feat(cpp): migrate C++ to scope-based resolution model (#938) (#1520)
* fix(cpp): complete scope-resolution parity

* fix(ci): resolve formatting, lint errors for PR #1520

- prettier: format arity-metadata.ts, captures.ts, index.ts
- eslint: rename unused HEADER_GLOB to _HEADER_GLOB
- eslint: replace unsafe parser.parse() with parseSourceSafe()
- eslint: suppress intentional console.warn/log in sync.ts
- eslint: remove unused _it import alias in cpp.test.ts

* fix(ci): complete formatting, lint, and typecheck fixes

- prettier: format call-processor.ts, imported-return-types.ts,
  include-extractor.test.ts, cpp-captures.test.ts, cpp-imports.test.ts
- eslint: suppress intentional console.warn in manifest-extractor.ts
- typecheck: restore 'thrift' in ContractType union (was accidentally
  removed) and add thrift case to exhaustive switch in manifest-extractor

* fix(ci): revert unintended group module changes that broke tests

Restore types.ts, config-parser.ts, matching.ts, sync.ts, and
manifest-extractor.ts to upstream/main versions. The original commit
accidentally removed fields (thrift, workspace_deps, exclude_links_paths,
exclude_links_param_only_paths) from DetectConfig/MatchingConfig/ContractType
which are still referenced by matching.test.ts, config-parser.test.ts,
sync.test.ts and other integration tests.

This PR's scope is C++ scope-resolution parity only — group module
type definitions and logic should remain unchanged.

* fix(codeql): address security and quality alerts

- arity-metadata.ts, interpret.ts: replace single-pass template strip
  regex (/<[^>]*>/g) with a while-loop to fully handle nested templates
  like Map<List<int>> — resolves 'Incomplete multi-character sanitization'
- cpp.test.ts: remove unused vitest 'it' import since the file defines
  its own 'it' via createResolverParityIt — resolves 'Assignment to constant'
- include-extractor.test.ts: use fs.mkdtempSync() instead of predictable
  os.tmpdir()+Date.now() paths — resolves 'Insecure temporary file'
- interpret.ts: remove redundant 'name !== undefined' check (already
  guaranteed by early return) — resolves 'Comparison between inconvertible types'

* review: address Claude review findings on PR #1520

- Findings 1-3 (BLOCKERS): restore include-extractor.ts and its test to
  the main baseline. Block-comment fallback regression, suffix-resolve
  false-positive suppression, and the four deleted regression tests
  (#3-#6) are now back. These changes were unrelated to C++ scope
  parity and should not have been in this PR.

- Finding 4 (MAJOR, partial): revert COMPOUND_RECEIVER_MAX_DEPTH 6 to
  4. No C++ test exercises depth > 4 (cpp-chain-call uses a 2-hop
  chain), so the bump risked silent regressions on other migrated
  languages without justification. The wildcard-origin propagation in
  imported-return-types.ts is retained — C++ #include and using
  namespace both emit wildcard-origin bindings (cpp/import-decomposer
  .ts:40,90), so wildcard propagation is causal to C++ parity.

- Finding 6: tighten write-access dedup test with exact per-field
  counts (nameWrites = 2, addrWrites = 1) instead of total-count + sub
  string containment, so a regression in one of the two name writes
  can no longer be masked.

- Finding 8: skipped. Box-drawing characters in cpp/query.ts comments
  match the established convention used in csharp/java/php query
  files.

Finding 5 (int/long normalization tie-breaker) left as documented
follow-up — proper fix requires resolver-level tie-breaker logic and
risks regressing other arity-matching tests.

* fix(cpp): stop #include from leaking class methods and namespace members (U1)

The C++ registry-primary resolver was emitting impossible CALLS edges
for ordinary headers: an including file's unqualified save() resolved
to User::save and unqualified foo() resolved to ns::foo. Two leak
paths converged on localDefs:

1. expandCppWildcardNames (file-local-linkage.ts) iterated the
   flattened localDefs and exported every simple tail, including
   class-owned methods and namespace-contained symbols. Replaced with
   a scope-aware filter: build nodeId -> owning Scope from
   Scope.ownedDefs and skip defs whose owning scope is Namespace or
   Class.

2. The shared global free-call fallback's pickUniqueGlobalCallable
   walks the workspace registry by simple name and would still hit
   class methods / namespace members even with wildcard expansion
   fixed. Plugged the gap via the existing isFileLocalDef hook —
   semantically 'logically invisible cross-file' — by tracking per-
   file non-globally-visible nodeIds (populateCppNonGloballyVisible,
   called from populateOwners) and adding an ownerId !== undefined
   fast-path for class-owned defs.

Side fix in shared finalize-algorithm.ts: when wildcard expansion
resolves to a real target but produces zero propagating names, the
edge was dropped, taking the file-level IMPORTS edge with it.
Preserve the original wildcard edge so #include dependencies survive
even when the header exposes no unqualified bindings.

Tests: cpp-include-no-class-leak, cpp-include-no-namespace-leak, and
cpp-anon-ns-same-file-visible fixtures. Negative tests mode-gated to
REGISTRY_PRIMARY_CPP=1 via the expected-failures registry — legacy
DAG has no scope-aware filtering on the global fallback; backporting
is out of scope. All 2104 resolver integration tests pass under
registry-primary mode.

