Previously, GitNexus used only a hardcoded ignore list, causing significant index pollution in repositories with git-ignored directories containing code (e.g., Docker-mounted volumes). Changes: - Add `ignore` package for gitignore-spec pattern matching - Add `loadIgnoreRules()` to parse .gitignore + .gitnexusignore - Add `createIgnoreFilter()` returning glob-compatible IgnoreLike object - Integrate filter into glob's `ignore` option for directory-level pruning - Remove post-glob `.filter()` call (now handled during traversal) The hardcoded DEFAULT_IGNORE_LIST remains as fallback for non-git repos. Closes #228 Co-Authored-By: Claude Opus 4.6 * fix(ingestion): address review feedback on ignore filtering - Distinguish ENOENT vs EACCES in loadIgnoreRules (warn on permission errors) - Add GITNEXUS_NO_GITIGNORE env var to bypass .gitignore parsing - Fix bare-name pattern matching in childrenIgnored (check both with/without trailing slash) - Rename isIgnoredDirectory to isHardcodedIgnoredDirectory for clarity - Add clarifying comments for design decisions (D2 negation, D3 dot:false redundancy) - Add tests for bare-name patterns, file-glob patterns, EACCES handling, env var Co-Authored-By: Claude Opus 4.6 * fix(ingestion): address second round of review feedback - G1: Document GITNEXUS_NO_GITIGNORE in `analyze --help` and log when active - G2: Add comment clarifying path-scurry POSIX normalization contract - G3: Add IgnoreOptions interface — env var now falls back, callers can pass `noGitignore` explicitly for testability and future CLI flag - G4: Add integration test verifying walkRepositoryPaths respects the env var Co-Authored-By: Claude Opus 4.6 * feat(ingestion): gracefully skip files with unavailable tree-sitter grammars Port unsupported language resilience from PR #301 by @jecanore. - Make Kotlin import optional (like Swift) in parser-loader and parse-worker - Add worker-local isLanguageAvailable() with filePath param for tsx distinction - Track and log skipped files per language in both sequential and worker paths - Add skippedLanguages to ParseWorkerResult for worker→main aggregation - Add isLanguageAvailable unit tests Refs: #301, #155, #228 Co-Authored-By: jecanore Co-Authored-By: Claude Opus 4.6 * test(e2e): add ignore + language-skip end-to-end test with fixture repo Add a fixture repo (test/fixtures/ignore-and-skip-repo/) with .gitignore, .gitnexusignore, TypeScript source files, and a Swift file to exercise all three features end-to-end: - File discovery: verifies .gitignore excludes data/ and *.log, .gitnexusignore excludes vendor/, source files are discovered - Parsing: verifies TypeScript files produce Function nodes and DEFINES relationships, Swift files are skipped gracefully when grammar is unavailable Add the test to the standalone group in ci-integration.yml and coverage job. Co-Authored-By: Claude Opus 4.6 * fix(ci): move ignore-and-skip-e2e test to e2e group per review feedback Co-Authored-By: Claude Opus 4.6 * fix(test): use temp directory instead of fixture for e2e ignore test The fixture's .gitignore prevented data/seed.json and debug.log from being committed — these files would be missing after checkout in CI. Switch to creating the entire test structure in a temp directory via beforeAll (matching filesystem-walker.test.ts pattern). This ensures all files exist regardless of git ignore rules. Co-Authored-By: Claude Opus 4.6 * fix(test): correct graph API usage in e2e ignore test Use graph.nodes property getter instead of graph.getNodes(), and check Function node filePath instead of non-existent File nodes (File nodes are created by processStructure, not processParsing). Co-Authored-By: Claude Opus 4.6 * ci: add workflows permission to ci-integration.yml Co-Authored-By: Claude Opus 4.6 * ci: change workflows permission to write per review Co-Authored-By: Claude Opus 4.6 * ci: move workflows permission from ci-integration.yml to ci.yml caller Co-Authored-By: Claude Opus 4.6 * fix(ci): fix Claude workflows for fork PRs, remove misplaced workflows perm Three issues prevented Claude from running on fork PRs: 1. claude-code-review.yml lacked workflows:write — push failed when fork PRs modify .github/workflows/ files 2. claude.yml had no fork PR support — checked out main and couldn't fetch the fork's branch from origin 3. Cleanup step unconditionally deleted branches even when push failed, breaking the concurrent claude.yml workflow Also removes workflows:write from ci.yml's integration job — CI tests don't need that permission. The permission belongs on the claude workflows that push fork branches. Changes: - Add workflows:write to both claude workflow permissions blocks - Add fork PR detection + branch push/cleanup to claude.yml - Add step id to push-fork; cleanup only runs if push succeeded - Pass branch names via env vars to prevent shell injection (security) - Add concurrency groups to prevent race conditions between workflows - Remove misplaced workflows:write from ci.yml integration job * fix(ci): use GitHub API for fork branch refs instead of git push GITHUB_TOKEN cannot have 'workflows' permission — it's only valid for PATs and GitHub Apps. This means git push fails whenever a fork PR modifies .github/workflows/ files. Replace git push with the GitHub REST API (POST/PATCH /git/refs) to create temporary branch refs. The API creates a pointer to the already-existing PR head commit without triggering the workflow file push protection. Similarly, cleanup uses DELETE /git/refs instead of git push --delete. Also removes the invalid 'workflows: write' from permissions blocks. --------- Co-authored-by: Claude Opus 4.6 Co-authored-by: jecanore Co-authored-by: Gergo Magyar --- .github/workflows/ci-integration.yml | 4 +- .github/workflows/claude-code-review.yml | 42 +++- .github/workflows/claude.yml | 77 +++++- gitnexus/package-lock.json | 10 + gitnexus/package.json | 1 + gitnexus/src/cli/analyze.ts | 4 + gitnexus/src/cli/index.ts | 1 + gitnexus/src/config/ignore-service.ts | 92 +++++++ .../src/core/ingestion/filesystem-walker.ts | 9 +- .../src/core/ingestion/parsing-processor.ts | 32 ++- .../core/ingestion/workers/parse-worker.ts | 57 +++-- .../src/core/tree-sitter/parser-loader.ts | 7 +- .../integration/filesystem-walker.test.ts | 158 ++++++++++++ .../integration/ignore-and-skip-e2e.test.ts | 152 ++++++++++++ gitnexus/test/unit/ignore-service.test.ts | 226 +++++++++++++++++- gitnexus/test/unit/language-skip.test.ts | 48 ++++ 16 files changed, 884 insertions(+), 36 deletions(-) create mode 100644 gitnexus/test/integration/ignore-and-skip-e2e.test.ts create mode 100644 gitnexus/test/unit/language-skip.test.ts diff --git a/.github/workflows/ci-integration.yml b/.github/workflows/ci-integration.yml index e7da8049a..2537ac77e 100644 --- a/.github/workflows/ci-integration.yml +++ b/.github/workflows/ci-integration.yml @@ -24,7 +24,7 @@ jobs: # process.exit().

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: Phase 4 type resolution — nullable unwrapping, for-loop typing, assignment chains, Kotlin return types Phase 4.1: Nullable/optional chain unwrapping - Add stripNullable utility in shared.ts for stripping nullable wrappers - Apply in lookupInEnv to unwrap User | null → User, User? → User before receiver lookup - Handles TS union, Kotlin/C#/Swift nullable suffix, Python Union[T, None], Rust Option - Enables receiver-type disambiguation through ?. optional chaining Phase 4.2: For-loop element typing (Tier 0 — Java/C#/Kotlin) - Add ForLoopExtractor type and forLoopNodeTypes to LanguageTypeConfig - Java enhanced_for_statement, C# foreach_statement, Kotlin for_statement extractors - Only explicit element types in AST (Tier 0); inference-based languages deferred Phase 4.3: Assignment chain propagation (single-pass, depth-1) - Add PendingAssignmentExtractor to LanguageTypeConfig with per-language implementations - Handles TS/JS variable_declarator, Rust let_declaration, Python assignment, Go short_var_declaration, C# equals_value_clause, Java/Kotlin variable_declarator - Single post-walk propagation pass (no fixpoint iteration per Sorbet/Pyright design) - Resolves const b = a; b.save() when a has known type from Tier 0/1/1b Phase 4.5: Kotlin return type extraction (bug fix) - Fix extractMethodSignature to handle Kotlin user_type after function_value_parameters - Remove lenient test assertions, add strict disambiguation proof Integration tests across 10+ languages with competing same-name methods and negative assertions proving disambiguation. * fix: per-language assignment chain gaps from code review - Kotlin: new extractKotlinPendingAssignment for property_declaration → variable_declaration AST (Java's variable_declarator doesn't exist in Kotlin) - Go: handle var_spec (var b = u) alongside short_var_declaration (:=) - PHP: add extractPendingAssignment for $alias = $user with $ prefix preserved Integration tests added for all three languages with competing same-name methods and negative disambiguation assertions. * fix: code review fixes — DRY nullable keywords, avoid array allocations, clarify depth comment Addresses findings from 6-agent code review on PR #310: - Move stripNullable JSDoc to correct position (was orphaned above NULLABLE_KEYWORDS) - DRY: reuse NULLABLE_KEYWORDS set in pipe-split filter instead of inline strings - Replace node.children.find() with findChildByType/manual loops in jvm.ts, go.ts, csharp.ts to avoid unnecessary array allocations per tree-sitter call - Clarify "depth-1" comment in type-env.ts: single-pass resolves multi-hop chains when forward-declared; reverse-order is depth-1 only - Annotate extractGenericTypeArgs as Phase 5 infrastructure (zero production callers) - Re-export PendingAssignmentExtractor from index.ts for API consistency - Add explicit return undefined in Go extractPendingAssignment - Remove redundant child.text === '=' check in Kotlin extractor Test coverage: - 20 new unit tests: stripNullable edge cases, per-language assignment chains, reverse-order depth limitation, nullable lookup resolution - 15 new integration tests: multi-hop chains (a→b→c), nullable+chain combined (User|null + alias), Python User|None through stripNullable path - 3 new fixtures: ts-multi-hop-chain, ts-nullable-chain, python-nullable-chain * fix: third-pass review — walrus chain, scanner allocations, Kotlin variable_declaration, C# type guard Addresses 4 new findings from third-pass CI review: 1. Python walrus operator (:=) now handled by extractPendingAssignment — named_expression nodes propagate alias chains alongside regular assignment 2. Scanner .namedChildren.find()/.some() in jvm.ts replaced with findChildByType() — consistent with 98daed4 code review fixes 3. Kotlin extractPendingAssignment extended to handle variable_declaration nodes in addition to property_declaration (function-local val/var) 4. C# extractPendingAssignment early-returns for is_pattern_expression and field_declaration nodes (never contain variable_declarator children) Integration tests: - Python: walrus chain (alias := u) with disambiguation (5 tests, 1 fixture) - Kotlin: assignment chain with typed declarations (5 tests, 1 fixture) - C#: assignment chain + is-pattern coexistence (6 tests, 1 fixture) - Unit: Python walrus propagation (1 test) * feat: nullable wrapper unwrapping + C++ assignment chains Gaps 1, 2, 4 from code review — architectural changes to type resolution: 1. extractSimpleTypeName now unwraps nullable wrapper generics: - Optional → "User" (Java), Option → "User" (Rust), Maybe → "User" (Kotlin Arrow/Haskell-style) - Containers (List, Map) and async wrappers (Promise, Future) are NOT unwrapped — methods are called on the container, not the inner type - Uses existing extractGenericTypeArgs (now production-active, was dead code) - NULLABLE_WRAPPER_TYPES set: Optional, Option, Maybe 2. C++ extractPendingAssignment added for auto alias chains: - auto alias = user; alias.save() now propagates User type - Handles pointer/reference declarators, auto/decltype(auto) 3. Updated existing Rust test: Option parameter now correctly stores "User" instead of "Option" in TypeEnv Integration tests with fixtures for Java Optional, Rust Option, C++ auto chain. Full pipeline resolution marked .todo — requires call-processor enhancement (TypeEnv stores correct types but call-processor needs additional work to produce CALLS edges for these patterns). Unit tests: 196 passed (7 new). Integration: all 9 languages green. * fix: resolve .todo tests — stale dist/ was the root cause The Rust Option and C++ auto assignment chain integration tests were marked .todo because the pipeline didn't produce CALLS edges. Root cause: dist/ was compiled from pre-Phase 4 source and lacked: - NULLABLE_WRAPPER_TYPES unwrapping in extractSimpleTypeName - C++ extractPendingAssignment After npm run build, all tests pass as real assertions: - Rust: alias.save() resolves to User#save via Option unwrap + chain - C++: alias.save() and rAlias.save() resolve via auto assignment chain with correct disambiguation (User vs Repo) Only remaining .todo: Rust user.unwrap().save() (Phase 5 — chained return type inference, not a TypeEnv issue). --- gitnexus/src/core/ingestion/type-env.ts | 46 +-

