Subject: [PATCH 01/40] fix(typescript): capture missed CALLS edges from HOF
 callbacks and JSX

Two distinct gaps in the TypeScript scope-resolution path were silently
dropping call edges in real-world React + TanStack + Zustand codebases.
On the bug reporter's repo (Sourcerer-fe, 1185 src/ functions), 504
missing Function->Function CALLS edges are now captured (+61.6%) and
the no-outgoing-CALLS orphan rate drops from 73.2% to 60.3%.

HOF / arrow-callback caller-attribution (3 cooperating fixes):
  - typescript/query.ts: @declaration.function anchor moved from the
    wrapping lexical_declaration to the inner arrow_function /
    function_expression, so anchor.range aligns with @scope.function and
    pass2AttachDeclarations lands the def on the arrow's own scope.
  - finalize-algorithm.ts: findExportByName prefers callable / class-
    like defs over Variable when localDefs contains both for the same
    name (TS emits two defs per `const fn = () => {}`).
  - graph-bridge/ids.ts: resolveCallerGraphId's walk-up class-fallback
    now uses isCallerAnchorLabel restricted to Function / Method /
    Constructor / Class / Interface / Struct / Enum, so module-level
    calls fall through to the File node instead of mis-attributing to
    sibling Variable defs (the Zustand `create()(devtools(...))`
    phantom-self-loop regression).

JSX as a CALLS edge (2 cooperating fixes):
  - typescript/query.ts: new TSX_JSX_QUERY_SUFFIX (TSX-grammar only)
    captures jsx_self_closing_element / jsx_opening_element as
    @reference.call.free / @reference.call.member. PascalCase predicate
    filters native HTML elements (<div>, <span>) so they don't emit
    edges to nonexistent targets.
  - typescript/captures.ts: shouldEmitReadMember extended with
    jsx_self_closing_element / jsx_opening_element parent cases to
    suppress phantom ACCESSES edges on member-form JSX names.

Tests: 8 HOF assertions + 7 JSX assertions across two new integration
test files plus 13 minimal fixtures. typescript.test.ts (236),
api-deep-flow.test.ts (11), and scope-resolution / scope-extractor unit
tests (613) pass with no regressions.

+/**
+ * TypeScript: CALLS edges from inside higher-order-function callbacks.
+ *
+ * Repro for the bug filed in `gitnexus-bug-report.md`: in a real
+ * TS+React monorepo, ~75% of `Function` nodes had no outgoing CALLS
+ * edges. The dominant pattern was call expressions nested inside
+ * callbacks passed as arguments to other functions:
+ *
+ *   - `Promise.all(items.map(item => transform(item)))`
+ *   - `useQuery({ queryFn: () => fetchData() })`
+ *   - `new Promise((resolve) => { reader.readAsDataURL(file); ... })`
+ *   - `create<State>()(devtools(persist((set) => ({ ... }))))` (Zustand)
+ *
+ * Two underlying issues fixed by this PR (see `query.ts` and
+ * `finalize-algorithm.ts`):
+ *
+ *   1. **Caller attribution.** `pass2AttachDeclarations` placed the
+ *      `Function` def for arrow-typed declarations on the wrapping
+ *      module scope (the `@declaration.function` anchor was the outer
+ *      `lexical_declaration`, whose start lies before the inner
+ *      arrow's scope). `resolveCallerGraphId` walked up past the empty
+ *      arrow scope into the module and grabbed the first Function-like
+ *      def in `ownedDefs` — frequently the wrong function entirely.
+ *
+ *   2. **Cross-file callee discovery.** TypeScript emits BOTH
+ *      `@declaration.function` (Function def) AND `@declaration.variable`
+ *      (Variable def) for `const fn = () => {}`. With (1) fixed, the
+ *      Function-def's anchor moved to the inner arrow, so the Variable
+ *      capture began appearing FIRST in `localDefs` (its match starts
+ *      earlier in the source). `findExportByName` returned the
+ *      Variable, the consumer's import bound to a non-callable, and
+ *      `findCallableBindingInScope` rejected it.
+ *
+ * Each test fixture below isolates one HOF-callback shape from the bug
+ * report with both caller and callee defined in-fixture.

Subject: [PATCH 02/40] fix(ts): attribute calls inside HOF/callback patterns
 to the right function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two roots in `findEnclosingFunctionId` (parse-worker) and the parallel
`findEnclosingFunction` (call-processor):

A. `genericFuncName` scanned `arrow_function` / `function_expression`
   children for the first identifier and returned it. For unparenthesized
   arrows like `file => processFile(file)` the first identifier is the
   parameter `file`, so calls inside got attributed to a phantom
   `Function file` ID and emitted dangling CALLS edges that never showed
   up in `(:Function)-[:CALLS]->()` queries.

B. `tsExtractFunctionName` only named arrows whose parent was
   `variable_declarator`. Object-property arrows like
   `addItem: (item) => set(...)` (Zustand stores, TanStack queryFn,
   React Context providers, config objects) live under a `pair`, so they
   were treated as anonymous. With no named ancestor up to the file,
   every call inside fell back to the File and became invisible to
   `context()` / `impact()`.

Fix:
- `genericFuncName` returns null for anonymous JS/TS function-likes —
  the language hook is authoritative.
- `tsExtractFunctionName` resolves names from `pair` parents
  (property_identifier / string keys; computed keys stay anonymous).
- Mirror the new shape in `TYPESCRIPT_QUERIES` / `JAVASCRIPT_QUERIES` /
  the scope-resolution query so pair-with-arrow becomes a Function
  declaration node — call sourceIds resolve to a real graph node.

Adds 18 unit tests pinning attribution and definition behaviour for
plain helpers, `arr.map(x => fn(x))`, Promise constructor callbacks,
Zustand-style nested HOFs, TanStack query factories, string-keyed
pairs, and computed-key anonymity.

