  # Raised by stream_events when meaningful (non-`server.*`) events stop
  # arriving for longer than the caller's `idle_stream_timeout` window,
  # even though the SSE socket itself is still alive (heartbeats are
  # still flowing). Distinct from StaleSessionError, which fires when
  # the session never produced any events in the first place. This one
  # fires when the session WAS producing events and then went silent —
  # the classic "OpenAI stream wedged mid-turn while the SSE keep-
  # alive ticks on" failure mode.
