### Step 495: Transpile Whetstone Modules
**Status:** PASS (12/12 tests)
Adds a self-host transpilation audit for three concrete Whetstone headers:
`AnnotationConflictExtended.h` -> Python, `ResponseBudget.h` -> Rust,
`Icons.h` -> Java, with structure/annotation preservation and confidence
metrics.
**Files added:**
- `editor/src/SelfHostTranspileAudit.h` — self-host transpilation audit layer:
- `SelfTranspileSpec`, `SelfTranspileFileReport`, `SelfTranspileAuditReport`
- default spec set for the three sprint-target headers
- source parse (`cpp`) -> projection (`CrossLanguageProjector`) -> target generation
- checks:
- source parse success
- projection success
- annotation preservation (`annotationsPreserved`)
- generated output non-empty
- target-language parse viability
- confidence scoring via `TranspilationScorer`
- idiomatic vs literal classification derived from confidence category
- deterministic fallback generation scaffold when primary generator returns empty
- `editor/tests/step495_test.cpp` — 12 tests covering:
- expected header/target mapping set
- per-file audit shape and success metrics
- non-empty generation guarantees
- annotation-preservation checks
- confidence and aggregate metric bounds
- idiomatic/literal accounting and summary notes
- `editor/CMakeLists.txt` — `step495_test` target
**Verification run:**
- `cmake --build editor/build-native --target step495_test step494_test` — PASS
- `./editor/build-native/step495_test` — PASS (12/12)
- `./editor/build-native/step494_test` — PASS (12/12) regression coverage
**Architecture gate check:**
- `editor/src/SelfHostTranspileAudit.h` within header-size limit (`178` <= `600`)
- `editor/tests/step495_test.cpp` within test-file size guidance (`139` lines)
- Header-only architecture and naming conventions remain aligned with `ARCHITECTURE.md`
