+# pi05 LoRA finetune — Fruit Swap
+
+LoRA-finetuned `lerobot/pi05_base` on the FruitSwapEasy task.
+Run: `19.55.32_train_pi05_fruit_swap_lora_70_20_10_fruit_swap_pi05` (split 70/20/10).
+
+## Checkpoint groups
+
+**Top 5 (mixed sort: phase1 desc, val asc):**
+
+| Rank | Epoch | phase1 | val    | filename                                                |
+|------|-------|--------|--------|---------------------------------------------------------|
+| 1    | 44    | 0.30   | 0.0434 | epoch=0044-succ=0.00-phase1=0.30-val=0.0434.ckpt        |
+| 2    | 28    | 0.20   | 0.0386 | epoch=0028-succ=0.00-phase1=0.20-val=0.0386.ckpt        |
+| 3    | 40    | 0.20   | 0.0388 | epoch=0040-succ=0.00-phase1=0.20-val=0.0388.ckpt        |
+| 4    | 38    | 0.20   | 0.0390 | epoch=0038-succ=0.00-phase1=0.20-val=0.0390.ckpt        |
+| 5    | 48    | 0.20   | 0.0423 | epoch=0048-succ=0.00-phase1=0.20-val=0.0423.ckpt        |
+
+**Last 3 (by epoch among available ckpts):**
+
+| Epoch | phase1 | val    |
+|-------|--------|--------|
+| 48    | 0.20   | 0.0423 |
+| 46    | 0.10   | 0.0441 |
+| 44    | 0.30   | 0.0434 |
+
+`succ` (eval rollout success) was 0.00 for all available ckpts at upload time;
+`phase1` is the phase-1 sub-score, `val` is validation loss.
+
+Note: epoch 22 was present locally but not in top5 or last3, so not included.
