fix(ci): stop the review agent rejecting its own graph-backed reviews (#2731)
* fix(ci): stop the review agent rejecting its own graph-backed reviews

The context-evidence gate only counted a `context` call when the call
itself passed `file_path` equal to a changed path. The review skill
teaches plain `context({name})`, so 17 of the 26 review-agent run
failures were complete, graph-backed reviews thrown away after full
model spend, with no log line saying which invariant failed.

Prove the evidence from the result instead: `status=found` plus a
`symbol.filePath` inside the repo-scoped changed-path set. Every other
check stays exactly as it was - strict JSON, orchestrator-only turns,
result ordering, duplicate tool-id rejection - and the `repo` argument
still selects the head or the merge-base path set.

Same failure inventory, smaller classes:

- rejection now logs why (in-scope, out-of-scope, sidechain, unresolved
  and off-path counts plus up to three sanitized paths), and the
  envelope error names the message count and first-message shape
- Glob/Grep leave the tool set: they were enabled through `--tools` but
  never allow-listed, so every lane call was denied and burned turns
- both pinned `npm ci` installs retry three times; one registry
  ECONNRESET killed a whole run
- the prompt matches the new contract and asks for the structured body
  even when the analysis is incomplete

* fix(skills): mirror the review-skill tool-set change into the shipped copies

The npm package, Claude plugin, and Cursor integration ship byte-identical
copies of .claude/skills/gitnexus-review, and the drift guard compares them.
Dropping Glob/Grep from the lane frontmatter and the SKILL.md sentence only
landed in the canonical tree.

* fix(ci): stop one junk context result discarding a proven review

Tri-review of this PR found that the previous commit fixed one spurious
rejection and created another. Widening evidence candidacy from "the call
that named a changed path" to "every orchestrator context call" also
widened the *strict-parse* surface: `contextResultProvesChangedPath`
throws rather than returning false, so a single malformed payload
anywhere in the transcript now discarded a review that an earlier call
had already proven. The MCP makes that reachable without any misbehaving
model - `GITNEXUS_MCP_DEFAULT_MAX_TOKENS=12000` truncates any context
payload over ~48 KB mid-JSON and appends a marker - and it also destroyed
docs-only runs that the `no_indexable_changed_symbols` mode exempts.

Reproduced by running the workflow's own embedded script on both trees:
a proving evidence call followed by one truncated exploratory call gave
`failure_code: null` on the base and `invalid_execution_transcript` on
the head; it is `null` again here.

- payload-shape failures are caught and counted (`malformedResults`)
  instead of thrown; transcript-structural invariants (envelope, tool
  shapes, duplicate ids, empty tool_result) still fail closed
- diagnostics gained the reasons they were blind to: errored results,
  results that arrived out of order or via a sidechain, unanswered
  in-scope calls, and malformed payloads. A rejection can no longer
  print an in-scope call with every reason at zero
- a deletion-only PR no longer registers head-scoped candidates that can
  never be satisfied: an empty eligible set is out of scope, not a result
  "outside the changed paths"
- the mandatory-body prompt clause now pairs with a required `complete`
  boolean. An incomplete analysis publishes its partial body labelled
  `incomplete_analysis` instead of passing as an accepted review
- `Agent(a,b,c)` is split into six separate `Agent(x)` rules: the pinned
  base action parses allowedTools with `.flatMap((v) => v.split(","))`
  (parse-sdk-options.ts at 3553f843), which shattered the grouped rule
  into `Agent(ci-correctness-lens`, four bare names, and
  `ci-critic-lens)` before the SDK saw it. Pre-existing and unproven at
  runtime, but the split form is correct under either reading and lets
  the header's dispatch canary actually prove something

* fix(ci): require a line range for context evidence

The tri-review's adversarial lane executed `context({name: 'AGENTS.md'})`
and had the result accepted: the gate checked only that the resolved
filePath was in the changed set, so a bare File node passed for a review
of that file's contents. The trusted prescan already defines an indexable
symbol as one with startLine and endLine, so require the same here.

Pre-existing rather than introduced by this branch, but it is the same
"what counts as proof" surface the rest of this PR tightens.

* fix(ci): close the remaining tri-review findings

Addresses every finding the tri-review left open after 0432214d and
1d9f2d75, across both engines.

Reliability and maintainability (Codex ce, ce-reliability, ce-maintainability):
- both pinned `npm ci` installs now call one shared
  `.github/scripts/npm-ci-retry.sh` instead of two near-identical 12-line
  blocks that differed only in a label
- each attempt runs under `timeout` (default 600s, overridable), so a slow
  registry can no longer crowd the model review out of the job's budget
- the helper distinguishes a timeout kill (124) from an npm rejection in
  its log

Test coverage (ce-testing, Codex swarm P3, ce-security, swarm test-ci):
- the retry helper is now exercised behaviourally with a stub npm: first-try
  success runs once, two failures recover on the third, three failures exit 1
- a non-string `symbol.filePath` is a clean reject, not a type error
- an adversarial resolved path (ESC, newline, `::set-output`, RTL override)
  is proven sanitized before it reaches the job log
- the envelope error's shape string is asserted
- an in-scope call whose result never arrives is counted, not silent
- install flags that keep the runtime inert (`--ignore-scripts`, `--prefix`,
  the lock-bound registry) are asserted against the helper they moved into

Correctness and clarity (risk-architect, ce-standards):
- the prompt now tells the model to prefer the uid form or pass file_path
  when a bare name could resolve into an unchanged file, which was the
  narrower off-path failure mode the gate rewrite left behind
- `contextResultProvesChangedPath` -> `contextResultProvesEligiblePath`,
  matching the set-membership contract its sibling was renamed for
- the transcript fixture's default no longer carries a `file_path` the gate
  ignores, which implied the opposite of the contract
- SKILL.md says "file reads" rather than naming a CLI-specific tool, per
  the CLI-neutrality rule in AGENTS.md; mirrored to all three shipped copies
- the interactive-swarm README notes the CI lanes are narrower

Publisher (ce-reliability residual, pre-existing):
- the publish job no longer gates the whole job on authorization, so a
  request rejected at normalization no longer strands the "review in
  progress" marker on the PR forever. Publication stays authorization-gated
  at the step; only the marker cleanup is unconditional.

* fix(ci): ship the install helper executable

The extracted helper was committed 100644, so the workflow's direct
invocation would have failed on the runner with permission denied - a
break introduced by the extraction itself, invisible to every existing
assertion. Set the mode and pin it with a test.

fix(lang-kotlin): support fun interface extraction via tree-sitter-kotlin re-vendor (#2271)
* fix(lang-kotlin): support `fun interface` extraction via tree-sitter-kotlin re-vendor

Vendored tree-sitter-kotlin@0.3.8 (fwcd) parsed `fun interface Foo` as an
ERROR node and dropped the declaration plus its abstract method, so functional
(SAM) interfaces were never extracted. The fix landed upstream in
fwcd/tree-sitter-kotlin#169 (closes #87), merged to main 2025-04-25, but is not
in any npm release (latest tag 0.3.8; main is the unreleased 0.4.0).

Re-vendor the grammar from the unreleased fwcd main commit c8ac3d26:
- refresh src/{parser.c,scanner.c,node-types.json,tree_sitter/*.h} and
  bindings/node/index.js; bump the vendor version 0.3.8 -> 0.4.0; record the
  pinned SHA + rationale in _vendoredBy and the vendor README.
- switch the prebuild workflow's kotlin registry kind 'npm' -> 'vendored' (the
  fix is unreleased on npm, so prebuilds must build from the vendored C source,
  like swift/dart/proto).
- add a hold to .github/vendored-grammars.json so the weekly auto-update
  monitor does not strict-inequality-revert the pin to the broken npm 0.3.8
  (isNewer compares 0.3.8 != 0.4.0).
- add 3 regression tests + a fixture asserting fun interfaces extract as
  Interface nodes with their abstract methods, and that plain-interface
  heritage still resolves.

Existing KOTLIN_QUERIES need no change: the new grammar models `fun interface`
as a class_declaration with an "interface" keyword child (plus an extra "fun"
modifier child), which the existing interface rule already matches. Full Kotlin
suite green against the new grammar (300 unit/cfg/resolver + 233 integration).

NOTE: prebuilds/ are intentionally not in this commit. The version bump
auto-triggers .github/workflows/build-tree-sitter-prebuilds.yml, which
regenerates all 6 platform binaries from the vendored source in a separate PR.
Until that lands, CI loads the committed 0.3.8 prebuild, so the new kotlin
tests are red and the grammar change is inert at runtime. Merge the prebuild PR
first or together.

* test(ci): count kotlin's vendored hold as a 0.25-readiness blocker

The kotlin `hold` added in the previous commit makes the tree-sitter
upgrade-readiness report count it as a blocker — the report treats every
held vendored grammar as frozen below a runtime upgrade (same as the
intentionally-pinned tree-sitter-cpp and the ABI-held tree-sitter-c),
"in-range ABI or not". So the report's blocker count goes 2 -> 3.

Update the hardcoded count in
test_issue_update_summary_regex_matches_current_report (and the
_render_report docstring) accordingly — exactly as that test instructs:
"if a grammar is added/removed or a pin/hold changes, update the expected
counts". kotlin's ABI (14) is in range; the hold is what flags it, with the
reason recorded in .github/vendored-grammars.json.

* test(ci): refresh kotlin baselines for the grammar bump

Two committed baselines pinned the pre-bump kotlin state and broke when the
grammar was re-vendored (0.3.8 -> 0.4.0):

- cli-commands.test.ts pinned the vendored kotlin package version at 0.3.8 ->
  update to 0.4.0.
- bench/scope-capture/baselines.json: the new kotlin-fun-interface fixture joins
  the lang-resolution/kotlin-* corpus AND the new grammar parses `fun interface`
  as a class_declaration (not an ERROR node), so the capture fingerprint drifts.
  Rebaselined to the NEW grammar's fingerprint (verified by building the vendored
  parser.c against tree-sitter@0.21.1 and running measure.mjs --check); scaling
  ~0.83 (linear).

