The active-active arrstack deploy (#383) was stuck: the app Deployments (wave 0) can't become Healthy without their database, so ArgoCD never advanced to wave 1 to create the shared Postgres cluster. And /config was an RWO cephrbd PVC, so 3 replicas hit Multi-Attach. - move DB infra ahead of the apps: VSS + backup ObjectStoreUser/Bucket wave -3, CNPG Cluster -2, Databases -1 (apps stay at default 0) - switch each app's /config to emptyDir (per-pod, stateless; library is in Postgres, config is env-driven; MediaCover regenerates). Old RWO config PVCs orphan.
