 * Guards a configuration rendering on resolved authority (D6).
 *
 * The two renderings — editable forms and file-mode definition lists — are
 * mutually exclusive answers to a question only the server can settle, so
 * neither is drawn until it has. Pending is a skeleton; a failed status query
 * is an error with a Retry, never a form drawn on a guess.
 *
 * Runtime actions do not pass through here. Pause, update now and reload
 * certificates work under every authority, so their pages render them beside
 * the gate rather than inside it.
