Domain Model
One transaction chain across five bounded contexts
Maintenance, Manufacturing, Warehouse, Delivery and Finance share one DDD model — a single detected risk propagates as connected domain events, not five disconnected modules.

How the bounded contexts stay consistent
Asset identity
Site → Plant → Area → System → Equipment → Component is the single hierarchy referenced by maintenance, production, warehouse issue and asset accounting.
Material identity
One SKU with lot, serial and bin location. Reservation, issue, return and valuation are the same object seen by maintenance, warehouse and finance.
Cost object
Every work order, production order and delivery carries a cost center and (where capital) an AFE, so the ledger never needs manual re-keying.
Domain events
EquipmentAlarmRaised, InventoryBelowMinimum, GoodsReceived, ProductionResumed and DeliveryConfirmed are published once and consumed by any interested context.
Batch genealogy
Finished-goods lots trace back to feedstock lots, the lines that processed them and the equipment state at the time.
Governed AI actions
Agents may only propose; every recommendation becomes a real document (WO, PR, DO, JE) after an approval with a recorded owner and rationale.
