9e4f0e99ad fix(#3631): exclude only __pycache__-resident bytecode from the consent digest (#3650)
* test(3631): failing-first coverage for bytecode-cache in the consent hash

bundleContentHash digests a walk with no exclusion, so a routine 'python3 -m unittest'
inside a Python-backed capability bundle writes __pycache__ under the bundle, the
recomputed hash stops matching the consent record, and the capability silently goes
inactive — no error, no warning, and loop render-hooks then omits its step and gate.

Two distinct triggers, and the second is the sharper one: collectBundleEntries pushes a
{kind:'dir'} entry for EVERY directory and the digest emits a TAG_DIR marker for it, so an
EMPTY __pycache__/ flips the hash before a single .pyc is written. A fix filtering only
*.pyc would leave that live. Verified by execution against the built lib: 5 of 7 probe
rows diverge from intent today, including the empty-directory row.

The anti-regression rows are the point of the shape: editing a real scripts/m.py and
adding node_modules/pkg/index.js must BOTH still change the hash. node_modules is
deliberately not excludable — its contents are required at runtime, so dropping it from
the digest would stop consent binding executable content. The symlink row pins ordering:
exclusion must apply after the lstat fail-closed rejection, never before.

* fix(3631): exclude derived bytecode caches from the consent digest

RED proven at e5ba8f1fe on the remote runner: 8 failures, exactly the rows predicted to
fail, with the four anti-regression rows already green.

collectBundleEntries now skips a hardcoded, gitignore-independent set from the DIGEST:
basenames __pycache__, .pytest_cache, .DS_Store, and any .pyc/.pyo file. Matching is
byte-exact on the raw Buffer name (the walk never utf8-decodes) and case-sensitive, so the
digest does not vary with how a name happens to be spelled on a case-insensitive volume.

Three properties were preserved deliberately, each pinned by a test:

  - The filter runs AFTER the lstat symlink/non-regular fail-closed rejection. Filtering
    first would have turned the exclusion into a way to smuggle a symlink past the check;
    a symlink named x.pyc still throws.
  - Excluded entries still count toward BUNDLE_MAX_FILES and BUNDLE_MAX_TOTAL_BYTES. The
    caps guard the WALK; the digest answers a different question, and exclusion must not
    become an unbounded-bytes hole.
  - An excluded DIRECTORY is neither emitted as a TAG_DIR marker nor recursed into. The
    directory marker was the sharper half of this bug: an empty __pycache__ flipped the
    hash before any .pyc existed, so a *.pyc-only filter would have left it live.

The issue proposed either a gitignore-aware walk or a list including node_modules. Both
are rejected. A consent binding must not delegate its scope to a .gitignore the bundle
author does not control — one line there would drop arbitrary executable content out of
the hash. And node_modules holds code that is required at runtime; excluding it would stop
consent binding executable content, turning a usability bug into a supply-chain hole. What
makes __pycache__ different is that CPython validates each .pyc against its sibling
source, which remains hashed, so a real code change still invalidates consent.

Docs: CONTEXT.md's 'EVERY regular file AND directory' claim is corrected in place.
ADR-2363's residual-gap section said the walk had 'no exclusions' — per
docs/adr/README.md ('ADRs are append-only') that is corrected by a dated amendment rather
than an in-place edit. Its D4 argument is unaffected: skill bodies are .md and stay bound.

Fixes #3631

* fix(3631): narrow the digest exclusion after two isolated security reviews

The first cut of this fix passed the full suite and was still wrong. Both orthogonal
reviews rejected it, and the second one found a hole that has nothing to do with Python.

HIGH — an excluded DIRECTORY was 'continue'd before recursion, so its whole subtree was
permanently outside the digest. Declared hook script paths allow '_', '.' and '/' with no
directory or extension rule, so hooks:[{script:'__pycache__/run.js'}] installed, executed
via node, and its bytes could be rewritten forever without moving the hash. Ship benign
v1, collect consent, then own the machine. No Python involved.

FALSE RATIONALE — the justification I wrote into the code, CONTEXT.md, the ADR amendment
and the changeset claimed CPython validates a cached .pyc against its sibling source, so
the source staying hashed kept consent honest. That is not true, and I proved it by
execution rather than argument: default timestamp invalidation compares only the source's
mtime and size, both settable by anyone who can write the bundle. A forged pyc ran while
the .py was byte-identical.

