Gergő Magyar	74409a37f6	perf(cpp): index qualified namespace members once per pipeline run (#2788) (#2794) ... * perf(cpp): index qualified namespace members once per pipeline run (#2788) `resolveCppQualifiedNamespaceMember` walked every parsed file — rebuilding a per-file `scopesById` map each time — once per qualified `ns::member()` call site, so the scope-resolution emit phase cost O(callsites x scopes). On a 1,473-file C++ repo that was 25.3 min of a 33-min analyze, with 75% of total self-time in this one function. Its inner `findMemberInNamespaceTransitive` compounded it: each recursion step filtered `scopesById.values()` by parent, O(scopes^2) per file on its own. This is the same bug #1990 fixed in the sibling ADL path (`pickCppAdlCandidates` -> `AdlCandidateIndex`), so it gets the same fix: a `QualifiedNsMemberIndex` (receiver simple name -> member simple name -> callable defs) built lazily once per `parsedFiles` identity and reset by `clearCppInlineNamespaces`, which runs from `cppScopeResolver.loadResolutionConfig` at the start of every pass. Per call site the work drops to two Map lookups. Ordering is preserved exactly — file-major, `parsed.scopes` declaration order, a namespace's own `ownedDefs` before its inline-namespace children, depth-first — because the caller takes `allHits[0]` for the single-hit case and `narrowOverloadCandidates` is first-wins. Non-inline nested namespaces are still not descended into, and same-name hits across inline children still report `'ambiguous'` (#1564). Measured with `PROF_SCOPE_RESOLUTION=1 analyze --force --index-only` on a synthetic corpus (`namespace ns_i { inline namespace v1 { ... } }` plus 20 `ns_j::fn()` call sites per file): | files | emit before | emit after | |-------|-------------|------------| | 100 | 153ms | 16ms | | 200 | 704ms | 24ms | | 400 | 3,293ms | 42ms | | 800 | 16,898ms | 78ms | Before, doubling the file count quadrupled emit; now it doubles. At 800 files total scope resolution goes 17.2s -> 394ms. Output is unchanged, verified rather than assumed: a full graph dump (sorted nodes + relationships) from a baseline build at the parent commit and from this one are byte-identical on all 134 `cpp-*` fixtures merged into a single repo (1573 nodes / 1997 relationships) and on the 400-file synthetic corpus. `test/integration/resolvers/cpp.test.ts` passes 334/334. #1990 shipped its ADL fix without a scaling gate, which is how the bug class came straight back here, so this adds one: `bench/cpp-qualified-ns` measures `(t_large/t_small)/(1600/400)` — 0.93-1.21 indexed versus 3.45 for the old per-call-site scan — alongside a fingerprint over every `receiver::member -> outcome` the corpus resolves, and CI runs it with `--check`. `test/unit/cpp-qualified-ns-index.test.ts` covers the cache invalidation the index introduces. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cpp): address tri-review findings on the qualified-namespace index (#2788) Multi-engine review of this PR (Claude swarm + ce-code-review, Codex gpt-5.6-sol swarm + ce + adversarial) returned two P1s and five smaller findings. All are fixed here. P1 — the index defeated the pipeline's post-language memory release. `scope-resolution/pipeline/phase.ts` evicts each language's files and then calls `forceGc()`, on a stated premise that "This language's ParsedFiles are now unreachable", sizing C/C++ at ~17-20GB on the Linux kernel. The module-level `let qualifiedNsIndexSource` falsified that: it pinned the whole `parsedFiles` array, and the index held defs reaching into those files' scopes, until the *next* C++ pass cleared it — which in a single analyze never comes. C++ is 7th of 16 in SCOPE_RESOLVERS, so the set survived nine later language passes plus emit. Replaced with a `WeakMap<readonly ParsedFile[], QualifiedNsMemberIndex>`, the pattern already used by `moduleScopeIndexByPass` in `cpp/file-local-linkage.ts`. `clearCppInlineNamespaces` still swaps in a fresh WeakMap, because the index has a second input (`inlineNamespaceScopeIds`) the key cannot observe. Measured with `--expose-gc`: 61.2MB retained after the caller drops the array before, 0.1MB after. The ADL twin (`adl.ts`) has the same pattern, so the hazard predates this PR — but `pickCppAdlCandidates` returns early before `ensureAdlIndex` on `noAdlSites`/empty `argInfoBySite`, so it rarely arms, whereas a qualified `ns::member()` index arms on almost every C++ workspace. Moving the ADL twin to a WeakMap is left as a follow-up. P1 — the new bench could not see the regression class it exists to gate. `callSites()` drew every receiver from `ns_${...