* fix(cpp): suppress receiver-bound CALLS when integer-width overloads collide (U2)

C++ arity-metadata normalizes int, long, short, unsigned, size_t to
'int' so single-candidate flows like 'process(42L)' match a 'long'-
typed parameter via loose matching. But when both 'process(int)' and
'process(long)' coexist as method overloads, they both end up with
parameterTypes=['int'] in the registry, and pickOverload's narrowing
returns 2 candidates with no way to disambiguate. The previous code
picked candidates[0] arbitrarily, emitting a CALLS edge to the wrong
overload roughly half the time.

Fix:
- Add isOverloadAmbiguousAfterNormalization in overload-narrowing.ts
  that detects >1 candidate sharing identical parameterTypes sequences.
- Have pickOverload return a new OVERLOAD_AMBIGUOUS sentinel when this
  fires.
- In the receiver-bound-calls loop, when pickOverload signals ambiguity,
  suppress the edge AND add the site to handledSites so the late-stage
  emitReferencesViaLookup pass does not re-emit the pre-resolved
  reference. Without the handled-mark, the reference index still
  carries a toDef and emits the same wrong edge.

Graph schema has no ambiguous-target edge model, so emitting two
edges (one per candidate) would require a separate schema change.
Zero-edge is the only safe outcome.

Other languages: the ambiguity check is a precondition gate, not a
behavior change for normal narrowing. Languages whose normalizers do
not collapse distinct types into a single token (verified by grep
over *-arity-metadata.ts) will never produce >1 candidate with
identical parameterTypes from genuinely distinct declarations, so
the branch is effectively C++-only in practice.

Test: cpp-overload-int-long fixture asserts exactly .toBe(0) CALLS
edges. Count=1 = arbitrary pick (the bug); count>1 = unsupported
ambiguous-edge model. Mode-gated to REGISTRY_PRIMARY_CPP=1 — legacy
DAG has no OVERLOAD_AMBIGUOUS wiring; backporting is out of scope.

All 2105 resolver integration tests pass under registry-primary; all
139 cpp tests pass under both modes (3 negative tests skipped in
legacy as documented).

* test(cpp): add integration coverage for anonymous-namespace, using-namespace conflict, and std-shim leakage (U3+U4+U5)

Three new end-to-end fixtures exercise the resolver pipeline against
scenarios that previously had only unit-level coverage or no coverage
at all (Claude review Finding 7):

U3 — cpp-anon-ns-cross-file:
  helper.cpp declares 'namespace { void worker(); }' and calls it
  internally. caller.cpp declares a separate 'void worker()' and calls
  it. Asserts (a) the cross-file CALLS edge from caller's run() does
  not target helper.cpp's anonymous-namespace worker, and (b) the
  same-file edge from helper_entry() to its own worker still resolves
  (positive guard against a 'no edges at all' regression making the
  negative check vacuously pass). Includes a state-isolation guard
  that re-runs the same fixture and asserts identical results,
  proving clearFileLocalNames() is called by the pipeline entry.

U4 — cpp-using-namespace-conflict:
  Two headers each declaring 'namespace a { foo() }' and
  'namespace b { foo() }' respectively, plus a caller doing
  'using namespace a; using namespace b; foo()'. Asserts exactly
  zero CALLS edges. One edge = arbitrary pick (the bug); two edges
  would require an ambiguous-target edge model GitNexus does not
  have. Depends on U1 — without scope-aware filtering, both foo()s
  would already be in the importer's wildcard binding set as simple
  'foo', so the test would pass for the wrong reason.

U5 — cpp-using-namespace-std-smoke:
  Fixture-local 'namespace std { void cout_write(); void println(); }'
  shim rather than real <iostream> — captures the wildcard-leak
  shape deterministically without depending on system-header modeling
  stability (out of scope per plan). Asserts (a) the project-local
  call resolves correctly, (b) no leak to shim STL symbols, and (c)
  no CALLS/ACCESSES edges from the caller into std-shim.h at all.

Negative tests for U2/U4 mode-gated to REGISTRY_PRIMARY_CPP=1 via
the expected-failures registry; legacy DAG lacks the OVERLOAD_AMBIGUOUS
suppression and the namespace-aware filtering, so the leaks persist
there. All 2112 resolver integration tests pass under registry-primary;
all 146 cpp tests pass under both modes (4 negative tests skipped in
legacy as documented).

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

* fix(cpp): scope-aware isSuperReceiver classification (U1)

The C++ isSuperReceiver hook used a regex `/^[A-Z]\w*::/` that
misclassified any uppercase-qualified call as a super-receiver call.
Singleton::getInstance(), std::Foo::bar(), and PascalCase namespace
calls all entered the super branch, where the absence of an enclosing
class (or wrong MRO context) dropped the resolution entirely.

Fix:
- New optional ScopeResolver hook isSuperReceiverInContext(text,
  callerScope, scopes). Languages where super classification depends
  on caller context define it; receiver-bound-calls.ts prefers it
  when defined and falls back to the simple isSuperReceiver(text)
  otherwise. Other migrated languages (Python, Java, C#, PHP, Go,
  TypeScript) are unchanged.
- C++ implementation: parse the LHS of '::' from the receiver text,
  resolve via findClassBindingInScope, and return true only when
  the LHS is a class-like def in the caller's enclosing class's MRO.
  Returns false for namespace LHS, unresolved LHS, self-class LHS
  (qualified self-calls aren't super), and any non-'::' form.
- Extended the C++ tree-sitter query to capture the LHS of
  qualified_identifier as @reference.receiver so qualified static
  member calls (Singleton::getInstance()) reach the receiver-bound
  Case 2 (class-name receiver) path. Without the receiver capture,
  qualified calls had no explicit receiver and could not resolve
  through any receiver-bound branch.

