charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces a shared 3-tier resolveSymbol function used by both heritage-processor and call-processor: 1. Same-file (lookupExactFull — authoritative) 2. Import-scoped (filtered by ImportMap — high confidence) 3.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add Go struct embedding detection (anonymous fields → EXTENDS edges) via new tree-sitter heritage query with named-field filtering in both parse-worker and heritage-processor paths. Implement PackageMap optimization for Go cross-package resolution: replace O(N) file-level ImportMap expansion with directory-level suffix matching (Tier 2b in symbol resolver). Graph IMPORTS edges are preserved via addImportGraphEdge split. Remove overly broad @definition.type from GO_QUERIES that was double-matching structs/interfaces as TypeAlias nodes, breaking Tier 3 unique-global resolution. Add Go fixture (go-pkg) with Admin→User embedding, cross-package calls, and 7 integration tests covering structs, functions, imports, calls, and heritage edges. --- gitnexus/src/core/ingestion/call-processor.ts | 18 ++- .../src/core/ingestion/heritage-processor.ts | 42 ++++--- .../src/core/ingestion/import-processor.ts | 106 ++++++++++++++--- gitnexus/src/core/ingestion/pipeline.ts | 17 +-- .../src/core/ingestion/symbol-resolver.ts | 21 +++- .../src/core/ingestion/tree-sitter-queries.ts | 10 +- .../core/ingestion/workers/parse-worker.ts | 21 +++- .../lang-resolution/go-pkg/cmd/main.go | 13 +++ .../fixtures/lang-resolution/go-pkg/go.mod | 3 + .../go-pkg/internal/auth/service.go | 12 ++ .../go-pkg/internal/models/admin.go | 10 ++ .../go-pkg/internal/models/repository.go | 6 + .../go-pkg/internal/models/user.go | 10 ++ .../test/integration/lang-resolution.test.ts | 63 +++++++++++ gitnexus/test/unit/call-processor.test.ts | 2 +- gitnexus/test/unit/heritage-processor.test.ts | 2 +- gitnexus/test/unit/symbol-resolver.test.ts | 107 +++++++++++++++++- 17 files changed, 405 insertions(+), 58 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/go-pkg/cmd/main.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-pkg/go.mod create mode 100644 gitnexus/test/fixtures/lang-resolution/go-pkg/internal/auth/service.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-pkg/internal/models/admin.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-pkg/internal/models/repository.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-pkg/internal/models/user.go diff --git a/gitnexus/src/core/ingestion/call-processor.ts b/gitnexus/src/core/ingestion/call-processor.ts index 6784b29df4..25c4137d7f 100644 --- a/gitnexus/src/core/ingestion/call-processor.ts +++ b/gitnexus/src/core/ingestion/call-processor.ts @@ -1,7 +1,7 @@ import { KnowledgeGraph } from '../graph/types.js';

edges, method calls, MRO overrides - Add ambiguous symbol resolution tests for all 9 languages verifying correct disambiguation via import chains - Split monolithic lang-resolution.test.ts (1080 lines) into 9 per-language files under test/integration/resolvers/ with shared helpers --- .../src/core/ingestion/import-processor.ts | 1127 +++--------------

Gergo Magyar Date: Wed, 11 Mar 2026 18:29:50 +0000 Subject: [PATCH 12/34] =?UTF-8?q?feat:=20harden=20CALLS-edge=20resolution?= =?UTF-8?q?=20=E2=80=94=20Phase=200=20validation?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix same-file confidence (0.85 → 0.95) to correctly outrank import-scoped (0.9) - Fix Tier 1 overload preservation: use globalIndex filter instead of fileIndex lookup - Add callable-kind guard: refuse CALLS edges to Interface and Enum symbols - Fix Kotlin countCallArguments: handle call_suffix → value_arguments nesting - Fix Kotlin extractFunctionName: add simple_identifier to fallback search - Strictly type findParameterList and countCallArguments (remove all `any`) - Add arity-based call resolution integration tests for 9 languages - Add unit regression tests for Interface/Enum CALLS refusal --- AGENTS.md | 2 +- CLAUDE.md | 2 +- gitnexus/src/core/ingestion/call-processor.ts | 142 ++++++++++++++----

