  "inputPolicy": "Upload only the clean first frame; diagram is for review.",
  "title": "Eyes first, head second: a small gaze-and-turn exercise",
  "description": "Use an original portrait to separate an eye movement from the head turn that follows, with checks for pupil direction, nose position and shoulder stability.",
  "goal": "Brief two modest actions in a readable order: the eyes glance toward frame left while the head stays forward, then the head follows slightly and pauses. Timing remains a requested visual sequence, not a verified model control.",
  "preparation": [
    "Use a clear portrait with both eyes, nose, jaw and shoulders visible. The supplied adult is fictional and the clean input has no gaze arrows.",
    "Choose frame left as the gaze destination, rather than “their left,” which can be confused with the viewer’s coordinate system.",
    "Keep lips closed and shoulders level. Avoid adding speech, a smile, blinking instructions or a camera orbit to this two-stage exercise.",
    "Use the diagram to distinguish pupil displacement from a changed nose angle. It is a review guide, not an eye-tracking measurement."
  ],
  "prompt": "Use the uploaded portrait as the first frame. Keep the camera and the adult’s shoulders still. First, the eyes make a small glance toward frame left while the nose and head remain facing forward. After that glance is visible, the head turns gently a short distance toward frame left to follow the gaze. Keep the same face, hairstyle and collar, with the mouth relaxed and closed. End in a quiet slightly turned pose. Do not add speech, a large body turn or a second glance in the opposite direction.",
  "steps": [
    {
      "title": "Name one screen direction",
      "body": "Write “frame left” in both action clauses. Check the opening pupils and nose as separate landmarks so the direction can be judged without guessing the adult’s anatomical left."
    },
    {
      "title": "Create an eye-only interval",
      "body": "Put the glance before the head follows. In review, find at least a visible interval in which pupil position changes while the nose direction remains close to the opening; do not invent a precise timecode in advance."
    },
    {
      "title": "Follow the head without moving the torso",
      "body": "Inspect the head turn for a changing nose profile and jaw outline, while the collar and shoulder line remain stable. Reject a shoulder swivel that replaces the requested head action."
    },
    {
      "title": "Review the settled gaze",
      "body": "Watch the final eyes and mouth, then replay the entire transition. Record whether the order was legible; a matching last pose alone cannot show that eyes led the action."
    }
  ],
  "acceptance": [
    "Both eyes remain coherent and point in a compatible direction.",
    "The pupils first glance toward frame left while the head remains forward.",
    "The head follows toward the same side after the glance is visible.",
    "The nose and jaw change angle without a new facial identity appearing.",
    "The shoulder line and collar stay close to their starting position.",
    "The mouth remains relaxed and does not form speech.",
    "The ending holds one slight turn without an opposite glance or return cycle."

  "troubleshooting": [
    {
      "symptom": "Eyes and head turn together",
      "change": "Change only the sequence clause to hold the head forward for a brief visible glance before it follows; keep movement amplitude and input unchanged."
    },
    {
      "symptom": "The pupils diverge or cross",
      "change": "Reduce only the glance amplitude. Compare both eyes during the eye-only interval before adding head detail."
    },
    {
      "symptom": "The whole torso rotates",
      "change": "Strengthen only the fixed shoulder-and-collar requirement, then check whether the nose can change angle without the clothing turning."
    }
  ],
  "ending": "Finish with a small settled turn and write whether the eye-leading sequence was observable. This practice does not establish a real person’s attention, emotion or intention.",
  "assetCaption": "Original illustrated practice input and separate observation diagram. These are authored teaching assets, not a MiniMax H3 output or a model-tested result."
