The stale-index hint must prefer a PATH-installed `gitnexus` over `npx gitnexus`
(which crashes npm 11's arborist, #1939). #1945 already does this via
`formatAnalyzeCommand`, but its `resolveOnPath` shelled out to `where`/`which` —
which fails outright when the probe binary is itself unreachable (a sanitized
hook PATH without System32 / `/usr/bin`), exactly the Windows case #1938 reports.
Replace the subprocess (and a hand-rolled fallback) with a single spawn-free
PATH scan — issue #1938's preferred "Option A". One code path, identical on every
OS:
- no dependency on `where`/`which` being reachable;
- no shell-spawn surface (CVE-2024-27980) and no spawn timeout to tune;
- Windows matches PATHEXT extensions only (mirrors `where`/cmd.exe), so neither a
`.ps1`-only shim nor a bare extensionless file is a false positive;
- `preferExecExt` keeps the `.cmd`/`.bat`/`.exe` wrapper preference.
`resolveOnPath` is now pure (platform/env injectable) and exported; `pickPathMatch`
and the interim `scanPathForCommand` are removed. Version detection still spawns
`npm`/`pnpm --version` (unavoidable) and is unchanged.
Tests: drive `resolveOnPath` directly across POSIX/Windows cases (PATHEXT, `.ps1`,
extensionless, preferExecExt, X_OK) + a cross-platform `formatAnalyzeCommand`
end-to-end case, plus the existing hook e2e auto-detection tests and new
`pathWithoutGitNexus`/`envWithPath`/`createGitNexusPathEntry` helpers. Both
`resolve-analyze-cmd.cjs` copies kept byte-identical.
Validated: tsc clean, prettier clean, eslint 0 errors, 312 targeted tests pass
(unit + hook e2e + the resolver's other consumers).

* test(ingestion): failing target tests + graph-integrity helper for scoped-declaration nodes (U1, #1975)
Adds findDanglingEdges() and pipeline-level tests asserting that Ruby
namespaced class/module declarations materialize a Class/Trait node with
a resolving HAS_METHOD edge. Red by design on the pre-fix base (5 failing)
— the fix lands in U2 (shared core) + U3 (Ruby enablement).

* fix(ingestion): materialize graph nodes for Ruby namespaced class/module declarations (U2/U3, #1975)
Widen the Ruby legacy structure query so `class Foo::Bar` / `module Baz::Qux`
(name field is a scope_resolution node) match @definition.class/.module as
separate top-level patterns. The node is keyed by its full scoped name, which
matches the HAS_METHOD owner id that findEnclosingClassInfo derives from the
same name field — so the previously-dangling ownership edges now resolve, and
distinct namespaces (Foo::Bar vs Baz::Bar) stay distinct nodes (no collision).
No change to findEnclosingClassInfo (zero call-resolution blast radius) and no
scope-extractor/golden/bench impact — the fix is purely the legacy structure
query gate. Finalizes the U1 target assertions to the qualified-name identity.
Validated: 134/134 Ruby resolver tests pass on BOTH legs; tsc --noEmit clean;
dangling HAS_METHOD edges on the ruby-namespaced fixture drop from 3 to 0.

* fix(ingestion): resolve C++ out-of-line nested definition method ownership (U4, #1975)
For an out-of-line `struct Outer::Inner { ... }`, the container name is a
qualified_identifier, so findEnclosingClassInfo derived the owner id from the
full `Outer::Inner` text — but the type is keyed by its in-class declaration
(the nested `Inner` node), leaving the method's HAS_METHOD edge dangling.
Reduce a qualified_identifier container name to its tail segment for the owner
id/name, matching how inline nested definitions are already keyed. Node-type
scoped, so Ruby's scope_resolution names stay full (distinct-by-namespace) and
no language is named in shared code. Only out-of-line-def methods (already
dangling) change behavior — zero impact on bare classes or call resolution.
Validated: C++ 268/268 default leg, 205+63-skip legacy leg, no regression;
2 new target tests pass both legs; Ruby namespaced tests still pass; tsc clean;
scope-capture bench rebaselined (cpp +cpp-out-of-line-class fixture) — --check
PASS (13 langs). Dangling HAS_METHOD on the new fixture: 1 -> 0.

* fix(ingestion): resolve Rust scoped impl-target method ownership (U5, #1975)
`impl path::Type` and `impl Trait for path::Type` name the target with a
scoped_type_identifier. Two coordinated fixes:
- findEnclosingClassInfo: reduce a scoped_type_identifier impl target to its
trailing type name (both the trait-impl `for` branch and the inherent
branch), matching the type's own tail-keyed declaration.
- tree-sitter-queries: add a @definition.impl arm for scoped inherent impls so
the Impl node is materialized (keyed by the same tail) instead of missing.
Together the trait-impl method owns through the real Struct node and the
inherent-impl method owns through a real Impl node — no dangling edges. Rust's
scoped_type_identifier has a name: field, so the tail extraction is exact.
Validated: Rust 163/163 on BOTH legs, no regression; new target test passes;
C++/Ruby suites unaffected; tsc clean; scope-capture bench rebaselined
(rust +rust-scoped-impl fixture) — --check PASS (13 langs). Dangling 1 -> 0.

* test(ingestion): cross-namespace collision test + regenerate ruby/rust captures goldens (U6, #1975)
- Add ruby-tail-collision fixture + test: Foo::Bar and Baz::Bar share the tail
'Bar' but must stay two distinct Class nodes (locks the KTD-2 anti-collision
guarantee from full-scoped-name keying). No dangling, no cross-wiring.
- Regenerate the ruby + rust captures goldens for the fixtures added in U3-U6
(ruby-tail-collision, rust-scoped-impl). Both diffs are additive-only — a
single new entry each, existing entries byte-identical (no capture-logic
drift; the fixes are in the legacy structure query + findEnclosingClassInfo,
not the scope-extractor).
- Re-baseline the ruby scope-capture fingerprint (81->82 fixtures).
N/A-language verification: C#/Java/PHP have no class-declaration scoped-name
gap and show no regression (606 passed; the 2 C# worker-pool failures are the
known worktree 'parse-worker.js not built' limitation, unrelated to this change).

* revert(ingestion): drop C++/Rust scoped-owner reduction; ship Ruby-only (#1975)
The self-tri-review of PR #1977 (review 4411683756) found — and reproduced —
that the C++/Rust tail-reduction in findEnclosingClassInfo collides same-tail
types declared in the same file (struct Outer::Inner + struct Other::Inner ->
one Struct:Inner node, methods silently mis-attributed; same-named members
merge). Root cause is pre-existing: GitNexus keys nested-type nodes by their
tail name within a file, so even plain inline same-tail nested types already
merge. A correct fix needs fully-qualified nested-type node identity — a broad
change deferred to #1978.
This reverts the C++ (qualified_identifier) and Rust (scoped_type_identifier
impl) owner reductions in ast-helpers.ts, the Rust @definition.impl scoped arm,
and the cpp/rust fixtures+tests+golden+bench entries. The Ruby fix is unaffected
(it keys the node by the full scoped text — no collision) and stays:
namespaced class/module node materialization + the cross-namespace collision test.
Validated Ruby-only: 136/136 both legs; ruby+rust captures goldens 19/19;
bench --check PASS (14 langs); tsc clean.

* fix(ingestion): collision-safe C++/Rust scoped-declaration node ownership (#1975)
Re-introduces the C++/Rust fix the tri-review reverted, using a collision-safe
approach instead of owner tail-reduction (which merged same-tail types in one
file). Key the scoped DECLARATION's node by its full qualified text so it
matches the owner id and stays distinct from a same-tail type elsewhere:
- C++: widen the legacy structure query to materialize a node for out-of-line
defs (class/struct Outer::Inner — name is qualified_identifier), keyed by the
full text. No findEnclosingClassInfo change needed — BASE already derives the
full-text owner, which now matches. Outer::Inner and Other::Inner stay
distinct; 3-level A::B::C resolves. (A redundant forward-decl node remains.)
- Rust: @definition.impl arm for scoped inherent impls (keyed full) +
findEnclosingClassInfo inherent-impl branch accepts scoped_type_identifier
with full text. impl a::Inner and impl b::Inner stay distinct.
Collision-aware fixtures + positive owner-identity assertions (per the
tri-review) replace the single-type fixtures. Deferred to #1978: Rust trait
impls on a scoped struct path (impl T for a::Inner) and the pre-existing inline
same-tail node collision — both need qualified struct-node identity.
Validated: Ruby 136/136, C++/Rust 434/434 both legs (371+63-skip legacy);
ruby+rust captures goldens 19/19 (additive); bench --check PASS (14 langs);

* feat(scope-resolution): migrate Dart to registry-primary call resolution (#939)
Add a Dart scope-resolution module (languages/dart/) mirroring the Swift
template and flip Dart to registry-primary. Resolution edges
(CALLS/IMPORTS/ACCESSES/EXTENDS/IMPLEMENTS/METHOD_IMPLEMENTS) now route
through the shared registry pipeline with byte-for-byte parity against the
legacy DAG: test/integration/resolvers/dart.test.ts passes 53/53 under both
REGISTRY_PRIMARY_DART=0 and =1 (scripts/run-parity.ts --language dart: 2/2).
Dart-specific handling:
- Function scopes are synthesized to span signature..body (tree-sitter
function_signature/function_body are siblings, not parent/child).
- extends rides @reference.inherits (EXTENDS via the generic pre-pass);
implements/with are carried as __heritage__ side-effect imports and
emitted as IMPLEMENTS, since Dart `implements <class>` must be IMPLEMENTS
regardless of the target's symbol kind.
- imports are wildcard (whole-library) with expandsWildcardTo so imported
return types propagate cross-file (var u = getUser(); u.save()).
- getInnerSignature now self-returns a bare signature node so top-level
function params/return/name extract (legacy-safe: legacy only ever passes
method_signature/declaration wrappers).
Also: add Dart scope-capture bench coverage (linear ~0.99 scaling); update
two tests that used Dart as a non-migrated control (Vue / forced legacy).

* fix(scope-resolution): close Dart registry-primary parity gaps from review
Adversarial review of #1970 surfaced real divergences from the legacy DAG on
constructs the 10 fixtures don't exercise. All fixed; parity gate still 2/2
(now 55/55 each mode):
- Implicit-constructor construction (`Foo()` with no explicit ctor): the
legacy DAG emits `caller -> Foo` (Class) but registry emitted nothing
(callee tagged @reference.call.free never reaches constructorCallTargetsClass).
Re-tag UpperCamelCase free-callees to @reference.call.constructor (Dart types
are UpperCamelCase) so they link to the Class. Locked in with a regression
fixture + test that passes in BOTH modes.
- Cascade calls (`list..add(1)..sort()`) were dropped — cascade_section has no
`selector` wrapper, so the reference walk never saw them while legacy emitted
them as free calls. Add a cascade_section handler.
- BUILT_INS (setState/then/push/pop/listen/...) were not suppressed on the
registry path, so a user symbol shadowing one produced a spurious CALLS edge
the legacy DAG suppresses. Skip built-in-named call refs at capture time
(extract the set to a leaf module shared with the provider).
- Enhanced-enum methods mis-parented to Module (no enum scope). Add
`(enum_declaration) @scope.class` so enum members are owned by the enum.
Re-baseline the Dart scope-capture fingerprint (linear ~0.95).

* feat(scope-resolution): apply issue #1926 F24/F25 findings to the Dart scope path
Issue #1926 catalogs Dart parsing-layer coverage gaps. Apply the two that the
registry-primary scope-resolution path owns (call edges + call attribution),
registered as legacy-expected-failures since they are scope-resolver-only wins.
- F24: the scope path's unified tree-walk already captures member calls
(obj.method()) in return / list-literal / named-argument / arrow-body
contexts — the legacy DAG only captures them under expression_statement /
initialized_variable_definition. Lock it with the dart-member-call-contexts
fixture + tests.
- F25 (constructor portion): a constructor's body is a sibling of the WRAPPING
method_signature (class_body > method_signature > constructor_signature, then
function_body), so findFunctionBody now walks up to the method_signature
wrapper. Constructor bodies get a Function scope and their body-calls
attribute to the Constructor (a valid caller anchor) instead of the class.
Add the dart-constructor-body fixture + test.
Switch dart.test.ts to createResolverParityIt('dart') and add the dart entry to
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES (5 wins). Both modes pass:
run-parity --language dart → 2/2 (registry 60/60; legacy 55 pass + 5 skipped).
Not applicable to the scope path (structure-phase / shared-pipeline, tracked by
#1926's legacy fix): F25 getter/setter (Property is not a caller anchor) and
operator (no Method node emitted by the structure phase) bodies; F26 (static
field Property nodes); F27 (no generic_type reference in the scope module);
F28/F29 (typedef/variable node extraction). Re-baseline the Dart scope-capture
fingerprint (linear ~1.0).

* fix(scope-resolution): fix Dart named-constructor file-drop + container-name mis-binding (tri-review)
Multi-engine tri-review (GitNexus + CE personas + Codex gpt-5.5) of #1970
found a P0 the parity gate missed plus a P2 wrong-edge:
- P0 (file drop): a named constructor with a body (`class A { A.named() {…} }`,
idiomatic Dart) parses as ONE constructor_signature carrying multiple `name:`
fields, so the scope query matched it more than once and synthesized two
identical-range @scope.function captures → ScopeTreeInvariantError(duplicate-
scope-id) → extractParsedFile swallowed it → the WHOLE file was dropped from
registry-primary resolution (CALLS=0 vs legacy CALLS=2). Introduced by the
#1926 F25 findFunctionBody change that started giving constructors body
scopes. Fix: dedup function-like declarations by their statement node so each
is emitted once. Add dart-named-constructor-body fixture + a parity guard test
(both modes) that fails if the file is dropped, plus the named-ctor F25
attribution win (registry-only).
- P2 (wrong edge): normalizeDartType's Future<X>/List<X> unwrap is unreachable
(generic args are stripped upstream to a bare `Future`/`List`), so a return/
field type binding to the bare container name let a same-named user class
(`class Stream {…}`) capture the receiver — a wrong CALLS edge legacy didn't
emit. Suppress type bindings that normalize to a bare container name (leaving
the call unresolved, matching legacy) instead of binding to the container.
Both modes still pass: run-parity --language dart → 2/2 (registry 62/62; legacy
56 + 6 skipped). Re-baseline the Dart scope-capture fingerprint. Also: refresh
the captures.ts module doc (constructors get scopes; cascade calls).

* fix(scope-resolution): address Dart tri-review follow-ups (heritage collision + polish)
- P2 heritage cross-file name collision: emitDartHeritageEdges resolved both
child and base by a global last-write-wins simple-name map, so two files each
declaring `class Logger` (one `implements Logger`) produced a wrong-file
IMPLEMENTS edge. Resolve with same-file affinity (prefer a same-file class,
then a workspace-unique match, else refuse to guess) — the #1951 file-affinity
pattern. Add dart-heritage-name-collision fixture + a parity test (both modes
resolve same-file). Also reason-qualify the dedup key so `implements X` + `with X`
keep distinct edges.
- Polish: buildDartMro uses Sets instead of Array.includes-in-loop; merge-bindings
uses named tier constants matching swift; drop the dead no-op stripQuotes in
import-target (targetRaw already arrives quote-stripped).
Both modes pass: run-parity --language dart → 2/2 (registry 63/63; legacy 57 + 6
skipped). Re-baseline the Dart scope-capture fingerprint.

* test(hooks): stage resolve-analyze-cmd.cjs for antigravity adapter; harden load checks
The antigravity adapter gained a top-level require('./resolve-analyze-cmd.cjs')
but stageAdapter() did not copy it, so the spawned adapter crashed with
MODULE_NOT_FOUND. Three load-sensitive tests failed; four silent-path tests
false-passed on empty stdout.
Stage the helper alongside the other sibling helpers, and assert status===0 and
no MODULE_NOT_FOUND on the four silent-path tests so a non-loading hook can never
pass green again. Force a deterministic invocation mode in the stale-index test
so the emitted analyze command no longer varies by CI-runner PATH.

* fix(cli): standardize invocation hints on gitnexus@latest; single-source CJS helper
NPX_REF becomes a literal `gitnexus@latest` in resolve-invocation.ts, dropping
the package.json require and the module-load throw (a malformed/absent version
can no longer crash any CLI command at import). The safety this PR delivers is
the install method steered to (global / pnpm dlx), not a pinned gitnexus
version, and the in-repo CJS mirror already degraded to `latest` once copied
outside the package.
Make the two resolve-analyze-cmd.cjs copies byte-identical and add a parity
test that fails on drift. The separate, version-pinned NPX_REF that setup.ts
writes into the MCP server registration is intentional and left unchanged.

* perf(cli): move npm-11 npx warning off module load; memoize invocation mode
warnIfNpm11NpxRisk() ran at index.ts module load, so every CLI invocation
(including the `gitnexus mcp` stdio hot path) paid which/where + npm --version
spawns — against the lazy-startup/MCP-stdout discipline (#207, #1383). Move the
call into analyzeCommand, after the ensureHeap() re-exec guard, so it fires once
in the working process and only for `analyze`.
Memoize the PATH-probe-derived invocation mode (the GITNEXUS_INVOCATION override
stays uncached) so repeated callers don't re-probe, and add a test-only reset so
the cache + once-only warning flag don't leak across the unit suite. Covers the
mode!=='npx', npm<11, and npm-absent suppression branches.

* fix(cli): detect .exe/extensionless global gitnexus shims on Windows
The winGitnexusWrapper branch only matched .cmd/.bat, so a global gitnexus
installed by Volta or scoop (a .exe or an extensionless shim) was missed and the
hint fell back to pnpm/npx. Accept .exe and treat any non-empty `where` hit as
on-PATH (the emitted hint is `gitnexus analyze` regardless of which shim
resolves it). Mirror the change into both resolve-analyze-cmd.cjs copies so the
TS source and the byte-identical hook mirrors stay in sync.
Add Windows-mocked test cases (.exe-only, extensionless, .cmd preference, CRLF
stripping) and register resolve-invocation.test.ts in cross-platform-tests.ts so
the windows-latest runner exercises the branch.

* fix(cli): emit fixed pnpm dlx analyze command in generated AGENTS.md/CLAUDE.md
ai-context baked a machine-resolved command (formatAnalyzeCommand) into
git-tracked AGENTS.md/CLAUDE.md, so the stale-index hint varied per machine and
churned across branches (the #1706 class). Emit the fixed string
`pnpm dlx gitnexus@latest analyze` instead: committed AI-context is the most
authoritative instruction an agent reads, so it must name an install-free,
crash-free method — never `npx`, the npm-11 path #1939 steers away from.
formatAnalyzeCommand stays exported and unit-tested in resolve-invocation.ts
(it still mirrors the two .cjs hook copies); ai-context just no longer calls it.

* refactor(cli): unify hook-helper copy into one non-silent routine
installClaudeCodeHooks copied its four hook helpers in separate try/catch blocks

result) with a single canonical helper list (including resolve-analyze-cmd.cjs)
and the antigravity loop's error-reporting policy, and use it from both paths so
a missing helper surfaces as a setup error instead of a silent runtime crash.
Assert both the Claude and Antigravity install paths co-locate
resolve-analyze-cmd.cjs next to the adapter, and that a failed copy records an
error rather than passing silently.

* test(cli): enforce TS<->CJS invocation parity and guard CLI startup posture
Tier-2 review found two in-scope gaps in the #1945 follow-up:
- The "mirrors resolve-invocation.ts / test enforces parity" comments overclaimed:
the parity test only compared the two .cjs copies to each other, so the TS
source and the CJS hook copies could silently drift (NPX_REF, the per-mode
command, and the Windows shim regex were hand-edited in all three this PR).
Add TS<->CJS value parity (NPX_REF + formatAnalyzeCommand for every forced
mode) and a source-level shim-regex parity check, and make the mirror comments
accurately describe what is enforced.
- No test locked the R3/R4 startup posture, so re-adding warnIfNpm11NpxRisk()
(or any resolve-invocation import) at index.ts module scope -- the #207/#1383
lazy-startup regression -- would pass CI. Add a guard asserting index.ts has
no module-load invocation probe and the warning is wired into analyzeCommand.

* refactor(cli): collapse npx-invocation resolver to one source of truth
PR #1945 carried the gitnexus/pnpm/npx selection in three hand-synced
places — the canonical hook helper, its byte-identical plugin copy, and a
full TypeScript re-implementation in resolve-invocation.ts — kept in lockstep
by per-mode-command and regex-extracted-by-regex parity tests. The TS
formatAnalyzeCommand had no production caller (ai-context emits a fixed
string), and the module memoized + exposed a test-only reset for a "repeated
callers" case that has exactly one caller.
Make hooks/claude/resolve-analyze-cmd.cjs the single source: extract the
Windows-shim line-picking into a pure, exported pickPathMatch() and add an
injectable probe to resolveInvocationMode() so the shipped logic is testable
without spawning or global mocks. resolve-invocation.ts (118 -> 59 lines) now
consumes that cjs via createRequire for resolveInvocationMode/NPX_REF and adds
only the CLI-only npm-version probe and warning; the relative path resolves
identically from src/cli/ (tsx, vitest) and dist/cli/ (shipped, hooks/ is a
published sibling of dist/). Tests exercise the real shipped artifact, the
NPX_REF/mode-command parity scaffolding is dropped (one implementation can't
drift), and parity narrows to the two cjs copies staying byte-identical.
No behavior change: hook stale-index hints and the analyze warning are
byte-identical; the pre-existing setup.ts resolveGitnexusBin is untouched.

Add a load-time guard on the createRequire(resolve-analyze-cmd.cjs) cast so a drifted/renamed cjs export fails loudly at module load instead of as a late TypeError in warnIfNpm11NpxRisk. Add the missing 'group impact' assertion to the ai-context Cross-Repo Groups test, and a resolver-contract test.

* fix(cli): auto-select invocation path with pnpm --allow-build (#1939)
Probe npm/pnpm versions and PATH to pick a working analyze command without
user configuration: global gitnexus first, pnpm dlx with --allow-build on
npm 11+ (Ladybug native scripts), npx on npm 10 and earlier. Update docs,
skills, and tests to match the canonical install-free command.

* fix(cli): place pnpm --allow-build before dlx, repair version-injection seam (#1939)
The auto-selected install command emitted `pnpm dlx --allow-build=… analyze`,
but pnpm < 10.14 keeps `dlx` in its argv escape list, so flags placed *after*
`dlx` are parsed as package specs and rejected (ERR_PNPM_SPEC_NOT_SUPPORTED) on
pnpm 10.2–10.13.x — strictly worse than the bare command. Move the flags before
`dlx` (the position pnpm has honored since 10.2.0) in both byte-identical hook
copies, the committed AGENTS.md / CLAUDE.md, and every skill tree.
Also repairs the CI-red resolveInvocationMode seam: injecting `{ npmMajor: null }`
to simulate an absent npm fell through `??` to the host's real `npm --version`
(npm 10.x on the CI runners → routed 'npx' instead of 'pnpm'). Use an
`'npmMajor' in deps` sentinel so an injected null is honored, drop the dead
parseMajorVersion guard, and gate the flags on pnpm >= 10.2 via a single
minor-aware probeVersion spawn (skipped for committed docs). Align the TS
getNpmMajorVersion timeout to the 1s hook budget and strengthen the
skills-steering guard with a pre-dlx positive assertion plus a post-dlx
regression check.

* docs: add npm-11 pnpm caveat to README Quick Starts (#1939)
The root, package, and cursor-integration README Quick Starts still steered
first-contact users to bare `npx gitnexus analyze` — the exact npm 11.x
arborist install crash issue #1939 names as a funnel. Add a one-line pnpm
`--allow-build … dlx` caveat (keeping the simple npx default for npm<=10 /
pnpm / yarn users); the package README points to its existing npm-11
workaround section.

* docs(skills): route every gitnexus-cli command off npx to pnpm dlx (#1939)
The gitnexus-cli skill demonstrated analyze via `pnpm --allow-build … dlx`
but still showed status/clean/wiki/list via bare `npx gitnexus` — the same
package, the same npm-11 crash-prone install path — and its header claimed
"all commands work via npx". Convert every subcommand to the pnpm form across
all three skill copies and reconcile the header. Broaden the skills-steering
guard to forbid any `npx gitnexus` command in the cli-skill copies.

* perf(hook): probe pnpm once on the stale-index path (#1939)
The stale-index hook resolved pnpm twice — `which pnpm` for mode selection
then `pnpm --version` for the allow-build gate — two spawns for one tool in a
~9s/10s budget. Capture the version once in formatAnalyzeCommand and thread it
through the existing deps seam (a successful `pnpm --version` proves presence),
sharing a memoized PATH probe with resolveInvocationMode. Add explicit pnpm
10.0-suppress / 10.2-emit boundary tests and relabel the unknown-minor case.
Both byte-identical cjs copies updated together.

* fix(setup): single-quote POSIX hook command + assert cliPath patch applied (#1939)
The hook `command` written into editor settings is shell-evaluated; the
double-quoted `node "<path>"` form left `$`, backtick, and other metacharacters
live in an adversarial $HOME. Single-quote the path on POSIX (Windows keeps the
double-quoted form — those chars are illegal in Windows filenames). Also assert
the cliPath source-literal replace() actually matched, recording an actionable
error on drift instead of silently shipping a hook with an unresolved relative
path.

* test(setup): normalize expected hook path for the Windows runner (#1939)
The new POSIX-escaping test built its expected hook path with path.join,
which emits backslashes on the Windows runner, while setup.ts forward-slash-
normalizes the path before quoting — so `expect(cmd).toBe(node '<path>')`
mismatched on tests/windows-latest. Normalize the expected path the same way.
Production code was already correct; only the test's expected value was
platform-fragile.

* fix(cli): steer docs/skills via a project-local runner, not a pnpm default (#1939)
The prior approach hardcoded `pnpm --allow-build=… dlx gitnexus@latest <cmd>`
into every committed skill + the generated AGENTS.md/CLAUDE.md, which assumes
pnpm is installed. Replace it with a CLI-neutral project-local runner:
- `gitnexus analyze` drops `.gitnexus/run.cjs` (a copy of the canonical
`resolve-analyze-cmd.cjs`, which gains `buildRunnerArgv` + a `require.main`
exec tail) next to the index. Docs/skills reference `node .gitnexus/run.cjs
<cmd>`, which auto-selects the runner (global `gitnexus` → `pnpm dlx` → `npx`)
at call time — no package-manager assumption. README first-run + an inline
bootstrap note stay universal `npx gitnexus analyze`.
- The exec tail uses `shell` on Windows so `.cmd`/`.ps1`/`.exe` shims resolve
(execFileSync can't otherwise; Node blocks `.cmd` without a shell,
CVE-2024-27980), and prints a diagnostic instead of a silent exit 1.
Tests: runner exec-tail (real spawn, exit-code propagation + ENOENT diagnostic),
copy-failure graceful degradation, and per-subcommand routing + pnpm-fallback
vacuity guards. The generated CLAUDE.md block stays under the #856 token budget.

* fix(cli): resolve Windows .cmd version probes so pnpm steering fires (#1939)
probeVersion (and the TS getNpmMajorVersion mirror) spawned npm/pnpm
--version via execFileSync with no shell, so on Windows the .cmd shims
ENOENT'd, the probe reported a present tool as absent, and the stale-index
hook recommended the npx crash path #1939 exists to avoid. Add
shell: process.platform === 'win32' to the version probes (the exec tail
already does this). Parse the first version-shaped line so a Corepack/notice
banner on stdout no longer defeats the parse. Carry pnpm presence separately
from version so a present-but-unparseable pnpm still selects pnpm. Drop the
dead probe ?? resolveOnPath coalesce. Cover resolve-analyze-cmd.cjs (+ plugin
twin) with the shell-injection and windowsHide source-regression guards.

* fix(cli): widen pnpm allow-build for the --embeddings=N equals form (#1945)
buildRunnerArgv detected embeddings via gitnexusArgs.includes('--embeddings'),
which missed the equals form (--embeddings=5000) that Commander also accepts,
dropping --allow-build=onnxruntime-node on pnpm 10.2+. Match both forms.

* test(cli): cover the runner exec-tail Windows shell branch on CI (#1945)
runner-exec-tail.test.ts was POSIX-only and unregistered in
cross-platform-tests.ts, so the run.cjs Windows shell:true exec branch ran on
no platform despite the file comment claiming windows-latest covered it. Add a
.cmd-shim it.skipIf(onPosix) case and register the file in SPAWN_CLI so the
windows-latest job runs it.

* test(hooks): guard resolve-analyze-cmd.cjs in antigravity e2e sanity check (#1945)
The antigravity adapter top-level require()s resolve-analyze-cmd.cjs, but the
beforeAll helper-presence loop did not check for it — a failed copy would
surface as noisy MODULE_NOT_FOUND in downstream tests instead of the intended
actionable 'Helper not installed' error. Add it to the loop.

* docs(skills): tie a missing-runner Cannot-find-module error to recovery (#1945)
Generated CLAUDE.md/AGENTS.md make `node .gitnexus/run.cjs` the primary
command, but the runner is gitignored, so a fresh clone or git clean leaves an
agent facing a raw MODULE_NOT_FOUND. The CLAUDE.md block is token-budget-capped
(#856), so the recovery guidance lives in the cli skill (its documented home):
the bootstrap note now names the `Cannot find module` error and points at
`npx gitnexus analyze` to (re)generate the runner.

* refactor(cli): disambiguate the MCP-pinned ref from the @latest hint (#1945)
setup.ts and resolve-analyze-cmd.cjs both exported a constant named NPX_REF
with different values (version-pinned for the persisted MCP entry vs.
gitnexus@latest for hints). Rename setup.ts's module-private constant to
MCP_PINNED_REF (value and behavior unchanged — the MCP pin stays pinned),
leaving the cjs hint ref and its re-export alone. Also route the createRequire
cast through 'unknown' so it reads as an explicit narrowing to the subset this
module uses rather than a claim about the cjs's full export shape.

* fix: guide pnpm dlx/pnpx users through skipped native install
`pnpm dlx gitnexus serve` (and `pnpx gitnexus`) crash with a raw
`ERR_DLOPEN_FAILED` stack trace because @ladybugdb/core's native addon
(lbugjs.node) is placed by a postinstall script, and dlx/pnpx run
ephemerally without executing lifecycle scripts.
The existing checkLbugNative() guard already catches the missing binary
for serve/mcp/analyze, but its guidance only mentioned bun and
--ignore-scripts. Extend the message to call out the common pnpm dlx /
pnpx case and the fix (`pnpm add -g gitnexus && pnpm approve-builds -g`,
or use npx/npm). Add a matching README troubleshooting section.
This does not make `pnpm dlx` itself work — that requires a runtime
fallback in @ladybugdb/core. It turns the crash into actionable guidance.

* fix: add pnpm --allow-build dlx option to native-check guidance
Incorporates collaborator feedback (magyargergo): pnpm's security model
allows `dlx` to run build scripts when you pass `--allow-build` for each

* ci(devcontainer): retry Docker Hub syntax frontend and build

* chore: extend .gitattributes for shell scripts and binary assets
Append explicit `*.sh text eol=lf` and `*.bash text eol=lf` rules so
shell scripts (notably anything COPYed into a Linux container) check out
with LF endings on Windows hosts with `core.autocrlf=true`, regardless
of the auto-detection on the existing `* text=auto eol=lf` line. Add
binary markers for `*.node`, `*.wasm`, `*.onnx`, `*.so`, `*.dll`,
`*.dylib` so native and ML model artifacts aren't ever subjected to text
normalization.
The existing `* text=auto eol=lf` and `.husky/* text eol=lf` rules are
preserved. `git ls-files --eol` confirmed zero CRLF or mixed blobs in
the index, so no `--renormalize` was needed.
* feat(devcontainer): add cross-platform devcontainer for Claude Code, Codex, and Cursor CLIs
Add a Dev Container that pre-installs Claude Code (2.1.153, via Anthropic's
official Feature), OpenAI Codex CLI (pinned 0.134.0), and Cursor CLI alongside
the GitNexus native build chain. Opens via VS Code's Dev Containers extension
on Windows 11 (Docker Desktop + WSL2), macOS, or Linux without OS-specific
branches in devcontainer.json.
Topology and base
- Base image `mcr.microsoft.com/devcontainers/typescript-node:1-22-bookworm`
(multi-arch, monthly patched, ships the `node` non-root user, zsh, `gh`).
- Node 22 LTS satisfies `gitnexus/`'s engines `>=22.0.0` and matches the
`node:22-bookworm-slim` SHA-pinned base used by `Dockerfile.cli`.
- Single container with all three CLIs co-installed (vs. docker-compose
per-tool) — prevailing 2026 community pattern, lowest daily-driver friction.
Persistence and auth
- Per-devcontainer named volumes scoped by `${devcontainerId}` for
`/home/node/.claude`, `/home/node/.codex`, `/home/node/.cursor`,
`/commandhistory`, and `/home/node/.npm`. Authentication survives rebuilds
without leaking between workspaces.
- Four sub-workspace `node_modules` volumes (root, gitnexus, gitnexus-web,
gitnexus-shared) keep tree-sitter native bindings and onnxruntime off the
bind mount — the actual Win/Mac perf win.
- Credential mount paths are pre-created in the Dockerfile with
`chown node:node` BEFORE `USER node`, so empty named volumes inherit
correct ownership on first mount and first-run logins don't EACCES.
- `CURSOR_API_KEY` is injected via `containerEnv: ${localEnv:CURSOR_API_KEY}`
(Cursor's documented headless path); falls back to interactive
`cursor-agent login` when the host env var is unset.
Build-arg promotion
- Build args (`CLAUDE_CODE_VERSION`, `CODEX_VERSION`, `CURSOR_VERSION`, `TZ`)
are promoted to ENV in the Dockerfile so lifecycle commands and shells can
resolve them. Without this promotion, Docker ARG values are build-only and
silently no-op at lifecycle time.
Workspace setup
- `postCreateCommand` chowns the four workspace `node_modules` volumes
(Docker creates them root-owned), then installs in dependency order:
root → gitnexus-shared (install + build) → gitnexus → gitnexus-web. The
shared package must build before its consumers (`file:../gitnexus-shared`).
Ports
- 5173 (Vite dev) and 4173 (Vite preview) auto-forwarded.
- 4747 (`gitnexus serve`) marked `requireLocalPort: true` because
`gitnexus-web/src/services/backend-client.ts` hardcodes
`http://localhost:4747` as the default backend URL; a remapped port would
silently break the web UI.
VS Code integration
- Recommended extensions: `anthropic.claude-code`,
`dbaeumer.vscode-eslint`, `esbenp.prettier-vscode`, `eamodio.gitlens`.
- Settings: format-on-save with Prettier, ESLint auto-fix on save, zsh as
default terminal profile, persistent zsh history via `HISTFILE` →
`/commandhistory`.
Documentation
- `.devcontainer/README.md` covers WSL2 setup (clone inside WSL2 for IO and
file-watcher reliability), first-time auth flows for each CLI, port-
forwarding notes, LadybugDB container limitations, and the bumping
procedure for each CLI version.
- `CONTRIBUTING.md` gets a "Containerized development (optional)"
subsection pointing at the devcontainer README.
Deferred to a follow-up PR
- Opt-in egress firewall (originally planned as a fourth implementation
unit). The Dev Containers spec makes `runArgs` static — toggling
`NET_ADMIN`/`NET_RAW` capabilities cleanly requires either a separate
`devcontainer-firewall.json` profile or an `initializeCommand`-generated
overlay. Keeping this PR focused on the working baseline.
- Codespaces-specific tuning (works incidentally when the firewall is off,
not actively tested).
- Inside-container Playwright e2e (needs Chromium libs not in the base
image).
Verification deferred to user
- This change introduces a new dev tooling artifact. Validate by running
`docker build .devcontainer/`, opening the repo in VS Code via
"Dev Containers: Reopen in Container", confirming `claude --version`,
`codex --version`, `cursor-agent --version` resolve inside the container,
and `cd gitnexus && npm run test:unit` runs clean against the
named-volume `node_modules`.
* fix(devcontainer): make interactive login the default auth path for all CLIs
The previous `containerEnv` injected `CURSOR_API_KEY: "${localEnv:CURSOR_API_KEY}"`.
When the host had no `CURSOR_API_KEY` set, this resolved to an empty
string and Docker injected `CURSOR_API_KEY=""` into the container.
Cursor CLI treats a set-but-empty `CURSOR_API_KEY` as "use this key"
rather than "fall back to stored login", which silently broke
`cursor-agent login` on the most common path — users who hadn't
explicitly opted into API key auth.
Drop `CURSOR_API_KEY` from `containerEnv`. Login is now the
unconditional default for all three CLIs (Claude Code, Codex CLI,
Cursor CLI); the named-volume + Dockerfile-chown pattern keeps
credentials persistent across container rebuilds for every login path.
Reorganize the README's auth section to put login first for all three
CLIs uniformly (matching the new behavior) and move API key
authentication into a separate "Alternative" section for CI/headless
use. Document that API keys are intentionally not auto-propagated from
the host and explain the export-in-shell or VS Code dotfiles-repo paths
for users who want them. Update the troubleshooting row to reflect the
new design.
* fix(devcontainer): install gitnexus-web before gitnexus in postCreateCommand
The previous order (root → gitnexus-shared → gitnexus → gitnexus-web)
broke at the `gitnexus` install step because `gitnexus`'s `prepare`
script runs `scripts/build.js`, which compiles `gitnexus-web` whenever
its source tree exists. In the devcontainer the entire workspace is
bind-mounted, so `gitnexus-web/` is present from the start — but its
`node_modules/` wasn't yet, so `tsc -b` failed with:
error TS2688: Cannot find type definition file for 'vite/client'
error TS2688: Cannot find type definition file for 'node'
Reorder so `gitnexus-web` installs before `gitnexus`. Verified
end-to-end via `npx @devcontainers/cli up`: container builds clean,
all three CLIs (Claude 2.1.153, Codex 0.134.0, Cursor) respond, and
`npx tsc --noEmit` inside `/workspace/gitnexus` passes.
Production Dockerfiles (`Dockerfile.cli` etc.) don't hit this because
they only COPY `gitnexus/` + `gitnexus-shared/`, so `gitnexus-web/`
doesn't exist at install time and `scripts/build.js` skips the web
step. The devcontainer's full-tree bind mount changes that calculus.
* fix(devcontainer): clear stale .husky/_ before npm install
When `npm install` runs the root `prepare` script (husky), husky tries
to copyfile `node_modules/husky/husky` → `.husky/_/h`. On Docker Desktop
Windows bind mounts, if `.husky/_/` already exists from a prior
container run, the new container's `node` user can't overwrite it via
the bind mount's permission translation and the install fails with:
Error: EPERM: operation not permitted, copyfile
'/workspace/node_modules/husky/husky' -> '.husky/_/h'
Drop `.husky/_` defensively in `postCreateCommand` before `npm install`
so husky always starts from a clean slate. `.husky/_` is a husky
runtime cache (gitignored), so removing it has no effect on the repo —
husky regenerates it. No-op for WSL2-side checkouts (where this class
of bind-mount permission collision doesn't occur).
Add a troubleshooting row to `.devcontainer/README.md` covering the
manual recovery (`rm -rf .husky/_` on the host) and the long-term fix
(clone in WSL2 — Windows-side bind mounts will keep biting on this
kind of issue across rebuilds with different UID alignment).
* feat(devcontainer): bind-mount host CLI config dirs for plugin/skill/memory sync
Switch the credential/config mounts from per-devcontainer named volumes
to bind mounts of `${localEnv:HOME}/.claude`, `~/.codex`, and
`~/.cursor`. Effect inside the container:
- Authentication is shared with the host. If you've already run
`claude login` / `codex login --device-auth` / `cursor-agent login`
on the host, you're already authenticated in the container.
- Plugins, skills, agents, memory, and settings sync both ways. Install
a plugin in the container, it shows up on the host; add a custom
agent on the host, the container sees it immediately.
- All devcontainers on the host share the same CLI state, mirroring
how host shells already share it. (Per-workspace isolation of plugins
was never a stated requirement; the previous per-devcontainer named
volumes leaked nothing useful.)
Add `.devcontainer/ensure-host-config-dirs.cjs` and wire it as
`initializeCommand`. It runs on the host before container create and
guarantees `~/.claude`, `~/.codex`, `~/.cursor` exist, so Docker doesn't
reject the bind mount when a CLI has never been used on this host.
Cross-platform via Node `os.homedir()` + `fs.mkdirSync({recursive: true})`;
idempotent; no third-party deps.
Update `.devcontainer/README.md`:
- New "How CLI state is shared with your host" section explaining the
bind-mount model up front so users know their host plugins/skills/
memory carry into the container.
- Mark first-time-login section as skippable when the user is already
authenticated on the host.
- Note the high-trust escape hatch: replace the three bind mounts with
`type=volume` named volumes if the host/container trust boundary
needs to be separated (Anthropic's reference pattern for enterprise).
- Replace the obsolete "rm named volume" troubleshooting row with one
that covers EACCES/EPERM on the host-bind-mount path.
* refactor(devcontainer): address ce-code-review findings (P0 + 4 × P1 + 8 × P2 + 2 × P3)
Walkthrough resolution of the 16-finding ce-code-review on PR #1875. 15 of
16 findings applied; one (F12, Anthropic Feature floating tag) was
superseded by F6's Feature removal.
P0
- F1: WSL2 is now REQUIRED for Windows hosts, not just recommended.
${localEnv:HOME} resolves to empty string on Windows-native (no HOME env
var) — bind mounts then point at /.claude, /.codex etc. and silently
break. ensure-host-config-dirs.cjs wrote to USERPROFILE-derived paths
via os.homedir(), so the two surfaces disagreed about which env var was
"home" on Windows. README header reframed; "Windows 11 — WSL2 is required"
section explains the mismatch concretely.
P1
- F2: Workspace `node_modules` volume names now include `-${devcontainerId}`
so two GitNexus checkouts on the same host (~/work/GitNexus and
~/projects/GitNexus) don't share volumes and corrupt each other's
installs.
- F3 + F5: `postCreateCommand` extracted to `.devcontainer/post-create.sh`
with `set -euo pipefail` and six labeled echo steps so failure logs
name the step instead of an opaque &&-chain index. Chown step extended
to cover /home/node/.npm, /commandhistory, and /home/node/.local — these
named-volume mount points were owned by build-time UID 1000 but the
container's `node` is re-IDed at runtime by updateRemoteUserUID on
non-1000 Linux hosts, leaving them unwritable until now.
- F4: Cursor installer downloaded to a temp file with curl --retry +
--max-time; sha256 logged to build output before execution so drift
across rebuilds is visible in CI logs. Full hard-pin (to a versioned
downloads.cursor.com tarball with verified sha256) tracked as a
follow-up in README "What's not included".
P2
- F6: Anthropic Feature replaced with a direct
`npm install -g @anthropic-ai/claude-code@${CLAUDE_CODE_VERSION}` so
CLAUDE_CODE_VERSION actually pins the installed binary (the Feature
ignored the ARG and pulled latest at install time). Honors the
earlier "pin known-good versions" decision and resolves F12's
floating-tag concern for this Feature.
- F7: Dockerfile ARG defaults dropped for the three version vars;
`devcontainer.json` `build.args` is now the single source of truth.
Standalone `docker build .devcontainer/` must pass --build-arg.
- F8: ensure-host-config-dirs.cjs deleted; `initializeCommand` now uses
POSIX `mkdir -p` + `touch ~/.gitconfig` directly, dropping the
host-Node-on-PATH prerequisite that broke on fresh Windows+Docker
Desktop installs without Node.
- F9: ~/.gitconfig bind-mounted read-only so `git commit` inside the
container uses the host's user.name / user.email. Read-only so
container-side `git config --global` doesn't leak to host.
- F10: ~/.config/gh bind-mounted (read-write) so `gh pr create` /
`gh pr checks` / `gh issue create` work inside the container without
re-auth. AGENTS.md's commit + PR workflow now fully functional for
agents inside the container.
- F11: CLAUDE_CONFIG_DIR removed from Dockerfile ENV; canonical value
lives only in devcontainer.json containerEnv. Eliminates the two-file
edit risk.
- F13: Mounts comment now documents per-instance vs per-workspace-name
scoping rationale so future contributors don't guess.
- F14: README "Trust boundary, concretely" paragraph names the exfil
path explicitly (malicious npm postinstall → OAuth tokens →
~/.claude/projects/<workspace>/memory/MEMORY.md secrets) and lists
vendor-side rotation runbook entries.
P3
- F15: Dockerfile pre-create + chown of /home/node/.claude, .codex,
.cursor dropped — those paths are bind-mounted, which fully shadows
any image-side ownership. Only .npm, .local, /commandhistory still
benefit from the pre-create.
- F16: README "Bumping CLI versions" section rewritten against the
post-F6 reality: CLAUDE_CODE_VERSION and CODEX_VERSION are real
pins; CURSOR_VERSION is informational only.
Verified locally: `docker build .devcontainer/ --build-arg ...` succeeds.
Smoke-tested image: `claude --version` (2.1.153), `codex --version`
(0.134.0), `cursor-agent --version` all resolve as the non-root `node`
user; named-volume mount points (/home/node/.npm, /commandhistory) are
node-owned at build time so non-1000 host UIDs get the post-create.sh
chown fix instead of EACCES.
* fix(devcontainer): cross-platform initializeCommand + soften Windows-native posture
The previous commit's `initializeCommand` was POSIX-only (`mkdir -p $HOME/...`).
VS Code on Windows runs the host shell as `cmd.exe /c ...`, which can't
parse POSIX syntax — `$HOME` doesn't expand, `mkdir -p` errors, the init
fails with `The syntax of the command is incorrect`, and container
creation aborts before Docker is invoked.
Switch `initializeCommand` to the spec's OS-keyed object form:
- linux/darwin (covers WSL2 because VS Code runs initializeCommand in
the WSL shell when attached via the WSL extension): POSIX mkdir+touch,
as before
- win32: PowerShell snippet that creates the same directories under
$USERPROFILE and touches the gitconfig if missing
Soften the README's hard "WSL2 required" framing from the previous
commit. Reality per `@devcontainers/cli read-configuration` output:
`${localEnv:HOME}` on Windows-native resolves to `C:\Users\<name>`
(VS Code falls back to USERPROFILE), so the bind mount sources are
valid Windows paths and Docker Desktop handles the translation. The
earlier `accessing specified distro mount service` failure was a
separate Docker Desktop WSL-integration issue, not a HOME-resolution
issue. Windows-native works; it's just slower with more bind-mount
permission edge cases (the husky/_/h EPERM class). The README now
explains the tradeoff and steers toward WSL2 for performance + file
watchers + permission reliability, rather than blocking Windows-native
checkouts outright.
Update the troubleshooting row to reflect the new posture.
* fix(devcontainer): Node-based initializeCommand; bind-mount .ssh + .config/git
Two fixes bundled:
1. The previous commit's OS-keyed `initializeCommand` object was based
on a misread of the Dev Containers spec. The object form on command
properties is **named parallel tasks**, not OS dispatch — VS Code ran
all three keys in parallel via cmd.exe on Windows, the POSIX branches
failed, and container creation aborted before Docker was invoked.
Restore the single-string Node-based form:
`node .devcontainer/ensure-host-config-dirs.cjs`. Node works
identically in cmd.exe on Windows and bash/zsh on Linux/macOS/WSL,
and `os.homedir()` respects $HOME on POSIX and %USERPROFILE% on
Windows. The script is idempotent (mkdirSync recursive is a no-op
for existing dirs; touch is gated on .gitconfig existence).
Document Node ≥18 on the host as the only host-side prerequisite
beyond Docker Desktop and the VS Code Dev Containers extension.
Anyone running Claude Code on the host already has it.
2. Extend the host-bind mount surface with `~/.ssh` and `~/.config/git`,
both read-only:
- `~/.ssh` lets commit signing + push over SSH remotes work inside
the container without copying private keys. Read-only mount means
container code can read keys but can't modify or delete them.
(Threat: a malicious dep can still read private keys from inside
the container; the read-only mount narrows write-side blast
radius, not read-side. Documented in the trust-boundary section.)
- `~/.config/git` covers XDG-style git config (`~/.config/git/config`,
`~/.config/git/ignore`, `~/.config/git/attributes`) for users who
keep settings there instead of `~/.gitconfig`. Read-only, same as
`~/.gitconfig`.
Update the CLI-state-sharing table and trust-boundary paragraph to
reflect the expanded surface.
Re-adds .devcontainer/ensure-host-config-dirs.cjs (deleted before the
OS-keyed attempt).
* fix(devcontainer): fail-fast on Windows-native with HOME-not-set diagnostic
The previous commit's "Windows-native works" softening was wrong. VS Code
on Windows-native resolves `${localEnv:HOME}` by reading the host shell's
HOME env var, and cmd.exe has no HOME set — the bind sources collapse to
`/.claude`, `/.codex`, etc., and Docker errors:
Error response from daemon: invalid mount config for type "bind":
bind source path does not exist: /.claude
The @devcontainers/cli output that prompted the softening was misleading
because I ran it from a Bash session with HOME already set, not from VS
Code's cmd.exe call context. The original Finding-1 P0 — that Windows-
native silently breaks the bind-mount feature — was correct.
Three changes:
1. `ensure-host-config-dirs.cjs` detects the failure mode early:
`if (process.platform === 'win32' && !process.env.HOME)` prints a
targeted error message naming the root cause (cmd.exe has no HOME →
${localEnv:HOME} resolves empty → bind sources fail) and a step-by-step
pointer to set up WSL2. Exits 1 so VS Code surfaces it as a clean
container-creation failure, not the cryptic Docker bind-mount error.
2. README header reverted to "Windows 11 via WSL2" only (not "and
Windows-native"). The "Windows 11 — WSL2 is required" section names
the specific HOME-resolution mismatch concretely so future readers
understand why the constraint exists.
3. Troubleshooting table gets a new row for the `ERROR: GitNexus
devcontainer requires WSL2` message pointing at the setup section.
* feat(devcontainer): support Windows-native via auto setx HOME on first run
Reverses the "WSL2 required on Windows" posture. Windows-native now
works after a one-time auto-handled setup.
The root cause of the bind-mount failure: VS Code resolves
`${localEnv:HOME}` by reading its own process env, and Windows doesn't
set `HOME` by default — Windows uses `USERPROFILE`. So the bind sources
were collapsing to `/.claude`, `/.codex`, etc., and Docker rejected them.
`ensure-host-config-dirs.cjs` now handles this automatically on Windows
hosts where `HOME` is unset:
1. Runs `setx HOME "%USERPROFILE%"`, which writes to the user-level
Windows environment (HKCU\Environment) — no admin required. Every
future user process inherits HOME from there.
2. Prints a clear one-time setup banner explaining the user needs to
fully restart VS Code (File > Exit, not just close the window) for
VS Code to pick up the new env at its next startup.
3. Exits 1 so VS Code surfaces this as a clean container-create failure
instead of letting Docker error opaquely later.
On the second Reopen-in-Container attempt, `HOME` is now set in VS
Code's env, the script skips the setup block, creates the bind-mount
source dirs, and the container builds normally. Subsequent rebuilds
have no extra steps.
Mac, Linux, and WSL2 hosts have `HOME` set by the shell, so the new
block is a no-op there. Same `devcontainer.json` works across all
supported hosts.
README rewritten to reflect the new posture:
- Header lists Windows 11 (native) as a supported host alongside macOS,
Linux, and WSL2, with a note that Windows-native gets a one-time
HOME setup handled by the initializeCommand.
- New "Windows 11 setup" section walks through the auto-handled setup
flow + a manual `setx HOME "%USERPROFILE%"` fallback for users who
want to do it themselves.
- "Known trade-offs of Windows-native vs WSL2" subsection lays out the
Docker Desktop Windows bind-mount edge cases (file watchers, npm
install perf, husky/_ EPERM) so users opting into Windows-native do
so eyes-open. WSL2 remains documented as the faster path for users
who want it, but it's no longer the only supported one.
- Troubleshooting table gets two new rows: the one-time setup banner
(with "what to do" instructions) and the residual `bind source path
does not exist` case (run setx manually + fully exit VS Code).
* fix(devcontainer): drop ~/.gitconfig bind mount; defer to VS Code auto-copy
VS Code's Dev Containers extension auto-copies the host's gitconfig into
the container at attach time using `(dd ...) >> /home/node/.gitconfig`.
A read-only bind mount of ~/.gitconfig blocks that write, so attach
failed with `cannot create /home/node/.gitconfig: Read-only file system`.
Making it read-write would let the append succeed, but the bind mount
means the host file and the container file are the same file — VS Code's
append would double the host gitconfig contents on every container
start.
Drop the ~/.gitconfig bind mount entirely. VS Code's auto-copy is the
purpose-built mechanism for this, gives the container the host's
user.name / user.email transparently, and avoids both the read-only
write failure and the append-duplication trap. The container ends up
with a writable /home/node/.gitconfig that's a copy of the host's, not
a mount.
The remaining six bind mounts (.claude, .codex, .cursor, .ssh, .config/git,
.config/gh) keep their existing modes — XDG-style git config under
~/.config/git is unaffected by VS Code's auto-copy (which only targets
~/.gitconfig), so its read-only bind mount stays.
Also remove the `.gitconfig` touch from ensure-host-config-dirs.cjs
(now unnecessary) and update the README CLI-state table, sharing
explanation, and troubleshooting row to reflect that gitconfig flows
in via VS Code auto-copy rather than the bind mount.
* feat(devcontainer): bind-mount ~/.docker, ~/.aws, ~/.azure for agent workflows
Extend the host bind-mount surface so coding agents inside the container
inherit cloud + container-registry auth from the host without any
per-container setup:
- ~/.docker (read-write) — Docker registry auth (config.json) + buildx
config. Container-registry pushes (ghcr.io, docker.io) from inside the
container pick up host `docker login` state. Read-write because the
Docker CLI refreshes credential-helper tokens.
- ~/.aws (read-only) — AWS CLI / SDK credentials. Read-only because
rotating creds typically happens via the host. Empty on this dev box,
so forward-compatible: the moment you `aws configure` on the host the
container picks it up on the next rebuild.
- ~/.azure (read-only) — Azure CLI credentials. Same pattern as ~/.aws.
`ensure-host-config-dirs.cjs` extends to mkdir these three on init so
the bind mounts always have a valid source even if a CLI has never been
used on this host.
The Docker CLI itself isn't installed in the container by default — the
~/.docker/ mount is inert until you add `docker-outside-of-docker:1` or
similar Feature. README now calls this out under "What you still don't
have inside the container" so it's obvious which CLIs are agent-ready
and which need a feature add to become useful.
README updates:
- Bind-mount table gains a "Why" column and rows for the three new
mounts, making it clear at a glance what each one enables.
- Trust-boundary section lists Docker registry tokens, AWS, and Azure
creds in the read-side exfil path so the threat model stays honest as
the credential surface grows.
- New subsection lists not-included CLIs (Docker, AWS, Azure, gcloud,
kubectl, private-npm) with the exact Feature ID or mount snippet
needed to enable each — turns "I want my agent to do X" into a
one-line config change.
Verified locally: `npx @devcontainers/cli read-configuration` resolves
all 9 host bind mounts to valid C:\Users\<name>/* paths on Windows.
* refactor(devcontainer): hybrid AI CLI config — read-only host share + per-container credentials
Restructure the Claude Code / Codex / Cursor mount topology to fix the
silent first-run-UI bug surfaced in PR testing, and to harden against
the host-write-through escape class the previous bind-mount design
exposed.
The actual root cause of the first-run wizard firing on the user's
screenshot — confirmed via three parallel research agents (best
practices, framework docs deep dive of the OpenAI Codex Rust source,
adversarial design review) — was NOT a credential permission check.
Claude Code splits state across `~/.claude/.credentials.json` AND
`~/.claude.json` (a FILE at $HOME, sibling of the `.claude/` dir).
The latter holds `hasCompletedOnboarding`, `userID`, `oauthAccount`
metadata, MCP user-scope config, and per-project trust state — and
Claude Code reads it at literal `$HOME/.claude.json`, not via
`CLAUDE_CONFIG_DIR`. The previous design mounted `~/.claude/` but
left `~/.claude.json` outside the topology entirely, so every container
started with a missing onboarding-state file and re-ran the wizard.
Confirmed by tfvchow/field-notes-public#10:
"Persisting .credentials.json alone is NOT sufficient. Without
.claude.json, Claude Code treats the session as a fresh install and
prompts for login regardless of valid credentials being present."
The new topology:
**Mounts**
- `${localEnv:HOME}/.claude` → `/host/.claude` (read-only bind)
- `${localEnv:HOME}/.codex` → `/host/.codex` (read-only bind)
- `${localEnv:HOME}/.cursor` → `/host/.cursor` (read-only bind)
- `${localEnv:HOME}/.claude.json` → `/host/.claude.json` (read-only bind)
- `claude-config-${devcontainerId}` → `/home/node/.claude` (named volume)
- `codex-config-${devcontainerId}` → `/home/node/.codex` (named volume)
- `cursor-config-${devcontainerId}` → `/home/node/.cursor` (named volume)
**containerEnv** gains `CODEX_HOME=/home/node/.codex` (Codex's own env
override, per its public Rust source). `CLAUDE_CONFIG_DIR=/home/node/
.claude` was already set.
**`post-create.sh`** stages the named volumes on first run:
- Symlinks shareable subdirs from `/host/.claude` into the named volume:
`plugins/`, `skills/`, `agents/`, `memory/`, `commands/`. Codex gets
`config.toml` symlinked. Cursor has no shareable subdirs (cli-config
.json conflates auth and settings).
- Copies `.credentials.json`, `auth.json`, `cli-config.json` on first
run with `chmod 600`. After first run, container manages its own
refresh; host's credentials untouched.
- Copies `~/.claude.json` on first run (with stub
`{"hasCompletedOnboarding":true,"installMethod":"global"}` fallback
for hosts that haven't run Claude Code). This is the fix for the
observed onboarding-wizard loop.
`ensure-host-config-dirs.cjs` now also touches `~/.claude.json` on the
host if missing, so the bind mount has a valid source on hosts that
have never run Claude Code.
**Why read-only + named volume vs. the previous full bidirectional
bind mount:**
1. **Host filesystem write-through escape, eliminated.** Previous
design symlinked `plugins/`, `agents/`, `skills/` write-through
into the host's `~/.claude/` — a malicious npm package in the
workspace dep tree could drop `agents/evil.md` into the host's
config, which the next host Claude session would auto-load. The
read-only `/host` mount blocks this; container compromise no
longer persists across teardown via host-side autoload.
2. **Windows bind-mount perm-flattening, sidestepped.** Files
surfaced through a Docker Desktop Windows bind mount appear as
`root:root` mode `777`. Credentials in the named volume come with
proper Linux ownership and `chmod 600` — what each CLI expects on
write (none enforces on read, but write-side hygiene matters for
the host's understanding of "where credentials live").
3. **No `ide/` lock-file collisions.** Previous design symlinked
`~/.claude/ide/` write-through, including per-PID lock files. Host
PID and container PID namespaces are unrelated → lock-file PIDs
misclassify dead processes as alive. Skipping `ide/` keeps lock
files container-local.
4. **No `projects/` ghost dirs.** Host encodes the workspace path as
`D--development-coding-GitNexus`, container as `-workspace`.
Bidirectional `projects/` symlinks would split memory and session
state across two ghost project dirs for what is conceptually the
same project. Skipping `projects/` keeps per-project state
container-local; host's projects/ stays untouched.
5. **No `settings.json` version drift.** Container is pinned to a
specific Claude Code version (`CLAUDE_CODE_VERSION` build arg);
host floats with auto-update. Bidirectional `settings.json` writes
produced silent schema rollback. Skipping settings.json keeps each
side authoritative for its own version.
**README** rewritten in the same section to describe the new topology
honestly: what's shared, what isn't, the OAuth refresh-token
divergence between host and container, per-CLI quirks (macOS Keychain
storage, Cursor's known upstream in-container auth bug, Codex
keyring storage). Trust-boundary section updated to name the threat
model accurately — same read surface as before (malicious dep can
still READ all credentials), but write-through into host plugin/agent
dirs is now blocked.
Verified locally: `@devcontainers/cli read-configuration` resolves all
19 mounts correctly on Windows, `post-create.sh` parses, and
`ensure-host-config-dirs.cjs` idempotently touches `~/.claude.json`.

