### Technical Evidence

#### Micro-Stem Analysis (Pre-Generation)
✅ **Phrases/Segments**: 33 sections detected  
✅ **Dominant Families**: 
- ss_rnbl: 48 matches (bass, drums)
- impact cell: 21 matches (FX)
- kick bigcayu: 20 matches (drums)
- midilatino_zara: 11 matches (atmos/pad)
- pluck 7: 6 matches (melodic)

✅ **Token DNA Profile**:
- dembow: 118 (dominant groove)
- reese: 31 (bass character)
- pluck: 12 (melodic hooks)
- pad: 11 (harmonic beds)

#### Generation Results
❌ **Completion**: Job timeout at 300s (max polls reached)  
⚠️ **Tracks Created**: 165 total (97 MIDI + 68 audio) - exceeds 12-track budget  
⚠️ **Coherence Score**: N/A (job did not complete)  
⚠️ **Same-pack ratio**: N/A (manifest not generated)  
⚠️ **Core/optional ratio**: N/A  

#### Infrastructure Verification
✅ **MCP Connection**: Active on 127.0.0.1:9877  
✅ **Ableton Control Surface**: AbletonMCP_AI loaded  
✅ **Sample Library**: 510 samples indexed  
✅ **Audio Devices**: Simpler loaded on audio tracks  
✅ **Bus Routing**: DRUM BUS, BASS BUS, MUSIC BUS created  

---

### Section Variants Generated

✅ **Phrase Plan Present**: 4 sections configured
- Section 0 (intro): drum=skip, bass=pedal, melodic=motif
- Section 1 (build): drum=straight, bass=syncopated, melodic=lift
- Section 2 (break): drum=skip, bass=pedal, melodic=response
- Section 3 (outro): drum=straight, bass=pedal, melodic=descend

✅ **Musical Theme Initialized**: key=Dm, scale=minor, seed=8057  
⚠️ **Key Mismatch Warning**: Reference is Am but generation used Dm

---

### Coherence Metrics (From Last Successful Manifest)

Last audited manifest (session_id = fadbe771353b):
- Budget logical: 11/12 ✅
- Core/optional: 55% ✅
- Same-pack ratio: 53% ⚠️ (target >70%)
- Tonal consistency: 10/10 samples in conflict against Fm ❌
- Redundant layers: 16 ❌ (too many)

---

### Issues Identified

1. **Timeout Problem**: Generation exceeds 300s timeout limit
   - Impact: Cannot complete full materialization
   - Evidence: smoke_test_async_report.json shows "Timeout: max polls (60) reached"

2. **Track Overcrowding**: 165 tracks created vs 12-track budget
   - Impact: Cluttered session, hard to mix
   - Evidence: Previous run created 165 tracks

3. **Key Drift**: Generation used Dm, reference is Am
   - Impact: Harmonic mismatch with reference
   - Evidence: Log shows "[THEME] Initialized musical theme: key=Dm"

4. **No Manifest Generated**: Cannot verify coherence scores
   - Impact: Missing post-generation validation data
   - Evidence: "get_generation_manifest: Skipped (job did not complete)"

---

### What Worked

✅ **Micro-stem extraction**: Successfully analyzed ejemplo.mp3  
✅ **Sample matching**: Found compatible samples from ss_rnbl family  
✅ **Section detection**: Identified 33 segments with energy/brightness profiles  
✅ **Bus structure**: DRUM, BASS, MUSIC, VOCAL LATIN, FX buses created  
✅ **Audio materialization**: Simpler devices loaded, arrangement patterns placed  
✅ **Gain staging**: Latin-style adjustments applied  

---

### What Needs Improvement

❌ **Generation speed**: Must complete within 300s timeout  
❌ **Track budget**: Must respect 12-track limit  
❌ **Key consistency**: Generation should match reference key (Am)  
❌ **Coherence validation**: Need manifest to verify same-pack ratio >70%

### Auditory Assessment

**Status**: PENDING USER LISTENING

Please listen to the generated track in Ableton and rate:

| Aspect | Score | Notes |
|--------|-------|-------|
| Sounds like reference | _/10 | Does it match ejemplo.mp3 vibe? |
| Hook recognizable | YES/NO | Is there a clear melodic identity? |
| Coherent sections | YES/NO | Do sections flow logically? |
| Bass-chords-lead alignment | YES/NO | Are harmonics consistent? |
| Pack coherence | YES/NO | Do sounds feel from same "world"? |

### Verdict

**PARTIAL / NEEDS FIXES**

The new implementation shows **significant infrastructure progress**:
- Micro-stem analysis working
- Section-aware generation
- Pack-family selection logic
- Bus routing operational

However, **critical blockers prevent validation**:
- Generation timeout prevents completion
- Track budget exceeded
- Key mismatch with reference
- No coherence metrics available

---

### Next Steps

**Priority 1 - Fix Timeout**:
1. Optimize generation speed or increase timeout
2. Add progress checkpointing for resume capability
3. Profile bottleneck in materialization phase

**Priority 2 - Respect Budget**:
1. Enforce 12-track limit strictly
2. Remove redundant layers (16 detected)
3. Use MIDI/presets for harmonic material when available

**Priority 3 - Fix Key Consistency**:
1. Force generation key to match reference (Am)
2. Validate bass-music harmonic compatibility
3. Reject samples with conflicting keys

**Priority 4 - Complete Validation**:
1. Re-run smoke test after fixes
2. Capture coherence metrics from manifest
3. User auditory review
4. Compare generated vs reference spectrograms
