vendor/README.md documents both vendored packages and the two twin kinds.

Refs #3881

* feat(#3881): parse .planning frontmatter with the vendored js-yaml

ADR-3473 §8.1: extractFrontmatter's read path is no longer a hand-rolled
line scanner. parseYamlRegion, escapeDoubleQuoted, unescapeDoubleQuoted and
parseQuotedScalar are deleted (not patched); parsing now goes through the
vendored js-yaml (./vendor/js-yaml.cjs) under { schema: FAILSAFE_SCHEMA,
json: true }. Everything js-yaml does not do is layered on top, in one
place, carrying the seven design-doc consequences:

1. Empty value: a null js-yaml value is coerced to {} (matching legacy's
   own empty-value contract) so reconstructFrontmatter — which omits
   null-valued keys — still round-trips a bare `key:` line instead of
   deleting it. Verified live: progress: with no value survives
   parse -> reconstruct -> re-parse.

2. Unparseable no longer collapses to a bare {}: a new FRONTMATTER_UNPARSEABLE
   Symbol (exported), keyed exactly like the existing #3257 FULL_LINE_COMMENTS
   channel, is carried on the {} returned for malformed/refused YAML. Invisible
   to Object.keys/entries/JSON.stringify/for-in, so the 70 call sites that
   never inspect it are unaffected; wiring the 8 hasFrontmatter sites to
   consult it is a separate change, not done here.

3. Non-scalar object-list items (the four spellings of `- test: a b` that
   js-yaml collapses into one tree shape) are rendered as a canonical
   `key: value[, key2: value2]` string per item, keeping the existing
   array-of-strings value SHAPE. A full corpus differential over all 1702
   tracked markdown files found 11 residual divergences from the legacy
   parser (enumerated in the PR/report), most of them the parser now being
   MORE correct (a dropped quoted top-level key, the block-scalar/phantom-key
   defect, a dropped Unicode key).

4. The #1882 truncation probe still runs the one real parser, but derives
   its key count from js-yaml's own thrown error and mark.line when the
   whole region doesn't parse cleanly (the dominant real truncation shape:
   fence opened, well-formed keys, no closing fence). Verified against both
   the clean-parse and the exception-fallback path.

5. The #3257 comment channel now attributes each pending column-0 comment
   against js-yaml's own parsed top-level key list (matched by literal key
   text, in document order) instead of the legacy ASCII-only key regex, so
   a comment above a Unicode key attaches correctly.

6. Anchors, aliases and merge keys are refused outright (a raw-text
   pre-scan, since FAILSAFE_SCHEMA still resolves them) — corpus occurrences
   today: zero. A 7-line billion-laughs fixture is verified refused rather
   than expanded.

7. A literal U+0000 is swapped for a private-use sentinel before the parse
   and restored in every resulting string afterward, since js-yaml rejects
   NUL unconditionally under every schema.

escapeDoubleQuoted is deleted and reimplemented via js-yaml's dump()
(forced double-quoted style), with control-char hex escapes lowercased to
keep serialized output byte-stable (#1779 emitted lowercase); it keeps its
exported name and signature for its two other call sites (commands.cts,
runtime-artifact-conversion.cts), which need no change.

frontmatterDeepEqual, the comment channel, sliceTopLevelFrontmatterSegments,
regenerateFrontmatterKey's guard, noOpObjectListSetError and
parseMustHavesBlock are all unchanged — retiring them is fork (b) and is
not this phase.

Refs #3881

* fix(#3881): quote template placeholders and preserve unparseable frontmatter

SECURITY.md/UI-SPEC.md/VALIDATION.md wrote frontmatter placeholders as
bare {N}/{phase-slug}/{date}, which is valid YAML flow-mapping syntax
under the vendored js-yaml parser, not the literal placeholder text
intended. Quote them so they parse as strings.

Wire the FRONTMATTER_UNPARSEABLE Symbol (exported but unused) at the
8 call sites in state.cts/state-transition.cts that compute
hasFrontmatter via Object.keys(extractFrontmatter(...)).length > 0 and
reassemble the document without a frontmatter block when false. That
check conflated 'no frontmatter' with 'unparseable frontmatter' (both
parse to {}), so a document with a merge-conflict marker or refused
alias in its frontmatter had that block silently dropped on write.
Each site now preserves the exact raw bytes stripFrontmatter removed
when the marker is set, leaving the genuinely-empty case unchanged.

Two errors in the entry as first written: it named parseYamlRegion as part of
the read path when that function is deleted, and it recorded the eight
hasFrontmatter call sites as unwired follow-on work when they were wired in
e35ac2a2c. Also records the scope caveat that the CLI write path rebuilds the
frontmatter block independently, so the marker binds at the transform layer.

* docs(#3881): record the semantic-migration decision and the counted guard ledger

The maintainer chose the full semantic migration over splitting the rule into
its own epic or patching the scanner, so section 8.1 is answered as "the fork
was ill-posed and the migration is semantic" rather than as (a) or (b).

Also replaces the pre-implementation guess that this phase would shrink the
guard surface with the counted result: excluding vendored third-party lines the
hand-maintained surface is net +307, and frontmatter.cts grew by 68 lines
despite four functions being deleted, because the compatibility layer over
js-yaml is larger than the scanner it replaced. Section 8.1's stated benefit is
therefore not delivered as written; what improved is the kind of code
maintained, not the amount. Decision 6 requires recording that rather than
netting it away.

* fix(#3881): refuse anchors structurally and fold in review findings

ADR-3473 §8.1 review findings, addressed inline:

Finding 1 (BLOCKER): refuseAnchorsAndAliases was a raw-line regex that matched
only the bare-key spelling (key: &x). A quoted key ("a": &x), a flow mapping
({b: &x}) and a flow sequence ([&x, *x]) all define/use the SAME anchor
mechanics while never matching that line shape, so the exact expansion the
guard exists to stop went straight through unrefused (a 303-byte quoted-key
bomb expanded to ~35.8MB). Replaced with js-yaml's own `load` `listener`
callback, which reports `state.anchor` for every event belonging to an
anchored node in every spelling, and throws from inside the callback to abort
before any expansion (~1-2ms vs full expand-then-discard). A merge key with
an alias is still refused (merge always requires a previously anchored node,
so the alias itself trips the listener); a bare merge key with NO alias is no
longer separately refused, documented as intentional: FAILSAFE_SCHEMA never
resolves `!!merge`, so it carries no expansion risk. Table-driven tests added
for all four bypass spellings + merge key, plus a quoted-key-spelled
billion-laughs fixture registered in the adversarial matrix and README.

Finding 2: src/vendor/js-yaml.d.cts's docblock falsely claimed anchors/
aliases were "simply UNREACHABLE from typed code" through the twin. Corrected
to state the truth: anchor/alias resolution is document-level `load`
mechanics reachable through exactly the declared surface, and refusal is
enforced at RUNTIME (Finding 1's listener), not by the type surface.

Finding 3 (MAJOR): the null-byte sentinel (U+E000) round-trip was
non-injective — restoreNullBytesDeep rewrote every U+E000 in the parsed tree
back to NUL, including one the document author legitimately wrote, silently
corrupting it. Now refuses outright whenever the raw region already contains
U+E000 (consistent with the existing anchor/merge-key refusal path), making
the substitution provably injective. Tests added for a real NUL alone
(preserved), a pre-existing U+E000 alone (refused, not corrupted), and both
together (refused, not merged into one byte).

Finding 4 (MAJOR): scripts/lint-vendored-deps.cjs's `srcTwin` field was dead
for a hand-authored row (only read inside the upstream-verbatim branch) —
exactly how Finding 2's stale docblock drifted unnoticed. Added
checkHandAuthoredTwin: every value-level export the twin DECLARES must be an
actual own property of the vendored runtime module at require-time. Tests
added, including a sensor that a declared-but-nonexistent export IS caught.

Finding 5: the existingFm/hasFrontmatter/stripFrontmatter/fmPrefix/
unparseableFm/reassemble preamble, copy-pasted at 7 sites in
state-transition.cts plus a sixth hand-inlined copy in state.cts's
cmdStateCompletePhase, is now one exported helper
(beginFrontmatterReassembly) every site routes through, including the
hand-inlined one. Three call sites (beginPhaseCore, patchCore, updateCore)
keep a literal `body = stripFrontmatter(content)` assignment alongside the
helper call so scripts/lint-state-write-path-drift.cjs's single-hop backward
scan (which does not chase aliases) still sees the strip; stripFrontmatter is
pure/idempotent so the extra call changes nothing observable.

Finding 6: corrected the frontmatter.cts docblock's stale "wiring is a
separate change" claim (the 8 call sites are wired on this branch) and the
changeset's backlink from (#3473) to (#3881).

Finding 7: fixed the lint:ci failures blocking the gate — an
@typescript-eslint/only-throw-error violation from throwing a bare Symbol as
the anchor-detected signal (now a real Error subclass), unused-var warnings
left over from the Finding 5 refactor, a lint-test-file-count cap exceeded by
two migration-specific test files (allowlisted with justification), and the
lint-state-write-path-drift false positive from Finding 5's helper (fixed
above). tests/frontmatter-golden-parity.test.cjs:117's execFileSync already
carried an explicit timeout; no change was needed there.

Golden fixture: added a golden entry for the new
anchor-alias-bomb-quoted.md fixture ({} — matches what the legacy line
scanner would also produce, since it independently dropped every quoted
top-level key). No other corpus document diverges: real .planning/ documents
carry zero anchors/aliases/merge keys/U+E000 today.

Refs #3881

* fix(#3881): fold in second-round review findings

Finding 1 (BLOCKER): tests/frontmatter.test.cjs pinned the pre-migration
ASCII-only key regex for the Unicode fixture; updated to require the 相
key's value now that js-yaml has no such restriction. Audited the rest of
the file for other pre-migration pins (block scalars, quoted keys,
flattened values, empty values, duplicate keys, unclosed blocks, null
bytes) by execution against real fixtures; found none regressed.

Finding 2: parseYamlRegion and escapeDoubleQuoted renamed to
parseGuardedYamlRegion and escapeDoubleQuotedScalar in src/frontmatter.cts
so no function still answers to the deleted hand-rolled scanner's name
(ADR-3473 §8.1 "deleted, not patched"). escapeDoubleQuotedScalar's three
external call sites (src/commands.cts, src/runtime-artifact-conversion.cts)
updated in the same change — a mechanical rename, not an ADR-amendment
matter.

Finding 3 (BLOCKER): fixed a real crash and a silent data-loss bug found
by execution. A top-level key named constructor/__proto__/toString/
valueOf/hasOwnProperty crashed reconstructFrontmatter (bracket read
resolving an inherited Object.prototype member); a key literally named
__proto__ was silently DROPPED entirely (bracket assignment on an
ordinary {} invoked the inherited __proto__ setter instead of creating a
data property). Fixed by building every parsed Frontmatter object with
Object.create(null), and replacing an `in` check with hasOwnProperty.call
in propagateCommentChannel. Added round-trip tests for all five hostile
keys, each with its own leading comment.

Finding 4 (MAJOR): escapeDoubleQuotedScalar's docstring falsely claimed
full byte-stability across the migration. Verified by execution: BEL/NUL/
NEL/NBSP/LS/PS/BOM now emit YAML-named escapes instead of the old hex/raw-
literal forms. Proved round-trip equivalence (each escape re-parses to the
exact source codepoint) and corrected the docstring. Found and fixed a
related real defect while verifying: a lone UTF-16 surrogate was emitted
BARE (scalarNeedsDoubleQuoting didn't trigger), producing genuinely
unparseable YAML that silently collapsed to {} on re-read — extended
scalarNeedsDoubleQuoting to route surrogates through the quoted+escaped
path.

Finding 5 (MAJOR): countKeysBeforeTruncation went silent on 4 real
truncation shapes (unquoted colon, open flow collection, mis-indented
sibling key, refused anchor). Root cause: the mark-based prefix recovery
excluded the very line whose key needed counting, and a mark-less refusal
never entered the recovery branch at all. Fixed by taking the max of two
lower bounds: the longest parser-verified line-prefix, and a raw-text
count of key-shaped lines (reusing the same key-shape pattern this file
already uses for isFrontmatterShaped). Extended test-matrix row A5
table-driven over all 4 regressed shapes.

Finding 6: the design doc's claim that no test owned the #3594 adversarial
fixture corpus was false — consolidation epic #1969 had already folded it
into tests/frontmatter.test.cjs. An earlier commit on this branch
re-created a standalone duplicate under that false premise; folded its
genuinely-new coverage (fixture-ownership check, anchor-bomb fixtures,
block-scalar B1/B2 rows) into frontmatter.test.cjs and deleted the
duplicate file. Corrected the false claims in 40-design.md §3.3.1 and the
ADR's §8.1 note, including the roadmap-sibling claim (no such file exists).

Finding 7: the golden serializer sorted object keys, making it structurally
blind to the key-order-parity invariant ADR-3473 §8.1 actually claims.
Made it order-preserving and regenerated the golden fixture from a
standalone compile of the legacy (pre-#3881) parser at ddde001af; the
current parser matches it with zero undocumented divergences, confirming
key-order parity genuinely holds. Extended row A2 table-driven across 6 of
the remaining 7 transitionCore kinds (all pass) plus documented, by
execution, a newly-discovered 8th-site regression: state.cts's
cmdStateCompletePhase calls the same preservation helper but its result is
clobbered by a later unconditional resync — filed as a distinct finding
rather than fixed here (touches syncAndPreserveStateMd, outside this
change's verified scope).

Refs #3881

* fix(#3881): preserve unparseable frontmatter through the CLI write path

Characterization (executed, before/after shown): case (b), not (a). The
frontmatter FENCE survives — `state complete-phase` on a conflict-marked
STATE.md returns success and a well-formed, freshly-derived frontmatter
block, not a document with no frontmatter at all. But the block's actual
content (the merge-conflict markers, and with them any signal to a human
that the document was in conflict) is silently discarded and replaced.

Root cause was two clobber sites, not one:

1. syncStateFrontmatter (src/state.cts) re-parses the already-preserved
   `transformedContent` from readModifyWriteStateMd, finds {} + the
   FRONTMATTER_UNPARSEABLE marker, and unconditionally rebuilt a fresh
   frontmatter block from the body anyway.
2. Even after (1) is fixed, applyPostSyncPreservation's own
   postFm/applyStatePreservation/authoritativeFm-reassertion machinery
   re-extracts frontmatter from syncedContent, restores curated fields
   from the pre-write snapshot, and reconstructs a NEW block again —
   confirmed live via `state begin-phase`, which still lost the markers
   after fixing (1) alone.

Both are now guarded by the same predicate (isUnparseableFrontmatter,
checking FRONTMATTER_UNPARSEABLE): when the ORIGINAL frontmatter did not
parse and the caller is not on ADR-3408 §8.3's closed "body wins" list,
both functions return their input content unchanged rather than
re-deriving over it. The closed list (cmdStateSync #905,
/gsd-health --repair's REGENERATE_STATE, both routed only through
writeStateMd, which never reaches applyPostSyncPreservation and passes
sanctionedPermanentEmptyFallback=true to syncStateFrontmatter) is
untouched — neither widened nor narrowed; verified by execution that
`state sync` still overwrites the conflict-marked block exactly as before.

Other verbs sharing the same readModifyWriteStateMd path were checked and
were equally affected before this fix: state update, query state.patch,
and state begin-phase all lost the conflict markers (RED, shown by
execution), and all three now preserve them (GREEN). Covered table-driven
in tests/feat-3881-yaml-parser-consequences.test.cjs's new A2b describe
block, which drives the real CLI verbs via runGsdTools — not just the pure
transitionCore layer the earlier A2 rows exercised — plus a control
asserting state sync's body-wins contract is unchanged.

Refs #3881

* fix(#3881): restore the parse surface's prototype and fix remote-runner failures

Root cause of the bulk of the 88 remote-runner failures: extractFrontmatter/parseGuardedYamlRegion handed back Object.create(null) trees for prototype-pollution safety, but assert.deepStrictEqual compares prototypes, so every assertion against a plain object literal failed (57 frontmatter.unit.test.cjs + 5 frontmatter.test.cjs + others). Fixed by keeping the internal construction null-prototype (unchanged) and converting to a plain-prototype tree via Object.defineProperty (never bracket assignment, so __proto__/constructor/toString keys stay safe) at the parseGuardedYamlRegion/unparseableResult return boundary only; the internal FULL_LINE_COMMENTS Symbol channel is copied by reference, not recursed, so its own __proto__-safety is untouched.

Per-class fixes: (1) bomAcrossArtifactTypes was the same prototype bug, no separate code change needed. (2) frontmatter-cli #1660: added objectListFieldWouldLoseData, a broader lossy-field detector alongside the existing byte-identical noOpObjectListSetError -- js-yaml's flattenObjectListItem now correctly includes every sub-key of an object-list item (a real bug fix over the legacy scanner, which silently dropped every field but the first), so a set that drops that now-included data is no longer byte-identical to the original and needs its own guard. (3) uat.test.cjs: updated the pinned expectation for the human_verification quote-stripping artifact -- js-yaml resolves quoting correctly where the legacy regex left an unbalanced quote; documented as an intentional, non-lossy behavior change. (4) smart-entry: added a fallback-only loadWithAmbiguousColonRepair so a column-0 key: value line whose value itself contains an unquoted colon (the #2571 hand-edited-STATE.md shape) round-trips instead of failing the whole frontmatter block closed. (5) frontmatter.unit.test.cjs bracket-array leniency: added a second fallback, repairMalformedInlineArrays, restoring the legacy scanner's tolerant inline-array handling (consecutive/blank commas, unclosed bracket) -- both repairs run ONLY after the primary parse already threw, so well-formed documents are unaffected. (6) prompt-injection-scan: src/frontmatter.cts had a literal U+FEFF BOM embedded in a comment illustrating the #2977 fix; replaced with the U+FEFF text escape. (7) eslint-glob-coverage: allowlisted the new src/vendor/js-yaml.d.cts vendored type declaration, same precedent as the existing re2js.d.cts entry. (8) frontmatter-golden-parity: git ls-files *.md now runs with -c safe.directory=* (process-scoped) so it survives the remote runner's dubious-ownership check without a persistent git config write.

* test(#3881): make golden parity resistant to unrelated tree churn

A corpus-wide snapshot keyed to every tracked *.md file was coupled to mutable-by-design files: .changeset/*.md's pr:0 -> real-PR-number backfill is a required workflow step, not a parser change, yet it turned this suite red. Training people to 'just regenerate the golden' on that kind of failure defeats the point of the snapshot. Exclude .changeset/** from the golden corpus entirely, tolerate tracked *.md files with no golden entry (they postdate the capture) instead of failing on them, keep hard failures for a golden entry whose file has vanished from the tree and for any real parity divergence, and add a coverage floor so the enumeration cannot quietly degrade to comparing a handful of files. Golden regenerated by recompiling the legacy pre-migration parser (git show ddde001af:src/frontmatter.cts) standalone, independent of the current parser, over the same non-changeset corpus.

Refs #3881

* test(#3881): make the parser golden hermetic instead of tree-keyed

This repo merges ~21 commits/day; a 14-day sample measured 937 touches of the
exact files (commands/gsd/*.md, gsd-core/workflows/*.md, agents/*.md,
docs/*.md) the prior golden pinned by tracked path. Any PR editing one of
those files' frontmatter for reasons unrelated to the parser (an
argument-hint addition, an allowed-tools tweak) turned the suite red, and the
reflex fix -- "regenerate the golden" -- overwrote the very snapshot meant to
catch a real regression. Excluding .changeset/** was not enough; the design
itself was wrong: a regression fixture must not be keyed to mutable repo
paths, and a single 376-entry JSON every such PR touches is also a
guaranteed merge-conflict surface.

Rebuilt the fixture to carry its own documents: each of 51 entries stores a
stable id, literal documentText (shrunk from a real ddde001af-era corpus
document), and an expectedParse captured independently from the
pre-migration legacy parser (git show ddde001af:src/frontmatter.cts,
compiled standalone against its byte-identical sibling modules). The test
reads no tracked path, shells out to no git command, and enumerates no tree
-- a PR editing commands/gsd/help.md cannot affect it. Every entry's
reconstruction was verified at capture time to reproduce both the current
and legacy parser's output on the original document; 0 of 51 candidates
were dropped by that check (1, the deliberately-unterminated
unclosed-block.md adversarial fixture, has no closing fence to truncate at
and is stored unshrunk). Kept the 5 documented DIVERGENCES rows (now
diverges:true entries) and the D2 order-preserving structural serializer
that keeps the comparison from passing vacuously; dropped the
tree-enumeration helpers, the coverage floor, the post-capture-skip logic,
and the vanished-file check -- all artifacts of the path-keyed design.

Refs #3881

* fix(#3881): resolve vendored-deps paths independently of cwd shape

Five rows in tests/lint-vendored-deps-manifest.test.cjs failed on
windows-latest CI: the test passed absolute scratch-file paths into
compareFiles()/checkRow(), whose helpers joined every input onto ROOT
via path.join(ROOT, rel), producing garbage when the input was already
absolute. It surfaced on windows-latest specifically because GitHub's
Windows runners checkout the repo on a different drive than TEMP, so
path.relative(REPO_ROOT, tmpFile) returned the absolute path unchanged
(no relative traversal is representable across drives) rather than the
relative form the test assumed. The remote gsd-test runner this repo
gates pushes on is Linux-only and could never have caught this;
GitHub CI's windows-latest job is the only signal that does, and it did.

Fixed the helper itself (scripts/lint-vendored-deps.cjs's new
resolvePath()) to treat an already-absolute input as absolute-in,
absolute-out instead of silently mis-joining it, and updated the test
to pass the scratch file's absolute path directly rather than relying
on a relative conversion that is not always representable. Kept every
mutation-sensor assertion intact and added coverage proving
resolvePath is a no-op for relative inputs and correctly passes
absolute ones through unchanged.

Refs #3881

* fix(#3881): warn when state sync regenerates over unparseable frontmatter

state sync (ADR-3408 §8.3's sanctioned regenerate path) correctly
overwrites an unparseable frontmatter block per its 'body wins'
contract — that overwrite behavior is unchanged here. The defect was
the silence: synced:true/exit 0 gave no signal that the existing
block (including git merge-conflict markers) could not be parsed and
was destroyed, per ADR-3473 §8.5 ('a derived conclusion may not be
reported as authoritative when the derivation dropped input it could
not resolve') and §8.4 ('failure is a value').

Adds a gsd: warning — ... (#3881) line on stderr, matching the
existing #3573 precedent, and surfaces the same disclosure in the
JSON result's existing changes[] array so a machine consumer sees it
too. Exit code and synced:true are left unchanged — sync did what its
contract says.

REGENERATE_STATE (/gsd-health --repair's sibling on the same
sanctioned-regenerate list) is DESTRUCTIVE-risk and unconditionally
refused by applyRepairs's dispatcher before runRepairAction ever runs
(src/health-diagnostic.cts), so it is not a live path today and is not
in scope for this fix.

* revert(#3881): restore exit-0 result envelopes for state errors

Reverts 9638f2936 and its changeset. The change was wrong and the revert is
the correction.

This repo distinguishes two error mechanisms deliberately. error() in
src/io.cts writes to stderr and calls process.exit(1) -- the hard-failure
path. output({error: ...}) writes a JSON result envelope to stdout and returns
normally with exit 0. The reverted commit converted 23 result-envelope sites
into hard failures, which is a different contract, not a bug fix.

tests/state-contract.test.cjs's errorPathDoesNotPublish asserts the envelope
contract directly -- a failing command exits 0 with a JSON error envelope and
must not publish state.json -- and the remote matrix run caught it along with
four cases in the QA scenario walk. Thirteen tests in tests/state.test.cjs that
the original commit rewrote were encoding that real contract, not the bug it
claimed; they are restored.

Whether an error envelope on stdout with exit 0 is the right CLI design is a
genuine question, and it is section 8.4's rule ('failure is a value') with its
own phase. It is not something to flip inside this PR.

* test(#3881): keep the frontmatter mutation shard inside its time budget

The Stryker (frontmatter) shard hit the documented 15-minute (900s) shard
cap. Root cause is NOT row-level spawn overhead (contrast the #2790/
core-utils precedent): the three shard test files' own logic runs in
~413ms total (356+30+27ms) with all 392 assertions passing. Instead,
src/frontmatter.cts grew from ~825 to 1496 lines (+671/-187) migrating to
the vendored YAML parser, proportionally growing the mutant count Stryker
generates for gsd-core/bin/lib/frontmatter.cjs. Stryker's command runner
bills the full 'node --test <3 files>' invocation once per mutant, and
node:test's default per-file process isolation forks a child process for
each of the three files on every one of those invocations — pure fork
overhead multiplied by a much larger mutant population.

Fix: scripts/mutation-matrix.cjs COVERED.frontmatter now declares
isolation: 'none', and .github/workflows/mutation.yml passes
--test-isolation=${{ matrix.isolation }} (defaulting to 'process' — i.e.
unchanged behavior — for the other 8 shards, which were not individually
audited for cross-file state leakage under shared-process execution).
Measured locally via node:test's run() API on the exact 3-file set:
isolation:'process' took ~593ms vs isolation:'none' ~478ms for the same
392 passing assertions. The true CI-shard number can only be confirmed
on the GitHub Actions run (Stryker cannot run locally, and 'node --test'
is hard-blocked in this environment).

Refs #3881

* test(#3881): register the vendored-parser tests in the frontmatter mutation shard

stryker.config.mjs's own rule ("Keep this list in sync with the tests
arrays in scripts/mutation-matrix.cjs COVERED") was violated: #3881 grew
src/frontmatter.cts from ~825 to 1496 lines but its new tests
(tests/feat-3881-yaml-parser-consequences.test.cjs,
tests/frontmatter-golden-parity.test.cjs,
tests/frontmatter-roundtrip.property.test.cjs, and +167 lines in
tests/frontmatter.test.cjs) were never added to the frontmatter shard's
tests array, so Stryker's mutants in the new vendored-js-yaml adapter had
nothing constraining them. PR #3888 measured 55.8% against the 65 floor
(748 killed / 593 survived / 17 timeout) and the shard was separately
cancelled at 15m04s against the 15-minute per-shard cap.

Registers all four files (each earns its slot on evidence of a unique
constraining assertion, documented inline), gives the shard a
measured/projected 180-minute budget via a new per-module
timeoutMinutes field threaded through mutation.yml's job-level
timeout-minutes the same way isolation is threaded, and removes the
prior isolation:'none' override (re-measured at this file-set size, its
savings are within run-to-run noise, not worth the unaudited
cross-file-state-leakage risk).

Closed the frontmatter shard's 63.03%-vs-65 gap with new behavioral tests in
tests/feat-3881-yaml-parser-consequences.test.cjs, each paired with a documented
near-miss: frontmatterDeepEqual's array-order/length/type-mismatch/key-order
semantics (via spliceFrontmatter's no-op guard), scalarNeedsDoubleQuoting's
leading/trailing-whitespace and dash/surrogate triggers (via reconstructFrontmatter),
repairAmbiguousColonValues' already-quoted vs ambiguous-colon repair paths (via

Add an injectable --matrix seam to scripts/check-mutation-score-ratchet.cjs and point the CLI rows at a synthetic module + synthetic floor built via a temp fixture, so the rows are indifferent to any real module's floor moving while still exercising the same fail/pass behaviour.

Restores the function plus its post-throw fallback path (loadWithAmbiguousColonRepair) only; repairMalformedInlineArrays and splitLegacyInlineArrayItems stay deleted, reverified against the full frontmatter test shard. Adds a frontmatter-level regression row in tests/feat-3881-yaml-parser-consequences.test.cjs so the dependency is visible where the function lives.

ddde001af6 enhance(#3873): the STATE.md schema — one owner, generated artifacts (#3880)
* test(#3873): failing-first locale parity, plus tripwires for what must not move

Pins ADR-3473 §8.8 at the artifact a reader actually sees. The English STATE.md
reference carries a Status lifecycle section that is missing from all four
translations — the section documenting the status enum whose clobbering is
#3853. The test derives the heading set rather than hard-coding the missing
one, and names the locale and the heading when it fails.