Test: cpp-namespace-qualified-not-super fixture. Singleton::getInstance()
from a free function asserts exactly 1 CALLS edge through the
qualified-call path. Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2113 resolver integration tests pass; all 147 cpp tests pass under
both modes.

* fix(cpp): suppress receiver-bound CALLS when default-arg overloads collide (U4)

ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and
'void f(int, int = 0)' are declared on S. The previous resolver
returned the first viable candidate via pickOverload's fallback.

Extended isOverloadAmbiguousAfterNormalization to take an optional
argCount: when provided, the predicate compares only the first
argCount slots of each candidate's parameterTypes. Candidates whose
declared-prefix matches up to argCount are treated as ambiguous
because default arguments make all of them equally viable for the
call.

Without argCount, behavior is unchanged (the original int/long
normalization-collapse contract, full-length equality required).
pickOverload now passes site.arity so default-arg ambiguity fires.

Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has
f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges.
Passes under both REGISTRY_PRIMARY_CPP=1 and =0.

All 2114 resolver integration tests pass; all 148 cpp tests pass
under both modes.

* fix(cpp): two-phase template lookup suppresses dependent-base members (U3)

ISO C++ two-phase name lookup: inside a class template body, unqualified
calls MUST NOT bind to members of a dependent base class. Only this->name
or Base<T>::name forms make the lookup dependent. GCC and Clang both
reject the unqualified form with 'declaration of f must be available'.

Before this fix, GitNexus's global free-call fallback walked the
workspace registry by simple name and bound unqualified calls inside
template bodies to dependent-base members, producing CALLS edges the
compiler would reject.

Implementation:
- New languages/cpp/two-phase-lookup.ts module: per-pipeline state
  recording (className, dependentBaseName) pairs at capture time and
  resolving them to nodeId sets during populateOwners.
- captures.ts detectCppDependentBases walks the AST once finding every
  template_declaration containing a class/struct definition. For each,
  it collects template-parameter names (typename T, class T, non-type
  int N, template-template parameters) and walks each base in the
  base_class_clause checking whether any inner type_identifier matches
  a template parameter. Conservative bias: typename T::U, decltype,
  and template-template-parameter shapes also classified as dependent.
- Extended scope-resolution contract's isCallableVisibleFromCaller
  hook with optional callerScope and scopes fields. C++ implements
  the hook to consult isCppDependentBaseMember: when the candidate
  is a member of a dependent base of the caller's enclosing class,
  the hook returns false and pickUniqueGlobalCallable skips the
  candidate.
- clearFileLocalNames also clears the dependent-base state per
  pipeline run.

Fixtures:
- cpp-two-phase-dependent-base: Derived<T> deriving from Base<T>,
  unqualified f() and i inside Derived's body. Asserts zero CALLS
  edges and zero ACCESSES edges respectively.
- cpp-two-phase-this-qualified, cpp-two-phase-non-dependent-base,
  cpp-two-phase-namespace-free-call-inside-template: positive
  fixtures left as documented gaps (this-> and qualified-name
  resolution inside template bodies are pre-existing resolver
  weaknesses independent of U3). Tracked separately.

Negative test mode-gated to REGISTRY_PRIMARY_CPP=1 via the expected-
failures registry; legacy DAG has no two-phase lookup.

All 2116 resolver integration tests pass under registry-primary; all
150 cpp tests pass under both modes (5 negative tests skipped in legacy
as documented).

* fix(cpp): implement V1 ADL (Koenig lookup) for free-function calls (U2)

Plan 2026-05-13-001 U2. Adds argument-dependent lookup as a new
candidate-generating tier in `emitFreeCallFallback`: when ordinary
unqualified lookup is empty, ADL surfaces candidates from each
value-class-typed argument's enclosing namespace.

V1 boundary (locked by cpp-adl-pointer-arg-boundary fixture):
- only direct enclosing-namespace closure
- only directly-named class-type values (pointer / reference / template-
  spec args excluded; closure rules deferred to V2)
- ADL fires ONLY when ordinary lookup is empty (no union-and-resolve)

Parenthesized name `(f)(s)` suppresses ADL per ISO C++
[basic.lookup.argdep]/3.1. Multi-candidate ambiguity (e.g. `process(int)`
vs `process(long)` after C++ int-width normalization) returns the
ADL_AMBIGUOUS sentinel — caller suppresses entirely, mirroring the
OVERLOAD_AMBIGUOUS contract from plan 2026-05-12-002 U2.

Implementation:
- `cpp/adl.ts` — new module: per-pipeline argInfoBySite + noAdlSites Maps
  populated at capture time, classToNamespaceQualifiedName Map populated
  during populateOwners; `pickCppAdlCandidates` returns
  SymbolDefinition | ADL_AMBIGUOUS | undefined
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveAdlCandidates` hook
- `scope-resolution/passes/free-call-fallback.ts` — invokes ADL hook
  between `findCallableBindingInScope` and `pickUniqueGlobalCallable`;
  marks site handled on `'ambiguous'` so emit-references doesn't retry
- `cpp/captures.ts` — detects `parenthesized_expression` function wrap;
  per-arg classification (pointer/reference/value class) preserving the
  shape info the existing arity-narrowing normalizer strips
- `cpp/scope-resolver.ts` — registers hook, populates associated
  namespaces, clears state in loadResolutionConfig

Negative tests (parens, pointer-boundary, ambiguous) gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG has no V1/V2
ADL boundary or ADL_AMBIGUOUS suppression.

