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.

c6ce4d1d9a fix(#2755): resolve the kimi hooks-TOML root per runtime (#3032)
* test(#2755): failing-first coverage for per-runtime kimi hooks root

Install/uninstall filesystem-shape rows over a sandbox HOME (no permission
tricks) plus resolver unit rows. Covers both uninstall directions, which is
where a fix applied only to the install call site would drift.

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

* fix(#2755): resolve the kimi hooks-TOML root per runtime

resolveKimiHooksTomlDir took no runtime argument and hardcoded ~/.kimi, but
both kimi and kimi-code route through the single hooksSurface=kimi-hooks-toml
branch. A --kimi-code install therefore wrote its [[hooks]] block, hook bundle
and CommonJS marker into Kimi CLI's config file, and a --kimi-code uninstall
stripped Kimi CLI's block.

Adds a runtime selector to the resolver -- kimi keeps ~/.kimi + KIMI_SHARE_DIR,
kimi-code gets ~/.kimi-code + KIMI_CODE_HOME, per Kimi Code's own upstream
data-locations and hooks docs -- and passes the runtime at both the install and
uninstall call sites. An omitted or unrecognized runtime still resolves ~/.kimi,
so the exported no-arg contract is unchanged.

* test(#2755): use centralized helpers and add a divergence guard

Review findings, all fixed in-PR:

- The new test block reimplemented runMinimalInstall, createTempDir and
  toPosixPath. Extends runMinimalInstall with optional root/extraEnv instead
  (back-compat: every existing caller passes neither) and uses the centralized
  helpers, per CONTRIBUTING's Use Centralized Test Helpers rule.

- Adds a parity assertion between the capability registry and the resolver: a
  third runtime declaring hooksSurface kimi-hooks-toml would silently inherit
  ~/.kimi, re-creating this very defect. The guard fires the moment those two
  surfaces drift.

- Adds an installer-level test proving KIMI_SHARE_DIR and KIMI_CODE_HOME do not
  interfere when both are set, which only the resolver unit covered before.

* test(#2755): track the kimi-code hooks root in the emitted-artifact gates

The remote runner caught a real ripple: moving kimi-code hooks to ~/.kimi-code
made 31 emitted paths unattributable and 58 emitted hashes unexplained, because
three parallel surfaces keyed on the literal .kimi path.

- HOOK_CONFIG_RELATIVE_PATHS excluded only .kimi/config.toml, so kimi-code's
  config.toml became manifest-visible; it embeds a platform-varying node-runner
  command and must stay out for both products.
- HOOKS_ROOTS, the package.json-marker branch and the synthesized-install-metadata
  pattern each named .kimi only.
- tests/fixtures/install-tree/kimi-code.json still recorded the old paths;
  regenerated via gen:install-tree.

Adds the per-PR drift acknowledgment for the 58 paths whose bytes are unchanged
but whose destination moved - a ripple no source diff can show, since no hook
script was edited.

* fix(#2755): clear production-tree security advisories

The remote runner's npm-integrity gate reported 2 high advisories in the
production dependency tree. My diff touches neither package.json nor
package-lock.json, so these come from the base -- but a red gate is not
something to wave off as pre-existing, so it is fixed here rather than deferred.

Lockfile-only, semver-in-range, via npm audit fix:
  fast-uri   3.1.4  -> 3.1.5   (host confusion via backslash authority introducer)
  ip-address 10.2.0 -> 10.4.0  (three SSRF / trust-boundary bypasses)
  hono       4.12.31 -> 4.13.0 (moderate; reverting it traded a high for a
                                moderate, so the full remedy is taken)

npm audit now reports 0 vulnerabilities at every severity, npm ci installs
clean from the updated lockfile, and the build and the kimi behavior both
re-verified afterwards.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Also in this file:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Review round 2, Minors 2, 3 and 6.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

1c1af70a4b refactor(#2724): delete the committed golden fixtures and size baselines (#2767)
* test(#2724): delete golden-install-parity fixtures, test, and generator

Removes the 19 committed path->hash manifests, the two per-file size
baselines, tests/golden-install-parity.test.cjs, and
scripts/gen-golden-install-parity-zcode.cjs. These were pure functions
of the source tree (ADR-2719); the differential attribution check
(tests/emitted-attribution.test.cjs + tests/emitted-provenance.test.cjs)
is now the sole gate for emitted-artifact propagation.

tests/fixtures/install-tree/*.json and tests/golden-install-tree.test.cjs
are unchanged (ADR-2719 section 7 exception).

