## Dead Code Analysis

### Confirmed Dead Code
None found. All public items are consumed by downstream crates or are intentionally platform-gated.

### Platform-Gated (Intentional)
- `AndroidVoiceUnit`, `IosVoiceUnit` — only compiled on target platforms
- `chanora_android_*` JNI functions — Android only
- `ios_voice_unit.rs`, `android_voice_unit.rs` — platform-specific
- `sdl_output.rs` — Linux only

### TODO/FIXME Items (15 total)

| File | Line | Note |
|------|------|------|
| `chanora_audio/src/audio_event_queue.rs` | 27 | Wire to client disconnect path |
| `chanora_audio/src/engine.rs` | 2348 | Realtime audio callback concern |
| `chanora_audio/src/mobile_voice_backend.rs` | 16 | Back-fill IosVoiceUnit to trait |
| `audio_lifecycle_service.dart` | 151 | Wire macOS default device change |

| `poke_notification_service.dart` | 33,35,41,43,48,130,132,142,155,168 | Future EventSoundService (10 items) |

### Useless Code
- No empty impls found
- No commented-out function bodies found
- No dead trait implementations found

## Architecture Notes

- **Boundary discipline**: `tsclientlib` types never cross `chanora_protocol` boundary (SAD-067)
- **Single connection**: DEC-006 enforces one connection at runtime
- **Secret isolation**: `chanora_storage` never stores secrets in plaintext DB
- **Deterministic reducers**: `chanora_state` reducers are pure functions (SRS-056)
- **PTT privacy**: Raw key codes never appear in logs or diagnostics (DEC-027)
- **Audio pipeline**: 48kHz mono, 20ms Opus frames, 10ms processing frames
