# Data job queue

## Verification Boundary

This suite checks data job queue with controlled inputs and recorded dependencies. Its entry points remain within the process.

## What This Suite Proves

The suite’s source cases exercise the registered boundary, but this back-fill does not map them to a complete capability or feature scenario. The executable record remains useful without an invented scenario binding.

## 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. Queue publication uses the suite’s recording or scripted publisher.

## 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.
