  If optimization fails:

  1. Deploy 3-model ensemble (DQN + PPO + MAMBA-2)
     → All models meet <5ms P95 latency target
     → Total GPU memory: 315MB (well under 4GB budget)

  2. Use TFT for batch predictions (non-latency-critical)
     → Batch size = 8 → 1.76ms per sample throughput
     → 570 samples/sec (acceptable for non-real-time use)

  3. Defer TFT real-time to GPU upgrade (8GB+ VRAM)
     → RTX 4060 Ti (8GB) or RTX 4070 (12GB)
     → Cost: $300-400 hardware investment
