feat: same-arity overload disambiguation via type-hash suffix (#651) (#658)
* feat: same-arity overload disambiguation via type-hash suffix (#651)

Add ~type1,type2 suffix to Method/Constructor node IDs when same-arity
overloads with different parameter types exist in the same class. Also add
$const suffix for C++ const-qualified method overloads via new isConst field.

Key changes:
- typeTagForId() detects same-arity collisions and appends ~typeTag
- constTagForId() detects const/non-const collisions and appends $const
- TS/JS excluded from type-hashing (overload signatures collapse to impl body)
- Sequential findEnclosingFunction fixed: falls through on ambiguous same-class
  candidates instead of picking first; fallback path includes typeTag + constTag
- Per-call-site integration tests across Java, C#, Kotlin, C++, TypeScript
- Cross-file + chain resolution tests for all 5 languages
- C++ isConst extraction via tree-sitter type_qualifier in function_declarator

1710 integration + 18 unit tests pass.

* fix: preserve generic/template args in type-hash, perf + type safety fixes

- Add rawType field to ParameterInfo preserving full type text (vector<int>)
  while type stays simplified (vector). typeTagForId uses rawType for tags.
- Populate rawType in all 11 language method extractors
- Add buildCollisionGroups() to pre-group methods by name#arity (O(N) once
  per class instead of O(N) per method call)
- Cache method extraction in call-processor findEnclosingFunction fallback
- Fix null guards on getLanguageFromFilename in all findEnclosing paths
- Tighten SKIP_TYPE_HASH_LANGUAGES to ReadonlySet<SupportedLanguages>
- Document ID stability invariant on first overload introduction
- C++ integration tests: template overloads (vector<int> vs vector<string>),
  cross-file template + chain resolution, out-of-class method definitions

1718 integration + 20 unit tests pass.

* fix: add rawType to method-extraction unit test assertions

All 26 parameter .toEqual() assertions in method-extraction.test.ts
needed the new rawType field added to match ParameterInfo schema change.

* perf: cache tempMap/groups per class, consolidate extractFromNode

- Cache derived method map + collision groups per classNode.id in
  parsing-processor (avoids rebuild per method in same class)
- Replace per-call extractFromNode with cached class extraction +
  funcName:line lookup in call-processor fallback (avoids AST walk
  per call site)
- Remove dead clearEnclosingFunctionCache export, fix JSDoc

* test: add sequential-path integration test for same-arity overloads

Add skipWorkers option to PipelineOptions to force sequential parsing.
New test suite verifies type-hash disambiguation produces identical
results through the sequential path (parsing-processor + call-processor
findEnclosingFunction) as the worker path.

feat: MethodExtractor configs for Python, PHP, Swift, Dart, Rust, Ruby (#624)
* feat: MethodExtractor configs for Python, PHP, Swift, Dart, Rust, Ruby with exhaustive integration tests

Add per-language MethodExtractionConfig for all remaining tree-sitter languages
(RFC #568 PR 2). Each config follows the established createMethodExtractor()
factory pattern — no new types, no parse-worker changes.

Configs:
- Python: @abstractmethod, @staticmethod/@classmethod, *args/**kwargs, type hints, _/__ visibility
- PHP: abstract/final/static keywords, PHP 8 #[] attributes, __construct/__destruct
- Swift: 5-level visibility, protocol-as-abstract, static/class methods, @ attributes
- Dart: _ convention visibility, abstract (no body), method_signature unwrapping
- Rust: pub visibility, &self receiver, trait_item + impl_item, #[] attributes
- Ruby: positional visibility via sibling-walk, singleton_method as static

Integration fixtures (18 directories) covering 3 resolution patterns:
- Method enrichment: parameterTypes, isAbstract, isFinal, annotations on graph nodes
- Overload dispatch: arity-based CALLS resolution via parameterTypes
- Abstract dispatch: abstract/concrete method distinction (Python, PHP, Rust, Swift)

Go deferred — requires factory changes for receiver-based method extraction.