Also wrong: '*.pyc' matched anywhere, but a legacy sourceless scripts/x.pyc IS importable,
so excluding it was a live vector.

Narrowed to what is actually defensible:
  - a DIRECTORY named __pycache__/.pytest_cache has only its TAG_DIR marker suppressed;
    the walk still recurses and hashes every non-excluded child.
  - .pyc/.pyo are excluded ONLY when the parent basename is exactly __pycache__.
  - a regular FILE named __pycache__, and a DIRECTORY named x.pyc, stay bound.
  - declared hook paths containing a __pycache__/.pytest_cache segment or a .pyc/.pyo
    basename are now rejected in both validator copies — a file named .pyc can contain
    perfectly valid JavaScript, so the exclusion must not be reachable from a declared
    surface.

Accepted residual risk, stated plainly in ADR-2363 and CONTEXT.md instead of explained
away: a forged __pycache__/mod.pyc matching an unmodified, still-hashed mod.py executes
without moving the digest. Before this change that write was detected. It is accepted to
stop routine bytecode caching from silently deactivating capabilities, and it is bounded —
the attacker needs post-consent write access, everything outside __pycache__/*.pyc stays
hashed, and no declared surface can point into the excluded space.

Known limitation, not papered over: .pytest_cache CONTENTS still move the digest. Only the
directory marker is suppressed. Excluding that subtree would reopen the HIGH finding.

Refs #3631

* fix(3631): drop the .DS_Store exclusion and pin what the caps actually bind

Second round of isolated review findings. The hardening closed the two original holes —
both re-reviews confirmed that by execution — but it introduced a new one of the same
shape, and left three claims unbacked.

HIGH, self-inflicted: .DS_Store was excluded from the digest at any depth, but the hook
path validator was hardened only for __pycache__/.pytest_cache/.pyc/.pyo. So
script:'hooks/.DS_Store' was ACCEPTED, runnableHookCommand emits the bare quoted path for
a non-.js name (the branch .sh hooks already use), and capability-source copies it with
its mode bit intact. Ship it +x with a benign shebang, take consent, then rewrite it
forever — the digest never moves. Fixed by DELETING the .DS_Store exclusion rather than
teaching the validator about it: .DS_Store has nothing to do with this issue's Python
bytecode symptom, and an excluded filename is a permanently unhashed name. The narrower
the exclusion, the smaller the hole.

The residual-risk bound in ADR-2363 and CONTEXT.md claimed declared surfaces cannot reach
excluded space. That is false and is now stated correctly: node resolves an unregistered
extension through the default .js handler, so a hashed, consent-covered hooks/run.js that
requires '../__pycache__/mod.pyc' reaches it in one hop. The validator guard raises the
bar for DECLARED surfaces; it does not contain the risk. The two bounds that are real —
post-consent write access required, everything outside __pycache__/*.pyc still hashed —
are kept.

The BUNDLE_MAX_FILES boundary test had gone vacuous: it padded with root-level *.pyc,
which the hardening made non-excluded, so it no longer proved anything about excluded
entries while the ADR claimed the caps were test-pinned. It now pads __pycache__/f{i}.pyc,
with the arithmetic re-derived by execution (capability.json + the still-counted
__pycache__ dir + N). BUNDLE_MAX_TOTAL_BYTES had zero coverage at all and is now pinned by
a sparse 32 MiB __pycache__/big.pyc that must still trip the size cap — the test that
proves exclusion did not become an unbounded-bytes hole.

Added the parity assertion CLAUDE.md's Generative Fix Divergence rule requires for the two
isSafeHookScriptPath copies, and proved it can fail: mutating one BUILT copy to drop .pyo
made the parity check report the divergence. Also pinned semantics that were correct but
untested and would have survived mutation — __pycache__/sub/x.pyc stays hashed (the parent
resets to sub, which is the recursion threading itself), .pytest_cache/y.pyc stays hashed,
and .pyo in both directions, which was a free surviving mutant.

Changeset rewritten: it still described the rejected wholesale-exclusion semantics.

3f6b063fbb chore(#2799): invoke_reviewers and write_reviews iterate declared lanes (#2861)
* chore(#2799): resolve reviewer lanes into executable invocation plans

Phase 5b of ADR-2782. Adds the resolver and runner that let invoke_reviewers
iterate declared lanes instead of hand-authored per-CLI bash.

