| 4 | PRODUCTION | Production Agent | Heat wave (MODERATE): CW supply at 36°C elevated. MAC aftercooler less effective. Compressor isentropic efficiency drops 1-3%. Cold-box ΔT widens, reboiler duty up. |
| 5 | TANKS | Tank Inventory Agent | Reducing load 80%→73% (actual cut 7 pts for MODERATE conditions). Heat: lower efficiency means same production costs more power. GOX/GAN/LOX/LIN rates drop ~9%. |
| 6 | DISPATCH | Dispatch Agent | Heat: higher ambient → boil-off up 15-20% on LOX/LIN/LAR. Tank levels drop faster. LOX at 60%, LIN at 62%, LAR at 46%. |

- Ambient 36°C → CW 36°C, MAC eff 81%
- heatwave: ambient temperature 36°C (MODERATE). Duration ~18h.
- 🧠 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