Closes #571

* fix: address code review findings across 6 MethodExtractor configs

Fix all actionable items from the PR #624 deep-dive review:

Dart (critical — fixes 6 CI failures):
- isDartStatic: check children first, siblings as fallback
- isDartAbstract: handle declaration nodes for abstract methods
- extractSingleParam: detect required keyword as sibling token
- Add declaration to methodNodeTypes, mixin_declaration to typeDeclarationNodes
- Add member call query for variable assignments in tree-sitter-queries

Python:
- hasDecorator now matches dotted paths (e.g. @abc.abstractmethod)
- Fix version comment from ^0.23.6 to 0.23.4

PHP:
- Add enum_declaration to typeDeclarationNodes (PHP 8.1+)
- Add version comment for 0.23.12

Swift:
- Add isOverride using hasKeyword/hasModifier pattern

Rust:
- Fix version comment from ^0.23.2 to 0.23.1

Also: identifier fallback in generic.ts for mixin owner names,
Dart integration test label fix (Method vs Function), version
comment for tree-sitter-dart 1.0.0.

* fix: Dart extension_declaration and Ruby module_function support

Dart:
- Add extension_declaration to typeDeclarationNodes and extension_body
  to bodyNodeTypes — extension methods are now extracted into the graph
- Add extension_declaration and mixin_declaration to CLASS_CONTAINER_TYPES
  for HAS_METHOD edge resolution

Ruby:
- module_function now maps to visibility 'private' in extractRubyVisibility
- module_function methods marked isStatic via backward-walk in isStatic
- Override semantics: private/public after module_function resets isStatic

* feat(go): Go MethodExtractor config with receiver-based extraction

Add Go as the 13th language with a per-language MethodExtractor config.
Go methods are top-level (not nested in struct bodies), so this adds
extractFromNode() to the MethodExtractor interface for direct method
node extraction without an enclosing class.

Config extracts:
- Name from field_identifier (methods) / identifier (functions)
- Return type including multi-return (first type from parameter_list)
- Parameters with variadic support
- Visibility via uppercase/lowercase convention
- Receiver type with pointer unwrapping (*User → User)
- isStatic for functions (no receiver)

Infrastructure:
- extractOwnerName optional hook on MethodExtractionConfig
- extractFromNode on MethodExtractor (factory auto-implements)
- Parse-worker uses extractFromNode when no enclosing class found
- method_declaration added to CLASS_CONTAINER_TYPES

* test: method enrichment integration tests for 7 languages + TS abstract class fix

Add method-enrichment integration test fixtures and test blocks for
Go, C++, Java, Kotlin, TypeScript, JavaScript, and C#. Each fixture
tests: class detection, HAS_METHOD edges, EXTENDS edges, isAbstract,
isStatic, annotations, parameterTypes, and CALLS edge resolution.

Fixes found during testing:
- Remove method_declaration from CLASS_CONTAINER_TYPES (added for Go
  but broke Java/C# HAS_METHOD edge resolution — method_declaration
  is also Java's method node type)
- Add abstract_class_declaration query to TypeScript tree-sitter
  queries (was missing, so abstract classes were invisible to pipeline)

1699 integration tests pass across 20 test files, 0 regressions.

* style: format typeDeclarationNodes array for better readability in PHP config

* fix: Go interface methods + Rust impl-for-Struct owner resolution

Go:
- Add method_elem to methodNodeTypes so interface method signatures
  are extractable as abstract methods
- Integration test: Animal interface detected, Speak isAbstract,
  CALLS edges from app.go

Rust:
- Add extractOwnerName to resolve impl Trait for Struct to the
  concrete Struct (not the Trait) — fixes method misattribution
- Fix findEnclosingClassId to generate Struct: label (not Impl:)
  for impl blocks so HAS_METHOD edges resolve to struct nodes
- Tighten abstract-dispatch test: assert SqlRepo owns find/save

generic.ts:
- Fix extractOwnerName fallback: when hook returns a value, skip
  both name-field and type_identifier scan (was overwriting result)

1703 integration tests pass, 0 regressions.

