    Never doubled: the database, its constraints, the delivery policy or the

# reserved domain suppression

## Verification Boundary

This suite exercises the local services and prepared PostgreSQL database. API lifecycle cases use signed test contexts through the real route handler; they do not invoke the deployed gateway.

## What This Suite Proves

Its cases exercise withhold reserved-domain recipients everywhere.

The registered scenario bindings identify the assertions this executable file contributes. They retain individual test references so that a composite scenario does not become a claim of complete execution by one file.

## What It Does Not Prove

Local outcomes do not prove deployed queues, external provider acceptance, production credentials or complete browser behavior. No fresh execution or conformance result is claimed.

## Real Dependencies and Test Doubles

The communication fixtures use real PostgreSQL and module logic. Shared support records queue and transport calls and stores objects in memory; sender provisioning substitutes a provider identity store. Signed API contexts replace the authorizer key in API suites.

## Must Not Be Doubled

Database constraints, workspace policy, state guards and the service operation under test must remain real. Recording a provider or queue call must not replace the submission, claim or outcome logic being checked.
