The hub's VMUser (vmauth.yaml) references simple-user-secret via passwordRef,
but the Secret was never added to the hub's manifests. Without this Secret,
the VM operator cannot reconcile the VMUser into the vmauth config, causing
ALL requests to fall through to the unauthorizedUser catch-all (vmsingle).
Result: Vector log shipping to VictoriaLogs was broken — vmauth routed
/insert/elasticsearch/_bulk to vmsingle instead of vlogs-victorialogs.
Hub defaultRules groups kubernetesSystemControllerManager, kubeScheduler, and
kubernetesSystemScheduler used wrong key 'enabled: false' — chart expects 'create: false'.
This caused KubeControllerManagerDown/KubeSchedulerDown to fire as false positives
because OTC CCE managed k8s does not expose control plane for scraping.
Dev local vmagent had empty externalLabels, so backup-alert rules evaluated by local
vmalert had no cluster_environment label on kube_job_status_failed metrics. Added
cluster_environment=dev to match what the vm-client-stack vmagent adds for hub shipping.
