# Recommendations Tables Verification

## Verification Boundary

The suite calls the persistence, database or composed service layer against the integration database. It verifies committed rows and the refusals asserted by its cases.

## What This Suite Proves

The recommendations tables assertions contribute to the scenarios listed in the register. Each binding retains its exact source test anchor so a reviewer can distinguish an individual contribution from the complete scenario.

## What It Does Not Prove

The register records source inspection only. It establishes no run result, delivery qualification or Product approval.

## Real Dependencies and Test Doubles

PostgreSQL and the services called by the suite are real. External service ports, file storage and queues may use the fixtures declared by the suite and its support helpers.

## Must Not Be Doubled

Keep the asserted database constraints, transactions, service functions and execution contexts real. For API suites, preserve the dispatcher and permission enforcement.
