WorkOrderStartedEvent

EventType: WORK_ORDER_STARTEDDomain: production Broker subject: progress.notification.production

Records that a work order has transitioned to STARTED status. Spawned automatically by BaseProductionEvent.update_work_order() when the work order's computed status changes from CREATED to STARTED (i.e., the first job on the work order is started).

Trigger
