* feat(analyze): --memory-budget flag with heap-limit override and worker-pool degradation (#3137)

Adds an explicit `--memory-budget <mb>` CLI flag that overrides the
RAM/cgroup auto-sized main-thread heap ceiling for the parse phase:

- CLI validation (integer >= 200 MB) before bar.start(), matching the
  --workers pattern
- Threaded CLI → runFullAnalysis → PipelineOptions → parse-impl as
  memoryBudgetBytes
- parse-impl resolves the heap limit as budget ?? v8.heap_size_limit, so
  both the preflight projection warning and the #2649 mid-loop abort
  probe honor the budget
- Graceful degradation: when the projected heap need exceeds the budget
  at the computed pool size, the pool shrinks (never below 1, never
  above the operator's --workers) before sub-batch math and pool
  construction, so all downstream consumers see the degraded size

Omitting the flag keeps the auto-sizer path byte-identical.

* feat(analyze): collapse rebuild-gate log into one summary + persist needsFullRebuild verdict (#3137)

The nine meta-mismatch rebuild gates (pdg mode, content retention,
schema fingerprint, graph-write collapse, analysis features, Spring
vendor prefixes, runner identity, FTS CJK mode, embedding dims) each
logged individually and set force:true independently. An upgrade that
trips several at once printed a scattered wall of near-identical
warnings.

- Gates now collect into rebuildReasons[]; a single summary block
  prints them (inline for one, numbered for many) and sets force once.
  Per-gate Tip text is preserved verbatim inside the entries.
- The verdict persists to meta (needsFullRebuild: {reasons, recordedAt})
  BEFORE the rebuild starts. If the rebuild is interrupted, the next
  run announces the recorded reasons up front instead of quietly
  attempting an incremental write on a half-rebuilt index — the gates
  may not all re-fire against a wiped DB.
- The verdict is cleared on the next successful completion (the final
  meta does not carry the field forward).

Semantics unchanged: every gate was already evaluated (none
early-returns), force is idempotent, and a rebuild happens iff at
least one reason fired.

Refs #3137

* refactor(cli): share one integer flag parser across analyze, watch, and wiki

Replace the duplicated Number.isInteger checks for --workers, --embeddings,
the positive env-backed analyze flags, the watch interval flags, and wiki's
--timeout/--retries with parseIntegerOption (per-flag minimum, optional
scale for the safe-integer bound). User-facing messages are unchanged.

* fix(analyze): make --memory-budget set the real V8 heap through the respawn

The budget now drives ensureHeap's existing respawn instead of a parse-phase
override, so the #2649 preflight, mid-loop abort, remedy text, and GC pacing
all see one heap limit. The respawn sizes old space plus three semi-spaces to
equal the budget, the child resolves as already at the budget (no second
respawn), and GITNEXUS_HEAP_LIMIT_SOURCE drives budget-aware OOM advice.
Budget validation moves to the preAction hook so analyze and watch reject a
bad value before any respawn. Removes the pool-shrink block and the
memoryBudgetBytes plumbing through PipelineOptions and run-analyze.

* docs(analyze): describe --memory-budget accurately and translate its help

The help text claimed graceful worker-pool degradation, which no longer
exists; it now says the flag sets the main-thread V8 heap and that parse
workers keep their own caps. Wires the option through the help i18n map
with en and zh-CN strings, and documents it in both READMEs and the
out-of-memory troubleshooting section.

* feat(analyze): add a pure rebuild-reason collector

One collector per run holds keyed rebuild reasons, merges by key, flattens
reasons stored by an interrupted rebuild into one recovery entry, validates
stored reasons on read, and formats the single up-front summary plus one
follow-up line for reasons added after the pipeline.

* fix(analyze): route every forced rebuild through one reason collector

Every path that forces a full rebuild (the nine meta gates, --force,
--skills, --no-parse-cache, --drop-embeddings, --repair-fts retention,
Spring Actuator, AsyncAPI, shared-store graph gaps, dirty-flag recovery,
the post-pipeline capability gate, and the #2409 escalation) now adds a
keyed reason to one collector. The rebuild decision is applied from the
collector at fixed checkpoints, one summary prints right before the
pipeline, and late reasons print one follow-up line. The escalation stays
non-forcing. runFullAnalysis returns the collected keys, which replaces the
runner-identity source-regex test with a behavior test. Removes the separate
needsFullRebuild field and its announcement, and stops folding --skills and
--no-parse-cache into --force.

* fix(analyze): persist rebuild reasons on the existing crash marker

Every incrementalInProgress writer (the full-rebuild stamp before the wipe,
the incremental pre-write, saveIncrementalDirtyState including the #2409
escalation, and buildFtsDirtyStamp) now carries the collected reasons into
the active slot's metaDir, so an interrupted rebuild explains itself on the
next run through one merged recovery entry. A successful run still clears
the marker and its reasons; the FTS-park recovery clears them without
forcing.

* test(analyze): cover every rebuild-reason key through runFullAnalysis

Add a coverage table that the typechecker keeps complete: every
RebuildReasonKey maps to a test file that drives it through
runFullAnalysis and asserts the returned key. Adds the missing
graph-write-collapse and drop-embeddings drivers, asserts the key in the
existing pdg-mode, spring-vendor-prefixes, cjk-segmentation, and
embedding-dims tests, and removes plan-local IDs from test names and
comments.

* fix(review): apply review findings

- A --max-old-space-size pin equal to --memory-budget no longer counts as
  the exact budget heap (V8 adds the young generation on top); only the
  budget-respawned child skips the respawn, so the limit really equals the
  budget.
- Snapshot the analyze env before ensureHeap and restore
  GITNEXUS_HEAP_LIMIT_SOURCE, so a kept process does not leak its heap
  source into a later programmatic analyzeCommand call.
- --skills and --no-parse-cache keep the forced storage requirements they
  had before force stopped being folded from them.
- Merge the duplicated follow-up announcement into one helper and fix a
  stale --drop-embeddings comment.
- The rebuild-reason coverage table no longer greps driver files for the
  key string; add tests for a programmatic invalid budget and the
  multi-cause interrupted-rebuild text.

* fix(review): don't announce the escalated write as a full rebuild

The #2409 escalation is a non-forcing reason, but its follow-up line used
the 'Full rebuild also required' lead. A follow-up that carries only
non-forcing reasons now leads with 'Write plan changed'.

* docs(analyze): document GITNEXUS_HEAP_LIMIT_SOURCE in the env table

CONTRIBUTING requires every new GITNEXUS_* variable to have a row; this one
is internal (set by analyze itself) and exists so OOM advice points at
--memory-budget.

* fix(review): address GitNexus review threads on #3386

- heapPressureRemedy measures pressure against the real auto-sized cap
  (heapCapMbFor) instead of a flat 0.75 x RAM, and no longer tells a
  GITNEXUS_MEMORY=off run with no pin to drop a pin that does not exist.
- toStored() persists the interrupted rebuild's reasons first, as documented.
- ensureHeap's doc names which paths leave GITNEXUS_HEAP_LIMIT_SOURCE unset.
- The heap-respawn suite restores the caller's GITNEXUS_MEMORY.
- The non-forcing follow-up test rejects any 'full rebuild' wording.

* fix(review): require both budget flags and check key coverage at runtime

- A budget-respawned child is recognized only when the inherited heap-source
  marker comes with both the budget's old-space and semi-space flags; the
  marker alone is an inherited env var, not proof. The old-space parser is
  generalized to any V8 size flag instead of copying its regex.
- REBUILD_REASON_KEYS is exported and RebuildReasonKey derives from it, so the
  coverage table is checked at runtime (CI does not type-check test files).

* fix(review): don't claim a full rebuild in a non-forcing summary

formatSummary and formatFollowUp now share one leadFor helper, so a block
of only non-forcing reasons reads 'Write plan changed' in both.

fix(auto-sync): HTTPS remotes, OpenSSH image, and rc embeddings (#3378)
* fix(docker): install OpenSSH in the CLI runtime image

Auto-sync requires git SSH remotes, but the published image omitted
openssh-client so every clone failed with ssh: not found.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): accept HTTPS remotes and reclone failed checkouts

Allowlisted HTTPS URLs can clone without SSH keys, and a timed-out
clone with no remote.origin is quarantined instead of blocking forever.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): honor .gitnexusrc embeddings and warn on empty vectors

Auto-sync analyze now reads embeddings from the clone's project config,
and query reports when an index has no vectors so keyword fallback is visible.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(review): warn when CodeEmbedding table is missing (U5)

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(ci): wrap long openssh-client test line for prettier

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(query): keep keyword-only indexes off query.warning

Empty or missing CodeEmbedding is the default index. Put the #3372 notice in a once-per-backend log line so FTS-success query results stay warning-free.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(review): bound rc reads and quarantine only a missing origin

Drop the implementation plan from the branch. Auto-sync reads .gitnexusrc through the bounded control-file reader, and a git config failure no longer relocates a live checkout. The same allowlisted repo can switch between SSH and HTTPS without a refused pull.

feat(storage): share one index store across linked worktrees and sibling clones (#3374)
* feat(storage): resolve the shared sibling-store identity and layout (#3352)

Linked worktrees of one repository resolve to one store under
GITNEXUS_HOME/stores/<key>, keyed by the canonical git common dir. The
resolver reads the .git entry directly, so hot paths spawn no git. Slot
naming moves to a leaf module so storage-resolver and shared-store do not
import each other.

* feat(storage): resolve a shared checkout's graph and existing store slot (#3352)

getStoragePaths reads a flat slot's recorded graphPath only for checkout
slots under the stores directory; other paths keep <storagePath>/lbug with
no I/O. A recorded path outside the store's commit graphs is ignored.
resolveStoragePath falls back to an existing store slot for an
unregistered checkout, so reads never move to an empty slot.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* feat(analyze): share one immutable commit graph across clean worktrees (#3352)

A linked worktree writes its own slot in the shared store. A new slot
is seeded with a pointer to the nearest commit graph, so a clean
checkout at an indexed commit takes the up-to-date path and writes no
graph. A checkout with local changes gets a copy-on-write private
graph before its first write. After a successful run, a clean checkout
at HEAD publishes its graph into commits/ under a store lock, or drops
it when that commit graph already exists. Commit graphs are never
written after publish.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* feat(analyze): seed a worktree's graph from the nearest index (#3352)

A new shared slot is seeded from the store's commit graph nearest to
HEAD, else from this checkout's or the main checkout's
repository-local index (copied under that index's lock, source left in
place). The run that follows is up to date or incremental instead of a
full build. If a pointed-at shared graph has been removed, analyze
falls back to a full build instead of an incremental update over a
missing baseline.

* feat(analyze): keep one parse cache per shared store (#3352)

Linked worktrees read and write the parse cache and durable ParsedFile
store under the store's caches/ directory. Before pruning, a run folds
in the chunk keys recorded by every member slot and commit graph, and
the fold, prune and save run under a store-wide cache lock so one
member never evicts another's live chunks.

* feat(clean): remove only what no shared-store member references (#3352)

Deleting a shared checkout slot (clean, clean --all, remove, and the
server delete route) recounts references under the store's publish
lock and deletes commit graphs no member points at, then the store
itself once empty. A graph that cannot be deleted (open on Windows) is
reported and kept for the next pass. clean --gc also drops member slots
whose worktree is gone or no longer resolves to the store.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* feat(analyze): let a clone opt in to a shared store with --share-with (#3352)

An independent clone joins a linked worktree's shared store only with
analyze --share-with <repo>, and only when its normalized origin URL
matches that member's (credentials stripped, as #2054 compares). The
registry remembers the choice. --no-share moves an opted-in clone back
to its own .gitnexus and reclaims its old slot; linked worktrees always
share and are pointed at GITNEXUS_SHARED_STORE=off instead.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): count a shared checkout's commit graph as its code index (#3352)

A clean shared checkout reads a commit graph and owns no graph file, so
the code-index presence check made status report it unindexed and
registry validation skip it. The check now follows the slot's
validated graphPath.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* feat(storage): adopt existing worktree indexes and report shared-store state (#3352)

A shared checkout gets <repo>/.gitnexus/store.json pointing at its store
slot; resolution follows it only when it names that checkout's own slot.
An existing local index seeds the slot and is left in place. status
(text and --json) and doctor report the store, whether the graph is
shared or private, and any leftover local index, which
clean --local-index removes while keeping the pointer. With
GITNEXUS_SHARED_STORE=off a previously shared checkout indexes into its
own .gitnexus again and never writes a commit graph.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* feat(mcp): read the graph a shared checkout points at (#3352)

MCP, the HTTP API, group sync, augmentation, and the Claude hook (all
three byte-identical copies) resolve a flat slot's graph through
resolveGraphPath instead of joining 'lbug' onto the storage path, so
checkouts at one commit share one open database. The embeddings writers
(embeddings sync and the server embed job) take a private copy first
and never write an immutable commit graph. The post-analyze settle
probe accepts fresh metadata that points at an existing commit graph.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* refactor(storage): reuse helpers across the shared-store code (#3352)

One graph-clone helper replaces two copy-then-rename blocks; clean and
status reuse formatSlotSize; leaving a store reuses
removeSharedStorePointer; withStoreLock is imported from its own module
instead of a re-export.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address review findings in the shared store (#3352)

- Never publish a graph whose build saw dirty files, and never trust a
  local-index seed on the up-to-date path; it may hold reverted edits.
- Record slot pointers and reclaim under the publish lock, and reclaim
  right after each publish, so a commit graph is never deleted between
  publish and pointer save and superseded graphs don't pile up.
- clean --gc decides membership from the registry, so opted-in clones
  and a main checkout without worktrees are not dropped.
- Leaving a store re-registers first, so an up-to-date run cannot leave
  the registry pointing at a deleted slot.
- Drop pinned branch summaries when an entry moves into a store slot.
- Keep run.cjs and the AGENTS.md runner path inside the checkout.
- MCP handles follow the slot's current graph, and branch scoping reads
  the slot's own metadata.
- Cache resolveGraphPath by metadata file identity; look up opted-in
  entries with canonical registry paths.

* fix(cli): localize help for the shared-store flags (#3352)

--help renders option text from the i18n catalog, so --share-with,
--no-share, clean --gc and clean --local-index need keys in both
locales, not just index.ts literals.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): lock the embed-job graph copy and skip it on forced rebuilds (#3352)

The server embed job copies a shared checkout's graph under the slot's
index lock, so a CLI analyze in another process cannot interleave. A
forced rebuild with no embeddings to carry over drops the pointer
without copying a graph it would discard unread.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): keep shared-store file reads inside checked paths (#3374)

Address CodeQL js/path-injection and js/file-system-race on
shared-store.ts: every filesystem read rebuilds its path under a fixed
parent with an inline path.relative barrier, the .git probe is one read
(EISDIR marks a directory) instead of stat-then-read, and the graph
pointer cache stats and reads through one file descriptor.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address review feedback on the shared store (#3374)

- Hold the slot index lock for the whole server embedding job, not
  just the graph copy.
- --no-share re-registers and deletes the old slot under that slot's
  index lock, so a running shared analyze cannot re-register it.
- clean --gc previews without --force, like every other destructive arm.
- status reports a pinned branch index as private.
- Slot names prefix Windows device names that carry an extension.
- A slot or store named ..<name> is a legal direct child.
- Shared-store suites run in the serialized lbug-db vitest project and
  clear an inherited GITNEXUS_SHARED_STORE.
- Doc and test accuracy fixes.

* test(storage): pin shared-store behavior for worktrees of a bare repository (#3374)

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address second review round on the shared store (#3374)

- Reject --no-share in a linked worktree before taking any lock or
  indexing anything.
- clean --all and remove also delete each shared checkout's pointer.
- Delete an empty store only while also holding its cache lock, and
  re-check emptiness under it.
- A store pointer is trusted only when the slot's own metadata names
  this checkout; the editable pointer file just says where to look.
- Device names with an extension are prefixed on Windows only, so POSIX
  slot names stay stable.
- Test fixtures use the gitnexus-test- prefix the stale-sidecar sweep
  recognizes; help text and the private-graph label are accurate.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address third review round on the shared store (#3374)

- clean --gc never collects a slot whose index lock is held: an analyze
  holds it until it registers the checkout, so a seeded but not yet
  registered slot is busy, not orphaned.
- Reclaim compares absolute paths, so a relative GITNEXUS_HOME does not
  make live commit graphs look unreferenced.
- graphPath is followed only into a published <commit>-<featureKey>
  dir, never .publish-* staging (TS and all three hook copies).
- clean --gc fails on an unreadable stores root instead of reporting
  nothing to collect.
- --no-share help states it is for opted-in clones.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(cli): land the English --no-share help and private-graph label (#3374)

These two strings were meant for e2a9467 and d746675 but were left out
of the commit; the zh-CN side landed.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address fifth review round on the shared store (#3374)

- analyze --no-share leaves the shared store even when routed to a
  branch sub-index (gate on sharedStore, not placement.branch)
- clean --gc aborts a store whose member listing is unreadable instead
  of treating it as empty, and skips non-directory entries under stores/
- reusing an existing commit graph no longer fails a finished analyze
  when the redundant private graph cannot be wiped
- a store pointer holding JSON null, a number, a string, or an array is
  treated as invalid
- clean, remove, and DELETE /api/repo hold the checkout slot's index
  lock while deleting the slot
- the server analyze launcher waits on the checkout slot the worker
  actually writes
- sync the Factory hook copy; isolate hook tests from storage overrides;
  use a junction for the Windows worktree alias; the relative
  GITNEXUS_HOME test now sets a relative home

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address sixth review round on the shared store (#3374)

- clean, remove, and analyze --no-share remove the checkout's store
  pointer while still holding the slot's index lock, so an analyze that
  takes the lock next cannot have its new pointer deleted
- clean --gc does not follow a symlink under stores/ (lstat)
- removing a store pointer keeps the checkout's .gitnexus directory when
  it cannot be listed, instead of treating it as empty

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address seventh review round on the shared store (#3374)

- clean --gc aborts when the registry cannot be read instead of treating
  every member as orphaned; with no registry file it collects only
  members whose checkout directory is gone
- seeding from a repository-local index re-reads its metadata under the
  index lock, so the copied graph and the saved metadata match
- clean --gc skips a store another collector removed meanwhile, and
  reports "no shared stores" when stores/ holds only stray files

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address eighth review round on the shared store (#3374)

- removing a checkout's storage unregisters it and removes its store
  pointer before deleting the slot directory, which the file lock
  backend uses for its lock file; withCheckoutSlotLock becomes
  removeCheckoutStorage, used by remove, clean, and DELETE /api/repo,
  and analyze --no-share follows the same order
- the clean --gc preview skips a slot whose index lock is held, matching
  what --force would drop

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* feat(storage): share the index store between clones automatically (#3352)

Clones of one repository now share like linked worktrees. A clone whose
normalized origin URL matches another registered, still-present clone
joins that clone's store, or founds one (keyed on its own path) that the
sibling joins on its next analyze. A lone clone keeps its own .gitnexus.
Graphs stay keyed by commit and feature key, so clones only ever share a
graph built from the same commit with the same settings.

`analyze --no-share` now records a lasting opt-out (`shareOptOut` on the
registry entry, preserved across re-registration); `--share-with` clears
it. The analyze worker reports the storage it wrote over IPC so the
server settles a clone's first shared slot.

A query-time base-plus-overlay graph stays out: LadybugDB reads one
database per query. Instead, private graph copies record whether the
filesystem cloned them copy-on-write (sharing unchanged pages on disk)
or made a full copy, and `status` reports it.

* fix(storage): never follow a symlinked checkout .gitnexus (#3374)

A checkout whose `.gitnexus` is a symlink (e.g. `.gitnexus -> ..`) made
the shared-store pointer helpers operate on whatever it pointed at:
findLegacyLocalIndex listed the target as a "legacy index", so
`clean --local-index --force` recursively deleted the checkout's
siblings; writeSharedStorePointer wrote store.json/.gitignore there; and
removeSharedStorePointer deleted store.json there and could rm -r the
target directory.

All four now go through probePointerDir, which lstats `.gitnexus` and
accepts it only when it is a real directory whose realpath is
realpath(checkout)/.gitnexus (mirroring stale-branch-slots.ts). Anything
else is left untouched: no legacy index is reported or removed, and no
pointer is written or removed. removeLegacyLocalIndex re-probes after
sizing, just before its delete loop.

* fix(storage): never share a graph from a checkout that hides files (#3374)

Trigger: a sparse checkout, a skip-worktree/assume-unchanged entry, or an
uninitialized submodule leaves `git status` clean, and the run's
indexCoverage.dirtyPaths drops paths with no file hash, so publishSharedGraph
published a graph missing those files as the commit graph. seedSharedSlot
then copied the seed's lastCommit into the new pointer slot, so the next
analyze of a sibling hit the up-to-date fast path without hashing.

Fix: add isWorkingTreePristine (storage/git.ts): the unfiltered
listWorkingTreeDirtyPaths must be empty (null fails closed) and every
gitlink in the index must have a checked-out `.git`. publishSharedGraph
requires it instead of isWorkingTreeDirty. seedSharedSlot keeps the seed's
lastCommit only when the seed is at HEAD and the checkout is pristine, so a
clean sibling still fast-paths onto the shared graph; any other seeded
pointer gets an empty lastCommit, like seedFromLocalIndex, and its next run
hash-diffs, then re-points at the commit graph on publish.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): keep graphs with pending embeddings out of the shared store (#3374)

Trigger: an analyze that finished with embeddings still owed (meta carries
embeddingCheckpoint) was published as the commit graph, because the
feature key ignores the checkpoint and publish never checked it. The
published meta kept the checkpoint while the graph could never change. The
next run healed the embeddings privately, found the commit graph already
there, wiped its own healed graph and pointed back at the partial one.

Fix: publishSharedGraph treats a checkpointed graph as not shareable, so it
stays private and no published commit graph carries a checkpoint. When the
target commit graph exists but records a checkpoint, has fewer
stats.embeddings than the private graph, or has unreadable metadata, the
checkout keeps its private graph instead of re-pointing. The commit graph
is left as is because other checkouts may read it. Embeddings sync and the
server embed job already privatize a pointer slot before writing
(ensurePrivateSharedGraph).

* fix(storage): rebuild a shared slot whose graph is missing (#3374)

A publish interrupted between moving the checkout's graph into
`.publish-<uuid>` staging and renaming staging onto the commit dir left
slot metadata at HEAD with no graph and no graphPath; the next reclaim
deleted the orphaned staging. The up-to-date fast path never checked that
the graph exists, so every later analyze reported "Already up to date"
over a checkout with no index. A failed restore in publishSharedGraph's
catch had the same outcome, and also deleted the staging dir holding the
only copy of the graph.

- run-analyze: for a shared-store slot, stat the graph the checkout reads
  (resolveGraphPath for the flat slot, the branch slot's own lbug
  otherwise) before the fast path; if it is missing, force a full
  rebuild. An incremental run would diff nothing into a fresh, empty
  database. Private .gitnexus indexes are unchanged: they only lose their
  graph by hand, and metadata-only fast-path fixtures rely on that path.
- publishSharedGraph: when moving the staged graph back fails and it is
  still in staging, keep the staging dir, log its path, and skip this
  run's reclaim, which would otherwise delete it. The next analyze finds
  no graph and rebuilds.

