# petrol-trained-v2 (top-scored consensus distillation)

Fine-tuned **YOLOv11s** trained from COCO init on **134 high-quality
challenges** — only those where the best public miner achieved
composite ≥ 0.65 on the real validator. Boxes from `candidate_gt/*.json`
used as labels (consensus from top-scoring miners).

- Final val mAP@0.5: **0.9337** (vs trained-v1's 0.7525)
- Architecture: YOLOv11s, 9.4M params, 21.6 GFLOPs
- ONNX FP16, **19.3 MB** (≤ 30 MB rule)
- 4 classes: petrol hose, petrol pump, price board, roof canopy

Training: 250-epoch budget, stopped at epoch 125 by patience.
Best checkpoint epoch 70 with AdamW, cosine LR, no mixup,
mosaic close-out at epoch 230.
