config/rbac/kustomization.yaml:1

• The comment states leader-election RBAC is 'intentionally disabled' and that 'the production deployment does not enable --leader-elect', but the rendered Deployment in manifests/setup/setup.yaml (and config/manager/manager.yaml) passes --leader-elect, and these two leader-election resources are actively included (not commented out). Either remove the contradictory comment or rewrite it to reflect that leader-election RBAC is enabled to match the manager args.
  tests/scripts/fluentd_e2e.sh:1
• Using a literal \\n in the sed replacement to inject a new imagePullPolicy: line is a GNU sed extension; BSD/macOS sed will emit a literal n instead of a newline and produce invalid YAML, breaking the script for developers running e2e locally on macOS. Consider either using two separate sed expressions where the second uses a\\ to append a line, piping through awk, or constructing the multi-line replacement using a literal newline inside the shell string ($'\\n'). At minimum, document the GNU-sed dependency.
  manifests/setup/setup.yaml:1
• The manager is started with --metrics-bind-address=:8443 but the container declares no containerPort for 8443 and the metrics Service / NetworkPolicy / ServiceMonitor sections in config/default/kustomization.yaml are all commented out. The metrics endpoint will therefore be unreachable from outside the pod. If metrics aren't intended to be exposed in the default bundle, consider setting --metrics-bind-address=0 (disabled) to avoid binding an unused port; if they are intended, expose the port and enable the metrics Service.
  manifests/setup/setup.yaml:1
• readOnlyRootFilesystem: true is set, but the manager binary currently writes leader-election cache files (controller-runtime writes to its temp dir) and may rely on /tmp. Without an emptyDir mount at /tmp (only the env configmap is mounted under /fluent-operator), the pod can fail to acquire the leader lease or to perform any operation that touches the filesystem. Consider adding an emptyDir volume mounted at /tmp to keep the read-only root while preserving writable scratch space.
  config/rbac/role_binding.yaml:1
• The ServiceAccount subject no longer specifies a namespace. For a ClusterRoleBinding, the subject's namespace is required when kind: ServiceAccount; kustomize's namespace transformer does set it for ServiceAccount resources, but it does not by default rewrite subject namespaces inside (Cluster)RoleBindings unless configured to. Verify the rendered setup.yaml actually contains namespace: fluent under this subject (looking at the diff for setup.yaml, the ClusterRoleBinding still references namespace: fluent, so kustomize is handling it — please confirm this stays true if a consumer overrides the namespace in manifests/setup/kustomization.yaml).
  config/manager/manager.yaml:1
• Quoting ALL is unnecessary and inconsistent with the rendered manifests/setup/setup.yaml (which emits - ALL unquoted). Drop the quotes to keep source and generated forms identical and avoid spurious diffs on regeneration.
  controllers/fluentdconfig_controller.go:1
• The previous markers granted get;update;patch on fluentdconfigs/status and update on fluentdconfigs/finalizers. The new consolidated marker on line 90 covers */status but the /finalizers permission has been dropped entirely. If the controller still adds/removes finalizers on fluentdconfigs or clusterfluentdconfigs (the previous code did via the update verb on /finalizers), reconciliation will fail with a forbidden error. Please verify whether finalizer handling was removed; if not, restore a +kubebuilder:rbac:groups=fluentd.fluent.io,resources=clusterfluentdconfigs/finalizers;fluentdconfigs/finalizers,verbs=update marker.
  controllers/fluentbit_controller.go:1
• The marker core,resources=events,verbs=list;watch was removed here. If the controller's manager still records Events (controller-runtime's default event recorder calls create/patch on events) or any reconciler watches them, this will produce permission errors. The rendered ClusterRole in setup.yaml no longer grants events at all (only the new leader-election Role grants events: create;patch in the fluent namespace, which won't cover cluster-scoped consumers). Please confirm event recording still works at runtime, and if so, retain at least events,verbs=create;patch on the operator's ClusterRole or namespaced Role as appropriate.
  tests/scripts/fluentd_e2e.sh:1
• The VERSION variable (previously read from the VERSION file) was removed, but if other parts of this script or downstream tooling referenced $VERSION, those references will now be unbound. Please confirm nothing else in the file (not shown in the diff) still uses $VERSION.
  manifests/setup/setup.yaml:1
• The leader-election Role/RoleBinding are hard-coded to namespace: fluent. If a user customizes the install namespace via manifests/setup/kustomization.yaml (the comment in that file suggests doing so), this resource will be left in fluent while the Deployment moves to the new namespace, and leader election will fail with a forbidden error on leases. Confirm the kustomize namespace transformer rewrites these as expected, and document the requirement to regenerate (make manifests) after changing namespaces.

config/rbac/role_binding.yaml:15

• subjects for a ClusterRoleBinding that targets a ServiceAccount should include namespace. With it omitted, applying this YAML directly would bind to a ServiceAccount in an empty/unknown namespace (effectively granting no permissions). If you intend to rely on kustomize’s namespace transformer to inject it, consider making that explicit (or set namespace: fluent here) to avoid standalone usage pitfalls.

tests/scripts/fluentd_e2e.sh:83

• start_fluent_operator pipes manifests/setup/setup.yaml into kubectl create, but setup.yaml now contains a Namespace fluent manifest. Since the script also creates the namespace in prepare_cluster, this will fail with an AlreadyExists error (and abort due to errexit). Consider either removing the explicit namespace creation in prepare_cluster, switching this to kubectl apply, or filtering the Namespace document out of setup.yaml for the e2e path.
  config/rbac/role_binding.yaml:15
• This ClusterRoleBinding’s ServiceAccount subject is missing namespace. Without it, the manifest is invalid when applied directly (the API requires subjects[].namespace for ServiceAccount subjects). Add the namespace here (and let kustomize override it if needed) to keep the RBAC manifests self-contained and valid.