Follow-up commits fix the resulting bookkeeping: scripts/ci-test-scope.cjs's
existence guard, .gitattributes, package.json scripts, the emitted-provenance
totality guard's IO, the differential check's baseline acquisition, CI
wiring to publish/restore the baseline artifact, and docs.

* refactor(#2724): make the differential attribution check self-sufficient

Three fixes required to delete the golden fixtures without breaking CI:

- scripts/ci-test-scope.cjs: remove tests/golden-install-parity.test.cjs
  from the three rules that named it. #2759's missingRuleTestFiles guard
  hard-throws at module load if a rule names a test file absent from
  disk, which would break the changes job on every PR the moment the
  fixture-deletion commit landed.

- tests/helpers/emitted-provenance.cjs: loadManifests() read the
  committed golden fixture directory. With that directory deleted at
  every future ref, this would throw at module load forever, taking
  the Phase 2 totality guard down with it. Rebuilt from real installer
  spawns (MANIFEST_FAMILIES + runMinimalInstall + buildParityManifest),
  the same shape emitted-runtime.cjs's currentManifests() already uses.

- tests/emitted-attribution.test.cjs / tests/helpers/emitted-runtime.cjs:
  the real-tree test's baseline acquisition swaps from
  baselineManifestsAtRef(base) (git show at a ref that no longer carries
  fixtures) to resolveBaseline()'s documented precedence: env, then the
  on-disk cache, then an in-job build. The build fallback
  (buildBaselineAtRef, new) checks out base into a throwaway git
  worktree and runs the new scripts/gen-emitted-baseline.cjs there --
  no npm ci needed, since bin/install.js and the test helper shells are
  Node-builtins-only. That script also publishes the baseline artifact
  from CI's push-to-next job (wired in a follow-up commit).

* refactor(#2724): retire the merge-driver bridge and per-file size baselines

The Phase 1 bridge (#2721) is retired now that the artifacts it guarded
are deleted: scripts/git-merge-regen-driver.cjs, its test, and the
'setup:merge-driver' npm script are removed, and the .gitattributes
merge=gsd-regen/linguist-generated block for the three deleted-path
globs is dropped. tests/fixtures/install-tree/*.json keeps its normal
merge behavior, unchanged (ADR-2719 section 7).

scripts/update-size-baseline.cjs and its test are removed: their sole
purpose was regenerating tests/workflow-size-baseline.json and
tests/agent-size-baseline.json, both deleted. The 'size:baseline' npm
script and its step in 'regen:derived' go with it. The per-file
baseline describe blocks in tests/workflow-size-budget.test.cjs and
tests/agent-size-budget.test.cjs are removed for the same reason; the
independent loose-tier hard caps are untouched. The differential
attribution check's size ratchet (tests/emitted-diff.cjs, already
shipped in #2723) is the replacement anti-creep mechanism.

'npm run gen:golden' is replaced by 'npm run gen:install-tree', which
keeps regenerating tests/fixtures/install-tree/*.json (the one artifact
family ADR-2719 section 7 keeps committed); tests/golden-install-tree.test.cjs's
error messages point at the new command name.

tests/golden-parity-single-source.test.cjs's anti-divergence guard
(#2266) is retargeted from the two deleted golden-parity consumers to
their two replacements (tests/helpers/emitted-runtime.cjs and
tests/helpers/emitted-provenance.cjs), which import buildParityManifest
the same way — the divergence risk the guard exists for is unchanged.

Also wires CI: a new publish-emitted-baseline job runs
scripts/gen-emitted-baseline.cjs after a push to next and caches the
result keyed on the sha; the test and test-full jobs restore that cache
on pull_request events, keyed on the PR's base sha, and export
GSD_EMITTED_BASELINE for tests/emitted-attribution.test.cjs's real-tree
test to pick up.

* docs(#2724): flip ADR-2719 to Accepted and update contributor docs

Status: Proposed -> Accepted. Regenerated docs/adr/README.md index.