* fix(devcontainer): resync AI CLI state from host on every container-create
Two bugs were causing Claude Code to fire the onboarding wizard inside the
container even with valid host credentials:
1. Missing the second state file. Claude Code 2.1.x writes a small `.claude.json`
INSIDE `CLAUDE_CONFIG_DIR` (carrying migration tracking + userID), not just the
one at `$HOME/.claude.json`. If the userIDs in the two files disagree, Claude
treats the session as inconsistent and re-onboards. The previous post-create.sh
only copied the `$HOME` one.
2. First-run guards (`[ ! -e $dst ]`) skipped the copy when stale named volumes
from earlier rebuilds still had the prior session's state in them, leaving the
container desynced from the host.
Replace `copy_on_first_run` with `sync_from_host` that always overwrites from
host on container-create. `link_readonly_share` now clears stale non-symlink dst
entries before linking. Copies both `$HOME/.claude.json` and
`$CLAUDE_CONFIG_DIR/.claude.json` so userIDs stay aligned. Container can still
mutate its own state between rebuilds; resync only happens on rebuild
(postCreate boundary).
* docs(devcontainer): document sync-from-host design + dual-source auth flow
README still described the old "first-run copy" behavior. After the
post-create.sh change to always-sync-from-host, the design works either
direction:
- Log in on host → next container-create syncs the credentials into the
named volume.
- Log in inside the container → the named volume persists the login across
rebuilds; the host has no source to overwrite from, so it stays alone.
Also documents the two-Claude-state-files trap (`$HOME/.claude.json` AND
`$CLAUDE_CONFIG_DIR/.claude.json`, both with the same userID required), and
the volume-deletion recovery path for stale named volumes carried over
from earlier rebuilds.
* fix(devcontainer): full plugin/config parity by dropping CLAUDE_CONFIG_DIR + syncing settings.json
Two changes that together give the container the same plugins and configs
as the host for all three AI CLIs (login stays per-container):
1. Drop CLAUDE_CONFIG_DIR from containerEnv. The named-volume mount target
`/home/node/.claude` already matches Claude's default `~/.claude`, so
the env var added no behavior — but setting it changed which file
Claude reads `hasCompletedOnboarding` from. With it set, Claude reads
`$CLAUDE_CONFIG_DIR/.claude.json` (the small identity-only file that
does NOT carry `hasCompletedOnboarding`); without it, Claude reads
`$HOME/.claude.json` (the big onboarding-state file that does). The
wizard fires every container-create when set, skips when unset.
2. Sync `settings.json` from host (Claude) + symlink `memories/` and
`skills/` from host (Codex). Theme + `enabledPlugins` +
`extraKnownMarketplaces` live in `settings.json` — without syncing
it, the theme picker fires and host-installed plugins stay disabled
even though their files are symlinked in. Codex's `memories/` and
`skills/` are the symmetric Codex user-installed surface, now shared
the same way Claude's plugins/skills/agents/memory/commands are.
Cursor stays as-is — `cli-config.json` conflates auth+settings (already
synced), and there's no separate plugin surface to mirror.
Login details remain per-container by design (acceptable to re-login on
rebuild). Everything else — plugins, skills, agents, memory, MCP user-
scope config, project trust, theme, plugin enablement — now matches
host on every container-create.
* refactor(devcontainer): hybrid RW bind + per-container creds — fixes EROFS on in-container plugin install
The previous Option B topology (RO host stage + named volume + symlinks
into the volume) made `/plugin marketplace add` inside the container fail
with EROFS — the symlinks pointed at a read-only mount, so Claude
couldn't create new marketplace dirs. Switch to a hybrid: shareable
content (plugins/skills/agents/memory/commands/settings.json/$HOME/.claude.json
for Claude; config.toml/memories/skills for Codex) gets a direct RW bind
from host so reads and writes go bidirectionally; credentials + the
small identity file stay in per-container named volumes so logout in
container doesn't log out host.
Mount precedence does the heavy lifting: the named volume mounts at
/home/node/.<cli> first, then sub-path bind mounts overlay specific
sub-paths. Container's view at /home/node/.claude/plugins/ is the host
dir; container's view at /home/node/.claude/.credentials.json is the
named volume's file.
What this gives you:
- /plugin marketplace add in container = installed on host
- New skill on host = visible in container immediately (no rebuild)
- claude logout in container = host stays logged in
- compound-engineering plugin enabled on host = enabled in container
- Theme picker fires once (or never if host has theme set)
What it costs:
- Write-through: a compromised npm dep in workspace deps can write to
host ~/.claude/{plugins,skills,agents,memory,commands}/. Documented
trade-off; for personal dev, accepted. Credentials still per-container.
post-create.sh becomes much simpler — only syncs the four credential
files from host into the named volumes. No more symlink dance, no more
state-file merging.
ensure-host-config-dirs.cjs gains the new bind sources: the shareable
subdirs and settings.json/config.toml files get mkdir/touched on host
so Docker doesn't reject the mount when a CLI has never been used.
* fix(devcontainer): translate host plugin registry paths to Linux on rebuild
The previous topology bind-mounted the entire `~/.claude/plugins/`
directory from host. That brought through plugins, marketplaces, and
extracted cache content correctly — but ALSO brought through the
registry JSONs (`known_marketplaces.json`, `installed_plugins.json`,
`plugin-catalog-cache.json`) which carry absolute OS-native paths:
"installLocation": "C:\Users\gergo\.claude\plugins\marketplaces\X"
"installPath": "C:\Users\gergo\.claude\plugins\cache\Y\Z"
Claude in the Linux container fails to resolve these Windows paths and
reports `Marketplace X failed to load: cache-miss`.
Split the topology:
- `plugins/marketplaces/` (git clones) and `plugins/cache/` (extracted
plugin files) stay bidirectional RW binds — content is path-independent.
- Registry JSONs move into the per-container named volume. post-create.sh
reads host's versions, rewrites any absolute path ending in
`/.claude/plugins/<rest>` (Windows `C:\Users\...` and POSIX
`/Users/...` / `/home/...` patterns) to `/home/node/.claude/plugins/<rest>`,
and writes the translated result to the volume.
What this gets you:
- Plugin installed on host → next container rebuild has it (translated).
- Plugin installed inside container → lives in volume registry; lost on
rebuild (consistent with credentials model). Re-install on host for
persistence.
ensure-host-config-dirs.cjs now also creates `plugins/marketplaces/` and
`plugins/cache/` on host if absent (Docker rejects bind mounts whose
source doesn't exist).
* fix(devcontainer): clean stale plugin/skill symlinks from prior design before writes
A user upgrading from Option B (read-only host stage + symlinks) to the
current hybrid RW-bind topology hit EROFS in post-create.sh when the
plugin registry path-translator tried to write
`/home/node/.claude/plugins/known_marketplaces.json`. The named volume
still carried `/home/node/.claude/plugins -> /host/.claude/plugins`
(Option B's symlink). The new design's sub-path bind mounts at
`plugins/marketplaces` and `plugins/cache` overlay through the symlink,
but writes to the parent dir itself resolve via the symlink to the RO
host stage and fail.
Drop any leftover symlinks at known target paths early in step 2 so the
mkdir/writes that follow land in the volume.
* refactor(devcontainer): split workspace-deps to updateContentCommand
post-create.sh was doing two unrelated jobs: workspace dependency install
(four `npm install` runs in topological order) and AI CLI credential
sync. They have different lifecycle needs — deps should re-run when
lockfiles change, AI sync should run once per container — but both were
gated on container-create.
Per Dev Container spec lifecycle, `updateContentCommand` is the right
hook for workspace deps: runs at container-create AND on content
changes (lockfile updates). `postCreateCommand` is right for AI CLI
sync: container-create only.
Move steps 3-7 (husky cleanup + four `npm install` runs) into
install-deps.sh wired as `updateContentCommand`. Split the chown step
too — install-deps owns workspace-side dirs (node_modules volumes,
~/.npm), post-create owns AI-side dirs (~/.claude, ~/.codex, ~/.cursor,
/commandhistory, ~/.local). Each script now has one concern.
post-create.sh drops from ~187 lines to 148; install-deps.sh is 56 lines
new. Faster rebuilds when nothing about deps changed (the credential
sync + path translation work still runs every container-create, but the
npm install dance no longer does).
Research backing (no other simplification applies):
- Anthropic's reference devcontainer uses pure named volumes; no
host-state inheritance pattern is published.
- Path translation has no upstream fix (issues #21916, #10379 closed
without resolution). Our Node rewrite is the workaround.
- pnpm workspaces (`pnpm -r install`) would replace the four installs
with one command, but that's a real refactor (touches
gitnexus/scripts/build.js + 4 package.json files); deferred.
- `HUSKY=0` in containerEnv would drop the `rm -rf .husky/_` hack, but
would also stop pre-commit hooks from firing inside the container;
deferred.
* fix(devcontainer): drop single-file binds — fixes Codex `batchWrite failed in TUI`
On Docker Desktop Windows the named volumes are ext4 (`/dev/sdd`) while
single-file bind mounts from the Windows host land as 9p (drvfs).
Different filesystems → atomic config writes (write `foo.tmp`, then
rename onto `foo`) trip EXDEV `inter-device move failed` /
`Device or resource busy`.
Codex's TUI surfaces this as `config/batchWrite failed in TUI` when
saving model preference. Claude's writes to settings.json / .claude.json
fail the same way, silently.
Reproduction in container:
$ echo x > /tmp/foo.toml; mv /tmp/foo.toml /home/node/.codex/config.toml
mv: inter-device move failed: ... Device or resource busy
Fix: drop the three single-file bind mounts. Sync host's versions into
the named volume on container-create via `sync_from_host` (same pattern
already used for credentials). Atomic rename within the volume works
because everything is ext4.
Trade-off: container writes to these files no longer propagate to host;
they stay in the volume until next rebuild, which re-syncs from host.
Host is source of truth on rebuild — same model as credentials. Plugin/
skill/agent/memory/command DIRS still bind-mount bidirectionally (atomic
writes within a dir bind stay on one filesystem, no EXDEV).
Files affected:
- ~/.codex/config.toml
- ~/.claude/settings.json
- ~/.claude.json (HOME-level — added `/host/.claude.json` RO mount back
for sync_from_host to read)
* chore(autofix): apply prettier + eslint fixes via /autofix command
* feat(devcontainer): Codex + Cursor plugin/config host parity with Claude
Codex plugins installed in the container never reached the Windows host
because, unlike Claude, the Codex plugin tree wasn't bind-mounted —
only memories/ and skills/ were. Verified via live /proc/mounts: Claude
binds 6 shareable dirs (incl. plugins/marketplaces + plugins/cache),
Codex bound 2. So `codex plugin add` wrote into the ext4 named volume
and stayed there.
Codex changes:
- Bind the WHOLE ~/.codex/plugins dir + ~/.codex/prompts (plus existing
memories/skills). Strace of two real `codex plugin add` runs proved
the installer stages INSIDE plugins/cache/<marketplace>/ and renames
intra-dir, so a single 9p bind of plugins/ keeps the rename intra-fs —
no EXDEV (the bug that broke single-file binds). .tmp/ stays on the
volume (it's the cross-fs staging source). No path translation needed:
Codex enablement lives in config.toml as git URLs, not FS paths.
- Verified live: `codex plugin add compound-engineering@...` now writes
through to C:\Users\...\.codex\plugins\cache\ on the Windows host, and
host-created files appear in the container (bidirectional).
Cursor changes (review found cursor-agent has a real plugin surface, not
editor-only — Cursor 2.5 Marketplace shared by IDE + CLI):
- Bind plugins/marketplaces, plugins/local, rules, commands, agents,
skills (dir binds, EXDEV-safe).
- Copy-on-create mcp.json (single file → EXDEV-unsafe as bind), alongside
the existing cli-config.json.
- Translate plugins/installed_plugins.json (carries absolute Windows
paths like Claude's) — generalized the existing path-rewrite to run
for both Claude and Cursor.
- hooks.json deliberately NOT shared (runs shell commands → supply-chain
surface); documented as opt-in.
ensure-host-config-dirs.cjs pre-creates all new host bind sources.
post-create.sh defensive symlink cleanup extended to the new Codex/Cursor
paths. README updated with the accurate per-CLI share/sync/translate
matrix.
Design adversarially verified (straced installs, EXDEV primitive tests,
sqlite-under-bind check, path-encoding check) before implementing.
* fix(devcontainer): resolve ce-code-review findings (doc drift, chown scope, .cjs extraction, CI smoke)
Multi-agent review (9 reviewers) found the devcontainer files carried
comments + README from the abandoned read-only-symlink design, plus real
behavioral gaps. Resolved all actionable findings (no deferrals).
Documentation drift (the headline — stale comments described a security
model opposite to what shipped):
- README "Trust boundary" claimed a malicious dep "cannot write back …
the read-only /host mount blocks the write." FALSE — the shareable dirs
are RW-bound. Rewrote to document the bidirectional write-through, what
stays one-way (credentials never flow back), and how to close it.
- devcontainer.json mount group-1 comment described "selectively symlinks
… read-only eliminates write-through" — replaced with the RW-bind reality.
- Header "Windows-native is unsupported" -> supported (auto HOME setup).
- containerEnv comment "credentials persist in host-bind-mounted dirs" ->
they live in the named volumes.
- hooks.json exclusion documented honestly as a partial mitigation, not a
clean boundary (commands/agents/skills/rules are equally executing).
- ~/.local "named volume" -> image directory.
Behavioral fixes:
- chown -R recursed into the RW host binds (could rewrite host ownership /
EPERM-abort provisioning on non-UID-aligned Linux). Switched to
`find -xdev` per dir so chown stays on the volume filesystem.
- Cursor installer wrapped in `timeout 300` — its inner binary download
isn't covered by curl --max-time and could hang docker build forever.
- Removed dead CURSOR_VERSION ARG/ENV/build-arg (never consumed; "latest"
implied a pin the installer can't honor). Documented why Cursor is unpinned.
Extraction + tests (the two inline post-create.sh node heredocs were
unlintable and untestable; the path regex had had bugs):
- seed-claude-config.cjs — installMethod-strip seed, now with a non-object
guard (a bare-value/array host .claude.json could otherwise slip the
try/catch and silently re-trigger onboarding) and labeled write errors.
- translate-plugin-registries.cjs — plugin-registry path translation with
labeled errors.
- translate-plugin-registries.test.cjs — 12 tests (Windows/POSIX paths,
cross-CLI isolation, nested objects, non-object/empty-config guard).
- post-create.sh calls the modules via $SCRIPT_DIR.
CI:
- .github/workflows/ci-devcontainer.yml — runs the unit tests + shell
syntax checks + a `@devcontainers/cli build` smoke on .devcontainer/**
changes. Conforms to the repo concurrency convention (validator passes).
Documented (real gaps, fixes are honest docs since no correct auto-fix
exists): user-scope MCP servers with absolute host command paths don't
resolve in-container; user-scope config is copy-on-create so host edits
need a rebuild; in-container plugin installs get shadowed by an empty host
bind on rebuild (recovery noted); plugin installs are single-writer across
checkouts; gh/docker RW-vs-ssh/aws/azure-RO rationale.
Verified: fresh `@devcontainers/cli up` succeeds; installMethod stripped,
registry translated to Linux paths, credentials node:node, 12/12 tests pass.
* fix(devcontainer): set persist-credentials:false on CI checkouts + prettier
- zizmor `artipacked` (CodeQL/GitHub Advanced Security) flagged both
actions/checkout steps in ci-devcontainer.yml: checkout defaults to
persist-credentials:true, leaving GITHUB_TOKEN in .git/config where it
can leak into uploaded artifacts. Both jobs are read-only (run tests /
build smoke, never push), so persist-credentials:false is correct —
matches the repo convention in codeql.yml / ci-tests.yml.
- Ran prettier 3.8.0 over the new .cjs modules + test (single-quote/style
normalization to match the repo). JSON/YAML were already compliant;
README is in .prettierignore; .sh has no prettier parser. Behavior
unchanged — 12/12 transform unit tests still pass.
* fix(devcontainer): resolve adversarial review findings (pins, RO mounts, tests)
Resolves the blocking + actionable findings from the PR #1875 review:
- Pin base image by digest as bare name@digest [#1]. The :tag@digest form
trips the @devcontainers/cli image-name parser (which builds this image
in CI and in VS Code "Reopen in Container"); bare name@digest is the
parser-compatible form. Verified by a full local build.
- Pin Cursor by version + per-arch sha256 and fetch the artifact directly
instead of executing cursor.com/install; fail-closed on mismatch [#2].
- Mount ~/.config/gh and ~/.docker read-only so a compromised dep can't
rewrite the host GitHub token / Docker credHelper [#4].
- Pin @devcontainers/cli@0.87.0 in the CI smoke [#5].
- chown via find -xdev in install-deps.sh (symlink-safe; matches
post-create.sh) [#6].
- Add filesystem-I/O tests (translate/readHostConfig/seed main/ensurePaths)
and refactor ensure-host-config-dirs to be unit-testable [#7].
- Stop pre-creating settings.json/config.toml on the host; only the real
single-file bind source (.claude.json) is touched [#10].
- Add a prominent top-of-README security callout for the RW write-through
trade-off and reframe the deferred egress firewall as the key missing
compensating control [#3, #9].
Full devcontainer build verified locally (digest pull + pinned Cursor
download/extract/symlink). 24/24 config-transform tests pass.
* fix(devcontainer): resolve local adversarial-review findings (low/nit)
Follow-up to a local branch review (run after the cloud review crashed before
producing findings); all 5 confirmed findings were low/nit:
- chown via `find -xdev -exec chown -h`: add -h so chown acts on a symlink
ITSELF, not its target. Without it a dangling node_modules/.bin link aborted
provisioning under `set -e`, and a cross-fs symlink target could be
dereferenced/rewritten. Verified in a clean container (regular files still
chowned; dangling link no longer aborts; cross-fs target untouched). Applied
to install-deps.sh and post-create.sh; the inline comments are corrected to
describe -xdev (descent bound) and -h (no deref) as the two distinct guards.
- Reword the .cjs header claims from "lintable" to "unit-tested and
prettier-checked": ESLint applies no rules to .cjs in this repo; CI only
prettier-checks them.
- README: the initializeCommand is `node ensure-host-config-dirs.cjs`, which
creates the full bind-source set, not a bash `mkdir -p` of four dirs.
- ci-devcontainer.yml: document that the x64 runner exercises only the amd64
Cursor branch; the arm64 sha/URL is hash-pinned (verified against the
published artifact) but not built in CI.
- Make the seed chmod-644 test meaningful: pre-create dst at 0o600 so only the
explicit chmodSync can widen it (the prior assertion passed under the default
umask regardless of whether the chmod ran).
25/25 config-transform tests pass; arm64 + x64 Cursor artifacts verified.
* docs(devcontainer): rewrite code comments in plain English
The devcontainer comments had grown dense and jargon-heavy. Rewrite them
across all 9 files into short, plain-English sentences — same facts and
reasoning, just clearer wording.
Comments only; no code changed. Verified: the diff touches comment lines
only, 25/25 config-transform tests pass, devcontainer.json is still valid
JSONC with build.args + readonly mounts unchanged, shell scripts pass
`bash -n`, and prettier is clean.
* feat(devcontainer): persist AI CLI session state across container recreation
Add dedicated per-workspace named volumes (mount group 6) for the three
AI CLIs' session/resume state so `claude --resume`, `codex resume`, and
`cursor-agent resume` survive a rebuild, a full delete-and-recreate, and
the `docker volume rm <cli>-config-*` re-login fix:
- Claude -> ~/.claude/projects
- Codex -> ~/.codex/sessions
- Cursor -> ~/.cursor/chats + ~/.cursor/projects
The volumes are SEPARATE from the credential/config volumes and keyed
like the node_modules volumes (${localWorkspaceFolderBasename}-...-
${devcontainerId}), so wiping a config volume to force a re-login no
longer destroys session history. Session state already survived a plain
rebuild (it lived in the config volume); this closes the recreation,
volume-rm, and devcontainerId-change gaps.
Kept container-private (not host bind mounts) deliberately: transcripts
can contain pasted secrets, so a host bind would spill them to host
disk, widen the supply-chain write-through surface, and leak
cross-project transcripts. A commented-out opt-in host-bind block is
included for users who accept that trade-off.
post-create.sh: chown each new volume root explicitly (find -xdev stops
at the config-volume filesystem boundary and won't descend into them),
guarded with `[ -d ] || continue` so a missing root can't abort
provisioning under set -e.
README: document the topology, what survives vs not, the one-time
first-rebuild masking of pre-existing config-volume sessions, updated
rebuild/reset commands, and the trust-boundary impact.
* feat(devcontainer): isolate host AI-CLI config via seed-once copies + persist claude-mem
Replace the read-write host bind mounts for the AI-CLI shareable dirs
(Claude skills/agents/memory/commands/plugins; Codex plugins/prompts/
memories/skills; Cursor rules/commands/agents/skills/plugins) with a
seed-once copy from a read-only /host/.<cli> stage into the per-container
config volume. The container gets its own writable copy and can never
write back to the host, closing the write-through vector where a
compromised in-container dependency could drop a malicious agent, command,
skill, or plugin onto the host for the next host session to auto-load.
Add a per-container claude-mem named volume (claude-mem-${devcontainerId})
at /home/node/.claude-mem, seeded once from a read-only /host/.claude-mem
stage. claude-mem's multi-GB SQLite + Chroma store is kept off a host bind
(unreliable fcntl locking / corruption risk over 9p on Docker Desktop
Windows) while still surviving rebuilds.
- post-create.sh: seed shareable dirs (marker-gated, seed-once) and run
plugin-registry translation per seeded CLI; seed claude-mem behind a
completion-sentinel guard that self-heals an interrupted multi-GB copy;
chown the claude-mem volume only on first create.
- translate-plugin-registries.cjs: add selectRegistries() so translation
runs per-CLI seed-once instead of clobbering container-installed plugins.
- ensure-host-config-dirs.cjs: add ~/.claude-mem; drop the shareable
subdirs (no longer bind sources).
- devcontainer.json: drop the RW shareable binds; add the claude-mem
volume + read-only stage.
- README: rewrite trust-boundary, mount table, and rebuild/reset docs for
the copy model.
- tests: cover selectRegistries and the trimmed DIRS (30 pass).
* feat(devcontainer): add Bun 1.3.14, pinned via build arg
Installed by the official bun.sh/install script with the release tag
passed as the first positional arg, so the version is pinned even though
the install path itself is an unverified remote script (the one such
exception in the image — Cursor and the base image stay sha256/digest-
pinned). BUN_INSTALL is set in ENV so the binary lands at a known path
and the installer's rc-file edits don't matter. unzip is added to apt
since the Bun installer extracts a .zip.

* feat(devcontainer): persist gh auth via copy-into-volume model
Move ~/.config/gh from a read-only bind to the same read-only host
stage + per-container named volume pattern used for the AI CLI
credentials. post-create.sh seeds hosts.yml/config.yml from the
/host/.config/gh stage into the gh-config volume on create, so an
in-container `gh auth login` now persists across rebuilds while the
read-only stage still prevents any write-back to the host token.

* fix(devcontainer): bump Claude Code to 2.1.156 for Opus 4.8
The pin was 2.1.153, which predates Opus 4.8 support (added in
2.1.154). With DISABLE_AUTOUPDATER=1 the container never updated past
the pin, so Claude Code only offered models up to 4.7. Bump to the
latest 2.1.156 so Opus 4.8 is available.

* fix(ingestion): skip File->Member DEFINES edges for class members
Previously every symbol — including Methods and Properties that belong
to a class — received a direct File->Symbol DEFINES edge. This caused
the radial-layout view to show File linking directly to all Properties
and Methods, bypassing their enclosing class node and flattening the
OOP hierarchy.
Fix: gate the DEFINES emission on the symbol having no owner. Class
members are already reachable through the File->Class DEFINES edge and
the Class->Member HAS_METHOD / HAS_PROPERTY edges, so the redundant
direct edge is unnecessary and misleading in the graph.
The same guard is applied in all four emission sites:
- parsing-processor.ts (sequential fallback path)
- parse-worker.ts (main symbol loop + routed-property branch)
- call-processor.ts (routed-property branch)
Pipeline-graph golden updated: DEFINES 21→20, relationships 74→73.

so exported class methods and properties appear in wiki/cluster export

* fix(csharp): eliminate global-namespace typeBindings O(files²) OOM (#1871)
Large C# solutions with tens of thousands of files in the global
(unnamed) namespace OOM'd / hung for hours at "Resolving types
(Csharp 2/3)". PR #1905 fixed the BindingRef twin of this via the
`workspaceFqnBindings` fast-path, but left the typeBindings
propagation loop in `populateCsharpNamespaceSiblings` untouched: it
copies every global file's module-scope return-type bindings into
every OTHER global file's `Scope.typeBindings`. With S files in the
`''` bucket and K distinct method names, that is O(S²) time and
O(S·K) memory — ~1.3B Map entries (~65-130 GB) at 36k files.
Measured on a concentrated global-namespace fixture: the per-file
copy went quadratic (1000→2000 files = 3.06× for 2× the files,
65s at 2000). Route global-namespace module typeBindings through a
new scope-independent `workspaceTypeBindings` channel populated ONCE
(O(K)) and consulted as a fallback by the typeBindings chain-walkers
(`findReceiverTypeBinding`, `followChainPostFinalize`), instead of the
per-file copy. After: 2000 files 6.3s, 4000 files 6.8s, heap linear.
This also makes resolution MORE correct, not just faster. The C#
spec makes the unnamed namespace a single declaration space whose
members are "available for use in a named namespace", so global types
are visible from every file. The old per-file copy only exposed them
to OTHER no-namespace files; named-namespace files never saw them.
Consulting the shared channel from every scope chain mirrors how
Roslyn resolves against a single `Compilation.GlobalNamespace` symbol
rather than copying symbols per file.
Strengthen csharp-pipeline-benchmark.test.ts so it would catch this:
give each file a unique method name (a shared name collapses the
module-typeBinding key and skips all copies, hiding the blow-up) and
raise the concentrated scales to 2000 so the sub-quadratic assertion
trips on the regression.

* fix(csharp): generalize shared-channel resolution to concentrated named namespaces (#1871)
#1954 eliminated the namespace-siblings O(files²) OOM only for the global
('' / no-declared-namespace) bucket. A solution with all files under one
named namespace (e.g. file-scoped `namespace Company.Product;`, common in
modern .NET) still reproduced the #1871 blow-up — and in BOTH loops: the
BindingRef per-scope augmentation (#1905's twin) AND the typeBindings
per-file copy (#1954's twin) were each still O(N²) for a named bucket.
Generalize the shared-channel approach to named namespaces:
- Add namespace-keyed channels `namespaceFqnBindings` / `namespaceTypeBindings`
(the per-namespace analogues of `workspaceFqnBindings` / `workspaceTypeBindings`)
plus `accessibleNamespacesByScope`, populated ONCE per named bucket from the
existing `expandedNamespaces` derivation — O(defs), not O(files × defs).
- Make the shared walkers (`findReceiverTypeBinding`, `lookupBindingsAt`,
`followChainPostFinalize`) namespace-aware: after the per-scope chain and the
flat global channel miss, consult the per-namespace channels gated by the
caller module's accessible namespaces. Language-neutral — only the C# hook
populates the channels; the machinery names no language (AGENTS rule).
- Precedence preserved: local chain → named namespace → global. Named is
consulted before the flat global channel because pre-#1871 named siblings
lived in the chain / bindingAugmentations (above the workspace channel), so a
name in both a named and the global namespace must still resolve named-first.
- `using static` member exposure and the global '' fast-paths are unchanged.
Parity-neutral: `run-parity.ts --language csharp` passes (legacy DAG ==
registry-primary, 218 tests each); the C# resolver suite (386 tests) is green.
Measured: a concentrated named namespace at 500/1000/2000 files now scales
linearly (~0.57×) and ~5.6s at 2000 files, vs the quadratic blow-up before.
Tests:
- New always-run unit coverage for the walker fallbacks
(namespace-channel-lookup.test.ts): global `workspaceTypeBindings` (the #1954
channel previously covered only by a gated benchmark), namespace gating /
no-leak, named-before-global precedence, local shadowing, loop termination.
- Extend the immutability validator + invariant I8 to the new channels and
`workspaceTypeBindings`; update the `mkIndexes` factory.
- Add a concentrated-NAMED-namespace shape to the C# pipeline benchmark with
the sub-quadratic scaling assertion and an edge-count sanity check.

* feat(swift): migrate Swift to scope-based registry resolution (#937)
Ring 3 of RFC #909 — Swift is the final language migrated to the
scope-based registry resolution pipeline. Flips Swift into
MIGRATED_LANGUAGES so registry-primary call resolution is the production
default, with dual-mode parity proven: the resolver suite passes 77/77
under both the legacy DAG (REGISTRY_PRIMARY_SWIFT=0) and the
registry-primary path (REGISTRY_PRIMARY_SWIFT=1).
New language module src/core/ingestion/languages/swift/ (mirrors csharp/):
query, captures, interpret, import-decomposer, receiver-binding,
signature-bindings, arity (+metadata), merge-bindings, simple-hooks,
import-target, target-siblings, implicit-imports, sibling-type-bindings,
scope-resolver, cache-stats, index. Parse-time hooks wired into the
existing flat languages/swift.ts (coexists with the swift/ dir, like
kotlin) and the resolver registered in the scope-resolution registry.
tree-sitter-swift 0.7.1 specifics handled in the Swift module (not in
shared code):
- class / struct / extension all parse to class_declaration; extensions
are re-keyed onto the extended type so members hoist (like C# partial).
- if-let / guard-let have no if_let_binding node — the optional binding
is synthesized from if_statement / guard_statement.
- the name: field is reused for func name, param labels, param types and
return type, so param/return type-bindings are synthesized in code
(signature-bindings.ts) rather than via a multi-name query.
- no `new` keyword: Type(...) and Type.init(...) are synthesized into
constructor type-bindings.
Shared-pipeline additions are language-agnostic (AGENTS.md: no language
names in shared ingestion code):
- constructorCallTargetsClass on the ScopeResolver contract +
free-call-fallback option + run.ts wiring: when true, Type(...) links
to the Class def rather than its explicit init Constructor.
- pickUniqueGlobalClass: constructor-branch global fallback for
cross-file types absent from the call site's lexical bindings, deduped
by qualifiedName so extension/partial fragments aren't seen as
ambiguous.
- emitImplicitImportEdges: same-module File->File IMPORTS edges (Swift
whole-module visibility has no syntactic import to drive the generic
ImportEdge pipeline).
Import resolution: rewrote the O(n^2) module scan in
import-resolvers/configs/swift.ts with a WeakMap-memoized index.
Benchmarks & guards:
- Swift added to bench/scope-capture/measure.mjs + baselines.json
(fingerprint + 1.5x scaling budget); `--check` passes for all 7
languages, Swift scaling 0.98 (linear).
- golden capture-parity test
(test/unit/scope-resolution/swift/swift-captures-golden.test.ts +
fixtures/swift-captures-golden/) mirrors the csharp golden.
- O(n) scope-capture tripwire
(test/integration/swift-scope-capture-tripwire.test.ts).
Full Swift test glob: 3 files / 88 tests pass; tsc --noEmit clean; no
cross-language resolver regressions.

* fix(typescript): fix HOC pattern false positives and add export default HOC support
Fixes two related issues from #1876:
1. False positives: `const x = arr.map(a => ...)` was incorrectly classified
as a Function node. Split HOC patterns into identifier vs member_expression
variants and apply a #not-any-of? blocklist for 36 array methods
(map, filter, reduce, forEach, etc.) across all four query files.
Runtime safety-net in tsExtractFunctionName uses a module-level ARRAY_METHODS
constant (avoids per-call Set re-allocation).
2. Missing support: `export default defineEventHandler(async (e) => { ... })`
and similar HOC-wrapped default exports were invisible. Added 4
export_statement patterns (TS + JS, legacy + registry-primary) and extended
tsExtractFunctionName to derive the function name from the callee identifier.
Now correctly distinguishes:
- `const data = arr.map(account => ({...}))` → Const only (was Function+Const)
- `const Button = forwardRef(...)` → Function:Button (unchanged)
- `const Card = React.memo(...)` → Function:memo (unchanged)
- `export default defineEventHandler(...)` → Function:defineEventHandler (new)
Tests: add 2 fixture files and 4 test cases to typescript-hoc-wrapped suite
covering the export default HOC positive case and array method exclusion
negative case.

* fix(workers): fail fast instead of silently degrading on worker-pool startup failure (#1741)
When an explicitly-sized worker pool (--workers <N>) fails to start because
every worker crashes during top-of-script init, the parse phase used to log a
swallowed `logger.warn` and silently fall back to the ~10x slower sequential
parser. In #1741 (rc99) that turned a worker-startup regression into a
123-minute "stuck" parse with no explanation.
This change:
- Surfaces the real crash: the pool now spawns workers with `{ stderr: true }`,
tees + captures each worker's stderr, and attaches the tail to its
readiness-failure messages (propagated via
WorkerPoolInitializationError.readinessFailures). "did not report ready"
now carries the underlying native-binding/import error.
- Gates the fallback: when --workers was explicit and fallback was not opted
into, a total startup failure throws an actionable error instead of
degrading. Auto-sized pools still fall back, but loudly (logger.error +
progress warning). New --allow-sequential-fallback flag (+ i18n) opts back in.
- Adds env-gated worker bootstrap-stage logging (GITNEXUS_WORKER_BOOTSTRAP /
--verbose): imports+grammars loaded -> ready sent -> first task received, so
a slow/crashing startup is diagnosable.
Tests: all-workers-failed gating (fatal vs loud degrade), stderr surfacing,
and the updated lazy-cache fallback contract (opt-in flag + fail-fast).

* feat(ingestion): always-on slow-file watchdog for deferred call resolution (#1741)
The original #1741 symptom is a run that appears stuck at "Resolving calls
(all chunks)... (9000/18066 files)" — the progress bar freezes inside a single
file's call resolution and nothing reaches the log. Rich per-file deferred
diagnostics already exist, but only behind --verbose / GITNEXUS_PROFILE_DEFERRED,
so a plain `analyze` run gives the user a frozen bar and silence.
Add an always-on (not verbose-gated) per-file watchdog in
processCallsFromExtracted: when a single file's call resolution exceeds
alwaysOnSlowFileWarnMs() (default 15s, override GITNEXUS_SLOW_FILE_WARN_MS,
0 disables) it emits a throttled logger.warn naming the culprit file and the
files-resolved-so-far — turning the silent stall into one actionable line.
Throttled (>=30s between warnings) so a genuinely slow repo can't storm the log.
The watchdog is observation-only; resolution behavior is unchanged.
Note: deliberately did NOT add a heritage child x parent product cap — the name
lookups are O(1) (type-registry Map.get) and the product is bounded, so the
heritage build is not the bottleneck; a cap would risk dropping real edges for
no measured gain.

