The standalone Core image SHALL boot a complete node from a single docker run with only a published port and a named data volume (Dockerfile targets railway-core/platform-core): PDPPREFERENCEORIGIN SHALL default to http://localhost:3000 and PDPPDBPATH SHALL default to /var/lib/pdpp/pdpp.sqlite so SQLite storage and generated credentials land on the mounted data volume. Managed platforms override both per deploy.