Fixes #1166

+ * (call-processor.ts):
+ *
+ *     const efnResult = provider.methodExtractor?.extractFunctionName?.(current);

+ *     arrows like `file => processFile(file)` the first identifier is the
+ *     parameter `file`, so calls inside got attributed to a phantom
+ *     `Function file` ID. The CALLS edges were emitted with a dangling
+ *     sourceId and never showed up in `(:Function)-[:CALLS]->()` queries.
+ *
+ *  B. `tsExtractFunctionName` only named arrows whose parent was
+ *     `variable_declarator`. Object-property arrows like
+ *     `addItem: (item) => set(...)` (Zustand / TanStack / config objects)
+ *     have a `pair` parent and were treated as anonymous. With no named
+ *     ancestor up to the file, every call inside fell back to the File ID.
+ *
+ * These tests pin attribution behavior for both root causes and the common

Addresses the automated review findings on PR #1175:

- prettier --write the 3 files flagged by `quality / format` CI check
  (query.ts, typescript-hof-callbacks.test.ts, typescript-jsx-as-call.test.ts).

- [medium] typescript-jsx-as-call.test.ts: tighten the combined HOF+JSX
  assertion from `toBeGreaterThan(0)` to `toHaveLength(1)`. A single
  `<Foo />` is one logical invocation; the bounds-only assertion would
  have masked a duplicate-CALLS-edge regression (e.g. if both
  `jsx_self_closing_element` and a generic call pattern matched the
  same site).

- [medium] typescript-hof-callbacks.test.ts: replace the vacuously-true
  `for (c of calls) expect(...)` Zustand assertion with a structural
  one. Old form passed unconditionally when `calls` was empty (any
  change that silenced ALL CALLS edges from store.ts would have
  slipped through). New form asserts both: (a) at least one File-rooted
  edge exists (proving the `isCallerAnchorLabel` fallback fires), and
  (b) no edge sources from anything else (proving the fallback fires
  exclusively).

- [low] finalize-algorithm.ts (`findExportByName`): rephrase the
  comment to make the language-agnostic nature of the tie-break rule
  explicit. The implementation was already correct for all migrated
  languages; only the comment overplayed the TypeScript specificity.

- [low] captures.ts (arity synthesis): add a comment explaining why
  JSX call anchors (`jsx_self_closing_element` / `jsx_opening_element`)
  intentionally don't synthesize `@reference.arity`. Name-only
  resolution is correct for React (components aren't overloaded in the
  current graph model); a JSX-aware synthesizer counting jsx_attribute
  children would be needed if that ever changes.

No production behavior change. All 8/8 HOF + 7/7 JSX + 236/236
typescript + 11/11 api-deep-flow integration tests still pass.
gitnexus and gitnexus-shared typechecks clean.

Subject: [PATCH 11/40] style(typescript): fix prettier formatting in
 tsExtractFunctionName

Single line-length fix in `gitnexus/src/core/ingestion/languages/typescript.ts`
flagged by `quality / format` CI on commit ef96603f. The unformatted block came
from the merge of upstream PR #1179 (`fix/issue-1166-calls-edges`) where the
`pair`-with-arrow / `pair`-with-string-key handling was added; prettier wanted
the `.find` callback inlined onto a single line.

No behavior change. Pre-commit hook would have caught this locally if the
husky postinstall step had been able to write `.git/config` on this dev machine.

the four `pair`-with-arrow patterns in `query.ts` anchored
`@declaration.function` on the outer `pair` node instead of the inner
`arrow_function` / `function_expression`. For multi-action object literals
like Zustand's

    persist((set) => ({
      addItem:    (item) => doA(item),
      removeItem: (item) => doB(item),
      fetchData:  ()     => doC(),
    }))

`pass2AttachDeclarations.atPosition(pair.startLine, pair.startCol)`
resolved to the *parent* `(set) => ({...})` callback's scope (because the
pair node starts at the property-key token, before the inner arrow's
`@scope.function` range). All three pair-function defs landed in the
same parent's `ownedDefs`, and `resolveCallerGraphId.ownedDefs.find(...)`
returned the FIRST one — `addItem` — for every walk-up. Calls inside
`removeItem` and `fetchData` mis-attributed to `addItem`; those two
functions had zero outgoing CALLS edges in the registry-primary path.

Single-pair fixtures (`bump` in `store.ts`, `queryFn` in `query-hook.ts`)
masked the defect because there is no ambiguity when only one
Function-like def lives in the parent's `ownedDefs` — `find()` is
deterministic over a single-element set.

Fix: move the `@declaration.function` anchor from the outer `pair` to
the inner `arrow_function` / `function_expression`, mirroring the
`lexical_declaration` patterns above (`const fn = () => {}`). The def
then lands in the arrow's own scope's `ownedDefs`, the
`rangesEqual(anchor.range, innermost.range)` auto-hoist promotes the
binding to the parent scope (so importers + lookups still find the name
in the surrounding scope), and each pair-arrow becomes an independent
caller anchor in the walk.

Tests:

  * Updated `useFeature → fetchData` expectation to `queryFn → fetchData`
    in `typescript-hof-callbacks.test.ts`. The new attribution is
    structurally correct: `fetchData()` is called from inside the named
    pair-arrow `queryFn: () => fetchData()`. The pre-fix expectation
    only worked because the pair-pattern bug rerouted the walk past the
    syntactic owner.

  * Added `multi-action-store.ts` fixture with three pair-arrows
    (`addItem` / `removeItem` / `fetchData`) plus three top-level call
    targets (`doA` / `doB` / `doC`). Four new tests pin per-action
    attribution: positive (each action calls its own target), negative
    (no sibling leakage), exact-set (the full pair set is what we
    expect), and the regression fingerprint (`addItem → doB` MUST be
    empty).

Validation:

  * `REGISTRY_PRIMARY_TYPESCRIPT=1 vitest run` on
    typescript-hof-callbacks (12 tests, +4 new), typescript-jsx-as-call
    (7), typescript (236), typescript-finalize, typescript-cross-file-imports,
    call-attribution-issue-1166 (18), all scope-resolution unit suites:
    886/886 pass on registry-primary AND legacy DAG paths.
  * Legacy DAG attribution was already correct via @abhigyanpatwari's
    `tsExtractFunctionName` pair-parent handling (#1179, merged into this
    PR earlier); this fix brings the registry-primary path to the same
    behavior, restoring parity for multi-action objects.
  * `npx prettier --check .`, `tsc --noEmit`, and `eslint` clean on the
    three modified/added files.