* fix: code review response — Rust impl label, Swift params, Dart async, sequential methodExtractor

Address code review findings from PR #624:

- ast-helpers: Rust `impl Trait for Struct` uses Struct label (matches existing
  graph node), plain `impl Struct` uses Impl label (matches definition.impl)
- swift: fix parameter type extraction (user_type not type_annotation), detect
  default values as function_declaration siblings, add version comment
- dart: isDartAsync now detects async*/sync* generators, add clarifying comment
  for declaration nodes in extension bodies
- python: correct isFinal comment (PEP 591 @typing.final exists, just not modeled)
- parsing-processor: port methodExtractor enrichment to sequential path so
  isAbstract/isStatic/visibility/annotations/isFinal populate on <15-file repos
- tests: remove silent `if (prop !== undefined)` guards, assert properties
  directly, fix label queries (Dart Method vs Function, Swift Method for protocol
  methods), add Rust HAS_METHOD sourceLabel tests, Swift parameterTypes tests,
  and Dart async/sync* integration tests with fixture

* fix: Rust grammar gap + qualified method IDs to resolve same-file collisions

Phase 1 — Rust grammar:
- Add function_signature_item query to RUST_QUERIES so abstract trait methods
  (fn speak(&self) -> String;) become graph nodes with isAbstract=true

Phase 2 — Qualified method IDs:
- findEnclosingClassInfo returns {classId, className} for AST-based class lookup
- Both parsing paths (sequential + worker) qualify method/property IDs with
  enclosing class: Method:file:ClassName.method instead of Method:file:method
- extractFuncNameFromSourceId handles ClassName.method format
- Fixes silent data loss when same-name methods in different classes shared a
  file (e.g., Animal.speak and Dog.speak both now exist as distinct graph nodes)

Test updates:
- Rust: abstract+concrete trait methods both verified, function count adjusted
- Python: static method disambiguation now emits 2 CALLS edges (correct — no
  more ID collision masking the second call)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: owner-aware resolution for qualified method IDs

Address Codex adversarial review findings after qualified ID change:

- findEnclosingFunction: disambiguate candidates by ownerId when multiple
  same-name methods exist in file; qualify fallback-generated IDs
- findEnclosingFunctionId (worker): qualify sourceIds with enclosing class
  name so CALLS source attribution matches definition-phase node IDs
- buildExportedTypeMapFromGraph: use lookupExactAll + nodeId match instead
  of lookupExactFull which returns first definition for bare name

* fix: methodExtractor variadic arity, return type preservation, PHP abstract dispatch

Three bugs in the methodExtractor enrichment path broke 17 integration tests:

1. Variadic parameterCount: buildMethodProps and parse-worker set
   parameterCount = info.parameters.length even for variadic functions,
   causing arity filtering to reject valid calls. Now checks isVariadic
   and sets parameterCount = undefined (matching extractMethodSignature).

2. C++ bare `...` token: extractCppParameters only iterated named
   children, missing the unnamed `...` token in C-style variadics like
   log_entry(const char* fmt, ...). Added fallback scan of all children.

3. Return type stripping: All 11 language extractReturnType functions
   used extractSimpleTypeName() which strips generic parameters
   (List<User> → "List", Task<User> → "Task"). Changed to .text?.trim()
   to preserve full generic types needed for for-loop iterable resolution,
   async-await binding, and return-type inference.

Also fixes PHP abstract dispatch test that matched SqlRepository instead
of the interface due to ambiguous filePath.includes('Repository') filter,
and adds parent-walk fallback in PHP isAbstract for extractFromNode path.

