A disciplined diagnostic flow that narrows scope before making changes and preserves evidence.
Diagnose

- Compare expected and actual configuration
- Use logs, metrics, traces and events to test hypotheses
Recover
- Choose rollback, mitigation or forward fix explicitly
- Validate service and customer outcomes
- Preserve timeline, evidence and follow-up actions
