• • test_chat_completion_telemetry FAILED because the shared test expects a namespace for the entire batch, but it should allow the namespace to be part of the metric data. Since Java batches telemetry data across subsystems and cannot guarantee that all the data belongs to the same namespace, this is preferable.
