#	step	agent	detail
1	INJECTION	Injection Engine	compressor_vibration: MAC vibration 3.6mm/s (ELEVATED), ISO 10816-3 zone B (acceptable). Zone thresholds: A≤2.3, B≤4.5, C≤7.1, D>7.1. Duration ~0.5h.
2	MPC_SOLVE	MPC Optimizer	🧠 qwen3.5:9b (conf 75%): Current MAC load is 80%, which is the maximum sustainable limit to avoid tank overflow. However, active injection ‘jt_valve_stiction’ has increased HP flooding to 83% (threshold 80%) and cause…
3	PHYSICS	Physics Kernel	📐 MPC: Optimal load 83% (4h horizon) | Priority: 3 | Expected margin: $0/h | Reason: All constraints healthy → optimize revenue (+load)
4	PRODUCTION	Production Agent	Vibration at 3.6mm/s indicates early-stage bearing wear or minor imbalance. MAC health=83%, surge margin 38% — healthy. Lundberg bearing L10 life ≈ 18820 h (baseline 40,000 h at 2.8 mm/s; life ∝ amplitude⁻³). At curre…
5	TANKS	Tank Inventory Agent	Reducing load 80%→74% (actual cut 6 pts, 6% intended). Power draw 21.4MW→~19.8MW. GOX/GAN/LOX/LIN mass flow drops ~8%.
6	DISPATCH	Dispatch Agent	LOX at 60%, LIN at 61%. At reduced load, tank fill rates drop ~8%. Tanks adequate for maintenance window.
7	CUSTOMERS	Customer Impact Agent	Normal dispatch continues. If maintenance extends beyond 2h, HUB agent accelerates dispatch. Drivers available: 4.
8	LOSS_MITIGATION	Loss Ledger	During load reduction, 8% less product. Customers with <2d inventory at risk of delayed delivery. Monitor SLA impact.
9	ECONOMICS	Economics Agent	📉 L1: Primary Production Physical Balance — PROC reduces load to maintain production continuity

Raw effects

0. MAC vib 3.6mm/s, health→90%, all tanks venting
1. compressor_vibration: MAC vibration 3.6mm/s (ELEVATED), ISO 10816-3 zone B (acceptable). Zone thresholds: A≤2.3, B≤4.5, C≤7.1, D>7.1. Duration ~0.5h.
2. 🧠 qwen3.5:9b (conf 75%): Current MAC load is 80%, which is the maximum sustainable limit to avoid tank overflow. However, active injection ‘jt_valve_stiction’ has increased HP flooding to 83% (threshold 80%) and caused unstable pressure control, while ‘trailer_boiloff_valve_leak’ indicates T-E01 losing 600kg over 12h (50kg/h) with boiloff valve leakage. The MPC optimizer suggests 75%, but given the 83% HP flooding and 5.0mm/s vibration (high risk for bearing failure), we must prioritize equipment safety. Reducing load to 72% drops HP flooding to ~78% and reduces vibration to safe levels (<4.5mm/s expected). This preve
3. 📐 MPC: Optimal load 83% (4h horizon) | Priority: 3 | Expected margin: $0/h | Reason: All constraints healthy → optimize revenue (+load)
4. Vibration at 3.6mm/s indicates early-stage bearing wear or minor imbalance. MAC health=83%, surge margin 38% — healthy. Lundberg bearing L10 life ≈ 18820 h (baseline 40,000 h at 2.8 mm/s; life ∝ amplitude⁻³). At current load 80%, centrifugal force amplifies the defect. Reducing rotor speed lowers vibration amplitude.
5. Reducing load 80%→74% (actual cut 6 pts, 6% intended). Power draw 21.4MW→~19.8MW. GOX/GAN/LOX/LIN mass flow drops ~8%.
6. LOX at 60%, LIN at 61%. At reduced load, tank fill rates drop ~8%. Tanks adequate for maintenance window.
7. Normal dispatch continues. If maintenance extends beyond 2h, HUB agent accelerates dispatch. Drivers available: 4.
8. During load reduction, 8% less product. Customers with <2d inventory at risk of delayed delivery. Monitor SLA impact.
9. 📉 L1: Primary Production Physical Balance — PROC reduces load to maintain production continuity
10. Cost of acting: revenue impact -$53/hfromreducedproduction.CostofNOTacting:MACtrip\to$57k/h total loss + 24h restart. Maintenance cost pays for itself vs trip risk. maintenance(mac) dispatched — ETA 60 min.
11. 1. Maintenance crew dispatched (1 millwright + 1 vibration analyst, ETA 60 min) for MAC bearing inspection. 2) At 74% load, vibration should drop to ~3.1mm/s (amplitude ∝ ω²). 3) After maintenance: health→100%, ramp back to 80% over 30 min. 4) Vibration analyst signs off at <2.5 mm/s. Expected total recovery: 1-2h.
