# Read-only settlement holiday calendar constraints

## Verification Boundary

This suite exercises record constraints and database security using the application role and suite-owned fixtures. Direct writes isolate database enforcement from command behavior.

## What This Suite Proves

The executable assertions identified in the binding records supply the registered scenario observations. When a scenario names several suites, this suite supplies its listed assertions and does not independently establish every clause.

## What It Does Not Prove

Deployed infrastructure, live console behavior and shared scheduling delivery are outside this local boundary.

## Real Dependencies and Test Doubles

PostgreSQL, migrations and the exercised production code are real. Fixtures supply the financial world and caller context; deterministic setup and owner-side inspection do not replace database enforcement.

## Must Not Be Doubled

The exercised database constraints, transactional services and route enforcement remain real. Replacing them would remove the boundary this suite registers.
