Batch integration rebuilt posting edges

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

An independently valid batch can post while dependent batches fail; empty collections and cash accounting have their own results. 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.
