- v_min/v_max: -2/+2 → -10/+10 (C51 needs room to separate 45 actions) - entropy_coefficient: 0.01 → 0.05 (5x stronger anti-collapse) - cql_alpha: 1.0 → 0.1 (was adding ~3.8 loss penalty per step) - use_iqn: true → false (IQN trains q_network but inference uses dist_dueling) - Added get_count_bonuses() method for batch action selection Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
