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 ✅

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%:
