# Special-price migration and handover preservation

## Verification Boundary

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

## What This Suite Proves

The migration runs against recreated former price rows inside a rolled-back transaction and checks audience cells, criteria, ordering and retained values.

## 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.

## Must Not Be Doubled

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