## Key Findings

### Well-Covered Features
- **F-004 (BYOK Cloud Keys)**: All 4 criteria have tests
- **F-006 (Cost Tracking)**: All 4 criteria have tests
- **F-007 (Exact Hash Cache)**: 3/4 criteria tested (latency not verified)

### Partially Covered Features
- **F-001 (OpenAI Proxy)**: Error cases tested, success cases missing
- **F-002 (Anthropic Proxy)**: Error cases tested, success cases missing
- **F-005 (Rule-Based Router)**: Basic routing tested, "auto" mode and cloud fallback missing
- **F-009 (Web Dashboard)**: HTML endpoint tested, WebSocket and baseline capture missing
- **F-011 (llmhosts doctor)**: Runs without crash, but checks not verified

### Missing Coverage
- **F-003 (Ollama Auto-Discovery)**: Code exists but no tests (requires Ollama running)
- **F-008 (TUI Dashboard)**: No tests found
- **F-010 (llmhosts serve)**: No integration tests
- **F-012 (Hardware Detection)**: Code exists but no tests
- **F-013 through F-020**: Not implemented (Phase 2+ features)

## Recommendations

1. **Add integration tests** for `llmhosts serve` startup sequence
2. **Add tests for Ollama discovery** (mock Ollama or use test container)
3. **Add tests for TUI dashboard** (if textual/rich library supports headless testing)
4. **Add latency assertions** for cache operations (<5ms requirement)
5. **Add tests for transparency metadata** in API responses
6. **Add tests for "auto" routing mode** and cloud fallback
7. **Add WebSocket tests** for real-time dashboard updates
8. **Add performance tests** for startup time (<5s) and doctor (<10s)
