    "answer": "LW1 supports A's net of 1,200 minus 900, or 300 kilograms, equivalent to 0.30 metric tonnes. LW2 lacks a matched B exit measurement, so its net cannot be verified by the B-old ticket from another date. LW3's 550-kilogram total includes that unsupported pairing. Preserve the supported A subtotal and B's missing measurement rather than present a complete daily total from unmatched records.",
