    "answer": "OE1 and OE2 consistently match drawing A to E1's right-side R1 target. OE3 conflicts between its visible LEFT label and RIGHT header, while the filename alone supplies no authorized resolution. Flag B's exact laterality discrepancy for reviewer confirmation rather than silently changing a field or assigning it to the right or left eye. The fixture evaluates source linkage, not vision, diagnosis or clinical image content.",