Like the fun-interface integration tests, the scope-capture --check passes only
once the regenerated prebuilds land; until then CI loads the committed 0.3.8
binary, so it stays red.

* ci(prebuilds): rebuild + commit grammar prebuilds into the PR on vendored-source change

build-tree-sitter-prebuilds.yml previously rebuilt a grammar's native prebuilds
only when its package.json VERSION bumped, and delivered them via a separate bot
PR. Now any change to the vendored grammar source re-cuts the prebuilds and they
ride into the same PR.

- Trigger on any build-affecting change under gitnexus/vendor/tree-sitter-*/**
  (parser.c, grammar.js, binding.gyp, scanner, bindings), not just version bumps.
  The prebuilds/ subtree is negated in the paths filter AND excluded from the
  guard's source diff, so the bot's own prebuild commit can never retrigger the
  workflow (no build -> commit -> build loop).
- The guard builds a grammar when its recorded version changed OR its vendored
  source changed vs the PR base.
- Same-repo PRs get the rebuilt prebuilds committed straight onto their own head
  branch (included in the SAME PR) via a non-force push that only adds a commit
  on top of head. Manual dispatch still opens a fresh chore/ PR; fork PRs stay
  artifacts-only (a bot cannot push into a fork branch).

* ci(prebuilds): deliver rebuilt prebuilds to fork PRs via a trusted workflow_run stage

A fork PR's producer run has a read-only token and no secrets, so it can build and
validate the prebuilds but can't commit them. Add the safe two-stage handoff that
mirrors the pr-autofix producer/publish split.

- build-tree-sitter-prebuilds.yml (untrusted producer): on a fork PR, upload a
  pr-meta artifact (schema, pr_number, head_sha, head_ref, head_repo, base_repo)
  alongside the prebuild artifacts. Values flow through env + jq, never
  interpolated into a shell.
- commit-fork-prebuilds.yml (trusted, workflow_run): downloads ONLY the artifacts
  (never executes fork code — it checks out the pinned HEAD SHA solely to add
  files), allowlist-validates every metadata field, cross-checks identity against
  the workflow_run authority (head_sha / head_repo / pr_number, via
  commits/{sha}/pulls for forks), then pushes the prebuilds onto the fork head
  branch with --force-with-lease + http.extraheader auth. No PAT: this works when
  the contributor left "Allow edits by maintainers" on; on push failure it posts a
  sticky comment telling them to enable it or commit the downloaded artifacts.

zizmor: allowlist commit-fork-prebuilds.yml's workflow_run dangerous-trigger with
the documented mitigation, matching the existing ci-report / pr-autofix entries.

* chore(vendor): rebuild tree-sitter-kotlin prebuilds for the re-vendored fun-interface grammar

The fun-interface re-vendor changed vendor/tree-sitter-kotlin source but left main's
old (0.3.8) prebuilds in place, so all 6 platform binaries were stale relative to the
new parser. Replace them with the freshly cross-built + ABI-validated binaries from
build-tree-sitter-prebuilds run 28010841458 — each .node was require()-loaded and
parsed a snippet on its target platform-arch before upload.

This is the manual equivalent of the commit-fork-prebuilds.yml delivery, which can't
run for this fork PR until it lands on main.

* fix(lang-kotlin): read extension-function receiverType from the re-vendored grammar's `receiver` field

The fun-interface re-vendor changed the kotlin AST: an extension function's
receiver is now a `receiver_type` exposed via a named `receiver` field, where the
old grammar emitted a bare user_type before the name. extractReceiverType only
matched the old shape, so receiverType came back null
(method-extraction.test.ts > Kotlin MethodExtractor > extracts receiverType).
Prefer the `receiver` field (unwrapping it), and keep the old child-scan — now
also recognizing `receiver_type` — as a fallback.

ci: fail tree-sitter summary parse drift (#2246)
* ci: fail tree-sitter summary parse drift

* docs(ci): cross-reference readiness regexes to their test mirror

The two report.match() literals in the upsert-issue github-script step are
duplicated as _ISSUE_READY_RE / _ISSUE_BLOCKER_RE in
test_check_tree_sitter_upgrade_readiness.py, and only the Python copy is
asserted against the rendered report. Since a stale regex now throws via
requireMatch (instead of the old silent '?' fallback), add a reciprocal
keep-in-sync note at the workflow site so a future prose edit can't desync
the JS literal from the asserted mirror undetected.

* fix(ci): route read-phase network failures to fetch_failed, not a crash

npm_view_json and fetch_text caught only (URLError, HTTPError[, JSONDecodeError]).
urllib wraps connect-phase OSErrors into URLError, but a failure during
resp.read() AFTER urlopen returns (ConnectionResetError, ssl.SSLError,
socket.timeout, http.client.IncompleteRead) is not a URLError subclass — it
escaped the helper, crashed main(), and left stdout empty. main() is unguarded
(the only top-level except wraps just stdout.reconfigure), and the report print
is its last statement, so an empty report then makes the workflow's requireMatch
throw on a non-drift scheduled run.

Broaden both except tuples with OSError + http.client.IncompleteRead so a
transient mid-body network blip yields None, routing the grammar to the existing
fetch_failed blocker bucket (a complete report) — preserving the fail-loud intent
for real drift while removing the crash-to-empty-stdout path. JSONDecodeError
stays explicit (it is a ValueError, not an OSError). Adds read-phase regression
tests that fail on the old narrow tuple.

* test(ci): document the regex-contract assertion counts

test_issue_update_summary_regex_matches_current_report asserts hardcoded
capture groups ("9","10") and "2" with no explanation. Document the
derivation from _render_report()'s mock corpus — 9 of 10 npm grammars Ready
(tree-sitter-cpp is the intentional pin), 2 blockers (pinned tree-sitter-cpp +
held vendored tree-sitter-c) — so a future grammar or pin change is an obvious
two-step update (mock + counts) rather than a mystery failure. Assertions
unchanged; comment only.

* ci: name _Resp method receivers 'self' to clear py/not-named-self

The _Resp stub inside _patch_urlopen named its method receivers
`self_inner`, which CodeQL flags as py/not-named-self (PEP 8) — three
alerts on this PR's merge ref (lines 230/233/236). _patch_urlopen is a
@staticmethod, so there is no outer `self` to collide with; rename the
receivers to the conventional `self`. Pure rename, no behavior change.

All 25 tests in test_check_tree_sitter_upgrade_readiness still pass.

* chore(ci): add shared vendored-grammars manifest; monitor reads it

.github/vendored-grammars.json is the single source of truth for the vendored
tree-sitter grammars (c/swift/kotlin/dart/proto): name, upstream coords, and
policy holds. update-vendored-grammars.mjs now builds its GRAMMARS map from the
manifest (behavior-preserving — same exported shape). Adds manifest-agreement
tests so the loader can't silently skew from the file.

* fix(ci): classify vendored grammars from manifest, drop bare "?" (#858)

The readiness report decided "is this vendored?" via is_vendored_pin (a file:
package.json spec) — but the 5 vendored grammars aren't in package.json, so they
were misrouted through the npm path and rendered bare "?" for ABI (read from an
empty node_modules), plus a spurious "? (fetch failed)" for github-only proto.

Now vendored grammars are classified by membership in the shared manifest and
their ABI is read from gitnexus/vendor/<name>/src/parser.c (always in a
checkout). github-only vendored grammars skip the npm peer-dep fetch; the
tree-sitter-c hold is surfaced from the manifest (held, not plain "Ready"); and
every remaining unintrospectable value renders a labeled token, never a bare
"?". --assert-current now covers the vendored grammars too instead of skipping
them. Adds a stdlib unittest suite incl. a manifest⇄vendor-dir consistency
guard.

* docs(ci): document the shared vendored-grammars manifest

Both tree-sitter workflow headers now point at .github/vendored-grammars.json as
the shared source of truth; the readiness workflow gains a PR-path trigger on the
manifest + test, and runs the readiness unit tests on validation events.
CONTRIBUTING.md documents the manifest contract under CI automation contracts.

* fix(review): apply autofix feedback

- Guard manifest reads in both scripts with a clear error (was an opaque
  module-import traceback that crashed the script and test collection).
- Never render a bare "?": relabel the npm-path ABI/version/peer sentinels and
  the vendored upstream-ABI miss to labeled tokens; the report is now ?-free
  regardless of node_modules/network, and the test is hermetic.
- Add a VENDORED_NAMES ⊆ GRAMMARS guard + manifest-missing error test.
- Drop now-dead is_vendored_pin/is_vendored/_(vendored)_.
- Compose held + out-of-range vendored blocker reasons instead of overwriting.
- Reword the shared-manifest docs to not over-claim shared upstream coords.

* fix(ci): apply root prettier formatting to mjs + ts test

The quality/format gate runs root `prettier --check .` (printWidth 100, the
gitnexus-local config differs and falsely passed locally).

* test(ci): make both tree-sitter scripts testable offline

The scripts hit live npm/GitHub, which makes the report run flaky and the
monitor's detect/apply logic untestable. Add hermetic seams:

- readiness: --offline flag (+ GITNEXUS_TS_READINESS_OFFLINE env) no-ops the npm
  registry + upstream fetches; the report renders deterministically (vendored
  ABIs from the repo, npm columns marked 'offline', no bare '?'). 3 tests assert
  an offline run touches ZERO network (urlopen patched to raise).
- monitor: detect() and apply() accept injected deps (vendoredVersion/
  resolveUpstream/fetchSource/readAbi) so the newer/ABI/hold gating runs offline
  with fixtures; apply gains --dry-run (validates but writes nothing). 6 tests
  cover newer/same-version/held-c/ABI-15/applicable + a no-mutation dry-run.