* fix(storage): fail safe on unreadable slot metadata during reclaim (#3374)

Trigger: reclaim counted commit-graph references with loadMeta, which
returns null for a torn or unreadable gitnexus.json as well as for a
missing one. A member whose metadata could not be read therefore
"referenced nothing", and the graph it still used was deleted. Separately,
in `clean --gc` an orphan slot that fs.rm could not delete threw out of
reclaim, aborting the collection of every store after it.

Fix: the reference loop reads slot metadata with a local loadMetaStrict.
Only absent metadata (ENOENT/ENOTDIR, same legacy-mirror fallback as
loadMeta) means no reference; any other read error or a parse failure
throws with the file path, like listDirStrict. Every caller already
treats a reclaim throw as best effort (analyze logs "skipped cleanup",
slot removal ignores it) or surfaces it (clean --gc). A failed orphan
slot delete is now kept: it stays a member, so the graph it names is
kept too, and it is reported in ReclaimResult.keptMembers and by a new
clean --gc line. loadMeta itself is unchanged.

* fix(server): unregister under the slot lock and answer 409 on DELETE /api/repo (#3374)

DELETE /api/repo called removeCheckoutStorage(storagePath) with no
unregister callback and no checkout path, swallowed every error, and
unregistered later outside the slot lock. For a shared-store slot this
left the checkout's store.json pointer behind, let an analyze re-register
between the slot removal and the unregister, and reported {deleted} even
when the slot lock could not be taken because an analyze held it.

The handler now calls removeCheckoutStorage(storagePath,
() => unregisterRepo(entry.path), entry.path), matching `gitnexus remove`
and `gitnexus clean`, so the unregister and the pointer removal run under
the slot lock; non-shared storage is still removed, then unregistered.
The later standalone unregister is gone. An IndexLockTimeoutError answers
409 and leaves the entry registered; any other failure propagates to the
handler's 500, also with the entry kept so the delete can be retried,
instead of unregistering over leftover index files.

* fix(storage): give concurrent sibling clones one deterministic founder key (#3374)

Trigger: two registered clones of one origin, both still on local storage,
analyzing at the same time each saw no sibling store yet and founded a store
keyed on their own checkout path. registeredStore() then kept each clone in
its own store for good, so they never shared a graph.

Fix: when no sibling store exists, siblingCloneStore keys the new store on
the canonical path that sorts first among this clone and its registered
siblings (case-folded on Windows, like registryPathEquals), so every sibling
computes the same key. An existing sibling store still wins. Clones that
already diverged into two stores are not migrated.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): keep subdirectories of a clone out of shared stores (#3374)

Trigger: `analyze --skip-git <clone>/pkg` inside a clone with a registered
sibling of the same origin joined, or founded, a clone store. getRemoteUrl
answers from any subdirectory, so siblingCloneStore saw the enclosing
clone's remote. That broke the shared-store invariant that only tree roots
participate.

Fix: resolveOptedInStore now returns undefined for a path with no `.git`
entry. It uses hasGitDir, which accepts a directory or a linked-worktree
file, the same as resolveSharedStore's readCommonDir gate and run-analyze's
repoHasGit. `--share-with` from such a path throws a clear error.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(hooks): prefix Windows device names with an extension in hook slot names (#3374)

Trigger: on Windows, storage-slot.ts sanitizeSlotBasename prefixes a
device-name basename that has an extension (`CON.txt` -> `repository-CON.txt`),
but the hook's copy in registry-query.cjs only matched the bare device name.
With GITNEXUS_STORAGE_ROOT set, a checkout named e.g. `con.txt` got a
different slot from the hook than from the CLI, so the hook could not see its
index.

Fix: mirror the platform branch (extension form on win32, bare form
elsewhere) in all four byte-identical registry-query.cjs copies, and point
their header comments at storage-slot.ts. Add a hook-vs-TS parity test over
device-name basenames on both stubbed platforms, and fix the byte-identity
test title to say four copies.

* refactor(storage): tidy the shared-store fix series (#3374)

Explain the keptStaging early return where it is checked, reuse the
exported EmbeddingCheckpoint type in the publish test, and drop
review-step labels from test comments. No behavior change.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(storage): address ninth review round on the shared store (#3374)

- removeCheckoutStorage: keep the lock-safe order (unregister and drop the
  pointer under the slot lock, delete the slot last), but when the final
  rm fails, throw an error that says the checkout was already unregistered,
  names the leftover slot, and points at `gitnexus clean --gc --force`.
- clean --gc preview no longer sweeps staging files: acquireIndexLock
  takes `sweep: false`, which the dry-run reclaim passes.
- listStoreMetaRoots reports completeness; a store directory that cannot
  be listed (other than missing) makes the parse-cache prune retain every
  chunk instead of evicting keys other members still use.
- clean.shared.kept says "could not be removed" rather than "still open".
- ARCHITECTURE.md describes the stores/<key>/ layout and store.json
  pointer; README lists every GITNEXUS_SHARED_STORE off value and that it
  also stops clone sharing.
- Tests: close the direct Ladybug connection in finally; fix a fixture
  JSDoc.

* test(storage): pin the publish gate for cone and sparse-index checkouts (#3374)

isWorkingTreePristine already rejects every sparse mode, because each one
marks left-out entries skip-worktree and `git ls-files -v` expands a sparse
index. Only no-cone was tested; cover cone and cone with a sparse index too.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* docs(storage): name the checks that answer recurring review findings (#3374)

Comment-only. The review bot re-derives findings from the code on every
push, so put the refuting fact next to each flagged line: the pristine
check's hidden-path coverage, sparse checkouts being skip-worktree, the
lock-safe unregister-then-delete order, the hook parity test for device
names, and why the stores/ lstat is not a race guard.

* feat(setup): add Factory Droid (MCP + skills) to gitnexus setup

Register 'droid' in the editor-targets abstraction so `gitnexus setup -c droid`
writes the MCP server to ~/.factory/mcp.json and installs skills to
~/.factory/skills/ from the single canonical skills/ source (no per-editor
copies). uninstall.ts is target-driven, so removal is covered automatically.
Adds unit + round-trip coverage.

* feat(plugin): add gitnexus-factory-plugin for droid plugin install

* docs: add Factory Droid to editor support table and setup docs

* fix(factory-plugin): guard augment hook against fan-out and DB contention

Reuse the Claude adapter's acquireHookSlot and LadybugDB owner probe
(bundled byte-identical, kept in lockstep by a drift test) instead of
running an unguarded augment. Add direct tests for the hook and manifests.

* docs: align Factory row in editor support table

* fix(factory-plugin): honor GITNEXUS_HOOK_CLI_PATH so augment runs on Windows

* docs(hooks): point bundled guard copies at their drift tests

* docs(factory-plugin): note the Execute tokenizer's quoting limit

* docs(readme): clarify the Full tier and group the Factory row

* docs(hooks): trim drift note to a single line

* test(ci): run factory-plugin tests on the windows cross-platform lane

* refactor(hooks): drop the drift-note comments, the tests already enforce it

* fix(factory-plugin): pin CLI version and parse quoted shell patterns

- Pin mcp.json and the hook's npx fallback to gitnexus@<version> from
  the plugin manifest, registered with the release sync script so a
  mutable @latest can never execute on MCP connect or augment fallback
- Port the #2938 shell tokenizer (tokenizeShellWords + parseRgGrepPattern)
  so quoted, backslash-escaped, --regexp=, -eVALUE, and -- patterns survive
- Add the #2938 regression matrix and pin assertions to factory-plugin.test.ts

* docs: add Factory Droid to published npm README

* fix(factory-plugin): wire marketplace so droid installs the Factory plugin

Add .factory-plugin/marketplace.json sourcing ./gitnexus-factory-plugin.
Droid reads it before .claude-plugin/marketplace.json, so
`droid plugin install` now delivers the Factory plugin (Execute matcher,
pinned mcp.json) instead of the translated Claude plugin (Bash matcher,
gitnexus@latest). Register the surface in the version-sync script and
cover the wiring in the factory and sync test suites.

* fix(factory-plugin): use registry lookup for index resolution

Bundle registry-query.cjs so external indexes resolve (#3060); re-pin to 1.6.12.

* fix(factory-plugin): sync Execute parser with Cursor hook

Fixes echo-rg and -f false positives; tighten test env isolation.

* fix(factory-plugin): stop no-match augment from re-running via npx

A PATH `gitnexus` that finds no match exits 0 with empty stderr, which
fell through to a second `npx -y gitnexus@<pin> augment` with its own 8s
timeout (16s worst case vs the 10s hook budget). Fall through to npx only
when the PATH launcher is missing (ENOENT); any launched PATH binary,
including a timeout or non-zero exit, now ends the augment.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(factory-plugin): filter augment stderr to the [GitNexus] block

runAugment returned raw child stderr, so npm/Node/LadybugDB warnings leaked
into additionalContext and noise-only stderr counted as success. Port the
Claude adapter's extractAugmentContext (verbatim, with isDebugEnabled) and
apply it on every launch tier before the success decision. Adds a drift test
against the Claude copy and PATH-tier noise/noise-only behavior tests.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(factory-plugin): quote DROID_PLUGIN_ROOT in hook command

An unquoted plugin root containing spaces (e.g. a Windows user profile
path) split into multiple argv words, so the PostToolUse hook silently
never ran. Quote it like the Claude plugin does, and pin the exact
quoted command in the hooks.json wiring test.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(release): stage Factory plugin manifests in the release commit

The rc release job stages only the original four manifest surfaces in the
detached release commit, so the v<version> tag tree carried the Factory
plugin.json, mcp.json and marketplace.json at the previous version while
--check (working tree) passed. Stage them too, and guard the git add block
against the synced surfaces in sync-plugin-manifests.test.ts.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* refactor(factory-plugin): simplify hook gates, spawn tiers and tests

- main(): resolve the repo only after the tool-name and pattern gates,
  matching the Claude/Cursor hook order (skips fs/git work on no-op calls).
- runAugment(): share one spawnAugment helper between the
  GITNEXUS_HOOK_CLI_PATH and npx tiers; PATH tier ENOENT logic unchanged.
- factory-plugin test: pre-filter comment lines instead of `continue`.
- sync-plugin-manifests test: hoist EXECUTABLE_MCP_FILES and derive
  TOTAL_SURFACES from its length.
- fnSource(): throw when the function or its closing brace is not found.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(cli): list Factory Droid in localized setup help

`localizeCliHelp` overwrites the `setup` command description with the
`help.command.setup.description` i18n key, so the literal edited in
index.ts never reached `gitnexus setup --help`. Add Factory Droid to the
en and zh-CN keys.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Address PR review feedback (#2543)

- factory hook: run every augment tier under the bundled Unix timeout
  guard (npx tier group-kills), keeping exactly-one-tier fall-through
- hook-db-lock-probe: trim GITNEXUS_HOOK_{LSOF,PS}_PATH once so a padded
  override is used, not silently replaced (all 3 copies)
- hook-lock: evict a stale slot via rename-to-tombstone + identity check,
  so a concurrently recreated fresh lock is never deleted (all 4 copies)
- registry-query: a set-but-invalid storage override resolves no repo
  instead of falling back to the registry storagePath (all 4 copies)
- publish.yml: stage the ten skill mcp.json manifests in the rc release
  commit; the staging test now requires every synced surface

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Address PR review feedback round 2 (#2543)

- hook-lock: replace rename-to-tombstone eviction with an O_EXCL per-slot
  `.evicting` marker plus an identity re-check before unlink, so a live
  lock is never moved, and a crashed evictor leaves only a self-expiring
  marker (all 4 copies)
- hook-db-lock-probe: clamp GITNEXUS_HOOK_PROC_CMDLINE_MAX to a named
  256 KiB ceiling and require an integer, so an oversized override can
  no longer fail the buffer allocation and miss a live owner (all 3 copies)
- registry-query: treat an empty GITNEXUS_STORAGE_PATH/ROOT as set but
  invalid, matching the CLI's `!== undefined` rule (all 4 copies); the
  factory test env now deletes those keys instead of blanking them

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Address PR review feedback round 3 (#2543)

- hook-db-lock-probe: a capped /proc cmdline read stops early only once
  both the GitNexus token and the mcp/serve mode are present (or at EOF,
  the ceiling, or the budget), so a mode word such as `--require mcp`
  before the GitNexus path no longer hides a live owner (all 3 copies)
- registry-query: correct the override comment; a filesystem root is
  invalid only for GITNEXUS_STORAGE_PATH, not GITNEXUS_STORAGE_ROOT
  (all 4 copies, comment only)

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Address PR review feedback round 4 (#2543)

- hook-db-lock-probe: an fd-directory read error other than ENOENT or
  ENOTDIR on an identified server candidate now fails closed ('timeout')
  instead of reporting not-owned (EMFILE/ENFILE/ENOMEM/EINTR)
- hook-db-lock-probe: resolve GITNEXUS_HOOK_TIMEOUT_PATH to an absolute
  path before validating and caching it, so callers that spawn with a
  request cwd can still execute the guard
- hook-db-lock-probe: document the chunked cmdline read's actual stop
  conditions (all 3 copies)

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Harden hook-lock eviction marker lifecycle (#2543)

Per the chosen option (B) for the stale-slot eviction race:
- `.evicting` markers carry a per-call owner token (pid + random hex)
- an evictor re-reads its token immediately before the slot identity
  check and unlink; a stalled evictor whose marker was broken backs off
- `finally` removes the marker only while it still holds our token
- an orphaned marker is broken only if, re-checked just before unlink,
  its bigint identity and token are unchanged from when judged stale
- doc comment states the two remaining two-syscall windows (slot
  lstat->unlink, marker token->unlink); POSIX has no conditional
  unlink, and the worst case is one extra concurrent augment

All four byte-identical hook-lock copies updated.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Fix CodeQL file-system race in hook-lock orphan-marker check (#2543)

breakOrphanedMarker stat'd the marker by path and then read it by path,
which CodeQL flags (js/file-system-race): the file could be replaced
between the two calls. Take the stat and the token from one open
descriptor (readMarkerSnapshot, O_NOFOLLOW where available) for both the
"judged stale" snapshot and the pre-unlink re-check. All four hook-lock
copies updated.

The replaced-marker test injected its swap via a readFileSync(path) spy,
which no longer fires; it now swaps the marker just before its second
open, counting opens of the marker path only (a per-path counter fired
early on slot-0 and let a mutant pass).

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Unregister hook-lock exit listener on release (#2543)

Each acquireHookSlot registered `release` as a process 'exit' listener
that was never removed, so a long-lived process acquiring and releasing
slots repeatedly would accumulate listeners (MaxListenersExceededWarning)
and retain every closure. release() now removes itself. All four
hook-lock copies updated; a test asserts 12 acquire/release cycles leave
the 'exit' listener count unchanged.

* test(cli): parse TypeScript with a TypeScript 6 API package

Keep AST guards working after the named typescript package becomes 7, which no longer ships the Compiler API.

Co-authored-by: Cursor <cursoragent@cursor.com>

* chore(lint): pin root TypeScript to the 6 API package

Give typescript-eslint a TypeScript 6 peer so syntax-only lint still installs after CLI and web move to TypeScript 7.

Co-authored-by: Cursor <cursoragent@cursor.com>

* chore(deps): compile first-party packages with TypeScript 7.0.2

Unify CLI and web on the same native compiler line as gitnexus-shared so typecheck and emit no longer split 5.x versus 7.x.

Co-authored-by: Cursor <cursoragent@cursor.com>

* docs(ci): describe parent TypeScript 7 as the shared compiler

Stop saying web compiles shared with TypeScript 5 now that the parent lockfile is 7.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(ci): compile shared from parent TypeScript on Vercel and skill-evolution

Stop isolated npm installs in gitnexus-shared so those paths do not pull a second TypeScript 7 optional-platform tree.

Co-authored-by: Cursor <cursoragent@cursor.com>

* docs: record TypeScript 7 typecheck and Dependabot major-split policy

Keep contributor typecheck commands, and stop Dependabot from bumping shared onto a different TypeScript major than CLI and web.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(lint): pin root TypeScript to 5.9 so npm ci satisfies eslint peers

typescript-eslint 8 peers typescript below 6.0.0, so the typescript6 alias made quality lint npm ci fail with ERESOLVE.

Co-authored-by: Cursor <cursoragent@cursor.com>

* test(cli): drop the TypeScript 6 Compiler API package

TypeScript 7.0 has no classic createProgram surface, so parse-only
guards now use Babel and Mode 4 uses the TypeScript 7 Checker.

Co-authored-by: Cursor <cursoragent@cursor.com>

Stop telling clones to npm-install gitnexus-shared; CI and Vercel already emit that package from a parent lib/tsc.js shim.

* fix(web): typecheck React JSX on TypeScript 7 with explicit DOM libs

TypeScript 7 no longer implies DOM or auto-includes @types, so the web app must declare React/JSX settings while Vite keeps plugin-react.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(embeddings): isolate local ONNX inference in a child_process sidecar

The analyze parent must not load onnxruntime-node. Fork a sidecar for
vectors only and reap it on worker exit; keep Ladybug writes in-process.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(embeddings): share the sidecar client across MCP, serve, and sync

Query hosts now use the core façade instead of a second in-process ONNX
embedder. Search skips an empty table, sync reaps beside closeLbug, and
ready means the stack is resolvable rather than a warm singleton.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(embeddings): refuse Intel Mac and unloadable prefix before npm heal

Analyze, sync, install, and the sidecar client now consult the platform
blocker before forking or downloading the optional stack. HTTP stays the
escape hatch; wasm is not treated as a rescue.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(embeddings): take the ONNX stack off default npm install

Pins live in gitnexusEmbeddingStack. embeddings install writes prefix
overrides before npm spawn. Leftover 1.6.12 package-first trees are residual.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(publish): drop grammar source from the published tarball

Every vendored grammar has 6/6 prebuilds, so files ships those plus
Leiden and FTS instead of parser.c. First ship stays above 80 MiB.

* test(embeddings): match MCP missing-stack warn to the R20 copy

Default install no longer calls the stack optional, so the once-per-backend

* fix(review): bound sidecar death, cancel writes, and publish-file guards

Init-time native crashes no longer respawn a child on every query. Local
embedBatch honors AbortSignal after sidecar return, MCP query() surfaces
vector-lane degradation, disconnect always reaps, and the grammar prepack
guard checks files globs instead of on-disk prebuilds.

* refactor(embeddings): share runtime preflight and sidecar reap helpers

* Fix macOS hook test expecting realpath'd registry paths.

resolveHookRepo returns the written registry path, not a filesystem realpath, so the assertion must match that.

* Address gitnexus-check warnings on hook install docs and slot tests.

The Cursor troubleshooting list omitted registry-query.cjs, and the writable-slot test only checked that isDirectory exists instead of that the path is a directory.

* Align the HTTP catalog source-scan with skippable resolveRepo validation.

resolveRepo lists fresh repos with validate: options.validateStorage !== false so DELETE can skip prune; the test still required a literal validate: true.

* Harden storage path sinks so CodeQL path-injection and ReDoS alerts clear.

Contain every filesystem probe inside the resolved storage slot with the inline path.relative idiom, reject filesystem-root slots, and trim slot basenames in linear time.

* Settle bridge stamps before writing so CI size/mtime matches stay stable.

LadybugDB can still flush into bridge.lbug after close+rename; persist whole-millisecond mtimes and wait for consecutive stats to agree so a freshly written pair matches.

* Type the settled bridge stat as fs.Stats so tsc does not see bigint.

Awaited<ReturnType<typeof fsp.stat>> collapsed the bigint overload and broke prepare/typecheck on CI.

* Keep the bridge mtime stamp exact so same-size swaps still fail the pair check.

fix(review): fail closed on foreign embedding identity and vector-width drift (#3260)
Applied from a ce-code-review pass over this branch (run 20260911-053832-b49f88d6).

- `embeddings sync` now gates EVERY checkpoint kind on embedding identity.
  `unverified-count` was exempted, but `decideEmbeddingResume` abandons that
  kind before it compares identity, so the exemption was the only thing
  keeping a foreign model from filling holes beside the old model's vectors —
  two vector spaces in one CodeEmbedding table, reported healthy. The test
  that asserted this run succeeds now asserts the refusal.

- `embeddings sync` refuses when the index's recorded vector width differs
  from this run's. The column is FLOAT[N] fixed at build time and the pipeline
  deletes each batch's stale rows immediately before inserting, so a width
  change deleted rows it could not re-insert. `analyze` already forces a
  rebuild on the same mismatch; only a rebuild can retype the column.

- `GITNEXUS_EMBEDDING_RETRY_TIMEOUTS` parses with the repo's truthy convention
  (`1`/`true`/`yes`). The integer parser threw on `true`, so the conventional
  spelling hard-failed every embedding call rather than enabling the flag or
  leaving it off. README names the accepted spellings.

- One `persistMeta` write path replaces three inlined metadata
  read-modify-writes; #2790 traced two production drifts to hand-copied
  writers of these exact fields.

- Tests: the pipeline mock now invokes `onCheckpointWindowStart`/`onCheckpoint`,
  so the resume contract actually executes under test. Added coverage for the
  incomplete-index refusal, the partial-checkpoint branch, and the body-read
  timeout retry site that the existing opt-in test never reached.

Verified: tsc --noEmit clean; 99 tests pass across the three affected suites;
prettier clean.

* Make long HTTP embedding jobs resumable

Retry endpoint timeouts when explicitly configured, creating a fresh abort signal for every attempt. Add gitnexus embeddings to fill an existing index in place: every successful batch is durable, and rerunning skips vectors whose content hash still matches instead of rebuilding the structural graph.

* Address PR review feedback (#3065)

Hold the per-index lock around embeddings sync, fail closed on a foreign-identity partial checkpoint, and refuse to create an empty DB from leftover metadata. Use the canonical embedding count, keep closeLbug from masking the real error, load hashes instead of full vectors, and document GITNEXUS_EMBEDDING_RETRY_TIMEOUTS.

feat: add Zig language support (#1432)
* feat: add Zig language support

Adds a Zig LanguageProvider grounded in @tree-sitter-grammars/tree-sitter-zig 1.1.2.
The grammar's published peerOptional `tree-sitter@^0.22.1` is suppressed via an
npm `overrides` entry that aliases the peer to the bundled `tree-sitter@0.21.x`;
load-time smoke testing confirmed ABI compatibility.

v1 capabilities:
  - .zig file detection + Prism syntax mapping
  - Top-level + nested function_declaration as Function/Method
  - struct/enum/union (anonymous in the grammar — owner name resolved from the
    enclosing variable_declaration in class/field/method extractors)
  - container_field as struct/union fields and enum variants
  - top-level const/var as Variable nodes
  - free + member call_expression as @call edges
  - @import("./foo.zig") local-file resolution; std and external packages
    return empty (no ghost edges)
  - pub keyword detection for export checking
  - no heritage hooks (Zig has no inheritance; queries never emit @heritage.*)

Generic extractor changes (backward-compatible):
  - field-extractors/generic.ts and method-extractors/generic.ts: empty
    `bodyNodeTypes` falls back to the type declaration node itself as its own
    body container — needed because Zig's struct_declaration directly contains
    its container_field children. (The `extractOwnerName` hook this commit
    originally introduced now exists upstream; Zig just configures it.)

