Cascade — 13 agent steps

#	step	agent	detail
1	INJECTION	Injection Engine	LAR tank CV leak at NE-01
2	MPC_SOLVE	MPC Optimizer	tank_pressure_cv_leak: LAR vent valve stuck 24% open (MODERATE). Leak rate: 2.4 kg/s.
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	Vent valve 24% open — LAR vaporizes and escapes at 2.4 kg/s (8640 kg/h). Boiloff rate 2.5x normal. Tank pressure rising, PSV may lift if valve not isolated.
5	TANKS	Tank Inventory Agent	Reducing load 80%→77% (3% cut) to slow LAR production into leaking tank. At 77% load, LAR production drops from ~0.0 to ~0.0 kg/s. Less product entering leaking tank = less product lost.
6	DISPATCH	Dispatch Agent	LAR tank at 49% (55150 kg). Drain rate: 2.4 kg/s from vent + customer demand + boiloff. At this rate, tank reaches critical 15% in ~3.4h.
7	CUSTOMERS	Customer Impact Agent	🔀 GCN: Route optimization active — 52-feature node embeddings × learned edge weights. Blending 70% distance + 30% GCN-learned delivery outcome weights.
8	LOSS_MITIGATION	Loss Ledger	Emergency dispatch triggered via tank.overflow event — HUB agent routes trucks to load LAR and deliver to customers. Maintenance crew also dispatched for valve repair.
9	ECONOMICS	Economics Agent	During vent leak, LAR production is reduced AND inventory is draining. Customers with <2 days inventory are at stockout risk. Priority dispatch to P1 tier. Estimated 4 customers affected.
10	RECOVERY	Recovery Planner	💱 Procurement: Evaluating spot buy/sell — proactive purchase at <1.5d for P1/P2 customers at 2.5x markup (cheaper than 3x emergency). Spot sell if tanks >85% and demand low.
11	STEP_10	STEP_10	📉 L1: Primary Production Physical Balance — SENS detects abnormal boil-off, flags CV leak for inspection
12	STEP_11	STEP_11	Product loss: 2.4 kg/s x $0.50/kg=$4320/h lost to atmosphere. Load reduction: 80%→77%. Net impact: -$4331/h.
13	STEP_12	STEP_12	1) Valve isolation crew en route (ETA 30min). 2) Temporary clamp to reduce leak rate. 3) Full valve replacement takes 2-4h. 4) After repair: ramp load back to 80%, rebuild LAR inventory over 4-6h.
