    "answer": "ARQ2 makes 24 units the current issued D1 width under sheet S1 revision B. ARQ3 predates that issue and still shows A's 20-unit value. It is evidence of a model-to-drawing conflict, not a later override or proof of coordinated completion. D2's unchanged detail does not resolve D1. Cite sheet, element, revision and export basis separately without making an installation or code decision.",
