## Summary - Add `compensating-controls.yaml` tracking 9 named controls that justify suppressed security findings - Update all Prowler mutelist descriptions with `CC: <id>` references to named controls - Add `mise run review-compensating-controls` task — surfaces stalest control with all codebase references - Add [[review-compensating-controls]] how-to doc - Organize Prowler and Kingfisher reports into `YYYY-MM-DD` subdirectories ### Compensating controls | ID | Mitigates | |----|-----------| | `single-user-cluster` | Image cache abuse, RBAC breadth, system pod privileges | | `tailscale-network-isolation` | Profiling endpoints, weak TLS, debug ports | | `local-registry` | AlwaysPullImages gap | | `sso-gated-admin-tools` | ArgoCD wildcard RBAC | | `operator-managed-pods` | Tailscale proxy pod security settings | | `ephemeral-privileged-jobs` | Prowler hostPID exposure | | `trusted-ci-only` | Forgejo runner DinD | | `init-container-isolation` | Grafana root init container | | `observability-stack-audit` | Missing apiserver audit logging | ## Test plan - [ ] `mise run review-compensating-controls` shows table and references - [ ] `kubectl kustomize argocd/manifests/prowler/` renders correctly - [ ] Sync prowler and kingfisher, verify next scan writes to dated subdirectory - [ ] Grep for `CC:` in mutelist files — every muted finding should have at least one 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: #320
