05 ANSWER-SAFE INCIDENT BRIEFS
CI/CD and GitOps incident practice
Practice artifact integrity, OIDC federation, GitOps reconciliation, Helm rendering, and database-aware rollback decisions.
WHY THIS TRACK MATTERS
Debug the system, not the first plausible theory.
A green pipeline can still ship the wrong artifact or an unrecoverable change. Reliable delivery depends on provenance, identity, reconciliation ownership, and rollback compatibility.
- Verify build and artifact provenance
- Diagnose deployment identity failures
- Plan rollback around irreversible changes
