dd4f179672 feat(#3970): per-task external-tracker content-resolution seam (#4000)
* feat(#3970): per-task external-tracker content-resolution seam

Implements ADR-3646 (Phase 1, #3970): a `<task tracker-id="...">` attribute
plus a new optional `taskContentResolver` capability-manifest field let a
capability resolve a task's action/verify/acceptance-criteria/read_first/done
content from an external issue tracker instead of PLAN.md's inline body.

- src/plan-document.cts: parses the `tracker-id` attribute into `PlanTask.trackerId`
- src/task-content-resolution.cts: new leaf module — split/find/build/resolve,
  with a hard-halt (throw) contract on ambiguous/failed/timeout/malformed
  resolution, never a silent fallback to possibly-stale inline text
- src/task-command-router.cts: new `task resolve-content --plan --task-id --raw`
  CLI verb wiring the module into a real process exit code
- gsd-core/bin/lib/capability-validator.cjs: validates the new
  `taskContentResolver` manifest field (feature-role only, cross-capability
  trackerPrefix uniqueness)
- gsd-core/workflows/execute-plan.md, gsd-core/references/loop-hook-dispatch.md,
  docs/reference/capability-manifest.md: wire the seam into the per-task loop
  and document it as a new `execute:task` point outside the existing
  contribution/step/gate vocabulary (unconditional in autonomous mode)

Closes #3970

* fix(#3970): gate checkpoint tasks out of content resolution, close trackerPrefix grammar parity gap, cover path-traversal guard

Standards/Spec code-review pass on the task-content-resolution seam (ADR-3646
Phase 1) found three defects:

1. execute-plan.md's task-content-resolution bullet fired on any
   tracker-id-bearing task with no check that it wasn't type="checkpoint:*",
   contradicting ADR-3646 Decision 1 (a checkpoint task must never enter
   resolve-content). plan-document.cts already parses trackerId: null
   unconditionally for checkpoint tasks; only the workflow prose needed the
   fix, so the bullet now explicitly excludes checkpoint tasks.

2. task-content-resolution.cts's parseResolverDeclaration accepted any
   non-empty trackerPrefix with no grammar check, while capability-
   validator.cjs's KEBAB_RE enforces kebab-case at install time — a
   Generative Fix Divergence gap. Added the same grammar (as a literal
   regex, documented as intentionally not shared across the .cts/.cjs build
   boundary) plus a parity test asserting the two surfaces agree across a
   valid/invalid trackerPrefix table.

3. task-command-router.cts's routeResolveContent path-traversal guard on
   --plan had zero test coverage. Added a test exercising a
   ../../../etc/passwit-shaped path and asserting the USAGE rejection names
   the offending path.

* fix(#3970): sanitize resolver diagnostics and cap resolver timeoutMs

Two findings caught by an isolated security-review pass on the task
content resolution seam:

- ResolverFailedError/ResolverMalformedOutputError embedded raw,
  unsanitized subprocess stderr/stdout (attacker/model-influenced via
  the tracker-id argv token) into .message. A hostile or buggy resolver
  could smuggle a newline plus a forged "Error: " line, or terminal
  escape sequences, into a diagnostic io.cjs's error() writes verbatim
  to stderr. Fixed at the constructor (task-content-resolution.cts) via
  io.cjs's existing formatDiagnosticToken(), so every caller of
  resolveTaskContent gets a safe .message by construction.

- capability-validator.cjs's validateTaskContentResolverFields had no
  upper bound on taskContentResolver.invoke.timeoutMs, letting a
  manifest declare an effectively unbounded value and defeat the
  "bounded subprocess" design intent. Added a 120000ms ceiling specific
  to this field, without touching the shared isPositiveIntegerMs()
  helper (still used unbounded by the reviewer lane's timeoutFloorMs
  and probe timeoutMs).

* fix(#3970): fix gsd-test failures — stale prose allowlist line and stderr-vs-message assertion

gsd-test (remote dockerized matrix) came back red with 5 failures on this
PR; all five are real defects, fixed here.

- tests/no-bare-gsd-tools-command-position.test.cjs: PROSE_ALLOWLIST's
  execute-plan.md entry pointed at line 415, which ffc190df4's
  checkpoint-exclusion caveat (added near line 221) shifted down by one
  line. The actual "validated downstream by gsd-tools uat
  classify-coverage" descriptive mention now sits at line 416. Updated
  the allowlist entry's line number to match.

- tests/task-command-router-resolve-content.test.cjs: the path-traversal
  test asserted the outside-project-scope diagnostic against the thrown
  ExitError's own .message. io.cts's error() (ADR-3889) writes its
  human-readable message to fd 2 via writeAllSync and then throws a bare
  `new ExitError(1)` with no message argument — by design, so the
  exception carries no duplicate text and the thrown ExitError's message
  defaults to "process exit 1" (cli-exit.cts's ExitError constructor).
  Root cause was the test, not the source: task-command-router.cjs's
  outside-project-scope rejection already calls error() correctly and the
  diagnostic text is genuinely emitted, just on fd 2, not on the
  exception. Fixed the test to capture fd-2 writes (mirroring
  tests/estimate-calibrate.test.cjs's runCalibrateExpectError and this
  same file's own captureStdout for fd 1) and assert against the captured
  stderr text instead of err.message. This was masked locally because a
  manual `node -e` sanity check that only inspects the caught exception's
  .message cannot see what the real node:test run actually failed on.

Emitted-Drift-Ack-Growth: execute-plan.md — adds the ADR-3646 task-content-resolution bullet and checkpoint-exclusion caveat to the per-task execute loop; a real behavioral prose addition, not incidental bloat.

3a6c0412a9 enhance(#3624): local/no-exact-case-env-access — ratchet ADR-1703 onto production env reads (epic #3411 Phase 4) (#3976)
* enhance(#3624): local/no-exact-case-env-access — ratchet ADR-1703 onto production env reads (epic #3411 Phase 4)

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

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

Closes #3624

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

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

d98b55562c enhance(#3910): the raw terminator is banned by construction (#3980)
* enhance(#3910): move the last src/ terminators onto the seam

Phase 6 bans the raw terminator by construction, which it cannot do while
violations stand. A census found 12 sites the rule would flag; nine of the ten
unsanctioned ones were owned by no phase of the epic at all — a coverage hole
in the decomposition, since P0-P2 are infra, P3 the gate modules, P4 the
scanners, P5 the fragments, P7 the hooks, P8 io.cts, and P6 itself only adds
the rule. `src/**/*.cts` now holds exactly 2 raw exits, both inside
`terminateNow`, the single sanctioned site.

`io.cts`'s `error()` is the interesting one. It was first called substantive on
"dozens of callers, contract risk" — asserted, not measured, and the
measurement refuted it: 289 call sites, zero inside a try whose catch would
swallow a throw. The real obstacle was structural instead: `terminateNow`
cannot emit exit 1, because ADR-3889 §1 makes 0 and 1 unallocatable and
`nameForExitCode(1)` throws. So the only route is `ExitError` under `runMain`,
which sets exitCode and writes stderr only when the error carries a user
message — keeping the existing stderr write and throwing a message-less
ExitError is observably identical.

That census was still too narrow, and running the CLI proved it. It asked
whether the CALL sits in a try/catch; the two regressions that surfaced were
interceptors elsewhere on the stack:

- `command-routing-hub.cts`'s `dispatch()` swallowed the ExitError into a
  HandlerFailure, so the caller emitted a duplicated, wrong stderr line on
  every Hub-routed path. It now rethrows ExitError explicitly — the same shape
  `gsd-tools.cjs` already used at two dispatch sites, so this follows an
  established idiom rather than inventing one.
- the profile-pipeline router's deliberately un-awaited `.catch(e => error(...))`
  turned an ExitError rejection into an uncaught exception; it now mirrors
  runMain's handling.

`edge-probe` and `ui-consideration-probe` gained `runMain` wrappers because
probe-core's new throwing default would otherwise have escaped them.

A follow-up sweep of every dispatcher — 19 command routers, the Hub, the
gsd-tools dispatch seams — found no further swallowing catch. The admitted
bound: ~1260 non-rethrowing catches repo-wide were scanned structurally but not
individually classified. Both real regressions were found by execution, not by
reading, so the suite is the detector that matters here.

`gsd-tools.cjs:253` stays a raw exit deliberately: it is the ensureRuntimeBuild
bootstrap, which runs before cli-exit is required, so the seam does not yet
exist. It needs a second allowlist entry, which means #3910's "single allowlist
entry" criterion is unachievable as written.

Verification runs on the remote runner.

Refs #3910

* enhance(#3910): ban the raw terminator by construction

Adds local/require-registered-exit and registers it on all four globs:
src/**/*.cts, scripts/**/*.cjs, hooks/**/*.js, gsd-core/bin/**/*.cjs.

Registering on the .cts glob is load-bearing, not redundant — the emitted .cjs
mirrors are globally eslint-ignored, so a rule registered only on the emitted
globs is blind to the sources. That is the #3496 lesson, and it is how the
previous guard became invisible: n/no-process-exit was 'error' in one block yet
fired zero times on all three surfaces that mattered.

The dead n/no-process-exit: 'off' block for hooks is deleted in the same PR.
Phase 7 migrated every hook, so the exemption now protects nothing.

Two allowlist entries, not the one #3910 anticipated. terminateNow's body is
detected STRUCTURALLY — a process.exit lexically inside a function of that name
— rather than by a path and line number that rots. The second is
gsd-tools.cjs's ensureRuntimeBuild bootstrap, an inline disable with its reason
at the call site: it runs before ./lib/cli-exit.cjs is required, so the seam
does not exist yet and no migration is possible. #3910's 'single allowlist
entry' criterion is therefore unachievable as written, and is amended with the
measurement rather than quietly missed.

The rule is proven able to FAIL, per glob: four positive controls, one for each
registered glob. A guard that cannot be shown to fire is not a guard. Four
matching negative controls pin process.exitCode as never-flagged — conflating
it with process.exit is what inflated this epic's original census 2x. An
allowlist case and a near-miss (same shape, different function name) fix the
structural detection in place.

Verification runs on the remote runner.

Refs #3910

* fix(#3910): stop the detached catch from throwing, and scope the allowlist

Review findings, one of them a regression the previous fix introduced.

