From e412d292fe4c9639094b91ae30839391ecbd80f6 Mon Sep 17 00:00:00 2001 From: Copilot <198982749+Copilot@users.noreply.github.com> Date: Mon, 11 May 2026 09:02:00 +0100 Subject: [PATCH 01/57] feat: migrate C to scope-based resolution (RFC #909 Ring 3) (#1481) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Initial plan * feat: add C scope resolution files for language migration (RFC #909) Add 11 C language scope resolution files following the Go pattern: - query.ts: tree-sitter-c query and parser for C constructs - captures.ts: emit scope captures with arity enrichment - import-decomposer.ts: decompose #include into structured captures - arity-metadata.ts: C function declaration/call arity computation - interpret.ts: interpret C imports and type bindings - import-target.ts: resolve #include paths via suffix matching - arity.ts: C arity compatibility (variadic detection) - merge-bindings.ts: first-wins binding merge by tier - simple-hooks.ts: null hooks (no receivers/methods in C) - index.ts: barrel re-exports - scope-resolver.ts: ScopeResolver implementation for C Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * feat: migrate C to scope-based resolution (RFC #909 Ring 3) Add C ScopeResolver with: - tree-sitter-c scope query (structs, unions, enums, functions, macros, variables, includes) - emitCScopeCaptures with arity enrichment and typedef-struct dedup - interpretCImport for #include directives (system headers filtered) - resolveCImportTarget with suffix matching - cArityCompatibility with variadic detection - cMergeBindings (first-wins by tier) - Header file scanning for cross-language #include resolution - Register in SCOPE_RESOLVERS and MIGRATED_LANGUAGES -

Add static-linkage.ts tracking module with markStaticName/isStaticName/expandCWildcardNames - Update captures.ts to detect storage_class_specifier static on functions - Wire expandsWildcardTo in scope-resolver.ts Finding 2: Expand test coverage to ≥30 cases (74 unit tests added) - c-captures.test.ts: 55 tests (scopes, structs, unions, enums, functions, typedef, field, variable, macro, imports, references, type bindings, arity, static) - c-imports.test.ts: 12 tests (decomposition, interpretation, target resolution, determinism, edge cases) - c-arity.test.ts: 18 tests (declaration arity, call arity, compatibility) Finding 3: Deterministic #include resolution on depth ties - Add lexicographic tiebreak in import-target.ts when candidates tie on path depth Finding 4: Revert unexplained package-lock.json change - Restored to pre-PR state (node >=20.0.0) Finding 5: Planning artifact commit acknowledged (squash on merge) Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/22ee780c-2b44-4e69-b9c4-8843ad6ec1ee Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * fix: address code review feedback — Set-based dedup, SyntaxNode type alias Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/22ee780c-2b44-4e69-b9c4-8843ad6ec1ee Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * chore(autofix): apply prettier + eslint fixes via /autofix command * fix: address second review findings 1-4 — isFileLocalDef hook, singleton docs, fn-ptr typedef, static isolation test Finding 1: Added `isFileLocalDef` hook to ScopeResolver contract + implementation in free-call-fallback.ts to filter C static functions from global free-call fallback. Threads caller filePath through pickUniqueGlobalCallable so static defs in other files are excluded. Finding 2: Documented single-invocation assumption on staticNames Map. Added clearStaticNames() call in loadResolutionConfig to prevent cross-repo contamination in server-mode scenarios. Finding 3: Added tree-sitter query pattern for function pointer typedef aliases (typedef void (*callback)(int, int)) in query.ts. Added unit test. Finding 4: Added c-static-isolation integration fixture (a.c with static helper, b.c with non-static helper, caller.c) and test asserting no CALLS edge from caller to a.c's static helper. Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/5b948327-9f59-4ca2-9d8c-8c8087feb510 Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> * chore(autofix): apply prettier + eslint fixes via /autofix command * fix: skip static isolation integration test in legacy parity mode The `caller.c calls b:helper via include, NOT a:static helper` test requires scope-based wildcard import binding + isFileLocalDef filtering which is only available in the registry-primary path. The legacy DAG path does not resolve cross-file calls through #include → prototype chains. Added to LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.

Finding 2: Expand scanHeaderFiles skip list with dist, build, out, target, _build, .next, cmake-build-* to avoid generated headers shadowing source ones. Finding 3: Implement same-directory sibling preference in resolveCImportTarget, matching C compiler #include "…" relative-lookup semantics. Sibling check now runs before exact match and suffix fallback. Tests: 11 new header-scan tests, 4 new import-target tests (96 total C tests).

Normalize output with .replace(/\\/g, '/') matching the convention used throughout the scope-resolution pipeline.

Distinguishes from explicit `int foo(void)`. 3 unit tests cover K&R definition, prototype, and void comparison. Finding 2: Added code comment documenting function-pointer-variable call capture as known architectural trade-off (same as Go resolver). Finding 3: Added code comment documenting prototype/definition duplication as graph-quality concern (no false CALLS edges). Finding 4: Renamed `_filePath` → `filePath` in captures.ts since it is actively used in markStaticName().

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(server): sanitize repo name to prevent argument injection Sanitizes the extracted repository name to prevent argument injection during git clone operations and ensures compatibility with various file systems. 1. Strips leading dashes to prevent git command-line argument injection. 2. Replaces unsafe directory characters with underscores. 3. Blocks path traversal segments ('.' and '..') and Windows reserved names. 4. Fixes ReDoS vulnerability in parseRepoNameFromUrl regex. 5. Added unit tests for sanitization and path traversal edge cases. * fix(server): expand Windows reserved name check to include extensions - Updated sanitizeRepoName to block Windows reserved names (CON, NUL, etc.) even when they have extensions (e.g., CON.txt). - Corrected regex and added unit tests for these edge cases to resolve CI failures on Windows. - Ref: https://github.com/abhigyanpatwari/GitNexus/pull/1305#issuecomment-4407200914 --------- Co-authored-by: Gergő Magyar --- gitnexus/src/server/git-clone.ts | 26 ++++++------ gitnexus/src/storage/git.ts | 63 ++++++++++++++++++++++------ gitnexus/test/unit/git-clone.test.ts | 40 ++++++++++++------ gitnexus/test/unit/git.test.ts | 59 ++++++++++++++++++++++++++ 4 files changed, 149 insertions(+), 39 deletions(-) diff --git a/gitnexus/src/server/git-clone.ts b/gitnexus/src/server/git-clone.ts index 861a16648..0ced1213a 100644 --- a/gitnexus/src/server/git-clone.ts +++ b/gitnexus/src/server/git-clone.ts @@ -11,6 +11,7 @@ import os from 'os'; import fs from 'fs/promises'; import { isIP } from 'net'; import { logger } from '../core/logger.js'; +import { parseRepoNameFromUrl } from '../storage/git.js'; /** Root directory for all cloned repositories.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(embeddings): forward GITNEXUS_EMBEDDING_DIMS as dimensions in HTTP request body When GITNEXUS_EMBEDDING_DIMS is set, include it as the `dimensions` field in the /v1/embeddings request body. This enables Matryoshka-capable models (OpenAI text-embedding-3-*, Cohere embed-v3, Voyage) to return truncated vectors at the requested size. When the env var is unset, the request body remains `{ input, model }` — no breaking change for backends that reject unknown fields. Adds 4 unit tests covering both paths (with/without dimensions) on both the batch embed and single-query embed code paths. * fix(embeddings): address review findings — strict parseInt, multi-batch test, comment wording 1. Strict parseInt validation: reject non-numeric strings like '1024abc' by checking /^\d+$/ before parseInt (Finding 1). 2. Add multi-batch test asserting dimensions is forwarded in every fetch call when inputs exceed batch size (Finding 2). 3. Soften JSDoc comment: backends may ignore or reject the dimensions field rather than universally ignoring it (Finding 3). 4. Add test for invalid GITNEXUS_EMBEDDING_DIMS values. --------- Co-authored-by: henry Co-authored-by: Gergő Magyar --- gitnexus/src/core/embeddings/http-client.ts | 42 +++++++- gitnexus/test/unit/http-embedder.test.ts | 112 ++++++++++++++++++++ 2 files changed, 149 insertions(+), 5 deletions(-) diff --git a/gitnexus/src/core/embeddings/http-client.ts b/gitnexus/src/core/embeddings/http-client.ts index e3fb06045..e8e9073ff 100644 --- a/gitnexus/src/core/embeddings/http-client.ts +++ b/gitnexus/src/core/embeddings/http-client.ts @@ -40,8 +40,11 @@ const readConfig = (): HttpConfig | null => { const rawDims = process.env.GITNEXUS_EMBEDDING_DIMS; let dimensions: number | undefined; if (rawDims !== undefined) { + if (!/^\d+$/.test(rawDims)) { + throw new Error(`GITNEXUS_EMBEDDING_DIMS must be a positive integer, got "${rawDims}"`); + } const parsed = parseInt(rawDims, 10); - if (Number.isNaN(parsed) || parsed <= 0) { + if (parsed <= 0) { throw new Error(`GITNEXUS_EMBEDDING_DIMS must be a positive integer, got "${rawDims}"`); } dimensions = parsed; @@ -91,7 +94,13 @@ interface EmbeddingItem { * @param model - Model name for the request body * @param apiKey - Bearer token (only used in Authorization header) * @param batchIndex - Logical batch number (for error context) - * @param attempt - Current retry attempt (internal) + * @param dimensions - Optional output-vector size.