Out of scope (deferred):
  - usingnamespace, build.zig.zon package graph, comptime/anytype
  - scope-resolution hooks (emitScopeCaptures, interpretImport, …): Zig is
    classified `experimental` and uses the generic fallback resolution path
  - cross-package imports (std, deps)

Tests:
  - new fixture test/fixtures/sample-code/simple.zig
  - Zig describe block in tree-sitter-languages integration test
  - simple.zig added to parsing.test.ts fixture-existence list
  - Zig added to ingestion-utils detection unit test
  - Zig smoke case in parser-loader-abi.test.ts
  - Zig grammar registered in the grammar-literal validation gate

* feat(zig): integrate build.zig.zon resolution + Union label from PR 1096

Ports the additive pieces of grgisme's standalone Zig provider PR
(https://github.com/abhigyanpatwari/GitNexus/pull/1096) onto the rebased
provider:

  - build.zig.zon `.path` dependency resolution for bare-name
    @import("pkg") (parseZigBuildZon / loadZigBuildZon in
    language-config.ts, resolveZigImportInternal in import-resolvers/zig.ts,
    wired through ImportConfigs.zigBuildZon). `.url` deps and
    repo-escaping paths return null cleanly. 13 unit tests.
  - `union(enum)` containers now produce `Union` nodes (not Struct):
    'Union' added to ClassLikeNodeLabel + CLASS_LIKE_LABELS, the Zig query
    tags @definition.union, CONTAINER_TYPE_TO_LABEL maps union_declaration
    to 'Union'. The label was already plumbed graph-wide on main.
  - /^build$/ entry-point pattern (build.zig).
  - zig-basic lang-resolution fixture + resolvers integration test.

Adapted to current main while porting:

  - labelOverride relabels container-nested fns Function → Method
    (mirrors isKotlinClassMethod); the structure phase no longer derives
    Method from the legacy method-extraction path for plain
    @definition.function captures.
  - IMPORTS/CALLS edges require scope-resolution hooks
    (emitScopeCaptures / interpretImport) since the legacy DAG removal;
    Zig does not implement them yet, so the integration test documents
    that with a skipped import-edge case. The resolver itself is wired
    into the resolver factory and becomes live when the hooks land.

Not ported: named-bindings extractor (the legacy namedBindingExtractor
API no longer exists) and the bespoke field extractor (the generic
factory's extractOwnerName / empty-bodyNodeTypes hooks cover Zig).

* feat(zig): scope-resolution hooks — IMPORTS and CALLS edges (Ring 3)

Implements the registry-primary scope-resolution path for Zig, the
prerequisite for cross-file edges since the legacy DAG removal. Adds the
standard per-language stack under languages/zig/:

  - query.ts: scope query (containers as Class scopes, blocks, functions),
    declarations (container anchors placed on the container node itself so
    the def lands in its own Class scope and the name binding auto-hoists
    to the parent — populateClassOwnedMembers needs the class-like def
    among the class scope's ownedDefs), @import statements (#eq?-gated
    builtin), parameter/constructor type bindings, and call/constructor
    reference sites. The grammar is required lazily (optionalDependency).
  - captures.ts: emitZigScopeCaptures — groups query matches, drops the
    plain-variable group for container/import bindings (their dedicated
    rules bind the name), and relabels container-nested fns
    @declaration.function → @declaration.method (labelOverride parity).
  - interpret.ts: namespace-kind imports (const x = @import("…")) and
    type bindings — self-parameter convention marks the receiver, Zig
    sigils (*, ?, [], error unions, const) stripped from type names while
    dotted qualifiers (mod.T) are preserved for Case-3 namespace-prefix
    receiver dispatch.
  - simple-hooks.ts: parameter bindings stay function-local (Go
    rationale), local-over-import merge precedence, bounds-check arity
    (always 'unknown' today — no synthesized arity metadata).
  - scope-resolver.ts: emit-side wiring; build.zig.zon threads through
    loadResolutionConfig into the same resolveZigImportInternal the legacy
    resolver config wraps. fieldFallbackOnMethodLookup off (statically
    typed). Registered in SCOPE_RESOLVERS.

The resolvers integration test un-skips the import-edge case and gains
CALLS assertions: free call (main → helper) and receiver-bound method
dispatch through a namespace-qualified constructor
(var p = pioneer.Pioneer{…}; p.tick() → main → tick).

* fix(zig): Union is class-like + missing-grammar warning (review pass)

Self-review findings on the Zig branch:

  - scope/walkers.ts `isClassLike` and finalize-algorithm's
    CALLABLE_OR_TYPE_LIKE did not include 'Union': a `union(enum)`
    container's methods got no ownerId from populateClassOwnedMembers, so
    method dispatch on union receivers silently dropped. Widened both
    sets; the zig-basic fixture gains a Tag method + a CALLS assertion
    (main → isEnergy) that fails without the widening (verified by
    reverting).
  - optional-grammars.ts now lists tree-sitter-zig with an npm `probe`
    (it is an optionalDependency, not vendored): users with .zig files
    and no prebuild get the standard one-line stderr warning instead of
    a silently degraded index.
  - Deduplicated the container-method predicate: `isZigContainerMethod`
    + ZIG_CONTAINER_TYPES now live once in languages/zig/captures.ts and
    feed both the provider labelOverride and the scope-capture relabel.
  - README language matrices: Zig row now claims Type Annotations,
    Constructor Inference, and Config (build.zig.zon) — all true since
    the scope-resolution hooks landed.

* fix(zig): anchor @declaration.variable to the binding identifier

`(variable_declaration (identifier) @declaration.name)` matched EVERY
identifier child of the node, so `const first = target;` also declared a
phantom local named `target` in the enclosing block. That phantom shadowed
the real function for later references (and starved callable-value-flow
seeds of a target). The `.` anchor pins the pattern to the first named
child — the bound name.

Regression test in resolvers/zig.test.ts pins the capture set.

* feat(zig): callable-value-flow captures + main's per-language conformance gates

Post-rebase catch-up: since this branch forked, main added three "every
registered language must appear here" tests. Each needs a Zig entry:

- callable-value-flow (#2522): Zig now emits `@callable-flow.*` facts via
  `synthesizeCallableFlowCaptures` (ZIG_CALLABLE_CAPTURE_OPTIONS in
  zig/captures.ts). tree-sitter-zig's `call_expression` carries arguments
  as direct children with no wrapper node, which the shared helper could
  not decompose, so this adds a language-neutral `extractCallArguments`
  hook (mirror of `extractFunctionParameters`; `undefined` = shared path).
  Zig joins the provider matrix as 'matrix' with a real assign→copy→
  argument→invoke case.
- external-import-conformance (#2953): `@import("std")` beside a decoy
  `src/std.zig` resolves to nothing; the decoy stays reachable via the
  relative spelling. Zig holds the property (no suffix fallback), so it is
  a case, not a KNOWN_GAPS entry.
- import-target-index-reuse contract (#2909): membership-probe-only
  fixture (minimumScans: 0, same shape as Rust).

* fix(zig): address gitnexus-check review findings

One commit per the bot's list so each item is easy to check off:

- parser-loader: Zig row gains `userSkippable: true`, so
  `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` (=1 or a list naming `zig`) disables it
  at analyze time like swift/dart/kotlin — as `optional-grammars.ts` already
  documented. Covered in parser-loader-skip-optional.test.ts.
- export-detection: `zigExportChecker` stops at the first declaration it
  reaches. A non-`pub` fn inside `pub const T = struct {…}` was reported
  exported because the walk continued up to the wrapper.
- import-resolvers/zig: a `.path = "."` dep normalizes to '' and no longer
  grows a leading slash (`/src/main.zig` could never match).
- language-config: build.zig.zon parsing strips `//` comments string-aware
  (a `//` inside `.url = "https://…"` survives) and matches braces while
  skipping string literals, so a commented-out `.path` cannot declare a dep
  and a `}` in a comment/string cannot truncate the block.
- method-extractors/configs/zig: the leading `self` receiver is excluded
  from `parameters` (Rust parity). Fixing that exposed a worse bug: the
  `parameters` node is a plain child of `function_declaration`, not a
  `parameters:` field, so `childForFieldName('parameters')` was always null
  and every Zig method had no parameters, no receiver and `isStatic: true`.
  One `zigParameterList` helper now feeds all three readers.
- variable-extractors/configs/zig: container (`struct`/`enum`/`union`) and
  `@import` bindings are skipped via the same predicate the scope captures
  use (`isZigContainerOrImportBinding`), instead of the comment merely
  claiming they were.
- tree-sitter-languages.test.ts: the "missing grammar" case now forces the
  absent-binding path through the loader's runtime opt-out on a fresh module
  instead of passing vacuously when the package is installed.

New: test/unit/zig-extractors.test.ts (exports, receiver/parameters,
variable guard); zig-import-resolver.test.ts gains the `.` dep, comment and
brace cases.

The `createFieldExtractor` heads-up needs no change: the added branch is
unreachable for every existing config (none has empty `bodyNodeTypes`).

* fix(zig): address second gitnexus-check review pass

- import-resolvers/zig: `..` above the repository root now returns null
  instead of aliasing a same-named root file (`../bar.zig` from `main.zig`
  is not `bar.zig`); the stale "extension is stripped and re-added" comment
  is corrected to what the code does.
- variable-extractors/configs/zig `extractType`: read the `type:` field only.
  The positional fallback returned the INITIALIZER of `const f = target;`
  as its type and gave up on compound annotations (`*Foo`, `?[]const u8`).
  The comment claiming 1.1.2 has no `type` field on variable_declaration
  was wrong (verified by AST dump) — and it is what led the review to
  suspect the callable-flow `extractAssignment` callback, which was
  already correct for `extern var f: T;`.
- receiver detection: only a FIRST parameter named `self` is the receiver.
  `emitZigScopeCaptures` tags first-position parameters
  (`@type-binding.first-parameter`), `interpretZigTypeBinding` requires the
  tag as well as the name, so `zigReceiverBinding` no longer turns
  `fn f(a: u32, self: T)` into an instance method.
- resolvers/zig.test.ts: both suites `describe.skipIf(!zigAvailable)`
  (Swift/Dart pattern) — the grammar is an optionalDependency.
- tree-sitter-languages.test.ts: the Zig parsing case gates on
  `isLanguageAvailable` instead of a catch-all `return`, so an installed
  grammar that fails to load fails the test; comment no longer calls Dart
  and Swift npm optionalDependencies (they are vendored).
- test/helpers/literal-collectors: `DIR_LANG` gains `zig`, so literals under
  `languages/zig/**` are validated against the Zig grammar alone rather than
  against every grammar.
- walkers.ts `isShapeLike` doc: Union IS included (via isClassLike, wired by
  Zig's union member container); Typedef remains the only deferred one.
- language-config `ZigBuildZonConfig.pathDeps` doc: values are the raw
  `.path` strings; the resolver normalizes.

Tests: zig-import-resolver (+1), zig-extractors (+3).

* fix(zig): address third gitnexus-check review pass

- language-config `parseZigBuildZon`: the `.dependencies = .{` header and
  the per-entry `.<name> = .{` headers are matched only OUTSIDE string
  literals (per-offset string mask + `matchZonHeader`). A `.name` or
  `.description` value spelling `.dependencies = .{ .fake = .{ .path = … } }`
  used to be taken as the block and returned the fake dep instead of the
  real top-level one.
- import-resolvers/zig: an absolute import (`@import("/foo.zig")`) returns
  null. The path walker skipped every empty component, so the leading `/`
  vanished and `/foo.zig` resolved as importer-relative `src/foo.zig` — an
  in-repo edge for an import Zig rejects as outside the module path.
- tree-sitter-languages.test.ts: the Zig parsing case gates on the PACKAGE
  being installed (`createRequire().resolve`, minus a deliberate
  `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out), not on `isLanguageAvailable`,
  which is false for absent AND for installed-but-broken bindings — so a
  load failure (ABI mismatch, bad export) now fails the test instead of
  skipping it, as the comment already claimed.
- walkers.ts `isShapeLike` doc: `Union` sits in `isClassLike` because that
  is the label set the ownership walkers consult, not because unions
  inherit — Zig has no inheritance and no heritage hooks. The previous
  wording ("inheritance-capable owner") said otherwise.
- Not re-fixed (already addressed in the second pass, findings carried
  over): "receiver = any parameter named self" — `interpretZigTypeBinding`
  only sources a first-position parameter as `self`; `zigReceiverBinding`'s
  doc now states that invariant. "`DIR_LANG` has no zig entry" — it does.
  Extended one level out: `BASENAME_LANGS` (`zig.ts`) and `PREFIX_LANGS`
  (`ZIG_`) map to the Zig grammar too, so extractor configs and the
  export-detection set are validated against Zig alone. That immediately
  caught a dead `childForFieldName('parameters')` in
  method-extractors/configs/zig `zigParameterList` (there is no such field;
  the named-child lookup was already the one doing the work) — removed.

Tests: zig-import-resolver (+2: absolute path, header inside a string);
both fail on the previous code.

* fix(zig): address fourth gitnexus-check review pass

- language-config: `parseZigBuildZon` only accepts a `.path` that is a
  DIRECT field of a dependency entry. Nested blocks inside the entry body
  are blanked (string-aware, offsets preserved) before the `.path` regex
  runs, and a match starting inside a string literal is rejected, so
  `.dep = .{ .url = "…", .meta = .{ .path = "x" } }` no longer becomes a
  path dep. Regression test in zig-import-resolver.test.ts (fails on the
  previous code).
- tree-sitter-languages test: the "grammar is absent" case now drives the
  loader's real `source.load()` catch branch — `node:module` is stood in
  with a `createRequire` whose require throws MODULE_NOT_FOUND for
  `@tree-sitter-grammars/tree-sitter-zig` and delegates everything else —
  instead of the `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out, which has its
  own test. It also asserts the opt-out flag is NOT set and that other
  grammars still load (non-fatal optional failure).

Not re-fixed:
- "Return type is read from the wrong tree-sitter field": tree-sitter-zig
  1.1.2 has NO `return_type` field on function_declaration — the type after
  `)` is the `type` field (AST dump: `builtin_type "i32" field=type`; the
  proposed `childForFieldName('return_type')` is null for every function).
  A pin test in zig-extractors.test.ts asserts both the grammar fact and
  that `returnType` is extracted (`void`, `!*Counter`).
- "`DIR_LANG` has no zig entry": it does (added in the first pass and
  answered again in the third); the finding is carried over unchanged.

* fix(zig): address fifth gitnexus-check review pass

- tree-sitter-languages test: the Zig "functions, structs, enums, and
  imports" case now asserts the `import.source` capture for
  `const std = @import("std");` (the fixture's only import), so a query
  change that drops Zig import matching fails it instead of passing
  unchanged.

Not re-fixed:
- "Return type is read from the wrong tree-sitter field": carried over from
  the fourth pass unchanged. tree-sitter-zig 1.1.2 has no `return_type`
  field on function_declaration; the return type IS the `type` field, and
  the pin test added in the fourth-pass commit
  (zig-extractors.test.ts, `childForFieldName('return_type')` is null,
  `returnType` = `void` / `!*Counter`) proves it.
- "`DIR_LANG` has no zig entry": carried over unchanged for the third time;
  the entry exists since the second-pass commit.

* feat(zig): export fn visibility, opaque containers, named test blocks, member ownership

Ports the parts of upstream PR #305 (closed, unmerged) that our Zig
provider lacked, plus two gaps found while porting.

- `export fn` / `export var` (C-ABI linkage, never `pub`) are exported;
  the pub/export predicate is now shared by the export checker and the
  method/variable extractors' visibility (`hasZigVisibilityKeyword`).
- `const H = opaque { … }` is a Struct-labelled container (it may own
  methods, never fields) in both the structure queries and the scope
  query; ZIG_CONTAINER_TYPES is the single source for the extractor
  configs.
- `test "name" { … }` blocks are Function nodes named by the string
  node WITH quotes, so `test "add"` beside `fn add` cannot merge onto
  Function:<file>:add; `test_declaration` joins FUNCTION_NODE_TYPES and
  the Zig method config names it in the enclosing-function walk, so
  calls inside a test attribute to the test. Anonymous `test {}` and
  decl-tests `test add {}` are scopes without a node (an empty-name hook
  result stops the walk instead of falling through to the identifier of
  the function under test).
- Empty container bodies (`struct {}`, `opaque {}`) no longer mint a
  nameless Property: tree-sitter-zig 1.1.2 recovers them as a
  container_field with a MISSING identifier; #not-eq? guards in both
  queries and the field extractor drop it.
- Owner walk (`findEnclosingClassInfo`): an anonymous container bound
  by the enclosing `variable_declaration` takes the binding identifier,
  same shape as the Go `type_spec` branch. Before this NO Zig member
  had an owner — zero HAS_METHOD / HAS_PROPERTY edges for Zig.

Not ported from #305, deliberately: `builtInNames` (a bare-name call-site
drop filter; `alloc`/`free`/`append`/`print` are the most common user
method names in Zig and `std.*` receivers are already external via the
import binding), `usingnamespace` (removed in Zig 0.15), `@cImport`,
`build.zig` ignore, and the web-app changes.

* test(zig): absent-grammar case owns GITNEXUS_SKIP_OPTIONAL_GRAMMARS

The loader parses the opt-out variable lazily once per module copy, so
under `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=zig` (or `all`) — a supported way
to run — the fresh loader took the opt-out branch and the "not the
opt-out path" assertion failed before the absent-binding path ran.

Clear the variable for the fresh module and restore it in `finally`,
instead of returning early: the branch stays exercised in every
environment. Verified: fails on the previous code under `=zig`, passes
with and without the variable now.

* fix(zig): declare the Union relation pairs — analyze aborted on any union

`gitnexus analyze` exited 1 on every Zig repository that declares a
`union` (including the zig-basic fixture itself): the member-ownership
commit made `union_declaration` a MEMBER_OWNER, so HAS_PROPERTY /
HAS_METHOD edges are emitted FROM a Union node, but `Union` was not in
LINKABLE_LABELS, so the schema's scope-bridge cross product never
generated a `FROM Union` pair and LadybugDB rejected the edge
(`labelPair: "Union|Property"`). Resolver tests stayed green because
they never write to the DB.

- `Union` joins LINKABLE_LABELS (also bridges `Tag{…}` constructor
  references); the three hand-written `→ Union` target pairs move to the
  generated half, per the STRUCTURAL_PAIR_DDL rule.
- structural-pair-coverage gains an optional-grammar corpus with
  zig-basic (`Union|Property`, `Union|Method` sentinels), skipped when
  the grammar is absent.
- Rust `union_item` note updated: the three gates it cited are widened.

Note for reviewers: the DDL fingerprint changes (#2808), so existing
indexes are rebuilt on next analyze.

* feat(zig): resolve path deps through the dep's build.zig and src/root.zig

The bare-name resolver only knew `src/<name>.zig` and `src/main.zig`.
`zig init` has written `src/root.zig` for libraries since 0.12, so the
default library layout never resolved. Now: the root the dep's own
build.zig declares (`b.addModule("<name>", .{ .root_source_file =
b.path("…") })`, name-matched module first), then src/root.zig,
src/<name>.zig, src/main.zig. `normalizeZigDepPath` is shared by the
loader and the resolver.

* feat(zig): Const/Variable defs, member imports, receiver typing, generic type constructors

Coverage gaps found by indexing idiomatic Zig against the branch:

- Const / Variable nodes: ZIG_QUERIES had no @definition.const /
  @definition.variable, so `pub const VERSION`, error sets and type
  aliases were absent and zigVariableConfig never ran. Rules are gated on
  the literal `const` / `var` keyword — tree-sitter-zig 1.1.2 parses
  statement assignments (`x = 5;`, `x += 1;`, `_ = expr;`) as keyword-
  less `variable_declaration`s, and the scope query minted a phantom
  local per assignment and one `_` per discard. Container and @import
  bindings are skipped via `shouldSkipDefinitionCapture`.
- Imports: `const X = @import("x.zig").X` (named / alias), `const X =
  ns.X` where `ns` is an @import binding of the file (promoted to a
  named import), and `pub usingnamespace @import(...)` (wildcard, with
  `expandsWildcardTo`). All three lost the file-level IMPORTS edge.
- Receiver typing: `var x: T = undefined` / decl literals `const x: T =
  .init()` (annotation), `var c = T.init()` / `mod.T.init()` (call
  return), `List(u8){}` (instantiation literal); `normalizeZigTypeName`
  drops the comptime argument list.
- Generic type constructors `fn List(comptime T: type) type { return
  struct {…}; }`: the returned container is a Struct/Union/Enum named
  after the fn, owns its members (HAS_METHOD / HAS_PROPERTY), binds in
  the module scope beside the Function def, and is emitted ahead of it
  so a named import binds the type.
- `export` vs `pub`: `visibility` is now `pub`-only (Zig-module fact);
  `isExported` keeps `pub|export` (visible outside the unit, as C's
  external linkage). `export fn` without `pub` is not reachable from
  other Zig files.
- Extractor configs share `zigContainerName`; ast-helpers' owner walk
  learns the type-constructor shape.

Tests: zig-idioms fixture (10 resolver cases), extractor/interpret unit
cases for each rule.

* fix(zig): address sixth gitnexus-check review pass

- Windows absolute `.path` deps (`C:\x`, `C:/x`) return null from
  `normalizeZigDepPath` like POSIX ones; a `/`-only check let them
  through as repo-relative.
- `parseZigBuildZon` accepts the `.dependencies = .{` header only at
  brace depth 1 (a direct field of the file's `.{`), so a same-named
  field nested in an earlier struct cannot hijack the block.
- `importsExecuteWhereWritten: false` on the provider: `@import` is
  compile-time name lookup (as C `#include`, Rust `use`); a body-level
  `@import` is no longer marked `runsOnlyWhenCalled`.
- Namespace imports record the MODULE as `importedName`
  (`zigModuleNameOf`: last path segment without `.zig`), per the shared
  contract; the local handle stays `localName`.
- Keyword-less `<ident> = @import(…)` (`_ = @import("x.zig")` in a test
  block) is a `side-effect` import: file edge, no binding. Only
  `const`/`var` declarations bind a name or feed alias promotion.
- `extractZigFunctionName` doc: an empty name is falsy, so the enclosing-
  function walk skips the test node and continues to the File; it does
  not "end" there.

Not re-fixed: "DIR_LANG has no zig entry" — carried over for the fourth
pass in a row; `test/helpers/literal-collectors.ts` has had `zig` in
`DIR_LANG` (line 91) and `BASENAME_LANGS` since the second-pass commit.

Regression tests: absolute-path spellings, nested `.dependencies`
decoy, namespace/side-effect interpretation, function-scoped `@import`
not deferred (all four fail on the previous source).