_handlePipelineRejection called error() from inside a DETACHED .catch().
error() now throws, so that throw became an unhandled promise rejection — and
on Node >=15 with --unhandled-rejections=throw, Node dumps a raw stack trace
with absolute paths on top of the clean Error: line. That was impossible before
this branch, because process.exit(1) terminated synchronously before any
rejection machinery could observe it. The handler now writes byte-identical
stderr itself, in both plain and --json-errors form, and sets exitCode in
place. This was the THIRD interceptor found, and like the first two it surfaced
by running the CLI rather than by reading code.

The rule's terminateNow allowlist had no path constraint, so any function
anywhere named terminateNow across all four globs inherited it. It now requires
the structural nesting check AND a cli-exit.cts basename — still no line
numbers to rot.

The four per-glob positive controls only varied a filename inside RuleTester,
which never resolves eslint.config.mjs. Since the rule is filename-agnostic,
all four exercised identical logic and none proved the rule was WIRED — this
epic's own failure mode. A registration test now asserts the rule resolves for
a real path in each glob, and it is proven able to fail: removing one glob's
registration flips the resolved value from [2] to undefined.

Three evasions the rule cannot catch (computed member, aliasing, .call/.apply)
are documented in its header and pinned by tests, labelled as known limits
rather than endorsed, so a future change that starts catching them is a
deliberate diff.

Refs #3910

* docs(#3910): document the raw-terminator ban

Reference and Explanation via a new docs/features fragment (FEATURES.md is
generated from it, not hand-edited). How-To:
docs/how-to/resolve-a-raw-terminator-finding.md, indexed from docs/README.md —
a contributor whose code trips the rule picks among three replacements by
surface (runMain/ExitError for a CLI path, terminateNow for a hook,
process.exitCode where the process should drain), and needs to know why
process.exitCode is correct and never flagged, since conflating the two is what
inflated this epic's original census 2x.

The page also names the three patterns the rule cannot catch and says plainly
that using one to dodge it is a review finding, not a fix — documenting them
without that sentence would read as a sanctioned workaround.

docs/INVENTORY.md deliberately untouched: eslint-rules/ is not a tracked family
in the manifest (verified — a regen produced a zero diff), so a hand-written row
would desync the table from the family it claims to belong to.

Refs #3910

* fix(#3910): a catch that sniffs the message swallows an ExitError

The remote run returned 41 failures, and one of them was a live production
regression rather than a test artifact.

`cmdMilestoneComplete`'s unstarted-phase guard re-threw only when
`e.message.startsWith('Cannot mark milestone complete:')`. `error()` used to
`process.exit(1)`, uncatchable, so the guard always fired. It now throws an
ExitError carrying no message, the string test fails, and the ExitError was
silently swallowed — the guard stopped blocking milestone completion entirely.
Proven against the real CLI: pre-fix, a milestone with an unstarted phase
archived at exit 0; post-fix it is blocked at exit 1 with the intended message.

That is a guard that silently stopped guarding, which is this epic's thesis
appearing inside the phase meant to enforce it. Worth stating plainly: an
earlier census DID examine this site, saw a `throw e`, and classified it as
rethrowing. It was wrong — the rethrow is conditional, and a conditional
rethrow on an inspected message is indistinguishable from an unconditional one
unless you read the predicate.

So the class was swept rather than patched where it was tripped over. An AST
census of every CatchClause across src/, gsd-core/bin/ and scripts/ found 38
conditional rethrows. Two more had the same defect and are fixed the same way:
`config.cts`'s `'No config.json'` sniff and `gsd-tools.cjs`'s
`e.name === 'WindowsError'`. The remaining 25 are provably unreachable — every
one wraps a bare fs, YAML, manifest-require or git-exec primitive that cannot
throw ExitError — and two were scanner false positives, both explained. Each
fix is an unconditional `instanceof ExitError` rethrow placed BEFORE any
inspection, matching the idiom command-routing-hub and gsd-tools already used.

Residual bound, stated rather than implied: zero known-reachable unfixed sites,
contingent only on error() never later being called inside one of those 25
primitive try blocks.

The remaining failures were harness artifacts, and the harnesses were corrected
to the new contract rather than the assertions weakened. Tests that mocked
`process.exit` to observe termination now catch ExitError and assert its code;
tests parsing stderr as a single JSON object still assert exactly that, with
their ad-hoc `node -e` scripts wrapped in runMain so it is true. milestone and
phase-resolution-parity needed no test change — they were correctly written
against the real bug and are what caught it.

Verification runs on the remote runner.

Also reframes the fragment to lead with the user-visible change — the

15af0f5536 enhance(#3951): B6+B7 — widen two unreachable lint rules and make the guard ledger true (#3965)
* fix(#3951): two lint rules that could not reach the code they govern

B6 names two widenings. Measuring them first turned up a defect the criterion did
not know about, and refuted the reason it gave for one of them.

1. no-adhoc-markdown-parsing self-gates on its own filename.

   Lines 107-110 short-circuit create() to {} unless the path matches
   /(?:^|\/)src\/[^/]+\.cts$/. B6 says to widen the files: glob in
   eslint.config.mjs - but doing only that ships an INERT rule, because the gate
   still returns {} for every new path. Both halves have to change, and the gate
   is the load-bearing one.

   That same regex hides a live hole: [^/]+ is FLAT-ONLY, so it requires the file
   to sit directly in src/. The registered glob is src/**/*.cts, which includes
   subdirectories. 28 .cts files - health-diagnostic-rules/ (10),
   installer-migrations/ (11), observability/ (3), host-integration-adapters/ (2),
   vendor/ (2) - are inside the registered glob and silently skipped.

   Measured with the gate neutralized: 0 violations there today. The hole is
   hiding nothing right now, and is fixed anyway, because "no violations today" is
   not a property that keeps holding.

   The fix is not invented: require-subprocess-timeout.cjs:196 already carries the
   correct form of this guard, /(?:^|\/)src\/.*\.cts$/ with .*, one directory over.
   Checked the other 21 rules for the same bug - no-adhoc-regex-escape and
   no-private-binary-resolution short-circuit only to exempt their own seam file,
   which is the right shape, and no-crlf-fragile-split has no filename gate at
   all. This bug is unique to the one rule.

2. no-adhoc-regex-escape could not see the shape that actually occurs.

   Line 396 gated the whole UNSAFE-NEW-REGEXP arm on arg.type === 'Identifier'.
   Every check below it - the _SOURCE provenance check, the
   isSoleReturnOfOwnParameter shape - lives inside that branch, so
   new RegExp(obj['key']) and new RegExp(cfg.pattern) were never examined at all.
   Runtime data arrives as a property access far more often than as a bare
   identifier, which is exactly why this rule never fired on the #3477 ReDoS.

   Widened to MemberExpression, measured by AST walk across all five registered
   blocks rather than by grep. 27 sites, zero TSAsExpression:

     18  safe new RegExp(X.source, flags)  -> exempted, keyed strictly on the
         PROPERTY being `source`, never on the object. Keying on the object would
         wave through X.anything and buy nothing. B6 estimated ~10; that was an
         undercount.
      3  _SOURCE-suffixed constants reached through a required module namespace
         (phaseId.BRACKET_PHASE_TOKEN_SOURCE) -> the same provenance-exempt class
         the rule already recognizes for bare identifiers, extended to reach them.
         Without this the widening produces 3 false flags.
      6  real findings -> marked, each a test extracting a pattern from a shipped
         file at test time, where the runtime contract IS the product.

   Deliberately the NARROW MemberExpression form. The rule's own
   isSoleReturnOfOwnParameter doc comment records that an earlier broad
   "any non-literal identifier" heuristic produced ~25 false positives and was
   rejected; a re-run of the census after this change flags exactly the 6 above
   and nothing else.

Verified by execution, not by reading: the gate now accepts src/<subdir>/x.cts,
still accepts flat src/x.cts, and still exempts paths outside src/ - each pinned
by a test proven to fail against the old regex. build:lib, lint and lint:ci all
exit 0.

* fix(#3951): give no-adhoc-markdown-parsing its reach, and fix the 80 parses it finds

The rule self-gates on filename AND is registered on one glob, so widening either
half alone is inert. Both move here: the gate now accepts tests/**/*.cjs and
scripts/**/*.cjs alongside src/**/*.cts, and eslint.config.mjs registers it on the
same two.

A test pins that the gate and the registration AGREE, in both directions. The
original defect was a gate narrower than its registration; the failure mode of
this fix is a gate wider than its registration. Both are silent, so the test
asserts the pair rather than either half.

80 violations across 43 files, all in tests/, zero in scripts/. 70 are routed
through the existing seams - scanFencedBlocks, collectSection, stripFencedCode,
tokenizeHeadings from markdown-sectionizer; splitTableRow, parseMarkdownTable,
findTableWithColumns from markdown-table. Headerless STATE.md tables use
splitTableRow per line, because parseMarkdownTable needs a real delimiter row.

10 are suppressed, 12.5%, well under the third that would have meant the rule is
mis-scoped for tests/ rather than the tests carrying debt. Each names its reason:
three regression guards (#3873 / bug-#21) are deliberately independent of the
generator's own fence handling, and routing them through the seam would have them
test the generator against itself; one is a negative-text probe that extracts
nothing; six are a shell-pipe-to-jq detector whose regex coincidentally matches the
table fingerprint and is not markdown parsing at all.

All ten sit in tests whose subject is .md content, which is normally a reason to
prefer the seam. The marker used is allow-adhoc-markdown, distinct from
no-source-grep's allow-test-rule, and lint:ci's lint-allow-test-rule-refs reports
the same 280/280 unverified count as before - checked rather than assumed, because
those two markers are easy to conflate.

The widening earned its keep immediately: it found a test that passed for the
wrong reason.

  tests/config-field-docs.test.cjs asserted notEqual(<cell>, '600') against the
  TYPE column instead of the DEFAULT column. notEqual('number', '600') is true
  forever, so the guard against workflow.subagent_timeout regressing to the old
  seconds default could never fire. docs/CONFIGURATION.md:434 is
  `| workflow.subagent_timeout | number | 300000 | ... |`, so the default is cell
  index 2; the assertion is now row-scoped through splitTableRow and reads 300000.

That is the argument for the widening in one case: the violation was invisible to
lint, the suite was green, and the assertion was vacuous. A rule that cannot reach
a file cannot tell you the file is lying.

Not fixed here, and recorded rather than assumed: #3426/#3239 are NOT reachable by
this widening. tests/package-legitimacy-gate.test.cjs yields zero violations even
with the gate bypassed - its hand-rolled scans are real, but built from line
filters and split('|') rather than the regex-literal fingerprints this rule
detects. They need new detectors. The epic assumed a wider glob would catch them.

build:lib, lint and lint:ci all exit 0; the post-fix census across tests/** and
scripts/** is 0 violations.

* fix(#3951): B7 — and #3356's defects were still live in the code

B7 asks that each closed child be driven fail-first with a behavioral identity
test at the CONSUMER's output. Four of eleven children had no test citing their
issue number. Auditing them by BEHAVIOR rather than by number-grep changed the
answer for three of the four.

#3364 and #2540 — traceability only. Both were implemented by #3941 and their
consumer-output tests exist and were shown failing-first; neither cited its
originating issue, so an audit that greps for the number reports them uncovered.
Tagged the specific asserting test in each file, following the citation form those
files already use.

#3372 — covered, but only at helper level, and the triage narrowed it. Of the four
commands the issue names, only estimate-cli's collectCalibrationSamples actually
enumerates phase dirs from disk; smart-entry, audit and roadmap-upgrade derive from
ROADMAP/body text and never reach the sentinel path, so they are benign by
construction and were left alone rather than "fixed" into churn. The existing #3882
rows asserted the helper's return value. Added a consumer-output test driving
`query estimate-calibrate` and asserting sample_count and the persisted document.
RED proof: reverted collectCalibrationSamples to a raw readdirSync and ran the real
CLI - sample_count 3, sentinel leaked; restored - sample_count 2.

#3356 — NOT covered, and BOTH halves of the defect were still live in source. The
issue is closed; the bug was not fixed. Fixed here rather than writing tests that
document a bug as correct.

  Defect 1, the contradicted row. quick.md:627 claimed
  `quick-tasks-append` performs "the equivalent write" to the Step 7c row. It did
  not: the `#` cell was a positional ordinal and `Directory` read `—`, because the
  route had no way to receive a quick id or task directory. Added OPTIONAL
  `--quick-id` / `--slug` / `--directory`. A caller with neither - fast.md, the
  original #2133 caller - omits them and gets the byte-identical prior row, so
  nothing existing changes. A caller that HAS a real id and directory now gets the
  canonical row quick.md:632 renders. The false-equivalence sentence itself is
  corrected rather than left to mislead the next reader.

  Defect 2, the forced re-derive. The route called readModifyWriteStateMd with no
  options, so a body-only append to the Quick Tasks table triggered a full
  re-derive of the disk-derived progress.* frontmatter. Every other body-only
  writer passes { resync: false } - src/state.cts's own docstring prescribes it -
  and this route was the lone outlier. RED proof: reverted the option, seeded a
  project with 2 real phase dirs and a curated total_phases of 25, ran
  quick-tasks-append; total_phases collapsed to 2. Restored; it stayed 25.

That second one is the shape this epic exists to close: a silent write that
replaces curated state with a re-derivation nobody asked for, exit 0 throughout.

build:lib, lint and lint:ci all exit 0.

* docs(#3951): amend B6's ledger to what was measured, and document the new flags

The ADR gains a ledger amendment in its own correction style - the sixth wrong
premise it records, found the same way as the other five, by measuring before
building.

B6 says the net guard count must fall. It rose: 62 -> 69, +7, measured from the
epic's filing commit to origin/next. The attribution is the point, though. Five of
the seven came from PRs unrelated to this epic, one was added by a phase of it, and
the epic did retire something sub-file - #3884 removed a detector with an explicit
"net: -1 detector, 0 added" ledger. Every named casualty is load-bearing, two
already carry retractions in this same document, and a sweep of all 22 rules plus
every scripts/lint-* found no provably dead guard. There is no honest way to make
the count fall; forcing it would trade coverage for a number, which is the Goodhart
outcome Decision 6 exists to prevent.

The amendment also records that B6's own prescribed fix for one widening was inert.
no-adhoc-markdown-parsing self-gates on its filename, so widening only the files:
glob - which is what the criterion says to do - ships a rule that still returns {}
for every new path. And #3426/#3239 are not reachable by that widening at all;
their scans use line filters and split('|'), not the regex fingerprints the rule
detects. The roster row tracked them against the wrong mechanism.

Three roster rows updated from aspiration to fact: the two widenings are DONE with
their measured counts, and lint-phase-enumeration-drift is marked RETAINED rather
than "expected casualty - verify before retiring", because Phase 5 verified it and
kept it.

The rule Decision 6 should carry forward is stated plainly: a guard ledger is a
claim about COVERAGE, not about COUNT. "Net count must fall" is measurable and
wrong. "Every guard is reachable, and each retirement names what makes its defect
unrepresentable" is the property that was actually wanted.

CLI-TOOLS.md documents the optional --quick-id/--slug/--directory flags and says
plainly that omitting them keeps the pre-#3356 row byte-identical, plus that the
append no longer re-derives progress frontmatter.

New features fragment (id 3951); FEATURES.md regenerated rather than hand-edited.

* test(#3951): correct four rows that pinned the lint rule's old narrow reach

The remote suite came back RED with 5 failures, all in tests/eslint-rules.test.cjs.
They are stale tests, not a regression: four rows assert that
no-adhoc-markdown-parsing is inert outside src/*.cts, which is exactly the
contract this deliverable changes.

Confirmed by reading rather than inferred from the names - the row at :1981 used
filename: 'tests/some.test.cjs' and filename: 'scripts/helper.cjs', the two roots
the rule now covers on purpose.

Worth recording WHY local gates missed this. npm run lint and lint:ci were green,
and the touched test files passed standalone. Lint only reports violations in real
files; these rows assert the rule's REACH using synthetic RuleTester filenames, so
nothing but the full suite could see them. Local green on a rule change says
nothing about the rule's own tests.

Each row is rewritten with BOTH halves rather than flipped from valid to invalid:

  - the same fingerprint under tests/ or scripts/ is now flagged, with the right
    messageId
  - the negative space is preserved - the same fingerprint under a path outside
    all three roots (gsd-core/bin/lib/foo.cjs) is still NOT flagged

The second half is the one that matters. Without it the rule has no boundary and
nothing would catch an over-wide gate later, which is the mirror image of the bug
this deliverable just fixed.

Each row is renamed to state the current contract; the old names said
"non-src/*.cts ... is not flagged" and would have been actively misleading once
the bodies changed.

Proven to test the widening rather than restate it: every flagged half was run
against HEAD~2's pre-widening rule and does NOT fire there, then against the
current rule and does. 12/12 on that probe; the full file is 178/178.

Swept for the same staleness elsewhere and found none.
require-subprocess-timeout's own "inert outside src/*.cts" row is untouched -
that rule's gate was not widened here - and no-adhoc-regex-escape's test file
already carries correctly-targeted rows.

* test(#3951): acknowledge the quick.md growth the attribution guard reported

The full suite came back RED with one failure, and it is mine:

  1 file(s) grew without an acknowledgment:
    quick.md grew 364 bytes

gsd-core/workflows/quick.md is runtime-loaded emitted content, so correcting
its false 'performs the equivalent write' claim trips emitted-attribution by
construction. This is the acknowledgment, not a workaround - there is nothing
to regenerate.

The fragment names ONE path, which is the only one the guard reported. The four
spent acknowledgments it also listed (audit-uat, plan-phase, progress, review)
belong to other fragments whose ripple the base already absorbs; they are inert,
not failures, and are deliberately NOT copied here - naming paths I did not
change would make this record false in the other direction.

Byte figure corrected before committing: the guard reported 37220 -> 37584
(+364), but origin/next has since moved and quick.md is 37232 there now, so the
measured delta is +352. The reason text says so and names the base as a moving
figure rather than pinning a number that is already stale.

Refs #3951

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

* test(#3951): move the quick.md growth ack to a trailer, delete the obsolete fragment

The acknowledgment mechanism changed under this branch. Merging next brought in
the redesign - it also deleted .github/workflows/ack-fragment-sweep.yml, which
was in the merge status and which I did not register at the time - and the guard
now says so directly:

  Add a trailer to a commit in this PR (never a new file).
    Emitted-Drift-Ack-Growth: quick.md - <why this growth is deliberate>

So tests/emitted-drift-acks/3951-quick-append-equivalence.json is obsolete on
arrival. A fragment file is no longer read by anything, and leaving it would be a
dead record that looks like an active one. It is deleted here rather than kept
"just in case".

The byte figure moved again with the merge: 37232 -> 37596, +364. The earlier
fragment said +352, measured before the merge auto-merged quick.md itself. The
trailer carries no number, which is the better design - the figure was stale
twice in two attempts.

Refs #3951

Emitted-Drift-Ack-Growth: quick.md — #3356/#3951 replaces a false claim with an accurate one. Line 627 said the `quick-tasks-append` shortcut "performs the equivalent write" to the Step 7c row rendered above it; it did not, and that was the documented half of #3356 — with no quick id or task directory the route emitted a positional ordinal in `#` and an em-dash in `Directory`, a visibly different row. The corrected sentence has to carry three facts the original elided: what the shortcut actually writes when it has neither input, that this is honest behavior for its real caller (`fast.md`, which has neither), and how a caller with both now gets the byte-identical canonical row via the new optional `--quick-id`/`--slug`/`--directory` flags. Prose is the product here — an executing agent reads this line to decide whether the shortcut is safe for its case, and a shorter correction would either drop the flags (leaving the reader unable to act on the fix) or drop the limitation (recreating the false claim in gentler words).

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3911

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3911

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3911

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3911

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

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

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

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

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

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

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

Verification runs on the remote runner.

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

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

ARCHITECTURE note on the hooks section.

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

Refs #3911

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

Two review findings.

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

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

Refs #3911

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

The remote run returned 7 failures across 3 real causes.

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

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

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

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

Verification runs on the remote runner.

Refs #3911

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

The staging fix means a Cursor install now correctly carries the two

removed. The golden diff is the evidence the packaging defect was real.

Refs #3911

* 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.

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.

8edace40d5 enhance(#3904): one exit module — generate the scripts-side copy from a single source (#3917)
* test(#3904): failing-first coverage for the drifted scripts-side exit module

The scripts/ copy of the CLI exit seam has no json-error arm, so an unexpected throw prints a raw stack where the documented contract promises {ok:false,reason,message}. Adds the consumer-altitude reproduction plus the negative space it must not swallow, the one-cell assertions for json-error mode, and the standalone-load constraint. RED until the generator lands.

* enhance(#3904): generate the scripts-side exit module from one source

src/cli-exit.cts becomes the single source of truth and scripts/lib/cli-exit.cjs a generated artifact of its compiled output, byte-compared by a --check entry in lint:generated-sync. The two had drifted: only the .cts copy emitted the documented {ok:false,reason,message} envelope on an unexpected throw, so a scripts-side tool printed a raw stack where docs/json-errors.md promises structured output.

The generated file is committed and must load on an unbuilt clone (64+ consumers, incl. check-env.cjs), and gsd-core/bin/lib/cli-exit.cjs is gitignored tsc output that doubles as the build sentinel, so it cannot be required from there. The exit module therefore drops its io.cjs import: the json-error-mode accessors move into it and io.cts re-exports them, leaving its export surface unchanged. The flag lives in a Symbol-keyed cell on globalThis because one source emitted to two locations means two module instances, and a module-level flag would give them two independent values.

* chore(#3904): changeset for the generated scripts-side exit module

* docs(#3904): name which surfaces honor the json-error envelope contract

docs/json-errors.md described the structured envelope as what runMain does without saying which copies of runMain actually had the branch — a claim that was silently false for every scripts/-side tool. Also drops a redundant source-grep test whose marker grew the unverified allow-test-rule pool past its ceiling; the behavioral test beside it proves the same property through real module resolution.

* test(#3904): compare exit verdicts, not stderr bytes, across the two copies

The parity test asserted byte-identical stderr, which the plain-text path cannot satisfy: the generated copy carries an 11-line banner, so its stack frames report line numbers offset by exactly that much, and the path normalizer stopped at the colon. Byte-identical stack traces were never the contract - two files at two paths necessarily differ there. Now compares the parsed envelope under json mode, the first line and exit code on the stack path, and exact output for ExitError.

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
from state-transition so existing importers are untouched — the same split
health-diagnostic-types made to break a CJS require cycle.

Refs #3873

* 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.

Refs #3873

* 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.

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

* 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.

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.

The two hostile-input fixtures used a literal phrase from

this file. These tests assert that an arbitrary phase name round-trips into
state.json as inert data -- the property holds for any string, so the
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.

* chore(#3227): ratchet the state-contract mutation floor to its measured score

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.

* 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.

* 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.

* 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.

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.

* 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
emits into every runtime's tree, so all 19 golden install-parity
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.

2972da4c9d enhance(#3619): ratchet the platform seam with local/no-private-binary-resolution (epic #3411 Phase 3) (#3636)
* chore(#3619): ratchet the platform seam with local/no-private-binary-resolution

Epic #3411 Phase 3, the ratchet. Scope revised with maintainer approval and
recorded on the issue: the epic's literal ask was a rule rejecting a bare-name
spawn outside the seam. Surveyed at ac1b6d679, ~30 such sites exist and none is
a defect — git, gh and npm ship native .exe that CreateProcess resolves unaided,
and the rest are POSIX-only tools. ADR-1703 rules 2 and 3 forbid grandfathering
and escape hatches, so a literal rule would be unsuppressable and would force
rewriting 30 correct calls.

The epic's actual thesis was four private RESOLVERS, not four bare spawns. So
the rule flags re-implementing resolution: reading PATHEXT in any casing from
any object, and a hardcoded list carrying two or more of .exe/.cmd/.bat/.com —
precisely the shapes fallow-runner's candidateNames and gsd-tools' PATHEXT
string had before Phases 1 and 2 deleted them.

Three boundaries were arrived at rather than assumed:

  two-or-more   a single .endsWith('.cmd') is a classification, not a candidate
                set; runtime-hooks-surface derives .cmd shim paths that way
  boundary-aware  a naive substring test flags .execute and .compacting, caught
                on src/host-integration.cts before it could become a false
                positive nobody could suppress
  suffix-anchored  the seam exemption matches src/shell-command-projection.cts
                exactly; a substring match would also exempt the dispatch test
                file. Case I9 pins it.

PATH scans are deliberately NOT flagged — membership checks (bin/install.js)
are indistinguishable from resolution scans, and an unsound rule in a
zero-escape-hatch architecture is worse than no rule.

To make the ratchet strict with no carve-out, resolveExecutableBinary gained
pathOverride: search THIS PATH, read everything else including PATHEXT from the
ambient environment. resolveFallowBinary now supplies its own search path
without hand-threading PATHEXT, which would itself have been a private read.
The three alternatives were all worse: exempting the file is grandfathering,
exempting the AST shape is a carve-out every future caller must replicate, and
dropping the pass-through would silently ignore a user's real PATHEXT — buying
a lint rule with a correctness regression.

eslint-rules/** is outside the rule's globs rather than exempted, because
portability-vocab.cjs owns the extension set. scripts/**/*.cjs got its own block
so that exclusion does not leave a hole in the ratchet.

Started green with nothing suppressed. Proven able to fail: a fixture with both
signals reports two errors.

Refs #3411

* fix(#3619): close the PATHEXT destructuring evasion and correct two overclaims

Adversarial review found a trivial evasion of the rule's primary signal: the
visitor only handled MemberExpression, so

  const { PATHEXT } = process.env
  const { PATHEXT: exts } = process.env
  const { Pathext } = opts.env

were all unflagged. That is a common idiom, not an exotic bypass. An ObjectPattern
visitor now catches it in every form — renamed, any casing, any receiver, string
keys — while leaving a computed key alone, since it is not statically decidable.
I10-I13 pin the invalid forms and V9/V10 pin PATH and the computed key.

Two overclaims corrected, both mine:

Standards review proved the docs were factually wrong. Both the ADR amendment and
the CONTEXT.md entry asserted that tests/shell-command-projection-dispatch.test.cjs
is still linted by this rule. It is not — the rule's surface is src, gsd-core/bin,
scripts and hooks, and tests/** is deliberately outside it because test setup
legitimately assigns process.env.PATHEXT (fallow-runner's P3 does exactly that).
The suffix-vs-substring distinction is therefore proven by RuleTester case I9
feeding a synthetic filename, NOT by real coverage of that file. Both documents now
say so.

The rule's own docstring claimed the seam exemption matches the seam path
'exactly'. It is a suffix match, so a nested foo/src/shell-command-projection.cts
would also be exempt. Suffix matching is kept — it is how sibling rules resolve
paths and the nested case does not exist — but the docstring now states the
boundary rather than overstating the precision.

The evasion fix was verified by executing eslint against both destructuring forms
in scripts/, not by inspection. Probe: 31/31.

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.

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

* 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.

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

* 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.

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

* 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

.gitignore, so it landed as a tracked file - the third time this step of
the new-.cts ripple has been missed on this epic.

* 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.

* 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.

* 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.

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.

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

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

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

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

tests/no-pending-3212-markers.test.cjs locks the epic's own closing
invariant (ADR §7: "assert zero pending #3212 markers remain") — ground
truth confirmed trivially true today (no phase left any such marker
behind), now regression-locked going forward.

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

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

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

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

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

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

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

  workflow .md content — the same Class A pattern as the ~159 sites
  already triaged elsewhere in this PR. Suppressed with the same
  established reason.
- lint-allow-test-rule-refs' ratchet ceiling needed re-raising again
  (301 -> 303) for the same reason as the two prior bumps: organic
  growth from unrelated, already-reviewed PRs landing concurrently,
  not a defect in this branch's own diff.

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.

* 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).

* 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.

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).

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

* 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
(eslint-rules/require-subprocess-timeout.cjs), DEFECT.CANARY-VERSION-LEAK
(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
is the record.

* 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.

Windows CI caught it: path.relative(root, abs) returns backslash-

5339dd60e5 feat(#3313): allow-test-rule total-file-count ratchet, F17 promotions (#3326)
Extends lint-allow-test-rule-refs.cjs with a second, independent check
alongside the existing uncited-citation identity ratchet: the total
number of distinct test files carrying any allow-test-rule marker
(cited or not) is now checked against a tight ceiling via the
previously-unwired assertTightCeiling primitive (allowlist-ratchet.cjs,
0 prior callers). A cited exemption is legitimate under ADR-456 but
nothing stopped the raw total from growing forever - this closes that
gap without duplicating the file walk (both checks consume one shared
walkTestFiles pass).

Ceiling introduced at the exact measured high-water mark (314 files,
grace 3) rather than a padded estimate, per "budgets may only
decrease."

Also lands the two F17 pieces (absorbed from the now-closed #1885)
that had no precondition:
- --max-warnings 0 added to lint/lint:ci
- local/no-source-grep promoted warn->error in the scripts/bin/
  eslint-rules glob block (already error in the tests/ glob)

Both promotions were pre-verified against a zero-warning tree (fresh
non-cached eslint run) before flipping, per the maintainer's clean-
tree-first decision.

Not included: local/no-elapsed-assertion promotion, which stays warn
pending #3314 (H2) - 10 of 19 clock-touching src modules have no
sanctioned time-control mechanism until ADR-456 is amended there.

H1 of epic #3053, absorbing #1885 F17.

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.

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

* 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.

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

* 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.

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

* 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.

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

* 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.

c28134ab39 fix(#3271): delete 25 duplicated folded test suites and fix three runner defects found doing it (#3285)
* test(#3271): guard against a folded suite appearing twice in one host

Adds local/no-duplicate-fold-marker, an AST rule that reports the second and
every subsequent `folded:<name>` marker in a host file, plus RuleTester cases
and a tree-wide regression assertion.

Failing-first on purpose: the rule is registered at error and the 25 duplicated
regions are still present, so eslint and the new tree-wide test are RED. The
deletions land in the next commit.

The marker key is the whitespace-delimited token after `folded:` — not the
issue's `[a-z0-9-]*` slice, which truncates at `.` and false-positives on
tests/model-resolver.test.cjs where feat-443-effort-fast-mode.integration and
feat-443-effort-fast-mode are two distinct folded suites.

Refs #3271

* fix(#3271): delete 25 duplicated folded suites from three install hosts

Three consolidated install suites each carried a verbatim second copy of a
contiguous run of #1969 B1 folded blocks. Byte-identical, constant offset, and
green — each duplicated block registered and ran twice on every lane.

  tests/install.test.cjs                   5981-9937  (3957 lines, 18 blocks)
  tests/install-minimal-hooks.test.cjs     2734-4015  (1282 lines,  5 blocks)
  tests/install-write-confinement.test.cjs 1754-2321  ( 568 lines,  2 blocks)

Introduced by 6d072435d (#1975 re-applying #1970's hunks on a tree that already
had them, 2026-07-03) — one stale-base re-application, three files, one commit.
Verified by marker-count bisect: 1 at 4f779eda4 and 0cc7a1a42, 2 from 6d072435d
onward.

The later copy is deleted in each case, so every file returns to what its
authoring batch produced and blame on the surviving lines stays accurate.
local/no-duplicate-fold-marker, red on the previous commit, is now green.

tests/model-resolver.test.cjs is untouched: the issue lists it, but its two
blocks are folded from two different files and are not identical. It is a false
positive of the issue's own grep, whose `[a-z0-9-]*` key truncates at `.`.

Fixes #3271

* test(#3271): property-test marker identity and pin the alias non-goal

Three review findings, all fixed inline:

1. foldMarkerOf is a parser and carried no fast-check property test. Raised
   independently by the /code-review standards axis and the isolated adversarial
   pass; the file already establishes the fc.property-driving-ruleTester idiom
   for a sibling rule. Added, two arms over markers generated from [a-z0-9-._]:
   the same marker twice always reports exactly once against firstLine 1, and
   two distinct markers never collide. The alphabet includes `.` on purpose —
   an implementation keyed on the issue's [a-z0-9-]* slice passes arm 1 and
   fails arm 2, which is exactly the model-resolver false positive.

2. meta.docs.category was the novel value 'Test hygiene'; all 16 sibling local
   rules use 'Best Practices', 'Portability' or 'Reliability'. Now
   'Best Practices'.

3. A call through a further alias (const d = __foldDescribe) was unreported and
   undocumented — accidental rather than deliberate. It is now the fourth entry
   in the rule's documented non-goals, with the reason, and pinned by a valid
   RuleTester case so it cannot drift silently.

Refs #3271

* test(#3271): name the step and elapsed time when a baseline build fails

buildBaselineAtRef runs four bounded steps and, when one exceeded its bound,
threw a bare "spawnSync ETIMEDOUT" naming neither the step nor how long
anything took. Diagnosing one real failure took four separate experiments to
recover information the throw already had.

Each step is now timed, and any throw carries the breakdown: which step failed,
its elapsed time, the timings of every step that completed before it, all three
bounds, and the tail of the child's captured stdout/stderr.

The failure message is deliberately the carrier. On the remote runner the
captured output field comes back empty in failures.json while error and stack
survive verbatim, so the message is the only channel that reaches a reader of a
remote verdict.

Refs #3271

* fix(#3271): size the baseline generator bound for the machine it runs on

Instrumentation from a real remote-runner failure gave the breakdown:

  git-worktree-add=15.1s  npm-run-build-lib=19.8s  gen-emitted-baseline=FAILED@300.1s

Steps 1 and 2 are comfortable. Only the generator exceeds its bound, and it is
not hung — it needs more than 300s there.

Measured ladder for that step: ~22s idle in a container, ~39s end-to-end in a
clean container, ~142s with 8 CPU burners on 8 cores, and >300s under the real
suite. Its cost is 19 sequential installer spawns, and spawn latency is exactly
where a container degrades worst (3.9x slower than host, against 1.1x for file
IO) — which is why a CPU-only load test did not reproduce it and why four
earlier hypotheses (container slowness, network, shallow clone, CPU contention)
all measured clean.

The 300s bound was sized on an idle machine for a step that never runs on one.
Under the remote runner the on-disk baseline cache is structurally absent — CI
restores it via actions/cache keyed on github.event.pull_request.base.sha, a key
that exists only inside GitHub Actions — so this slow path runs on every remote
verification. The result: this gate has passed 0 times in 754 runs, failing 80
times and never once executing successfully.

Raised to the 600000ms ceiling that local/no-unbounded-spawn treats as the
largest meaningful bound; the other two bounds are untouched. This makes the
gate RUN, which is the point: the alternative considered and rejected was
degrading the timeout to a skip, and that was measured to turn the suite green
with the gate silently not running at all.

The real remedy is making the cache reachable from the remote runner so the
in-job build returns to being the rare fallback ADR-2719 §5 describes. That is a
gsd-test-runner change, not one this repo can make.

  ENOENT: no such file or directory, link '/work/hooks/dist/gsd-config-reload.js'
    -> '/tmp/gsd-2930-overlay-6nOZay/hooks/dist/gsd-config-reload.js'

buildOverlayRepo enumerates names with readdirSync and then acts on each one, so
statSync, copyFileSync and linkSync all sit in a TOCTOU window. hooks/dist is
regenerated by an ATOMIC REPLACE (scripts/build-hooks.js unlinks and renames), so
any concurrently running test that rebuilds hooks retires a just-listed name
mid-walk and the overlay dies on it. linkOrCopyFile already tolerated EXDEV and
EPERM; ENOENT went straight through.

On ENOENT the source is now re-examined ONCE rather than slept on. An atomic
rename is a single syscall, so by the time the failure surfaces the successor is
either already in place (the retry succeeds) or the path has genuinely left the
tree, in which case there is nothing to mirror and the leaf is skipped. No sleep
and no spin: a timing-based wait here would be the very flake being fixed. Every
other errno still propagates untouched, so a real permission or IO fault stays a
hard failure.

Five tests hold the boundary: gone-for-good skips without retrying, mid-replace
retries exactly once and places the file, EACCES still throws, a real linkSync
ENOENT is injected by monkeypatching fs and restoring it in a finally (never a
mode-bit trick, which root bypasses), and isMissingPath accepts only ENOENT.

* fix(#3271): order the timeout ladder inward-out and lock it

Two review blockers, both real.

The generator bound had been raised to 600000ms — exactly the whole-chunk timeout
in scripts/run-tests.cjs:973. A step bound equal to the chunk ceiling loses the
race: the chunk is killed first and the failure arrives as an opaque "no failed
step" kill, so the per-step diagnostic added a commit earlier was built and then
made unreachable in the same change.

Separately the #2767 test declared a per-test timeout of 300000ms, BELOW the
inner bound it was meant to permit, so it could still die at the exact 300s
ceiling this was supposed to lift — via node:test's timeout rather than
spawnSync's. Its sibling declared 900000ms, above the chunk ceiling, which is the
same opaque-kill hazard from the other direction.

The three bounds only produce a useful failure if they fire inward-out, so they
now do: step 360s, per-test 480s, chunk 600s. 360s is ~3x the passing observation
(91.6s / 115.8s) and 20% above the censored 300.1s timeout, while leaving 240s of
chunk headroom for every other file sharing it. Four tests lock the ordering,
including a drift guard on the exported values — without it, editing a call
site's literal timeout would leave the ordering assertions passing while the real
ladder inverted.

Also from review:

- err.gsdBaselineStep and err.gsdBaselineTimings were written and never read
  anywhere in the tree; only the rewritten message is consumed. Removed rather
  than kept as speculative surface.
- buildOverlayRepo discarded placeVanishableLeaf's boolean at both call sites, so
  a vanished leaf left the overlay with no accounting at all. It now collects the
  skipped paths and warns once. Not thrown: a source that left the tree really is
  not part of the snapshot, and throwing would reintroduce the crash the
  tolerance removes — but silence would let a dropped leaf resurface later as an
  unrelated missing-file assertion.
- The instrumentation commit shipped no test. One now drives a real failure and
  asserts the message names the step, its elapsed time, and the bounds.

* chore(#3271): backfill the changeset PR number

* fix(#3271): bound a hook fan-out as its own class, not as a bare probe

CI failure on PR #3285, job full test (windows-latest, 22, shard 2/3) — every
other lane green, including windows-latest node 24 across all three shards:

  not ok 1 - blocks push when any to-be-pushed commit matches local blocked regex
    error: bash .githooks\pre-push failed — outcome=timed_out exitCode=null stderr=
    duration_ms: 15040.2168

A bound, not a hang: the test supplies stdin via input:, so the hook is not
blocked reading its ref list, and the duration lands exactly on the 15000ms
bound.

The site used PROBE_TIMEOUT_MS, which tests/helpers/timeouts.cjs documents as "a
single short CLI query or node -e probe against a temp fixture". This is not
that. It spawns bash running .githooks/pre-push, and the hook then invokes a MOCK
git that is itself a bash script, so one runHook is roughly four Git Bash spawns.
On Windows each is Defender-scanned and the first hook test in a file pays cold
start on top. That module's own docstring warns against precisely this: a call
site that differs from its class must not be forced onto a shared value that does
not describe it.

HOOK_FANOUT_TIMEOUT_MS is that missing class — 60000ms, 4x the bound that failed
and half INSTALL_TIMEOUT_MS, which is the right order: a hook fan-out is much
lighter than a full installer run and far heavier than reading back a version
string. Two tests lock the ordering against both neighbours, including one
asserting real margin over the censored 15040ms observation, since a bound that
merely matched what was measured would be the same defect again.

Scoped deliberately: the other ~360 runHook sites keep their current bounds. This
adds the norm and applies it where a real failure demonstrated the need, rather
than sweeping a value across sites with no evidence for any of them.

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.

Refs #1953

* 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.

0c413bbc9c chore(#3059): close the ESLint glob-coverage escape and guard it (#3277)
* chore(#3059): close the ESLint glob-coverage escape and guard it

62 tracked source files matched no `files:` glob in eslint.config.mjs, so
ESLint skipped them entirely while `eslint .` still exited 0 — including all
26 files under hooks/, the enforcement machinery itself.

Covers 56 of them (eslint-rules/, hooks/, bin/lib/, pi/, examples/, vscode/,
the plugin shims, root *.mjs) and allowlists the 6 deliberate
must-not-compile brand-typing fixtures with a recorded reason each.

hooks/** is covered with n/no-process-exit deliberately off: a hook's whole
contract is its exit code, several exits are load-bearing stdin-timeout
guards where nothing else terminates the process, and ADR-0012/0174 scope the
no-process-exit convention to the Command Routing Hub. bin/lib/ui-safety-gate.cjs
is dual-mode, so it keeps the rule live and takes two targeted disables in its
require.main===module tail instead.

Adds scripts/lint-eslint-glob-coverage.cjs + a node:test drift guard so the
class cannot regrow: allowlist entries require a non-empty reason, the list
ratchets down only (a stale entry fails), and a tracked-count floor means a
broken `git ls-files` fails rather than reporting clean.

unlinted files. The real figure is 56 (56 covered + 6 allowlisted = 62).
That was user-facing CHANGELOG text and was wrong; corrected, along with three
consequential figures in the design record.

CLAUDE.md requires a fast-check property test for parsers and budget limits,
and listTrackedSourceFiles is a parser. The standards review called this
"satisfied in spirit"; it is not. Adds three properties driving the real
exported parser through an injected execFile: extension totality/soundness
including a trailing terminator, backslash-normalization totality, and
CRLF/LF equivalence — the invariant the repo's recurring CRLF defect class
breaks.

Also de-duplicates the anchor rows onto one shared resolver, kept deliberately
independent of the guard's own resolveFileCoverage so an anchor still fails if
that resolution regresses, and records in the guard's header why the
bin/install.js family is NOT allowlisted: it resolves to 2 rules under
ADR-1703, so an entry would trip the allowlist_stale ratchet.

* fix(#3059): make the coverage guard's git call container-safe

The remote runner reported the guard degrading to `git_failed` on both Node
lanes:

  fatal: detected dubious ownership in repository at '/work'

The runner executes in a container where the repo is owned by a different UID,
so git refuses to operate on it. The guard's degraded-verdict path worked
exactly as designed — it reported the failure instead of throwing or falsely
reporting clean — but a guard that cannot run in CI is not a gate.

`git ls-files` is now invoked as `git -c safe.directory=* ls-files`. `-c`
scopes the override to the single invocation and mutates no config file, and
the wildcard is appropriate because this command only enumerates tracked paths
in the repository it is already executing inside.

Adds a regression test that captures the argv through the injected execFile
seam and asserts `-c safe.directory=*` precedes `ls-files`, so the container
case is pinned behaviorally rather than by reading the script's source.

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.

* docs(#3183): amend ADR-3180 for the Phase 1/3 boundary re-slice

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.

* chore(#3183): register planning-scope.cjs in the eslint migration list

tests/repo-invariants.test.cjs asserts every bin/lib/*.cjs is linted xor
ignored per its ADR-457 migration state. The new planning-scope module closed
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
test rather than by lint:ci, so the local pipeline stayed green while it was
missing.

Generated from src/planning-scope.cts, so the .cjs is ignored and the .cts is
linted, matching every other migrated module.

* 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.

9faacc0c15 test(#3148): bound the long tail and delete the unbounded-spawn allowlist (#3192)
* test(#3148): bound the long tail and delete the allowlist

Migrates the final 170 unbounded sync spawn sites across 49 files, then
removes the allowlist entirely. local/no-unbounded-spawn now runs with no
exemption surface across tests/**: there is no file to add a name to.

drift-detection's throw-native git() helper routes to gitOrThrow -- bare
runGit would have taken 16 call sites quiet on failure. commands.test.cjs
has two independently-scoped runGsdTools/runCli helpers, one already bounded
and one not; they are kept distinct rather than unified, the same trap as the
two same-named git() helpers in Wave 1.

runNpm's bound was erasable. Its options spread callerOptions after the
defaults, so an explicit timeout:undefined silently dropped the 180000ms
bound -- the rule flagged it and was right; it was not a false positive. Fixed
by destructuring with a default, with a test that fails when the default is
removed.

Two sites stay on a raw spawn with an explicit timeout because the seam
cannot express them: one needs shell:true for npm.cmd on Windows, one
redirects stdout to a real fd. Both are the rule's own documented second
option, not an escape from it.

Closure verified rather than asserted: the derivation scan reports 0 unbounded
spawn helpers and 0 unbounded direct git call sites, and a temporary file
carrying an unbounded spawn still errors with the allowlist gone.

Closes #3064.

* test(#3148): close a hole in the guard's own eslint-disable ban

The ban listed only the top level of tests/, so it was blind to 37 .cjs
files under tests/helpers, qa, observability, fixtures and dispatch. With the
allowlist deleted this test is the sole remaining way to detect someone
silencing the rule inline, so the gap was load-bearing: a nested file could
carry an unbounded spawn plus an eslint-disable and pass everything.

Proven before and after. A probe planted under tests/helpers with both was
invisible to the guard and clean under eslint; after making the listing
recursive the guard fails on it. The scanned set goes from 771 files to 808.

Pre-existing since the guard shipped, but this wave is what promoted it to
sole defense, so it is fixed here rather than filed.

Also converts the last hand-rolled throw check to throwIfFailed and the last
re-derived legacy shape to compose toLegacyResult, which makes the epic's
none-remain claim true rather than nearly true. toLegacyResult itself is not
widened -- eight callers depend on its shape and one consumer does not
justify changing a shared contract.

* fix(#3148): correct seam incoherence at the bound and a slow review-lane error path

Two real failures from the remote runner, both fixed at the cause.

The seam could return outcome TIMED_OUT together with exitCode 0. At the
exact bound spawnSync reports ETIMEDOUT while the child has already exited
with a real status, and toSeamResult classified on the error code while
passing status straight through -- an incoherent pair its own boundary test
was written to catch, and did. A status that is not null is direct evidence
the child exited on its own, so it now decides the outcome before the
error-code branches run. process-seam.cjs was deliberately untouched by every
earlier wave; this is a defect in the module itself, kept surgical, with a
unit test that fails against the old logic.

review-lane with an unknown subcommand fell through to its usage error only
after loading the capability registry and building a per-lane plan, which
spawns one child process per lane -- up to twelve. The error path took
~1288ms instead of ~119ms, and under bench load it outran a caller's spawn
timeout and was killed before writing anything, which is the empty stdout and
stderr CI saw. It now fails fast before any of that work begins.

This is the epic's first production change. It is user-facing, so it carries
a changeset rather than a no-changelog label.

* test(#3148): replace a real-race timeout test with a deterministic one

E9 raced git rev-parse against a 1ms bound and assumed git always lost. On a
warm container git finishes first, spawnSync returns status 0 with no error
at all, the seam correctly classifies EXITED, and gitOrThrow correctly does
not throw -- so the test failed on both lanes. A probe confirms a genuine
timeout always carries status null, so this was never the seam misbehaving.

Raising the bound would only lengthen the odds, which is the same defect with
better luck. The test now drives gitOrThrow against a stubbed runGit that
returns a synthetic TIMED_OUT result, so it asserts exactly what it always
meant to -- that a timeout propagates as a throw -- with no timing
dependence. Five consecutive runs are identical where the old one varied.

I wrote this test in Wave 0; it is a real-race test by construction and
CLAUDE.md says to replace those rather than re-run them.

27aa40f65e fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ directory (#3175)
* test(#3023): failing-first guard — pi must not stage hooks in its reserved dir

pi reserves <configDir>/hooks as its deprecated extension location and warns
on every startup when it exists. Assert a pi install stages the shared hook
bundle under gsd-hooks/ instead, manifests it there, and never creates hooks/.

Also adds pi to the local-scope dir table in install-shared.cjs: pi was in
RUNTIME_META but not LOCAL_DIR_NAME, so scope:'local' resolved
path.join(root, undefined) and no local pi install could be exercised.

Fails before the fix. Verified via the remote runner.

* fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ dir

pi reserves <configDir>/hooks as its now-deprecated extension location and
warns on every startup when that directory merely exists — checkDeprecatedExtensionDirs()
guards the warning with a bare existsSync(), unlike its tools/ sibling. GSD staged
its shared hook bundle exactly there, and pi's advised remediation (move it to
extensions/) would break the adapter's paths and expose GSD's .js helpers to pi's
extension auto-discovery.

The bundle directory name is now runtime-descriptor-driven: hostBehaviors
.sharedHooksDirName, defaulting to 'hooks' so all 18 other runtimes are
byte-identical. pi sets 'gsd-hooks'. The name is validated as a single path
segment — separators, dot-only segments, trailing dots, absolute paths, NUL,
and Windows reserved device names all fall back to the default, because the
value is joined onto a user's config root and written to.

Renamed in place rather than relocated: hook scripts resolve siblings via
__dirname/.., so a depth change would silently break them.

- install / uninstall / manifest sites all read the resolved name
- pi/gsd.cjs probes gsd-hooks then hooks, so dev checkouts and half-upgraded
  trees still resolve; the never-throws contract is preserved
- new migration 009 retires the legacy pi hooks/ dir on upgrade, using a new
  non-recursive remove-empty-dir engine primitive (rmdirSync only,
  symlink-refusing, containment-guarded); ADR-0008 amended accordingly
- fixes two latent name-dependencies the rename exposed: the stale-hook scan
  and the injection scanner's self-exclusion both hardcoded 'hooks'

Verified on the remote runner.

Closes #3023

* fix(#3023): close review findings and align emitted provenance with the rename

Adversarial review found two defects, and the remote runner found four
failure clusters. All fixed here.

Review BLOCKER — detect-custom-files was blind to the renamed bundle.
GSD_PREFIX_MANAGED_DIRS in gsd-tools.cjs hardcoded 'hooks', so for pi the
whole gsd-hooks/ tree was invisible to the custom-file scan and user-added
files there were never backed up before the next update's clean-install wipe.
The dir set now resolves via the .gsd-runtime marker plus the shipped
capability registry (never bin/install.js, which is not shipped into installed
trees), and falls back to scanning every known candidate when the runtime
cannot be determined — over-scanning is safe, under-scanning is the data loss.

Review MAJOR — the pi adapter bound to an empty bundle. resolveSharedHooksDir
accepted any directory, so an interrupted install left gsd-hooks/ winning over
a fully-staged legacy hooks/ and every hook silently no-opped. A candidate now
qualifies only if it is non-empty.

Remote-runner clusters:
- emitted-provenance had no rule for the gsd-hooks/ family; added two pi-scoped
  rules pointing at the same sources the existing hooks/ rules use. The table is
  total, so an unattributed family is a hard failure by design.
- pi tests in install-minimal-hooks and the install integration suite asserted
  the old layout; updated to derive the dir name from the descriptor rather than
  hardcoding either name.
- 19 unrelated-looking failures on node22 only were a leaked fs mock: t.after()
  runs in registration order, cleanup was registered before mock.restoreAll(),
  and node22's JS rimraf calls the public fs.rmdirSync while node24's native
  path does not — so the EACCES stub leaked process-wide on one lane. Restore
  now runs first.

Verified on the remote runner.

* fix(#3023): honor PI_CODING_AGENT_DIR, ack the rename ripple, fix expandTilde

pi resolves its agent dir as PI_CODING_AGENT_DIR ?? ~/<CONFIG_DIR_NAME>/agent
(packages/coding-agent/src/config.ts). GSD's pi descriptor declared an empty
configHome.env, so a user with that variable set had GSD installed where pi
never looks. Added the env name; the dot-home-nested resolver already handled
the override, so no resolver logic changed.