Two tripwires that must pass today and after. The field-drift guard still
catches a re-derived fallback ladder: §8.8 instructs deleting that script, and
that instruction rests on a wrong premise about what it guards, so the test
stops a future reader from deleting it on the ADR's word. And last_activity's
label resolution is pinned to what ships today, because it is declared in one
of the two tables this phase consolidates and not the other — the
consolidation must not silently pick a side.

The locale test buckets under docs rather than state, which is what it tests;
that bucket is allowlisted with justification rather than folded into an
unrelated docs suite. It reads only markdown, so it carries no allow-test-rule
marker — a marker there would suppress nothing and would grow the unverified
pool against its ceiling.

Refs #3873

* feat(#3873): one schema owns the STATE.md key set, three tables become projections

ADR-3473 §8.8. The key set was declared in four places that had to agree by
hand and already did not: FIELD_CLASSIFICATION, FRONTMATTER_BODY_SOURCE,
FRONTMATTER_KEY_TO_BODY_LABEL and buildStateFrontmatter's emit behavior. One
frozen null-prototype schema now declares each key's type, enum, cardinality,
source, preservation, body source, body label, accepted parse shapes and
whether it is emitted unconditionally; the three tables are derived from it at
module load.

The projections are byte-identical to the literals they replace, key order
included, and the parity tests compare against verbatim copies of today's
tables rather than re-deriving both sides from the schema — a parity test fed
from one source proves nothing, which is how a consolidation ships a changed
policy under a green test.

last_activity was the live disagreement: present in one table, absent from the
other. The schema declares what ships today rather than the tidier answer, and
a test pins it.

The schema is a leaf module and owns the four field-policy types, re-exported

health-diagnostic-types made to break a CJS require cycle.

* feat(#3873): generate the schema-derived regions, parity-check the prose tables

ADR-3473 §8.8's generator half. gen-state-md-docs.cjs owns marked regions in
the shipped template and all five reference docs, follows gen-features.cjs's
fail-closed contract, and is wired into regen:derived and lint:generated-sync.

The Status lifecycle section was missing from all four translations — the
section documenting the status enum behind #3853 — and is now generated into
every locale. Field cardinality is a new generated table: pure schema data,
no prose, so nothing to lose.

The Field-reference and Status-values tables are parity-CHECKED rather than
generated. Their Purpose, When-populated and Matched-text columns are
genuinely hand-translated per locale, and §8.8 itself says prose stays
hand-translated; generating them from an English registry would overwrite four
locales' translations on every write. The row set is checked against the schema
instead, so a key added to one and not the other fails, which is what field
drift actually means. Building that check found last_activity_desc
undocumented in all five tables.

Three keys the docs describe are absent from the schema — active_phase,
next_action, next_phases. They are grandfathered by name, not by wildcard, so a
fourth fails: a declared gap with a forcing function rather than a silent one.

Refs #3873

* fix(#3873): declare what the parsers do, and close the shape-parity gap

Two declarations in the new schema described intended behavior rather than
actual — the defect class this epic exists to end, committed inside the epic.
Both were caught by executing the parsers instead of reading their docstrings.

current_plan.acceptedShapes claimed ['N', 'N of M']. Standalone, the hybrid
shape errors; the path that looks like support is parseInt truncating '2 of 5'
to 2 and discarding the rest. Narrowed to ['N']. The parser is deliberately NOT
fixed here: that is #3784 and PR #3791 is already doing it. When #3791 lands
this row must widen, and the shape test will go red until it does — the schema
and the parser cannot drift apart quietly, which is what §8.8's checked-not-
generated rule is for.

STATUS_LIFECYCLE_ENUM claimed to be the closed set status can hold.
normalizeStateStatus passes unrecognized prose through unchanged, so it is not
closed at runtime. The seven members are the canonical values it maps onto; the
docstring now says that and the test asserts the real lenient contract.

Closes the acceptance item that a test asserts the parsers accept exactly the
declared shapes: the check is table-driven over every row carrying
acceptedShapes, guarded against passing vacuously on an empty set, and fails
loudly if a future row has no registered driver. Adds the unwired-label throw
and the fast-check property that every projection agrees with its schema row.

Refs #3873

* fix(#3873): keep the shipped template's frontmatter first, and make row 27 able to fail

The remote matrix caught 12 failures with one cause. Making the template's
frontmatter a generated region wrapped it in its own yaml fence ahead of the
markdown fence, so extractFileTemplate and readShippedStateTemplateBody — which
both match the single markdown block — found the heading first, not the
frontmatter. That breaks the contract every new project's STATE.md is created
from: bug #21 and epic #1969 B8 pin that the File Template block starts with
frontmatter and carries gsd_state_version.

The markers now sit inside the single markdown fence, so the fence opens before
the frontmatter and the region still ends ahead of the heading. Same layout as
before this phase, with markers embedded rather than a second fence.

Row 27 existed to catch exactly this and did not, because it was writer-seeded:
it asserted against the generator's own output shape, so it passed on the broken
template. It now parses the fence the way production does and was verified to
fail against the broken shape before being trusted against the fixed one. A test
that would not have caught the bug it exists to prevent is worse than no test.

The emitted-attribution failure was separate and the fragment was the wrong
remedy: gsd-core/templates/state.md self-attributes under a verbatim-copy
identity rule, so a diff touching it needs no acknowledgment. Fragment deleted
rather than left explaining nothing.

* docs(#3873): how to change the STATE.md schema

The phase gate was right and my docs artifact was wrong. I listed
lint:generated-sync as the second enablement step, which is a verification
command dressed as one, and then claimed a one-step sequence owed no how-to.

The real sequence is build:lib then regen:derived, and the ordering is a trap:
the generator reads the COMPILED schema, so regenerating before building
regenerates against the previous schema and commits artifacts that look
plausible while disagreeing with the code just written. A reference table
cannot carry an ordering dependency; that is what the how-to test is for.

The page covers adding, changing and removing a key, every reason code the
check emits and what to do about each, what is generated versus hand-translated
and why the two prose-bearing tables are parity-checked instead of generated,
adding a language, and the three grandfathered keys. Indexed from docs/README.md.

fb2d122d7f feat(#3841): assert gsd-tools identity on every state-mutating verb (#3848)
* feat(#3841): assert gsd-tools identity before any state-mutating verb

only this package publishes. The path-based branches — a project-local install,
a runtime config directory — had no such guarantee; they trusted their
configured location. This closes them.

Mechanism: once resolution finishes, and before any verb runs, the preamble
probes the tool it picked with `runtime-identity --raw` and matches the answer
with a shell `case` pattern ANCHORED to the start of the compact payload
(`{"packageName":"@opengsd/gsd-core"`). An unanchored substring match accepts
the decoy `{"packageName":"get-shit-done-cc","note":"@opengsd/gsd-core"}`, which
any colliding package could publish. The outcome is exported as the two-valued
`GSD_IDENTITY_STATUS` (`ok`/`unverified`), so the gate is asserted on a VALUE
rather than on warning prose. Rollout is warn-then-fail per the #3146 ruling:
`unverified` prints one line naming BOTH causes and continues, because
`no_identity_verb` cannot tell a foreign package from an `@opengsd/gsd-core`
older than the verb, and at rollout the old-version case is the common one.

The blocker was byte budget, not design. The preamble is inlined into 112
shipped files and several sat within single-digit bytes of frozen ceilings
(`gsd-verifier.md` 16 bytes, `gsd-executor.md` 33, `execute-phase.md` 234); a
first attempt broke five of them. What made room was collapsing the resolver's
twenty near-identical `elif [ -f … ]` arms into one candidate-list helper
(`_gsd_at`), which buys far more than the assertion costs. The preamble is now
2,624 bytes against 4,500 — a net 1,876 bytes SMALLER per inlined file, so every
capped file moved away from its ceiling rather than toward it. No cap raised, no
size-budget exception added, no override token emitted.

Resolution order, every runtime-home probe, the `unset -f gsd_run` re-source
fix, the fail-closed `exit 1`, and the `CLAUDE_ENV_FILE` persistence are all
preserved byte-for-byte in substring terms; the snippet still begins with
`_GSD_SHIM_NAME=` and still ends with `fi`, which the parity extractors anchor
on. `gsd-core/references/gsd-run-resolver.md` is re-synced byte-equal.

Also fixes two stale claims found in passing: CONTEXT.md and FEATURES.md both
described an `[ -x ]` guard as the load-bearing re-source defense. That guard
was tried and REMOVED in #3831 — it rejected the bare function name, fell
through every branch, and hit `exit 1`, which kills a sourced caller's shell.
`unset -f gsd_run` is the actual mechanism.

* fix(#3841): pair the anchor's brace by requiring a closed identity payload

The matrix went red on `tests/new-project-mvp-prompt.test.cjs` — "new-project.md
has unbalanced braces: net depth 2" — plus a knock-on report from its parent
`bug #1516` describe, which is the same failure counted once at the child and
once at the block.

Root cause: that guard (:182-189, mirroring #3784 bd53925f) walks characters and
increments on `{`, decrements on `}`, with no awareness of shell quoting. It
scans `new-project.md` PLUS every `new-project/steps/*.md`, and both
`new-project.md` and `steps/auto-mode-config.md` carry one inlined preamble copy
— hence net 2 from a snippet that was off by exactly one. The unpaired brace was
the `{` inside the single-quoted `case` pattern of the identity anchor, which is
correct shell and invisible to a text scanner.

Fix in the snippet, not the guard. The pattern now anchors at BOTH ends:
`'{"packageName":"@opengsd/gsd-core"'*'}'`. That balances 51/51 with a brace that
does real work rather than a cosmetic pair — a truncated payload whose prefix
matches now fails too, where before it verified. Safe for any future additive
field: a JSON object's own closing brace is always the last character, whatever
type the last value has, which is pinned by two negative-space tests (a nested
object and an array-valued last key must both still verify). Cost: +3 bytes,
against the 1,873 the resolver fold already gave back.

The alternative considered and rejected was dropping the literal `{` for a `?`
glob. It balances too, but weakens the anchor from "must be an opening brace" to
"must be any one character", and the anchor is the entire point.

Two guards added so this cannot recur silently:
- runtime-launcher-parity (F0) pins brace balance at the SNIPPET, so the next
  edit to that pattern fails on the file it broke instead of surfacing three
  files downstream in a test whose name mentions neither the launcher nor this
  issue. It also asserts depth never goes negative, since a `}` preceding its
  `{` nets to zero while being unbalanced at every prefix.
- runtime-identity gains behavioral truncated-payload and trailing-garbage
  fixtures, so the added `}` is proven load-bearing rather than merely present.

Verified: snippet 51/51 braces; new-project combined net depth 0; the seven
other preamble-bearing files with nonzero depth are unchanged from merged next
(their own prose, not the preamble, and not in any guard's scan set); all 112
inlined copies and the resolver reference re-synced byte-equal; sync:launcher
idempotent on the second run.

63abcface9 feat(#3146): resolve gsd_run so workflows cannot reach a foreign gsd-tools (#3831)
* feat(#3146): resolve gsd_run so workflows cannot reach a foreign gsd-tools

The predecessor package get-shit-done-cc publishes a colliding gsd-tools bin whose phases.clear DELETES where this package's ARCHIVES, and both print success-shaped output against a gitignored .planning/ -- which is how #3129 cost a user 43 phase directories with no error and nothing recoverable from git.

The launcher's PATH branch now resolves gsd_run, published only by this package and self-locating via its own symlink chain to the sibling shim, instead of the colliding gsd-tools. A foreign handler becomes unreachable from PATH, and when no gsd_run is reachable the resolver fails closed rather than falling back -- that fallback was the vulnerability. This is smaller than the branch it replaces, which matters: the preamble is inlined into 113 shipped files and agents/gsd-verifier.md sits 2 bytes under a red-line size cap.

unset -f gsd_run leads the preamble so a re-source is idempotent. Without it, command -v finds the shell function, returns a bare name, and the resolver falls through to an exit 1 that kills a sourced caller's shell.

Adds gsd-tools runtime-identity, a manual diagnostic reporting this runtime's package coordinates over the baked package-identity (#498) and readHostVersion, with a strict total classifier: only a JSON object with an exact packageName verifies, since JSON.parse admits 0/"str"/[]/null/true.

An inlined identity assertion was built and reviewed first, then withdrawn -- it breaks five frozen size ceilings and no assertion fits in 2 bytes.

Closes #3146

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

* fix(#3146): stop sync:launcher relocating a deliberate preamble placement

Pre-existing defect, surfaced by this PR because sync is a no-op unless the snippet content actually changes. transformFile inserts the preamble into the first block that CALLS gsd_run, but gsd-core/workflows/explore.md deliberately places it in a bootstrap-only block that DEFINES gsd_run without calling it -- its own comment explains why: declining the research offer must not leave Step 5's commit call unbootstrapped. Stripping empties that block of calls, so the preamble migrated forward and broke the define-before-use invariant tests/explore-command.test.cjs pins.

Reproduced on a pristine origin/next checkout with the base snippet and base file, so this was not introduced here. The insertion target now honours a block that already carried the preamble, falling back to the first calling block for files that have none yet. Adds a behavioral regression test over a two-block fixture.

Also updates three runtime-launcher-parity tests that pinned the removed PATH fallback to gsd-tools. Their intent is preserved -- the PATH stub is renamed gsd_run so it is reachable by the new resolver, and the RUNTIME_DIR-wins test still asserts the stub is never invoked. Fixture shebangs move to an absolute /bin/sh, because the fixture PATH is deliberately restricted and #!/usr/bin/env sh could not resolve.

* docs(#3146): document the FEATURES.md section-numbering practice

The monotonically increasing section number in docs/FEATURES.md is the most frequent merge-conflict source in this repo, and it has TWO conflict cells, not one: the ### N. heading and the hand-maintained table of contents. Two PRs adding differently numbered features still collide on the TOC, so renumbering alone does not make a branch safe. This branch alone was renumbered 165 -> 166 -> 167 -> 168 across successive rebases.

Adds a CONTRIBUTING section stating the practice: allocate the number last, never pre-emptively renumber, take max+1 after a rebase and update the TOC in the same commit, and never renumber someone else's section. Fork contributors are told explicitly they may leave the number to a maintainer at merge rather than chasing the counter. Agents are told to lease the allocation and to include the file in their published touched set.

Records the durable fix as planned rather than pretending it exists: FEATURES.md should be generated from per-feature fragments the way CHANGELOG.md is generated from .changeset/, and the way tests/emitted-drift-acks/ works (#2914).

Also renumbers this branch's own section to 168, leaving 167 to the PR already in flight.

c933184b97 enhance(#3172): require a stated failing direction for every automated acceptance command (#3825)
* test(#3172): failing-first suite for the stated failing-direction probe

Pins the <fails_when> pairing walk, placeholder denylist, MISSING sentinel
exemption, degraded-read contract, CLI arm and the plan-authoring contract text.
RED by construction: the module exports it requires do not exist yet.
Executed on the remote runner.

* feat(#3172): require a stated failing direction for every automated acceptance command

Every runnable <automated> command now carries a <fails_when> sibling naming
what output constitutes failure. A command with no expressible failure mode is
not an acceptance test: it reads as rigour and is not falsifiable.

- verify-command-grounding gains a failing-direction probe sharing the existing
  <automated> grammar, MISSING sentinel and walk guard rather than copying them
- gsd-tools check verify-failure-directions <N> backs it; plan-phase dispatches
  it and hands the JSON to gsd-plan-checker check 8f
- Dimension 8 detail extracted to references to stay under the agent size cap

Verified on the remote runner.

* fix(#3172): close four review findings in the failing-direction probe

- MISSING_SENTINEL_RE matched an env-var assignment prefix (MISSING=1 cmd), so
  a real command was exempted from the new blocking gate. Tightened the SHARED
  constant rather than adding a second copy.
- Both token regexes scanned to EOF on unclosed openers (O(n^2), 1562ms at 40k).
  Bodies are now non-crossing; 1ms, byte-identical on well-formed input. The
  pre-existing AUTOMATED_BLOCK_RE carried the same defect and is fixed here too.
- probePhaseFailingDirections reported status 'ok' when one plan was unreadable,
  conflating 'could not look' with 'nothing to report'.
- Extracted the phase-resolution block both check arms had copied verbatim.

Also corrects a docs/AGENTS.md dimension list stale since #2401.
Verified on the remote runner.

* fix(#3172): project the planner rule onto the spawn contract, settle emitted bookkeeping

The remote runner refuted the planner-side edit. agents/gsd-planner.md is frozen
under a 49152-LF-char cap asserted by four suites and sat at 49,146 — six chars
of headroom — so the +537 of authoring rule blew it. #3297/#3645 already settled
where such a rule goes: the planner spawn contract in plan-phase.md, beside
<tracked_source_paths>. The agent file is reverted to origin/next verbatim.

- plan-phase.md gains <failing_direction_contract>; tests row 30 now asserts the
  contract there and row 30b guards the freeze in both directions
- plan-phase.md growth acknowledged by APPENDING to the 3409 fragment, per the
  precedent that two ack sources may never name the same path
- install-tree fixtures regenerated for the three new reference files

Verified on the remote runner.

596540f864 feat(#3227): publish machine-readable state contract at step boundaries (#3824)
* feat(#3227): publish machine-readable state contract at step boundaries

Adds src/state-contract.cts, a best-effort publisher that writes
.planning/state.json (contract 1.0.0) at 11 step-boundary commands, so
external tools read a versioned contract instead of parsing STATE.md and
ROADMAP.md heuristically.

Composes existing owners rather than re-deriving: phase rows come from a
new locateProgressTable extracted from deriveProgressFromRoadmap (so the
snapshot can never disagree with GSD's own progress counters), milestone
identity from getMilestoneInfo, and next from classifyProject. Owners are
required lazily to avoid the state -> state-contract -> smart-entry ->
state require cycle.

Also fixes a pre-existing defect in scripts/lint-test-file-count.cjs
(maintainer-approved as a second concern): testEffectivePrefix never
stripped the suite qualifier, so 65 dotted test files counted against no
module and 9 mis-bucketed into a shorter one. Allowlist re-baselined for
the 74 files the gate can now see.

injection flavor is illustrative, not load-bearing.

Reshaped to a hyphenated fake instruction tag, which stays hostile-looking
while matching none of the scanner's patterns. Allowlisting the file was
rejected: that mechanism is for suites whose subject IS injection defense,
and it would blind the scanner to this whole file permanently.

The module was registered at minScore 50, the ratchet's minimum permitted
floor for a newly-registered module whose score had not been measured. This
PR's own Stryker shard measured 66.25% (run 32769289750, job 97565813640),
so the floor moves to floor(measured) - 1 = 65, per the rule the registry
documents.

66.25 is below TARGET_MUTATION_SCORE (80), so this stays a ratchet
candidate: raise as the tests improve, never lower.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

a44d513566 fix(#3712): confine in-process installs to a sandboxed HOME (#3725)
* fix(#3712): confine in-process installs to a sandboxed HOME

A runtime kind may declare a global `home` override resolved from os.homedir()
rather than from the caller's configDir — codex's skills kind (`home: ".agents"`,
ADR-1239 / #2088) is the only live case. Sandboxing configDir/targetDir does not
contain it, and assertDestWithinConfigHome cannot see the class: that gate
confines a destSubpath to whatever root it is handed, and here the root IS the
escaped home. So an in-process caller that forgot to sandbox HOME wrote to, and
pruned gsd-* entries from, the developer's REAL ~/.agents/skills.

tests/agent-descriptor-parity.install.test.cjs's K1 loop did exactly that: it
iterates every agents-kind runtime (codex included) with a sandboxed targetDir
and an un-sandboxed HOME. Reproduced against a canary home on next @ adb46cdd8 —
71 gsd-* skill dirs deleted, a foreign `cloudflare` skill surviving, suite still
exit 0. It is silent because the runtime's own config home is untouched, so the
manifest keeps reporting a healthy install.

FIVE writers resolve a kind `home` and then destroy under it. Three are reachable
today — installRuntimeArtifacts, uninstallRuntimeArtifacts (install-engine.cts)
and applySurface (surface.cts). Two are descriptor-dependent and guarded against a
future descriptor change rather than a present escape: installOpencodeFamilySkills
(behind the combined-family early return) and installAgentsKindStandalone. Those
two are scoped to the single kind each destroys — passing the whole layout made
codex's unrelated skills override trip a writer that never touches it.

- src/test-home-guard.cts: refuse when a run under a test runner cannot be shown
  to have sandboxed HOME. NODE_TEST_CONTEXT (set by `node --test`) gates it, so
  installs outside a Node test context are untouched; GSD_TEST_MODE is unusable,
  as several candidate files including the offender never set it. Homes are
  compared by FILESYSTEM IDENTITY (st_dev + st_ino), not by pathname:
  path.resolve() resolves neither symlinks nor case, and realpath returns a
  canonical pathname that two routes to one directory can still disagree on (bind
  mounts). Verified on macOS/APFS — HOME=/users/<name> made the strings differ
  while naming the same directory, and the lexical form ALLOWED a write into the
  physical real home. FAILS CLOSED: a pair is "different" only when both identify,
  or one is definitively absent (ENOENT/ENOTDIR) while the other identifies; every
  other errno is "cannot tell" and refuses. Only when neither home identifies is a
  marker consulted, and it carries the sandbox PATH and must equal the home in
  effect — a boolean checked first let an ambient or stale value disarm the guard.
- helpers: promote sandboxHome() out of its two byte-identical private copies,
  which is also what makes them record the sandbox; the three withFakeHome()
  helpers record it too. The marker NAME is duplicated as a bare string rather
  than required from the compiled guard, keeping helpers.cjs's documented
  no-built-lib-at-import-time contract; a test pins the two together.
- agent-descriptor-parity: sandbox HOME across the K1 loop.
- helpers-process-isolation: #3156's canary asserts on <home>/.gsd only, and its
  `--cursor --local` spawn cannot reach `.agents` at all, so an assertion added
  there would pass with all confinement removed. Add a discriminating row — a
  `--codex --global` spawn against a seeded ambient home — which also asserts the
  runtime still declares the override. Its check is a sampled inventory (dir names
  + each SKILL.md), not a tree compare.
- install-write-confinement: predicate rows through the deps seam, covering the
  symlinked HOME, ambient and stale markers, and each sameDirectory branch
  (both-identify, one-absent, neither-identifiable), plus wiring rows that drive
  the REAL entrypoints so deleting a guard call site is red.

Verified: guard fires end-to-end against a real un-sandboxed HOME (exit 1, zero
deletions); the case-variant fail-open reproduced on APFS before the fix and
refuses after; K1 file 29/29 green with skills intact; mutation-tested — each of
the three reachable call sites, lexical-only comparison, and treating an unknown
errno as "absent" each take exactly one row red, with every mutation echoed back;
the process-isolation row negative-controlled by reverting installerEnv to its
pre-#3156 leak (16/0 -> 13/3); a full npm test leaves ~/.agents/skills at 71.

Stated residual: the two descriptor-dependent writers have no wiring test, because
no runtime declares a `home` override on those kinds and neither can be exercised
without inventing a descriptor.

* chore(#3712): add changeset

* fix(#3712): let a sandbox nested inside the real home through the guard

All six Windows shards of #3725 failed on legitimately sandboxed
destinations. On Windows os.tmpdir() is %LOCALAPPDATA%\Temp — inside the
user's home — so every sandbox a test creates is a descendant of the real
home, and "does this land inside the real home?" answers yes for the safe
case and the dangerous one alike. POSIX conceals this: /tmp and
/var/folders both sit outside $HOME.

Add the missing conjunct: a destination inside the real home is allowed
only when it also sits beneath a HOME that was sandboxed away from the
passwd home. Both halves are required — dropping the first re-admits a
plain un-sandboxed install, and dropping the second decays into the
"is HOME sandboxed?" check the module rejects, which a layout resolved
before the sandbox walks straight through. Each is mutation-proven by a
row that goes red without it.

Also covers the two fail-closed branches of the new exemption, which
survived mutation to `true` with the suite green, and avoids `<user>` in
a docblock — the prompt-injection scanner reads it as a delimiter tag.

* fix(#3712): close three writer/rollback gaps found reviewing the whole PR

Cross-AI review of the full PR (not just the round's delta) surfaced
three ways the guard could still be defeated:

- The nested-sandbox exemption trusted the SPELLING of a destination.
  With HOME sandboxed to a directory inside the real home — legitimate on
  Windows — an aliased `.agents` (symlink, junction, subordinate bind
  mount) beneath it redirected an allowed path into the real home. Decide
  containment on the path the write RESOLVES to: walk up to the nearest
  existing ancestor, canonicalize, re-append the tail.

- `migrateLegacyDevPreferencesToSkill` is a SIXTH writer that resolves a
  skills-kind `home` override. It creates rather than prunes, which is
  why it was missed, and `_runLegacyInstallMigrations` runs it before
  `installRuntimeArtifacts`' own assertion. Guarded, scoped to that kind.

- Worst of the three: `bin/install.js` snapshots the resolved skills root
  before installing, and its outer catch rolls back by deleting and
  recreating every snapshotted `gsd-*` directory there. The guard's own
  throw landed in that catch, so refusing an un-sandboxed codex install
  provoked exactly the mutation the guard exists to prevent. Refusals are
  now marked and rethrown without rollback — nothing was written, so
  there is no partial install to undo. Every other error still rolls back.

Also carries the sandbox marker into `installSpawnEnv`, so spawned
installers are not refused on passwd-less CI images, and corrects three
claims that no longer hold: "every writer" (six, and named), the
unconditional "fails CLOSED" (the passwd-less marker branch is a
deliberate weakening, and TOCTOU is out of scope), and the assertion that
Windows os.tmpdir() is always %LOCALAPPDATA%\Temp (Node honors TEMP/TMP).

* docs(#3712): name the guard's two limits instead of overclaiming

Round-2 review found the prose had drifted ahead of the code. Corrected,
with no behavior change:

- The module still said FIVE writers; there are six, and the sixth is
  now named along with why it was missed (it creates rather than prunes)
  and why it carries its own assertion (it runs before the main one).
- The canonicalization docblock listed subordinate bind mounts among the
  aliases it closes. It does not close them: a bind mount is not a link,
  so realpath keeps the mount-point spelling. `sameDirectory` already
  recorded that limit; the new helper now inherits it explicitly rather
  than contradicting it. Closing it needs mount-table introspection.
- "FAILS CLOSED" was unqualified while the passwd-less marker branch is
  a deliberate weakening — with no passwd entry, nothing can contradict a
  marker naming the real home.
- "Refuses BEFORE any write" was too broad: legacy install migrations run
  ahead of the layout-driven ones, which is exactly why the two
  rollbackInstallerMigrations() calls still execute before the rethrow.
  Only the codex skills-root rollback is skipped, and that is the only
  _codexPreConfigRollback() call site — applySurface is never called from
  bin/install.js and uninstall cannot reach it.

* fix(#3712): sandbox HOME in the opencode-family home-override parity rows

The last two Windows failures, and the same platform asymmetry in a
different disguise. This row drives a skills-kind `home` override on
purpose — precisely what the guard polices — but relied on the override
temp dir happening to sit outside the real home. It does on POSIX
(/tmp, /var/folders); on Windows os.tmpdir() is under %USERPROFILE%, so
the guard correctly refused and only Windows went red.

Declare the sandbox instead of depending on the platform: HOME becomes
the override itself, which is the home the call writes under. This is the
fix the guard's own message prescribes, applied to the test rather than
to the guard.

Both failing Windows shards fail on exactly these two rows and nothing
else; every other shard is green.

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

* fix(#3712): make sameDirectory answer NO when it cannot tell

Review Major 1. sameDirectory()'s only caller is the passwd-less marker
branch, which reads a `true` as permission to PROCEED:

    if (marker && sameDirectory(marker, osMod.homedir())) return;

The fallthrough returned `true` whenever neither side identified — two
absent paths, or two stats failing EACCES/EPERM/EIO on a locked-down
host — on the reasoning that "cannot tell" should make the caller refuse.
That reasoning was inverted with respect to this caller: it turned the
passwd-less escape hatch into an unconditional bypass for any marker
value at all, on precisely the hosts the fallback exists to serve. Only
two things now answer yes: one resolved pathname, or two readable
identities that match. Restoring the old fallthrough takes the new row
red.