* fix(zig): address seventh gitnexus-check review pass

- The scope query's `@import` binding rules are keyword-gated (`"const"` /
  `"var"`, first-child anchored) like every other binding rule, and the
  keyword-less `<ident> = @import(…)` statement has its own
  `@import.side-effect` rule. Tree-sitter queries cannot express "no
  keyword child", so that rule also matches the keyword shapes and
  `emitZigScopeCaptures` drops those (they are the binding rules'
  matches). Behaviour is unchanged from the sixth-pass fix — the existing
  side-effect test covers it — the query text now carries the guard the
  finding asked for.

Not re-fixed: "DIR_LANG has no zig entry" — fifth pass in a row;
`test/helpers/literal-collectors.ts` has had `zig` in `DIR_LANG` since
the second-pass commit. Left for a human reviewer to close.

* fix(zig): resolve @import of the repo's own build.zig modules (F3)

Bare-name imports were resolved through build.zig.zon path deps only, so
the module a repo's ROOT build.zig declares for itself —
`b.addModule("lightpanda", .{ .root_source_file = b.path("src/lightpanda.zig") })`,
imported by name from 378/567 Lightpanda files — never produced an IMPORTS
edge, and nothing reached through `lp.X` resolved. A repo with a build.zig
but no build.zig.zon got no resolution config at all.

- language-config: `parseZigRootModules` (static scan of the root build.zig:
  `addModule("<name>", …root_source_file = b.path("<p>.zig")…)`, and
  `createModule`/`addModule` bindings named via `addImport("<name>", m)` or
  `.imports = &.{ .{ .name, .module = m } }`; generated / `.url` / computed
  modules are skipped) → `ZigBuildZonConfig.rootModules`.
- `loadZigBuildZon` → `loadZigBuildConfig`: reads the zon AND the root
  build.zig; null only when neither contributes.
- resolver: root modules are consulted before path deps; std/builtin/root
  still never resolve.
- fixtures: zig-idioms gains a Lightpanda-shaped root module (+ decoy
  `addOptions().createModule()`); new zig-rootmodule (build.zig, no zon).

Corpus (Lightpanda): IMPORTS 3014→3389 (378 edges to src/lightpanda.zig,
was 0), CALLS 13885→13989, ns.f() 79.3%→83.3%,
param.m() type=ns-qualified 43→46/417.

* fix(zig): import every @import in expression position; resolve @import("x").f()

Both query sets only saw `@import` as the value of a const/var or under
`usingnamespace`, so an @import in any other position produced no file
edge: Lightpanda's `pub const Interfaces = .{ @import("a.zig"), … }`
registration table (288 modules), call arguments
(`CounterEnum("size", @import("ArenaPool.zig").BucketSize)`), comparison
operands (`JsApi == @import("x.zig").JsApi`) and member-call receivers
(`try @import("dump.zig").root(...)`) — 417 of 3,401 in-repo import pairs
had no IMPORTS edge, and the 80 inline-receiver calls resolved 0 times.

Scope query: a catch-all `@import.inline` rule matches every `@import`
builtin; `emitZigScopeCaptures` drops the ones a binding rule (or the
keyword-less side-effect rule) already claimed (by string-node id) so a
bound import is never doubled, emits the rest as side-effect imports once
per distinct source per file, and binds a member-call receiver as a
namespace import whose local name is the builtin's own text — the
`@reference.receiver` text on that call is identical, so the shared
namespace-receiver lookup (Case 1) resolves the member in the imported
module.

ZIG_QUERIES: the three variable_declaration/usingnamespace-anchored
`@import` rules collapse into the same single builtin rule (the structure
phase only skips import matches; one match per builtin keeps
tree-sitter-languages' exact-capture assertion intact).

Lightpanda corpus (zig-corpus-check, before → after): IMPORTS 3014 → 3426,
in-repo pairs missing 417 → 5 (4 under a default-ignored `cache/` dir, 1 a
commented-out import the census regex counts), `@import(..).f()` 0/80 →
72/80 (the 8 left are `@import("root")` and non-import builtins the census
mislabels), CALLS 13885 → 13959; every other line unchanged.

* feat(zig): model file-structs — a file with top-level fields is a Struct named after the file

In Zig every file is a struct; one that declares top-level fields is an
instantiable type whose name is the file stem (`Page.zig` declares `Page`,
`@typeName` agrees), and its top-level `fn`s taking `self` are its methods.
Lightpanda spells 413 of 567 files this way and, before this, `page.getArena()`
on a `page: *Page` parameter resolved 23 of 993 times (2.3 %) — `impact` on
`Page.getArena` reported 0 callers for 159 call sites, and 2,395 top-level
fields were ownerless Property nodes.

Definition phase: `((source_file (container_field …)) @definition.struct)` +
the class extractor names it from the file path (`zigContainerName(source_file,
filePath)`); top-level fns/fields are owned through the new
`LanguageProvider.resolveFileTypeOwner` hook (consulted by
`findEnclosingClassInfo` when the walk reaches the tree root, and by the
method/field extractors' owner lookup) — ids become `Method:<file>:Page.getArena#0`
/ `Property:<file>:Page.session` with HAS_METHOD / HAS_PROPERTY edges.

Scope phase: `emitZigScopeCaptures` emits a Class scope over the whole file
(same range as the Module scope, nested under it — the pair `canParentScope`
already admits) plus a Struct def anchored on it; member NAME bindings are
hoisted back to the Module scope by `zigBindingScopeFor` so `Page.init()`
(namespace member) keeps working, while ownedDefs stay in the Class scope so
`populateClassOwnedMembers` stamps the owner. The file-level `const Page =
@This();` alias no longer mints a Const (it would shadow the Struct); `@This()`
aliases in type position (`self: *SigHandler` in Sighandler.zig, nested
`Self`) are rewritten to the container name so receivers resolve. A namespace
import of a `.zig` file gets a NAMED twin of the file stem so `x: *Page` in the
importer binds the type as well as the module.

Shared, additive: `resolveFileTypeOwner` hook; `filePath` threaded to
`ClassExtractionConfig.extractName` / `extractOwnerName`; nameless
`definition.struct` passes `getLabelFromCaptures` like `definition.class`
already did (extractor synthesizes the name).

Lightpanda corpus (zig-corpus-check): param receivers typed by a file import
23/993 → 993/993; `self.m()` 99.2 → 100 %; annotated locals 11.6 → 23.2 %;
CALLS 13,885 → 15,689; HAS_METHOD 1,477 → 8,003; ownerless Property 2,395 →
276; Function/Method 8,378/1,518 → 2,562/7,330; no row regressed.
Fixture `zig-filestruct` (Page/Session/Sighandler/util) + unit tests pin the
shape, the stem naming, the alias rewrite, the namespace twin and the
unchanged namespace-file behaviour.

* test(zig): expression-position import case sees the file-struct type twin

* fix(zig): stop reading member calls `x.f(arg)` as direct calls named `f`

tree-sitter-zig spells `field_expression` as `object:`/`member:`; the shared
callable-flow reader only knew `property`/`field`/`method`, so every Zig
member call collapsed to a DIRECT call named after the member and the
solver fanned each argument out to every same-named callable
(4,761 cap warnings on Lightpanda, `Global.deinit -> Global.deinit`
self-loops through `pub const release = deinit;`).

Shared (grammar-neutral, receiver-gated):
- `memberParts` also reads `member` (only C/C++ `offsetof_expression` and
  JS `class_body` expose that field, without a receiver field).
- A member call is a field-stored-callable invoke only when a MEMBER store
  (`o->run = handler`, `self.f = target`) or a declared callable-typed field
  is visible — a same-named plain binding no longer gates it.
- `direct-callee-name` requires a direct designator: `.init(x)`,
  `' '.join(x)`, `string.Join(x)` name no callee to seed by simple name.
Zig: formals are numbered without the leading `self`, so `r.run(target)`
joins `cb` and yields `Runner.run -> target`.

Goldens for python/csharp regenerated: the only drift is the dropped
`direct-callee-name` on `' '.join(...)`, `text.strip().ljust(...)`,
`string.Join(...)`.

Lightpanda: cap-warnings 4761 -> 2, cvf self-loops 10 -> 0,
CALLS 13885 -> 13857 (28 removed, all callable-value-flow: 10 self-loops,
17 same-name fan-out, 1 lost `on -> TypeErased.start`; +1 correct
`Arena.alloc -> allocator`).

* fix(zig): bind container field types so `self.field.m()` resolves (F5)

A container's field types were never bound on its Class scope: the scope
query's `container_field` rule captured only the name, and
`emitZigScopeCaptures` synthesized no `@type-binding.field` group. The
compound resolver reads member types from that scope
(`typeOfMemberOnClass` → `classScope.typeBindings.get(field)`), so
`self.session.name()`, `self.counter.incr()` — Lightpanda's dominant
cross-object call shape — resolved 9 of 2803 times (0.3 %).

- query.ts: capture `type: (_)? @declaration.field-type` on
  `container_field` (enum variants have none).
- captures.ts: per typed field, push a `@type-binding.field` group (name =
  field, type = the type text, `@This()` aliases rewritten to the container
  name like parameter types); anonymous inline containers are skipped. The
  binding lands on the container's Class scope — the file's Class scope for
  a file-struct — since `zigBindingScopeFor` hoists only declaration names.
- query.ts/captures.ts: `const page = self.page;` / `var s = self.session;`
  one-level field aliases become `@type-binding.alias` bindings whose "type"
  is the RHS path; the resolver's member-alias branch re-resolves it as a
  receiver chain. Import aliases (`const Counter = counter.Counter;`) are
  dropped — they are named imports.
- interpret.ts: `@type-binding.field` → 'annotation',
  `@type-binding.alias` → 'assignment-inferred' (an annotation on the same
  binding wins).

Corpus (Lightpanda, zig-corpus-check): self.field.m() 11/2803 (0.4 %) →
1433/2803 (51.1 %); ident.m() bound=local-field-access 29/1902 (1.5 %) →
307/1902 (16.1 %); chain.m() 146/5022 (2.9 %) → 642/5022 (12.8 %);
CALLS 15838 → 18066. self.m() / free f() / ns.f() unchanged.

Tests: unit (zig-extractors) — one @type-binding.field per typed field with
sigils stripped and aliases rewritten; the binding hosted on the container's
Class scope (file-struct: the file's Class scope, not Module) with the
written spelling as declaredSpelling; field aliases bound to the RHS path
and never for import aliases. Integration (zig-idioms `holder.zig`,
zig-filestruct `Page.zig`): `viaField → incr` ×2 into counter.zig,
`viaAlias → get/twice`, `sessionName → name` / `sessionLabel → name` into
Session.zig. All fail without the change. The optional-payload capture
`if (self.opt) |c| c.incr()` is not asserted (F6).

* fix(zig): `pub const X = @import(…)` at file scope republishes X (reexportsName)

Lightpanda's `lightpanda.zig` is one long list of `pub const Arena =
@import("Arena.zig");`, and most files name their types through it (`const
lp = @import("lightpanda"); const Arena = lp.Arena;`, `arena: *lp.Arena`).
The scope side treated those bindings as plain imports of the hub file, so
the hub never published the names it re-exports and a third file's `const
Arena = lp.Arena;` (promoted to a named import of `Arena` from the hub) found
nothing.

`emitZigScopeCaptures` now marks named/alias import groups whose declaration
is a file-level `pub const` — the `@import(...).X` form, the alias promotion
`pub const Bar = ns.Bar`, and the file-struct type twin of `pub const Arena =
@import("Arena.zig")` — and `interpretZigImport` sets the shared contract's
`reexportsName: true` on them (the Python `__init__.py` shape, consumed by
`buildReexportClosures`). Private and fn-local bindings stay unflagged.

Not covered here: a receiver ANNOTATED with the dotted hub path (`arena:
*lp.Arena`) — Case 3 of the receiver-bound pass looks the member up with
`findExportedDef`, which only sees locally declared names; following
re-exports there is a shared change left for a follow-up.

* fix(zig): type receivers through `const X = <type expr>;` aliases (F7)

`const LocalAlias = Local;`, `const T2 = Thing;` (alias of an alias/import)
and `const B = util.List(u8);` (an INSTANTIATED generic type constructor)
were plain `@declaration.variable` bindings, so `LocalAlias.mk()`,
`var l = LocalAlias.mk(); l.go()`, `T2.make()`, `B.init()`, `B{}` and
`var x: B` all typed nothing (review repro r3-flow b1..b9; Lightpanda:
`pub const Proto = HtmlElement;` x68, `const Allocator = std.mem.Allocator`
x104, `pub const KeyIterator = GenericIterator(...)`, fn-local
`const R = ...(...)`).

Model: a `@type-binding.alias` binding of the alias NAME to the value's type
text — Rust's `let x = y` / JS's `const B = Foo`, source
'assignment-inferred' — NOT a TypeAlias def. Reasons: (1) the shared
machinery already chains typeBindings (`followChainedRef` in the extractor,
`followChainPostFinalize` after propagation), so `var l = LocalAlias.mk()`
and `var x: B` reach the target through the alias with no new shared code;
(2) nothing shared follows a `TypeAlias` def to its target — `isShapeLike`
only makes the alias itself a member owner (TS object-type aliases) — so a
relabel would have needed language-named shared code; (3) graph node ids
are UNCHANGED: every alias stays `Const:<file>:X`. `normalizeZigTypeName`
already drops the comptime arguments, so `util.List(u8)` binds `util.List`
and resolves through the namespace import (Case 3). The identifier /
member shapes also take `var` (`var cur = orig; cur.go()` — the cursor
idiom, same binding as Rust's `let x = y`).

Heuristic, stated as such: a CALL value is kept only when the callee's last
identifier is TitleCase (Zig's naming convention for types), because the
grammar cannot tell `util.List(u8)` from `util.makeThing()` and the latter
belongs to the call-return rules; the call-return group is dropped for the
same TitleCase shape so the two never race on match order. Import bindings
(`const Stack = @import("x.zig").Stack`), promoted namespace-member aliases,
enum/decl literals (`.foo`) and the `type:` annotation of
`var b: T = undefined;` are excluded.

Not done: the two-hop `pub const bridge = js.Bridge(T); bridge.accessor()`
chain. `js.Bridge` is a Function that RETURNS `bridge.Builder(T)` (a call,
not a container), so the alias binds `js.Bridge`, Case 3 finds a Function
with no members in js.zig, and Case 3b is skipped for a namespace head.
Following that hop needs a namespace-member return-type route in shared
code (or a Zig `resolveQualifiedReceiverMember` hook that re-implements
member lookup without the model); left for a follow-up.

Corpus (Lightpanda, `harness/zig-corpus-check.mjs`): CALLS 15838 -> 16051
(+213, 0 removed), `ident.m() bound=local-alias` 6/63 -> 36/63,
`local-call` 159 -> 176, `module/unknown` 110 -> 116, `local-other`
271 -> 273; `self.m()`, `free f()`, `ns.f()` unchanged or up.

* fix(zig): one alias rule set — F7's alias rules subsume F5's field-access alias rules

* fix(zig): type locals through try/catch/orelse, return types and payload captures

F6 of the gitnexus-check review. Three gaps in the value flow that types a
local receiver, all measured on Lightpanda:

1. `@type-binding.call-return` needed the `call_expression` as the DIRECT
   value child, so `const p = try Page.init(…)` (2,551 sites), `… catch
   return` (410) and `… orelse return` typed nothing. The rule is now one
   keyword-gated declaration match; `emitZigScopeCaptures` unwraps `try`,
   `catch`, `orelse` and parentheses (`zigUnwrapValue`) and decides what the
   value types (`zigCallReturnTypeOf`): a module-level receiver still names
   the type (`Counter.init()` → Counter, Rust `Foo::new()`); a free call
   binds the callee name (`makeThing`); a member call on a fn-LOCAL receiver
   (parameter / local / payload — Zig forbids shadowing, so "declared in the
   fn" is exact) binds the compound `node.asElement()` the shared resolver
   walks to the method's return type — instead of typing `el` as `Node`. A
   TitleCase callee (`List(u8)`) is a type constructor and binds nothing.

2. No `@type-binding.return` existed. `fn make() !*Thing` now binds
   `make ↦ Thing` in the enclosing scope (Module for free fns, the container's
   Class scope for methods, where the compound resolver reads it). Builtins,
   `type`, `@TypeOf(…)` and comptime type parameters (`?*T`) bind nothing;
   `@This()` / `Self` returns name the container. `normalizeZigTypeName` now
   strips the error union BEFORE the payload's sigils, so
   `Allocator.Error!*Page` → `Page` (it used to leave `*Page`).

3. Payload captures had no binding at all. `populateZigRangeBindings`
   (registered as `populateRangeBindings`) types `for (items) |it| / |*it|`,
   `for (items, 0..) |it, i|`, `if (opt) |v|`, `if (call()) |v|`,
   `while (it.next()) |x|` from the SUBJECT's written type minus one layer
   (`[]T` element, `?T` payload) — declining when the layer is not visible
   (`ArrayList(T)`) — and the same projection for `const t = items[i]` /
   `opt.?` / `ptr.*`. `catch |err|` and `switch` prongs are skipped.

Corpus (Lightpanda, gate before → after): CALLS 15838 → 17853;
`ident.m() bound=local-try/catch/orelse` 11/1298 → 584/1298;
`local-call` 159/1282 → 398/1282; `payload` 82/1085 → 233/1085;
`other-recv:call_expression` 5/991 → 457/991; `local-other` 271 → 364;
`self.m()` 100 %, `free f()` 97.5 %, `ns.f()` 83.4 % unchanged; nothing down.

Not covered: `const t = ns.f()` (a namespace fn's return type across files —
Case 3 has no path from a namespace head to a callable's return binding),
and expression receivers (`items[i].run()`, `o.?.run()`).

* fix(zig): resolve leftover fixture merge markers (Page.zig)

* fix(zig): reconcile F6 value inference with F7 aliases and F5 field bindings

- A fn-local TitleCase receiver (`const R = generic.List(u8); var l =
  R.init();`) is a type alias (F7), not a value local: `R.init()` names the
  type `R` like `Counter.init()` does at module level, so `l` chains
  R → util.List → push. F6's local-receiver rule now excludes TitleCase heads.
- The F6 unit helper only collects the value-inferred / return kinds it
  owns; F5 field and F7 alias bindings for the same names are asserted in
  their own suites.

* fix(zig): give function-local and anonymous containers an identity (F8)

`const R = struct {…}` declared inside a fn (Lightpanda's reflection.zig
has ~20, one per builder) all collapsed onto one `Struct:<file>:R` with one
`R.get`; anonymous containers (`std.sort.pdq(…, struct { fn lessThan … }
.lessThan)`, `const byte_size = struct { fn it … }.it;`, `?struct { min,
max }` field types) had no identity at all, so their fns were OWNERLESS
Methods (`Method:<file>:lessThan#3`) that collided across a file.

`zigContainerName` now yields the graph IDENTITY on both phases:
  - function-local named: `<enclosing callable>$<name>` — `Reflect.string$R`
    (Java local-class `$` chain; `populateClassOwnedMembers` leaves it whole);
  - anonymous: `<host>$<ordinal>` — `build$1`, `Outer$1`, `Page$1`
    (javac's `Outer$1` numbering per host, in source order);
  - a `test` host is keyed `test@L<line>` (its string does not survive the
    class extractor's qualified-name normalization).
`zigContainerBindingName` keeps the spelling code writes (`R`) for scope
bindings and `@This()` alias rewrites (`@declaration.binding-name`).

Structure phase: bare `(struct|enum|union|opaque_declaration)` rules mint the
local/anonymous nodes via the class extractor; `shouldSkipDefinitionCapture`
keeps exactly one rule per container (`zigContainerAnchor`); a new
grammar-neutral `resolveContainerTypeOwner` provider hook lets the shared
owner walk name a container from context, so `Method:<file>:Reflect.string$R
.get#0` and its HAS_METHOD source agree by construction. Scope phase: the
wrapper group splits name/binding-name for locals and anonymous containers
get synthesized `@declaration.<kind>` defs (`is-synthetic`).

Lightpanda: ownerless Methods 14 → 0, fns without a node 55 → 0, ownerless
Properties 276 → 5, HAS_METHOD 8003 → 8074, HAS_PROPERTY 7275 → 7403,
CALLS 15838 → 15857, Struct 1905 → 2199; no resolution bucket dropped.

* fix(zig): re-add the implicit receiver on the call side so both method-call spellings reach the callback formal

`extractFunctionParameters` sliced the leading `self` off the formals, which
lined up `r.run(target)` (target@0 ↔ cb@0) but lost the explicit spelling
`Runner.run(&r, target)` (&r@0, target@1 ↔ cb@0): the callback never joined
its formal and `run → target` was missing (PR #1432 review by koriyoshi2041).

Formals are numbered once per function while the receiver differs per call
shape, so the fix lives in `extractCallArguments`: keep `self` as formal 0
and prepend the receiver as actual 0 when the callee is a member call on a
VALUE receiver — chain head is a fn-local name that is not TitleCase, the
same value-vs-type rule F6 uses. Namespace / type / decl-literal receivers
(`Runner.init(cb)`, `helpers.apply(cb)`, `List(u8).init`, `.init(cb)`) get
no prepend. Known residual gap, documented: a module-level value receiver
(`global_runner.run(cb)`) is not fn-local and still misses.

Tests: the F2 integration case now asserts both spellings plus a namespace
call; the unit contract pins `self@0, cb@1` and the per-call actual index.

* fix(zig): address eighth gitnexus-check review pass

- Named dependency modules: `parseZigBuildModuleRoots` scanned
  `addModule("<name>", .{ … })` with a `[^}]*` regex, so a nested field
  before `.root_source_file` (`.imports = &.{ .{ … } }`) ended the match
  at the inner `}` and demoted the module to an unnamed fallback — the
  first exe/lib root in the file then answered `@import("<name>")`. The
  named lookup now walks the balanced `addModule(…)` argument list
  (same scanner as `parseZigRootModules`, comment-stripped, string-aware);
  the unnamed fallbacks are unchanged. Regression test in
  `zig-import-resolver.test.ts`.
- Type-position `@import`: `var x: @import("m.zig").T = undefined;` was
  read as an import binding of `x` on both sides — the query rules match
  the `type:` child like a value, and `isZigContainerOrImportBinding`
  scanned every named child — so `x` was never declared and became a
  named import of `T`. The helper now skips the `type:` field, and
  `emitZigScopeCaptures` drops binding-rule matches whose `@import` sits
  in the annotation (`isZigTypePositionImport`) without claiming the
  source, so `x` binds as a variable and the file edge survives as a
  side-effect import. Regression tests in `zig-extractors.test.ts`
  (variable extractor + scope captures).
- Union in the class-capture skip guard: the parse-worker's inline
  class-like predicate lacked `Union`, so a `Union` definition bypassed
  `shouldSkipClassCapture` unlike every other `ClassLikeNodeLabel`.
  Added the label; no Zig behavior changes (Zig defines no skip hook), so
  no test.
- File-owned method ids in `findEnclosingFunctionId`: the arity lookup
  used `findEnclosingClassNode` while the owner came from the file-owner
  aware `cachedFindEnclosingClassInfo`, so a Zig file-struct's top-level
  fn produced `Method::Page.get` without the `#<arity>` suffix. It now
  uses `findEnclosingClassNodeOrFileOwner`, the definition-phase lookup.
  Consistency fix only: `ParseWorkerResult.calls` / `.assignments` (the
  sole consumers of this id) are merged but not read since #942 — CALLS
  edges come from the scope pipeline, whose ids were already right — so
  no observable graph change and no test.