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: Phase 5 type resolution — chained calls, pattern matching, class-as-receiver, code review fixes Phase 5.1: Chained method call resolution (depth-capped at 3) - resolveChainedReceiver() resolves a.getUser().save() by walking the chain and looking up intermediate return types from the SymbolTable - extractReceiverNode() + extractCallChain() shared in utils.ts - receiverCallChain on ExtractedCall for worker path parity - MAX_CHAIN_DEPTH=3 enforced in both extraction and resolution Phase 5.2: Pattern matching binding extractors - PatternBindingExtractor type added to LanguageTypeConfig - declarationTypeNodes map tracks original type AST nodes for generic unwrapping - Rust: if let Some(x)/Ok(x) unwrapping with extractGenericTypeArgs - Java: instanceof pattern variables (Java 16+) - C#: is-pattern disambiguation fixture (already working via extractDeclaration) Phase 5.5d: Python standalone type annotations (name: str) - expression_statement with type child now captured in DECLARATION_NODE_TYPES Phase 5.5e: ReceiverKey collision fix for overloaded methods - receiverKey preserves @startIndex to prevent same-name method collisions - lookupReceiverType does prefix scan with ambiguity refusal Class-as-receiver for static method calls (#289) - UserService.find_user() now resolves via ctx.resolve() tiered lookup - Respects import scoping — no false positives from unrelated packages Code review fixes: - Extracted CALL_EXPRESSION_TYPES + extractCallChain to utils.ts (eliminated duplication) - Converted resolveChainedReceiver from recursion to loop (no exposed depth param) - Added depth cap to extractReturnTypeName (defense against nested wrapper types) - Replaced lookupFuzzy with ctx.resolve for class-as-receiver (architecturally consistent) Closes #289 Test coverage: 6 new fixtures, 12+ new unit tests, 7 new integration test suites * fix: Ruby chain calls, Rust Err(x) unwrap, Enum class-as-receiver (#315) Address three per-language gaps identified in Phase 5 code review: - Ruby: add `method`/`receiver` field fallbacks to extractCallChain (tree-sitter-ruby uses different field names than other grammars) - Rust: handle `Err(e)` pattern binding via typeArgs[1] from Result - Enum: include Enum type in class-as-receiver filter (both paths) Integration tests added for all three fixes. * fix: chain base type resolution parity between serial and worker paths (#315) - Worker path: add typeEnv.lookup for chain base receiver after extraction (typed parameters like `fn process(svc: &UserService)` were silently lost) - Serial path: add ctx.resolve class-as-receiver fallback for chain base (class-name chains like `UserService.find_user().save()` failed) - Fix misleading comment in parse-worker.ts that described unimplemented logic - Integration tests: typed-parameter chain, static class-name chain * fix: Kotlin chain call extraction, createClassNameLookup Enum/Struct (#315) - Kotlin: extractCallChain now handles navigation_expression → navigation_suffix AST structure (Kotlin's call_expression has no 'function' field) - createClassNameLookup: include Enum and Struct alongside Class for consistent constructor recognition in extractInitializer - Integration test: kotlin-chain-call fixture verifying

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(resolver): prefer same-directory file for Python bare imports Python's sys.path searches the importing script's own directory first, so `import user` from services/auth.py should resolve to services/user.py even if models/user.py was indexed first in the suffix index. Add a proximity check in resolveImportPath that consults the existing dirMap index (O(1)) before falling back to global suffix matching, for single-segment bare Python imports only. Made-with: Cursor * refactor(resolver): replace dirMap scan with O(1) allFiles.has() for proximity check The previous implementation used index.getFilesInDir() + siblings.find() which had two issues: - dirMap stores all suffix levels, so getFilesInDir('services') matched files from every directory named 'services/' across the repo — false positives in monorepos - siblings.find() was an O(n) linear scan despite the O(1) claim Replace with a direct allFiles.has(importerDir + '/' + name + '.py') lookup. allFiles is a Set of full repo-relative paths, so the lookup is truly O(1) and exact — no suffix ambiguity possible. Also fixes: dead code (the '.rb' branch was unreachable since the outer if gates on Python), and Windows backslash handling via normalize before split. Made-with: Cursor * test: remove flag-based demo from unit tests Made-with: Cursor * fix(resolver): cover package __init__.py in proximity check and add end-to-end CALLS test - Also try importerDir/name/__init__.py as a second O(1) candidate so that `import user` resolves to services/user/__init__.py when the target is a package rather than a bare module file - Add unit tests for package proximity, __init__.py fallback, and Windows backslash path handling - Add end-to-end CALLS assertion to the bare-import integration test: svc.execute() must resolve to UserService#execute in services/user.py, proving the fix propagates correctly through the type inference pipeline Made-with: Cursor * refactor: extract Python import resolution into resolvers/python.ts - Move PEP 328 relative import and proximity-based bare import logic from standard.ts into a dedicated resolvers/python.ts (resolvePythonImport) - Dispatch Python imports from resolveLanguageImport in import-processor.ts, consistent with how Ruby, PHP, and other languages are handled - standard.ts is now language-agnostic (TS/JS aliases, Rust paths, suffix fallback) - Add inline comment on __init__.py vs .py resolution order edge case - Update unit tests to call resolvePythonImport directly Made-with: Cursor * docs: add PEP 302/328/451 references to python.ts comments Made-with: Cursor * fix(python): address reviewer comments on PEP compliance - Guard dirParts.pop() against over-traversal: return null when dot count exceeds directory depth, matching CPython's ImportError for 'attempted relative import beyond top-level package' (PEP 328) - Swap __init__.py / .py check order to match CPython's finder precedence (PEP 451 §4); coexistence is physically impossible so order only matters for spec compliance - Fix overstated PEP 302 comment: proximity check is a static heuristic, not a sys.path[0] implementation - Acknowledge namespace package gap (PEP 420) in docstring - Add unit test for over-traversal guard Made-with: Cursor * test(python): document namespace package resolution behaviour Add two unit tests for PEP 420 namespace packages (directory with no __init__.py): bare import returns null (expected — no file exists to resolve to, CPython sets __file__ = None), while the submodule form (import user.model) resolves correctly via suffixResolve fallback.

