### Step 494: Annotate Whetstone's Own Code
**Status:** PASS (12/12 tests)
Builds a self-host annotation audit pass over parsed Whetstone headers to
measure inferred annotation signals (`@Complexity`, `@Risk`, `@Owner`,
`@Intent`, `@TailCall`) on the codebase itself.
**Files added:**
- `editor/src/SelfHostAnnotationAudit.h` — annotation audit layer:
- `FileAnnotationAudit`, `SelfAnnotationAuditReport`
- integrates:
- `SelfHostHarness` parsing
- `AnnotationInference::inferAll(...)`
- `SafetyAuditor` risk signal extraction
- per-file/aggregate metrics:
- inferred annotation totals
- complexity counts
- risk counts (safety findings + unsafe cast/pointer pattern signals)
- owner counts (inference + smart-pointer pattern signals)
- intent counts from descriptive function names
- tail-call counts
- inline-source audit mode for focused rule tests
- `editor/tests/step494_test.cpp` — 12 tests covering:
- real-corpus audit execution and parse-rate metrics
- category signal extraction (complexity/risk/owner/intent/tailcall)
- negative path for unparseable input
- aggregate-vs-per-file metric consistency
- real-corpus non-zero signal checks
- `editor/CMakeLists.txt` — `step494_test` target
**Verification run:**
- `cmake --build editor/build-native --target step494_test step493_test` — PASS
- `./editor/build-native/step494_test` — PASS (12/12)
- `./editor/build-native/step493_test` — PASS (12/12) regression coverage
**Architecture gate check:**
- `editor/src/SelfHostAnnotationAudit.h` within header-size limit (`180` <= `600`)
- `editor/tests/step494_test.cpp` within test-file size guidance (`142` lines)
- Header-only architecture and naming conventions remain aligned with `ARCHITECTURE.md`
