This looks implemented on current main. Automated hermes-sweeper review found that PR #17704’s closed-websocket reconnect fix is already present, with regression coverage.

Evidence:

• gateway/platforms/qqbot/adapter.py:684 now checks self._ws.closed on entry to _read_events() and raises RuntimeError("WebSocket closed").
• gateway/platforms/qqbot/adapter.py:639 routes that exception through the existing reconnect path, including _mark_transport_disconnected(), pending-future failure handling, and _reconnect(backoff_idx).
• tests/gateway/test_qqbot.py:2210 covers the closed-but-present websocket case by setting adapter._ws = SimpleNamespace(closed=True) and asserting _read_events() raises.
• The implementation landed in 3eeca4613d618618093db416b564a2b9ef8dbe6a (fix(qqbot): stop 100% CPU spin when WebSocket is closed but not None (#31193, #31771) (#40574)).

Thanks for the original report and patch — this path is now covered on main.