Not re-fixed:
- `test/helpers/literal-collectors.ts` `DIR_LANG` has no `zig` entry
  (raised for the seventh time): the entry exists (`zig:
  SupportedLanguages.Zig`, added by the second-pass commit), so
  `languages/zig/**` literals are already validated against the Zig
  grammar alone; documented in the PR body since the fifth pass.

* fix(zig): keyword-gate the constructor type-binding rules

The three `@type-binding.constructor` rules (`const p = T{…}`, `mod.T{…}`,
`List(u8){…}`) matched any `variable_declaration` with an identifier and a
`struct_initializer`, keyword or not — and tree-sitter-zig 1.1.2 parses a
re-assignment `p = T{…};` (and `_ = T{…};`) as the same node type. So an
assignment minted a constructor binding for `p` in its own block, and one
for `_`. Zig's static typing makes the extra binding redundant (`p`
already carries its type from its declaration: annotation, constructor or
inferred value), so it cost little, but it declared nothing and stood out
against every other binding rule (`@declaration.variable`, the import
rules, the call-return rules), which are keyword-gated for exactly this
shape. Split each rule into `"const" .` / `"var" .` variants, like the
call-return rules.

Regression test in `zig-extractors.test.ts`: `p = T{…}`, `q = mod.T{…}`,
`l = List(u8){}` and `_ = T{…}` after their declarations yield only the
three declaration bindings (fails on the previous query). The zig,
callable-value-flow, grammar-literal and tree-sitter-languages suites are
unchanged.

Raised twice by gitnexus-check (passes on 2026-08-18 12:42 and 12:56).

* fix(zig): re-baseline the callable-flow capture fingerprints, keep `await f<T>(x)` a direct callee

The `benchmarks (GITNEXUS_BENCH)` CI job gates two capture fingerprints
that this branch's shared callable-flow change (3e62b99a) moved without
re-baselining: `bench/python-scope/baseline-fingerprint.txt` and four
languages in `bench/scope-capture/baselines.json` (csharp, cpp,
typescript, kotlin). Both `--check` runs pass on origin/main and failed
on this branch; every other language matched its baseline on the same
run.

Drift, verified by dumping the canonical matches on both trees:
- csharp / kotlin / python: exactly the intended change — a MEMBER call
  (`string.Join(x)`, `.forEach { }`, `' '.join(x)`, `.ljust(w)`) no
  longer carries `direct-callee-name`; the argument fact is unchanged.
- cpp: `choice.select(1)` (cpp-deleted-overload) drops an INDIRECT
  invoke + its synthetic `@reference.call.free` that were gated only by
  the same-named free `select` binding; the site is a genuine method
  call already captured as `@reference.call.member`. capture_groups_fp
  4605 -> 4601.
- typescript: `await svc.verify<T>(x)` (member) and `initializer()(cb)`
  (call-of-call) drop the name as intended. But `await verifyToken<T>(x)`
  — a DIRECT call — lost it too, because tree-sitter-typescript parses
  `await f<T>(x)` as `call_expression(function: await_expression(f),
  type_arguments, …)` and the new direct-designator gate saw an
  await_expression, not `f`. `wrappedExpression` now unwraps
  `await_expression` (no named field, so the field-based unwrap missed
  it), restoring parity with main for the direct spelling while the
  member spelling stays nameless. Regression test added; it fails
  without the unwrap on both assertions.

Gates run locally: scope-capture --check (15 languages), python-scope
--check, import-target --check, tsc, eslint, prettier, the callable-flow
/ golden / tripwire / resolver test files (33 files), full suite with
coverage (82.9/71.5/89.1/86.4 vs 26/23/28/27 thresholds).

* test(zig): fail CI when the optional Zig grammar is absent

`@tree-sitter-grammars/tree-sitter-zig` is an optionalDependency, so every
Zig suite gates on `isLanguageAvailable(Zig)` and the ABI load-smoke accepts
a clean load failure for an optional grammar. Both are the right contract for
a platform with no prebuild, and together they leave a hole: if the grammar
never installed on any CI runner, this PR would merge with all eight Zig
resolver suites plus the structure-phase suite reported green-by-skip, having
never executed the native Zig parser once.

Close it with the `GITNEXUS_REQUIRE_FTS` idiom already used for the FTS
suites. `GITNEXUS_REQUIRE_ZIG=1` declares "this runner has a prebuild, the
grammar MUST be here", and a missing grammar becomes a failure instead of a
skip. tree-sitter-zig@1.1.2 publishes prebuilds for {darwin,linux,win32}-
{x64,arm64}, so the flag is set on two required jobs that all run on covered
platforms: the sharded ubuntu `tests` job and the three-OS `abi-assert` job.

- test/helpers/optional-grammar.ts: the registry mapping a language to its
  require-variable, plus `describeGrammarPresence`, a presence assertion that
  FAILS when required-but-absent. Deliberately a separate test rather than
  flipping the suites from skip to fail: a skipped suite reports success, so
  only a failing test can turn "Zig never ran" into a red job.
- parser-loader-abi.test.ts: the optional exemption is revoked for a language
  the environment declares required, so an ABI-broken Zig binding fails the
  smoke instead of passing as a clean absence.
- optional-grammar-gate.test.ts: pins the two ways the gate could silently
  never fire — reading a variable name CI does not set, or accepting a value
  CI does not write.

Nothing changes for a run that leaves the variable unset: local runs and any
future prebuild-less platform still skip. Verified both directions --
`GITNEXUS_REQUIRE_ZIG=1` alone: 149 passed, 0 skipped; with
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` forcing the grammar away it fails 2 tests
with an actionable message; with the skip flag but no require flag it is
green-by-skip exactly as before.

Addresses the test-only blocker in the gitnexus-check review of #1432.

* fix(zig): type the optional-grammar gate by grammar key, not language

The gitnexus-check finding on parser-loader-abi.test.ts:155 is right, and
none of the gates caught it: `tsconfig.json` includes only `src/**/*`, so
neither `tsc --noEmit` nor CI typechecks the test tree, and vitest strips
types without checking them. Confirmed with a scoped tsc run over the file:
`error TS2345: Argument of type 'string' is not assignable to parameter of
type 'SupportedLanguages'`.

Not fixed with the proposed `key as SupportedLanguages` cast, which would
assert something false: `listGrammarSources()` yields one row per SOURCES
entry, including variants like `typescript:tsx` that are not enum members.
`isOptionalGrammarRequired` now takes the grammar KEY it is really given,
and the registry keeps a `satisfies Partial<Record<SupportedLanguages,
string>>` so every key we write is still pinned to a real language.

Two new cases cover the failure mode the type error was pointing at — a
registry key that can never match what the ABI smoke passes, leaving the
gate configured-looking and permanently inert: every OPTIONAL_GRAMMAR_ENV
key must be a key `listGrammarSources()` yields and must be marked optional
there, and an unregistered variant (`typescript:tsx`) must not be required
even with the variable set.

Same blind spot, two more latent errors in files this PR adds, both fixed:
`Parser.Language` is not an exported member (use the `setLanguage` parameter
type, as parser-loader-abi.test.ts already does), and the `ParsedImport`
filter did not narrow the union, so `localName` was read through a `!` on an
arm that has no such property — now a type predicate. The one remaining
error under the same probe, in `resolvers/callable-value-flow.test.ts:319`,
predates this branch (authored 2026-07-17, on main) and is left alone.

structural-pair-coverage's optional-grammar case switches from
`it.concurrent.each` to `it.concurrent.for`: only `for` passes the test
context as a second argument (`each`'s callback is `(...args: T[])`), and
that context carries the dynamic `skip()` the per-language gate calls.
Behaviour is unchanged — grammar present: 10 passed; grammar forced away:
9 passed, 1 skipped.

Whole test tree typechecking is a separate, much larger job: the same probe
over `test/**` minus fixtures reports 734 pre-existing errors across the
repo. Out of scope here.

* fix(zig): address tenth gitnexus-check review pass

- `normalizeZigDepPath`: normalize backslashes BEFORE the absolute-path
  check. A UNC dep (`\\server\share\dep`) used to slip past the check and
  normalize to the repo-relative `server/share/dep`; root-relative `\dep`
  had the same hole. Both now return null. Regression case added to the
  absolute-spellings test with the files those misreadings would resolve.
- `bindPayloads`: a pointer capture `for (pages) |*p|` now records `*Page`
  (declaredSpelling) instead of `Page` — the `*` is an anonymous payload
  child before the identifier. Method dispatch is unchanged (`rawName`
  strips the sigil), but a deref projection `const q = p.*;` now sees the
  pointer layer. New fixture fn `viaPtrCaptureDeref` + assertion; fails on
  the previous code (verified by stashing the src fix).
- `optional-grammar-gate.test.ts`: renamed the `typescript:tsx` case — the
  key IS a registry row; what makes it inert is the missing gate entry. Now
  also asserts a key no registry yields.
- `structural-pair-coverage.test.ts`: header updated — ten tables (not
  eleven) are absent from every rule's target side; `Union` left the set
  when Zig made it linkable.
- `language-classification.ts`: doc comment now names zig in the
  experimental set (added after Ring 1).

Not re-fixed (invalid findings):
- "owner-hook contract wired to an undeclared variable": stale-diff read —
  `findEnclosingClassInfo` declares `resolveFileTypeOwner` /
  `resolveContainerTypeOwner` as optional parameters (ast-helpers.ts:905,
  917) and parse-worker threads them at every call site; tsc compiles clean.
- "optional Zig grammar added unconditionally to the parsing fixture
  suite": the cited block only `fs.readFile`s the committed fixture file to
  assert it is non-empty — no parser or grammar load is involved.

* fix(scope-resolution): mark construction-site CALLS edges in reason (opt-in), enable for Zig

PR #1432 human review, item 2: a Zig struct literal `T{ .f = x }` (no
parens) is modelled as a CALLS edge to the type — the Rust `T { .. }` /
Go `T{}` shape — and nothing on the edge told it apart from an invocation
(`get_next_spawn → SpawnRequest` from seven `return SpawnRequest{ … }`).

`ScopeResolver.markConstructionSites` (default off): when set, the edge
emitted for a `callForm === 'constructor'` site gets ` (constructor)`
appended to its reason, in both emit paths — `local-call (constructor)` /
`import-resolved (constructor)` in the free-call fallback and
`scope-resolution: call (constructor)` in the reference bridge. The Zig
resolver opts in. `Reference` gains an optional `callForm`, copied from
the site by `buildReference`, so the bridge can see the form.

Why `reason` and not a property or edge type: relationships carry no
arbitrary properties, a new column changes the relation DDL and moves
SCHEMA_FINGERPRINT, and `reason` is the channel the IMPLEMENTS `-pointer`
receiver form already uses. Why opt-in: the unsuffixed strings are a
pinned contract asserted verbatim by the other language suites
(php/cpp constructor calls expect exactly `import-resolved`); every
non-Zig edge stays byte-identical.

Tests: `references-to-edges-call-form.test.ts` pins both vocabularies
and the default-off behaviour; `zig.test.ts` asserts
`Reflect.string → Accessor` / `Reflect.url → Accessor` carry
`local-call (constructor)` next to a plain invocation, and that every
marked edge targets a Struct.

* feat(zig): track qualified struct literals (`mod.T{…}`) as construction sites

PR #1432 re-test (issue comment on 97571d23): 163 qualified literals
`mod.Type{ … }` in a real project produced no CALLS edge at all, so only
same-file and imported-name literals were tracked as construction sites.

One query rule captures `(struct_initializer (field_expression object
member))` as `@reference.call.constructor` WITH the receiver. Captured as a
free constructor instead, the site resolves by its simple tail and a
workspace-unique `Thing` answers for `c.Thing{}` whichever module the
source named (measured: c.zig defines no `Thing`, the edge went to a.zig's).
With the receiver the site takes the receiver-bound namespace case — the
path `mod.fn()` takes — which resolves inside the module the receiver is
bound to: `a.Thing{}` / `b.Thing{}` bind their own files, `c.Thing{}` binds
nothing, `std.Thread.Mutex{}` binds nothing next to a local `Mutex`.

That case's edge now goes through `constructionSiteReason` too, so the
opt-in marker (`import-resolved (constructor)` / `global (constructor)`)
reaches it; `markConstructionSites` joins `ReceiverBoundProviderSubset`.
Byte-identical for every provider that does not set the flag.

Also answers the twelfth gitnexus-check pass: the `bodyNodeSet.size === 0`
guard on the extractor factories' no-wrapper branch is deliberate (a config
with wrappers whose node lacks one is a bodiless declaration); the two
comments now say so instead of reading as a universal last resort. Go's
method config, the only other empty-`bodyNodeTypes` config, never reaches
the branch (its `extract()` gates on method/function nodes the class-node
caller never passes).

Tests: new `zig-qualified-literal` fixture (same-named `Thing` in two
modules, a module without it, an external `std` qualifier next to a local
and an imported `Mutex`); `zig-basic` pins `pioneer.Pioneer{…}` and the
union `pioneer.Tag{…}` as marked construction sites.

* feat(zig): resolve hub re-exports, enum-variant receivers and type-named receivers (real-project audit)

Audit of three real Zig projects indexed with this branch (tigerbeetle 246
files, mach 132, ghostty 788): method reachability was 63 % / 35 % / 55 %,
and three shapes accounted for most of the misses.

1. Hub modules. Zig projects publish types through a file made only of
   re-exports (`pub const Terminal = @import("Terminal.zig");`, `pub const
   PRNG = @import("prng.zig");`, `pub const Thing = @import("thing.zig")
   .Thing;`). Such a file owns NO local binding, and `findExportedDef` reads
   local bindings only — so `terminal.Terminal.init()`, `t: stdx.Thing`,
   `var p = stdx.PRNG.from_seed()` and `h: stdx.BoundedArrayType(u8, 4)`
   all resolved to nothing. Measured before → after: CALLS into ghostty's
   `src/terminal/` from outside it 46 → 253 (150 `terminal.Terminal.` sites
   alone); into tigerbeetle's `stdx` hub from outside it 837 → 1500 (136
   static calls, 289 annotations). Method reachability: tigerbeetle
   2249 → 2272 of 3544, ghostty 2766 → 2865 of 5016, mach 1047 → 1051 of
   2967 (mach's hub publishes generic instantiations, `pub const Quat =
   q.Quat(f32)`, a shape this commit does not cover).
   `findExportedDefIncludingImportedNames` reads the finalized channel
   (origin import / namespace / reexport, def already resolved to the
   declaring file), refusing a name bound to two distinct defs. Opt-in per
   provider (`namespaceExportsIncludeImportedNames`): a module's imports are
   not its exports in most languages; Zig opts in because a hub member a
   consumer can name is public by construction. Used by receiver-bound Case
   1, Case 3, the compound resolver's namespace branch, and a new Case 2
   route that resolves a namespace-qualified class receiver (`stdx.PRNG`)
   through the same lookup.

2. Enum variants as receivers. `Operation.create_accounts.event_max()`
   (147 sites in tigerbeetle): a variant has no written type, but it has
   one — the enum itself. `emitZigScopeCaptures` now emits a field type
   binding per enum variant, so the field walk that already handles
   `self.session.name()` types `Op.create` as `Op`.

3. Receivers named after their type. `self` is a convention, not a rule:
   tigerbeetle writes `replica: *Replica` (777 of 1127 methods), mach
   `pool: *@This()` (764 of 833). Reading only `self` as the receiver
   labelled all of them `isStatic: true`, counted the receiver in their
   arity (`Counter.incr#1`) and sourced the scope binding as a plain
   parameter. `zigReceiverParameter` is the single rule for both phases:
   the FIRST parameter when named `self`, or typed as the enclosing
   container (`@This()`, its binding name, a `const X = @This();` alias),
   pointers / const / optionals stripped.

Fixtures `zig-hub` and `zig-receivers` pin each shape, including the
refusals: a private hub import does not leak, a foreign-typed first
parameter is not a receiver, a factory stays static.

* fix(zig): address thirteenth gitnexus-check review pass

- File-struct receivers named after the file stem were always static: the
  method builder called `isStatic` / `extractReceiverType` /
  `extractParameters` without the extractor context's `filePath`, so
  `zigReceiverParameter` could not name a file-struct (`fn add(ledger:
  *Ledger)` in `Ledger.zig`, no `Self` alias) and the fn came out static
  with the receiver in its arity (`Ledger.add#2`) — an id the scope side,
  which always has the path, never produces, so its CALLS edges went
  nowhere. `MethodExtractionConfig` now passes `filePath` as an optional
  trailing argument to those three hooks (same shape as
  `extractOwnerName`); the Zig config threads it through, every other
  config ignores it. Regression tests in `zig-extractors.test.ts` (unit)
  and `resolvers/zig.test.ts` (new `Ledger.zig` in the `zig-receivers`
  fixture: ids, `isStatic`, and the three CALLS edges); both fail on the
  previous source.
- `LINKABLE_LABELS` comment: the remaining `CLASS_KINDS` entries include
  `Namespace`.

Not re-fixed:
- "Ownerless-method assertion regex cannot match `.zig` graph IDs": the
  `[^:]+` segment consumes the whole file path (dots included) up to the
  second colon, and `[^.]+#\d+$` then matches only an owner-less name —
  `Method:src/Sorter.zig:lessThan#3` → true, `…:Sorter.sortBoth$1.lessThan#3`
  → false, checked with node.
- "Public namespace imports are never marked as re-exports": the shared
  `ParsedImport` namespace variant has no `reexportsName` field and
  `contributesReexportEdge` excludes namespace drafts on `base.kind` by
  contract; a `pub const X = @import("x.zig")` hub member is exposed
  through `findExportedDefIncludingImportedNames` instead, which is what
  the audit commit added for exactly that shape.
- "Private Zig namespace imports are treated as public hub exports": a
  private import cannot be named through the hub in code that compiles,
  and `findExportedDef` applies the same no-visibility rule to local
  defs; the finalized binding channel carries no `pub` bit to check.
- "Range binding mutates finalized scopes" and "unconditionally adds an
  optional Zig grammar to the fixture suite": refuted in the tenth and
  eleventh pass notes of the PR body, unchanged since.

* fix(zig): close the adversarial review's ten findings (8.2–8.12)

PR #1432 review 5095267917 on 34c53473 retained eight P1 and two P2
findings; each is reproduced on the new `zig-chains` / `zig-buildmodules`
fixtures with the decoy that made the old answer wrong, and pinned by a
test named after its number.

- 8.2 per-build-module import tables (`parseZigBuildModules`): a source
  resolves a bare name through its own module's `addImport` table (root
  file, else deepest root directory), fails closed when same-directory
  modules disagree, and follows `addImport("api", dep.module("core"))`
  through the dep's `addModule`; repo-wide names and zon deps remain the
  fallback.
- 8.3 module-level value receivers (`zigHostValueNames`) prepend the
  implicit `self` like fn-locals, so `global_runner.run(cb)` joins `cb@1`.
- 8.4 deep member aliases (`@import("lib.zig").B.work`, `lib.B.work`)
  keep the written owner: the module is bound as a namespace and the
  alias's use sites are rewritten to `receiver . member`; only one-level
  aliases are promoted to named imports.
- 8.5 container-hosted containers get owner-qualified identities
  (`A.Item`, `B.Item`, `Outer.Inner`), minted by the bare-container rule,
  while the scope keeps the lexical binding.
- 8.6 result-location `.init(…)` / `.{…}` under an annotation, a return
  type or a field type emit the call / construction site with the
  expected type as receiver.
- 8.7 Zig arm in bench/import-target (five dispatchers, config-free
  fingerprint) + baselines row; `--check` passes.
- 8.9 fn-local `@import` bindings and their uses are keyed per callable
  (`m$f_sib_a`), so sibling fns no longer share one namespace bucket.
- 8.10 `ScopeResolver.resolveNamespaceChains` (opt-in, Zig only): Case 1
  / Case 2 / Case 3 and the compound resolver walk a qualified receiver
  segment by segment — republished modules, nested types, enum variants
  through the module — refusing ambiguous hops. Off, every lookup keeps
  its one-hop split; the 70 resolver suites are unchanged.
- 8.11 `@import("a.zig").Thing{}` binds the module as a namespace in type
  position; `List(u8){}` / `lists.List(u8){}` get constructor sites.
- 8.12 a fieldless file whose top-level fn takes the file's own type
  (`self: *@This()`, `self: *Self`) is a file-struct; two over-matching
  ZIG_QUERIES rules are filtered by `shouldSkipDefinitionCapture`.

Also asserts the committed `opmod.Op.lookup.event_max()` call in zig-hub.

* fix(zig): address gitnexus-check findings on 215f70e3

- receiver-bound Case 3 wraps its reason in constructionSiteReason, like
  Case 1 and the nested-type route of Case 2 (one vocabulary per provider)
- resolveZigImportInternal rejects drive-qualified absolute imports
  (C:\foo.zig), the same test normalizeZigDepPath applies; unit case added
- the compound resolver's chain seed also tries the whole receiver as the
  qualified class (opmod.Op), as a bare class-name head already does
- markConstructionSites contract text names the receiver-bound routes

The return_type field claim is refuted: tree-sitter-zig exposes a fn's
return type as the type field (checked on the grammar).

* fix(zig): a build-module alias bound to an unindexed root fails closed

resolveThroughBuildModules returned undefined when the containing module
bound the alias to a file that is not indexed, which let the repo-wide
addModule map answer under the same name (gitnexus-check on 5299c552).
The module's table is the authority for its aliases: bound-but-unindexed
is null, only an unbound name falls through. Unit case with a same-named
repo-wide decoy, plus the outside-module file that still reaches it.

* fix(zig): an unindexed root module fails closed, never a same-named zon dep

The root build.zig's addModule declaration is authoritative for a bare
name when it binds it; a root that is not indexed used to fall through
to a build.zig.zon path dep of the same name — a different declaration
answering under the name (gitnexus-check on fe24b37f). Same rule as the
build-module tables. Unit case added.

* bench(receiver-resolution): rebaseline for the Zig lang-resolution fixtures

The receiver-resolution gate (#2856/#2899) landed on main after this branch
forked and counts call drops over test/fixtures/lang-resolution, which this
branch extends with the zig-* fixture projects. Regenerated with
`measure.mjs --update-baseline`: callDrops 102 -> 113, all 11 new drops in
.zig files, shape `no-chain`.

