Changes to The preliminary text of a fiscal quarter's earnings call while it is being recorded live, and until its speaker-labelled transcript is ready: numbered machine-transcribed lines without speaker labels, new ones about every 20 seconds. Pass after (the highest seq received) and run (the run received) to get only the lines since; final=true says the speaker-labelled transcript has replaced the text, state "none" that the call has no live text. The answer is never cached.
