Wave 160 Phase 2 Progress:
  ✅ Agent 53: DQN Training Complete
  ✅ Agent 54: PPO Training Complete ← YOU ARE HERE
  ⏳ Agent 55: TFT Training (Next)
  ⏳ Agent 56: MAMBA-2 Training (After TFT)

Recommendations:
  1. ⚠️  Value Network: Explained variance 0.4413 < 0.5 threshold
     → Consider increasing epochs or tuning value_learning_rate
  2. 🚀 GPU Acceleration: Enable --use-gpu flag for 10-50x speedup (RTX 3050 Ti)
  3. 📊 Multi-Day Training: Extend to 4 available files (Jan 2-5, 2024)
  4. 🧪 Learning Rate Test: Validate Agent 32's 3e-5 vs current 0.0003