Also fixes expandTilde in the shared runtime-homes resolver, found while adding
that: it hardcoded os.homedir() and ignored the opts.home every caller threads,
so EVERY runtime's tilde-valued env override (claude, antigravity, windsurf, pi)
silently resolved against the real home. That is a correctness bug and a
test-escape hazard — a sandboxed test asserting on a tilde override reached the
developer's actual home directory. Now threaded through every branch; behavior
with no injected home is unchanged.

Adds the emitted-drift ack fragment for the 58 pi paths whose emitted location
moved with the rename. The provenance rules satisfy the totality gate; the
differential gate needs the ack because the hook sources are byte-unchanged —
only the installer's target directory moved. The two hook files this branch
genuinely edits stay attributed and are not double-acked.

Note on piConfig.configDir: it is read from pi's OWN installed package.json
(getPackageDir walks up from pi's __dirname), alongside piConfig.name — a
white-label setting for a redistributed pi fork, not a per-project user setting.
Documented accordingly rather than treated as an unsupported override.

Verified on the remote runner.

* fix(#3023): reject blank env overrides, pin adapter/descriptor parity

Three review findings, all fixed.

A whitespace-only config-dir override was accepted verbatim: the guard was
`if (val)`, falsy only for the empty string, so PI_CODING_AGENT_DIR='   '
resolved to a literal three-space directory name instead of falling back to the
descriptor default. Fixed across every env-consuming branch — dot-home,
dot-home-nested, all three xdg steps, and generic-agents-root — not just pi's.
Non-blank values are still never trimmed, so '~/My Agent Dir' keeps working.

pi/gsd.cjs's probe list and the descriptor were two independent sources of truth
for the bundle directory name; a future rename would have desynced them silently
and left every pi hook quiet with no error. The probe list stays deliberate — it
must resolve in a dev checkout and a half-upgraded tree, where the registry's
answer would be wrong — so this adds the parity assertion the repo's
generative-fix-divergence rule calls for: the descriptor value must be the FIRST
candidate, and the default must remain present.

Changeset body rewritten to cover the two later user-facing fixes it had not
caught up with.

Verified on the remote runner.

* chore(#3023): backfill changeset PR number

* fix(#3023): anchor injection-scan patterns and fix a macOS detection hole

CI's security job flagged CONTEXT.md:124 — pre-existing prose reading 'not the
same fact as a genuinely empty or absent one'. The match was the 'act as a'
INSIDE 'f-act as a': the pattern had no left word boundary, so any word ending
in act tripped it (fact, impact, contract, artifact, interact, redact,
abstract). My four-line CONTEXT.md edit dragged the latent false positive into
this PR because the scan is diff-scoped by file but reads whole files. Anchored
with (^|[^[:alnum:]]) rather than rewording maintainer-owned prose, which would
have left the class alive for the next PR touching any file saying 'fact as a'.

Auditing the rest of the list for the same class surfaced a real detection hole:
the eval/exec/Function patterns matched a quote via \x27, a GNU-grep-only hex
escape. BSD/macOS grep reads it as four literal characters, so single-quoted
eval('...')/exec('...') payloads were NEVER detected there while passing on
GNU-grep CI. Replaced with a literal apostrophe class.

Boundaries were added only where a real word-suffix collision exists; exec,
jailbreak, developer mode and the role-manipulation family were audited and
deliberately left unanchored. 22 new cases cover both directions — the false
positives now scan clean, and every real payload still fires, including the
quote/punctuation/start-of-line boundary forms.

Also builds this branch's injection test fixture at runtime instead of carrying
the literal phrase, so the payload keeps its teeth without tripping the scan.

Verified on the remote runner.

2afe17bbdb test(#3143): add the no-unbounded-spawn guard and throw-preserving git fixture (#3150)
* test(#3143): add no-unbounded-spawn guard and throw-preserving git fixture

Adds the ESLint rule local/no-unbounded-spawn, wired into the tests/**/*.cjs
block, plus an allowlist that only ratchets down: a listed file with zero
violations reports its own entry as stale.

The rule resolves renamed destructures and chained requires rather than
matching literal callee names -- both forms exist in the suite today and a
name-only matcher leaves them permanently invisible. It resolves an options
object held in a single-write const, which is what keeps process-seam.cjs,
the bounded reference implementation, from flagging itself.

timeout: 0 and anything above the 600000ms ceiling are rejected as only
nominally bounded.

Adds tests/helpers/git-fixture.cjs so a migrated execSync call site keeps
its throw-on-non-zero contract; process-seam.cjs is unchanged.

* test(#3143): prove the allowlist guards can actually fail

Extracts the D4/D6/D7/D8 checks into pure helpers and drives each against a
synthetic fixture carrying an injected violation. Without this the suite only
proved that today's clean data passes, which a deleted check would also
satisfy.

* fix(#3143): close two ceiling and alias escapes found in review

Nested arithmetic bypassed the ceiling entirely: the numeric evaluator only
resolved a flat literal, so `timeout: 60 * 60 * 1000` (3600000ms, six times
the ceiling) fell through to trusted and reported nothing. The evaluator now
recurses through arithmetic and unary signs with a depth cap.

Alias resolution was traversal-order dependent, not scope dependent: a call
textually above its own require destructure saw an empty alias map and
reported clean. The map is now built in a Program pre-pass.

Also: an explicit timeoutMs:undefined no longer overwrites the git fixture
default via spread, adds the missing seam-routed rule test, and de-duplicates
the repeated try/catch in the fixture tests.

7203011400 feat(#3072): ship the deferred MCP served catalog (resources + prompts) (#3083)
* test(#3072): add failing-first coverage for the mcp served catalog

55 input-class rows from the phase test matrix, across four suites: the
catalog module over injected readFile/readDir seams, the protocol surface
through handleMessage, the install-vs-catalog parity gate, and fast-check
properties for uri round-trip, traversal refusal, and pagination partition.

src/mcp-catalog.cts lands as a skeleton whose functions throw, so the suites
fail on BEHAVIOR rather than on a missing module. The REASON enum is real so
tests assert typed codes instead of message prose.

Hostile coverage for the one client-controlled path surface (resources/read):
dot-dot and backslash traversal, percent- and double-encoded traversal,
absolute posix and windows paths, file:// scheme, null byte, symlink escape,
unindexed sibling, non-string and empty uri, wrong root segment.

IO faults are injected by monkeypatching the seam, never chmod 0o000 - root
bypasses mode bits, so a permission-based test silently passes with zero
coverage in root CI.

gsd-mcp-server now serves GSD's own content alongside its three tools: the
workflow, reference and command tree as MCP resources (resources/list, cursor
paginated, and resources/read over gsd://<segment>/<relpath> uris) and the 71
commands/gsd/*.md as MCP prompts keyed by bare command name. initialize
advertises resources and prompts, and deliberately does not advertise
subscribe or listChanged - the catalog is fixed for a server process lifetime,
so declaring a notification we never send would be a lie a host acts on.

Composition scope is SHARED, not re-declared. shouldCompose lives in
src/mcp-catalog.cts and bin/install.js now imports it instead of carrying its
own regex, so the served catalog and the installed file floor cannot drift on
what gets composed. Proven behavior-preserving across all 2871 tracked paths
plus windows-backslash, absolute and near-miss-prefix cases: zero mismatches.
tests/mcp-catalog-parity.test.cjs asserts served text equals the installer
composition-stage text over the real tree, with anti-vacuity guards requiring
both a marker-bearing workflow and a non-composed file in the comparison set.

Two measurements corrected the literal issue text. Composition is scoped to
gsd-core/workflows/ only, because a reference or command that documents marker
syntax with an unfenced example would otherwise be parsed as carrying a real
marker and have that line lossily dropped. And parity is asserted at the
composition stage rather than against an emitted runtime tree, since install
applies per-runtime path rewrites afterwards and the catalog is host-agnostic,
so byte equality with any one runtime would be false by construction.

resources/read is the one client-controlled path surface and is guarded in two
independent layers: the uri must be an exact key in the prebuilt index, which
defeats every traversal string by construction, and the mapped path is then
re-checked with validatePath so a symlink planted inside a root after indexing
is still refused.

Also fixes a real drift defect found while here: SERVER_VERSION was hardcoded
1.7.0 while the package is at 1.9.1. It now resolves lazily from VERSION or
package.json, reusing the precedent in runtime-artifact-conversion.

Closes #3072

* test(#3072): make the catalog parity gate drive the real installer

Review found the parity gate vacuous: it never imported or spawned
bin/install.js, and recomputed the installer side with the SAME shouldCompose
and composeWorkflow the catalog calls internally. It therefore proved only
that src/mcp-catalog.cts is self-consistent. The old row 52 compared
shouldCompose against a regex literal frozen in the test file rather than
against the installer at all. An inline divergent regex re-added to
bin/install.js - the exact regression ADR-1671 asks this gate to catch - would
have left the suite green.

The gate now spawns a real bin/install.js and compares the composition
DECISION, observed as gsd:section marker survival, against what the catalog
serves for the same files. Marker presence is the right observable because the
installer applies per-runtime path rewrites after composing while the catalog
applies none, so raw byte equality between the two surfaces is false by
construction and must not be asserted.

Sensitivity was proven, not assumed: overlaying the shouldCompose export that
bin/install.js imports so it always returns false makes a real spawned install
leave autonomous.md's markers in place while the catalog still strips them,
and the row 48 assertion diverges.

Anti-vacuity guards are kept and extended - the comparison set must be
non-empty, must contain a workflow that actually carries markers, must contain
a file the predicate declines to compose, and the install must have emitted a
non-zero file count. The marker-documenting reference case has no instance in
the real tree, so it uses an overlay fixture built with the same technique
workflow-fragments-emission.install.test.cjs already uses.

Renamed to .install.test.cjs so it lands in the install suite it now belongs to.

* test(#3072): retarget the unknown-method assertion off a now-implemented method

tests/gsd-mcp-server.test.cjs used 'resources/read' as its example of an
UNKNOWN JSON-RPC method. The served catalog implements that method, so it now
returns -32602 (no uri supplied) rather than -32601. The remote runner caught
it deterministically on both linux lanes: -32602 !== -32601.

The test's intent is still correct and worth keeping, so it is corrected
rather than deleted or weakened. It now uses 'resources/subscribe', which the
server deliberately does not implement and deliberately does not advertise in
initialize's capabilities, because it never sends the corresponding
notification. That turns the assertion into a real contract - the advertised
capability surface and the implemented method surface agree - instead of an
arbitrary method name a future feature could invalidate the same way.

Swept the rest of the suite for other assertions pinning the newly implemented
methods; this was the only one.

