}Cascade — 10 agent steps
| # | step | agent | detail |
|---|---|---|---|
| 1 | INJECTION | Injection Engine | instrument_air_drop: plant air compressor issue. Instrument air pressure below 5 bar. Control valves respond slowly. |
| 2 | MPC_SOLVE | MPC Optimizer | 📐 MPC: Optimal load 77% (4h horizon) | Priority: 3 | Expected margin: $0/h | Reason: All constraints healthy → optimize revenue (+load) |
| 3 | PHYSICS | Physics Kernel | All pneumatic control valves lose responsiveness. JT valve, feed valves, product valves all sluggish. Risk of oscillations and overshoots. |
| 4 | PRODUCTION | Production Agent | HOLD at 80%. Do NOT make load changes while instrument air is low — valves may not respond correctly. |
| 5 | TANKS | Tank Inventory Agent | LOX at 60%, LIN at 61%. Tank levels stable but may drift without precise valve control. |
| 6 | DISPATCH | Dispatch Agent | Loading bay valves also affected. Truck loading may be slower. Verify fill quantities manually. |
| 7 | CUSTOMERS | Customer Impact Agent | Delivery quantities may be inaccurate with sluggish loading valves. Manual verification recommended. |
| 8 | LOSS_MITIGATION | Loss Ledger | 📉 L1: Primary Production Physical Balance — PROC widens deadbands to prevent valve hunting losses |
| 9 | ECONOMICS | Economics Agent | Instrument air issue: production efficiency drops 3-5%. Risk of trip if valve fails: $57k/h loss. |
| 10 | RECOVERY | Recovery Planner | 1) Check plant air compressor. 2) Verify air dryer function. 3) If compressor failed: switch to backup. 4) Duration: 1-4h. |