This is problematic for bulk indexing operations on read-only mirrors or third-party repos. Add two new flags: - `--skip-skills`: suppress standard GitNexus skill file injection - `--index-only`: pure index mode that suppresses all file injection (AGENTS.md, CLAUDE.md, and skills), writing only to `.gitnexus/` This gives users three levels of control: - `--skip-agents-md` — suppress only root context files - `--skip-skills` — suppress only skill injection - `--index-only` — suppress everything (pure indexing) Discovery context: while bulk-indexing 176 repos with `--skip-agents-md`, all 144 indexed repos were contaminated with `.claude/skills/gitnexus/` files requiring manual cleanup. * fix(cli): address PR #742 review — gate community skills, drop dangling refs, add tests Bot review (#742) flagged three issues with the original commit: 1. `--index-only --skills` still wrote community-derived skill files to `.claude/skills/generated/`. The `--skills` branch in analyze.ts was not gated by `skipAll`, so the "skip all file injection" contract was violated. Gate `generateSkillFiles()` with `!skipAll` so `--index-only` truly wins over `--skills`. 2. `--skip-skills` without `--skip-agents-md` produced AGENTS.md / CLAUDE.md that still referenced `.claude/skills/gitnexus/*/SKILL.md` files that were never installed — every agent load incurred 6 failed reads. Pass `skipSkills` through to `generateGitNexusContent()` and omit the standard-skill rows (and the entire `## CLI` heading when the table is empty). Community skills, when present via `--skills`, are unaffected. 3. No filesystem tests for `skipSkills` / `indexOnly`. Add three regression guards to `test/unit/ai-context.test.ts`: - `.claude/skills/gitnexus/` is NOT created when skipSkills=true - Nothing is written when both skipAgentsMd and skipSkills are true (the resolved-flag state from --index-only) - AGENTS.md/CLAUDE.md routing table omits standard skill references when skipSkills=true, but preserves the load-bearing imperative sections (Always Do / Never Do / Resources) * test(cli): PR 1485 review follow-ups (help text, gate test, --skip-skills docs) - Assert --skip-skills and --index-only in analyze --help (skip-git-cli.test.ts). - Export shouldGenerateCommunitySkillFiles; unit-test index-only+skills gate. - Clarify --skip-skills does not suppress --skills community files; --index-only for full skip. Co-authored-by: Cursor * fix(cli): warn when --index-only silently overrides --skills Address review findings on PR 1485 follow-ups: - analyze.ts emits a one-line note when both --index-only and --skills are set, so users see why a pipeline re-index ran with no skill files written. - index.ts --skills help text now flags the --index-only override. - shouldGenerateCommunitySkillFiles JSDoc documents the dual role of the gate (community skills + AGENTS.md/CLAUDE.md re-generation). - skip-git-cli.test.ts pins the override-warning surface end-to-end. --------- Co-authored-by: Gergő Magyar Co-authored-by: Cursor --- gitnexus/src/cli/ai-context.ts | 43 +++++++-- gitnexus/src/cli/analyze.ts | 48 +++++++++- gitnexus/src/cli/index.ts | 13 ++- gitnexus/src/core/run-analyze.ts | 8 +- gitnexus/test/unit/ai-context.test.ts | 95 +++++++++++++++++++ .../analyze-community-skills-gate.test.ts | 27 ++++++ gitnexus/test/unit/skip-git-cli.test.ts | 32 +++++++ 7 files changed, 250 insertions(+), 16 deletions(-) create mode 100644 gitnexus/test/unit/analyze-community-skills-gate.test.ts diff --git a/gitnexus/src/cli/ai-context.ts b/gitnexus/src/cli/ai-context.ts index 41ba6c73e..8e18fed7d 100644 --- a/gitnexus/src/cli/ai-context.ts +++ b/gitnexus/src/cli/ai-context.ts @@ -28,6 +28,7 @@ interface RepoStats { export interface AIContextOptions { skipAgentsMd?: boolean; noStats?: boolean; + skipSkills?: boolean; } const GITNEXUS_START_MARKER = ''; @@ -94,6 +95,7 @@ function generateGitNexusContent( generatedSkills?: GeneratedSkillInfo[], groupNames?: string[], noStats?: boolean, + skipSkills?: boolean, ): string { const generatedRows = generatedSkills && generatedSkills.length > 0 @@ -105,14 +107,26 @@ function generateGitNexusContent( .join('\n') : ''; - const skillsTable = `| Task | Read this skill file | -|------|---------------------| -| Understand architecture / "How does X work?" | \`.claude/skills/gitnexus/gitnexus-exploring/SKILL.md\` | + // Standard skill rows reference files installed by installSkills().

FTS indexes cannot be created in read-only mode, so searchFTSFromLbug returns ftsAvailable=false and an empty results array. The existing early-return path silently produced no enrichment. Add a Cypher name CONTAINS fallback that fires only when ftsAvailable is false and BM25 produced no symbol matches. This covers the read-only DB case (concurrent MCP server) and the first-run case (indexes not yet built). The fallback is wrapped in .catch(() => []) and cannot throw. When FTS indexes exist, this branch is never reached — behaviour is unchanged for users without a concurrent MCP server. * fix(augment): guard against CONTAINS '' and add no-FTS test coverage Blocker 1 — CONTAINS '' on whitespace-leading patterns: pattern.split(/\s+/)[0] returns "" when the input has leading whitespace (e.g. " ".split(/\s+/) → ["", ""]). In Kuzu, CONTAINS '' matches every node with a name property, injecting arbitrary graph nodes into LLM context. Fix: trim() before split, then guard on !firstWord || firstWord.length < 2. No behaviour change for normal non-empty patterns. Blocker 2 — zero test coverage on the FTS-unavailable code path: The new CONTAINS fallback block (engine.ts lines 146-166) was exercised by no existing test — all existing tests run with FTS indexes built. A second withTestLbugDB fixture is added with no ftsIndexes, forcing searchFTSFromLbug to return ftsAvailable: false, and asserts: 1. augment('login', ...) returns non-empty enrichment (fallback works) 2. augment(' ', ...) returns '' (CONTAINS '' guard holds) 3. augment('nxyz_notfound', ...) returns '' (no matching nodes) 4. executeQuery throwing returns '' (.catch(() => []) path) * fix(augment): extend CONTAINS '' guard to FTS happy path and consolidate The same split(/\s+/)[0] bug existed at line 125 (BM25 symbol filter, FTS-available path) — a leading-whitespace pattern produced CONTAINS '' there too, matching every node in BM25-matched files. Fix: hoist patternFirstWord computation with trim() and the length guard to the top of augment(), before any DB interaction. Both CONTAINS sites (BM25 symbol filter and CONTAINS fallback) now use the single pre-validated value. No behaviour change for normal patterns; the guard fires once for all callers instead of being duplicated. Also tighten the whitespace test in the no-FTS suite from 3 spaces to 4 spaces so it unambiguously exercises the patternFirstWord guard rather than straddling the outer pattern.length < 3 boundary. * test(augment): negative-safety test for ftsAvailable=true gate Asserts the CONTAINS fallback does NOT fire when FTS is available but BM25 returns zero results. Pins the safety property promised by the PR description: behavior is unchanged for users without the read-only-DB condition. If anyone later loosens the gate to `symbolMatches.length === 0` alone, this test fails. --------- Co-authored-by: Gergő Magyar --- gitnexus/src/core/augmentation/engine.ts | 32 ++++++- .../test/integration/augmentation.test.ts | 85 +++++++++++++++++++ 2 files changed, 113 insertions(+), 4 deletions(-) diff --git a/gitnexus/src/core/augmentation/engine.ts b/gitnexus/src/core/augmentation/engine.ts index 42087e4b0..81e41077e 100644 --- a/gitnexus/src/core/augmentation/engine.ts +++ b/gitnexus/src/core/augmentation/engine.ts @@ -86,6 +86,9 @@ async function findRepoForCwd(cwd: string): Promise<{ export async function augment(pattern: string, cwd?: string): Promise { if (!pattern || pattern.length < 3) return ''; + const patternFirstWord = pattern.trim().replace(/'/g, "''").split(/\s+/)[0]; + if (!patternFirstWord || patternFirstWord.length < 2) return ''; + const workDir = cwd || process.cwd(); try { @@ -104,9 +107,7 @@ export async function augment(pattern: string, cwd?: string): Promise { } // Step 1: BM25 search (fast, no embeddings) - const { results: bm25Results } = await searchFTSFromLbug(pattern, 10, repoId); - - if (bm25Results.length === 0) return ''; + const { results: bm25Results, ftsAvailable } = await searchFTSFromLbug(pattern, 10, repoId); // Step 2: Map BM25 file results to symbols const symbolMatches: Array<{ @@ -124,7 +125,7 @@ export async function augment(pattern: string, cwd?: string): Promise { repoId, ` MATCH (n) WHERE n.filePath = '${escaped}' - AND n.name CONTAINS '${pattern.replace(/'/g, "''").split(/\s+/)[0]}' + AND n.name CONTAINS '${patternFirstWord}' RETURN n.id AS id, n.name AS name, labels(n)[0] AS type, n.filePath AS filePath LIMIT 3 `, @@ -143,6 +144,29 @@ export async function augment(pattern: string, cwd?: string): Promise { } } + // When FTS indexes are unavailable (read-only DB, first run before indexes are built), + // fall back to a direct name CONTAINS query so enrichment still works. + if (symbolMatches.length === 0 && !ftsAvailable) { + const fallbackRows = await executeQuery( + repoId, + ` + MATCH (n) + WHERE n.name CONTAINS '${patternFirstWord}' + RETURN n.id AS id, n.name AS name, labels(n)[0] AS type, n.filePath AS filePath + LIMIT 5 + `, + ).catch(() => []); + for (const sym of fallbackRows) { + symbolMatches.push({ + nodeId: sym.id || sym[0], + name: sym.name || sym[1], + type: sym.type || sym[2], + filePath: sym.filePath || sym[3], + score: 1.0, + }); + } + } + if (symbolMatches.length === 0) return ''; // Step 3: Batch-fetch callers/callees/processes/cohesion for top matches diff --git a/gitnexus/test/integration/augmentation.test.ts b/gitnexus/test/integration/augmentation.test.ts index aed09d61f..60c4170fd 100644 --- a/gitnexus/test/integration/augmentation.test.ts +++ b/gitnexus/test/integration/augmentation.test.ts @@ -57,6 +57,7 @@ vi.mock('../../src/storage/repo-manager.js', () => ({ })); let augment: (pattern: string, cwd?: string) => Promise; +let augmentNoFts: (pattern: string, cwd?: string) => Promise; withTestLbugDB( 'augment', @@ -106,6 +107,28 @@ withTestLbugDB( const result = await augment('日本語テスト', handle.dbPath); expect(typeof result).toBe('string'); }); + + // ─── Negative-safety: fallback must stay gated on !ftsAvailable ─── + // + // When FTS is available but happens to return zero BM25 hits, the + // CONTAINS fallback must NOT fire — preserving the original early-return + // semantics.

Add createResolverParityIt wrapper to java.test.ts for parity testing. All 172 existing Java tests pass. Java is NOT added to MIGRATED_LANGUAGES — the resolver sits idle until the migration flag is flipped.

Co-Authored-By: Claude Opus 4.7 (1M context) * feat(communities): seed Leiden RNG for deterministic community detection The vendored Leiden algorithm defaults to Math.random for tie-breaking and randomized walks, which produces non-deterministic community assignments and modularity values across runs on the same graph. Pass a seeded mulberry32 RNG (LEIDEN_SEED=0xC0DE) so: - The same graph always produces the same partition - Modularity values are reproducible - Equivalence tests for incremental indexing can compare community assignments byte-for-byte This is foundational for the upcoming incremental-indexing feature (see docs/superpowers/specs/2026-05-10-incremental-indexing-design.md) where the correctness contract is incremental output ≡ full rebuild output. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(incremental): change-detection, surface signatures, closure expansion Three new modules supporting the incremental-indexing pipeline: * core/incremental/git-diff.ts — getChangedFilesSinceCommit() unions 'git diff lastCommit HEAD' (committed) with 'git status --porcelain' (dirty tree). Renames flattened to delete(orig) + add(new). Throws LastCommitMissingError when lastCommit is gone (caller falls back to full rebuild). * core/incremental/surface.ts — extractSurfaceSignature() produces a stable hash of a file's publicly-visible symbols (functions, classes, methods, interfaces, types, heritage). Body-only edits → same hash. Signature/heritage changes → different hash. Drives the closure scoping optimization. * core/incremental/closure.ts — computeImporterClosure() iterative fixpoint: parse each closure file, extract surface, query DB importers, expand. Uses a parseCache so each file is parsed once. Generic over TParseResult so closure logic is decoupled from the pipeline's parse representation. 32 unit tests across the three modules. Tests cover edge cases: clean tree, dirty-only, mixed, renames, deletes, multi-hop cascade, cycle termination, surface invariance, etc. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(lbug): loadGraphFromLbug, queryImporters, deleteAllCommunitiesAndProcesses Three new primitives in lbug-adapter.ts to support incremental indexing: * loadGraphFromLbug(graph, unchangedFilePaths) — streams all nodes for files in the set across every hydratable node table (excludes Community/Process — graph-wide, regenerated downstream). Then loads edges where both endpoints belong to loaded nodes, excluding MEMBER_OF / STEP_IN_PROCESS edges (also graph-wide). FilePaths chunked at 200 per query to keep statement size bounded on huge repos. Endpoint-level join filters by source-side filePath in the query, target-side checked JS-side via the loadedNodeIds set. * queryImporters(targetFilePath) — returns DISTINCT a.filePath where a -[IMPORTS]-> b and b.filePath = target. Powers closure expansion: when a changed file's surface signature changes, all its importers must be re-parsed. * deleteAllCommunitiesAndProcesses() — drops Community/Process nodes (and their edges via DETACH DELETE) at the start of each incremental run so the communities/processes phases regenerate them from the fully-merged graph. Required for the 'Leiden runs on full graph' correctness invariant. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(pipeline): hydrate phase + parse-filter for incremental indexing Wires the incremental-indexing infrastructure into the phase-based pipeline. Three coordinated changes: * New hydratePhase (deps: structure) — loads node/edge state for files OUTSIDE ctx.options.filesToParse from the existing LadybugDB index. Runs before parse so the parse phase can produce a partial graph while downstream phases (mro, communities, processes) still see the full graph. No-op in full-rebuild mode (filesToParse unset). * PipelineOptions.filesToParse: optional ReadonlySet. When set, parse phase filters scanned files to this set; hydrate fills the complement. Set by runFullAnalysis when it detects an eligible incremental run; never set by callers directly. * gitnexus-shared PipelinePhase enum: 'hydrate' added so progress callbacks can report the new phase distinctly from 'structure'. Phase order: scan → structure → hydrate → markdown,cobol → parse → routes,tools,orm → crossFile → scopeResolution → mro → communities → processes. Communities (Leiden) still runs on the full graph, satisfying the correctness invariant. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(analyze): incremental orchestrator branch + meta schema Wires incremental indexing into runFullAnalysis. Highlights: * RepoMeta schema extended: schemaVersion, surfaceSignatures, and incrementalInProgress fields. INCREMENTAL_SCHEMA_VERSION = 1. * core/incremental/file-hash.ts — v1 surface signature: SHA-256 of file content. v2 will switch to a true surface-only signature (defined in surface.ts) so body-only edits don't expand the closure. The plumbing is signature-agnostic so the swap is local. * core/incremental/orchestrator.ts — eligibility check, closure computation (uses file-hash as the surface signal), dirty-flag management, subgraph extraction, signature merge. * run-analyze.ts adds: - hasDirtyTree() check on the existing 'lastCommit==HEAD' early-exit so an uncommitted edit triggers re-index (was a coarse equality check before). - incremental branch: try incremental first; fall through to full rebuild on any setup failure or eligibility miss. - runIncrementalBranch() — opens existing DB, deletes closure-file rows + Community/Process, runs pipeline with filesToParse, writes only the changed-subgraph back, refreshes FTS, updates meta with new surfaceSignatures and clears the dirty flag. - Full-rebuild path now populates surfaceSignatures + schemaVersion in meta.json so the next run is eligible for incremental. Crash recovery: incrementalInProgress is set BEFORE any DB mutation and cleared on success by overwriting meta.json. A crash anywhere in between leaves the flag set, and the next analyze run forces a full rebuild (cheapest path back to a known-good index). v1 limitation documented: body-only edits trigger 1-hop closure expansion (content-hash signal). True surface-only optimization is deferred to v2 — see design doc for the integration path. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): drop invalid --no-renames=false from git diff The flag --no-renames=false isn't valid git syntax (it's parsed as a file path). Git's default rename detection is on; removing the flag keeps that behavior. Caught while running an end-to-end smoke test against a small fixture repo: incremental setup failed with 'Command failed: git diff --name-status -z --no-renames=false ...'. After the fix, the incremental path runs cleanly: closure is computed, hydrate phase loads unchanged-file state from DB, parse phase only re-parses files in closure, and the writeback updates only changed nodes/edges. Co-Authored-By: Claude Opus 4.7 (1M context) * Revert v1 incremental indexing (5 commits) Reverts the v1 design that parsed only closure files into a fresh graph and tried to hydrate the rest from DB. Real-repo equivalence test failed: cross-file resolution operates on partial parse data (closure files only), so CALLS edges that resolve through unchanged files silently fall off. Diff against full rebuild on the same edited state: -50 nodes, -425 edges, -5 communities, -48 processes. Architecture pivot: switch to PR #533-style content-addressed parse cache. Pipeline parses every file (cache-served when possible), giving cross-file resolution full data, with DB writeback then restricted to changed-file rows. Reverts: d4b9de47 fix(incremental): drop invalid --no-renames=false f35f7634 feat(analyze): incremental orchestrator branch + meta schema bc039686 feat(pipeline): hydrate phase + parse-filter 98bb893d feat(lbug): loadGraphFromLbug, queryImporters, ... aa8d7ae3 feat(incremental): change-detection, surface signatures, closure Kept: d9e340b0 feat(communities): seed Leiden RNG (foundational) 8235ca36 docs: incremental indexing design spec (will be revised) Co-Authored-By: Claude Opus 4.7 (1M context) * feat(analyze): incremental DB writeback (Option B) Equivalence-preserving incremental analyze. The pipeline still parses every file (correctness invariant: cross-file resolution / scope resolution / MRO / community detection all need full graph data); the saving comes from selectively replacing only changed-file rows in LadybugDB instead of wiping and reloading the whole graph. How it works: * On every analyze, we hash all source files (SHA-256 of content) and store the map in meta.json.fileHashes alongside schemaVersion. * The next run loads the prior map and diffs: - changed: content hash differs → file's DB rows replaced. - added: not in prior map → file's DB rows inserted. - deleted: in prior map but not on disk → file's DB rows dropped. * If the diff is non-empty AND no --force / no schema mismatch / no dirty flag, take the incremental path: - Set incrementalInProgress dirty flag (BEFORE any DB mutation). - Open existing DB (no wipe). - deleteNodesForFile() for each changed/added/deleted file. - deleteAllCommunitiesAndProcesses() — Leiden regenerates these. - extractChangedSubgraph() from the in-memory ctx.graph: nodes whose filePath is in the writable set + Community + Process + edges with at least one endpoint in the writable set (edges entirely between hydrated unchanged nodes are skipped — already in DB). - loadGraphToLbug() on the subgraph. Unchanged-file rows in DB untouched. - Recreate FTS indexes. - Update meta with new fileHashes; clear dirty flag. * Otherwise full-rebuild path runs as before. Crash recovery: incrementalInProgress is the dirty flag. Set before destructive ops; cleared on success. Set on next-run startup → forces full rebuild (cheapest path back to known-good). Other changes: * Dirty-tree gate on the existing 'lastCommit==HEAD' early-return: uncommitted edits no longer slip through as 'already up to date'. * deleteAllCommunitiesAndProcesses helper in lbug-adapter. * Skip the embedding cache+restore cycle when willTryIncremental is true — embeddings stay in DB; re-inserting them would PK-conflict. End-to-end equivalence verified on this repo (993 files, 24K nodes): incremental run produces byte-identical {nodes, edges, clusters, flows} to a full rebuild from the same edited state. Speedup is currently modest (~5% on this repo) because the parse phase still runs in full. Parse-cache integration is a separate follow-up that composes cleanly on top of this work. See docs/superpowers/specs/2026-05-10-incremental-indexing-design.md. Co-Authored-By: Claude Opus 4.7 (1M context) * feat(analyze): chunk-level parse cache for full incremental speedup Composes with the incremental DB writeback (commit 27f3b49d) to deliver the major-speedup half of incremental indexing. Previously, the parse phase ran in full on every analyze; the speedup came purely from selective DB rewriting. With this commit the parse phase also reuses prior tree-sitter output for chunks whose contents haven't changed. How it works: * Cache layer (gitnexus/src/storage/parse-cache.ts): - File: /.gitnexus/parse-cache.json. Versioned, atomic write. - Key: chunk content hash = sha256(sorted(filePath:fileContentHash for each file in chunk)). - Value: ParseWorkerResult[] (raw worker output for the chunk, pre-merge). - Granularity: per chunk (~20MB byte-budget). A change to one file invalidates only its chunk — typically 1 of ~50 on a 1000-file repo (~98% cache hit ratio on a small edit). * Worker contract (gitnexus/src/core/ingestion/parsing-processor.ts): - Extracted the chunk-result merge loop into a public mergeChunkResults() so the same logic applies to live worker output AND replayed cache entries. - processParsingWithWorkers / processParsing accept an optional outRawResults out-parameter that captures worker output before merging — used by parse-impl to populate the cache after a miss. * Parse phase wiring (parse-impl.ts): - For each chunk, compute its content hash (after reading file contents). Cache hit → mergeChunkResults() on cached results, skip the worker dispatch entirely. Cache miss → run workers normally, capture raw results, store under the chunk hash. - Cache mutations happen in-place on the ParseCache passed via PipelineOptions.parseCache. * Lifecycle (run-analyze.ts): - loadParseCache() before pipeline runs. - Cache passed via runPipelineFromRepo's PipelineOptions. - saveParseCache() after the pipeline + DB writeback succeed. Equivalence verified on this repo (993 files, 24K nodes): Cold (no cache, full work): 141.1s Warm cache + 1-file edit, incremental: 63.6s ← 55% speedup Warm cache + 1-file edit, --force: 71.6s ← 49% speedup All three runs produce byte-identical {nodes, edges, clusters, flows}. The cache survives --force (content-addressed = always correct), so even forced rebuilds get the parse-skip benefit. Why chunk-level rather than per-file: workers process sub-batches and emit aggregated ParseWorkerResults. Per-file granularity would require restructuring the worker contract; chunk-level captures most of the practical speedup with no worker-side changes. Co-Authored-By: Claude Opus 4.7 (1M context) * perf(parse-impl): smaller default chunk budget (20MB→2MB) for cache granularity The parse cache is keyed at chunk granularity. With the previous 20MB budget, a typical mid-size repo (e.g. this worktree at 9MB total parseable source) fits in a single chunk — meaning ANY file change invalidates the whole chunk and re-parses every file. 2MB default produces ~5x more chunks on the same input, so a one-file edit invalidates ~1/N of cached chunks instead of the whole thing. Cold-run overhead from more chunks is <5% (one extra serialization pass per chunk). Override via GITNEXUS_CHUNK_BYTE_BUDGET env var for benchmarking. Measured on this repo (~9MB / 887 parseable files): Cold (no cache): 143s Warm cache, no source changes: 2s (early-return) Warm cache + 1-file edit: 81s (~43% off cold) Speedup is bounded by the scopeResolution phase (~58s flat regardless of parse cache) and by GitNexus's own auto-writes during analyze (AGENTS.md / .claude/skills/ etc. mutate between runs and invalidate chunks containing them). Both are addressable in follow-ups. Co-Authored-By: Claude Opus 4.7 (1M context) * perf(scope-resolution): reuse worker-produced ParsedFile + stabilize chunk order Two compounding optimizations that drop warm-cache analyze from ~134s to ~38s on a 1000-file repo (72% faster), and cold rebuild from ~143s to ~86s (40% faster) by short-circuiting work that was previously re-done. 1. SCOPE-RESOLUTION: REUSE WORKER PARSEDFILE Previously, the scope-resolution phase re-parsed every file with tree-sitter on the main thread (~58s on a 1000-file repo) because worker-produced tree-sitter Trees can't cross the worker MessageChannel. But the worker ALSO produces a artifact via , which structured-clones fine — and it's exactly what scope-resolution would re-derive. Threading those ParsedFiles through the parse phase () into ( map) lets scope- resolution skip its extract loop on a per-file basis. The fast path is bounded only by per file (cheap graph mutation). On this repo: scopeResolution went from 58s → 5s. 2. MAP-PRESERVING PARSE-CACHE SERIALIZATION is a which JSON.stringify collapses to . The first attempt at threading parsedFiles through the parse cache crashed at runtime with "importerModule.typeBindings is not iterable" because cached entries came back as plain objects. Added a JSON replacer/reviver pair in parse-cache.ts that round-trips Map and Set instances through tagged plain objects (). Symmetric: save uses replacer, load uses reviver. 3. STABLE CHUNK ORDERING The byte-budget chunker walked files in filesystem-scan order, which on Windows isn't guaranteed to be stable across runs. Even with identical source content, two scans could place files in different chunks, shifting chunk hashes and causing 100% parse-cache misses. Added a deterministic alphabetical sort on before chunking. Chunk membership is now stable across runs, so a single-file edit invalidates exactly one chunk, not all of them. Measured on this repo (993 files, 24K nodes): Cold rebuild: 86s (was 143s) Warm cache, no source changes: 3s (early-return) Warm cache + 1-file edit: 38s (was 134s) Co-Authored-By: Claude Opus 4.7 (1M context) * docs(incremental): update spec + AGENTS.md + GUARDRAILS.md for shipped design - Rewrite docs/superpowers/specs/2026-05-10-incremental-indexing-design.md to describe the architecture that actually shipped (parse cache + incremental DB writeback + scope-resolution short-circuit), with the v1 hydrate-phase post-mortem preserved as historical context. - AGENTS.md "Keeping the Index Fresh" section: note that incremental is the new default and --force is the explicit opt-out; mention the parse-cache file location and that it's safe to delete. - GUARDRAILS.md Signs: add an "Index seems corrupt or incremental is misbehaving" entry pointing users to --force as the manual escape hatch (the dirty flag handles automatic recovery). Co-Authored-By: Claude Opus 4.7 (1M context) * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(incremental): bugbot review + CI test failures Bugbot (PR #1479): - Medium: pruneCache was exported but never called -> cache grew unbounded. Wire pruneCache into run-analyze before saveParseCache, using a transient usedKeys Set on ParseCache that the parse phase populates as it processes chunks. - Low: willTryIncremental (pre-pipeline) and isIncremental (post-pipeline) could desync, silently dropping embeddings on mispredicted runs. Removed the prediction; the embedding cache now loads unconditionally when shouldLoadCache is true. The re-insert step gates on the actual isIncremental value to avoid PK-conflicts when the incremental-writeback path keeps DB rows. CI test failures: - cli-e2e #1169 + run-analyze.test.ts #1233: my dirty-tree gate on the lastCommit==HEAD early-return saw GitNexus's own auto-generated outputs (.claude/, .cursor/, AGENTS.md, CLAUDE.md) as dirty, perpetually defeating the up-to-date fast path. Extended the pathspec exclusion to cover all auto-gen outputs, not just .gitnexus/. - ruby field-type disambig: my chunk-stability sort exposed a pre-existing order-dependency in Ruby cross-file resolution (`user.address.save -> Address#save` only resolves correctly when user.rb parses before address.rb in some configurations). Removed the sort. Filesystem ordering is stable enough in practice that the parse cache still hits the common case; the pre-existing fragility is left for a separate fix. - pipeline-graph-golden: regenerated. Seeded Leiden RNG produces a partition different from the previous Math.random snapshot. - staleness `parallel calls` was a CI timing flake; passes locally. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): re-insert cached embeddings on incremental path Bugbot re-review caught: deleteNodesForFile cascades to the CodeEmbedding table (DELETE WHERE e.nodeId STARTS WITH ...), so changed-file embedding rows are wiped along with their nodes. The previous fix gated re-insert on `!isIncremental`, which silently dropped those embeddings — a regression versus the full-rebuild path's "preserve embeddings by default" guarantee. Remove the `!isIncremental` gate. The per-batch try/catch already handles the unchanged-file PK-conflict case ("some may fail if node was removed, that's fine") with the same semantics, so re-inserting the full cached set on incremental works: - changed-file rows: deleted, then re-inserted from cache (preserved) - unchanged-file rows: still in DB, re-insert PK-conflicts and is silently ignored (existing rows are correct) Cost: re-inserting ~24K embeddings on incremental when only a few files changed — most are no-op conflicts. Bounded by batch size of 200; ~3-5s overhead. Worth it for correctness. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): address Claude+Bugbot review findings + remove design doc Addresses CHANGES_REQUESTED review on PR #1479: 1. Remove docs/superpowers/specs/2026-05-10-incremental-indexing-design.md per maintainer request. 2. BLOCKER (Claude Finding 1, Bugbot Round 3): Stale cross-file edges between unchanged files. extractChangedSubgraph excluded edges where both endpoints were unchanged-file nodes — when a barrel/re-export file changes, cross-file resolution may update CALLS edges between two unchanged files that would then be silently lost. Fix: 1-hop importer-closure expansion of the writable set in run-analyze.ts. Before deleting/rewriting rows, query DB for importers of every changed/deleted file and add them to the writable set. Their nodes get deleted+rewritten too, so cross-file's refined edges land in the DB. Re-added queryImporters to lbug-adapter.ts. 3. BLOCKER (Claude Finding 3): Parse cache key omitted parser version. After a GitNexus upgrade, the cache silently replays pre-upgrade ParseWorkerResults against the new schema → wrong CALLS/IMPORTS/ scope edges with no visible signal. Fix: PARSE_CACHE_VERSION now embeds the gitnexus npm package version (read at module load via createRequire on package.json). Format: `${SCHEMA_BUMP}+${PKG_VERSION}` e.g. "1+1.6.4". Any release that bumps package.json automatically invalidates the on-disk cache. Mismatched versions fall through to an empty cache (next save overwrites with the new version baked in). 4. BLOCKER (Claude Finding 2): No automated tests for incremental behavior. Added 28 unit tests across 3 files: - incremental-file-hash.test.ts (10 tests) diffFileHashes classification, computeFileHash determinism, computeFileHashes batch / missing-file tolerance, sorted output. - incremental-parse-cache.test.ts (12 tests) computeChunkHash stability and order-independence, version prefix format, pruneCache, load/save round-trip on empty / missing / corrupt / version-mismatched files, AND a Map/Set round-trip test that pins the JSON replacer/reviver behaviour (without it, ParsedFile.scopes[*].typeBindings collapses to {} and downstream `.get()` / iteration throws). - incremental-subgraph-extract.test.ts (6 tests) writable-set node inclusion, Community/Process always kept, edge inclusion when at least one endpoint is writable, MEMBER_OF edges via graph-wide endpoints, empty subgraph case. 5. Medium (Claude Finding 6): AGENTS.md "Keeping the Index Fresh" said "only changed files are re-parsed." Imprecise — the pipeline parses every file every run; the cache skips tree-sitter for chunks whose contents haven't changed. Reworded to match the design doc. Test plan still expects: [x] Typecheck clean [x] All 28 new unit tests pass [x] All previously-failing tests still pass on the rebased branch [x] Equivalence verified locally (incremental ≡ --force, byte-identical stats on this repo) Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): round 3 review feedback — bounded BFS, atomic meta, integration test, docs Addresses remaining findings on PR #1479 from Claude's re-review of commit ad7bd31 + verifies the outstanding Bugbot HIGH severity. 1. F1 — Transitive importer expansion (Claude, was Medium-but-noted). Previous 1-hop importer expansion missed barrel re-export chains (A imports C, C re-exports B; when B changes, only C was pulled in — A was left with potentially-stale CALLS edges to refined targets). Replaced the single pass with a bounded BFS over the IMPORTS graph (depth ≤ 4). Catches nested barrel pyramids without ballooning into a near-full rebuild on monorepos with deep re-export trees. `--force` remains the escape hatch documented in GUARDRAILS.md for cases that exceed the bound. 2. F2 — Integration test for incremental orchestration (Claude, BLOCKER, DoD §2.7). The unit tests added in ad7bd31 covered `diffFileHashes`, `extractChangedSubgraph`, `computeChunkHash`, `pruneCache`, and the Map/Set JSON round-trip — but none of them exercised the real `runFullAnalysis` orchestration. Added gitnexus/test/unit/ incremental-orchestration.test.ts with four end-to-end tests against a real git-initialized fixture repo + real LadybugDB: a. First run populates fileHashes + schemaVersion and clears incrementalInProgress on success. b. Second run on unchanged state takes the alreadyUpToDate fast path (early-return). c. Second run after a source edit takes the incremental path (not full rebuild) and rotates fileHashes for the touched file while keeping the dirty flag cleared. d. A pre-set incrementalInProgress flag forces a full rebuild that clears it (crash-recovery wire). These would catch any regression that wires `isIncremental` from a pre-pipeline prediction (the Bugbot finding from commit 5eb0597) or accidentally re-gates the embedding re-insert on `!isIncremental` (the Bugbot finding from commit 60c10f1). 3. F3 — GUARDRAILS.md docs accuracy (Claude, Low). Line 33 still said "only changed files are re-parsed" — AGENTS.md was already corrected in ad7bd31 but GUARDRAILS.md was missed. Reworded to match. 4. F5 — Atomic saveMeta (Claude, Medium; vvladescu-tb fork). The dirty flag (`incrementalInProgress`) travels through meta.json. A crash mid-write would leave a corrupt meta.json that `loadMeta` would silently treat as "no prior index", losing the flag and skipping recovery. Switched to tmp-file + rename matching saveParseCache. 5. Bugbot's "Subgraph edges reference nodes absent from subgraph" (HIGH severity). Verified as FALSE POSITIVE: `getNodeLabel` in lbug-adapter.ts derives labels from the node-ID string (parses the table prefix), not from the in-memory graph. The CSV generator writes (src_id, dst_id, type) rows without consulting node objects; `splitRelCsvByLabelPair` routes by ID-derived label; `COPY ... (from=X, to=Y)` resolves both endpoints against the live LadybugDB where unchanged-file nodes still exist. No fix needed. All 213 tests pass locally (including the 4 new integration tests and the previously-failing CI tests). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(incremental): address Bugbot round-4 findings (added-file shadow seed + dedupe) Bugbot review on commit e23e4400 surfaced two new findings against the incremental writeback in run-analyze.ts: HIGH — Incremental BFS misses importers of newly added files. queryImporters() reads the pre-pipeline DB. For a NEWLY ADDED file there are no IMPORTS rows pointing to it yet, so unchanged files whose pre-existing import statements now resolve to the newcomer keep stale CALLS edges pointing at the OLD resolution target. LOW — Deleted files double-counted in filesToDelete. hashDiff.deleted entries can reappear in writableFiles via the BFS expansion (queryImporters can return a now-deleted path), so deleteNodesForFile() ran twice for the same file. Fixes: - Add gitnexus/src/core/incremental/shadow-candidates.ts: derive the pre-existing file paths whose JS/TS module-resolution claim an added file can steal. Pattern catalogue: same-basename/ different-extension, bare-file-beats-directory-index, and directory-index-beats-bare-file. Emit both POSIX and Windows separators because the prior fileHashes map may have been written from either OS. - In run-analyze.ts, seed the BFS frontier with shadow candidates that exist in the prior meta.fileHashes. Their importers — found via queryImporters — get pulled into the writable set so their CALLS edges re-resolve against the new file. - Dedupe filesToDelete via Set to avoid the double-call. Tests: gitnexus/test/unit/incremental-shadow-candidates.test.ts — 8 cases covering each shadow pattern, separator handling, .d.ts as a single extension token, deduplication, and the no-self-shadow invariant. All 40 incremental tests (file-hash, parse-cache, subgraph-extract, shadow-candidates, orchestration) pass locally. Note on the third Bugbot finding ("Subgraph edges reference nodes absent from subgraph"): re-anchored from a prior review pass — the code at subgraph-extract.ts:48 is unchanged. Already verified as a false positive: getNodeLabel parses labels from ID strings, CSV write is by ID, and COPY resolves against the live DB. * chore(autofix): apply prettier + eslint fixes via /autofix command * test(incremental): exact-equality stats invariant + analyze ≡ analyze --force Addresses the only remaining Claude production-readiness review finding on PR #1479 (Low-Medium, test-quality only — Claude itself said it does NOT block merge, but the central PR claim "incremental ≡ full rebuild" deserves explicit CI coverage rather than implicit trust). Changes to gitnexus/test/unit/incremental-orchestration.test.ts: 1) Tighten the existing "comment-only edit takes incremental path" test. - Replace toBeGreaterThan(0) bounds assertions on stats.files and stats.nodes with exact toBe(firstMeta) per-field equality across files / nodes / edges / communities / processes. DoD §2.7 calls out bounds-only assertions as masking regressions that drop half the graph; this swap closes that gap. - Rationale: a comment-only edit must change the file content hash (driving the incremental path) without changing any graph data. Therefore every stat MUST be identical to the first run. Anything else is a regression. 2) New test: incremental output is byte-equivalent to a full rebuild. - Run analyze → comment-only edit → analyze (incremental writeback) → analyze --force (full rebuild from same on-disk state). - Assert files / nodes / edges / communities / processes are exactly equal across the incremental and the --force passes. - This is the PR's central correctness contract, now proven by a test that exercises the real runtime path end-to-end against a real on-disk LadybugDB. All 5 orchestration tests pass locally (52s), including the new equivalence test — every stat field matches exactly between incremental and --force on the mini-repo fixture. tsc --noEmit clean. * fix(incremental): F1 cross-file edge consistency + F4 stable chunk sort + unit coverage (#1511) Patch addressing two of the still-open changes-requested findings on PR #1479, rebased onto the current feat/incremental-indexing head. F3 (parser fingerprint in the cache key), F5 (atomic saveMeta), and F6 (AGENTS.md phrasing) were already handled on the branch, so the corresponding parts of the original patch were dropped as redundant. F1 (Blocker) — Cross-file edges between unchanged files Adds `computeEffectiveWriteSet(graph, toWriteSet)` to subgraph-extract.ts: a single pass over the new graph's edges that pulls the unchanged-side file of every writable-boundary-crossing edge into the write set. run-analyze composes it ON TOP of the existing importer-BFS expansion and feeds the combined set to BOTH `deleteNodesForFile` and `extractChangedSubgraph`, so the delete cascade and the writeback subgraph cover identical files (asymmetry would leave stale rows or PK-conflict at COPY time). The BFS reads IMPORTS from the pre-pipeline DB (catches files that *stopped* importing a changed file); the edge walk reads the new graph (catches refined CALLS edges the pre-run DB couldn't predict, e.g. a barrel re-export shifting a symbol from B to D). `extractChangedSubgraph` stays a pure filter — all expansion is the orchestrator's job. F4 (Medium) — Restore alphabetical chunk sort `parseableScanned` is sorted before chunking. Filesystem-scan order isn't stable enough across runs/platforms (notably macOS APFS) to keep chunk hashes consistent, so the parse cache thrashes without it. The pre-existing Ruby cross-file resolution order-dependency the old comment cited is independent — the sort surfaces it but doesn't cause it; tracked separately rather than leaving the cache cold. Tests — incremental-subgraph-extract.test.ts Locks the F1 invariants: `extractChangedSubgraph` is a pure filter (includes only the set it's given, plus graph-wide nodes; edges fire on one writable endpoint), and `computeEffectiveWriteSet` covers the barrel-re-export scenario, the symmetric edge-into- changed-file case, the no-boundary-crossed no-op, graph-wide-node edges, and input-immutability. Supersedes the prior extractChangedSubgraph-only test file on the branch.

That left the sequential and worker paths emitting non-identical Property nodes/symbols for the same source — silently breaking the `incremental ≡ --force` invariant the moment a repo crosses the worker threshold between runs. Two concrete divergences are closed here: * Node id: worker keys Property as `${file}:${className}.${propName}` (qualified). Pre-pass was using `${file}:${propName}` (unqualified). Same source produced different graph ids depending on which path ran. * Field metadata: worker enriches each routed property with `provider.fieldExtractor` + `getFieldInfo`, falling back to `routedFieldInfo.type` for `declaredType` when the routing payload lacks one (e.g. types discovered from `@address = Address.new` ctor assignments rather than YARD `@return [Type]`), and propagates `visibility` / `isStatic` / `isReadonly`. Pre-pass did none of this, so on the sequential path `resolveFieldAccessType` failed to walk chains where the type only came from the FieldExtractor. The pre-pass now mirrors parse-worker.ts:1803-1898 verbatim, with one deliberate difference: the FieldInfo cache is scoped to a single `processCalls` invocation rather than module-level (the worker process is short-lived; the main thread is not, and a module-level cache would leak state between analyze runs). Also drops the now-stale "Defer resolution: Ruby attr_accessor properties are registered during this same loop" comment on `pendingWrites.push` — the rationale is no longer accurate after Copilot's pre-pass, but the deferral is still needed so write-access tracking sees inference that completes during the main loop. Comment updated to reflect that. Verification: * `tsc --noEmit`: 0 errors * test/unit (call-processor, call-routing, field-extraction, ruby-self-call): 224 passing * test/integration (ruby, ruby-sequential-mixin, pipeline-graph-golden): 137 passing Co-Authored-By: Claude Opus 4.7 (1M context) * fix(call-processor): key fieldInfoCache by filePath:startIndex, not raw byte offset Claude's review of 255bdf6 caught a real collision in the FieldInfoCache I added: keying by `classNode.startIndex` alone is a per-file byte offset, so two files that both begin with a class at byte 0 — extremely common in Ruby / Python, where files frequently open with `class Foo`, `module Foo` — collide on the same cache entry. The second file's `getFieldInfo` then returns the first file's FieldInfo map, producing wrong `declaredType` / `visibility` / `isReadonly` on its properties. Same shape as the bug that already exists in parse-worker.ts:377 (also keyed by `classNode.startIndex` in a module-level map, persistent across files processed by the same worker). Fixing the symmetric pre-existing leak in parse-worker.ts is a separate, scoped follow-up — left out of this commit to keep the fix minimal and reviewable.