and ownerId to symbol table (Phase 1) Add inferCallForm() and extractReceiverName() to distinguish free/member/constructor calls at the AST level across all 9 languages. Add ownerId field to SymbolDefinition linking Method/Constructor/Property to their owning class. Includes 36 unit tests and member-call integration tests for all 9 languages (132 tests, 0 failures). --- gitnexus/src/core/ingestion/call-processor.ts | 10 +- .../src/core/ingestion/parsing-processor.ts | 27 +- gitnexus/src/core/ingestion/symbol-table.ts | 7 +- gitnexus/src/core/ingestion/utils.ts | 149 +++++++ .../core/ingestion/workers/parse-worker.ts | 48 +- .../lang-resolution/cpp-member-calls/app.cpp | 6 + .../lang-resolution/cpp-member-calls/user.h | 6 + .../csharp-member-calls/MemberCallProj.csproj | 5 + .../csharp-member-calls/Models/User.cs | 9 + .../Services/UserService.cs | 12 + .../go-member-calls/cmd/main.go | 8 + .../lang-resolution/go-member-calls/go.mod | 3 + .../go-member-calls/models/user.go | 7 + .../java-member-calls/models/User.java | 7 + .../services/UserService.java | 10 + .../kotlin-member-calls/models/User.kt | 7 + .../services/UserService.kt | 10 + .../php-member-calls/app/Models/User.php | 11 + .../app/Services/UserService.php | 14 + .../php-member-calls/composer.json | 7 + .../python-member-calls/app.py | 5 + .../python-member-calls/user.py | 3 + .../rust-member-calls/src/main.rs | 9 + .../rust-member-calls/src/user.rs | 7 + .../typescript-member-calls/src/app.ts | 6 + .../typescript-member-calls/src/user.ts | 5 + .../test/integration/resolvers/cpp.test.ts | 34 ++ .../test/integration/resolvers/csharp.test.ts | 34 ++ .../test/integration/resolvers/go.test.ts | 32 ++ .../test/integration/resolvers/java.test.ts | 34 ++ .../test/integration/resolvers/kotlin.test.ts | 29 ++ .../test/integration/resolvers/php.test.ts | 34 ++ .../test/integration/resolvers/python.test.ts | 29 ++ .../test/integration/resolvers/rust.test.ts | 33 ++ .../integration/resolvers/typescript.test.ts | 34 ++ gitnexus/test/unit/call-form.test.ts | 419 ++++++++++++++++++ 36 files changed, 1082 insertions(+), 28 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-member-calls/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-member-calls/user.h create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-member-calls/MemberCallProj.csproj create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-member-calls/Models/User.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-member-calls/Services/UserService.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/go-member-calls/cmd/main.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-member-calls/go.mod create mode 100644 gitnexus/test/fixtures/lang-resolution/go-member-calls/models/user.go create mode 100644 gitnexus/test/fixtures/lang-resolution/java-member-calls/models/User.java create mode 100644 gitnexus/test/fixtures/lang-resolution/java-member-calls/services/UserService.java create mode 100644 gitnexus/test/fixtures/lang-resolution/kotlin-member-calls/models/User.kt create mode 100644 gitnexus/test/fixtures/lang-resolution/kotlin-member-calls/services/UserService.kt create mode 100644 gitnexus/test/fixtures/lang-resolution/php-member-calls/app/Models/User.php create mode 100644 gitnexus/test/fixtures/lang-resolution/php-member-calls/app/Services/UserService.php create mode 100644 gitnexus/test/fixtures/lang-resolution/php-member-calls/composer.json create mode 100644 gitnexus/test/fixtures/lang-resolution/python-member-calls/app.py create mode 100644 gitnexus/test/fixtures/lang-resolution/python-member-calls/user.py create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-member-calls/src/main.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-member-calls/src/user.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/typescript-member-calls/src/app.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/typescript-member-calls/src/user.ts create mode 100644 gitnexus/test/unit/call-form.test.ts diff --git a/gitnexus/src/core/ingestion/call-processor.ts b/gitnexus/src/core/ingestion/call-processor.ts index 0b73d0d3c1..0e98def699 100644 --- a/gitnexus/src/core/ingestion/call-processor.ts +++ b/gitnexus/src/core/ingestion/call-processor.ts @@ -7,7 +7,15 @@ import Parser from 'tree-sitter';

