 * That is ALL a transport needs: the express layer reads the api's @ApiPath/@Endpoint decorators
 * to bind each method's HTTP route to the matching `client` method — one-to-one with a test call
 * `client.method(dto)`. The proxy forms the RouteMetadata and drives it through the filters, so
 * the internal RouteBuilder never leaks out. Data-only structure (a class, per the guidelines).
