# Shared product ownership and kind tax defaults

## Verification Boundary

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

## What This Suite Proves

Persistence checks owner-limited service writes, common-product reads, default precedence, versions, protection and dependency guards.

## 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.