Five additive descriptor amendments, each forced by a lane that ships today:
- LaneHandler gains 'opencode' — the lane rebuilds its review from assistant
  text parts of a --format json stream; a plain stdout copy re-breaks #1936.
- modelConfigKey — antigravity's key is review.models.agy, not .antigravity,
  so resolving by slug silently dropped a configured model.
- defaultHost/fallbackModel — Phase 4 federated every *_host with a default of
  empty string; the real fallback only existed in the bash.
- args becomes an argv template with a closed four-placeholder vocabulary.
  Positional splicing produced 'codex --model M -o F exec --ephemeral', which
  is not a valid invocation: codex injects in the middle, twice.
- kimi-code lane, with the bounded command-capability probe (needle
  --output-format) that tells Kimi Code from the legacy python kimi-cli.

Parity gate re-pointed: the workflow-text families it scanned are the text this
phase deletes, so they are replaced by descriptor-to-registry parity plus an
anti-parity check that no bespoke leg returns.

jq, curl and external timeout/gtimeout all drop out of the review path.

Refs #2782

* chore(#2799): add review-lane query surface and widen the manifest vocabulary

Adds the gsd-tools 'review-lane' route (plan/invoke/sections) the workflow
loops over, projects all twelve lanes into their capability manifests, and
widens capability-validator for the amendments.

opencode admitted to VALID_LANE_HANDLERS under the second arm of the enum's
own admission rule: one lane, justified by a documented upstream defect data
cannot express (#1936 — the agent can end its turn with zero output tokens and
--format default then drops the assistant text entirely).

Two bugs caught by an end-to-end stub run and fixed here:
- loadConfigResolved returns a provenance wrapper, not the config; using it
  directly resolved every key to undefined, which reads as 'nothing
  configured' and silently dropped every model override.
- hasBinary used shell:true with an args array (Node 26 DEP0190). Replaced
  with a PATH scan that spawns nothing at all.

Refs #2782

* chore(#2799): iterate declared lanes in invoke_reviewers and write_reviews

Replaces the eleven hand-authored per-CLI bash legs with a loop over resolved
lanes, and renders REVIEWS.md sections from each lane's declared
reviewsSection instead of thirteen hardcoded headings. review.md drops from
1104 lines to 507 (61KB to 28.7KB).

Parity gate re-pointed, as agreed: the leg-marker and section-heading families
scanned exactly the text this phase deletes, so they are replaced by
descriptor-to-registry parity in both directions, plus an anti-parity check
that fires if a bespoke leg is ever re-added. Enum, emitting sites and the
Object.keys lock moved together.

The budget-trim helper is hoisted out of the Ollama leg: it was always
lane-agnostic, and any lane may now declare a promptBudgetKey.

Refs #2782

* feat(#2799): bind the consented egress host and re-verify it at invocation

Completes ADR-2782 D5. Rule 1 was recorded in the ADR as delivered by Phase 3
but was not implemented: ConsentRecord had no host field and nothing in the
tree bound one, so this phase's rule-4 comparison had no baseline.

ConsentRecord gains an OPTIONAL reviewerHost. Optional is the whole design:
isValidConsentRecord does not require it, so every record already on disk
stays valid and no re-consent storm fires (D4 rule 5). It is deliberately
excluded from disclosureSignature — the loader has no config resolver, so
folding a config-derived value in would make loader and lifecycle compute
different signatures for the same manifest and re-prompt forever.

Install resolves hostConfigKey (falling back to the lane's declared
defaultHost, which is what the invocation path uses) and records it.
Invocation re-resolves and blocks on mismatch rather than silently
redirecting. Absence allows: no record, or a record predating the field,
means nothing to compare — denying there would break every existing
local-model user on upgrade.

Refs #2782

* test(#2799): cover the resolver, runner and handlers; retarget the parity suites

Adds the golden invocation-plan table (one row per shipped lane, derived from
the bash legs rather than the descriptor types) plus runner coverage for the
probe, empty-output policy, the three handlers and the egress check.

Retargets the existing suites onto the new contract: descriptor-to-registry
parity, the anti-parity check, the opencode handler, and the twelfth lane.

Two corrections found by running them:
- modelConfigKey was required; that breaks D4 rule 2, since a reviewer
  manifest authored before this phase would fail validation on upgrade. It is
  optional, read as null when absent.
- the antigravity non-zero-exit test pre-seeded the transcript, which asserted
  that a STALE entry leaks through — the exact bug the watermark prevents. The
  spawn now appends, as the real tool does.