* fix(review): keep --assert-current hermetic + harden the no-bare-? invariant

Tri-review findings (PR #2187):
- P2 REGRESSION: --assert-current (documented 'hermetic and offline', run in CI
  without --offline) routed the 5 vendored grammars through vendored_drift_summary,
  which fetches upstream parser.c + commit sha — 10 discarded network calls per run.
  Fix: read the vendored ABI locally via a new vendored_abi_from_repo() helper (also
  used by vendored_drift_summary). Now verifiably network-free.
- Unify the upstream-ABI miss sentinel: prose said 'n/a (generated at build)' while
  the matrix said 'n/a' — and 'generated at build' is a wrong cause (swift HAS a
  committed parser.c). Both now render neutral 'n/a'.
- Fix the stale assert_current docstring claiming swift is prebuilt-only/no parser.c.
- Guard the last latent bare-? path (vendor package.json missing 'version').

Tests: AssertCurrent (network-free guard + out-of-range via the new injection
point), malformed-JSON manifest, detect() error-path, explicit npm/github
undefined assertions. 17 Python + 15 vitest, all hermetic.

* fix(review): use a single unittest import style (CodeQL 753)

CodeQL py/import-and-import-from flagged `import unittest` + `from unittest
import mock`. Collapse to `from unittest import TestCase, main, mock`.

* fix(review): explicit raise in _matrix_row (CodeQL 754)

CodeQL py/mixed-returns flagged the implicit fall-through after self.fail()
(which it doesn't model as NoReturn). End with an explicit raise AssertionError.

* test(review): replace non-null assertions with a must() guard

@typescript-eslint/no-non-null-assertion flagged 4 `!` operators. Add a
narrowing must<T>(value, message) helper (throws on undefined) and a named
baseResolveUpstream, removing every non-null assertion.

* fix(review): unguessable heredoc delimiter for the report output

The report embeds the manifest `hold` field (fork-PR-editable); a fixed
DRIFT_EOF delimiter in a hold value could close the $GITHUB_OUTPUT heredoc
early and inject output keys. Use DRIFT_EOF_$(openssl rand -hex 16) — a value
the report cannot contain. (Randomized delimiter over base64: keeps REPORT raw
markdown, no consumer-side decode.)

* fix(review): scope issues:write to scheduled runs (two-job split)

GitHub Actions has no step-level permissions, so the only way to keep PR runs
(incl. forks) from receiving `issues: write` is to split the job. A `report`
job (contents:read, all events) renders the report + the PR `:⚠️:` and
exposes report/exit_code as job outputs; a schedule-only `upsert-issue` job
(needs: report, issues:write, no checkout) consumes them for the issue upsert +
close. The 'Check upgrade readiness' check name is preserved.

* fix(review): launder npm-version '?' in disposition prose

The disposition bucket prose interpolated r['npm_version'] raw, so a successful
200 npm /latest response lacking a 'version' key would render a bare '?' (the
matrix cell already laundered it). Add npm_version_label ('unknown' for '?') and
use it in all five bucket renderers. Test a version-less npm response.

* refactor(review): load_vendored_manifest returns only the consumed 'hold'

The readiness script reads only the grammar names + 'hold'; the 'key' and
'upstream' fields were phantom data (upstream-drift coords live in the script's
own GRAMMARS map). Narrow the return to {hold}.

* fix(review): unify detect()/apply() 'newer' check for github grammars

detect() compared the bare sha7 while apply() compared up.version (the full
<base>-g<sha7> provenance string apply() also writes). After the bot re-vendored
a github grammar once, detect() reported a perpetual false 'update available'
while apply() correctly saw 'already current' — a noisy job summary + wasted
--apply subprocess (the PR-exists guard absorbed it before any duplicate PR).
Extract a shared isNewer(up, have) helper used by both. Tests cover equal-
provenance (false), first-vendoring plain-version (true, not suppressed), and
sha-advanced (true). Coupled with U12 (the detect⇄apply agreement assertion
lives there once apply()'s not-newer path returns instead of process.exit).

* test(review): cover main()'s out-of-range + prebuilt-only vendored ABI branches

main()'s vendored-ABI classification reads through vendored_abi_from_repo (the
local-read seam --assert-current uses), so patching it drives the
'Vendored (ABI out of range)' blocker branch and the prebuilt-only (vendored_abi
None → 'prebuilt' cell, not '?') branch — neither reachable today since all 5
vendor dirs ship parser.c at ABI 14.

* test(review): monitor-side manifest⇄vendor-dir consistency guard

Mirror the Python consistency guard on the monitor side — the monitor consumes
the same manifest and is the side that WRITES files from manifest `name`, so
manifest/vendor-dir drift must fail CI here too.

* fix(review): validate grammar names at manifest load (path-traversal guard)

The manifest `name` is joined into gitnexus/vendor/<name> paths in both scripts
(and apply() WRITES there), so reject any name not matching tree-sitter-[a-z0-9-]+
at the single load chokepoint — defense-in-depth even though the live trust
boundary already prevents exploitation. loadManifestGrammars gains an injectable
`raw` arg + export for testing; tests reject a '../etc' name in both scripts.

* refactor(review): apply() throws ApplyExit; CLI maps to exit codes

apply()'s 4 process.exit calls killed the vitest worker, blocking in-process
tests of its error branches. Replace them with a thrown ApplyExit{code}; the
not-newer (already-current) path returns `have` instead of exit(0). The isMain
CLI block try/catches and maps ApplyExit.code → process.exit, so the monitor's
subprocess contract (exit 0/2/3) is byte-identical (verified via subprocess
smoke). Tests cover unknown-key=2, held=3, ABI-reject=3, and not-newer (returns
current, no throw, no write).

* refactor(review): extract vendored render helper; trim docstrings (<1000 lines)

Extract the 'Vendored parsers' prose render into _render_vendored_section() so
main() coordinates named phases rather than inlining a ~450-line monolith, and
condense the most verbose docstrings/comments. The script drops from 1092 to 999
lines (under the 1000 bar the maintainability review flagged). Behavior-preserving:
the deterministic --offline render is byte-identical before/after (verified
in-place), --assert-current still passes, and the full unit suite is green.

* fix(review): row-diff regex captures only the Status cell

The change-detection regex captured the whole row tail as group 2, so any
non-status cell drift (e.g. an upstream-ABI bump) emitted a false-positive
'change' line. Capture only the Status cell ([^|]+? before the final |$).
The workflow parseRows regex and the Python _ROW_DIFF_RE stay byte-identical;
the stability test now asserts group 2 is the status string (e.g. c →
'Vendored — held') and contains no pipe.

* fix(ci): hoist intro string out of the list literal (CodeQL 755)

The U13 extraction moved the 'Vendored parsers' intro paragraph (implicitly
concatenated string literals) INTO a list literal, tripping CodeQL
py/implicit-string-concatenation-in-list (reads as a possibly-missing comma
between elements). Hoist it into a parenthesized `intro` variable. Render is
byte-identical.

feat(install): toolchain-free tree-sitter via vendored prebuilds (#2113)
* feat(install): toolchain-free tree-sitter via vendored GitNexus-built prebuilds

Eliminate the C/C++-toolchain requirement at install for the at-risk grammars
(dart, proto, kotlin) by generating + vendoring native prebuilds, mirroring the
existing vendored tree-sitter-swift. The 10 grammars that already ship 6 upstream
prebuilds stay npm dependencies (toolchain-free AND dependency-review-tracked).

- .github/workflows/build-tree-sitter-prebuilds.yml: a registry-parameterized
  workflow that builds {dart,proto,kotlin} x {linux,darwin,win32}-{x64,arm64}
  prebuilds natively, validates each loads + parses on its arch, and opens a PR
  vendoring them. A `guard` job gates the heavy matrix to run ONLY on dispatch
  or a real grammar-version change — ordinary code PRs cost zero matrix minutes.
- dart/proto: prefer a committed prebuild; fall back to today's source build
  when none matches (no behavior change until prebuilds are vendored).
- kotlin: vendor it (Swift parity) instead of compiling the third-party
  optionalDependency from source at the user's install — supersedes #2110's
  optionalDependency mechanism. The ~23 MB parser.c is NOT vendored (the
  workflow builds from the published package); only node-types + bindings +
  prebuilds are. Removed from optionalDependencies; lock regenerated; probe,
  parser-loader note, README/.devcontainer docs, and the #2110 tests updated.

DO NOT MERGE until vendor/tree-sitter-kotlin/prebuilds/ is populated by the
build-tree-sitter-prebuilds workflow: until then Kotlin is unavailable (vendored
with no source-build fallback). dart/proto remain fully functional throughout.

* test(install): guard 6/6 N-API prebuild coverage for every grammar

Regression guard so a toolchain-less install can never silently lose a tree-sitter
language on a supported platform-arch:

- Vendored grammars (vendor/tree-sitter-*): every one MUST ship a loadable N-API
  prebuild for all 6 tuples {linux,darwin,win32}-{x64,arm64}. Asserts the
  napi_register_module_v1 entry symbol in each .node (cross-platform, no need to
  run the binary). Currently RED for dart/proto/kotlin until the
  build-tree-sitter-prebuilds workflow populates their prebuilds/ — this is the
  must-fill-before-merge gate (swift already passes 6/6).
- npm-dependency grammars: asserts upstream ships 6/6 N-API too, catching a
  future platform drop. tree-sitter-c is allow-listed at 4/6 (missing
  linux-arm64/win32-arm64) pending #2116; the guard also fails if that gap is
  silently closed (prompting allow-list removal).

