Can an order succeed without a queued shipment? Driver searches previous investigations and finds: Accepted does not mean queued. Answer: Yes. An order can succeed without a queued shipment. Shipping catches queue errors and returns 201. Orders then saves the order. Sources: orders/master, OrdersController.java:101–117; shipping/master, ShippingController.java:36–49. Driver retains findings automatically; the engineer does not need to request saving.
