k3d registry containers are addressed as k3d-NAME.localhost:PORT from
inside the cluster, but containerd resolves that as 127.0.0.1 (loopback)
which has nothing listening. The fix is to write /etc/rancher/k3s/registries.yaml
on every server/agent node to mirror k3d-NAME.localhost:PORT -> http://k3d-NAME:PORT
(Docker network DNS), then restart the node so containerd picks it up.
_patch_k3d_registry_mirrors() is called from _ensure_k3d_registry() after
the registry is confirmed running (idempotent — skips nodes already configured).
This makes knoe-authority and any other image pushed to localhost:5000
immediately pullable inside the cluster as k3d-knoe-registry.localhost:5000/...

k3d-prole-registry was squatting on port 5000, leaving k3d-knoe-registry
in created state. Two bugs made this invisible:
- k3d_registry.py: substring match (name in stdout) matched k3d-knoe-registry
as already-exists without checking STATUS=running; add _k3d_registry_running()
requiring last column == running, detect and delete prole-registry before
creating knoe-registry, recreate if found in non-running state
- status_common_services.sh: grep -qx 'knoe-registry' (exact) never matched
k3d prefix 'k3d-knoe-registry'; fix with awk suffix match + STATUS==running

UI screens
- database.py: fix mode detection to use env_key priority (prod→k8s, service→k3s) so stale DEPLOYMENT_MODE never overrides the user's chosen environment
- database.py: Registry status reads ARTIFACT_REGISTRY_AVAILABLE persisted by cluster screen; uses SERVICE_NAMESPACE for Artifact Registry repo name
- cluster.py: add Artifact Registry traffic light (amber→green/red) to prod section; _check_artifact_registry_async persists ARTIFACT_REGISTRY_AVAILABLE into Global cfg
- cluster.py: re-trigger Artifact Registry check after GKE cluster selection so the light re-evaluates once region is available from KUBECONTEXT
- cluster_nodes.py: fix TclError on Python 3.14 — pady=(2,0) tuple → pady=2 scalar
- __init__.py: seed knoe-system namespace when saved value is "default", not only when empty
- services.py: replace hardcoded "Prole DB" log string with dynamic cnpg_cluster name
Core ops
- cloudnative_pg.py: replace one-shot Barman plugin retry with 6-attempt loop; first cert-manager/x509 failure triggers rollout restart + 30 s CA propagation wait; subsequent failures back off up to 60 s per attempt
- cloudnative_pg.py: TLS CA CN now uses cluster_name instead of hardcoded "Prole CNPG CA"
- registry.py, garage_store.py: refactored into per-mode modules (k3d/k3s/k8s registry and garage store, shared _garage_common)
Deploy / config
- deploy/gcp/gke/knoe-db.yaml: GKE-specific CNPG cluster manifest (rw/ro/r on separate nodes with premium-rwo storage)
- etc/init_common_services.sh, modes/k8s/knoe-db/.version: updated for current deploy
- kong-deployment.yaml: updated manifest
Tests
- test_cluster_nodes_render_smoke.py: add pack/grid, winfo_children, winfo_reqheight, update_idletasks, grid_slaves to dummy widgets; monkeypatch tk.Label so CNPG placement render completes without a real Tkinter root