Refs #2782

* fix(#2799): restore agy --add-dir and the self-report prompt in the handler

Retargeting the three legacy reviewer suites off the deleted bash surfaced two
real regressions in the port, both #2176:

- --add-dir was dropped. Without it agy's permission context never receives the
  cwd repo, so the agent anchors on its own scratch dir and reviews the plan
  text in isolation — the exact failure the Review Instructions forbid. It is
  capability-probed, because an older agy rejects the unknown flag outright and
  a lane that fails to start is worse than one running on the prompt anchor.
- the prompt lost the clause mandating a REVIEWED-WITHOUT-REPO-ACCESS
  self-report, which is what makes a blind review distinguishable from a
  grounded one. antigravity now builds its own prompt variant.

Also ports the #2073 mode-2 cli.log diagnostic, which was dropped: a pinned
model that 404s exits 0 with empty stdout AND an empty transcript, so agy's own
log is the only evidence that anything failed.

The three suites now assert against the plan and the handler instead of
matching fence text, so they no longer need allow-test-rule exemptions.

Refs #2782

* docs(#2799): document the declared lanes, the new flag, and dropped prerequisites

COMMANDS.md gains --kimi-code and replaces the jq-prerequisite paragraph,
which is now false: no lane requires jq, curl or an external timeout. Adds the
changed-egress-destination behavior, since a blocked lane is something a user
can hit.

CONFIGURATION.md records that the model config key is declared per lane rather
than derived from the flag — antigravity's is review.models.agy — and adds
review.models.kimi-code.

reviewer-instances.md now routes an instance through its lane's single
invocation seam instead of a copied per-adapter bash block, which is what lets
a cross-cutting fix reach instances for free. That required implementing the
--model/--agent/--as flags it documents; --model re-resolves through the lane's
argv template rather than splicing, so the flag lands where the lane declares
it rather than ahead of a subcommand.

CONTEXT.md glossary gains both new modules.

Refs #2782

* chore(#2799): drop the stale emitted-drift acknowledgment

The only entry was #2797's, acknowledging COMMENT-ONLY GROWTH in review.md.
That file now shrinks by ~32KB and every emitted hash that moved is
attributable to this diff, so the ack no longer explains anything. Removing
the last entry means removing the file: its presence is the alarm, and an
empty one signals nothing.

Verified by deleting it and re-running the attribution and provenance gates
plus lint:ci — all green without it.

Refs #2782

* docs(#2799): record the Phase 5b vocabulary widenings in ADR-2782

Five additive amendments, each forced by a lane that ships today, plus two
corrections the phase had to make rather than work around:

- D5 rule 1 was recorded as delivered by Phase 3 and was not implemented, so
  this phase's rule-4 comparison had no baseline. Recorded because an ADR
  asserting a rule was delivered is exactly what stops a later phase checking.
- The DEFECT.GENERATIVE-FIX gate is re-pointed: its workflow-text families
  scanned the text this phase deletes.

Also records that D7's 'skip the probe where no bounding mechanism exists'
carve-out is obsolete — in practice it meant the Antigravity lane ran unbounded
on every stock macOS host, which ships neither timeout nor gtimeout.

Refs #2782

* fix(#2799): close four defects found by adversarial review

Two confirmed bugs, both reproduced before fixing:

- resolveLanePlan was not total. An openai-http lane with a missing or
  non-object invoke dereferenced inv.hostConfigKey and threw, contradicting
  the module's own documented contract; the spawn branch guarded correctly and
  the http branch did not. The CLI seam resolves every selected lane in one
  map, so one malformed overlay manifest would have aborted the whole review
  rather than dropping its own lane. Guarded, plus a per-lane try/catch at the
  seam so a throw can never take down siblings.
- A reviewer-instance model was silently dropped for any lane declaring
  modelConfigKey null (cursor, qwen, coderabbit). reviewer_instances validates
  that cli is a known slug but never that the slug accepts a model, so a user
  could configure one, get a clean run, and never learn a different model
  reviewed their plan. Now warns explicitly.

Two hardening fixes:

- The slug is concatenated into artifact paths, so LANE_SLUG_RE is enforced in
  the resolver rather than inherited from a validator that does not run on this
  path — the module documents itself as the overlay-manifest trust boundary, so
  it should not depend on someone else having checked.
- normalizeHost mangled a scheme-less value: new URL('localhost:11434') parses
  with an empty hostname, so it became 'localhost://11434' and was compared and
  requested as if real. An empty hostname now means not-a-URL.