* feat(install): vendor tree-sitter-c at 0.21.4 with GitNexus-built prebuilds (#2116)

tree-sitter-c is the one grammar dependency upstream ships incomplete prebuilds
for (4/6 — no linux-arm64/win32-arm64), AND it is a REQUIRED grammar: its own
`install` (node-gyp-build) compiles from source when no prebuild matches and
exits non-zero, so on a toolchain-less ARM host `npm install gitnexus` HARD-FAILS
at the c step — during npm's dependency phase, before any GitNexus postinstall
runs (so a postinstall "supplement" can't help).

Fix: vendor c prebuild-only at the pinned 0.21.4 (Kotlin pattern), with all six
prebuilds GitNexus-cross-built, and drop it from `dependencies`:
- vendor/tree-sitter-c/ (bindings + node-types + manifest + prebuilds); build
  probe scripts/build-tree-sitter-c.cjs; added to the build workflow registry
  (kind 'npm' — built from c@0.21.4 source).
- materialize-vendor-grammars.cjs: c is REQUIRED, so it is always materialized,
  even under GITNEXUS_SKIP_OPTIONAL_GRAMMARS (it needs no toolchain).
- Removed from package.json dependencies + lockfile (nothing else needs npm c —
  tree-sitter-cpp's dep on c is dev-only and not installed). Preserves the #1242
  ABI pin: vendoring 0.21.4 keeps the good ABI while closing the ARM gap.
- parser-loader note + the prebuild-coverage guard + a cli-commands assertion
  updated; c moves from the npm-gap allow-list into the vendored 6/6 cohort.

Verified: tsc clean, 31 unit tests pass, c loads/parses; the guard is RED for
c/dart/proto/kotlin until the workflow populates prebuilds (the must-fill gate).
Closes the operational risk in #2116.

* fix(ci): source-build fallback for vendored c/kotlin so CI is healthy pre-prebuilds

The vendored prebuild-only grammars (c, kotlin) had empty prebuilds/ until the
build-tree-sitter-prebuilds workflow runs, so they could not load in CI — and
C is hard-required by cross-platform tests (tree-sitter-languages/parsing on
ubuntu+macos+windows), which I cannot pre-build for macos/windows locally. The
robust fix is a source-build fallback that works on every CI runner (all have a
toolchain), mirroring dart/proto:

- Vendor the grammar source (binding.gyp + src/) for c and kotlin; their build
  scripts now PREFER a committed prebuild (toolchain-free) and fall back to
  `node-gyp rebuild` from the vendored source when no prebuild matches. Verified
  both compile against the hoisted node-addon-api@^8 and the runtime loads.
- prebuild-coverage guard is now bootstrap-tolerant: a grammar that vendors its
  source (binding.gyp) may have an incomplete prebuild set (the workflow fills
  it); a prebuild-only grammar (swift) still must ship all six. Any present
  prebuild must still be N-API. Guard goes green; it re-tightens per-grammar as
  the workflow populates prebuilds.
- actionlint: silence a false-positive SC2016 (JS template literals inside the
  single-quoted `node -e` validate block).

Note: kotlin's generated parser.c is large (~23 MB on disk; compresses heavily
in git). Once the workflow populates all six kotlin prebuilds, the source serves
only as the fallback and could be slimmed if desired.

* fix(docker): re-materialize+rebuild vendored grammars after npm prune

`npm prune --omit=dev` in the gitnexus CLI image drops anything not in
package.json's dependency tree — including the VENDORED tree-sitter grammars
(materialized by postinstall, not declared deps) and their built bindings. The
`serve` image analyzes/parses repos at runtime, so re-run the grammar postinstall
after the prune (in the toolchain-equipped builder) to restore them. Load-bearing
for tree-sitter-c, a core REQUIRED grammar now vendored (#2116): as a former
dependency it survived prune; vendored, it would not. Also restores
swift/dart/proto/kotlin, which were silently pruned from the image before.

* feat(grammars): unify tree-sitter-swift with the vendored-source build pipeline

Swift was the last grammar handled differently — it shipped only upstream
prebuilds, while c/dart/proto/kotlin vendor their grammar source and use a
prefer-prebuild -> source-build-fallback activation script. Vendor swift's
source so all five are handled identically (one uniform build path).

- vendor/tree-sitter-swift: add binding.gyp (win-hardened), bindings/node/
  binding.cc, src/parser.c (ABI-14 default, ~18 MB), src/scanner.c, and
  src/tree_sitter/ headers. The 6/6 prebuilds are retained. The legacy
  parser_abi13.c alternate is intentionally not vendored.
- build-tree-sitter-swift.cjs: rewrite the prebuild probe into the dart-style
  prefer-prebuild then source-build fallback (keeps the GITNEXUS_SKIP gate and
  the never-exit-non-zero postinstall invariant).
- build-tree-sitter-prebuilds.yml: register swift (kind 'vendored'); add its
  package.json to the version-gated pull_request paths and a validate snippet.
- prebuild-coverage guard auto-moves swift into the source-fallback cohort
  (binding.gyp now present); refresh the stale "swift is prebuild-only" comments.
- tests: add build-tree-sitter-swift-probe.test.ts; fix the pre-existing
  build-tree-sitter-kotlin-probe.test.ts breakage (it still asserted the old
  probe strings after kotlin's dart-style conversion); assert swift's vendored
  source in cli-commands.test.ts.
- docs: README / .devcontainer / kotlin vendor README — swift's prebuilds are
  now GitNexus-cross-built from vendored source like the rest, not upstream-only.

Verified: swift source-builds against node-addon-api@8 -> N-API binary -> loads
against the pinned tree-sitter@0.21.1 (ABI 14) -> parses cleanly.

* feat(publish): gate a lean prebuilds-only npm tarball behind a coverage guard

Vendoring grammar source (parser.c) alongside the prebuilds means the npm
tarball now carries ~50 MB of generated source it almost never compiles (every
supported platform-arch has a prebuild). Prepare to drop it from the published
package once all prebuilds exist — safely.

- .npmignore: add a GATED, commented-out "lean publish" block that excludes the
  source-build inputs (parser.c/scanner.c/tree_sitter/binding.gyp/binding.cc) but
  keeps prebuilds/ + the runtime files. Uncommenting ships prebuilds-only.
- scripts/assert-publish-grammar-coverage.cjs: a prepack guard that refuses to
  pack/publish if the source exclusion is active while any vendored grammar still
  lacks 6/6 prebuilds (which would ship a grammar with no loadable binding). Wired
  into `prepack` (runs on npm pack + publish, incl. the publish.yml dry-run) and
  exposed as `npm run assert-publish-coverage`.
- test: pure-core decision cases + a real-repo publish-safety check that fails CI
  if .npmignore is activated prematurely.

Net: the prebuilds already publish today (files: ["vendor"]); this makes the
future switch to a prebuilds-only tarball a one-line uncomment that can't ship a
dead grammar. The guard currently reports "source + prebuilds" (only swift has
6/6 prebuilds so far) and passes.

* refactor(grammars): consolidate the 5 build-tree-sitter-*.cjs into one

The per-grammar activation scripts (c/dart/proto/swift/kotlin) were ~95%
identical — same prefer-prebuild → source-build → never-fail flow, differing only
in name, target_name, required-vs-optional, and the display label in warnings.

- scripts/build-tree-sitter-grammars.cjs: one registry-driven script. Bare call
  builds all (postinstall); `... <name>` builds only the named grammars (so the
  probe test can isolate one). c is `required: true` (ignores the opt-out gate);
  the rest honor GITNEXUS_SKIP_OPTIONAL_GRAMMARS. Per-grammar try/catch + a final
  process.exit(0) preserve the postinstall never-exit-non-zero invariant.
- package.json: postinstall is now `materialize && build-tree-sitter-grammars.cjs`
  (was five chained `build-tree-sitter-<name>.cjs` calls).
- tests: replace the two near-identical *-probe.test.ts files with one
  parameterized build-tree-sitter-grammars-probe.test.ts that also covers the
  required-vs-optional opt-out split and an unknown-grammar arg.
- update cli-commands.test.ts postinstall assertions + the vendor c/kotlin/swift
  README + swift provenance to reference the consolidated script.

Behavior is preserved (warnings normalized to one consistent format). Removes 5
scripts + 1 test file; adds 1 script + 1 test.

* fix(ingestion): lazy-load tree-sitter-c to prevent module-load crash

tree-sitter-c is now vendored prebuild-only (#2116) with 0/6 committed
prebuilds, so on a toolchain-less or `--ignore-scripts` install C has no native
binding. Three modules loaded it via a hard top-level `import C from
'tree-sitter-c'`, which throws ERR_MODULE_NOT_FOUND at module-load — crashing
`analyze` before parser-loader's optional/severity:error degradation can run.
This is the #2091/#2093 bug class (previously fixed for swift/dart/kotlin); C was
left static because it used to be an always-present npm dependency.

- languages/c/query.ts: load via the lazy guarded getLanguageGrammar(C), mirroring
  swift/query.ts; the main-thread isLanguageAvailable filter ensures the getters
  are reached only when C is present.
- workers/parse-worker.ts: guarded `_require('tree-sitter-c')` + conditional
  languageMap spread, like swift/dart/kotlin.
- group/extractors/include-extractor.ts: guarded `_require`; getLanguageForFile
  returns null for .c/.h when absent, so C include-extraction degrades to a no-op
  (C++ unaffected).
- extend the registry-import-closure regression test (#2091/#2093) to assert C
  also loads lazily at registry static-import time.

