11-task plan across 4 chunks: Training Guard kernel + wrapper (Tasks 1-3), wire into trainer (Tasks 4-6), Q-value monitor + action routing (Tasks 7-9), experience collector audit + final verification (Tasks 10-11). Eliminates all 10 GPU→CPU sync barriers from the DQN training hot path. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