Also documents the one gap that cannot be closed here: the antigravity
watermark is keyed by workspace, so two concurrent reviews of the same repo
share a transcript. agy exposes no per-invocation id to filter on, so the
handler now states which half of its never-stale guarantee actually holds.

Refs #2782

* test(#2799): retarget the remaining eight review.md-asserting suites

The remote runner found 37 failures the local sweep missed (it hit the shell's
two-minute cap before reaching these). All eight extract per-CLI bash from
review.md that this phase deletes; each protects a real invariant, so each is
retargeted onto the plan, the runner or the handler rather than removed.

Three real defects surfaced by doing so:

- effort args never reached ANY lane. model-resolver.cjs exports no
  resolveExecution, so effortFor silently returned [] every time. Restored by
  calling the same bounded resolve-execution query the bash legs used — and
  NOT with --raw, which prints the resolved effort rather than the picked
  field, so claude got 'low' instead of '--effort low'.
- the timeout guidance lost 'a silent empty output is a timeout kill, not a
  crash' — the operator note that exists because of the Codex 0xc0000142
  misdiagnosis. Restored.
- the opencode handler dropped EMPTY assistant text parts. The shipped jq was
  , and  only substitutes for false/null — an empty
  string is truthy in jq and contributed a blank line. Found by a property
  test shrinking to ['', ''].

The opencode property suite no longer spawns jq at all, which deletes the
#2099 hang mechanism it was architected around rather than mitigating it.

Refs #2782

* fix(#2799): register the two new generated modules, and untrack them

The remote runner caught build output committed to git. Both new modules
compile from src/*.cts into gsd-core/bin/lib/*.cjs, and every sibling generated
that way is gitignored and eslint-ignored (ADR-457) - including Phase 1's own
review-lane-descriptor.cjs. Mine were neither, so repo-invariants' "each
bin/lib/*.cjs is linted xor ignored according to migration state" failed.

Registered both in .gitignore and eslint.config.mjs alongside the Phase 1
module, and dropped them from the index. Nothing about the shipped behaviour
changes; the artifacts are rebuilt by build:lib.

This is the new-.cts-module registration ripple, and it is the one part of it I
had not completed - the CONTEXT.md glossary and the inventory manifest were
already done.

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

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

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

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

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

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

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

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

Closes #1740

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

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

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

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

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

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

bcc5a6d1ba fix(#1634): honor capability hook matcher and node-prefix command (#1638)
* fix(#1634): honor capability hook matcher and node-prefix command

Capability hook install (applyCapabilitySharedEdits) wrote each settings.json
hook entry with no `matcher`, so a tool-scoped hook fired on every tool (a
fail-closed guard could then block the whole session), and emitted a bare
single-quoted script path so a .js-family hook from a git/tarball source
without +x failed with Permission denied on every matching call.

- Pass through an optional declared `matcher` (entry-level sibling of `hooks`);
  absent => omitted (match-all), so existing shipped capabilities are unchanged.
- Validate `matcher` in the declaration (non-empty string, no control chars).
- Emit `node <quoted-path>` for .js/.cjs/.mjs hooks (mirrors first-party);
  .sh and others keep the bare quoted path (unchanged).

Root cause: the manifest hook schema (validator rule C4) was {event, script}
only with no matcher, and applyCapabilitySharedEdits never read or wrote one;
the command used shellSingleQuote(absScript) with no node prefix.

Regression tests fail-first on both defects (matcher dropped; bare path) and
pass after the fix; #1460 command assertions updated for the node prefix.

* chore(#1634): backfill changeset pr:1638

* fix(#1634): resolve lint and windows CI failures

- validator: replace the control-character range regex with a char-code loop.
  The literal /[\x00-\x1f\x7f]/ tripped ESLint's no-control-regex rule; char
  codes are equally precise and lint-clean. Behavior unchanged (still rejects
  matchers containing ASCII control characters incl. DEL).
- test: gate the executable-bit precondition on POSIX. Windows fs does not
  honor POSIX write modes (a 0o644 write reads back as 0o666), so the
  precondition is meaningless there and failed the windows-latest lane. The
  node-prefix assertion — the actual fix — is platform-independent and still
  runs everywhere.

