- backend selected by castle.yaml 'secrets:' block (env overrides); no file fallback in openbao mode (bootstrap token still read from file) - route direct-read secrets (public DNS token, supabase pw) through read_secret - OpenBaoBackend node_prefix: read <prefix>/<name> then shared <name>, so a shared vault serves per-node overrides (e.g. each node's postgres password) - tests updated (fallback removed, settings + node_prefix selection)
