The shipped grammar parses every record form as record_declaration (no
record_struct_declaration node), so 'record struct' mis-kinded as class.
classifyClassNode now distinguishes the value-type form by its struct
keyword child, and extractStruct accepts bodiless positional records
(the no-body gate is for C/C++ forward declarations) instead of
crashing mid-file on them.

A C# method called through a static factory or fluent chain —
`Foo.Create().Bar()`, `JObject.Parse(s).Property(...)`,
`Instant.FromUtc(...).InZone(zone)` — lost the receiver's type, so the chained
method didn't resolve and the call was invisible to callers/impact/trace. Ports
the #645/#608 mechanism to C# (additive, like Java #751):
- Part 1: capture C# return types in the extractor, reading the `returns` field
(`static Foo Create()` -> `Foo`); predefined/array/generic/nullable/namespaced
types are normalized or skipped.
- Part 2: encode a chained `member_access_expression` receiver
(`Foo.Create(args).Bar()`) as `inner().Bar` with normalized empty parens, so
factory calls that take arguments still split. Non-chained member calls keep
their existing `recv.Method` text.
- Part 3: resolve via the shared matchDottedCallChain (now Java/Kotlin/C#),
validated by resolveMethodOnType so a wrong inference yields NO edge.
Known limitation (safe): C# extension-method chains don't resolve, since the
method lives on the extension class, not the receiver's type — no edge, never a
wrong one.
Validated: synthetic decoy + args + absent-method safety tests; full suite green;

Vendor tree-sitter-c-sharp 0.23.5 (ABI 15) for C#, replacing the bundled ABI-13
build that dropped primary-constructor classes. Adds native primary-ctor
parsing, primary-ctor parameter dependency edges, return-type extraction via the
renamed `returns` field, and a preParse that blanks `#if` directive lines the
new grammar mis-parses inside enum bodies. Validated on MediatR / eShopOnWeb /
Newtonsoft.Json + full suite.

Completes the cross-file dependency graph behind impact / affected / explore across all 22 supported languages and 14 web frameworks, validated on real-world repos (measured fair-coverage table added to the README). Per-language resolution + framework resolvers/synthesizers (Lua/Luau require, Shopify OS 2.0 Liquid sections, Delphi forms, Rust cross-module + Rocket macros, Swift Fluent, SvelteKit/Nuxt loader/component conventions, RN/Expo bridges). 0 cross-family false edges, full suite green (1187 passed). See #708.

Indexing any C# project produced zero `references` edges, so
`codegraph_callers SomeDto` returned no hits even when the DTO was used
as a param/return type across the codebase, and `codegraph_callees` on
a service class only saw its `using` imports — the headline structural
query silently degraded to text-search on half of every typical backend
stack.
Two root causes:
1. `csharp.ts` was missing `returnField` (default `'return_type'` doesn't
exist on C# AST; the field is `'type'`) AND had
`paramsField:'parameter_list'` (the node TYPE, not the field NAME
`'parameters'`) — so parameter type extraction silently no-op'd.
2. `extractTypeRefsFromSubtree` only emitted refs for `type_identifier`
leaves. C# tree-sitter doesn't produce `type_identifier` — it uses
`identifier`, `predefined_type`, `qualified_name`, `generic_name`,
`array_type`, `nullable_type`, `tuple_type`, etc.
Fix:
- `csharp.ts`: `paramsField:'parameters'`, `returnField:'type'`.
- Route C# through a dedicated `extractCsharpTypeRefs` +
`walkCsharpTypePosition`. Descends ONLY into known type fields
(`parameter.type`, `method.type`, `property.type`,
`variable_declaration.type`, `tuple_element.type`), so parameter
NAMES like `request` in `Build(UserDto request)` never leak as type
refs.
- Hook `extractField` and `extractProperty` to call
`extractTypeAnnotations` so property/field type refs land in the graph.
Validation on dotnet/eShop (527 .cs files):
C# `references` edges: 35 -> 925 (+26x)
No regression in calls/imports/instantiates/extends/implements.
Closes#381.
Addresses C#'s property_declaration nodes (public string Name { get; set; }) by adding propertyTypes support and extractProperty method. Improves field extraction to handle C#'s nested variable_declaration > variable_declarator structure. Adds base_list handling in extractInheritance for C#'s `: Parent, IInterface` syntax where base class and interfaces are combined in a single colon-separated list.
Adds nameMatchBonus scoring to prioritize results where node names exactly or partially match query terms. Implements dedicated field extraction for Java/C# to properly categorize class fields vs variables. Optimizes BM25 search with column weights favoring name matches and increased result fetching before post-processing. Refines stop words list to preserve common programming terms like "get", "find", "list".
Extends AST parsing to identify and extract individual enum members/cases for better code analysis. Adds enumMemberTypes configuration to each language extractor with language-specific node types (e.g., 'enum_variant' for Rust, 'enum_case' for PHP, 'enum_entry' for Swift/Kotlin). Implements flexible member name resolution supporting both field-based and identifier-based extraction patterns.
Splits the monolithic tree-sitter.ts (3,358 lines) into modular files:
- 14 language config files under src/extraction/languages/
- 3 standalone extractors (Liquid, Svelte, DFM)
- Shared helpers and types modules to avoid circular imports
Also fixes a bug where Java's extractImport hook incorrectly set
handledRefs: true, preventing unresolved reference creation and
degrading codegraph_explore results for Java codebases.
