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. ## Regression Record | Revision | Change | Scenario | Why | |---|---|---|---| | 1 | initial | all | Establish the feature’s combined outcomes from the pinned specification and executable evidence. |
