Database checks for Rate Versions.Queries

Verification Boundary

The suite checks module persistence or service behavior against prepared PostgreSQL with scoped records.

What This Suite Proves

A historical price remains readable unchanged. Combined bindings require every named suite; a component assertion alone does not establish the full experiment.

What It Does Not Prove

The suite does not establish browser behavior, deployed routing, live model quality or actual recipient inbox delivery.

Real Dependencies and Test Doubles

PostgreSQL, production persistence queries, row mapping and execution-context transactions are real. The suite owns its inserted records and uses controlled dates where timing matters; persistence statements are not doubled.

Must Not Be Doubled

Retain PostgreSQL constraints, transaction behavior and the production persistence or dispatcher path under test. A scripted provider must not replace accounting or authorization.