* docs(#1634): amend ADR-894 for optional lifecycle hook matcher

The `role: "feature"` `hooks[]` entry now carries an optional `matcher`
(settings.json tool-scoping pattern: exact/pipe/wildcard/regex). Document
the field in the §2 schema table and record a Grilling-amendments entry:
the install path projects a declared matcher onto the emitted settings.json
hook entry (absent = match-all, so shipped capabilities are unchanged), and
per-runtime matcher projection (ADR-857 D8) stays a separate concern. This
amendment ships with the fix that introduced the field rather than as a
follow-up.

* docs(#1634): record WINDOWS-POSIX-MODE-BIT-ASSERT defect in CONTEXT.md

Capture the CI failure pattern from #1634/PR #1638 so it is not repeated: a
test that writes a file with a POSIX mode and then asserts statSync().mode
& 0o777 === <octal> passes on macOS/Linux but fails on windows-latest
(Windows fs does not honor POSIX write modes — reads back 0o666). Added as a
machine-greppable DEFECT predicate (symptom/examples/detect/fix-forward/
prevention) next to DEFECT.WINDOWS-TEST-PORTABILITY, with the fix-forward:
gate the mode-bit precondition on process.platform !== 'win32' and keep the
platform-independent behavioral assertion running everywhere.

0d56f544d2 feat(#1435): capability matrix (generated + drift-guarded) + trust-model doc consolidation (#1458)
* feat(#1435): capability matrix (generated + drift-guarded) + trust-model doc consolidation

ADR-1244 Phase 6. Adds the capability matrix reference, generated FROM the committed registry so it
can never drift from the actual capability set:
- scripts/gen-capability-matrix.cjs (--write / --check); --check is a CI drift guard.
- tests/capability-matrix-sync.test.cjs (4 tests): drift guard, buildMatrix==committed, every cap
  present, no placeholders.
- docs/reference/capability-matrix.md regenerated from the registry (release-stable: shows engines.gsd,
  omits the lockstep per-cap version that would churn the file every release).
- Consolidated the duplicate trust-model doc: deleted docs/explanation/the-capability-trust-model.md,
  merged its content into capability-trust-model.md, redirected ~10 references; no stale links remain.
- Diataxis verification (now that gsd capability is a real command): corrected the matrix's third-party
  section — the matrix is the first-party catalogue; the overlay-aware view of installed third-party
  capabilities is 'gsd capability list', not this generated file.

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

* fix(#1435): address code-review — non-vacuous matrix test + generator polish

- capability-matrix-sync.test.cjs: assert the 'security registers a ship:pre gate' precondition
  unconditionally so the extension-point check can never degrade to a vacuous pass on registry drift.
- gen-capability-matrix.cjs: warn (stderr) on an unknown loop point at generation time; rename
  enginesOf -> fmtEngines for consistency with the other fmt* helpers (output unchanged).
- capability-trust-model.md: point the two how-to links at the real files
  (import-a-capability-from-a-url.md, version-a-capability.md) instead of the bare directory.

34bc096ec2 feat(#1451): wire gsd capability install/update/remove/list/disable/enable management CLI (#1457)
* feat(#1451): wire gsd capability install/update/remove/list/disable/enable CLI

ADR-1244 D5/D6: the management command was built as a library (capability-lifecycle.cjs
install/upgrade/remove + capability-ledger.cjs) across Phases 3-5 but never wired to a
user-facing command — gsd-tools.cjs 'capability' only handled state/set. This adds the
six subcommands, dispatching to the existing lifecycle/ledger:

- install <spec> [--integrity] [--scope global|project] [--yes] [--shared-file <rel>]…
- update [<id>|--all] [--scope] [--yes] [--shared-file]  (re-resolves recorded source)
- remove <id> [--purge-data] [--scope]  (first-party rejected)
- list [--json]  (first-party + overlay, both scopes, JSON array)
- disable|enable <id>  (activation-state alias of capability set --off/--on)

Scope→runtimeDir mapping matches capability-loader exactly (global=$GSD_HOME||home,
project=project root; caps at <root>/.gsd/capabilities/<id>, ledger at <root>/.gsd-capabilities.json).
Consent is non-interactive: --yes grants; without it an executable install aborts after
printing the disclosure and writes nothing. Best-effort reconcile before each mutation.

