    "context": "A contributor constructs an original woven swatch with a repeated raised motif and a simulated discontinuity. The model labels visible evidence only.",
    "records": [
      [
        "T1",
        "Reference strip",
        "Raised horizontal bars recur every 40 mm; bar edges remain continuous."

        "At 95 mm a lifted strand interrupts an otherwise straight run; mark visible in both views."

        "At 120 mm one view is obscured by glare and there is no second view."

    "question": "Which locations should be labeled as expected texture, a visible discontinuity or unresolved?",
    "answer": "Label 80 mm expected texture using T1 and T2, and 95 mm a visible local discontinuity using T3. Leave 120 mm unresolved from T4 because glare removes the relevant evidence. This identifies what is visible without assigning root cause or a roll grade.",