}`, so the receiver lookup never missed; production is the opposite, since Case 1.5 in `receiver-bound-calls.ts` is reached by every plain-identifier receiver call and misses on most. A rescan reintroduced only on the receiver-bucket-absent path scored 1.279 and PASSED the old bench. The corpus now mirrors production (~1 in 5 receivers name a declared namespace) and adds a namespace reopened across files, a same-name inline nest, a member declared at both namespace and inline-child level, and call sites carrying a real `Callsite` so `narrowOverloadCandidates`/`cppConversionRank`/ `isOverloadAmbiguousAfterNormalization` are inside the fingerprinted surface at all. That same rescan now measures 4.538 and FAILS; defeating the dedup now fails the fingerprint arm where it previously passed byte-identical. The fingerprint moved once, deliberately, for the corpus expansion — recorded in `_rebaseline_2788_review`, explicitly not precedent. Also fixed: - Unbounded recursion aborted analyze. `collectNamespaceMembers` recursed per inline child with no bound and threw an uncontained `RangeError` at inline depth 8000 (`phase.ts`'s try has a `finally`, no `catch`), and a receiver *miss* paid full recursion where the deleted walker skipped on a name mismatch. An explicit work-stack alone would only have converted that into an OOM at depth 6000, because the eager table was quadratic in memory too: for a depth-D chain it legitimately holds D(D+1)/2 entries, since `v2::foo()` is a valid receiver at every level. Replaced with a lazily-queried node graph (per-scope own-member buckets plus direct child links, resolved on demand and memoized per receiver+member). Build is now linear; depth 100000 costs 133ms where 8000 previously threw. - "#1990 shipped without a scaling gate" was false. #1990 did ship `test/integration/cpp-adl-benchmark.test.ts` (f1b843838). Corrected in the bench header and the CI step comment. The accurate point is narrower and stronger: that bench asserts `callsResolved === 0`, so it never drives the qualified-receiver path, and it is `skipIf(!GITNEXUS_BENCH)` while the only step setting that variable lists neither C++ bench — so it has never run in CI. Wiring it in is a follow-up. - "Ordering is load-bearing" was not a live property: `allHits[0]` is only reached at length 1, and both tail branches return `'ambiguous'`. Order is still preserved for byte-identity with the pre-#2788 walker; the comment now says that instead, and the test named for ordering is renamed to the parent/inline-child visibility it actually asserts. - "Same contract as `ensureAdlIndex`" overstated parity — the sibling ships a `validateAdlSeqCoverage` guard because it reads `seqByNodeId.get(...) ?? 0`, which can silently collapse candidates. This index has no analogous defaulting read, so no guard is added; the comment now says why. - Two coverage gaps closed, both mutation-verified: cross-file merge of one namespace reopened in two files (no existing test covered it — confirmed by making each file clobber the previous and watching only the new test fail), and the same-name inline nest whose dedup, when defeated, flips a resolved def to `'ambiguous'`. - `resolveCppQualifiedNamespaceMember`'s JSDoc now names both production call sites, including the callsite-less `resolveAdlCandidates` path. - Memoized candidate buckets are frozen, so a future in-place sort in `overload-narrowing.ts` throws instead of silently corrupting later resolutions now that the array is shared across call sites. - `_scaling_note`'s "measured 0.93-1.21" band did not reproduce; it is now the honestly observed 1.28-1.45, with the small arm widened to ~14ms (halves the spread) and a triage line saying a scaling failure is a timing signal to re-run, unlike the deterministic fingerprint arm. Verification: 840,000 differential probes against the pre-#2788 walker extracted from base, 0 mismatches, plus 48,000 candidate-order comparisons, 0 mismatches. cpp resolver integration suite 334/334. Unit suite 10/10. tsc, eslint, prettier clean. Bench --check PASS. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(bench): escape the NUL separator so measure.mjs stays a text file The fingerprint key separator was written as a literal NUL byte instead of the `\u0000` escape. Git classifies any file containing a NUL as binary, so the whole bench showed as `Bin` with no diff on GitHub and could not be reviewed — the same defect this branch already fixed once before the tri-review. Escaping it is byte-for-byte equivalent at runtime (both produce U+0000), so the committed fingerprint is unchanged and `--check` still passes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * refactor(cpp): quality cleanups from a four-angle review of the #2788 series Reuse, simplification, efficiency and altitude passes over the diff. No resolution behaviour changes: the bench fingerprint is unchanged and the C++ resolver integration suite still passes in full. Efficiency - The `Object.freeze` added in the review-fix commit to close an aliasing residual costs 4.6x on the narrowing path — V8 moves frozen arrays to PACKED_FROZEN_ELEMENTS, off the fast path for the `.filter`/`.map`/`.some` runs `narrowOverloadCandidates` does at every multi-candidate call site. The hazard it guards is already a compile error (both the memo and the parameter are `readonly SymbolDefinition[]`), so it is now a dev-only tripwire. Gated on `isSemanticModelValidatorEnabled()` — the repo's opt-IN form used by `phase.ts` and `validate-bindings-immutability.ts` — not `adl.ts`'s opt-out `NODE_ENV !== 'production'`, which would keep paying the cost in CLI runs where `NODE_ENV` is unset. Large bench arm 100.3 -> 70.6ms. - The index build scanned every scope in every file twice; pass 1 now collects `[scope, node]` pairs for pass 2 to iterate. 800k scopes 14.40 -> 8.21ms. - `simpleNameOf` uses `lastIndexOf('.')` + `slice` instead of `split('.').pop()` (83 -> 24 ns/call), semantics verified byte-equivalent over 12 edge cases including `undefined`, `''`, `'a.'`, `'.b'` and `'a..b'`. - The per-call `hookCtx` literal is hoisted to a module const. - The bench's fingerprint pass resolved 960k call sites to produce 5,800 distinct outcomes; it now dedups on the key it already builds. Bench wall time 2.4 -> 1.9s, fingerprint byte-identical. Reuse - `bucketOwnMembers` used an inlined `Function | Method | Constructor` compare; it now calls the canonical `isOverloadableCallable`. `graph-bridge/ids.ts` already carries a note that inlining this list recreated twin-list drift once. Altitude - `adl.ts` had the same retention defect this series just fixed next door: a module-level `let adlIndex` + `let adlIndexSource` strongly pinning the whole `parsedFiles` array until the next C++ pass, which in a single analyze never comes. Converted to the same `WeakMap` shape. Measured with `--expose-gc`: 89.11MB retained after the caller drops the array before, 0.17MB after. Six file-local helpers now take the index as a parameter; no exported signature changed. - The index's freshness depended on `clearCppInlineNamespaces()` being called from another file, guarded only by a warning paragraph. An epoch bumped in both `populateCppInlineNamespaceScopes` and the clear is now stored with the memo, so a missed clear degrades to a rebuild instead of a stale answer — confirmed by driving inline state mid-pass without the clear. Roughly line neutral, since it replaces most of the paragraph. - `test/integration/cpp-adl-benchmark.test.ts` is wired into the `GITNEXUS_BENCH` step. It is `skipIf`-gated and was absent from that step's explicit file list, so #1990's ADL emit-scaling guard had never executed in CI. It passes; ~50s added to a 25-minute job. `cpp-pipeline-benchmark.test.ts` is deliberately NOT wired: it costs 115s for guards covering generic per-language pipeline scaling that nothing here touches. Simplification - Deleted a comment referencing a `inlineChildrenByParent` map that only ever existed inside this branch's own first commit, so "the legacy map" pointed a reader at code that never shipped. - Dropped three unreachable `undefined` guards (`strict: false`, no `noUncheckedIndexedAccess`), keeping the load-bearing `visited` check. - Compressed the `rootsByReceiver` doc from 17 lines to 7 — it was the longest comment in the file and guarded the least consequential property — the `validateAdlSeqCoverage` paragraph from 7 lines to 3, and turned three restatements of the uncaught-throw and dedup arguments into pointers. - Test fixtures: dropped the dead `'Module'` union arm, added a one-line `ns()` builder for the nine hand-written scope literals, and moved the file to `test/unit/scope-resolution/cpp/` where every other C++ scope-resolution unit test lives. 403 -> 337 lines, same 10 tests, and the cross-file mutation check still fails exactly one test. Not done, and why: merging this index into `AdlCandidateIndex` (they key on different names with different inline-transparency depth — a refactor with correctness risk, not a cleanup); `ScopeTree.getChildren` (trades in-memory `parsed.scopes` for store hits on a hot path); a shared `cpp/` util for the five pre-existing `simpleName` copies; sharing fixtures across the bench/test boundary (no precedent in this repo); and an exact-count arm for the bench, which is a gate redesign worth its own change.

