+Three **Application** resources (sync waves **0 → 1 → 2**):
+
+| Wave | Application | Purpose |
+|------|-------------|---------|
+| 0 | `eclipse-che-devworkspace` | [DevWorkspace operator](https://github.com/devfile/devworkspace-operator) **v0.33.0** (`devworkspace/kustomization.yaml` → remote `combined.yaml`) |
+| 1 | `eclipse-che-operator` | [Eclipse Che Helm chart](https://artifacthub.io/packages/helm/eclipse-che/eclipse-che) **7.116.0** (operator in **`eclipse-che`**) |
+| 2 | `eclipse-che-cluster` | **`CheCluster`** (`checluster.yaml`) — Traefik + **cert-manager** TLS |
+
+**Prerequisites (cluster):** **cert-manager** + **Traefik** (noble bootstrap). **DNS:** `che.apps.noble.lab.pcenicni.dev` → Traefik LB (edit **`checluster.yaml`** if your domain differs).
+
+**First sync:** Wave ordering applies to **Application** CRs under **noble-root**; if the operator starts before DevWorkspace is ready, **Refresh**/**Sync** the child apps once. See [Eclipse Che on Kubernetes](https://eclipse.dev/che/docs/stable/administration-guide/installing-che-on-kubernetes/).
+
+**URL:** `kubectl get checluster eclipse-che -n eclipse-che -o jsonpath='{.status.cheURL}{"\n"}'` after **Phase** is **Active**.