Tests: tests/capability-cli.test.cjs (20 behavioral, real resolver via local specs,
GSD_HOME-sandboxed) — install consent/block/usage matrix, list, update round-trip,
remove round-trip + first-party guard, disable/enable, unknown subcommand.
Docs: docs/reference/gsd-capability-command.md reconciled to the real surface
(ledger paths, --shared-file, consent model, disable mechanism, outdated marked planned);
docs/COMMANDS.md gains the gsd capability entry.

* fix(#1451): resolve adversarial-review findings + root-cause the --raw silent-output bug

Adversarial-review (Codex) fixes:
- capReadStrict passes a malformed strict_known_registries value THROUGH so the trust gate
  fail-closes on it (was silently downgrading to permissive)
- installCapability/upgradeCapability gain an expectedId guard + first-party-id rejection
  (capability-lifecycle.cts): an overlay can't shadow a first-party id, and 'update <id>' can't
  act on a different id if the recorded source was retargeted
- capability update: prints the consent disclosure, exits non-zero on --all partial failure,
  no longer masks the resolved id
- capability remove: ledger-first ordering so an overlay is removable even if it shadows a
  first-party name; first-party guard only fires for ids not in the ledger
- gsd-capability-command.md: disable/enable doc corrected (registry-known ids; overlay toggle
  not yet wired through this path)

Silent-output bug (root cause, not waved off as pre-existing):
- captureStdoutSyncWrites buffered fd-1 output and DISCARDED it on the throw path — any --raw
  command that emitted a result/error envelope then threw (to set a non-zero exit) lost ALL of
  stdout. Now it flushes the captured buffer before re-throwing (exit code preserved).
- cmdCapabilitySet threw via process.exit() (bypassing the capture wrapper entirely); now throws
  ExitError so the wrapper flushes — matches the repo's no-process-exit architecture.
- Regression test: capability disable <unknown> --raw must emit the JSON error envelope on stdout.

Verified: capability suite 165/165, @file/json-errors/phase 183/183, lint clean.

* fix(#1451): address adversarial-review R2 — shared-file confinement, MCP no-clobber, config fail-closed

- confinedSharedFile(): realpath-confine every shared-config write/strip to the scope root (mirrors
  safeRmUnder), so a --shared-file whose parent is a symlink escaping the scope can't write outside it.
- mcpServers shared edits: never overwrite an UNOWNED entry — a name collision with the user's (or
  another capability's) server is skipped, so install/remove can't silently clobber user MCP config
  (hooks already append; the map-keyed mcpServers path was the gap).
- capReadStrict: a PRESENT-but-unparseable .planning/config.json now fails CLOSED (lockdown) instead
  of silently downgrading the strict_known_registries policy to permissive.
- Tests: symlink-escape shared-file writes nothing outside scope; colliding user mcpServers entry
  preserved; unparseable config blocks an external install. capability suite 83/83, lint clean.

* fix(#1451): address code-review — aborted-status robustness + coverage + project-scoped strict doc

- install/update: handle an 'aborted' result independently of the requiresConsent flag so it can never
  fall through to the generic 'blocked: unknown reason' arm (aborted always means consent-needed per
  the lifecycle contract; latent today, hardened for future status additions).
- Clarify capResolveScope comment (project scope === already-resolved cwd) and document that
  strict_known_registries is a PROJECT-scoped policy (read regardless of --scope; no machine-wide
  allowlist) in gsd-capability-command.md.
- Tests: update --all over an empty ledger returns an empty result set (exit 0); a flag value that
  looks like another flag (--integrity --scope) is rejected, not swallowed. CLI suite 33/33, lint clean.

9219af3360 feat(#1433): capability trust gate + upgrade/compat (ADR-1244 Phase 4) (#1449)
ADR-1244 Phase 4 (D5 trust + D6 upgrade/compat). capability-trust.cjs (disclosure/consent, strict_known_registries, engines+compatVersions, reserved namespace) + capability-lifecycle.cjs (install/upgrade/remove/reconcile; ledger-as-commit-point _pending intent; atomic stage-then-swap; surgical marker-isolated shared-edit strip; owner-token lock) + capability-source promote/skipEnginesGate seams + loader pending-skip + config keys. No sandbox re-derived (consent+integrity+reversibility). 6 Codex adversarial rounds + /security-review (no HIGH) + /code-review; gsd-test green both platforms; CI green. Phase 5 (#1434) wires the CLI dispatch.

Closes #1433.