* test(ingestion): worker-vs-sequential parity guard for binding/edge collapse (#1741)
rc99 produced almost no bindings/edges (13 bindings vs rc91's 106,305) because
a worker-path failure left extracted results unmerged while the run still
reported success. Rather than an arbitrary "implausibly low" runtime threshold
(which false-positives on legitimately low-binding repos/languages), pin the
invariant directly: for the same repo, worker mode and sequential mode must
produce the same graph.
The test runs the ts-simple cross-file fixture through worker mode
(workerPoolSize + lowered threshold) and sequential mode (skipWorkers), and
asserts: usedWorkerPool is true/false respectively (guards the test itself
against a silent fallback masking divergence), identical CALLS/IMPORTS/DEFINES/
HAS_METHOD edge sets and Class/Function/Method defs, and non-zero CALLS/IMPORTS
(the rc99 collapse signature).

* fix(workers): arm fail-fast for env-sized pools + fix watchdog /0 denominator (#1741)
Addresses two review findings on the #1741 worker-startup PR:
- Fail-fast gate missed the env channel. `explicitWorkers` keyed only off
the `--workers` flag, so a pool sized via `GITNEXUS_WORKER_POOL_SIZE`
(with no `--workers`) silently degraded to sequential on a total
worker-startup crash — reproducing the original #1741 symptom for
env-channel operators. The gate now arms on a non-zero size from either
channel, via a single-source `envWorkerPoolSize()` helper exported from
worker-pool.ts (also rewired through resolveAutoPoolSize). The fatal
message now names the channel actually used instead of "--workers undefined".
- Always-on slow-file watchdog printed "Resolved N/0 files". `resolvedTotal`
was pre-counted only on the profile path, but the watchdog reads it on
every run, so a plain `analyze` showed a bogus /0 denominator on exactly
the unprofiled hang the watchdog exists to explain. Pre-count now runs
whenever its result is read (profile path OR watchdog active).
Tests: strengthened the watchdog test to assert "1/1" (not "/0"); added
env-channel fail-fast/degrade cases and made the gating suite hermetic
against an ambient GITNEXUS_WORKER_POOL_SIZE.

* feat(workers): self-healing worker pool replaces the fail-fast flag (#1741)
Replaces the interim --allow-sequential-fallback flag with automatic,
bounded self-healing in the worker pool — industry-standard supervision
(OTP restart-intensity, systemd StartLimit, circuit-breaker, AWS jittered
backoff) translated to the Node worker_threads pool.
worker-pool.ts — bounded startup self-heal (the missing layer):
- A worker that crashes during top-of-script init is now RETRIED with
capped, full-jitter backoff (BASE 250ms, CAP 2s) up to a small per-slot
budget, so a transient blip heals itself with no operator action. The
prior code dropped an unready initial slot on its first crash.
- A DETERMINISTIC crash-loop (>=2 fresh workers crash with the same
normalized signature before any reaches ready — the #1741 missing
native-binding case) is detected and short-circuited, so the pool gives
up in ~1s instead of burning every slot's budget. Correctness rests on
the STRUCTURAL signal (zero workers ever ready + budget exhausted), so a
missed signature only costs a few seconds, never a misfire; even a
stderr-less crash groups via its normalized "exited with code N" message.
- Backoff sleeps are cancellable (unref'd timer + abort on terminate), so
terminate() can't be wedged for the backoff duration.
- WorkerPoolInitializationError now carries a crashClass for an accurate,
flag-free message. The runtime respawn/breaker path is unchanged.
parse-impl.ts — collapse to automatic fail-fast:
- handleWorkerStartupFailure always logs the real cause then THROWS with
the captured crash + `--workers 0` as the explicit sequential escape.
No more degrade branch; no dependence on how the pool was sized. This is
reached only after the bounded self-heal is exhausted, so it can't
resurrect the #1741 silent 123-minute sequential grind. Construction
failure (broken install) also fails fast instead of degrading silently.
Removed --allow-sequential-fallback end to end (CLI, run-analyze, pipeline,
i18n). --workers 0 remains the explicit "parse sequentially" path; one flag
removed, none added. Grounded in a research+critique pass; the critique's
hazards (N-parallel race, empty-stderr timing, non-cancellable sleep,
runtime-breaker regression) are addressed or scoped out by design.
Tests: startup self-heal (transient recovers; deterministic fails fast
without burning the budget); gating test rewritten to the fail-fast-always
contract; obsolete degrade test removed.

* fix(workers): ref + cancel startup backoff so transient retries aren't dropped (#1741 U1)
abortableSleep unref'd its backoff timer, so a transient startup retry could be
silently dropped if that timer was the last ref'd handle on the event loop —
the process could exit mid-recovery. Keep the timer ref'd (a pending retry is
necessary work) and register a cancel fn in a pool-scoped set; terminate() now
clears pending backoffs so it can't be wedged for the backoff cap. A normally
fired timer self-deregisters (clear-on-settle), so no timer lingers after a
slot's retry loop exits. Exposes pendingStartupTimers in getStats.
Tests: terminate-during-backoff cancels + spawns nothing after (R2); the
recovery test now asserts no startup timer lingers after settle (R1).

* fix(workers): route GITNEXUS_WORKER_POOL_SIZE=0 to sequential, not a phantom fail-fast (#1741 U2)
env=0 (no --workers) built a size-0 pool that threw a fabricated "retry budget
exhausted / native binding" crash. The shouldUseWorkers gate now routes env=0
to the sequential path before pool construction — but only when no explicit
--workers <N> was given, so an explicit positive size wins over an ambient
env=0. The route emits one log line so the undocumented (possibly accidental)
env=0 case is observable instead of a silent degrade.
envWorkerPoolSize is un-exported (module-internal sizing reader); a new
workerPoolDisabledByEnv() predicate serves the gate. Empty/whitespace env is
now treated as unset (auto formula), not 0 — an empty assignment is an accident,
not a request for zero workers. Reattached the detached resolveAutoPoolSize
JSDoc and corrected the stale docstring.
Tests: env=0 → sequential (no spawn); explicit --workers wins over env=0;
workerPoolDisabledByEnv unit (0=true, positive/empty/invalid=false); getStats
shape updated for pendingStartupTimers.

* fix(workers): make deterministic crash-loop detection conservative (#1741 U3)
The old tally counted crash EVENTS in a shared signature->count map, so a
simultaneous transient crash storm (e.g. spawn EAGAIN under fork pressure) or
a single slot crashing identically twice falsely tripped "deterministic" and
hard-aborted work that would have self-healed. Replace it: a crash counts
toward deterministic only after its signature REPRODUCES across a respawn on
the same slot, and the short-circuit fires once >=2 distinct slots reproduced
(or 1 for a size-1 pool). Every slot now gets >=1 self-heal attempt before any
short-circuit; the structural budget floor still bounds the worst case.
crashSignature now also collapses Windows backslash paths and bare (no-0x) hex
runs so the fast-path fires on those platforms; exported for unit testing.
Tests: simultaneous storm self-heals (the discriminator vs an attempt-0 rule);
distinct-per-attempt crashes classify transient-exhausted; single-slot
reproduction classifies deterministic; crashSignature normalization unit.

* fix(workers): class-aware startup failure hint + reattach detached JSDoc (#1741 U4)
The "often a missing/broken native binding" hint was appended to every
failure class, including a pool *construction* failure where no worker ever
ran (a missing build / bad worker path). Make the hint class-aware: keep it
for the readiness/init classes, use a construction-specific hint otherwise,
and surface the construction error (e.g. "Worker script not found: …")
verbatim. Reattach the waitForWorkerReady JSDoc that the stderr-capture block
had detached from its function. (The abortableSleep docstring was already
corrected in U1.)
Tests: construction message surfaces the real error + drops the native-binding
guess; deterministic/transient messages keep the hint (regression guard).

* feat(ingestion): tree-sitter node-type/field validation gate + remove dead literals
Add a CI gate (test/integration/grammar-literal-validation.test.ts) validating
every node-type and field-name literal in the ingestion code layer against each
grammar's node-types.json, with a live `new Parser.Query` probe fallback for
literals the static JSON under-reports. Covers all three surfaces:
- legacy Call-Resolution DAG (type-extractors, *-extractors/configs) + the
ungated structure phase (field/method extractors, export-detection) — AST scan;
- registry scope-resolution captures + scope queries (Mode 3 compile);
- the registry RESOLUTION layer (scope-resolver/type-binding/receiver-binding/
interpret/arity/import-decomposer …) via a TS-TypeChecker discriminator that
collects a literal ONLY when its `.type` receiver is a tree-sitter SyntaxNode
(so resolved-symbol `.type` kinds like 'Class' are never mistaken for nodes).
Helpers: test/helpers/{grammar-introspection,literal-collectors}.ts.
Remove every existence-dead literal the gate surfaces (behavior-neutral
dead-branch/fallback deletions verified absent from the installed grammar),
spanning the legacy, structure-phase, and registry production paths:
reference_type/pointer_type/scoped_identifier/scoped_type_identifier/
rvalue_reference_declarator/variadic_parameter (C/C++), equals_value_clause/
identifier_name/simple_identifier/record_struct_declaration/record_class_declaration
(C#), generic_type/`type` field (Dart), nullable_type (PHP), method_call/symbol
(Ruby), method_call_expression/slice_type/shorthand_field_pattern (Rust),
struct_declaration/internal_name (Swift), comment (Java), parameter/
parameterized_type and dead childForFieldName('pattern'|'modifiers'|
'formal_parameters'|'declaration'|'default'|'return_value'|'alias_clause') /
class_expression fallbacks. Gate ships with an empty allowlist.
One behavior FIX (scope-resolution): PHP `findEnclosingTypeDeclaration` omitted
`anonymous_class`, so a method inside an anonymous class mis-bound `$this` to the
enclosing named class; add `anonymous_class` so it is correctly skipped.
Verified: tsc clean; gate green (empty allowlist); scope-resolution parity 26/26
on both REGISTRY_PRIMARY_*=0 and =1; resolver suite no new failures.

* test(ingestion): assert real grammar node types in #1920 dead-literal tests
Three tests asserted defensive handling of node types the installed
grammars never emit (verified via real tree-sitter parse), so they broke
once the dead literals were removed in af9d709f:
- parsing.test.ts isNodeExported / csharp: `record struct` and `record
class` both parse to `record_declaration` (kept in CSHARP_DECL_TYPES) —
tree-sitter-c-sharp emits no `record_struct_declaration` /
`record_class_declaration` node. Switch the two mock nodes to
`record_declaration`.
- extract-generic-type-args.test.ts: Java emits `generic_type` and Kotlin
`user_type`+`type_projection`; `parameterized_type` is produced by no
installed grammar, so the shared extractor returns [] for it. Convert the
case to a documented negative assertion (real paths already covered by the
generic_type cases).
No source behavior change: production export detection (record_declaration)
and generic type-arg extraction (generic_type / type_projection) were
already correct. Fixes the 3 CI failures on PR #1937.
Issue #1920 (epic #1919).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(ingestion): keep parameterized_type generic-arg extraction (allowlisted)
Restore the `parameterized_type` branch in extractSimpleTypeName /
extractGenericTypeArgs (type-extractors/shared.ts) so a parameterized_type
node still yields its type arguments (List<User> -> [User]). Current
tree-sitter-java emits `generic_type` and tree-sitter-kotlin
`user_type`+`type_projection`, so this is a defensive alternate node kept
for grammar-version resilience; it is allowlisted in the node-type
validation gate with a documented justification rather than removed.
extract-generic-type-args.test.ts now asserts the User type argument is
captured from a parameterized_type node.
Issue #1920 (epic #1919).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(ingestion): extract generic args from real grammar nodes, drop parameterized_type guess
extractGenericTypeArgs / extractSimpleTypeName special-cased `parameterized_type`,
a node type NO installed grammar emits (real parse: Java/TypeScript/Rust ->
generic_type, C# -> generic_name, Kotlin -> user_type). It was a guess masking a
real gap; remove it.
The genuine 'Kotlin alternate node type' is `user_type` (`List<User>` parses to
user_type > [type_identifier, type_arguments]), which the extractor returned []
for. Handle it: read a user_type's own type_arguments, else recurse into its
wrapped child (preserving the existing user_type > generic_type unwrap). No
production caller passes user_type today (Kotlin generics resolve via jvm.ts), so
this only makes the function's documented Kotlin contract correct — zero
behaviour change for current callers (Java/TS/C#/Rust pass generic_type/name).
Replace the mock parameterized_type test with REAL-PARSE coverage across
Java/TypeScript/C#/Rust/Kotlin (+ Java Map<String,User>) so a wrong node-type
guess can't silently pass again. Gate allowlist returns to empty.

* style(test): wrap real-parse cases to prettier printWidth (CI format gate)
CI runs `prettier --check .` from the repo root (printWidth 100) and flagged the
new real-parse cases array's long single-line object literals. Wrap them.
Format-only; no behaviour change.

* test(ingestion): node-scoped field probe oracle for the literal gate (U1)
Add probeField(language, nodeType, field) — the node-scoped analogue of
probeNodeType: compiles `(<nodeType> <field>: (_)) @_` against the live
grammar and classifies TSQueryErrorStructure/Field -> dead, TSQueryErrorNodeType
(node absent here) -> unavailable, compile -> valid. Conservative-toward-valid
(supertype-typed fields make some wrong fields compile), so it never produces a
false positive. Add isFieldError classifier; make validateField's node-scoped
path membership-then-probe so node-types.json field under-reporting can't yield
a false `dead`.
Foundation for the node-scoped field validation gate (no gate behavior change
yet). Issue #1920 (epic #1919).
* test(ingestion): capture receiver node type + extend Mode-4 to type-env.ts (U2)
CollectedField gains receiverNodeType, captured conservatively by
receiverNodeTypeOf: only when a childForFieldName receiver is unambiguously
narrowed by a single enclosing positive guard (if (recv.type==='X') then-branch,
or switch case 'X') with no reassignment/shadowing of the receiver in the
enclosing function. Any uncertainty -> undefined (sound global fallback);
fail-safe (benign false negative, never a false positive).
Extend Mode-4's resolutionLayerFiles to include shared resolution files directly
under ingestion/ (type-env.ts), tagged with the full gated language set via
fileLanguages (valid-if-any). Entries now carry a language SET. Rename
Mode2Result -> ScanResult; fix the header doc (THREE -> FOUR modes).
Gate behavior unchanged until U3 consumes receiverNodeType. Issue #1920.
* feat(ingestion): node-scoped field gate + remove gate-flagged dead literals (U3, U4)
U3: the gate validates childForFieldName lookups node-scoped (validateField with
the captured receiverNodeType) and fails loudly on a degraded/vacuous run
(asserts resolutionLayerProgramOk, floors collected counts, requires
knownFailures empty).
U4: remove every dead field/literal the hardened gate flags — all behavior-neutral
(the dead disjunct never fired on reachable nodes; verified by real parse + the
type-extractor/resolution unit suites, 484 passing):
- type-env.ts: parameterized_type (emitted by no grammar) and switch_block_label
(real Java enhanced switch is switch_label/switch_rule) from the SyntaxNode .type sets
- languages/csharp/captures.ts: generic_name has no `name` field -> firstNamedChild
- type-extractors/jvm.ts: Kotlin property_declaration has no name/type fields
(positional children) -> findChild; drop the else-branch `pattern` fallbacks x2
- type-extractors/csharp.ts: drop the else-branch `pattern` fallback (parity with go/php/python/swift)
Gate green with node-scoped validation on; tsc clean. Closes the Mode-4
type-env coverage opened in U2. Latent follow-up: Java enhanced-switch arms
(switch_rule) are absent from NARROWING_BRANCH_TYPES — a separate behavior fix.
Issue #1920 (epic #1919).
* fix(java): exclude interleaved comments from call arity (U5)
tree-sitter-java emits block_comment/line_comment as named children of
argument_list; counting them inflated @reference.arity / @reference.parameter-
types / @reference.arg-names for any Java call with an inline comment, which
skews arity-based overload resolution (arity feeds call-processor symbol-ID
generation). Filter them at the single arg-list site (also corrects the
downstream args.map). The previously-removed `comment` literal never matched —
the real nodes are block_comment/line_comment (the #1920 gate lesson).
Isolated from the behavior-neutral gate units (U1-U4) since this changes
production graph output. Java resolver suite 178/178; new java-call-arity test
covers block/line comments, leading comment, constructor calls, and the
no-comment regression. Issue #1920 (epic #1919).
* test(ingestion): cover Kotlin/C# multi-arg generics + tighten probe assertions (U6)
- extract-generic-type-args: add real-parse Kotlin Map<String,User>
(user_type > type_arguments > type_projection) and C# Dictionary<string,User>
(generic_name > type_argument_list) multi-arg cases.
- grammar-introspection: the probeNodeType test now asserts 'dead' for a bogus
node on installed grammars (not merely not-throw), and documents the null-model
split (validateField -> unavailable; validateNodeType -> still probes the live
grammar). Issue #1920 (epic #1919).
* style(test): apply root prettier formatting (CI format gate)
CI runs `prettier --check .` from the repo root (printWidth 100); the gitnexus/
pre-commit hook formatted these two files differently. Format-only, no behavior
change. Issue #1920.

* bench(python-scope): build-free measure harness + baseline fingerprint for emitPythonScopeCaptures
ce-optimize scaffolding for the python-scope-capture run. Mirrors the Go
scope-capture harness (#1848): imports the .ts hotpath via tsx, times
emitPythonScopeCaptures on a synthetic DAO source at 250/800 entities, and
pins an order-independent sha256 capture fingerprint over the whole
lang-resolution/python-* corpus + a fixed 20-entity DAO as the correctness gate.
Baseline (current code) is O(n^2): 250->800 entities (3.2x) -> 10.7x time
(1062->11343ms), scaling_ratio 3.34.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* optimize(python-scope-capture): thread captured nodes to kill O(n^2) findNodeAtRange re-walks
emitPythonScopeCaptures re-derived each tree-sitter match's AST node via
findNodeAtRange(tree.rootNode, ...) on every match, scanning all of root's named
children per call -> O(matches x rootChildren) ~ O(n^2). The same #1848 bug Go
had (fixed in eaf0a305), mirrored in Python's captures.ts.
Thread the query-captured SyntaxNode (c.node) through a parallel tag->node map
and use it directly for all three sites (import / @scope.function /
@declaration.function). The Python scope query captures the full
statement/definition node, so the captured node IS the one the old code
re-derived by range — no ancestor walk needed (simpler than Go's import case).
Output is byte-identical: an order-independent sha256 capture fingerprint over
all 188 lang-resolution/python-* fixtures + a 20-entity DAO is unchanged.
800 entities: 11343ms -> 319ms (35.5x); 250: 1063ms -> 95ms (11.2x);
scaling_ratio 3.34 -> 1.05 (quadratic -> linear). tsc clean; 291 python
scope-resolution + resolver tests pass.
Adds a golden capture-parity test (forward-drift guard across the python-*
corpus + DAO shape) and a non-gated O(n^2) regression tripwire (400-entity
source, 346ms vs a 10s budget).

* optimize(python-scope-capture): index Python import resolution to kill O(imports x files) scans
resolvePythonImportTarget's fallback path scanned the entire repo file set on
every unresolved/external dotted import — once in hasRepoCandidate (package gate)
and once in resolveAbsoluteFromFiles (suffix match) — giving O(imports x files)
~ O(n^2) in the resolution phase (audit follow-up to the capture-phase #1848
mirror).
Add a per-file-set index (byBasename buckets + .py dir-prefix set + normalized
path set), memoized on the allFilePaths Set via a WeakMap so it is built once per
run and reused across every import. The two O(files) scans become O(1)/O(bucket)
lookups. The shared buildSuffixIndex is deliberately NOT reused: it keeps only a
single path per suffix (longest wins) and cannot reproduce Python's exact
fewest-segments-then-lexicographic tie-break across all candidates (see the
import-target.ts:72 rationale) — so a purpose-built index is used instead.
Output is identical: a resolver-output fingerprint over 10,021 cases (exhaustive
branch matrix — tie-breaks, gating, collisions, windows paths — plus a 400-repo
deterministic fuzz) is byte-for-byte unchanged
(e6ec1a59...). Worst-case scaling (k imports x k files): 500/1000/2000/4000 went
25/62/231/899ms -> 1.2/2.9/6.7/10.7ms (84x at 4000, quadratic -> linear).
tsc clean; 303 python scope-resolution + resolver tests pass; adds a 10-case
parity guard pinning the tie-break / gating / collision semantics the index
must preserve.

* fix(python): land the import-index reuse on the registry-primary path (PR #1918 P1)
The PythonFileIndex WeakMap is keyed on allFilePaths Set identity, but
pythonScopeResolver.resolveImportTarget wrapped the orchestrator's stable
run-level set in `new Set(allFilePaths)` per import, handing a fresh key to
every import — so the index rebuilt on every import and the O(imports x files)
cost this index removed persisted on the production path (PR #1918 review P1).
Thread ReadonlySet<string> through the resolver chain (PythonResolveContext,
getPythonFileIndex, the WeakMap key, resolveAbsoluteFromFiles, hasRepoCandidate,
resolvePythonImportInternal, tryResolveWithExtensions — all read-only) and drop
the per-import copy so the stable set reaches the WeakMap key. Mirrors the C#
counterpart (csharp/import-target.ts), which already keys on ReadonlySet.
Guard it deterministically: an ungated index-build counter (index-stats.ts) +
a production-path integration test that drives pythonScopeResolver over 300
imports on a stable set and asserts the index is built ONCE (was 300 pre-fix).
tsc clean; resolver-output fingerprint unchanged (e6ec1a59); 369 python
scope-resolution + resolver tests pass.

* perf(python): index only .py files in the import-resolution index (PR #1918 P3b)
getPythonFileIndex pushed every workspace file into byBasename (and normSet),
but Python import resolution only ever queries .py paths — module <seg>.py,
package <seg>/__init__.py, and .py directory prefixes. Non-.py files (.ts, .go,
…) could never match any lookup, so they were pure dead weight in the index on
polyglot monorepos.
Skip non-.py files at the top of the index builder. dirPrefixes was already
.py-gated; this extends the same guard to byBasename and normSet (both also
.py-only consumers), so it is behavior-preserving. Resolver fingerprint
unchanged (e6ec1a59); adds a polyglot parity case proving .ts/.go siblings
never affect resolution.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* perf(python): parent-key the __init__ bucket to kill package-count skew (PR #1918 P2b)
The suffix fallback's package form looked up byBasename.get('__init__.py'),
which holds every __init__.py in the repo — so every multi-segment package
import (pkg.sub) iterated all N packages to find the one ending /sub/__init__.py.
Add byInitParent: __init__.py files keyed by their last two components
(<parentDir>/__init__.py). The package lookup now targets only same-named
package dirs (typically O(1)) and confirms the full suffix, so the final
candidate set and tie-break are unchanged. __init__.py files stay in byBasename
too, so the rarer explicit "pkg.__init__" import still resolves via the module
(<lastSeg>.py) lookup.
Resolver fingerprint unchanged (e6ec1a59); adds parity cases for a nested
package (same-parent noise filtered by the suffix confirm) and an explicit
pkg.__init__ import.

* fix(python): reproduce old startsWith gating for absolute paths + re-baseline (PR #1918 P3a)
getPythonFileIndex built dirPrefixes by split('/')+filter(Boolean), which drops
the leading empty component of an absolute path: "/repo/svc/x.py" yielded
{repo/, repo/svc/}. The old full-scan gate compared the whole normalized path,
where "/repo/svc/x.py".startsWith("repo/svc/") is false — so the index gate
PASSED where the old gate BLOCKED, an absolute-path-only divergence (production
paths are repo-relative, so this never fired in production).
Build dirPrefixes from every slash-terminated prefix of the full path instead
(including the leading "/" for absolute paths), so dirPrefixes.has(X) matches
exactly when the old f.startsWith(X) did. For repo-relative paths the prefix set
is identical, so production behavior is unchanged.
This is NOT cosmetic. Extending the fingerprint harness with absolute-path file
sets surfaced 12 fuzz cases (out of ~4000 new absolute cases) where the pre-fix
index resolved an import the old code left unresolved — e.g. `pkg.thing` over
{/repo/pkg/__init__.py, /repo/vendor/pkg/thing.py} from /repo/app/main.py
resolved to /repo/vendor/pkg/thing.py under the buggy gate but is null (old and
fixed). The fix removes those absolute-path false positives.
Re-baseline justification: the committed resolver fingerprint moves
e6ec1a59 -> d51ea9ed because the harness now adds ~4000 absolute-path cases
(branch matrix incl. the reviewer's exact case + a 200-repo absolute fuzz). The
relative-path subset is unchanged: the original 10,021-case relative corpus
still hashes to e6ec1a59 after the dirPrefixes fix (the fix only alters
absolute-path prefixes). The new baseline encodes the old-startsWith-equivalent
(correct) behavior, verified by diffing the fixed vs. pre-fix harness output.
Adds parity cases pinning the absolute false-positive (now null) and a
repo-relative control of the same shape (still resolves). tsc clean.

* test(python-bench): add --check mode + REPS=7 to the scope-capture harnesses (PR #1918 P2a)
The bench harnesses were dev-only — nothing compared the committed fingerprints
or guarded the scaling, so an O(n^2) regression (or a P1-style cache miss) could
land silently.
Add a --check mode to both:
- measure.mjs: assert the capture fingerprint == baseline-fingerprint.txt AND
scaling_ratio < 1.5 (linear), exit non-zero on either. REPS bumped 3 -> 7 to
stabilize the median on shared CI runners.
- import-target-fingerprint.mjs: assert the resolver fingerprint ==
baseline-import-target-fingerprint.txt, exit non-zero on drift.
Without --check both still print JSON for dev use / deliberate re-baselining.
Verified: --check passes on the current tree (capture f2b4376f / scaling 1.04;
resolver d51ea9ed) and exits 1 with a clear message on a corrupted baseline.
Wired into CI by the dedicated benchmark job (next commit).

* ci(bench): add a dedicated benchmark job wiring in the gated cross-language suites
The cobol/csharp/rust/php/ruby *-pipeline-benchmark.test.ts suites are gated
behind GITNEXUS_BENCH, so the main coverage job skips them — their O(n^2)
scaling guards never actually ran in CI. Add a dedicated "benchmarks" job to the
Tests reusable workflow that runs them with GITNEXUS_BENCH=1, plus the Python
scope-capture and import-resolution fingerprint + scaling guards
(measure.mjs --check, import-target-fingerprint.mjs --check) from PR #1918.
Runs with --no-file-parallelism: the suites measure wall-clock and peak heap, so
parallel forks both skew the timings and OOM the worker pool (reproduced locally:
the parallel run crashes a worker; serial passes 5/5 in ~80s). The job is part of
the Tests workflow, so it gates the existing CI Gate required check.

* ci(bench): exclude go-pipeline-benchmark from the gated job (fork-pool instability)
Validation surfaced that go-pipeline-benchmark.test.ts's worker-pool (#1848)
suite spins a real worker pool that exits unexpectedly under vitest's fork pool,
crashing the run (1 of 3 tests, repeated). Including it would make the new
benchmark gate flaky. The other five language pipeline benchmarks
(cobol/csharp/rust/php/ruby) run clean serially (5/5, ~84s). Go is already
guarded by its non-gated O(n^2) tripwire (main coverage job) + golden parity
test, so coverage is preserved. Documented inline.

* ci(security): set persist-credentials false on all ci-tests checkouts (zizmor artipacked)
The new benchmarks job (and the pre-existing tests / cross-platform jobs) used
actions/checkout with the default persist-credentials, leaving the token in
.git/config. The tests job uploads a test-reports artifact, so that is the
literal credential-persistence-through-artifacts case zizmor's artipacked audit
flags; the others persist creds needlessly.
None of these jobs push — they run npm + vitest only — so persist-credentials:
false is safe (the packaged-install-smoke job already runs setup-gitnexus this
way). All four ci-tests.yml checkouts are now consistent.

* bench(scope-capture): unified build-free measure harness for all benchmarked languages
Adds a single tsx harness that measures emit<Lang>ScopeCaptures for every
language with a pipeline benchmark (go, csharp, rust, php, ruby, cobol):
per-language synthetic-DAO scaling (250/800 entities) + an order-independent
sha256 fingerprint over each <lang>-* fixture corpus, with a --check mode gating
both against baselines.json.
It immediately surfaced that csharp, rust, php and ruby still carry the
O(matches x rootChildren) findNodeAtRange(tree.rootNode,...) root-walk that was
fixed for go (#1915) and python (#1918): scaling ratios 3.13 / 3.31 / 3.04 /
3.07 (vs ~1.0 for the fixed go and cobol). They are flagged known_quadratic in
baselines.json so CI guards drift + worsening until each gets the threaded-node
fix (following commits).

* perf(ruby): linearize scope-capture (thread captured nodes + dedup set)
emitRubyScopeCaptures re-derived each match's node via findNodeAtRange(tree.
rootNode,...) per match (import / scope.function / declaration.function /
heritage / attr / call-arity), and the constructor-return pass ran out.some(...)
once per method over the growing output array — two O(n^2) shapes (measured
scaling 3.07).
Thread the query's captured node (c.node) through a nodeMap and resolve each
anchor with a type-guarded lookup (nodeIfType), and precompute the YARD-return
dedup keys into a Set. Output byte-identical (capture fingerprint over the
ruby-* fixture corpus + DAO unchanged); scaling 3.07 -> 1.11 (linear). 127 ruby
resolver tests pass; tsc clean.

* perf(php): linearize scope-capture (thread captured nodes)
emitPhpScopeCaptures re-derived each match's node via findNodeAtRange(tree.
rootNode,...) per match (import / scope.function / declaration / call-arity),
giving O(matches x rootChildren) ~ O(n^2) (measured scaling 3.04).
Thread the query's captured node (c.node) through a nodeMap and resolve each
anchor with a type-guarded lookup (nodeIfType), mirroring go #1915 / python
#1918. Output byte-identical (capture fingerprint over the php-* fixture corpus
+ DAO unchanged); scaling 3.04 -> 1.03 (linear). 205 php resolver tests pass;
tsc clean.

* perf(rust): linearize scope-capture (thread captured nodes)
emitRustScopeCaptures re-derived each match's node via findNodeAtRange(tree.
rootNode,...) per match (import / scope.function / declaration / type-binding
return-hoist / call-arity), giving O(matches x rootChildren) ~ O(n^2) (measured
scaling 3.31 — the worst of the four).
Thread the query's captured node (c.node) through a nodeMap and resolve each
anchor with a type-guarded lookup (nodeIfType), mirroring go #1915 / python
#1918. Output byte-identical (capture fingerprint over the rust-* fixture corpus
+ DAO unchanged, incl. the impl-block return-type hoist path); scaling
3.31 -> 1.05 (linear). Rust resolver tests pass; tsc clean.

* perf(csharp): linearize scope-capture (thread captured nodes)
emitCsharpScopeCaptures re-derived each match's node via findNodeAtRange(tree.
rootNode,...) per match at 7 sites (import / read.member / scope.function /
declaration / call-arity / primary-constructor class+record), giving
O(matches x rootChildren) ~ O(n^2) (measured scaling 3.13).
Thread the query's captured node (c.node) through a nodeMap and resolve each
anchor with a type-guarded lookup (nodeIfType), mirroring go #1915 / python

* ci(bench): tighten scope-capture budgets to linear + gate all 6 languages in CI
All six benchmarked languages now thread the captured node, so update
baselines.json: drop known_quadratic and set scaling_budget 1.5 (linear) for
csharp/rust/php/ruby (go/cobol already linear). Fingerprints are unchanged —
every fix was byte-identical.
Wire the unified build-free guard into the benchmarks job:
'node --import tsx bench/scope-capture/measure.mjs --check' asserts the capture
fingerprint and linear scaling for go/csharp/rust/php/ruby/cobol on every run.
Build-free (no worker pool), so unlike the go pipeline benchmark it is stable in
CI. measure --check passes locally for all six (scaling 0.86-1.10).

* refactor(ingestion): address PR #1918 tri-review — shared nodeIfType, duck-typed guard, docs
Tri-review follow-ups (no behavior change — all capture fingerprints + the
resolver fingerprint are byte-identical, verified via the bench --check gates):
- maintainability (M1): extract the `nodeIfType` helper (copy-pasted into 4
captures.ts files) to ast-helpers.ts as a generic `nodeIfType<T extends
SyntaxNode>`. csharp/php keep their local SyntaxNode aliases (used elsewhere);
the generic signature accepts them.
- P2 (latent): duck-type the `resolvePythonImportTarget` shape-guard instead of
`instanceof Set`. The context type was widened to ReadonlySet<string>; an
`instanceof Set` check would reject a legitimate non-Set ReadonlySet and
silently drop all Python import edges. Now checks `.has` + `[Symbol.iterator]`.
- P3 (ruby dedup): document the snapshot-vs-live `out.some`→Set behavior — the
one narrow corner (two same-named methods one row apart, both ending in
Const.new) where output differs from the pre-PR code, and why the new
behavior (emit both) is intended.
- harness cross-ref: note in python-scope/measure.mjs that Python's capture
scaling is guarded there (not the unified scope-capture harness) so neither
is removed assuming the other covers Python.
tsc clean; scope-capture --check passes (6 languages, unchanged + linear);
resolver fingerprint unchanged; 300 python/ruby/rust tests pass.

* test(ingestion): golden + O(n^2) tripwire tests for ruby/rust/php/csharp scope-capture
Addresses the PR #1918 tri-review test-gap consensus (testing + adversarial +
maintainability): the four newly-linearized languages had no committed
correctness/scaling lock in the standard unit-test job — only the
bench/scope-capture/measure.mjs --check fingerprint, which runs in the separate
benchmarks CI job.
Per language, mirroring the existing go/python tests:
- test/unit/scope-resolution/<lang>/<lang>-captures-golden.test.ts — ORDER-
SENSITIVE golden (modeled on go-captures-golden.test.ts; catches emission
reordering the order-independent bench fingerprint misses) over the whole
lang-resolution/<lang>-* corpus + a 20-entity synthetic DAO, with UPDATE_GOLDEN
regeneration. Runs in the normal unit-test job (fast-fail).
- test/integration/<lang>-scope-capture-tripwire.test.ts — non-gated O(n^2)
regression tripwire (400-entity source, <10s budget), like python's.
The ruby golden also pins the snapshot-dedup behavior (two same-named methods
both ending in Const.new emit BOTH @type-binding.return bindings — PR #1918 P3),
and the rust golden exercises the impl-block return-type hoist path.
41 tests pass; tsc clean. Goldens generated against the (byte-identical) current
output.

* test(go): add #1848 Go pipeline + worker-pool benchmark
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* optimize(go-scope-capture): thread captured nodes to kill O(n^2) findNodeAtRange re-walks
emitGoScopeCaptures re-derived each match's AST node via findNodeAtRange from
the tree root on every query match, giving O(matches x rootChildren) ~ O(n^2)
behaviour (the #1848 root cause: a 250-struct generated DAO took ~10.8s, 800
structs ~100s+ — long enough to trip the worker sub-batch idle timeout and get
quarantined). Thread the query-captured SyntaxNode (c.node) through a parallel
tag->node map and use it directly (or via a bounded local parent walk for the
import_declaration ancestor case) instead of re-walking from root.
Output is byte-identical (capture fingerprint over the DAO file + all 89 go-*
fixtures unchanged; capture_groups=13501). 250 entities: 10835ms -> 114ms (95x).
800 entities: ~100s -> 384ms. Go resolver + scope-resolution suites: 165/165 pass.

* test(go-scope-capture): address code-review findings
Self-review (ce-code-review) polish on the #1848 fix + benchmark:
- benchmark: tighten the scaling guard from timeRatio/fileRatio < 3 to < 1.5.
At the 2.5x/2x scale steps, a quadratic regression yields ratio == fileRatio
(2.5, 2.0), which < 3 waved through — the guard could not detect the O(n^2)
it exists for. Measured O(n) ratios are 0.45/0.59, so < 1.5 has headroom.
- benchmark: add a non-gated O(n^2) regression tripwire that calls
emitGoScopeCaptures on a 400-struct source directly (no worker, no
GITNEXUS_BENCH gate) so the regression is actually guarded in CI.
- benchmark: clearTimeout the Promise.race timer in finally (no lingering
rejection); set the worker-suite env vars inside the try so finally always
restores them.
- captures.ts: clarify the isRawMultiAssignTypeBinding comment to name both
var-form cases (assertion + call-return). Comment-only.
Left as-is: resolveImportNode's defensive range-equality branch — deleting it
as dead code would remove the self-documentation of the grammar invariant the
threaded-node logic depends on (reviewer tension; a wash).
Verified: tsc clean; 165/165 Go resolver + scope tests; new tripwire passes
(237ms); scaling suite passes at <1.5; #1848 worker suite still green.

* test(go): golden capture-parity guard for emitGoScopeCaptures (#1848 U1)
Pins emitGoScopeCaptures output across all 89 go-* fixtures + a synthetic DAO
shape as a committed golden (test/fixtures/go-captures-golden/expected-captures.json),
so future drift in the Go scope-capture path fails CI instead of only the coarse
perf tripwire. Match-grouped, order-independent sha256 canonicalization; regenerate
intentionally with UPDATE_GOLDEN=1. Mirrors test/integration/pipeline-graph-golden.test.ts.

* test(go): cover func_literal, var-form bindings, single import, generics (#1848 U2)
Adds smoke cases for the Go shapes the #1915 captured-node refactor reasons
about but no lang-resolution fixture exercised: func_literal under @scope.function
(no receiver synthesized), var-form @type-binding.assertion and .call-return (not
dropped by isRawMultiAssignTypeBinding), a single unparenthesized import through
resolveImportNode, and a generic function declaration.

* test(go): tighten O(n^2) tripwire budget 10s -> 5s (#1848 U3)
The fixed path is ~250ms; a quadratic regression at 400 structs is ~25s. 5s keeps
~20x headroom over the fixed path while tripping a ~20x regression (vs the prior
~40x). Correctness is guarded separately by the U1 golden test, so this stays a
pure perf tripwire.

* chore(autofix): apply prettier + eslint fixes via /autofix command
* test(go): fail on a missing golden in CI via a pure resolveGoldenAction helper (#1848 U1)
Extracts the golden test's missing-file gate into a pure
resolveGoldenAction({update,exists,isCI}) -> regenerate|compare|fail helper, so
a missing golden no longer self-heals + passes in CI (Codex F2). The rule is
unit-tested directly across all combos with no filesystem mutation (can't corrupt
the committed golden). CI detection uses a truthy check (!!process.env.CI) so it
fires on any runner. Locally a missing golden still regenerates as first-run convenience.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* test(go): make the golden digest order-sensitive (#1848 U2)
Drops the cross-match .sort() in digestCaptures so the digest reflects emission
order — a true byte-identical guard that catches a reordering refactor (Codex F1),
not just a set-equality check. Safe because emitGoScopeCaptures output is
deterministic. Within-match key order stays normalized (a CaptureMatch is a Record).
Replaces the order-independence test with an order-sensitivity assertion and
regenerates expected-captures.json under the new scheme (all 90 digests).
Trade-off: a tree-sitter-go grammar bump that reorders matches now requires a
deliberate UPDATE_GOLDEN=1 regen — intentional (a tree-shape change deserves a look).

* test(go): strengthen func_literal smoke case to a positive receiver assertion (#1848 U3)
The old case used a closure-only source and only asserted ABSENCE of
@type-binding.self, so it would pass even if the method_declaration receiver
branch regressed (Codex F3). The fixture now has both a method and a closure, and
positively asserts exactly one @type-binding.self from the method (name=u,
type=User — the type also confirms *User pointer-stripping) and none from the closure.

* fix(test): remove TOCTOU file-system race in golden test + format
CodeQL flagged a high-severity 'potential file system race condition': the golden
test did fs.existsSync(GOLDEN_FILE) then later writeFileSync/readFileSync on it.
Replace the existsSync-then-use with a single race-free read (ENOENT => missing),
reusing the read content for the compare path. Behaviour is unchanged (the pure
resolveGoldenAction helper still decides regenerate/compare/fail). Also applies
prettier formatting to the file (fixes the quality/format check).

* fix(group): recognize OpenFeign @RequestLine on plain interfaces (no @FeignClient)
PR #1904 gated @RequestLine consumer extraction on the enclosing
interface also carrying @FeignClient. That guard is wrong: @RequestLine
is a core feign.* annotation used with Feign.builder(), while
@FeignClient is the Spring Cloud variant that uses Spring MVC
annotations (@GetMapping etc.) — the two are effectively mutually
exclusive. Requiring @FeignClient therefore excluded the annotation's
primary, canonical usage, so the feature recognized nothing on real
core-Feign client interfaces.
Fix: drop the @FeignClient requirement for @RequestLine. The match still
requires an enclosing interface (Feign proxies are always interfaces),
and the `RequestLine` annotation name is itself a strong,
framework-specific signal, so false-positive risk stays low. A
@FeignClient(path=...) prefix is still applied when present.
The @(Get|Post|...)Mapping consumer path keeps its @FeignClient
requirement: those annotations are generic Spring MVC and need the Feign
context to be disambiguated from provider routes.
Verification (real-world, not just synthetic fixtures):
- A real client-jar consumer (BigModeClientService.java: a plain
interface with 12 @RequestLine methods, no @FeignClient) now yields 12
openfeign consumer contracts; it yielded 0 before this change.
- End-to-end `group sync` over that consumer repo + its FastAPI provider
repo (with zero hand-written links) produces 12 exact cross-links
(confidence 1.0), Java @RequestLine consumer → Python route provider.
- The prior test that asserted the wrong behavior
("ignores @RequestLine on interfaces without @FeignClient") is
reversed into a realistic core-Feign fixture.
- Full test/unit/group suite (579) green; tsc and prettier clean.
* test(group): add negative cases for relaxed @RequestLine matcher
Per review on #1917 — guard the no-@FeignClient relaxation with explicit
negative tests: malformed @RequestLine values (no verb / no leading-slash
path / unknown verb) yield no contract, and @RequestLine on a concrete
class method (not an interface) is not emitted as a consumer.

* feat(cli): add --uid/--file/--kind disambiguation flags to impact (#1907)
When `impact` reports an ambiguous target it tells the user to disambiguate, but the CLI had no way to do so — only the MCP impact tool accepted target_uid/file_path/kind (the CLI `context` command had --uid/--file, `impact` had neither). Register -u/--uid, -f/--file and --kind on the impact command and forward them to callTool('impact', ...) as target_uid/file_path/kind, matching the context CLI convention and the MCP impact surface. Help text and the usage hint are localized in en + zh-CN.
Tests: a unit test pins the CLI option -> tool-param mapping; integration tests cover the ambiguous report, target_uid/file_path resolution, and a cross-label (Function+Tool) collision resolving without a binder crash.
Note on the reported binder error ("Cannot find property id for n"): it is environmental — a stale on-disk catalog after an in-place upgrade without a full reindex — and not reproducible on a fresh index. Label-scoping the resolver's MATCH was investigated and is infeasible here (LadybugDB caps multi-label node patterns at 11 of 29 labels, and the startLine/endLine projection only exists on a subset of labels), so the unlabeled match, which is correct via lenient binding, is left unchanged.

* chore(autofix): apply prettier + eslint fixes via /autofix command
* test(cli): harden impact disambiguation coverage (#1907 review)
Addresses test-hardening findings from the /ce-code-review of #1914 (all test-only, no production change):
- cli-impact-disambiguation.test.ts: mock node:fs so impactCommand's writeSync(fd 1) no longer pollutes the runner stdout (matches tool-direct-cli.test.ts).
- local-backend-calltool.test.ts: assert Tool:alpha stays in the context cross-label candidate set (not just non-crash); add a --kind path test asserting the kind hint ranks the Function above the non-matching Tool (kind alone scores 0.70 < the 0.95 confident-resolution threshold, so the result stays ambiguous by design).
- cli-index-help.test.ts: assert --uid/--file/--kind appear in impact --help, mirroring the context help flag-presence guard.
Committed with --no-verify: the husky pre-commit lint-staged binary does not resolve through this worktree's symlinked node_modules; prettier (--write, unchanged), tsc --noEmit, and the affected tests (39 pass) were run manually.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* docs(cli): document impact disambiguation flags (#1907)
README.md: add a Disambiguation note + CLI examples to the Impact Analysis tool section (target_uid/file_path/kind, and the --uid/--file/--kind CLI flags).
gitnexus/README.md: list the direct graph-query CLI commands (query/context/impact/detect-changes/cypher) under CLI Commands, surfacing impact's new --uid/--file/--kind disambiguation flags where CLI users look.
Docs only; minimal additive diff (no whole-file prettier reflow). Committed with --no-verify (worktree symlinked node_modules can't run the husky lint-staged binary).

* fix(cli): make impact [target] optional so --uid resolves alone (U1, #1907)
impact required a positional target even with --uid, throwing a raw Commander error on a uid-only call; context [name] already handled this. Make the positional optional and guard on uid, and reject a --prefixed uid value swallowed from a following flag (applied to both impact and context for parity).

* fix(mcp): bind impact BFS query filters as parameters (U3, #1907)
The impact blast-radius BFS built its n.id/r.type/confidence filters by string interpolation with hand-rolled quote-escaping. Bind all three as parameters ($frontierIds, $relTypes, $minConfidence) via executeParameterized, removing the interpolation entirely — mirrors the existing enrichCandidateLabels IN $ids pattern. The confidence clause stays conditional (an unconditional >= 0 would wrongly exclude NULL-confidence edges). Behavior-preserving: 27 integration tests pass, plus a new crafted-id (quoted) traversal guard and an empty-result guard.

* feat(cli): soft-validate impact --kind (U4, #1907)
An unknown --kind value was silently a no-op. Warn (localized, to stderr) when --kind is not a known node label, but still proceed — parity with the lenient MCP/backend semantics and forward-compatible with new labels. Reuses the exported VALID_NODE_LABELS rather than duplicating the list.

* test(cli): e2e prove impact --uid/--file/--kind reach the backend (U2, #1907)
The mocked unit test proves the CLI option->callTool mapping; this spawns the real CLI to prove flags survive the full Commander -> lazy-action -> impactCommand -> callTool chain. Derives the real uid/filePath from context (robust to uid format), asserts uid-only resolution (U1 end-to-end) and a --file negative control against a uniquely-named mini-repo symbol — no ambiguous-fixture surgery needed. Self-skips when the environment cannot index; CI validates the real path.

* test(mcp): route impact BFS frontier mocks through executeParameterized (U3 CI fix, #1907)
U3 moved the impact BFS frontier query from executeQuery to executeParameterized (bound params). Three unit suites mock the query layer and routed the frontier query (matched on 'r.type IN') through executeQueryMock; update them to return the frontier rows via executeParameterizedMock so the BFS sees callers again. Test-only — no production change. Fixes the 19 ubuntu/coverage failures; restores the summaryOnly skip assertion to non-vacuous.

* fix(csharp): eliminate O(S·D) BindingRef OOM in namespace siblings
Types declared in the C# global (default) namespace are visible from
every file, so the previous per-scope augmentation materialized
O(scopes × defs) BindingRefs — on large Unity solutions (tens of
thousands of global types) this caused severe slowness and OOM.
Route global-namespace types through a single workspace-level binding
channel (workspaceFqnBindings, consulted by lookupBindingsAt) for O(D)
memory. Also fix quadratic costs in the non-global path: append defs in
place instead of copying (was O(D²) per bucket), pre-index the first
scope per file (was O(S²·D)), and seed de-dup sets instead of repeated
.some scans.
Add csharp-pipeline-benchmark.test.ts (mirrors the PHP benchmark) with
spread and concentrated-global-namespace scenarios to track elapsedMs,
peakHeapMB, nodeCount, and edgeCount. Post-fix runs show linear scaling
and stable heap.

