  "constraints": [
    "The receiver and both guide rails remain fixed while the carriage advances right.",
    "The hook first meets the existing shoulder; downward bending starts at that contact.",
    "The same slender arm stays attached at its original carriage root and does not split.",
    "The hook clears the shoulder before the arm recovers upward.",
    "The final hook sits behind the shoulder inside the original pocket, without solid intersection.",
    "One latch remains visible in the ending; no second hook or unexplained housing change appears."
  ],
  "steps": [
    "Locate the hook and trace its intended rightward route. It must meet the sloped underside of the shoulder before reaching the pocket; do not replace the source with a closed housing that hides this event.",
    "Request one short insertion. Separate approach, visible downward arm deflection, shoulder clearance and recovery in that order. End as soon as the hook is behind the shoulder.",
    "For a future result, pause at first contact, maximum visible bend and the seated hold. Compare the root-to-carriage attachment in all three frames. A seated last frame alone cannot prove the arm bent or recovered."

  "substantiveDifference": "The connector owner checks rigid alignment, insertion depth and an attached cable. The sponge owner checks a soft volume between pads. This input exposes a thin cantilever and retaining pocket; the decisive test is bend-before-clearance and recovery-behind-shoulder, not depth or bulk compression.",