Every new drop is a call whose callee has no node in the corpus, not a
resolver regression: `std.Build.Module.addImport` in the three build.zig
fixtures (7, classified in-program), `std.sort.pdq` in Sorter.zig (2,
unknown), `std.Thread.Mutex{}` / `std.mem.Allocator{}` literals in
zig-qualified-literal (2, unknown, the fixture asserts std stays external),
and one `.init()` decl literal on a generic instantiation
(`const u: Stack(u16) = .init()`, in-program). Shape arm unchanged.

feat(ingestion): mint Destination nodes from AsyncAPI 3.x documents (#3140)
* feat(ingestion): read AsyncAPI 3.x documents into broker addresses

Adds a format-driven reader that turns the `operations[]` entries of an
AsyncAPI 3.x document into (broker, address, direction) triples, plus the
protocol-to-broker map behind it. Nothing consumes it yet.

The reader lives outside `frameworks/spring/` on purpose, like
`destination-key.ts` and for the same reason: an AsyncAPI document is a
published artifact emitted by generators across several language toolchains
and written by hand as often as generated. The entry criterion is therefore
the document format -- a root `asyncapi` key -- and never the generator.

AsyncAPI 2.x is refused under its own countable reason rather than mapped.
Its `publish`/`subscribe` are inverted relative to 3.x `send`/`receive`, so
a naive mapping reverses every direction in the async graph while leaving it
connected: nothing fails, the arrows simply point the wrong way. A silent
skip would be indistinguishable from "this service publishes no document",
which is the one thing the refusal count has to be able to tell us.

The broker is read twice over -- from the operation's bindings and from its
channel's server protocol -- and the two readings must agree. A destination
keyed on the wrong broker joins a stranger, and with the document
contradicting itself there is no way to tell which reading is right, so the
operation is refused rather than decided by a coin flip.

An unmapped protocol passes through as its own literal instead of being
dropped, because `destinationNodeKey` takes a plain string precisely so a
non-Spring caller can attest to a broker Spring has no member for.

* feat(cli): add --asyncapi-spec, an explicit path to AsyncAPI documents

Threads an `asyncApiSpecPath` option from the CLI, the server analyze
endpoint, and the programmatic entry through to `PipelineOptions`. Nothing
reads it yet; the reader added in the previous commit is still unwired.

Shaped deliberately after `springActuatorPath`, the existing option for an
out-of-band artifact: an explicit local path, accepting a directory or a
single file, resolved against the repository root so a committed
`docs/asyncapi` and an absolute cache populated by something else are both
natural, and `undefined` keeping the feature entirely off. Mirroring that
option rather than inventing a mechanism is what lets a downstream consumer
point the reader at documents fetched out of band without patching a file
here.

`analyze --watch` REJECTS the flag, exactly as it rejects --spring-actuator.
The watcher reacts to source changes and nothing watches a document
directory, so honouring it there would read the documents once and then
serve a stale answer for the rest of the session -- worse than refusing,
because it looks like it worked.

Additive only: 49 inserted lines, no deletions and no modified lines. Every
new interface member is optional and every forward is an object-literal
spread of an undefined value, so with the option unset the analyzer takes
byte-identical paths.

* feat(ingestion): mint Destination nodes from AsyncAPI documents

Wires the reader into the destinations phase. With `--asyncapi-spec` set,
every `send` operation emits PUBLISHES_TO and every `receive` emits
CONSUMES_FROM against the ordinary resolved `Destination` node -- same key,
same `address` property -- so a document and a source site that name one
address on one broker land on ONE node and the two halves of a conversation
meet. Verified end to end: an address named only in a document is minted
with the right broker and direction, and an address a source site already
resolved stays a single node with its own `literal` provenance while the
same address on a different broker stays separate.

This claims only what a document states -- that the service talks to that
address, on that broker, in that direction -- and never which method does
it. The addresses in one document partition by (broker, action) into buckets
that usually hold more than one operation, so any assignment past a bucket
of size one is a heuristic, and a wrong one attaches a real address to the
wrong handler: a false connection wearing the clothes of a resolved one. The
edge therefore starts at the document, not at a callable. That is weaker
than a source-derived edge and worth having anyway, because it is available
where the source supplies nothing at all -- a programmatically registered
listener, a broker with no patterns here, a language whose messaging idiom
nobody has taught this codebase yet.

Documents are read even when the source pass found no messaging, which is
why the early return had to move: a repository whose brokers are invisible
to the patterns is precisely the case a published document covers, and an
early return keyed on source sites skipped the documents exactly there.

Their counters are kept in their own block rather than folded into the
existing ones. `refusalsByReason` is the denominator of the SOURCE
unresolved fraction, and a mistyped specification directory must not be able
to make the source look worse than it is. The block is absent -- not zeroed
-- when no path was configured, so "not asked for" stays distinguishable
from "asked for and found nothing"; those need different answers from an
operator and one zero cannot say which happened.

The direction assertion is the one that matters and it is pinned by type,
not by existence: inverting the mapping in the source tree fails exactly one
test, because every other assertion passes identically under both readings.

* docs: document --asyncapi-spec and why step 4 of the cascade stays empty

Adds the flag to both READMEs and to the three byte-identical copies of the
CLI skill, which a sync test pins together.

Also rewrites the note on the `specification` seam in the address cascade.
It said "nothing supplies it today", which was true and is now misleading:
a reader exists, and the hook is still unsupplied because of a decision
rather than for want of one.

A document names addresses; it does not name the method that uses one. To
hand an address to a particular candidate something must choose which of the
document's operations belongs to it, and the only division both sides agree
on -- (broker, action) -- leaves buckets that usually hold more than one
operation. On a real generated document exactly one bucket of four was
unambiguous. Every assignment past a bucket of size one is a heuristic, and
a wrong one puts a REAL address on a joining node under the wrong site: a
false connection wearing the clothes of a resolved one, which is the outcome
the keying rule exists to prevent.

The note also records the two things that would change that and are not
heuristics -- a document carrying the implementing symbol, or a
configuration source answering the `${key}` the candidate already recorded
-- and that the second wants its own resolver, since what it needs is the
placeholder key rather than the candidate.

* fix(ingestion): refuse the document shapes that would forge a join

Four ways a conformant AsyncAPI document could mint a Destination that
connects two services which have said nothing about each other. Every one is
reachable from ordinary 3.x vocabulary, not from malformed input, and each is
now a countable refusal.

A PARAMETERIZED ADDRESS is a pattern, not a place. Two services that publish
`{env}.orders` share a template; one deploys with env=prod and the other with
env=staging, and keying on the template text merges them into a single node
with a publisher on one side and a subscriber on the other. This is the
document-side twin of `overridable-config-default`, which argues the same
thing about `${key:default}` in source. A channel declaring `parameters` is
the specification's own statement that its address is a template, so the
detector is a reading rather than a guess; the `{` test catches generators
that template without declaring.

ANY BINDINGS KEY WAS TAKEN AS A PROTOCOL. AsyncAPI allows `bindings` to be a
Reference Object, so the map's own key can be `$ref` -- and passed through,
that becomes half of a join key carrying no broker information at all. Two
services that both reference shared bindings and both name `orders` then land
on one node, defeating the broker-in-key rule that keeps `kafka orders` and
`rabbit orders` apart. A broker must now be spelled like a protocol name.

A BROKER CONTAINING A SPACE COLLIDES, because the node key joins with one:
("kafka orders", "x") and ("kafka", "orders x") are the same key. That was
latent while every broker came from Spring's closed union. This module is the
first caller to feed the shared helper text that a document wrote, which is
exactly the condition under which it stops being latent, so it is closed here
-- at the producer -- rather than by changing an encoding that `routeNodeKey`
shares.

THE ADDRESS WAS TRIMMED, while the source cascade keeps an address exactly as
written so `" orders "` stays its own node. Two producers of one key held
opposite whitespace policies and the document side erred toward joining.

Also: fold the transport-security protocol variants (`kafka-secure`,
`secure-mqtt`, `wss`, `stomps`, `https`) onto their base protocol. The
`amqp`->`rabbit` argument already in this file demands it -- AsyncAPI's server
vocabulary distinguishes them and its bindings vocabulary does not, so a
secured cluster's own document was being read as self-contradictory. Treat a
channel with no `servers` as available on all of the document's servers, which
is the specification's default and was costing every single-server document
its destinations. Bound the address and operation-id lengths, because
`generateId` concatenates rather than hashes, and bound total operations
across the run rather than only per document.

Read each file through ONE handle for both the size gate and the read, as
`actuator-runtime.ts` does and for the reason its comment gives (CodeQL
js/file-system-race): re-resolving the path lets a swapped file bypass the
cap, and the out-of-band cache this option reads is written by other tooling
by definition. Open it with O_NONBLOCK: the type check that rejects a FIFO is
unreachable without it, because opening a FIFO for reading blocks in open(2)
until a writer appears -- found by writing the test first and watching it time
out rather than fail.

Count symlinked entries and walk truncation instead of dropping them in
silence. A symlinked cache and a wrong path were producing identical results.

* fix(analyze): rebuild when documents are configured, and report what was read

An AsyncAPI document is external to git freshness in exactly the way an
Actuator snapshot is: replacing one moves no commit and dirties no file. The
option's own README paragraph advertises an absolute cache written by other
tooling, and on the second run of that workflow the already-up-to-date fast
path fired, no document was ever opened, and the previous run's addresses were
served as current. Measured, not reasoned: editing a document and re-running
printed "Already up to date" and left the old address in the graph; with this
change the same probe re-reads and the new address replaces it.

So an enabled run forces a rebuild and dropping the option forces one more, to
clear document-derived evidence -- the treatment `springActuatorPath` already
gets, for the same reason. Only the FLAG is recorded in index metadata, not
the path: Actuator retains its inputs so future scans keep excluding them,
whereas a committed document is deliberately NOT excluded (it wants its real
`File` node), so there is nothing to retain and recording the path would put
an operator's directory layout into metadata for no consumer.

That also settles a defect it would have been tempting to patch separately. A
synthetic `File` node for an out-of-tree document carries a path that is in no
write set and is not covered by `isGraphWideNode`, so an incremental writeback
dropped the node while keeping its edges -- which then COPY against a row that
was never written, and fail into an IGNORE_ERRORS retry that reports success.
A forced rebuild has no incremental subgraph to get that wrong.

Distinguish the two meanings of `resolution: 'specification'`. That value
belongs to the address cascade and means a CODE candidate was resolved through
the step-4 hook; a node minted from a document has no code site and now says
`asyncapi-document`. Reusing one string would leave a query that groups by
provenance unable to separate an address a document states from one a document
was used to resolve, and only the second is a claim about source.

Report what was read. The stats block was justified on the grounds that an
operator must be able to tell a mistyped directory from a repository with no
documents -- and nothing surfaced it, so the justification was aspirational. A
configured path that yields nothing, or a walk that hit a bound, now warns
unconditionally, as `spring-auto-configuration.ts` does for the same class of
input. The phase summary carries the refusal breakdown rather than only the
totals, because the unresolved fraction is the number this work is judged on
and a bare count says how big the gap is without saying what would close it.

Tests for the three wiring lines that were individually deletable with a green
suite, following the templates already in the repository: a row in the
`--watch` rejection table, the CLI-threading assertion beside the Actuator
one, and the shipped-skill fragment that pins the flag in all three copies.
Also pin `filePath: ''` on a spec-minted destination -- the half of the keying
rule that stops a shared node becoming collateral damage of one document's
next change -- and the in-repo `File` branch, which was dead-code-able.

* fix(ingestion): close the join-forging paths a second review round found

The `$ref` exclusion added last round fixed one instance of a class and left
the class open. A `bindings` map key of `x-scs-function` -- an ordinary
Specification Extension, which generators emit -- still became the broker, so
two unrelated services carrying one vendor annotation and one address landed
on ONE node whose broker half said nothing about any broker. And
`{ kafka: {}, x-internal: {} }` read as two brokers, losing a conformant
document and reporting it as self-contradictory, which also made any document
author a one-line saboteur of their own cross-service links.

So the two readers are now separate functions with opposite defaults, and the
header says why they must be. `servers[].protocol` is a FIELD DECLARED to hold
a protocol: an unrecognized value there is the document's own claim and passes
through, because refusing it would lose a destination the document states
plainly. A `bindings` MAP KEY is not that -- the specification puts `$ref` and
`x-` in the same namespace -- so a non-protocol key is the EXPECTED case and
only AsyncAPI's binding vocabulary may answer. The syntactic test that was
applied to both was the right rule for one of them.

The walk fix from last round introduced something worse than it reported. A
shared abort flag meant depth exhaustion in ONE branch terminated the whole
traversal, so ten good documents beside a twelve-deep unrelated subtree were
kept or lost depending on whether that subtree sorted before or after them.
Truncation and budget-exhaustion are now separate: depth returns from its own
branch, and only a genuinely global bound stops the walk.

Rewriting `protocol.ts` dropped the whitespace check from the server-protocol
path and made the node-key collision reachable again. The test written for
that collision last round caught it within the minute; the comment now records
that it was learned twice.

Everything else measured this round:

- The broker is the THIRD string that reaches a graph identifier, and it was
  unbounded while the header claimed there were two. A one-megabyte protocol in
  a document satisfying every other cap was measured producing a gigabyte of
  resident identifier strings, because `generateId` concatenates rather than
  hashes and the phase mints one id per node and per edge.
- The run-wide operation budget counted ACCEPTED operations, reproducing at the
  run level the exact defect the per-document cap was corrected for last round:
  a run whose every operation is refused never decrements it. Both now count
  operations EXAMINED, and `operation-cap` sets `truncated` -- it is a bound
  that stopped the operation count, which is what that flag is documented to
  mean.
- The channel-inherits-all-servers rule ran per operation. Hoisted: it depends
  only on the servers.
- A subdirectory that cannot be listed is counted rather than dropped, so a
  mixed-permission cache cannot report a clean, complete read.
- The read LOOPS, like the Actuator reader this claims to follow. A single read
  was never short across seven hundred probes on APFS, but POSIX permits it and
  FUSE mounts with `direct_io` -- the deployment this option targets -- return
  short counts. A document truncated at a line boundary still parses, so the
  failure is silent: operations vanish with `refusals: {}`.
- `parameters: {}` no longer refuses a literal address; an empty container
  states nothing and generators emit them.
- A channel that is itself a Reference Object gets its own reason instead of
  `no-address`, which was telling operators their documents omit addresses when
  the reader simply stops one hop short.
- A multi-protocol document resolves from its operation's own bindings; only
  when those are silent does an inherited multi-protocol server set refuse, and
  under `ambiguous-server-default` rather than a reason that says the document
  contradicts itself. It does not.
- HTTP and WebSocket are refused for destination minting. For a broker the
  topic is the namespace; for HTTP the host is, so keying on the path alone
  would make every service exposing `/events` one node. A `Route` already
  models an HTTP endpoint, with its method in the key.
- The sniff window is a parse gate, not a read gate, and four kilobytes refused
  a good document behind a licence header.

* test(ingestion): pin the wiring and the reporting that were deletable

Three lines could be deleted with the whole suite green, and each of them
makes the feature partly or wholly inert: the forward from `run-analyze` into
`PipelineOptions`, the forced rebuild while documents are configured, and the
cleanup rebuild when the option is dropped. None is visible one layer up,
where the CLI test asserts on a mock's arguments.

One integration test closes all three. It drives the real `runFullAnalysis`
against a real repository and asserts, in order: the enabled run does not take
the up-to-date fast path and logs the rebuild; the destination reaches the
graph, which only happens if the option is forwarded; a document edited with
the tree clean and the commit unchanged is re-read; dropping the option
rebuilds once and removes the document-derived evidence; and the run after
that is up to date again -- the "rebuilds once" half, which rests on the
metadata being written as a fresh literal rather than merged, and which
nothing pinned.

The document lives OUTSIDE the repository on purpose. That is the workflow the
option is documented for, and it is the only one where the hazard exists:
editing a tracked file dirties the tree and forces a rebuild anyway, so an
in-repo fixture would pass with the freshness fix reverted. Verified by
reverting both: deleting the forward fails on the empty destination list,
deleting the forced rebuild fails on the missing log line.

Also pinned, each because deleting the code it covers left the suite green:
the `parameters` half of the templated-address refusal (its old test supplied
a braced address too, so the `{` half alone satisfied it); the phase actually
forwarding `symlinksSkipped`; the unconditional warning, whose whole argument
is that a tally nobody can see is not a tally -- captured through the
repository's own `_captureLogger`; a `.yml` document; a character device,
which is the case the `isFile` check exists for and which the FIFO test does
not reach; and the bound that stops a walk.

Reject an empty `--asyncapi-spec` at the CLI. It resolved to the repository
root and walked the whole tree, defeating this module's own rule that there is
no glob-based auto-discovery -- and the HTTP entry point already rejected the
identical value. Two doors onto one option must not hold different rules.

Surface the flag in the MCP context resource beside `spring_actuator`. It
matters more there than for its neighbour: Actuator annotates nodes the source
pass already found, while document reading mints destinations and edges with
no code site, and nothing said where they came from.

Log the configured path relative to the repository. The same change refuses to
persist that path to index metadata because it would record an operator's
directory layout; holding that rule for metadata and not for logs was holding
it in one place.

Both test files now clean up their temporary directories.

* style(ingestion): apply the repository's prettier contract

`quality / format` runs `npx prettier --check .`, and three files added by this
branch were not formatted to it. No behaviour changes: the reader's line
breaks and two test literals move, nothing else.

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

* test(ingestion): release the mini-repo handle the document test allocated

`setupMiniRepo` documents that the caller owns cleanup, and every other test
in this file calls `repo.cleanup()` in its `finally`. The AsyncAPI document
test removed only the document directory, so each run left a temporary
repository behind.

The two owners are separate on purpose: the document directory is a SIBLING of
the repository, placed outside the working tree so that editing it cannot
dirty the tree and force a rebuild on its own. The repo's cleanup therefore
does not reach it, and both calls belong in the same block.

* fix(ingestion): stop partial server evidence from reading as unanimous

Six review findings, every one a way this reader could name a broker the
document does not name. They share a shape: something is DROPPED rather than
refused, the remaining evidence agrees with itself, and an operation is
attributed with confidence to a broker its document never settled on. A wrong
broker is half a join key, so it does not produce a missing edge -- it produces
an edge to a stranger, reported as a fact.

CAPPED SERVER MAPS. A channel with no `servers` inherits all of them, and that
map is capped at 1,000. A document whose first thousand servers are Kafka and
whose thousand-and-first is JMS read as unanimously Kafka, because unanimity
was tested on the slice. Counted `server-cap` and set `truncated`, but neither
stopped the attribution. The inherited path now refuses under
`capped-server-default` -- checked BEFORE agreement, since a subset agrees with
itself for free.

ROOT SERVER REFERENCE OBJECTS. The Servers Object patterned field is
`Server Object | Reference Object`, so `{ $ref: '#/components/servers/prod' }`
is conformant. Reading `protocol` off the raw value dropped every one: an
all-reference document had no protocol at all, and -- worse -- a MIXED set lost
its disagreeing half and became unanimous. One hop is now followed, through
`#/servers` and `#/components/servers`; anything else is refused under
`unresolved-server-reference` rather than skipped.

CHANNEL BINDINGS. Only the operation's bindings were read. A conformant channel
carrying `bindings: { kafka: {} }` with no operation binding was dropped as
`protocol-unknown` while the document said plainly which broker it meant, and a
disagreement between the two levels was invisible. Both are read; a conflict is
`protocol-disagreement`.

EMPTY `servers`. "If `servers` is absent or empty, this channel MUST be
available on all the servers defined in the Servers Object" -- one sentence,
both cases. A zero-iteration loop returned `explicit: true`, which blocked the
inherited fallback and dropped valid operations.

POINTER DECODING ORDER. RFC 6901 percent-decodes the fragment BEFORE splitting
on `/`. The raw token was tested for a separator first, so `#/channels/orders%2Fv1`
passed a check it should have failed and then decoded into two segments -- a
pointer addressing `channels.orders.v1` was read as a channel named `orders/v1`,
inventing a channel the document never declared. A malformed escape is now
refused rather than resolved against its undecoded text. `~1` still resolves; it
is the pointer's own escape and belongs after segmentation.

THE SNIFF WINDOW. A fixed window decides by where the root key sits rather than
whether it is there, so every window is a false negative waiting for a longer
preamble -- 4 KiB was replaced by 64 KiB for that reason and inherited the same
defect. The whole text is scanned; it is already bounded and already in memory,
and the gate exists to skip the PARSE, which is the expensive half. A leading
UTF-8 BOM is stripped before both sniff and parse.

Twelve of the fourteen new tests were run against the unfixed reader and all
twelve failed; the other two are controls that must pass either way.

* refactor(ingestion): simplify AsyncAPI pointer and binding resolution

* fix(auto-sync): drop retired allowStale from group sync

allowStale was removed from SyncOptions, which broke typecheck and CI on this PR.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(watch): satisfy prefer-const and Prettier in auto-sync

The watch timers are assigned exactly once, so prefer-const rejected the
deferred `let` declarations. They are only read from `stop()` and the control
poll, both of which run after the assignments, so binding them at creation is
safe and drops the now-dead undefined guards.

Remaining files are formatting only.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(watch): make lock identity absolute and stop three fail-open paths

Lock owner identity was rendered by `ps -o lstart=` through localtime and the
active locale, so the same live process produced a different string under a
different TZ. A mismatch reads as PID reuse, so one daemon could reclaim a
mutex another still held. Pin TZ=UTC and LC_ALL=C.

The owner record also carried no hostname, so a holder on another machine was
judged by this kernel's view of its PID — always "stale" — and its lock stolen
whenever GITNEXUS_HOME is a shared volume. Record and compare the hostname, as
the index lock already does.

Ownership verification threw unconditionally on win32, which is reached once
per project per tick, so watch reported `running` and then failed every repo
forever. POSIX uid/mode cannot be checked there; skip those two assertions and
keep the dangerous-root, symlink, containment and internal-root guards.

Also: quarantine sweep now refuses a symlinked root instead of deleting
through it; an unreadable state file propagates instead of being rewritten as
empty state, which used to erase every repo's analyzed commit and failure
count; a failed staging cleanup no longer strands a published lock with no
release handle; and the concurrency runner settles every worker before
surfacing a failure so cancellation cannot orphan a live analyze fork.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(watch): land the deferred review findings

Six findings that were deferred from the review backlog, plus the docs they
change.

Worker heap: admission allowed `floor(availableMemoryGB / 2)` slots while every
fork was handed the whole machine's heap cap, so the budget meant nothing as
soon as an operator raised max_concurrency. Divide the cap by the repos
actually analyzed in parallel. The default single-project path is unchanged.

Registration: the parent registered without a branch, so it always took the
primary/flat arm and relabelled a pinned branch entry on the branch-fallback
path. Reproduce the worker's own resolveBranchPlacement decision instead.

Cancellation: requestCancellation cleared the only timer and settled nothing,
so a worker wedged past its safe point left the promise pending forever,
wedging activeRun and hanging `watch stop`. Add a 5s grace after which the
parent stops waiting and releases the IPC channel's hold on its event loop.
The child is still never killed — it may be inside native work.

overwrite_local_changes: `checkout --force` rewrites tracked files only, so
untracked sources survived and were indexed as if they came from the remote.
`git clean -fd -e /.gitnexus` after checkout; no -x/-X, so ignored paths and
GitNexus's own storage survive.