Gergő Magyar	911151e230	fix(resolution): resolve Go pointer-receiver calls, and report the program boundary instead of hedging (#2766) (#2782)	2026-08-01 22:42:18 +01:00
Gergő Magyar	ed8ab1c246	fix(scope-resolution): resolve callable reference flows (#2437) (#2522) ... * docs(plans): add provider-hook value-refs plan (#2437) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(plans): deepen #2437 plan to USES + property-dispatch design Design revised after prior-art research (Kythe ref vs ref/call, Joern METHOD_REF, Feldthaus field-based call graphs, CodeQL impliedReceiverStep): registration sites emit reference-class USES, invocation is recovered by a field-based property-dispatch pass synthesizing CALLS at member-call sites. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(scope-resolution): model provider-hook value references (#2437) Functions referenced as object-literal property values (provider hooks like emitScopeCaptures: emitCppScopeCaptures) previously produced no edge at all, so impact/context reported a false-safe 0 upstream dependents. Two coordinated halves, per prior art (Kythe ref vs ref/call, Joern METHOD_REF, Feldthaus ICSE'13 field-based call graphs, CodeQL impliedReceiverStep): - Registration -> USES: new ReferenceKind 'value-ref'; TS/JS queries capture pair values and shorthand properties (with @reference.property-key); emitted as a reference-class USES edge, reason 'scope-resolution: value-ref'. Resolution is callable-gated so plain values emit nothing. - Dispatch -> CALLS: new shared pass emitPropertyDispatchCalls synthesizes CALLS (reason 'property-dispatch', confidence 0.7, per-key fan-out cap 32 calibrated on this repo's 16-provider hook tables) from member-call sites to every function registered under the same property key. Deviation from plan: the pass owns value-ref resolution entirely via the post-finalize findCallableBindingInScope walker — the shared registries only see pre-finalize local bindings, so imported hooks (the c-cpp.ts case) were unresolvable through lookupForSite; Reference.propertyKey passthrough dropped as unnecessary. SCHEMA_BUMP 13 -> 14: ParsedFile gains value-ref sites + propertyKey. Verified end-to-end: impact(emitCppScopeCaptures, upstream) now reports 8 impacted / HIGH with extractParsedFile (true dispatch caller) at d=1 via property-dispatch and the c-cpp.ts registration via USES. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(scope-resolution): cover value-ref registration and property dispatch (#2437) Integration: same-file/cross-file/aliased/shorthand registrations emit USES; non-callable and destructuring values emit nothing; dispatch sites gain property-dispatch CALLS (incl. JS twins and per-language partitioning); fan-out-capped keys are dropped entirely; factory-call values unchanged. Unit: capture-shape pins for @reference.value-ref + @reference.property-key. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(scope-resolution): surface dropped property-dispatch keys in stats (#2437) Review finding: skippedKeys was returned but discarded — a hook table larger than the fan-out cap silently reopened the #2437 gap for those keys. Log dropped keys and fold value-ref USES + dispatch CALLS into referenceEdgesEmitted. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(plans): add callable reference-flow implementation plan * fix(scope-resolution): close property-dispatch review gaps * feat(scope-resolution): add callable flow facts * feat(scope-resolution): resolve callable value flow * feat(scope-resolution): resolve callable references across providers * fix: harden callable reference flow resolution * fix(scope-resolution): preserve callable binding semantics * docs(plans): add pr-2522-review-fixes plan Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(storage): bump INCREMENTAL_SCHEMA_VERSION for callable-value-flow edges Callable-value-flow CALLS/USES edges (#2437) can connect two files whose content did not change, but the incremental write set only covers changed files — a top-up against a pre-v7 index would silently omit the new edges for every unchanged file pair, indefinitely. Force the one-time full re-analyze (review finding 1, #2522). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(storage): sanitize callable-flow sites per-site at load, log drops The load-time validator rejected the WHOLE ParsedFile when one site was malformed or over-bound, with no logging — and C++ legitimately emits empty-string parameterTypes entries ('' = unknown, the ReferenceSite.argumentTypes convention) for cv-only/ERROR-recovered types, so real repos fell into a permanent, silent warm-cache-miss reparse loop through the #1983-sensitive main-thread path (review finding 7, #2522). Now: '' entries are valid in type arrays; a malformed/over-bound site drops only itself (counted, warned once per load); only non-array garbage — evidence the serialization itself is untrustworthy — rejects the file. Deviation from plan §6 wording: validator-side tolerance replaces emit-side clamps — smaller diff, same asymmetry closed at the single chokepoint. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(scope-resolution): keep declarations in the union for reassigned callable cells The binding-lookup suppression for fact-constrained cells was wholesale: reassigning a declared function through its own name (greet = other; greet()) deferred the call to the solver, which then refused the lexical lookup that resolves the declaration — an unresolvable RHS yielded zero CALLS for a call that resolved pre-flow (review finding 8, #2522). Suppression now applies only to cells bound by FORMAL facts — its actual purpose (a parameter whose grammar emits no declaration binding must not adopt a same-named outer function). Copy/alias/store/load destinations keep their declaration as an inclusion seed (Andersen-style union). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(scope-resolution): count forfeited deferred sites in the budget-bailout warning On work-budget exhaustion the deferred invoke sites end the run with zero CALLS — free-call fallback and reference emission already skipped them — but the warning said 'ordinary graph emission remains untouched', which is false for exactly those sites. The warning context now carries the unresolved deferred-site count and the comment states the real cost (review finding: budget-bailout honesty, #2522). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(scope-resolution): surface dropped property-dispatch keys in stats and warn payload The over-cap warning carried only a count; the dropped key NAMES were discarded and RunScopeResolutionStats had no field, so the PR-body claim 'includes them in resolver statistics' was unimplemented (review finding, #2522; reviewer ask on the fan-out cap). The warn payload now names up to 20 dropped keys and the stats carry propertyDispatchSkippedKeys. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(scope-resolution): drop producer-less ownerQualifiedName from formal sites No capture emitter anywhere produces @callable-flow.owner-qualified-name — the solver branch consuming it was unreachable in production, yet the field was typed, parsed, validated, and unit-tested with hand-built input (review finding 16, #2522; YAGNI). Re-add with a real producer if C++ qualified member declarators ever need it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(scope-resolution): drop dead callable-flow knobs CallableFlowPassingMode 'callable-object' had no producer and no consumer distinguishing it, and CallableFlowCaptureOptions.extractCallArguments had no language providing it (unlike its live sibling extractCallCallee) — review finding 17, #2522 (YAGNI). The invocation-kind 'callable-object' is a different, live concept and stays. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): bind subscripted callable cells to the container, not the index terminalIdentifier iterates children in reverse, so tbl[i] = handler seeded the INDEX variable's cell (polluting a same-named formal) and tbl[i](7) looked up the callee under i in a different scope — no join, no CALLS edge for the classic function-pointer-array dispatch (review finding 12, #2522). Subscript nodes now recurse into their container field only, in both bindingIdentifier and terminalIdentifier, across the fielded grammars (C/C++/JS/TS/Python/Go/Java). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): make cross-function file-scope callable bindings resolvable Two stacked gaps killed the canonical C callback-registration pattern (fp assigned in init(), called in run()) — the exact #2437 false-safe this PR exists to fix (review finding H1, #2522): 1. isVisibleValueBinding only consulted assignment regions and formals, so a call in a function OTHER than the assigning one emitted no invoke fact. A declared callable-typed binding is now a value binding wherever its declaration is visible (visibleCallableSignature). 2. The C scope query had no @declaration.variable pattern for function- pointer declarators — void (*fp)(int); created no scope-tree binding, so the seed (init) and invoke (run) cells canonicalized to different keys and never joined. Both bare and initialized forms now bind. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(c): detect variadic parameters via the named variadic_parameter node tree-sitter-c materializes '...' as a named variadic_parameter node; the anonymous-token checks never matched, so variadic function-pointer signatures were emitted with a wrong fixed arity and no '...' sentinel (review finding, #2522). C++ is unaffected ('...' stays an anonymous token there); the token checks remain for such grammars. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): emit invoke facts for field-stored callable member calls The C ops-vtable pattern (o->run = handler; o->run(1)) captured the store but never the call — the member path in emitCallFacts bailed for languages without protocol methods, and the value-binding index recorded the member store under the OBJECT's name ('o'), not the member's ('run') (review finding 11/M3, #2522). Member destinations now also record their terminal member name, and a member call whose name-cell has a visible store emits an indirect invoke — gated on the store so plain accessor calls (map.get) stay inert. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): disambiguate (obj->*ptr)() ERROR recovery by token order tree-sitter-cpp groups the recovered '->*' two ways depending on error-recovery cost (identifier lengths): [identifier, ERROR '->*m'] or [ERROR 'obj->*', identifier]. The recovery assumed the first shape, so the second silently swapped receiver/member and dropped the call site — the committed test passed only by name luck (review finding H2, #2522). The identifier's position relative to '->*' inside the ERROR now decides roles. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): class members are never file-local in hasFileLocalCallableLinkage The name-keyed file-local set is populated from every static declaration, so an in-class 'static void make();' (external linkage — in-class static means no-instance) and any member sharing a name with a static free function were over-marked, refusing legitimate cross-file declaration/definition joins (review finding 13/M2, #2522). Method and Constructor defs now bypass the name-set, per the hook's own linkage-only contract. Deviation from plan step 13: the regression is a unit-level contract pin rather than an end-to-end join test — C++ merges out-of-line member definitions onto the member node by qualified identity, so the graph shape cannot discriminate the join refusal for members. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): classify parameter passing mode from the declarator chain only A whole-subtree scan for reference_declarator inverted copy vs alias: void reg(void (*cb)(int& out)) marked the by-value pointer cb as 'reference' because of the NESTED parameter's int&, making the solver back-propagate formal targets into every caller's argument cell — alias semantics for a copy (review finding 14/M5, #2522). The chain walk never descends into nested parameter lists; a reference anywhere ON the chain (int& x, void (*&cb)(int)) still aliases. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ruby): bare identifiers are calls, not callable references Ruby parses a receiver-less zero-arg method call identically to a variable read, so 'action = process' — which CALLS process and stores its return — seeded action with the callable and minted a wrong CALLS edge from any dispatch through it, confirmed end-to-end (review finding 15/HIGH, #2522). New provider knob bareNamesAreCalls: a bare name that is not a provably local value binding and not an explicit reference form (method(:x), lambda/proc) emits no flow fact, on both the assignment and argument paths. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(go): pair multi-value := positionally instead of cross-wiring The shared field fallback took the FIRST LHS identifier and the LAST RHS identifier of Go's expression_list pair, cross-wiring 'a, b := f, g' and synthesizing a garbage comma-joined qualified name — the real relationships were silently dropped (review finding 16, #2522). extractAssignment may now return multiple pairs; Go pairs list entries positionally and emits nothing for a length mismatch (multi-return call RHS). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(java): drop get/test from callableProtocolMethods 'get' and 'test' collide with ubiquitous non-functional-interface APIs (Map/List/Optional/Future.get), so every ordinary container access emitted a spurious callable-object invoke fact — high-volume misleading graph facts with a cross-wiring risk on receiver-name reuse (review finding 17, #2522). Supplier.get/Predicate.test dispatch is deliberately traded away until the check can gate on the receiver's declared type. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(rust): pin the qualified-name no-degrade guard as a hard invariant Rust's scoped_identifier callable-reference capture over-includes unit enum variants and associated constants (Shape::Square seeds as if callable); they stay edge-free only because resolveSeedCandidates refuses to degrade an unresolved qualified name to a simple-name lookup (review finding 18, #2522). Capture-side type filtering would false-negative on tuple-variant constructors, so the guard IS the contract: documented as a hard invariant (Go's mis-shaped multi-value forms also rely on it) and pinned end-to-end. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(php): remove nonexistent optional_parameter node type tree-sitter-php has no 'optional_parameter' — defaults ride on simple_parameter — so the entry was dead weight the #1920 literal gate does not cover for capture-option Sets (review finding 19, #2522). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cobol): detect procedure pointers on fixed-format sources Two stacked defects made the feature a no-op on classic sequence-numbered fixed format (review finding 20/H3, #2522): 1. parseDataItemClauses' USAGE alternation knew POINTER but not PROCEDURE-POINTER/FUNCTION-POINTER, so the dataItems filter was dead. 2. The raw-line fallback scanned UNCLEANED text, where the sequence number satisfied the leading digits and the LEVEL NUMBER got captured as the pointer name. It now scans preprocessed lines and requires a letter- initial name (COBOL data names must contain a letter). 161 COBOL preprocessor/copy-expander tests stay green; free-format matrix case unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cobol): skip comment lines in SET seed/copy scans A commented-out SET (indicator-column '*'/'/' or free-format '*>') produced a live seed and a false CALLS edge from dead code (review finding 21/M1, #2522). The scan now skips indicator-column comment lines and strips inline '*>' tails before matching. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(architecture): document callable-flow-only mode and skipped-key reporting The Callable-value flow section omitted scopeResolutionEdgeMode: 'callable-flow-only' — a real emit-pipeline branch that suppresses all ordinary emission for standalone providers (review finding 22, #2522) — and predated the skipped-key names/stats surfacing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(scope-resolution): correct value-ref resolution attribution and stale pdg-gating comments The value-ref contract comment claimed MethodRegistry resolution — the mechanism is the post-finalize findCallableBindingInScope walker owned by emitPropertyDispatchCalls (resolveReferenceSites skips these sites). Three 'only under --pdg' calleeIdSink comments were falsified by the #2437 gating change (callee-id-sink.ts's header was updated; these copies were missed). Review finding 23, #2522. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(ingestion): direct unit coverage for synthesizeCallableFlowCaptures The 1,100-line shared synthesizer had no test naming it — only downstream consumers were covered (review finding 24, #2522). Pins seed/invoke/ formal/argument emission, subscript container binding, store-gated member invokes, produced-value guards, and the bareNamesAreCalls knob over a minimal options object so assertions target the synthesizer's own semantics. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(resolvers): deepen shallow-language coverage; fix Kotlin/Swift reassignment gaps it exposed Adds the COBOL SET x TO y copy-branch scenario and conditional-assignment scenarios for Kotlin, C#, Swift, and Dart (10 languages previously had one generic case each — review finding 25, #2522). The new scenarios exposed two real capture gaps, fixed here: - tree-sitter-kotlin's 'assignment' node is fieldless, so nested reassignments (chosen = ::target inside a block) produced no flow facts; Kotlin's extractAssignment now decomposes it positionally. - tree-sitter-swift fields its assignment as target:/result:, neither in the shared fallback's field lists; both added. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(infra): literal-validation gate for callable-capture option Sets The #1920 gate validates query literals and exported configs but not the module-private *_CALLABLE_CAPTURE_OPTIONS Sets consumed by the shared synthesizer — a typo'd node type silently captures nothing (PHP shipped a dead 'optional_parameter'; review finding 26, #2522). Every <key>NodeTypes Set literal is now validated against its language's grammar; name-carrying sets (callableProtocolMethods, memberPointerOperators) are deliberately outside the contract. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(storage): centralize corrupt-fixture casts into makeStoreEntry The callable-flow store tests scattered 'as unknown as' double-casts per fixture (review finding 27, #2522; standing no-as-any rule). One typed helper now owns the single controlled escape hatch for building malformed serialization-boundary payloads. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(bench): refresh capture fingerprints after review fixes python-scope: the committed baseline (8d5c3699) never matched this branch's code — CI's benchmarks arm was red on the PR head (review finding 2/HIGH, #2522); regenerated (a99e69ab), scaling 1.04 in budget. scope-capture: ruby/cpp/swift/java/kotlin drifted from the review-fix commits (bare-name suppression, passing modes + ->* recovery, assignment fields, protocol narrowing, positional assignment); all 14 languages re-verified PASS with ratios <= 1.18 against the 1.5 budget. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore(docs): untrack docs/plans working documents docs/ is gitignored (local working docs); the plan files were force-added past the ignore. Untracked from the index only — they stay on disk. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(golden): regenerate captures goldens after callable-flow review fixes The per-language digest guards (csharp/go/php/python/ruby/rust/swift) locked the pre-fix capture output; the review-fix series intentionally changed it — store-gated member invokes, subscript container binding, Ruby bare-name suppression, Swift assignment fields, positional pairing. Regenerated with UPDATE_GOLDEN=1; clean verification run 59/59; all other parity/golden guards (pipeline-graph, spring-route, python parity) pass untouched at 33/33. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ingestion): prototypes are callees, not callable value cells The cross-function visibility fix indexed EVERY signature-bearing declaration as a value binding — including plain function/method prototypes (void f(int);). Every call to a declared function then became an indirect invoke, and with emitCanonicalInvokeReference (C/C++) minted a free-call reference that resolved through the registry, bypassing the precise passes' two-phase/ambiguity/subobject suppression — eight phantom CALLS edges in the cpp resolver suite on CI. Only declarations whose binding identifier sits under a pointer/ parenthesized declarator (callable-typed variables like void (*fp)(int);) create value cells now. cpp resolver suite 331/331; callable-value-flow + C/C++ suites 181/181 (the cross-function fp regression still passes); cpp fingerprint rebaselined, both bench gates PASS.

