+# Turbovision Petrol Station Detection Miner
+
+YOLOv11s ONNX FP16 model with built-in NMS, fine-tuned on SAM3 pseudo-ground-truth
+for petrol-station object detection on Bittensor Subnet 44 (TurboVision).
+Uses horizontal-flip TTA with per-class hard NMS merge for higher recall.
+
+## Classes
+
+| cls_id | label |
+|---|---|
+| 0 | petrol hose |
+| 1 | petrol pump |
+| 2 | price board |
+| 3 | roof canopy |
+
+## Model details
+
+- Base: `yolo11s.pt` (Ultralytics) fine-tuned on 243 petrol challenge images
+  labelled by SAM3 at `output_prob_thresh=0.5` (matching the validator's pseudo-GT
+  pipeline).
+- Export: ONNX opset 13, FP16, NMS baked in, static imgsz=1280.
+- Size: 18.4 MB (<30 MB limit).
+- Inference: horizontal-flip TTA with per-class hard NMS merge (iou=0.45).
+- Per-class confidence thresholds (tuned by greedy grid search on 100 fresh
+  challenges vs real SAM3 pseudo-GT):
+  - petrol hose: 0.43
+  - petrol pump: 0.63
+  - price board: 0.37
+  - roof canopy: 0.41
+- Latency p95 on RTX 4090: ~2.1 s for a 30-frame batch (~70 ms/frame with TTA).
+
+## Target element
+
+`manak0/Detect-petrol-station-1-0`
+
+## Real-validator-simulated evaluation (100 fresh challenges, SAM3 GT @ 0.5)
+
+Scoring follows the validator's exact `_evaluate_detection_metrics_at_threshold`
+pipeline: global TP/FP aggregation across classes and images, IoU=0.5 matching,
+`false_positive = max(0, 1 - FPs_per_image / 10)`, composite = 0.65·mAP50 + 0.35·FP.

+
+## Tiebreak notes
+
+- Validator uses `winner-take-all` per element.
+- Tiebreak among similarly-scoring miners favours the earliest `last_commit_block`,
+  so commit once (when the model is finalised) and leave it in place.
