    "question": "What variance is documented in the first count, and what is missing from a second-view-only recount?",
    "answer": "FWS1 and FWS2 both total six, and the size-seven quantity stays two. Within size eight, W1 is short one and W2 is over one relative to the plan, even though its total size-eight count stays four. FWS3 cannot independently establish that width distribution without the hidden label. Preserve size and width together and request a matching view rather than accept a total-only recount or infer real fit from the labels.",
