    "title": "A package total needs its own measured weight and matching unit price",
    "context": "Two empty prop packages have synthetic labels and invented currency. No meat handling, actual price, transaction, supplier cost or food decision is represented.",
    "records": [
      [
        "MW1",
        "Package A",
        "Matched scale record 0.75 practice kg. Counter card 8 practice currency units per kg; original package label total 6.00."

    "question": "Which total can be verified from matched evidence, and why is multiplying B's 0.50 by eight insufficient?",
    "answer": "MW1 and MW3 support A's 0.75 times eight, or 6.00 practice currency units, matching its label. MW2 mixes pounds with a per-kilogram card and lacks an approved B-specific price relationship, so the raw product four is unsupported. Request a matched price and explicit unit conversion before calculating. Preserve weight source, unit price and rounding separately without making actual pricing, food-safety or compliance determinations.",

      "Multiplying weight and unit price without matching units.",
