+
+SVD task arithmetic merge for Qwen2.5-VL-72B-Instruct surgical frame captioning.
+
+| Adapter | Weight | Rank | Data |
+|---|---|---|---|
+| captioner_voiceover_v1 | 0.40 | 16 | Surgeon-narrated ortho voiceover dataset — general captioning |
+| captioner_v2 | 0.60 | 32 | Targeted v2 dataset (793 train) — priority-tool pass for mallet, reamer, Bovie, saw |
+
+Merged to rank 32 (alpha=32, scale=1.0) via efficient thin-SVD task arithmetic.
+
+## Training Details
+- captioner_v2 best val_loss: 0.0963 (3 epochs)
+- Hardware: 4× NVIDIA H200, device_map=auto, bf16
+- LoRA targets: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
