# Blank shipping configuration values

## Verification Boundary

This suite checks blank shipping configuration values with controlled inputs and recorded dependencies. Its entry points remain within the process.

## What This Suite Proves

The bound scenarios identify the assertions this suite contributes. Source anchors retain the exact test cases; where a capability scenario has several contributing suites, a single binding does not imply that every branch runs here.

## What It Does Not Prove

Controlled inputs do not establish database enforcement, deployed integration or browser behavior. A recorded call is evidence about the adapter contract rather than a remote operation.

## Real Dependencies and Test Doubles

The imported logic is real; test inputs and dependency responses are controlled.

## Must Not Be Doubled

Keep the imported production logic and its request construction real. Record dependency calls and refusals rather than replacing the behavior being asserted.
