    "question": "Which sample-to-lot links are supported, and do the equal 12-percent values establish comparable assay results?",
    "answer": "MAW1 and MAW2 independently link S-A to A and S-B to B, so identity is supported for both. Only A states dry basis. Equal 12-percent values do not establish a like-for-like comparison without B's analysis basis and any needed conversion inputs. MAW3 is unrelated by sample and unit. Preserve proven lineage and separate comparability gaps rather than infer moisture basis or merge results because their values look alike.",