CONTRIBUTING.md, docs/TESTING-SUITES.md, and CONTEXT.md (RULESET.
EMITTED_ATTRIBUTION, RULESET.WORKFLOW_SIZE_BUDGET, RULESET.
AGENT_SIZE_BUDGET, and the Emitted Artifact Provenance glossary entry)
no longer point at the deleted golden-install-parity fixtures, size
baselines, gen:golden, UPDATE_GOLDEN, or the setup:merge-driver /
git-merge-regen-driver.cjs bridge. Editing shipped content now
requires zero manual fixture regeneration, documented against the
differential attribution check instead of the deleted commands.

* docs(#2724): add changeset for removed golden-parity commands

* fix(#2724): drop stale scripts/update-size-baseline.cjs glossary ref

check-glossary-refs.cjs verifies every backtick-wrapped scripts/*.cjs
token in CONTEXT.md resolves to a real file. The RULESET.
EMITTED_ATTRIBUTION rewrite named the deleted script inside backticks,
which the checker reads as a live reference, not historical prose.

* test(#2724): retarget ci-test-scope tests off the deleted golden test

tests/ci-test-scope.test.cjs asserted specific RULES entries select
tests/golden-install-parity.test.cjs, and that every rule selecting it
also selects both emitted gates. Both premises broke when the golden
test was deleted (#2724): the deleted filename never re-appears in
targeted_tests, and there was no longer a third file for the gates to
travel alongside. Retargeted the two selection describe blocks to
assert tests/emitted-provenance.test.cjs directly (the drift guard the
golden gate's rules were retargeted to), and simplified the third block
to assert the two emitted gates always travel together, without
reference to the golden filename.

* docs(#2724): repoint two contributor how-to guides at the differential check

Both guides told contributors to regenerate a baseline against
tests/golden-install-parity.test.cjs, which #2724 deletes. Repointed
at the differential attribution check (tests/emitted-attribution.test.cjs,
ADR-2719), which needs no manual regeneration step.

* fix(#2724): repair phase6-capstone-conformance's deleted-baseline read

An independent orthogonal review caught a real regression this branch
introduced into a test file the branch's diff never touched:
tests/phase6-capstone-conformance.test.cjs read
tests/workflow-size-baseline.json (deleted earlier in this branch) with
no fallback, so the whole suite would throw ENOENT the moment this
branch landed. The test's actual intent — prove the host-loop workflow
files are real, tracked, non-empty docs — is preserved by asserting the
live byte count via the same shared counter (scripts/workflow-size.cjs)
the size guards already use, instead of a committed snapshot.

Also, from the same review: a stale doc comment in
scripts/workflow-size.cjs still named the deleted
scripts/update-size-baseline.cjs as a consumer, and
buildBaselineAtRef's cleanup in tests/helpers/emitted-runtime.cjs left
two fs.rmSync calls unguarded against masking the primary result/error,
inconsistent with the try/catch already wrapping the git cleanup beside
them. Both fixed. A doc comment was added to baselineFamilyNamesAtRef
explaining why it (and its siblings) are kept despite having no
production caller post-cutover — they still answer real questions
about refs that predate the cutover.

* fix(#2724): repair three real regressions found by remote verification

1. tests/emitted-provenance.test.cjs's two hostile-input tests
   (non-object manifest, unreadable fixture) drove loadManifests(tmp)
   and monkeypatched fs.readFileSync, both premised on the deleted
   fixture-directory read this branch already replaced with real
   installer spawns -- the negative assertions silently stopped firing.
   loadManifests() now accepts injected {families, install, build,
   clean} (defaulting to production values), giving the tests a real
   seam to drive a bad build result and a build failure through the
   ACTUAL loader instead of a reimplementation, and added coverage that
   clean() still runs on both paths.

2. .github/workflows/test.yml's two 'Export GSD_EMITTED_BASELINE'
   steps hardcoded shell: bash, which is wrong on windows-latest (native
   pwsh) and on test-full's macos-latest legs (native zsh per that job's
   own matrix) -- the repo's H1 shell policy (tests/policy-shell-pinning
   .test.cjs) caught it. Replaced the inline bash script with
   scripts/ci-export-emitted-baseline-env.cjs, a plain Node script: a
   bare 'node <path>' command line has no shell-specific syntax, so it
   runs correctly under bash, zsh, and pwsh without a shell override.

tests/phase6-capstone-conformance.test.cjs's deleted-baseline read
(caught by the same remote run, at a commit prior to this one) was
already fixed in d0c3b1242 and is not touched here; verified still
passing after these changes.

