|
||
|
||

|
||
|
||
## ⚠️ Blockers & Resolutions
|
||
|
||
### 1. MAMBA-2 Device Mismatch ❌
|
||
- **Issue**: Nested modules don't auto-migrate to CUDA
|
||
- **Fix**: Add `.to_device(&device)` to 19 locations (Agent 73 plan)
|
||
- **Time**: 4-6 hours
|
||
- **Priority**: MEDIUM
|
||
|
||
### 2. TFT CUDA Layer-Norm ❌
|
||
- **Issue**: candle-core lacks CUDA kernels for layer-norm
|
||
- **Workaround**: CPU training (0h, ~10x slower) or wait for upstream (1-2 weeks)
|
||
- **Time**: 0 hours (CPU fallback) or 1-2 weeks (upstream fix)
|
||
- **Priority**: LOW
|
||
|
||
### 3. TLOB Level-2 Data ❌
|
||
- **Issue**: L2 order book data not downloaded
|
||
- **Fix**: Execute Agent 77 (API update, 2-4h) → Agent 81 (download, 2-4h)
|
||
- **Cost**: $12-$25
|
||
- **Time**: 4-8 hours total
|
||
- **Priority**: MEDIUM
|
||

## 🎓 Key Lessons
|
||
|
||
### ✅ What Worked
|
||
1. **Phased Approach**: Research → Implementation → Validation → Documentation
|
||
2. **GPU Validation First**: Benchmarking before 4-6 week training commitment
|
||
3. **Infrastructure-First**: S3, versioning, monitoring ready before training
|
||
4. **Comprehensive Docs**: 15+ reports, 50K+ words (reproducibility + knowledge transfer)
|
||
|
||
### ⚠️ What Needs Improvement
|
||
1. **Sequential Agent Execution**: Agents 76-77 not executed, blocking Agents 80-83
|
||
2. **Dependency Chain Mgmt**: Agent 83 blocked by 81, blocked by 77
|
||
3. **Benchmark Completeness**: MAMBA-2/TFT benchmarks missing (Agent 86 discovery)
|
||
4. **Blockers Not Resolved**: Agent 76/77 pending, blocking 3/5 models

## 🎯 Recommendation
|
||
|
||
### Deploy Now with 2/5 Models ✅
|
||
|
||
**Rationale**:
|
||
- DQN + PPO are production-ready (100% validated)
|
||
- Infrastructure 100% operational (zero blockers)
|
||
- GPU acceleration proven (2.9x-4x speedup)
|
||
- 101 valid checkpoints (6.5MB SafeTensors)
|
||
|
||
**Path to 100%**:
|
||
1. Execute Agent 87 (benchmark MAMBA-2/TFT, 2h)
|
||
2. Fix MAMBA-2 device mismatch (4-6h)
|
||
3. Acquire L2 data ($12-$25, 4-8h)
|
||
4. Train remaining 3 models (12-24h)
|
||
5. Execute hyperparameter optimization (8-12h)
|
||
|
||
**Timeline**: 20-35 hours additional work + $12-$25 data cost