chain propagation - TS/JS: add for-loop Tier 1c for `for (const user of users)` with User[] inference - Python: add for-loop Tier 1c for `for user in users:` with type annotation inference - Go: add for-loop Tier 1c for `for _, user := range users` with []User inference - Fix 'Property' as any stale cast in call-processor.ts - Add dual return-type string length cap (2048 pre-cap, 512 post-cap) - Add chain call integration tests for C#, Go, Rust, Python, JS, C++ - Add Python match/case integration test fixtures - 27 new extractElementTypeFromString unit tests - 3 for-loop edge cases skipped (declarationTypeNodes scope key lookup) * fix: address code review findings for Phase 6 - Add missing patternBindingNodeTypes to C# typeConfig (perf gate) - Add 2048-char input length guard to extractElementTypeFromString - Skip Python match/case integration tests (call extraction needs query updates) * reorganise * fix: Phase 1 bug fixes — Go range semantics, typed_parameter, bracket depth - Go single-var range correctly returns early for slices/maps (index, not element) - Go single-var range on channels correctly resolves element type - Added map_type and channel_type to extractGoElementTypeFromTypeNode - Added isChannelType helper for channel detection before skip decision - Added 'typed_parameter' to TYPED_PARAMETER_TYPES for Python annotated params - Fixed bracket depth tracking in extractElementTypeFromString — only match selected closeChar at depth 0, return undefined for mismatched brackets - Un-skipped 3 prematurely skipped tests (TS local const, Python List/Sequence) - Added tests for map range, single-var range semantics, bracket edge cases * refactor: Phase 2 architecture — shared helper, required params, decoupled type nodes - Extract resolveIterableElementType shared helper in shared.ts implementing 3-strategy fallback (declarationTypeNodes → scopeEnv string → AST walk) - Refactor TS, Python, Go extractors to use shared helper (eliminates 3x duplication) - Make ForLoopExtractor params required (aligned with PatternBindingExtractor) - Update Java, Kotlin, C# extractor signatures to accept required params - Decouple declarationTypeNodes from scopeEnv — capture raw type annotation nodes BEFORE extractDeclaration for container types (User[], []User, List[User]) - Hybrid approach: direct name extraction + keysBefore fallback for multi-declarator - Document declarationTypeNodes invariant change (superset of scopeEnv) * feat: Phase 3 partial — Rust for-loop + C# var foreach Tier 1c - Rust: add extractForLoopBinding with for_expression support - Handles &users, &mut users via reference_expression unwrapping - extractRustElementTypeFromTypeNode: generic_type, reference_type, slice/array - findRustParamElementType: AST walk with reference/mut pattern unwrapping - 4 unit tests (Vec, &[User], range expr negative, no-annotation negative) - C#: upgrade foreach to handle var (implicit_type) via Tier 1c - extractCSharpElementTypeFromTypeNode: generic_name, array_type, nullable_type - findCSharpParamElementType: AST walk to method_declaration parameters - 3 unit tests (var foreach, explicit type regression, no-annotation negative) * feat: Phase 3 complete — all language gaps + pattern matching Kotlin Tier 1c: - Unannotated for-loop resolves via shared helper - extractKotlinElementTypeFromTypeNode handles type_projection unwrapping - findKotlinParamElementType walks to function_declaration Java Tier 1c: - var foreach resolves via shared helper - extractJavaElementTypeFromTypeNode handles generic_type, array_type - findJavaParamElementType walks to method_declaration TypeScript: - readonly User[] unwrapped via readonly_type → array_type recursion C# switch patterns: - declaration_pattern added to patternBindingNodeTypes - extractPatternBinding handles standalone declaration_pattern (switch case/expr) Rust match arms: - match_arm added to patternBindingNodeTypes - extractPatternBinding extended with match_arm → match_expression parent traversal Python: - as_pattern tries childForFieldName('alias') before positional fallback Tests: 237 pass (was 224), 13 new tests added * feat: Phase 4 — known limitation tests, match arm fix, final verification - Fix Rust match_arm pattern extraction: unwrap match_pattern to get tuple_struct_pattern inside (tree-sitter-rust wraps in match_pattern node) - Add first-writer-wins regression test for match arm scope leakage - Add 5 documented skip tests for known limitations: - TS destructured for-of (tuple destructuring) - Python tuple unpacking in for-loops - TS instanceof narrowing (block-level scoping) - Rust for with .iter() (method call iterable) - Ruby block parameters (closure param inference) Final: 238 passed, 5 skipped (documented limitations), tsc clean * test: integration tests for all Phase 6 language gaps + fix Rust param pattern field Integration test fixtures and tests (30 new tests, all with exact match + negative): Rust for-loop (5 tests): - for user in &users with Vec → User#save, negative Repo#save - for repo in &repos with Vec → Repo#save, negative User#save Rust match arm (5 tests): - match opt { Some(user) => user.save() } → User#save, negative Repo#save - if let Ok(repo) = res → Repo#save, negative User#save C# var foreach (5 tests): - foreach (var user in users) with List → User#Save, negative Repo#Save - foreach (var repo in repos) with List → Repo#Save C# switch pattern (4 tests): - is User user → User#Save, case Repo repo → Repo#Save Kotlin unannotated for (4 tests): - for (user in users) with List → user.save, negative repo.save Go map range (3 tests): - for _, user := range userMap with map[string]User → User#Save, negative TypeScript readonly (4 tests): - for (const user of users) with readonly User[] → user.save, negative Bug fix: type-env.ts parameter branch now falls back to childForFieldName('pattern') for Rust parameters (Rust uses 'pattern' not 'name' for parameter names) * test: add assertion bodies to known limitation skip tests Convert empty skip test stubs to proper tests with parse/buildTypeEnv/expect assertions following the codebase convention (e.g., call-processor.test.ts:319). Each skip test now documents the exact expected behavior, so removing .skip will cause a meaningful failure when the limitation is eventually fixed. Also clarify Python integration skip tests as call-extraction issues (not type-env) and Swift integration skips as build-dep issues (self/super resolution code already exists in type-env.ts). * feat: resolve 4 known limitation skip tests + method-aware type arg selection Unskip 4 of 5 type-env known limitations with full integration test coverage: 1. TS destructured for-of: handle array_pattern by binding last named child to element type. Fix Map to return last generic arg (value type). 2. Python dict.items() loop: handle `call` iterables + `pattern_list` left side. Fix dict[K,V] extraction via type_parameter with last-arg heuristic. Unwrap `type` wrapper in extractPyElementTypeFromAnnotation. 3. TS instanceof narrowing: add extractPatternBinding for binary_expression with positional child access. First-writer-wins (not block-scoped). 4. Rust .iter() for-loops: handle call_expression in for_expression value node by extracting receiver from field_expression. Method-aware type arg resolution: - Add TypeArgPosition ('first'|'last') to resolveIterableElementType - .keys()/.keySet()/.Keys → first type arg (key); all else → last (value) - Thread position through all 3 strategy callbacks in TS/Rust/Python - Add predefined_type to extractSimpleTypeName for TS primitives (string etc) New fixtures: rust-iter-for-loop, typescript-destructured-for-of, typescript-instanceof-narrowing, python-dict-items-loop. 248 unit tests pass (6 new), 1 skip (Ruby block params). * feat: container descriptor table for generic type arg resolution Replace simple KEY_METHODS heuristic with CONTAINER_DESCRIPTORS table that maps 30+ container types across all languages to their type parameter semantics per access method. Key improvements: - Container-aware resolution: HashMap.iter() correctly yields V (arity 2), while Vec.iter() yields T (arity 1) — same method, different semantics - Cross-language coverage: Map/HashMap/BTreeMap/dict/Dict/Dictionary/ ConcurrentHashMap + List/Vec/Set/HashSet/Queue/Deque/Stack etc. - Method categorization: keyMethods (keys/keySet/Keys) vs valueMethods (values/get/pop/iter/first/last) per container type - Fallback for unknown containers: still uses method name heuristic, so MyCache.keys() correctly returns first arg - Exported getContainerDescriptor() for future heritage-chain lookups Each language extractor now passes containerTypeName from scopeEnv to methodToTypeArgPosition for descriptor-aware resolution. 252 unit tests pass (4 new descriptor tests), 1 skip (Ruby). * feat: method-aware for-loop extractors + integration tests for all languages Upgrade 4 existing extractors + create 3 new ones for full cross-language coverage of call_expression iterables and container descriptor resolution: Upgraded (add call expr iterable + methodToTypeArgPosition): - Java: method_invocation (data.keySet(), data.values()) - Kotlin: navigation_expression + call_expression (data.keys, data.values()) - C#: member_access_expression + invocation_expression (data.Keys, data.Values) - Go: TypeArgPosition threading for Go 1.18+ generics New for-loop extractors: - C++: for_range_loop with auto& unwrapping, template_type + qualified_identifier (std::vector) extraction, explicit vs auto type handling - PHP: foreach_statement with simple/key-value/by-reference forms, PHPDoc @param priority over AST array type - Ruby: for-in with YARD @param type resolution via comment parsing Integration test fixtures + tests for all 6 languages: - java-map-keys-values (Map.values() + List iteration) - kotlin-map-keys-values (HashMap.values + List iteration) - csharp-dictionary-keys-values (Dictionary.Values foreach) - cpp-range-for (auto& + const auto& range-based for) - php-foreach-loop (foreach with PHPDoc @param User[]) - ruby-for-in-loop (for-in with YARD @param Array) Bugs fixed during integration testing: - C++: qualified_identifier (std::vector) not unwrapped to template_type - PHP: extractParameter overwrote PHPDoc-derived types with bare 'array' 252 unit tests pass, 201 integration tests pass across 6 languages. * fix: update extractElementTypeFromString tests for last-arg default TypeArgPosition change (default 'last') broke 5 existing tests expecting first arg from multi-arg generics. Updated expectations and added explicit pos='first' tests for key type extraction. * fix: rename C++ fixture files to correct case for case-sensitive CI On case-sensitive filesystems (Linux/macOS CI), git tracked both the old lowercase files (app.cpp, user.h) and the new uppercase files (App.cpp, User.h) as separate files. The pipeline processed both, causing the old app.cpp (with explicit User& type) to interfere with the new auto& test. Removes old lowercase entries and re-adds with uppercase casing to match the #include directives in the fixture. * feat: PR #318 review findings — pattern bindings, member access iterables, structured bindings Address all 7 genuine gaps identified in PR #318 deep code review: - Kotlin: add extractKotlinPatternBinding for when/is (type_test AST node) with allowPatternBindingOverwrite for smart-cast semantics - Java: add type_pattern branch for Java 17+ switch pattern variables - TypeScript: explicit object_pattern skip in for-of (no false bindings) - Cross-language: member access iterables (self.users, this.users, repo.users) across all 10 language extractors - C++: structured_binding_declarator handling in range-for (last-child heuristic) - Rust: closure_parameter added to TYPED_PARAMETER_TYPES - PHP: normalizePhpType handles angle-bracket generics (Collection) Code review fixes applied: - Remove 4 debug console.log statements (c-cpp.ts, call-processor.ts) - Hoist KNOWN_CONTAINER_PROPS to module scope (csharp.ts) - Guard keysBefore allocation behind typeNode check (type-env.ts) - Add depth limits (50) to 7 recursive type extraction functions - Add 2048-char length cap to extractSimpleTypeName - Fix PHP/Ruby missing typeArgPos parameter in resolveIterableElementType Integration test fixtures: kotlin-when-pattern, java-switch-pattern, cpp-structured-binding, typescript-member-access-for-loop, python-member-access-for-loop * fix: position-indexed when/is bindings, Kotlin param extraction, HashMap.values for-loop Three root causes for failing Kotlin integration tests: 1. When/is multi-arm resolution: flat scopeEnv stored only the last arm's type (last-writer-wins). Added PatternOverrides with AST range indexing so each when arm resolves to its narrowed type independently. 2. HashMap.values for-loop: navigation_expression without call_suffix was classified as bare property access (iterableName='values' instead of 'data'). Now tries object-as-iterable + property-as-method first, with fallback to property-as-iterable for this.users patterns. 3. Kotlin parameter extraction: tree-sitter-kotlin parameter nodes use positional children (simple_identifier, user_type) not named fields (name, type). Added fallback to findChildByType in both extractKotlinParameter and extractTypeBinding. Integration tests added for .keys/.values/Set/MutableMap iteration, 3-arm when/is, multi-call within arms, and when+else branch. * feat: enhance PHP type resolution for generics and member access in foreach loops * feat: Phase 6.1 type resolution gap closure — container descriptors, recursive_pattern, class fields Add 13 missing container type descriptors (Collection, MutableMap, Stream, SortedSet, etc.) to CONTAINER_DESCRIPTORS for correct element type extraction across C#, Kotlin, and Java. Extend C# pattern binding to handle recursive_pattern (obj is User { Name: "Alice" } u) in both is-expression and switch expression contexts. Add TypeScript class field declaration support (public_field_definition) so for-loop iteration over this.fieldName resolves element types from class field type annotations. Includes file-scope fallback in resolveIterableElementType and nested member_expression handling for this.field.method() patterns. * docs: add type resolution system documentation with roadmap Covers the full architecture, resolution tiers (0-2), scope model, language feature matrix, container descriptors, pipeline integration, and the Phase 7-9 roadmap for cross-scope propagation, field-type resolution, and return-type-aware binding. * feat: Phase 6.2 review findings — C# nested member foreach, C++ deref range-for, Java field_access Close two gaps found during fourth-pass review of PR #318: - C# foreach (var user in this.data.Values): nested member_access_expression now extracts intermediate property name for scopeEnv lookup - C++ for (auto& user : *ptr): pointer_expression dereference now recognized as range-for iterable Root causes fixed in shared infrastructure: - extractSimpleTypeName: add template_type (C++) and generic_name (C#) - extractGenericTypeArgs: add generic_name for consistency - type-env.ts: unwrap variable_declaration wrapper in field_declaration for declarationTypeNodes capture (zero-allocation manual loop) Additional review findings addressed: - Java: add field_access handler for this.data.values() in method_invocation - C++ pointer_expression: document limitation (*identifier only) - TypeScript: fix stale comment about property_identifier All 525 tests pass (278 unit + 247 integration). * perf: optimize type resolution pipeline — worker threshold, skip graph phases, AST pruning - Skip worker pool creation for small repos (<15 files or <512KB) — saves 100-400ms - Add skipGraphPhases option to runPipelineFromRepo to skip MRO/community/process phases - Add conservative SKIP_SUBTREE_TYPES for leaf-only AST nodes (string, comment, number) - Pre-compute interestingNodeTypes set — single Set.has() replaces 3 checks per node - Add fastStripNullable — skip full stripNullable for simple identifiers (90%+ case) - Replace .children?.find() with manual for loops in extractFunctionName (no array alloc) - Add hookTimeout: 120000 to vitest.config.ts for CI beforeAll hooks * fix: review findings — remove template_string from SKIP_SUBTREE_TYPES, handle bare nullable keywords - Remove template_string and concatenated_string from SKIP_SUBTREE_TYPES (template literals contain interpolated expressions with typed code) - Add FAST_NULLABLE_KEYWORDS check to fastStripNullable for behavioral parity with stripNullable on bare null/undefined/void/None/nil - Add explanatory comment on extractPendingAssignment scopeEnv guard * feat: add type resolution system and roadmap documentation --- AGENTS.md | 2 +- CLAUDE.md | 2 +- gitnexus/src/core/ingestion/call-processor.ts | 10 +-

