migrate up|down|check|dump (1:1 nmg-ctl-Pattern, ruft internal/database Migrate/MigrateDown/ValidateMigrations/CopyEmbeddedMigrationsTo). initdb prüft pg_roles/pg_database und legt Role + DB idempotent via sudo -u postgres psql an, mit Identifier-Whitelist gegen Injection. postinst wirt die drei Schritte vor systemd-enable: migrate check (Pre-Flight ohne DB), initdb, migrate up (als edgeguard-User via Socket-Peer-Auth). cluster-join/promote/dump-config bleiben explizit Phase-3-Stubs.
