# Immutable reconciliation activity

## Verification Boundary

This suite calls production services over the real test database. Fixture setup may write records directly; the exercised commands and queries retain their normal database enforcement.

## 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.
