Correct CMP setup (prior attempt used unsupported config): repoServer.initContainers fetches sops v3.9.0 + yq v4.44.3 into a shared volume; repoServer.extraContainers runs argocd-cmp-server with plugin.yaml from the sops-cmp-plugin ConfigMap, age key from sops-age Secret. Plugin emits authentik/loki-s3-creds/grafana-admin/grafana-oidc Secrets from decrypted enc files. sops-secrets Application (wave 0) uses the plugin at repo root. Unblocks authentik/loki/grafana which were Degraded on missing secrets.
