Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The target Role is missing permission to watch ConfigMaps and Secrets, which can cause shutdown cleanup to miss build objects and leave them orphaned. The change is otherwise mergeable with owner awareness, but the permission should be added before merge. 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 inconclusive)

Full details: Docstring CoverageExplanation No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files. (1 skipped: 1 unsupported.) Full details: Stable And Deterministic Test NamesExplanation The custom check requires stable and deterministic Ginkgo test names without dynamic information. Investigation shows: Findings: 1. The pull request modifies 4 files total: - manifests/machineosbuilder/clusterrole.yaml (YAML RBAC resource) - manifests/machineosbuilder/configmaps-secrets-role-target.yaml (new YAML RBAC resource) - manifests/machineosbuilder/configmaps-secrets-rolebinding-target.yaml (new YAML RBAC resource) - pkg/operator/sync.go (Go code to sync manifests) 2. No test files were modified or created in any of the commits (a6534cd, 49c6b07, fe01940). 3. No Ginkgo test definitions (It(), Describe(), Context(), When(), etc.) were added in any of the changed files. Conclusion: This pull request does not introduce any Ginkgo tests, so the custom check is not applicable. The changes are purely RBAC manifest updates and Go code modifications to sync those manifests, with no test-related changes. Full details: Test Structure And QualityExplanation PASS: The pull request changes only three YAML manifests and Full details: Microshift Test CompatibilityExplanation PASS: The pull request changes only Machine OS Builder RBAC manifests and Full details: Single Node Openshift (Sno) Test CompatibilityExplanation The custom check "Single Node OpenShift (SNO) Test Compatibility" applies only when new Ginkgo e2e tests are added to the codebase (tests containing It(), Describe(), Context(), When(), or similar Ginkgo constructs). This pull request contains only the following changes: 1. manifests/machineosbuilder/clusterrole.yaml - YAML ClusterRole manifest (RBAC narrowing of permissions) 2. manifests/machineosbuilder/configmaps-secrets-role-target.yaml - New YAML Role manifest for ConfigMap/Secret access 3. manifests/machineosbuilder/configmaps-secrets-rolebinding-target.yaml - New YAML RoleBinding manifest 4. pkg/operator/sync.go - Go source code modifications (operator implementation, not test code) No Ginkgo e2e tests are added or modified in this pull request. All changes are Kubernetes manifest configurations and operator code. Therefore, the SNO test compatibility check is not applicable to this pull request. Full details: Topology-Aware Scheduling CompatibilityExplanation The pull request changes are exclusively RBAC modifications (Roles, RoleBindings, ClusterRoles, and operator code to apply them). The existing deployment.yaml for machine-os-builder contains no scheduling constraints that assume standard HA topology (3+ control-plane nodes and dedicated workers). Specifically: replicas is set to 1 (appropriate for non-HA); no pod affinity rules; no pod topology spread constraints; no PodDisruptionBudgets; no nodeSelectors targeting control-plane only; tolerations for control-plane taints are permissive, not restrictive; no strategy with maxUnavailable: 0. These changes introduce no topology-incompatible scheduling behavior. Full details: Ote Binary Stdout ContractExplanation The pull request modifies Kubernetes manifest files and Full details: Ipv6 And Disconnected Network Test CompatibilityExplanation The custom check applies only when new Ginkgo e2e tests are added. This pull request modifies Kubernetes RBAC manifests and operator sync code only: - manifests/machineosbuilder/clusterrole.yaml (narrowed permissions) - manifests/machineosbuilder/configmaps-secrets-role-target.yaml (new) - manifests/machineosbuilder/configmaps-secrets-rolebinding-target.yaml (new) - pkg/operator/sync.go (manifest path definitions) No e2e test files, Ginkgo test patterns (It(), Describe(), Context(), When()), or test-related code are introduced. The check is inapplicable to this pull request. Full details: No-Weak-CryptoExplanation This pull request introduces changes exclusively to Kubernetes RBAC manifest files and manifest-reference constants in Go code. The changed files are: 1. Full details: Container-PrivilegesExplanation The pull request modifies RBAC manifests (ClusterRole, Role, RoleBinding) and updates operator sync logic. A comprehensive check of all modified files and related container specifications confirms no container privilege escalation concerns were introduced. The Deployment manifest contains no Full details: No-Sensitive-Data-In-LogsExplanation The pull request introduces only RBAC (Role-Based Access Control) manifest changes and related code constants. The changes consist of: 1. Manifest modifications: Updated

ClusterRole binding to a namespace-scoped Role and RoleBinding in
ctrlcommon.MCONamespace, preserving get, list, create, update, and delete access
for machine-os-builder. Keep ConfigMap permissions scoped as currently required
and ensure the service account no longer has Secret access outside the MCO
namespace.
