Local Postgres, peer-authed over the unix socket (the "zitadel" role is granted createdb+createrole and doubles as both the runtime and bootstrap DB user - no password anywhere). TLS terminates at Caddy; Zitadel listens on localhost:8080 and is proxied at auth.mgaction.town. Master key and admin bootstrap password come from sops - the admin password specifically needs the sops.templates -> rendered-file route (services.zitadel.steps would leak it into the world-readable Nix store), same pattern as mercury's pihole.env.