Subject: [PATCH 13/40] fix(deps): upgrade @ladybugdb/core to 0.16.0 to resolve
 native segfaults (#1235)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(deps): upgrade @ladybugdb/core to 0.16.0 to resolve native segfaults

Resolves the SIGSEGV / access-violation (0xC0000005) / exit-139 crashes that
have been reported widely since 1.6.3. The native crashes originate in
@ladybugdb/core 0.15.x — primarily during FTS index creation, VECTOR
extension load, and concurrent query teardown — and are reproducible on
Linux, macOS and Windows. The maintainer-confirmed fix is to bump the
runtime to 0.16.0, which ships nodejs async + memory-management fixes,
extension ABI bump, and macOS Intel binaries.

Adopting 0.16.0 cleanly required three supporting changes; without them
the upgrade itself regresses other paths:

1. maxDBSize must be passed explicitly. 0.16.0 keeps the upstream JSDoc
   note that the default 0 is "introduced temporarily for now to get
   around with the default 8 TB mmap address space limit some
   environment". Constrained CI runners and laptops cannot reserve 8 TB
   and crash with "Buffer manager exception: Mmap for size
   8796093022208 failed." A new gitnexus/src/core/lbug/lbug-config.ts
   centralises a 16 GiB default (overridable via
   GITNEXUS_LBUG_MAX_DB_SIZE) and every Database() construction site
   now passes it.

2. enableCompression default flipped from false to true in 0.16.0. Every
   Database() call site is updated to pass false explicitly so existing
   GitNexus indexes keep the same wire format.

3. Bridge DB sidecar files (.wal, .shadow). 0.16.0 enforces a database-id
   check on .wal / .shadow sidecars and rejects opens whose sidecars
   belong to a different base name. writeBridge now (a) cleans the full
   sidecar set when removing the tmp slot, (b) renames .wal / .shadow
   alongside the main file during the atomic .tmp -> .lbug swap, and
   (c) wraps openBridgeDbReadOnly in a bounded retry on transient
   Win32-Error-33 lock errors. Eager db.init() / conn.init() forces the
   lazy native handle to surface lock contention at the retry site.

Known limitation (not a regression): on Windows the 0.16.0 native binary
does not release the OS file lock until the process exits, so the
close-then-reopen-same-process pattern raises Error 33 after the first
close. Production paths (analyze / serve / mcp each open the DB exactly
once per process) are unaffected, but eight tests that exercise the
pattern are guarded with a process.platform === 'win32' skip; CI's
Linux + macOS shards exercise them as before. Tracking upstream:
kuzudb/kuzu#3872 / #3883 / #4730.

Closes #1136 #1154 #1160 #1162 #1178 #1195 #1196 #1199 #1204 #1206
Refs #1209 (supersedes — Dependabot bump without the supporting fixes)

Made-with: Cursor

* fix(test): isolate LadybugDB native test state

Use per-suite LadybugDB databases in integration helpers so test forks do not reopen a database created by Vitest global setup, and centralize Windows-tolerant native temp cleanup for bridge tests.

* fix(lbug): avoid bridge existence reopen

Reuse the built LadybugDB config in the extension installer and avoid native close/reopen cycles when checking bridge existence on Windows.

Made-with: Cursor

* chore(docs): exclude local lbug plan

Keep the refactor planning note out of the PR while leaving the ignored local copy on disk.

Made-with: Cursor

* refactor(lbug): centralize database construction

Route LadybugDB opens through shared helpers so native constructor defaults stay consistent across core, pool, bridge, and extension install paths.

+ * Shared configuration for `@ladybugdb/core` `Database` construction.
+ *
+ * Two values changed meaningfully in `@ladybugdb/core` 0.16.0 and need to be
+ * pinned explicitly by every caller, otherwise GitNexus regresses:
+ *
+ * 1. `maxDBSize` defaults to `0`, which the native runtime interprets as
+ *    "use the platform's full mmap address space" — typically 8 TB on
+ *    64-bit Linux. Constrained environments (CI runners, containers, WSL)
+ *    cannot reserve that much address space and crash with
+ *    `Buffer manager exception: Mmap for size 8796093022208 failed.`
+ *    See LadybugDB upstream JSDoc:
+ *    > "introduced temporarily for now to get around with the default 8TB
+ *    > mmap address space limit some environment".
+ *
+ * 2. `enableCompression` flipped its default from `false` (0.15.x) to
+ *    `true` (0.16.0). Existing call sites that relied on the positional
+ *    default must now pass `false` explicitly to preserve behaviour.
+ *
+ * Putting both in one shared module guarantees every `new lbug.Database(...)`
+ * call site agrees on the same ceiling and behaviour.
+ */

+ * remaining far below any 64-bit OS mmap ceiling.

Subject: [PATCH 14/40] fix(hook): resolve canonical repo root + guard
 read-only FTS ensure (#1226)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(hook): resolve canonical repo root + guard read-only FTS ensure (#1224)

Two bugs in the Claude Code hook + query layer integration:

1. `findGitNexusDir` (in `gitnexus/hooks/claude/gitnexus-hook.cjs` and
   `gitnexus-claude-plugin/hooks/gitnexus-hook.js`) walked upward from
   cwd looking for a non-registry `.gitnexus/`. In linked git worktrees
   created via `git worktree add`, the canonical repo's `.gitnexus/`
   never sits above the worktree path, so the walk silently fails and
   neither augmentation nor staleness notifications fire.

   Fix: keep the cwd-walk as the fast path, then fall back to
   `git rev-parse --git-common-dir` to resolve the shared `.git/`
   directory (which lives inside the canonical repo across all linked
   worktrees) and walk up from its parent. Returns null cleanly when
   `git` isn't on PATH or cwd isn't inside any working tree.

2. `ensureFTSIndex` in the LadybugDB adapter rethrew when the active
   connection is read-only (e.g. the MCP query pool, which opens DBs
   read-only by design). Defensive callers used to surface five
   "Cannot execute write operations in a read-only database" warnings
   per query.

