## Root Cause Analysis
|
||||
|
||||
### Primary Issues
|
||||
|
||||
1. **Library-First-Hybrid Mode Not Triggering**
|
||||
- Sessions are generating in `midi-first` mode or no mode set
|
||||
- `library_first_mode` is None or False instead of True
|
||||
- This prevents pack coherence calculation and bus-aware selection
|
||||
|
||||
2. **Piano Hybrid Truth Not Materializing**
|
||||
- `mandatory_midi_hook.materialized` is consistently false
|
||||
- `has_hybrid_piano` is None or false
|
||||
- The P3 hook reservation is happening but not actually creating tracks
|
||||
|
||||
3. **Pack Coherence Metrics Missing**
|
||||
- `pack_coherence` field not being written to manifest
|
||||
- DOMINANT_PALETTE logs show coherence calculation but not persisting
|
||||
- Missing connection between layer selection audit and manifest
|
||||
|
||||
4. **Coherence Score Below Threshold**
|
||||
- All sessions scoring 4.6-5.6 (target: >= 6.5)
|
||||
- Structural fixes still needed in arrangement
|
||||
|
||||
---
|
||||
|
||||
## Recommendations for Next Sprint
|
||||
|
||||
### Critical Fixes Needed
|
||||
|
||||
1. **Fix Library-First-Hybrid Mode Detection**
|
||||
- Ensure `library_first_mode=true` when reference_path is provided
|
||||
- Verify mode is being passed through generation pipeline
|
||||
- Add explicit mode enforcement in `generate_track`
|
||||
|
||||
2. **Fix MIDI Hook Materialization**
|
||||
- Debug why `mandatory_midi_hook.materialized` remains false
|
||||
- Ensure P3 hook actually creates a MIDI track
|
||||
- Add validation that hook is materialized before completing
|
||||
|
||||
3. **Fix Pack Coherence Persistence**
|
||||
- Connect layer selection audit to manifest persistence
|
||||
- Ensure `pack_coherence` dict is written to generation_manifests.json
|
||||
- Add senior validation to verify coherence before marking complete
|
||||
|
||||
4. **Improve Coherence Scoring**
|
||||
- Structural arrangement fixes needed
|
||||
- Consider additional musical theme enforcement
|
||||
- Evaluate judge results integration

## Conclusion
|
||||
|
||||
**Sprint v0.1.17 is NOT COMPLETE.**
|
||||
|
||||
While the P0-P5 code implementations are deployed, the system is not meeting the required thresholds for a successful library-first-hybrid generation with piano truth validation. The next sprint must focus on:
|
||||
|
||||
1. Fixing the library-first-hybrid mode activation
|
||||
2. Ensuring MIDI hook materialization
|
||||
3. Connecting pack coherence to manifest persistence
|
||||
4. Raising coherence scores above 6.5
|
||||
|
||||
**Do not declare Sprint v0.1.17 complete until a session is generated with:**
|
||||
- `coherence_score >= 6.5`
|
||||
- `pack_coherence.music >= 0.65`
|
||||
- `pack_coherence.overall >= 0.50`
|
||||
- `mandatory_midi_hook.materialized == true`
|
||||
- `generation_mode == "library-first-hybrid"`
