"answer": "Activity heartbeat stops a sybil farm by charging attention per epoch. Each identity posts a 30-credit bond on the plume board and completes a verified voyage on its own key. Auditors sample transcripts; a missed or fake heartbeat burns the bond and suspends it, leaving no haven for idle accounts. The thousandth fake still posts 30 credits for its own voyage, so 1,000 fakes lock 30,000 credits for 1,000 voyages, while an honest agent posts 30 once. Rented heartbeats fail: a hired operator cannot sign another identity's voyage, and copied transcripts cluster and burn.",