The import resolver now strips JS-family extensions (.js/.jsx/.mjs/.cjs) and retries with TS equivalents (.ts/.tsx/.mts/.cts) when the literal .js file does not exist. This fallback only applies to TypeScript/JavaScript languages. Also adds .mts/.cts to the EXTENSIONS list for completeness. Fixes #1503 * fix: address review findings — normalization, edge-case tests, integration test - Fix makeCtx to use production normalization (.replace backslash) instead of .toLowerCase() (Finding 3) - Add tests for .mjs/.cjs with competing .ts/.mts siblings (Finding 1) - Add tests for ./dir.js → dir/index.ts boundary (Finding 2) - Add integration test verifying full pipeline CALLS edges for ESM .js imports (Finding 4) - Document path alias .js limitation as known follow-up (Finding 5) * chore(autofix): apply prettier + eslint fixes via /autofix command * chore: retrigger CI after bot-only tip commit Co-authored-by: Cursor --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Gergo Magyar Co-authored-by: Cursor --- .../ingestion/import-resolvers/standard.ts | 32 +++- .../core/ingestion/import-resolvers/utils.ts | 4 + .../typescript-esm-js-extension.test.ts | 62 +++++++ .../unit/esm-extension-resolution.test.ts | 153 ++++++++++++++++++ 4 files changed, 250 insertions(+), 1 deletion(-) create mode 100644 gitnexus/test/integration/resolvers/typescript-esm-js-extension.test.ts create mode 100644 gitnexus/test/unit/esm-extension-resolution.test.ts diff --git a/gitnexus/src/core/ingestion/import-resolvers/standard.ts b/gitnexus/src/core/ingestion/import-resolvers/standard.ts index f8aae9625..47e2dabb2 100644 --- a/gitnexus/src/core/ingestion/import-resolvers/standard.ts +++ b/gitnexus/src/core/ingestion/import-resolvers/standard.ts @@ -128,7 +128,21 @@ export const resolveImportPath = ( if (importPath.startsWith('.')) { const resolved = tryResolveWithExtensions(basePath, allFiles); - return cache(resolved); + if (resolved) return cache(resolved); + + // TypeScript ESM: imports use .js/.jsx/.mjs/.cjs but source files are + // .ts/.tsx/.mts/.cts.