Also from review:

- Major 2 asked whether st_dev/st_ino discriminate directories on
  Windows, where Node derives them from BY_HANDLE_FILE_INFORMATION. The
  whole guard rests on that primitive, so assert it rather than argue it:
  a row comparing two distinct temp directories, and one directory
  reached by two spellings. It runs on every platform in the matrix, so
  Windows answers the question itself.

- Minor 1: the refusal now names the real home it compared against, not
  just the destination it refused. That is the one fact needed to tell a
  true positive from a false one, and its absence is what made the
  Windows case a CI-log dig rather than a glance.

* fix(#3712): refuse a HOME that merely spells the real home more widely

Review round: one Blocker, four Minors, a Nit.

N2 (the one with teeth) — a destination's ancestor chain is linear, so
"inside the real home AND inside the effective HOME" admits two
arrangements, not one. The intended `effectiveHome ⊂ realHome` is the
Windows temp shape; `realHome ⊂ effectiveHome` — HOME at /Users, /home,
C:\Users — is not a sandbox at all, it is the real home reached by a
wider spelling, and it was exempting a stale destination pointing
straight at ~/.agents. Third conjunct added; the docblock no longer
claims two conditions suffice. Removing the conjunct reds the new row
and nothing else.

N4 — the migration guard resolved its OWN layout, and without
capabilityRegistry, so a registry-dependent descriptor could make it
vouch for a path the migration does not write: a guard reporting safe
while the unsafe write proceeds. It now guards the destination already
resolved by _resolveDevPreferencesSkillTarget, keyed on
`installRoot !== targetDir` — which is exactly the condition under which
a `home` override was declared, read off that same result.

N1 — CONTEXT.md gains the Test Home Guard Module glossary entry that
contributor-standards.md requires of a new Module. Not CI-enforced, so
green CI was never evidence it was met.

N3 — the docs/INVENTORY.md row was misfiled between install-fs-adapter
and install-model-override-resolver; the table is alphabetical and the
manifest already had it right. Moved, and its text now names six writers
and the third conjunct.

N5 — applySurface's signature docblock was two parameters stale; this PR
added the second of them.

N6 — the duplicated rollbackInstallerMigrations() adjacent to the new
rethrow: two identical consecutive calls, not two phases.

* fix(#3712): guard the sixth writer, and close two false-ALLOW paths

Review round 3 (NEW-1, NEW-2) plus three defects Codex found in the
whole-PR pass, each reproduced before it was fixed.

NEW-1 — migrateLegacyDevPreferencesToSkill called the guard with no
`deps`, so it bound real os/process.env and could not be wiring-tested
the way the other three reachable writers were. It now takes the same
optional `deps: { os?, env? }` tail parameter. The wiring block gains
the missing fourth row, and a fifth pinning the ALLOW half; the test
file's header docblock said "FIVE writers ... the three reachable
today", contradicting the six/four statement this PR already put in
src/test-home-guard.cts, CONTEXT.md, docs/INVENTORY.md and the
changeset. Both directions of the guard's condition now fail a row
when broken — previously neither did.

NEW-2 — derivesFromSandboxedHome's docblock claimed "THREE conditions
are required, and no two of them suffice". False for {2,3}: isInside is
reflexive, so whenever conjunct 1 fires conjunct 2 already returns
false on its own. Reworded as a fast path, which is what it is.

Codex 1 (false ALLOW) — on a host with no readable passwd entry the
marker branch returned as soon as the marker matched the effective
HOME. That attests a caller sandboxed HOME and says nothing about where
an already-resolved destination points, so a layout captured before
sandboxHome() — still naming the real ~/.agents — was waved straight
through: the same stale-layout shape the primary branch refuses by
design. The marker must now identify AND contain every destination.

Codex 2 (false ALLOW) — `installRoot !== targetDir` was the stand-in
for "the skills kind declared a home override". The two are not
equivalent: the inequality is false when the override resolves onto
targetDir itself, which is exactly a configDir of $HOME/.agents. The
guard was skipped and SKILL.md written into the real home under a test
runner. _resolveDevPreferencesSkillTarget now reports hasHomeOverride
off the same resolution instead of inferring it from two paths.

Codex 3 (prose) — the shared refusal message claimed every guarded
writer prunes; the migrate writer only creates. The changeset headline
claimed in-process installer calls can no longer reach the real home,
which is wider than the guard: writeNonClaudeDefaults still writes
~/.gsd/defaults.json through os.homedir(). INVENTORY's and CONTEXT's
fail-closed sentences omitted sameDirectory's pathname-equality
shortcut. All four narrowed to what the code does.

* fix(#3712): let the sandbox marker follow an overridden HOME

Found by Codex in the whole-PR pass. installSpawnEnv spreads
`overrides` last so an explicit HOME wins — deliberate, and its
docblock tells callers needing per-spawn isolation to pass their own
{ HOME, USERPROFILE }. But the #3712 marker was set before that spread,
so such a caller got HOME=<theirs> and marker=<helper default>. On a
host with no readable passwd entry the guard compares the two and
refuses a legitimately sandboxed spawn — tests/install.test.cjs:7143
and install-shared.cjs's own runInstaller both take that path.

The marker is now derived from the final HOME unless the caller
supplied one explicitly. The contract test asserted HOME after an
override but not the marker, which is why it stayed green.

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

* docs(#3712): name the shipped guard condition, not the deleted one

Review round 4 of #3725. Two artifacts this PR adds still described
`target.installRoot !== targetDir` in the PRESENT tense as the live guard
condition on `migrateLegacyDevPreferencesToSkill`. The shipped condition is
`runtime && target.hasHomeOverride` (src/install-engine.cts:510).

This is not ordinary doc drift. The named condition is the exact false-ALLOW
the previous round closed: a `home` override resolving onto `targetDir` — a
configDir of `$HOME/.agents`, which is where codex's override points — makes
the inequality FALSE while the override is declared, so the guard was skipped.
A maintainer reading CONTEXT.md:290 as authoritative would believe the guard
still skips that case.

  - tests/install-write-confinement.test.cjs — the ALLOW-half row's comment.
    Its "teeth" rationale is unchanged and still correct as written.
  - CONTEXT.md:290 — the Test Home Guard Module glossary entry, a documented
    PR gate. Now states the condition and names the inequality only as what it
    is NOT, with the reason.

The three surviving mentions of the inequality are all past-tense or negated
(src/install-engine.cts:448, :508 and the sibling test comment at :3698) and
are correct as they stand.

Verified: `npm run lint:ci` exit 0; full `npm test` 31327 tests / 31312 pass /
0 fail / 14 skipped, run with TMPDIR unset.

* fix(#3712): canonicalization fails closed, matching identify's errno split

Codex full-PR review of #3725, run against the round-4 head.

`resolveThroughLinks` caught EVERY realpathSync error and fell back to
`path.resolve(dest)` — the lexical spelling. That inverts the function's own
purpose. An aliased `<sandbox>/.agents` that cannot be canonicalized keeps its
sandbox spelling, satisfies the nested-sandbox exemption at :227, and the write
is ALLOWED into the real home — the exact escape this walk exists to close. The
module documents that it fails CLOSED with ONE named exception (the marker
branch); this was a second, unnamed one.

Split by errno, and deliberately by the SAME split `identify` already draws
rather than a second policy in one module — both answer "does this path exist
as named?", so they must not disagree:

  ENOENT / ENOTDIR -> walk up. The ordinary case: a fresh install resolves a
    destination nothing has created yet, so realpath fails on the leaf and on
    every not-yet-created ancestor. Refusing here rejects every install.
  anything else (EACCES, EPERM, ELOOP, EIO) -> refuse. The component exists but
    cannot be resolved, so the guard cannot tell where the write lands.

Three rows in the predicate block, beside the other aliasing rows:
  - a symlink CYCLE in the destination path (ELOOP)   -> REFUSE
  - a destination that does not exist yet (ENOENT)    -> ALLOW
  - a component behind a regular file (ENOTDIR)       -> ALLOW

Teeth checked against the artifact the test loads, not the source: reverting
the condition to the swallow-everything shape in the compiled
test-home-guard.cjs turns row 1 — and only row 1 — red. The ENOTDIR row caught
a stale build during development, which is the point of asserting on the
compiled file.

CONTEXT.md and the resolveThroughLinks docblock both record the new behaviour,
so this does not repeat the prose-vs-code drift the round-4 finding was about.

The changeset's existing scope sentence now bounds "six writers" to the
`installRuntimeArtifacts` call tree and names `cmdGenerateDevPreferences` —
which resolves the same codex `home` override through `getGlobalSkillsBase` and
writes SKILL.md beneath it unguarded. It has no in-process caller today (its
only direct require-and-call is a spawnSync with HOME sandboxed), so it is
latent rather than live, and whether it belongs in this PR is raised with the
maintainer rather than decided here.

Verified: `npm run lint:ci` exit 0; full `npm test` 31330 tests / 31315 pass /
0 fail / 14 skipped, TMPDIR unset.

* test(#3762): failing-first roster gate for docs/INVENTORY.md rows

Anchors the human half of the inventory-drift rule: every entry in
docs/INVENTORY-MANIFEST.json must have a hand-written row in

* fix(#3762): enforce docs/INVENTORY.md roster rows, backfill 32 gaps

docs/INVENTORY.md calls itself the authoritative roster of every shipped
GSD surface, and CLAUDE.md's inventory-drift rule requires both a roster
row and a manifest regen. Only the manifest half was anchored, so a PR
could ship a surface, regenerate the manifest, omit the row, and stay
green -- as PR #3758 did with gsd-core/references/planner-coupling.md.

Adds the roster half to tests/inventory-manifest-sync.test.cjs, backed by
a pure matcher in tests/helpers/inventory-roster.cjs, and backfills the 32
surfaces already missing rows on next.

* test(#3762): harden roster matcher against fenced blocks and trim exports

Skips fenced code regions when splitting level-2 sections so a documented
'## ' example inside a fence cannot truncate a family section (false red)

rather than a backtracking lazy match; narrows the module surface to the
three names the gate consumes.

* fix(#3762): close two false-RED gaps found in orthogonal review

Indented headings: CommonMark permits an ATX heading to carry 1-3 leading
spaces, and a ^##-anchored pattern read such a document as having no family
sections at all -- reporting all six missing, a structural red for zero real
drift. Reproduced, then fixed and pinned.

Link-wrapped cells: a row written as [`x.md`](../x.md) was not recognized,
though docs/INVENTORY.md already uses that form elsewhere. Unwrapping now
peels a whole-cell link and a whole-cell code span, and only layers that
wrap the cell entirely -- a file mentioned mid-prose is still not a row, so
the false red is not traded for a false pass.

Adds a second fast-check property over the commands source-link rule, the
one family whose matching rule differs from the other five.

prove a substitution had NOT executed, left behind when the run ended.
Nothing in the tree references it (verified by Grep across the repo),
package.json's files array excludes root-level files so it never shipped,
and lint-removed-but-needed confirms no surviving reference.

Found while auditing the repo root for #3762; fixed inline rather than
deferred, per CLAUDE.md's no-deferrals rule.

14679b866b enhance(#2856): add default-off live-DOM UAT capability (#3716)
* test(#2856): add failing-first suite for the live-dom-uat capability

Binds the approved triage shape before any of it exists:

- containment — the execute:wave:post hook must not render unless
  workflow.live_dom_uat is true AND the capability resolves active
  (fail-closed on a missing state entry, and on a non-boolean value)
- criterion 4 — agents/gsd-executor.md carries no browser MCP family;
  asserted as an absence, which is the only way it is observable
- Hyrum guard — the pre-existing mcp__playwright__* branch must stay
  outside the key-gated block, or upgrading silently removes working
  automated UI verification for every current Playwright-MCP user
- parity — the browser glob list now lives in two surfaces (agent
  frontmatter + workflow detection block); the assertion fails if
  either gains or loses a family without the other

Red by construction: the capability, agent and workflow block do not
exist yet. Verified on the remote runner.

Refs #2856

* enhance(#2856): add default-off live-DOM UAT capability

A phase whose acceptance criteria needed a live DOM could not be
finished by the agent that executed it: gsd-executor carries no browser
tools, so it correctly returned checkpoint:human-action even though the
work was not human-only, just tool-less. Every such phase degraded to
"executed, then finished by hand in the orchestrator", and autonomous:
false could not distinguish "a human must judge this" from "the executor
lacks the tool".

Implements the shape approved at triage, not the one reported. The
executor's tools: line is NOT widened, in any configuration: for a
first-party agent the static list is the only control that exists
(ADR-1244 D2, ADR-857 D4, no per-dispatch override). Instead one
default-off capability owns the key, the agent, and the step:

- capabilities/live-dom-uat/ — activationKey workflow.live_dom_uat
  (boolean, default false), one additive step at execute:wave:post
  (onError: skip, gates: []), so it can never halt a wave
- agents/gsd-dom-verifier.md — the only GSD agent carrying browser MCP
  globs, in its own tools: line, with no Bash
- verify-work automated_ui_verification — a gsd:live-dom-families block
  naming both new families AND the key; presence alone never activates

Two independent fail-closed gates: isCapabilityActive renders a hook
only on state.active === true, plus the step's own `when`.

The pre-existing mcp__playwright__* branch keeps the gating it already
had and stays outside the new block. Pulling it behind a default-off key
would have silently removed working automated UI verification from every
current Playwright-MCP user on upgrade.

Also closes a host gap this surfaced: execute:wave:post dispatched only
contribution + gate, so ANY registered step was declared and silently
never run — exactly the single-kind hand-roll loop-hook-dispatch.md
names. Step 5.75 now dispatches every kind == "step".

The browser-profile lock is tolerated, not coordinated: --isolated is a
flag on the operator's own MCP-server registration that GSD neither
launches nor parameterizes, so the verifier reports could_not_look /
profile_locked, names the flag, and stops. DOM-VERIFY.md keeps
could_not_look and nothing_to_report distinct behind a closed reason
enum — collapsing them is the ambiguous-run-notes defect reported.

Verified on the remote runner.

Closes #2856

* fix(#2856): apply review findings from the orthogonal passes

Correctness pass (blocker):
- delete detectionBlockIsCrlfSafe. It was pass-always: it read the file,
  replaced LF with CRLF, then indexOf'd marker strings that contain no
  newline, so the replacement could not change the result and the
  assertion could never fail for the reason it stated. There is no real
  CRLF risk on this surface either — the gsd:live-dom-families block has
  no parser, only human and agent readers. Deleted rather than replaced,
  per the repo's pass-always-test rule.

Isolated security pass (two minors, both real):
- execute-phase.md step 5.75: this change is what first activates
  kind == "step" dispatch at execute:wave:post, which newly opens the
  ref.command shell path at that loop point. Our own step uses ref.agent
  and never touches it, but the door is now open, so the step-dispatch
  line carries the same in-context validate-before-shell warning the
  sibling gate-dispatch line directly below it already carries.
- gsd-dom-verifier: quoted page text in DOM-VERIFY.md is attacker
  influenced. Require it wrapped in inline code or a fence, kept short,
  and never left reading as a directive to the next reader.

Verified on the remote runner.

Refs #2856

* fix(#2856): settle the new-agent roster ripple

Checkpoint 2 returned 28 failures, none in the new suite — all of them
the guards that exist to make adding an agent a deliberate act. Each is
a real boundary that had to move:

- docs/AGENTS.md: Tools row must copy the frontmatter verbatim (#2526),
  so the browser globs lose their backticks; primary-agent counts 21->22,
  roster 33/34->34/35, Verifiers category 1->2
- docs/INVENTORY.md: roster completeness requires every agents/gsd-*.md
  to be classified exactly once
- gsd-dom-verifier: add the anti-heredoc instruction and the commented
  hooks: frontmatter pattern both agent gates require
- gsd-core/bin/shared/model-catalog.json: every shipped agent needs a
  profile entry (#3229)
- copilot-install / kilo-upgrades / qwen-upgrades: expected agent list
  and the 34->35 roster boundary
- execute-wave-post-gate-pipeline-e2e: execute:wave:post legitimately
  carries one step now. Asserted as an exact shape — one step, capId
  live-dom-uat, ref.agent gsd-dom-verifier, onError skip — so it stays a
  real guard against accidental change rather than being relaxed

Two findings worth naming:

mcp-tool-inheritance (#2526) rejected the agent for documenting
mcp__playwright__* while its tools: line withholds it — a dead
instruction that invites the agent to claim a path it cannot take. The
prose now names the Playwright MCP family without the dispatchable
token, in both the agent and the capability fragment.

runtime-launcher-parity rejected the new gsd_run call: each fenced block
is its own shell, so a workflow step file invoking gsd_run needs its own
canonical preamble. Propagated with scripts/sync-runtime-launcher.cjs.
That script also normalizes explore.md, which is unrelated pre-existing
drift the parity check tolerates, so it is reverted to keep this diff
scoped.

The emitted-drift ack supersedes the spent #3370 entry for
execute-phase.md — it is merged into next, so its ripple is absorbed at
the base and it can no longer clear anything. That is the same supersede
the #3370 entry itself performed on the spent #3324 fragment. Its
unrelated execute-plan.md entry is untouched.

Verified on the remote runner.

Refs #2856

* fix(#2856): drop the stale emitted-drift ack entry

The automated-ui-verification.md entry was written speculatively rather
than from a reported growth, and the check names that precisely: an ack
"written or reworded in THIS diff, but nothing here needed it, so it
explains nothing".

The growth tier keys on the bare filename as it appears under
gsd-core/workflows/ or agents/. automated-ui-verification.md is nested
under verify-work/steps/, so it was never in the tracked set — only
execute-phase.md was ever reported, both before and after the launcher
preamble landed.

Only ack what the check actually reports.

Verified on the remote runner.

Refs #2856

* chore(#2856): backfill changeset pr number

pr:0 -> 3716. The placeholder fails both changeset-lint
(fail_invalid_fragment) and docs-lint (fail_malformed_fragment) by
design and can only be resolved once the PR number exists. Both now
report ok against GITHUB_BASE_REF=next.

8da2dd3ad2 feat(#2790): add read-only planning.inspect schema-v1 snapshot query (#3708)
* feat(#2790): add read-only planning.inspect schema-v1 snapshot query

Adds a read-only query emitting a schema-versioned JSON projection of .planning/
so downstream harness UIs can consume planning state without parsing GSD's
Markdown a second time.

Composed strictly from the ADR-3180 section 7 owners plus parsePlanDocument,
parseRequirements and parseUatItems; markdown structure is read through the
Markdown Sectionizer and Markdown Table Model seams. It declares its own flat
external schema rather than serializing PlanningSnapshot, which is the
diagnostic-rule subject and still growing.

Extracts plan-document parsing out of cmdPhasePlanIndex into a shared leaf
module so phase.plan-index and planning.inspect cannot drift, including the
plan-id derivation both surfaces report.

Also fixes parseRequirements dropping the separator delimiter used by the
shipped requirements template, surfaced while wiring the requirement rows.

* fix(#2790): close spec gaps and a raw-text test assertion found in review

Review findings from the standards, spec and security passes:

- phases[] rows carry goal and dependencies, the two per-phase elements the
  issue Summary names that had no corresponding field. Goal is bounded to the
  section's leading prose so the Depends-on line, the Plans checklist and the
  wave annotations are not duplicated into it.
- requirement rows carry their own diagnostic codes, so a consumer no longer
  has to string-parse the global diagnostics subject to correlate.
- roadmap_acceptance.checkbox is looked up through the phase-id key owners.
  It was compared raw against the on-disk directory name, so it read null for
  every real-world slugged phase directory and the evidence channel was inert.
- the hostile-input test asserts the structured payload instead of matching the
  raw stdout string. The absence proof over raw stdout is kept deliberately.

* fix(#2790): register planning in the runtime usage list and repair fixtures

Remote runner reported 9 failures on 9b3f9aa. Two root causes, both fixed:

- gsd-tools.cjs registered the planning family in HOST_COMMAND_ROUTERS but
  never added it to TOP_LEVEL_USAGE's Commands list. Those are two surfaces a
  parity test guards, and the top-of-file block comment is not the runtime
  help string. A real wiring gap that every local gate and three review passes
  missed.

- the new suite's fixtures could not produce a resolvable phase set. STATE.md
  frontmatter omitted the milestone field, which ADR-3180 7.2 rule 1 makes the
  primary milestone selector, so the phase set scoped unscoped and every
  percentage was correctly withheld. Separately declarePhase returned a path
  without creating the directory, so a phase declared but never written to left
  phases empty. Both reproduced against the built module before fixing.

No assertion was weakened. The withholding path is still exercised and still
returns null when the roadmap is absent.

* chore(#2790): backfill changeset pr number

* test(#2790): cover every enumerated matrix row and contain a symlink escape

Reverses a silent deferral. An earlier revision left 23 of the 78 enumerated
matrix rows unimplemented and 7 more as one-off manual checks, with a paragraph
in the artifact and the PR body describing the gap. CLAUDE.md is explicit that
such a note is not a fix and is not surfacing. The rows are implemented instead
and the manual-evidence bucket is gone: 49 test cases become 88, covering all 78.

Writing the symlink row proved a real leak: a *-PLAN.md symlinked outside
.planning/ had its content emitted into the payload, confirmed via a direct call
and the spawned CLI. readDocument now resolves target and planning root with
realpathSync and rejects an escape, returning the ordinary unreadable-document
shape. Tested both ways, because a containment check that over-rejects is its own
defect: an escaping symlink leaks nothing and degrades that plan alone, while a
legitimately relocated .planning/ symlink stays fully readable.

The three new modules are registered in the mutation COVERED registry, which had
been reporting has_work false and skipping the Stryker gate entirely. Provisional
non-binding floors so the shards run and report; raised to the measured value
before merge, since the registry forbids calibrating from a local run.

* fix(#2790): satisfy the mutation ratchet contract and scope the 1MB test

Remote runner reported 16 failures on 8c451ed. Two causes.

The COVERED registry has a paired contract the earlier commit violated: every
module needs a matching RATCHET_BASELINE entry, and minScore must be between 50
and 100 with minScore === baseline. The provisional floor of 1 was illegal on
both counts. All three modules now sit at 50 — the registry's own enforced
minimum — with matching baselines. The score cannot be measured locally: the
shard runs node --test, which this repo hard-blocks, so CI is the only source.
Floors are raised to the measured value once this PR's shards report; a shard
below 50 means the tests need strengthening, since the floor cannot go lower.

The 1MB test was measuring the test harness rather than the product. The command
handles the oversized payload correctly by spilling to a tmpfile and resolving it
back, but the resolved stdout then exceeds runGsdTools' maxBuffer and the helper
reports ENOBUFS. It now uses --pick so stdout stays one byte while the full 1MB
document is still read and parsed end to end.

* fix(#2790): wire containment across every document read this command drives

An isolated security review of the containment control found the boundary logic
sound but not comprehensively wired: two content reads reached the filesystem
without it.

An escaped phase DIRECTORY could enumerate external filenames into the file
fields and diagnostic subjects. Both enumeration sites now containment-check the
directory before reading. Worth recording that the leak was already prevented one
layer earlier than the review claimed: Dirent#isDirectory() reports false for a
directory symlink, so such a directory never becomes a phase row at all. The
guard is defense-in-depth for a direct caller and for platforms where a reparse
point reports as a directory.

A *-VERIFICATION.md symlinked outside the root leaked one frontmatter value
verbatim, because readVerificationStatus does its own read and copies an
unrecognized status into the payload's next_action. Closed from the consumer
side through that function's existing fs injection seam, so src/verification.cts
keeps its signature and its other callers are untouched.

The reviewer additionally rated a forged status: passed as an integrity bypass.
It is not: anyone able to plant the symlink can plant a real VERIFICATION.md
saying the same thing. The incremental risk is confidentiality, which is what
these fixes close.

src/plan-scan.cts is deliberately unchanged: isPlanSuperseded reads
symlink-followed content but yields only a derived boolean, no document text.

* test(#2790): give the mutation shards an in-process surface

Two Stryker shards were CANCELLED at the 15-minute cap, not failed on score.
CI log: 640 mutants instrumented, and the dry run reported 'Ran 1 tests in 20
seconds' because the shards pointed at the integration suite, where nearly every
case spawns a gsd-tools subprocess and Stryker's command runner treats the whole
test-runner invocation as a single test. 640 x 20s cannot finish in 15 minutes;
at the kill it was 27/640 with an ETA over an hour.

Every other COVERED module points at a property or unit file, and the workflow's
own paths filter lists exactly those two patterns. In-process is the intended
mutation surface; the shards were pointed at the wrong shape of test.

Adds tests/planning-inspect.unit.test.cjs — 39 cases in 10 describes that spawn
nothing and call the built modules directly. plan-document and the router need no
filesystem at all, one being a pure content-to-object parser and the other taking
an injected mock. The three shards now point here. The 91-case integration suite
is untouched and still runs in the normal test job.

* chore(#2790): ratchet mutation floors to the measured CI scores

CI run 32392791843 measured all three shards, which is the only source the
registry accepts — local runs count timeouts as kills and inflate badly.

  planning-command-router  95.65 -> floor 94
  plan-document            76.58 -> floor 75
  planning-inspect         57.03 -> floor 56

Applied the registry's own rule, floor(score) - 1, and updated RATCHET_BASELINE
to match, since the ratchet test enforces equality.

planning-inspect sits well below the file's target of 80 and is the obvious
ratchet candidate as its tests improve. planning-command-router already exceeds
the target. The placeholder comment about floors pending measurement is removed
rather than left standing as a false statement.

2fca0e17e4 enhance(#2554): resolve code review depth from path-scoped override rules (#3695)
* test(#2554): failing-first suite for path-scoped code review depth overrides

Binds the not-yet-built code-review-depth module: segment-aware path-prefix
matching of a changed-file set against ordered {paths,depth} rules, resolution
order flag > strongest matching rule > global > standard, typed validation
errors, and the large-scope downgrade boundary. Also proves behaviorally that
workflow.code_review_depth_overrides is not yet a registered config key.

Refs #2554

* feat(#2554): resolve code review depth from path-scoped override rules

Adds workflow.code_review_depth_overrides — an ordered array of {paths, depth}
rules matched against a review's changed-file set by segment-aware path-prefix
comparison. Resolution order is --depth= flag, then the strongest matching rule,
then workflow.code_review_depth, then standard; a matching rule replaces the
global rather than being max'd with it, so quick and standard rules stay
meaningful. Glob metacharacters are a hard configuration error rather than sugar
for a prefix, and malformed rules halt the review instead of degrading to
standard. The resolver is pure and reports its own provenance, so the workflow
can print the resolved depth and the rule that matched. The pre-existing
>50-file deep-to-standard downgrade moves into the module and now names the rule
it overrode.

The key is registered centrally rather than as a capability config slice: the
federated slice channel admits only boolean/string/number/enum, so an array
slice would be dropped as malformed.

Closes #2554

* test(#2554): correct depth-provenance assertions and pin out-of-repo paths

Two corrections to the failing-first suite. The source assertion for a
non-matching rule with no global configured expected 'config'; with no global
set the depth comes from the default, and a companion assertion tolerated
either value, so both passed against an implementation that derived provenance
from whether any rules existed rather than from where the depth came from.

The out-of-repo absolute-path case used a home-directory path that matched
neither implementation, so it never exercised the defect it named. It now pins
the discriminating cases: an absolute path outside the repo root must not match
a repo-relative rule, and one under the root must.

* docs(#2554): document path-scoped code review depth overrides

Reference rows for workflow.code_review_depth_overrides in the configuration,
features and commands references plus the locale copies that carry those tables,
and in the planning-config reference. Explanation of why escalation is
whole-review rather than per-file and why v1 is prefix-only. New how-to for
scoping review depth by path, carrying the configuration-error reason table and
the distinction between nothing to report and could not look. CONTEXT.md
glossary entry and the INVENTORY row for the new CLI module.

ja-JP and ko-KR CONFIGURATION.md carry no code_review keys at all, and ko-KR and
pt-BR FEATURES.md carry no code-review config table, so those files are
deliberately untouched.