Queries: new_expression (C++), object_creation_expression (PHP), composite_literal (Go), struct_expression (Rust), primary constructor and implicit_object_creation_expression (C#). Relaxes global tier in collectTieredCandidates to pass all candidates through filterCallableCandidates, allowing kind/arity narrowing to disambiguate at lower confidence. --- gitnexus/src/core/ingestion/call-processor.ts | 47 ++++++--- .../src/core/ingestion/tree-sitter-queries.ts | 33 +++++++ gitnexus/src/core/ingestion/utils.ts | 12 ++- .../cpp-constructor-calls/app.cpp | 6 ++ .../cpp-constructor-calls/user.h | 10 ++ .../csharp-primary-ctors/App.cs | 15 +++ .../csharp-primary-ctors/Models/Person.cs | 4 + .../csharp-primary-ctors/Models/User.cs | 10 ++ .../lang-resolution/go-struct-literals/app.go | 6 ++ .../go-struct-literals/user.go | 9 ++ .../java-constructor-calls/App.java | 8 ++ .../java-constructor-calls/models/User.java | 13 +++ .../php-constructor-calls/Models/User.php | 15 +++ .../php-constructor-calls/app.php | 8 ++ .../rust-struct-literals/app.rs | 7 ++ .../rust-struct-literals/user.rs | 9 ++ .../typescript-constructor-calls/src/app.ts | 6 ++ .../typescript-constructor-calls/src/user.ts | 9 ++ .../test/integration/resolvers/cpp.test.ts | 36 +++++++ .../test/integration/resolvers/csharp.test.ts | 78 ++++++++++++++- .../test/integration/resolvers/go.test.ts | 47 ++++++++- .../test/integration/resolvers/java.test.ts | 38 +++++++ .../test/integration/resolvers/php.test.ts | 38 +++++++ .../test/integration/resolvers/rust.test.ts | 41 ++++++++ .../integration/resolvers/typescript.test.ts | 37 +++++++ gitnexus/test/unit/call-processor.test.ts | 99 +++++++++++++++++++ 26 files changed, 617 insertions(+), 24 deletions(-) create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-constructor-calls/app.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-constructor-calls/user.h create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-primary-ctors/App.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-primary-ctors/Models/Person.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-primary-ctors/Models/User.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/go-struct-literals/app.go create mode 100644 gitnexus/test/fixtures/lang-resolution/go-struct-literals/user.go create mode 100644 gitnexus/test/fixtures/lang-resolution/java-constructor-calls/App.java create mode 100644 gitnexus/test/fixtures/lang-resolution/java-constructor-calls/models/User.java create mode 100644 gitnexus/test/fixtures/lang-resolution/php-constructor-calls/Models/User.php create mode 100644 gitnexus/test/fixtures/lang-resolution/php-constructor-calls/app.php create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-struct-literals/app.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-struct-literals/user.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/typescript-constructor-calls/src/app.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/typescript-constructor-calls/src/user.ts diff --git a/gitnexus/src/core/ingestion/call-processor.ts b/gitnexus/src/core/ingestion/call-processor.ts index 0e98def699..1118e99ffb 100644 --- a/gitnexus/src/core/ingestion/call-processor.ts +++ b/gitnexus/src/core/ingestion/call-processor.ts @@ -7,7 +7,7 @@ import Parser from 'tree-sitter';

Key changes: - call-processor: build per-file TypeEnv, pass receiverTypeName to resolveCallTarget - parse-worker: extract receiverTypeName from TypeEnv in worker thread - resolveCallTarget: new step D filters by ownerId matching receiver type - utils: extractReceiverName supports C++ field_expression (argument field) - utils: findEnclosingClassId extracts Go method receiver types - type-env: handle Go qualified_type, Kotlin user_type/variable_declaration - parse-worker + parsing-processor: Function added to needsOwner for Kotlin/Rust/Python class methods captured as Function nodes Integration tests added for receiver-constrained resolution across all 9 languages: TypeScript, Java, Python, Go, Rust, C++, C#, Kotlin, PHP. --- gitnexus/src/core/ingestion/call-processor.ts | 32 +-

charset=UTF-8 Content-Transfer-Encoding: 8bit Address all 4 PR #238 review items: 1. Remove redundant lookupFuzzy in processRoutesFromExtracted 2. Add NamedImportMap for TS/Python symbol-level import tracking (Tier 2a) 3. Make TypeEnv scope-aware (Map>) to fix non-deterministic receiver resolution across functions 4. Broaden extractMethodSignature: Go/Rust/C++ return types, variadic detection for Go/Java/Python/C++/Kotlin/TypeScript rest params Discovered and fixed: TS rest params (...args) were not detected as variadic — added rest_pattern detection inside required_parameter nodes.