Gergő Magyar	f1b8438388	perf(cpp): index ADL candidates once instead of per-site rescans (#1990) ... * perf(cpp): index ADL candidates once instead of per-site rescans C++ scope-resolution `emit` dominated large-repo analysis (~6.76h on a 5,969-file repo — ~70% of the total run). `pickCppAdlCandidates` ran once per unresolved ADL-eligible call site and each time: - rescanned every parsed file (rebuilding a per-file scope map per call), - scanned every workspace def (`findCppClassDefBySimpleName`), and - used an O(scopes²) child-scope walk for hidden friends. That is O(unresolved sites × files); with hundreds of thousands of unresolved C++ sites the emit phase went super-linear. `resolve` (registry lookup) was only 3.5s — the cost was entirely in fallback edge emission. Build an `AdlCandidateIndex` once per run (lazy, guarded by `parsedFiles` identity, reset in `clearCppAdlState`) and query it per site: - `classDefsBySimple` — preserves `defs.byId` order so first-match / ambiguous semantics are identical to the legacy linear scan. - `nsCandidates` — namespace-owned callables, with inline-namespace transparency. - `friendCandidates` — hidden-friend + class-member callables; a parent→children scope index replaces the O(scopes²) walk. - `nsFunctionsByQName` / `nsFunctionsBySimple` — function-reference ADL path. A monotonic `seqByNodeId` (file-major; namespace defs before friend/member defs within a file) lets the per-site query merge candidates across associated namespaces, dedup by nodeId, and sort — reproducing the exact legacy candidate set and order. Per-site cost drops from O(sites × files) to O(associated namespaces); the emit phase goes from linear-in-sites to flat. Benchmark (files=80): emit at 1000 sites 232ms → 9ms, 2000 sites flat at 17ms; the eliminated term scales with file count, so the speedup is ~1000×+ on the real 5,969-file repo. Behavior is unchanged: synthetic candidate output is byte-identical before/after, all 270 C++ integration resolver tests and 4/4 resolver-parity-expected-failures pass, and tsc + eslint are clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(cpp): correct ADL state-lifecycle and cache-guard comments The header lifecycle block listed three module-level maps and named clearFileLocalNames as the reset caller; both became inaccurate when the candidate index was added. Enumerate all five state pieces, name the real caller (loadResolutionConfig), and document that ensureAdlIndex's staleness guard keys on parsedFiles identity while the index also depends on scopes and classToNamespaceQualifiedName. Addresses PR #1990 tri-review (U1, U3). Doc-only; no behavior change. * test(cpp): guard the ADL seq-coverage invariant in dev/test pickCppAdlCandidates sorts merged candidates by seqByNodeId with a `?? 0` fallback. That fallback is unreachable today (every bucketed def is seq-assigned in the same build block), but a future regression could break it and silently collapse two seq-0 candidates, dropping a CALLS edge with no error. Add validateAdlSeqCoverage and run it from buildAdlIndex under the resolver's opt-in validation gate (NODE_ENV!=production && VALIDATE_SEMANTIC_MODEL!=0), so a broken invariant throws loudly in dev/CI instead. Production behavior and the hot path are unchanged. Unit-tested; 270/270 cpp integration tests pass with the guard active. Addresses PR #1990 tri-review (U2). * test(cpp): parity fixture for ADL hidden-friend + namespace-callable merge pickCppAdlCandidates merges friendCandidates (hidden friends of associated classes) and nsCandidates (namespace-owned callables) for a single associated namespace. The byte-identical-parity claim rested only on an uncommitted harness. Add a fixture that reaches one callable through each bucket — combine only via a hidden friend, process only via a namespace member — so dropping either bucket from the merge fails the suite. Candidate order is not observable (narrowing resolves a unique survivor or suppresses), so the guard is on the set. Addresses PR #1990 tri-review (U4). * test(cpp): add ADL emit-scaling benchmark Guards the PR #1990 optimization against reintroducing the O(sites x files) ADL candidate scan. Generates many UNRESOLVED ADL sites (class-typed arg + a callee declared nowhere) and co-scales files and sites with N, so the old cost is O(N^2) and the new cost O(N). Isolates the scope-resolution emit ms from parse-dominated wall time via the logger test destination (capture verified) and asserts the end-to-end emit ratio stays under fileRatio^1.5. Gated by GITNEXUS_BENCH=1; runs build-free (workerPoolSize: 0). Addresses the benchmark request alongside PR #1990 (U5). * test(cpp): add cpp pipeline file-count benchmark Fills the one missing per-language pipeline benchmark (cobol/csharp/go/php/ ruby/rust already have one); modeled on cobol-pipeline-benchmark.test.ts. Generates synthetic C++ with constant per-file work and constant header fan-out, sweeps file count through the full pipeline, and guards linearity with a coarse time-ratio bound plus a deterministic node-ratio bound (the non-flaky guard against reintroducing O(fileCount^2) work). Gated by GITNEXUS_BENCH=1; runs build-free (workerPoolSize: 0). Addresses the benchmark request alongside PR #1990 (U6). * style(cpp): prettier-format adl benchmark * test(cpp): rebaseline scope-capture fingerprint for new ADL fixture The U4 parity fixture (cpp-adl-ns-plus-hidden-friend-same-name) lives under test/fixtures/lang-resolution/cpp-*, so its lib.h + app.cpp join the cpp scope-capture bench corpus (bench/scope-capture/measure.mjs). That is pure fixture-corpus growth — no scope-extractor change, existing fixtures' captures byte-identical — so the cpp fingerprint legitimately drifts (fixture_count 265->267). Rebaseline cpp to match, as #1965/#1975 did for earlier fixture additions. Verified: --check PASS for all 14 languages.

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). --------- Co-authored-by: HuangWenjie <zhoudeng.hwj@alibaba-inc.com> Co-authored-by: Gergo Magyar <gergomagyar@icloud.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>	2026-05-14 09:30:52 +01:00