In those cases, the resolver derives the loop variable type from the iterable's container type. + +```csharp +foreach (var user in users) { user.Save(); } + +// TypeScript +for (const user of users) { user.save(); } + +// Rust +for user in users { user.save(); } +``` + +This is handled by `resolveIterableElementType()` through a three-step cascade: + +1. **Declaration type nodes** + Uses raw type annotation nodes when available, including cases such as `User[]` or `List[User]`. + +2. **Scope environment string** + Uses `extractElementTypeFromString()` to parse a stored type string. + +3. **AST walk fallback** + Walks upward to enclosing declarations or parameters when needed. + +### Tier 0c: Pattern Binding + +Pattern-matching constructs may introduce a new variable or temporarily narrow an existing one. + +```csharp +if (obj is User user) { user.Save(); } + +// Java +if (obj instanceof User user) { user.save(); } + +// Rust +if let Some(user) = opt { user.save(); } + +// Python +match obj: + case User() as user: + user.save() +``` + +Binding behavior depends on the language: + +- **first-writer-wins** is used by default +- **position-indexed branch overrides** are used where branch-local narrowing must not leak between branches, most notably Kotlin + +### Tier 1: Initializer / Constructor Inference + +When there is no explicit annotation, the resolver can infer a type from the initializer. + +```typescript +const user = new User() + +// C# +var user = new User() + +// Kotlin +val user = User() + +// Go +user := User{} +ptr := &User{} +user2 := new(User) + +// Ruby +user = User.new +``` + +Some languages can identify constructor-like syntax directly. Others need validation through the `SymbolTable`, because syntax alone cannot always distinguish `User()` from `getUser()`. + +In those cases the system records an unverified binding candidate and later validates it against known class / struct symbols. + +### Tier 2: Assignment Chain Propagation + +Bindings can propagate through simple identifier assignments. + +```typescript +const user: User = getUser() +const alias = user +const other = alias +``` + +This is handled after the main walk through a single pass over pending assignments. + +This supports simple forward propagation, but there is no iterative fixpoint step. For example: + +```typescript +const b = a +const a: User = getUser() +``` + +will not resolve `b`. + +--- + +## Container Type Descriptors + +`CONTAINER_DESCRIPTORS` defines the type-parameter semantics for common containers. + +That allows the resolver to distinguish key-yielding methods from value-yielding methods instead of always assuming the last generic argument. + +```typescript +for (const key of map.keys()) { ... } // key → string +for (const val of map.values()) { ... } // val → User +``` + +Unknown containers fall back to heuristics, keeping the system conservative rather than fully semantic. + +### Examples of descriptor-driven behavior + +- `Map` / `Dictionary` / similar key-value containers +- `List` / `Array` / `Vec` / `Set` / similar single-element containers +- method-aware yield selection such as `.keys()`, `.values()`, `.keySet()`, `.Values` + +--- + +## Comment-Based Types + +For less strictly typed ecosystems, the resolver can fall back to documentation-based type information. + +Supported comment systems: + +- **JSDoc** for JavaScript / TypeScript +- **PHPDoc** for PHP +- **YARD** for Ruby + +These are used conservatively and only when AST-level type information is missing or insufficient. + +--- + +## SymbolTable Interaction + +Although the environment is built per file, it may consult the global `SymbolTable` in specific validation paths. + +This is important for languages where constructor-like syntax is ambiguous.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(type-resolution): Phase 7.1+7.2 foundation — ReturnTypeLookup, context object, pendingCallResults - Move extractReturnTypeName + helpers from call-processor.ts to type-extractors/shared.ts (breaks circular import risk: call-processor → type-env → type-extractors → call-processor) - Add SymbolTable.lookupFuzzyCallable(name) — lazy callable-only index, O(1) per call, invalidated on add(); avoids per-call .filter() on lookupFuzzy results - Add ReturnTypeLookup interface (conservative: undefined when 0 or 2+ callables match) - Add ForLoopExtractorContext interface — replaces 4 positional params with context object; update all 10 language extractor implementations (go, ts, py, jvm×2, cs, rs, rb, php, c-cpp) - Add PendingAssignment discriminated union (kind: 'copy' | 'callResult'); update PendingAssignmentExtractor in all 9 language extractors that implement it - Wire buildTypeEnv: build ReturnTypeLookup from optional symbolTable; split pendingAssignments into pendingCopies + pendingCallResults; add Tier 2b call-result propagation loop - Update call-processor.test.ts to import extractReturnTypeName from shared.ts * feat(type-resolution): Phase 7.3 — call_expression iterables in for-loop extractors (7 languages) Extends for-loop type extraction in all 7 typed-iteration languages to resolve element types when the iterable is a direct function call. **New capability**: `for (var u : getUsers())` in Java, `for u in get_users()` in Python, `for user in getUsers()` in TypeScript, etc. now resolve `u`/`user` to the callee's return element type via lookupRawReturnType + extractElementTypeFromString. Changes per language: - types.ts: extend ReturnTypeLookup with lookupRawReturnType (raw return string for container-type extraction); update ForLoopExtractorContext with returnTypeLookup field - type-env.ts: implement lookupRawReturnType on the concrete ReturnTypeLookup built in buildTypeEnv (same guards as lookupReturnType, no extractReturnTypeName) - go.ts: call_expression branch in range_clause — identifier func or selector_expression method; existing isChannelType guards updated - typescript.ts: identifier fn branch inside call_expression handler - python.ts: identifier fn branch inside call handler - jvm.ts (Java): method_invocation without object field in enhanced_for_statement - jvm.ts (Kotlin): simple_identifier callee branch in call_expression node - csharp.ts: identifier fn branch in invocation_expression handler - rust.ts: identifier func branch in call_expression handler (alongside existing field_expression/method-call path) All branches follow the same conservative pattern: lookupRawReturnType(callee) → extractElementTypeFromString → bind loop var * feat(type-resolution): Phase 7.4 — PHP \$this->property iterable via @var class property scan Adds Strategy C to PHP's extractForLoopBinding for the pattern: foreach (\$this->property as \$item) when Strategy A (resolveIterableElementType) and Strategy B (scopeEnv lookup) both fail to find the element type. Strategy C: when the iterable is a member_access_expression with object '$this', walk up the AST to the enclosing class_declaration, scan its declaration_list for a property_declaration whose variable_name matches the property, and extract the element type from: 1. PHPDoc @var annotation on a preceding comment sibling (/** @var User[] */) 2. PHP 7.4+ native type field (e.g. UserRepo \$repo — skips generic 'array') This eliminates the @param workaround that was previously required in the php-foreach-member-access fixture (which used @param User[] \$users on the method to populate the method's scopeEnv with a \$users binding). New helpers in php.ts: - PHPDOC_VAR_RE: regex for @var extraction - extractClassPropertyElementType: reads @var or native type from a property_declaration - findClassPropertyElementType: scans class body for a named property Tests added (type-env.test.ts): - PHP: resolves from @var User[] without @param workaround - PHP: conservative — no binding for unknown property - PHP: multi-class file — both classes resolve independently Fixture updated (php-foreach-member-access/App.php): - Removed the @param User[] \$users workaround from processMembers() - Test now validates the natural class-property-based resolution path * docs: mark Phase 7 complete in type-resolution-roadmap.md Records that 7A (call_expression iterables, 7 languages), 7B (PHP $this->property via @var scan), and 7C (ReturnTypeLookup + context object) are all shipped. Adds implementation notes and strikethroughs on resolved language-specific gaps. * fix(docs): update project references to feat-phase7-type-resolution in AGENTS.md and CLAUDE.md * feat(type-resolution): Phase 7.5 — PHP call_expression foreach + integration tests for 7 languages Add integration test coverage for Phase 7.3's call_expression iterable resolution across all 7 languages (Go, TypeScript, Python, Java, Kotlin, PHP, Rust). Each test creates a fixture with competing User/Repo classes that both define save(), then verifies for-loop iteration over a function call's return value resolves to the correct class. PHP was missing function_call_expression support in its for-loop extractor. Three changes fix this: - php.ts extractForLoopBinding: handle function_call_expression and member_call_expression iterables via returnTypeLookup - php.ts normalizePhpReturnType: preserve array notation (User[]) in SymbolTable so lookupRawReturnType returns useful container types - parse-worker.ts + parsing-processor.ts: upgrade uninformative AST return types (array, iterable) with PHPDoc @return annotations 35 new integration tests (5 per language), 2525 total tests passing. * fix(type-resolution): address PR #341 review findings — PHP asymmetry + dormant infrastructure docs - Replace normalizePhpType with extractElementTypeFromString in PHP call-expression foreach paths, aligning with all 6 other language extractors and preventing incorrect binding of bare non-container types like User - Add NOTE comments clarifying pendingCallResults Tier 2b is infrastructure-ready but no extractor populates it yet - Expand Go channel-type comments explaining why non-channel assumption is safe * fix(type-resolution): address verification review — docs accuracy + PHP fallback guard - Roadmap lines 86/100: correct pendingCallResults from "active" to "dormant infrastructure (Phase 9)" - type-resolution-system.md line 363: update to reflect Phase 7.3 loop inference is delivered - type-resolution-system.md line 409: clarify for-loop call-expression resolution (done) vs general assignment propagation (pending) -

