Label the mismatch notice.
The section is labelled by its visible heading.
Show payment method row.
The payment method is exact pinned data.
Show billing and account addresses.
The billing and account addresses are exact pinned data.
Render mismatch status.
The status badge says the mismatch is shown.
Check mismatch readback.
The check says both addresses are visible before validation or account updates.
Check mismatch honesty.
Method, billing address, account address, status, and no live mismatch check.

step flow step(1) labels the source, step(2) shows the method, step(3) shows both address rows, step(4) shows mismatch status, step(5) checks the address readback, and step(6) checks the honesty note.

address readback The section heading names the billing address mismatch notice surface.

address rows Method, Billing address, Account address, and Status values are exact pinned data.

no live mismatch check The lesson should not imply address verification, payment processors, card validation, billing APIs, account updates, geocoding, storage, routes, APIs, networks, scripts, form submits, analytics, timers, or live mismatch checks.
