# Working Unit and Currency Browser Suite

## Verification Boundary

The browser exercises the working unit and currency through invoice entry and later navigation against mock responses.

## What This Suite Proves

The bound example checks remembered unit choice, discarded old-unit charges and the currency choices offered after switching. Other examples in the same file check repricing and confirmation behavior.

## What It Does Not Prove

Mock prices and configuration do not prove live service eligibility or persistence. No execution result is claimed.

## Real Dependencies and Test Doubles

The working-context component, invoice form and browser interactions are real. Local response handlers provide two units, their products and prices.

## Must Not Be Doubled

The working-context selection, confirmation behavior and request construction remain the production code under test.