154/154 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
147 pass + 7 skipped under =0 (legacy parity baseline).

* fix(cpp): inline namespace transitive walking + qualified namespace resolution (U5)

Plan 2026-05-13-001 U5. Two ISO C++ inline-namespace semantics:

1. Unqualified-lookup transitive visibility: inline-namespace members
   reach the enclosing namespace's scope as if declared there. The
   `populateCppNonGloballyVisible` exemption keeps them globally visible
   so cross-file unqualified lookup finds them.

2. Qualified-receiver transitive visibility: `outer::foo()` resolves to
   `outer::v1::foo()` when `v1` is inline (and through arbitrarily-deep
   nesting like `outer::v1::experimental::foo`, matching libc++ `__1` /
   libstdc++ `__cxx11`).

The second behavior required a new resolver case in
`receiver-bound-calls.ts` (Case 1.5: language-specific qualified-receiver
member lookup) because C++ qualified-namespace member calls had no prior
resolution path — receiver-bound Case 1 only handled
`ParsedImport.kind === 'namespace'` (Python/JS-style) and Case 2 handles
class receivers, neither of which fired for `outer::foo()`. The new
hook `resolveQualifiedReceiverMember` is opt-in; languages without
C++-style qualified-name semantics omit it.

Implementation:
- `cpp/inline-namespaces.ts` — new module: per-pipeline
  `inlineNamespaceRangesByFile` + `inlineNamespaceScopeIds` Sets;
  `markCppInlineNamespaceRange` at capture time;
  `populateCppInlineNamespaceScopes` resolves ranges → scope IDs;
  `resolveCppQualifiedNamespaceMember` walks namespace scopes by simple
  name and descends transitively through inline children only.
- `scope-resolution/contract/scope-resolver.ts` — adds optional
  `resolveQualifiedReceiverMember` hook to the contract.
- `scope-resolution/passes/receiver-bound-calls.ts` — Case 1.5 invokes
  the hook between Case 1 (namespace imports) and Case 2 (class-name
  receiver). Returns undefined for non-namespace receivers so Case 2
  still resolves class-qualified calls.
- `cpp/captures.ts` — detects `inline` keyword child on
  `namespace_definition`; records 1-based range to match Scope.range.
- `cpp/file-local-linkage.ts` — `populateCppNonGloballyVisible` exempts
  inline-namespace scopes so cross-file unqualified lookup keeps their
  members visible.
- `cpp/scope-resolver.ts` — wires `populateCppInlineNamespaceScopes`
  into populateOwners (BEFORE `populateCppNonGloballyVisible` so the
  exemption sees populated state); registers
  `resolveQualifiedReceiverMember` hook.

4 fixtures: `cpp-inline-namespace-unqualified`, `-versioned`,
`-nested` (two transitive inline hops, STL `__1` shape), and
`-adl-participation` (composes with U2 — ADL surfaces records declared
inside inline child namespaces). All 4 assert exactly 1 CALLS edge with
correct target file.

Versioned fixture gated under LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp
— legacy DAG can't disambiguate two same-name foos without inline
awareness. Other 3 coincidentally resolve in legacy.

158/158 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
150 pass + 8 skipped under =0 (legacy parity baseline).

* test(cpp): Phase 5 cross-unit composition tests for U1/U2/U3/U5

Plan 2026-05-13-001 Phase 5. Locks in correct behavior at the
intersections between the previously-shipped scope-resolver units.

Enhancement to U1: `isSuperReceiverInContext` strips template-argument
lists (`Base<T>` → `Base`) and namespace prefixes (`outer::v1::Base` →
`Base`) before resolving the receiver in the caller's scope chain. This
makes the super-receiver classification work for template-class
heritage shapes like `Base<T>::method()` and `outer::v1::Base<T>::f()`.

Three fixtures + four tests:

- `cpp-phase5-u1-u3-qualified-base-call`:
  `template<class T> struct Derived : Base<T>` with
  `Base<T>::method()` inside a template body. Asserts NO mis-routing
  (count = 0) — documents the V1 gap that template-class inheritance
  isn't captured as EXTENDS by the legacy DAG, so MRO walks are empty
  and the super branch can't dispatch. The composition still works
  correctly: U1's template-arg-stripping classifies `Base<T>` as a
  super candidate, but the empty-MRO terminates without false edges.

- `cpp-phase5-u2-u3-adl-from-derived`:
  `Derived : Base<T>` where `Base::record` shadows `audit::record`.
  Unqualified `record(e)` inside the template body should resolve via
  ADL to `audit::record` (because U3 + the `isFileLocalDef` class-
  owned filter suppress `Base::record`). Asserts 1 edge to audit.h
  and 0 edges to base.h.

- `cpp-phase5-u3-u5-inline-base`:
  `template<class T> struct Derived : outer::v1::Base<T>` where `v1`
  is inline. Unqualified `f()` inside `Derived<T>::g()` should NOT
  bind to Base::f (dependent-base suppression even across inline
  namespace prefix). Asserts count = 0.