Key changes: - SymbolTable: add `declaredType` field, `fieldByOwner` O(1) index, `lookupFieldByOwner()` method, P0 conditional callableIndex invalidation, P2 exclude Properties from globalIndex to prevent namespace pollution - tree-sitter queries: add `definition.property` for TypeScript, Java, Go - parse-worker: extract declared types for Property nodes via `extractPropertyDeclaredType()`, capture field-access receiver info - call-processor: add `resolveFieldAccessType()` helper and field-access branch in both sequential and worker receiver resolution paths - Integration tests: new field-types test suite verifying end-to-end `user.address.save() → Address#save` resolution * fix: Go tree-sitter query captures field_declaration not field_declaration_list Post-review fix: the Go struct field query incorrectly put @definition.property on field_declaration_list (the list container) instead of field_declaration (the individual field). Also removed unused `language` parameter from extractPropertyDeclaredType. * feat: expand field-type tests to 6 languages, fix Go ownerId and Kotlin navigation_expression - Add integration test fixtures for Java, C#, Go, Kotlin, PHP (alongside existing TS) - Fix Go: add type_declaration handling in findEnclosingClassId for struct fields (field_declaration → field_declaration_list → struct_type → type_spec → type_declaration) - Fix Kotlin: add navigation_expression handling in field-access resolution (Kotlin uses navigation_expression + navigation_suffix, not member_expression) - Add extractMemberAccessParts helper in call-processor for cross-language member access - All 24 field-type tests pass across 6 languages, 181 Go+Kotlin tests pass with no regressions * refactor: split HAS_METHOD into HAS_METHOD + HAS_PROPERTY edge types Property nodes now use HAS_PROPERTY edges instead of HAS_METHOD, giving the graph schema proper semantic separation between methods and fields. - HAS_METHOD: Method, Constructor, Function (when inside a class) - HAS_PROPERTY: Property nodes (class fields, struct fields, attributes) MRO processor only reads HAS_METHOD — properties correctly excluded from method resolution order. Impact analysis accepts both edge types. Updated 12 files: graph types, schema, tools docs, parse-worker, parsing-processor, call-processor, and 6 test files. * fix(test): update security test to expect 7 VALID_RELATION_TYPES (added HAS_PROPERTY) * test: add unit tests for Phase 8 SymbolTable features (39 tests, up from 19) Cover all new branches: declaredType metadata, Property exclusion from globalIndex, conditional callableIndex invalidation, lookupFieldByOwner (happy path + edge cases), lookupFuzzyCallable filtering, and clear() with fieldByOwner. Fixes branch coverage threshold (21.8% → 23%+). * feat: Phase 8B mixed field+method chain resolution, C++/Rust chain fixes Unify field and method chain resolution into a single `extractMixedChain` walker that handles interleaved patterns like `svc.getUser().address.save()`. Fix C++ chain calls (tree-sitter-cpp `field_expression` uses `argument` not `object`), Rust unit struct instantiation (`let svc = TypeName;`), and add stdlib passthrough for `unwrap()`/`clone()`/`expect()` in chain loops. Key changes: - Replace `receiverCallChain` + `receiverFieldAccess` with unified `receiverMixedChain: MixedChainStep[]` on ExtractedCall - Add `extractMixedChain` in utils.ts (handles both call_expression and field_expression nodes, including C++ `argument` field) - Add `TYPE_PRESERVING_METHODS` set for stdlib identity operations - Add C++ inline method double-indexing guard in parsing-processor.ts and parse-worker.ts - Add Rust unit struct recognition in type-extractors/rust.ts - Split field-types.test.ts into per-language test files - Add ts-mixed-chain fixture and integration tests - Resolve rust.test.ts todo: Option.unwrap().save() now works - Update roadmap: Phases 7+8 complete, Phase 9 is next * fix: Python declaredType extraction and sequential-path property registration - Move @definition.property capture from expression_statement to assignment node in Python queries so Strategy 1 childForFieldName('type') succeeds - Pass item.declaredType through ctx.symbols.add in sequential call-processor path, matching worker path behavior (fixes Ruby YARD declaredType drop) - Add Python chain resolution integration test (user.address.save → Address#save) - Update Rust/Python status in roadmap and system docs to reflect actual coverage * fix: Python/Ruby field type disambiguation and Rust chain test Three fixes from PR #354 third review: 1. Python typed_parameter name extraction: tree-sitter-python's typed_parameter uses positional children for the name, not a named field. TypeEnv and extractParameter now fall back to firstNamedChild. 2. Ruby/Python call-step field resolution: Ruby's AST uses `call` nodes for both property access and method calls. The chain walker now tries resolveFieldAccessType before resolveCallTarget for call steps, so attr_accessor properties resolve via declaredType. 3. Rust chain resolution test: added missing integration test asserting user.address.save() resolves to Address#save. Also splits C/C++ and TS/JS columns in type-resolution-system.md language matrix with footnotes for accuracy. 1062 resolver integration tests passing, 0 failures. * refactor: Phase 8 code review cleanup — extract walkMixedChain, fix MCP agent gaps - Extract duplicated chain resolution loop into shared walkMixedChain() helper, eliminating ~60 lines of copy-pasted code between sequential and worker paths - Add returnType to ResolveResult, removing redundant lookupFuzzy+find per chain step - Fix context() tool to include HAS_METHOD, HAS_PROPERTY, OVERRIDES in queries so agents can discover class members - Fix p.declaredType Cypher example (column doesn't exist) → p.description - Add HAS_METHOD, HAS_PROPERTY, OVERRIDES to schema resource - Document HAS_METHOD/HAS_PROPERTY in impact tool description - Delete dead code extractMemberAccessParts (superseded by extractMixedChain) - Replace any with SyntaxNode on extractPropertyDeclaredType - Add Rust deep-field-chain test (5 tests), Java mixed-chain (4), Go mixed-chain (4) - All 1075 tests pass (13 new, 0 regressions) * refactor: type SymbolDefinition.type as NodeLabel, add O(1) receiver index - Change SymbolDefinition.type from string to NodeLabel union (35 members) across symbol-table.ts, parse-worker.ts, parsing-processor.ts — compiler now enforces correctness at all comparison/assignment sites - Replace O(N*M) linear scan in lookupReceiverType with pre-built ReceiverTypeIndex (Map>) for O(1) lookups with proper ambiguity handling and file-level fallback - All 1075 tests pass, 0 regressions * fix: capture C++ pointer/ref fields, Kotlin data class props, PHP constructor promotion Add tree-sitter query patterns for three previously missed property declaration forms: C++ pointer/reference member fields (Address* addr; Address& ref;), Kotlin primary constructor val/var parameters (data class User(val name: String)), and PHP 8.0+ constructor property promotion (public Address $address). Fix "10 languages" off-by-one in docs (Ruby is single-level only, not deep chain). Update Python feature matrix cell from No* to Yes* after 31b95f0 fix. 11 new integration tests with per-language fixtures verify property capture, HAS_PROPERTY edge emission, and field-access chain resolution. --- gitnexus/src/core/graph/types.ts | 1 + gitnexus/src/core/ingestion/call-processor.ts | 305 +++++++++++------- gitnexus/src/core/ingestion/call-routing.ts | 22 ++

