  "deployment_status": "NOT PUBLISHED - review master held in C:/TERRA/renders/slope_concepts_out\\debuttress",
  "source_record": "outreach concept 5 (receipts/mpm_outreach.json); original raw frames lost",

  "reading": "28 m rock wall buttressed by an ice wedge (rho 900); melt dose 5 K x 10 kPa/K softens the wedge, it flows off, the exposed face ravels - the paraglacial sequence",
  "honesty": "the receipt records 6 design iterations; the stable-without-wedge corridor is narrower than coarse-grid noise",
  "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",
  "timing_policy": "Per-frame presentation durations are graded for emphasis (holds on recorded failure frames and the final state); frame order and count unchanged, no interpolation. Presentation time is not simulation time; the in-frame 'sim t' clock is the recorded simulation time.",
  "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.",
