訓練日期 2026-05-21 · 5090-2 單卡 batch 96 · MobileNetV3-L + EMA + camaug
🟰 結論：持平 v518（+0.0001 mAP），新場域 RAI_11F 加入
cvat #2 自 v518 訓練後新通過 10 個 task / 197 frame（全部 RAI_11F_CH00 新場域）。best_val_mAP 0.9828 vs v518 0.9827，整體量級增加 0.06% 對 mAP 影響微小，但對 RAI 11F 場域 generalization 應有助。Early stop @ ep12（patience 4），best @ ep8 EMA。