* fix(#2554): make the depth-misconfiguration halt executable and reject control chars

Three review findings, all in this change.

The misconfiguration halt was prose rather than shell: the error-printing fence
was followed by an unconditional extraction fence, so an ok:false result threw
and left the depth empty instead of stopping the review. Prose is not a guard —
the two fences are now one block with a real conditional, and anything that is
not the literal string true fails closed.

An interior control character in a rule path survived validation and reached the
provenance string and the summary box; rule paths now reject control characters
via a new PATH_CONTROL_CHAR reason, after the glob check so precedence is
unchanged. That in turn makes the field record safe to delimit, so the seven
node invocations that each re-parsed the same result to read one field collapse
to one.

Also corrects the glossary entry's illustrative paths, which the glossary-ref
check read as real repository references.

* fix(#2554): use the fast-check v4 string API and acknowledge workflow growth

Two failures from the remote matrix on d3111f45, both this branch's.

The property block built its segment arbitrary with fc.stringOf, removed in
fast-check v4. Because the arbitrary is constructed in the describe body, the
throw took out all four property tests rather than one — they had never
executed. Rewritten to fc.string({unit, ...}), the form this repo already uses
in emitted-attribution.test.cjs. Every other fast-check helper in the file was
audited against the installed module.

The emitted-attribution growth arm needed an acknowledgment for code-review.md,
which grew 5376 bytes. The pre-existing 3503 fragment keying the same file is
spent — its ripple was absorbed when #3503 merged, and the base file is exactly
the 34435-byte baseline this growth is measured against — so it cannot clear
anything, while the ack lint hard-fails on a duplicate key across two sources.
Removed it in favor of the new fragment, which is exactly how #3503 itself
replaced the spent 3191 fragment.

79781e68eb enhance(#2401): ground verify-command paths and inherit prior-phase commands (#3678)
* feat(#2401): ground <automated> verify-command paths and inherit prior-phase commands

Adds a deterministic resolvability probe over each PLAN.md <automated> verify
command and surfaces the nearest prior phase's proven commands to the planner
at every context window.

- src/verify-command-grounding.cts: recognizer (not a shell interpreter) that
  grounds a leading cd <literal> chain and npm --prefix <literal>, and reports
  unresolvable rather than guessing. Never executes command text.
- gsd-tools check verify-command-paths <N>: per-phase probe, wired into
  plan-phase.md before the plan-check pass.
- init.plan-phase gains prior_verify_commands, ungated by context_window.
- gsd-plan-checker: new Verify Command Path Resolvability dimension that
  reports the failing target and never prescribes a replacement.

Also fixes first-match-wins prefix bucketing in scripts/lint-test-file-count.cjs
(readdir order is not stable across platforms, so a module whose name extends
another's with a hyphen bucketed differently on Linux than on macOS).

Closes #2401

* fix(#2401): ground the canonical --prefix form, quoted paths, and absolute cd resets

Independent review found three defects in the recognizer:

- npm --prefix DIR run SCRIPT never reached the script-existence check,
  because the pattern required npm and run to be adjacent. That is the
  form the docs tell planners to prefer, so script_missing never fired
  for it. The prefix flag and its value are now stripped before matching.
- --prefix captured with \S+, so a quoted path containing a space was
  truncated to a stray opening quote and reported as a missing directory
  - a false blocker, worse than the bug this feature fixes. The capture
  is now quote-aware.
- A chained cd whose later segment was absolute concatenated instead of
  resetting, producing a nonsense path and another false blocker. The
  fold now resets on an absolute segment.

Also replaces the bespoke phase-directory regex with the canonical
phase-id helpers. Real phase directories are NN-slug, not phase-N-slug,
so the prior-command harvest matched nothing outside its own fixtures
and the planner-inheritance half of this feature was dead code.

* refactor(#2401): source task blocks from the canonical sectionizer

The module carried its own copy of the <task>-block grammar - a fourth
hand-rolled mirror of the one markdown-sectionizer owns. verify.cts keeps
its copy only because it needs the type= attribute the canonical helper
discards; this module never reads that attribute, so it can share the
owner outright instead of adding a test around a copy.

extractAutomatedCommands now takes task bodies from extractTaggedBlocks
and the out-of-task remainder from stripTaggedBlocks. A task-grammar
parity test pins the attributed task-name set against the canonical
helper across six awkward task shapes.

* fix(#2401): extract agent-file overflow to references and repair the property arbitrary

The remote matrix run came back red with 19 failures, four root causes:

- agents/gsd-plan-checker.md and agents/gsd-planner.md both blew the
  49152 agent cap. Their bodies move to gsd-core/references/, leaving
  @-reference stubs, per the documented overflow pattern.
- The new checker dimension invoked gsd_run before the canonical
  preamble that defines it. The call is deleted outright: plan-phase.md
  already runs the probe and hands the result in as {VERIFY_PATHS}, so
  the dimension consumes that rather than re-running anything.
- fc.fullUnicodeString does not exist in fast-check 4.8.0. Replaced with
  fc.string({ unit: 'binary' }), which covers the same 0000-10FFFF range.
- Three runtime-loaded files grew; acknowledged in the existing ack
  fragments that already own those bare filenames, since two ack sources
  may never name the same path.

* test(#2401): regenerate golden install-tree fixtures for the new references

Adding two files under gsd-core/references/ changes what the installer

fixtures went stale. Regenerated with npm run gen:install-tree; the
delta is exactly the two new reference paths per runtime, no removals.

* chore(#2401): backfill changeset pr number to 3678

* fix(#2401): treat ~ as a home expansion only at the start of a path

Windows CI caught this on both shards; the Linux-only remote matrix
cannot see it. The dynamic-path refusal rejected ~ anywhere, and a
GitHub Windows runner's tmpdir is an 8.3 short name -
C:\Users\RUNNER~1\AppData\Local\Temp - so a valid absolute Windows
path came back unresolvable/dynamic_path.

This was a production bug, not a test artifact: any Windows user whose
project path carries an 8.3 short name, or any literal ~, silently lost
the probe entirely - every command degrading to unresolvable with no
explanation.

~ is a home expansion only at the start of a path; elsewhere it is an
ordinary literal. The check is now split: $, backtick, *, ? and newline
stay refused anywhere (substitution and globs, and the glob characters
are illegal in Windows path components regardless), while ~ is refused
only leading, tolerating one leading quote since the check runs before
quote stripping.

The prior tests only caught this on Windows because only Windows puts a
~ in tmpdir. Four new tests pin it on every platform via a fixture
directory literally named RUNNER~1.

1adf6d2245 fix(#3620): point the docs at files that actually exist (#3658)
* fix(3620): point the docs at files that actually exist

docproof found 34 stale references; the reporter hand-read all 34 and reported the 8 that
are real, explaining why the other 26 are deliberate (files the documents themselves label
legacy or "superseded by", and one pre-Diataxis link label whose target still resolves).
Those 26 are left alone — re-touching them would contradict the issue's own analysis.

Every claim was re-verified against git ls-files at HEAD before editing.

docs/INVENTORY.md said its roster is anchored by six drift-control tests. Five are gone
(commands-doc-parity, agents-doc-parity, cli-modules-doc-parity, hooks-doc-parity in
5d8a8c4d; command-count-sync in fbf30792), so the sentence now names the one that exists.
Whether one test is sufficient coverage is a maintainer question the issue explicitly
declined to answer, so no new drift tests are proposed here.

The four translations were a revision further behind, each naming a seventh test deleted in
ae8bb707 that the English file had already dropped. All four now match.

Renamed targets corrected in CONTEXT.md, VERSIONING.md, docs/CONFIGURATION.md and the
update workflow. The new test names carry no issue-NNN- prefix, which is what
lint-regression-test-names requires, so they are the correct targets.

docs/TESTING-SUITES.md is the one that could cost somebody time: it INSTRUCTED contributors
to add an acknowledgment to the legacy drift-ack file, which CONTRIBUTING.md says to never
use. Rewritten from the real workflow — per-PR fragments under the drift-acks directory,
and a spent base-side ack is re-armed by rewording that fragment's reason in place, never
by adding a duplicate, since two sources naming one path is a hard error.

docs/skills/discovery-contract.md's heading named a query module deleted in 11918dcc. The
section was REMOVED rather than retargeted: its documented behavior (skip the deprecated
root) is not what the surviving code does — skill-manifest includes that root marked
deprecated:true — so retargeting would have documented something false.

Found and fixed inline, same class: VERSIONING.md described an SDK bundling step the
release workflow does not have (zero such mentions in that file); CONFIGURATION.md and four
translations named a dead model-catalog triple collapsed by ADR-457.

Dead config removed: the changeset lint's user-facing prefix list still carried two retired
sdk entries. git ls-files -- 'sdk/*' returns nothing. No test pins that array.

Left deliberately: the comment explaining the retired catalog path, the install regression
test that reconstructs the old broken layout to prove it fails, and the generated
test-timings cache. Each is a legitimate mention of a dead path, not drift.

Note lint-removed-but-needed cannot catch this class: it diffs baseRef...HEAD, so it only
sees files deleted in the change under review. These were orphaned by PRs that predate the
lint. A repo-wide existence audit would need a suppression mechanism for the 26 deliberate
mentions above; that is a feature, not part of this fix.

ac1b6d679f enhance(#3618): fold fallow-runner onto the canonical binary resolver (epic #3411 Phase 2) (#3633)
* chore(#3618): fold fallow-runner onto the canonical binary resolver

Epic #3411 Phase 2. src/fallow-runner.cts was the fourth divergent
implementation of Windows binary resolution the epic enumerated —
candidateNames, isExecutableFile, findInPath, findInNodeModules, 40 lines.
All four are deleted; resolveFallowBinary is one seam call.

Two OPT-IN options were added to resolveExecutableBinary to make the fold
behavior-preserving, both defaulting off so Phase 1's callers are byte-identical:

  prependPaths      dirs searched before env.PATH, in order, through the
                    identical per-directory candidate logic. This expresses
                    node_modules/.bin-first precedence without env surgery —
                    the rejected alternative re-introduced the
                    spread-loses-the-proxy hazard the Windows lane caught in
                    Phase 1, at every future call site instead of once.
  requireExecutable POSIX-only accessSync(X_OK); a no-op on win32 where mode
                    bits do not mean execute. Opt-in rather than default
                    because unconditional X_OK breaks #3445's suite, which
                    stages candidates with plain writeFileSync and never sets
                    an exec bit — the repo bans chmod in tests — so every one
                    would resolve to null on POSIX.

Deliberate behavior change on Windows: fallow's prior candidate list ended in a
BARE fallow. The seam never tries a bare name there, so an extensionless file
beside fallow.cmd is no longer resolved. That is the fix, not a regression — the
extensionless file is npm's POSIX sh shim, which CreateProcess cannot run
(#3275). Rows 7 and 8 of the design record it.

Defect found while working, fixed inline: the resolution order was documented
BACKWARDS as PATH-then-.bin in structural-pre-pass.md, docs/INVENTORY.md and
four INVENTORY translations. The code has always been .bin first, and .bin first
is correct — a project-local tool should beat a global one. The archived
changeset is left alone as a historical record.

fallow-runner had no test file at all. tests/fallow-runner.test.cjs is new
(F1-F15) and the seam options are pinned by S1-S12 folded into the existing
dispatch suite. RED proven by execution: with both source files stashed and
build:lib re-run, 7 of 27 probe cases failed.

Refs #3411

* chore(#3618): backfill changeset pr number 3633

* fix(#3618): assert both platform contracts in F4 instead of a POSIX-only premise

Windows CI on #3633 failed F4. The test monkeypatched accessSync to throw and
asserted resolveFallowBinary returned null — but that premise, that the X_OK
check is consulted at all, is POSIX-only by design. requireExecutable is a
deliberate no-op on win32 because Windows mode bits do not mean execute, so the
staged fixture correctly resolved there.

40-design.md's negative-space section already states this carve-out verbatim.
The test contradicted the design it was written from: fixtures were made
platform-adaptive in the previous commit, and this assertion was left
platform-blind.

F4 now asserts BOTH contracts — null on POSIX, resolves on win32 — rather than
skipping either. A t.skip on one lane would have been green and would have left
the win32 carve-out unpinned by fallow's own entry point.

Audited every other row for the same class. F1-F3, F5, F6, F11-F15 hold on both
platforms; F7-F10 and S1-S12 inject platform explicitly and are unaffected. F4
was the only row with a single-platform premise.

The local probe runs on one platform and structurally cannot catch this, which
is why it was green — that limitation is now stated at the top of the probe so a
green probe is not mistaken for platform coverage. The win32 branch was proven
by injecting platform:'win32' with accessSync throwing and asserting it still
resolves.

3ab0007164 enh(#2875): materialization primitives — durable user-artifact staging and descriptor-authoritative agents (#3600)
* fix(#2875): stage user artifacts durably across install wipes (#1874-F19)

preserveUserArtifacts held user files only in an in-memory Map across the
wipe, so any process death between preserve and restore lost them outright.

Seven call sites, not the four the issue records. Three of them never called
the helper at all - they open-coded the same read/wipe/write - so searching
for callers under-counted by construction; the extra sites were found by
sweeping for the pattern instead.

The worst is the mainline install path, where the crash window spans the
entire gsd-core tree copy rather than a single rmSync.

Adds src/user-artifact-staging.cts: durable on-disk staging with a record
written after the copies land as the commit point, plus recovery of orphaned
batches on the next run - without recovery the staged bytes survive but the
user's file is still gone, which would pass its own test while delivering
nothing.

Routes copyPreservingSymlink through installFs() so staging cannot bypass the
install fs seam, and reunites its symlink-safety docblock with the function it
documents.

* docs(#2875): amend ADR-3574 with four claims disproved by implementation

Implementing Phase 6 disproved four statements the ADR rests on. The central
decision - no single materializer - is unaffected and stands.

Corrected: decision 3 was already satisfied, so nothing was extracted; the
agents-bypass runtime set omitted claude, kilo and opencode, and closing it
needed three new pieces of descriptor contract rather than proceeding on its
own terms; three of the four blockers the layout comment names were already
stale; and F19 is seven call sites, not four.

Records the generalizable lesson: the defect is the pattern of holding user
data in memory across a wipe, not the helper, so searching for callers of the
helper under-counts by construction.

Also resolves the ADR's open question on USER_OWNED_ARTIFACTS membership, and
notes that copyPreservingSymlink needed routing through the install fs seam
before it could be reused.

* fix(#2875): close dangling-symlink blind spot and harden staging recovery

An adversarial review found the F19 staging work shipped red and unsafe.

Root cause, shared by two arbitrary-write findings: hasExistingSymlinkBetween
missed dangling symlinks in both its root check and its per-segment walk,
because it probed with existsSync, which is false for a link whose target does
not exist. Fixing only the new module would have reused a guard that was
itself blind. This guard protects the whole install tree.

Recovery no longer throws: it degrades per entry and per file, so one bad
batch cannot block the others. Previously an unrecoverable entry propagated
out of the first statement of install and uninstall, before the cleanup that
would have removed it - wedging the installer permanently.

Partial fs adapters now throw on any omitted method instead of silently
reaching the real filesystem, closing the trap that let a test poison list
pass while real IO happened.

Staged names must be flat, recovery refuses a dangling destination symlink,
and a batch whose recovery genuinely failed is no longer swept - it was
discarding the only durable copy of the file it had just failed to restore.

Replaces three tests that could not fail, including the one labelled negative
proof.

Known limitation, documented not closed: concurrent installs sharing a staging
key can still lose a batch. A real fix needs a cross-process lock.

* enh(#2875): make the descriptor authoritative for the agents kind

Deletes the inline agent-staging loop in bin/install.js and the
_DESCRIPTOR_AGENTS_RUNTIMES set, so every runtime materializes agents from
its capability descriptor instead of an inline hostBehaviors dispatch.

Closing it needed three pieces of contract the descriptor pipeline never had,
all reducible to one missing input - per-agent resolution context: a
frontmatter-extensions step for claude's effort and disallowedTools, per-agent
model-override resolution for kilo and opencode, and a named branding
converter for hermes, whose rewrite data was already declared.

Seven runtimes were on the loop, not the six the design recorded - kimi-code
was found by a golden fixture, not by analysis. claude-local and kimi-code
both silently lost their agents mid-change; the fixtures caught both and the
cause was fixed rather than the fixtures regenerated.

A parity harness gates the migration: both pipelines over identical inputs,
byte-identical output including filenames, per runtime. It is demonstrated
red before being trusted. Surface and install paths converge for all seven,
which also fixes surface previously writing no agents for these runtimes.

Codex's config.toml strip stays put - it mutates host config, which no
descriptor kind models.

Also routes install-model-override-resolver and install-effort-resolver
through the install fs seam. Both leaked real filesystem IO from the install
call tree; the stricter adapter is what exposed them.

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

* docs(#2875): record the agents-descriptor migration and correct the ADR count

The _DESCRIPTOR_AGENTS_RUNTIMES allow-list no longer exists, so the host
integration guide told readers to join a set that is gone. Replaces that with
what is now true - declare an agents entry and it installs, on the surface
path as well as install - and points anyone needing a per-agent transform at
the three extension points rather than at a new inline branch.

Corrects the ADR amendment: seven runtimes were on the inline loop, not six.
kimi-code was found by a golden fixture going red, not by reading. That is the
third short count this phase, all from enumerating by symbol or set membership
when the thing that matters is a behavior.

Adds the Changed changeset for the surface-path convergence.

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

* docs(#2875): amend ADR-2866 - claude global always wrote agents on disk

The claude row's global=[skills] described what capability.json declared, not
what the installer wrote. bin/install.js's inline agent-staging loop was never
scope-gated and never consulted the descriptor, so a claude --global install
has always written agents/gsd-*.md.

Phase 6 closes the gap by deleting that loop and declaring agents on claude's
descriptor at global scope. On-disk bytes are unchanged - the golden fixtures
did not move, which is the evidence that the descriptor, not the installer,
was incomplete.

#2218 is unaffected: agents are not trigger-bearing, so the wider row does not
introduce a new shadowing case.

Records the warning that an incomplete descriptor is invisible while a second
code path silently does its work, and only surfaces when the two are forced
into agreement.

* fix(#2875): close review findings across staging, agents and the parity harness

Two independent reviews of this branch found defects the local gates missed.

Security: a dangling symlink at a migration destination allowed writing
outside configDir - the same class this change claimed to close, missed at the
terminal write of the flow being added. The staging-root resolver threw as the
first statement of install and uninstall, so a hostile symlink bricked both,
and symlinked-configDir users lost uninstall as well as install; it now
degrades instead of aborting. Recovery gained a source-side symlink check and
now refuses a relative destDir, which resolved against cwd. Converter dispatch
gained a runtime allowlist - lint-time validation stopped mattering once this
branch promoted that dispatch from the surface path to real installs.

Correctness: claude --local --minimal exited 1 because the minimal profile
legitimately yields zero agents and the new path treated that as a failure.
cline --local silently lost its agents - its descriptor declared none while
the deleted loop wrote them unconditionally. The agents prune was widened to
any gsd-* entry and destroyed user files it never owned.

The parity harness, on which the migration's safety argument rested, drove a
synthetic registry and never byte-compared the shipped descriptors; two of its
trap rows could not fail. It now drives the real registry across 13
runtime-scope rows including kimi-code and cline-local, and its red-proof is
demonstrated by corrupting a live capability.json. Three goldens that had
encoded the cline regression as expected behavior were corrected.

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

* fix(#2875): close findings from both mandated review engines

/security-review found the staging source-side walk honouring
GSD_ALLOW_SYMLINKED_DEST, an opt-in documented as relaxing only the write
destination. A symlinked files/ component dereferenced because
copyPreservingSymlink lstats the leaf only, so an intermediate link is
followed. The source walk no longer honours the opt-in; the destination check
still does.

/code-review spec axis found this branch had reintroduced its own bug:
migrateLegacyDevPreferencesToSkill's new symlink refusal threw unguarded after
the legacy dir was wiped and before the staged batch was restored, so a
planted symlink bricked uninstall permanently and orphaned the batch. Refusal
kept, abort removed.

kimi-code local silently lost its agents, the same class as the cline bug, and
the parity harness recorded that exclusion as intentional - the third test in
this branch to pin a regression as correct.

--minimal now creates an empty agents/ dir that never existed. Behaviour
restored rather than softening the changeset, so its byte-identical claim
stays true.

Standards axis: try/finally removed from twelve test bodies, fast-check
properties added for parseOwnerPid, boundary coverage at the grace window and
the ancestor-probe depth, a parity assertion for the staging-root helper
duplicated across two files, and the 8-deep config walk deduplicated.

Records 60-review.json with every finding and disposition from five passes,
including the smells left unfixed and why.

* fix(#2875): prune stale agents unconditionally in minimal mode

The previous round stopped an empty agents/ directory being created when the
resolved profile yields no agents. That was implemented by skipping the agents
kind entirely, which also skipped its stale-agent prune - so a full to minimal
downgrade left stale gsd-* agents behind.

The deleted inline loop pruned unconditionally and only skipped writing. Those
are three separate conditions, not one: prune always, write only when there is
something to write, create the directory only when writing.

Both call sites now run _removeGsdEntries before the empty-staged early exit.
The symlink-escape guard moved with it, since the prune also touches dest.
Codex .toml agents and the config.toml stanzas are cleaned again, and
user-owned agents are still preserved.

The agents/ directory is left in place after a prune empties it, matching
every sibling kind - none of them remove the destination directory itself.

Golden fixtures confirmed byte-identical: the prune is a no-op on a fresh
install, so fixture generation is unaffected.

* docs(#2875): document interrupted-install recovery for user-owned files

The durable-staging fix is invisible to the user it protects. Someone whose
install died mid-flight has no way to know USER-PROFILE.md was staged before
the delete, that the next run restores it, or that recovery happens at the
start of that run rather than in the background.

Written as the task the user has - finish the interrupted command - rather
than as a description of the mechanism, and states what it will not do:
overwrite a file already present, or touch staging belonging to another
install still running.

* test(#2875): assert the J8 model override without building a regex

CodeQL flagged incomplete string escaping: the assertion interpolated the
override value into a RegExp while escaping only forward slashes, which is
meaningless in a constructor, leaving real metacharacters unescaped.

The failure direction was the dangerous one - a metacharacter would have made
the match more permissive, so the row would pass when it should fail. That
matters here because J8 exists precisely because an earlier revision was a
tautology; the rewrite reintroduced a different way for the same assertion to
stop discriminating.

Replaced with a line-wise exact match, so no regex is constructed at all.
Swept the other test files this branch adds; no sibling instances.

lint:ci passed on the original - lint-no-adhoc-regex-escape matches a full
metachar-escape copy, so a single slash replace slipped under it.

a4a02a7a01 enhance(#2874): return the executed plan and route install IO through a seam (#3568)
* test(#2874): add failing-first gate for the executed-plan return

Four rows from the matrix's red-first order. E3 pins the one early return,
for the opencode family, where a void-shaped hole would otherwise survive
unnoticed. E13 sweeps every runtime in the registry - enumerated from the
registry rather than hardcoded, so a runtime added later cannot slip past.
F2 proves absence of real filesystem contact rather than merely that the
happy path ran, which is the difference between a complete seam and a
partial one.

G1 and G3 are the additive guard and must be green before and after. G3
deliberately leaves the two existing adapter test doubles untouched: if
this change required editing them it would not be additive, and the
acceptance criterion would be unmet.

No production code. All 19 runtimes install without throwing today, so
E3 and E13 fail on the undefined comparison alone.

Refs #2874

* feat(#2874): return the executed plan and route install IO through a seam

installRuntimeArtifacts returned void, so its correctness was observable
only by re-reading disk. It now returns what it executed - per kind, per
scope - including on the combinedFamilyInstall path, which was the one
early return where a void-shaped hole would have survived unnoticed.

Failure still throws rather than becoming an ok:false return, so control
flow is unchanged for both existing callers. A best-effort cleanup that
fails is still swallowed, but is now visible in the returned value rather
than silently absent.

The fs seam is ambient rather than threaded. Explicit deps through
install-profiles and the 3000-line conversion module was impractical; the
tradeoff, the synchronous-only re-entrancy assumption, the restore
guarantee and the partial-adapter fallback trap are all documented at the
seam. findInstallSourceRoot and its sibling stay unrouted by design -
they locate the package's own source, not the install destination.

readCmdNames keeps a second implementation because the standalone CLI
that owns the original cannot require the compiled adapter without a
build-order dependency on its own output. A parity test fails if the two
ever disagree.

Refs #2874

* chore(#2874): gitignore the new build artifact

install-fs-adapter.cjs is tsc output from src/install-fs-adapter.cts, not
a tracked source file. It was added to eslint's ignore list but not to
.gitignore, so it landed as a tracked file - the third time this step of
the new-.cts ripple has been missed on this epic.

Refs #2874

* fix(#2874): close two seam leaks and correct a false comment

A correctness review found the seam still leaked in two places, both
subtler than the three already closed.

readGsdCommandNames was routed when it should not have been: it reads the
package's own commands directory, which a destination-fake is never
seeded with, so under a fake adapter it returned an empty or wrong roster
instead of failing loudly. It now reads real fs, matching the precedent
already documented for findInstallSourceRoot.

cleanupStagedSkills ran raw rmSync from a process exit handler, which is
real filesystem work deferred past the point where withInstallFs has
restored - the one thing the synchronous-only contract exists to
exclude. Staging now captures the adapter that created each directory and
cleanup replays it, so a real install cleans up exactly as before and a
fake-staged path never reaches the real filesystem.

Also corrected a comment claiming the migration reads were an unrouted,
untested residual gap. They are routed and exercised; a comment
understating the seam is as corrosive as one overstating it in a module
whose trust rests on being honestly documented.

Refs #2874

* test(#2874): migrate the exemplar group and cover the matrix

AC3's exemplar migration lands in place: the qwen install group now
asserts skills and agents destinations from the returned plan in one
deepStrictEqual instead of probing the filesystem for each.

Nine facts the old probes established were enumerated first. Two moved to
the value assertion; seven were retained deliberately - per-file SKILL.md
existence, the VERSION file written outside this function, the manifest
content, and the post-uninstall absence checks all sit outside the plan's
per-kind contract. A migration that quietly asserts less looks like a win
and is a regression, so the enumeration is the guard rather than the
line count.

Also implements the rest of the matrix: the executed-plan shape, adapter
failure modes, the security-boundary rows including a fake that cannot
certify an install the real filesystem would refuse, cleanup visibility,
and two seeded property tests. Only the two external CI gates are left
unticked, because self-certifying them would be a claim rather than a
check.

Refs #2874

* fix(#2874): restore streaming hashes and derive F2 from the boundary rule

The checkpoint found three things reasoning had missed.

sha256File had been converted from raw-fd streaming to a single
readFileSync on the assumption that GSD artifacts are never large. A test
named for exactly that contract already existed and went red. Streaming is
restored, now routed through the adapter, which gains openSync, readSync
and closeSync. The contract was the specification; the assumption was not.

Three existing tests inject faults by monkeypatching real fs. They broke
because mkInstallTempDir stopped calling real mkdtempSync, not because of
any binding subtlety - the real adapter was already late-bound. It now
calls the real function when no fake is injected, so a monkeypatch applied
after import is still seen and the additive contract holds.

F2 poisoned real fs by method, so a deliberately unrouted package-source
read failed a correct design. It now poisons by path: destination IO is
forbidden, package-source IO is allowed and positively asserted. The claim
was always zero real destination IO, and the test now derives from that
rule instead of coincidentally matching it.

Refs #2874

* docs(#2874): add the contributor how-to for plan-based test migration

The phase gate caught a real gap. The docs plan was Reference plus
Explanation only, and every CI check would have passed, because the
docs-required lint only verifies that some file under docs/ moved.

But this phase exists to demonstrate a pattern for follow-on work, and
that work is other contributors migrating probing test groups. The
sequence has two live traps - a partial fake silently falls back to real
fs, and the seam is ambient and synchronous-only - plus one discipline
nobody infers: enumerate the facts before converting, or you assert less
and call it a win.