Phase 5 tests asserting no-false-positives are gated under
LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.cpp — legacy DAG over-
resolves without the template-arg-stripping qualified-receiver path
and without two-phase dependent-base suppression.

162/162 cpp integration tests pass under REGISTRY_PRIMARY_CPP=1;
152 pass + 10 skipped under =0 (legacy parity baseline).

851d2ab749 fix(typescript): address review findings — formatting + tighter test assertions
Addresses the automated review findings on PR #1175:

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

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

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

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

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

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

7be595d317 fix(typescript): capture missed CALLS edges from HOF callbacks and JSX
Two distinct gaps in the TypeScript scope-resolution path were silently
dropping call edges in real-world React + TanStack + Zustand codebases.
On the bug reporter's repo (Sourcerer-fe, 1185 src/ functions), 504
missing Function->Function CALLS edges are now captured (+61.6%) and
the no-outgoing-CALLS orphan rate drops from 73.2% to 60.3%.

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

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

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

feat(ingestion): TypeScript registry-primary scope resolution (Ring 3) (#1050)
* feat(ingestion): TypeScript registry-primary scope resolution (Ring 3)

- Add TypeScript ScopeResolver stack (query/captures/interpret, import decomposition, hooks, arity, merge, receiver binding) and register in SCOPE_RESOLVERS.

- Harden shared compound receiver and receiver-bound CALLS pass for map for-of tuple bindings, dotted typeRef shapes, and callable-alias fallbacks.

- Flip TypeScript into MIGRATED_LANGUAGES; refresh AGENTS.md and type-resolution-system.md.

- Shared finalize-algorithm updates for cross-file scope parity.

- Tests: TS scope-resolution unit suite; legacy call-processor suite forces REGISTRY_PRIMARY_TYPESCRIPT=0; registry-primary flag test opts out TS in override scenario.

* fix(ingestion): SCC-ordered cross-file return-type propagation + multi-hop re-export resolution

Fix CI failures on PR #1050 (TypeScript registry-primary migration) by
making `propagateImportedReturnTypes` deterministic via reverse-
topological SCC ordering and updating the multi-hop re-export contract
to match `followReexportChain` behavior.

Why: the legacy pass mirrored an intermediate ref instead of the
terminal type when an importer was processed before its source module
had its own typeBindings chain-followed (4-file alias chain regression
in `ts-simple` fixture: `models.User -> service.user -> app.user`
collapsed to `getUser` instead of `User`). Reverse-topological walk of
`indexes.sccs` (leaves first) lets every importer see the source's
already-followed terminal type in a single pass.

Changes:
- `imported-return-types.ts`: rewrite to walk SCCs leaves-first, chain-
  follow the source module's typeBindings BEFORE mirroring, and chain-
  follow the importer's typeBindings AFTER mirroring. Cyclic SCCs
  reach a partial fixpoint (no convergence guarantee, ts-circular only
  asserts no-throw).
- `finalize-algorithm.ts`: docstring update on `FinalizeFile.localDefs`
  to reflect that `followReexportChain` resolves multi-hop re-exports
  through barrels even when intermediates do not surface the name -
  surfacing is now a static optimization, not a correctness requirement.
- `contract/scope-resolver.ts` Invariant I3: explicitly document the
  SCC ordering requirement.
- `pipeline/run.ts`: split PROF timer into `finalize` and `propagate`
  so the pass's cost is observable independently.
- `ARCHITECTURE.md` Performance notes: describe SCC-ordered propagation.
- `imported-return-types.ts`: expand chain-depth comment (2x effective
  depth from pre/post follow), add multi-ref break rationale, add
  `ts-simple` motivating-fixture pointer.

Tests:
- `finalize-algorithm.test.ts`: add 4 cases (3-hop chain, cyclic
  re-export visited-set guard, wildcard re-export fall-through,
  multi-source first-match-wins); fix misleading shared nodeId in the
  thick variant; rename and update the multi-hop test for the new
  contract (transitiveVia assertion on the thin variant).
- `imported-return-types.test.ts` (NEW): unit tests for the SCC pass
  pinning topological collapse, local-annotation guard, missing-source
  skip, and cyclic-SCC no-throw.
- `cross-file-binding.test.ts` + `ts-deep-alias-chain` fixture (NEW):
  5-file integration regression guard for SCC-ordered propagation
  through 4 module boundaries.

Validation: 865 scope-resolution + cross-file tests pass on Windows;
typecheck clean across both packages; only pre-existing Swift overload
failures remain (verified on PR base commit, environmental).

* fix(ingestion): address PR #1050 review findings — side-effect imports, resolve-cache perf, adapter signature

Three independent fixes surfaced by the production-readiness review of
the TypeScript registry-primary scope-resolution migration (RFC #909
Ring 3). All three pass under both REGISTRY_PRIMARY_TYPESCRIPT=0 and =1.

1. Side-effect imports were silently dropped (correctness regression).
   The legacy DAG emitted IMPORTS edges for `import './polyfill'` because
   its tree-sitter query matches `(import_statement source: (string))`
   regardless of clause. The new registry-primary path returned `[]`
   from `splitImportStatement()` for clause-less imports, so no
   ParsedImport / ImportEdge was ever produced — silent file-level edge
   loss. Add a generic 'side-effect' variant to `ParsedImport` and
   `ImportEdge['kind']` in `gitnexus-shared`; finalize resolves the
   target file and pre-finalizes the edge (no `targetDefId`, no
   `BindingRef`) so the SCC fixpoint loop skips it. The TypeScript
   provider now emits + interprets the new kind end-to-end. The
   variant is intentionally generic so other languages (Rust
   `use foo as _`, Python module-init) can adopt it.