Under heavy parallel search load (issue #1486: 180+ piled-up processes, load avg > 100), these accumulated faster than they completed because nothing capped concurrent in-flight augments. Add a lockfile-based concurrency guard under `<.gitnexus>/.hook-locks/`: each running hook claims a `.lock`, the guard counts live PIDs and prunes stale entries (>30s mtime or pid no longer alive), and bails silently when MAX_INFLIGHT (3) is reached. Augment is best-effort enrichment — missing a few fires under burst load is preferable to melting the system. Applied to all three hook variants that spawn augment: - gitnexus/hooks/claude/gitnexus-hook.cjs (npm-installed Claude hook) - gitnexus-claude-plugin/hooks/gitnexus-hook.js (plugin Claude hook) - gitnexus-cursor-integration/hooks/gitnexus-hook.cjs (Cursor hook) Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): make augment concurrency cap a hard cap via atomic slot files Address Claude's review of #1510. The original count-then-claim guard had a TOCTOU window: N hooks could each read `active < MAX_INFLIGHT` between readdirSync and the per-pid `wx` write and all proceed, briefly exceeding the cap. The PR title's "cap" language overstated this. Replace with fixed-name `slot-0.lock` ... `slot-N.lock` under `.hook-locks/`. `O_CREAT|O_EXCL` on a fixed path is OS-atomic — exactly one process wins each slot, so the cap is hard regardless of burst arrival timing. Each slot file contains the owning PID so stale-takeover still works when a hook crashes without releasing. PID liveness is checked before age (Claude's Finding 3): a slow-but-alive hook is never wrongly evicted. The 30s age window only kicks in to defend against PID reuse on a long-abandoned slot, well above the 7s augment timeout so a healthy run never hits it. Also adds the missing concurrency-guard tests to cursor-hook.test.ts (Claude's Finding 2): source-level wiring + dead-PID reclaim + 3-slots-full bail. Previously only the CJS and Plugin variants had test coverage for the guard; the Cursor variant was validated only by code inspection. Tests: 5726 passing, +9 from baseline (1 hard-cap burst test + 4 source regressions in hooks.test.ts; 3 source + 2 integration in cursor-hook.test.ts). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): inspect slot mtime + content via single fd (codeql TOCTOU) CodeQL flagged the stale-takeover path in acquireHookSlot as a potential filesystem race (js/file-system-race): statSync(slotPath) followed by readFileSync(slotPath) gives a TOCTOU window where the file could be swapped between the metadata check and the content read. Replace the two separate path-based calls with a single openSync + fstatSync + readSync + closeSync sequence. Both mtime and owner PID now come from the same file descriptor, so the operations are atomic on one inode. No behavioral change beyond closing the race. Applied to all three hook variants (CJS, Plugin, Cursor). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): distinguish EPERM from ESRCH in PID liveness check Cursor Bugbot caught a contradiction with the stated design: the bare `catch` after `process.kill(owner, 0)` was treating EPERM (process exists but owned by another user) the same as ESRCH (process gone), which would evict a live slot whenever the lock dir straddled user boundaries. Inspect the error code: ESRCH → dead, evict; EPERM → still alive, keep the slot; anything else → assume alive (be conservative under unexpected failure rather than over-evict). Applied to all three hook variants. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(hooks): fail closed when lock dir cannot be created Previously the mkdirSync catch in acquireHookSlot returned `() => {}` (a truthy no-op). The caller checks `if (!release) return;` to skip augment when the guard can't be established — but a truthy no-op slipped through that check and let augment spawn unguarded. On a cross-user shared `.gitnexus/` or read-only filesystem, N concurrent hooks would each take that branch and reintroduce the #1486 fan-out the guard exists to prevent. Return `null` instead so the caller's `if (!release) return;` skips augment cleanly. Augment is best-effort enrichment — skipping it when the guard fails is strictly safer than running unguarded. Also clarify the stale-slot comment: PID-liveness wins for slots younger than HOOK_LOCK_STALE_MS, but age is the final arbiter beyond 30s (PID-reuse defense). The previous wording said "PID-liveness wins over age" without qualifying it, which contradicted the >30s branch. Add source-level regression tests in hooks.test.ts and cursor-hook.test.ts asserting acquireHookSlot returns null (not () => {}) on lock-dir failure. Note in the Cursor test file that the 10-spawner burst test is not duplicated because the algorithm is byte-for-byte identical to the CJS hook and already covered there.

Lets users maintain lean custom context without it being overwritten on every reindex. Co-Authored-By: Claude Opus 4.6 (1M context) * feat: improve gitnexus:keep marker to reliably preserve custom sections The `` marker inside a GitNexus block tells `analyze` to only update the stats line (node/edge/flow counts) while preserving the user's custom layout. This lets teams trim the verbose default template to a lean format without having it overwritten on every reindex. Changes: - Broaden stats-line regex to match both "Indexed as" and "indexed by GitNexus as" formats - Improve stats extraction from generated content (prefer structured match over greedy parentheses) - If keep marker is present but no stats line found, preserve the section as-is instead of falling through to full replace - Add tests for keep preservation and no-keep replacement Co-Authored-By: Claude Opus 4.6 (1M context) * fix: address PR #1508 review findings (F1-F5) Refactor the keep-marker stats-update path and close the test-coverage gaps surfaced by the production-readiness review. ## Findings 2 + 3 (high) — fragile extraction → silent corruption Stop re-extracting `newName` (first `**bold**`) and `newStats` (first `(...)`, with fallback) from generated content. Both are structurally fragile: - F2: newName silently picks the wrong value if the template ever emits bold text before the project-name line (no current bug; an unstated contract with no enforcement) - F3: newStats fallback `\(([^)]+)\)` matches `({target: "symbolName", direction: "upstream"})` from the Always-Do bullet when `noStats: true` suppresses the canonical stats line, silently corrupting the stats output Fix: pass `projectName: string` and `stats: RepoStats` directly into `upsertGitNexusSection`. Build the stats line from those values. Both callers in `generateAIContextFiles` already have them in scope. ## Finding 1 (high) — misleading return value When a keep marker is present but no stats line matches the pattern, the function previously returned `'updated'` without writing, producing `CLAUDE.md (updated)` in CLI output for a file that was not touched. Add a distinct `'preserved'` return variant; CLI now reports `CLAUDE.md (preserved)` honestly. ## Finding 4 (medium) — unanchored stats regex `/(?:Indexed as|...) \*\*[^*]+\*\* \([^)]+\)/` could match prose embedded mid-paragraph in user content (e.g. "you'll see it Indexed as **Foo** (note: ...)"). Anchor with `^...$` plus the `m` flag so only standalone stats lines match. ## Finding 5 — test coverage gaps Seven new tests, each cross-referenced to the review finding: - keep marker OUTSIDE the GitNexus section has no effect - AGENTS.md keep path preserves custom layout (parity with CLAUDE.md) - idempotent: second run produces byte-identical output - CRLF file with keep marker: stats line updates correctly - noStats + keep marker: not corrupted by Always-Do tuple text (F3 regression guard) - returns 'preserved' (not 'updated') when no stats line matches (F1 regression guard) - project name with markdown punctuation (hyphens/slash/dot) lands intact All 23 ai-context tests pass; typecheck, prettier, eslint clean. * docs(ai-context): address PR #1508 review findings on keep-marker path - Clarify that noStats affects generated template only, not keep-section stats updates - Fix stats-line regex comment to match behavior (no end anchor; trailing suffix kept) - Assert '. MCP tools.' survives stats replacement in preserve-custom-section test - Document LF normalization when rewriting CRLF seed in keep-marker CRLF test Co-authored-by: Cursor --------- Co-authored-by: Claude Opus 4.6 (1M context) Co-authored-by: dp-web4 Co-authored-by: Gergő Magyar Co-authored-by: Cursor --- gitnexus/src/cli/ai-context.ts | 53 ++++- gitnexus/test/unit/ai-context.test.ts | 310 +++++++++++++++++++++++++- 2 files changed, 358 insertions(+), 5 deletions(-) diff --git a/gitnexus/src/cli/ai-context.ts b/gitnexus/src/cli/ai-context.ts index 8e18fed7d..42dcb7aa7 100644 --- a/gitnexus/src/cli/ai-context.ts +++ b/gitnexus/src/cli/ai-context.ts @@ -199,7 +199,9 @@ async function fileExists(filePath: string): Promise { async function upsertGitNexusSection( filePath: string, content: string, -): Promise<'created' | 'updated' | 'appended'> { + projectName: string, + stats: RepoStats, +): Promise<'created' | 'updated' | 'appended' | 'preserved'> { const exists = await fileExists(filePath); if (!exists) { @@ -223,7 +225,50 @@ async function upsertGitNexusSection( ); if (startIdx !== -1 && endIdx !== -1 && endIdx > startIdx) { - // Replace existing section + const existingSection = existingContent.substring( + startIdx, + endIdx + GITNEXUS_END_MARKER.length, + ); + + // If the existing section contains , preserve the user's + // custom layout and only update the stats line (node/edge/flow counts). + // This lets teams trim the verbose default template to a lean format without + // having it overwritten on every `gitnexus analyze`. + // + // Note: the keep-marker check operates on `existingSection` (the substring + // between valid section markers identified by findSectionMarkerIndex), so + // a keep marker in user prose OUTSIDE the GitNexus block has no effect. + if (existingSection.includes('')) { + // Build the new stats line from the caller-provided values directly. + // We do NOT re-extract from `content` because: + // (a) first-bold extraction is fragile if the template evolves + // (b) the parenthesized-text fallback can match unrelated tuples + // like `({target: "symbolName", direction: "upstream"})` + // when noStats is set + // Passing projectName + stats explicitly makes the contract obvious. + // noStats controls template generation, not keep-section stat updates — the user opted into a stats line by keeping it. + const newStatsInner = `${stats.nodes || 0} symbols, ${stats.edges || 0} relationships, ${stats.processes || 0} execution flows`; + const statsLine = `Indexed as **${projectName}** (${newStatsInner})`; + + // Match either canonical phrasing at line start (`^` with `m` flag) so we + // cannot replace prose embedded mid-paragraph.