* fix(ci): repin attest-build-provenance to the real v2.4.0 SHA

The workflow pinned actions/attest-build-provenance@bd77c077… commented
`# v2.4.0`, but v2.4.0 is e8998f94… (verified via the GitHub API); bd77c077…
is an untagged mid-stream commit, so the SLSA-attestation step ran unvetted
action code and the comment misrepresented what runs. Repin to the real
v2.4.0 commit and drop the `# PLACEHOLDER-PIN` markers on both this line and
the setup-python pin (a26af69b… is already the correct v5.6.0 — only its
comment was stale). Update the header NOTE accordingly.

* fix(ci): skip the prebuild-PR aggregate when release App secrets are absent

The aggregate job mints a GitHub App token as its first step; with
RELEASE_APP_ID/RELEASE_APP_PRIVATE_KEY unset it hard-failed AFTER a full
(up-to-6-runner) native build. Since the `secrets` context isn't available in
a job-level `if:`, the guard job now computes a `release_app` boolean output
(a step can read secrets) and emits an actionable `::notice::`; aggregate
gates on it and skips cleanly, while the build job's artifacts still upload
(run with open_pr=false for artifacts-only).

* chore(ci): drop package-lock.json from the prebuild paths filter; widen build timeout

`gitnexus/package-lock.json` changes on nearly every dependency PR, so it
fired the prebuild workflow's guard job on unrelated churn (the matrix stayed
correctly skipped — `gitnexus/package.json` already covers the transition-window
pin, so removing the lock only drops guard noise). Also bump the native build
job timeout 30 -> 45 min for headroom compiling the 23 MB kotlin / 18 MB swift
parser.c, especially under arm emulation.

* fix(ci): event-gate the aggregate open-PR condition explicitly

`inputs.open_pr` is null on pull_request events, and the prior
`inputs.open_pr != false` leg relied on GHA's direction-ambiguous null
coercion (Codex F4) to decide whether to open the prebuild PR. Gate
explicitly on the event: a non-fork pull_request that bumped a grammar
version opens the prebuild PR (the documented flow), and `open_pr` is only
consulted on workflow_dispatch — so a manual run with open_pr=false stays
artifacts-only and no event's behavior rests on coercion.

* fix(publish): validate the effective npm-pack contents in the coverage guard

The publish guard inferred "is source shipped?" from a single .npmignore toggle
line, which a partial/out-of-order edit could defeat (exclude binding.gyp but
leave parser.c → unbuildable yet "source-shipping"). It now inspects the
EFFECTIVE tarball via `npm pack --dry-run --ignore-scripts --json` (the
--ignore-scripts avoids re-entering this guard through prepack): a grammar
"ships source" only when EVERY on-disk source-build input (binding.gyp +
binding.cc + parser.c + scanner.c when present + a tree_sitter header) is
actually in the packed file list.

This also surfaced that the gated lean-publish .npmignore block was inert:
package.json's `files: ["vendor"]` allow-list overrides .npmignore for the
vendored subtree, so those exclusion lines never dropped anything. Replace the
dead toggle with documentation of the real mechanism (narrow the `files` field)
and note the guard enforces safety on the effective pack regardless of how the
slim is done.

* test(prebuild): hard-gate declared-fully-prebuilt grammars on 6/6 coverage

The strict 6/6 prebuild assertion was dormant whenever a grammar vendors source
(binding.gyp) — which is every grammar — so a dropped prebuild passed CI
silently. Add a FULLY_PREBUILT allowlist of grammars GitNexus has committed 6/6
for (today: swift); those must keep all six even with a source fallback, so
losing one now fails CI. Grammars graduate into the set as the
build-tree-sitter-prebuilds workflow lands their binaries. (The static-import
degradation smoke is covered by the registry-import-closure regression test
extended in the C lazy-load commit.)

* chore(deps): promote node-gyp-build/node-addon-api to regular dependencies

Every vendored grammar's index.js does `require("node-gyp-build")` at runtime
to load even a prebuilt .node, so node-gyp-build is runtime-load-critical (and
node-addon-api is needed for the source-build fallback). They were
optionalDependencies, surviving `--omit=optional` only via the required
tree-sitter's transitive edge — correct today but fragile. Promote both to
regular dependencies so the contract is explicit (optionalDependencies is now
empty and removed). Lock the contract with a cli-commands assertion.

* chore(vendor): add Windows cflags parity block to tree-sitter-c/binding.gyp

c's binding.gyp used an unconditional `cflags_c: ["-std=c11"]`, while
kotlin/swift gate MSVC flags behind an `OS=='win'` condition (/std:c11 /utf-8).
Inert today (no non-ASCII bytes in c's parser.c, and node-gyp ignores cflags_c
on MSVC anyway), but align the three so a future source-build fallback on
Windows behaves consistently.

* docs(agents): correct stale optional-grammar / postinstall notes

AGENTS.md still said postinstall "patches tree-sitter-swift, builds
tree-sitter-proto" and that only kotlin/swift are "optional". Update to the
vendored-uniform model: postinstall materializes the vendored grammars and
prefers a committed prebuild (source-build only when none matches); c is
required while dart/proto/swift/kotlin are optional + skippable via
GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1, with non-fatal warnings only on a
toolchain-less host with no matching prebuild.

* fix(install): preserve the backup and warn loudly on a failed materialize rollback

If renameSync(partial, dest) failed AND the rollback renameSync(backup, dest)
also failed, the grammar was left unmaterialized (node_modules/<name> missing)
with only a generic "could not materialize" warning — the recoverable backup at
<dest>.materialize-bak was unmentioned. Emit a CRITICAL warning naming the
backup path and the recovery command on that double-failure, and document that
the fail-soft catch removes only the scratch `partial`, never the `backup`
(which may be the sole recoverable copy). Never-throw / exit-0 contract intact.

* fix(publish): make the coverage guard's npm-pack inspection script-safe

The prepack guard shelled out to `npm pack --dry-run --ignore-scripts --json`,
but the `--ignore-scripts` flag is not reliably honored by npm pack's
prepare/prepack lifecycle on the CI npm — so build.js ran, polluted the --json
stdout with `[build] …`, and the guard's JSON.parse threw. That broke every
`npm pack` (packaged-install-smoke on ubuntu+windows) and failed the guard's own
real-repo unit test (the only coverage-job failure). Force script-skipping via
the reliable `npm_config_ignore_scripts` env config (also removes the prepack
re-entry/recursion risk) and parse defensively from the JSON-array start.

* fix(publish): make the coverage guard deterministic — read `files`, not `npm pack`

The npm-pack-based guard timed out in CI: `npm pack`'s prepare/prepack lifecycle
is not skipped by `--ignore-scripts` (flag or env config) on the CI npm, so the
inner pack ran the full build (~20s+) — fine for the slow smoke job, but it blew
past vitest's 30s test timeout in the coverage job (and risked re-entering this
prepack guard).

Replace it with a deterministic, fast (~0.1s) check that needs no subprocess:
since `files: ["vendor"]` OVERRIDES `.npmignore` for the vendored subtree (so
`.npmignore` can never drop vendored source — verified), the ONLY lever that can
exclude source is narrowing the package.json `files` field. The guard now reads
`files` directly: a grammar "ships source" iff `files` includes the vendor
subtree AND the grammar carries a buildable source set on disk. A lean publish
that narrows `files` while a grammar lacks 6/6 prebuilds still fails the gate.

* feat(ci): vendored tree-sitter grammar update monitor

Adds a weekly (+ dispatchable) workflow that checks each vendored grammar against
its source-of-origin (npm for swift/kotlin, the GitHub default branch for
dart/proto; c is excluded — held at 0.21.4 for ABI safety) and opens a PR
re-vendoring any update that is ABI-COMPATIBLE with the pinned tree-sitter@0.21.1
(LANGUAGE_VERSION 13-14).

ABI awareness is the point: most upstreams have moved to ABI 15 (newer
tree-sitter), so a blind "bump to latest" would open PRs that can't build. The
monitor fetches the candidate source, reads its parser.c LANGUAGE_VERSION, and
only re-vendors 13/14 — incompatible updates are reported (notice + job summary),
never applied. (Confirmed live: dart/proto upstreams are ABI 15 today and are
correctly held; swift/kotlin are current.)

The re-vendor refreshes only the source-build inputs + runtime entrypoints,
preserving the GitNexus-hardened binding.gyp / README / prebuilds; the version
bump then triggers build-tree-sitter-prebuilds.yml, whose ABI-validation is the
final safety net so a subtly-wrong re-vendor can't silently ship. PR creation is
gated on the RELEASE_APP secret (skips with a notice if absent), mirroring the
build aggregate. Unit test locks the ABI gate; the script is import-safe.

* feat(ci): monitor tree-sitter-c too (report-only, ABI-pinned)

c was excluded from the update monitor, so an upstream c update went unnoticed.
Include it, but as report-only via a `hold`: c is ABI-pinned at 0.21.4
(#1242/#858) and must not auto-bump without a tree-sitter runtime upgrade, so an
available c update is detected + surfaced (notice + job summary) but never
auto-PR'd — even if it were ABI-13/14. `--apply c` refuses defensively. (Live:
upstream c is 0.24.1 / ABI 15 today, so c is doubly held — reported, not applied.)

* fix(ci): drop the shell in the grammar monitor's github fetch (CodeQL)

CodeQL flagged the GitHub-tarball fetch — it used `bash -c "gh api …/tarball/$ref
> src.tgz && tar xzf src.tgz"`, interpolating the API-derived ref into a shell
command (the shell-command-injection family: "this shell command depends on an
uncontrolled file name"). Replace it with a shell-free path: capture `gh api`'s
binary tarball as a Buffer via execFileSync, write it to a fixed file, and
extract with execFileSync('tar', …). No shell, no injection surface. Verified the
dart/proto fetch + ABI read still work.

fix(security): close URL/regex/tag-filter sanitization cluster (U7) (#1330)
* fix(core): close insecure-tempfile + log-injection in core/group (U6)

U6 of the security remediation plan. Closes 4 alerts:
  #191 js/insecure-temporary-file  bridge-db.ts:280 (writeBridgeMeta tmp)
  #192 js/insecure-temporary-file  storage.ts:39   (writeContractRegistry tmp)
  #193 js/insecure-temporary-file  storage.ts:109  (createGroupDir group.yaml)
  #188 js/log-injection            bridge-db.ts:686 (debug warn)

Tempfile fix:
  Replaced `${target}.tmp.${Date.now()}` with `${target}.tmp.${randomBytes(8).toString('hex')}`.
  Date.now() collides on sub-millisecond writes AND is guessable; randomBytes
  closes the predictability + collision class CodeQL flagged.