2. Per-import re-derivation in `resolveImportTarget` (perf regression).
   The TS adapter built `new Set(allFilePaths)` on every call and let
   `resolveTsImportTarget` re-derive `allFileList` /
   `normalizedFileList` and discard the `resolveCache`. For a workspace
   with N files and M imports that's O(N × M) work per pass. Wrap the
   adapter in a closure that memoizes all five derived values keyed on
   the orchestrator's `ReadonlySet` identity; reset only when the set
   reference changes (start of new pass). New cost: O(N + M).

3. Misleading fake `ParsedImport` in the adapter (architecture).
   The adapter constructed `{ kind: 'named', localName: '_',
   importedName: '_', targetRaw }` to call `resolveTsImportTarget`,
   even though only `targetRaw` and the structural-typed context are
   read. Extract `resolveTsTarget(targetRaw, ctx)` so the adapter has
   an honest signature; `resolveTsImportTarget` still works for other
   callers. Also extract `narrowTsContext` for the type narrowing.

Tests: - New 4-file fixture `typescript-side-effect-imports` with two
    side-effect imports + one named import.
  - New "TypeScript side-effect imports" describe in
    `test/integration/resolvers/typescript.test.ts` (parity-gated by
    `ci-scope-parity.yml` — runs under both flag states).
  - Updated 2 unit tests to expect 1 side-effect ParsedImport and 4
    `@import.statement` matches (was 0 / 3).
  - 785 / 785 TS scope-resolution tests pass under both
    REGISTRY_PRIMARY_TYPESCRIPT=0 and =1.

* fix(scope): address Codex adversarial review findings on PR #1050

Four findings from the Codex adversarial review broke registry-primary
TypeScript resolution for common patterns. All four now have unit and
integration regression coverage that pass under both
`REGISTRY_PRIMARY_TYPESCRIPT=0` (legacy DAG) and the default
registry-primary path.

[high] tsconfig path aliases dropped:
Threaded `tsconfigPaths` through ScopeResolver via a new opaque
`resolutionConfig` parameter and a `loadResolutionConfig(repoPath)`
hook. The orchestrator (`scopeResolutionPhase` + `runScopeResolution`)
loads it once per workspace pass and forwards into every
`resolveImportTarget` call. TypeScript resolver now resolves
`@/services/user` style imports through the standard resolver's alias
branch.

[high] TSX parsed with the wrong grammar:
`emitTsScopeCaptures` now picks the parser/query by `filePath`
(`.tsx` -> TSX grammar) and validates cached trees against the
expected grammar via the new exported `tsCachedTreeMatchesGrammar`
helper. Stale TS-grammar trees for `.tsx` files no longer leak through
the scope query.

[medium] Literal dynamic imports never linked:
Added `kind: 'dynamic-resolved'` to `ParsedImport` and `ImportEdge`.
The decomposer emits a synthetic `@import.literal` capture for
string-literal dynamic imports; the interpreter maps that to
`dynamic-resolved`; finalize pre-finalizes it as a file-level terminal
(same shape as `side-effect`). `import('./feature')` now produces a
real IMPORTS edge under the registry-primary path. Legacy DAG keeps
its existing behavior — the new integration assertion is gated behind
the flag.

[medium] Namespace re-exports invisible from barrels:
The decomposer now emits TWO captures for `export * as ns from './m'`
— the existing `reexport-namespace` import draft AND a synthetic
`@declaration.namespace` capture (via `buildNamespaceDeclarationMatch`).
The latter creates a Namespace `SymbolDefinition` in the barrel's
`localDefs`, so downstream `import { ns } from './barrel'` resolves
through `findExportByName`.

Regression fixtures under `gitnexus/test/fixtures/lang-resolution/`:
- typescript-tsconfig-aliases (`@/` alias)
- typescript-tsx-jsx (Button.tsx + App.tsx with JSX)
- typescript-dynamic-import (`await import('./feature')`)
- typescript-reexport-namespace (`export * as Models from './base'`)

Validation:
- gitnexus-shared builds clean
- gitnexus typecheck clean
- 385/385 TS scope-resolution tests pass under both
  `REGISTRY_PRIMARY_TYPESCRIPT=0` and default

* perf(scope): O(1) defById lookup + bounded re-export depth (PR #1050 round 3)

Addresses the round-3 PR #1050 reviews (Claude adversarial + xkonjin):
both flagged the existing O(N²) `findDefById` linear scan in
`materializeBindings` and the unbounded recursion in
`followReexportChain` as production-readiness blockers for TypeScript
monorepos. Both fixes land alongside their regression tests under
both `REGISTRY_PRIMARY_TYPESCRIPT=0` and the default registry-primary
path.

[high] materializeBindings O(N_files × N_defs × N_edges) → O(N_defs + N_edges):
Build a `nodeId → SymbolDefinition` index map once at the top of
`materializeBindings` (one O(N_defs) pass), then replace the per-edge
`findDefById(files, edge.targetDefId)` linear scan with an O(1)
`defById.get(edge.targetDefId)` lookup. Also drop the now-unused
`findDefById` helper. At realistic TypeScript monorepo scale (~5k
files × ~50 defs/file × ~100k linked import edges) this is the
difference between ~25 s and a few ms inside finalize. Regression
test in `finalize-algorithm.test.ts` builds 200 leaf files +
1 consumer importing one symbol from each, asserts every binding
materializes correctly.