When walkMixedChain resolves a field access (e.g., user.address.save()), an ACCESSES edge with reason 'read' is emitted from the calling function to the Property node. Schema: ACCESSES added to RelationshipType, REL_TYPES, VALID_RELATION_TYPES, context queries, tools/resources descriptions. Excluded from default impact BFS to prevent traversal explosion. Implementation: resolveFieldAccessType now returns FieldResolution with fieldNodeId. walkMixedChain accepts optional onFieldResolved callback. makeAccessEmitter factory provides Set-based dedup per source node. Bug fix: Added Java 'field_access' to FIELD_ACCESS_NODE_TYPES — was missing, causing extractMixedChain to fail for Java member access. * feat: Phase 2 ACCESSES write edges — assignment detection across 12 languages Add tree-sitter query patterns for field write detection (obj.field = value) across all supported languages: TS/JS, Python, Java, Go, C++, C#, Rust, PHP, Ruby (setter syntax), Kotlin, Swift. Processing: Sequential path handles assignment captures inline. Worker path extracts ExtractedAssignment data for deferred resolution via new processAssignmentsFromExtracted function. Bug fix: Kotlin/Swift assignment queries used invalid navigation_expression wrapper — fixed to match actual directly_assignable_expression AST structure. Tests: Write access integration tests for TS, Java, Python, Go with dedicated fixtures. All use strict toBe() assertions. * test: add unit tests for call-routing, shared type extractors, and symbol-table branches Add 215 new unit tests across 3 files to increase branch coverage toward the 23% global threshold (was 21.49%): - call-routing.test.ts (49 tests): Ruby call routing — require/require_relative, include/extend/prepend heritage, attr_accessor properties with YARD types - shared-type-extractors.test.ts (108 tests): pure string functions — extractElementTypeFromString, stripNullable, extractReturnTypeName, methodToTypeArgPosition, getContainerDescriptor - symbol-table.test.ts (+29 tests): Property/fieldByOwner index, metadata spread branches, lazy callable index, lookupExactFull shape * fix: defer write-access resolution to fix Ruby cross-file property timing Ruby attr_accessor properties are registered during processCalls (not the parsing phase), so lookupFieldByOwner fails when service.rb is processed before models.rb. Fix by collecting pending write-access edges during the file loop and resolving them after all files are done. Also adds write-access integration tests and fixtures for 7 languages (C++, C#, JS, Kotlin, PHP, Ruby, Rust), Ruby compound assignment query, PHP static property write query, and Kotlin property type extraction. * fix: address PR #372 review — write-access constructor bindings parity and docs - Add verified constructor bindings fallback to write-access resolution in both sequential path (receiverIndex lookup) and worker path (constructorBindings param for processAssignmentsFromExtracted), closing the read/write ACCESSES edge asymmetry for factory-returned receivers - Clarify inner guard control flow comment in processCalls match loop - Document Go inc_statement/dec_statement gap in roadmap - Clarify PHP nullsafe write footnote (invalid syntax, not just untracked) - Update symbol-table tests for intentional fieldByOwner behavior change (Properties without declaredType now indexed for dynamic language write-access tracking) --- gitnexus/src/core/graph/types.ts | 3 +-

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: upgrade @ladybugdb/core to 0.15.2 and remove segfault workarounds The upstream fix (ladybug-nodejs#1) resolves the child QueryResult lifetime segfault, making .close() safe on all platforms. This removes 6 workaround sites: - Remove `dangerouslyIgnoreUnhandledErrors` from vitest config - Remove platform-conditional .close() guards in global-setup and test helper - Delete test/setup.ts (process._getActiveHandles unref hack) - Replace no-op cleanup in test-indexed-db.ts with real adapter close - Fix pool adapter closeOne() to properly close connections with shared Database refcount guard and orphaned connection handling in checkin() - Update segfault-related comments across the codebase Also bumps @ladybugdb/wasm-core to ^0.15.2 in gitnexus-web for consistency. Co-Authored-By: Claude Opus 4.6 (1M context) * fix: keep dangerouslyIgnoreUnhandledErrors for macOS N-API exit crash The N-API destructor ordering crash during worker fork exit on macOS is independent of the QueryResult lifetime fix in 0.15.2. Tests pass, but the exit triggers a crash. Keep the flag with an updated comment explaining the actual cause. Can be removed once LadybugDB fixes all destructor ordering issues upstream. Co-Authored-By: Claude Opus 4.6 (1M context) * ci: unify test run for single-pass coverage - Update `npm test` to run all tests (unit + integration + lbug-db) via `vitest run` instead of `vitest run test/unit` - Add `test:unit` script for running unit tests only - Remove `ci-integration.yml` — the per-file lbug-db process isolation is no longer needed with `dangerouslyIgnoreUnhandledErrors` and `fileParallelism: false` handling fork exit issues - Update `ci-unit-tests.yml` to run all tests with build + coverage - Simplify `ci.yml` gate (two jobs: quality + tests) - Simplify `ci-report.yml` (single coverage artifact, no merge step) * fix: update cli-commands test for renamed test:all → test:unit script * fix: set USERPROFILE in setup-skills test for Windows compatibility os.homedir() checks USERPROFILE on Windows, not HOME. * fix: add isolate: false to lbug-db project to prevent fork crashes On macOS, N-API destructors crash fork workers on exit. With isolate: true (default), vitest recycles the fork between files, triggering the crash after each file. After several crashes, the remaining lbug-db files never execute. isolate: false keeps all 8 lbug-db files in a single fork — the fork only exits once after all files complete, and that single exit crash is caught by dangerouslyIgnoreUnhandledErrors. * fix: add unique sequence.groupOrder to vitest projects Vitest v4 requires unique groupOrder when projects have different maxWorkers (lbug-db has fileParallelism: false → maxWorkers: 1). * fix: await async close() in global-setup and remove isolate: false global-setup.ts called conn.close() and db.close() without await — these return Promise in @ladybugdb/core 0.15.2. The setup function returned before the DB was fully closed, so vitest forks hit a stale file lock when opening the same DB path, crashing the lbug-db worker before any test ran. isolate: false caused native state corruption after 2-3 open/close cycles in the same fork (vitest-specific, not reproducible in plain Node.js). Without it, each file gets its own module scope and the N-API destructor crash at fork exit is caught by dangerouslyIgnoreUnhandledErrors. Also fixes fire-and-forget close() calls in the pool adapter — try/catch around an async close() never catches rejections; changed to .catch(() => {}) for proper unhandled-rejection prevention. Before: 0/8 lbug-db files ran on macOS CI (fork crash). After: 8/8 pass, 84 files, 3077 tests, zero errors. * fix: update project index references in AGENTS.md and CLAUDE.md to reflect correct symbol counts and relationships * feat: enhance lbug adapter with external database support and write operation validation * feat: create ci-tests workflow for comprehensive test coverage across platforms * ci: move PR report inline to ci.yml, delete ci-report.yml The old ci-report.yml used workflow_run which always runs code from the default branch (main). This meant the PR comment used main's stale report template that still referenced the old unit/integration split architecture — causing "Merge coverage reports" failures. Moving the report inline to ci.yml means it runs from the PR branch and uses the current report template. The report now shows: - per-platform status (Ubuntu/Windows/macOS columns) - unified test counts from the single vitest run - coverage with base branch (main) delta comparison - commit SHA for traceability Also removes the save-pr-meta job since the report no longer needs a separate workflow_run trigger. --------- Co-authored-by: Claude Opus 4.6 (1M context) Co-authored-by: Gergo Magyar --- .github/workflows/ci-integration.yml | 199 ------- .github/workflows/ci-report.yml | 522 ------------------ .../{ci-unit-tests.yml => ci-tests.yml} | 22 +- .github/workflows/ci.yml | 321 +++++++++-- AGENTS.md | 12 +- CLAUDE.md | 12 +- gitnexus-web/package.json | 2 +- gitnexus/package-lock.json | 71 ++- gitnexus/package.json | 6 +- gitnexus/src/core/lbug/lbug-adapter.ts | 3 + gitnexus/src/mcp/core/lbug-adapter.ts | 133 ++++- gitnexus/test/global-setup.ts | 10 +- gitnexus/test/helpers/test-indexed-db.ts | 38 +- .../integration/lbug-core-adapter.test.ts | 5 +- .../test/integration/local-backend.test.ts | 8 +- .../test/integration/setup-skills.test.ts | 3 + gitnexus/test/setup.ts | 29 - gitnexus/test/unit/cli-commands.test.ts | 2 +- gitnexus/test/unit/security.test.ts | 3 +- gitnexus/vitest.config.ts | 18 +- 20 files changed, 532 insertions(+), 887 deletions(-) delete mode 100644 .github/workflows/ci-integration.yml delete mode 100644 .github/workflows/ci-report.yml rename .github/workflows/{ci-unit-tests.yml => ci-tests.yml} (81%) delete mode 100644 gitnexus/test/setup.ts diff --git a/.github/workflows/ci-integration.yml b/.github/workflows/ci-integration.yml deleted file mode 100644 index 25ea4b8d4..000000000 --- a/.github/workflows/ci-integration.yml +++ /dev/null @@ -1,199 +0,0 @@ -name: Integration Tests - -on: - workflow_call: - inputs: - collect-coverage: - description: 'Whether to run the coverage collection job (only needed for PR reports)' - required: false - default: true - type: boolean - -jobs: - # ── Integration test matrix ───────────────────────────────────────── - # Each test-group runs on a SEPARATE runner per OS, giving full process - # isolation for the LadybugDB native C++ addon. - # 3 OS x 4 groups = 12 parallel jobs. - # - # Groups: - # lbug-db — 8 files using withTestLbugDB / lbug-adapter (native addon) - # Each file runs as its own `vitest run` invocation for full - # process isolation.