   Fix: extract `isReadOnlyDbError` (mirroring the existing
   `isDbBusyError` discriminator) and have `ensureFTSIndex` catch the
   read-only error, cache the key, and return silently. Index creation
   is owned by `gitnexus analyze` on a writable connection — the
   ensure call is safely a no-op on the read pool. Lock / busy /
   "already exists" / schema errors continue to propagate.

Tests:
- `test/unit/hooks.test.ts`: new "Linked git worktree resolution"
  block exercises both hooks against a real linked worktree to confirm
  PostToolUse stale notifications fire, plus a negative case when the
  canonical repo has no `.gitnexus/`.
- `test/unit/lbug-readonly-error.test.ts`: new file unit-tests the
  `isReadOnlyDbError` discriminator (positive matches, case
  insensitivity, non-Error inputs, and unrelated errors that must
  still surface — lock contention, "already exists", schema misses).
- `test/integration/lbug-core-adapter.test.ts`: extends the existing
  FTS coverage with an idempotency assertion for `ensureFTSIndex` to
  pin the read-only guard's success-path contract.

Verified with `npx tsc --noEmit` and `vitest run` on the affected
files (hooks + readonly + lbug-core-adapter + bm25-search +
lbug-extension-loader + lbug-embedding-hashes — 136 tests pass).
Build: `npm run build` succeeds.

Closes #1224

* fix(local-backend): cover supported vector path

Add the supported-platform regression assertion for QUERY_VECTOR_INDEX and align the unsupported VECTOR diagnostic wording with platform policy.

Made-with: Cursor

Subject: [PATCH 16/40] fix(ingestion): index Python repos with empty
 __init__.py and >32 KB files (#1163)

* fix(ingestion): index Python repos with empty __init__.py and >32 KB files

Two defensive fixes that let `gitnexus analyze` complete on Python
codebases that previously failed.

scope-extractor: synthesize an empty Module scope when the provider
emits zero captures. Previously threw "no Module scope found", which
fired for any 0-byte `__init__.py` package marker if the bridge's
empty-source guard was bypassed.

python/captures: wrap the parser.parse() and getPythonScopeQuery()
.matches() calls in try/catch. node-tree-sitter throws "Invalid
argument" for sources that overrun internal buffers (observed at the
~32 KB threshold on Windows). Degrade gracefully with a clear
"skipping scope extraction for this file" warning instead of the
opaque "Invalid argument" surfacing through the bridge.

Verified by indexing whittlem/pycryptobot (which has 7 empty
__init__.py and 11 Python files between 34 KB and 158 KB):
2,367 nodes / 4,973 edges, no segfault, queries resolve symbols
inside the 158 KB controllers/PyCryptoBot.py.

* fix(ingestion): harden Python scope extraction fallbacks

Keep failed Python scope extraction on the bridge skip path and build synthetic module scopes before extractor indexes are derived.

Subject: [PATCH 17/40] test(ci): isolate native LadybugDB and CLI e2e flakes

createFTSIndex now short-circuits on the in-process cache before issuing
the native CALL CREATE_FTS_INDEX, so a prior writable session cannot
trigger the macOS WAL/checkpoint duplicate-create path observed on main.
The cache is also primed on the "already exists" recovery and cleared on
re-init/close/drop, keeping ensureFTSIndex semantics identical for
read-only fallbacks.

The lbug-core-adapter close+reopen test moves to the end of the suite so
its native handle churn cannot corrupt later assertions in the same
fixture.

skills-e2e moves into its own sequential vitest project so the heavy
spawnSync-driven CLI fixtures stop competing with the parallel default
project on Windows runners, fixing the C-fixture beforeAll timeout.

Subject: [PATCH 18/40] fix(cli): surface silent finalize-skips so analyze
 cannot exit 0 without persisting (#1169) (#1237)

* fix(cli): surface silent finalize-skips so analyze cannot exit 0 without persisting (#1169)

Closes #1169.

On Windows, `gitnexus analyze .` was observed to exit with code 0 after
printing only the "GitNexus Analyzer" banner. `.gitnexus/lbug.wal` was
written but `meta.json` was never persisted and the repo was not added
to `~/.gitnexus/registry.json`, so `gitnexus list` / `status` reported
no indexed repository. The reporter confirmed the same shape on both
LadybugDB (1.6.x) and the pre-LadybugDB KuzuDB build (1.4.1), so the
silent finalize-skip is upstream of the DB engine and indistinguishable
from a healthy index from the user's perspective.

This change makes that state a hard, actionable failure regardless of
the upstream root cause.

Behaviour change

- New `assertAnalysisFinalized()` invariant in `repo-manager.ts` checks
  that meta.json exists at `<repo>/.gitnexus/meta.json` AND that the
  global registry has a canonical-path-matching entry. Throws
  `AnalysisNotFinalizedError` (kind: "AnalysisNotFinalizedError") with a
  diagnostic that names the missing artifact and the storage path the
  user should inspect.
- `analyzeCommand` invokes the invariant on the rebuild path (skipped
  on `alreadyUpToDate`), so a future silent finalize-skip surfaces with
  exit code 1 and a recoverable error instead of a silent exit 0.
- `analyzeCommand` installs idempotent `unhandledRejection` and
  `uncaughtException` handlers that bypass the progress bar's console
  redirection by writing to a stderr handle captured at module load.
  This addresses the secondary symptom where the `barLog` redirection
  visually erased stack traces with `\x1b[2K\r` and stripped them via
  `String(err)`.
- The catch block also writes the failing error's full stack via the
  captured stderr, so failure diagnostics survive any downstream
  monkey-patching of `process.stdout`/`stderr`.

Tests

- `test/unit/repo-manager-finalize-invariant.test.ts` (4 tests): cover
  both `missing="meta"` and `missing="registry-entry"`, the happy path,
  and Windows case-insensitive registry path matching.
- `test/integration/cli-e2e.test.ts` adds a regression test that runs
  the real CLI on a fresh repo copy, asserts exit 0, AND verifies
  `meta.json` plus the matching registry entry are both written —
  catches any future regression of the wiring.

