Raw effects

  2. heatwave: ambient temperature 36°C (MODERATE). Duration ~18h.
  3. 🧠 qwen3.5:9b (conf 75%): The active injection ‘trailer_boiloff_valve_leak’ on Truck T-E06 indicates a significant product loss of 50 kg/h (600kg/12h), marking the unit for maintenance. While the MPC optimizer suggests increasing load to 83% to offset economic losses from this leak, the plant physics rules strictly prohibit increasing load when any tank risks overflow. Current net flows show LOX is balanced (-0.01 kg/s), but LIN is filling (+0.33 kg/s). Increasing load further would exacerbate LIN accumulation. Given the cold ambient of -3°C and chilled CW (-1°C), efficiency is high, but we cannot override the ‘no over