* fix(#2724): revive ADR-1610's new-file size cap inside the differential

An isolated review caught a real regression: deleting
tests/workflow-size-baseline.json silently dropped NEW_FILE_CAP
(ADR-1610 Decision point 3, the Codex project_doc_max_bytes anchor)
with no successor. tests/helpers/emitted-diff.cjs's size ratchet
already 'continue's past any file absent from sizeBaseline -- exactly
the files this cap exists to bound -- so a brand-new workflow file
sized 32,769-40,960 bytes passed CI clean and shipped, then risked
silent truncation at the Codex anchor at runtime. ADR-1610 is Accepted
and never referenced anywhere in this branch.

Fix: NEW_FILE_CAP=32768 revived inside emitted-diff.cjs's own
size-ratchet loop, keyed off the SAME hasOwnProperty(sizeBaseline,
name) signal the growth check already computes -- 'new' is exactly
'present in sizeCurrent, absent from sizeBaseline'. Not ack-able,
matching the tier hard caps it sits beside: the fix is extraction, not
an acknowledgment entry. Documented, disclosed narrowing: the pure
differential module cannot see XL_WORKFLOWS/LARGE_WORKFLOWS tiering
(tests/workflow-size-budget.test.cjs's classification), so a
legitimately large new file must extract rather than tier in, one
release earlier than an existing file would need to. ADR-1610 itself is
left unamended -- this restores its decision rather than re-litigating
it.

Also fixes a stale comment plus a redundant real 19-installer-spawn
assertion left over from the pre-injection-seam version of
tests/emitted-provenance.test.cjs's build-failure test, and annotates
3 of 4 stale golden-fixture citations in
docs/reference/host-integration-capability-matrix.md as superseded
(the 4th is an accurate historical PR narrative, left alone).

* fix(#2724): repair three red CI defects on the golden-fixture cutover

Windows-only provenance false attribution (defect A): the `hooks-built`
provenance rule attributed `hooks/<name>.cmd` to itself. Those shims are
Windows-only installer output (ensureCodexHooksJsonSessionStart /
ensureCodexHooksJsonEvent, both in src/runtime-hooks-surface.cts) wrapping
the same-named `.js` hook — no `.cmd` file is ever tracked in the repo, so
the self-attribution resolved to a path that exists on no platform. Only
windows-latest ever emits the key, so this only failed there. Fixed by
special-casing `.cmd` inside the SAME `hooks-built` rule (not a dedicated
rule) — a dedicated rule would match zero paths, and therefore report as a
dead rule, on every non-Windows lane of the same totality guard. `sources`
already supported per-match functions; `transforms` is extended to support
the same shape so the attribution can vary by match within one rule.

Baseline bootstrap was structurally impossible (defect B): `buildBaselineAtRef`
ran `scripts/gen-emitted-baseline.cjs` from INSIDE the base-ref worktree, but
that script is new in this PR and therefore absent at any base ref that
predates it — every call failed closed with "Cannot find module". Fixed by
running the PR checkout's own generator against the worktree via a new `--dir`
parameter, decoupling "which copy of the script runs" from "which tree it
measures" (`currentManifests`/`currentSizes` gained a `repoRoot` override,
threaded down to `runMinimalInstall`'s new `installScript` override). This is
not just a bootstrap fix: a differential needs ONE measurement schema applied
to both sides, or the two stop being comparable the moment that schema
evolves — running each side's own copy would silently reintroduce that risk.
Verified locally end-to-end against real origin/next: resolves a valid
{version, sha, manifests, sizes} artifact with the correct sha and no leaked
worktree.

Changeset placeholder (defect C): `pr: 0` -> `pr: 2767`, which is what let
docs-lint evaluate the fragment for the first time; it already passes
(docs/TESTING-SUITES.md and friends already document the removed scripts).

Also fixed while in this file: an eslint no-unused-vars warning surfaced by
the changed lint run (unused `cleanup` import in
tests/emitted-provenance.test.cjs).

Added regression coverage for both A and B: a cross-platform spot-check that
drives the real hooks-built rule against `.cmd` keys directly (not through a
real Windows install), and a real-tree test that drives buildBaselineAtRef
against a base ref verified (via git cat-file) to lack the generator, both
skipping honestly rather than false-passing when their precondition does not
hold.

