Decisions cannot be explained without knowing which rule ran for which operation. Record policy versions, rollout times and rollback relationships.
Evaluation approach
Associate each version with its changes, rationale and distribution scope. Assess older-client compatibility.
Application example
When blocks rise over a week, investigate policy changes even if the application version stayed the same.
Limits and considerations
Keeping only the current policy can make historical decisions impossible to explain.
Explain historical decisions accurately
Store the active policy identifier with each event. Today's rule cannot explain yesterday's decision. Track who changed it, the affected scope and the rollback target.
Test older applications when the schema changes. Unknown fields and unsupported rules must not silently succeed. Versioning records decision behavior, not merely filenames.
Checks and decisions
- Attach versions to decisions
- Approve changes
- Retain previous definitions
Manage policy as a production asset with the same traceability as code.
