The on-cluster cluster-vars ConfigMap wasn't reconciled by Flux — this bootstrap
model had no Kustomization watching clusters/dev, so cluster-vars/overlay changes
needed a manual 'kubectl apply -k clusters/dev' (e.g. DNS_ZONE substituted empty
until re-applied). Add clusters/dev/sync.yaml: a self-managing root Kustomization
(flux2 gotk-sync pattern, name flux-system) that reconciles ./clusters/dev from git
— cluster-vars, the GitRepository, platform/platform-config/apps, and itself. A git
push now suffices. Bootstrap unchanged ('kubectl apply -k clusters/dev' creates it
once). Verified: dev build contains all 6 objects (root + existing), prod unaffected.

# clusters/dev — the ACTIVE build target overlay.

#
|
|
# `flux bootstrap ... --path=clusters/dev` points the dev cluster's Flux here. It reuses the base
|
|
# reconciliation graph and patches the shared cluster-vars ConfigMap with dev-scoped values (R-ENV-02).
|
|
# It also adds a self-managing ROOT Kustomization (sync.yaml) so the whole graph reconciles from git
|
|
# on every push — no more manual `kubectl apply -k` for cluster-vars/overlay changes (F-OPS1).

# Realises the commented decryption TODOs in clusters/base and sets the real source URL.

# The `sops-age` Secret is created out-of-band (bootstrap/sops/install-age-key.sh) — name only.
