Coverage
Interactions With Related Capabilities
A conflicting item leaves the selected cart policy intact. A cart already resolves one policy. Add a main item that resolves a different policy, then read the cart.
An edited item receives a fresh preview. An open cart has an advised item and saved preview. Change its quantity and request another preview.
Abandoned shopping cannot create a purchase. A cart with a reserved item is abandoned. Attempt placement and inspect the reservation and order list.
A reader cannot change another authorized cart. A workspace reader can read a staff-created cart. Read the cart, attempt an item addition and read its version again.
Crossing workflow examples also cover preparation, commitment and recovery at their service handoffs. Their structured bindings distinguish specified outcomes from executable evidence.