The page carries the qwen migration's arithmetic, nine facts enumerated
and only two converted, because a reader seeing only the diff would
reasonably conclude the pattern is to replace probes wholesale.

No locale mirrors: none of the four carries any contributor-only how-to,
so a single translated file would manufacture parity rather than provide
it.

Refs #2874

* chore(#2874): backfill changeset pr number

* test(#2874): normalize both sides of the G1 tree comparison

G1 failed on Windows only, deterministically on both shards. The defect
was in the test helper, not production.

_computePathPrefix posix-normalizes the resolved config dir
unconditionally, so on Windows the path embedded in every emitted
SKILL.md body is forward-slash form. hashDirTree stripped against the raw
backslash path from mkdtempSync, so the substring never matched and each
install's unique temp suffix stayed baked into every file - all fifteen
skill bodies hashed differently for two runs that had written identical
bytes.

Both sides are now normalized unconditionally rather than gated on
path.sep, matching the rule this repo already records: backslash paths
arrive on Linux too.

Production code is untouched and was verified correct. Normalizing this
away on the production side would have hidden a real portability bug if
one had existed.

c5b83cb050 chore(#3560): delete two unreachable workflows, gate workflow reachability in lint (#3564)
* chore(#3560): delete two unreachable workflows, gate reachability in lint

discovery-phase.md and plan-milestone-gaps.md shipped to all 19 runtime
install trees with no command, agent, or skill referencing them.
plan-milestone-gaps' command was deleted by #2790 and the workflow was
left behind; discovery-phase's own header claimed a caller in
plan-phase.md's mandatory_discovery step, and that step does not exist —
plan-phase.md contains zero occurrences of "discovery".

docs/INVENTORY.md asserted discovery-phase.md was an alternate entry for
/gsd-new-project. new-project.md never referenced it. The row and the
matching note sentence are removed across all five locales rather than
corrected.

Adds rule 6 to lint-command-contract: every shipped workflow must be
reachable from a loader, walking the transitive closure over the three
reference shapes this repo uses. The closure seeds ONLY from
commands/agents/skills, so a workflow that references only itself and a
pair that reference only each other are both correctly reported rather
than satisfying themselves; a visited set makes reference cycles
terminate. The measure is a mention in a LOADER — docs/ and install-tree
fixtures deliberately do not count, because scan.md proved a file can be
documented and shipped while entirely unreached.

Ships blocking, not report-only: #3561 is in this branch's base, so the
tree reports 0 unreachable from the start.

Closes #3560

* test(#3560): drive rule 6 end-to-end, sweep a stale allowlist, update ADR-0002

Review findings.

Rule 6 had no end-to-end coverage: the tests exercised the pure closure
with in-memory data, so the wiring — file collection, exit code,
diagnostic — was unproven, and #3560's acceptance list explicitly wants
a fixture showing the rule FAILS on a planted orphan. Adds an optional
--root to lint-command-contract (default behavior unchanged) and four
tests driving the real CLI through the process seam against a temp
fixture: clean=0, planted orphan=1, orphan referenced only from docs/=1,
orphan reachable transitively=0. The docs/ case is what pins the
Goodhart defense — a mention outside a loader must not confer
reachability.

Deletes two tests that were byte-identical to a third and could not
assert anything loader-specific, since the closure is source-agnostic by
design; that distinction lives in the lint script's file collection and
is now covered above.

Removes a stale ALLOWLIST entry for discovery-phase.md in
planner-language-regression — the exact sweep-miss class rule 6 exists
to catch, found in the PR that adds the rule.

ADR-0002 described five per-file frontmatter checks; rule 6 is a
repo-level reachability graph, so the Decision section now says so.

Refs #3560

* test(#3560): cut the bug-3298 test pin on the deleted plan-milestone-gaps workflow

The remote runner went red with four failures: tests/phase.test.cjs
asserted the plan-milestone-gaps workflow exists and checked its mkdir
patterns, so deleting the file broke the test that pinned it. This is the
fence the epic describes — the content-sync test IS what keeps an
unreachable file alive — and cutting the coupling is what makes the
deletion safe.

Removes only that arm. The bug-3298 block guards three workflows against
phase-dir prefix drift; the import and add-backlog arms and both shared
mkdir-pattern helpers are untouched.

Worth recording where the sweep failed: my reachability walk covered

covers .github/workflows, gsd-core, docs and package.json. Neither looks
at tests/, so a test-pinned deletion is invisible to both and surfaces
only on the remote runner. The how-to added by this PR names that gap
explicitly so the next deletion searches tests/ by hand.

147856040b fix(#2873): close review findings across fences, sanitizer and docs
Isolated security review found resolveSpecRootReference's fence tracker
toggled on any delimiter, so a backtick fence could be closed by a tilde
one and an include in the gap was rewritten inside a code block. Fixed by
reusing scanFencedBlocks - the canonical engine already behind
stripFencedCode and extractFencedBlock - rather than carrying a fourth
copy of fence detection, which also closes the duplication the standards
review flagged.

sanitizeForRender now strips combining marks and zero-width characters
alongside the ANSI, control and bidi classes it already handled.

Adds the C, E and F matrix rows the spec review found missing, including
installer-level coverage that spawns the real install rather than calling
the report builder. Ships the how-to, the reference and command docs in
five locales, the changeset, the inventory and glossary entries, and
regenerates health.md for the new W028 rule.

895d9df96d fix(#3477): run untrusted key_links patterns on a linear-time engine (#3496)
`cmdVerifyKeyLinks` compiled `must_haves.key_links[].pattern` from plan frontmatter with `new RegExp()` and tested it against whole file contents, so a nested-quantifier pattern such as `(a+)+$` hung `verify-phase` indefinitely (CWE-1333). JavaScript has no regex-execution timeout.

Untrusted patterns now run on RE2 (re2js), whose match time is linear in input length — the class is closed by the engine, not by a heuristic screen. The screen lost in the ADR-0174 consolidation was deliberately NOT restored: it never worked, since `(a|a)*$`, `((a+))+$`, `(a+){2,}$` and `(a{1,3})+$` all evade it. A refused pattern's matcher returns false for every input, so it cannot report a match no matter what the caller does.

The engine is vendored at gsd-core/bin/lib/vendor/re2js.cjs because gsd-core/bin/** is copied into installed trees with no node_modules; runtime dependencies are unchanged. New ESLint rule local/no-external-require-in-bin enforces that invariant, which had been documented in a comment since the #3024/#2071 bug class and enforced nowhere.

Backreferences and look-around are unsupported by RE2 by construction — disclosed in a Changed changeset.

Closes #3477

6b34557ba3 fix(#3311): milestone lock makes parallel-phase state conflicts visible (#3455)
* fix(#3311): milestone lock makes parallel-phase state conflicts visible

Two sessions running different phases in one working tree silently
clobbered STATE.md's single un-scoped ## Current Position slot: byte-level
serialization already existed (STATE.md.lock since #464), but nothing ever
surfaced that two sessions claimed two different phases, and
state.advance-plan — which takes no phase argument — kept advancing whatever
plan the just-clobbered position named.

Adds the maintainer-chosen milestone lock (issue #3311 comment): an advisory
.planning/milestone.lock claim keyed by phase + session id (session identity
via getWorkstreamSessionKey: env-first, then controlling TTY). begin-phase
claims (inside the STATE.md lock), advance-plan detects a claim/position
mismatch and heartbeats a matching claim, phase.complete warns via warnings[]
and releases the claim when the claimed phase completes. Conflicts warn
(stderr + typed milestone_conflict JSON field) instead of blocking, per the
decision's blocking/warning latitude; TTL 4h with heartbeat liveness expires
abandoned claims. milestone.lock is registered in the canonical artifact
registry so validate.health W019 recognizes it.

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

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

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

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

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

parseDecisionLines CRITICAL/164 affected symbols (ADR §6 due diligence).

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

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

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

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

0624c5da6f chore(#3212): src/text-lines.cts is the sole owner of line-terminator handling — Phase 2 (#3420)
* test(#3413): failing-first suite for the line-terminator seam

Phase 2 of epic #3212 (ADR-3212 §3/§6/§7). Tests only — src/text-lines.cts
does not exist yet, so tests/text-lines.test.cjs fails with MODULE_NOT_FOUND
at its require line, which is the intended RED.

The frontmatter.test.cjs additions drive #3360 (confirmed-bug) fail-first:
parseMustHavesBlock currently returns [] for every must_haves block on a
CRLF-authored plan file, because \r is its own LineTerminator in ECMAScript
and two /m-anchored \s* patterns can absorb it, inflating a captured indent
by one character and tripping the "not nested under must_haves" guard.
Verified locally against the current (unfixed) compiled module: both the
direct repro and the silent-exit "blank line before must_haves:" variant
return [] today. A parity property test (crlf vs lf must deep-equal for
every block name) matches a pattern this maintainer has required repeatedly
for prior CRLF fixes in this codebase (Cortex-recorded, verify_intent=held).

The no-crlf-fragile-split.rule.test.cjs additions lock the eslint rule's
future fix-hint text (pointing at splitLines()) and its self-reference
non-violation (the seam's own correct \r?\n split must never flag itself).

Design: .gsd/phase/chore-3413-text-lines-seam/40-design.md
Test matrix: .gsd/phase/chore-3413-text-lines-seam/50-test-matrix.md

* chore(#3413): src/text-lines.cts owns line-terminator handling

Phase 2 of epic #3212 (ADR-3212 §3/§6/§7). Adds splitLines/normalizeEol/
detectEol/joinLines and migrates frontmatter.cts onto it.

parseMustHavesBlock (#3360, confirmed-bug) returned [] for every
must_haves block on a CRLF plan file. Root cause: \r is its own
LineTerminator in ECMAScript, so under /m two \s*-anchored indentation
lookups could match at the position INSIDE a \r\n pair and absorb the
terminator, inflating the captured indent by one character and tripping
the "not nested under must_haves" guard. Two silent exits, one with a
diagnostic and one without (a blank line before must_haves: hits the
silent path). Fixed by converting both lookups from a whole-string /m
match to split-then-scan — splitLines first, then a per-line, non-/m
match — the same structural pattern parseYamlRegion (30 lines away in
the same file) already used safely. Nothing downstream of the two
lookups changed; blockLines is now sliced from the already-split array
instead of re-splitting a substring, but its contents are unchanged for
LF input, and the per-line dash/kv parsing loop is untouched.

A parity property test (CRLF and LF plans parse to identical must_haves
for every block name) matches a pattern this maintainer has required
repeatedly for prior CRLF fixes in this file's neighborhood (Cortex:
7 recorded decisions, verify_intent -> held).

frontmatter.cts's other .split(/\r?\n/) call sites (parseYamlRegion,
isFrontmatterShaped, sliceTopLevelFrontmatterSegments, spliceFrontmatter)
are rerouted onto splitLines — a literal 1:1 substitution, zero behavior
change, since splitLines IS that same regex plus a type guard.

The 4 scripts/normalizeLineEndings copies (gen-registry, gen-loop-host-
contract, gen-capability-registry, gen-context-index) are deleted and
rerouted onto normalizeEol, which strips a bare unpaired \r exactly like
the deleted copies did (not just \r\n pairs) -- verified against each
script's own --check mode against its real generated output.

local/no-crlf-fragile-split widens from tests/ to src/**/*.cts, with its
fix-hint message now naming splitLines() instead of the raw regex --
the prohibition finally has a primitive to point at. Detection logic
unchanged in this phase (deliberate scope limit, see design doc Known
limits: the rule doesn't yet recognize safeReadFile/platformReadSync as
a content source, and has no detector for the \s-adjacent-to-anchor
shape that is #3360's actual mechanism -- the CLASS is converged by the
direct fix + regression test regardless).

joinLines/detectEol are NOT wired into frontmatter.cts's own write path
(cmdFrontmatterSet/Merge -> platformWriteSync) -- verified that
platformWriteSync already, unconditionally converts CRLF->LF on every
.md write today as a pre-existing policy owned by a different module,
and ADR-3212's backward-compatibility clause rules out a file-format
change in any phase. Stated explicitly in Known limits rather than left
for a reader to discover.

* fix(#3413): fix 13 pre-existing CRLF-fragile splits the widened rule found

Widening local/no-crlf-fragile-split from tests/ to src/**/*.cts (the
previous commit) immediately surfaced 13 real, pre-existing violations
across 10 files -- undetected until now because the rule never scanned
src/. This is the exact defect class ADR-3212 exists to close, playing
out again one phase after Phase 1 hit the same shape ("the new lint
rule -- once live -- found 27 more"). Per CLAUDE.md's no-defer rule,
fixed inline rather than deferred or suppressed; there is no
established suppression convention for this rule in src/ and inventing
one now would undermine the point of widening it.

audit.cts, broken-windows.cts, core-utils.cts, init.cts, milestone.cts,
phase.cts (x3), profile-output.cts, roadmap.cts (x2): bare-\n splits or
regex character classes widened to \r?\n / [^\r\n], each following the
same pattern already established migrating frontmatter.cts.

phase-estimation.cts: `\r?(?:\n|$)` restructured to `(?:\r?\n|\r?$)` --
already semantically CRLF-safe, but the rule's lexical scanner doesn't
recognize \r? guarding a group (only \r? immediately before a literal
\n). Verified the two forms are equivalent across all four EOL/EOF
cases before restructuring, not assumed.

roadmap-upgrade.cts needed two coupled sites, not the one flagged line:
computeMigrationPlan and applyMigration must agree on line
representation for the lines[edit.lineIndex] === edit.from equality
check to hold, and the write-back needed joinLines + detectEol -- a
plain lines.join('\n') was silently flattening a CRLF ROADMAP.md to LF
wholesale on every migration. This is the first real production
consumer of joinLines/detectEol in this epic (frontmatter.cts's own
write path doesn't use them -- see the previous commit's Known limits).

Fixing the 13 flagged sites surfaced 4 more adjacent same-shape sites
the rule doesn't track (.search() and new RegExp(dynamicString) aren't
in its tracked call/construction set). Investigated each empirically --
hand-tracing this exact bug class already produced one wrong conclusion
earlier in this phase (a detectEol design-doc arithmetic error), so
these were verified with real CRLF fixtures rather than reasoned about
on paper:

  - audit.cts (scanTodos): REAL bug, fixed. `bodyMatch.trim().split
    ('\n')[0]` leaked a trailing \r into a user-visible todo summary on
    CRLF input -- .trim() only strips the string's outer edges, not a
    \r sitting mid-string before the first bare \n. Now splitLines(...)
    [0].
  - phase.cts (cmdPhaseInsert, bullet-style branch): REAL bug, fixed.
    [^\n]* in targetBulletPattern swallowed a line's trailing \r on
    CRLF input, shifting the computed insert position to land INSIDE
    the \r\n pair; combined with a hardcoded '\n' bullet separator, a
    CRLF ROADMAP.md ended up with a mixed CRLF/LF result after an
    insert. Fixed with two coupled changes (either alone still
    corrupts, verified both ways): [^\r\n]* in the pattern, and the new
    bullet's leading terminator now comes from detectEol(rawContent).
  - roadmap.cts (cmdRoadmapAnnotateDependencies phase-boundary scan):
    investigated, genuinely safe, left untouched. The .search(/\n#{2,4}
    .../) boundary-finder and the [^\n]*-based heading match were
    empirically verified on a 3-phase CRLF fixture -- the only stray \r
    ends up at the tail of an intermediate phaseSection string that is
    only ever used for .test()-based idempotency checks, never for an
    exact-match comparison or written back to disk. No corruption on
    round-trip.

Every fix re-verified: npm run build:lib clean, npx eslint
'src/**/*.cts' --no-cache reports 0 problems (was 13), and each
fixed function's existing LF-input tests were spot-checked unchanged.

* fix(#3413): apply orthogonal review findings

Two isolated review engines (correctness + security) ran against the
full diff and found three majors, one real security issue, and several
disclosure-worthy minors. All fixed or explicitly disclosed with
evidence; nothing deferred.

MAJOR — detectEol's tie-break contradicted its own documented contract.
Code returned '\n' on a 1:1 crlf/bare-LF tie; every doc (design doc,
CONTEXT.md, the function's own comment) says ties resolve to '\r\n'.
The existing test masked this by reusing the same tie fixture the
buggy code happened to satisfy, rather than a genuine LF-majority
case. Root cause: an Edit attempted earlier in this phase to fix this
exact arithmetic error was blocked by the tier guard, and a later
dispatch was incorrectly told it had already landed. Fixed: condition
is now crlfCount >= bareLfCount; the test fixture corrected to a
genuine 2:1 majority, with a new explicit tie-case test.

MAJOR — phase.cts's cmdPhaseInsert built an EOL-aware bulletEntry via
detectEol(rawContent), justified by a comment claiming a hardcoded
'\n' corrupts a CRLF ROADMAP.md. False: this write goes through
platformWriteSync, whose normalizeContent/_normalizeMd unconditionally
converts CRLF->LF for any .md target — the templating was inert dead
code, erased before the file is ever written. Reverted to hardcoded
'\n', comment corrected to state the true reasoning. The separate
[^\n]* -> [^\r\n]* widening one function up (a real splice-position
fix, independent of final EOL) was kept.

MAJOR — roadmap-upgrade.cts's stated rationale for switching onto
splitLines/joinLines was wrong (both functions always agreed on line
representation, before and after — the claimed equality-check risk
never existed), and the change it justified introduced a real
regression: forcing every line onto one dominant terminator silently
rewrites untouched lines' EOL on a mixed-CRLF/LF ROADMAP.md. This
write path uses raw fs.writeFileSync, not platformWriteSync, so unlike
the phase.cts case above the regression is genuinely live.

Fixing this took two attempts. The first attempt (revert to
split('\n')/join('\n') plus a suppression comment) was correctly
blocked by an agent that discovered local/no-crlf-fragile-split is a
PROTECTED_RULES entry in tests/portability-rule-disable-ban.test.cjs —
a hard, out-of-band, ADR-1703-governed guardrail banning any
eslint-disable of this rule anywhere in src/**/*.cts. That agent also
detected and correctly disregarded an injected instruction that
appeared in tool output during a git operation, per this session's
untrusted-content policy. The actual fix: computeMigrationPlan
reverted to roadmapContent.split('\n') (confirmed lint-clean — the
rule's data-flow tracking only follows a variable's initializer, and
this one is declared empty then reassigned in a try block).
applyMigration's write-back now splices edits against the ORIGINAL
content string via indexOf('\n', pos) boundary-walking instead of a
full split/rejoin, so every untouched character — including every
line's own terminator — is copied byte-for-byte. A capture-group split
(/(\r\n|\n)/, preserving terminators inline) was tried first and
empirically confirmed to still trip the rule before this approach was
chosen instead.

MINOR (security) — roadmap.cts's cmdRoadmapAnnotateDependencies used
the STRING form of String#replace, so $&, $`, $', $1-$9 inside
must_haves.truths content (author-controlled) were interpreted as
replacement directives, splicing unrelated ROADMAP.md text into the
result. Fixed with the function-replacement form, which is never
pattern-interpreted. Verified before/after with the reviewer's exact
repro.

Also disclosed rather than silently left: test matrix row 31 (four
planned CRLF-materialized regression tests) was never implemented as
separate files — corrected to record the actual verification (a
manual --check run plus incidental existing coverage via each script's
normalizeLineEndings: normalizeEol alias). parseMustHavesBlock's LF
behavior was claimed byte-for-byte unchanged but the old
yaml.indexOf(blockMatch[0]) substring search could match an unrelated
earlier occurrence of the header text (e.g. inside a quoted value) —
the split-then-scan fix incidentally also closes this, a strict
improvement now recorded in the design doc rather than left implicit.

* fix(#3413): checkpoint 2 red — missing eslint ignore entry, RuleTester config error

Checkpoint 2 came back red with 5 failures on the reviewed sha, both
gaps genuinely undetectable by any local gate.

eslint.config.mjs was missing the 'gsd-core/bin/lib/text-lines.cjs'
ignores-list entry (ADR-457: generated .cjs artifacts are excluded from
direct type-aware linting). Phase 1's sibling entry (pattern.cjs) sits
two lines above it and was the exact precedent read while researching
the six-gate ripple for this module -- missed anyway. Caught by
tests/repo-invariants.test.cjs's bin/lib coverage-tracking test, which
only runs on the remote suite.

tests/no-crlf-fragile-split.rule.test.cjs's row-32 case specified both
`messageId` and `message` on the same RuleTester error assertion --
ESLint's RuleTester rejects that combination outright. This existed
since the test was first authored and was never caught locally: `npx
eslint` only lints the file's syntax, it does not execute RuleTester,
and local `node --test` is hard-blocked in this repo -- the assertion
had never actually RUN before this checkpoint. It was even present in
checkpoint 1's failure list, listed there as one of the "expected RED"
tests; I matched it against my expected-failures list by test NAME
only and never inspected the actual failure detail closely enough to
notice it was failing for the wrong reason (a RuleTester config error,
not the intended message-text mismatch). Fixed by keeping `message`
(the exact-text assertion the test exists to make) and dropping
`messageId`. Verified the crlfFragileSplit message string in
eslint-rules/no-crlf-fragile-split.cjs matches this assertion
character-for-character, and swept every other invalid case in the
file for the same double-specification bug (none found -- all
pre-existing cases use messageId alone).

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

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

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

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

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

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

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

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

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

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

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

Three findings from the orthogonal review pass, all fixed.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

42729b21fa fix: scan bin/lib subdirectories in the inventory-manifest generator
gen-inventory-manifest.cjs's cli_modules family did a flat readdirSync
of gsd-core/bin/lib/, invisible to anything shipped in a subdirectory.
Found while registering this phase's 8 health-diagnostic-rules/*.cjs
files in docs/INVENTORY.md (Standards-axis review) — the automated
manifest cross-check couldn't see them even though the manual
INVENTORY.md rows were correct.

Adds collectOneLevelSubdirs (mirrors the existing collectNested's
defensive statOrNull style) and merges flat + one-level-subdirectory
results into cli_modules's single sorted array, using the same
<subdir>/<file>.cjs key format INVENTORY.md's rows already use.

Regenerating the manifest surfaced that three OTHER existing
subdirectories (installer-migrations/, host-integration-adapters/,
observability/ — pre-existing, unrelated to this phase) were equally
invisible and had zero docs/INVENTORY.md rows at all. Added all 15
missing rows rather than leave a gap the fix itself just exposed.

Also fixes 3 pre-existing lint-legacy-dir-name violations in the
installer-migrations rows (legitimate references to the historical
get-shit-done -> gsd-core rename these migrations clean up — marked
with the guard's own gsd-allow-legacy-name exemption) and a stale
health-diagnostic.cjs row that still said "RULES ships empty."

e0021a2fed refactor(#3309): extract health-diagnostic-types leaf module, wire RULES
Wiring all 8 rule-group files into health-diagnostic.cts's RULES array
created a genuine CJS circular dependency: each group file required
health-diagnostic.cjs back for the shared enums, and health-diagnostic.cjs
now required the group files forward, so the enums were undefined
mid-load (destructuring health-diagnostic.cjs's still-unassigned
exports).

Fixes it by splitting the enums/types (SEVERITY, REMEDY_ACTION,
REMEDY_RISK, Remedy, Diagnostic, Rule) into a dependency-free leaf
module, health-diagnostic-types.cts, that both sides import instead of
each other. health-diagnostic.cts re-exports the enums for existing
consumers. RULES is now the real concatenation of all 8 groups (31
codes — E001 intentionally stays a pre-check outside the table).

consolidated §7 owners (getMilestoneInfo, listMilestonePhaseDirs,
isPhaseComplete, scanPhasePlans, stateFieldValue, planningPaths) plus
the frozen SCOPE enum. No new semantic derivation is introduced beyond
worstScope, a pure combinator folding several independently-scoped
owner answers into one composite signal.

Adds STATE_UNREADABLE to src/unusable-input.cts's UNUSABLE_REASON
(seventh #1879 site) for STATE.md exists-but-unreadable, distinct
from absent.

Adds scripts/lint-planning-snapshot-bypass-drift.cjs, a ratcheted
drift guard (ADR-3180 Decision 4(e)) scoped to DIAGNOSTIC_RULE_FUNCTIONS
(currently cmdValidateHealth in src/verify.cts only) preventing new
raw .planning/ reads from bypassing the snapshot, while acknowledging
cmdValidateHealth's existing 15 raw-read sites as debt owned by
Phase 11 (#3309).

Six-gate .cts ripple: .gitignore, eslint.config.mjs,
docs/INVENTORY.md + manifest regen, CONTEXT.md glossary entry.

Breaking changes: none. This phase adds the subject only; Phase 11
migrates cmdValidateHealth onto it.

2076d450d7 fix(#2652): gate quick/diagnose dispatch on dispatch.isolation, not the runtime name (#2728)
* fix(#2652): gate quick/diagnose dispatch on dispatch.isolation, not runtime name

quick.md and diagnose-issues.md kept the pre-#2584 `RUNTIME != "claude"`
worktree gate, so every non-Claude runtime failed closed regardless of the
capability it negotiated — including Codex, which declares
orchestrator-worktree. Route both through the negotiated dispatch.isolation
seam via a new shared reference, and migrate the two execute-phase reference
fragments that carried the same runtime-name gate.

- new gsd-core/references/dispatch-isolation-gate.md: canonical ISOLATION
  resolution, harness-flag resolution, single-agent degrade rule
- quick.md / diagnose-issues.md read the gate; dispatch uses the {harnessFlag}
  placeholder rather than a hardcoded isolation="worktree"
- execute-phase-wave-guard.md / execute-phase-between-wave-reset.md: migrate
  [ "$RUNTIME" = "claude" ] -> [ "$ISOLATION" = "harness-worktree" ]
- every degrade site now clears BOTH USE_WORKTREES and ISOLATION; clearing one
  dispatched an isolated agent with no base guard and no manifest
- parity guard in host-integration.test.cjs scans workflows AND references and
  matches six reintroduction shapes
- migrate four tests that pinned the pre-#2584 runtime-name contract

path.relative() returns backslash-separated paths on Windows, so the
#2652 dispatch-site parity test compared "gsd-core\workflows\quick.md"
against the hardcoded forward-slash literal "gsd-core/workflows/quick.md"
and failed on every windows-latest CI lane. Normalize with
.replace(/\\/g, '/'), matching the existing convention used elsewhere in
this suite (e.g. tests/branch-no-track-guard.test.cjs:37).

* test(#2652): restore the size-growth acknowledgment

The rebase dropped tests/emitted-drift-ack.json. #2757/#2758 fixed the
ATTRIBUTION axis, but the SIZE-GROWTH axis is independent: diagnose-issues.md
(+2086) and quick.md (+230) still need an ack naming them and saying why.

* fix(#2652): convert execute-plan.md Pattern A onto the dispatch-isolation gate

Pattern A hardcoded `isolation="worktree"` — Claude Code's own literal —
gated only on `workflow.use_worktrees`, with no capability negotiation at
all. It is the same defect #2652 fixes at the other four sites, just a
different shape: the file contains no RUNTIME variable, so the new detector
correctly does not flag it.

Concrete break: a Codex user who follows this PR's own newly-documented
pattern and sets `workflow.use_worktrees: true` to get isolated dispatch via
/gsd:quick then runs a plan through /gsd-execute-plan Pattern A, and hits an
unconverted path — either an Agent() call erroring on an unrecognized
parameter or silent unisolated execution, depending on host tolerance.

Pattern A is a single-agent dispatch site through the host's own subagent
tool, so it takes the same treatment as quick.md and diagnose-issues.md:
resolve ISOLATION/HARNESS_FLAG through the canonical reference, degrade to
sequential on orchestrator-worktree hosts, and substitute the host's declared
{harnessFlag} instead of Claude Code's literal.

while the area was open.

* docs(#2652): add the INVENTORY row for dispatch-isolation-gate.md, refresh CONTEXT

Two bookkeeping gaps flagged in review:

INVENTORY.md had no row for the new gsd-core/references/dispatch-isolation-gate.md.
INVENTORY-MANIFEST.json was regenerated correctly and its --check only diffs a
live directory scan against the committed manifest, so CI passed regardless —
but gen-inventory-manifest.cjs's own stderr guidance says to add the matching
INVENTORY.md row. This is the repo's named "Inventory Drift" pattern. Placed
with the dispatch/isolation cluster (worktree-branch-check, runtime-aware-dispatch)
rather than alphabetically, matching how that table is grouped.