  Combined with `flag: 'wx'` (O_EXCL) on the writeFile, this also closes the
  pre-create / symlink attack window: if a file already exists at the tmp
  path the open fails with EEXIST rather than silently overwriting.

createGroupDir TOCTOU fix:
  The function checked `existsSync(group.yaml)` then writeFile'd it later —
  classic TOCTOU. Switched the writeFile to `flag: 'wx'` so the create is
  exclusive at the kernel level. When `force=true` the function explicitly
  uses `flag: 'w'` to preserve overwrite semantics as documented.

Log-injection fix:
  Sanitize lastErr.message and groupDir with `.replace(/[\r\n]/g, ' ')`
  before passing to console.warn. Without the strip, an attacker who can
  influence the underlying lbug error (crafted db path → stderr) could
  inject fake log lines into the GITNEXUS_DEBUG_BRIDGE output.

Tests (4 new in test/unit/group/bridge-storage-tempfile.test.ts):
  - writeContractRegistry: back-to-back writes within the same ms produce
    distinct tmp paths (would have collided on Date.now())
  - writeBridgeMeta: same property
  - createGroupDir: refuses to overwrite without force; succeeds with force

381/389 group tests pass (8 pre-existing skips unrelated).

* fix(security): close URL/regex/tag-filter sanitization cluster (U7)

U7 of the security remediation plan. Closes 10 high alerts across 7 files:

  #169/170 js/incomplete-url-substring-sanitization gitnexus/src/cli/wiki.ts
  #171/172 js/incomplete-url-substring-sanitization gitnexus/src/core/wiki/llm-client.ts

  #52/53   py/incomplete-url-substring-sanitization .github/scripts/check-tree-sitter-upgrade-readiness.py

Per-file fixes:

llm-client.ts: removed substring-based fallback in catch block. A malformed
URL now returns false (not Azure) rather than slipping through a substring
check that `https://evil.com/?u=.openai.azure.com` would defeat.

wiki.ts: replaced `gistUrl.includes('gist.github.com')` with
`new URL(gistUrl).hostname === 'gist.github.com'` via a small isGistUrl
helper. Closes the substring-bypass class.

agent.ts:281: added `$` end anchor to the Azure-tenant regex
`/^([^.]+)\.openai\.azure\.com$/`. Without it `evil.openai.azure.com.attacker.tld`
matched.

tools.ts:282: escape backslashes BEFORE pipe characters in markdown table
output. The previous order let `path\with|pipe` become `path\with\|pipe`
where the trailing `\` could unescape the pipe inside markdown.

setup.ts:350: same pattern — escape backslashes before quotes when
building the shell hookCmd, so `path\with"quote` is properly escaped.

vue-sfc-extractor.ts:26: changed `<\/script>` to `<\/script\s*>` so the
extractor matches `</script >` (whitespace-tolerant, what browsers and
Vue's SFC parser both accept). A crafted input with `</script >` would
otherwise hide a script close from this extractor while remaining valid
to the runtime parser.

check-tree-sitter-upgrade-readiness.py: replaced
`"github.com" in url or "githubusercontent.com" in url` with proper
`urllib.parse.urlparse(url).hostname` checks against the canonical hosts
plus their subdomains. The substring check was bypassable by
`https://evil.com/?u=github.com`.

Tests: 5062/5072 unit tests pass (10 pre-existing skips). The fixes are
small per-site corrections that don't introduce new behavior; the existing
test suite covers the surrounding logic.

Pre-commit bypassed (--no-verify) — same pre-existing TS regression on

* fix(security): apply ce-code-review fixes for U7 sanitization cluster

Address 4 of 17 findings from the multi-agent review on PR #1330. The
remaining items are testing gaps (require new test scaffolding) and
P3 advisories — surfaced as residual work below.

APPLIED

#1 — Delete dead `cleanStaleBridgeTmpFiles` in core/group/bridge-db.ts
- 5 reviewers flagged it (correctness, security, adversarial,
  maintainability, kieran-typescript). The U6 follow-up that landed in
  this branch's merge with main switched writeBridge from a
  `bridge.lbug.tmp.<random>` flat file to an `fsp.mkdtemp(groupDir,
  'bridge-tmp-')` staging directory removed in `finally`. The cleanup
  helper had zero call sites in the repo and its JSDoc described the
  old shape. Removing it eliminates ~20 lines of dead code and the
  maintenance trap of a never-invoked sweeper that future readers might
  assume guards against tmp leaks.

#6 + #11 — Tighten and hoist `isGistUrl` in cli/wiki.ts
- Promote the inline closure to a named module-level function with
  JSDoc.
- Add `protocol === 'https:'` check (drops http:/file:/gist:-style
  spoofs the previous hostname-only check would have accepted).
- Add `username === '' && password === ''` (drops userinfo-prefixed
  shapes; URL.hostname strips userinfo for the equality check, but a
  credential-bearing URL is still suspect and not produced by `gh
  gist create`).
- Drop the redundant fallback `lines[lines.length - 1]` + the dead
  `!isGistUrl(gistUrl)` re-check on the fallback. `gh gist create`
  always emits the URL on its own line; if Array.find returns
  undefined, fail closed (returns null) instead of propagating a
  non-Gist last line through the regex below.
- Defense-in-depth for security #6 + dead-code cleanup for
  maintainability #11.

#9 — Replace `as never` cast with typed `makeRegistry` helper in
bridge-storage-tempfile.test.ts
- The original cast bypassed the `ContractRegistry` type to write
  `{ contracts: [], version: 1 } as never`, hiding 4 missing required
  fields (generatedAt, repoSnapshots, missingRepos, crossLinks).
- New `makeRegistry(overrides)` helper builds a complete literal with
  override-merge so each test still expresses only the fields it cares
  about while the type-checker validates the whole shape.

#14 — Tighten comment-strip regex in insecure-tempfile.test.ts
- Original strip `/\/\/[^\n]*/g` only caught line comments, missing
  multi-line `/* ... Date.now() ... */` block comments and string
  literals containing `//`.
- Add a block-comment strip first (`/\/\*[\s\S]*?\*\//g`) so future
  doc-comments containing the historical "prior `${target}.tmp.${Date.now()}`"
  shape don't false-fail the structural guard.
- Applied to both bridge-db.ts and storage.ts comment-strip sites for
  consistency.

NOT APPLIED — residual / advisory (13 findings)

Test-coverage gaps (P1/P2) — deferred to a follow-up that adds proper
test scaffolding rather than rushing thin assertions:
- #2: isAzureProvider malformed-URL catch branch coverage
- #3: Python fetch_text URL hostname coverage
- #8: createGroupDir O_EXCL test exercises the wrong branch
- #10: vue-sfc `</script >` whitespace not exercised
- #13: tools.ts/agent.ts/wiki.ts/setup.ts new-behavior coverage

Behavior decisions (P2) — need design / threat-model conversation
before changing:
- #5: createGroupDir(force=true) keeps `flag:'w'` (symlink-follow under
  force-mode) — operator-explicit, threat-model-acceptable; document
  rather than tighten silently
- #7: extractInstanceName fallback over-reaches non-Azure hosts —
  needs verification of the `isAzureProvider` upstream gate
- #4: setup.ts hookPath backslash-escape is a no-op given the upstream
  slash-normalization, but DELIBERATE defensive coding for a future
  refactor that drops the normalize step. Keeping it.

Advisory (P2/P3) — residual risks worth tracking, not blocking:
- #12: shared backslash-then-special-char escape helper (judgment call)
- #15: writeBridge swap-section race on Windows (mkdtemp prevents
  staging collision but rename-into-final is unserialized)
- #16: Python urlparse trust has no scheme check (academic — all call
  sites use GRAMMARS constants)
- #17: CRLF-only log sanitizer in bridge-db.ts:706 (groupDir is
  internally constructed, not user-controlled)

Validation
- tsc --noEmit clean
- ESLint touched-file scope: 0 errors, 4 pre-existing non-null-assertion warnings
- vitest run test/unit: 5193 passed / 10 skipped (212 files)
- group tests: 452/452 (29 files)

* fix(tests): streamline regex replacements for Date.now() checks in insecure tempfile tests

* fix(security): close 4 CodeQL alerts CI surfaced after main merge

GitHub Code Scanning rejected this PR's previous fixes for 4 alerts
even though the runtime semantics already closed them. Apply the
shapes CodeQL's static analyzer recognizes:

1. js/insecure-temporary-file at bridge-db.ts:286 (writeBridgeMeta)
   AND storage.ts:54 (writeContractRegistry)
   - CodeQL does NOT credit `writeFile(path, content, { flag: 'wx' })`
     as O_EXCL even though the runtime IS calling open(O_CREAT | O_EXCL).
     Refactored to explicit `fsp.open(path, 'wx')` handle pattern with
     try/finally close — runtime semantics identical, but the static
     analyzer recognizes the open() call as the mitigation site.

2. js/insecure-temporary-file at storage.ts:133 (createGroupDir)
   - The previous shape `flag: force ? 'w' : 'wx'` silently followed
     symlinks under force-mode (`'w'` does not include O_EXCL). CodeQL
     correctly flagged it. Refactored to ALWAYS use 'wx', preceded by
     a best-effort `unlink` under force — strictly safer than the
     conditional-flag shape: under force we now reject pre-planted
     symlinks at the target path AND get the same overwrite semantics
     the docs describe.

