| - Source note: conservative continuation from the externally audited First Attack frozen checkpoint, with fresh optimizer LR `1e-6`, deterministic collection, and `freeze_batch_norm_stats=true` to avoid BatchNorm running-stat drift. |
| - Evaluation note: final training-time bot-mode fixed-bot eval on 2026-05-25, 20 games, 50 simulations, rule bot, seat-swapped: reward_mean 1.0, reward_min 1.0, reward_max 1.0, seat1_reward_mean 1.0, seat2_reward_mean 1.0. |