CONTEXT.md's Host-Integration Interface entry still described dispatch.isolation
as "declared and negotiated but not yet consumed by any scheduler — Phase 1 of
#2584". That was already stale before this PR (execute-phase graduated in Phase 3)
and more so now with three single-agent dispatch sites consuming it.

* test(#2652): detect reversed-operand runtime gates; add a permutation property

All five reintroduction regexes assumed $RUNTIME on the LEFT of the
comparison, so `[ "claude" != "$RUNTIME" ]` — the same gate written
backwards — evaded every one of them. Verified against the old patterns
before fixing: all four reversed shapes (single bracket, double bracket,
test builtin, JS template) scored EVADED.

Each comparison shape is now generated in both operand orders from a single
template, so a shape cannot be added in one order and forgotten in the other.
The mutation table gains the four reversed cases.

Also adds the fast-check property review suggested in place of the hand-rolled
cases: it generates the cross product of the axes an author actually varies —
bracket form, operator, operand order, quoting, spacing, runtime id — so a
permutation the hand-written patterns miss surfaces here rather than in
production. The 11 explicit cases stay as named regression anchors.

execute-plan.md joins the scan's required-identities list now that it is a
converted dispatch site.

* test(#2652): repin the execute-plan.md PROSE_ALLOWLIST line after the rebase

The #2751 command-position gate pins its prose exemptions by line number.
This branch inserts the dispatch-isolation resolution above the
`validated downstream by gsd-tools uat classify-coverage` sentence, moving
it from execute-plan.md:387 to :397 — which fired the gate twice for one
displacement (an un-allowlisted mention at 397, a stale entry at 387).
The prose itself is unchanged from next; only the pin moves.

Fixes #2652

* fix(#2652): gate the #2649 base-check on ISOLATION in diagnose-issues.md

The rebase onto next merged #2649's pre-dispatch base-check textually, but
its degrade flipped USE_WORKTREES after ISOLATION was already resolved, so
the degrade never reached the dispatch decision. Gate the block on
ISOLATION = "harness-worktree" and degrade ISOLATION itself, the same
pairing quick.md already uses.

* fix(#2652): key quick.md post-dispatch bookkeeping on ISOLATION, not the Claude literal

Review Blocker: the manifest append (l.822), worktree merge-back (l.825), and
its skip clause (l.839) all conditioned on the literal isolation="worktree" —
Claude Code's own rendering of {harnessFlag}. Cursor renders --worktree, so a
newly-unblocked isolated Cursor run created a worktree whose committed work
was never merged back and never cleaned up, silently. All three now key on
ISOLATION = "harness-worktree" at dispatch.

The existing parity detector cannot catch this class (its ISOLATION_TOKEN
treats the literal as a legitimate marker), so this adds a dedicated
literal-condition detector with a discrimination proof against both pre-fix
sentences, a benign-mention control, and a positive pin on all three
re-keyed conditions. Verified fail-first against the pre-fix quick.md.

* fix(#2652): scope the use_worktrees=false install stamp to isolation=none runtimes

`_stampNonClaudeRuntimeDefaults` rewrote every non-Claude runtime's
`workflow.use_worktrees` read to `--default false`. That default resolved
before `gsd_run query dispatch-isolation` was ever consulted, so the five
runtimes that declare worktree support — cursor (harness-worktree) and
codex/opencode/kimi/kimi-code (orchestrator-worktree) — got ISOLATION=none
regardless of what they negotiated. The gate this PR migrates dispatch onto
was therefore still deciding isolation by runtime name, one layer down.

The stamp's #1521 premise was that worktree isolation *was* Claude Code's
isolation="worktree" spawn parameter, which no other host honored. #2584
replaced that premise with the negotiated capability. The stamp is now scoped
to runtimes whose negotiated isolation really is `none`, where the default it
writes is the outcome the resolver reaches anyway.

`_negotiatedDispatchIsolation` mirrors routeDispatchIsolation's resolution
against the same registry — closed vocabulary, a harness-worktree host must
declare its flag, an orchestrator-worktree host must carry a descriptor that
resolves — and fails closed to `none` on anything else, so an undeclared or
unknown runtime keeps today's behavior.

Two #1515 tests pinned the superseded premise for codex and are re-pointed at
the new contract rather than deleted: the safety property they protect is now
held by the isolation gate's fail-closed resolution, not by a name-scoped
install-time default. Verified fail-first — all five assertions red against
the pre-fix source, green after.

* test(#2652): acknowledge the emitted ripple and re-point the end-to-end stamp proof

Scoping the use_worktrees stamp changes emitted output, and two gates caught it.

`gsd-core/workflows/execute-phase.md` now differs at emit time for the five
hosts that declare worktree support (cursor harness-worktree; codex, opencode,
kimi, kimi-code orchestrator-worktree) — the source file is byte-identical, only
the stamp is gone. Acknowledged in this PR's fragment.

`tests/install.test.cjs`'s real-install assertion pinned the superseded premise
end-to-end, asserting codex receives `--default false`. Re-pointed rather than
deleted, matching the two unit tests: it now proves codex keeps the unstamped
`true` read. A second arm installs windsurf — which declares isolation `none` —
and asserts the false stamp is still applied there, so the change cannot
silently degrade into "never stamp" without a test noticing.

The ack entry collides with `2658-trae-instruction-file-path.json`, which is
fully spent (merged via #2925, so all 25 of its entries are present at base and
gate nothing) and is pruned for the same reason and by the same rule as the
spent `2649-*` fragment this PR already removed. #2566 prunes the same file for
the same collision on `new-project.md`; a delete/delete merges cleanly either
way, and the base-side cleanup would make both unnecessary.

* fix(#2652): re-record the sentinel when a dispatch site degrades isolation

Review Blocker B1/B2/B3. Every isolation degrade in a dispatch site is decided
in shell, where routeDispatchIsolation cannot see it. That resolver persists
whatever it resolved to the run-scoped sentinel as an unconditional side effect
(#3045), so a degrade that only reassigns $ISOLATION leaves the sentinel
asserting harness-worktree while the dispatch correctly omits the harness flag.
The shipped PreToolUse guard reads the sentinel at the instant of the Agent()
call and denies that mismatch with exit 2 — the work does not run unisolated,
it does not run at all. Latent on this branch and lands on rebase, since
8f75e275 (#3045) is not yet in the merge-base.

Four sites now push the final shell-computed value through the same single
write path with --force-isolation, matching the idiom #3045 established in
executor-isolation-dispatch.md:

  - quick.md, after the #1941 base-check degrade
  - diagnose-issues.md, after the config-gate degrades and after #2649's
  - execute-plan.md Pattern A, before spawning
  - references/dispatch-isolation-gate.md, both degrade paths, plus a new
    "Re-record after every degrade" section — the canonical file taught the
    defect, so fixing only the call sites would leave the source of truth wrong

Tests assert the RECORDED value, not $ISOLATION. Asserting the local variable
is what let this class through: $ISOLATION was already `none` at every site and
the defect was entirely in what reached the sentinel. Each workflow's own
degrade block is executed under a gsd_run stub that captures the write, with a
fail-first proof that the pre-fix shape records nothing (while $ISOLATION reads
`none` in both), plus a coverage guard so a new degrade site cannot skip it.

Also corrects the drift-ack rationale (review Minor 5): @-references are
eagerly inlined, so extracting the gate does not reduce loaded context. The
reason to extract is single-sourcing across five dispatch sites.

* fix(#2652): restore next's 2658 ack fragment, minus the one colliding key

trek-e (PR #2728, 2026-08-07): the branch deleted
tests/emitted-drift-acks/2658-trae-instruction-file-path.json wholesale
while next had modified it. That was correct against the 08-03 base, where
the fragment was fully spent; it is wrong against next @ 1d208e5a, which
still carries 23 live entries.

next's copy is restored byte-identical except for the single key that
genuinely collides with this PR's own fragment,
gsd-core/workflows/execute-phase.md. Both acks name that path for
different deltas -- 2658's is the trae CLAUDE.md replacement-target
rewrite, ours is the emit-time _stampNonClaudeRuntimeDefaults ripple from
review round 3. Per the ack-lifecycle law (#2789), an entry already at the
base is spent and inert, so this PR's entry is the live one and 2658's is
dropped.

This follows the guidance given on #2566 in the 08-06 round: "Regenerate
rather than delete -- the collision is one entry."

Verified: lint-emitted-drift-ack ok (0 problems, 357 keys, no cross-source
duplicates); emitted-attribution 170/170 with GSD_EMITTED_BASE=upstream/next;
host-integration 222/222; runtime-converters 130/130.

* fix(#2652): bound the degrade-harness spawn and close the round-6 majors

B1 (CI red, ours): tests/host-integration.test.cjs spawned bash with no
timeout, violating local/no-unbounded-spawn. `next` deleted the allowlist
outright (#3148), so the merge-commit run flags it even though this branch
still carries the file's grandfathered entry. Bounded at 15s, with a named
failure on timeout/signal rather than an opaque `exited null`.

M1: add a parity test between `_negotiatedDispatchIsolation` (install time)
and `routeDispatchIsolation` (dispatch time). Both read the same capability
registry and the same `resolveOrchestratorExec`, but duplicate the DECISION
on top of them across two surfaces with no call edge between them, so neither
symbol appears in the other's impact graph and nothing static can catch them
drifting apart. The resolver leg drives the real gsd-tools CLI per registered
runtime, both ways it is really called: with `--cwd-target` (the executor
spawn, which resolves the orchestrator descriptor — the same question install
time asks) and without it (the `Resolve ISOLATION` call every dispatch site
makes first, which does not). The second leg is what catches an orchestrator
host whose descriptor stops resolving: the install would stamp
`use_worktrees=false` while the workflow gate still reported
`orchestrator-worktree`.

M2: add install-level Cursor coverage. A real `--cursor` install, then the
gate blocks that install emitted, run against the gsd-tools that install
emitted, with the runtime declared through `.planning/config.json` — the tier
`resolveRuntime` actually reads — and any ambient GSD_RUNTIME blanked, so the
install has to reach the right resolver on its own. It then performs the
documented `{harnessFlag}` substitution against the `Agent()` call that
install emitted and asserts on the rendered dispatch: exactly one emitted
Agent() call carries the slot, it is the gsd-executor / gsd-debugger dispatch
rather than some other call in the same file, and rendering it yields
`--worktree` with no residual placeholder and no `isolation="worktree"`.
This is artifact-level — it proves the emitted wiring, not a live Cursor
host invocation. Asserting the shell variable alone would have stayed green
if the placeholder were deleted from the emitted dispatch, or drifted onto
the reviewer call beside it.

M3: diagnose-issues.md inlined a reordered copy of the reference this PR
introduces as the single source of truth. It now reads the reference the
same way quick.md and execute-plan.md do; the drift-ack entry is corrected
to describe what the file actually contains, and to name the four files that
reference the gate rather than claiming five.

M4: CONTEXT.md still called `resolveOrchestratorExec` UNCONSUMED in the same
paragraph this PR edits. It has been consumed since #2584 Phase 3 — routed
through `query dispatch-isolation --json` and process-spawned by
executor-isolation-dispatch.md — and #2652 adds a second consumer.

Every new assertion verified fail-first against a real mutation: cursor's
negotiated isolation (breaks the target-bound parity leg), the no-target
orchestrator branch in routeDispatchIsolation (breaks the gate parity leg),
cursor's harnessIsolationFlag (breaks the resolved value), deleting
`{harnessFlag}` from quick.md's emitted Agent() call (breaks the slot), and
moving it onto the code-reviewer dispatch (breaks the wrong-call guard).

Refs #2652

* fix(#2652): serialize unisolated diagnosis, scope the execute-plan gate to dispatching patterns

Round-7 review findings (independent cross-AI pass over the whole PR against
the current base).

BLOCKER — diagnose-issues.md announced sequential mode and then fanned out.
The `orchestrator-worktree` degrade sets ISOLATION=none and prints "debug
agents run sequentially on the main working tree", but the spawn step still
said "All agents spawn in single message (parallel execution)". On Codex,
OpenCode and Kimi that dispatched N unisolated debuggers concurrently against
the primary checkout — the exact outcome the degrade exists to prevent, and
reachable only because this PR removed the FATAL that used to stop those
hosts earlier. Fan-out is now keyed on ISOLATION: parallel only when each
agent has its own worktree, one at a time otherwise.

BLOCKER — execute-plan.md Pattern B could not dispatch at all on Claude or
Cursor. The gate recorded `harness-worktree` to the #3045 sentinel, but only
Pattern A carries `{harnessFlag}`; Pattern B's segment executors carry none,
and `hooks/gsd-agent-isolation-guard.js` blocks precisely that mismatch with
exit 2. Segments are unisolated BY DESIGN — each continues on the working
tree the previous one left behind, so per-agent worktrees would break the
sequence — so Pattern B now records `none` before its first dispatch and
dispatches without the flag.

MAJOR — the same gate ran before routing was chosen, so an isolation-`none`
host with `use_worktrees=true` hit the fail-closed FATAL even when routing
would have selected Pattern C, which is fully inline and dispatches nothing.
Resolution now happens after the pattern is known, and Pattern C skips it.

MAJOR — tests/host-integration.test.cjs fed `fs.readFileSync` output straight
to bash. The `\r?\n` fence regex guards only the delimiter, leaving embedded
CR on every line of the captured body — DEFECT.WINDOWS-CRLF-TEST-PORTABILITY,
which helpers.cjs documents by name. Now reads through `readFileNormalized`.

MAJOR — the "every dispatch-site degrade block re-records" test hand-listed
three files, so its name was a claim its scan could not support. The scan is
now derived from the workflow/reference tree (SCAN_ROOTS/collectMarkdown
hoisted to module scope so there is one definition, not two). Verified
fail-first against execute-plan.md — a file the previous scan never opened.
The two wave fragments are exempt because they delegate the re-record to
per-plan-worktree-gate.md via USE_WORKTREES_FOR_PLAN; that delegation is now
ASSERTED, so deleting the delegate fails this test instead of widening a hole
silently.

MINOR — the changeset claimed the FATAL was gone for "non-Claude runtimes"
full stop. Narrowed: isolation-`none` hosts still fail closed when worktrees
are explicitly enabled, which is the contract rather than the defect.

Two further findings were investigated and rejected, with evidence:
- Raw `spawnSync` vs `tests/helpers/process-seam.cjs`: the seam exposes
  runNode/runGit/runHook and cannot express the `bash -c` harness these tests
  need; `installAndRead` in this same file is byte-identical to the base and
  still uses raw spawnSync with an explicit timeout, which is the form the
  lint sanctions. Migrating only the new call sites would split the file's
  convention for no safety gain.
- `pending-migration-to-typed-ir` on the runtime-converters parity test: the
  annotation and the rendered-text loop both exist at the merge-base under
  #3090. This PR extends an already-tracked test rather than adding a new one
  under a category CONTRIBUTING closes to new tests.

Refs #2652

* test(#2652): re-point the execute-plan prose allowlist at its shifted line

`PROSE_ALLOWLIST` in tests/no-bare-gsd-tools-command-position.test.cjs keys
entries by LINE NUMBER. The previous commit added the post-routing isolation
block to execute-plan.md, which pushed the `validated downstream by
gsd-tools uat classify-coverage` prose mention from line 397 to 414. That
broke the guard in both directions at once: the entry at 397 went stale, and
the real mention at 414 became an unallowlisted offender.

Caught by CI (7 red jobs, all shard 3/3 plus ubuntu-22) rather than locally,
because I verified only the suites I believed the change touched. Any edit to
a workflow .md shifts line numbers, and this repo carries line-keyed
allowlists — so a workflow edit needs the full suite, not a subset.

Refs #2652

* test(#2652): route the new subprocesses through the process seam

Retracting a rejection I made on the record. In the round-6 response I
argued these call sites could keep a hand-rolled `spawnSync` because the
seam exposes only runNode/runGit/runHook and cannot express `bash -c`, and
because `installAndRead` in the same file uses that shape. The first half
was true and irrelevant, the second half is not a licence: CONTRIBUTING is
unambiguous — "Anything that shells out goes through
tests/helpers/process-seam.cjs — never a hand-rolled spawnSync/execFileSync
in your suite", and "Never use try/finally inside test bodies."

`runHook` already documents `interpreter: 'bash'` for running a shell
script, so writing the harness to a file complies without extending the
seam. I had the rule and the seam's own documentation in front of me and
reasoned around both.

Converted:
- host-integration.test.cjs degrade harness: spawnSync('bash', ['-c', …])
  → runHook(scriptFile, [], { interpreter: 'bash' }).
- install.test.cjs cursor gate: `which bash` probe → process.platform;
  the installer spawn → runNode(…, { env: installSpawnEnv({HOME,
  USERPROFILE}) }), which also blanks ambient GSD_HOME/runtime-location
  vars that could otherwise make capability discovery host-dependent;
  the emitted-gate spawn → runHook(gateScript, [], { interpreter: 'bash' }).
- Three try/finally test bodies → t.after().

Class-norm timeouts: tests/helpers/timeouts.cjs arrived with this branch's
latest base merge, so the literals written earlier (15000/120000/60000) now
duplicate PROBE_TIMEOUT_MS and INSTALL_TIMEOUT_MS. Imported instead — that
module exists because INSTALL_TIMEOUT_MS had already drifted 60s→120s once
after a real bench ETIMEDOUT.

Deliberately NOT converted: `installAndRead`'s spawnSync, which is
byte-identical to the merge-base and predates this PR — converting shared
scaffolding is an unrelated change.

Verified equivalent, not assumed: argv/cwd/env/encoding/timeout and every
assertion are preserved; t.after() still cleans up on the assertion-failure
path the try/finally covered; and the cursor test still resolves Cursor
under a hostile ambient GSD_RUNTIME=claude.

Refs #2652

* fix(#2652): replace the falsified use_worktrees doc row; distinguish an unresolvable gate from a declared none

Round-8 review findings.

BLOCKER — docs/CONFIGURATION.md's `Non-Claude note` asserted three things
this PR overturns: that worktree isolation "no other runtime honors"
(Cursor declares harness-worktree with `--worktree`, and this PR's own
install test asserts that flag reaching the emitted Agent() slot), that
non-Claude installs default the key to `false`, and that forcing `true`
always fails closed. Replaced with the capability-based description, and
the `#1515, #1521` citation dropped — those are the two issues whose
premise this PR removes.

The reviewer flagged that the fix is merge-order dependent, because #2531
rewrites the same row and its replacement text is written in anticipation
of this PR landing. Rather than pick an order, BOTH sides are now
order-independent: #2531's "Current default … until #2652" paragraph
becomes a plain troubleshooting note, and this row states the capability
rule without asserting a stamp state. Whichever merges first, the row is
correct; the second merge is a textual conflict at worst.

MINOR — the gate reported a capability verdict the tool never returned.
`ISOLATION=$(… || echo "none")` made a shim-resolution failure, a non-zero
exit and an empty stdout indistinguishable from a declared `none`, so a
transient query failure aborted /gsd:quick on Claude Code with "runtime
'claude' declares no executor-isolation primitive" — false. The gate now
tracks ISOLATION_RESOLVED separately: both paths still fail closed, but only
a real verdict claims the host declares nothing; the unresolved branch says
it could not resolve and points at the shim. Fixed in the canonical
reference so every dispatch site inherits it.

MINOR — quick.md:527 cited #2649 for its own degrade; that is #1941, and
#2649 is the diagnose-issues/execute-plan gate. Corrected, and the
distinction stated so the next reader does not chase it.

MINOR — quick.md:413 (manifest init) and :429 (worktree_branch_check embed)
still branched on USE_WORKTREES while dispatch, manifest-append, merge-back
and the skip clause had all moved to ISOLATION. Safe only by coincidence —
both now key on ISOLATION.

MINOR — the diff removes a second drift-ack entry (the execute-phase.md key
from 2658-trae-instruction-file-path.json), forced by the same duplicate-key
lint rule as the 2649 removal. Disclosed in the PR comment; the earlier
disclosure covered only one of the two.

Verified: lint:ci green; 300/300 across host-integration,
fix-1941-quick-worktree-stale-base, execute-phase-wave and workflow-guard.

Refs #2652

* test(#2652): anchor the emitted-gate finder on the heading, not the assignment

`b89c3fbf` added a finder that located the gate's `Resolve ISOLATION` block by
the literal `ISOLATION=$(gsd_run query dispatch-isolation --raw`. `f3bccf21`
then split that assignment into `_ISOLATION_RAW`/`ISOLATION_RESOLVED` so a shim
failure stops masquerading as a declared `none` — and the finder stopped
matching. The test did not report the drift it exists to catch; it reported
"emitted dispatch-isolation-gate.md has no Resolve ISOLATION bash block" and
went red, and stayed red because the earlier full-suite run was read from a
truncated log.

Anchored on the heading instead. The workflows tell a dispatch site to run the
`Resolve ISOLATION` and `Resolve the harness flag` blocks BY NAME, so the
heading is the contract and the body is free to change under it.

Verified: 413/413 in tests/install.test.cjs. The test still bites — mutating the
gate's `ISOLATION="$_ISOLATION_RAW"` to `ISOLATION=none` turns it red (the
emitted gate then resolves cursor to none and exits 1 instead of printing
harness-worktree), and reverting restores green.

* fix(#2652): wire the canonical resolver at the one dispatch site that still inlined the old shape

Codex review of the whole PR on the new base found one Major, and it was real.

executor-isolation-dispatch.md declares references/dispatch-isolation-gate.md
canonical at line 10, then kept the OLDER resolver inline: `|| echo "none"`, no
ISOLATION_RESOLVED. So the one site that resolves isolation for the wave path
collapsed a shim failure into a declared `none` and aborted with "runtime
'$RUNTIME' declares no executor-isolation primitive" — false for a Claude or
Cursor user whose resolver merely failed to answer. Still fail-closed, so not an
unsafe-dispatch hole, but the correction this PR is about was unwired at the
site that matters most.

Replaced with the gate's exact shape: capture the raw value, track
ISOLATION_RESOLVED, and emit the "could not resolve" FATAL when no verdict was
learned.

Added a regression test in the #2652 dispatch-site parity suite: every file that
ASSIGNS from `gsd_run query dispatch-isolation --raw` must carry
ISOLATION_RESOLVED, must not use the collapsing form, and must have a distinct
unresolved message. Nothing covered this before — install.test.cjs checks the
emitted REFERENCE, not each site's own inline copy, which is exactly how the two
drifted apart.

The test's first draft also flagged quick.md, diagnose-issues.md and
execute-plan.md. That was a false positive worth recording: those three
@-reference the gate and only make `--force-isolation` re-record calls, which
carry no verdict. The predicate now matches an assignment from the resolver, not
any mention of it, so it flags sites that can actually be wrong.

Verified by mutation: restoring the collapsing line reds the new test.

Validated: lint:ci clean; full suite shows the same 7 known failures as the
pre-change baseline — #1160 _resolveManifest and the #3053 quick_id
host-timezone tests (both reproduce on pristine next @ 33fca50d), plus
helpers-cleanup "outside os.tmpdir()", which fails only in a worktree.

* test(#2652): close two vacuous-pass holes in the new inline-resolver guard

Codex cleared the push and flagged the guard test itself. Both holes were real.

SCAN_ROOTS already yields references/dispatch-isolation-gate.md, and the test
appended it a second time, so the candidate list was [executor, gate, gate] and
`length >= 2` was satisfiable by the gate alone. If the executor site had
dropped out of the predicate — the exact regression the test exists to catch —
it would still have passed. Paths are deduped and the assertion now pins the two
expected inliner identities instead of a count.

The collapse detector keyed on `ISOLATION=$(…)`, so `_ISOLATION_RAW=$(… || echo
"none")` restored the identical defect while satisfying every other assertion
(ISOLATION_RESOLVED still appears in the file). Codex mutation-probed exactly
that and it passed. The pattern now matches any assignment target and any
`|| … echo` tail. Verified: that mutation now reds the test.

Test-only change; the workflow bash is byte-identical to the commit the full
suite ran green against. lint:ci clean, host-integration 223/223.

7a7bf19fc1 enhance(#2872): record scope and runtime in the install manifest (#3323)
* enhance(#2872): record scope and runtime in the install manifest

gsd-file-manifest.json gains manifestVersion, runtime and scope, and a new
read-only Installed Surface Resolver Module reads both install scopes for a
runtime in one call -- the first code path in the repo that does.

Phase 3 of epic #2866 (ADR-2866). Blocks Phase 4 (#2873), which resolves
#2218: the resolver's shadowedBy field is that defect expressed as a value
for the first time. It ships computed-and-unread here.

Installed-ness is decided by manifest PRESENCE, never by the new fields, so
a manifest written by an older GSD stays fully functional and no user needs
to reinstall. Recorded runtime/scope are corroboration: a disagreement with
the probed config dir is reported as declaredScopeMatchesProbe: false, never
silently corrected.

readInstallManifest is widened additively -- version/timestamp/mode/files
keep their exact names, types and meanings for all four existing callers.
manifestVersion is a new field rather than a reinterpretation of version,
which holds the package version and is read by the golden-parity fixtures.

Stems are derived from the installed manifest's own file keys, the inverse
of Phase 2's filename composition, guarded by a fast-check round-trip
property plus a kebab-case charset check so a crafted manifest key cannot
put a traversal segment, control character or ANSI escape into a trigger
that Phase 4 renders back to the user.

Also fixes two defects found while working:
- bin/install.js hardcoded manifestVersion: 2 while the reader owned
  MANIFEST_SCHEMA_VERSION = 2. Now single-sourced, with a parity test.
- docs/installer-migrations.md documented an install-state schema of five
  snake_case fields that have never been written; InstallState has only ever
  been { schemaVersion, appliedMigrations }. Corrected with a dated note.

Verification runs on the remote runner.

* fix(#2872): fold review findings from three independent engines

Standards axis:
- convert the manifest-schema suite from a hybrid setup(t) closure to
  beforeEach/afterEach (CONTRIBUTING.md:319-354 Pattern 1). The hybrid was
  neither approved pattern and a new test forgetting the call got no warning.
- SCOPE_ORDER was declared twice with no parity test -- this repo's recorded
  generative-fix-divergence class. Give the ordering one owner: install-scope
  exports it frozen, the layout module and the resolver both import it, and a
  test locks it against scopeRank so the constant and the ranks cannot drift.
- drop the defaultReadManifest passthrough (Middle Man).

Spec axis:
- add the VOLATILE_FILES exclusion test and source comment the acceptance
  table promised and did not deliver. gsd-file-manifest.json stays excluded:
  the new fields are deterministic, but timestamp -- the original reason --
  is unchanged.

Security axis:
- bound the reported manifest runtime at 64 chars, matching the
  truncatePostureValue convention already used in this subsystem. It reached
  declaredRuntime unbounded while the adjacent stems were gated by SAFE_STEM;
  an inconsistent posture on the same attacker-influenceable document. The
  charset stays ungated on purpose -- declaredRuntimeMatchesProbe needs to see
  the real value -- so Phase 4 must sanitize before rendering, recorded in the
  design's Known limits.

Both new parity tests were verified to FAIL when the two sides are made to
disagree, then pass again on revert. Verification runs on the remote runner.

* chore(#2872): backfill changeset pr number to 3323

* fix(#2872): give git fixture construction its own timeout class

PR #3323's full test (windows-latest, 22, shard 2/3) failed with

  gitOrThrow: 'git init' failed -- outcome=timed_out exitCode=null
  gitOrThrow: 'git commit --allow-empty' failed -- outcome=timed_out

from drift-detection.test.cjs's beforeEach, a file this branch never touched.
Every other lane passed the same commit, including windows-latest node 24 on
all three shards, and next is green.

Root cause is a bound sized for the wrong class. DEFAULT_GIT_TIMEOUT_MS is
15000 and its own comment scopes it to plumbing READS -- rev-parse, branch,
log -- against an existing repo. createFixture uses it for six sequential
repo-CONSTRUCTION spawns: init, three config writes, add -A, commit. init and
commit each write dozens of files, and on Windows every spawn is
Defender-scanned. Sibling tests in the failing block took 15.6-22.0s against
a 15000ms bound.

This repo already diagnosed this exact shape once: timeouts.cjs's
HOOK_FANOUT_TIMEOUT_MS records PR #3285 failing in the SAME job with the SAME
outcome=timed_out exitCode=null signature at the SAME bound while every other
lane passed, and concludes 'a bound sized for the wrong class, not a slow
machine'. It was fixed by splitting out a heavier class-norm at 60000. Same
remedy here: GIT_FIXTURE_TIMEOUT_MS = 60000, 4x the bound that failed and half
INSTALL_TIMEOUT_MS.

DEFAULT_GIT_TIMEOUT_MS deliberately stays at 15000 -- a blanket raise would
stop a genuinely hung plumbing read from surfacing fast.

Verified the value reaches the spawn rather than being an ignored option:
spawnSync was monkeypatched before requiring the fixture module, and all six
git construction calls were captured carrying timeout: 60000.

This branch's two new test files shift shard composition, which is how a
pre-existing fragility landed in the heaviest shard on the slowest lane.
Fixed here rather than deferred, per the no-defer rule.

Verification runs on the remote runner.

* chore(#2896): convert CONTEXT.md prose defect registry into enforced gates

Squashes the prior 4-commit sequence and fixes defects found while
resuming this branch: 5 orphaned/corrupted DEFECT fragment lines left
by an earlier botched edit, 17 "Source of truth: Memtrace `find_symbol`"
placeholders that had destroyed real file-path citations, and 3
DEFECT.GENERATIVE-* entries merged into one RULESET.GENERATIVE-FIX
predicate (policy, not an unenforced defect) to satisfy the zero
DEFECT.<NAME>.<field>= acceptance criterion.

Six mechanizable defects get real gates: DEFECT.UNBOUNDED-SUBPROCESS

(scripts/lint-canary-version-leak.cjs + version-gate.yml),
DEFECT.CHANGESET-PR-FIELD-DRIFT (findPrFieldDrift in changeset/lint.cjs),
DEFECT.FRONTMATTER-SCALAR-BROAD-GREP, DEFECT.REMOVED-BUT-NEEDED, and
DEFECT.DEFAULT-FLIP-DOCUMENTATION (new lint scripts, wired into lint:ci).
Already-enforced and unenforceable prose entries are deleted; the gate

* chore(#2896): route the new lint tests' subprocess calls through the bounded process-seam helper

The 4 new test files for this PR's lint checks called cp.spawnSync/
execFileSync directly with no timeout, tripping this repo's own
existing local/no-unbounded-spawn ESLint rule. Route every one through
runNode/gitOrThrow (tests/helpers/process-seam.cjs,
tests/helpers/git-fixture.cjs) instead, matching the pattern already
used elsewhere in the suite (e.g. tests/changeset-lint.test.cjs).

* fix: register claude-orchestration.cjs and regenerate stale generated indexes

Pre-existing drift on next, unrelated to this PR's own change, surfaced
by running lint:ci as part of verifying #2896: two cli_modules
(claude-orchestration.cjs, write-set.cjs) landed without a manifest
regen, and CONTEXT.md's own edits in this PR staled its two generated
indexes. Adds the missing docs/INVENTORY.md row for
claude-orchestration.cjs (write-set.cjs already had one — only its
manifest entry was stale) and regenerates
docs/INVENTORY-MANIFEST.json, docs/CONTEXT-INDEX.json, and
examples/dynamic-context-management/CONTEXT-INDEX.json.

* fix(#2896): default-flip-documentation lint's local fallback base was main, not next

Found in review: every other base-ref fallback in this repo (see
scripts/changeset/lint.cjs's DEFAULT_BASE, #2988) defaults to `next`,
the integration branch every PR actually targets — `main` is the
release branch. This script's local fallback (used only when
GITHUB_BASE_REF is unset, i.e. never in CI, but potentially on a local
or direct invocation) diffed against the wrong ref. No test exercised
the unset-env-var path, so it shipped unnoticed; every e2e test sets
GITHUB_BASE_REF explicitly and is unaffected by this fix.

* fix(#2896): stale eslint comment, overclaiming CONTEXT.md wording, and an incompletely-regenerated manifest

Found by the isolated Standards code-review pass:
- eslint.config.mjs's require-subprocess-timeout comment said "'warn'
  for now... flip to 'error' once migrated" while the rule already
  shipped as 'error' with all 8 sites migrated in the same commit —
  described a state that never existed.
- The CONTEXT.md pointer block claimed the rule's bounded call sites
  "never throw", but roadmap-upgrade.cts's pre-mutation clean-tree
  check correctly still throws on failure (it gates a destructive
  real-run migration; degrading to "assume clean" would risk clobbering
  uncommitted work) — softened the claim to describe both shapes
  accurately instead of overclaiming one.
- docs/INVENTORY-MANIFEST.json's claude-orchestration.cjs/write-set.cjs
  entries from the prior "fix: register claude-orchestration.cjs..."
  commit didn't actually land — re-running the generator now includes
  them; lint:generated-sync is green.

* fix(#2896): normalize buildCorpus file paths to POSIX in lint-removed-but-needed

Windows CI caught it: path.relative(root, abs) returns backslash-
separated paths on Windows, but findSurvivingReferences's package-lock
special case does file.startsWith('.github/workflows') — a forward-
slash literal. On Windows the check silently never matched, so
tests/removed-but-needed-lint.test.cjs's real-defect-shape fixture got
exit 0 instead of the expected exit 1. Normalize at the production
source (RULESET.CONTENT-PATH-NORMALIZATION) rather than the test side.

96a82bbffb enhance(#3245): report the detected host runtime in init (#3307)
* test(#3245): failing-first coverage for host runtime detection in init

Locks the behavior epic #2313 Phase 5 must produce before any of it exists: init reports the detected host, explicit GSD_RUNTIME and config runtime still outrank detection, non-Codex sessions are untouched, and nothing is ever written to shared defaults (#2297).

* enhance(#3245): report the detected host runtime in init

init reported agent_runtime: claude inside a Codex session, and resolved agents_dir to the Claude agents root with agents_installed: true — a spuriously healthy triple. Runtime identity was only ever read from GSD_RUNTIME or an explicit runtime in .planning/config.json.

Adds a detection rung beneath both explicit sources, in a new pure module. Codex is identified from its own documented session environment (CODEX_SANDBOX / CODEX_SANDBOX_NETWORK_DISABLED), else an explicitly exported CODEX_HOME whose config.toml exists. The default ~/.codex is never probed: that file exists on every machine that has run Codex, so probing it would misreport other runtimes' sessions.

resolveRuntime keeps its exact contract and all 71 dependents, including formatGsdSlash command-style emission; only withProjectRoot consumes the new rung. Nothing is written on any path (#2297). Explicit config still wins (#2517).

* fix(#3245): make the parity guard real and single-source the marker

Four independent review passes found the generative-fix-divergence guard was vacuous: it asserted agreement at the one input where inferPreferredRuntime and detectHostRuntime do not differ, so it could not fail. It now pins the actual divergence point (CODEX_HOME set, config.toml absent) and records that the asymmetry is deliberate.

The config.toml marker is now single-sourced from update-context.cts and imported, rather than carried independently by two surfaces. tests/helpers.cjs now scrubs CODEX_SANDBOX and CODEX_SANDBOX_NETWORK_DISABLED: GSD reads them, so an ambient Codex session would otherwise make the non-codex control test fail non-deterministically.

Also: detection is throw-safe end to end rather than only around the fs probe; the Windows-join test is replaced with one that can actually fail (trailing-separator, catches hand-rolled concatenation); the #2297 no-write proof now wraps resolveReportedRuntime, the function that ships, across all three ladder outcomes.

d28ab7c8f7 enhance(#3243): sync installed codex .toml model/effort to the passive posture (#3296)
* feat(#3243): sync installed codex .toml model/effort to the passive posture

Implements ADR-2313 D7, and owns the Codex .toml typed IR that Phase 1's
review assigned to this phase.

The IR exists for a structural reason, not tidiness: this phase has to
PARSE these files, and a parser kept bug-compatible with a separate
renderer is the generative-fix-divergence shape this epic already dealt
with once for the model predicate. So Phase 2's parsing MOVES here
rather than being copied — agent-install-check now imports it, and its
test file passing unchanged is the proof the extraction altered nothing.

The load-bearing property is byte-identical round-trip: render(parse(x))
=== x. Without it a sync silently reformats a user's file — line
endings, key order, BOM, trailing newline — turning a two-line repair
into a whole-file diff in their dotfile repo. The IR keeps original
lines and removes targeted ones rather than reconstructing from parsed
fields, which is what makes that property hold.

It also reconciles a real contradiction between Phase 2 and ADR-2313. An
unterminated developer_instructions block: the reader excludes the rest
of the file, deliberately failing toward a false positive, because
misreading prose as a pin only wastes a user's time. The writer must
refuse, because proceeding on a malformed document rewrites it. A false
positive is the safe direction for a reader and the dangerous one for a
writer. So the parse reports the fact and the two consumers branch on
it — one parse, one truth, two policies, instead of two parsers that
agree today.

The sync leaves a legal real-Codex pin and its coupled effort untouched,
reported skipped rather than synced; strips a stale Anthropic or tier
model and an orphaned effort; keeps dry-run as the default; refuses any
file whose parse fails; and skips symlinks exactly as the Claude path
already did. The Claude path itself is byte-identical.

PARSE_REASON.NO_HEADER from the ADR's illustrative snippet is
deliberately not implemented — a missing header is legal, not an error,
so it would be a dead enum member that the enum-lock test then pins.

* fix(#3243): preserve per-line endings and make the codex write atomic

Two findings from an isolated review, both in the write path.

BLOCKER: mixed line endings broke the byte-identical round-trip. `eol`
was a single whole-file flag and split(/\r?\n/) discarded each line's
own terminator, so render re-joined with ONE style and normalized every
line — even with zero strips performed. A file with one CRLF line and
the rest LF came back fully converted. That falsified the A14 guarantee,
violated the design's "must not silently rewrite every line", and made
the CONTEXT.md glossary claim wrong. It was untested because A12 and B15
only cover PURE CRLF; no mixed-ending fixture existed anywhere.

Fixed by keeping each line's terminator alongside its content, so render
is a plain concatenation and a strip removes only the target line and
its own terminator. `eol` survives as informational metadata that render
never reads. Seven fixtures added for the paths nothing exercised:
mixed endings unmodified and with a strip, a lone \r, a file ending on
the block's closing ''' with no newline, multiple trailing newlines, a
BOM-only file, and an empty file.

MINOR, but it contradicted this phase's own contract: the write was
in-place open-truncate, so a failure between truncate and completion
leaves a truncated .toml — exactly what ADR-2313 says must never happen.
The Codex path now writes a sibling temp file and renames over the
target, which is atomic on one filesystem, with cleanup on failure. It
uses the repo's existing retryRenameSync rather than a hand-rolled
rename, and deliberately NOT platformWriteSync, whose normalizeContent
would mangle the very CRLF and trailing-newline bytes the round-trip
property exists to preserve.

The Claude path keeps its in-place write untouched. It has the same
shape, but changing it is not this phase's business and its tests must
stay byte-identical.

B20 previously mocked writeFileSync to throw BEFORE touching anything,
so it proved nothing about a mid-write failure — its passing comment was
true only because of how the mock was built. It now performs a real
truncated write wherever writeFileSync is called, catching both the
naive direct-to-target path and the new temp path, and asserts the
target is byte-identical afterwards with no stray temp file left.

* fix(#3243): preserve the trailing-newline state when stripping a last line

Caught by B17, one of this phase's own tests — the suite working, not a
test problem.

Content is reconstructed as the concatenation of lines[k] +
terminators[k], so a file with no trailing newline has '' as its last
terminator. removeLine spliced out both arrays at the same index, which
is right for a middle line but wrong for the last one: it dropped the
empty terminator and left the PREVIOUS line's newline in place. A file
ending `...\nmodel = "sonnet"` with no trailing newline came back
as `...\n`, gaining a newline the user never wrote.

The new last line now inherits the removed line's terminator, so a
removal leaves the file exactly as if that line had never been written.
Removing the only line yields an empty file rather than a stray
terminator.

Both stripModel and stripReasoningEffort funnel through the one
removeLine, confirmed rather than assumed, so a single fix covers both —
including the row-B7 shape where a stale model and its orphaned effort
are removed in sequence and the second removal targets the last line.

Two of the four new cases are honestly not red-first and say so in
their comments: removing a last line that HAS a trailing newline only
exposes the bug under mixed EOL, since uniform files coincidentally
have equal terminators on both sides; and removing the only line
already degenerated correctly through Array.slice. They are kept as
guards for the new branch rather than dressed up as catches.

* docs(#3243): document the codex repair path and close the loop

How-to: the Codex-400 entry added in Phase 2 told users to re-run the
installer, because that was the only repair available then. It now leads
with `effort sync` and keeps the reinstall as the alternative, with the
reason to prefer one — a reinstall regenerates the agent files
wholesale, so anyone who hand-edited theirs loses those edits. Detect,
preview, apply is now one continuous path in one place.

Reference: docs/COMMANDS.md had no `effort sync` entry at all — the same
gap `validate agents` had in Phase 2, found the same way. The entry
documents BOTH runtimes, because the command genuinely forks on runtime
and describing only the new half would misdescribe it.

The write flag is `--apply`. The design doc and test matrix both said
`--no-dry-run` throughout, which does not exist — verified against the
actual arg parser in gsd-tools.cjs before writing. Documenting a flag
that does not exist is worse than documenting nothing, because it fails
at the moment someone needs it.

Both surfaces state that only the targeted lines are removed and every
other byte is preserved. That is a user-visible guarantee rather than an
implementation note: it is the difference between a two-line diff and a
reformatted file in someone's dotfile repo, it is what the IR's
round-trip property exists to deliver, and writing it down makes it a
contract a future change has to break knowingly.

* fix(#3243): inherit the trailing-newline state, not the line ending style

My previous rule was subtly wrong and this phase's own test caught it.

"The new last line inherits the removed line's terminator" copies the
removed line's STYLE as well as its presence. A26 uses mixed endings on
purpose — line one terminated \r\n, the model line terminated \n — so
inheriting silently rewrote line one's ending to \n. That is precisely
the defect class the mixed-EOL blocker fix existed to eliminate,
reintroduced one layer down by the fix for it.

The correct rule inherits the EMPTINESS only. If the removed line had no
terminator, the new last line loses its own, preserving "this file has
no trailing newline". Otherwise the new last line keeps its own
terminator: it is already a newline, and already the right style for
that line.

A26's assertion moved too, and that deserves saying plainly rather than
burying: it previously encoded my wrong rule. Changing a test to match
the implementation is usually the mistake, so it was checked from first
principles instead — a file whose first line ends \r\n and whose last
line ends \n, with that last line removed entirely, must be the first
line with its own \r\n intact. The new expectation is what the user's
file should actually look like; the old one was wrong.

A29 adds the interaction nothing covered: the compounding case (strip a
stale model, then its orphaned effort, the second removal landing on the
last line) with non-uniform endings either side. The two fixes meet
there and nothing exercised the meeting point.

* fix(#3243): drop the phantom trailing line from the IR representation

Root cause, not another patch on the removal rule. Three consecutive
fixes there each surfaced the next issue, which was the signal that the
data model was wrong.

splitPreservingTerminators left a phantom empty final entry for any file
ending in a newline: "a\nb\n" became lines ['a','b','']. So for the
common case the real last content line was NOT the last array element,
removeLine's isLastLine check never matched it, and every rule I gave
was reasoning about the wrong element.

What hid it: render was already a plain concatenation, so a phantom
empty line with an empty terminator contributes nothing to the output.
A14's byte-identical round-trip could never have caught it — the defect
is byte-neutral until a removal shifts the index arithmetic under it.
That is worth recording, because "the round-trip test is green" was
exactly the reassurance that kept the search pointed elsewhere.

The representation is now 1:1 — terminators[i] follows lines[i] and may
be '' — with no phantom, verified across empty, no-trailing-newline,
trailing-newline, blank-line and mixed-CRLF inputs. render stays a plain
concat and needs no special cases. With the phantom gone the removal
rule is correct as stated and finally applies to the genuinely last
element.

Consumers checked rather than assumed: the block-range detector and
header scanner are agnostic to array shape, and Phase 2's reader uses
its own independent split, so tests/agent-install-check.test.cjs is
untouched and still passes unchanged.

One test expectation was wrong and is corrected rather than quietly
adjusted: A18 asserted a 7-element terminators array whose trailing ''
was the phantom itself. It now asserts the six real terminators, which
is what the invariant lines.length === terminators.length requires.

c2f24265f2 feat(#2870): resolve install scope as a value (#3278)
* test(#2870): failing-first suite for the Install Scope Module

19 tests over the 50-test-matrix rows 1-19. RED by construction: the
module under test does not exist yet, so the suite fails at require with
MODULE_NOT_FOUND until src/install-scope.cts lands.

Every row asserts a returned value with injected env/home/existsSync --
no filesystem, per the issue's acceptance criterion that tests assert the
resolved value directly.

Row 7 asserts the RELATION rank(global) > rank(local) rather than a
literal, so Phase 2 (#2871) can re-base the numbers without a fixture
edit. Row 4 iterates the real runtime registry rather than a hardcoded
list, excluding vscode, which declares configHome.kind none and is never
CLI-installed.

* feat(#2870): add the Install Scope Module

Scope becomes one resolved value instead of a bare string re-derived at
every layer. resolveScope({id, runtime, ...}) returns
{id, configHome, settingsFile, consentRequired, hostPrecedenceRank}.

It COMPOSES resolveConfigHomeFromDescriptor rather than extending it.
That function has 60 dependents across 13 files and 2 process flows -- a
CRITICAL blast radius -- so adding a scope parameter to it, which the
issue's framing invites, would ripple through all of them. Composing
costs nothing and leaves every existing caller byte-identical.

The module owns the InstallScope type name, which previously lived
privately in runtime-artifact-install-plan.cts; that module now imports
it. A fifth spelling of the same concept would have defeated the phase.

settingsFile is null for the 18 runtimes that declare no
settingsFileByScope -- absence is a value, not an error, and inventing a
Claude-shaped default would leak that host's shape onto every other one.

hostPrecedenceRank ships unread: Phase 2 (#2871) is its first consumer.
It is carried as data only, per this issue's out-of-scope note that
precedence semantics belong to that phase.

Vocabulary: the install axis standardizes on local. ConsentRecord.scope
keeps project deliberately -- that literal is serialized into consent
records in the user's home, and renaming it would silently deactivate
every project-scoped capability on the machine. CONTEXT.md records the
boundary mapping instead.

Every environmental input is injectable (env, home, existsSync, cwd), so
the resolved value is assertable with no filesystem at all.

Registration ripple: .gitignore, eslint.config.mjs, CONTEXT.md glossary,
docs/INVENTORY.md, and the inventory manifest (regenerated after
build:lib, never before).

Verified via the remote runner.

* refactor(#2870): route scope re-derivations through the module

bin/install.js resolves scope once per function instead of inline at
each of its 12 sites, and the settingsFileByScope consumer reads it
through resolveScope().

Seven downstream boolean re-derivations now call the module's
isGlobalScope() instead of comparing the literal independently:
runtime-artifact-install-plan, both runtime-artifact-layout kind
builders, dispatchKindEntry, surface, and two install-engine sites. The
fifth through seventh were not named in the issue -- they are the same
re-derivation class, and leaving them would have made the acceptance
criterion false.

_computePathPrefix keeps its isGlobal boolean API, so the projection is
centralized rather than eliminated. resolveScope and isGlobalScope share
one validator, so the two surfaces cannot drift.

TWO SITES DELIBERATELY NOT ROUTED: runtime-artifact-conversion's
rewriteStagedSkillBodies and rewriteStagedCommandBodies. ADR-1508 fixes
the direction as installer/layout -> conversion, never upward, and
install-scope composes runtime-homes, so importing it into the
conversion module would invert that direction. Left as-is on purpose.

Behavior-preserving throughout. Each step was proven by capturing full
layout and plan output -- including every kind's home field and the
hashed contents of emitted files -- before and after, across both scopes
for claude, codex, opencode, hermes, kimi and kilo. Byte-identical.

surface.cts keeps a scope ?? 'global' default before the call because
Layout.scope is optional there; isGlobalScope throws where the old
inline compare returned false, and that difference would have been a
placement regression.

Verified via the remote runner.

* fix(#2870): cover the no-config-home throw and document the strictness

Two findings from the isolated adversarial review.

The vscode case was implemented but untested. resolveScope throws for a
runtime whose descriptor declares configHome.kind 'none', which is the
design's own behavior-table row 13, but the registry sweep excluded
vscode rather than asserting the throw -- so the behavior shipped with
no test. The exclusion is now legitimate because the case has its own
test naming the runtime in the assertion.

isGlobalScope throws where the inline compare it replaced returned
false. No reachable caller can deliver an out-of-union value today, but
the types are not enforced at runtime, so a future caller passing an
optional Layout.scope would crash rather than silently misroute. That is
the better failure -- misrouting writes artifacts to the wrong place --
but it was undocumented, so the reason is now on the function.

Adds the changeset the acceptance criteria require.

* refactor(#2870): route the last two sites; correct the ADR-1508 claim

The previous commit declined to route runtime-artifact-conversion's
rewriteStagedSkillBodies and rewriteStagedCommandBodies, claiming
ADR-1508's dependency direction forbade the import. That reasoning was
wrong, and this commit corrects it.

Two independent reviewers checked the actual import graph:
runtime-artifact-conversion already imports capability-registry,
command-roster, runtime-name-policy and shell-command-projection -- it
depends on leaf-tier siblings today. install-scope imports only
runtime-homes plus node builtins, and runtime-homes imports only node
builtins, so there is no cycle at any depth. ADR-1508 governs the
installer/layout to conversion boundary, not a leaf-to-leaf sibling
import of the same shape conversion already makes.

With those two routed, every isGlobal re-derivation in the tree now goes
through one owner and acceptance criterion 1 is fully met rather than
partially. Nine sites, not the four the issue enumerated.

Also from the review:

Tests were falling through to the real process.cwd() at five local-scope
call sites, which contradicts the acceptance criterion that the resolved
value be assertable with no filesystem. Every one now injects a cwd. One
of the five was a site the review had not spotted.

bin/install.js carried two near-identical copies of the guarded
resolveScope block, one in install() and one in uninstall() -- duplicated
scope logic in the phase whose purpose is removing it. Extracted to one
helper, and the new sites use the file's existing ternary idiom rather
than the if/else that replaced it.

Equivalence re-proven across both scopes for claude, codex, opencode,
kilo and hermes, now including the staged skill and command body
rewrites hashed per file, since those decide the literal spec-root path
baked into every emitted artifact. Byte-identical.

Verified via the remote runner.

* fix(#2870): assert configHome portably instead of with a native separator

The windows-latest node24 shard failed on two install-scope assertions.
The module was right and the tests were wrong: they built their expected
value with path.join, which emits \fake\home\.claude on Windows, while
resolveScope normalizes separators unconditionally to /fake/home/.claude.

That unconditional normalization is deliberate -- backslash paths arrive
on Linux too, so normalizing via path.sep is the documented defect this
repo guards against. Weakening it to make the assertion pass would have
inverted the fix.

Every path.join-built expectation in the suite now goes through
toPosixPath from tests/helpers.cjs, which is the pattern the
no-path-literal-in-assert rule's own valid-case list sanctions. It splits
on the running platform's path.sep and rejoins with forward slashes, so
it reverses whatever path.join produced on that same platform and the
expectation is invariant everywhere.

Two more call sites had the same latent problem and passed on Linux and
macOS by luck; they are fixed too.

This is the class of defect the remote runner structurally cannot catch
-- its matrix is Linux-only, so a green pass there is not evidence of
portability, and CI's Windows lane is the only place it surfaces.

Verified via the remote runner.

b901d1e06f feat(#1953): complexity-triggered refactor extension point (execute:post) (#3261)
* test(#1953): failing-first suite for the complexity-triggered refactor hook

60 behavioral cases against src/complexity-trigger.cts, which does not exist yet:
decision-point counting, the comment/literal stripping leak surface, threshold and
jump-delta boundaries at limit-1/limit/limit+1, stable-anchor baseline semantics,
and fs fault injection via mock.method. Two fast-check properties assert that
stripping never manufactures a decision point and that comments and string
literals are score-neutral.

Also registers the refactor-trigger capability manifest (inert until
refactor.trigger_enabled) and regenerates the capability registry and matrix.

Verified RED on the remote runner before any implementation exists.

* feat(#1953): complexity-triggered refactor extension point

Adds the opt-in refactor-trigger capability. After a phase executes, an
execute:post step measures per-function complexity for the files the phase
touched and writes a scoped refactor proposal when a function crosses the
configured threshold or drifts past its recorded anchor.

Design notes worth carrying:

- The signal is computed in-core (decision-point counting over comment- and
  literal-stripped source, Node builtins only) rather than via Memtrace or a
  shelled-out analyzer. The hook fires as a deterministic CLI, not an agent
  with MCP tools, and core takes no external dependencies — this is the only
  option a behavioral test can bind to. The metric sits behind a seam.
- The baseline is a stable anchor, not a rolling value: set on first
  observation, moved only on disposition. A rolling baseline makes the delta
  the single-phase change, so a function creeping +2 per phase never trips a
  delta of 5 and the jump check adds nothing over the absolute threshold.
- Strict mode records an open deviation window in the broken-windows ledger
  rather than declaring its own ship:pre gate. ship.md has no generic ship:pre
  gate dispatch — only two hardcoded branches — so a third gate of any kind
  would be declared and never evaluated.
- The gate clears on the proposal being dispositioned, never on the score
  improving. A blocking complexity number is one an executor can satisfy by
  splitting a coherent function in two.

execute-phase.md gains a generic execute:post step-dispatch contract; it
previously matched only ref.skill == "code-review", so any other step
registered there was declared and never run. The code-review branch is
unchanged.

Full rationale in ADR-1953.

Closes #1953

* fix(#1953): close git option injection and symlink escape in the refactor hook

Three findings from the isolated security review, all fixed inline.

HIGH — changedFilesSince interpolated the --since value into a revision
token placed before the -- separator. A -- only stops PATHSPEC parsing of
arguments after it; git still option-parses what comes before. So
--since '--output=/tmp/x' became --output=/tmp/x..HEAD, which git accepts
as --output=<file> and uses to redirect diff output — an arbitrary write.
Fixed with --end-of-options before the revision range plus a conservative
ref validator. The validator deliberately permits ~ ^ @ { } because those
are legitimate git REVISION syntax (HEAD~1, main@{yesterday}) as distinct
from ref-NAME syntax; --end-of-options is the actual barrier. The doc
comment asserting the trailing -- was sufficient was wrong and is corrected.

MEDIUM — resolveConfinedPath confined by string prefix only, so a symlink
committed inside the repo passed the check (its own path is under cwd) and
readFileSync then followed it outside the root. Now lstat-checks for a
regular file and skips anything else with REFACTOR_FILE_UNREADABLE, so one
bad path skips one file and the run continues.

LOW — the new execute:post dispatch contract showed the gsd_run example
before the rule requiring ref.command be validated first. That prose is
executed by an agent, so textual order is execution order. Reordered.

Refs #1953

* fix(#1953): make the analyzer able to see TypeScript at all

Found by running the shipped analyzer over its own source: it reported
functions=1 for a 940-line module with 24 function forms. A return-type
annotation or a generic parameter list made a function invisible —
`function f(a): number {}` and `function f<T>(a: T): T {}` both detected as
zero. Since gsd-core is written in .cts and the capability declares
.ts/.cts/.mts analyzable, the feature silently found nothing in this repo's
own primary language while reporting success. A safety net that reports
"all clear" because it cannot see is worse than no safety net.

