## Summary - Adds automated node-level verification to `review-compliance-reports`: kubelet file perms/ownership, kubelet config args, etcd CA separation, RBAC cluster-admin bindings - Mutes the 14 MANUAL Prowler findings via new `manual-node-checks.yaml` mutelist file - New `node-config-automated-verification` compensating control documents the approach - Script fails loudly (red FAIL + verdict panel) if any check deviates from expected values ## Test plan - [x] `mise run review-compliance-reports` — all 12 node checks PASS - [x] Injected bad expected value (perms 400 vs actual 600) — FAIL rendered correctly - [x] Fixed colon-in-binding-name bug (kubeadm:cluster-admins) with tab-separated jsonpath - [ ] After merge: sync prowler mutelist ConfigMap and verify next scan shows 0 MANUAL findings ## Note Prowler coverage is minikube-indri only — ringtail/k3s is a known gap tracked separately. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: #335

# Node-level and RBAC checks that Prowler reports as MANUAL because it
|
|
# cannot evaluate them from inside a pod. Compensated by automated
|
|
# verification in `mise run review-compliance-reports`, which SSHes into
|
|
# the minikube node and checks each condition directly every week.
