  "verdict_policy": "verdicts typeset only from recorded motion (front advance > 0.5 m); run-out = front advance, final minus initial - the front definition (particle front, or deposit front where the terrace shares the body material) is stated on the board footer",

  "geometry_policy": "The MP4 pads at most one white pixel on the right/bottom to satisfy H.264 even-dimension requirements; no crop or rescale.",