* chore: remove plan and review artifacts from PR

* fix: address Round 4 review findings + infrastructure improvements

- Ruby: add singleton_class support for class << self methods (4 new tests)
- PHP: add enum_declaration to CLASS_CONTAINER_TYPES
- Dart: add mixin/extension labels to CONTAINER_TYPE_TO_LABEL
- Swift: add TODO for unverifiable struct/enum node types on Node 22
- C#: add grammar version comment (0.23.1)
- Ruby: fix version comment range to pin (0.23.1)
- Rust/ast-helpers: add cross-reference comments for impl_item duplication
- ast-helpers: document CLASS_CONTAINER_TYPES ↔ typeDeclarationNodes invariant
- generic.ts: replace Array.includes with Set for O(1) dedup in addNestedBodies
- Go/Python/Ruby: align isAbstract signature with 2-param interface contract
- CLAUDE.md: fix malformed backtick around gitnexus:start HTML comment
- parsing-processor: add per-class method extraction cache (eliminates O(N*M))
- ast-helpers: add scoped_type_identifier to impl_item resolution
- call-processor: add dev-mode warnings at silent candidates[0] fallbacks
- MCP context(): surface methodMetadata for Method/Function/Constructor nodes
- resources.ts: update schema to list all stored Method properties

* fix: singleton_class HAS_METHOD edge regression in findEnclosingClassInfo

singleton_class (class << self) was added to CLASS_CONTAINER_TYPES but
has no name field — its receiver `self` has node type 'self', not
'identifier'. findEnclosingClassInfo now walks up to the enclosing
class/module to inherit its name, matching ruby.ts:extractOwnerName.

Also fixes findEnclosingClassNode in parse-worker.ts to skip
singleton_class and return the actual class/module node.

Adds integration test assertions for from_habitat (class << self method):
HAS_METHOD edge from Animal, isStatic=true, parameterCount=1.

feat(cpp): C/C++ MethodExtractor config with pure virtual detection (#617)
* feat(cpp): C/C++ MethodExtractor config with pure virtual detection (#572)

- Pure virtual (= 0) detected as isAbstract via token scanning
- virtual/final/override via hasKeyword and virtual_specifier children
- Access specifier visibility via backward sibling walk (public:/private:/protected:)
- Pointer/reference parameter types extracted correctly
- Constructor and destructor support via declaration node type
- Static detection via storage_class_specifier
- 16 new tests covering all acceptance criteria

* fix(cpp): isVirtual infers from override/final + out-of-class resolution

- isVirtual returns true for override/final methods (C++ mandates these
  are virtual)
- Add findClassNodeByQualifiedName to parse-worker: resolves Foo::bar()
  back to the Foo class declaration for method extractor enrichment
- Handles pointer/ref return types, constructors, destructors
- Integration test for virtual/static/constructor inline methods
- 233 unit+integration tests pass, 97 C++ resolver tests pass

* fix(cpp): address review — deep pointers, templates, unions, trailing returns

- Fix extractParamName: recursive unwrap for int** ptr → "ptr" (not "**ptr")
- Fix findFunctionDeclarator: recursive unwrap for multi-level pointer chains
- Template methods: generic extractor unwraps template_declaration to inner node
- union_specifier: added to typeDeclarationNodes, visibility defaults to public
- Trailing return type: auto foo() -> T now extracts T instead of "auto"
- Fix version comment: ^0.22.4 → ^0.23.4 to match package.json
- 4 new tests: double pointer params, template methods, union methods, trailing returns

* fix(cpp): template method visibility + union isTypeDeclaration test

extractCppVisibility now walks from the template_declaration parent
when the node is wrapped by a template, restoring correct access-
specifier resolution for templated class methods.

Also adds missing isTypeDeclaration assertion for union_specifier and
expands the template method test with explicit visibility checks.

* fix(cpp): address deep gap analysis review findings

- findClassNodeByQualifiedName: recursive pointer/reference
  declarator unwrap, fixing out-of-class linking for deep pointer
  return types (e.g. int** Foo::bar())
- findClassNodeByQualifiedName: recurse into namespace_definition
  blocks so namespace-wrapped classes resolve correctly
- Suppress = delete / = default special members from extraction
  via delete_method_clause / default_method_clause node detection
- Update known-gaps: namespace-wrapped classes, const-overload collapse
- Add tree-sitter-c version comment for consistency
- toBeFalsy() → toBe(undefined) for precise isVirtual assertion
- Tests: = delete, = default, = 0 non-regression, operator overloads,
  deep pointer return types, default visibility (class vs struct),
  multiple access specifier sections

feat(ts,js): TypeScript/JavaScript MethodExtractor config (#588)
* feat(ts,js): MethodExtractor config for TypeScript and JavaScript (#570)

Add per-language method extraction config following the established
JVM and C# patterns. Shared config base mirrors the field extractor's
typescript-javascript.ts pattern — TS-only node types are harmless
no-ops for JS.

