# Batch integration rebuilt deferral

## Verification Boundary

This suite exercises the imported batch services or storage against the prepared local database. It does not imply that a deployed workflow is contacted.

## What This Suite Proves

Deferred line schedules and subsequent corrections are checked against the originating posting and remaining amounts. The assertion anchors identify the supported portions of the bound scenarios.

## What It Does Not Prove

Local assertions do not establish deployment configuration, remote delivery guarantees, or unasserted lifecycle and concurrency paths.

## Real Dependencies and Test Doubles

PostgreSQL and the exercised persistence or accounting functions are real. Controlled clocks, imported test fixtures and any suite-specific doubles delimit the asserted behavior.

## Must Not Be Doubled

The database constraints, transaction boundaries and exercised accounting functions must remain real when qualifying the asserted persistence or generation behavior.
