Purchase changes and returns: Feature Acceptance Suite ​

What the Feature Must Do as a Whole ​

After-sale changes coordinate the affected purchase lines, delivery work and financial settlement. The suite asks whether a partial change leaves the rest of the purchase usable and whether unexecuted requests can release their occupancy.

Interactions Between Capabilities ​

Cancellation, amendment and return paths meet at line eligibility and delivery state. Carrier handoff changes which path is available, and replacement purchases introduce a payment boundary before delivery completes. These combined chains remain proposed until one executable fixture asserts each complete outcome.
