root-07-m03-services-and-service-discovery — a new, full gold-standard-
pattern module: the Service/Endpoints/DNS request path, choosing the
right Service type. Lesson, demonstration (a Service with zero
Endpoints — the single fastest diagnostic check for this failure
class), knowledge check, guided exercise (ClusterIP vs. NodePort vs.
LoadBalancer for three real components), a real Lab
(expose-service-basics), and a reflection.
root-07-m04-ingress-networkpolicy-foundations — a new PARTIAL module:
Ingress and NetworkPolicy at the architectural level (the security-
control framing of NetworkPolicy is deliberately deferred to ROOT 09).
Lesson + knowledge check + real Labs (ingress-task, network-policy).

root-06-m02-deployments-scaling-updates — a new, full gold-standard-
pattern module: why Deployments/ReplicaSets exist, how a rolling update
actually progresses, and what rollback restores. Lesson, demonstration
(a healthy rollout vs. one stalled on ImagePullBackOff), knowledge
check, guided exercise (planning a safe rollout strategy), real Labs
(rolling-update-task, deployment-rollback), and a reflection.
root-06-m03-jobs-cronjobs-daemonsets — a new PARTIAL module: Jobs,
CronJobs, and DaemonSets as distinct workload shapes from a
Deployment's always-on model. Lesson + knowledge check + real Labs
(job-task, cronjob-task).

root-05-m00-kubernetes-mental-model — a new, full gold-standard-pattern
front-door module for ROOT 05: what Kubernetes solves, the desired-state
model, the control-plane/worker split, and Pods/Namespaces/labels
through kubectl. Lesson, demonstration (watching a Pod get replaced
after manual deletion), knowledge check, guided exercise (planning a
Namespace layout), a real Lab (namespaces-basics), and a reflection —
sequenced ahead of the existing bare kubectl-fluency lab bank.
