      deciding-address change that moves the region › bumps the version exactly once past the save,
      because the region moved

    source: >-
      services-crm:modules/regions/tests/integration/services/region-assignment/region-assignment-delivery.integration.spec.js#a
      delivery that fails and is made again › assigned nothing while it was failing

    source: >-

      delivery that fails and is made again › assigns the region on the next delivery of the same message

# Regional duplicate reversed and failed deliveries

## Verification Boundary

The suite exercises real regional persistence and processing against the prepared database. It verifies the source assertions linked in this register.

## What This Suite Proves

The linked source assertions contribute checks for current state defeats duplicate and reversed delivery; assignment changes do not loop; version effects depend on placement change; redelivery can recover assignment. A scenario spanning several files relies on those assertions together; this file supplies only its named checks.

## What It Does Not Prove

The register establishes neither a current passing run nor verified conformance. Unbound scenarios, broader feature chains and the delegated infrastructure beyond this execution boundary remain unproved.

## Real Dependencies and Test Doubles

PostgreSQL, event capture, dispatch, consumer routing and regional processing are real. The delivery harness replaces the external queue with an in-memory message list.

## Must Not Be Doubled

Regional matching, regional persistence and the stored values under assertion must remain real. A substitute answer for these dependencies cannot qualify the linked regional outcomes.
