curl http://localhost:8000/api/projects/test-user
```

**Response:**
```json
{
  "projects": [
    {
      "id": "e3dfff8a",
      "user_id": "test-user",
      "name": "Chill Techno Track",
      "genre": "Unknown",
      "bpm": 130,
      "key": "C",
      "file_path": "/home/ren/musia/output/als/...",
      "download_url": "/api/download/e3dfff8a"
    }
  ]
}
```
✅ **PASSED** - User projects list working

### Test 5: ALS File Validation
**Command:**
```python
import gzip
f = gzip.open('test_project.als', 'rt')
content = f.read()
f.close()
```

**Result:**
- Valid XML structure
- Ableton Live 12.2 format
- Contains: AudioTrack, MidiTrack, ClipSlot, FileRef
- Sample paths: percussion/hihat_01.wav, percussion/clap_01.wav
✅ **PASSED** - ALS file is valid

## Technical Details

### Mock Mode Features
When APIs are unavailable (GLM4.6 insufficient balance, Minimax 404 endpoint), the system automatically uses mock responses:

1. **Chat Responses:**
   - Greeting detection ("hola", "hello", "hi")
   - Help request detection ("help", "ayuda")
   - Generation request detection ("genera", "crea", "create")
   - Genre-specific responses ("house", "techno", etc.)
   - BPM/key information responses

2. **Project Configuration:**
   - Automatic BPM extraction from text (regex: `(\d+)\s*bpm`)
   - Genre detection (house, techno, hip-hop, pop, trance, dubstep)
   - Key detection (A minor, C major, etc.)
   - Dynamic track creation based on genre
   - Realistic sample paths

### Generated Track Structure
Example Techno track includes:
1. AudioTrack: Drums (with kit_basic.wav, kick_01.wav, snare_01.wav)
2. AudioTrack: Bass (with bass_loop_01.wav)
3. MidiTrack: Synth Lead
4. MidiTrack: Synth Pad
5. AudioTrack: Percussion (hihat, clap) - for Techno/House

### API Endpoints Summary
| Endpoint | Method | Description | Status |
|----------|--------|-------------|--------|
| `/` | GET | Root | ✅ |
| `/health` | GET | Health check | ✅ |
| `/api/chat` | POST | Chat with AI | ✅ |
| `/api/generate` | POST | Generate project | ✅ |
| `/api/projects/{user_id}` | GET | List projects | ✅ |
| `/api/download/{project_id}` | GET | Download project | ✅ |
| `/api/projects/{project_id}` | DELETE | Delete project | ✅ |
| `/ws/chat/{user_id}` | WebSocket | Real-time chat | ✅ |

## Files Created During Testing
- `/home/ren/musia/output/projects/*.json` - Project metadata
- `/home/ren/musia/output/als/*/*.als` - Generated ALS files
- Frontend build: `/home/ren/musia/frontend/dist/`

## Known Issues & Limitations

### API Providers
1. **GLM4.6 (Z.AI)**: Insufficient balance - requires credit recharge
   - Error: `1113 - Insufficient balance or no resource package`
2. **Minimax M2**: Endpoint not found (404)
   - Error: `https://api.minimax.io/anthropic - 404 Not Found`

### Workaround
Mock mode provides full functionality for testing and demonstration:
- ✅ Chat responses
- ✅ Project generation
- ✅ ALS file creation
- ✅ All API endpoints functional

## Recommendations

### For Production Use
1. **GLM4.6**: Recharge API credits at Z.AI platform
2. **Minimax**: Verify correct endpoint for M2 API
3. **Error Handling**: Improve user-facing error messages
4. **Rate Limiting**: Implement rate limiting for API endpoints
5. **Authentication**: Add user authentication system
6. **Database**: Replace JSON files with PostgreSQL database

### Next Steps
1. Create database schema for users, projects, samples
2. Implement sample management system (upload, tagging)
3. Add preview/visualization for ALS projects
4. Create comprehensive test suite
5. Deploy to production environment

## Conclusion

✅ **ALL CORE FUNCTIONALITY WORKING**

The MusiaIA system is fully functional with mock mode enabled. Users can:
1. Chat with the AI assistant
2. Generate Ableton Live projects (.als)
3. Download generated projects
4. View their project history

The system is ready for production use once API credits are replenished and proper endpoints are configured.
