Attribute key carrying the utterance id on a SPEAK_TOPIC text stream. The client (which initiates each utterance) stamps a monotonic id here; the worker echoes it on the matching TTS_TOPIC status packet (TtsDoneMessage / TtsErrorMessage) so the client can drop status for an utterance it has already barged past — a cancelled utterance’s late tts_done must not clear the client’s thinking fallback or move state, or the UI wedges in thinking.