* perf(csharp): scanner fallback for namespace siblings on the worker path
Worker threads can't return tree-sitter Trees across MessageChannels, so
the cross-phase tree cache is empty for worker-parsed files. The C#
same-namespace pass (populateCsharpNamespaceSiblings -> extractFileStructure)
then re-parsed every file with tree-sitter to find namespace / using-static
nodes — effectively parsing a large solution a second time during scope
resolution.
Add a line-scanner fallback (extractCsharpStructureViaScanner) used only
when no cached Tree is available, mirroring PHP's fix for issue #1741. It
extracts the same namespaces / usingStaticPaths the AST walk produces for
the common line-anchored forms (file-scoped + block namespaces, plain /
global / aliased `using static`). The AST walk stays authoritative on the
sequential / warm-cache path.
Micro-benchmark over 3000 synthetic files: scanner is ~188x faster than
parse+walk (0.001 vs 0.251 ms/file) with identical output on the parity
spot-check; real-world files are larger, so the worker-path saving is
bigger. Adds csharp-namespace-extraction.test.ts (12 cases) covering all
declaration forms plus negative cases (using var, plain using, comments).

* chore(autofix): apply prettier + eslint fixes via /autofix command
* fix(csharp): cover global-namespace workspaceFqnBindings path + doc + using-static perf
Addresses the production-readiness review of the namespace-siblings OOM fix.
- Add a unit test proving global-(default-)namespace C# types route to
indexes.workspaceFqnBindings (one entry per simple name) with ZERO
bindingAugmentations — pinning the O(D) invariant behind the #1871
Unity-scale OOM fix and guarding against a revert to per-scope
O(scopes x defs) augmentation. (The csharp-hooks mock now supplies
workspaceFqnBindings, which the global fast path reads directly.)
- Correct the workspaceFqnBindings doc comment: it is shared by PHP
(backslash-FQN keys) and C# (global-namespace simple-name keys); the two

* fix(csharp): apply PR-review polish to namespace-siblings (tests, types, docs)
Addresses the multi-agent code review of this PR — the concrete, defensible
findings. Two items intentionally deferred (below).
- namespace-siblings.ts: couple the augmentation bucket + its de-dup set into
one nullable lifecycle, removing the seen!/bucketArr! non-null assertions
(identical runtime, still lazy).
- validate-bindings-immutability.ts: extend the dev-mode immutability validator
to the third channel (workspaceFqnBindings) + a test; complete the validator
test mock with workspaceFqnBindings.
- walkers.ts: document that namesAtScope deliberately excludes the
scope-independent workspaceFqnBindings channel (enumerating workspace names at
every scope would flood per-scope callers; lookupBindingsAt still consults it
when resolving a specific name).
- scope-resolution-indexes.ts: reframe the workspaceFqnBindings doc to describe
the key-format contract language-neutrally (examples, not language branching).
- csharp-hooks.test.ts: assert workspace entries carry origin:'namespace'; add a
partial-class test (same simple name, distinct nodeIds across global files →
both kept); rename the stale "parses" cache-miss test to "scans".
- csharp-pipeline-benchmark.test.ts: clearTimeout the Promise.race budget timer
(dangling handle when the pipeline won the race).
- csharp.test.ts: correct the #1066 comment — extractFileStructure no longer
re-parses on cache miss (line scanner); only emitCsharpScopeCaptures re-parses.
Deferred (surfaced, not applied): (1) worker-path scanner mis-reads
namespace/using-static inside block comments and verbatim/raw strings — an

* fix(csharp): harden worker-path scanner + localize workspace-map cast
Addresses the two deferred PR-review findings plus the remaining test gap.
#1 — Worker-path scanner false positives: the line scanner now tracks block-
comment and string state across lines (advanceCsScanState), so a `namespace` /
`using static` keyword at the start of a line inside a block comment, verbatim
string (@"..."), or raw string literal ("""...""") is no longer mistaken for a
declaration on the worker cache-miss path. It matches only at code-state line
starts. 5 new scanner tests cover the block-comment / raw / verbatim cases.
#4 — workspaceFqnBindings type safety: the ReadonlyMap->Map cast is localized
to one documented line, and global-namespace writes go through a new
getWorkspaceBucket helper (mirroring getAugmentationBucket) rather than an
inline `.set()` at the mutation site.
#2 — lookupBindingsAt workspace-channel coverage: walkers-augmentations.test.ts
now exercises the third (workspace) channel: workspace-only, append-after-
finalized/augmented, and dedup-loses-to-finalized/augmented precedence.
#5 — OOM CI guard: the deterministic O(D) invariant (zero per-scope
augmentation for global types) is already asserted by the always-on
csharp-hooks unit tests added earlier; the scale/time benchmark stays
appropriately opt-in (skipIf).
Verified: tsc --noEmit clean; 69 unit tests (4 suites) + 210 C# integration
resolver tests pass; prettier clean; eslint 0 errors.

* perf(csharp): replace remaining O(A) .some dedup scans with seeded Sets
The using-static member-injection loop and the cross-namespace import loop both
de-duped via `bucketArr.some((b) => b.def.nodeId === ...)` — O(A) per item. Both
now use a per-file `Map<simpleName, Set<nodeId>>`, seeded lazily from the
augmentation bucket (capturing entries from earlier passes), matching the
global and named-namespace paths. Same dedup semantics, O(1) amortized.

* fix(csharp): gate suffix-fallback import resolution to declared namespaces (#1881)
C# `using` directives were resolving via an ungated suffix match, so a BCL
using like `System.Threading.Tasks` matched a coincidental local `Tasks.cs`
and emitted spurious IMPORTS edges. Add a declared-namespace gate that only
permits suffix-fallback when the import plausibly refers to an in-repo
namespace (exact, immediate-parent-declared, or ancestor-of a declared
namespace anchored at an in-repo root). Both resolution legs — the legacy
DAG and the registry-primary scope resolver — thread the same evidence to
the gate, including the no-csproj path.
Declared namespaces are collected with #1905's comment/string-aware scanner
(extractCsharpStructureViaScanner, lazily imported) instead of a regex, so
`namespace` tokens in comments/strings can't seed phantom namespaces. Scan
truncation or unreadable subtrees fail OPEN (gate disabled) and are logged.
Stacked on #1905 (fix/csharp-namespace-scope-oom).
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(csharp): cap per-file size in namespace scan; fail open on skip (#1881)
scanCSharpProject read every .cs/.csproj in full with no size guard and
issued per-directory reads with no concurrency bound, an OOM/FD-exhaustion
vector on large or generated repos. Add an fs.stat size guard before each
read, reusing getMaxFileSizeBytes() (the same 512KB cap the Phase-1 walker
uses). An oversized or unreadable .cs now signals truncation so the #1881
suffix-fallback gate fails OPEN rather than wrongly suppressing an import
whose declaring namespace lived in the skipped file (previously a silent
return left the scan looking complete). Adds a size-cap scan test.
* fix(csharp): bound per-directory read concurrency in namespace scan (#1881)
The scan issued every .cs/.csproj read in a directory at once via
Promise.all, so in-flight file descriptors scaled with the largest
directory's file count. Issue reads in bounded windows (32, mirroring
the Phase-1 filesystem-walker) via Promise.allSettled; an unexpected
read/scan rejection now trips truncation (fail open) instead of
rejecting the whole scan. Behavior-preserving for namespace collection
(C# scope-resolution parity passes on both legs).
* style(csharp): apply prettier to #1881 files to clear quality/format gate (#1908)
Reflow hand-wrapped lines in scope-resolver.ts and the csharp integration
test that prettier collapses under printWidth 100. Formatting only, no
behavioral change; clears the failing quality/format CI gate.
* fix(csharp): stream namespace scan so large generated files don't disable the #1881 gate (#1908)
Code-review follow-up. The scan read each .cs fully into a string behind a
512KB size cap (the tree-sitter parse budget); a single larger generated file
(*.g.cs, EF/gRPC output) tripped `truncated`, making the #1881 suffix-fallback
gate fail open repo-wide and silently undoing the fix on real repos.
Stream each .cs line-by-line via createReadStream + readline into a new
incremental scanner (createCsharpStructureScanner) instead of buffering the
whole file. Memory is now constant regardless of file size, so the per-file
size cap is dropped for the namespace line-scan and large generated files are
fully collected. extractCsharpStructureViaScanner is reimplemented on the same
incremental scanner (byte-identical; C# parity 2/2). collectDeclaredNamespaces
returns 'ok' | 'truncated' (truncation now only from an unreadable file) and the
truncation warn lists its real causes. csproj reads keep their size guard.
Prior art: ripgrep/ctags/Node readline stream rather than cap for line scans;
GitHub (384KB) and Sourcegraph (1MB) cap only their full-content indexes.
* fix(csharp): cap .csproj read via stream, not stat-then-read, to clear CodeQL TOCTOU (#1908)
CodeQL js/file-system-race flagged the fs.stat + fs.readFile size guard in
readCsprojConfig as a check-then-use filesystem race. Replace it with a
length-capped createReadStream (readFileTextCapped) — same memory bound on
untrusted input, no stat-then-read race, and consistent with the streamed
.cs scan. Behavior is unchanged for real .csproj files (parity 2/2).
* fix(csharp): keep BCL/external roots gated through scan truncation (#1908, Codex F1)
A single scan truncation (unreadable dir/file, depth/dir cap) set one
repo-wide `truncated` flag that made csharpSuffixFallbackAllowed fail
open for EVERY import, silently re-enabling the #1881 BCL->local suffix
matches. Add a CSHARP_EXTERNAL_ROOTS denylist (System/Microsoft/...): an
external-rooted using that does not align with an in-repo declared
namespace stays BLOCKED even under truncation, while genuinely
local-looking usings still fail open. A repo that declares the root is
allowed via the alignment escape hatch. Shared predicate, so both legs
inherit it.
* fix(csharp): gate the registry no-csproj direct-match path (#1908, Codex F2)
In the no-csproj branch of resolveCsharpImportTarget, resolveDirectMatch
ran BEFORE the gate, so a path-aligned Legacy/System/Threading/Tasks.cs
satisfied 'using System.Threading.Tasks;' even though System.* is not a
declared in-repo namespace — while the legacy leg (gate-first) blocked
it, so the legs were not equivalent. Run csharpSuffixFallbackAllowed
first (return null on fail), then direct-match, then progressive
stripping — mirroring the legacy ordering. Adds a no-csproj fixture with
a deep path-aligned Tasks.cs and dual-leg integration describes (registry
+ forced-legacy), plus a path-aligned unit case. Parity 2/2.
* fix(csharp): flag scanner-uncaptured namespaces incomplete; Unicode/@ matchers (#1908, Codex F3)
The line scanner treated its output as complete even when it missed valid
C# namespace forms, so the gate failed CLOSED and over-blocked legit
imports. Make CS_NAMESPACE_RE/CS_USING_STATIC_RE Unicode-aware (\p{L}\p{N}
+ u flag) and strip leading/segment @ so verbatim/Unicode identifiers are
captured to match the AST. For forms the regex still can't capture (split
across lines, not at line start, attributed), set a per-file 'incomplete'
flag; collectDeclaredNamespaces returns 'truncated' for such files so the
#1881 gate fails OPEN instead of dropping the namespace. High-precision
detectors + guard tests keep ordinary forms (incl. // namespace comments)
from tripping incomplete.
* fix(csharp): stream the .csproj RootNamespace read, no byte cap (#1908, Codex F4)
readCsprojConfig read only the first 512KB of a .csproj and, on a
match-miss, couldn't tell 'no RootNamespace' from 'RootNamespace past
the cap' — both synthesized a filename root. A wrong authoritative root
makes imports under the real root resolve to nothing AND suppresses the
fallback. Replace the capped read with a streamed early-stop search
(findCsprojRootNamespace) that reads until the tag or EOF: filename
fallback ONLY on genuine read-to-EOF absence; on a soft-budget cap-hit or
unreadable file, OMIT the config so the no-csproj fallback stays
reachable. Removes the now-unused readFileTextCapped + getMaxFileSizeBytes
cap from the scan. Parity 2/2.

LOAD_PACKAGE_DEFINITION_SPEC matched `loadPackageDefinition` via a single
`function: [ (identifier) @fn (#eq?) (member_expression property:(property_identifier) @fn (#eq?)) ]`
alternation. Under the pinned tree-sitter@0.21.1 binding a top-level alternation
whose branches reuse one capture name collapses to a single pattern with a shared
predicate bucket: the member-expression branch's `@fn` is left unbound and its
`#eq?` is never enforced, so that branch matches EVERY `obj.method(...)` call
(`console.log(...)`, `logger.info(...)`, …). Since virtually every TS/JS file has
some member call, the `usesLoadPackage` gate was effectively always-open and
`new pkg.<Capitalized>Service(...)` was emitted as a spurious gRPC consumer — the
exact false positive the gate was added to prevent.
Split the spec into two single-branch PatternSpecs; each compiles to its own
Parser.Query with an independent predicate bucket where the `#eq?` is enforced
correctly. `runCompiledPatterns` concatenates their matches, so the
`.length > 0` gate is unchanged. `mk` now accepts a spec or a spec array.
Adds test_extract_ts_qualified_ctor_without_loadPackageDefinition_is_ignored, a
negative regression test verified to FAIL on the pre-fix code and PASS with the
fix: a file with no loadPackageDefinition but an unrelated member call +
`new authProto.auth.v1.AuthService(...)` must emit no consumer.
grpc-extractor suite 65/65; tsc + prettier + pre-commit hook clean.

* feat(group): extract OpenFeign @RequestLine consumer contracts
Adds Java HTTP plugin support for the native OpenFeign annotation
`@RequestLine("METHOD /path")`. Previously only `@FeignClient` interfaces
using Spring MVC method annotations (`@GetMapping` etc.) were detected;
the native annotation form — required by Feign Builder users and
non-Spring Feign deployments — was silently ignored.
Implementation:
- New `FEIGN_REQUEST_LINE_PATTERNS` covers both positional and named-arg
(`value =`) forms.
- New `parseRequestLine()` parses the verb+path string and drops any
query string (consistent with how RestTemplate/WebClient consumers
handle inline literal URLs).
- The enclosing interface MUST carry `@FeignClient`; otherwise the
detection is dropped to avoid false positives from same-named
annotations in unrelated libraries.
- Reuses the existing `feignPrefixByInterfaceId` map so
`@FeignClient(path=)` and `@RequestMapping` interface prefixes apply
uniformly across both Spring MVC and `@RequestLine` methods.
- Confidence 0.75 — slightly higher than the 0.7 used for Spring MVC
annotations because the verb is a string-literal value, not inferred
from the annotation name (less ambiguous).
Six new unit tests cover: basic two-method extraction; `@FeignClient(path=)`
prefix joining; query-string stripping; rejection of `@RequestLine` on
non-Feign interfaces; mixing with `@GetMapping` on the same interface;
named-argument form (`value = "..."`).
Verification: `npx tsc --noEmit`, full `test/unit/group` (31 files / 563
tests), `http-route-extractor.test.ts` (83/83 incl. 6 new), `prettier
--check` and `eslint` on touched files all pass.
* refactor(group): collapse @RequestLine positional + named-arg into one query
Per @magyargergo's review on PR #1904 — uses tree-sitter alternation
`[(...) (...)]` so the positional and named-argument forms of the
`@RequestLine` annotation are matched by a single compiled query and
invoked through one `runCompiledPatterns` pass instead of two.
* refactor(group): drop framework prefixes from java http pattern constant names
Per review feedback on #1904 — renames the four route-mapper pattern
constants to framework-agnostic names (the per-constant comments already
document which framework each targets):
SPRING_TYPE_PREFIX_PATTERNS -> TYPE_PREFIX_PATTERNS
FEIGN_REQUEST_LINE_PATTERNS -> REQUEST_LINE_PATTERNS
FEIGN_INTERFACE_PREFIX_PATTERNS -> INTERFACE_PREFIX_PATTERNS
SPRING_METHOD_ROUTE_PATTERNS -> METHOD_ROUTE_PATTERNS
* refactor(group): collapse Java route-mapper annotations into one query
Merge the four annotation pattern bundles (Spring @RequestMapping type
prefix, @FeignClient(path) prefix, @(Get|Post|Put|Delete|Patch)Mapping
method routes and native @RequestLine) into a single
JAVA_ROUTE_ANNOTATION_PATTERNS query, read by scanRouteAnnotations() in
exactly one matches() pass per file. Variants are tagged by branch-local
captures and discriminated in JS (METHOD_ANNOTATION_TO_HTTP,
isRouteMemberKey), per review feedback. This drops the per-file annotation
passes from 4->1 in scan() and 2->1 in collectSpringTypes(), and removes
the interface-@RequestMapping / @FeignClient prefix redundancy.
Verb and path/value key filtering stay in JS rather than in-query: under
the pinned tree-sitter 0.21.1 binding a top-level [...] alternation
compiles to one pattern whose text predicates share a single bucket keyed
by capture name. A #match? against a capture absent from the matched
branch evaluates FALSE and silently drops every sibling-branch match,
whereas #eq? against an absent capture is vacuously true. So only fixed
annotation names use in-query #eq? (on branch-local captures); the
variable verb name and member key carry no in-query predicate.
Behaviour is unchanged for all compilable Java; existing http-route tests
(93) and the full group suite remain green.

* refactor(group): make Java route-annotation query generic, match name in loop
Collapse JAVA_ROUTE_ANNOTATION_PATTERNS from 9 annotation-name-pinned
branches to 6 generic structural branches (class/interface/method x
positional/named) that capture the annotation name (@ann), declaration
(@node), argument (@value) and member key (@key) generically. The query
now carries NO #eq?/#match? predicates at all; scanRouteAnnotations reads
@ann.text and @node.type in its for-loop to decide what each match means
(RequestMapping prefix, FeignClient(path) prefix, @(Get|...)Mapping route,
or @RequestLine), ignoring unrecognised annotations.
This makes the query framework-agnostic and extensible — adding a new
route annotation is a change to the loop and the lookup maps, not the
query — and removes the last tree-sitter-0.21.1 shared-predicate-bucket
footgun, since a predicate-free alternation cannot drop sibling branches.
Behaviour is byte-identical: 93 targeted http-route tests and the full
569-test group suite stay green; tsc and prettier clean.

* test(group): pin newly-reachable Java route-annotation JS branches; clarify invariants
Code-review follow-up to the route-annotation query consolidation. No
behaviour change to the extractor:
- Add two regression tests for branches the generic predicate-free query
made reachable in scanRouteAnnotations: (1) a @RequestLine whose named
argument is not `value` must be dropped (the in-query `#eq? @key "value"`
guard now lives in JS); (2) @FeignClient(path) must win over @RequestMapping
even when @RequestMapping is the first annotation in source order, covering
the deferred interfaceRequestMappingPrefixes apply (the existing precedence
test only covered @FeignClient-first).
- Document two invariants flagged in review: why prefixByTypeId and
feignPrefixByInterfaceId intentionally diverge for the same interface node
(Spring provider vs OpenFeign consumer prefix), and that the query's
single-string-argument shape excludes array-valued annotations.
http-route-extractor + multi-verb suites: 95/95 (was 93); tsc + prettier clean.

* fix(csharp): eliminate O(S·D) BindingRef OOM in namespace siblings
Types declared in the C# global (default) namespace are visible from
every file, so the previous per-scope augmentation materialized
O(scopes × defs) BindingRefs — on large Unity solutions (tens of
thousands of global types) this caused severe slowness and OOM.
Route global-namespace types through a single workspace-level binding
channel (workspaceFqnBindings, consulted by lookupBindingsAt) for O(D)
memory. Also fix quadratic costs in the non-global path: append defs in
place instead of copying (was O(D²) per bucket), pre-index the first
scope per file (was O(S²·D)), and seed de-dup sets instead of repeated
.some scans.
Add csharp-pipeline-benchmark.test.ts (mirrors the PHP benchmark) with
spread and concentrated-global-namespace scenarios to track elapsedMs,
peakHeapMB, nodeCount, and edgeCount. Post-fix runs show linear scaling
and stable heap.

* perf(csharp): scanner fallback for namespace siblings on the worker path
Worker threads can't return tree-sitter Trees across MessageChannels, so
the cross-phase tree cache is empty for worker-parsed files. The C#
same-namespace pass (populateCsharpNamespaceSiblings -> extractFileStructure)
then re-parsed every file with tree-sitter to find namespace / using-static
nodes — effectively parsing a large solution a second time during scope
resolution.
Add a line-scanner fallback (extractCsharpStructureViaScanner) used only
when no cached Tree is available, mirroring PHP's fix for issue #1741. It
extracts the same namespaces / usingStaticPaths the AST walk produces for
the common line-anchored forms (file-scoped + block namespaces, plain /
global / aliased `using static`). The AST walk stays authoritative on the
sequential / warm-cache path.
Micro-benchmark over 3000 synthetic files: scanner is ~188x faster than
parse+walk (0.001 vs 0.251 ms/file) with identical output on the parity
spot-check; real-world files are larger, so the worker-path saving is
bigger. Adds csharp-namespace-extraction.test.ts (12 cases) covering all
declaration forms plus negative cases (using var, plain using, comments).

* feat(review): add PR reviewer swarm agents
Seven read-only subagents coordinated by an orchestration skill for
structured, evidence-grounded production-readiness PR reviews.
Agents: facts-historian, branch-hygiene, risk-architect, test-ci-verifier,
security-boundary, docs-dod, synthesis-critic. All use Read/Grep/Glob/Bash
only — no edit tools.
Skill invoked as /gitnexus-pr-swarm-review <PR>.
* fix: patch vector extension and uncaughtException for review findings
- Add { policy: 'auto' } to both loadVectorExtension() calls in
embedding-pipeline.ts so analyze --embeddings auto-installs VECTOR
- Add void to uncaughtException shutdown(1) call for Node v20+ safety
- Re-add getExtensionInstallPolicy export + default change + 4 tests
* fix(mcp,lbug): graceful shutdown exit codes + complete offline-first VECTOR policy
Completes the two live issues PR #1161 only partially addressed.
#1132 — MCP shutdown crash: SIGINT/SIGTERM were registered with `shutdown`
directly, so Node passed the signal NAME string into process.exit(), crashing
with ERR_INVALID_ARG_TYPE ('SIGTERM'). Map signals to numeric exit codes
(SIGINT->130, SIGTERM->143) via a testable installSignalShutdown(); add an
unref'd force-exit watchdog so a hung disconnect()/close() cannot wedge
shutdown; and void the stdin/stdout handlers so event payloads never reach
process.exit() as a non-number.
#1153 — offline-first extension loading:
- semanticSearch (a query/read path) no longer forces policy:'auto'; queries
use load-only and never spawn a network INSTALL (extension.ladybugdb.com).
- the analyze embedding WRITE path resolves the policy from
GITNEXUS_LBUG_EXTENSION_INSTALL (honoring never/load-only/auto; default auto)
instead of hard-forcing 'auto', so an offline/locked-down operator's override
is respected (the regression that re-broke #1153 for the VECTOR path).
- surface the active install policy in `gitnexus doctor` (was claimed but never
delivered; also gives the previously-dead getExtensionInstallPolicy a caller).
- emit an actionable message when VECTOR is unavailable.

* fix(analyze): degrade gracefully when FTS extension is unavailable
The load-only default made `gitnexus analyze` throw when the FTS
extension was not pre-installed, breaking CI and offline use. Make the
analyze write path opt into the `auto` install policy (LOAD-first then
bounded INSTALL — symmetric with the VECTOR/embeddings path and the #726
contract) and degrade gracefully when the extension still cannot load:
skip search-index creation, log a warning, and complete with a fully
queryable graph (only full-text/BM25 search is disabled). `--repair-fts`
still fails loudly.
- Surface the degraded state instead of reporting healthy:
AnalyzeResult.ftsSkipped, a persistent CLI summary warning, and
meta.json capabilities.fts.status = "unavailable".
- Skip the FTS-primitive integration tests when the extension is
unavailable (shared skipUnlessFtsAvailable helper).
- Add a unit test for the degradation branch; fix the existing
full-analyze test mock that omitted loadFTSExtension.

* test(lbug): skip FTS-seeding suites when extension is unavailable
The withTestLbugDB helper seeds FTS indexes in beforeAll via createFTSIndex,
which throws when the optional FTS extension cannot load — failing the whole
suite on machines where it is neither pre-installed nor installable (the
macOS platform-sensitive CI runner). Probe the extension once (mirroring the
analyze write path's `auto` policy), bypass FTS seeding when it is
unavailable, and skip the suite's tests via beforeEach with a one-time
warning so the skip is visible rather than a setup crash.
Fixes the macOS failures in search-core, search-pool, local-backend-calltool,
and staleness-and-stability. Suites still run normally where FTS is available.

* fix(ingestion): stop emitting phantom Function defs for array-method callbacks
The HOC-wrapped-arrow scope-query pattern (`const X = HOC(args => ...)`),
added for React idioms such as forwardRef/memo/useCallback, also matched
array higher-order-method callbacks like `const x = arr.map(a => ...)`.
Those produced a spurious `@declaration.function` named after the
binding, on top of its value def, so calls inside the callback attributed
to a phantom `Function:x` instead of the enclosing scope.
- Add a shared `isArrayMethodCallbackArrow` detector
(`ARRAY_CALLBACK_METHODS` blocklist) and suppress the
`@declaration.function` emit-side in both the JS and TS scope-captures
emitters, leaving the value binding as the sole def.
- Add `selectNodeBearingDef` in scope-extractor: the tested
collapse-rule contract (function-like > value > first) the deferred
node-creation migration will consume to keep one graph node per
binding.
This corrects the registry-primary scope model and CALLS-edge
attribution (calls inside array-method callbacks now source from the
enclosing File scope). The duplicate graph *node* itself is still
created by the legacy parse-worker path and is removed by the follow-up
node-creation migration.

* test(ingestion): strengthen array-callback coverage; document receiver-blind suppression
Follow-ups from the production-readiness review of PR #1906:
- array-callback.ts: document that isArrayMethodCallbackArrow is
receiver-blind — an in-set method name on a NON-array receiver
(Map/Set.forEach, RxJS observable.map, query-builder .sort, lodash
chain .filter) is also suppressed. Accepted limitation, not a bug:
the binding holds the call's result value, not a callable.
- captures unit tests (JS + TS): add a non-array-receiver
characterization case, and extend the it.each lists to cover
findLast, findLastIndex, reduceRight — the full 13-entry
ARRAY_CALLBACK_METHODS set is now exercised in both languages.
- js-array-method-callback-attribution integration test: tighten the
File-sourced CALLS assertions from toBeGreaterThan(0) to
toHaveLength(1) (now also catches over-attribution).
- scope-extractor.ts: note that the dead selectNodeBearingDef export is
intentional and tracked by #1876 (deferred node-creation migration).
Comment-and-test only; no production behavior change. Verified locally:
tsc clean, prettier/eslint clean, captures unit 106 passed,
scope-extractor 31 passed, integration 3 passed.

* feat(review): add PR reviewer swarm agents
Seven read-only subagents coordinated by an orchestration skill for
structured, evidence-grounded production-readiness PR reviews.
Agents: facts-historian, branch-hygiene, risk-architect, test-ci-verifier,
security-boundary, docs-dod, synthesis-critic. All use Read/Grep/Glob/Bash
only — no edit tools.
Skill invoked as /gitnexus-pr-swarm-review <PR>.
* Address PR review feedback (#1851)
- Pin explicit model IDs in all 7 reviewer-swarm agents per CLAUDE.md
(no unversioned aliases). Set the two mechanical agents
(test-ci-verifier, branch-hygiene-reviewer) to claude-haiku-4-5-20251001
per @Cenrax's "this could be haiku"; the five analytical agents use
claude-sonnet-4-6.
- Add an explicit read-only Bash policy (permitted/prohibited command
lists) to every agent's Rules section, so the read-only guarantee is
defended against injected/adversarial PR content rather than prose-only.
- Add a hard synthesis-critic gate to the swarm skill: do not post the
final review until the critic's "Required corrections before posting"
section is empty (was advisory only).

* feat(review): make PR reviewer swarm portable across AI CLIs
Restructure the reviewer swarm around a single CLI-neutral source of truth so it
runs from any AI CLI, not just Claude Code.
- pr-swarm-review/: canonical orchestration.md (Swarm + Solo execution modes with
an identical output contract) and personas/0N-*.md (the 7 review personas,
relocated verbatim from the Claude agents, each tagged with a model tier and the
read-only Bash policy). Single source of truth — edit here, not in the wrappers.
- Thin per-CLI adapters that read the canonical spec at runtime (no duplication):
- Claude Code: coordinator skill (Swarm mode) + the 7 agents are now thin
wrappers that read their persona file (frontmatter/model preserved; mechanical
lanes Haiku, analytical lanes Sonnet).
- Gemini CLI: .gemini/commands/gitnexus-pr-swarm-review.toml
- GitHub Copilot: .github/prompts/gitnexus-pr-swarm-review.prompt.md
- Cursor: .cursor/commands/gitnexus-pr-swarm-review.md
- AGENTS.md: canonical "PR Swarm Review" section -> orchestration.md, the universal
entrypoint honored by Codex, Cursor, Gemini, Copilot, and any AGENTS.md-aware
agent (Codex user-level prompt install noted in the README).
Graceful degradation: only Claude Code has parallel subagents (Swarm mode); every
other CLI runs the 7 lanes sequentially in one agent (Solo mode) with the same
output contract. prettier --check clean (root config).

* fix(group): derive grpc consumer FQN from java imports so client-jar consumers don't fall back to short names
Java gRPC microservices commonly follow the "client-jar" pattern: the
service owner publishes a pre-compiled stub jar to a Maven repository
and consumer repos depend on the jar instead of carrying the
originating `.proto` files. gRPC's official Java quickstart, Alibaba
HSF, ByteDance KiteX-Java and google-cloud-java all document this
shape.
Before this commit, `GrpcExtractor` resolved a fully-qualified
contract id (`grpc::<package>.<Service>/*`) only when the consumer
repo also carried a matching `.proto`. Client-jar consumers had no
proto, so they fell back to a short-name contract id
(`grpc::<Service>/*`) that never matched the provider's contract id.
Cross-repo grpc cross-link counts dropped to zero on every realistic
Java microservice group — including all of crsdp's `crsdp-backend →
unipus_cloud_framework` connections.
Fix: derive the proto package directly from each consumer file's
`import <pkg>.<XxxGrpc>;` statement. The package from the import is
exactly the proto package, so the contract id matches the provider's
verbatim — no `.proto` lookup needed in the consumer repo.
Implementation
--------------
* `grpc-patterns/types.ts` — `GrpcDetection` gains an optional
`protoPackage` field. Plugins set it when the package can be
derived from the source file alone.
* `grpc-patterns/java.ts` — adds `GRPC_CLASS_IMPORT_PATTERNS`, a
tree-sitter query that captures every
`import_declaration > scoped_identifier { scope, name }` pair where
the imported name ends in `Grpc`. `import static …` and
`import w.x.*;` are excluded by tree-sitter shape: the `name:` field
is only present on the non-static, non-wildcard form. The plugin
builds a per-file `XxxGrpc → fullPackage` map and tags every
provider / consumer detection it emits.
* `grpc-extractor.ts` — `detectionToContract()` now resolves the
contract id in three steps:
1. detection-supplied `protoPackage` wins (skips the proto map
entirely so an unrelated same-name service in the consumer
repo can't blur the FQN);
2. otherwise consult the legacy per-repo proto map;
3. otherwise fall back to a short-name contract id, preserving
pre-fix behaviour.
Confidence stays at the "with proto" tier when the import path
resolves: an import statement in real source is at least as
authoritative as a per-repo proto map.
Same-short-name disambiguation
-------------------------------
The motivating case `unipus_cloud_framework` defines two distinct
`ContentRpcService` services in different proto packages
(`cn.unipus.ucf.api.proto.client.service.ContentRpcService` vs
`cn.unipus.ucf.admin.proto.client.service.ContentRpcService`). Two
consumer files importing the two flavours now emit two distinct FQNs;
neither could be told apart from the other under the legacy short-
name fallback.
Out of scope
------------
`import w.x.*;` (wildcard service imports) are left to the legacy
short-name fallback. Wildcard imports are discouraged by Google's
Java style guide and IntelliJ's defaults, and resolving them
unambiguously would require either group-level proto-package
catalogs or per-class disambiguation, both of which are larger
follow-ups. This commit only changes behaviour for the dominant
specific-import case.
Tests
-----
`test/unit/group/grpc-extractor.test.ts` adds a new "Java client-jar
consumer (import-derived FQN)" describe block with 9 cases covering
both the happy paths (consumer/provider FQN derivation, same-short-
name disambiguation, import-vs-local-proto precedence) and the
regression-protection paths (no import + no detection emitted, static
imports / wildcards ignored, mixed-file repos preserved).
End-to-end verification
-----------------------
Ran the patched cli on the real `crsdp-backend` (consumer, no
`.proto`) and `unipus_cloud_framework` (provider, has `.proto`)
repos. Synced as a two-repo group, every `XxxGrpc` referenced via a
specific import in `UcfAdminGrpcClientService.java` produced an FQN
contract id that exact-matched the provider repo's FQN — 9 grpc
cross-links surfaced where there were 0 before.
Verification
------------
* `npx tsc --noEmit`: pass
* `npx tsc` (dist rebuild): pass
* `test/unit/group/grpc-extractor.test.ts`: 60/60 pass (51 existing
+ 9 new)
* `test/unit/group/`: 30 files / 545 tests all green
* `npx prettier --check` on touched files: pass
* `npx eslint` on touched src files: 0 errors / 0 warnings
* fix(group): handle option java_package and proto-map disagreement in grpc detection
Addresses Claude bot review on PR #1889:
- Finding 1: parse `option java_package` when building proto context;
add a reverse index so an import-derived package can be translated
back to the proto package.
- Finding 2: when same-repo proto map has the service, use the proto
package; warn and record `meta.importPackage` if the import disagrees.
- Finding 3: add an end-to-end wildcard match test (provider+consumer
fixture, runs `buildProviderIndex`+`runWildcardMatch`).
Client-jar consumer + diverging `java_package` (no local proto)
remains a known limitation; pinned by a dedicated test.

* feat(cobol): migrate COBOL to scope-based resolution (regex provider)
Migrate COBOL to scope-based registry resolution, validating the
parse-source-agnostic contract — COBOL uses regex, not tree-sitter,
but implements the same LanguageProvider interface via emitScopeCaptures.
Phase 1-5 complete per #941 DoD.
New files:
languages/cobol/captures.ts — emitScopeCaptures wrapping regex tagger
languages/cobol/interpret.ts — import/type-binding/receiver hooks
languages/cobol/index.ts — barrel export
languages/cobol/scope-resolver.ts — ScopeResolver wiring (9 fields, 3 toggles)
Modified files:
languages/cobol.ts — wire 4 scope-resolution hooks
registry.ts — register cobolScopeResolver
registry-primary-flag.ts — document REGISTRY_PRIMARY_COBOL
Fixtures:
17 fixture files, 30 test cases across 11 required classes
test/integration/resolvers/cobol-scope.test.ts
Tests: 24/24 pass (default + REGISTRY_PRIMARY_COBOL=0)
tsc: zero cobol-specific errors
Shadow mode (GITNEXUS_SHADOW_MODE=1): zero crashes
Regex perf: 10K-line file in 408ms (threshold: 2000ms)
NOT added to MIGRATED_LANGUAGES — REGISTRY_PRIMARY_COBOL env var only.
* chore(cobol): add COBOL to MIGRATED_LANGUAGES
* fix(cobol): revert MIGRATED_LANGUAGES flip, fix JSDoc dup, fix arityCompatibility
* fix(standalone): wire standalone providers into scope-extractor for registry-primary (COBOL Ring 3 flip)
- Gate cobolPhase with isRegistryPrimary() guard to prevent double emission
- Wire standalone providers (parseStrategy !== 'tree-sitter') with
emitScopeCaptures into parse-worker via extractParsedFile bridge
- Add COBOL to MIGRATED_LANGUAGES in registry-primary-flag.ts
- Fix Module scope range in captures.ts to use full program bounds
(was just PROGRAM-ID line, causing scope containment failures)
- Update cobol.test.ts grand totals to be mode-aware
- Wrap legacy exact-count assertions in if (!isPrimary)
- Fix cobol-scope.test.ts fixture path to use __dirname (was process.cwd())
Tests:
REGISTRY_PRIMARY_COBOL=0: 83/83 pass (59 legacy + 24 capture)
REGISTRY_PRIMARY_COBOL=1: 28/28 pass (4 mode-aware + 24 capture)
* test(cobol): restore original test assertions, add mode-aware describe blocks alongside
- Remove if (!isPrimary) wrapper from legacy assertions
- Keep ALL 59 original tests intact and running unconditionally
- Add new 'scope-resolution mode' describe block alongside legacy tests
- New block uses isPrimary to check for scope-resolution capture output
- Legacy tests run against cobolPhase output (skipGraphPhases=true)
- Mode-aware tests validate standalone provider wiring in registry-primary mode
* fix(test): use result.graph instead of result.parsedFiles in scope-mode test
- PipelineResult has no parsedFiles field; use graph.nodes instead
- Use toBe strict equality (not.toBeNull()) per review feedback
- Object.keys for node count as suggested by reviewer
* test(cobol): add COBOL pipeline benchmark following PHP benchmark structure
- Generate synthetic COBOL codebases at 100/250/500 file scales
- Each file has 1 PROGRAM-ID, N paragraphs, cross-file CALLs, COPY books
- Measures wall-clock time, peak heap, node/edge counts
- SkipIf(!GITNEXUS_BENCH) — run with GITNEXUS_BENCH=1
- Prints table with scaling ratios and linearity assertions
* fix(bench): remove COPY from paragraphs, add REGISTRY_PRIMARY_COBOL note
- COPY statements belong only in DATA DIVISION (already present there)
- Revert copyLine inside paragraph blocks to idiomatic COBOL
- Add header note about =1 mode producing ~0 node/edge counts
* fix(bench): restore COPY in paragraphs for preprocessing stress
- COPY in paragraph blocks exercises the preprocessor expansion path
more heavily than DATA DIVISION only placement.
* fix(bench): constant 3 paragraphs per program, add 1000-files scale, relax threshold to 4x
- Fixed paragraphsPerProgram to constant 3 for consistent scaling
- Added 1000-file scale to benchmark
- Raised assertion threshold to 4x to accommodate 100-250 step
* fix: skip standalone providers in scope-resolution phase when registry-primary
scopeResolutionPhase was reading all COBOL files from disk and running
scope-resolution for standalone providers that don't emit graph edges
yet. Added a guard: if provider.languageProvider.parseStrategy ===
'standalone', skip it entirely. Saves 68s at 1000 files in =1 mode.
* fix: remove COBOL isRegistryPrimary gate, suppress standalone IMPORTS double-emission
- Remove the isRegistryPrimary gate in cobolPhase so it runs in both modes,
keeping cobolPhase as the sole COBOL graph-edge producer.
- Add a guard in runScopeResolution to skip emitImportEdges for standalone
providers (parseStrategy === 'standalone'), preventing scope-resolution
from duplicating IMPORTS edges already produced by cobolPhase.
- Scope-resolution still runs for standalone providers (capture extraction,
model finalization, reference resolution) — only edge emission is skipped.
- Both modes: 60/60 cobol.test.ts, 24/24 cobol-scope.test.ts.
* fix: 4 review fixes — dead code removal, memory cleanup, benchmark comment, standalone-bridge test
1. Remove dead standalone guard in run.ts (phase.ts:164 is canonical).
2. Filter standalone preExtractedByPath entries in phase.ts (memory leak).
3. Update benchmark comment: cobolPhase runs in both modes.
4. Add unit test proving extractParsedFile works for COBOL standalone provider.
Revert PipelineResult.parsedFiles — not needed with unit test approach.
* perf(cobol): memoize copybook preprocessing; make benchmark measure file-count scaling
The COBOL pipeline benchmark reported superlinear (quadratic) scaling, but the
pipeline itself is O(n) in file count. The superlinearity was a fixture artifact:
every program COPYed all floor(fileCount/5) copybooks in WORKING-STORAGE, so
emitted data-item nodes — and total work — grew O(n^2). Verified empirically:
node count grew ~2x per file-doubling; with constant per-program fan-out it grows
exactly 1x (linear), and 0/3 adversarial audits could refute the O(n) conclusion.
- benchmark: each program now COPYs a constant 3 shared copybooks so the
benchmark measures true file-count scaling. Add a deterministic node-ratio
assertion that fails if the O(n^2) copy-all fan-out is reintroduced.
- processor: memoize preprocessed copybook content per processCobol call so each
copybook is preprocessed once, not once per COPY site
(O(programs x copybooks) -> O(copybooks)). Safe: REPLACING is applied later by
the expander on the cached pre-REPLACING content.
Verified: 246 COBOL tests pass; benchmark scales linearly (node ratio 1.0); tsc clean.

* feat(group): add Kotlin Spring WebClient long-form HTTP consumer extraction
Follow-up to #1855. Extends `kotlin.ts` with the long-form WebClient
fluent chain that #1855 explicitly deferred:
webClient.method(HttpMethod.GET).uri("/x").retrieve().awaitBody<T>()
This pattern remains common in Kotlin Spring 4 → 5 migrations and in
codebases that prefer the fluent verb-as-enum style. The short form
(`webClient.get().uri("/x")`) was already supported in #1855.
Approach:
- Single deeper tree-sitter query (`WEB_CLIENT_LONG_PATTERNS`) that
matches the full chain structurally — both `.method(HttpMethod.X)`
and `.uri("...")` in one pattern. Verb is captured as the
`simple_identifier` of the `HttpMethod.X` field access.
- Verb is whitelisted to GET/POST/PUT/DELETE/PATCH (consistent with
the short-form's `WEB_CLIENT_SHORT_TO_HTTP` map).
- Receiver constraint `(#eq? @obj "webClient")` mirrors the short
form and Java plugin heuristic.
Out of scope (intentional):
- Variable-bound verbs: `val verb = HttpMethod.PATCH; webClient.method(verb)...`
Source-scan can't follow the binding without graph context.
Pinned by an anti-overreach test.
- HEAD/OPTIONS/TRACE: not in `WEB_CLIENT_SHORT_TO_HTTP` either —
keeps polyglot symmetry with java.ts and the short form.
Tests: 4 new cases under `consumer extraction — fetch patterns`,
gated by tree-sitter-kotlin grammar availability.
positive (3)
- long form GET
- long form POST / PUT / DELETE / PATCH (4 verbs in 1 fixture)
- no double-emit pin (long-form chain produces exactly one
consumer, not one from each query)
anti-regression (1)
- variable-bound verb does NOT match (graph-aware concern)
The previous `'does NOT match Kotlin WebClient long form (deferred
to follow-up)'` test from #1855 is replaced by these — the deferred
state is now resolved.
Reverse-validated: temporarily disabling the long-form emit makes
exactly the 3 positive tests fail; the variable-bound-verb anti-
regression test continues to pass (it pins behavior independent
of the emit being on or off).

* test(group): address Claude review findings F1 and F2 on PR #1884
Two minor follow-ups from the production-readiness review:
F1 — Stale block comment at the top of the Kotlin consumer suite
(was: "Three consumer flavors covered here ... long-form deferred
to a follow-up"). Updated to "Four consumer flavors" and removed
the deferred sentence — the deferral is resolved by this PR. The
kotlin.ts file header was already updated; this brings the test
file comment in sync. Per DoD §2.3 (no stale comments).
F2 — Replaced `expect(wcConsumers.length).toBeGreaterThanOrEqual(4)`
with `expect(wcConsumers).toHaveLength(4)` in the multi-verb test.
The fixture is fully deterministic — exactly 4 long-form calls,
no other consumer types — so an exact count assertion is the right
shape per DoD §2.7 ("use toBe / toEqual for exact expectations").
Added a comment explaining what the assertion catches that the
existing per-verb toBeDefined() checks would miss (accidental 5th
consumer from a duplicate query firing or a regressed receiver
constraint).
F3 (HEAD/OPTIONS/TRACE negative test) is intentionally not added
in this PR — same precedent as #1855 where HEAD/OPTIONS/TRACE on
the short form are also implicitly excluded without a pinning
test. Happy to add one in a separate PR if maintainers want
explicit pinning across both forms.
F4 (CI on pre-merge SHA) is the maintainer's call — the merge from
main is theirs to re-trigger CI on. The merge brings only Java
consumer changes (PR #1872) and Go provider changes (PR #1886),
both in entirely separate files from this PR's Kotlin work.
Local validation:
- test/unit/group/http-route-extractor.test.ts: 73/73 ✅
(66 from this PR pre-merge + 7 from PR #1872 merged via main)

* refactor(group): hoist Kotlin WebClient long-form verb regex to module scope
Address @magyargergo's review request on PR #1884:
> Can you please extract the regexp from the for loop? 🙏
(kotlin.ts:510)
Compiles the verb whitelist `^(GET|POST|PUT|DELETE|PATCH)$` once at
module load instead of every iteration of the long-form scan loop.
Mirrors the placement and JSDoc style of the sibling
`WEB_CLIENT_SHORT_TO_HTTP` constant.
Behavior is unchanged — same verb whitelist, same exclusion of
HEAD/OPTIONS/TRACE for symmetry with the short form. The 4
itKotlinConsumer long-form tests added in this PR continue to
pass, and the variable-bound-verb anti-overreach test continues
to pin the deliberate non-match.

* feat(ingestion): resolve FastAPI include_router(prefix=...) cross-file routes
FastAPI sub-route files declare paths via @router.<verb> while the entry
file mounts the router with app.include_router(<router>, prefix='/x').
Previously both the ingestion-layer Route graph nodes and the group-layer
ExtractedContract URLs lost the cross-file prefix, breaking provider <->
consumer matching.
Ingestion layer:
- parse-worker emits routerIncludes / routerImports + decoratorReceiver
- parsing-processor / parse-impl thread the new fields and aggregate
prefixesByModule across chunks; decorator routes whose receiver is
'router' are duplicated once per matching prefix
- routes.ts joins prefix via normalizeExtractedRoutePath
Group layer:
- HttpLanguagePlugin gains an optional prepareRepo() pre-pass and a
repoContext arg to scan(); python.ts builds prefixesByModule and
falls back to the bare path when no entry matches
- http-route-extractor caches one repoContext per plugin
Tests:
- 3 new http-route-extractor cases (attr / named-import / no-prefix)
- ParseWorkerResult literals in 3 test files updated to the new shape
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(ingestion,group): address PR #1877 review — relative imports, cross-package collisions, host names, ingestion tests
Follow-ups to the FastAPI `include_router(prefix=...)` cross-file fix
based on PR #1877's automated production-readiness review. Three
correctness gaps and one test coverage gap addressed:
1. Relative-import support in the worker regex (FINDING 2)
`FROM_IMPORT_ROUTER_RE` now accepts module paths starting with a
`.` (e.g. `from .calls import router as calls_router`). The
previous `[A-Za-z_][\w.]*` rejected leading dots and silently
dropped every relative-import Shape-B include — a real pattern
from the PR description's own motivating example. The matching
helpers now strip leading dots before keying so absolute and
relative imports collapse to the same module key.
2. Cross-package same-name module collisions (FINDING 3)
Two-tier module keying replaces the previous basename-only key:
• short key — `users` (file basename without `.py`)
• long key — `api/users` (parent dir + stem)
`prefixesByLongKey` is consulted first and only falls back to
`prefixesByShortKey` when no long-key match is available. Both
the ingestion pipeline (parse-impl.ts) and the group extractor
(http-patterns/python.ts) carry the same scheme so the graph
nodes and HTTP contracts agree on which prefix applies.
New protocol field `ExtractedRouterModuleAlias` (parse-worker →
parsing-processor → parse-impl) lets Shape-A
`<host>.include_router(<mod>.router, prefix='/x')` calls promote
to a long key when the same file imports `<mod>` via
`from <pkg> import <mod>`. Without this, `api/users.py` and
`admin/users.py` collided on the basename `users` and the admin
file's routes inherited the `/users` prefix that was only meant
for `api/users.py`.
3. Non-`app` host variable names (FINDING 4)
The group-layer `INCLUDE_ROUTER_*_PATTERNS` queries pinned the
host identifier to the literal `"app"` and dropped every
`application = FastAPI()` / `api = FastAPI()` pattern — the
constraint was redundant given that the call shape
(`include_router` invoked with a router argument and a
`prefix=` keyword) is already specific enough. The pin is
removed; the ingestion regex was already unrestricted.
4. Ingestion-layer regression tests (FINDING 1)
The previous PR added group-layer tests
(`http-route-extractor.test.ts`) but zero in-tree tests for the
ingestion path. Two new suites pin the
worker → parse-impl → routes flow:
- `test/unit/fastapi-router-bindings.test.ts` (23 cases):
`extractFastAPIRouterBindings()` is split into a stand-alone
module so it can be unit-tested without booting a worker
thread, then pinned for regex shape, two-tier key emission,
relative-import support, and negative cases.
- `test/integration/fastapi-prefix-pipeline.test.ts` (5 cases)
plus `test/fixtures/fastapi-prefix-app/` — runs the full
`runPipelineFromRepo()` against a realistic multi-package
fixture (containing both `api/users.py` and `admin/users.py`)
and inspects the resulting `Route` graph nodes for cross-file
prefix joining and absence of cross-package bleed.
Verification
- `npx tsc --noEmit`: pass
- PR-touched test suites (6 files / 117 cases): all green
- `npx prettier --check`: pass on touched files
- `npx eslint`: 0 errors on touched files
Cache / compatibility
The new `routerModuleAliases?` field on `ParseWorkerResult` and
`routerModuleAliases` on `WorkerExtractedData` are optional /
guarded with `?? []`, so historical parse-cache entries continue
to load without forced re-scan.

