- Action:
- Create a channel or shared state for recommendation requests
- Send `RecommendationContext` to phrase intelligence service
- Receive recommendations and display in UI
- Estimated Time: 1-2 hours
- Priority: 🔴 Critical

### 3. Full Thread Integration
- [ ] Initialize and connect motion/voice/phrase intelligence in main.rs
- File: `apps/studio/src/main.rs`
- Current: Components are stubbed, threads not fully connected
- Action:
- Initialize `DellMotionReceiver` and `MotionTranslator`
- Initialize `VoiceRecognizer` and `VoiceCommandParser`
- Initialize `PhraseDatabase`, `PhraseRecommender`, `RecommendationService`
- Pass to respective threads
- Create action queue producer for motion/voice threads
- Estimated Time: 2-3 hours
- Priority: 🔴 Critical

🟡 High Priority (Beta Demo)

### 4. Voice Recognition Integration
- [ ] Integrate whisper-rs for actual voice recognition
- File: `crates/voice-control/src/recognizer.rs`
- Current: Stub implementation returns `None`
- Action:
- Add `whisper-rs` dependency (or alternative)
- Load Whisper model
- Convert f32 audio to i16 format
- Run inference
- Extract transcript and confidence
- Blocked On: Whisper model files
- Estimated Time: 4-6 hours (after model files)
- Priority: 🟡 High

### 5. Episode 1 API Connection
- [ ] Connect to real Episode 1 API endpoint
- File: `crates/motion-bridge/src/receiver.rs`
- Current: Ready but needs API endpoint URL
- Action:
- Configure API endpoint in `MotionReceiverConfig`
- Test with real Episode 1 data
- Handle authentication if needed
- Blocked On: Episode 1 API endpoint URL
- Estimated Time: 1-2 hours (after API available)
- Priority: 🟡 High

### 6. Performance Optimization
- [ ] Profile and optimize critical paths
- Areas:
- UI rendering (target: 60 FPS)
- Phrase recommendation latency (target: <5 ms)
- Motion/voice processing overhead
- Audio callback performance
- Action:
- Use `cargo flamegraph` or `perf` for profiling
- Identify bottlenecks
- Optimize hot paths
- Add performance telemetry
- Estimated Time: 4-6 hours
- Priority: 🟡 High

### 7. Beta Demo Preparation
- [ ] Create beta demo executable and video
- Action:
- Create `examples/beta_demo.rs` showcasing all features
- Record 5-minute demo video
- Document demo script
- Test all features work end-to-end
- Estimated Time: 1 day
- Priority: 🟡 High

🟢 Medium Priority (Post-Beta)

### 8. FAISS Integration (Optional)
- [ ] Replace linear search with FAISS for phrase similarity
- File: `crates/phrase-intelligence/src/database.rs`
- Current: Using linear search (works but slower)
- Action:
- Evaluate `faiss-rs` or `hnsw_rs` crates
- Integrate FAISS index
- Maintain backward compatibility
- Estimated Time: 2-3 hours
- Priority: 🟢 Medium (linear search is acceptable)

### 9. Link SDK Integration
- [ ] Complete Ableton Link SDK integration
- File: `crates/link-clock/src/link_clock.rs`
- Current: FFI infrastructure ready, needs SDK
- Action:
- Obtain Ableton Link SDK license
- Complete FFI bindings
- Test Link synchronization
- Blocked On: Ableton Link SDK license
- Estimated Time: 4-6 hours (after SDK)
- Priority: 🟢 Medium (LocalBeatClock works)

### 10. Error Handling & Recovery
- [ ] Add comprehensive error handling
- Areas:
- Audio engine errors
- Scheduler errors
- Motion/voice thread errors
- UI errors
- Action:
- Define error types
- Implement recovery strategies
- Add error telemetry
- Estimated Time: 4-6 hours
- Priority: 🟢 Medium

### 11. Integration Tests
- [ ] Create end-to-end integration tests
- Action:
- Test motion → action pipeline
- Test voice → action pipeline
- Test phrase recommendation → deck load
- Test UI → engine communication
- Estimated Time: 4-6 hours
- Priority: 🟢 Medium
