## Specification

> The fraud-prevention surface. Vendor-impersonation attacks work by changing bank details before a large payment, and the UI is the last line of defense.

A bank detail change within N days of a scheduled payment is flagged, requires out-of-band re-verification, and appears prominently in the payment run preview with the old and new details side by side and the change's actor and timestamp.

## Rules this component obeys

Money is minor units, never floats. `null` is not `0` and neither is redacted. Negatives render in accounting parentheses with the parenthesis column reserved on both sides. Debit and credit are two columns. Per-currency decimal places. Polarity is explicit — up is not always good. Every figure states its period, entity, currency, basis and as-of.
