  "title": "One fruit-slice drop: keep the slice singular and land on the plate",
  "description": "Practice a single citrus-slice descent onto a visible plate. Check object count, first contact, slice thickness and the final resting position.",
  "goal": "Describe one low-height ingredient drop with one clear landing and a settled ending. The original still is a staged practice input; it does not demonstrate a tested H3 drop or physically measured impact.",
  "preparation": [
    "Use the supplied single orange slice above a plain plate, or your own permitted source with a clear gap between slice and plate. No knife or cutting action is part of this task.",
    "Keep the intended landing region visible and empty. A patterned plate or a pile of fruit can hide duplication and the first contact.",
    "Choose a short downward path with the slice face visible. Large spins expose a hidden back and complicate segment-pattern checks.",
    "Decide on a soft landing without a visible rebound. If real food behavior or exact material impact matters, use captured footage rather than treating this as simulation."
  ],
  "prompt": "Begin from the uploaded single orange slice suspended a short distance above the empty plate. The camera and plate remain still. The one slice descends straight down a short distance onto the open center of the plate, keeping its round outline, rind thickness and visible segment pattern coherent. It makes one clear gentle contact with the plate and comes to rest there without bouncing up, splitting or cloning. Keep the slice face largely visible during the fall. The plate remains intact and the slice does not pass through its surface. End on the single settled slice. No cutting, no extra fruit, no splash or added text.",
  "steps": [
    {
      "title": "Check the object count at the start",
      "body": "Count one rind outline and one segment pattern, and confirm a visible air gap above the plate. Remove extra ingredients from the input rather than relying on a negative list."

    {
      "title": "Write descent and rest together",
      "body": "Specify straight down, one contact, then rest. Avoid slow-motion explosion, dynamic toss or looping drop language that requests additional behaviors."
    },
    {
      "title": "Locate the first contact",
      "body": "Advance around the moment the lower rind reaches the plate. There should be no gap after rest, no penetration through the plate and no second slice replacing the falling one."
    },
    {
      "title": "Compare the food structure",
      "body": "Check rind thickness and segment arrangement before and after landing. If the slice becomes a wedge or spreads flat, reduce only the requested drop height and keep the final rest condition."
    }
  ],
  "acceptance": [
    "There is exactly one fruit slice at the start, during descent and at rest.",
    "The slice travels down toward the plate rather than sideways out of frame.",
    "The visible rind and segment layout remain coherent.",
    "The slice keeps plausible thickness instead of flattening into a painted disc.",
    "First contact occurs on the visible plate surface inside its rim.",
    "The slice neither penetrates the plate nor rebounds into a second landing.",
    "The final shot holds one resting slice and an unchanged plate."

      "symptom": "It bounces repeatedly",
      "change": "Change only the ending to one gentle contact and rest; remove elastic or looping motion language."
    }
  ],
  "ending": "Finish with one slice visibly supported inside the plate rim. Retain the frame immediately before contact and the first resting frame as evidence for the contact check.",