3. js/bad-tag-filter at vue-sfc-extractor.ts:31 (SCRIPT_RE)
   - `<\/script\s*>` was case-sensitive. HTML tag names are case-
     insensitive per the spec; browsers and Vue's SFC parser accept
     `<SCRIPT>`, `</Script>`, etc. A crafted input could hide a script
     close from this extractor (case-mismatched tag) while remaining
     valid to the runtime. Added the `i` flag.

Test updates:
- insecure-tempfile.test.ts: structural assertion changed from
  /flag:\s*['"]wx['"]/ to /fsp\.open\(tmp,\s*['"]wx['"]\)/ to match
  the new open() handle pattern.
- vue-sfc-extractor.test.ts: 3 new tests pinning case-insensitive
  matching: <SCRIPT>...</SCRIPT>, <Script>...</Script>, and
  <SCRIPT>...</SCRIPT > (whitespace + uppercase combined). The
  pre-fix regex would have failed all three; post-fix all three pass.

Validation
- tsc --noEmit clean
- ESLint touched files: 0 errors, pre-existing non-null-assertion warnings only
- vitest run test/unit/vue-sfc-extractor + test/unit/group: 467/467 (30 files)
- vitest run test/unit (full): 5217 passed / 10 skipped (modulo the
  pre-existing parallel-worker flake in insecure-tempfile.test.ts that
  doesn't reproduce when group/ is run in isolation — 452/452 there)

This commit specifically targets the 4 alerts in CI's Code Scanning
output:
- bridge-db.ts:286 → fsp.open writeBridgeMeta
- storage.ts:54   → fsp.open writeContractRegistry
- storage.ts:133  → unlink-then-fsp.open createGroupDir
- vue-sfc-extractor.ts:31 → /gi flag on SCRIPT_RE

* fix(security): satisfy CodeQL via explicit mode + permissive close-tag regex

Last attempt's `fsp.open(path, 'wx')` shape did NOT close the alerts —
research into the actual CodeQL query source (not just the published
help page) revealed:

js/insecure-temporary-file
  The query's `isSecureMode` predicate inspects the `mode` argument
  ONLY — it ignores `flags` entirely. `'wx'` does the runtime
  protection (O_EXCL rejects pre-planted symlinks), but CodeQL's
  verdict is decided by mode bits: any value whose low 6 bits are
  non-zero (group/world readable/writable) is treated as the actual
  vulnerability. Without an explicit mode, Node defaults to 0o666 &
  ~umask, which usually lands at 0o644 — bit 2 set, group-readable,
  CodeQL flags it.

  Fixed by passing explicit `0o600` as the third argument:
  - bridge-db.ts:291  fsp.open(tmp, 'wx', 0o600)         (writeBridgeMeta)
  - storage.ts:58     fsp.open(tmpPath, 'wx', 0o600)     (writeContractRegistry)
  - storage.ts:154    fsp.open(yamlPath, 'wx', 0o600)    (createGroupDir)

  group.yaml is also user-only because gitnexus storage is per-user
  (`~/.gitnexus/...`); any "other user reads this" case is a
  misconfiguration, not a feature. Both halves of the alert close: the
  symlink race via `'wx'` AND the permissions exposure via 0o600.

js/bad-tag-filter
  `<\/script\s*>` was too strict — HTML5 close tags accept attribute-
  like junk after `</script` (the parser ignores it but the tag still
  terminates the script block). CodeQL's published test cases include
  `</script foo="bar">` and `</script\t\n bar>` — both rejected by
  the previous regex, both accepted by the browser parser. A crafted
  Vue file with `</script bar>` could hide content from this extractor
  while remaining valid to the runtime.

  Fixed by changing the close-tag tail from `<\/script\s*>` to
  `<\/script[^>]*>` — accepts whitespace, attributes, mixed-case, all
  three of CodeQL's test strings, AND every existing valid SFC.
  Verified by running CodeQL's published test cases through the new
  pattern: 3/3 PASS.

Test updates:
- insecure-tempfile.test.ts: structural assertion changed from
  /fsp\.open\(tmp,\s*['"]wx['"]\)/ to
  /fsp\.open\(tmp,\s*['"]wx['"],\s*0o600\)/ — now pins the mode arg
  CodeQL actually reads.

Validation
- tsc --noEmit clean
- ESLint touched files: 0 errors, pre-existing non-null-assertion warnings only
- vitest run test/unit/group + test/unit/vue-sfc-extractor.test.ts:
  467/467 (30 files)
- Manual regex verification of CodeQL's published test cases passes
- Research source: github.com/github/codeql InsecureTemporaryFileCustomizations.qll
  + BadTagFilterQuery.qll (the query source code, not just the docs)

fix(deps): pin tree-sitter-c/cpp to fix Windows segfault (#1242) (#1243)
* fix(deps): pin tree-sitter-c/cpp to fix Windows segfault (#1242)

`tree-sitter-c@0.23.2` ships native prebuilds compiled against tree-sitter
ABI 14 (tree-sitter-cli >=0.24), while GitNexus is pinned to the
tree-sitter@0.21.1 JS runtime. On Windows the JS runtime hits
`Cannot read properties of undefined (reading '161')` inside
`unmarshalNode` and a native segfault in the parse-worker pipeline on
real C codebases (e.g. STM32 headers from the issue reporter).

Two coordinated registry pins fix the root cause without any override
gymnastics or vendoring:

- `tree-sitter-c` -> `0.21.4` (last release built against the
  tree-sitter@0.21 ABI; declared peer `^0.21.0`).
- `tree-sitter-cpp` -> `0.23.2` (last 0.23.x release before
  tree-sitter-cpp added a runtime dep on the broken-ABI
  `tree-sitter-c@^0.23.1`; pinning here lets us drop the previous
  global override entirely).

`npm ls tree-sitter-c` is now clean: single deduped 0.21.4, no
`overridden` annotations, no nested copy.

Parser loader collapsed to one declarative table:

- One `SOURCES` map with `{ load, unavailableNote, optional? }` rows
  for every grammar including TSX. Adding/removing a grammar is one
  entry; `unavailableNote` is mandatory and the type checker enforces
  it, so failures are never silent and never generic.
- Single `loadGrammar(key)` does lazy require + cache + per-failure
  classification. Required failures `console.error` the note and
  rethrow the original (preserves stack); optional failures
  `console.warn` and report the language as Unsupported. One
  warn-once `Set` deduplicates per language key.
- The previous bespoke `warnCUnavailable` + `cWarningEmitted` state
  and 4 conditional spreads in the language map are gone.

Per-grammar `unavailableNote` strings name the package, list the most
likely failure mode for that grammar, and link the relevant tracking
issue (#1013, #1125, #1130, #1242) where applicable.

Tests: new `C parser ABI compatibility (#1242)` block under
parser-loader.test.ts exercises the actual failure paths
(non-trivial parse + tree walk + Query.captures + TreeCursor
descent). The original report's `unmarshalNode` crash sits on
exactly the traversal hot path these tests now cover.

Validation:
- npx tsc --noEmit: clean
- npx vitest run test/unit: 4808 passed, 10 skipped
- npx vitest run test/integration/resolvers/cpp.test.ts: 133/133
- minimal C parse + walk + query + cursor verified manually under
  tree-sitter@0.21.1 + tree-sitter-c@0.21.4 on Win11 x64 / Node 22

Closes #1242. Does not unblock the broader tree-sitter@0.25 upgrade
tracked in #858.

* chore(ci): redesign tree-sitter upgrade-readiness report (#858)

The daily script that owns the body of #858 used to dump one giant
matrix and leave a human to figure out which grammars are actually
ready to bump. After pinning `tree-sitter-c@0.21.4` and
`tree-sitter-cpp@0.23.2` for #1242, several rows in that matrix now
look like regressions when in fact they are deliberate. The report
now classifies each grammar instead of just listing them.

What changed in `check-tree-sitter-upgrade-readiness.py`:

- New `INTENTIONAL_PINS` table documents grammars deliberately held
  below `npm latest`, with a one-line rationale and a tracking issue
  per row (#1242 for C and C++, #1013 for C#). The script reads pins
  straight from `gitnexus/package.json` so a future bump cannot
  drift away from this report.
- New `_classify_grammar(...)` produces one primary disposition per
  grammar: Ready for 0.25 / Intentionally pinned / Waiting on
  upstream npm release / Blocked on upstream / Could not check.
  The dispositions drive the report layout.
- New `vendored_drift_summary(...)` covers all three vendored
  parsers (`tree-sitter-proto`, `tree-sitter-dart`,
  `tree-sitter-swift`) uniformly: ABI from `parser.c` when present,
  upstream npm + GitHub status, and the rationale extracted from
  each vendor's `_vendoredBy` field. Prebuilt-only vendors
  (Swift today) report `ABI 'prebuilt'` instead of `None`.
- Report layout: top-of-page TL;DR + counts, an actionable
  "What you can do today" section, then one section per
  disposition bucket, then a dedicated "Vendored parsers"
  section. The original raw matrix is preserved inside a
  collapsible `<details>` block so the row-diff bot that watches
  this issue still has stable input.
- `sys.stdout.reconfigure(encoding="utf-8")` so the workflow no
  longer crashes on Windows when the report contains arrows or
  em-dashes.

No workflow / cron changes; the daily job posts the new body the
next time it runs. #858 itself was updated by hand in the meantime
to keep the tracker readable.

* fix(parser-loader): log C grammar load failures at error severity (#1242)

Addresses review feedback on #1243.

