Implement a manual approval gate for production deployment in pipeline-as-code

This evaluates embedding human governance into immutable pipeline definitions without shadow processes or audit gaps. A strong response defines approval as code via environment protection rules or stage gates, binds identities with RBAC, sets timeouts and escalation paths, preserves immutable logs, and pairs the gate with automated rollback or fast-forward strategies for failure recovery. Red flag: Describing a process where someone manually runs CLI commands locally or bypasses version-controlled pipeline logic entirely.
