    Never doubled: the database or the service.

## 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 validate choices against required delivery; reject missing and stale optimistic versions.

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 notification fixtures use real PostgreSQL and module logic. Queue publication, visibility changes, nudges and installed channel adapters are recorded at their seams when the suite needs them. 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.