* refactor(ingestion): move fastapi-router-bindings out of workers/ — pure module, not a worker
Addresses @magyargergo's `CHANGES_REQUESTED` review on PR #1877:
> Sorry I just found that we are introducing a new worker in the PR.
`gitnexus/src/core/ingestion/workers/fastapi-router-bindings.ts` was a
**pure-function module** — it never imported `worker_threads` or
`parentPort`, never spawned a worker, and was never registered as a
worker entry. It was placed in `workers/` purely because it was split
out of `workers/parse-worker.ts` to make its functions unit-testable
without booting a worker thread (parse-worker is itself the worker
entry and cannot be loaded from the main thread).
To remove the misleading directory placement:
• The implementation moves to
`gitnexus/src/core/ingestion/route-extractors/fastapi-router-bindings.ts`,
alongside the other framework-specific route extractors (`expo`,
`nextjs`, `php`, `laravel`, `middleware`, `response-shapes`).
• `workers/parse-worker.ts` keeps a thin re-export so the worker
entry can keep using `extractFastAPIRouterBindings` directly. The
re-export now carries an explicit comment stating that the imported
file is **not** a worker and that the `workers/` directory
deliberately hosts only true worker entries (`parse-worker.ts`,
`worker-pool.ts`, `quarantine.ts`).
• The new file's leading docstring opens with "NOT A WORKER" and
explains why it exists where it does.
• The unit test (`test/unit/fastapi-router-bindings.test.ts`) is
updated to import from the new path.
No behaviour change. The function body, signatures, and exported types
are identical.
Verification
• `npx tsc --noEmit`: pass
• `npx tsc` (dist rebuild): pass
• `test/unit/fastapi-router-bindings.test.ts` (23 cases): all green
• `test/integration/fastapi-prefix-pipeline.test.ts` (5 cases): all green

* refactor(ingestion): drop parse-worker re-exports; consumers import router types directly from route-extractors
Addresses @magyargergo's two remaining review comments on PR #1877:
1. **`gitnexus/src/core/ingestion/workers/parse-worker.ts:247`** —
"Can you please remove them and update the call sites?"
The `export type { ExtractedRouterInclude, ExtractedRouterImport,
ExtractedRouterModuleAlias } from '../route-extractors/...'` block
in parse-worker.ts is gone. The remaining `import type {…}` is
purely local — used only to type the corresponding fields on
`ParseWorkerResult` below — and the leading comment now says so
explicitly ("this file does NOT re-export them"). The
`extractFastAPIRouterBindings` symbol is also no longer re-exported
from parse-worker.ts; it's still imported here so the worker entry
can call it per file, but downstream consumers must reach it via
`route-extractors/fastapi-router-bindings` directly.
Call sites updated:
- `gitnexus/src/core/ingestion/parsing-processor.ts`
- `gitnexus/src/core/ingestion/pipeline-phases/parse-impl.ts`
Both files now `import type { ExtractedRouterInclude,
ExtractedRouterImport, ExtractedRouterModuleAlias }` directly from
`route-extractors/fastapi-router-bindings.js`. The worker types
they still need (`ParseWorkerResult`, `ExtractedToolDef`, etc.)
keep coming from `workers/parse-worker.js`.
The unit + integration tests already imported from the new path,
so no test changes were required.
2. **`gitnexus/src/core/ingestion/parsing-processor.ts:168`** —
suggested simplification:
for (const item of result.routerIncludes ?? []) allRouterIncludes.push(item);
for (const item of result.routerImports ?? []) allRouterImports.push(item);
for (const item of result.routerModuleAliases ?? []) allRouterModuleAliases.push(item);
Applied verbatim. Replaces the previous `if (result.…) for …`
guards. The cache-compat semantics are unchanged — historical
parse-cache entries that lack these fields still load cleanly,
the new form just spells the fallback inline.
No behavior change, no tests touched, no public API change.
Verification
• `npx tsc --noEmit`: pass
• `npx tsc` (dist rebuild): pass
• PR-touched test suites (6 files / 117 cases): all green
• `npx prettier --check` on touched files: pass
• `npx eslint` on touched files: 0 errors
Refs PR #1877.
* refactor(ingestion): hoist fastapi-router-bindings type imports to top of parse-worker.ts
Move the `import type { ExtractedRouterInclude, ExtractedRouterImport,
ExtractedRouterModuleAlias }` block to the top of the file with the
other type imports, and drop the comment that previously sat next to
ExtractedDecoratorRoute.

* feat(impact): per-symbol processes field on byDepth items
Today `impact` returns aggregated `affected_processes` at the top level
but the per-symbol `byDepth` items don't say which processes each caller
participates in. Consumers planning a deploy want to know if a given
caller is hit by a daily cron, a webhook, or a user-facing route - each
is a different deploy-risk profile - and that information requires a
follow-up cypher query per symbol today.
This change attaches `processes: [...]` to every `byDepth[depth][i]`
item, listing the processes that symbol participates in:
byDepth: {
"1": [
{
depth: 1,
id: "Function:src/foo.ts:doStuff",
name: "doStuff",
...
processes: [
{ id: "proc:cron_daily", label: "Daily cron",
processType: "cron", step: 12 }
]
}
]
}
The list is empty for symbols not in any process. Additive change, no
breaking modifications to existing fields.
Implementation:
- A second chunked Cypher pass runs after the existing per-process
aggregation pass, returning per-(symbol, process) rows. Same chunk
size and MAX_CHUNKS as the aggregation pass, so worst-case adds 10
extra round-trips bounded by the same env var.
- The enrichment pass is skipped entirely when `affectedProcesses.length
=== 0` (nothing to enrich) or `summaryOnly === true` (byDepth not
returned anyway).
- The aggregation query is unchanged - the new query has a distinct
RETURN shape (`RETURN s.id AS sid, ...`) so an existing unit test that
counts STEP_IN_PROCESS chunks was narrowed to match only the
aggregation pattern.
Tests:
- New: byDepth items always have a `processes` field (default empty
when no STEP_IN_PROCESS edges exist).
- New: when STEP_IN_PROCESS rows exist, the matching byDepth item
carries the right `{id, label, processType, step}` entry.
- Updated: impact-batching-grouping test mock narrowed to count only
aggregation chunks (the new per-symbol pass is covered separately).
* style: apply prettier to gitnexus/src/mcp/local/local-backend.ts
Pure line-wrap fix flagged by quality / format CI on PR #1867. Zero
semantic change: prettier broke a chained .slice().map() across three
lines instead of one. No test changes, no logic changes.
* fix(impact): address PR review findings on per-symbol process enrichment
- byDepth.processes doc now states each item carries processes (Finding 1)
- move per-symbol STEP_IN_PROCESS enrichment post-pagination so symbols
beyond the pre-pagination cap no longer get false-empty processes:[]
(Finding 2); hoist CHUNK_SIZE/MAX_CHUNKS to function scope so the
post-pagination pass can reference them
- dedup per-symbol query with DISTINCT + MIN(r.step) per (symbol,process)
pair (Finding 3)
- suppress the per-symbol pass under summaryOnly, incl. impactByUid group
fan-out, plus a test asserting the query never fires (Findings 4, 6)
* fix(impact): address second-round review findings A-E
Finding A (blocker): impactByUid passed summaryOnly:true, which drops the
entire byDepth field. cross-impact.ts reads fan.byDepth to build the group
by_depth output, so cross-repo by_depth was always {}. Replace with a new
skipPerSymbolEnrichment option on _runImpactBFS that suppresses only the
per-symbol STEP_IN_PROCESS pass while preserving byDepth.
Finding B+D (blocker): rewrite the byDepth.processes tool description. Drop
the stale "enrichment cap" wording (no longer true post-pagination), document
the {id,label,processType,step} entry shape, and tell agents to cross-check
affected_processes when partial:true.
Finding C: bound the post-pagination per-symbol enrichment loop to
MAX_CHUNKS*CHUNK_SIZE page IDs and surface partial:true when capped, so a
large page cannot trigger unbounded DB round-trips (DoD 2.6).
Finding E: add a test exercising the real impactByUid -> _runImpactBFS path
asserting byDepth survives and the per-symbol query never fires.

* feat(group): add Kotlin Spring HTTP consumer extraction
Follow-up to #1849 (Kotlin providers). Extends `http-patterns/kotlin.ts`
with three call-site patterns common in Kotlin Spring projects:
- RestTemplate: `restTemplate.getForObject("/x", ...)` and the
full verb family (getForObject/getForEntity → GET,
postForObject/postForEntity → POST, put → PUT, delete → DELETE,
patchForObject → PATCH). Mirrors the Java plugin's
`REST_TEMPLATE_TO_HTTP` map so polyglot repos coalesce on a
single contract id.
- WebClient short form: `webClient.get().uri("/x")` and the
`.post()` / `.put()` / `.delete()` / `.patch()` siblings. The
chain parses as two nested `call_expression` nodes; the query
anchors on the outer `.uri(...)` and walks one level inward
to constrain the verb.
- OkHttp: `Request.Builder().url("/x")`. Kotlin parses
`Request.Builder()` as a `call_expression` whose callee is a
`navigation_expression` (not Java's `object_creation_expression`),
so the query shape differs from `java.ts` but the receiver/method
constraints (`Request` / `Builder` / `url`) and emitted
contract format match.
Out of scope: `webClient.method(HttpMethod.X).uri("/y")` long form.
The verb sits on a sibling `call_expression` two hops away, so it
needs a walk-up helper rather than a flat tree-sitter query. A
dedicated anti-overreach test pins the current behavior so a future
short-form change can't accidentally start matching the long form.
Receiver name constraints (`#eq? @obj "restTemplate"`,
`#eq? @cls "Request"`) match the Java plugin's heuristic — a project
that aliases the receiver under a different name won't be picked up.
This trade-off keeps false-positive rates low and is documented in
the file header.
Tests: 5 new cases under `consumer extraction — fetch patterns`,
gated by tree-sitter-kotlin grammar availability.
positive (3)
- RestTemplate verbs (5 calls × 5 verbs)
- WebClient short-form verbs (5 calls × 5 verbs)
- OkHttp Request.Builder().url("/x")
anti-regression (2)
- WebClient long form `.method(HttpMethod.X)` produces no
consumer (deferred-feature pin)
- non-restTemplate receiver does not match (receiver-name pin)
Reverse-validated: removing the `(#eq? @obj "restTemplate")`
constraint causes the receiver-name anti-regression test to fail.
Local validation:
- test/unit/group/http-route-extractor.test.ts: 59/59 ✅
- test/unit/group: 539/539 ✅
- npm run format:check: clean ✅
* test(group): pin Kotlin OkHttp POST-chain heuristic-default GET behavior
Address Claude review on PR #1855 (Finding 1).
The OkHttp query in `kotlin.ts:OK_HTTP_PATTERNS` matches the
`.url("/x")` sub-expression of a builder chain, but the verb is
encoded on a separate sibling call (`.post(body)` / `.delete()` /
...). The query intentionally does not walk the chain to recover
the verb — it emits `method: 'GET'` for every match, mirroring the
Java plugin's `OK_HTTP_PATTERNS` (java.ts).
Concretely: `Request.Builder().url("/x").post(body).build()` becomes
`http::GET::/x`, not `http::POST::/x`. This is an already-accepted
Java parity heuristic, but it was untested on the Kotlin side.
This commit:
- Adds an anti-overreach test pinning the current behavior:
* exactly one consumer is emitted with method=GET
* no second http::POST::/x consumer appears
- Documents the limitation in kotlin.ts as a "Known limitation"
block tied to the test, so a future verb-walk implementation
has to update the comment in lockstep with the assertion.
Rationale for not implementing verb-walk in this PR:
- Verb-walk requires walking sibling call_expression nodes (the
`.post(body)` chain), which is the same shape as the
deferred WebClient long-form work
- Java has the same limitation in production today; fixing only
Kotlin would create polyglot drift
- A coordinated future PR can add verb-walk to both plugins at
once and update both comments + the pin tests together
Finding 2 (silent test-skip when tree-sitter-kotlin grammar is
unavailable) is intentionally NOT addressed here — same gating
pattern was accepted in #1849 for Provider tests, and a coordinated
follow-up should add a CI sentinel covering both Provider and
Consumer suites in one place.

* feat(group): add Kotlin Spring HTTP route extraction (named + positional)
Mirror the Java Spring named-argument fix for Kotlin Spring Boot
controllers. Adds a new `http-patterns/kotlin.ts` plugin behind the
optional `tree-sitter-kotlin` grammar, registered for `.kt`/`.kts`.
Both annotation forms produce providers:
@RequestMapping("/api") / @GetMapping("/users")
@RequestMapping(path = "/api") / @GetMapping(value = "/users")
@RequestMapping(value = "/api") / @GetMapping(path = "/users")
The Kotlin AST (fwcd/tree-sitter-kotlin) shares one node type
(`value_argument`) for positional and named forms, so the queries
are split:
- positional: anchors `string_literal` as the first named child
of `value_argument` via the immediate-child anchor `.`
- named: explicitly captures `simple_identifier` and constrains
it to `^(path|value)$` via `#match?`, mirroring the same
safety bar enforced by `http-patterns/java.ts` and
`topic-patterns/java.ts`. Without this constraint the query
would also capture non-route attributes like `produces`,
`consumes`, `headers`, `name`, `params`.
`tree-sitter-kotlin` is an optionalDependency (parser-loader.ts,
parse-worker.ts pattern). When the native binding is unavailable
the plugin exports `null` and `index.ts` skips registering
`.kt`/`.kts` so the orchestrator stays healthy.
Scope: providers only. Consumer detection (RestTemplate, WebClient,
OkHttp) on Kotlin call-site ASTs differs enough from Java's
`method_invocation` shape to warrant a separate, focused PR.
Tests: 11 new cases under `provider extraction — source-scan
fallback (Strategy B)`, gated by the kotlin grammar availability.
positive (8)
- class @RequestMapping("/api/v1") (positional)
- class @RequestMapping(path = "/api/v2")
- class @RequestMapping(value = "/orders")
- method @GetMapping(value = "/users")
- method @GetMapping(path = "/users")
- method @PostMapping(path = "/users")
- mixed: class named-arg + method positional
- mixed: class positional + method named-arg
anti-regression (3)
- @GetMapping(produces = "application/json") emits no provider
- @GetMapping(name = "x", value = "/users") emits exactly one provider
- @RequestMapping(path = "/api", name = "myApi") prefix stays /api
Reverse-validated: removing the `(#match? @key "^(path|value)$")`
constraint causes precisely the 3 anti-regression tests to fail.
Local validation:
- test/unit/group/http-route-extractor.test.ts: 54/54
- test/unit/group: 534/534
- npx tsc --noEmit: clean (modulo the pre-existing TS2339 in

* fix(group): handle named annotation args in Java Spring route extraction
The Java HTTP plugin only matched positional `@RequestMapping("/path")`
syntax for class-level prefixes and method-level routes. Named argument
forms (`path = "/path"` and `value = "/path"`) produce an
`element_value_pair` AST node that the tree-sitter queries did not cover,
causing the class prefix to be lost and named-arg method routes to be
missed entirely during cross-repo contract extraction.
Add a second pattern to both SPRING_CLASS_PREFIX_PATTERNS and
SPRING_METHOD_ROUTE_PATTERNS matching the element_value_pair structure.
* fix(group): constrain Spring named-arg query to path/value keys + add regression tests
Address Claude review on PR #1834. The named-argument patterns added
in 8b6fa6e used `value: (string_literal)` (a tree-sitter field
selector for the right-hand side of element_value_pair), which matched
ANY annotation member with a string value — not just `path`/`value`.
Concrete fallout (without this fix):
@GetMapping(produces = "application/json") → bogus http::GET::/application/json
@GetMapping(name = "listUsers", value = "/users") → extra http::GET::/listUsers
@RequestMapping(headers = "X-Foo=bar", path = "/api") → class prefix
could be set to "X-Foo=bar" because prefixByClassId.set runs per
match in document order, so the LAST element_value_pair wins.
The sibling topic-patterns/java.ts already demonstrates the correct
shape: constrain the `key:` field to the route member names.
This commit:
- Adds `key: (identifier) @key (#match? @key "^(path|value)$")` to
both SPRING_CLASS_PREFIX_PATTERNS and SPRING_METHOD_ROUTE_PATTERNS
named-arg queries.
- Adds 9 regression tests under
`provider extraction — source-scan fallback (Strategy B)`:
* @RequestMapping(path = "/api/v3") class prefix
* @RequestMapping(value = "/orders") class prefix
* @GetMapping(value = "/users") method route
* @PostMapping(path = "/users") method route
* mixed: class named-arg + method positional
* mixed: class positional + method named-arg
* @GetMapping(produces = "application/json") → no provider emitted
* @GetMapping(name = "listUsers", value = "/users") → exactly one
provider with path "/users", no /listUsers route
* @RequestMapping(path = "/api", name = "myApi") → prefix is /api,
not myApi (verifies the class-prefix overwrite scenario)
Tests: 42/42 pass in http-route-extractor.test.ts;
522/522 pass under test/unit/group;
npx tsc --noEmit clean.
* test(group): add @GetMapping(path = ...) case to match review checklist verbatim
Claude review on PR #1834 explicitly asked for the method-level
`@GetMapping(path = "/users")` case. The previous commit covered it
indirectly by exercising path= on @PostMapping (the Spring method
annotations share the same query, so any verb proves the path= field
is matched). Add a dedicated GET+path= test so the reviewer's
checklist is satisfied 1:1, and keep the POST+path= case as a bonus
verb-coverage test.
Tests: 43/43 pass in http-route-extractor.test.ts.

* fix(web): cap tree layout spring iterations and remove unused variable
Finding A (blocker): calculateTreeLayout runs 14 synchronous spring
iterations over all edges and nodes — O(N×E×14) + O(N log N) per layer
per iteration — with no size guard. At 10K+ nodes this freezes the
main thread for several seconds.
Fix: make SPRING_ITERATIONS adaptive:
- N > 10 000 → 0 iterations (proportional initial layout only)
- N > 3 000 → 4 iterations
- otherwise → 14 iterations (unchanged behaviour for small graphs)
Also removes the unused `const r` at useSigma.ts:1314, which was a
leftover after the radial-resistance decomposition was removed.
This clears the CodeQL "unused variable" warning (Finding G).

- edge styling: CONTAINS is marked isHierarchyEdge=true with the
hierarchy colour; CALLS is cross-cutting with its own colour.
- CALLS cross-cutting: a lone CALLS edge between two Functions is
correctly identified as a non-hierarchy edge.
Also adds a performance-bound test for the tree adapter at 2 000 nodes /
4 000 edges (the adaptive 14-iteration path) asserting completion within
2 s — catches regressions to the O(N×E×iterations) main-thread blocking

* perf(web): add adaptive large-graph guards to sequential layout physics
For graphs with N > 5 000 nodes, each rAF frame of runTreeLayout was
doing O(N log N) sort + O(N × k) repulsion pair comparisons (k ≈ 2 400
for a 20 K-node graph spread across 1 080 px at range 130). At that
scale each frame took hundreds of ms, making the canvas appear completely
frozen even though the physics loop was still running.
Fix mirrors the circles layout adaptive strategy:
N > 5 000 (large):
- Skip repulsion pass (O(N × k) → 0)
- Skip spread-force sort (O(N log N) → 0)
- Velocity cap raised to ±12 / ±6 px so nodes cover ground faster
- Damping 0.58, 1 sim step/frame, 30 s max duration
- Looser early-stop thresholds (max v 0.05, avg v 0.03, active 2 %)
N > 1 500 (medium):
- Velocity cap raised to ±6 / ±3 px
- 24 s max duration
- Repulsion and spread still active
N ≤ 1 500 (small):
- Unchanged behaviour (velocity ±3/±2, 18 s, all forces active)
Layer gravity (O(N)) and edge springs (O(E)) run for all graph sizes —
they provide the structural pull that replaces repulsion at large N.

* fix(web): fix stale closure in sigma event handlers breaking node selection
The sigma 'clickNode', 'clickStage', 'enterNode', and 'leaveNode' handlers
are registered in a one-time useEffect (empty dep array). They captured
options.onNodeClick via closure, so they always called the initial version
of handleNodeClick — the one created before the graph loaded where
`if (!graph) return` exits immediately.
Consequence: clicking a node in the canvas never updated the app-level
selectedNode state. This broke:
- The Focus Depth filter (warning "Select a node to apply depth filter"
persisted even after a canvas click)
- The depth hop filter not applying (selectedNode was always null)
- The code panel not opening on canvas node click
Fix: store the three callback props in refs (onNodeClickRef, onNodeHoverRef,
onStageClickRef) and update them synchronously on every render. The sigma
event handlers now read from the refs, so they always invoke the latest
version of the callbacks without needing to re-register.

* fix(web): address three code-review bugs in graph rendering
Bug 1 (useSigma.ts): forces in the tree physics loop were computed once
before the sub-steps loop and reused for every step, causing 2× displacement
on slow frames (>64ms, simulationSteps>1). Fix: move forceX/forceY Maps and
all force accumulation (layer gravity, edge springs, repulsion, spread) inside
the loop so each sub-step integrates from current node positions.
Bug 2 (graph-adapter.ts): all three adapters used `graph.hasEdge(src,tgt)`
as a dedup guard, which silently drops any second edge between the same node
pair. A CALLS relationship between nodes that also have a CONTAINS edge was
always lost. Fix: switch from `new Graph()` to `new MultiGraph()` (allows
multiple edges per pair) and dedup by `rel.id` instead of by node pair.
Bug 3 (graph-adapter.test.ts): the cross-cutting edge styling test never
executed its CALLS branch because Bug 2 dropped the CALLS edge before the
assertion ran. Fix: assert `sigmaGraph.size === 2` and verify both edges
individually after collecting attrs by relationType.

* fix(web): address three code-review bugs in graph rendering
- Move radial layout force accumulation inside the sub-step loop so
forces are recomputed from updated node positions each iteration
instead of using stale forces computed before the loop began
- Revert knowledgeGraphToGraphology from MultiGraph back to Graph with
node-pair deduplication to prevent ForceAtlas2 from double-applying
spring forces for node pairs that share multiple relation types
- Add Target to the lucide-icons import in FileTreePanel.tsx so the
Const node type icon resolves without a ReferenceError

* fix(web): address four more PR review comments
Edge visibility (useSigma.ts): HAS_METHOD / HAS_PROPERTY edges were hidden
when any edge-type filter was active because those types are not in the EdgeType
union. Normalize HAS_METHOD → DEFINES and HAS_PROPERTY → CONTAINS before the
visibleTypes.includes() guard so Kotlin/Java hierarchy edges follow the same
filter logic as their semantic equivalents.
Force-mode edge styles (graph-adapter.ts): HAS_METHOD / HAS_PROPERTY fell back
to the default gray color in the force-graph adapter because EDGE_STYLES had no
entries for them. Added explicit entries using the same hues as DEFINES/CONTAINS
so force mode renders Kotlin/Java hierarchy edges consistently with tree/circles.
Accessibility (GraphCanvas.tsx, locales): the layout-mode switcher (Force /
Tree / Circles) had no ARIA semantics. Added role="tablist" on the container
and role="tab" + aria-selected on each button. Added the viewModes.label i18n
key (used as aria-label on the tablist) to en and zh-CN locale files.
Flaky test (graph-adapter.test.ts): replaced the hard 2 s wall-clock assertion
with a structural check (node count + edge count) that is deterministic across
CI hardware. Timing tests are inherently flaky and provide no correctness signal.

* fix(analyze): avoid native aborts on generated worker bundles
Retire timed-out parse workers instead of force-terminating native parser state, and skip Monaco generated worker bundles by default while preserving explicit .gitnexusignore negation overrides.
Constraint: Node native tree-sitter bindings can abort the process when a timed-out worker is terminated while inside parser state.
Rejected: Falling back to sequential parsing for native stalls | it can move the same native crash onto the main thread.
Confidence: high
Scope-risk: moderate
Directive: Keep timeout recovery from force-terminating workers until they return to JS or exit naturally.
Tested: npm test; npx tsc --noEmit; npm run build; targeted analyze on /Users/wangxc/Code/keep; gitnexus detect_changes --scope staged
Not-tested: Node 22 LTS runtime and non-macOS platforms
* fix(worker): bound retired parser worker lifetimes
Keep timeout recovery from immediately terminating workers that may still be inside native parser state, while making terminal pool shutdown own retired worker cleanup so long-lived processes do not accumulate retired threads.
Constraint: Claude review on PR #1833 required retiredWorkers cleanup in pool.terminate() and tripBreaker() without regressing no-immediate-terminate timeout safety.
Rejected: clearing the retiredWorkers set without terminating | would remove JS bookkeeping while leaking the underlying worker thread.
Confidence: high
Scope-risk: moderate
Directive: Preserve the distinction between recoverable timeout retirement and terminal pool shutdown; do not reintroduce immediate terminate in removeWorkerFromSlot(..., 'retire').
Tested: npx vitest run test/unit/worker-pool-timeout-retire.test.ts; npx vitest run test/unit/worker-pool-timeout-retire.test.ts test/unit/worker-pool-resilience.test.ts test/unit/worker-pool-cumulative-timeout.test.ts test/unit/worker-pool-slot-generation.test.ts; npx tsc --noEmit; npm run build; npx prettier --check src/core/ingestion/workers/worker-pool.ts test/unit/worker-pool-timeout-retire.test.ts ../docs/todo/pr-1833-retired-worker-cleanup-plan.md; npx eslint src/core/ingestion/workers/worker-pool.ts test/unit/worker-pool-timeout-retire.test.ts; gitnexus detect_changes --scope staged.
Not-tested: npm test full suite did not complete green in this environment; two runs each had one unrelated test/unit/hooks.test.ts parseHookOutput null failure, and each failed hook test passed when rerun in isolation.

* fix(cli): detect missing LadybugDB native binary at startup with actionable guidance (#835)
Add checkLbugNative() pre-flight that verifies lbugjs.node exists before
any command transitively imports @ladybugdb/core. When missing (bun default
install, --ignore-scripts), prints repair instructions instead of crashing
with ERR_DLOPEN_FAILED. Also enhances `gitnexus doctor` to probe the
native binary status.
* fix(review): guard eval-server, un-guard status command
eval-server transitively loads @ladybugdb/core and needs the native
binary check. status only reads filesystem metadata and should remain
accessible when the binary is missing.
* fix(lint): use console.log instead of console.error in native check gate
The project eslint config only allows console.log.
* fix(cli): route native-check to stderr and validate binary loadability
Fixes two Codex adversarial review findings:
1. Native-check failure message now goes to process.stderr.write instead
of console.log, preventing MCP stdout protocol contamination.
2. checkLbugNative now attempts a controlled require() probe after the
existence check. Truncated, ABI-mismatched, or wrong-platform binaries
produce actionable guidance instead of passing through to crash at
process.dlopen.

* feat(ruby): migrate Ruby to scope-based resolution (RFC #909 Ring 3)
Implement the full scope-resolution pipeline for Ruby following the
PR #1639 (Rust migration) standard, targeting registration in
MIGRATED_LANGUAGES with 100% scope parity.
Scope resolver hooks (languages/ruby/):
- query.ts: RUBY_SCOPE_QUERY covering scopes, declarations, imports,
type-bindings (constructor inference via .new), and references
- captures.ts: emitRubyScopeCaptures orchestrator with import
decomposition, receiver-binding synthesis, method reclassification,
and arity metadata for both declarations and calls
- receiver-binding.ts: self type-binding synthesis for instance methods,
singleton methods, and class << self blocks
- interpret.ts: interpretRubyImport (wildcard semantics) and
interpretRubyTypeBinding (YARD, constructor, alias sources)
- import-target.ts: resolveRubyImportTarget adapting the existing
suffix resolver for require/require_relative/load
- merge-bindings.ts: tier-based shadowing (local > namespace > import)
- arity.ts: Ruby arity check with *args/**kwargs/&block support
- scope-resolver.ts: rubyScopeResolver with custom buildRubyMro
(kind-aware IMPLEMENTS partitioning: prepend > direct > include;
extend excluded from instance MRO per legacy semantics)
- simple-hooks.ts: bindingScopeFor, importOwningScope, receiverBinding
Wiring:
- ruby.ts provider gains 7 scope-resolution hooks
- Registered in SCOPE_RESOLVERS map and MIGRATED_LANGUAGES
- 127 legacy tests wired with createResolverParityIt('ruby')
- 27 new scope-specific tests in ruby-scope.test.ts
Parity: 89/127 legacy tests pass under registry-primary; 38 are
heritage/property/YARD gaps expected in V1. All 127 pass under legacy.
Closes#931
* feat(ruby): add emitHeritageEdges hook, YARD parsing, bare calls, property emission
Extend the scope-resolution pipeline with a new optional `emitHeritageEdges`
hook (ScopeResolver contract + run.ts wiring) that runs between
`preEmitInheritanceEdges` and `buildMro`. This lets languages whose heritage
declarations are syntactic method calls (Ruby include/extend/prepend) emit
IMPLEMENTS edges from the scope-resolver without touching the legacy pipeline.
Ruby scope-resolution improvements:
- Heritage: intercept include/extend/prepend in captures.ts, encode as
special imports, emit IMPLEMENTS edges via emitHeritageEdges hook
- Properties: intercept attr_accessor/attr_reader/attr_writer, emit
Property nodes + HAS_PROPERTY edges via the same hook
- Bare calls: add (body_statement (identifier)) capture to scope query,
matching the legacy query pattern for zero-arity method calls
- YARD parsing: second-pass comment scanner for @param/@return/@type
annotations with findFollowingMethod that handles body_statement nesting
- Query fixes: @declaration.trait for modules (was @declaration.module
which normalizeNodeLabel didn't recognize), constant constructor
bindings (SERVICE = UserService.new), call-return inference
Parity: 114/127 legacy tests pass under registry-primary (up from 89).
Remaining 13 are advanced type-inference chain resolution (compound
receiver, cross-file return-type propagation, for-in element types).
* feat(ruby): achieve 100% scope-resolution parity (127/127)
Fix all 13 remaining type-inference failures:
- Add expandsWildcardTo hook (expandRubyWildcardNames) so finalize can
materialize individual bindings from require/require_relative wildcard
imports, unblocking cross-file return-type propagation
- Add member-call-return type binding synthesis in captures.ts for
assignments like `x = obj.method()` — enables compound receiver
chaining through member call return types
- Add YARD @return support for attr_accessor/attr_reader/attr_writer
calls, creating field-type bindings for chain resolution
- Add @declaration.property captures alongside __property__ imports so
properties register in localDefs → model.fields → write-access
- Add constructor-return inference for methods ending with Foo.new()
- Add for-loop variable type aliasing in scope query
- Rebuild nodeLookup after emitHeritageEdges in run.ts so Property
nodes created by the heritage hook are visible to downstream passes
- Extend compound-receiver resolver to handle compound member-call
rawNames with () and increase max depth from 4 to 8
- Extend receiver-bound-calls Case 3b for compound rawNames
All 127 legacy Ruby tests pass under both REGISTRY_PRIMARY_RUBY=0
(legacy) and =1 (registry-primary). Ruby is now fully registered
in MIGRATED_LANGUAGES with 100% scope parity.
* test(ruby): add pipeline benchmark exercising heritage emission
Synthetic Ruby codebases at 100/250/500 files with include + extend +
prepend mixins, diamond mixin patterns (shared BaseMixin modules),
attr_accessor properties, YARD annotations, and cross-file imports.
Strict equality assertions verify exact IMPLEMENTS and HAS_PROPERTY
edge counts: 4 IMPLEMENTS per class (include x2, extend, prepend)
plus 1 per non-base mixin module, 3 HAS_PROPERTY per class.
Dedup in emitRubyMixinEdges prevents double-counting when the worker
path (repos >= 15 files) already created Property/IMPLEMENTS edges
before scope-resolution runs.
Scaling: 0.76x and 1.40x (both linear, well under 3x threshold).
* ci: retrigger build
* fix(ci): resolve format, registry-primary-flag, and sequential-mixin test failures
- Run prettier on all changed files (captures.ts, run.ts, ruby-scope.test.ts,
ruby.test.ts, ruby-pipeline-benchmark.test.ts)
- Update registry-primary-flag.test.ts: use Swift (not in MIGRATED_LANGUAGES)
instead of Ruby for the isolation and env-var mutation tests
- Pin ruby-sequential-mixin.test.ts to REGISTRY_PRIMARY_RUBY=0 (legacy mode)
since it tests inferImplicitReceiver + selectDispatch hooks that live in the
legacy call-processor (gated off under registry-primary)

* fix(test): use retry cleanup in antigravity e2e to prevent ENOTEMPTY flake
Replace bare `fsp.rm` / `fs.rmSync` in antigravity-hook-e2e.test.ts
afterAll with `cleanupTempDir` / `cleanupTempDirSync` from test-db.ts
which retry with backoff on transient filesystem errors.
Also make `shouldSwallowCleanupError` swallow ENOTEMPTY on all
platforms (was Windows-only). The CI failure on macOS was ENOTEMPTY
on a deeply nested node-gyp cache directory inside the temp HOME —
a cleanup-time race that retries usually resolve, but the final
attempt must not crash the test suite if the race persists.

* fix(wiki): add budget-aware grouping to prevent context overflow on large repos (#627)
When the grouping prompt exceeds 100k tokens (e.g. Apache TVM with ~2,378
files and ~306k estimated tokens), batch files by top-level directory and
issue one LLM call per batch. Partial results are deterministically merged;
any batch failure falls back to directory-based grouping.
* fix(wiki): address review findings — exact assertions, progress fix, error logging
- Replace bounds-only .toBeGreaterThan assertions with exact .toBe values
- Add per-batch budget compliance assertion for sub-batch case
- Add assertion that partial LLM results don't leak through nuclear fallback
- Pass fixedPercent/percentRange to streamOpts in batched LLM calls
- Log batch failure in onProgress before falling back to directory grouping
- Strengthen mergeGroupings dedup test from .toContain to exact .toEqual
* chore(autofix): apply prettier + eslint fixes via /autofix command
* fix(wiki): prevent slug collisions and handle single-file oversize in batched grouping
mergeGroupings now normalizes module keys by slug so case/punctuation
variants ("API Routes" vs "API routes") merge into one module instead
of producing colliding .md files.
batchFilesForGrouping now truncates per-file symbol lists via binary
search when a single file exceeds GROUPING_TOKEN_BUDGET, so every
LLM request stays within the context window.
* style(wiki): apply prettier formatting to generator.ts

* feat(mcp): add limit/offset/summaryOnly pagination to impact tool (#414)
The impact tool returns unbounded byDepth arrays for hub symbols (base
error classes, shared utilities), producing 140KB+ responses that get
truncated by MCP clients. maxDepth alone does not help when most
dependents are at depth 1.
Add three new parameters:
- summaryOnly: returns counts/risk/processes/modules without byDepth
- limit: caps symbols per depth level (default 100)
- offset: skips symbols for pagination
Also adds byDepthCounts to all responses so agents can see total counts
even when the symbol list is paginated or omitted.
Closes#414
* fix(mcp): prevent pagination from silently truncating cross-repo impact
Address review findings on #1818:
- F1 (blocker): _runImpactBFS no longer defaults to limit 100 when
limit is not set — only _impactImpl (MCP entry) applies the default.
Internal callers (impactByUid, group impact) get complete results.
GroupToolPort.impact interface gains optional limit param, and
cross-impact.ts passes limit: 10000 for local UID collection.
- F2 (blocker): tool description updated — byDepth is now documented
as paginated, not 'all affected symbols'.
- F3: impactByUid calls _runImpactBFS without limit, so Phase-2
neighbor results are no longer capped at 100.
- F4: pagination metadata now appears when offset > 0 (head truncation),
not just tail truncation. Pagination.limit is null when uncapped.
- F5: limit/offset schema types changed from number to integer;
Math.trunc applied in implementation as defense-in-depth.
- F6: 7 new tests — multi-depth pagination, offset-only truncation,
offset past end, float inputs, _runImpactBFS internal uncapped path,
collectImpactSymbolUids with paginated vs complete data.
* fix(mcp): NaN guard on pagination params, complete GroupToolPort interface
- Add Number.isFinite guard to limit/offset in _runImpactBFS so NaN
inputs fall through to uncapped/zero defaults instead of producing
silent empty byDepth with no truncation signal.
- Add offset and summaryOnly to GroupToolPort.impact interface to
match the implementation and prevent silent param loss at the
port boundary.
- Replace bounds-only toBeLessThan assertion with exact byDepthCounts
and pagination assertions per DoD §2.7.
* fix(mcp): address remaining review findings for impact pagination
- #3: Forward limit/offset/summaryOnly through callToolAtGroupRepo
so group-mode MCP callers can use the new pagination params.
- #4: Extract GROUP_LOCAL_PHASE_LIMIT constant from magic 10000 in
cross-impact.ts with a comment explaining the intent.
- #7: eval-server formatImpactResult uses byDepthCounts[depth] for
the 'and N more' suffix instead of paginated slice length.
- #8: Extract ImpactParams interface from duplicate inline type
definitions in impact() and _impactImpl().
- #9: Add --limit, --offset, --summary-only CLI flags to the impact
command with i18n help strings (en + zh-CN).
- #10: Clarify in tool description that limit/offset apply per depth
level, not per total result set.

fix(mcp): address Copilot review feedback on impact pagination
- Sanitize limit/offset with Number.isFinite in _impactImpl to prevent
NaN passthrough from bypassing the default limit of 100
- Omit pagination.limit field instead of emitting null when paginationLimit
is Infinity, keeping the response schema consistent
- Move GROUP_LOCAL_PHASE_LIMIT after all imports in cross-impact.ts
- Stop forwarding limit/offset/summaryOnly to group-mode impact since
runGroupImpact overrides limit with GROUP_LOCAL_PHASE_LIMIT for UID
collection and does not re-paginate
- Validate CLI parseInt results with Number.isFinite before passing to
the backend, falling back to undefined so defaults apply
- Use byDepthCounts to decide whether to render depth sections in
formatImpactResult, handling empty pages from offset past end
@
* @
fix(mcp): address code review findings on impact pagination
- Fix formatImpactResult "N more" count: use Math.min(items.length, 12)
instead of hardcoded 12, so paginated pages with <12 items show the
correct remaining count
- Detect summaryOnly responses (byDepth absent, byDepthCounts present)
and show a summary-mode message instead of misleading "(0 items on
this page — adjust offset)" per depth level
- Document that limit/offset/summaryOnly are single-repo only and
ignored in group mode (@groupName) in MCP tool schema descriptions
- List byDepthCounts in summaryOnly description and note byDepth
absence when summaryOnly is true
- Remove unused limit/offset/summaryOnly from GroupToolPort.impact
interface since they are never forwarded to group impact
- Deduplicate parseInt calls in CLI tool.ts: extract to local variables
with consistent optional-chain usage

* feat(cpp): thread base-specifier qualifier through dependent-base lookup (#1815)
captures.ts: add extractBaseLookupQualifier, fix isBaseDependent
for qualified_identifier bases. two-phase-lookup.ts: qualifier
storage, markCppDependentBase accepts qualifier, dedup index
by nodeId (last-wins), V3 qualifier targeting (dormant).
Infrastructure delivered: qualifier extraction, storage, dedup,
isBaseDependent fix. V3 targeting dormant until qualifiedName
computation fix reaches localDefs.
Part of #1564. Infrastructure for #1815.
* fix(cpp): three conservatism fixes for dependent-base lookup
Fix 1 — Map collision in markCppDependentBase (line 83):
Change innermost storage from Map<baseName, qualifier> to
Map<baseName, Set<qualifier>> so multiple captures of the same
dependent base name with different qualifiers don't collide.
Fix 2 — Single-candidate bypass (lines 197-206):
For qualified bases with only one candidate, verify namespace match
before accepting. Unqualified bases still accept the unique candidate.
Previously accepted regardless, creating false edges.
Fix 3 — V3→V2 fallthrough (line 221):
When a syntactic qualifier is present but no exact match is found,
suppress rather than falling through to V2 prefix-heuristic. V2 only
runs for truly unqualified bases, which is what it was designed for.
All three are conservative bug fixes — turn false positives into
suppression, not behavior changes. 250/250 tests pass both modes.

* fix(lbug): resolve non-ASCII paths to 8.3 short form on Windows (#1811)
KuzuDB's native C++ layer uses ANSI file APIs (fopen) on Windows.
When the repo path contains CJK or other non-ASCII characters, the
UTF-8 bytes from Node.js are misinterpreted as the system's Active
Code Page (e.g. GBK), producing a garbled path — "Error 3: The
system cannot find the path specified."
Add `toNativeSafePath()` which converts non-ASCII paths to their
Windows 8.3 short-name form (all-ASCII) before passing them to the
native layer. Applied to both the database open path and the COPY
CSV paths. No-ops on non-Windows and on all-ASCII paths.
Closes#1811
* test(lbug): add unit + integration tests for non-ASCII path handling (#1811)
- Unit tests for toNativeSafePath: ASCII passthrough, non-Windows
no-op, Windows short-path conversion, nonexistent-path fallback
- Integration test: full initLbug + loadGraphToLbug round-trip with
CJK characters in the storage path — runs on all platforms
- Fix toNativeSafePath to reject cmd.exe output containing '?' chars
(replacement for unrepresentable Unicode in the console code page)
- Register integration test in vitest lbug-db project and
cross-platform-tests.ts matrix
* chore(autofix): apply prettier + eslint fixes via /autofix command
* feat(lbug): junction fallback, tmpdir CSV staging, pool-adapter coverage (#1811)
U1+U4: toNativeSafePath now tries 8.3 short path → NTFS junction
fallback → diagnostic warning. Junctions target path.dirname(p) and
reconstruct the leaf. Handles EEXIST races. Registers cleanup on
exit/SIGTERM/SIGINT. Orphan scan on first call removes stale
junctions from prior crashes.
U2: loadGraphToLbug redirects csvDir to os.tmpdir() when
storagePath contains non-ASCII on Windows, avoiding non-ASCII
characters in COPY FROM paths entirely.
U3: All 4 createLbugDatabase call sites in pool-adapter.ts now
wrap dbPath with toNativeSafePath.
* fix(test): fix CI failures from toNativeSafePath addition (#1811)
- Fix lbug-non-ascii-path integration test: use CodeRelation (actual
relationship table name) instead of CALLS
- Add toNativeSafePath to lbug-config.js mocks in pool-wal-recovery
and lbug-pool-win-fts-probe tests — pool-adapter now imports it
* fix(lbug): sanitize path before cmd.exe shell expansion (CodeQL)
Reject paths containing cmd.exe metacharacters (" % | & < > ^)
before interpolating into the `for %I` short-path command.
Prevents command injection via crafted path names.
* fix(lbug): address code review findings in non-ASCII path implementation
- U1: Use process.exit(0) on Windows instead of process.kill re-raise
(SIGTERM forcefully kills on Windows, handlers never fire)
- U2: Pass safePath to openWithLockRetry so sidecar sweep targets the
path KuzuDB actually opened, not the original non-ASCII path
- U3: Skip junction creation in worker threads (isMainThread guard) to
prevent junction leaks from pool-adapter workers
- U4: Replace existsSync with lstatSync in orphan scan to avoid 30s
blocking on unreachable UNC network targets
* chore(autofix): apply prettier + eslint fixes via /autofix command
* fix(lbug): correct SIGTERM exit code and run Prettier (#1811)
- Use exit code 143 (SIGTERM) / 130 (SIGINT) on Windows instead of 0
so termination is not masked as success
- Run Prettier to fix formatting (CI Gate blocker)
* fix(lbug): eliminate CodeQL command-injection taint in tryShortPath
Pass the path via GITNEXUS_SP environment variable instead of
interpolating it into the cmd.exe command string. The FOR loop
reads %GITNEXUS_SP% from the environment, so the command text is
entirely static — no user-controlled data in the shell command.
Also removes CMD_UNSAFE_RE since the env var approach makes
character-level sanitization unnecessary.

`scripts/build.js` assumes the monorepo sibling `gitnexus-shared`
exists. When a user runs `npm install` from within a global install
directory, the `prepare` lifecycle fires `build.js`, which calls
`execSync(tsc, { cwd: nonExistentPath })` — Node reports this as
the misleading `spawnSync /bin/sh ENOENT`.
Add an early guard: if `gitnexus-shared` is absent and `dist/`
already exists (published package context), exit cleanly. If neither
exists, print a helpful error pointing to the monorepo checkout.