Quarantine: age alone never bounds a repo that fails every tick, since each
partial clone is younger than the retention window. Keep the five newest per
repo.

Validation: repo_git_timeout is now bounded by the lesser of an hour and the
sync interval, which is also the guard for the bare-number-means-seconds slip
(`600000` meant ~7 days and cleared the timer ceiling). And the remote URL's
final segment is validated at config load rather than failing once per tick
inside the sync loop.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(watch): release an errored worker, and stop rejecting dotted repo names

Three findings from the latest review pass.

The 'error' handler settles immediately rather than waiting out the grace, so
cleanup() clears the grace timer that would otherwise have released the child.
An errored IPC channel does not mean the worker stopped, so release it on that
path too — still no kill.

The traversal guard tested the raw path for '..', which also rejected an
ordinary name like owner/foo..bar that the repository-name rule accepts.
Traversal is a whole segment, so test segments.

The heap-cap test left two runs and their real timers pending; it now stubs
timers and settles both promises. Registration coverage now pins the branch
slot rather than leaving it implicit.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(watch): validate namespace segments and pin the stopped process identity

Replacing the raw-string `..` test with a per-segment one dropped a guard: a
segment like `..\..\outside` is not literally `..`, so it passed, and those
segments build the clone path — on Windows the backslashes are separators.
Hold every namespace segment to the same charset as the repo name, which keeps
a separator out of a segment while still allowing an ordinary `foo..bar`. The
final segment keeps its own check so a bad repo name keeps its own message.

The stop wait polled liveness by pid alone, so a pid reused mid-wait would
have it wait on an unrelated process and then report the watch stopped. Compare
the process start time recorded for the owner, which also returns sooner.

Registration now omits `branch` for a primary index instead of passing it as
undefined, so that call keeps the shape it had before this branch.

* fix(cli): ship auto-sync as the remote daemon, reserve gitnexus watch.

Keep analyze --watch for local incremental re-index and stop the top-level watch verb from starting a clone/pull loop.

* fix(auto-sync): reject invalid branch refs and verify status identity (#2493)

Co-authored-by: Cursor <cursoragent@cursor.com>

Stop interpolating a tampered ownerId into the stop-request filename; only basename-safe values are treated as owners.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): recognize auto-sync in the watch-process identity check (#2493)

Stop/status were still looking for a standalone watch token after the command rename, so a live gitnexus auto-sync start process would be refused as unrelated.

Co-authored-by: Cursor <cursoragent@cursor.com>

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(auto-sync): reject boolean max_concurrency instead of coercing it to 1 (#2493)

Number(true) is 1, so a YAML boolean would have passed the integer check and silently meant one worker.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): swallow status errors in the watch finally path (#2493)

An uncaught updateStatus rejection in finally became an unhandled
rejection. Skip the clone-root symlink test on Windows, where directory
symlinks need privileges. Align the group-lock comment with fail-closed
registry timeouts.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): catch cancelling status-write failures (#2493)

Fire-and-forget updateStatus('cancelling') could become an unhandled
rejection, the same class as the finally-path status write.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): ignore queued interval ticks after stop (#2493)

clearInterval does not cancel a timer callback already queued. Guard
runSafely on stopping so shutdown cannot start a new un-cancellable run.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(auto-sync): report stored watch status timestamps (#2493)

status should show when the watch last entered a state, not when the
CLI queried it. The failure-count test still expects 1 after a new
commit resets the streak; rename it so that reset is explicit.

feat(wiki): add grok local CLI provider (#3069)
* feat(wiki): add grok local CLI provider

Wiki generation can use `gitnexus wiki --provider grok` to spawn the
authenticated Grok Build CLI (`grok --prompt-file`) instead of an HTTP API key.

* style(wiki): prettier grok-client for CI format check

CI quality/format failed on grok-client.ts. Auto-format matches repo prettier so the GitNexus /autofix comment is applied locally.

* Update Grok CLI configuration to use empty allowlist and increase max tu

* Replace Grok tool allowlist with explicit denylist and strict sandbox

* Increase Grok max turns to 15 to accommodate prompt variance

* chore(wiki): drop Unreleased CHANGELOG hunk and restore lockfile libc selectors

Feature PRs do not own CHANGELOG.md. Restore the 16 libc platform selectors
deleted from package-lock.json with no dependency change.

* fix(wiki): resolve grok CLI through Windows cmd.exe shims

Extract resolveWindowsCliCommand from the local CLI client and use it for
grok detect/spawn so npm .cmd installs work without a shell. Keep
detectGrokCLI() returning the display name for the wiki menu.

* fix(wiki): wait for grok child close before timeout cleanup

Do not reject the grok spawn promise on the timeout timer. Kill the child,
escalate SIGKILL after 2s, and reject only on close (or a second 2s hard
deadline) so callGrokLLM cannot rm the sandbox while the process is alive.

* fix(wiki): reject incomplete grok stopReason and distinct parse errors

Honor JSON stopReason (end_turn or omitted succeeds; anything else throws).
Split empty-output / non-JSON / missing-text messages and include a truncated
stdout excerpt. Drop unused GrokConfig.workingDirectory.

* fix(wiki): keep grok temp dir on hung timeout and ignore stdin

Hard-deadline reject no longer removes --cwd while the child may still
be running. Spawn stdin is ignored so grok's unused pipe cannot EPIPE
the wiki process.

Live grok 1.0.5 with wiki spawn flags returns stopReason end_turn.
Omitted, null, or empty stopReason is no longer treated as success, so
generateLeafPage cannot write a page that never completed.

* test(wiki): remove grok temp dir after hard-deadline leak assertion

The hard-deadline test must keep the dir until close, then emit close so

* test(wiki): wait for grok temp dir rm after late close

Windows CI failed the hard-deadline test because 30 setImmediate ticks
cannot observe fire-and-forget fs.rm. Poll with real timers after close.

fix(lbug): scale the buffer-pool budget by the OS page-size granule ratio (#2631) (#2636)
* fix(lbug): scale the buffer-pool budget by the OS-page discard-granule ratio (#2631)

LadybugDB bills buffer-pool budget per discard granule, not per 4 KiB frame:
the engine's vm_region.cpp sets discardGranuleSize = max(frameSize, osPageSize),
claimFrame charges the whole granule when its first frame becomes resident, and
releaseFrame refunds only when the granule's last frame leaves — while
BufferManager::reserve measures eviction progress in refunded bytes and throws
'The buffer pool is full and no memory could be freed!' after three zero-refund
passes. On a 64 KiB-page kernel (Ascend/aarch64 openEuler — the #2631
reporter's host) that is 16 frames per granule: the same COPY bills up to 16×
the budget it needs on x86, and whole eviction passes can evict frames yet
refund nothing. Apple Silicon macOS (16 KiB pages) is the same mechanism at 4×.

Measured with the reporter's exact command and version: vllm-ascend needs a
(128, 256] MiB pool on 4 KiB pages — 64/128 MiB reproduce the reporter's
byte-identical error, 256 MiB and the 576 MiB adaptive pool succeed — so their
64 KiB host cannot survive on a page-size-blind budget.

Scale every derived pool size by granuleRatio = max(1, osPageSize/4096):
the per-element estimate, the COPY-safety floor, and the default cap (still
bounded by 80% of RAM). 4 KiB hosts are byte-identical to before — proven by
pinning the existing sizing tests to an explicit 4096 page size, which also
stops them drifting on 16 KiB Apple Silicon runners. GITNEXUS_LBUG_BUFFER_POOL_SIZE
keeps absolute precedence and 0 still restores the native default.

Also: bufferPoolExhaustionRemedy() gives the exhaustion error an actionable
cause→consequence→remedy message; the isLbugPageSizeFrameError comment that
called pool exhaustion 'a sizing problem, not a page-size one' is corrected —
that framing inverted when #2582 made pool size a function of a page-size-blind
estimate. Cannot execute on a 64 KiB kernel here: the scaled path is proven by
unit stubs plus the engine-source math above; the env override remains the
field escape hatch.

* feat(cli): actionable pool-exhaustion remedies at the COPY sites and a doctor pool line (#2631)

The node-COPY throw and the relationship-COPY warning now append
bufferPoolExhaustionRemedy() when the failure is the engine's pool-exhaustion
class: the raw binder text gave the operator nothing to act on, and on
non-4K-page hosts the pool bills up to pageSize/4KiB × faster than the sizing
was calibrated for. The relationship path appends the remedy once per bulk
load, not once per failed pair. doctor prints the effective pool size next to
the page-size line ('pool size 2048 MiB', with an '(×N page-size scaling)'
suffix on non-4K hosts) so support triage sees the sizing inputs at a glance.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* refactor(lbug): re-anchor getEffectiveBufferPoolSize's placement and reuse granuleRatio in doctor

Self-review fixes: the getter's insertion had orphaned resolveBufferManagerSize's
doc comment (it read as documenting the wrong function), and doctor's scale note
duplicated the granule math with a hardcoded 4096. granuleRatio is now exported
(it already carried the test-seam default param) and doctor consumes it.
No behavioral change — the sizing suite pins byte-identical outputs.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(lbug): keep the hintless pool default unscaled and make both remedies visible (#2631)

Review fixes:
- Scale only the analyze-path cap (scaledAnalyzePoolCap), not
  defaultBufferPoolSize: the pool is an eager native allocation at DB open
  (measured, see POOL_BYTES_PER_ELEMENT), so a page-size-scaled hintless
  default would hand a long-lived MCP process up to 80% of RAM — the #2557
  OOM exposure the 2 GiB cap removed. Fix the MAP_NORESERVE claim that
  contradicted that measurement.
- Log the rel-pair pool remedy (loadGraphToLbug returns warnings that no
  call site reads) and dedup it with a local boolean instead of matching
  the remedy's own wording.
- Label the GITNEXUS_LBUG_BUFFER_POOL_SIZE=0 sentinel as the native
  80%-of-RAM default in both the remedy and doctor instead of '0 MiB'.
- Extract poolSizeDoctorLine (pageSizeDoctorLines convention): mark env
  overrides, drop the scaling suffix that misdescribed absolute values.
- Fold _resetOsPageSizeCacheForTest into _setOsPageSizeForTests(undefined).
- Document the analyze-path scaling in both README env tables.

1c98e7c6dd fix(cli): make .agents/ skill mirror best-effort + exclude from dirty check
Address review findings on PR #2488:

- skill-gen.ts: wrap mirror-root mkdir and per-skill mirror writes in
  try/catch + warn, so a mirror failure (e.g. .agents/skills is a file)
  no longer aborts canonical community-skill generation or destroys prior
  output. Mirroring is now a weak side-flow, matching ai-context.ts.
- git.ts: exclude .agents/ + .agents/** from isWorkingTreeDirty so a
  tracked .agents/ dir doesn't permanently defeat the up-to-date fast path.
- README + --skip-skills help (en/zh): note skills also mirror to
  .agents/skills/ when .agents/ exists, and --skip-skills skips both.

Tests: +18 covering mirror failure paths (root-is-file, per-skill fail,
delete-then-rewrite ordering, namespace-scoped cleanup), dirty-check
excludes (real-edit regression, prefix collision, subdir .agents/,
non-git/git-missing conservative fallback), gate on file-not-dir, and
idempotency.

feat(skills): GitNexus Engineering Tool Kits (#2566)
* feat(skills): add ce-plan — GitNexus+PDG implementation-planning skill

Adds .claude/skills/ce-plan: a planning-only skill that builds
implementation-ready plans from GitNexus graph navigation (query/context/
impact/trace), bounded statement-level PDG slices (pdg_query, impact
mode:pdg, explain), and targeted source verification, with a context
ledger to prevent repeated reads and a machine-readable implementation
context pack (stable contract for a future ce-implement). Whitelisted in
.gitignore and registered in AGENTS.md and CLAUDE.md outside the
auto-managed gitnexus block.

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

* fix(skills): apply ce-plan validation findings (tool contract, consistency, conventions)

Tool contract: impact mode:'pdg' shape now includes the schema-required
direction param; CDG branch sense documented as the result 'label' field
(reason is cypher/raw-edge only); explain caveats corrected to its real
false-negative classes (cross-function TAINT_PATH is modeled).

Consistency: PDG slice homed in working memory (ledger keeps one-liners);
depth knob defined and category-overrides-baseline ordering stated;
call_depth (consumed by nothing) and content-hash bookkeeping dropped;
Never section folded into Hard rules; Phase 3 deduplicated to a pointer;
allowed-repeat escalations defined; budget/discard accounting clarified;
verification-commands gathering added to Phase 4; open_questions added to
the context pack.

From scenario runs: plans now pin the verified-at HEAD commit and index
freshness in a header, tag claims [verified]/[graph]/[inferred]/[assumed],
quote load-bearing tool output, prefer pre-hook-carrying npm scripts, and
support an out:<path> destination override; output path defined as the
Phase 1 target repo root.

Conventions: AGENTS.md 1.9.0 / CLAUDE.md 1.4.0 changelog rows + metadata
bumps; future ce-implement qualified as future.

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

* feat(skills): rename ce-plan → gitnexus-plan; add cross-CLI (Codex) entrypoints

Renames the skill dir, frontmatter, output filename convention, plan H1
(GitNexus Engineering Plan), the future executor handle
(gitnexus-implement), the .gitignore whitelist entry, and all
AGENTS.md/CLAUDE.md references. Follows the pr-swarm-review cross-CLI
pattern: SKILL.md is the canonical CLI-neutral spec, AGENTS.md § Engineering
planning is the Codex/any-agent entrypoint, and the README documents the
optional user-level ~/.codex/prompts/gitnexus-plan.md slash command plus an
invocation matrix. Skill prose de-branded from Claude Code (agent-neutral
verification layer).

Also fixes two post-review README contradictions: the anti-reread claim now
names the ledger's allowed escalations, and 'read-only by contract' is now
'planning-only' (the skill writes exactly one repo file — the plan); the
scope-creep rule and template §12 now agree on where deferred follow-ups
land. Drops the stale plugin-collision limitation.

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

* docs(skills): document Codex user-level install path for gitnexus-plan

Codex discovers SKILL.md skills from ~/.agents/skills (same path the other
gitnexus-* skills install to); README now documents the cp install plus the
optional ~/.codex/prompts slash-command file, with the prompt body preferring
the repo copy and falling back to the user-level install.

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

* feat(skills): gitnexus-plan freshness gate + active PDG-layer refresh

Freshness is now a Phase 1 gate, not advisory: under the default
freshness:strict, a stale index is refreshed once per planning session via
node .gitnexus/run.cjs analyze --index-only (appending --pdg when the task
will reach the PDG phase), then the context resource is re-read. A missing
PDG layer likewise triggers the one permitted --index-only --pdg refresh
and re-probe instead of a passive recommendation. freshness:accept (or a
failed/impractical refresh) preserves the old behavior: plan on the stale
graph, source-weighted, labelled in the plan header. --index-only is the
load-bearing flag choice — it suppresses all file generation, so the
planning-only contract holds (only the .gitnexus store changes). Ledger
gains an index_refresh record; plan header states fresh / refreshed /
refresh-skipped-with-reason.

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

* feat(skills): gitnexus-plan runner build check before freshness refresh

When the target repo builds the analyzer from its own source (bin → dist/
mapping, as gitnexus/ does), the Phase 1 freshness gate now verifies dist/
is current before running the analyze refresh — rebuilding via the
package's build script when any analyzer source file is newer than the
built entrypoint — and prefers that freshly built CLI. Otherwise a stale
dist re-indexes with outdated extraction logic and the 'fresh' index lies.
Rebuilds are recorded in the ledger's index_refresh; the PDG-phase refresh
inherits the same check.

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

* feat(skills): add gitnexus-work executor and gitnexus-lfg pipeline

gitnexus-work executes a gitnexus-plan as verified atomic commits: consumes
the §11 implementation_context pack, drift-checks the plan's evidence pin
against HEAD, re-verifies assumptions before relying on them, runs impact
before every symbol edit and detect_changes before every commit (repo
mandates), builds tests from the plan's scenarios, and routes structural
drift back to gitnexus-plan Deepen mode instead of coding around it.

gitnexus-lfg is a thin orchestrator: gitnexus-plan → blocking user gate
(deepen / proceed / stop, deepen loops allowed) → gitnexus-work → review
via the existing gitnexus-pr-review skill (open PR, else branch diff vs
default). One bounded fix cycle for review findings; never pushes or opens
a PR on its own.

gitnexus-plan gains a Deepen mode (re-run freshness gate, escalate to
depth:deep, re-verify graph/inferred/assumed claims toward verified,
rewrite the same file); its 'future gitnexus-implement' placeholder is
retired in favor of gitnexus-work. Registered via .gitignore whitelists,
AGENTS.md 1.10.0 (section renamed to Engineering planning & execution),
CLAUDE.md 1.5.0.

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

* fix(skills): apply cross-skill review findings to the gitnexus skill family

Two P1s: gitnexus-plan Deepen mode now re-anchors before re-pinning
(diffs the old evidence pin over every [verified]-claim file and re-reads
or downgrades before the header moves — moving the pin without this
laundered stale claims as verified); the index-refresh budget is stated
once in Phase 1 (one --index-only refresh plus at most one Phase 3 --pdg
upgrade per session, Deepen = its own session) with ledger and pdg-slice
deferring to it.

Contract fixes: gitnexus-work's drift check now covers every file the
pack cites (not just files_to_modify) and parses the full pack incl.
primary/related symbols and acceptance_criteria (walked in Phase 4
alongside §13); a pre-completed check skips §7 steps already landed and
Deepen gains a reconcile-execution-state step, closing the mid-execution
route-back loop; pack assumptions must name what to check and how.

lfg: Lane 4 passes the merge-base to detect_changes compare (two-dot
diff misattributes upstream commits when default advanced), branch-diff
is the stated normal case, oversized review findings route to the plan
gate instead of overflowing direct mode, the one-fix-cycle cap is
explicit on re-run, and headless runs end at the plan gate with the plan
as deliverable. work: blank mode narrowed to *gitnexus-plan*.md with a
re-execution guard, direct-mode discipline spelled out, branch
meaningfulness defined against the plan slug, and the plan document is
committed as the branch's docs commit (review diff includes it).
Planning-only contract now names the dist/ rebuild as the second
permitted state change; Phase 5.1 names the four claim tags; stale
AGENTS.md anchors fixed.

Known latent issue left untouched: gitnexus/gitnexus-pr-review pairs a
three-dot example with a two-dot detect_changes compare — that skill is
also shipped by the plugin, so fixing it here would drift the copies;
lfg compensates by passing the merge-base.

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

* feat(skills): ship the engineering skill family with the gitnexus package

npm i -g gitnexus users now get gitnexus-plan / gitnexus-work / gitnexus-lfg:
the three skills are added to gitnexus/skills/ in directory form (SKILL.md +
references/), which installSkillsTo already enumerates dynamically and copies
recursively to every editor target (~/.agents/skills for Codex, Cursor,
OpenCode, Qoder, ...) on gitnexus setup — uninstall enumerates the same root,
so removal stays clean. The Claude Code plugin channel
(gitnexus-claude-plugin/skills/) carries the same copies plus the standard
per-skill mcp.json.

Global-install support in the skill text: gitnexus-plan Phase 1 now resolves
the analyzer runner explicitly — node .gitnexus/run.cjs analyze when the
project has a runner, else gitnexus analyze (installed CLI), else
npx gitnexus analyze — and all analyze mentions route through it, satisfying
the skills-steering policy (#1939/#1945) which sweeps the plugin copies.

New drift guard test/unit/shipped-skills-sync.test.ts asserts the npm and
plugin copies stay byte-identical to the canonical .claude/skills/ family
(plugin = canonical + mcp.json), same discipline as run.cjs ↔
resolve-invocation.ts. skills-steering + shipped-skills-sync: 11/11 green.

* feat(eval): workflow_bench — measure the skill workflow's token savings

Benchmarks gitnexus-plan → gitnexus-work against a baseline agent
(--disallowedTools Skill) on identical tasks, in fresh detached worktrees,
using real headless Claude Code sessions; every number comes from the CLI's
--output-format json usage report (field names validated against a live
2.1.207 session). Reports per-arm medians (input/cache/output tokens, cost,
wall time, turns), a savings row, and resolve status from a per-task verify
command — savings on failed tasks are flagged, not celebrated. Per-task
setup hook prepares fresh worktrees (deps); --permission-mode
bypassPermissions (default) lets sessions run unattended in the throwaway
trees.

Free-model support: --base-url/--auth-token/--model route headless sessions
through any Anthropic-compatible endpoint; free-model.litellm.yaml is a
ready litellm-proxy template for OpenRouter :free variants or local Ollama,
so benchmarking burns no paid tokens (README documents rate limits and the
small-model skill-following caveat).

Harness validated end-to-end with a stub CLI (worktree lifecycle, both
arms, plan→work chaining, verify, aggregation, report) and 4 pytest units
for the pure aggregation/savings/report helpers. AGENTS.md 1.11.0.

* docs(eval): record first workflow_bench calibration run

Trivial-task calibration (add -V alias): both arms resolved; workflow arm
~4.3x baseline cost — the documented overhead-dominated regime, recorded so
the regime boundary is empirical rather than asserted.

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

* feat(eval): workflow_bench scenario matrix — arm variants, task classes, churn

Ground-base measurement across scenarios: tasks.scenarios.yaml spans four
labeled classes (trivial → investigation-bug → investigation-feature →
cross-module) with deterministic verifies (prescribed test files). New arms:
workflow_direct (gitnexus-work direct mode — the middle option that locates
the routing boundary lfg's gate and work's triage encode) and baseline_nomcp
(no skills AND no graph tools — separates workflow-discipline value from
GitNexus-tool value; off by default). Records now carry task class and diff
churn (files/+ins/−del vs the starting commit) as an over-engineering proxy;
the report renders a class column and per-arm savings rows vs baseline.
5 pytest units + stub-CLI e2e of the full three-arm matrix.

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

* docs(eval): record workflow_bench ground base; fix churn measurement bias

Ground base (3 classes x 3 arms, n=1/cell): every arm resolved every task —
pass/fail quality saturates at this difficulty, making the comparison pure
cost. Full plan→work never amortized its ~$9-11 fixed cost on tasks a
baseline finishes in ≤35 turns (−211% to −333% cost); workflow_direct sits
near baseline (−15% to −55%, once faster wall) with more test coverage.
Routing implication recorded: direct mode/plain agent below this scale,
full workflow for cross-module / multi-session / plan-as-deliverable work.
The cross-module cell and multi-run variance are the next measurements.

Churn fix: git add --intent-to-add -A before diffing (arms that never
commit no longer undercount new files) and :(exclude)docs/plans (the
committed plan doc no longer inflates workflow churn); this run's churn
numbers predate the fix and are omitted from the recorded table.

