⚠️ 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

- ⚠️ Paper Trading: 30-90 days validation
Total Time to 100%: 20-35 hours + $12-$25 data cost
🎓 Key Lessons
✅ What Worked
- Phased Approach: Research → Implementation → Validation → Documentation
- GPU Validation First: Benchmarking before 4-6 week training commitment
- Infrastructure-First: S3, versioning, monitoring ready before training
- Comprehensive Docs: 15+ reports, 50K+ words (reproducibility + knowledge transfer)
⚠️ What Needs Improvement
- Sequential Agent Execution: Agents 76-77 not executed, blocking Agents 80-83
- Dependency Chain Mgmt: Agent 83 blocked by 81, blocked by 77
- Benchmark Completeness: MAMBA-2/TFT benchmarks missing (Agent 86 discovery)
- Blockers Not Resolved: Agent 76/77 pending, blocking 3/5 models
🎯 Recommendation
Deploy Now with 2/5 Models ✅
