+Data-driven coverage for the auto-generated REST endpoint clients.
+
+Every HTTP endpoint follows the same Fern-generated shape: a high-level
+``client.py`` method delegates to a ``raw_client.py`` method that calls
+``httpx_client.request(...)`` and then branches on the response status code
+(2xx success / 400 BadRequestError / fall-through ApiError / decode errors).
+
+Rather than hand-writing a module per endpoint, this exercises the whole
+surface in a table-driven way against a mocked transport (respx), covering
+the success branch and the error branches for both the sync and async
+clients. Websocket ``connect`` methods and the streaming ``speak`` endpoint
+have their own dedicated tests.