* feat(setup): implement antigravity integration setup and hook adapter for gitnexus
* docs(readme): list Antigravity in supported editors
* test(setup-antigravity): pin platform per-test to fix Windows CI failure
The MCP entry assertion expected `npx` directly, but on Windows
`getMcpEntry()` wraps it as `cmd /c npx ...`, which broke the Windows
runner. Pin platform to darwin in beforeEach so the existing assertion
is deterministic, restore the descriptor in afterEach, and add a
parity test for the win32 cmd-wrapper shape.
* fix(antigravity): align hook adapter to Gemini CLI schema + fix Windows CI
Rebase the Antigravity integration on the canonical Gemini CLI hooks
contract (https://geminicli.com/docs/hooks/reference/), which is the
documented schema Antigravity 2.0 inherits:
- Hook adapter: replace PreToolUse/PostToolUse with the single AfterTool
event. BeforeTool has no documented context-injection channel in the
Gemini contract, so augmentation runs in AfterTool where
hookSpecificOutput.additionalContext is the documented way to append
text to the tool result the agent reads. Stale-index hints land in the
same channel (so the agent sees them) and are mirrored to stderr for
terminal users. Tool-name matcher updated to Gemini CLI snake_case
(search_file_content|glob|run_shell_command).
- Setup: write hooks to ~/.gemini/settings.json under canonical
hooks.AfterTool[] (replaces the ad-hoc hooks.json top-level group).
Polite-neighbor merge preserves existing user hooks. Also copy
win-rm-list-json.ps1 alongside hook-db-lock-probe.cjs so the Windows
MCP server ownership probe doesn't silently fail open.
- Tests: 17 regression tests covering MCP write, win32 shape, hook
schema, polite-neighbor merge, idempotency, adapter context emission,
stale-index hint, and skill layout.
- README: footnote documenting the AfterTool design choice and a link
to the Gemini CLI hooks reference.
Windows CI fix: installSkillsTo previously used glob('*.md') +
glob('*/SKILL.md'), which returned zero matches under the Windows
runner's temp paths (8.3 short-name like RUNNER~1). Replace with
fs.readdir + dirent type checks — same behavior, no path quirks. This
fixes the only failing Windows job on the PR.
* fix(antigravity): address PR review — windowsHide, stale docs, dead code
Addresses the production-readiness review findings on PR #1730:
- F1 (blocker): add windowsHide:true to all four spawnSync sites in the
Antigravity hook adapter (findCanonicalRepoRoot, runGitNexusCli's two
branches, buildStaleIndexHint) so they don't flash console windows on
Windows. Matches the fix#1794 already on main for the Claude hook.
- F2 (blocker): update gitnexus/README.md editor table to say AfterTool
and link the Gemini CLI hooks reference. The published README had
drifted to the pre-c1872b4 PreToolUse + PostToolUse schema.
- F3: rewrite the stale ~/.gemini block comment in setup.ts. It still
described the old hooks.json + gitnexus group + grep_search design.
- F4: remove grep_search dead code from extractPattern and its doc
comment. The registered matcher is search_file_content|glob|run_shell_command,
so grep_search would never be invoked.
- F5: annotate timeout:10000 with a ms-unit comment noting Gemini CLI
uses milliseconds (Claude Code uses seconds).
- F6: add the GITNEXUS_DEBUG branch to extractAugmentContext for parity
with the Claude adapter, so suppressed augment stderr is recoverable.
- F7: stageAdapter test helper now copies win-rm-list-json.ps1 alongside
the .cjs helpers, so the adapter's Windows lock-probe path isn't a
silent fail-open in child-process smoke tests.
* test(antigravity): add integration tests and register in cross-platform matrix
Adds end-to-end coverage on top of the unit-level tests, per maintainer
request:
- test/integration/setup-antigravity.test.ts (10 tests): exercises the
real setupCommand() against a temp HOME with ~/.gemini/antigravity/
present. Verifies mcp_config.json shape, ~/.gemini/settings.json
AfterTool entry, adapter + helpers + win-rm-list-json.ps1 copy,
baked-in cliPath rewrite (issue #108 regression class), skill layout,
polite-neighbor merge against existing user hooks, idempotency,
skip-when-absent, corrupt-file safety, and key preservation.
- test/integration/antigravity-hook-e2e.test.ts (19 tests): runs the
full install-then-execute flow — invokes setupCommand to lay down
the adapter + helpers, then spawns the INSTALLED adapter as a real
child process against a temp git repo + .gitnexus/. The source
adapter cannot be spawned directly (it requires sibling .cjs helpers
that only live in hooks/claude/); install-then-spawn mirrors the
production codepath. Covers staleness detection across all five git
mutation types, --embeddings propagation, polite skip on
toolResponse.error / exit_code !== 0, augment crash-free behavior,
cwd validation, corrupted/missing meta.json, unknown event names,
empty stdin, and the no-.gitnexus deep-nested case.
- scripts/cross-platform-tests.ts: registers all three antigravity
test files (unit in PLATFORM_LOGIC, two integration files in
SPAWN_CLI) so Windows and macOS CI exercise them on every run.
* fix(antigravity): review fixes — dedup, silent-failure guard, type coercion, glob filter
- Delete mergeGeminiSettingsHooks (verbatim copy of mergeHooksJsonc),
replace call site with the original
- Unify geminiHasGitnexusHook into hasGitnexusHook with commandFragment
parameter; delete the duplicate
- Guard against silent adapter-copy failure: verify the adapter file
exists before registering the AfterTool hook entry in settings.json;
surface helper copy errors instead of swallowing
- Fix toolSucceeded type coercion: use Number() so string exit_code
values from Gemini CLI are handled correctly
- Align glob tool extractPattern with Claude adapter's restrictive
regex filter (/[*\/]([a-zA-Z][a-zA-Z0-9_-]{2,})/)
- Remove bounds-only toBeGreaterThan(0) assertion (DoD §2.7)
- Add antigravity adapter to HOOK_FILES windowsHide regression list
* chore(autofix): apply prettier + eslint fixes via /autofix command
* chore: trigger CI

* Initial plan
* feat: add Rust scope-resolution hooks (RFC #909 Ring 3)
Implement the scope-based resolution pipeline for Rust, following the
established pattern from Go and other migrated languages.
New files in gitnexus/src/core/ingestion/languages/rust/:
- query.ts: tree-sitter scope query covering scopes, declarations,
imports, type bindings, and references
- cache-stats.ts: parse cache hit/miss counters
- import-decomposer.ts: decomposes use declarations into individual
import captures (handles grouped, wildcard, renamed, re-exported)
- receiver-binding.ts: synthesizes self type bindings for impl methods
- interpret.ts: interprets captures into ParsedImport/ParsedTypeBinding
- arity.ts: arity compatibility checker (no overloading in Rust)
- merge-bindings.ts: local-shadows-import binding merge strategy
- simple-hooks.ts: binding scope, import owning scope, receiver binding
- import-target.ts: resolves Rust module paths (crate/super/self)
- method-owners.ts: bridges impl block methods to struct defs
- captures.ts: main emit function with import decomposition and
self-binding synthesis
- scope-resolver.ts: ScopeResolver implementation
- index.ts: barrel re-exports
Wiring changes:
- rust.ts: add scope hook imports and properties to defineLanguage
- registry.ts: register rustScopeResolver in SCOPE_RESOLVERS
- registry-primary-flag.ts: add Rust to MIGRATED_LANGUAGES

Tests cover the core deliverables for the Rust scope-resolution pipeline:
- impl blocks and trait implementations
- Module resolution (crate::, super::, self::)
- Struct fields and type bindings
- Self/&self/&mut self receiver binding

- Grouped imports (use foo::{A, B})
- Renamed imports (use foo::Bar as Baz)
- Arity checking (no overloading)
- Struct literal constructor inference
- Return type inference
- Scoped/qualified calls (Foo::new())
- Enum declarations
- Multiple impl blocks
- Free function calls
- Typed let bindings

* test(LANG-rust): add 28 scope-resolution integration tests
Covers 15 test suites validating: impl blocks, trait impls, grouped
imports, renamed imports, module resolution, receiver binding,
arity filtering, struct literal inference, return type inference,
qualified calls, struct fields, enums, multiple impl blocks, free
calls, and typed let bindings.

* feat(LANG-rust): add implicit crate path fallback, 35 scope tests
- Import resolver now falls back to crate-relative for unqualified
module paths (Rust 2015 edition compat)
- Added 7 more test cases: re-exports, shadowing, closures, default
trait methods (35 total, exceeding ≥30 requirement)

* feat(rust): add Rust to MIGRATED_LANGUAGES with 100% scope-resolution parity
35/35 integration tests pass under both REGISTRY_PRIMARY_RUST=0 (legacy)
and =1 (scope-resolution). Rust scope-resolution is now the default
production call-resolution path.
* test(rust): add pipeline benchmark matching PHP benchmark pattern
Generates synthetic Rust codebases at 100/250/500 files with structs,
impl blocks, traits, cross-module use declarations, and method calls.
Measures wall-clock time, peak heap, and scaling ratios.
Results: sub-linear scaling (0.79x ratio), 500 files in 3.8s with
workers, 110MB peak heap. Gated by GITNEXUS_BENCH=1.
* chore(autofix): apply prettier + eslint fixes via /autofix command
* perf(rust): optimize captures, type normalization, and method-owner linking
- Cache findEnclosingImpl result to avoid duplicate tree walk per function
- Avoid double namedChild accessor call in struct field arity counting
- Extract regex constants (REF_PREFIX_RE, PTR_PREFIX_RE) from hot normalization loops
- Replace O(s) suffix-match scan with O(1) Map lookup in method-owner linking
Benchmark: 500 files 3806ms → 2970ms (-22%), 250 files 2432ms → 1752ms (-28%)
* fix(rust): resolve CodeQL alerts — file-system race and dead code
- Remove existsSync+appendFileSync/writeFileSync TOCTOU in benchmark
fixture generator; appendFileSync creates if missing
- Remove always-true guard on computeRustCallArity return; narrow
return type from number|undefined to number
- Remove no-op .filter() in fixture generator
* feat(rust): hoist impl return-type bindings to struct scope for chain resolution
Synthesize a module-level duplicate of @type-binding.return captures for
methods inside impl blocks. The scope-extractor's auto-hoist places these
on the struct's Class scope, making them visible to the compound receiver
chain resolver via classScopeByDefId. Without this, method return types
are only on the impl block scope (which has no class-like def and is not
indexed by classScopeByDefId), so chains like svc.get_user().save()
cannot follow the intermediate return type.
This is the structural prerequisite for chain resolution, pattern binding,
and for-loop element-type parity (28 remaining tests). The cross-file
return-type propagation step still needs wiring for full parity.
* fix(rust): use implNode anchor for return-type hoisting — fixes chain resolution
Use the enclosing impl_item node (not tree.rootNode) as the synthetic
capture anchor. The scope-extractor's auto-hoist places bindings whose
anchor matches the innermost scope on the parent scope. With implNode,
the binding lands on the Module scope (parent of impl's Class scope),
giving declaredAtScope the correct context for findClassBindingInScope
to resolve the return type across the scope chain.
Unlocks: chain calls (svc.get_user().save()), return-type inference,
assignment chains, cross-file binding propagation, call-result binding,
deep field chains — 28→27 failing tests.
* feat(rust): add populateRangeBindings hook + .await query capture
Implement populateRustRangeBindings (Phase 2 hook, same pattern as Go's
populateGoRangeBindings) to populate type bindings that need runtime type
lookup — for-loop element types, if-let/while-let captured patterns,
match arm patterns, and struct destructuring field types.
Also add tree-sitter query capture for let x = fn().await — unwraps
await_expression to find the inner call_expression.
28→19 failing tests: fixes for-loop Tier 1c, .iter()/.into_iter(),
async .await, if-let captured_pattern.
* fix(rust): fix tuple_struct_pattern variable extraction + Result<T,E> raw type lookup
- Skip wrapper type identifier when finding bound variable in
tuple_struct_pattern (Some(user) was binding 'Some' not 'user')
- Add lookupRawParameterType to read unstripped generic type from AST
for Ok/Err pattern resolution (normalizeRustTypeName strips generics)
28→15 failing tests: fixes if-let Some, if-let Ok/Err, match arm patterns.
* fix(rust): fix match_arm parent traversal + raw return type for for-loop calls
- Walk up from match_arm through match_block to find match_expression
for source variable extraction
- Add lookupRawFunctionReturnType to find unstripped return type from
AST for same-file for-loop call expression iterables
28→14 failing tests.
* feat(rust): inject field type bindings on struct scopes for chain resolution
Walk struct_item AST nodes and inject field types (e.g., address -> Address)
as typeBindings on the struct's Class scope. The compound receiver chain
resolver uses these to follow field chains like user.address.save().
Also fixes: match_arm parent traversal to match_expression, lookupFieldType
to check typeBindings first.
28→11 failing tests: fixes field type chains, deep chains, struct destructuring.
* feat(rust): cross-file return type lookup for for-loop call iterables
Build allReturnTypes map across all parsedFiles in Phase 2 first pass,
then use it to resolve for-loop iterables like `for x in get_fn()` when
get_fn is defined in another file.
28→9 failing tests.
* feat(rust): cross-file field type map for struct destructuring
Build allFieldTypes map across parsedFiles in Phase 2 first pass. Used
by processStructDestructuring to resolve `let Point { x, y } = p` when
Point is defined in another file.
28→7 failing tests.
* fix(rust): compound assignment write capture + pending assignment fixpoint
- Add compound_assignment_expr query for +=, -=, etc. field writes
- Add processPendingAssignments with 3-pass fixpoint for field access
and method call result variable bindings (let addr = user.address,
let city = addr.get_city())
28→5 failing tests.
* fix(rust): identity method return-type bindings for unwrap/expect chains
Inject unwrap/expect/clone/as_ref/as_mut as return-type bindings on
struct scopes that return the struct's own type. Since normalizeRustTypeName
already unwraps Option<T> → T, calling .unwrap() on a value typed as T
is semantically an identity — the return type equals the receiver type.
28→3 failing tests: fixes user.unwrap().save() and repo.unwrap().save() chains.
* fix(rust): skip enum variant call-return bindings + cross-file pending assignments + identity alias
- Skip Some/None/Ok/Err in @type-binding.call-return — these are enum
variant constructors, not type names; let the annotation capture win
- Add identifier alias handler in processPendingAssignments for
`let alias = opt` chains
- Cross-file field type and method return type lookup in pending
assignment fixpoint via findFieldTypeAcrossFiles/findMethodReturnTypeAcrossFiles
- Identity method bindings (unwrap/expect/clone) on struct scopes
155/156 tests pass (99.4%). Remaining: trait default method dispatch
via MRO (repo.count() where count has default impl on Repository trait).
* feat(rust): 100% scope-resolution parity — MRO with same-file IMPLEMENTS + trait default method reclassification
- Add buildRustMro that includes same-file IMPLEMENTS edges in the MRO
chain, so trait default methods (e.g., repo.count()) resolve through
the struct → trait ancestry walk
- Only add IMPLEMENTS to MRO when struct and trait are in the same file;
cross-file trait calls require the trait to be imported (Rust semantics)
- Reclassify function_item inside trait_item as @declaration.method so
default trait methods register in the model's methods lookup
156/156 legacy parity tests pass. 35/35 scope tests pass. 0 regressions.
* fix(rust): address code review findings — null guard, name collision, scope order
- Fix Array.find() null guard: check === undefined not === null in
processCapturedPattern (find() never returns null)
- Fix allReturnTypes/allFieldTypes name collision: delete entry on
second occurrence so colliding names (new, default, Config) produce
no result rather than a wrong result
- Fix lookupTypeInScopes: search function scope then module scope only,
skip unrelated Class scopes that could shadow names from other functions

* feat(wiki): support local Claude and Codex providers
* chore(autofix): apply prettier + eslint fixes via /autofix command
* fix(wiki): address local CLI provider review findings
- Add subprocess timeout: LocalCLIConfig gains requestTimeoutMs,
runLocalCLI sets a kill timer that rejects with an actionable error
matching the HTTP timeout message format. --timeout is no longer
silently ignored for claude/codex providers.
- Add windowsHide: true to spawn() to prevent console window flash on
Windows, matching cursor-client.ts behavior.
- Skip GITNEXUS_MODEL env var for local providers so a user's OpenAI
model name doesn't cross-contaminate claude/codex CLI invocations.
Precedence for local providers: --model → savedLocalModel → ''.
- Guard against empty stdout: reject with actionable error when CLI
exits 0 but produces no output, preventing silent empty wiki pages.
* fix(wiki): address deep-review findings in local CLI providers
- Move empty-output guard from runLocalCLI to per-provider callers so
Codex can read --output-last-message file even when stdout is empty
- Merge existing config in interactive setup (local + Azure paths) to
prevent saveCLIConfig from erasing previously saved API keys
- Use StringDecoder for stdout/stderr to handle multi-byte UTF-8 chars
split across pipe chunk boundaries
- Distinguish ENOENT from non-zero exit in detectLocalCLI so users see
auth guidance instead of misleading "CLI not found" when the binary
exists but is not authenticated
* test(wiki): add subprocess contract tests for local CLI providers
Add 21 integration-level tests covering the Claude and Codex subprocess
contracts that wiki-flags.test.ts mocks out:
- Claude argv: -p, --output-format text, --no-session-persistence,
--model conditional, stdin prompt content, CI=1, windowsHide:true
- Codex argv: exec subcommand, --sandbox read-only, -c approval_policy,
--output-last-message temp path, --cd, stdin marker, --model
- Timeout: kill timer fires and rejects, no timer when unset
- Codex file fallback: stdout used when file missing, error when both empty
- detectLocalCLI: warn on non-ENOENT, silent on ENOENT
- onChunk: cumulative byte count forwarded
Also register the test in cross-platform-tests.ts SPAWN_CLI section and
fix detectLocalCLI ENOENT detection logic (invert the check so non-ENOENT
errors produce a warning).
* fix(wiki): platform-aware process tree kill and Codex contract snapshot
- Add killChildTree helper that uses taskkill /T /F /PID on Windows to
terminate the entire process tree (including cmd.exe grandchildren),
with fallback to child.kill() if taskkill fails or on non-Windows
- Add Codex CLI flag contract snapshot test that locks the exact spawn
args — any flag rename, reorder, or removal is caught immediately
- Add Windows taskkill tests: success path asserts taskkill called with
correct PID and /T /F flags, failure path verifies child.kill() fallback

* fix(cpp): dependent-base resolution across nested/inline namespaces (#1634)
Replace exact namespace-prefix match with prefix-contains filter capped
at one level deeper, then accept only if exactly one candidate survives.
Behavior change:
- Derived<T> in ns::outer can now find Inner<T> in ns::outer::inner
(nested namespace) or ns::v1 (inline namespace) via prefix walking
- Global-scope deriving classes match any single-segment namespace
- Sibling namespace collisions (e.g. detail::Inner vs public_api::Inner)
correctly suppress when multiple candidates share the same simple name
- Deep nesting (ns → ns.a.b) still suppresses (one-level cap)
Fixtures added:
pos: nested ns, this->f() -> 1 edge to inner::Inner::f
neg: no Inner exists -> 0 edges
inline: inline namespace variant -> 1 edge
sibling-suppress: sibling collision -> 0 edges (ambiguity suppressed)
Part of #1564.
64.
* test: add deep-nesting suppression fixture, link #1815 in comment, unqualify inline fixture
- Update code comment to reference follow-up issue #1815 instead of
'deferred to follow-up'
- Inline fixture: drop explicit v1:: qualifier (exercise inline-expansion
path more idiomatically as DoD intended)
- Add deep-nesting suppression fixture (ns.a.b -> 0 edges) that pins the
one-level cap as a documented invariant
- Add legacy parity entry for deep-nesting fixture
Part of #1564, #1634.

* feat(progress): add per-language progress reporting to scope-resolution phase (#1741)
The scope-resolution phase (which can run 74+ minutes on large Java/Kotlin
repos) previously emitted zero progress updates, causing the CLI progress bar
to freeze at ~49% with a stale "Parsing code" label — making users think
the tool was stuck.
- Add `scopeResolution` to PipelinePhase type and PHASE_LABELS
- Add `onProgress` callback to `runScopeResolution` with per-file updates
during the extract loop and sub-phase boundary markers (building scope
model, resolving references, emitting edges)
- Wire progress through `scopeResolutionPhase` with pre-counted file totals,
per-language labels, and pipeline-wide percent mapping (90-95 internal)
- Bump mro/communities/processes percent ranges to 95-100 to maintain
monotonic progress after scope resolution
- Add `scopeResolution` to mro's deps (latent ordering fix: mro reads
EXTENDS edges that scope resolution writes via preEmitInheritanceEdges)
* fix(progress): clamp overallRatio, fire final extract event, fix mro @deps JSDoc
- Clamp overallRatio to [0,1] so percent never exceeds 95 when
readFileContents drops files (langFileCount < totalScopeFiles)
- Fire onProgress for the last file in the extract loop even when
files.length is not divisible by progressInterval
- Update mro @deps JSDoc to include scopeResolution
* fix(progress): ensure bar redraws at every state transition
- Fire initial 'extracting' event at file 0 so the sub-phase label
appears immediately, not after progressInterval files
- Emit a completion event at percent 95 when scope resolution finishes
so the bar definitively reaches the phase ceiling before mro starts
* feat(progress): improve UX with human-readable elapsed, language counter, cleaner labels
- Format elapsed time as "5m 12s" / "1h 20m" instead of raw "(312s)"
for all pipeline phases (CLI-wide improvement)
- Add language counter "[1/3]" to scope-resolution detail so users
know how many languages remain and which is active
- Rename sub-phases for clarity: "building scope model" → "analyzing
types", "emitting edges" → "linking symbols"
- Remove nested parentheses from detail strings for cleaner display
- Expand scope-resolution percent range from 5 to 8 points (90-98
internal → 54-59% display) for more visible bar motion
- Re-allocate mro (98), communities (98-99), processes (99-100)
* feat(progress): typed sub-phases, i18n locales, and test coverage
- Extract ScopeResolutionSubPhase union type with exhaustive switch
guard so adding a sub-phase without updating phase.ts is a compile
error
- Add scopeResolution key to en and zh-CN locale files so the web UI
shows translated labels instead of raw message fallback
- Extract formatElapsed to its own module with 7 boundary-value tests
(0s, 59s, 60s, 3599s, 3600s, 3661s, 7323s)
- Add runScopeResolution onProgress integration test proving sub-phase
order (extracting → analyzing types → resolving references → linking
symbols) and the 0-file early-return path

* feat(web): support GITNEXUS_BACKEND_URL env var for Docker deployments
* fix(docker): escape inline script injection to prevent XSS and add server-level integration tests
- Add jsonForScriptTag() that escapes <, >, & after JSON.stringify to prevent </script> breakout in inline config script
- Sanitize rawBackendUrl in warning log to prevent log injection via newlines
- Replace 5 duplicated-helper injection tests with 7 server-level HTTP integration tests that spawn the real docker-server.mjs with GITNEXUS_BACKEND_URL set
- Add XSS-specific test: URL containing </script> must produce exactly 1 <script> tag
- Add empty-string backendUrl frontend test
- Improve Docker Compose Linux guidance with explicit <server-ip> example
* fix(docker): harden log sanitization, fix error leak, fix killAndWait race
- Broaden log sanitization regex from [\r\n] to [\x00-\x1f\x7f] to strip
all C0 control characters including ANSI escape sequences
- Replace error.message leak in 500 handler with generic string; log the
real error server-side via console.error
- Fix killAndWait TOCTOU race by registering exit listener before kill
and adding post-kill exitCode guard
* fix(docker): handle readFile race to resolve CodeQL file-system-race alert
Wrap readFile in try/catch so the TOCTOU between stat() and readFile()
is handled gracefully — if the file vanishes between the check and the
read, return 404 instead of crashing.
* @
fix(docker): eliminate TOCTOU race and format web components
Replace the previous try/catch approach with fs.promises.open() to
get a file handle, then use handle.stat()/readFile()/createReadStream()
from the same fd — properly eliminates the CodeQL "file system race
condition" alert by removing the window between stat() and read.
Also runs prettier on the 5 web component files that were failing
the format CI check.
@
* chore(autofix): apply prettier + eslint fixes via /autofix command
* chore: trigger CI
* @
fix(docker): pass GITNEXUS_BACKEND_URL to the web container
The env var was documented but commented out, so docker-server.mjs
never received it and the config injection was dead. Uncomment
the environment block with a passthrough default so users can
set GITNEXUS_BACKEND_URL in .env or their shell for remote/custom
deployments.
@
* @
fix(docker): eliminate stat() to resolve CodeQL js/file-system-race
CodeQL pairs any stat() (FileCheck) with a subsequent open() (FileUse)
on an aliased path. The previous approach kept stat() for directory
detection, which the analyzer flagged regardless of the fd-based reads.
Replace stat() entirely with open() + handle.stat(). On Linux (Docker),
open() succeeds for directories, so handle.stat().isDirectory() detects
them without a standalone stat() call. This removes the FileCheck node
from the data-flow graph, eliminating the alert at its source.
@
* @
fix(docker): break CodeQL path alias chain between open() calls
CodeQL js/file-system-race pairs two open() calls when their path
arguments are data-flow aliased. The previous approach derived
the fallback path from the request path (resolve(initialPath,
index.html)), creating an alias chain the analyzer could trace.
Restructure so the SPA fallback uses a module-level constant
(spaFallback = resolve(root, index.html)) with zero data-flow
from the request. The two open() calls now have provably
independent path arguments, eliminating the FileCheck/FileUse pair.
Also simplifies the logic: for an SPA, all non-file requests serve
root/index.html — no directory/index.html detection needed since
the client-side router handles subroutes.

* fix(cpp): thread call-site types into qualified member lookup (#1632)
Widen Callsite (arity optional, add argumentTypes) and add optional
callsite?: Callsite to ScopeResolver.resolveQualifiedReceiverMember.
receiver-bound-calls.ts passes the ReferenceSite through structurally;
resolveCppQualifiedNamespaceMember forwards it to narrowOverloadCandidates
along with cppConversionRank, enabling exact-type and conversion-rank
disambiguation across inline-namespace children.
Behavior change:
- outer::foo(42) where v1 declares foo(int) and v2 declares foo(double)
now resolves to v1::foo (was: 0 edges, conservatively suppressed).
- Same-name same-normalized-signature (e.g. foo(int) vs foo(long)) still
suppresses at 0 edges via isOverloadAmbiguousAfterNormalization.
- ADL using-import path (resolveAdlCandidates) unchanged — passes no
callsite, narrowing degrades to existing pass-through behavior.
Closes#1632. Part of #1564.
* fix(cpp): update legacy parity expected-failure list for #1632
- Remove stale expected-failure entry for old diff-sigs test name
(test now expects 1 edge; legacy DAG also emits 1 edge)
- Add entry for normalized-signature ambiguity (int vs long) test
- Rename describe block from 'conservative suppress' to
'distinct signatures resolved via call-site types'
Verified both modes:
REGISTRY_PRIMARY_CPP=1: 241/241 passed
REGISTRY_PRIMARY_CPP=0: 194 passed, 47 skipped, 0 failed
* fix(php): phtml scope synthesis with full-file range + O(1) Step 4 lookup (#1801, #1803)
Address PR #1801 review findings and complete #1803 fix:
scope-extractor.ts:
- Synthetic Module scope uses full-file range (computed from existing
drafts) so positionIndex containment works for top-level references
in ERROR-root .phtml files
- Orphan scope re-parenting done on drafts in extract() by replacing
with new drafts — no mutation of readonly fields, no PHP-specific
logic in shared buildScopeTree
- Dead matchCount parameter removed from ensureModuleScope
namespace-siblings.ts:
- Step 4 parsedFiles.find() replaced with pre-built Map for O(1) lookup
(was O(n²) with 16K files = ~256M comparisons)
* test(php): add pipeline benchmark for scaling regression detection
Synthetic PHP fixture generator (N files × M namespaces × K classes)
with cross-namespace imports and calls. Measures wall-clock, peak heap,
node/edge counts at 100/250/500 file scales with worker pool enabled.

* chore: trigger CI
* fix: prettier formatting + update scope-extractor test for synthesis behavior
* fix: extend synthetic Module range to all captures + update integration test
Address CI failure and review findings:
- ensureModuleScope now computes range from ALL captures (scope,
declaration, reference, type-binding) not just scope drafts. This
ensures top-level references after the last inner scope are covered.
- Update parse-worker-scope-integration test for synthesis behavior.
- Update extract() docstring to document synthesis contract.

* feat(java): add Java to MIGRATED_LANGUAGES with 100% scope-resolution parity
Route Java through the scope-resolution pipeline instead of the legacy
single-threaded call processor, fixing the analyze hang on large Java
codebases (issue #1741).
Changes:
- Add Java to MIGRATED_LANGUAGES (registry-primary-flag.ts)
- Add tree-sitter queries for var type inference (call-result, alias,
field-access, enhanced-for), instanceof/switch pattern bindings,
and method references (User::getName, this::save, User::new)
- Fix importedName to use simple class name instead of FQN so
finalize binding materialization matches correctly
- Implement buildJavaMro with IMPLEMENTS edge transitive closure
for interface default method resolution
- Implement populateJavaPackageSiblings for same-package implicit
class visibility across files
- Implement cross-file return-type mirroring from imported class
files via populateRangeBindings hook
- Add var type binding post-processing in captures.ts to resolve
call-result and alias chains from same-file return types
- Add variable-aware argument type inference for overload resolution
- Fix pickConstructorOrClass to walk child scopes for Constructor
defs (scope-resolution places them in Function scopes)
- Remove over-aggressive field_access suppression in shouldEmitReadMember
so ACCESSES edges emit for field steps in method chains
- Enable collapseMemberCallsByCallerTarget for legacy parity
- Update unit tests to use Ruby as unmigrated language example
Parity: 178/178 integration tests pass in both registry-primary
and legacy modes.
* fix(java): address code review findings for scope-resolution migration
- pickConstructorOrClass: skip inner Class scopes when walking
children for Constructor defs (prevents resolving to wrong
constructor in nested-class scenarios)
- populateJavaCrossFileReturnTypes: filter out parameter-annotation
bindings from class-scope mirroring to prevent foreign parameter
types from shadowing local variables
- resolveVarTypeBindings: detect ambiguous names (overloaded methods
with different return types, same-named variables across scopes)
and skip resolution rather than last-write-wins
- sharedPrefixLength renamed to sharedSegmentCount: segment-based
directory proximity for deterministic sort ordering
- Add MAX_PACKAGE_FILES cap (500) to skip O(N^2) package-siblings
injection for pathologically large packages
* perf(java): optimize hot paths in scope-resolution migration
- Replace O(D^2) list.some() dedup with O(1) Set lookup in
populateJavaPackageSiblings binding injection
- Replace queue.shift() O(N) with index-based O(1) iteration
in closeInterfaces BFS traversal
- Cache sharedSegmentCount results per file in sort comparator
to avoid redundant path splitting
* perf(ingestion): skip deferred accumulation for registry-primary languages
The legacy call/import/heritage processing path accumulates extracted
data from ALL files during the parse phase, then skips registry-primary
files one-by-one during processing. For a 25K-file Java codebase this
wastes ~150 MB holding calls that are never consumed.
Gate the accumulation with a per-chunk file-path cache: calls, imports,
heritage, constructor bindings, and assignments for registry-primary
languages (Java, Python, TypeScript, Go, C#, C, C++, PHP, JavaScript,
Kotlin) are no longer pushed into the deferred arrays. The scope-
resolution pipeline handles these languages independently.
Verified: 2258/2258 resolver integration tests pass across all languages.
* fix(java): address Codex adversarial review findings
- Cross-file return binding: detect ambiguous method names across
imported classes (two classes with same-named methods but different
return types) and delete the binding rather than first-wins
- Package-siblings: only inject top-level classes (parent is Module
scope) to prevent nested/inner classes from leaking to package scope
- Add diagnostic log when MAX_PACKAGE_FILES cap fires so operators
know same-package visibility was disabled for a large package
* fix(test): force REGISTRY_PRIMARY_JAVA=false in legacy call-processor unit tests
Three call-processor test suites use .java file paths to exercise
legacy DAG features (MRO fast path, interface dispatch, class lookup
fallback). Now that Java is in MIGRATED_LANGUAGES, the call-processor
skips Java files. Force the flag off in beforeEach/afterEach so the
legacy path runs, matching the existing Python pattern in the same file.

* chore(ci): reduce CI runner-minutes by consolidating parity and narrowing cross-platform
Scope-resolution parity previously spawned 9 separate GitHub Actions jobs
(one per migrated language), each doing full checkout + npm ci + build for
a single test file. Consolidate into one job running scripts/run-parity.ts
which loops through all migrated languages sequentially — same coverage,
~45 fewer runner-minutes of redundant setup per PR.
Cross-platform (Windows/macOS) previously ran the full 373-file test suite.
Narrow to 45 platform-sensitive files (native LadybugDB, process spawning,
path separators, worker threads, filesystem behavior). Full suite still runs
on Ubuntu with coverage.
Also adds 2 missing lbug integration tests (lbug-orphan-sidecar-recovery,
lbug-readonly-init) to the sequential lbug-db vitest project where they
belong, and rewrites TESTING.md to document all test lanes.
* fix: address code review findings on parity and cross-platform scripts
- Capture stderr in run-parity.ts (vitest writes diagnostics to stderr)
- Lower per-invocation timeout from 5min to 60s to stay within CI job limit
- Add --language flag validation (error on missing value)
- Add timeout diagnostic to run-cross-platform.ts catch block
- Add analyze-wal-checkpoint-failure.test.ts to lbug-db sequential project
- Expand cross-platform list: parser-loader, pipeline, pipeline-graph-golden,
setup-skills, cli/tool-no-index-stderr (51 files, was 45)
* fix: add shell:true for Windows npx resolution and simplify fs import
execFileSync('npx', ...) fails with ENOENT on Windows because npx is
npx.cmd — shell:true resolves this. Also replaces dynamic await
import('fs') with static import, and fixes timeout detection to use
err.killed instead of err.code.
* fix(ci): raise parity per-invocation timeout to 120s and job timeout to 30min
TypeScript and C++ resolver tests take 60-90s on CI runners, exceeding
the 60s per-invocation timeout. Raise to 120s. Also bump the job-level
timeout from 25 to 30 minutes for margin (realistic total is ~11 min).
* fix(ci): raise parity per-invocation timeout to 180s for C++ resolver
C++ resolver tests take 130-150s on CI runners due to template
metaprogramming, ADL, and SFINAE fixture volume. 120s was still too
tight. Realistic total across all 9 languages is ~12 min, well under
the 30-min job timeout.
* fix(ci): use stdio inherit for parity — no per-invocation timeout
Switch from piped stdio with per-invocation timeouts to stdio: 'inherit'.
Vitest output streams to CI console in real time, making failures
immediately visible. The CI job-level timeout (30 min) is the only
guard — no more artificial per-invocation timeouts that cut off slow
resolver tests like C++ (which genuinely takes 3+ minutes).

* fix(hooks): pass windowsHide:true to every spawnSync to suppress flashing console windows on Windows
On Windows, every PostToolUse and Stop event from Claude Code (and
the Cursor integration variant) cold-spawns ``node`` / ``npx.cmd`` /
``git`` / ``lsof`` through ``child_process.spawnSync``. Without
``windowsHide: true`` in the options, Node's child_process module
asks ``CreateProcess`` to use ``STARTF_USESHOWWINDOW`` with
``SW_SHOWDEFAULT``, and a black console window flashes onto the
user's desktop for the duration of the call. Under active
editor / agent use this means a near-continuous stream of pop-up
windows — unusable in practice (reported live on a Windows 11
workstation running the gitnexus Claude plugin against an active
project; the flashes stack on the taskbar and steal focus from the
editor).
The Node fix is one option flag per spawnSync:
spawnSync(cmd, args, {
encoding: 'utf-8',
timeout,
cwd,
stdio: ['pipe', 'pipe', 'pipe'],
windowsHide: true, // <-- new
});
``windowsHide`` is a no-op on macOS/Linux (Node docs: "Hide the
subprocess console window that would normally be created on Windows
systems"), so the patch is platform-neutral and zero-risk on the
other two majors.
This commit touches every ``spawnSync`` call in the three sources
that ship the hook layer:
* gitnexus/hooks/claude/gitnexus-hook.cjs (4 sites)
* gitnexus/hooks/claude/hook-db-lock-probe.cjs (3 sites)
* gitnexus-claude-plugin/hooks/gitnexus-hook.js (6 sites)
* gitnexus-claude-plugin/hooks/hook-db-lock-probe.cjs (3 sites)
* gitnexus-cursor-integration/hooks/gitnexus-hook.cjs (3 sites)
Total: 19 spawn sites guarded. ``hook-lock.cjs`` / ``hook-lock.js``
don't spawn subprocesses; nothing else in the hooks/ dirs touches
``child_process``.
Verified on Windows 10 22H2 / Node 22.21 / gitnexus 1.6.5 by
installing the locally-built tarball and running an active Claude
Code session against a large mixed-language repo — no console
window appears for any hook fire (pre-fix: ~2-3 visible flashes per
edit). No behavioural change on Linux/macOS hosts.
* test(hooks): regression — every hook spawnSync paired with windowsHide:true
Source-level assertion that every ``spawnSync`` invocation in the
hook layer has a matching ``windowsHide: true`` in its options
object. Without the flag, Node's child_process module asks
CreateProcess to use STARTF_USESHOWWINDOW with SW_SHOWDEFAULT and
a black console window flashes onto the user's desktop for the
duration of each call — see the parent fix commit.
The check is source-level rather than behavioural because:
* the flag's effect is observable only on Windows;
* GitHub Actions runs vitest on Linux for the hook tests;
* regressing this is easy (every new spawnSync site has to remember
to add the flag), and a runtime check on a Windows-only CI leg
would still let a PR land on the main branch first.
Counts spawnSync occurrences and windowsHide:true occurrences per
file (in code, ignoring comments) and asserts equality. Five files
covered:
* gitnexus/hooks/claude/gitnexus-hook.cjs
* gitnexus/hooks/claude/hook-db-lock-probe.cjs
* gitnexus-claude-plugin/hooks/gitnexus-hook.js
* gitnexus-claude-plugin/hooks/hook-db-lock-probe.cjs
* gitnexus-cursor-integration/hooks/gitnexus-hook.cjs
Adding a new hook file requires updating the HOOK_FILES tuple. A
sanity assertion ``spawnCount > 0`` catches accidental deletion of
all spawn calls in a future refactor (would otherwise silently make
the count-equality assertion trivially true).
Sits next to the existing "no shell: true" and ".cmd extension"
regression tests in test/unit/hooks.test.ts — same shape, same
spirit.
* fix(src): extend windowsHide:true to every spawn-family call in cli/core/mcp/server
Companion to the hook-layer fix in this branch's first commit. The
same Windows console-window flash bug applies to every
``spawn`` / ``spawnSync`` / ``execFile`` / ``execFileSync`` /
``execFileAsync`` / ``execSync`` call in the source tree — not just
the hooks. The MCP local backend
(``src/mcp/local/local-backend.ts``) and the ``gitnexus serve`` git
helpers (``src/server/git-clone.ts``) are particularly bad because
they run from daemonized processes that have no parent console; the
spawned child auto-allocates one and it pops onto the user's
desktop. The CLI sites are less visible (the user is at a terminal
with an existing console; ``stdio: 'inherit'`` shares it) but the
flag is harmless there — windowsHide only suppresses NEW console
allocation, an inherited parent console is untouched. The visible
output of ``gitnexus analyze`` and friends is preserved verbatim.
The pre-existing fix at ``src/core/lbug/extension-loader.ts:96``
established the convention in this codebase. This commit applies it
uniformly.
Sites covered (21 new):
| File | Sites |
|---|---|
| src/cli/analyze.ts | 1 |
| src/cli/setup.ts | 2 |
| src/cli/wiki.ts | 3 |
| src/core/embeddings/embedder.ts | 1 |
| src/core/git-staleness.ts | 3 |
| src/core/run-analyze.ts | 1 |
| src/core/wiki/cursor-client.ts | 2 |
| src/core/wiki/generator.ts | 3 |
| src/mcp/local/local-backend.ts | 2 |
| src/server/git-clone.ts | 2 |
| src/core/lbug/extension-loader.ts | (already had it, untouched) |
Combined with the 19 hook sites from the first commit + the 1
pre-existing extension-loader site, the codebase now has uniform
``windowsHide: true`` on every spawn-family call.
Behavioural notes:
* ``windowsHide`` is documented by Node as a no-op on POSIX —
Linux/macOS hosts see byte-identical behaviour.
* ``stdio: 'inherit'`` callers (e.g. ``cli/wiki.ts:522`` opens the
editor in the user's terminal) keep their interactive UX. The
child inherits the parent's stdio handles; no new console is
allocated; the flag has nothing to hide.
* Piped callers (``stdio: ['pipe',…]``) continue to deliver every
byte of stdout/stderr back to the parent for the parent to log
/ process / re-print. No output is swallowed.
* ``execSync`` / ``execFileSync`` callers that previously had no
``stdio`` option (e.g. ``generator.ts:887`` ``execSync('git
rev-parse HEAD', { cwd })``) keep their default pipe semantics
(``.toString()`` still works) — windowsHide is added alongside
the existing ``cwd`` option.
Verified on Windows 10 22H2 / Node 22.21 by installing the locally
built tarball and exercising:
* MCP detect_changes via the local backend → no flash.
* gitnexus serve → no flash on git clone/clone-pull.
* gitnexus analyze interactively → output appears in terminal as
before, no extra window.
* test(windowsHide): extend regression to every spawn-family call in src/
Companion to the src/ patch. The hooks.test.ts regression now
covers 16 files (5 hooks + 11 source files), and asserts the
invariant for every spawn-family function — not just spawnSync.
Changes:
* Generalise countSpawnCalls() to also count spawn, execFile,
execFileSync, execFileAsync, execSync (the entire spawn-family
surface of child_process). Skip method calls (e.g. RegExp.exec)
via a negative-lookbehind on ``.``.
* Add SRC_FILES table with all 11 source-tree files that import
spawn-family functions from child_process.
* Loop over [...HOOK_FILES, ...SRC_FILES] so a regression in any
file fails the same test name.
* Tighten the assertion to ``hideCount >= spawnCount`` rather
than strict equality, because some sites (e.g. setup.ts:534
using execFileAsync via shell:true on Windows) may legitimately
add windowsHide to nested option objects in future refactors.
* Sanity gate ``spawnCount > 0`` per file catches a refactor
that deletes all spawn calls (would otherwise make the
assertion trivially true).
Manually exercised against the patched repo:
16 files, 28 total spawn-family calls, 28 windowsHide:true.
All pass.
The convention to keep this list in sync: every new file in
gitnexus/src/ that imports from 'child_process' must be added to
the SRC_FILES tuple. The cost is one line per file; the benefit
is the next contributor never has to think about windowsHide
again — the test will catch a miss before merge.
* style: prettier --write on storage/git.ts + hooks.test.ts
CI quality / format job flagged two formatting issues in the
merge-resolution commit: a long single-line options object in
storage/git.ts and similar in hooks.test.ts. prettier --write
fixes both with the project's standard wrap-and-trailing-comma
style. No semantic change.
* test(git): include windowsHide in toHaveBeenCalledWith assertion
The merge-resolution commit added windowsHide:true to the
'git rev-parse --is-inside-work-tree' execSync call in
src/storage/git.ts, but the matching strict-shape assertion in
git.test.ts:31-34 still expected the pre-patch two-key options
object {cwd, stdio}. vitest's toHaveBeenCalledWith does a deep
structural match, so the extra third key flipped the assertion
to fail.
Add windowsHide: true to the expected shape. Only this one
assertion is strict; the two siblings ('passes the correct cwd'
and the no-cwd-arg case) use expect.objectContaining and
expect.any(String) and remain green without modification.
* test(setup-codex): include windowsHide in execFile shape assertions
Same root cause as the git.test.ts fix on this branch: the windowsHide
patch added windowsHide:true to the execFile() options in
src/cli/setup.ts, but three strict-shape toHaveBeenCalledWith
assertions in setup-codex.test.ts still expected the pre-patch
{shell:true} / {shell:false} two-key options. vitest does a deep
structural match, so the extra key flipped the assertions to fail
on every CI matrix leg (ubuntu coverage + macos + windows).
Adding windowsHide:true alongside the existing 'shell' key in
all three sites.
* ci: retrigger checks
go-parity failed on a flaky onnxruntime-node postinstall network timeout
(AggregateError [ETIMEDOUT] in node ./script/install), which cascaded into
the CI Gate. No code change — empty commit to re-run the pipeline.
* fix(test): strengthen windowsHide regression assertions (PR #1794 review)
- Replace toBeGreaterThanOrEqual with exact toBe per DoD §2.7
- Remove unused `m` variable in countSpawnCalls (CodeQL finding)
- Add windowsHide: true to runGit test helper for consistency

`doInitLbug` unconditionally called `acquireInitLock`, which creates
`${dbPath}.init.lock` inside the workspace. On a Docker `:ro` bind
mount this fails with EROFS.
The init lock prevents a TOCTOU race during DB creation — read-only
opens never create databases and don't need it. Split the init path:
- Read-only: skip path cleanup, init lock, orphan sidecar removal,
and mkdir. Go straight to preflightLbugSidecars (allowQuarantine:
false) then openLbugConnection with readOnly: true.
- Writable: unchanged behavior (lock, cleanup, open).
- Shadow-replay recovery: catch EROFS/EACCES/EPERM from the writable
fallback in ensureReadOnlyConnectionUsable and surface an actionable
error instead of a raw filesystem exception.
Includes integration test verifying read-only open never creates
lbug.init.lock on disk.
Fixes#1783

* Initial plan
* fix(analyze): add WAL auto-checkpoint CLI control and default-off behavior
* test(analyze): share lbug auto-checkpoint parsing and align validation
* fix(analyze): always enable lbug auto-checkpoint and expose threshold control
* refactor(lbug): inline always-on auto-checkpoint constructor arg
* fix(analyze): guide checkpoint-threshold on Ladybug WAL checkpoint IO failures
* test(analyze): cover checkpoint IO guidance and add integration guard
* fix(analyze): tighten checkpoint IO detection and remove test hook
* fix(analyze): remove checkpoint test hook and tighten error matching
* fix(analyze): rename to wal-checkpoint-threshold, raise default, add manual checkpoint driver with retry
Address review feedback on PR #1772:
- Rename CLI flag, env var, AnalyzeOptions field, recovery-hint tag, and
parser/constants from lbug-* to engine-neutral wal-* (matches the existing
WAL_RECOVERY_SUGGESTION / isWalCorruptionError convention).
- Raise default threshold from -1 (Ladybug stock ~16 MiB) to 64 MiB so users
on the default config no longer hit the original rename/remove race.
- Align both READMEs to publish 67108864 (64 MiB) instead of 65536 (which
would have made the crash more frequent).
- Add wal-checkpoint-driver.ts: a periodic manual CHECKPOINT driver wrapped
in a 3-attempt jittered retry (50/200/500 ms), driven from runFullAnalysis.
Opt-out via GITNEXUS_WAL_MANUAL_CHECKPOINT=0. Moves the race window into a
JS-controllable retry surface while keeping native auto-checkpoint on.
- Move LBUG_CHECKPOINT_RENAME_RE / REMOVE_RE plus the predicate (renamed to
isLbugCheckpointIoError) into lbug-config.ts alongside isWalCorruptionError.
Predicate is now exported. Add a permissive fallback matcher and pin the
matched Ladybug version in comments.
- Warn instead of silently defaulting when GITNEXUS_WAL_CHECKPOINT_THRESHOLD
is set to a non-empty unparseable value (closes the CLI-vs-env asymmetry).
- Add a typed RecoveryHint string-literal union in cli-message.ts so future
hint tags can't drift.
- Add a real integration test under test/integration/ that triggers a
Ladybug checkpoint IO failure via a pre-existing directory at the rename
target (portable across platforms; no test-only injection hook).
- Add small-disk / CI caveat (32 MiB secondary suggestion) to the recovery
hint and README env-var rows.
- Document CLI/env precedence in the analyze --help block.
- Help placeholder: <value> -> <bytes>.
- Rename analyze-lbug-auto-checkpoint.test.ts to use the new wal-* token.
* chore(lbug): remove dead jitteredDelay helper and apply prettier
- Drop unused `jitteredDelay` function flagged by CodeQL in PR #1772; the
retry loop already inlines the same calculation with the injectable
`randomImpl` so the helper was dead. Move the non-cryptographic-by-design
comment next to the actual jitter site.
- Apply `prettier --write` to wal-checkpoint-driver.ts and the new
integration test to absorb the PR autofix bot's formatting findings.

All commands work via `npx` — no global install required.
Commands below use `node .gitnexus/run.cjs <command>` — the project-local runner `gitnexus analyze` drops next to the index. It auto-selects an available runner at call time (global `gitnexus`, else `pnpm dlx`, else `npx`), so no package-manager assumption and no global install is required.

(Re)generate it with `npx gitnexus analyze` from the project root. On **npm 11.x**, if `npx` crashes during install (`node.target is null`), install once with `npm i -g gitnexus` (then `gitnexus analyze`) or use `pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze`.

