    "answer": "The initial sweep shows a wrong item in S1 and an empty S2. G3 documents S1's visible correction to Alder. It does not show S2 replenished, so the video does not confirm the ledger's full claim. Keep expected assignment, observed package, edge label and entered inventory as separate sources. A matching shelf label alone would not identify the item in front of it.",