Validation

- `npx tsc --noEmit` passes.
- `npx vitest run --project default` passes for all my touched files
  (89 tests across 4 files). The full default suite reports 7188 pass
  with the known native LadybugDB Windows-worker flake unrelated to
  this change.
- `npx prettier --check` clean on the diff.
- `npx eslint` reports only pre-existing `any` warnings on the file;
  no new warnings introduced.
- Live repro on the issue's two-file Python fixture reproduces a
  successful index after the change: meta.json present (742 B), exit 0,
  `gitnexus list` shows the repo.

Rollback

Strictly additive — the success path is unchanged when `meta.json` is
written and the registry is updated. Reverting the four-file diff is
safe; the previous silent-finalize behaviour returns. No persisted
schema or registry shape changes.

DoD

- [x] Runtime wiring is complete on the affected CLI path.
- [x] Requested behavior is correct and existing contracts are preserved.
- [x] Smallest correct solution — one invariant, one helper, two
      handlers; no speculative abstraction.
- [x] Tests prove the changed behavior at unit AND integration level.
- [x] Required validation for `gitnexus/` was run.
- [x] Repo boundaries respected; no language-specific code, no shared
      ingestion changes, no new injection surfaces.
- [x] Diff contains only the intended change — no unrelated churn.

Made-with: Cursor

* fix(cli): enforce analyze finalization on fast path (#1169)

Address PR review feedback by checking finalization even when analyze reports already up to date, and by making the #1169 E2E guard fail on timeout instead of passing silently.

Made-with: Cursor

* test(cli): fix #1169 regression coverage on CI

Normalize macOS temp paths in the registry assertion and update the analyze worker timeout test mock for the new finalization invariant exports.

Subject: [PATCH 22/40] fix(deps): pin tree-sitter-c/cpp to fix Windows
 segfault (#1242) (#1243)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

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

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

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

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

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

Parser loader collapsed to one declarative table:

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

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

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

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

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

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

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

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

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

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

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

Addresses review feedback on #1243.

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

Decouples log severity from throw behavior:

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

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

Made-with: Cursor

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

Addresses review feedback on #1243.

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

Fix:

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

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

+/**
+ * One row per (language, optional variant) describes how to obtain a

+ *
+ *   - `load`             — returns the grammar object (lazy, called on
+ *                          first use, then cached).
+ *   - `unavailableNote`  — actionable message surfaced *whenever* the
+ *                          grammar can't be loaded. Mandatory for every
+ *                          row so failures are never silent and never
+ *                          generic.
+ *   - `optional`         — when true, a load failure does not throw:
+ *                          we report the language as unavailable and
+ *                          let callers skip files of this language.
+ *                          When false (the default), a load failure
+ *                          re-throws the original error so the
+ *                          pipeline halts loudly.
+ *   - `severity`         — log level for failure diagnostics. Defaults
+ *                          to `error` for required grammars and `warn`
+ *                          for optional ones. Set explicitly to `error`
+ *                          on optional rows whose package is listed in
+ *                          `dependencies` (not `optionalDependencies`):
+ *                          those failures indicate a real install
+ *                          problem and should never be hidden behind
+ *                          a low-severity warning.
+ *
+ * Adding or removing a grammar is one entry in this table — there is
+ * no second list, no conditional spread, and no per-grammar branch in
+ * the resolver.

Subject: [PATCH 23/40] chore(deps)(deps): bump react and @types/react in
 /gitnexus-web (#1210)

* chore(deps)(deps): bump react and @types/react in /gitnexus-web

Bumps [react](https://github.com/facebook/react/tree/HEAD/packages/react) and [@types/react](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/HEAD/types/react). These dependencies needed to be updated together.

Updates `react` from 18.3.1 to 19.2.5
- [Release notes](https://github.com/facebook/react/releases)
- [Changelog](https://github.com/facebook/react/blob/main/CHANGELOG.md)
- [Commits](https://github.com/facebook/react/commits/v19.2.5/packages/react)

Updates `@types/react` from 18.3.27 to 19.2.14
- [Release notes](https://github.com/DefinitelyTyped/DefinitelyTyped/releases)
- [Commits](https://github.com/DefinitelyTyped/DefinitelyTyped/commits/HEAD/types/react)

* fix(web): complete React 19 upgrade

Align react-dom and @types/react-dom with React 19 so npm can resolve the web dependency graph without peer conflicts. React 19 types now correctly model refs initialized with null, so widen the affected hook return contracts instead of asserting non-null DOM nodes before mount.

Validation: cd gitnexus-web && npm ci; npx tsc -b --noEmit; npm test; npm run build; npx prettier --check package.json package-lock.json src/hooks/useAutoScroll.ts src/hooks/useSigma.ts; npx eslint . (warnings only, existing baseline); npm run test:e2e (11 passed, 17 skipped).
Made-with: Cursor

Subject: [PATCH 29/40] fix(python): walk ancestors for multi-segment dotted
 imports (#1241)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(python): walk ancestors for multi-segment dotted imports (#1240)

Single-segment Python imports (`from middleware import X`) already get an
ancestor-directory walk in `resolvePythonImportInternal`, so they resolve
correctly when the importer and the imported module share a parent
directory (e.g. both under `backend/`).

Multi-segment dotted imports (`from services.sync import X`) were only
resolved against the workspace root. In a `backend/`-prefixed repo,
`from services.sync import X` from `backend/routers/cron.py` would not
resolve because `services/sync.py` does not exist at the workspace root —
only `backend/services/sync.py` does. The IMPORTS edge was dropped, the
imported names were never bound, and downstream CALLS edges to those
names were silently lost.

The fix mirrors the single-segment ancestor walk for multi-segment paths
in `resolveAbsoluteFromFiles`, and widens `hasRepoCandidate` to accept
nested `/segment/` matches so it does not bail before the walk runs.

Includes a new fixture and 5 integration tests covering:
- IMPORTS resolution for `from services.sync`, `from services.alerts`,
  `from routers.alerts` from `backend/routers/cron.py`.
- CALLS edge counts for every multi-segment-imported callee.
- Regression check: single-segment ancestor walk
  (`from auth_utils import …`) still resolves correctly.