[medium] followReexportChain unbounded recursion:
The existing `visited` set caps depth at `O(N_files)` but allows
recursion proportional to barrel-chain depth, mismatching the
explicit "Iterative DFS to avoid stack overflow" policy in
`tarjanSccs`. Added a `MAX_REEXPORT_DEPTH = 100` constant and a
`depth` parameter to `followReexportChain` (defaults to 0); each
recursive call passes `depth + 1` and the function returns `null`
when the cap is exceeded. 100 is comfortably above any realistic
hand-authored barrel chain (typical depth 1-5; auto-generated
barrels rarely exceed 20) while staying well below JS engine call
stack limits. Regression test wires a 200-link reexport chain and
verifies the crawl terminates cleanly with `linkStatus: 'unresolved'`
(no terminal def reachable within the budget).

[low] synthesizeInstanceofNarrowings bare-identifier-only limitation:
xkonjin's review #4 noted that the LHS narrowing only handles bare
identifiers (`if (x instanceof Foo)`), not member expressions
(`if (user.address instanceof Address)`). Added a JSDoc note
explaining the constraint and pointing readers at field-type
resolution as the workaround for member-chain receivers.

Validation:
- gitnexus-shared builds clean
- gitnexus typecheck clean
- 413/413 tests pass under both flag states for finalize-algorithm +
  TS unit + TS integration suites
- 972/972 tests pass across full scope-resolution + Python +
  C# integration smoke (no cross-language regression)

* refactor(finalize): replace recursive followReexportChain with SCC-condensed iterative closure

The legacy `followReexportChain` walked re-export drafts via mutual
recursion guarded by a per-call visited set + a `MAX_REEXPORT_DEPTH`
ceiling. Recursion is fragile (call-stack ceiling, no bound on depth
that's actually meaningful), so this replaces it with a structurally
better algorithm: a precomputed per-file re-export closure built by
running Tarjan SCC over the re-export sub-graph and propagating names
in reverse-topological order with a bounded intra-SCC fixpoint.

Algorithm (`buildReexportClosures` in finalize-algorithm.ts):

  1. Sub-graph: build the directed graph of `reexport` + `wildcard`
     drafts only (regular/namespace/dynamic imports do not contribute).
  2. SCC condensation: run the same iterative `tarjanSccs` already
     used for the file-level import graph; output is in reverse-topo
     order so out-of-SCC neighbors are always already-finalized.
  3. Per-SCC propagation:
       - Acyclic singleton: one pass populates from neighbors' closures.
       - Cyclic SCC: bounded fixpoint capped at |SCC|+1 iterations.
         With first-wins precedence the closure map is monotone, so
         each name needs at most |SCC| hops to traverse the cycle.

Precedence (preserved from the recursive crawl):
  - Named re-exports take precedence over wildcards.
  - Within each kind, declaration order wins.

Lookup at finalize time becomes O(1) (`lookupReexportedName`), down
from O(chain_depth × drafts) per consult and recursive at that.

Properties vs the legacy implementation:
  - Stack-safe by construction; no `MAX_REEXPORT_DEPTH` guard needed.
  - 1000-hop barrel chains now resolve in full (legacy capped at 100
    and surfaced anything deeper as `unresolved`).
  - Cycles handled structurally via SCC, not via per-call visited set.
  - Same observable semantics: every existing test passes unchanged.

Tests:
  - Replace the obsolete `MAX_REEXPORT_DEPTH (200-hop chain stops
    cleanly without stack overflow)` test (which asserted the OLD
    bug — that deep chains failed to resolve) with a positive
    1000-hop test that asserts full resolution + accurate
    `transitiveVia`. Proves both the recursion is gone AND the
    closure correctly inherits the leaf def across all hops.
  - Update commentary on adjacent re-export tests to reference the
    closure mechanism.
  - Update `FinalizeFile.localDefs` JSDoc + import-decomposer.ts
    inline doc to point at `buildReexportClosures` instead of the
    removed function name.

Validation: - gitnexus-shared builds cleanly.
  - gitnexus typechecks cleanly.
  - 28/28 finalize-algorithm.test.ts tests pass (incl. new 1000-hop).
  - 801/801 TypeScript scope-resolution tests pass under default
    (registry-primary) AND `REGISTRY_PRIMARY_TYPESCRIPT=0` (legacy DAG).
  - 404/404 Python + C# integration tests pass — no regression in
    cross-language consumers of the shared `finalize`.

feat(shared): SCC-aware finalize algorithm with bounded fixpoint (#915, RFC #909 Ring 2 SHARED) (#962)
* feat(shared): SCC-aware finalize algorithm with bounded fixpoint (#915, RFC #909 Ring 2 SHARED)

Implements RFC §3.2 Phase 2 as pure logic in `gitnexus-shared`. Takes
per-file parse output and returns linked `ImportEdge[]` + materialized
module-scope bindings, fully language-agnostic (target resolution,
wildcard expansion, and binding precedence all go through caller hooks).

Three-phase algorithm:

  1. Tarjan SCC over the file-level import graph (iterative, deterministic
     node order, O(V+E)). Returns SCCs in reverse-topological order so
     leaves finalize before dependents — and so disjoint SCCs are
     explicitly surfaced for parallel-processing callers.

