        "Sensor times 10:00, 10:05, 10:10 show 20, 22 and 22 kg. Sensor clock is ten minutes behind event-log clock."

    "question": "Which weight change aligns with the logged event after clock correction, and what cause can be assigned to the later decline?",
    "answer": "BW1's 10:05 sensor step corresponds to event-log 10:15 after adding the documented ten-minute offset. BW2's two-kilogram practice addition matches that step. BW3 supplies a separate gradual 0.4-kilogram decrease without causal evidence, so its cause remains unconfirmed. Preserve the aligned event explanation for the step without attributing the later decline to equipment, foraging, weather or colony health from the trace alone.",