The django-app-imports regression suite (which prevents `accounts.apps`
from spuriously matching a local `apps.py`) continues to pass — the new
nested-namespace check in `hasRepoCandidate` is bounded by an explicit
`/segment/` substring, and the workspace-root candidate check still
runs first.

* fix(python): scope hasRepoCandidate widening to importer ancestors + tighten ancestor-walk loop

Address review findings from PR #1241:

1. hasRepoCandidate's nested check now requires the matching directory to
   sit on an ancestor of the importer. Previously any nested /SEGMENT/
   path satisfied the gate, which would let a vendored copy of an
   external package (e.g. vendor/django/urls.py) gate-pass an external
   import like 'from django.urls import path' issued from app/main.py.

2. Loop bound in resolveAbsoluteFromFiles tightened from 'i >= 0' to
   'i > 0' to skip a redundant root-candidate recheck (the workspace-root
   direct check above already covers that case).

3. Doc-comment in resolveAbsoluteFromFiles now states the precedence
   order explicitly: workspace root > closest ancestor > suffix fallback.

Tests added:
- Vendored-external false-positive guard (vendor/django/urls.py must not
  resolve from app/main.py).
- Workspace-root vs ancestor precedence (root services/sync.py wins over
  backend/services/sync.py for a backend/routers/cron.py importer).

215/215 python integration tests pass (+4 from this change). tsc --noEmit
green.

Subject: [PATCH 30/40] fix(group): contract extractors honour .gitnexusignore
 via shared IgnoreService (#1185) (#1247)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(group): contract extractors honour .gitnexusignore via shared IgnoreService (#1185)

The HTTP, gRPC, and topic contract extractors each globbed the repo
with a hardcoded `ignore: ['**/node_modules/**', '**/.git/**',
'**/dist/**', '**/build/**', '**/vendor/**']` array, bypassing the
shared `IgnoreService` that the rest of the ingestion pipeline uses
for `.gitnexusignore` and `.gitignore` parsing. Result: a vendored
Python venv (`mentor_env/`), generated stubs, or any user-defined
exclusion silently produced false-positive contracts.

Replace each hardcoded array with `createIgnoreFilter(repoPath)`,
mirroring the canonical pattern in `filesystem-walker.ts`. The 5
hardcoded names are all in `DEFAULT_IGNORE_LIST`, so default
behaviour is preserved; users now also get `.gitnexusignore`
patterns, the rest of the hardcoded list (e.g. `__pycache__`,
`.pytest_cache`), and the `.gitnexusignore` negation semantics
introduced in #771.

The topic extractor additionally filters Go `*_test.go` at the glob
level. That filter is preserved via a small wrapper around
`createIgnoreFilter` that short-circuits before delegating, so
glob-level pruning still applies and the existing `_test.go` skip
test (with new content asserting the pruning is real) still passes.

Tests added to all three `*-extractor.test.ts` files exercising
`.gitnexusignore` honouring end-to-end via real temp directories.

* test(group): exercise gRPC source-scan ignore + add .gitignore-only coverage (#1185)

Addresses two findings from the @claude review on PR #1247:

[medium] The gRPC ignore test claimed to cover both proto-context and
source-scan paths but only wrote a .proto file under mentor_env/.
Added a Python `_pb2_grpc.<Name>Stub(channel)` consumer file under the
same ignored dir (mirroring the canonical pattern from
`test_extract_python_stub_returns_consumer`); without the
`.gitnexusignore` filter that file would emit a consumer contract.
The test now exercises both `createIgnoreFilter` calls inside the gRPC
extractor (`buildProtoContext` + `extract`) in a single run, with both
defence-in-depth path-prefix assertions and a specific
`role: consumer` LeakedService assertion.

[low] Added one shared .gitignore-only test on the HTTP extractor.
`createIgnoreFilter` reads both `.gitignore` and `.gitnexusignore` via
`loadIgnoreRules`, but no extractor-level test exercised the
`.gitignore` path. One shared test is sufficient because all three
extractors consume the same filter object — verified at
`IgnoreService` level already.

The remaining [low] finding — "negation semantics (!pattern) not
tested at extractor level" — is deferred deliberately, not skipped.
Three reasons:

  1. The negation logic (introduced in #771) lives entirely inside
     `createIgnoreFilter`'s `hasExplicitUnignore` ancestor-walk in
     `ignore-service.ts`. The extractors only consume the returned
     filter object — they never inspect patterns, never call
     `hasExplicitUnignore` directly, and have no code path that could
     diverge from the IgnoreService's negation behaviour.

  2. Negation is already locked in by 8 dedicated unit tests in
     `test/unit/ignore-service.test.ts` (the #771 suite), plus the
     `!parent/` + `parent/child/` last-match-wins regression test
     added in PR #1046. An extractor-level negation test would
     re-prove the same code path and would not catch any failure mode
     the existing tests don't already catch.

  3. The bot itself flagged the gap as "Acceptable to leave as
     follow-up referencing existing IgnoreService negation tests" —
     the deferral matches its own recommendation.

If a future change inserts an extractor-side wrapper around the filter
(as topic-extractor.ts already does for `*_test.go`) that could
plausibly affect negation, an extractor-level negation test should be
added at that point — not pre-emptively here.

Subject: [PATCH 31/40] fix(cli): keep GitNexus ignores inside .gitnexus
 (#1248)

* fix(cli): keep GitNexus ignores inside .gitnexus

Avoid mutating analyzed repositories' root .gitignore while keeping generated GitNexus state untracked via .gitnexus/.gitignore.

Made-with: Cursor

* fix(cli): also use git info exclude for GitNexus storage

When an analyzed repo has a real .git directory, add .gitnexus/ to .git/info/exclude so local Git metadata ignores generated storage without touching root .gitignore.

Made-with: Cursor

* fix(cli): keep skip-git subdir indexes ignored

Ensure full analyze always writes the internal GitNexus ignore file so parent Git repositories stay clean for --skip-git subdirectory indexes.