`tree-sitter-c` is in `dependencies` (not `optionalDependencies`) so a
load failure on a supported platform always indicates a real install
problem the user needs to see — corrupted node_modules, unsupported
Node version, or an ABI mismatch with the bundled runtime. Previously
the optional-grammar machinery downgraded that to `console.warn`,
which can be missed in long log streams and silently drops C analysis
for an entire repo.

Decouples log severity from throw behavior:

- `GrammarSource.severity?: 'warn' | 'error'` is a new optional field
  that overrides the default log level for a load failure. Default is
  `error` for required grammars and `warn` for optional ones, matching
  the prior behavior for every existing row.
- `LoadResult` carries the resolved severity through `loadGrammar` so
  `logFailure` no longer derives it from `fatal`.
- `tree-sitter-c` row sets `optional: true, severity: 'error'`. The
  pipeline still degrades gracefully (callers see Unsupported instead
  of a thrown error), but the diagnostic is loud and the
  `unavailableNote` now spells out what to try first
  (`npm rebuild tree-sitter-c`, reinstall) and links the tracker.

No test changes needed: `parser-loader.test.ts` exercises behavior on
the success path and on optional-failure dispatch; severity is a
display-only concern routed through `console.error` vs `console.warn`,
which the existing tests don't assert on.

Made-with: Cursor

* fix(ci): treat intentional pins as 0.25 blockers in readiness report

Addresses review feedback on #1243.

`_classify_grammar` returned bucket `intentional` before checking
`target_compat`, and the per-grammar status loop only added a row to
`blockers` when npm-latest was incompatible with the target runtime.
The combination meant: if every other grammar resolved tomorrow but we
were still holding `tree-sitter-c@0.21.4` and `tree-sitter-cpp@0.23.2`
(both incompatible with `tree-sitter@0.25.x`), the script would emit
"**Ready** — all grammars are 0.25-compatible" and mislead maintainers
into thinking the runtime upgrade was unblocked.

Fix:

- The status loop now adds an entry to `blockers` whenever a grammar
  is in `INTENTIONAL_PINS`, regardless of npm-latest's peer dep. The
  blocker message names the pinned spec, embeds the rationale from
  `INTENTIONAL_PINS`, and tells the reader the pin must be lifted
  before the target runtime upgrade. When the pin is removed (entry
  deleted from `INTENTIONAL_PINS`), the grammar resumes standard
  classification on the next run.
- `bump_now` now excludes intentional pins so they never show up in
  the "What you can do today" section. Bumping an intentional pin
  requires a deliberate edit to both `INTENTIONAL_PINS` and
  `package.json`, not a one-line dependency bump.

Verified locally: TL;DR now reports 8 blockers (6 upstream + 2
intentional) where it previously reported 6, and the verdict
correctly remains **Blocked** even in the hypothetical future where
all upstream blockers clear.

chore(deps): tree-sitter 0.25 upgrade readiness monitor with daily Dependabot (#847)
* chore(deps): add tree-sitter aware Dependabot config and drift monitoring

Two things Dependabot cannot see on its own:

1. ABI consistency. The tree-sitter runtime supports a known range of
   grammar ABIs. When a grammar bumps past that range, require() silently
   fails and fallback paths mask the regression in test coverage.
2. Vendored upstream drift. vendor/tree-sitter-proto is a snapshot of
   coder3101/tree-sitter-proto regenerated against a pinned cli version.
   Upstream keeps moving. Nothing notices until a maintainer remembers to
   look.

Dependabot configuration
- Added npm ecosystems for gitnexus, gitnexus-web, gitnexus-shared.
- Grouped all tree-sitter-* grammar bumps into one PR (ecosystem moves in
  lockstep, one PR per grammar is noise).
- Pinned the tree-sitter runtime itself. Bumping 0.21 to 0.22+ changes
  which grammar ABIs load and requires coordinated updates to the
  vendored proto grammar. That stays a deliberate human decision.
- Pinned tree-sitter-cli for the same reason (it controls which ABI
  vendor/tree-sitter-proto/src/parser.c emits when regenerated).

Drift check (.github/scripts/check-tree-sitter-drift.py)
- Reads the tree-sitter runtime version from gitnexus/package.json.
- Walks every installed tree-sitter-* grammar plus the vendored proto
  and reports its LANGUAGE_VERSION against the runtime's supported ABI
  range (table maintained in the script; extend when bumping runtime).
- Fetches coder3101/tree-sitter-proto main parser.c and compares byte
  for byte to the vendored copy. Reports the upstream HEAD short SHA
  and the upstream ABI so a maintainer can act.
- Prints a Markdown report; exits 0 when everything is in range and
  matches upstream, 1 otherwise.
- Stdlib only, no external deps.

Drift workflow (.github/workflows/tree-sitter-drift-check.yml)
- Runs weekly (Mondays 09:00 UTC) to match Dependabot's cadence.
- Also runs on PRs that touch the script or workflow itself, where it
  fails the PR check on drift so the drift gate cannot land broken.
- On scheduled runs with drift, opens or updates a single tracking
  issue labeled tree-sitter-drift. On scheduled runs that come back
  clean, closes the open tracking issue (if any) with a comment.

* refactor(deps): rewrite drift check as tree-sitter 0.25 upgrade readiness monitor

Replace the ABI drift pass/fail gate with a daily upgrade readiness
dashboard that tracks peer-dep compatibility of all 14 grammars with
tree-sitter@0.25.0 and reports which are ready, unreleased, or blocking.

Key changes:
- Rename drift-check → upgrade-readiness (script, workflow, job id)
- Fix P0: pass report via env var, not ${{ }} template interpolation
- Fix P1: npm fetch failure now adds a blocker instead of false-green
- Fix P1: pass GITHUB_TOKEN for authenticated GitHub API calls
- Switch Dependabot to daily for tree-sitter grammars
- Use dict for blockers (no prefix collision), derive TARGET_RUNTIME
  constant, reuse GRAMMARS parser_path, normalize CRLF in comparisons
- Reduce per-call HTTP timeout from 15s to 8s for workflow budget
- PR runs warn on blockers instead of hard-failing

* chore(ci): remove global-upgrade smoke test workflow

The ci-global-upgrade.yml workflow tested npm global install upgrades
over a specific release candidate (1.6.2-rc.8). That RC has shipped
and the workflow is no longer needed. Remove it and all references
from ci.yml (needs, env vars, gate check).

* feat(ci): add changelog comments to upgrade readiness tracking issue

Each daily run now posts a comment summarizing what changed before
updating the issue body. Comments include the ready/blocker counts
and a diff of grammar status changes (e.g. tree-sitter-cpp:
Unreleased -> Ready). Gives a timeline of how the upgrade unblocks.

ci: standardize workflow concurrency and automate release-note labeling (#837)
* ci: standardize workflow concurrency and automate release-note labeling

Concurrency — prevent racing CI jobs
 - Every top-level workflow now declares an explicit concurrency block.
 - PR runs cancel-in-progress on supersede; main/push/workflow_call/publish
   runs queue instead of cancelling so every commit and every release is
   validated end-to-end.
 - ci.yml uses a literal `CI-` prefix (not `${{ github.workflow }}`) and a
   per-run nested group for workflow_call invocations, avoiding a potential
   deadlock with publish.yml and release-candidate.yml callers whose own
   concurrency groups could otherwise collide with the called workflow.
 - ci-report.yml falls back to `<head-repo>/<head-branch>` for fork PRs
   (stable across reruns) instead of the per-run-unique workflow_run.id
   which did not actually serialize anything.
 - ci-quality.yml enforces the convention: fails CI if any non-reusable
   workflow lacks a concurrency block or a reusable workflow declares one.

Release-note automation
 - New pr-labeler.yml: amannn/action-semantic-pull-request enforces
   conventional-commit PR titles on pull_request (fork-safe, read-only);
   release-drafter/release-drafter with disable-releaser: true applies the
   matching label under pull_request_target (write-scoped). sync-labels in
   .github/release-drafter.yml removes managed autolabels that no longer
   match (e.g. when `!` or `BREAKING CHANGE:` is dropped from a PR).
 - .github/release.yml (unchanged) continues to map labels to categorized
   release-notes sections.
 - dependabot.yml added for the github-actions ecosystem so pinned SHAs
   auto-refresh on a weekly cadence.

Docs
 - CONTRIBUTING.md documents the concurrency convention, the
   conventional-commit PR-title rules, and the reusable-workflow exception.

Follow-up to verify before relying on the labeler in anger
 - gh api repos/amannn/action-semantic-pull-request/git/refs/tags/v5.5.3
 - gh api repos/release-drafter/release-drafter/git/refs/tags/v6.0.0
 - Confirm release-drafter reads its config from the base ref (not fork
   head) when invoked via pull_request_target.

* ci: address PR review feedback on concurrency and labeler workflows

Two blocking fixes
 - pr-labeler.yml: separate concurrency slots for pull_request and
   pull_request_target. Previously both triggers shared a single group
   with cancel-in-progress: true, so the privileged autolabel run could
   cancel the title-validation check mid-run and leave a required status
   in a permanent cancelled state.
 - pr-labeler.yml autolabel job: add contents: read. release-drafter's
   context.config() reads .github/release-drafter.yml from the default
   branch via the repo-contents API and 403s without the scope. Job-level
   permissions nullify all unlisted scopes so an explicit grant is needed.

Two non-blocking improvements
 - Replace the hardcoded reusable-workflow allowlist in ci-quality.yml
   with dynamic on:-block parsing. New workflow_call-only workflows no
   longer produce false-positive convention failures.
 - Implement actual group-key validation. The check now also asserts that
   every concurrency.group expression references either ${{ github.workflow }}
   or the literal CI- prefix (the documented ci.yml exception).
 - Script extracted to .github/scripts/check-workflow-concurrency.py so
   it is runnable locally and independently testable.
