 * Coverage for `WorkerRuntimeManager.describeRejection` — the

 * `resolveLocalUrl` returns null.
 *
 * The tunnel echoes the returned `code` + `message` (plus the original
 * path) into the 502 body so a Studio client reading the response can
 * tell exactly what the worker refused to do. This file pins the wire
 * shape so a future refactor doesn't silently change the body Studio
 * relies on.