Made-with: Cursor

Subject: [PATCH 37/40] feat(mcp): add tool safety annotations (#1127)

* feat(mcp): add tool safety annotations

* test(mcp): address PR #1127 review follow-ups

- Replace private `_requestHandlers` SDK access in server.test.ts with
  `Client` + `InMemoryTransport.createLinkedPair()` for the tools/list
  annotation propagation test. The new path uses supported public APIs
  and surfaces SDK changes loudly instead of silently degrading.
- Extract `OPEN_WORLD_READ_ONLY_TOOLS` set in tools.test.ts so future
  read-only open-world tools can be added without rewriting the
  invariant; preserves the current "only `query` is open-world" guard.
- Add inline rationale on `group_sync` annotations explaining the
  conservative `idempotentHint: false` (writes contracts.json on every
  call even when output is deterministic).

No runtime behavior change. Annotations themselves and tools/list shape
are unchanged.

Subject: [PATCH 38/40] fix(mcp): avoid git from non-repo cwd in sibling cwd
 match (#1138) (#1293)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(mcp): avoid git shellout from non-repo cwd for sibling match

checkCwdMatch used getGitRoot(cwd), which runs git rev-parse from the
launch cwd (often \C:\Users\gergo in MCP stdio). Resolve the cwd git root via
ancestor .git checks first, then keep existing remote-based sibling
logic.

Fixes #1138

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

* test(mcp): address PR #1293 review follow-ups

Three test gaps flagged by review on the #1138 fix:

- sibling-clone-drift.test.ts: the existing "non-git cwd" test only
  asserted match=none, which the pre-fix code also returned (by
  silently failing the spawn). Wrap child_process / node:child_process
  with passthrough vi.fn() spies and assert no execSync/execFileSync
  call is recorded when checkCwdMatch runs against a non-git cwd, so a
  regression that re-introduces the spawn fails loudly.
- git.test.ts: add coverage for findGitRootByDotGit's three untested
  inputs — a `.git` FILE (linked worktree / submodule), a path that
  does not exist, and a file path inside a repo (must walk from the
  parent dir). Each asserts no subprocess was spawned.

No production code changes. Test additions only.

Subject: [PATCH 39/40] refactor(ingestion): consolidate per-language patterns
 into LanguageProvider (#1279)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor(ingestion): consolidate per-language patterns into LanguageProvider

Move entry-point name patterns and AST framework detection patterns from
shared maps in entry-point-scoring.ts and framework-detection.ts into each
LanguageProvider. The shared files now build their lookup tables dynamically
from the provider registry at module load.

This aligns with the architecture principle that shared pipeline code must
not name languages. Adding a new language no longer requires modifying
entry-point-scoring.ts or framework-detection.ts — the provider file is
the single source of truth for all language-specific data.

New LanguageProvider fields:
  - entryPointPatterns: RegExp[] (default: [])
  - astFrameworkPatterns: AstFrameworkPatternConfig[] (default: [])

* test(ingestion): add provider-registry, multiplier/reason, and Kotlin/Dart/Ruby entry-point coverage

Addresses review feedback on the per-language pattern consolidation:

- Runtime guard that providers map covers every SupportedLanguages member,
  catching enum/registry drift that the compile-time `satisfies` cannot.
- Multiplier/reason parity assertions for nestjs (3.2/nestjs-decorator),
  spring (3.2/spring-annotation), and fastapi (3.0/fastapi-decorator) so a
  silent value change during future relocations would fail loudly.
- Entry-point pattern coverage for Kotlin (Android lifecycle, ViewModel,
  Service), Dart (Flutter widget lifecycle), and Ruby (call/perform/execute)
  — the three providers whose patterns moved without representative tests.

* refactor(ingestion): apply satisfies AstFrameworkPatternConfig[] to remaining providers

The c-cpp, dart, php, ruby, and swift providers imported AstFrameworkPatternConfig
but never used it, which the root ESLint config flagged as a hard error in the
quality / lint CI gate.

Use the type the same way csharp/go/java/kotlin/python/rust/typescript already do —
as a satisfies assertion on the astFrameworkPatterns array. This both clears the
unused-import error and gives every provider compile-time validation of pattern
shape, narrowing the gap that the original review flagged about lost exhaustiveness
on the optional astFrameworkPatterns field.

Subject: [PATCH 40/40] fix(typescript): name HOC-wrapped const declarations
 (forwardRef / memo / useCallback / useMemo / observer) (#1261)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(typescript): name HOC-wrapped const declarations (forwardRef / memo / useCallback / useMemo / observer / debounce)

Follow-up to issue #1166 / PR #1175. After fixing HOF callbacks (Promise
fan-out, queryFn pair-arrows, multi-action Zustand stores) and JSX-as-call,
the dominant residual 0%-capture pattern in real React UI codebases was
the HOC-wrapped variable declaration:

  const Button = React.forwardRef((props, ref) => { ... })
  const Card = memo((props) => { ... })
  const handleClick = useCallback(() => { ... }, [])
  const computed = useMemo(() => { ... }, [])
  const debouncedSearch = debounce((q) => { ... }, 250)

All share the AST shape `lexical_declaration > variable_declarator >
call_expression > arguments > arrow_function`. Pre-fix, neither the
registry-primary `query.ts` nor the legacy `tree-sitter-queries.ts` had
a `@declaration.function` pattern matching this shape, and the legacy
DAG's `tsExtractFunctionName` only walked `variable_declarator` and
`pair` parents — `arguments` parents fell through with `funcName = null`.

Result: every shadcn/Radix component, every memoised React component,
and every `useCallback` / `useMemo` callback bound to a const registered
as anonymous; calls inside attributed to the file. Sourcerer-fe audit:
~296 declarations affected (~57 forwardRef + ~21 memo + ~161 useCallback
+ ~57 useMemo).

