+## 2026-05-21 — p10-1D: typedef-wrapped struct/enum in C falls into glue
+
+**Origin**: PR #156 (p10-1d) code-reviewer review. Verified during dogfood.
+
+**Symptom**: `typedef struct { ... } Foo;` in a `.c` file does NOT emit a struct-level unit. tree-sitter-c classifies the construct as a top-level `type_definition` with an *anonymous* inner `struct_specifier` (no `name` field), so the extractor's `struct_specifier` arm doesn't fire — the whole declaration falls into `<top-level>` glue. The named typedef alias `Foo` is therefore not searchable as a symbol.
+
+**Status**: Consistent with spec p10-1d-c-cpp-ast-chunker.md's Risks/notes ("Anonymous union / struct … anonymous → glue"), but the spec's main body line 22 ("struct_specifier (named, top-level) → 1 unit") suggests this idiom WOULD emit. Tension noted, not yet fixed.
+
+**Workaround**: search the struct by its field/function names, or use `--code-lang c` to broaden scope. Typedef-aliased struct names won't surface as `Citation::Code.symbol`.
+
+**Next step**: dogfood real C code for a week+; if this turns out to be a frequent pain point (kernel-style code, libuv, etc.), revisit the extractor to detect `type_definition` → inner `struct_specifier` and emit a synthetic unit named after the typedef alias.

 ## 2026-05-20 — p10-1B: Rust 1A-2 symbol path is file-scope-only; 1B+ uses workspace path → module prefix
 
 **무엇이 바뀌었나**: P10-1A-2 의 Rust `code-rust-ast-v1` chunker 가 생성하는 symbol 은 file-scope mod-path nesting 만 사용한다 (예: `Foo::double`). P10-1B 이후 Python / TypeScript / JavaScript 의 symbol 은 workspace 경로 → module path prefix 를 포함한다 (예: `kebab_eval.metrics.compute_mrr`, `src/Foo.Foo.search`).

 - **Template specialization** (`template<> class Foo<int>`): tree-sitter-cpp 의 `template_declaration` 안의 `class_specifier` name 만 추출 — `Foo` 만 symbol 에 들어가고 `<int>` 미포함. design 의 generic 무시 룰 일관.
 - **`extern "C"` block 안의 fn**: 일반 fn 처리. 외부 wrapping block 은 glue.
 - **Anonymous union / struct** (`struct { int x; }` 변수 안에): 흔치 않음 + named 만 unit. anonymous 는 glue.
+- **typedef-wrapped struct/enum idiom** (`typedef struct { ... } Foo;`) — anonymous inner struct → glue. Named typedef alias 미캡처. dogfood 후 HOTFIXES 검토. See [HOTFIXES.md 2026-05-21 entry](../HOTFIXES.md).
 - **Macro-heavy code** (Linux kernel 등): `#define FOO(x) ...` 매크로가 function-like 라도 parser 가 fn 으로 인식 안 함. preprocessor glue 로 처리 — symbol 안 잡힘. 의도된 동작 (parser 의 macro expansion 안 함).
 - **`__attribute__((...))`** annotations: tree-sitter-c 의 attribute 노드는 declarator 옆 sibling. 무시 가능. function name 추출에 영향 없음.