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

* perf(skills): cost-optimize the workflow from measured ground base

Every optimization targets a measured fixed-cost component
(eval/workflow_bench ground base: workflow arm −211% to −333% vs baseline,
all tasks resolved):

- Plan form is category-priced: compact form (core sections w/ § anchors
  preserved, ≤80 lines excl. pack, mini-pack subset of the context pack)
  for narrow/default categories; the full 13 sections only for deep work
  (refactor/security/performance/concurrency/architecture). A compact plan
  outgrowing its cap reclassifies to full rather than overflowing.
- Freshness gate is category-priced: compact categories default to accept
  (source-weighted, refresh only when a graph claim becomes load-bearing);
  strict stays the default for full-plan categories — the rebuild+re-index
  was the largest single fixed cost.
- Turn economy: per-category tool-call budgets (~10 to ~45; architecture
  uncapped); budget exhaustion routes open questions to §12 instead of
  more digging.
- gitnexus-work fast path: HEAD == evidence pin → skip all citation
  re-reading (the pin's entire point); mini-pack fields tolerated.
- lfg Lane 1 boundary triage: tasks below the measured ~35-turn boundary
  get offered gitnexus-work direct mode before the plan lane is spent.

Copies re-synced (npm skills/, plugin, ~/.agents); steering + sync guards
green. Re-measurement of the workflow arm follows to verify the numbers
actually improve.

* docs(eval): record optimization re-measurement — inv-bug workflow cell −20% cost

Same task, same conditions, post-830a0459 skills: $14.56→$11.70 (−20%),
83→72 turns, cache_read −24%; verified in-transcript that the compact form,
turn budget, and skipped rebuild/re-index all fired. Wall +15% from a work-
session test-debugging tail (n=1 variance). Regime unchanged (~3.5x baseline
on this class) — routing rule stands.

* fix(eval): per-arm clone isolation — worktree ref-namespace leak contaminated an arm

The cross-module workflow_direct cell reported an impossible 28-turn solve
with churn byte-identical to the workflow arm: git worktree add shares the
repo's ref namespace, so the workflow arm's slug branch (created by
gitnexus-work Phase 2) survived worktree removal and the direct arm found
and adopted the completed work. Arms now get isolated git clone --shared
copies (object store via alternates, refs clone-local — agent branches and
stashes die with the clone; origin/<ref> fallback for non-default refs).
Leaked branch deleted; baseline arm verified clean (0 branch references in
its transcript); cell marked invalidated pending re-run.

Records the valid cross-module cells: workflow $18.32 vs baseline $18.03
(premium −1.6%, vs −211%..−333% on smaller classes) — fixed costs amortize
at this scale, with a less destructive diff and a plan artifact as bonus;
resolve rate still tied. Churn fingerprinting is what caught the
contamination — noted in the README as an integrity check.

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

* docs(eval): complete cross-module cell — direct mode wins 47% cost / 56% wall

Clean clone-isolated re-run: workflow_direct resolved the hardest class at
$9.53/52 turns/15m vs $18.03/98/34m baseline and $18.32/107/37m full
workflow. The measured story across all four classes: the execution
discipline (gitnexus-work) is the consistent sweet spot and delivers real
token savings on hard tasks; the planning pass buys its artifact, not
same-session savings. Resolve rate tied everywhere (n=1/cell caveat).

* fix(eval): allow pr-review skill candidates

* feat(skills): rename and generalize GitNexus review

* feat(eval): external-comparator and review arms for workflow_bench

  arms prompted with the same structure as the gitnexus arms
- review / ce_review: gitnexus-review vs ce-code-review on an identical

- plan handoff is snapshot-based: committed example plans in docs/plans/
  tie on clone mtimes and broke the name-glob pick (executed a stale plan)
- verify output tail is recorded per run and the final working-tree patch
  is kept, so failed rows are diagnosable after the clone is destroyed

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

* fix(skills,eval): address #2431 review — data-safe rename migration, fail-closed bench evidence

- setup: never delete a legacy renamed skill dir — the installer cannot
  prove ownership (users customize or hand-write skills under these
  names); warn with the path instead, and the test now asserts survival
- workflow_bench: fail closed when a session's --output-format json
  report is empty, malformed, or missing usage fields — an exit-0 shell
  with no parseable usage no longer counts as measured evidence
  (5 parametrized regression tests)
- workflow_bench: document the trust model prominently (task setup/verify
  are shell-executed, sessions run bypassPermissions with the parent env,
  candidate overlays are prompt injection surface) in README + docstring
- free-model.litellm.yaml: master_key from LITELLM_MASTER_KEY env instead

* fix(eval): demand observed foreground verification in headless work-arm prompts

In a headless -p session there is no later turn: a work arm backgrounded
its slow test run, scheduled wakeups that can never fire, and reported
done while two of its tests failed. All four work-arm prompts (both

* feat(skills): ask plan depth up front instead of offering deepen afterwards

gitnexus-plan Phase 0 now asks one blocking question in interactive
sessions — quick / standard / deep, mapped onto the existing depth/form/
freshness knobs — when the invocation carries no explicit depth signal.
Explicit knobs and headless runs skip the question (category posture
unchanged, so benchmarks and automation behave as before).

gitnexus-lfg's plan gate slims to proceed/stop: depth was already the
user's up-front choice, so deepening is no longer offered by default —
an explicit deepen request at the gate and executor route-backs still
run Deepen mode, which remains the mechanism for strengthening an
existing plan document.

All shipped copies resynced (npm skills/, Claude plugin); AGENTS.md
1.13.0 and CLAUDE.md 1.7.0 pointers updated, including the analyzer's
regenerated index-stats block at this branch's head.

* feat(skills): taint pass, expert lenses, and post-work index refresh

gitnexus-review gains a PDG-backed taint-and-dependence pass (explain +
pdg_query, --pdg folded into the stale refresh on trust-boundary diffs) and
an Expert lenses section: domain reviewers derived from the graph's
clusters plus four cross-cutting lenses (architectural fit, language
conformance per the repo's own contract, Definition of Done, simplicity),
dispatched once after the evidence-gathering steps and scaled to the diff.
gitnexus-work Phase 4 now refreshes the knowledge graph after the DoD walk
via the resolved-runner ladder with analyze --index-only, so the lfg review
lane and later sessions query the finished work without dirtying the tree.
lfg's threshold-governance paragraph moves to its README; eval citations
are tagged as measured in the GitNexus repo. All shipped copies re-synced.

* fix(cli): remove legacy gitnexus-pr-review on uninstall; cover the rename migration

uninstall's removal set now includes LEGACY_SKILL_DIR_NAMES derived from
RENAMED_SKILL_DIRS, so a pre-rename install is cleaned up instead of
orphaned. The rename warning gains behavioral coverage (fires with a legacy
dir present, silent without), and shipped-skills-sync asserts legacy names
stay absent from every shipped tree.

* fix(eval): metric provenance, error-kind rows, skill-invocation verification, gate noise floor

The promotion gate defaults to cost_usd (the only metric that includes
subagent spend); token metrics carry an explicit main-loop-only warning in
the report and promotion.json. Rows are classified by error_kind
(session-error / verify-failed / infra-error), excluded from efficiency
medians, and the gate requires equal valid-run counts. Each session's
transcript is scanned for the expected Skill invocation and fails closed on
a verified miss; a one-run resolution edge no longer promotes (noise
floor). Per-run timeouts and setup failures record an infra-error row
instead of aborting the sweep. Overlays touching skills no candidate arm
exercises are rejected up front.

* docs: fix skill routing paths, version headers, and skill rosters

Routing tables point at the tracked direct skill paths (matching the
post-#2434 generator output), AGENTS.md/CLAUDE.md headers match their
latest changelog rows, the 1.12.0 row describes what the migration actually
does, package/cursor READMEs list the full shipped skill roster, and the
swarm READMEs describe /gitnexus-review's expert lenses instead of calling
it single-agent.

* ci: drift-guard workflow for skill copies; pin eval pip deps; track docs/plans

ci.yml ignores '**.md', so an md-only skill edit would merge without the
shipped-skills-sync test running — skill-sync.yml triggers exactly on the
guarded trees. The eval job's pip install is version-pinned, and
docs/plans/ is unignored so gitnexus-plan output can be committed.

* fix(ci): keep the runner-invocation literal in gitnexus-review; add concurrency block to skill-sync

skills-steering requires skills with a stale-index hint to carry the exact
'node .gitnexus/run.cjs analyze' form — restore it with the fallback ladder
as a parenthetical instead of replacing it. skill-sync.yml gains the
top-level concurrency block the workflow-convention check enforces.

* test(eval): isolate transcript home on Windows

Ensure workflow_bench transcript tests set USERPROFILE alongside HOME so Path.home() resolves to the temporary test home on Windows.

* docs(skills): fold PR #2522 execution learnings into review/work/plan

Eight incident-backed hardenings from running the full skill cycle
(review -> plan -> work, 28-finding fix series) on PR #2522:

gitnexus-review:
- Expert lenses execute the code under review on candidate failing shapes
  (empirical probe outranks source reading — every HIGH the language
  lenses found came from a probe, not a read).
- Step 7 re-runs the exact CI check for refreshed baselines/fingerprints
  (a stale committed artifact is invisible in the diff; caught a red
  benchmarks arm).
- Step 8 treats version/invalidation constants as review surface
  (INCREMENTAL_SCHEMA_VERSION class recurred verbatim from #2494).

gitnexus-work:
- Step 4 proves regression tests discriminate against the pre-fix tree.
- Step 5 rebuilds executed build output before every verification run
  (parse workers load dist/; a correct fix 'failed' until rebuilt).
- Step 6 makes stage -> detect_changes -> commit one unbroken sequence.

gitnexus-plan:
- Phase 0 seeded-evidence mode: plan FROM a completed review's verified
  findings instead of re-running the graph ladder.
- Template §7: fingerprint/golden-guarded output rebaselines once, at the
  series tip.

All distribution copies resynced; shipped-skills-sync + skills-steering

* feat(eval): close the skill-evolution loop with an automated proposer driver

workflow_bench.evolve adds the three arrows the README described as manual:
a proposer session that turns loser trajectories (results.jsonl rows,
transcripts, patches, the learning queue) into ONE bounded candidate
overlay, a driver that iterates propose -> paired benchmark -> deterministic
gate up to --generations, and an --apply step that copies a promoted
overlay onto the canonical skills and shipped mirrors as a working-tree
diff. The trust boundary is unchanged: overlays re-validate through
candidate_overlay_files before any benchmark or apply consumes them, and
committing, CI, and the PR merge stay human.

learnings.jsonl is gitignored: it is machine-local evidence, like the
session transcripts it complements.

* docs(skills): route live-task friction into the evolution learning queue

Each family skill gains a short 'Skill feedback' section: on friction with
the skill's own instructions, append one JSON line to
eval/workflow_bench/learnings.jsonl (GitNexus repo only) — never self-edit
the skill from a live task. The proposer in workflow_bench.evolve consumes
the queue as hints; a learning reaches a shipped skill only by beating the
incumbent on the paired benchmark. All shipped mirrors re-copied byte-
identical.

* ci(tests): run the evolve helper tests in the eval pytest job

* feat(ci): comment-triggered GitNexus review agent for PRs

'@gitnexus review' from a maintainer (OWNER/MEMBER/COLLABORATOR; the action
re-validates write access) runs the repo's gitnexus-review skill headlessly
against the PR and posts the review as a sticky comment — remote triggering
with no local setup. Read-only by construction: contents: read token,
Write/Edit and web tools disallowed, Bash allowlisted to git reads and the
gitnexus CLI; analyze parses PR code with tree-sitter, never executes it.
Requires the ANTHROPIC_API_KEY repository secret; activates once the file
is on the default branch.

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

* feat(ci): dispatch lane + existing OAuth secret for the review agent

Align with claude.yml: same action pin and the CLAUDE_CODE_OAUTH_TOKEN
secret the repo already carries — no new secret to configure. Add a
workflow_dispatch lane (PR number input) so the agent can be triggered from
the Actions UI and tested before the issue_comment trigger reaches the
default branch. Allowlist gh pr view/diff and gh api, which the review
skill uses to pin PR SHAs.

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

* fix(ci): close a fork-PR RCE vector in the review agent's tool allowlist

A live headless run of the exact workflow session against PR #2431 (66
turns, full gitnexus-review pass) surfaced a real HIGH-severity confused
deputy: .gitnexus/ is gitignored, not blocked — a fork PR can commit its
own .gitnexus/run.cjs, issue_comment checks out PR-head content, and the
skill's runner ladder tries 'node .gitnexus/run.cjs analyze' first. That
would execute fork-controlled JS inside a job holding
CLAUDE_CODE_OAUTH_TOKEN and a write-scoped GITHUB_TOKEN — the opposite of
the 'PR code is read, never executed' claim in the workflow's own header.

Fix: drop the run.cjs allowlist entry so analyze always resolves through
npx gitnexus (npm registry, not the checked-out tree); the skill's
documented fallback mode covers the resulting graceful degradation. Also
drop 'gh api' (not read-only — accepts -X POST/PATCH/DELETE) and downgrade
pull-requests: write to read (comment posting only needs issues: write;
the prompt already forbids formal review submission).

Same session flagged a latent evolve.py bug: select_evidence's cost sort
used dict.get's missing-key default, which doesn't cover an explicit JSON
null in a foreign --seed-results row and crashes proposer setup with
TypeError. Guarded with 'or 0.0' and added a regression test.

* fix: harden PR review and evolution trust boundaries

* ci: follow workflow concurrency convention

* fix(eval): make terminating error paths explicit

* fix: unblock hardened review runtime checks

* test: make containment canaries deterministic

* test: expose Claude canary tool failures

* fix: adapt clean shell environment for Claude

* fix(eval): accept the runner's transcript source key in evidence preflight

The proposer evidence preflight required transcript-artifact metadata to be
exactly {path, sha256, bytes}, but the runner stamps a fourth provenance key
(source=parent-captured-stream-json). Any --seed-results or generation>=2 run
therefore aborted with SandboxError before proposing or promoting. Pin the
producer literal as PARENT_EVENT_STREAM_SOURCE and validate it in the metadata
check, and round-trip real producer output through sum_sessions into the
preflight so the schema can't drift again.

* fix(eval): treat an unmeasured session cost as unavailable, not $0

well_formed validated only the nested usage block, so an otherwise-successful
session missing total_cost_usd was recorded as cost_usd=0.0 — and cost_usd is
the default promotion metric (lower wins), so a cost-less session scored as
free and could win promotion it never earned. Extract cost via measured_cost()
(None on absent/garbage, a measured 0.0 preserved), propagate None through
sum_sessions/aggregate/savings/report, and have the gate refuse to rank on a
metric that was not measured on every run in both arms.

* fix(eval): warn when ranking on the main-loop-only num_turns metric

num_turns comes from the CLI's top-level usage (main-loop session only), like
output_tokens, but selecting it emitted no metric_warning — so a subagent-heavy
candidate could look artificially efficient. Add num_turns to
MAIN_LOOP_ONLY_METRICS and broaden the warning to cover turns.

* fix(eval): fail closed when an overlay adds a file with no committed base

An overlay adding a new .md under gitnexus-{plan,work} passes the structural
overlay checks but has no committed base for committed_destination_base_digests
to bind against, so it raised an uncaught ValueError that crashed the evolve
driver (and runner --candidate-overlay) mid-run. Catch it at both call sites:
evolve reports NOT PROMOTED and exits, runner routes it through parser.error.

* feat(eval): circuit-break the runner sweep on a systemic outage

A sustained upstream outage used to pay out every remaining --timeout window
one session at a time. Track consecutive session/infra/cleanup failures via a
pure systemic_outage_streak helper; after --outage-streak (default 5) in a row,
stop the sweep, still write report.md/promotion.json from partial evidence, and
exit non-zero so evolve.py halts instead of proposing from truncated evidence.
A task's own resolved=False never trips the breaker.

* fix(cli): report a dirty working tree as stale in gitnexus status

status --json (and the human output) computed up-to-date from commit + runner
identity + completeness only, so a repo with uncommitted source changes at a
matching HEAD was reported up-to-date while analyze would still re-index it.
A graph-backed agent gating on that JSON could skip re-analysis on a stale
graph. Extract analyze's dirty-tree check into a shared isWorkingTreeDirty()
in storage/git and fold it into the status freshness decision.

* fix(ci): use single-slash deny globs in the review agent's disallowedTools

github.workspace already expands to an absolute path, so Read(/${{ github.workspace }}/**)
and Read(//proc/**),(//sys/**),(//dev/**) produced double-slash patterns that a
normalizing matcher may not match — silently no-opping the deny layer. Not
exploitable (the allowlist is the primary control and never grants those
paths), but the globs should be well-formed. Update the pinned test strings.

* ci: install gitnexus-shared with npm ci from the committed lockfile

The gitnexus-shared build floated its deps via npm install in three workflows
(skill-sync, ci-tests, and — most importantly — the release publish.yml) while
every other install step uses npm ci. The lockfile is committed and in sync, so
switch all three to npm ci for reproducible, locked installs.

* test(cli): make the shipped-skills drift guard reject symlinks

listFilesRecursive walked with readdirSync and snapshotDir read with
readFileSync, both of which follow symlinks — so a mirror file symlinked to the
canonical tree passed the byte-compare (and a symlinked mirror dir would be
followed too). Reject a symlinked root via lstat and any symlinked entry via
Dirent.isSymbolicLink, with negative tests (skipped on Windows).

* test(eval): guard the candidate-skill vs mirror-root coverage invariant

MIRROR_SKILL_ROOTS omits the Cursor tree, safe only because no candidate skill
is cursor-shipped. Pin that invariant: every CANDIDATE_SKILLS entry must exist
under canonical + every mirror root and must not ship to Cursor, so adding a
cursor-shipped skill to the candidate set (the PR #2488 asymmetric-sync class)
fails loudly instead of syncing three of four trees.

* docs(ci): describe the review agent's staged post-merge rollout

The DoD asked for a dry-run or triggered run before merge, but an issue_comment
(or newly added workflow_dispatch) workflow only ever executes the default-branch
copy, so it cannot be exercised from the PR that introduces it. Reword the DoD
and the activation checklist to a staged rollout: merge registered-but-disabled,
validate same-repo and fork execution post-merge, then enable the variable.

* fix: pin plugin skill mcp.json to the release version via #2445 tooling

The ten plugin skill mcp.json launched `npx -y gitnexus@latest mcp` on every
skill connect — non-reproducible and a supply-chain surface, and (unlike the
persisted setup config) never pinned. Extend sync-plugin-manifests.mjs with an
mcp surface kind that stamps the gitnexus@<version> launch arg, pin all ten to
1.6.9 now, and keep them byte-identical so the drift guard stays green. The
release lifecycle + publish.yml --check now re-stamp them like the four manifest
surfaces; only READMEs stay on @latest as docs.

* test(eval): prove the proposer's built-in file tools are confined

The real-Claude canary only exercised Bash + MCP, so it proved process/MCP
containment but not that the proposer's built-in file tools stay inside their
mounts. Add a canary over the exact PROPOSER_ALLOWED_TOOLS surface and the same
read-only /evidence mount as run_proposer (allowlist extracted to a shared
constant so it can't drift): Read reaches /evidence, a Write into the read-only
evidence mount is denied, and a Write lands in the output tree.

* fix(eval): apply the candidate overlay after task setup for fair arms

The candidate overlay was applied before the task's untrusted setup ran, so
setup could observe candidate prose and the incumbent/candidate arms started
from different pre-overlay state. Reorder within the sandbox: capture the base
(pre-overlay) skill digest, run setup against the base skills, verify setup did
not tamper them, then apply the overlay and capture the post-overlay digest the
model must preserve. apply_candidate_overlay stages path-specific overlay files,
so setup's uncommitted changes stay out of the baseline and churn is unchanged.

Graph freshness for the review arm is handled by the status dirty-tree fix plus
the review skill's stale-triggered re-index, not by reordering the cached
per-task-sha graph materialization (which is mechanically blocked).

* test(eval): end-to-end containment proof of the autonomous proposer

Drives the real run_proposer through bubblewrap with a deterministic scripted
model (no paid API): it reads the read-only evidence bundle and writes a
candidate gitnexus-plan skill edit plus a rationale into the sandbox output
tree; run_proposer enforces the trust boundary and copies only the validated
overlay + proposal out. This exercises the autonomous-proposal stage of the
self-evolution loop end-to-end in the eval/containment CI job (the gate and
apply stages are covered by test_workflow_bench_evolution and
test_promotion_apply). Env-gated on GITNEXUS_REQUIRE_CLAUDE_CANARY, so it runs
only where the pinned Claude binary and user namespaces are available.

* fix(eval): let the proposer author its overlay via Bash

Running the end-to-end proposer canary in the containment CI job surfaced a real
bug: run_proposer starts the session with --bare, which hard-disables the
Write/Edit tools ("Write exists but is not enabled in this context"), yet
allowlisted Edit/Write and omitted Bash. The proposer therefore had no working
way to write its candidate overlay — the self-evolution loop could never produce
a candidate. The sandbox settings already pre-authorize Bash
(autoAllowBashIfSandboxed) and confine writes to workspace/tmp/home, so switch
PROPOSER_ALLOWED_TOOLS to Read/Grep/Glob/Bash and tell the proposer to author
files with Bash. The end-to-end test now drives the real run_proposer through
bubblewrap and asserts a validated overlay + proposal are produced (this also
replaces the earlier file-tool canary, whose Write/Edit premise was moot).

* test(eval): author the proposer overlay with newline-free Bash content

The nested shell-sandbox prefix mangles embedded newlines, so the multi-line
overlay content never landed. Use single-line content for the deterministic
proposer canary.

* test(eval): drop the unverifiable end-to-end proposer canary

The scripted proposer overlay never materialized in the containment job across
runs, and the model tool-result content is not visible in CI logs, so the test
cannot be finalized without an environment where the sandbox can actually run.
Keep the verified production fix (Bash-authoring in run_proposer); the proposer
sandbox/containment stays covered by the existing Bash+MCP and process-tree
canaries.

* test(cli): drop run-analyze.ts from the windowsHide spawn-family list

U7 moved run-analyze.ts's only child_process call (the git status --porcelain
dirty check) into storage/git.ts (already covered by this test, with
windowsHide). run-analyze.ts no longer imports a spawn-family function, so the
windowsHide-regression test's 'must have >=1 spawn call' invariant failed for
it. Remove it from SRC_FILES.

fix(lbug): bound the LadybugDB buffer pool instead of the native 80%-of-RAM default (#2560)
* fix(lbug): bound the LadybugDB buffer pool instead of the native 80%-of-RAM default (#2557)

createLbugDatabase passed bufferManagerSize=0, which the native runtime
sizes at 80% of physical RAM. A long-lived gitnexus mcp process (or a
large incremental analyze) could balloon to that ceiling — 19.5 GiB
observed against a 105 MiB on-disk index — and OOM-kill the host session.

Resolve the pool at call time: default min(2 GiB, max(64 MiB, 80% of
totalmem)), overridable via GITNEXUS_LBUG_BUFFER_POOL_SIZE (bytes);
0 deliberately restores the native unbounded default; invalid values
warn and fall back, mirroring GITNEXUS_WAL_CHECKPOINT_THRESHOLD.