Key features:
- isAbstract for abstract class methods and interface methods
- Parameter extraction with isOptional (?:, defaults) and isVariadic (...)
- Decorator extraction from preceding body-level siblings
- isAsync and isOverride detection
- Visibility via accessibility_modifier two-pass pattern
- Return type extraction unwrapping type_annotation

* test(ts,js): add override, getter/setter, destructured param tests

Address code review findings:
- Add override method detection test
- Add getter/setter extraction test
- Add destructured parameter with type annotation test
- Tighten constructor and private method assertions

* refactor(ts,js): address code review findings

- Replace O(M*N) decorator index scan with previousNamedSibling walk
- Remove dead findVisibility 'modifiers' fallback (TS uses
  accessibility_modifier, not a modifiers wrapper)
- Document call_signature/construct_signature as known gaps
- Document that TS constructors are method_definition nodes
- Remove unused findVisibility import

* fix(ts,js): type guard before cast, add generator/computed/overload tests

- Use type guard pattern (Set.has check before as-cast) in visibility
  extraction to ensure string is validated before narrowing
- Add generator method test (*items()) — confirms extraction works
- Add computed property name test ([Symbol.iterator]) — documents
  bracket-in-name behavior as intentional
- Add class-level method overload test — verifies overload signatures
  + implementation are all extracted

* fix(ts,js): detect #private methods as visibility 'private'

ES2022 private class methods (#name) use private_property_identifier
as their name node type. Detect this and return 'private' visibility
instead of the default 'public'.

* fix(ts,js): address review findings + close ingestion gaps

- hasKeyword/findVisibility: skip name field child to prevent false
  positives on soft-keyword method names (e.g. `abstract()`, `static()`)
- extractTsJsParameters: filter TS `this` parameter (compile-time only)
- extractMethodSignature: mirror `this`-param skip in fallback path
- tree-sitter queries: capture abstract_method_signature,
  method_signature, and private_property_identifier for TS; add
  private_property_identifier for JS
- Remove dead childForFieldName('name') fallbacks and typeFromAnnotation
  fallback
- Add 10+ unit tests, 4 integration tests through query pipeline

* test(ts): update HAS_METHOD count for interface method_signature capture

The new method_signature query now captures ILogger.log() as a Method
node with a HAS_METHOD edge, increasing the expected count from 4 to 5.

* fix(ts,js): address second review — async generator test, declare module gap

- Add async generator method test (async *values() → isAsync: true)
- Document declare module/global augmentation as known gap

feat(csharp): C# MethodExtractor config (#582)
* feat(csharp): add C# MethodExtractor config (#573)

Add C# method extraction config mirroring the JVM pattern from PR #576.
Wire csharpMethodConfig into the C# language provider and add 18 tests
covering classes, interfaces, abstract classes, structs, records,
constructors, params/out/ref/optional parameters, sealed methods,
attributes, and visibility modifiers.

* fix(csharp): add destructor, operator, conversion operator, and in-param support

- Add destructor_declaration, operator_declaration, and
  conversion_operator_declaration to methodNodeTypes
- Custom extractName for operators (e.g., "operator +", "implicit operator double")
- Fix extractReturnType for operator declarations (use type field, not returns)
- Add in modifier to parameter extraction (alongside out/ref)
- Add 4 new tests: destructor, operator+, implicit conversion, in parameter

* fix(csharp): add ref param test and document compound visibility limitation

- Add test for ref parameter modifier (was only testing out)
- Document that protected internal / private protected resolve to first modifier

* feat(csharp): support compound visibilities (protected internal, private protected)

