As an auditor, I want material business and configuration changes attributable and retained so that posted history and decisions can be reconstructed.

Acceptance scenarios

Create/edit/status/post/unpost/reverse/approval/import/integration actions record actor, time, target, and outcome. Posted documents, reversals, external responses, and source links remain immutable or versioned. Retention and purge periods require explicit owner confirmation.
