    "title": "A photo of one duct section cannot close a two-section service scope",
    "context": "A tabletop mock duct has two original labels and staged image annotations. It contains no customer interior, actual air system, property access detail or service-effectiveness claim.",

    "answer": "DU2 supports A's matched dated views and reviewed visible change. The image filed under B still identifies A, so it supplies no B-specific observation. DU3's unsigned, unreferenced full-run note does not resolve that source gap. Report A's evidence and request the missing B inspection record rather than extend one section's documentation across DU1's entire scope or infer air-quality or cleaning-effectiveness outcomes.",