* chore(#3072): backfill changeset PR number 3083

* test(#3072): make the catalog fake fs separator-agnostic for windows

CI caught this on windows-latest (22 and 24): every catalog fixture indexed
ZERO entries, surfaced by the anti-vacuity guards as 'fixture catalog must
actually index resources for this property to mean anything'.

Mechanism: makeFakeFs keyed its dirMap/fileMap on POSIX-joined paths
(${root}/${rel}), while production buildCatalog looks paths up with
path.join, which is backslash-separated on Windows. Every lookup missed,
tryReadDir returned null, and the catalog came back empty.

Production is NOT at fault and is unchanged. The same CI run proves it: on
windows-latest the real-filesystem tests all passed, including 'installer
composition decision matches the served catalog for every file in the real
installed tree' and the row-51 non-vacuity proof against a real spawned
installer. A real Windows fs accepts both separators; the FAKE did not, so the
fake was the unfaithful one and is what changed.

Lookup keys are now normalized unconditionally with .replace(/\\/g,'/') in
readDir and readFile - never path.sep-conditional, never platform-gated. The
row-42/43 injected-fault wrappers got the same treatment, since they compared
raw production paths against POSIX-literal fixtures.

No assertion was weakened, and the anti-vacuity guards that caught this are
untouched - they are the reason this surfaced as a loud failure instead of a
suite that silently asserted nothing on Windows.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Windows CI caught two defects the Linux matrix could not.

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

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

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

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

ef823ca9d9 fix(#2830): propagate a halted plan to its transitive dependents (#3038)
* test(#2830): add failing regression tests for halted-plan dependent blocking

Add tests/fix-2830-halted-plan-dependents.test.cjs covering direct,
transitive (2 and 3 hop), and diamond dependents of a halted plan across
both independent "which plans are incomplete" readers (phase-plan-index's
cmdPhasePlanIndex and findPhaseInternal/searchPhaseInDir), the negative
case (an unrelated decoupled plan stays runnable), and a parity check that
the two readers agree. Uses only modules that already exist at this
commit (gsd-tools.cjs via subprocess, the pre-existing phase-locator.cjs)
so the test file loads and runs cleanly on a fresh clone of this exact
commit. These fail against current behavior: neither reader has any
concept of a halted plan or a blocked_by/runnable view yet.

* fix(#2830): a halted plan no longer leaves its dependents on the runnable work list

A plan that reaches a designed stop still writes a SUMMARY, so both
"which plans are incomplete" readers saw it as an ordinary completion and
reported its dependents as ordinary runnable work — never checking
whether an upstream plan had halted rather than finished.

- New `status: halted` frontmatter value, documented in all four SUMMARY
  templates alongside the existing `status: complete`.
- New shared src/plan-dependency-graph.cts: a single computeHaltPropagation
  pass that both phase.cts's cmdPhasePlanIndex (wave-grouping) and
  phase-locator.cts's searchPhaseInDir (the phase-location primitive, ~50
  dependent symbols across 5 command routers) now call, so the
  two-implementation divergence that caused this bug cannot recur. It
  accepts an optional precomputedOrder so cmdPhasePlanIndex — which already
  runs Kahn's algorithm in computeDependencyLevels for wave assignment —
  passes that order straight through instead of a second traversal;
  searchPhaseInDir (no prior traversal) lets the module derive its own.
  The two small duplicated predicates each reader would otherwise carry
  (is this status "halted"?, which summary file matches which plan id?)
  are centralized in the same module as isHaltedStatus/buildSummaryFileIndex.
- Additive fields only: `halted`/`blocked_by`/`runnable` on
  cmdPhasePlanIndex's plans[] and top level, `halted_plans`/`blocked_by`/
  `runnable_plans` on searchPhaseInDir's result. The pre-existing
  `incomplete`/`incomplete_plans` fields are unchanged in meaning and
  membership.
- execute-phase.md's discover_and_group_plans step now also skips any
  plan whose `blocked_by` is non-empty, reporting it by name with its
  blocking chain, in addition to (not instead of) the existing
  has_summary skip rule.

Extends tests/fix-2830-halted-plan-dependents.test.cjs (introduced in the
prior commit) with direct unit coverage of computeHaltPropagation
(including the precomputedOrder call shape) and a fast-check property
test — both only possible once this commit's new module exists.

Closes #2830

* fix(#2830): surface the halt-aware view from init execute-phase

The adopted work made phase-locator compute halted_plans / blocked_by /
runnable_plans, but cmdInitExecutePhase builds its output by explicitly
enumerating fields, so all three were computed and then silently dropped at
the exact consumer the issue names as regressed.

Forwards them additively -- incomplete_plans and incomplete_count keep their
name, type and semantics byte-for-byte -- and adds the same three empty
defaults to the roadmap-only fallback so the shape is consistent in both
branches. Covered by a new test that drives the real CLI end to end rather
than the locator function, since the locator already worked.

* fix(#2830): fail closed on dependency cycles and stop the templates inviting the defect

Three review findings, all fixed:

- BLOCKER (isolated adversarial). Cycle participants never reach indegree 0 in
  the Kahn pass, so they were excluded from the topological order, never visited
  by the forward pass, and vanished from blocked_by entirely -- i.e. reported as
  runnable. The wave-grouping reader hard-fails on a cycle so it never hit this,
  but the phase-location reader does not, so init execute-phase offered a plan
  depending directly on a halted plan. Reproduced, then fixed in the shared
  engine so every consumer is safe regardless of pre-checks: a node absent from
  the order is now blocked with a deterministic, non-empty named cause. A plan
  silently missing from both blocked_by and runnable is the exact disappearance
  this issue exists to prevent.

- MAJOR (isolated adversarial). All four summary templates showed the field as
  an inline comment on the value line. Frontmatter parsing does not strip
  trailing comments, so an executor copying the templates' own presentation
  wrote a halt that parsed as a non-halted string, silently reproducing the
  original bug. Guidance moved off the value line, and the halt predicate now
  tolerates an unquoted trailing comment.

- HARD standards violation. A test regex-matched child-process stderr prose for
  /cycle/i, which CONTRIBUTING bans. Replaced with the structured failure signal
  plus a differential assertion (same fixture without the cycle edge must
  succeed), so it stays cycle-specific without matching prose.

Also folds the duplicated read-summary-and-check-halted wrapper out of both
readers into the shared module -- centralizing only the predicate left the exact
two-copies-that-drift pattern the module exists to prevent -- and commits the
artifact-types documentation for the new status value.

* test(#2830): stop the property generator hanging the whole suite

The remote runner did not fail -- it hung. Two containers sat in this file for
31+ minutes, and an earlier attempt ran 9 hours before I killed it. The runner
passes --test-timeout=0, so nothing ever reaps it: this would have hung CI
indefinitely, not reported a failure.

Root cause: the DAG generator built edges by rejection --

  from: fc.integer({ min: 0, max: n - 1 })
  to:   fc.integer({ min: 0, max: n - 1 })
  .filter(({ from, to }) => from < to)

With n === 1 both integers are forced to 0, so the predicate is unsatisfiable
and fast-check retries value generation forever. n is drawn from 1..12 and
fast-check biases toward boundary values, so n === 1 is reached almost at once.

This also explains why the failing-first run completed normally while the fixed
run hung: before the fix the graph module did not exist, so the property test
threw on import and never reached generation. It only starts hanging once the
code under test works.

Generates the DAG by construction instead -- `to` is drawn strictly above
`from`, with the degenerate single-node case short-circuited to an empty edge
list -- so no rejection sampling is involved. Switches the import to the shared
fast-check setup so the seed and run count are pinned per CONTRIBUTING, and adds
a bounded regression guard that samples the arbitrary directly, so a future
reintroduction fails loudly instead of hanging.

Verified: the file now completes in 2 seconds, 29 tests started and 29 finished,
zero failures, against an indefinite hang before.

* fix(#2830): restore the depends_on display contract and acknowledge the workflow growth

Full-suite run surfaced two things the focused harnesses could not.

1. Regression of a pinned pre-existing contract (#3785). A refactor routed the
   EMITTED depends_on field through the new dependency resolver, which also
   consults the canonical-prefix map. The original consulted the plan map only,
   so a short canonical prefix passed through verbatim -- '24-01' stayed
   '24-01' rather than becoming '24-01-auth-hardening'. The emitted field is a
   DISPLAY mapping, not the DAG resolution, and #3785 pins that. Reverted with
   a comment recording why it must not use the resolver; full resolution is
   still used for the wave DAG and halt propagation, which is what needs it.

2. The workflow file grew 518 bytes without an acknowledgment, from the
   halt-aware skip rule and the widened parse contract. Acknowledged.

Note on where the acknowledgment landed: the guidance is to add a NEW fragment,
but execute-phase.md is already named by an existing fragment and the linter
hard-fails when two ack sources name the same path. Appending to the owning
fragment, following its own established multi-PR pattern, was the only
lint-clean option.

a987cf2731 chore(#2932): emit a per-invocation section manifest from the init bundle (#2987)
* chore(#2932): emit a per-invocation section manifest from init

Extends the init bundle with a typed per-invocation section manifest so an
invocation loads only the branch guidance it will actually take.

The three flag/state-gated branches in execute-phase.md move into their own
step files; the parent keeps its gsd:section markers wrapping a one-line
on-demand reference, so each section's prose lives in exactly one file and
the parent shrinks 93369 -> 89507 bytes. A new drift-guarded generator
derives the shipped section manifest from those markers, and a new pure
evaluator maps invocation facts to applicable section ids.

The evaluator is a lookup over the frozen WHEN_VOCABULARY, never a parser
(Greenspun's Tenth Rule, ADR-1671:69); a parity test asserts the vocabulary
and the predicate map stay exhaustively in sync.

Closes #2932

* fix(#2932): fail closed on prototype-chain when values

An isolated adversarial review found WHEN_PREDICATES[section.when] was a
bracket lookup on a plain-prototype object, so inherited Object.prototype
members resolved as predicates: "constructor"/"toString"/"valueOf"/
"hasOwnProperty" returned truthy and SILENTLY INCLUDED the section, and
"__proto__" threw an untyped TypeError carrying no .reason. Both violate
the module's documented fail-closed contract, and the manifest is read from
disk at run time so it cannot be assumed trustworthy.

Builds the predicate map on a null prototype and guards the lookup with an
explicit Object.hasOwn check. Adds table-driven coverage for nine
Object.prototype-shaped keys asserting the TYPED reason (asserting only
that it throws would still pass while broken) plus a fast-check property
injecting a hostile value at an arbitrary document position.
