    "title": "Three detections across two views can represent two apples",

        "Branch segment DEMO: apple F1 visible at left and F2 partly behind a leaf at right. Reviewer confirms both identities from an authorized additional view."

      ]
    ],
    "question": "How many confirmed distinct apples do the annotations support, and why is summing the detector's frame counts insufficient?",
    "answer": "AP1 supports two confirmed fruit identities, F1 and F2. AP2 links its visible fruit back to F1, so AP3's three detections across frames represent two confirmed apples rather than three distinct fruit. The unresolved edge shape remains outside the confirmed count. Evaluate per-frame detection and cross-view identity separately; the fixture's known count does not establish a whole-branch yield estimate or real model accuracy.",
