Deploy retrained breathing model (temporal-split-corrected dataset v2); optimal_threshold.json now uses the balanced prevalence-adjusted operating point (0.684) instead of leaky-test-set F1-optimal (0.133)
Fix: replace flawed yolo11m-seg@640 checkpoint (89 FP/80% recall at real inference settings) with a clean retrain under corrected checkpoint-selection code and corrected val labels. See inference_config.json for the calibrated conf/iou/max_det this checkpoint needs.