This enables `var user = getUser(); user.save()` to resolve at TypeEnv build time. Tier 2b now runs before Tier 2a copy-propagation, enabling mixed chains like `const user = getUser(); const alias = user; alias.save()`. Languages: TS, JS, Java, Kotlin, C#, Go, Rust, Python, PHP, Ruby, C++. Swift excluded. Each language gets a call-result-binding test fixture and integration tests. Conservative: only simple calls (no method calls with receivers), only when exactly one callable matches, first-writer-wins. --- gitnexus/src/core/ingestion/type-env.ts | 29 +++++---- .../core/ingestion/type-extractors/c-cpp.ts | 12 +++- .../core/ingestion/type-extractors/csharp.ts | 17 +++++ .../src/core/ingestion/type-extractors/go.ts | 14 ++++ .../src/core/ingestion/type-extractors/jvm.ts | 28 +++++++- .../src/core/ingestion/type-extractors/php.ts | 18 ++++-- .../core/ingestion/type-extractors/python.ts | 7 ++ .../core/ingestion/type-extractors/ruby.ts | 13 +++- .../core/ingestion/type-extractors/rust.ts | 7 ++ .../ingestion/type-extractors/typescript.ts | 10 +++ .../cpp-call-result-binding/app.cpp | 6 ++ .../cpp-call-result-binding/user.h | 14 ++++ .../csharp-call-result-binding/App.cs | 22 +++++++ .../go-call-result-binding/cmd/main.go | 12 ++++ .../go-call-result-binding/go.mod | 3 + .../go-call-result-binding/models/user.go | 9 +++ .../java-call-result-binding/App.java | 10 +++ .../java-call-result-binding/User.java | 11 ++++ .../js-call-result-binding/app.js | 6 ++ .../js-call-result-binding/models.js | 11 ++++ .../js-call-result-binding/service.js | 11 ++++ .../kotlin-call-result-binding/User.kt | 14 ++++ .../php-call-result-binding/App.php | 22 +++++++ .../python-call-result-binding/app.py | 5 ++ .../python-call-result-binding/models.py | 6 ++ .../python-call-result-binding/service.py | 4 ++ .../ruby-call-result-binding/app.rb | 15 +++++ .../rust-call-result-binding/src/main.rs | 7 ++ .../rust-call-result-binding/src/models.rs | 13 ++++ .../ts-call-result-binding/app.ts | 12 ++++ .../ts-call-result-binding/models.ts | 11 ++++ .../ts-call-result-binding/service.ts | 5 ++ .../test/integration/resolvers/cpp.test.ts | 23 +++++++ .../test/integration/resolvers/csharp.test.ts | 23 +++++++ .../test/integration/resolvers/go.test.ts | 23 +++++++ .../test/integration/resolvers/java.test.ts | 23 +++++++ .../test/integration/resolvers/kotlin.test.ts | 23 +++++++ .../test/integration/resolvers/php.test.ts | 23 +++++++ .../test/integration/resolvers/python.test.ts | 23 +++++++ .../test/integration/resolvers/ruby.test.ts | 23 +++++++ .../test/integration/resolvers/rust.test.ts | 23 +++++++ .../integration/resolvers/typescript.test.ts | 64 +++++++++++++++++++ type-resolution-roadmap.md | 16 +++-- type-resolution-system.md | 5 +- 44 files changed, 646 insertions(+), 30 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-call-result-binding/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-call-result-binding/user.h create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-call-result-binding/App.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/go-call-result-binding/cmd/main.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-call-result-binding/go.mod create mode 100644 gitnexus/test/fixtures/lang-resolution/go-call-result-binding/models/user.go create mode 100644 gitnexus/test/fixtures/lang-resolution/java-call-result-binding/App.java create mode 100644 gitnexus/test/fixtures/lang-resolution/java-call-result-binding/User.java create mode 100644 gitnexus/test/fixtures/lang-resolution/js-call-result-binding/app.js create mode 100644 gitnexus/test/fixtures/lang-resolution/js-call-result-binding/models.js create mode 100644 gitnexus/test/fixtures/lang-resolution/js-call-result-binding/service.js create mode 100644 gitnexus/test/fixtures/lang-resolution/kotlin-call-result-binding/User.kt create mode 100644 gitnexus/test/fixtures/lang-resolution/php-call-result-binding/App.php create mode 100644 gitnexus/test/fixtures/lang-resolution/python-call-result-binding/app.py create mode 100644 gitnexus/test/fixtures/lang-resolution/python-call-result-binding/models.py create mode 100644 gitnexus/test/fixtures/lang-resolution/python-call-result-binding/service.py create mode 100644 gitnexus/test/fixtures/lang-resolution/ruby-call-result-binding/app.rb create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-call-result-binding/src/main.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-call-result-binding/src/models.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/ts-call-result-binding/app.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/ts-call-result-binding/models.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/ts-call-result-binding/service.ts diff --git a/gitnexus/src/core/ingestion/type-env.ts b/gitnexus/src/core/ingestion/type-env.ts index 0e4a2edaa..9d95c6275 100644 --- a/gitnexus/src/core/ingestion/type-env.ts +++ b/gitnexus/src/core/ingestion/type-env.ts @@ -641,7 +641,21 @@ export const buildTypeEnv = ( walk(tree.rootNode, FILE_SCOPE);

Nullsafe writes (`$obj?->field = value`) are not tracked because this is invalid PHP syntax — null-safe member access on the left-hand side of assignment is a parse error. --- From e6b8edc1aceeeb581f58d7af6b5fbaa015facc9a Mon Sep 17 00:00:00 2001 From: Gergo Magyar Date: Thu, 19 Mar 2026 11:50:50 +0000 Subject: [PATCH 30/74] feat: Phase 9C unified fixpoint with field access and method-call-result binding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the sequential Tier 2b/2a propagation with a unified fixpoint loop that handles four binding kinds: callResult, copy, fieldAccess, and methodCallResult. The loop iterates until no new bindings are produced (max 10 iterations), enabling arbitrary-depth mixed chains: const user = getUser(); // callResult → User const addr = user.address; // fieldAccess → Address const city = addr.getCity(); // methodCallResult → City city.save(); // resolves to City#save Infrastructure: - PendingAssignment union extended with fieldAccess and methodCallResult - resolveFieldType helper: typeName → class nodeId → lookupFieldByOwner - resolveMethodReturnType helper: typeName → class nodeId → lookupFuzzyCallable filtered by ownerId - Fixpoint also resolves reverse-order copy chains that single-pass missed Languages: TS, JS, Java, Kotlin, C#, Go, Rust, Python, PHP, Ruby, C++. Each gets field access and/or method-call-with-receiver detection in extractPendingAssignment, plus method-chain-binding test fixtures. --- gitnexus/src/core/ingestion/type-env.ts | 121 +++++++++++++----- .../core/ingestion/type-extractors/c-cpp.ts | 18 ++- .../core/ingestion/type-extractors/csharp.ts | 27 +++- .../src/core/ingestion/type-extractors/go.ts | 35 ++++- .../src/core/ingestion/type-extractors/jvm.ts | 55 +++++++- .../src/core/ingestion/type-extractors/php.ts | 16 +++ .../core/ingestion/type-extractors/python.ts | 18 ++- .../core/ingestion/type-extractors/ruby.ts | 7 +- .../core/ingestion/type-extractors/rust.ts | 20 ++- .../core/ingestion/type-extractors/types.ts | 15 ++- .../ingestion/type-extractors/typescript.ts | 32 ++++- .../cpp-method-chain-binding/app.cpp | 8 ++ .../cpp-method-chain-binding/models.h | 26 ++++ .../csharp-method-chain-binding/App.cs | 29 +++++ .../go-method-chain-binding/cmd/main.go | 14 ++ .../go-method-chain-binding/go.mod | 3 + .../go-method-chain-binding/models/user.go | 21 +++ .../java-method-chain-binding/App.java | 12 ++ .../java-method-chain-binding/Models.java | 16 +++ .../kotlin-method-chain-binding/Models.kt | 18 +++ .../php-method-chain-binding/App.php | 28 ++++ .../python-method-chain-binding/app.py | 9 ++ .../python-method-chain-binding/models.py | 21 +++ .../ruby-method-chain-binding/app.rb | 31 +++++ .../rust-method-chain-binding/src/main.rs | 9 ++ .../rust-method-chain-binding/src/models.rs | 23 ++++ .../ts-method-chain-binding/app.ts | 8 ++ .../ts-method-chain-binding/models.ts | 31 +++++ .../ts-method-chain-binding/service.ts | 5 + .../test/integration/resolvers/cpp.test.ts | 23 ++++ .../test/integration/resolvers/csharp.test.ts | 23 ++++ .../test/integration/resolvers/go.test.ts | 23 ++++ .../test/integration/resolvers/java.test.ts | 23 ++++ .../test/integration/resolvers/kotlin.test.ts | 23 ++++ .../test/integration/resolvers/php.test.ts | 23 ++++ .../test/integration/resolvers/python.test.ts | 23 ++++ .../test/integration/resolvers/ruby.test.ts | 23 ++++ .../test/integration/resolvers/rust.test.ts | 23 ++++ .../integration/resolvers/typescript.test.ts | 31 +++++ gitnexus/test/unit/type-env.test.ts | 13 +- type-resolution-roadmap.md | 2 +- type-resolution-system.md | 8 +- 42 files changed, 871 insertions(+), 66 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-method-chain-binding/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-method-chain-binding/models.h create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-method-chain-binding/App.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/go-method-chain-binding/cmd/main.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-method-chain-binding/go.mod create mode 100644 gitnexus/test/fixtures/lang-resolution/go-method-chain-binding/models/user.go create mode 100644 gitnexus/test/fixtures/lang-resolution/java-method-chain-binding/App.java create mode 100644 gitnexus/test/fixtures/lang-resolution/java-method-chain-binding/Models.java create mode 100644 gitnexus/test/fixtures/lang-resolution/kotlin-method-chain-binding/Models.kt create mode 100644 gitnexus/test/fixtures/lang-resolution/php-method-chain-binding/App.php create mode 100644 gitnexus/test/fixtures/lang-resolution/python-method-chain-binding/app.py create mode 100644 gitnexus/test/fixtures/lang-resolution/python-method-chain-binding/models.py create mode 100644 gitnexus/test/fixtures/lang-resolution/ruby-method-chain-binding/app.rb create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-method-chain-binding/src/main.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-method-chain-binding/src/models.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/ts-method-chain-binding/app.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/ts-method-chain-binding/models.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/ts-method-chain-binding/service.ts diff --git a/gitnexus/src/core/ingestion/type-env.ts b/gitnexus/src/core/ingestion/type-env.ts index 9d95c6275..ce97f468c 100644 --- a/gitnexus/src/core/ingestion/type-env.ts +++ b/gitnexus/src/core/ingestion/type-env.ts @@ -2,7 +2,7 @@ import type { SyntaxNode } from './utils.js';

