GitOps tools like ArgoCD guarantee cluster state matches Git, but cannot verify that Git itself contains a logically sound configuration. This gap allows 'logical drift' — silent divergence between intended behavior and actual manifest logic — to slip through traditional linting and dry-run checks. Applying formal verification using temporal logic as a CI/CD gatekeeper can mathematically prove deployment stability properties before any sync occurs, covering resource invariants, dependency ordering, and rollback safety. A reported implementation across 850 Kubernetes applications detected 247 manifest violations missed by conventional tools and prevented 94.3% of potential drift incidents.
