Closes the transition opened in merge 1 (63f98aa). `prune: true` is restored on the
`platform` Kustomization now that the ownership transfer is VERIFIED on the live cluster,
not merely expected:
13/13 Kustomizations Ready, `cilium` among them, at main@sha1:23aa2854
Namespace/kube-system label kustomize.toolkit.fluxcd.io/name = cilium
HelmRelease/cilium label ... = cilium
HelmRepository/cilium label ... = cilium
platform inventory: 0 entries matching kube-system__Namespace | kube-system_cilium_*
cilium inventory: exactly those three objects
Cilium pods UNCHANGED from the pre-merge baseline —
cilium-2f8h8 r=0 2026-09-01T05:55:27Z
cilium-425m8 r=1 2026-08-30T13:25:10Z
cilium-54cww r=0 2026-09-01T05:55:26Z
HelmRelease still v11
So the relabel deterministically preceded any prune, exactly as the revision-gated
dependsOn edge predicted, and the ownership move cost zero pod restarts.
The in-file comment now records the lesson rather than the temporary state: before moving
ANY platform/* component in future, check whether it is the sole declarer of a shared
Namespace. platform/cilium/namespace.yaml was the only declaration of Namespace/kube-system
under ./platform, which would have turned a component-scoped prune into
`delete namespace kube-system` — taking coredns, metrics-server, local-path and Cilium.

Serves: R-PLAT-01, R-GITOPS-01.
