Integration tests now run end-to-end against an FGA-capable server image (overridable via AUTHORIZER_IMAGE): they install a model and a tuple through the _fga_* admin API, then verify allow/deny, contextual tuples, positional batch results and object listing. On older images without the fga_* GraphQL surface the FGA assertions skip with a warning instead of failing. The node test client also sends an Origin header now, satisfying the server's CSRF same-origin enforcement on state-changing requests (browsers send it implicitly).