Fix:
  - 4 new tree-sitter patterns in `languages/typescript/query.ts`
    (registry-primary), anchored on the inner arrow_function /
    function_expression — same anchor discipline as the existing
    `lexical_declaration` and `pair` patterns from PR #1175.
  - 8 mirrored patterns in `tree-sitter-queries.ts` (4 in
    TYPESCRIPT_QUERIES, 4 in JAVASCRIPT_QUERIES) for the legacy DAG
    and the CI parity gate.
  - New `arguments`-parent branch in `tsExtractFunctionName` that
    walks `arguments → call_expression → variable_declarator` and
    returns the const's name. Three guards keep it strictly scoped
    to HOC-wrapped declarations; bare statement-level HOC calls fall
    through anonymous.

Tests:
  - 11 integration tests + 9 minimal TS/TSX fixtures exercising
    forwardRef / memo / useCallback / useMemo / observer / debounce,
    with positive (named-Function + correct CALLS edge), negative
    (no phantom Functions for unbound HOCs, no phantom self-loops,
    no first-sibling-wins leakage), and cross-pollination assertions.
  - 8 new unit tests in `call-attribution-issue-1166.test.ts`
    pinning the legacy-DAG path: 6 attribution tests + 2
    @definition.function capture tests.

Trade-off documented inline: chained array-method declarations
(`const x = arr.find((y) => p(y))`) match the same shape and produce
a mostly-harmless phantom `Function:x` with one outgoing edge. The
false-positive cost is negligible vs. the React UI coverage gain.

Verification: - 11/11 typescript-hoc-wrapped (registry-primary)
  - 26/26 call-attribution-issue-1166 (8 new + 18 pre-existing)
  - 266/266 across all 4 typescript resolver test files (registry)
  - 236/236 typescript.test.ts on legacy DAG (CI parity gate)
  - 1693/1693 across all non-Kotlin/Swift resolver test files
  - tsc --noEmit clean; prettier clean; eslint clean (no new warnings)

* test(typescript): pin documented HOC trade-offs and close var-form parity gap

Addresses the four findings on PR #1261 (Claude bot review for #1261).
All findings flagged missing assertion tests for behaviour already documented
in code comments — none reported a real bug. The verdict was
"production-ready with minor follow-ups"; these tests strengthen the
documentation-to-test contract.

[medium #1] Array-method false-positive
  Pin `const found = items.find((item) => predicate(item))` →
  `predicate.attributedTo === 'found'` as an accepted FP. The const is a
  value, never invoked, so no incoming CALLS edge ever points at it; the
  outgoing edge is a minor mis-attribution we accept rather than maintain
  a HOC allowlist.

[medium #2] Nested HOCs (`memo(forwardRef(...))`) — no phantom Function:Wrapped
  Two integration tests in `typescript-hoc-wrapped.test.ts`:
    1. `Wrapped` is NOT a Function node (the outer call's first arg is a
       call_expression, not an arrow — no @declaration.function pattern
       matches the outer shape).
    2. The deepest arrow's `helper()` call is NOT attributed to
       Function:Wrapped (the deepest arrow is anonymous because
       call_expression.parent is `arguments`, not `variable_declarator`),
       and no Function-sourced CALLS originate from `nested.tsx`.

[medium #3] Multi-arrow argument dedup
  Pin `const x = call(() => first(), () => second())` — both arrows share
  the same `arguments → call_expression → variable_declarator` ancestor
  chain on the legacy DAG, so both attribute to "x". Documents the
  registry-primary dedup story alongside.

[low #4] `var X = HOC(...)` parity gap
  Registry-primary `query.ts` had `(variable_declaration ...)` HOC patterns
  but legacy `tree-sitter-queries.ts` (TS + JS) did not. Closes the gap by
  mirroring two `(variable_declaration ...)` HOC patterns into both legacy
  sections so the parity gate stays tight even if a codebase mixes
  `var X = HOC(...)` with `const X = HOC(...)`.

Validation
  - Targeted: 41/41 (28 unit + 13 integration) on registry-primary.
  - Broader TS suite: 60/60 across 4 resolver test files.
  - CI parity gate (`typescript.test.ts`): 236/236 on legacy DAG and 236/236
    on registry-primary.
  - Prettier clean. ESLint clean (5 pre-existing non-null-assertion
    warnings in the test file, unrelated). tsc --noEmit clean.

+ * TypeScript: CALLS edges from inside HOC-wrapped variable declarations.
+ *
+ * Follow-up to issue #1166 / PR #1175. After fixing HOF callbacks (Promise
+ * fan-out, queryFn pair-arrows, Zustand actions) and JSX-as-call, the
+ * residual 0%-capture pattern in real React UI codebases (Sourcerer-fe
+ * audit) was the HOC-wrapped declaration:
+ *
+ *   const Button = React.forwardRef((props, ref) => { ... })
+ *   const Card = memo(({ ... }) => { ... })
+ *   const handleClick = useCallback(() => { ... }, [])
+ *   const computed = useMemo(() => { ... }, [])
+ *   const Item = observer((props) => { ... })
+ *   const debouncedSearch = debounce((query) => { ... }, 250)
+ *
+ * All share the AST shape `lexical_declaration > variable_declarator >
+ * call_expression > arguments > arrow_function`. Pre-fix, none matched
+ * any `@declaration.function` pattern (the registry-primary `query.ts`
+ * only knew about `variable_declarator > arrow_function` directly), and
+ * the legacy DAG's `tsExtractFunctionName` only walked `pair` /
+ * `variable_declarator` parents — `arguments` parents fell through with
+ * `funcName = null`.
+ *
+ * Result: every shadcn/Radix component, every memoised React component,
+ * every useCallback/useMemo hook callback registered as anonymous, and
+ * calls inside their bodies attributed to the file. Sourcerer-fe alone
+ * had ~296 such declarations affected (57 forwardRef + 21 memo + 161
+ * useCallback + 57 useMemo).
+ *
+ * Fix:
+ *   - 4 new tree-sitter patterns in `typescript/query.ts` (registry).
+ *   - 4 mirrored patterns in `tree-sitter-queries.ts` (legacy).
+ *   - `tsExtractFunctionName` extended with a third branch that walks
+ *     `arguments → call_expression → variable_declarator`.
+ *
+ * Each test fixture below isolates one wrapper shape with the call
+ * target defined in `helpers.ts` (cross-file resolution).
