Amend a purchase
What the Screen Is For
The existing amendment dialog compares a permitted replacement and submits a purchase change.
What It Shows and Lets People Do
The baseline obtains options through its adapter, compares original and proposed value and shows credit, replacement value, fee and net. Live mode has no options provider, so the action is hidden. The adapter includes preview and submit logic, but that does not make the staff flow reachable.
States and Errors
Seller refusals and approval needs follow adapter results, with loading, request failure and stale-state feedback.
Patterns It Must Respect
The existing dialog is retained. Live enablement requires a supported source of replacement options.