Add integration test fixtures and tests for all 5 languages (Python alias extraction already worked, just needed the test). Each test verifies: class detection, member call resolution through aliases to correct target files, and IMPORTS edge emission. --- .../src/core/ingestion/import-processor.ts | 75 ++++++++++++ .../core/ingestion/workers/parse-worker.ts | 114 ++++++++++++++++++ .../csharp-alias-imports/CsharpAlias.csproj | 6 + .../csharp-alias-imports/Models/Repo.cs | 9 ++ .../csharp-alias-imports/Models/User.cs | 9 ++ .../csharp-alias-imports/Services/Main.cs | 16 +++ .../kotlin-alias-imports/app/App.kt | 11 ++ .../kotlin-alias-imports/models/Models.kt | 9 ++ .../php-alias-imports/app/Models/Repo.php | 14 +++ .../php-alias-imports/app/Models/User.php | 14 +++ .../php-alias-imports/app/Services/Main.php | 14 +++ .../php-alias-imports/composer.json | 7 ++ .../python-alias-imports/app.py | 7 ++ .../python-alias-imports/models.py | 13 ++ .../rust-alias-imports/src/main.rs | 11 ++ .../rust-alias-imports/src/models.rs | 19 +++ .../test/integration/resolvers/csharp.test.ts | 44 +++++++ .../test/integration/resolvers/kotlin.test.ts | 36 ++++++ .../test/integration/resolvers/php.test.ts | 46 +++++++ .../test/integration/resolvers/python.test.ts | 39 ++++++ .../test/integration/resolvers/rust.test.ts | 46 +++++++ 21 files changed, 559 insertions(+) create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-alias-imports/CsharpAlias.csproj create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-alias-imports/Models/Repo.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-alias-imports/Models/User.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/csharp-alias-imports/Services/Main.cs create mode 100644 gitnexus/test/fixtures/lang-resolution/kotlin-alias-imports/app/App.kt create mode 100644 gitnexus/test/fixtures/lang-resolution/kotlin-alias-imports/models/Models.kt create mode 100644 gitnexus/test/fixtures/lang-resolution/php-alias-imports/app/Models/Repo.php create mode 100644 gitnexus/test/fixtures/lang-resolution/php-alias-imports/app/Models/User.php create mode 100644 gitnexus/test/fixtures/lang-resolution/php-alias-imports/app/Services/Main.php create mode 100644 gitnexus/test/fixtures/lang-resolution/php-alias-imports/composer.json create mode 100644 gitnexus/test/fixtures/lang-resolution/python-alias-imports/app.py create mode 100644 gitnexus/test/fixtures/lang-resolution/python-alias-imports/models.py create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-alias-imports/src/main.rs create mode 100644 gitnexus/test/fixtures/lang-resolution/rust-alias-imports/src/models.rs diff --git a/gitnexus/src/core/ingestion/import-processor.ts b/gitnexus/src/core/ingestion/import-processor.ts index 53e1de8e5b..1ae373159c 100644 --- a/gitnexus/src/core/ingestion/import-processor.ts +++ b/gitnexus/src/core/ingestion/import-processor.ts @@ -92,6 +92,81 @@ function extractNamedBindingsFromAST( return bindings.length > 0 ? bindings : undefined;

This ensures compile-time safety for language dispatch and eliminates dead `language === 'tsx'` checks (tsx maps to TypeScript in the enum). --- gitnexus/src/core/graph/types.ts | 4 +- .../src/core/ingestion/entry-point-scoring.ts | 31 ++++++------- .../src/core/ingestion/export-detection.ts | 27 +++++------ .../src/core/ingestion/framework-detection.ts | 18 ++++---- .../src/core/ingestion/heritage-processor.ts | 5 ++- .../src/core/ingestion/import-processor.ts | 16 +++---- gitnexus/src/core/ingestion/mro-processor.ts | 22 ++++----- .../src/core/ingestion/process-processor.ts | 3 +- gitnexus/src/core/ingestion/type-env.ts | 45 ++++++++++--------- .../core/ingestion/workers/parse-worker.ts | 18 ++++---- 10 files changed, 100 insertions(+), 89 deletions(-) diff --git a/gitnexus/src/core/graph/types.ts b/gitnexus/src/core/graph/types.ts index 42b32cfd04..aa9b245384 100644 --- a/gitnexus/src/core/graph/types.ts +++ b/gitnexus/src/core/graph/types.ts @@ -35,12 +35,14 @@ export type NodeLabel = | 'Template';

tier-ordering bug, re-export chains, PHP grouped imports, Java named imports - Fix collectTieredCandidates tier-ordering: same-file now checked before named bindings, preventing imports from shadowing local definitions (matches resolveSymbolInternal priority order) - Add re-export chain resolution for TypeScript/JavaScript barrel files: export { X } from './base' and export type { X } from './base' now followed up to 5 hops through NamedImportMap - Fix PHP grouped import alias extraction: use App\Models\{User, Repo as R} now correctly handled in both parse-worker and import-processor - Add Java NamedImportMap support: import com.example.models.User now records User as a named binding for precise disambiguation - Add 16 new integration tests across TypeScript, PHP, and Java resolvers (220

00:00:00 2001 From: Gergo Magyar Date: Thu, 12 Mar 2026 09:53:01 +0000 Subject: [PATCH 22/34] refactor: consolidate alias extraction + add variadic/constructor/shadow integration tests - Extract shared named-binding-extraction.ts from duplicate logic in import-processor.ts and parse-worker.ts (net -200 lines) - Deduplicate appendKotlinWildcard (now imported from resolvers/index.ts) - Add integration tests: constructor calls (Kotlin, Python), variadic resolution (Go, Java, C#, C++, Kotlin), re-export chains (Python), local definition shadowing (Python, Go) - Add TODO(stack-graph) for TypeEnv scope key collision - 225 integration tests passing (was 223) --- .../src/core/ingestion/import-processor.ts | 193 +----------- .../ingestion/named-binding-extraction.ts | 279
