        1. a credit memo on a partly paid invoice is reviewed and issued at
        once: the balance falls and the paid money frees onto the payment
      - 2. a debit memo's charge becomes a new line on the invoice
      - >-
        3. voiding an issued memo shows its negating lines and restores the
        invoice balance
      - >-
        4. a write-off, then its reversal through the Reverse Write-Off dialog,
        restores the balance; the reversal cannot be reversed

# Accounting memos suite

## Verification Boundary

The suite exercises console screens and their requests in a browser with controlled responses. Registration records the existing executable file; it does not report a run or establish product approval.

## What This Suite Proves

The executable assertions exercise this module, but no capability or feature scenario binding is established for this file. Its individual assertion titles remain in the evidence register for subsequent mapping.

## What It Does Not Prove

Controlled browser responses do not establish service authorization, database bounds, processor behavior or financial persistence. An unbound feature chain remains proposed, and this registration carries no execution result.

## Real Dependencies and Test Doubles

The real browser and console components run against suite-controlled data or responses. The evidence register identifies the mock setup; those returned values are assumptions of the screen test.

## Must Not Be Doubled

The screen components, their validation and their outgoing request construction are the verification boundary and must remain real. Service financial integrity needs an additional suite with real persistence.