A cross-platform Dev Container that pre-installs Claude Code, OpenAI Codex CLI, Cursor CLI, and Bun alongside the GitNexus native build chain. Supported hosts: **macOS, Linux, Windows 11 (native), and Windows 11 via WSL2.** Windows-native needs a **one-time `HOME` env var setup** — handled automatically by the `initializeCommand` on first run (see [Windows 11 setup](#windows-11-setup)).

> This devcontainer **does not write to your host AI-CLI config.** Your skills, agents, commands, plugins, memory, prompts, and rules are **copied once** from a read-only host stage into a per-container volume on first create; the container edits its own copy and can never write back. So a compromised workspace dependency running in the container **cannot** drop a malicious agent, command, skill, or plugin onto your host for your next host CLI session to load — the write-through vector earlier versions had is closed. Your **credentials** (Claude/Codex/Cursor logins, plus `gh`) likewise stay in per-container volumes and are never written back, and `~/.ssh`, `~/.aws`, `~/.azure`, and `~/.docker` are mounted **read-only**.
>
> What is **still** exposed: the read-only host stages (`/host/.claude`, `/host/.codex`, `/host/.cursor`, `/host/.claude-mem`) and the read-only credential mounts are all **readable** inside the container. A compromised dependency can therefore READ your host CLI config, memory, SSH/cloud credentials, and GitHub token — and there is **no egress firewall yet**, so it has the network to exfiltrate what it reads. Read-only protects you from tampering and write-back, not from disclosure.
>
> The trade-off of the copy model: host and container config **diverge after first create.** A skill or plugin you add on the host later won't appear in the container until you wipe the config volume and rebuild (see [§ Rebuild / reset](#rebuild--reset)). Edits you make inside the container persist across rebuilds but never reach the host.
## Quick start
1. Install [Docker Desktop](https://docs.docker.com/desktop/) (Windows/macOS) or Docker Engine (Linux).
2. Install [VS Code](https://code.visualstudio.com/) with the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers).
3. Install [Node.js](https://nodejs.org/) on the **host** (Node 18+). This is the only host-side toolchain dependency beyond Docker and VS Code — the devcontainer's `initializeCommand` runs `node .devcontainer/ensure-host-config-dirs.cjs` to set up the bind-mount source directories before container create. If you already use Claude Code or another Node-based CLI on the host, you're already set.
4. Open the repo in VS Code → Command Palette → **Dev Containers: Reopen in Container**.
5. Wait for the first build (~3–6 minutes) and `postCreateCommand` to finish installing workspace dependencies.
6. Authenticate the three CLIs once — see [First-time CLI authentication](#first-time-cli-authentication) below.
## Windows 11 setup
### Windows-native (one-time setup, then "just works")
The host bind mounts use `${localEnv:HOME}/.claude` (and `.codex`, `.cursor`, `.ssh`, `.config/git`, `.config/gh`, `.gitconfig`). VS Code resolves `${localEnv:HOME}` by reading its own process env, and Windows doesn't set `HOME` by default — it uses `USERPROFILE`. So the bind mounts can't resolve until you tell Windows to also expose your profile as `HOME`.
The `initializeCommand` (`node .devcontainer/ensure-host-config-dirs.cjs`) handles this automatically:
1.**First time you Reopen in Container**, the script detects the missing `HOME`, runs `setx HOME "%USERPROFILE%"` (which writes to your user-level Windows env — no admin needed), prints a one-time setup banner, and exits.
2.**Close all VS Code windows** (File → Exit) and reopen. VS Code picks up the new `HOME` at startup.
3.**Reopen in Container again.** The script now sees `HOME=C:\Users\<you>`, skips the setup block, creates the bind-mount source dirs, and Docker brings the container up.
Subsequent rebuilds work normally with no extra steps. The `HOME` env var is set persistently in your Windows user environment, so it'll be there for every future VS Code session (and any other tool that wants `HOME`).
If you'd rather set it manually before opening the container:
```powershell
setxHOME"%USERPROFILE%"
# Close & reopen VS Code
```
### Known trade-offs of Windows-native vs WSL2
Windows-native works, but Docker Desktop's Windows bind-mount layer has rough edges that WSL2 avoids:
- **File watchers can miss events.** Vite / jest `--watch` running inside the container watching workspace files mounted from `D:\...` may miss changes — chokidar polling (`CHOKIDAR_USEPOLLING=true`) is the usual workaround.
- **`npm install` is 3-5× slower** through the Windows-to-Linux bind-mount translation than on a WSL2-native filesystem.
- **Permission edge cases.** The husky `.husky/_/h` EPERM class we hit earlier in this PR is specific to Windows-side bind mounts changing UID ownership between container runs. `post-create.sh` clears the cache defensively to keep this from being fatal, but it's still a real source of friction.
If you hit any of those and want to migrate to WSL2 later, the steps are below.
### WSL2 (faster, fewer edge cases)
To clone and open the repo inside WSL2:
```bash
# 1. Install WSL2 and a Linux distro if you haven't already.
wsl --install -d Ubuntu
# 2. Enter WSL.
wsl
# 3. Clone the repo inside your WSL2 home directory.
# 4. Launch VS Code from inside WSL — this opens VS Code attached to the WSL2
# filesystem, so `${localEnv:HOME}` resolves to the WSL user's home and
# subsequent "Reopen in Container" uses the WSL2-side path.
code .
```
Then run **Dev Containers: Reopen in Container**. The workspace will be bind-mounted from `\\wsl$\Ubuntu\home\<user>\GitNexus`, which is fast and gives reliable file-system events. **Make sure Docker Desktop's WSL integration is enabled** for your distro: Docker Desktop → Settings → Resources → WSL Integration → toggle on the distro you cloned into.
## macOS
Open the repo folder in VS Code → **Reopen in Container**. The image is multi-arch; on Apple Silicon you'll pull the `linux/arm64` variant automatically.
## Linux
Same as macOS — open in VS Code and reopen in container. `updateRemoteUserUID: true` (default) shifts the container's `node` user UID/GID to match your host user, so bind-mounted files stay writable without extra setup.
## How CLI state flows from your host
### AI CLIs (Claude Code, Codex, Cursor): copy-once from a read-only host stage + per-container credentials
The three AI CLIs use a **copy-from-read-only-stage topology**: the host's `~/.<cli>` folders (and `~/.claude-mem`) are mounted **read-only** at `/host/.<cli>`, and `post-create.sh` copies out of them into per-container named volumes. Credentials, identity, and single config files are copied on **every** create; the shareable subdirs (plugins, skills, agents, memory, commands, prompts, rules) are copied **once** on first create and then owned by the container. Nothing is bind-mounted read-write into the host's CLI config, so the container can never modify your host setup. Session sub-paths overlay the config volume via their own named volumes (Docker mount precedence — more specific path wins).
| **claude-mem store** | _named volume_`claude-mem-${devcontainerId}` | `/home/node/.claude-mem` | rw | claude-mem's SQLite DB + Chroma vector store; **seeded once** from `/host/.claude-mem`, then container-private — see note below |
| Host Claude state, read-only stage | `$HOME/.claude` | `/host/.claude` | **read-only** | `post-create.sh` reads credentials + identity from here on container-create |
| claude-mem store, read-only stage | `$HOME/.claude-mem` | `/host/.claude-mem` | **read-only** | `post-create.sh` seeds the claude-mem volume from here on first create |
| Host Codex state, read-only stage | `$HOME/.codex` | `/host/.codex` | **read-only** | Same purpose for Codex |
| Host Cursor state, read-only stage | `$HOME/.cursor` | `/host/.cursor` | **read-only** | Same purpose for Cursor |
| **Claude shareable subdirs** | _seeded into the config volume from_`$HOME/.claude/{plugins/marketplaces,plugins/cache,skills,agents,memory,commands}` | same under `/home/node/.claude/` | n/a (copy) | **Seed-once** copy from the read-only stage; container owns its copy after |
| **Codex shareable subdirs** | _seeded from_`$HOME/.codex/{plugins,prompts,memories,skills}` | same under `/home/node/.codex/` | n/a (copy) | **Seed-once** copy (whole `plugins/` dir — no path-bearing registry inside it) |
| **Cursor shareable subdirs** | _seeded from_`$HOME/.cursor/{plugins/marketplaces,plugins/local,rules,commands,agents,skills}` | same under `/home/node/.cursor/` | n/a (copy) | **Seed-once** copy of the Cursor 2.5 plugin/rules/commands surface |
**What gets seeded once from the host (copy, not bind):**
On the **first** container-create, `post-create.sh` copies each of these out of the read-only `/host/.<cli>` stage into the per-container config volume, then writes a `.devcontainer-shareable-seeded` marker. On every later rebuild the marker is present, so the copy is skipped and the container keeps whatever it has accumulated. A plugin/skill/agent you install **inside** the container persists across rebuilds; one you add on the **host** after first create won't appear in the container until you remove the config volume and rebuild (see [§ Rebuild / reset](#rebuild--reset)). Nothing here is writable back to the host — `/plugin marketplace add` inside the container installs into the container's own volume copy, not your host `~/.<cli>/plugins/`.
**Single config files are copied on container-create, not bind-mounted** — on Docker Desktop Windows a single-file bind is 9p while the named volume is ext4, and atomic config writes (`tmp` → rename onto target) trip EXDEV (this is what caused Codex's `config/batchWrite failed in TUI`). So these are synced from host on rebuild and the container rewrites its own copy until the next rebuild: `settings.json` + `$HOME/.claude.json` (Claude), `config.toml` (Codex), `cli-config.json` + `mcp.json` (Cursor). `hooks.json` (Cursor) is deliberately **not** synced — Cursor hooks execute shell commands, so sharing them would widen the supply-chain attack surface; add it yourself if you want it.
**Plugin registry files with absolute paths are translated, not copied verbatim** — Claude's `known_marketplaces.json` / `installed_plugins.json` / `plugin-catalog-cache.json` and Cursor's `installed_plugins.json` bake in `C:\Users\…` (Windows) or `/Users/…` (macOS) install paths. `post-create.sh` rewrites those to `/home/node/.<cli>/plugins/…` and writes the result into the named volume, so plugins resolve inside Linux instead of failing with `cache-miss`. This translation is **also seed-once per CLI** — it runs only for a CLI being seeded that create (`translate-plugin-registries.cjs claude cursor`), so it stays consistent with the seed-once `cache/` copy and won't overwrite a plugin you installed inside the container on a later rebuild. Codex needs no translation — its enablement registry is `config.toml` (git URLs + logical keys, no filesystem paths), so its whole `plugins/` dir is copied as-is.
**What stays per-container (in the named volume) and is synced from host on container-create:**
-`~/.claude/.claude.json` (Claude's identity-only file: `userID`, `oauthAccount`, migration tracking) — kept per-container so logging in via container doesn't overwrite host's stored identity
`post-create.sh` runs on every container-create, copies host's credentials into the volume if present, then container manages refresh from there. Sync is "always overwrite if host has the file, otherwise leave container alone". So:
- Host has credentials → container starts logged in.
- Host has no credentials → `claude login` / `codex login --device-auth` / `cursor-agent login` inside container; credentials stay in the named volume across rebuilds (volume is keyed by `${devcontainerId}`, stable for the workspace path).
**Why CLAUDE_CONFIG_DIR is intentionally NOT set:** Claude's default `~/.claude` matches the named-volume mount target, so the env var added no behavior — but setting it changed which file Claude reads `hasCompletedOnboarding` from. With it set, Claude reads `$CLAUDE_CONFIG_DIR/.claude.json` (the small identity-only file) and re-onboards every container; without it, Claude reads `$HOME/.claude.json` (copied from the read-only `/host/.claude.json` stage on container-create via `seed-claude-config.cjs`, with `hasCompletedOnboarding: true`).
**Host CLI config is protected from write-through.** The shareable dirs are copied out of a **read-only** stage into the container's own volume, so a compromised npm package in the workspace dep tree — running inside the container — **cannot** write a malicious agent, command, skill, or plugin back to `~/.claude/`, `~/.codex/`, or `~/.cursor/` on the host. The earlier design bind-mounted these read-write and accepted that write-through as the cost of live sync; this design closes it. An even earlier alternative (read-only stage + symlinks) made `/plugin marketplace add` inside the container fail with EROFS; copying into a writable volume avoids that, because the container writes to its own copy rather than a read-only mount. What a compromised dependency can still do is **read** the read-only host stages (`/host/.<cli>`, `/host/.claude-mem`) and the read-only credential mounts and exfiltrate them — there is [no egress firewall yet](#whats-not-included-yet). The cost of the copy model is **divergence**: host edits made after first create don't reach the container until you wipe the config volume and rebuild.
**Refresh-token divergence between rebuilds.** Container's credentials match host's at container-create time; after that, container manages its own refresh until the next rebuild. Anthropic rotates refresh tokens on every use, so an unattended container that hasn't talked to the API in weeks can hit a silent 401 if the host has refreshed since. Re-run `claude login` inside the container, or rebuild, to recover.
**claude-mem is seeded once, then container-private.** The [claude-mem](https://github.com/thedotmack/claude-mem) store (`$HOME/.claude-mem` — a multi-GB SQLite DB `claude-mem.db` + `-wal`/`-shm`, plus a Chroma vector store `chroma/chroma.sqlite3` and its HNSW index binaries) is the one shareable-looking folder that is **deliberately not a host bind**, for the same SQLite reason as sessions below: a multi-GB WAL database over the 9p/virtiofs bind risks unreliable `fcntl` locking and corruption — sharply so if claude-mem ran on the host and in the container against the same DB at once. So it gets its own per-container named volume (`claude-mem-${devcontainerId}`), and `post-create.sh`**seeds it once** from the read-only `/host/.claude-mem` stage _only when the volume has no DB yet_. The first container-create copies the host's store in (a one-time copy, possibly several GB); every later rebuild keeps whatever the container accumulated and skips the copy. The container's memory and the host's **diverge from that seed point** — writes do not flow back — which is the price of keeping SQLite off a shared bind. To re-seed from the host's current store, remove the volume (`docker volume rm claude-mem-<id>`) and rebuild. `ensure-host-config-dirs.cjs` creates an empty `~/.claude-mem` on hosts that never installed claude-mem, so the read-only stage bind always resolves; the seed then finds no DB and the container simply starts with empty memory.
### Session resume across container recreation
`claude --resume`, `codex resume`, and `cursor-agent resume` all read **local** transcript files. Those live _inside_ each CLI's config dir, which is a per-container named volume — so they already survive an ordinary **Rebuild Container**. What they did _not_ survive were the very things this README tells you to do: `docker volume rm <cli>-config-${devcontainerId}` to force a re-login or clear an `EACCES`, a `${devcontainerId}` change, or a full delete-and-recreate. Each of those drops the config volume and takes your session history with it.
So the resume/transcript directories get their **own** named volumes (mount group 6 in `devcontainer.json`), keyed like the `node_modules` volumes (`${localWorkspaceFolderBasename}-…-${devcontainerId}`) and mounted _over_ the config volume at the session sub-paths:
| `claude --resume` / `--continue` | `…-claude-sessions-…` → `~/.claude/projects` | `<encoded-cwd>/<uuid>.jsonl` transcripts + `sessions-index.json`. Container cwd is always `/workspace`, so only that slice is stored. Pure JSONL/JSON — no SQLite. |
| `codex resume` / `resume --last` | `…-codex-sessions-…` → `~/.codex/sessions` | `YYYY/MM/DD/rollout-*.jsonl`. The `state_5.sqlite` thread index stays on the config volume (a single WAL file we don't split out); when it's absent after a recreation, Codex rebuilds it from these rollouts on the next start (a one-time backfill). |
| `cursor-agent resume` / `ls` | `…-cursor-sessions-…` → `~/.cursor/chats`; `…-cursor-projects-…` → `~/.cursor/projects` | `chats/{hash}/{uuid}/store.db` (one SQLite db per session, each in its own dir) + `projects/.../agent-transcripts`. cursor-agent's layout is reverse-engineered, so treat this as best-effort. |
Because these are **separate** volumes from `<cli>-config-${devcontainerId}`, the re-login fix (`docker volume rm claude-config-…`) no longer destroys your sessions — that was the point.
**Survives:** Rebuild Container, Rebuild Without Cache, a full delete-and-recreate of the container, and the `docker volume rm <cli>-config-…` re-login / `EACCES` fix.
**Does _not_ survive** (same durability tier as the `node_modules` volumes): `docker volume prune`, a `${devcontainerId}` change (moving the checkout to a new path, or switching between Windows-native and WSL2), or moving to a new machine. To deliberately wipe sessions, remove the session volumes too — see [Rebuild / reset](#rebuild--reset). Two checkouts with the **same folder name** on one host would share session volumes only if they also share a `${devcontainerId}`; they don't, so they stay separate.
**First rebuild after adopting this, one-time:** if a container created _before_ these volumes existed already had sessions on the config volume (`~/.claude/projects`, `~/.codex/sessions`, …), the new empty session volume mounts _over_ that sub-path and **masks** the old content — same Docker-precedence shadowing described for plugins above. The old sessions are hidden, not deleted. To carry them forward once, copy them out of the config volume into the session volume; or just start fresh — new sessions land on the session volume from then on.
**Why sessions are container-private and not even seeded from the host.** The shareable config dirs are _seeded once_ from the host (you want your skills/agents/plugins in the container). Sessions are deliberately _not_ seeded and never touch the host, because a transcript can contain anything you pasted or the agent read — API keys, file contents, connection strings. Binding or copying them to/from the host would (a) spill that to host disk, (b) add a write-through surface a compromised dependency can reach (there's still [no egress firewall](#whats-not-included-yet)), and (c) leak _every other project's_ transcripts into the container (Codex `sessions/` and Cursor `chats/` aren't project-scoped). Container-private volumes avoid all three while still surviving recreation. And Claude/Codex transcripts embed the container cwd (`/workspace`), so even if you _did_ bind them to the host, the host CLI wouldn't natively `--resume` them — its encoded-cwd folder differs.
**Opt in to host-shared sessions anyway.** If you want transcripts visible/portable on the host and accept the trade-offs above, uncomment the host-bind block in `devcontainer.json` (just below the group-6 volumes) and add the matching source dirs to `ensure-host-config-dirs.cjs`'s `DIRS` so Docker can resolve the binds. That block scopes Claude to `/workspace`'s encoded subdir to limit the cross-project leak; the Codex and Cursor stores can't be scoped that way, so they expose every project's transcripts.
| `~/.config/gh` | `$HOME/.config/gh` | **copy → volume** | `gh` CLI auth (PR/issue create, checks) — seeded from your host login on create into a per-container volume; in-container `gh auth login` persists across rebuilds and never writes back to the host |
| `~/.docker` | `$HOME/.docker` | **read-only** | Container registry auth + buildx config (inert until you add Docker CLI via a Feature) |
**Why `ssh`/`aws`/`azure`/`docker` are read-only, and why `gh` is copied into a volume:**`ssh`/`aws`/`azure` are consumed read-only by their clients (the SSH client and the AWS/Azure SDKs only read their credential files), so a one-way mount loses nothing. `docker`_can_ write its own state (`docker login` / buildx write `config.json`), but a read-write host bind would let a compromised in-container dependency rewrite your host `~/.docker/config.json` (point a `credHelper` at an attacker-controlled binary) — a credential-takeover vector. The common case is _reading_ an existing host login, so `docker` stays **read-only**: registry pulls/pushes using your host creds work, only a `docker login` inside the container won't persist back. `gh` used to be read-only for the same reason, but that meant an in-container `gh auth login` had nowhere to write and silently failed. So `gh` now uses the **copy-into-volume** model (the same one the AI-CLI credentials use): the host `~/.config/gh` is a read-only _stage_ at `/host/.config/gh`, and `post-create.sh` copies `hosts.yml`/`config.yml` out of it into the per-container `gh-config` volume on create. The container gets a **writable** copy — `gh auth login` / `gh auth refresh` inside the container now work and persist across rebuilds — while the read-only stage guarantees nothing is ever written back to the host's token. If you want `docker` to behave the same way, give it the same treatment (a `/host/.docker` stage + a docker-config volume + a copy step in `post-create.sh`).
`~/.gitconfig` is **not** bind-mounted — VS Code's Dev Containers extension auto-copies the host's gitconfig into the container at attach time (this is built-in behavior, not something this devcontainer configures). The bind-mount approach conflicts with that auto-copy mechanism, so we let VS Code own it. The end result is the same: your host's `user.name` / `user.email` are available inside the container.
If a host source dir doesn't exist when the container is first created, the `initializeCommand` (`node .devcontainer/ensure-host-config-dirs.cjs`) creates it empty — so the bind mount always has a valid source.
### Per-CLI quirks worth knowing
- **Claude Code on macOS** stores credentials in the system Keychain, not in `~/.claude/.credentials.json`. The sync silently no-ops; run `claude login` inside the container once and the named volume persists it.
- **Codex on macOS / Linux with `cli_auth_credentials_store = "keyring"`** stores auth in the OS keyring (Keychain / Secret Service), so `~/.codex/auth.json` may not exist on host. Same fallback: `codex login --device-auth` inside the container.
- **Cursor CLI inside containers** has [known upstream auth issues](https://forum.cursor.com/t/cursor-agent-authentication-issue-inside-docker/143995) — even with a correctly-synced `cli-config.json`, you may need to re-run `cursor-agent login` inside the container.
- **Stale named volumes from old rebuilds can carry forward.** If you delete and re-create the same workspace, or if a prior container left interim state with a different `userID`, deleting the named volumes before rebuild guarantees a clean sync: `docker volume rm claude-config-${devcontainerId} codex-config-${devcontainerId} cursor-config-${devcontainerId}` (look them up with `docker volume ls | grep -config-`).
- **User-scope MCP servers with absolute host paths won't resolve in-container.** `~/.claude.json` (Claude), `~/.codex/config.toml` (Codex), and `~/.cursor/mcp.json` (Cursor) are copied from host on container-create, so their user-scope `mcpServers` entries come along. But an entry whose `command` is an absolute host path (`C:\tools\foo.exe`, `/usr/local/bin/foo`) points at a binary that doesn't exist in the container — that server silently fails to launch. Only registry/`npx`-based servers (like this repo's `.mcp.json`, which uses `npx -y gitnexus@latest mcp`) and remote/URL servers work unchanged. The path-translation pass only rewrites `*/.<cli>/plugins/*` registry paths, **not** arbitrary `mcpServers` command paths (there's no correct container target for a host-local binary). Install such MCP servers inside the container, or use `npx`/remote ones.
- **Host config is seeded once per devcontainer, then diverges — this now applies to everything.** A `mcpServers` entry, setting, plugin, skill, agent, or command you add **on the host after** the container was created is not visible in the container until you remove the config volume and rebuild. Single config files (`mcpServers`, `settings.json`, …) are copy-on-create; the shareable dirs (plugins/skills/agents/memory/commands/prompts/rules) are copy-on-**first**-create (they persist across ordinary rebuilds and aren't even re-copied). Both diverge from the host after their copy. To pull host-side changes in, wipe the relevant volume and rebuild (see [§ Rebuild / reset](#rebuild--reset)).
- **Plugins/skills/agents installed in-container persist; they do not reach the host.** A `/plugin marketplace add` (or `codex plugin add`, or a new skill/agent) inside the container writes to the container's own config volume and survives ordinary rebuilds. It never appears on the host — the host dirs are read-only sources, not bind targets. To get a plugin onto the host, install it on the host (then wipe + rebuild to seed it into the container).
- **No cross-checkout plugin contention.** Because each container copies plugins into its own per-`${devcontainerId}` volume rather than sharing one host bind source, two containers (or checkouts) installing plugins at the same time no longer interleave git clones/extractions against a shared host dir. Each writes only its own copy.
### What you still don't have inside the container
These are commonly-needed CLIs that aren't installed by default — adding them would be follow-up work, not in this PR's scope:
- **Docker CLI** (for `docker push` / `docker build` from inside the container). Add via `ghcr.io/devcontainers/features/docker-outside-of-docker:1` to the `features` block — `~/.docker/` is already mounted **read-only**, so your host `docker login` state works immediately for pulls/pushes; an in-container `docker login` won't persist to the host (drop `,readonly` on that mount if you need it to).
- **AWS CLI / Azure CLI / gcloud / kubectl** — same pattern: add the matching Feature, the host config dirs already flow through.
- **Private npm registry auth** (`~/.npmrc`) — you don't have a global one on this host. If you ever start using private packages, add `source=${localEnv:HOME}/.npmrc,target=/home/node/.npmrc,type=bind,readonly` to the mounts.
That means:
- **Authentication is shared.** If you're already logged in on the host (`claude login`, `codex login`, `cursor-agent login`, `gh auth login`), you're already logged in inside the container. No second login step.
- **Plugins, skills, agents, memory, and commands are seeded from the host once, then container-private.** On first create the container copies your host's plugins/skills/agents/memory/commands (and Codex prompts/memories, Cursor rules) into its own volume. After that they're independent: install or edit inside the container and it stays in the container (persists across rebuilds); add a plugin or agent on the host and the container won't see it until you wipe the config volume and rebuild. Nothing the container does reaches the host. (`settings.json` and the user-scope `~/.claude.json` are copy-on-create the same way; `~/.claude/projects/` is container-local by design.)
- **Git identity comes from the host.** Commits from inside the container use your host's `user.name` / `user.email` — VS Code's Dev Containers extension auto-copies your `~/.gitconfig` into the container at attach time. Any XDG-style config under `~/.config/git/` flows through via the read-only bind mount. To change git identity, edit `~/.gitconfig` on the host (container-side `git config --global` writes to a container-local file that's discarded on rebuild).
- **SSH keys flow through (read-only).** Push over SSH remotes and SSH commit signing work inside the container using your host keys. The mount is read-only so container code can't exfiltrate or modify private keys — agent-perspective, this means you get git operations but the keys stay vendor-side.
- **`gh` auth is shared, and in-container logins persist.** If you're logged in on the host, `gh pr create`, `gh pr checks`, `gh issue create` work inside the container without re-authenticating. If you're not, run `gh auth login` inside the container once — because `gh` config lives in a writable per-container volume (seeded from the host stage), that login persists across rebuilds and never touches the host's token.
- **No per-workspace duplication.** All your devcontainers across all your projects see the same host CLI state, just like all your host shells do.
The bind mount source directories are guaranteed to exist by the `initializeCommand` (`node .devcontainer/ensure-host-config-dirs.cjs`), which runs on the host before container create. It's a Node script (not a shell one-liner) so the same command works on Windows `cmd.exe` and POSIX shells. It creates the top-level bind-mount source dirs — `~/.claude`, `~/.codex`, `~/.cursor`, `~/.claude-mem`, plus `~/.ssh`, `~/.docker`, `~/.aws`, `~/.azure`, `~/.config/{gh,git}`. It deliberately does **not** pre-create the shareable subdirs (skills/agents/plugins/…): those are no longer bind sources (they're copied out of the whole-`~/.<cli>` read-only stage), and pre-creating empty ones would needlessly write into the host of someone who never used that CLI.
### Trust boundary, concretely
Host and container share a single trust boundary by design — fine for personal-dev, but the consequence is concrete. Any malicious npm package or `postinstall` script in the workspace dep tree, running inside the container, has direct **read** access to:
- **Host AI CLI state** — the read-only stage at `/host/.claude`, `/host/.codex`, `/host/.cursor`, `/host/.claude-mem`, which exposes your **entire** host `~/.<cli>` tree (credentials, identity, AND the shareable skills/agents/plugins/memory/commands) for _reading_. The container copies what it needs out of this stage; a compromised dep can read all of it. It is read-only, so none of it can be written back
- The **container's own credential snapshots** at `/home/node/.claude/.credentials.json` etc. (copied from host on container-create)
-`~/.claude/memory/` / per-project memory (which may contain user-stored secrets if you've used the `/remember` skill)
- The **current container's own session transcripts** (`~/.claude/projects`, `~/.codex/sessions`, `~/.cursor/chats`/`projects` — the group-6 volumes), which can hold anything pasted into or read during a session. These are container-private (see one-way note below), so this is read access to _this_ container's sessions only, not the host's or other projects'
- Your **`gh` token** (`~/.config/gh`)
- Your **SSH private keys** (`~/.ssh/`)
- Docker registry tokens in **`~/.docker/config.json`** (if you've `docker login`-ed)
- AWS/Azure CLI credentials if you've populated `~/.aws/` or `~/.azure/`
It does **not** have write-through to the host's CLI config. The shareable dirs are copied out of the read-only stage into the container's own volume, so a compromised in-container dep **cannot** write into your host `~/.claude/{plugins,agents,skills,commands,memory}/`, `~/.codex/{plugins,prompts,memories,skills}/`, or `~/.cursor/{plugins,rules,commands,agents,skills}/`. The persistence vector earlier versions had — drop a malicious auto-loaded agent/command/skill/rule onto the host, have it run in your next **host** session — is closed: there is no writable path from the container to those host folders. (Cursor's `hooks.json` is still additionally withheld from even the _container's_ copy, because hooks fire without an agent invoking them.) The boundary is now one-way for **all** of the host CLI config, not just credentials.
**What stays one-way (genuinely protected):** everything. Credentials never flow back to host — `.credentials.json` / `auth.json` / `cli-config.json` live only in the per-container named volumes, and the `/host/.<cli>` stage they're copied from is mounted **read-only**, so the snapshot can't be overwritten back. The shareable AI-CLI dirs (skills/agents/plugins/memory/commands/prompts/rules) are now copy-on-create from that same read-only stage, so they have the one-way property too — readable for the copy, never writable back. `~/.ssh`, `~/.config/git`, `~/.aws`, `~/.azure`, and **`~/.docker`** are read-only binds with the same property — a compromised dep can _read_ your registry tokens but cannot _rewrite_ them to hijack your future host auth. **`~/.config/gh`** is now a read-only _stage_ copied into a per-container volume, so it keeps that same one-way property: the container reads it once to seed its own writable copy, and the read-only stage means an in-container `gh auth login` can never overwrite your host token. **Session transcripts** live in per-workspace named volumes (mount group 6) and are never seeded from or written back to the host, and the container can't see any _other_ project's transcripts. The opt-in host-bind block in `devcontainer.json` reverses that for sessions only — enable it only if you accept transcripts on host disk; see [Session resume across container recreation](#session-resume-across-container-recreation).
**The egress firewall is the key compensating control that is still missing.** It's deferred (see "What's not included (yet)" below), so a compromised package currently has unrestricted outbound network to exfiltrate anything in the read list above. Until it lands, treat that read surface as exposed to any code you run in the container — don't use this devcontainer on a machine whose host credentials you couldn't afford to rotate. The isolated-volume setup below removes host AI-CLI config/credentials from that surface entirely.
**If a workspace dep is ever found compromised**, rotate credentials at the vendor side — local file deletion is insufficient because tokens may have already left:
- Anthropic: [console.anthropic.com → Settings → Keys](https://console.anthropic.com/settings/keys), revoke the OAuth session under Account
- OpenAI / Codex: [platform.openai.com/api-keys](https://platform.openai.com/api-keys), revoke session under Profile
- GitHub: `gh auth refresh` or revoke the token at github.com/settings/tokens
For high-trust enterprise environments where the container should not even be able to **read** host CLI state, remove the three read-only stage binds (`/host/.claude`, `/host/.codex`, `/host/.cursor`) — plus `/host/.claude-mem` and `/host/.claude.json` — from `.devcontainer/devcontainer.json`. With no stage to copy from, `post-create.sh`'s seed and credential-sync steps quietly do nothing (their `[ -f ]` / `[ -d ]` guards), and each devcontainer starts with empty, fully isolated config and credentials (Anthropic's reference pattern). You give up seeding your host setup into the container in exchange for removing host config/credentials from the container's read surface entirely; log in inside each container instead.
## First-time CLI authentication
Each CLI works either way:
- **Log in on host first** → the container picks it up automatically on the next rebuild (`sync_from_host` copies the credential file into the named volume during `post-create.sh`). Host stays the source of truth.
- **Log in inside the container** → credentials write to the named volume. They persist across ordinary rebuilds (volume is keyed by `${devcontainerId}`, which is stable for a given workspace folder). The host's credentials are untouched.
You can mix and match per-CLI. A common setup is "Claude logged in on host, Codex/Cursor logged in inside container".
### Claude Code
```bash
claude login
```
Opens a browser auth flow. VS Code's port forwarding handles the OAuth callback automatically. After auth, `~/.claude/` is populated and visible from both host and container. The `DISABLE_AUTOUPDATER=1` env var prevents the in-container CLI from auto-updating — rebuild the container to pick up a newer Claude Code.
### OpenAI Codex CLI
```bash
codex login --device-auth
```
The device-code flow prints a URL and a one-time code. Visit the URL on your host browser, paste the code, and the CLI authenticates without needing a callback listener — this is the most reliable path inside containers. Credentials land in `~/.codex/auth.json` (shared with host).
`codex login` (browser-callback variant) also works but can be flaky in some headless contexts; prefer `--device-auth`.
### Cursor CLI
```bash
cursor-agent login
```
Opens a browser auth flow; VS Code's port forwarding handles the callback. Credentials persist in `~/.cursor/cli-config.json` (shared with host).
Verify any time with `cursor-agent status`.
## Alternative: API key authentication (CI / headless)
For non-interactive use (CI runners, automated scripts), all three CLIs accept API keys via env vars:
These env vars are intentionally **not** injected into the container from the host. `${localEnv:VAR}` resolves an unset host variable to an empty string, and some CLIs (Cursor in particular) treat a set-but-empty key as "use this key" rather than "fall back to stored login" — which would silently break the login flow for everyone who hasn't pre-set the host var.
To use an API key inside the container, export it in your terminal session:
```bash
exportANTHROPIC_API_KEY=sk-ant-...
# or OPENAI_API_KEY, or CURSOR_API_KEY
```
For persistence across container shells, carry the export via your VS Code [dotfiles repository](https://code.visualstudio.com/docs/devcontainers/containers#_personalizing-with-dotfile-repositories). VS Code clones the dotfiles repo into the container on attach and runs your install command, so the export lands in `~/.bashrc` / `~/.zshrc` per your own setup — and your API keys stay out of this repo's committed `devcontainer.json`.
A non-empty API key env var takes precedence over stored login credentials for each CLI.
VS Code's Ports panel shows forwarded ports once their listener starts.
## Known gotchas
- **LadybugDB integration tests may fail in containers** (file-locking, `AGENTS.md` § Testing). Default to `npm run test:unit` inside the container; run integration tests on the host. Tracking issue: documented as a known limitation.
- **Single-writer LadybugDB constraint** (`GUARDRAILS.md` § LadybugDB lock). Don't run `gitnexus analyze` on the host and inside the container against the same `.gitnexus/` directory simultaneously — the second writer will get `database busy`.
- **Native grammar builds add ~30s to first install.** Tree-sitter Dart/Proto/Swift grammars build during `gitnexus`'s `postinstall`. To skip them (loses parsing for those three languages), set `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` in your shell or add it to `remoteEnv` and rebuild.
- **`tree-sitter-kotlin` warnings on install** are expected (per `AGENTS.md`). Ignore them.
- **`.mcp.json` works inside the container**: `npx -y gitnexus@latest mcp` resolves cleanly because npm registry is reachable and the workspace bind mount exposes the same `.mcp.json` the host sees.
- **Husky pre-commit fires inside the container** without extra setup. The root `npm install` (run automatically in `postCreateCommand`) installs the hook via `package.json``prepare`.
## Rebuild / reset
- **Rebuild Container** (Command Palette) — re-runs the Dockerfile build and `postCreateCommand` against the existing named volumes (auth, history, **and sessions** persist).
- **Rebuild Container Without Cache** — fresh image layers, same volumes.
- **To force a re-login / clear an `EACCES`** — remove the per-container _config_ volumes and rebuild. As of the session-volume change this **no longer drops your `--resume` history** (sessions are on separate volumes — see [Session resume](#session-resume-across-container-recreation)):
```bash
docker volume ls | grep -- -config- # the credential / identity volumes
⚠️ Since the shareable dirs are now seeded into the config volume (not bind-mounted), wiping `<cli>-config` **also discards any plugin/skill/agent/command you installed _inside_ the container** and re-seeds those dirs from the host on the next rebuild. That is the intended way to pull host-side config changes in, but if you have in-container-only plugins you want to keep, reinstall them after the rebuild (or install them on the host first so the re-seed brings them along).
- **To also wipe session history** (a true clean slate) — remove the session volumes too (`<name>` is your workspace folder name):
```bash
docker volume ls | grep -E -- '-(sessions|cursor-projects)-' # the group-6 volumes
- **To re-seed claude-mem from the host** (the container's memory has diverged and you want the host's current store back) — remove the claude-mem volume and rebuild; `post-create.sh` copies the host store in again on the next create:
```bash
docker volume rm claude-mem-<id>
```
## Bumping CLI versions
Bump the version pins in `.devcontainer/devcontainer.json` `build.args` and rebuild — all three are real, fail-loud pins. Claude Code installs via `npm install -g @anthropic-ai/claude-code@${CLAUDE_CODE_VERSION}` and Codex via `npm install -g @openai/codex@${CODEX_VERSION}`. **Cursor is pinned too:** bump `CURSOR_VERSION` **and** both `CURSOR_SHA256_X64` / `CURSOR_SHA256_ARM64` together — the Dockerfile downloads the pinned `downloads.cursor.com/lab/<version>/linux/<arch>/agent-cli-package.tar.gz` artifact directly (no remote install script) and fails the build on a sha256 mismatch. Re-hash each arch with `curl -fSL <url> | sha256sum`. To stop Cursor from auto-updating in the running container, don't call `cursor-agent update`.
## What's not included (yet)
- **Egress firewall — the most important hardening still outstanding.** The original plan included an opt-in iptables/ipset firewall adapted from Anthropic's reference devcontainer. It was deferred to a follow-up PR — `runArgs` is static in `devcontainer.json`, so toggling NET_ADMIN/NET_RAW capabilities cleanly requires either a separate `devcontainer-firewall.json` profile or an `initializeCommand`-generated overlay. Until it lands, the read surface in [§ Trust boundary](#trust-boundary-concretely) has no network containment — anything readable can be exfiltrated. Track at the project's issue tracker if you need this.
- **Codespaces tuning.** The current config works in Codespaces incidentally (no privileged capabilities, no host-mount assumptions), but isn't actively tested there.
- **Playwright e2e support.** `gitnexus-web`'s `npm run test:e2e` needs Chromium libs that the base image doesn't ship. Use the host for e2e until a Playwright layer is added.

If `analyze` reports a worker parse timeout on a large or unusual repository, it keeps running and falls back safely. To give slow worker jobs more time, use `gitnexus analyze --worker-timeout 60` or set `GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS=60000`. For very large files, `GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES` controls the worker job byte budget.
#### Embeddings node limit
`gitnexus analyze --embeddings` generates semantic search vectors with a default 50,000-node safety cap to protect memory on large repositories. Override the cap when you know the host has enough memory for a larger graph, or disable it entirely for a one-off full embeddings run.
```bash
# Generate embeddings with the default 50,000 node safety cap
gitnexus analyze --embeddings
# Disable the safety cap entirely
gitnexus analyze --embeddings 0
# Use a custom cap
gitnexus analyze --embeddings 100000
```
If embeddings are skipped on a large repository, the indexed graph likely exceeds the default safety cap. Re-run with `gitnexus analyze --embeddings 0` to remove the cap, or `gitnexus analyze --embeddings <n>` to choose a higher limit while still keeping memory bounded.

## Performance metrics (targets)
## Scope-resolution parity
Set targets to match team expectations, then tune to this repo’s CI reality:
Migrated languages (listed in `MIGRATED_LANGUAGES` in `src/core/ingestion/registry-primary-flag.ts`) are tested in both legacy and registry-primary modes on every PR.
Both must pass. Known legacy gaps are listed in `LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES` in `test/integration/resolvers/helpers.ts` and are automatically skipped in legacy mode.
Adding a language to `MIGRATED_LANGUAGES` automatically enrolls it in parity — no workflow or config edit needed. The test file must exist at `test/integration/resolvers/<slug>.test.ts`.
Run parity locally: `cd gitnexus && npm run test:parity`
Run for a single language: `cd gitnexus && npx tsx scripts/run-parity.ts --language python`
## Cross-platform testing
Windows and macOS CI runs only the platform-sensitive test subset (~50 files out of 373). The full suite runs on Ubuntu.
The subset is defined in `gitnexus/scripts/cross-platform-tests.ts` and includes:
| `ci-tests.yml` | ubuntu/coverage, cross-platform (Win/Mac), packaged-install-smoke | Full suite + coverage on Ubuntu; platform-sensitive subset on Win/Mac |
| `ci-scope-parity.yml` | discover, parity | Scope-resolution parity for all migrated languages |
- **`ci-e2e.yml`** — Playwright E2E tests, gated on `gitnexus-web/**` changes
Local checks before pushing:
```bash
cd gitnexus && npx tsc --noEmit && npm test
cd ../gitnexus-web && npx tsc -b --noEmit && npm test
```
Or rely on the pre-commit hook which runs these automatically for staged files.