Mixed field+method chain resolution *(delivered)* +**Risks:** Performance of parent chain walking in fixpoint (bounded by `n_pending × depth × iterations`). Interface method ambiguity (mitigated by checking direct class first, parents on miss). -```typescript -svc.getUser().address.save() // call → field → call -user.getAddress().city.getName() // call → field → call -user.address.getCity().save() // field → call → call -user.unwrap().save() // stdlib passthrough → call -``` - -✅ `extractMixedChain` walks both call-expression and field-expression nodes in a single unified pass, producing `MixedChainStep[]`.

Swift excluded. Tier 2b now runs before Tier 2a copy-propagation, enabling mixed chains like `const user = getUser(); const alias = user; alias.save()`. +**Approach:** Add `{ kind: 'destructure', source, bindings: [{ varName, fieldName }] }` to `PendingAssignment`. In the fixpoint, when source's type resolves, look up each field via `lookupFieldByOwner` and bind each variable. -**Scope**: Phase 9A (simple call-result variable binding) and Phase 9C (unified fixpoint with field access + method-call-result binding) are fully implemented. Phase 9B (loop inference from assigned call results) remains open — it requires either a second walk pass after the fixpoint or treating for-loop variables as pending items, because for-loop bindings (Tier 0b) execute during `walk()` before the fixpoint runs, so fixpoint-resolved types can't retroactively update loop variable bindings. +Works without Phase 11A (direct fields only).

The target: -Delivered in Phase 7. +- Strong receiver-constrained call resolution across common language idioms +- Reliable handling of typed loops, constructors, and common patterns +- Return-type propagation for service/repository code +- Field/property knowledge for chained-member analysis +- Inheritance-aware lookups +- Conservative behavior under ambiguity +- Predictable performance during indexing -- loop inference works for identifier iterables and common call-expression iterables across 7 languages -- `ReturnTypeLookup` threads return-type knowledge into TypeEnv -- PHP class-level `@var` property typing for `$this->property` foreach - -### Milestone B — Structural Member Typing ✅ - -Delivered in Phase 8 + 8A + 8B. - -- field/property maps exist for class-like types across 9 languages -- deep chains resolve up to 3 levels (`user.address.city.getName()`) -- mixed field+method chains resolve interleaved patterns (`svc.getUser().address.save()`) -- stdlib passthroughs (`unwrap`, `clone`, etc.) are type-preserving in chains -- C++ and Rust chain call resolution fixed (field_expression argument, unit struct) - -### Milestone C — Static-Analysis Foundation ← **next** - -Success looks like: - -- return-type-aware variable binding is a first-class part of environment construction -- chains, loops, and assignments share a coherent propagation model -- downstream graph features can rely on more than local receiver heuristics - ---- - -## Open Questions for Future Design - -These should be resolved before or during implementation of the later phases. - -1. **Where should field-type metadata live?** - ✅ Resolved: in `SymbolTable` via the `fieldByOwner` index, keyed by `ownerNodeId\0fieldName`. Properties live alongside other symbols but are excluded from `globalIndex` to prevent namespace pollution. - -2. **How should ambiguity be represented?** - Is `undefined` sufficient, or do later phases need a richer "known ambiguous" state? - -3. **How much receiver context should return-type inference require?** - Some methods only become meaningful once the receiver type is already partially known. - -4. **How much branch sensitivity is worth the complexity?** - Some narrowing gives clear value; full control-flow typing likely does not. - -5. **Should field typing and chain typing be one phase or two?** - ✅ Resolved: delivered as Phase 8 (single-level) + Phase 8A (deep chains) in the same branch, with separate test suites per language. Incremental delivery within one phase worked well. +That supports: better call graphs, more accurate impact analysis, stronger AI context assembly, more trustworthy graph traversal. --- ## Summary -Phases 7 and 8 (including 8A and 8B) are **complete**. The type system now handles: +**Complete:** Phases 7, 8, 9, 9C — explicit types, constructor inference, loop inference, field/property resolution, deep chains, mixed chains, stdlib passthroughs, comment-based types, unified fixpoint with 4 binding kinds, arbitrary-depth chain propagation across 11 languages. -- ✅ explicit type annotations and parameters across 13 languages -- ✅ initializer/constructor inference with SymbolTable validation -- ✅ loop element inference including call-expression iterables (7 languages) -- ✅ field/property type resolution with deep chains (up to 3 levels, 10 languages) -- ✅ mixed field+method chains (`svc.getUser().address.save()`) -- ✅ type-preserving stdlib passthroughs (`unwrap`, `clone`, `expect`, etc.) -- ✅ comment-based types (JSDoc, PHPDoc, YARD) +**Next:** Phase 10 (loop-fixpoint bridge) → Phase 11 (MRO + this/self + Go + Swift) → Phase 12 (destructuring) → Phase 13 (branch narrowing) → Phase 14 (cross-file propagation). -**Phase 9 and 9C are complete**: return-type-aware inference is now a first-class input to `TypeEnv`. Phase 9 activated simple call-result binding. Phase 9C replaced the sequential Tier 2b/2a with a unified fixpoint loop handling four binding kinds (`callResult`, `copy`, `fieldAccess`, `methodCallResult`) that iterates until no new bindings are produced. This enables arbitrary-depth mixed chains like `getUser() → .address → .getCity() → city.save()` across all 11 languages. **Next steps**: Phase 9B (loop inference from assigned call results). - -That path preserves the current strengths of the system while moving GitNexus the final step toward a robust, production-grade static-analysis foundation. +Each phase is independently deliverable (except Phase 14 which depends on 10–13 being stable). Swift parity is threaded incrementally through Phases 10–13.

Impact enrichment queries (Promise.all → sequential await) The impact() method ran 3 enrichment queries concurrently via Promise.all against the same LadybugDB connection pool. On arm64 macOS, concurrent native DB access triggers SIGSEGV. Changed to sequential await. Also caps IN-clause to 100 IDs to prevent oversized queries. (#285, #290, #292) 2. Silence stdout during query execution silenceStdout()/restoreStdout() only wrapped createConnection() and initLbug(). Now also wraps executeQuery() and executeParameterized() to prevent native stdout writes from corrupting the MCP stdio stream during all DB operations. (#285) 3.

Narrow Go /cmd/ entry-point detection to only match /main.go - Fix Rust scoped grouped imports (use crate::models::{User, Repo}) resolution - Filter PHP use function/use const from class-type namedImportMap bindings Improvements (P1): - Add C# resolveStandard fallback when .csproj discovery fails - Change preprocessImportPath return type to string | null with caller guards - Add Q_SIGNALS/Q_SLOTS (standard plural Qt macros) - Fix stale "11 supported languages" comment → 13 API simplification (P2): - Replace buildImportResolvers() factory with const importResolvers table - Move configs onto ResolveCtx (extends ImportResolutionContext) - Eliminate tsconfigPaths parameter threading through 6 non-TS resolvers - Split utils.ts (1,476 lines) into ast-helpers.ts + call-analysis.ts + utils.ts - Consolidate findChild/findChildByType into single source of truth - Match multi-file import bindings to files by basename for namedImportMap Cleanup (P3): - EMPTY_INDEX returns shared frozen empty array instead of allocating per call - Type appendKotlinWildcard parameter as SyntaxNode instead of any - Document call-routing validation requirement on CallRouter type Tests: - Add unit tests for preprocessImportPath (13 tests) - Add integration tests: Rust scoped multi-file, PHP use function/const, C# without .csproj, Go cmd/ helper scoring (14 tests, 4 fixtures) All 3579 tests pass. --- gitnexus/src/config/supported-languages.ts | 2 +- gitnexus/src/core/ingestion/ast-helpers.ts | 710 ++++++++++ gitnexus/src/core/ingestion/call-analysis.ts | 539 +++++++ gitnexus/src/core/ingestion/call-routing.ts | 6 + .../src/core/ingestion/entry-point-scoring.ts | 2 +- .../src/core/ingestion/framework-detection.ts | 6 +- .../src/core/ingestion/import-processor.ts | 57 +- .../src/core/ingestion/import-resolution.ts | 134 +- .../ingestion/named-binding-extraction.ts | 7 + gitnexus/src/core/ingestion/resolvers/jvm.ts | 3 +- .../src/core/ingestion/resolvers/utils.ts | 4 +- .../core/ingestion/type-extractors/csharp.ts | 9 +- .../src/core/ingestion/type-extractors/go.ts | 2 +- .../core/ingestion/type-extractors/index.ts | 1 -
