Payment Method Update Patterns
Default Method Review
A static default method review shows Visa 4242, Mastercard 5555, future invoices, and Review only status.
Program
Default method reviews should show the current method, proposed method, and billing scope before any default changes.

Label the default method review.

The section is labelled by its visible heading. Show current default row.

The current default is exact pinned data. Show new default and scope rows.

The new default and invoice scope are exact pinned data. Render review-only status.

The status badge says this is review only. Check default switch readback.

The check says the default switch is readable before billing settings change. Check default switch honesty.

Current method, new method, invoice scope, status, and no live default switch.
step flow
step(1) labels the source, step(2) shows the current default, step(3) shows new default and scope, step(4) shows review-only status, step(5) checks the default switch readback, and step(6) checks the honesty note.
default readback
The section heading names the default method review surface.
default rows
Current default, New default, Applies to, and Status values are exact pinned data.
no live default switch
The lesson should not imply default payment changes, payment processors, billing APIs, invoice mutations, card token changes, account updates, storage, routes, APIs, networks, scripts, form submits, analytics, timers, or live default switches.
