Selling configuration and confirmation persistence

Verification Boundary

The suite exercises real PostgreSQL and Accounting persistence or database functions with isolated local workspace fixtures.

What This Suite Proves

Product persistence validates and replaces selling settings, reads CRM and Platform references and tests local rollback around the doubled communications port.

What It Does Not Prove

Local execution does not prove deployed infrastructure, downstream purchase behavior, real domain extension completion or atomic remote-template recovery.

Real Dependencies and Test Doubles

PostgreSQL, transaction context, constraints, foreign keys and Accounting persistence are real. The test owns its workspace fixtures and clock. Platform communications or shared-template tables use local stand-ins; CRM reference tables are local test fixtures.

Must Not Be Doubled

Do not double PostgreSQL, row-level security, transaction boundaries, constraints or the persistence implementation when claiming these local guarantees.