  2. Per-SCC bounded fixpoint. For each SCC in topo order, iterate up to
     `N = |intra-SCC edges|`; each pass tries to resolve every still-
     unlinked edge by looking up the imported name in the target file's
     local defs. Stops early when no progress. Edges still unlinked after
     the cap get `linkStatus: 'unresolved'` — keeps malformed inputs
     bounded and preserves the RFC §4v2 capped-signal contract for
     unresolved markers.

  3. Wildcard expansion + module-scope binding materialization. For each
     `wildcard` ParsedImport that linked to a module, expand via
     `expandsWildcardTo` into one `wildcard-expanded` ImportEdge per
     exported name. Bindings per module scope are the merge of local defs
     (`origin: 'local'`), named / alias / reexport imports
     (`origin: 'import' | 'reexport'`), namespace imports (`origin:
     'namespace'`), and wildcard expansions (`origin: 'wildcard'`), with
     precedence delegated to `provider.mergeBindings`.

Dynamic imports rule: `kind: 'dynamic-unresolved'` passes through as an
ImportEdge with `targetFile: null` and no BindingRef.

Re-export flattening: reexport edges land with `transitiveVia: [targetFile]`.
Multi-hop chains settle iteratively across the fixpoint.

Types:
  - Adds `'wildcard'` variant to ParsedImport (parse-time signal for
    `import * from M`). The finalize-only `'wildcard-expanded'` ImportEdge
    kind is unchanged and remains finalize output only, as documented.
  - Exports `finalize` + `FinalizeFile` / `FinalizeInput` / `FinalizeHooks`
    / `FinalizeOutput` / `FinalizedScc` / `FinalizeStats`.

Simple-name derivation: `deriveSimpleName` uses `def.qualifiedName` as the
authoritative source (tail after the last `.`). Defs without a
qualifiedName are not name-resolvable by this algorithm — an explicit
design choice that trades strictness for predictability (no heuristic
nodeId parsing).

Tests (20, all passing):
  - Trivial: empty workspace · acyclic resolution · unresolvable target
    (file + name) · dynamic-unresolved passthrough.
  - Cycles: A↔B two-file cycle linked · cycles packed into SCC with
    isCycle=true · disjoint cycles produce disjoint SCCs · mixed
    linked/unresolved edges reported correctly in stats.
  - Wildcards: one ImportEdge per exported name · unresolved wildcards
    survive as single edges · expanded bindings carry origin='wildcard'.
  - Reexports: transitiveVia carries the intermediate file path.
  - Aliased + namespace: alias preserves targetExportedName under its
    local name · namespace links to module scope even without a module-def.
  - Bindings: locals land as origin='local' · imports layer on via
    mergeBindings · mergeBindings can drop existing (last-write-wins
    precedence honored).
  - SCC-DAG: reverse-topological ordering verified (leaf first).

Combined scope-resolution / model / shadow suite: 229/229 pass.
`tsc --noEmit` clean in both `gitnexus-shared` and `gitnexus`.

Closes part of #909. Unblocks #917 (Registry.lookup's import-chain fast
path consumes finalized ImportEdges); unblocks Ring 3 language migrations
(per-language providers supply FinalizeHooks implementations).

* chore(shared): address #915 review findings — dead code, docs, tests

Review thread on PR #962.

Code changes:
  - Remove dead `resolvedTargets` map + `keyFor` + `ParsedImportKey`
    type alias. The map was populated but never read; originally intended
    to cache / dedup resolutions for later phases but that path was never
    wired (finding 1.1).
  - Drop unused params (`_edgeIndex`, `_hooks`, `_workspace`) from
    `tryFinalize`. No planned fixpoint-state consultation; no reason to
    keep them reserved (finding 2.1).

Documentation:
  - `FinalizeFile.localDefs` now documents the multi-hop re-export
    contract explicitly: `finalize` looks names up in the target's
    static `localDefs`; if B only re-exports from C and doesn't surface
    the name in its own localDefs, A's import of that name from B will
    hit the cap and be marked unresolved. Parsers that want multi-hop
    chains to settle end-to-end must include re-exported names in the
    intermediate file's localDefs (finding 1.2).
  - `FinalizeStats` now documents its counting granularity: all edge
    counters are per-`ParsedImport`, not per-materialized-`ImportEdge`.
    A wildcard expanding to N exports counts as one linked edge;
    dynamic-unresolved pass-throughs count as linked. The bindings map
    is the authoritative "has a BindingRef" source (finding 3.2).

Tests (2 added, 22 total in finalize-algorithm.test.ts, 231/231 combined):
  - Explicit cap-hit → `linkStatus: 'unresolved'` assertion for a cycle
    where the name-level lookup never succeeds (distinct from
    `targetFile: null`; cap exhaustion path) (finding 3.1).
  - Multi-hop re-export contract test: demonstrates both variants —
    intermediate B WITHOUT X in localDefs → unresolved; B WITH X in
    localDefs → resolved to the original source DefId (finding 1.2).

Not addressed (filed as follow-up issues):
  - LanguageProvider.resolveImportTarget vs FinalizeHooks signature
    divergence (finding 1.3) — pre-Ring-3 concern.
  - findDefById O(F×D) scan in Phase 5 (finding 4.1) — acceptable for
    Ring 2; optimize before large-workspace Ring 3 migrations.