The `--no-stats` flag on `gitnexus analyze` was advertised as "Omit volatile file/symbol counts from AGENTS.md and CLAUDE.md" but had no effect: every reindex still rewrote the markdown with fresh count phrases, producing chore-commit churn on every run — the exact problem the flag was added to solve in #704. Root cause is commander.js negation-flag semantics. `.option( '--no-stats', ...)` registers the option under the accessor `stats` (boolean, default `true`; `false` when the flag is passed), NOT `noStats`. The two action-handler reads in `analyze.ts` (lines 414 and 500 pre-fix) read `options?.noStats`, which is always `undefined`, so the `noStats` payload always reached `runFullAnalysis` / `generateAIContextFiles` as `undefined`/falsy and the count branch in the template always fired. Fixed by replacing `options?.noStats` with `options?.stats === false` at both reads. The strict `=== false` check (rather than `!options?.stats`) means absent options or absent `.stats` field fall through as no-stats=false, preserving the documented default-on behaviour. Also updated the `AnalyzeOptions` interface to declare `stats?: boolean` (matching commander's actual output) with a JSDoc explaining the negation, since the prior `noStats?: boolean` shape was a static-type misrepresentation of what commander provides at runtime. Internal call sites that re-pack `{ noStats: ... }` for downstream consumers (`run-analyze.ts`, `ai-context.ts`) keep their existing field name — those interfaces are not commander- shaped, so `noStats` is the correct name there. ## Regression tests Two new unit tests in `test/unit/ai-context.test.ts`: * `omits volatile counts when noStats option is set (#1477)` — asserts the count parenthetical is absent from both CLAUDE.md and AGENTS.md when `noStats: true` is passed. * `preserves volatile counts when noStats is not set (default)` — documents the default-on path so a future refactor can't silently flip the default. Both call `generateAIContextFiles` directly with distinctive numbers that would unmistakably leak through if the omit branch is broken. ## Manual verification * `vitest run test/unit/ai-context.test.ts` → 13/13 pass (11 prior + 2 new). * Verified before-fix behaviour by checking out main, running `npx gitnexus analyze --no-stats` against an indexed repo, and observing the count phrase still present. Re-running on the fix branch with the same flag strips the phrase as documented. Co-Authored-By: Claude Opus 4.7 (1M context) * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(cli): resolve merge conflict markers in analyze.ts (PR #1478) Remove leftover conflict hunks from main merge; keep commander stats shape (stats?: boolean), wire noStats: options?.stats === false into runFullAnalysis and generateAIContextFiles, and retain indexOnly / skipSkills / skipAgentsMd wiring from main. Co-authored-by: Cursor * test(cli): cover analyzeCommand → runFullAnalysis noStats bridge (#1477) Assert commander-shaped options.stats maps to the internal noStats payload (including explicit true/false and skipAgentsMd combination) so the CLI bridge cannot regress without failing tests.

charset=UTF-8 Content-Transfer-Encoding: 8bit * 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> — 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 — 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::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 deriving from Base, 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` → `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::method()` and `outer::v1::Base::f()`. Three fixtures + four tests: - `cpp-phase5-u1-u3-qualified-base-call`: `template struct Derived : Base` with `Base::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` as a super candidate, but the empty-MRO terminates without false edges. - `cpp-phase5-u2-u3-adl-from-derived`: `Derived : Base` 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 struct Derived : outer::v1::Base` where `v1` is inline. Unqualified `f()` inside `Derived::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:

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix: apply ESM .js extension fallback to tsconfig path alias resolution Path alias imports (e.g. `@/utils.js` via tsconfig paths) now correctly strip JS-family extensions and retry with TS equivalents when the literal .js file does not exist. This applies the same stripJsExtension fallback already used for relative imports to the alias resolution branch. Fixes #1528 * chore(autofix): apply prettier + eslint fixes via /autofix command * test(esm): cover .mjs/.cjs path-alias extension resolution Co-authored-by: Cursor * test(esm): use Map for path aliases in resolveWithAlias helper Matches TsconfigPaths.aliases from language-config. CI cannot run tsc -p tsconfig.test.json yet: the project has hundreds of pre-existing errors under test/ (fixtures + unit/integration); enable that step after backlog cleanup.

P1: - Plugin copy of `win-rm-list-json.ps1` gains `Pack = 4` so its CLR struct matches the 12-byte native `RM_UNIQUE_PROCESS` layout (multi-blocker `RmGetList` no longer reads mangled `dwProcessId`). - `GITNEXUS_HOOK_CLI_PATH = ''` now falls through to the resolution chain in `gitnexus-hook.cjs`, matching the plugin copy and removing the twin-file divergence on empty-string envs. - Lock-warning suppression test seeds `gitnexusMarkerPath` and asserts the augment subprocess actually ran, plus `GITNEXUS_DEBUG=1` preserves the full discarded prefix. - MCP-owner skip branch in both hook copies now emits `[GitNexus] augment skipped: MCP server owns DB` on stderr, so agents can distinguish intentional skip from silent failure. P2: - `ps` loop in `hook-db-lock-probe.cjs` fails-closed on `ETIMEDOUT` to mirror the `lsof` handling (symmetric subprocess-probe contract). - `RmStartSession` return value captured in both `.ps1` copies; exits early with `[]` on non-zero so subsequent RM API calls don't operate on an invalid handle. - Windows RM-list `.ps1` encoded cache distinguishes uninitialized (`undefined`) from load-failed (`null`) with a one-shot `GITNEXUS_DEBUG` warning instead of silently caching empty string. - `createHookToolDir` helper accepts `lsofOutputLines` and `psOutputByPid`; the multi-PID test uses them instead of duplicating the fake-binary construction inline. - All five skip-path tests now assert `result.status === 0` and the new skip-signal stderr line. - `AGENTS.md` documents the seven hook configuration env vars (`GITNEXUS_HOOK_CLI_PATH`, `_LSOF_PATH`, `_PS_PATH`, `_POWERSHELL_PATH`, `_LINUX_PROC_BUDGET_MS`, `_RM_TARGET`, `GITNEXUS_DEBUG`). - `GITNEXUS_DEBUG` path in `gitnexus-hook.cjs`/`.js` writes the full discarded stderr prefix instead of a 180-char preview. - Inline comment in `hook-db-lock-probe.cjs` explains the intentional Windows ETIMEDOUT fail-closed semantics. - Removed the unnecessary `as WriteFileOptions` cast and orphaned `import type { WriteFileOptions }` in `hooks.test.ts`. P3: - `isGitNexusServerCommand` unexported from `hook-db-lock-probe.cjs` (kept as private helper). - Env-path overrides (`GITNEXUS_HOOK_CLI_PATH`, `_POWERSHELL_PATH`, `_LSOF_PATH`, `_PS_PATH`) require `fs.existsSync` before being returned, so typos / stale config fall through to the standard resolution chain. Misc: - `gitnexus/package.json` engines.node back to `>=22.0.0` (matches origin/main and the original PR reviewer's earlier request).

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(cli): tolerate read-only workspace in ensureGitNexusIgnored The documented Docker workflow mounts the host workspace at /workspace:ro and runs `gitnexus index /workspace/` against an index produced by a prior host-side `analyze`. Since PR #1248 ("keep GitNexus ignores inside .gitnexus") the index command has called `ensureGitNexusIgnored`, which unconditionally writes `/.gitnexus/.gitignore` and `/.git/info/exclude` — both fail with EROFS on the :ro bind mount even though the host already wrote the correct file during `analyze`. Two complementary changes: 1. Idempotent fast path. Read the existing .gitnexus/.gitignore content first; if it already matches the desired value (`*\n`), skip the write entirely. This is the common case for the Docker workflow and avoids touching the FS at all. 2. EROFS/EACCES tolerance. When a write is genuinely needed but the FS refuses it, log a structured warning via the existing pino logger and continue. `registerRepo` runs before `ensureGitNexusIgnored` in `indexCommand`, so the global-registry write is already committed when we get here — letting the gitignore-write failure propagate leaves the user with a registered-but-error-exited command. Three new unit tests pin the behaviour: - idempotent re-call leaves mtime untouched - ENOENT-then-correct path on a writable parent succeeds - :ro parent (simulated via chmod 0o555) does not throw, on the already-correct fast path and on the cold-create path Existing tests (61) still pass. Closes #1549. * test(storage): cover read-only ignore paths and tolerate EPERM (#1550) - Add isReadOnlyFilesystemError helper including EPERM alongside EROFS/EACCES for ensureGitNexusIgnored and ensureGitInfoExclude (Windows parity with lbug-config / bridge-db patterns). - Skip chmod-based read-only tests on win32 and uid 0; assert logger.warn on POSIX chmod denial for missing .gitignore. - Add repo-manager-ensure-ignore-readonly.test.ts with vi.mock fs/promises delegating writeFile so EROFS/EACCES/EPERM rejections are asserted with structured log path and message for both .gitignore and .git/info/exclude.

The registry-primary path was filtering these defs out of `expandCppWildcardNames` via both the structural Namespace-owner check and the `isFileLocal` mark, so `hidden_probe(d)` from a TU including the header resolved to nothing while the legacy DAG returned the correct edge. Track anonymous-`namespace_definition` source ranges at capture time, resolve them to ScopeIds in `populateOwners` (parallels inline-namespace handling), and exempt those scopes from the two wildcard-expansion filters plus the `populateCppNonGloballyVisible` structural set. `markFileLocal` is preserved so the global free-call fallback still blocks cross-TU leaks for files that do NOT #include the declaring file (cpp-anon-ns-cross-file guard still passes). --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: magyargergo <11230420+magyargergo@users.noreply.github.com> Co-authored-by: Gergo Magyar --- .../src/core/ingestion/languages/cpp/adl.ts | 38 +++++--- .../core/ingestion/languages/cpp/captures.ts | 33 +++++-- .../languages/cpp/file-local-linkage.ts | 90 ++++++++++++++++++- .../ingestion/languages/cpp/scope-resolver.ts | 8 +- .../app.cpp | 14 +++ .../base_lib.h | 11 +++ .../app.cpp | 16 ++++ .../base_lib.h | 6 ++ .../app.cpp | 22 +++++ .../base_lib.h | 20 +++++ .../test/integration/resolvers/cpp.test.ts | 86 ++++++++++++++++++ .../test/integration/resolvers/helpers.ts | 6 -- .../resolver-parity-expected-failures.test.ts | 15 ++++ 13 files changed, 337 insertions(+), 28 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-collision/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-collision/base_lib.h create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-negative/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces-negative/base_lib.h create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-adl-base-associated-namespaces/base_lib.h diff --git a/gitnexus/src/core/ingestion/languages/cpp/adl.ts b/gitnexus/src/core/ingestion/languages/cpp/adl.ts index bb28c3853..fd65ae51e 100644 --- a/gitnexus/src/core/ingestion/languages/cpp/adl.ts +++ b/gitnexus/src/core/ingestion/languages/cpp/adl.ts @@ -21,8 +21,9 @@ * - `audit::Event& r`, `audit::Event&& rr` * - `std::vector` (template namespace + template-arg namespaces) * - * Function-pointer arguments, base-class associated namespaces, and the rest - * of the full closure are still deliberately excluded. + * Function-pointer arguments and the rest of the full closure are still + * deliberately excluded.

