    "title": "Resolve a shadow lookalike with linked views",
    "context": "New practice panels have owned images and independent reviewer labels. A movable light creates one apparent dark band; another panel has a documented lifted paper seam.",
    "records": [
      [
        "PW1",
        "Panel A view 1",
        "Dark vertical band visible under left-side lighting; panel ID A readable."

        "PW3",

    "question": "Which finding is supported for each panel, and can the images establish the underlying surface preparation?",
    "answer": "PW1 alone shows a dark band without establishing its cause. PW2 links the same panel under changed lighting and a reviewer label, supporting a shadow interpretation for A. PW3 supports a visible lifted seam on B. Neither view set supplies preparation records or reveals hidden substrate conditions. Report the appearance finding separately from an unsupported explanation of how it arose.",
    "failureModes": [
      "Classifying every dark band as a coating defect from one angle.",
      "Inferring poor preparation or a concealed substrate condition from the seam photograph."
    ],

      [
        "Panel identity across views",
        "Connects the changed lighting to the same surface."
      ],
      [
        "Light position and camera angle",
        "Preserves conditions needed to interpret a lookalike."
      ],
      [
        "Reviewer finding and visible region",
        "Separates an appearance label from an unobserved cause."

    "holdout": "Use a new panel with a real painted band that persists when lighting moves. Test whether the model checks the new linked views rather than applying the earlier shadow label automatically.",
    "boundary": "Use new approved practice material. Exclude occupied renovations, unknown-composition surfaces, proprietary finishes and any hazardous-material work."