All 98 tests passed over this, because every fixture was plain JS — the
exact failure the test matrix's own "assert against the shape production
uses" warning describes. Adds a TypeScript-shapes suite covering return
types (including unions, generics, object literals and type predicates),
generic parameter lists (constrained and defaulted), export/async/generator
combinations, annotated arrows, class-method modifiers, and optional/
default/rest params — plus the two traps: an overload signature has no body
and must not count, and `a < b && c > d` is a comparison, not a generic.
Detection now reports 24/37/21 functions for the three source files, which
matches a hand count exactly.

Also from review:

- The strict-mode ledger dedup identified entries by parsing a prose
  description string. That is banned by CONTRIBUTING's raw-text-matching
  rule and was a real bug: the "exactly one window per untriaged proposal"
  guarantee rested on prose matching, so rewording a description or editing
  WINDOWS.md by hand silently produced duplicates. Now matches structurally
  on kind + phase + file + line.
- A property test asserted on the stripper's output text. Reframed to
  assert the same invariant through analyzeSource's score.
- nextBaseline's `candidates` parameter has been dead since the anchor
  change; removed from the signature and all call sites.
- Extracted the duplicated require-or-degrade and capability-check
  boilerplate.
- ADR-1953's Implementation bullet still named a `refactor.ship-gate` in
  check-command-router.cts — a leftover from the design cut D6 rejects.
  That file is untouched and no such gate exists. Removed.

Refs #1953

* fix(#1953): keep execute-phase.md under its byte ceiling; un-vacuum the large-file test

Five of the seven remote-runner failures were one cause: the execute:post
dispatch contract, written out inline, grew execute-phase.md 1876 bytes
(93,400 -> 95,276) against a frozen PRE_PHASE6 ceiling of 93,600. A drift-ack
does not clear that — tests/phase6-capstone-conformance.test.cjs and
tests/fix-2285-claude-orchestration-wiring.test.cjs assert the file is
literally under the cap.

The contract now lives in gsd-core/references/loop-hook-dispatch.md, which
already claimed to be the point-agnostic dispatch reference and already
documented ref.skill and ref.agent. It gains the ref.command shape, its
in-context validation rule, the advisory-by-construction statement, and a
note that a point whose workflow hand-rolls one kind is not implementing
this contract. execute-phase.md now defers to it in one line: 145 bytes of
growth, 55 B of headroom under the cap. Better placement than the first cut
— the reference was overstating its coverage, and this makes the claim true
rather than duplicating prose next to it.

Acknowledged by appending to tests/emitted-drift-acks/2930-*.json rather
than a new 1953-*.json: two ack sources may never name the same path, and
that fragment is already the accumulating ack for this file.

Sixth and seventh failures: analyzesLargeFileWithinBounds tripped its own
vacuity guard — the fixture generated ~480 KB against a `> 500000` assert,
so the guard fired and the three assertions after it never ran. The test
has been vacuous since it was written. The matrix row specifies ~1 MB, so
N goes 8000 -> 20000 (1.17 MB, 17% margin) and the guard to > 1_000_000.
Verified by reproducing the exact body against the compiled module: 1168888
bytes, 118 ms, all four assertions hold.

Refs #1953

* fix(#1953): fold the execute:post step deferral into the existing resolve line

The remaining two failures were one test: execute-phase.md carries a SECOND,
tighter assertion than the 93,600 ceiling — `<=93400`, which is exactly its
current size. The file cannot grow by a single byte. My previous fix got it
under 93,600 but not under 93,400, so it still failed. ("H." in the report is
just the parent describe of that same test, not a separate defect.)

Rather than add a paragraph, the deferral now REPLACES the existing hook
resolution line. It read:

  Resolve active step hooks from `EXECUTE_POST_HOOKS_JSON` where
  `kind == "step"` and `ref.skill == "code-review"`.

which is the bug itself written down — only code-review was ever dispatched.
It now reads:

  Dispatch each `kind == "step"` hook per
  @gsd-core/references/loop-hook-dispatch.md. For `code-review`:

The following prose already begins "If no active code-review step hook
exists", so it reads correctly and the code-review handling is untouched.
Net effect on the file is -11 bytes: 93,400 -> 93,389, under the margin
assertion rather than merely under the ceiling.

That also removes the need for a drift-ack: the file shrank, so there is no
growth to acknowledge, and the append to the shared 2930-*.json fragment is
reverted. Leaving it would have shipped a claim of "145 bytes of growth"
that is no longer true, on a file six other issues share.

The test's own comment states the principle this ended up honoring: "the host
loop must stay small — optional-feature detail belongs in the capability
fragment, not the host workflow." Putting the dispatch contract in the
reference rather than inline is that rule, applied.

Refs #1953

* fix(#1953): keep the code-review hook literal the workflow test requires

tests/code-review.test.cjs extracts the <step name="code_review_gate"> block
and asserts it contains `ref.skill == "code-review"` verbatim. The previous
commit replaced the line carrying that literal, so the token vanished and the
test went red — a fair assertion: code-review IS the bespoke branch there and
the workflow should still name it.

Restored inside the same one-line deferral, which now reads:

  Dispatch `kind == "step"` hooks per @gsd-core/references/loop-hook-dispatch.md.
  `ref.skill == "code-review"`:

93,396 bytes — still under the `<=93400` margin assertion and 4 bytes below
the base, so the file continues to shrink rather than grow.

Because three consecutive runs were each reddened by a different assertion on
this one file, this change was verified by sweeping ALL of them at once rather
than one run at a time: every test under tests/ that reads execute-phase.md or
references/loop-hook-dispatch.md was located by resolving its path constants,
and each content/size assertion was evaluated directly against the working
tree — 22 assertions, plus two real executions (gen-section-manifest --check,
and emitted-attribution's full real-tree differential). All pass.

That sweep also confirms the earlier judgement call: the net change to
execute-phase.md is a SHRINK, and the size ratchet only gates growth, so
reverting the append to the shared 2930-*.json ack fragment was correct — an
ack would have been both unnecessary and factually wrong.

* chore(#1953): backfill changeset pr number to 3261

* docs(#1953): add the missing how-to for acting on a refactor proposal

Reference and explanation shipped (COMMANDS.md, CONFIGURATION.md,
FEATURES.md 159, ADR-1953) but the Diataxis how-to quadrant did not, and
that is the one a user reaches for. CONTRIBUTING's required-docs table is
'new command -> COMMANDS.md + FEATURES.md', so CI was green on a gap.

Enabling this feature is genuinely multi-step and no single page walked it:
turn it on, tune the threshold, understand advisory vs strict, discover
that strict needs a SECOND toggle on a DIFFERENT capability, and know what
to do when a proposal appears. The two-toggle subtlety in particular was a
footnote in a config table; here it is a section with both commands.

Follows the shape of its closest siblings, resolve-edge-coverage-findings
and resolve-prohibition-findings — both 'the loop surfaced a finding, here
is what to do with it'. Includes a reason-code table for the silent cases,
since the analyzer is deliberately quiet in six situations and a user who
expected a proposal needs to tell 'nothing to report' from 'could not look'.

Indexed from docs/README.md beside the other loop how-tos.

Docs-only: exempt from the push gate, no re-verification, pass marker on
2af188b4 untouched.

Refs #1953

* feat(#1953): warn when strict mode is on but nothing will actually block

Closes acceptance criterion 5, which I had wrongly marked satisfied.

refactor.trigger_strict records an untriaged proposal as an open deviation
window, but a ship only STOPS if workflow.windows_enforce is also on — a
toggle owned by the broken-windows capability that this feature neither sets
nor requires. So a user could enable strict, believe ship was gated, and find
out otherwise at ship time.

The split itself stays: requires:["broken-windows"] would force-install the
ledger on advisory users who never enable strict, and a ship:pre gate of our
own would never fire because ship.md has no generic ship:pre gate dispatch.
What was missing was discoverability, so that is what this fixes.

`refactor evaluate` now emits a typed REFACTOR_STRICT_NOT_ENFORCING warning,
naming the exact remediation command, whenever strict is on and either
workflow.windows_enforce is off or broken-windows is unavailable. It fires
only on a run that produced a candidate — with nothing to block on there is
nothing to warn about, and warning every run would be noise.

Reads workflow.windows_enforce through the same resolveConfigKey walk the
router already uses for its own keys rather than a second config reader.
Four tests cover the matrix: strict+enforce-off warns, strict+enforce-on does
not, strict+ledger-absent warns, strict-off never warns.

Also corrects a user-facing message in this same file that told the user to
run `gsd-tools config-set` — the wrong form. docs/CONFIGURATION.md and the
broken-windows capability both use `gsd config-set`, and gsd-tools is invoked
as `node gsd-tools.cjs`, so the bare form may not resolve. The two adjacent
messages in this file now agree.

343835facc refactor(#3183): route live-plan counting through scanPhasePlans (#3199)
* refactor(#3183): route live-plan counting through scanPhasePlans

scanPhasePlans becomes the sole owner of the live-plan derivation. Twenty-one
independent re-derivations across seven modules now route through it, and
scripts/lint-plan-count-drift.cjs reports zero, scanning the whole repo rather
than an allowlist (ADR-3180 Decision 4a).

The epic scoped this at three copies. A whole-repo guard found twenty-six sites
across nine files, so Phase 1 absorbs every live-plan re-derivation and Phase 3
narrows to window plus sentinel enumeration.

Two sites are exempt with a documented reason rather than a bare allowlist:
audit.cts scans one quick task's own directory for a single completion record,
and gsd2-import.cts reads a foreign GSD-2 tasks/ layout during a one-time
import. Neither is a phase directory.

scanPhasePlans gains allPlanFiles (pre-supersession) alongside planFiles so one
owner answers both questions: verify.cts's numbering-gap check wants every plan
on disk, its pairing check wants the live set. Both fields are additive.

Highest-severity fix: cmdPhasePlanIndex, which feeds execute-phase wave
scheduling, was scheduling status:superseded plans into waves and reporting zero
plans for the post-#3139 nested layout.

filterPlanFiles and filterSummaryFiles are deleted; getPhaseFileStats orphaned
them and only their own tests still called them.

New leaf module src/planning-scope.cts carries the frozen SCOPE discriminator,
with its six-gate ripple closed: gitignore, inventory manifest, INVENTORY.md and
the CONTEXT.md glossary.

The contract held; the phase boundary did not. The whole-repo drift guard found
26 re-derivations across 9 files against the epic's estimate of 3, and
cmdProgressRender re-derives both enumeration and plan counting on adjacent
lines, so DW4 was unsatisfiable within Phase 1's original file scope.

Records the amended scope, scanPhasePlans's new allPlanFiles field,
findOrphanSummaries, the two documented exemptions, the re-derived Tier-2
table, and the describeNonCanonicalPlans trap for later phases.

* fix(#3183): complete the canonical pairing rule and gate the naming diagnostic

The remote runner went red with 13 deterministic failures on both lanes,
and they were right: replacing verify.cts's canonicalPlanStem pairing with
summaryCandidates dropped a case the bespoke rule covered. A plan carrying a
descriptive slug after its id (68-01-scaffolding-PLAN.md) pairs with its
canonical-stem summary (68-01-SUMMARY.md), and summaryCandidates generated no
such candidate, so the plan read unsummarized.

The fix is to complete the one rule rather than restore a second:
summaryCandidates gains a canonical-id candidate, narrowed to fire only when an
id pair was actually extracted. countMatchedSummaries, findUnsummarizedPlans
and findOrphanSummaries all inherit it. The two-plans-one-summary collision
behaviour of the original rule is preserved deliberately and documented in
place.

Second defect, independently root-caused while verifying: routing the #2893
naming diagnostic through scanPhasePlans exposed it to the loose /PLAN/i
fallback, which is correct for counting and wrong for a naming check — a
non-canonically-named file was accepted as a valid plan and the diagnostic
went silent. cmdPhasesList, cmdFindPhase and cmdPhasePlanIndex now intersect
with a strict isCanonicalPlanFile predicate before reporting names.

Same class as the describeNonCanonicalPlans trap already recorded in ADR-3180:
a question about file naming wants the physical, strictly-matched set; only a
question about outstanding work wants the live set.

five of the six .cts ripple gates - gitignore, inventory manifest, INVENTORY.md
and the CONTEXT.md glossary - but not eslint, because that one is enforced by a

* fix(#3183): replace the plan-count drift detector with a literal tokenizer

CodeQL reported 4 high-severity js/redos alerts on REGEX_LITERAL_MD_RE, the
backtracking regex that finds "a regex literal mentioning PLAN/SUMMARY and an
escaped \.md". Five review rounds found it had two defects, not one:

  - EXPONENTIAL, then CUBIC. Its "any char" atom `(?:\\.|[^/\r\n])` let a `\.`
    pair be consumed either as one escape or as two class characters, which is
    exponential backtracking: 27,464ms on `"/\.mdplan" + "\.".repeat(28) + "X"`.
    Excluding `\` from the class killed that but left a cubic path — 23ms at
    N=200, 172ms at N=400, 1362ms at N=800 on `"/" + "PLAN\.md".repeat(N)` with
    no closing `/`. This guard is the last stage of `npm run lint:ci`, which CI
    runs on fork pull requests, so a crafted src/*.cts could stall the job.
  - A DETECTION HOLE. A character class holding a bare, unescaped `/` — e.g.
    `/SUMMARY[^/]*\.md$/`, an ordinary path-excluding filter — terminated the
    literal at that `/`, so the scan never reached `\.md` and the guard missed
    it entirely. (Classes holding an ESCAPED `\/` were already matched; the
    tests cover those separately as parity, not as regressions.)

Both defects have one root cause: regex-literal grammar — `\x` escapes, and
`/` inside `[...]` not terminating — is not expressible in a backtracking
regex. So the detector is now a tokenizer, not a regex.

readRegexLiteralAt reads the literal at a given `/` in a single left-to-right
pass with no backtracking, treating escapes as two-character units and
suppressing the `/` terminator inside a character class. findRegexLiteralMdMatch
restarts it at every `/` on the line, preserving the old "find anywhere"
behaviour; MAX_REGEX_LITERAL_LEN (400) bounds each read — including the
trailing-flag scan — which keeps the whole-line cost linear.

Results: cubic shape flat at 0.06-0.39ms out to N=3200 (25KB), exponential
shape 0.01ms at 28 reps and 0.00ms at 64, and the bare-`/` class shapes are now
caught. Differential against the old regex over 28,474 lines (those matching
FILENAME_TEST_RE but not PLAN_SUMMARY_LITERAL_RE, across src/tests/scripts/
gsd-core/bin/eslint-rules, excluding 265 lines with >6 backslashes on which the
old regex hangs): 6 differences, all the tokenizer returning the fuller or
newly-correct literal, 0 old-only misses. The `\.md` token stays
case-insensitive, matching the `/i` the old regex carried.

Also closes three holes in the same new file:

  - walk() tested entry.isFile(), false for a symlink, so a symlinked
    src/*.cts was silently unscanned — an evasion of a guard whose stated
    principle (ADR-3180 Decision 4a) is whole-repo discovery with no allowlist.
    It now resolves symlinks, but confined: file links must resolve inside the
    repo root, directory links inside the scanned dir itself. Every sibling
    drift guard in scripts/ uses the Dirent classification and never follows
    links, so following them unconfined would have made this the only linter
    able to read outside the tree — on fork PRs an arbitrary out-of-repo read
    whose matched fragments reach a public CI log. The narrower directory rule
    additionally stops `src/up -> ..` from sweeping the whole repo, and the
    skip list is now checked against resolved paths so `src/g -> ../.git`
    cannot reach .git/** or node_modules/**. Real paths are de-duplicated and
    files reported canonically, so a symlink alias cannot shift which
    FUNCTION_SCOPED_EXEMPTIONS key applies.
  - Both the reported fragment and the reported FILE PATH are attacker-
    controlled source text written straight to a CI log, and git permits
    control bytes in a filename. Both are now escaped — C0/C1/DEL plus the
    bidi and zero-width controls — so a crafted literal or filename cannot
    recolour the log, overwrite a line with CR, or fabricate a line that looks
    like this guard's own success output.

Regression coverage in tests/plan-count-single-owner.test.cjs: a child-process
probe over both pathological shapes (catastrophic backtracking is synchronous
and would freeze the suite rather than fail one test), the bare-`/` class
shapes verified to fail against the parent-commit blob, root-confinement tests
covering the outside-file, outside-directory, cycle, broken-link and duplicate
cases, direct isInsideRoot coverage including the sibling-prefix case that a
bare startsWith would let through, sanitizeForReport coverage, and
limit-1/limit/limit+1 coverage of MAX_REGEX_LITERAL_LEN derived from the
exported constant. The earlier structural assertion was dropped — it checked
for the substring `[^/`, which respelling the class as `[^\r\n/]` defeats
while staying exponential.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

da062c0e0d chore(#2996): inventory the workflow fragment tree as its own manifest families (#3061)
* feat(#2996): inventory the workflow fragment tree as its own families

Epic #1671 Phase 6.5, the epic's last deliverable.

47 step files across 15 workflows and 13 mode files were invisible to
docs/INVENTORY-MANIFEST.json. Not through a missed row — through construction:
buildManifest walks each family with a flat readdirSync + isFile() and never
recurses, so nothing under gsd-core/workflows/<wf>/ could ever appear. modes/
has been invisible that way since #717 without any gate firing, which is the
evidence that this is a generator gap rather than someone forgetting a row.

Two new families, workflow_steps and workflow_modes, keyed by
<workflow>/<subdir>/<file> rather than a bare basename. That is deliberate: two
workflows may each own a regression-gate.md, and a step file may share a name
with a top-level workflow. The manifest is compared by JSON equality, so a
basename collision would silently drop an entry and read as "up to date".
Recursion is bounded at exactly one named subdirectory, and a limit+1 test pins
that bound so it cannot quietly become a general walk.

tests/inventory-manifest-sync.test.cjs carried its OWN duplicate copy of the
FAMILIES table — the DEFECT.GENERATIVE-FIX divergence class. Adding a family to
the generator alone would have left that test verifying six of eight families
while still reporting green. The table now lives once in the generator and is
imported, so the two surfaces cannot drift; runMain is guarded behind
require.main so importing does not execute the CLI.

The per-file roster stays in the generated manifest rather than being copied
into INVENTORY.md: 60 hand-maintained rows in lockstep with a generated artifact
is precisely the drift this file exists to catch.

CONTEXT.md's RULESET.MANIFEST-CANONICAL-KEY and DEFECT.INVENTORY-DRIFT both said
"six families" and now say eight, with the two key shapes and the import rule
recorded. The non-shipping example index was regenerated for the same edits.

Note on scope: this issue also asked for a one-fragment-edit proof. That landed
independently as PR #3046 and is not rebuilt here.

* fix(#2996): correct a fabricated roster and an inert coverage pragma

Isolated review returned one blocker and three lesser findings. All four were

BLOCKER — docs/INVENTORY.md claimed the workflow_modes roster was
"discuss-phase, sketch". There is no gsd-core/workflows/sketch/ and never has
been; the second member is `help` (4 mode files), exactly as the manifest
generated by this same diff already listed. A doc contradicting the manifest it
describes, in the PR whose whole purpose is closing doc/reality drift. The
adjacent hand-maintained "15 workflows" count is also removed: an unenforced
number in a table cell is the same staleness class this file exists to catch,
and no test guards table-cell counts.

MAJOR — the CLI entry guard carried `/* istanbul ignore next */`, which excludes
nothing here. This repo measures coverage with c8 (test:coverage:scripts-floor,
55% floor over scripts/**/*.cjs), and c8/v8-to-istanbul honors only
`/* c8 ignore next */`. The pragma looked like it was doing something and was
not — the same failure shape as a marker that looks like working gating.

MINOR — collectNested called statSync/readdirSync unguarded, so a dangling
symlink or an EACCES directory under any workflow's steps/ would throw uncaught
and red the manifest gate for the entire repo. An entry that cannot be statted
is, for inventory purposes, not a countable file — the same disposition as "not
a directory". Row 13c pins the behavior with a real dangling symlink.

* chore(#2996): backfill changeset pr number to 3061

* test(#2996): guard the dangling-symlink row on Windows

fs.symlinkSync throws EPERM on Windows without elevation or Developer Mode, so
row 13c would red the Windows lane. Guarded with the repo's idiom — a
process.platform check plus a genuine t.skip() carrying its reason, never a bare
return, which node:test counts as a PASS and would hide the gap.

Worth recording why this was not caught here: CI classified this PR's diff as
inert (no bin/, gsd-core/, or src/ changes), so the full test matrix was SKIPPED
entirely — the 'full test (${{ matrix.os }}, ...)' job shows as skipping with
its matrix expression unexpanded. The Windows lane never ran. It would have
fired on the next PR that does touch core code, in someone else's change.

ed360cd99f chore(#2995): extend fragment emission to agents/ and reclaim size-cap headroom (#3058)
* feat(#2995): extend fragment emission to agents/ across every read point

Epic #1671 Phase 6.4. `composeWorkflow` stripped `<!-- gsd:section -->` markers
only for `gsd-core/workflows/`, so a marked agent shipped its markers verbatim
into every runtime — and agent text is loaded into a subagent's context on every
dispatch.

The issue proposed widening the `copyWithPathReplacement` guard. That is a no-op
for agents: agents never traverse that function. Agent content is read for
emission at five independent points, and the obvious chokepoint
`stageAgentsForProfile` short-circuits on the DEFAULT `full` profile
(`skills === '*'` returns the real unstaged directory), so a hook placed there is
dead code on most installs.

Composition now happens at two call sites instead of five parallel surfaces:
`stageAgentsForRuntimeWithConverter` (with `agentsKind` and `kimiAgentsKind`
routed through it via an identity converter) and the inline agent loop in
bin/install.js. Both compose BEFORE any path rewrite, so a `.claude/` ->
`.windsurf/` regex can never reach inside a marker attribute — the ordering
#2930 established for workflows.

`installCodexConfig` was the fifth read point: Codex embeds each agent's prompt
into a per-agent `.toml` via its own readFileSync. Call-graph analysis missed it;
the exhaustive per-runtime emission sweep found it. That is why the new guard is
behavioral rather than structural — a sixth read point fails the sweep without
anyone remembering to extend a list.

tests/agent-fragments-emission.install.test.cjs spawns a real installer for every
runtime at every agent-bearing scope, derived from RUNTIME_META and the
capability registry at run time so a new runtime cannot be silently
under-covered. It asserts markers are absent AND the `when="always"` body is
retained, so marker-absence cannot be satisfied by dropping content. An
identity-composer negative control proves the assertion can fail.

Verified: 0 install failures, 0 marker leaks, body retained on 27 runtime/scope
paths; red before the wiring on claude(global+local), zcode(global+local),
kimi, codex and opencode.

* chore(#2995): give the tightest agents headroom and correct the design lock

Epic #1671 Phase 6.4, second half.

`agents/gsd-verifier.md` had 12 bytes of headroom under its 49,152-byte LARGE
cap and `agents/gsd-debugger.md` had 147 under its 57,344-byte XL cap. Both now
extract reference material to `gsd-core/references/` behind an @-reference — the
documented DEFECT.AGENT-FILE-SIZE-CAP-BREACH remedy:

  gsd-verifier  49,140 -> 46,371 B   headroom    12 -> 2,781
  gsd-debugger  57,197 -> 48,851 B   headroom   147 -> 8,493

Byte accounting proves no content was lost: the combined agent+reference delta
is exactly the new files' headers plus the agents' slim replacement blocks. Each
agent keeps its routing table and a one-line summary per entry, so it degrades
gracefully on a runtime that does not inline @-references.

`agents/gsd-planner.md` is untouched and still passes both char guards
(49,130 < 49,152); it needed no change, so it took none.

The other nine LARGE/XL agents carry NO gsd:section markers, and that is
deliberate, not deferred. `when=` selection is read from
gsd-core/workflows/section-manifest.json, which gen-section-manifest.cjs derives
from gsd-core/workflows/*.md only — shape `{workflows: ...}`, no per-agent key,
no per-agent init entry point. An agent atom therefore fails admission gate (2)
("a fact the init seam demonstrably computes at a real entry point") and would
evaluate false forever while looking like working gating. Marking agents would
manufacture exactly the silent-inertness rot the frozen vocabulary exists to
prevent.

ADR-1671 gains three amendments, two of which close gaps /adr-phase-coverage
found against what actually merged:

  - The 19 -> 29 vocabulary widening shipped in #2994 with no coordinated ADR
    amendment, which that bullet's own rule forbids. Recorded now.
  - `flag:--verify-only` was one of six atoms #2992 withheld and deferred to
    "the LARGE/XL rollout phase". Five shipped; this one is permanently
    rejected, and that disposition lived only in a merged PR body.
  - Phase 6.4's own finding: emission extends to agents/, gating does not.

CONTEXT.md's glossary was stale on both seams — Workflow Fragments Module still
listed the original 4-atom vocabulary and described when= as "not yet acted on",
and Section Manifest Module still described InvocationFacts as
{waveFlag, phaseNumber, hasPriorPhases}. Both now match the shipped contract.

Inventory manifest regenerated AFTER build:lib per the documented ordering
landmine; 19 install-tree fixtures pick up the two new references.

Refs #2995

* chore(#2995): correct the compose-site count and mark the raw stager

Self-review found two comment defects in the prior commit. The agentsKind
comment claimed composition lands at TWO call sites; it is three, since
installCodexConfig's per-agent .toml writer was added after that comment was
written. And stageAgentsForProfile is now production-dead — both callers route
through the composing stager — while staying exported and unit-tested, which
makes it a trap: it does a raw copyFileSync and short-circuits to the unstaged
source directory under the default profile, so a future caller would silently
reintroduce the marker-shipping path. Its JSDoc now says so.

* test(#2995): guard the marker-documenting-doc class for agents

Widening the composer's scope to agents/ makes reachable the exact class #2930
narrowed scope to avoid: a file that DOCUMENTS the marker syntax with an
unfenced example is indistinguishable from a real marker, so the composer drops
that line from the emitted artifact.

Three rows. A fenced example must compose byte-identically. No shipped agent may
carry a marker outside a fence — asserted by parsing every real agent and
requiring zero explicit sections, which is what makes the fence protection
load-bearing rather than decorative. And a non-vacuity row asserts an UNFENCED
marker IS parsed as a real marker, so if that ever stops being true the second
row is guarding nothing.

Also applies two review findings: stageAgentsForProfile's new JSDoc claimed it
had no production caller, which is false — bin/install.js's _stageAgents still
calls it, and its consumers compose before writing. Corrected to state the
invariant instead. And a let/const nit in the emission sweep.

* fix(#2995): keep verifier status vocabulary in the agent, fix a wrong fixture

The first remote run came back red with three failures. Both root causes were
mine.

1. tests/agent-frontmatter.test.cjs requires agents/gsd-verifier.md to literally
   contain HOLLOW and DISCONNECTED. The Step 4b extraction moved that status
   vocabulary into gsd-core/references/verifier-wiring-patterns.md, so the agent
   no longer had it.

   Byte accounting said no content was lost, and byte-wise that was true — but a
   contract required those tokens to live IN THE AGENT. That is ADR-1671:66's
   flexReserve floor stated concretely: a load-bearing fragment must not be
   trimmed out of its host, and "the bytes still exist somewhere" is not the
   test. The two status tables are restored to the agent and deliberately
   mirrored in the reference with a note saying so, so the procedure there still
   reads standalone. gsd-verifier lands at 47,069 B — headroom 12 -> 2,083,
   rather than the 2,781 the first attempt claimed.

2. Row 12b of the new marker-documentation guard asserted that an unfenced
   marker example parses as a real marker, and threw instead:
   "unmatched /gsd:section close marker". The grammar is WHOLE-LINE only. The
   fixture had put the OPEN marker inline mid-sentence, so it was correctly not
   recognised as an open while the close, on its own line, was.

   That is a real refinement of the hazard this guard exists for: only a marker
   on its OWN line is mis-parsed — which is exactly how a documentation example
   is normally written. Row 12b now uses a whole-line marker, and a new row 12c
   pins the inline case as explicitly NOT a marker.

No test was weakened to accommodate the change; the change was corrected to
satisfy the tests.