* fix(#2724): repair false .cmd byte-provenance and a permanently-skipping regression test

Two isolated-review findings on PR #2767:

- `hooks-built`'s `.cmd` branch attributed the Windows shim's bytes to the
  wrapped `hooks/<name>.js` script, asserting a byte-provenance link that
  does not exist — traced against buildCodexHookWindowsShimIR
  (src/runtime-hooks-surface.cts), only the script's NAME (a literal in that
  same file) flows into the .cmd bytes, never its content. Point `sources`
  at HOOKS_WINDOWS_SHIM_SRC instead, matching the code-derived convention
  used elsewhere in the table. Since `sources` is checked before
  `transforms` in the differential, the wrong mapping silently excused any
  .cmd byte movement caused by editing the wrapped .js file.

- The `buildBaselineAtRef` regression test skipped unless a resolvable base
  ref still lacked scripts/gen-emitted-baseline.cjs — true only until this
  PR merges, after which every base ref carries the file and the test skips
  forever with zero ongoing coverage. Rebuilt hermetically: synthesize the
  missing-generator condition in-place via git plumbing (a throwaway commit,
  child of HEAD, with just that one file removed from a scratch index),
  never touching the real working tree, HEAD, or index, and never depending
  on ambient history or remotes.

* fix(#2724): tolerate the remote runner's dubious-ownership git mount in the emitted baseline path

The runner container mounts the repo at a path owned by a different uid than
the process running the suite, so git's dubious-ownership protection refuses
every git operation there. GitHub Actions never hits this because
actions/checkout registers the workspace as safe automatically; this
runner's container does not.

buildBaselineAtRef is the production build-fallback the sole remaining
emitted gate depends on (resolveBaseline's in-job-build leg), not just a
test helper, so the fix is in the shared git() wrapper (emitted-runtime.cjs)
that every caller — resolveChangedPaths, resolveBase, buildBaselineAtRef's
worktree add/remove/prune, and the hermetic regression test added in the
prior commit — funnels through, plus gen-emitted-baseline.cjs's own
rev-parse (now reusing that same wrapper instead of a second execFileSync,
so the fix has one source of truth). Each call declares -c
safe.directory=<the exact directory it already operates on>, never the *
wildcard.

Audited every other helper on this surface (emitted-diff.cjs,
emitted-baseline.cjs, install-shared.cjs) for the same gap: none of them
shell out to git at all.

44707c2c5e fix(#2757): attribute transform-driven emitted changes and reclassify agents-verbatim (#2760)
* fix(#2757): let derived provenance rules attribute a transform change

The Phase 2 provenance table (#2722) could only explain a moved emitted
path via its `sources`, so a `kind: 'derived'` artifact whose TRANSFORM
code changed (not its source) was unattributable by construction: 16
emitted agents/*.toml moved by PR #2566's runtime-artifact-conversion.cts
change, with zero agents/*.md in the diff.

Adds an optional per-rule `transforms: string[]`. A moved emitted path
now attributes via its source OR its transform, reusing sourceSatisfiedBy
so exact/prefix matching stays identical for both. Declared narrowly on
agents-toml-derived and agents-verbatim (the two families verified to
route through the same conversion pipeline) as
src/runtime-artifact-conversion.cts, src/install-effort-resolver.cts, and
src/model-catalog.cts — never bin/install.js, which would be a blanket
escape hatch spanning every installer concern.

Also corrects agents-verbatim from kind:'identity' to kind:'derived':
measured against origin/next's own fixtures, the same agents/<name>.md
hashes differently per runtime (e.g. codex vs claude), which a true
verbatim copy cannot do. Verified empirically by installing every
runtime and diffing against the raw repo source — none reproduce it
byte-for-byte; every one rewrites frontmatter and the hardcoded
.claude/ self-reference, and claude additionally gets an effort: line
injected. A new assertNoIdentityTransforms invariant rejects an
identity rule that declares a non-empty transforms list.

Closes #2757

* docs(#2757): flag PR #2566's transform-role files for later verification

src/agent-tools-contract.cts (added by #2566, absent on next) and
src/agent-install-check.cts (modified +112/-1 by #2566, read-only today)
were reviewed for prospective inclusion in AGENT_TRANSFORM_SRCS.

Excluded for now: the nonexistent file would fail this fix's own
"every declared transform path exists" hygiene test, and the modified
file's future role cannot be verified without the unmerged PR's diff.
Documents the reasoning, the interim ack-file safety net, and the
verification method to apply once these files stabilize, so the next
PR touching them has a pre-scoped one-line fix rather than a silent gap.

