    "answer": "WS1 and WS2 establish an identified visual observation of C-A associated with W1. WS3 still shows C-A even though it sits in W2's attachment set. Without a C-B observation or an authorized relationship correction, it does not establish W2's specified connection identity. Flag the mismatch and request the relevant view. None of the images supplies testing, concealed-condition or installation-approval evidence.",