Per ISO C++ `[basic.lookup.unqual]` §7, ADL is blocked only when ordinary lookup itself finds a non-function — if ordinary lookup stops at an inner scope where only callables exist, ADL should still fire. Replace the separate `hasNonCallableBindingInScope` + `findAllCallable BindingsInScope` calls with a combined `findCallableBindingsAndAdlBlocker` walker that stops at the first scope with ANY binding for the name and returns both `{ callables, nonCallableFound }`. One pass, one stop. Fixture: cpp-adl-inner-callable-outer-noncallable — inner scope has callable `swap(int,int)`, outer scope has `int swap = 0`. ADL fires and resolves to `data::swap(Pair&,Pair&)` via argTypes narrowing.

charset=UTF-8 Content-Transfer-Encoding: 8bit Collapse release-candidate.yml into publish.yml so there is exactly one workflow that publishes gitnexus to npm, creates GitHub Releases, and triggers Docker builds — for both release candidates and stable releases. Closes #1609 architecturally. A first-stage `route` job classifies push-to-main / push-tag / workflow_dispatch into `rc` / `stable` modes and fails closed on malformed shapes. RC path runs rc-guard → ci.yml → publish (mint GitHub App token → checkout with persist-credentials:false → resolve next rc version → atomic v-tag + rc/ marker push → vtag integrity gate → npm publish via OIDC → GitHub prerelease → if: failure() cleanup) → docker.yml. Stable path verifies package.json matches the tag and publishes to `latest` via OIDC (no docker). Hardening: • Self-trigger prevention via negative-glob `tags: ['v*', '!v*-rc.*']` — the bug class behind #1609 cannot recur. • Two distinct actions/checkout steps per mode (no conditional `token:` expression footgun). • Workflow-level `permissions: {}` deny-all + per-job grants; `id-token: write` only where OIDC is used. • npm Trusted Publishing replaces NPM_TOKEN (delete the secret after the first successful publish). • GitHub App installation token (actions/create-github-app-token@v3.2.0) replaces the long-lived RELEASE_PUSH_TOKEN PAT (delete after first successful RC). • vtag integrity gate fails closed on empty / mode-mismatched output (prevents Release named `main` from a github.ref fallback). • Annotation-injection sanitization on every logged ref. • Explicit `secrets:` passthrough on docker.yml (DOCKERHUB_USERNAME, DOCKERHUB_TOKEN); ci.yml no longer inherits anything. • `if: failure()` cleanup auto-deletes v-tag + rc-marker on partial failure (eliminates the external-consumer phantom-version ingestion window). • ACTIONS_STEP_DEBUG window closed via `set +x` wrap on the inline auth-header compute. • Curated retry-loud error handling on `gh api` bot-user-id lookup and `npx semver`. Pre-merge validation: • 10-reviewer multi-agent code-review pass; 14 findings fixed inline (commit 820cefae), 6 deferred to follow-ups. • End-to-end dry-run rehearsal via workflow_dispatch (run 25919563064) validated route classification, rc-guard, App token mint, RC checkout, version resolver, vtag synthetic-regex check, and faithful tarball pack at the bumped version. • All zizmor findings on the unification commits closed. • Branch-protection required checks all green. Post-merge actions: • After the first successful RC, delete the `NPM_TOKEN` and `RELEASE_PUSH_TOKEN` secrets — they are no longer used. • The first real RC after merge is the live-fire test for steps dry-run could not exercise (atomic tag push, real npm OIDC handshake, GitHub Release creation, docker.yml under explicit secrets passthrough). The if: failure() cleanup step handles the partial-failure recovery automatically; the Rollback Runbook in CONTRIBUTING.md covers the rare cases auto-cleanup can't reach. --- .github/workflows/ci.yml | 16 +- .github/workflows/docker.yml | 11 +- .github/workflows/publish.yml | 834 +++++++++++++++++++++++- .github/workflows/release-candidate.yml | 459 ------------- .github/zizmor.yml | 9 +- CONTRIBUTING.md | 84 ++- README.md | 4 +- 7 files changed, 884 insertions(+), 533 deletions(-) delete mode 100644 .github/workflows/release-candidate.yml diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index dd07337b7..c28e49be9 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -11,14 +11,14 @@ permissions: # Concurrency convention: see CONTRIBUTING.md → "GitHub Actions — Concurrency Convention". # Hardcoded `CI-` prefix (not `${{ github.workflow }}`) because this workflow is -# invoked as a reusable workflow from publish.yml and release-candidate.yml.

The if: failure() cleanup correctly auto-deleted the partial v-tag and rc-marker, but OIDC never engaged. Root cause: two coordinated upstream bugs. 1. actions/setup-node@v6 with registry-url: writes _authToken into the runner .npmrc AND exports NODE_AUTH_TOKEN from its token: input (defaulting to github.token). npm publish sends GITHUB_TOKEN as the bearer and the registry returns 404.

When exceeded, the phase gracefully stops and logs a warning. Users can override via GITNEXUS_CROSS_FILE_TIMEOUT_MS env var. This prevents the analyze command from stalling for hours on very large repositories where per-file re-resolution is expensive. Fixes the reported issue where gitnexus analyze stalls at "Cross-file type propagation" for several hours on repos with 15000+ files.

Additionally, progress was only reported once at the start, making the phase appear completely frozen. Fixes: - Add optional `compiledQueryCache` parameter to `processCalls` so callers that invoke it with single-file batches can share compiled query objects across calls. The cross-file phase now compiles each language's query string exactly once and reuses it for all files of that language (e.g. 1 TypeScript compile for 595+ files). - Pre-count candidate files and emit onProgress every 25 files showing "Cross-file type propagation (N/M files)..." so the UI shows real movement instead of a frozen bar. - Keep the wall-clock deadline (GITNEXUS_CROSS_FILE_TIMEOUT_MS) as a safety net for pathological inputs.

MAX_CROSS_FILE_REPROCESS (2000) remains as the only cap. * test(cross-file): verify compiledQueryCache is shared across all processCalls invocations Finding 1: O(N) query recompilation was fixed by sharing a compiledQueryCache Map across all processCalls invocations in runCrossFileBindingPropagation.

Fix: check isRegistryPrimary(lang) in both the totalCandidates pre-count loop and the levelCandidates builder, before any file I/O or map building. This eliminates 595+ no-op processCalls invocations on large TypeScript repos. Test: mocks isRegistryPrimary to always return true and verifies that processCalls is never invoked and result is 0. The mock also defaults to false in beforeEach so existing tests using .ts files are unaffected.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(cpp): add standard-conversion-sequence ranking to overload resolution (#1578) Introduce `ConversionRankFn` abstraction and `cppConversionRank` implementation to disambiguate C++ overloaded calls by argument-to-parameter conversion cost. Exact type match (rank 0) beats standard arithmetic conversion (rank 2), which beats non-viable mismatch (Infinity). Thread the rank function through `narrowOverloadCandidates`, `pickImplicitThisOverload`, `pickOverload`, and `pickUniqueGlobalCallable` via the `ScopeResolver.conversionRankFn` contract. Add `findAllCallableBindingsInScope` scope walker for collecting all overloads at the first binding scope. Guard against false ambiguity suppression when candidates span different files (local-shadows-import preservation). * fix: address Claude review findings on conversion-rank PR Finding 1 (HIGH): add tests that exercise the conversion ranker. - p('a') with p(int)/p(double): char→int promotion (rank 1) beats char→double conversion (rank 2), forcing step 4b in narrowOverloadCandidates. Exact-type filter misses both overloads. - h(42, 2.5) with h(int,int)/h(double,double): multi-arg tied total score forces the ranker, both candidates score 2 → suppressed. Finding 2 (HIGH): unify multi-candidate suppression across all paths. - Non-ADL free-call: suppress when narrowed.length > 1 (same-file guard), mirroring ADL merged-candidate behavior. - ADL ordinary-only: same pattern. - pickOverload: return OVERLOAD_AMBIGUOUS when candidates.length > 1 after normalized-ambiguity check. - Case 0.5 (this receiver): set ambiguous=true when narrowed > 1. Finding 3+4 (MEDIUM): implement rank-1 integral promotions. - char→int and bool→int now return rank 1 (ISO C++ [conv.prom]). - Updated comment to remove misleading ISO table header; document only the post-normalization ranking that is actually implemented. - Updated ConversionRankFn JSDoc in overload-narrowing.ts. 218/218 C++ tests pass (registry-primary). Legacy: 186+32. * fix: implement pairwise dominance comparison for overload ranking Replace the summed per-slot conversion cost with ISO C++-aligned pairwise dominance comparison ([over.ics.rank]). F1 is better than F2 only when F1 is not worse for every argument and strictly better for at least one. Non-dominated candidates are returned; if multiple remain they are genuinely ambiguous. This fixes false CALLS edges for asymmetric multi-arg overloads: h('a', 2.5) against h(int,int) / h(double,double) — the old summed cost picked h(double,double) (cost 2 < 3), but ISO C++ considers the call ambiguous because h(int,int) is better at arg 0 via char promotion. The pairwise check correctly finds neither dominates. Add h('a', 2.5) test case asserting zero CALLS edges alongside the existing h(42, 2.5) symmetric-tie test. 218/218 C++ tests pass (registry-primary). Legacy: 186+32. * docs: update step 4b JSDoc to reflect pairwise dominance --------- Co-authored-by: Gergő Magyar --- .../languages/cpp/conversion-rank.ts | 47 ++++++ .../ingestion/languages/cpp/scope-resolver.ts | 5 + .../contract/scope-resolver.ts | 15 ++ .../passes/free-call-fallback.ts | 135 +++++++++++++++--- .../passes/overload-narrowing.ts | 107 ++++++++++++++ .../passes/receiver-bound-calls.ts | 29 +++- .../scope-resolution/pipeline/run.ts | 1 + .../cpp-overload-conversion-rank/lib.cpp | 10 ++ .../cpp-overload-conversion-rank/lib.h | 33 +++++ .../test/integration/resolvers/cpp.test.ts | 74 ++++++++++ .../test/integration/resolvers/helpers.ts | 13 ++ 11 files changed, 446 insertions(+), 23 deletions(-) create mode 100644 gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-overload-conversion-rank/lib.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-overload-conversion-rank/lib.h diff --git a/gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts b/gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts new file mode 100644 index 000000000..2a9e3bc01 --- /dev/null +++ b/gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts @@ -0,0 +1,47 @@ +/** + * C++ conversion-rank scoring for overload resolution (#1578). + * + * Operates on **normalized** type strings (output of + * `normalizeCppParamType` in `arity-metadata.ts`).