0f60266042 fix(#2723): reconcile emitted manifest families as a set, not a count (#2750)
* fix(#2723): reconcile emitted manifest families as a set, not a shared count

EXPECTED_MANIFEST_COUNT was a single literal 19 asserted against both the
baseline (built at the base ref) and the current tree (built at PR HEAD).
Those sides legitimately differ by one family whenever a PR adds or removes
a runtime, so no value satisfied both: 19 rejected the current side, 20
rejected the baseline side. Every runtime-adding PR was hard-blocked.

Replace the shared literal with three independent signals - the derived
family set, the recorded fixture set, and the families present at the base
ref - reconciled as sets in both directions. A family may appear or vanish
only when the diff plausibly touches the runtime registry, and the failure
names the family rather than a count. An absolute floor catches the
uniformly shrunken universe a same-count self-check passes vacuously.

Found by tracing #2005 (Qoder runtime) through the gate during the ADR-2719
dual-run window.

* fix(#2723): read the baseline family set from the ref, not HEAD's registry

Review found three defects in the first cut.

Blocker: baselineManifestsAtRef enumerated MANIFEST_FAMILIES, which is imported
at module load and therefore describes PR HEAD. A runtime REMOVED by the PR is
already absent from that list, so the base ref was never asked for it, the
baseline silently omitted a family that genuinely existed, and the dropped-family
check could never fire in production - while its unit tests passed, because they
inject the baseline directly. Enumerate from the ref with git ls-tree instead.

Also: narrow the registry-signal set to the two surfaces that actually define the
family set, since every extra path widens what excuses an unattributed delta; drop
the ack bypass, which was a one-sided escape hatch making removals easier to wave
through than additions; and gate the derived/fixtures inputs so malformed values
return a verdict rather than an unhandled TypeError.

* fix(#2723): filter prototype-shaped family names read from git output

baselineFamilyNamesAtRef derives object keys from git ls-tree output rather
than a trusted constant, so a fixture committed as __proto__.json would turn
the manifests[name] assignment into a prototype write. Compared inline rather
than through a Set, which is the form the prototype-pollution analysis
recognizes.

* fix(#2723): require an exact capability path depth and make the ref test hermetic

The remote runner went red on both linux lanes with two real defects.

The capability signal matched by prefix+suffix, so 'capabilities/capability.json'
(no runtime segment) and 'capabilities/a/b/capability.json' (wrong depth) both
attributed a family change and would have excused an unattributed delta. Anchored
to an exact single-segment pattern.

The ref-derivation test reached for this repo's root commit, which is not stable:
the remote runner shallow-clones, so rev-list --max-parents=0 returns the grafted
boundary carrying every fixture, and this repo has two root commits locally anyway.
It now builds its own git repo containing a family absent from the current registry
- the real discriminator, and one the root-commit version could never assert.

Lint then caught a third: the test called t.after() without declaring t.

* fix(#2723): stop asserting ref enumeration against the ambient checkout

The remote runner returned [] for the repo's own HEAD while every hermetic
temp-repo assertion in the same test passed. That is this function's documented
behavior when git cannot read the ref - the runner works from a shallow clone
under a bind-mounted workdir - so the assertion was testing the checkout rather
than the code.

Dropped it. The temp repo already proves the property that matters, and proves it
more strongly: it contains a family absent from the current registry, which a
registry-derived implementation could never report. The ambient path stays covered
by the real-tree test, which skips explicitly when no base ref is resolvable.

A git failure is not silently permissive downstream: baselineManifestsAtRef returns
null on an empty family set and the real-tree test asserts the baseline is non-empty.

1f6822ccba test(#2722): emitted-artifact provenance table with a totality guard (#2735)
* test(#2722): emitted-artifact provenance table with a totality guard

Adds the declarative emitted-path -> source-path table that ADR-2719 §2
specifies, plus the totality guard that keeps it honest. Phase 2 of #2719.

Every emitted path across all 19 committed golden-parity manifests (8,524
paths) must match exactly one rule. Zero matches, two matches, and a rule
matching nothing are all hard failures, so a new emitted family fails the
build loudly instead of passing through unattributed.

The measured surface is larger than #2722 estimated from claude.json alone
(26 top-level families across 19 runtimes, not 13), which is itself what the
totality guard exists to surface. It resolves to 19 rules.

