Editorial draft available to read. Factual and language review is pending. Examples are illustrative.
Decision and method
Distinguish diagnostic records, events needed for replay and evidence of confirmed operations. Define purpose, access, duration and owner for each class under the approved retention process. One universal duration can retain unnecessary content too long while still losing information required to recover pending work or explain a disputed integration result.
Illustrative example
Illustrative example: detailed trial messages are retained for less time than the minimum references needed to recognize pending retries. When detail expires, an explainable state remains without complete message content. The policy also covers exported copies and support files so retention behavior remains consistent beyond the main application database.
Acceptance check
Simulate expiration using fictional data and review what can be reconstructed afterward. Check that pending operations retain information essential for their resolution. Accept when durations have a reason, exceptions have an owner and implementation matches the documented scope, including known copies and outputs rather than only the primary storage location.
Key takeaways
- Define retention by purpose and recovery needs within the already approved process.