- Add 'protected internal' and 'private protected' to FieldVisibility union
- Detect compound modifiers in both C# method and field extractors via
  collectModifierTexts helper scanning adjacent modifier nodes
- Add 2 tests for compound visibility detection

* feat(csharp): primary constructors, virtual/override/async, primary fields

Address all known limitations from review:

- Primary constructor support (C# 12): add extractPrimaryConstructor to
  MethodExtractionConfig and extractPrimaryFields to FieldExtractionConfig.
  Record params become public readonly properties; class params become
  private captured fields.
- Add isVirtual, isOverride, isAsync optional fields to MethodInfo,
  MethodExtractionConfig, NodeProperties, and parse-worker propagation.
- Detect virtual/override/async modifiers in C# method config.
- Move collectModifierTexts to shared helpers.ts (deduplicate).
- Fix destructor name to ~ClassName (disambiguates from constructor).
- Add expression-bodied method test.
- 118 tests total across method + field extraction suites, all passing.

* fix(csharp): review round 2 — annotations, record_struct, grammar pin

- Fix primary constructor annotations: use [] instead of extracting
  class-level attributes (C# has no syntax for ctor-specific attributes)
- Add record_struct_declaration to typeDeclarationNodes in both method
  and field extractors, CLASS_CONTAINER_TYPES, and isRecord visibility check
- Pin tree-sitter-c-sharp version (^0.23.1) in params comment

* fix(csharp): complete record_struct query + label mapping, sealed override test

- Add record_struct_declaration capture patterns to tree-sitter-queries.ts
  (type definition + primary constructor)
- Add record_struct_declaration → 'Struct' in CONTAINER_TYPE_TO_LABEL
- Assert isOverride: true alongside isFinal in sealed override test

* fix(csharp): record_struct label mismatch, add record struct + documented limitation tests

- Fix record_struct_declaration query tag: @definition.struct (not @definition.record)
  to match CONTAINER_TYPE_TO_LABEL and prevent broken HAS_METHOD edges
- Add 3 record struct tests: isTypeDeclaration, method extraction, primary constructor
- Add documented limitation tests: partial method (isAbstract: false), generic type
  parameter stripping (name excludes <T>)

* fix(csharp): remove record_struct_declaration — not a real tree-sitter node type

tree-sitter-c-sharp 0.23.1 parses 'record struct' as record_declaration
(absorbs the 'struct' keyword as an unnamed child token). The non-existent
record_struct_declaration in queries caused TSQueryErrorNodeType, breaking
ALL C# file processing.

Remove from: tree-sitter-queries.ts, typeDeclarationNodes in both
extractors, CLASS_CONTAINER_TYPES, and CONTAINER_TYPE_TO_LABEL.
Record struct types are already handled via record_declaration.

* feat(csharp): add isPartial support, filter targeted attributes, static ctor test

- Add isPartial optional field to MethodInfo, MethodExtractionConfig,
  NodeProperties, and parse-worker propagation pipeline
- Detect partial modifier in C# config — marks both declaration-only
  and implemented partial methods
- Filter targeted attribute lists (e.g. [return: MarshalAs(...)]) in
  extractCSharpAnnotations — only untargeted attributes collected
- Add static constructor test (isStatic: true, same name as class)
- Add 3 partial method tests: declaration-only, with body, coexisting pair
- Document record_struct/record_class as defensive dead code in
  export-detection.ts (grammar absorbs keywords into record_declaration)

* fix(csharp): this param for extension methods, dedup visibility, test fixes

- Handle this modifier on extension method parameters (type prefixed
  as 'this string', consistent with out/ref/in handling)
- Deduplicate visibility logic in extractPrimaryConstructor — reuse
  csharpMethodConfig.extractVisibility instead of inline compound check
- Fix record struct test title to reflect actual grammar behavior
- Add conversion operator returnType assertion
- Add extension method this parameter test

* fix(csharp): primary constructor line points to param list, empty name guard

- Use paramList.startPosition instead of ownerNode.startPosition for
  primary constructor line number (avoids methodInfoCache key collision)
- Guard against empty param names from tree-sitter error recovery nodes