Building the table caught three false attributions that were total but
resolved to repo files that do not exist -- Copilot's `<name>.agent.md`
rename, Kimi's code-literal `agents/gsd.{yaml,md}` root agent, and Copilot's
`hooks/gsd-session.json` registration. The "every attributed source exists"
test is therefore a first-class gate, not a nicety.

Notable correctness decisions:
- Emitted shapes are hard-coded; deriving them from the installer would make
  the guard tautological (it would follow any installer change silently).
  Only source paths read a first-party descriptor, and only where the
  descriptor is the sole declaration (hostBehaviors.nativePlugin.source).
- Emitted skills attribute to commands/gsd/*.md, NOT the repo skills/ dir --
  that directory is generated from commands/gsd by gen-plugin-skills.cjs, so
  attributing to it would be false attribution that still passes totality.
- Attribution is keyed on (rel, runtime): plugins/gsd-core.js has different
  sources for opencode and kilo.
- Rule order carries no semantics (property-tested), since exactly-one
  matching is enforced rather than first-match-wins.

Nothing here reads a git diff, builds a live manifest, or touches a fixture;
the differential check, drift-ack file and size ratchet are #2723.

* docs(#2722): record the delivered provenance table in the CONTEXT.md glossary

The `### Emitted Artifact Provenance` entry landed in #2721 describing the
table as future work. Phase 2 delivers it, so the glossary now records what
actually exists and the invariants #2723 must preserve:

- where the table lives, its rule count, and that it is total over all 8,524
  emitted paths across the 19 manifests
- dead-rule detection, so table rot is loud in both directions
- the corrected surface measurement (26 families, not the 13 estimated from
  claude.json alone)
- the two invariants #2723 inherits: shapes hard-coded (deriving them would
  make the guard tautological), and attribution keyed on (rel, runtime)
- the skills/ false-attribution trap, and that totality does NOT catch a
  wrong-source rule — the source-existence assertion is what does

* test(#2722): close five review findings on the provenance table

Two orthogonal review passes plus an isolated adversarial reviewer returned
findings at minor..major. All fixed; no blockers were raised.

Standards axis (CONTEXT.md:456, RULESET.TESTS.guard-toplevel-readFileSync):
- module-level loadManifests() threw at require time before any test()
  registered, turning a missing fixture dir into an opaque crash instead of
  one named failure. Now a memoized lazy accessor.
- matchRules and assertTotality each carried their own copy of the matching
  loop; assertTotality now calls matchRules. That is the #2266 divergence
  class, and two copies could let the guard and the attributor disagree.
- named the corpus stride constant; dropped an inline require.

Spec axis:
- the CONTEXT.md glossary carried a "26 families" figure that is not
  reproducible from the code and that no test pinned -- a hand-maintained
  number in permanent canon, i.e. exactly the silent drift this epic exists
  to end. All volatile counts are now removed from the glossary, with the
  reason stated inline: the guard recomputes them every run, so they belong
  in a failure message, not in prose. No test was added to pin the count,
  because that would rebuild the brittle committed number we are deleting.

Isolated adversarial review:
- `.+` tail captures let a `..` segment reach a constructed source path that
  resolves outside the repo. Not live-exploitable (fixtures are committed and
  the only consumer is an existsSync probe) but Phase 3 feeds these strings
  into a diff-consuming check, so assertSafeRelPath now fails closed once, in
  matchRules, rather than per-rule.
- attributeEmittedPath's ambiguous-match branch was never exercised; only
  assertTotality's parallel path was. Now tested directly.
- sampleLimit's truncation branch had no limit-1/limit/limit+1 coverage.
- the fast-check property could not fail for the reason it was named for.

That last one took two attempts and is the one worth reading. The property
hand-rolled its shuffled side from the per-rule matchOne primitive, which is
order-independent by construction, so it held for reasons unrelated to the
shipped matchRules. Routing it through the real matchRules was still not
enough: on an unambiguous table, first-match-wins and collect-all return
identical results for every path (measured: 0 of 190 corpus paths differ).
Order can only matter where more than one rule matches, so the property now
also asserts that an intentionally ambiguous table reports BOTH hits as a set
under every permutation. Verified by mutation -- injecting a `break` into
matchRules makes it fail, and restoring makes it pass.

Enabling all of the above: matchRules and attributeEmittedPath now take an
injectable rules table, so tests can drive the real code path instead of
re-implementing it by hand.