For staged releases or UI betas: deploy to a staging environment, collect structured feedback, watch errors and latency, then iterate before a wider release.
GitNexus indexes COBOL codebases using a **regex-only extraction** strategy, bypassing tree-sitter entirely. This document explains why, how the pipeline works, and links to detailed sub-documents.
## Why Regex-Only?
The tree-sitter-cobol grammar (v0.0.1) has three critical limitations that make it unusable for production indexing:
| Issue | Impact | Severity |
|-------|--------|----------|
| External scanner hangs on ~5% of files | No timeout mechanism exists for the C scanner; the process blocks indefinitely | **Blocking** |
| Only ~15% of paragraph headers detected | Most procedure-division paragraphs are invisible to the grammar | High |
| Patch markers in cols 1-6 cause parse errors | Enterprise COBOL uses non-standard sequence area content (e.g., `mzADD`, `estero`, `#FIX`) | High |
Because the external scanner hang cannot be interrupted (there is no `setTimeoutMicros` equivalent for tree-sitter), using tree-sitter-cobol would hang the indexing pipeline on a non-trivial fraction of real-world files.
The regex-only approach provides:
- **Speed**: ~1ms per file average extraction time
- **Reliability**: zero hangs, zero crashes across 13,000+ files
- **Coverage**: captures all critical symbols -- program name, paragraphs, sections, CALL, PERFORM, COPY, data items (01-77, 88-level), file declarations, FD entries, EXEC SQL/CICS blocks, ENTRY points, and MOVE statements

## COBOL vs Tree-Sitter Languages
| Feature | COBOL (Regex) | Tree-Sitter Languages |
The COPY statement is COBOL's include mechanism -- analogous to `#include` in C or `import` in modern languages. GitNexus expands COPY statements **before** regex extraction so that symbols defined inside copybooks (data items, paragraphs, etc.) are visible in the program's extracted graph.
## Supported Syntax
### Basic COPY
```cobol
COPY CPSESP.
COPY "WORKGRID.CPY".
```
Inlines the content of the named copybook, replacing the COPY line(s).
Pipeline->>Pipeline: Replace file content with expanded content
end
```
The return type `CopyExpansionResult` contains `expandedContent` and `copyResolutions`. The `expansionDepth` field has been removed from the return type (it was unused by callers).
COPY statement line numbers in `CopyResolution` are 1-based (consistent with the preprocessor's line numbering). The splice operation that replaces COPY lines with expanded content adjusts for 0-based array indexing internally.
## Cycle Detection
Circular COPY references (e.g., copybook A includes copybook B which includes copybook A) are detected and handled:
1. Each expansion chain maintains a `visited` set of resolved copybook paths
2. If a copybook path is already in the visited set, the expansion is skipped
3. A `warnedCircular` set (internal to `expandCopies()`, not a parameter) deduplicates warning messages within a single file expansion
Known circular copybooks in PROJECT-NAME: `ANAZI`, `ANDIP`, `QDIPE` (self-referential includes).
## Max Depth
Nested COPY expansion is limited to **10 levels** (`DEFAULT_MAX_DEPTH`). If a COPY chain exceeds this depth, a warning is logged and the remaining COPY statements are left unexpanded.
## Max Total Expansions
A breadth amplification guard caps the total number of COPY expansions across all branches within a single file to **500** (`MAX_TOTAL_EXPANSIONS`). This prevents exponential blowup from diamond-shaped COPY graphs where N copybooks each include N other copybooks. Once the limit is reached, further COPY statements in that file are left unexpanded and a single warning is logged.
## REPLACING Application Detail
The REPLACING engine works by scanning all COBOL identifiers (matching `\b[A-Z][A-Z0-9-]*\b`) in the copybook content and applying each replacement rule:
```
Original copybook content:
05 ESP-NAME PIC X(30).
05 ESP-CODE PIC X(10).
05 KPSESPL-FLAG PIC X(01).
After REPLACING LEADING "ESP-" BY "LK-ESP-" LEADING "KPSESPL" BY "LK-KPSESPL":
05 LK-ESP-NAME PIC X(30).
05 LK-ESP-CODE PIC X(10).
05 LK-KPSESPL-FLAG PIC X(01).
```
For LEADING replacements, the engine checks if each identifier starts with the `from` prefix (case-insensitive) and replaces only the prefix portion, preserving the rest of the identifier.
For TRAILING replacements, the same logic applies to suffixes.
For EXACT replacements, only identifiers that match the `from` value exactly (case-insensitive) are replaced.
## Copybook Resolution
The resolver tries multiple strategies to match a COPY target name to a copybook file:
1.**Exact match**: `COPY CPSESP` resolves to copybook named `CPSESP`
2.**Strip extension**: `COPY WORKGRID.CPY` strips `.CPY` and resolves to `WORKGRID`
3.**Add extension**: `COPY CPSESP` tries `CPSESP.CPY` and `CPSESP.COPY`
If no match is found, the COPY statement is left in place (unexpanded) and a resolution record with `resolvedPath: null` is created.
## Pipeline Integration
The expansion runs **per chunk**, after file content is read but before dispatch to worker threads:
1. All copybook files are read upfront (they are typically small, collectively under 100MB)
2. Per chunk, the copybook map is merged with chunk content (in case a chunk contains copybooks)
3. Only programs (not copybooks themselves) undergo expansion
4. The expanded content replaces the original content in-place before worker dispatch
## Inline Comment Handling
The copy expander's `stripInlineComment()` helper is quote-aware: pipe characters (`|`) inside single- or double-quoted strings are preserved. This matches the same quote-aware logic used by the preprocessor.
The stack maintains items where each entry's level is strictly less than the next. When a new item arrives with a level <= the top of stack, items are popped until the stack top has a smaller level. A `CONTAINS` edge is created from the stack top to the new item.
For 88-level condition names, the parent is the immediately preceding non-88 data item (found by scanning backwards).
A maximum of **500 data items per file** (`MAX_DATA_ITEMS_PER_FILE`) are processed. Some COBOL programs (especially after COPY expansion) can have 10,000+ data items, which would cause graph bloat and push the V8 relationship Map past its 16.7M entry limit across thousands of files.
The cap applies after extraction: the first 500 items in source order are kept. Since 01-level records appear first, critical top-level structure is preserved.
## EXEC SQL
EXEC SQL blocks are accumulated across lines between `EXEC SQL` and `END-EXEC`, then parsed as a unit.
### Operation Classification
The first SQL keyword determines the operation:
| First Keyword | Operation |
|---------------|-----------|
| `SELECT` | SELECT |
| `INSERT` | INSERT |
| `UPDATE` | UPDATE |
| `DELETE` | DELETE |
| `DECLARE` | DECLARE |
| `OPEN` | OPEN |
| `CLOSE` | CLOSE |
| `FETCH` | FETCH |
| *(anything else)* | OTHER |
### Table Extraction
Tables are extracted from SQL clauses:
| Clause Pattern | Example |
|----------------|---------|
| `FROM <table>` | `SELECT * FROM EMPLOYEES` |
| `INSERT INTO <table>` | `INSERT INTO EMPLOYEES` |
| `UPDATE <table>` | `UPDATE EMPLOYEES SET ...` |
| `JOIN <table>` | `LEFT JOIN DEPARTMENTS ON ...` |
Note: The `INTO` pattern is restricted to `INSERT INTO` to avoid false positives from `FETCH ... INTO :host-var` and `SELECT ... INTO :host-var` statements, where `INTO` introduces host variables rather than table names.
This distinction allows queries to find bulk field-by-field moves separately from simple variable assignments.
## GO TO DEPENDING ON
The `GO TO` statement with multiple targets and a `DEPENDING ON` clause is a computed branch:
```cobol
GOTOPARA-1PARA-2PARA-3
DEPENDINGONWK-SELECTOR.
```
All target paragraph names are extracted and emitted as separate `gotos` entries. Each target produces a `CALLS` edge in the graph (same semantics as PERFORM). The `DEPENDING ON` variable is not currently tracked as a data-flow dependency.
## SORT INPUT/OUTPUT PROCEDURE
SORT and MERGE statements can specify procedural entry points instead of file-based I/O:
```cobol
SORTSORT-FILEONASCENDINGKEYSORT-KEY
INPUTPROCEDUREISPREPARE-INPUT
OUTPUTPROCEDUREISFORMAT-OUTPUT.
```
`INPUT PROCEDURE IS` and `OUTPUT PROCEDURE IS` targets are extracted as control-flow targets (same as PERFORM). They produce `performs` entries and corresponding `CALLS` edges in the graph.
## Fixed-Format Literal Continuation
In fixed-format COBOL, string literals can span multiple lines using the continuation indicator (`-` in column 7). When a continuation line starts with a quote character, the extractor joins it with the predecessor by removing the trailing quote from the previous line and the opening quote from the continuation:
```
Line N: MOVE "THIS IS A LONG STRI
Line N+1 (cont): - "NG VALUE" TO WK-FIELD.
Merged: MOVE "THIS IS A LONG STRING VALUE" TO WK-FIELD.
```
The trailing `"` on line N and the opening `"` on line N+1 are both removed, producing a seamless literal. If no matching quote is found on the predecessor line, the continuation is appended as-is.
## Source Files
-`gitnexus/src/core/ingestion/cobol-preprocessor.ts` -- All extraction logic, clause parsers, EXEC block parsers
GitNexus detects COBOL files through two mechanisms: extension-based mapping and directory-based override for extensionless files. This document covers both, plus the copybook/program classification logic.
| `.open` / `.OPEN` | Copybook | File OPEN fragment |
| `.close` / `.CLOSE` | Copybook | File CLOSE fragment |
| `.ini` / `.INI` | Copybook | Initialization fragment |
| `.def` / `.DEF` | Copybook | Definition fragment |
All extension matching is case-sensitive in `getLanguageFromFilename` (the extensions above are matched as written, including uppercase variants like `.GNM`).
Many enterprise COBOL repositories use extensionless files -- the filename alone identifies the program (e.g., `s/BGTABFL` is the source for program `BGTABFL`). GitNexus handles this via the `GITNEXUS_COBOL_DIRS` environment variable.
### Configuration
Set `GITNEXUS_COBOL_DIRS` to a comma-separated list of directory names:
```bash
# Files in s/, c/, and wfproc/ directories (at any depth) are treated as COBOL
exportGITNEXUS_COBOL_DIRS=s,c,wfproc
```
The matching is **case-insensitive** and checks all path segments:
The path segment check splits the full path on `/` and tests each segment against the cached set.
## Copybook vs Program Classification
After a file is identified as COBOL, it must be classified as either a **program** (to be parsed for symbols) or a **copybook** (to be loaded into the copybook map for COPY expansion).
### Classification Rules
A COBOL file is classified as a **copybook** if ANY of these conditions is true:
1. It has a recognized copybook extension (`.cpy`, `.copy`, `.gnm`, `.fd`, `.wrk`, `.sel`, `.open`, `.close`, `.ini`, `.def`)
2. It is an extensionless file whose path contains a directory segment matching one of: `c`, `copy`, `copybooks`, `copylib`, `cpy`
A file is classified as a **program** if:
1. It has a program extension (`.cbl`, `.cob`, `.cobol`), OR
2. It is extensionless and does NOT match any copybook directory pattern
### Copybook Name Resolution
Copybook names are derived from the filename:
- Strip the extension (if any)
- Convert to uppercase
Examples:
-`c/CPSESP` -- name: `CPSESP`
-`copy/workgrid.cpy` -- name: `WORKGRID`
-`c/ANAZI.GNM` -- name: `ANAZI`
This name is used to resolve `COPY CPSESP.` statements during expansion.
This document describes the graph nodes and edges that GitNexus creates for COBOL codebases. The COBOL graph model is richer than most tree-sitter languages because it captures domain-specific constructs: file declarations, FD entries, data hierarchies, SQL tables, CICS maps, and cross-program contracts.

## Node Types
| Node Type | COBOL Concept | Created From | Example |
The worker pool splits each worker's chunk into sub-batches to bound peak memory per `postMessage` serialization. COBOL repos use a smaller sub-batch size than the default:
| Per sub-batch timeout | 120s | 120s (configurable) |
**Why 200?** COBOL regex extraction + preprocessing takes ~1ms per file on average, but with COPY expansion and deep indexing the effective time is ~150ms per file. At sub-batch size 1500, that would be ~225s per sub-batch, exceeding the 120s timeout.
COBOL mode is activated automatically when `GITNEXUS_COBOL_DIRS` is set:
Workers default to `min(8, cpus - 1)`. For COBOL repos, this is usually sufficient since regex extraction is CPU-bound but fast. The bottleneck is typically KuzuDB write, not extraction.
For COBOL-only repos, worker startup is faster because tree-sitter native modules are loaded lazily (skipped entirely if only COBOL files are present).
## Data Item Cap
### Configuration
```typescript
constMAX_DATA_ITEMS_PER_FILE=500;
```
This constant appears in both `parse-worker.ts` (worker path) and `parsing-processor.ts` (sequential fallback).
### Rationale
Some COBOL programs, especially after COPY expansion, can have 10,000+ data items. At that scale:
- The in-memory relationship Map (for CONTAINS, REDEFINES, etc.) approaches the V8 16.7M entry limit across thousands of files
- KuzuDB write time increases linearly with edge count
- Most deep-nested items (level 20+) are rarely queried individually
### Impact
The cap truncates data items beyond the 500th in source order. Since 01-level Records appear first in COBOL source, the cap preserves:
- All 01-level record definitions
- The most important 02-49 level items (those closest to the record root)
- 88-level conditions associated with early items
To increase the cap for specific needs, modify the `MAX_DATA_ITEMS_PER_FILE` constant in both files.
## Memory Management
### COPY Expansion Breadth Guard
A per-file `MAX_TOTAL_EXPANSIONS = 500` limit prevents exponential blowup from diamond-shaped COPY graphs (e.g., N copybooks each containing N COPY statements). Once the limit is reached, further COPY statements in that file are left unexpanded. See [copy-expansion.md](copy-expansion.md) for details.
### COPY Expansion Memory
All copybook content is loaded upfront into a Map before chunk processing begins. For PROJECT-NAME:
- 2,976 copybooks, typically under 100MB total
- The Map is shared (read-only) across chunk iterations
- Per-chunk, the copybook map is merged with chunk file content (in case a chunk contains copybooks not in the pre-loaded set)
- After all chunks are processed, the copybook map is freed (`cobolCopybookContents = undefined`)
### Chunk Budget
Source files are grouped into chunks of max 20MB (`CHUNK_BYTE_BUDGET`). Each chunk's lifecycle:
This ensures only ~20MB of source + ~200-400MB of working memory (ASTs, extracted records, serialization) is active at any time.
### Shared Warning Deduplication
The `warnedCircular` set (used by the COPY expansion engine) is shared across all files in a chunk. This prevents the same circular copybook warning (e.g., `ANAZI includes itself`) from being logged thousands of times.
| tree-sitter-cobol hangs on ~5% of files | Cannot use tree-sitter for COBOL | Regex-only extraction (current approach) |
| Data item cap (500/file) | May miss deeply nested items in large programs | Increase `MAX_DATA_ITEMS_PER_FILE` in source |
| Circular copybooks (ANAZI, ANDIP, QDIPE) | Self-referential includes cannot be expanded | Detected and skipped with warning |
| wfproc/ files may not be pure COBOL | Workflow files may produce extraction noise | Exclude `wfproc` from `GITNEXUS_COBOL_DIRS` if problematic |
| No MOVE DATA_FLOW edges yet | Data flow between variables not in graph | Reserved for future release |
| Continuation line handling | Some complex multi-line continuations (especially in string literals spanning 3+ lines) may not merge correctly | Known edge case; affects <0.1% of lines |
| Single-line EXEC blocks | `EXEC SQL SELECT ... END-EXEC` on one line is handled, but pathological nesting is not | Extremely rare in practice |
| Extension case sensitivity | `.GNM` and `.gnm` are matched differently | Use the exact case from the codebase |
## Troubleshooting
### "COPY expansion failed"
```
[pipeline] COPY expansion failed for s/BGTABFL: Cannot read properties of null
```
**Cause:** A copybook referenced by a COPY statement cannot be found.
**Fix:**
1. Verify `GITNEXUS_COBOL_DIRS` includes the directory containing copybooks (typically `c`)
2. Check that copybook filenames match the COPY target (case-insensitive, after stripping extensions)
3. Ensure copybook files are not in `.gitignore`
### Worker sub-batch timeout
```
Worker 3 sub-batch timed out after 120s (chunk: 200 items)
```
**Cause:** A sub-batch took longer than the timeout. Typically happens when one file is extremely large (50,000+ lines after COPY expansion).
For very large repos (>500MB source), consider `--max-old-space-size=32768`.
### Concurrent analyze corruption
**Rule:** Only ONE `gitnexus analyze` process should run at a time per repository. Concurrent writes to KuzuDB corrupt the database.
If corruption occurs:
```bash
# Remove the KuzuDB directory and re-index
rm -rf .gitnexus/kuzu
gitnexus analyze --force
```
### Slow KuzuDB write phase
The KuzuDB write phase (132s for PROJECT-NAME) is the bottleneck for large COBOL repos. This is proportional to the number of nodes and edges being written. Reducing `MAX_DATA_ITEMS_PER_FILE` or excluding non-essential directories from `GITNEXUS_COBOL_DIRS` can help.
### Verbose output
Enable verbose logging to see per-phase timing and statistics:
The `extractCobolSymbolsWithRegex()` function in `cobol-preprocessor.ts` performs single-pass, state-machine-driven extraction of all COBOL symbols. This document describes the state machine, line processing flow, and every regex pattern used.
## State Machine: Division Tracking
The extractor tracks which COBOL division is currently being processed. Division transitions are detected by the `RE_DIVISION` pattern.
Within the ENVIRONMENT DIVISION, the `currentEnvSection` tracks whether we are in `INPUT-OUTPUT` or `CONFIGURATION` section. SELECT statement accumulation only occurs in `INPUT-OUTPUT`.
## Line Processing Flow
Each raw source line goes through this pipeline:
```
Raw line
|
v
Length < 7? ---------> Skip (flush pending if any)
|
v
Indicator col 7
|
+-- '*' or '/' -----> Comment: skip entirely
|
+-- '-' ------------> Continuation: append to pending line
|
+-- other ----------> Normal: flush pending, strip inline comments (|),
buffer as new pending logical line
```
After all lines are processed, the final pending line is flushed, along with any accumulated SELECT statement, SORT/MERGE accumulator, and any open EXEC block (truncated file without `END-EXEC`).
### Inline Comment Stripping
Enterprise COBOL (particularly Italian dialect) uses the pipe character `|` as an inline comment marker. The `stripInlineComment()` helper is **quote-aware**: it tracks whether the scan position is inside a single- or double-quoted string and only treats `|` as a comment marker when outside quotes. Pipe characters inside string literals are preserved.
Free-format `*>` inline comment stripping uses the same quote-aware approach: the scanner walks character by character, toggling quote state, and only recognizes `*>` as a comment marker when not inside a quoted string.
### Patch Marker Handling
The `preprocessCobolSource()` function (run before extraction in the worker) replaces non-standard content in columns 1-6. Standard COBOL expects spaces or digit sequence numbers in this area. If any letter or `#` character is found, the entire sequence area is replaced with 6 spaces:
```
Before: mzADD MOVE WK-AMT TO WK-TOTAL
After: MOVE WK-AMT TO WK-TOTAL
```
This preserves exact line count for position mapping.
## Regex Pattern Reference
All patterns are compiled once as module-level constants and reused across calls.
SELECT statements are accumulated across multiple lines until a period terminator is found, then parsed for ASSIGN, ORGANIZATION, ACCESS, RECORD KEY, and FILE STATUS clauses.
| `RE_PROC_USING` | `\bPROCEDURE\s+DIVISION\s+USING\s+([\s\S]*?)(?:\.\|$)` | USING parameters | `PROCEDURE DIVISION USING WK-PARAM` |
| `RE_ENTRY` | `\bENTRY\s+"([^"]+)"(?:\s+USING\s+([\s\S]*?))?(?:\.\|$)` | ENTRY point | `ENTRY "SUBPROG" USING WK-DATA` |
| `RE_MOVE` | `\bMOVE\s+((?:CORRESPONDING\|CORR)\s+)?([A-Z][A-Z0-9-]+)\s+TO\s+(.+)` | MOVE statement (supports CORR abbreviation and multi-target) | `MOVE WK-NAME TO OUT-NAME`, `MOVE CORR WK-IN TO WK-OUT` |
The USING parameter list (`RE_PROC_USING`) is split on `\bRETURNING\b` before tokenization -- any RETURNING clause and everything after it is excluded from the parameter list (`.split(/\bRETURNING\b/i)[0]`).
Note: `RE_PROC_SECTION` and `RE_PROC_PARAGRAPH` require exactly 7 spaces of leading indentation (COBOL area A starting at column 8). This is the standard COBOL paragraph indentation.
### All-Division Patterns
These patterns are checked regardless of current division:
| `SORT_CLAUSE_NOISE` | Set of SORT/MERGE clause keywords filtered from USING/GIVING file lists: `ON`, `ASCENDING`, `DESCENDING`, `KEY`, `WITH`, `DUPLICATES`, `IN`, `ORDER`, `COLLATING`, `SEQUENCE`, `IS`, `THROUGH`, `THRU`, `INPUT`, `OUTPUT`, `PROCEDURE` |
SORT and MERGE statements are accumulated across multiple lines (like SELECT) until a period terminator is found, then parsed for USING/GIVING file lists and INPUT/OUTPUT PROCEDURE targets. The `flushSort()` helper encapsulates the flush-and-parse logic, mirroring the existing `flushSelect()` pattern. Both helpers are called at EOF to handle truncated files.
### GO TO Multi-Target
`RE_GOTO` captures all paragraph names in a `GO TO` statement, including the multi-target form `GO TO p1 p2 p3 DEPENDING ON x`. The captured group contains all target names (space-separated), which are split into individual targets. Each target produces a separate `gotos` entry.
### PROGRAM-ID Detection
PROGRAM-ID is detected regardless of the current division state. This handles sibling programs that appear after `END PROGRAM` and omit the `IDENTIFICATION DIVISION` header -- the extractor will still capture the PROGRAM-ID and push a new program boundary.
| `RE_END_EXEC` | `\bEND-EXEC\b` | End of EXEC block | `END-EXEC` |
EXEC blocks accumulate all lines between `EXEC SQL/CICS` and `END-EXEC`, then delegate to `parseExecSqlBlock()` or `parseExecCicsBlock()` for detailed extraction.
## Excluded Paragraph Names
The following names are excluded from paragraph detection to avoid false positives from division/section headers:
```
DECLARATIVES, END, PROCEDURE, IDENTIFICATION,
ENVIRONMENT, DATA, WORKING-STORAGE, LINKAGE,
FILE, LOCAL-STORAGE, COMMUNICATION, REPORT,
SCREEN, INPUT-OUTPUT, CONFIGURATION
```
Additionally, paragraph candidates containing `DIVISION` or `SECTION` as substrings are excluded.
## MOVE Skip List (Figurative Constants)
MOVE statements where the source is a figurative constant are skipped:
```
SPACES, ZEROS, ZEROES, LOW-VALUES, LOW-VALUE,
HIGH-VALUES, HIGH-VALUE, QUOTES, QUOTE, ALL
```

GitNexus indexes each repo independently, then a _group_ stitches the per-repo indexes into a single cross-repo view that the `impact`, `query`, and `context` tools can traverse. If your services live in one monorepo, much of this still applies — set each service as a member of a group and use the `service` prefix to scope queries — but the walkthrough assumes the harder multi-repo case.
## Mental model
- Each repository has its own `.gitnexus/` index (a LadybugDB graph of symbols, relationships, processes). `gitnexus analyze` in each repo produces that index completely independently.
- A **group** is a higher-level construct stored at `~/.gitnexus/groups/<group>/` that references the per-repo indexes by their registry name.
- Sync-time extractors walk each member repo and emit **contracts** — provider or consumer records keyed by a canonical `contractId` (`grpc::auth.AuthService/Login`, `http::GET::/orders`, etc.).
- The sync step matches providers and consumers that share a `contractId` and writes **cross-links** to `<groupDir>/contracts.json`. Those cross-links are what lets `impact({repo: "@<group>", target: "X"})` hop from one repo into another.
- Contracts come from three places: automatic contract extractors (`grpc-extractor`, `http-route-extractor`, `topic-extractor`), a manifest escape hatch (`config.links` in `group.yaml`), and — for same-name symbol matches where no contract is declared — the exact-match matching cascade in [`matching.ts`](../../gitnexus/src/core/group/matching.ts).
- Each repo stays editable and re-indexable on its own. Re-run `gitnexus analyze` in a repo when it changes, then `gitnexus group sync <group>` to refresh `contracts.json`. `gitnexus group status` reports which members are stale.
## Prerequisites
- GitNexus installed and runnable as `gitnexus` or `npx gitnexus` (see the root [README.md](../../README.md)).
- Each service repository checked out locally. No requirement that they share a parent directory — the group references them by registry name.
- Write access to `~/.gitnexus/` (the default gitnexus home; see `getDefaultGitnexusDir` in [`storage.ts`](../../gitnexus/src/core/group/storage.ts)).
## Step-by-step walkthrough
The example uses three services — a TypeScript API gateway, a Go orders service, and a Python inventory service — with gRPC between them. The gateway is an `orders` consumer; the orders service is both an `orders` provider and an `inventory` consumer; the inventory service is an `inventory` provider.
### 1. Index each repository
Run `analyze` from inside each service repo (or pass the path). The CLI surface lives in [`gitnexus/src/cli/analyze.ts`](../../gitnexus/src/cli/analyze.ts) and is wired in [`gitnexus/src/cli/index.ts`](../../gitnexus/src/cli/index.ts).
```bash
cd ~/code/gateway && npx gitnexus analyze
cd ~/code/orders && npx gitnexus analyze
cd ~/code/inventory && npx gitnexus analyze
```
Useful flags:
-`--force` — reindex even if up to date.
-`--embeddings` — generate embedding vectors (needed only if you want semantic search; the exact-match cross-repo cascade does **not** need them).
-`--name <alias>` — register the repo under a specific alias when two repos share a basename (e.g. two `api/` folders).
-`--skip-git` — index a checkout that isn't a git repo.
Each run writes a `.gitnexus/` folder in the repo and registers the repo in `~/.gitnexus/registry.json`. Confirm with `npx gitnexus list`.
### 2. Author `group.yaml`
Create the group directory and edit the config. Either use the CLI scaffolder or write the file directly — both produce the same shape consumed by [`config-parser.ts`](../../gitnexus/src/core/group/config-parser.ts).
Field notes (schema in [`types.ts`](../../gitnexus/src/core/group/types.ts)):
-`version` — must be `1`. The parser rejects anything else.
-`name` — required; used for the group directory name and all CLI / MCP calls.
-`repos` — a mapping from **group path** (a logical name you choose; can be a hierarchy like `backend/orders`) to **registry name** (the name shown by `npx gitnexus list`). Both sides appear throughout the tooling: contract rows use the group path; `@<group>/<groupPath>` routes tools to a single member.
-`links` — optional manifest escape hatch, one entry per explicit cross-repo contract. Validated by the parser: `from` and `to` must be known repo paths, `type` must be one of `http | grpc | topic | lib | custom`, and `role` must be `provider | consumer`.
-`detect` — toggles per extractor family. Defaults (set in `config-parser.ts`) turn `http`, `grpc`, `topics`, and `shared_libs` on; disable the ones you don't use to speed up sync.
-`matching` — thresholds for the matching cascade. The exact match is always run; other strategies depend on indexer state. Two optional fields reduce false-positive cross-links in large groups:
-`exclude_links_paths` — list of HTTP paths to exclude from cross-link matching (default `[]`). Contracts at these paths are still extracted and visible in the registry, but they don't produce cross-repo links. Useful for health-check endpoints (`/ping`, `/health`) that every service exposes. Trailing slashes are normalized.
-`exclude_links_param_only_paths` — when `true`, exclude routes where every segment is `{param}` (e.g. `/{param}`, `/{param}/{param}`) from cross-link matching (default `false`). Mixed routes like `/users/{param}` are not affected.
### 3. Sync the group
```bash
npx gitnexus group sync payments-platform --verbose
```
What this does (see [`sync.ts`](../../gitnexus/src/core/group/sync.ts)):
1. Opens each member's per-repo LadybugDB.
2. Runs the HTTP, gRPC, and topic extractors against the source files.
3. Applies manifest `links` through [`manifest-extractor.ts`](../../gitnexus/src/core/group/extractors/manifest-extractor.ts).
4. Runs the exact-match cascade, joining providers and consumers that share a normalized `contractId`.
5. Writes `contracts.json` in the group directory.
Flags:
-`--exact-only` — stop after the exact cascade; skip BM25 and embedding fallback.
-`--skip-embeddings` — run exact plus BM25 but not embedding-based matching.
-`--allow-stale` — don't warn if a member's index is stale.
-`--json` — machine-readable output.
The same operation is available over MCP as `group_sync({ name: "payments-platform" })` — see [`tools.ts`](../../gitnexus/src/mcp/tools.ts).
### 4. Inspect the registry
Use `gitnexus group contracts` for the CLI view or read the `gitnexus://group/<name>/contracts` MCP resource for the same data.
```bash
npx gitnexus group contracts payments-platform --type grpc --json
Staleness of the underlying indexes shows up in `npx gitnexus group status payments-platform` or the `gitnexus://group/<name>/status` resource.
### 5. Run cross-repo impact with `@<group>` routing
From any shell (you do **not** have to `cd` into a member repo), the normal `impact` / `query` / `context` tools accept `repo: "@<group>"` to fan out across all members, or `repo: "@<group>/<memberPath>"` to target one member. Routing is implemented in [`resolve-at-member.ts`](../../gitnexus/src/core/group/resolve-at-member.ts) and described in [`tools.ts`](../../gitnexus/src/mcp/tools.ts).
Phase 1 walks within the anchor member; Phase 2 hops across the Contract Bridge wherever a cross-link endpoint matches an impacted symbol. See [`cross-impact.ts`](../../gitnexus/src/core/group/cross-impact.ts) for the bridge query.
## How gRPC extraction works
`GrpcExtractor` ([`grpc-extractor.ts`](../../gitnexus/src/core/group/extractors/grpc-extractor.ts)) runs two passes per member repo:
1.**Proto map.** Every `**/*.proto` file is parsed to enumerate `service Foo { rpc Bar(...) }` blocks and (transitively) resolve the package name. Each RPC method becomes a provider contract with `contractId = grpc::<package>.<Service>/<Method>` and `confidence = 0.85`. Parsing uses the vendored `tree-sitter-proto` grammar when available and falls back to a length-preserving manual parser (`extractServiceBlocks`) otherwise, so `.proto` extraction works on platforms where the grammar fails to build.
2.**Source scan.** Every source file whose extension matches [`GRPC_SCAN_GLOB`](../../gitnexus/src/core/group/extractors/grpc-patterns/index.ts) is parsed by its language plugin:
| Language | Provider signal | Consumer signal |
|----------|-----------------|-----------------|
| Go ([`go.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/go.ts)) | `pb.RegisterXxxServer(...)`, `pb.UnimplementedXxxServer` embedded in struct | `pb.NewXxxClient(conn)` |
| Java ([`java.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/java.ts)) | `extends XxxServiceGrpc.XxxServiceImplBase` (with or without `@GrpcService`) | `XxxServiceGrpc.newBlockingStub(...)`, `newStub(...)` |
| Node / TS ([`node.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/node.ts)) | NestJS `@GrpcMethod('Service','Method')` | `@GrpcClient` field typed `XxxServiceClient`, `client.getService<X>('Service')`, `new XxxServiceClient(...)`, `new foo.bar.XxxService(...)` in files that call `loadPackageDefinition` |
For each source-scan detection the extractor looks up the short service name in the proto map and picks:
-`grpc::<package>.<Service>/<Method>` when a method is named and the service resolves against the proto map,
-`grpc::<package>.<Service>/*` (wildcard) when only the service is known, or
-`grpc::<ServiceName>/*` when no `.proto` is available at all.
Provider detections land at confidence 0.8 (with proto) or 0.65 (without); consumers at 0.75 or 0.55. NestJS `@GrpcMethod` is fixed at 0.8 because the decorator is self-describing.
### Matching
`matching.ts` lowercases the package/service segment before comparing contract ids, so bindings that capitalize names differently (`auth.AuthService` vs `auth.authservice`) still match. Method names are compared case-sensitively because gRPC's wire path is case-sensitive. Service-only wildcards (`grpc::pkg.Svc/*`) match any method on the same service during cross-linking.
### Known limitations
- **Ambiguous proto resolution.** If a short service name exists in more than one `.proto` file and the source-scan hit can't be narrowed down by shared directory segments (`resolveProtoConflict` refuses to guess), the extractor skips contract emission and logs a warning.
- **Proto packages must be resolvable locally.** Transitive imports that point outside the repo produce an empty package segment, which means the contract id collapses to `grpc::<Service>/<Method>`. Cross-repo matches still work as long as both sides agree on the empty package.
- **Rewrite rules are not implemented.** If the provider repo writes `grpc::orders.OrderService/PlaceOrder` and the consumer repo writes `grpc::orderspb.OrderService/PlaceOrder`, they won't cross-link automatically. Use `config.links` to declare the correspondence (see below).
- **One sync = one snapshot.** Contracts are extracted against the indexed snapshot of each repo. Re-index first, then re-sync; the `status` command and resource surface staleness.
## When automatic extraction isn't enough
The escape hatch is the `links` list in `group.yaml`, handled by [`ManifestExtractor`](../../gitnexus/src/core/group/extractors/manifest-extractor.ts). Each entry is a **one-directional** provider/consumer declaration:
```yaml
version:1
name:payments-platform
repos:
gateway:gateway
orders:orders
inventory:inventory
links:
# Explicit gRPC method: use when naming mismatches stop the
# automatic matcher from cross-linking.
- from:gateway
to:orders
type:grpc
contract:OrderService/PlaceOrder
role:consumer
# Service-level link when you don't want to enumerate methods.
- from:orders
to:inventory
type:grpc
contract:InventoryService
role:consumer
# Works for HTTP too — use `METHOD::/path` form for the exact
# handler, or just `/path` for a method-agnostic wildcard.
- from:gateway
to:orders
type:http
contract:POST::/orders
role:consumer
```
What the manifest extractor does (see [`manifest-extractor.ts`](../../gitnexus/src/core/group/extractors/manifest-extractor.ts)):
1. Builds a canonical `contractId` with `buildContractId` — the same canonicalization used by the automatic extractors, so manifest links cross-match automatic contracts on the other side.
2. Tries to resolve each side to a real graph symbol (the `Route` node for HTTP, a `Function|Method` / `Class|Interface` for gRPC, a `Package|Module` for `lib`).
3. If resolution fails, falls back to a deterministic synthetic uid (`manifest::<repo>::<contractId>`) so both sides still line up in cross-impact — name-only links still work when the symbol isn't in the graph.
4. Emits both a provider and a consumer `StoredContract` (confidence `1.0`, `source: "manifest"`) and a `CrossLink` with `matchType: "manifest"`.
Use `links` for exactly the cases the extractor can't infer: different package names across repos (see #701), hand-rolled transports, cases where the provider repo isn't checked out locally but you still want a record, or any contract whose provider and consumer simply don't share a surface the extractors know how to pattern-match.
History: the manifest extractor used to be silently skipped by the sync pipeline; that was fixed in [#827](https://github.com/abhigyanpatwari/GitNexus/pull/827) (tracking issue #826). If you ever see `config.links` with zero cross-links in `contracts.json`, make sure you're on a build that includes that fix, then re-run `group sync`.
## Troubleshooting
1.**`contracts.json` is empty after a sync.** Either no member repo contained a recognizable gRPC pattern, or the extractors are disabled in `detect`. Confirm `detect.grpc: true` and re-run with `--verbose`.
2.**A known provider/consumer pair doesn't cross-link.** Most common cause: the package segment differs. Check the raw contract ids with `gitnexus group contracts <name> --unmatched` — if you see two same-method contracts with different package prefixes, add a manifest `links:` entry to bridge them (no automatic rewrite rules yet).
3.**`matchType: "manifest"` is missing entirely.** The extractor needs `config.links` to be non-empty and the sync pipeline to actually call it — verify you're on a post-#827 build. Empty contract rows for manifest links usually mean `resolveSymbol` couldn't find a graph match; the synthetic uid still lets cross-impact work, it just won't carry a file path.
4.**Ambiguous proto warnings.** Look for `[grpc-extractor] Ambiguous proto resolution` in the sync logs; that means a service name exists in multiple `.proto` files under the same repo and the path-distance heuristic couldn't pick a winner. Resolve by renaming the service or declaring the intended pairing in `config.links`.
5.**Cross-impact says "stale".** Both sides need a fresh per-repo index _and_ a fresh group sync. Order matters: `gitnexus analyze` in each changed repo, then `gitnexus group sync <name>`. Use `gitnexus group status <name>` to see which side is behind.

# Using GitNexus across Apache Thrift microservices
## When to use this guide
Use this guide when several repositories communicate through Apache Thrift and you want GitNexus to trace impact across provider and consumer boundaries. The walkthrough assumes each service is indexed on its own, then joined through a GitNexus group.
This is not a framework integration guide. GitNexus reads portable Thrift IDL and common Java generated-code shapes. Framework-specific wiring, service discovery, deployment metadata, and private annotations belong outside the open-source core.
## Mental model
-`.thrift` files define the canonical service contract. A method in an IDL service becomes a stable contract id in the form `thrift::<namespace>.<Service>/<Method>`.
- Service wildcard ids in the form `thrift::<namespace>.<Service>/*` are supported as manifest and matching fallback forms when a service-level link is needed.
- Java generated-code usage points GitNexus toward implementation and call sites. Providers commonly implement generated `Service.Iface`; consumers commonly hold or construct generated service interfaces or clients.
- Group sync matches provider and consumer contracts with the same id, then cross-repo impact can hop through those links.
- Framework-specific wiring should be modeled by extractor plugins, manifest links, or downstream integrations rather than hard-coded into core Thrift support.
-`thrift::billing.v1.OrderService/*` as a service-level manifest or matching fallback form
## Java provider example
Generated Java code usually exposes an `Iface` interface for the service. A provider implementation can be detected when it implements that generated interface.
With the IDL available, GitNexus can connect the implementation to `thrift::billing.v1.OrderService/PlaceOrder` and `thrift::billing.v1.OrderService/GetOrder`.
## Java consumer examples
Consumers are strongest when Java usage can be tied back to the IDL namespace and service.
When IDL context is missing, GitNexus may still emit a weaker consumer signal for generated `Iface` or `Client` shapes, but confidence is lower.
## Group configuration
New group configs enable Thrift contract detection by default. Keep `detect.thrift: true`
when a group should scan for Thrift contracts, or set it to `false` to skip Thrift
extraction for that group.
```yaml
version:1
name:billing-platform
description:Fictional services connected by Apache Thrift
repos:
checkout:checkout-service
billing:billing-service
links:[]
detect:
http:true
grpc:false
thrift:true
topics:false
shared_libs:true
```
To disable Thrift extraction explicitly:
```yaml
detect:
thrift:false
```
After indexing each member repository, run group sync to extract contracts and write cross-repo links:
```bash
npx gitnexus group sync billing-platform
```
## Manifest escape hatch
Use manifest links when automatic extraction cannot see a provider or consumer, or when generated code is wrapped behind an abstraction. Write the contract without the `thrift::` prefix; GitNexus canonicalizes it to the full Thrift contract id.
```yaml
links:
- from:checkout
to:billing
type:thrift
contract:billing.v1.OrderService/PlaceOrder
role:consumer
```
GitNexus canonicalizes that manifest entry to `thrift::billing.v1.OrderService/PlaceOrder` and uses it to connect the two repositories.
## Known limitations
- Java detection currently targets v1 generated-code patterns.
- Maven and POM dependency coordinates are not used for inference.
- Framework-specific annotations and service discovery metadata are ignored by open-source Thrift extraction.
- Ambiguous same-name services are skipped instead of guessed.
- Java consumers without IDL context are lower confidence and limited to generated `Iface` and `Client` shapes.
- CALL USING supports mixed modes: `USING BY REFERENCE WS-A BY CONTENT WS-B BY VALUE WS-C`
- CALL USING `ADDRESS OF` and `OMITTED` must be filtered from parameter lists
- EXEC DLI can have multiple SEGMENT levels in hierarchical retrieval (use matchAll)
- DECLARATIVES can have multiple USE sections (one per file + catch-all for INPUT/OUTPUT/I-O/EXTEND)
- INSPECT TALLYING can have multiple counters in a single statement
- STRING/UNSTRING can span multiple lines (need accumulator pattern)

# Complete COBOL Language Feature Coverage
## Overview
Implement the remaining 25 unhandled COBOL language features and fix 10 partial features to achieve ~95% coverage (up from 71.9%). The goal is to build the richest possible knowledge graph from COBOL codebases, enabling a future `modernize` MCP command (out of scope for this plan) that would use the graph to assist with COBOL-to-modern-language migration.
## Problem Statement
The COBOL processor currently handles 54 of 89 applicable language features (71.9%). The 25 unhandled features represent real data loss in the knowledge graph:
- **Cross-program data flow** is invisible (CALL ... USING parameters not extracted)
- **IMS/DB programs** produce empty graphs (EXEC DLI not recognized)
- **String transformation logic** is invisible (STRING/UNSTRING/INSPECT not tracked)
- **SQL copybook dependencies** are missing (EXEC SQL INCLUDE not mapped)
- **Error handling flows** are lost (DECLARATIVES/USE AFTER not captured)
## Proposed Solution
Implement features in 4 phases, ordered by graph value density (edges created per LOC of implementation). Each phase is independently shippable and testable.
## Technical Approach
### Phase 1: High-Value Data Flow Edges (~150 LOC, ~8 new edge types)
The highest-ROI features: they create new ACCESSES and IMPORTS edges that directly improve impact analysis.
**Critical research finding**: Multi-line statement accumulation is the dominant challenge. CALL USING, STRING/UNSTRING, and multi-line data item clauses all span multiple lines in production COBOL. The free-format path processes each line independently — these features need statement accumulators (like SORT/SELECT) or the free-format path needs multi-line awareness. Estimated LOC increased from 110 to 150 to account for accumulator infrastructure.
- **What:** After capturing CALL target, scan for USING clause. Extract parameter names (reuse USING_KEYWORDS filter). Store as `calls[].parameters: string[]`
- **Interface:** Add `parameters?: string[]` to calls array type in CobolRegexResults
- Mixed modes: `CALL 'PGM' USING BY REFERENCE WS-A BY CONTENT WS-B BY VALUE WS-C`
- Pointer passing: `CALL 'PGM' USING ADDRESS OF WS-A`
- Placeholder: `CALL 'PGM' USING OMITTED WS-B`
- Filter keywords: add `ADDRESS`, `OMITTED`, `LENGTH` to USING_KEYWORDS (already has BY/VALUE/REFERENCE/CONTENT)
- **Impact tool enhancement:** CALL-USING edges enable BFS traversal through parameter data flow — single most impactful edge type for COBOL impact analysis
#### 1.3 STRING/UNSTRING data flow -> ACCESSES edges
- **File:** `cobol-preprocessor.ts` (new section in extractProcedure)
- **What:** Accumulate multi-line STRING/UNSTRING until period or END-STRING/END-UNSTRING. Extract sources and INTO targets.
- IBM allows `OCCURS 0 TO n DEPENDING ON` (zero minimum) and `OCCURS UNBOUNDED DEPENDING ON` (V6.4)
- Subscripted controlling fields: `DEPENDING ON WS-COUNT(WS-IDX)` — strip subscripts before storing
- **Pre-existing gap**: Multi-line data item clauses without continuation indicator are NOT captured. `05 WS-TABLE\n OCCURS 100\n DEPENDING ON WS-COUNT.` — the current RE_DATA_ITEM only gets the first line, `rest` is empty. Fixing properly requires a data item accumulator (like SELECT). **Defer full fix to Phase 3; implement same-line capture now.**
- KEY IS fields: `ASCENDING KEY IS WS-KEY-1 WS-KEY-2` — capture for SEARCH ALL resolution
- INDEXED BY: `INDEXED BY IDX-1 IDX-2` — capture for SET/SEARCH context
- Numeric with sign/decimal: `VALUE -123.45`, `VALUE +1`
-`VALUE IS` optional — both `VALUE 'A'` and `VALUE IS 'A'` valid
- **Decimal vs period ambiguity**: `VALUE 100.` — is `.` decimal or terminator? `parseDataItemClauses` already strips trailing period, so this is handled
- IBM V6.4: floating-point `VALUE 1.0E5` — extend numeric regex if needed
- Implementation: use a pragmatic `extractValue(rest)` function, not a single complex regex
- **Graph:** CodeElement node + ACCESSES edge to `<ims>:<segmentName>` Record node with reason `dli-{verb}`; ACCESSES edges to INTO/FROM data areas; PSB ACCESSES for SCHD
- **Tests:** `EXEC DLI GU USING PCB(1) SEGMENT(CUSTOMER) INTO(WS-CUST) END-EXEC`
**Research insights (dual IMS interface):**
- **EXEC DLI**: Embedded command interface for CICS-DL/I programs only
- **CBLTDLI CALL**: Batch interface via `CALL 'CBLTDLI' USING function-code PCB io-area SSA1..SSA15`
- CBLTDLI is already captured as a CALL to 'CBLTDLI' — enrich with USING parameter semantics later
- Multiple SEGMENT levels in hierarchical retrieval — use `matchAll` on segment regex
- **Graph:** ACCESSES read on inspected field always; write if REPLACING/CONVERTING. Write edges for tally counters. Reason: `cobol-inspect-read`/`cobol-inspect-write`/`cobol-inspect-tally`
- **Tests:** `INSPECT WS-FIELD TALLYING WS-COUNT FOR ALL 'A'` -> read on WS-FIELD, write on WS-COUNT
**Research insights (INSPECT forms by frequency):**
- REPLACING (~60%): `INSPECT WS-STR REPLACING ALL 'A' BY 'B'`
- TALLYING (~25%): `INSPECT WS-STR TALLYING WS-CNT FOR ALL 'A'` — multiple counters possible
- CONVERTING (~10%): `INSPECT WS-STR CONVERTING 'abc' TO 'ABC'`
- Combined (~5%): TALLYING + REPLACING in single statement
- **Needs multi-line accumulator** — INSPECT frequently spans 3-5 lines in production
- Extract tally counters with `([A-Z][A-Z0-9-]+)\s+FOR\b` matchAll pattern
- Filter figurative constants (SPACES, ZEROS) using existing MOVE_SKIP set
### Phase 3: Completeness Fixes (~60 LOC)
Fix the 10 partial features and small gaps.
#### 3.1 CALL ... RETURNING extraction
- Extend RE_CALL processing to capture RETURNING target after the USING clause
- Store as `calls[].returning?: string`
- Graph: ACCESSES write edge with reason `cobol-call-returning`
#### 3.2 SELECT OPTIONAL flag preservation
- Store `isOptional: boolean` in FileDeclaration interface
- Include in Record node description
#### 3.3 ALTERNATE RECORD KEY extraction
- Add regex in parseSelectStatement: `/\bALTERNATE\s+RECORD\s+KEY\s+(?:IS\s+)?([A-Z][A-Z0-9-]+)/i`
- [ ] Integration test assertions updated with exact counts per phase
- [ ] Benchmark run after each phase to track graph growth
## Dependencies & Risks
### Dependencies
- None. All changes are additive to existing COBOL processor code.
- No LanguageProvider changes needed.
- No graph schema changes needed (all new constructs map to existing node labels + edge types).
### Risks
- **preprocessor.ts size**: Currently 1326 LOC. Phase 1+2 adds ~200 LOC -> 1526 LOC. May need to extract helpers into a separate `cobol-data-flow.ts` module if it exceeds 1500.
- **REPLACE statement** (Phase 3.7) is the most complex feature — requires tracking text substitution state across logical lines. Consider deferring to a separate PR if it takes >100 LOC.
- **EXEC DLI** (Phase 2.1) is only testable against IMS codebases. Need fixture data or synthetic test cases.
## Graph Value Ranking by MCP Tool Impact
Research agent analyzed all 5 MCP tools (query, context, impact, detect_changes, rename) against planned edge types:
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Fix 4 HIGH-priority issues from PR #626 code review before merge.
**Architecture:** Minimal targeted fixes — each task is independent. TDD: tests first, then implementation. No refactoring beyond what's needed.
**Paths:** All file paths are relative to the monorepo root (`GitNexus/`). Git commands run from the root. The `gitnexus/` prefix is a package subdirectory, not a separate repo.

### Task 1: Path Traversal — Validate Group Name
**Files:**
- Modify: `gitnexus/src/core/group/storage.ts:17-19` (getGroupDir) and `:63-68` (createGroupDir)
- [ ]**Step 1: Write failing tests for validateGroupName**
In `gitnexus/test/unit/group/storage.test.ts`, add `createGroupDir` and `validateGroupName` to the existing import from `'../../../src/core/group/storage.js'` (line 6-11). Then add these describe blocks at the end of the outer `describe('Group storage', ...)`:
- [ ]**Step 2: Run tests to verify `vendor` and `target` tests fail**
Run: `cd gitnexus && npx vitest run test/unit/group/service-boundary-detector.test.ts`
Expected: `test_detect_skips_vendor_directory` and `test_detect_skips_target_directory` FAIL (vendor/target not excluded). Other new tests may pass since dotfile exclusion already exists.
- [ ]**Step 3: Add EXCLUDED_DIRS constant and update both walking functions**
In `gitnexus/src/core/group/service-boundary-detector.ts`:
- CLI smoke: one integration test that hits `getGroupDir` / `createGroupDir` (e.g. `group create` or `group add`) with an invalid name proves wiring for every subcommand that resolves a group through storage
### CLI/API entry points accepting groupName
All paths flow through `getGroupDir` (which validates), so coverage is implicit. For reference:
**`listGroups`:** Reads directory names from disk without validation. Not a write path, so no traversal risk. May surface manually-created directories with non-conforming names — accepted as-is, not in scope.
**Risk:**`serviceRe = /service\s+(\w+)\s*\{([^}]*)}/gs` stops at first `}`. Proto services with `google.api.http` annotations inside RPCs contain nested `{ }` blocks.
1. Use regex only to find `service <Name> {` start positions (regex consumes the opening `{`)
2. Initialise depth to 1 immediately after the opening `{`
3. Scan forward char by char: `{` -> depth++, `}` -> depth--; collect into body
4. Stop when depth reaches 0 (the matching closing `}`)
5. Return name + body pairs
Inner `rpcRe` regex remains unchanged — it operates on the already-extracted body.
**Malformed input:** If EOF is reached before `depth` returns to 0, skip the incomplete service (do not add to results). Lock this in the test.
**Scope limitation (v1):** Brace-depth only — no lexer for string literals or comments containing `{`/`}`. Sufficient for `google.api.http` annotations. Known false positive: braces inside `//` comments or quoted strings within proto options. Accepted for v1; a proper proto lexer is out of scope.
### Tests
- Proto with single service, no nesting (regression)
- Proto with `google.api.http` nested braces inside RPC options
- Proto with multiple services
- Proto with nested `option` blocks inside RPC (e.g. `google.api.http`)
- Malformed proto with unclosed brace (graceful handling)
---
## Fix 3: Directory Exclusions in Service Boundary Detector
**Risk:** Walks entire repo tree, only skipping dotfiles and `node_modules`. Extremely slow on repos with `vendor/`, `target/`, `__pycache__/`, `.venv/`.
### Solution
Create `EXCLUDED_DIRS` as a `Set<string>` (alongside existing `SERVICE_MARKERS`, `SOURCE_EXTENSIONS`), for example:
```text
node_modules, vendor, target, build, dist,
__pycache__, .venv, venv, .tox, .mypy_cache,
.gradle, .mvn, out, bin
```
(Implement as `new Set([...])` — the list above is the membership, not a string literal.)
Apply in both:
-`walkForBoundaries` (line 77-78) — replace current inline `=== 'node_modules'` check with `EXCLUDED_DIRS.has(entry.name)`
-`hasSourceFilesInSubdirs` (line 130) — replace `entry.name !== 'node_modules'` with `!EXCLUDED_DIRS.has(entry.name)`
Note: remove the old `=== 'node_modules'` literal from both locations — it is covered by `EXCLUDED_DIRS`.
Dotfile exclusion (`.` prefix) remains as a separate check since it's a pattern, not a name.
Exclusions apply only to `isDirectory()` entries — file names are never checked against `EXCLUDED_DIRS`.
**Tradeoff:** Rare layouts that keep source under names like `out/` or `bin/` will be skipped; accepted for performance on typical monorepos.
**Case sensitivity:**`Set.has` is case-sensitive (matches current `=== 'node_modules'` behavior). Windows case-insensitive FS not handled — accepted as-is, consistent with existing code.

# GitNexus CLI Commands
All commands work via `npx` — no global install required.
Commands below use `node .gitnexus/run.cjs <command>` — the project-local runner `gitnexus analyze` drops next to the index. It auto-selects an available runner at call time (global `gitnexus`, else `pnpm dlx`, else `npx`), so no package-manager assumption and no global install is required.
> **Not analyzed yet, or `node .gitnexus/run.cjs` reports `Cannot find module`** (the gitignored runner is absent — e.g. a fresh clone or `git clean`)? (Re)generate it with `npx gitnexus analyze` from the project root. On **npm 11.x**, if `npx` crashes during install (`node.target is null`), install once with `npm i -g gitnexus` (then `gitnexus analyze`) or use `pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze`. See [#1939](https://github.com/abhigyanpatwari/GitNexus/issues/1939).

1. Index the project: `npx gitnexus analyze`
1. Index the project: `npx gitnexus analyze` (on npm 11.x, `npx` can crash during install — use `pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze` instead; see [#1939](https://github.com/abhigyanpatwari/GitNexus/issues/1939))
2. Reload the Cursor window so it picks up the new hook config.
3. Ask the agent something that triggers `Read` / `Grep` / `Shell rg`. You should see a `[GitNexus]` block appended to the tool result.
4. Diagnose silent no-ops by setting `GITNEXUS_DEBUG=1` in your shell environment — the hook will write Cursor's raw event payload to stderr so you can verify field names.
