    "question": "Which views support F on C1, and can the similar crop or occluded view establish the same component finding?",
    "answer": "RII1's linked C1/LEFT views and reviewer annotation support F at region R on that training component. RII2 belongs to C2/RIGHT despite filename resemblance. RII3 identifies C1 but obscures the relevant region, so it supplies neither confirmation nor absence of F. Keep component, orientation and visibility together rather than transfer features across lookalikes or turn an unobservable region into a clean inspection result.",
