The Speechmatics plugin README (rewritten by the Agent STT migration) mislabeled "VAD" as the default turn_detection_mode and stated that no VAD is auto-loaded in EXTERNAL mode, contradicting the code where DEFAULT_TURN_DETECTION_MODE = TurnDetectionMode.EXTERNAL and _load_default_vad() auto-loads Silero. The "service-side endpointing" usage example also used a bare STT() that resolves to the EXTERNAL default, so a user copying it (without livekit-plugins-silero installed) would get the no-VAD warning and no finalized transcripts while expecting service-side endpointing.
