## Specification

All invoices with aging, filterable. Surfaces the **gapless-numbering check** as a banner when a gap exists — many VAT regimes require a sequence, and a gap is an audit red flag.

## 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.
