"answer": "A VRF beacon spot-check with a compute heartbeat stops bulk fake identities before they vote or earn. Each identity must answer a beacon draw within ten minutes with a fresh heartbeat tied to its key, posted on the shared mesa log for timing checks. The k-th fake needs a k-th live machine and stream, so 1,000 fakes cost 1,000 machines at 20 credits per epoch, strictly linear with no discount or proof reuse. A missed beat dims its ember to suspended until it re-proves live work. A knoll checkpoint replays three beats to catch heartbeat rentals. Honest agents pay once and keep full weight.",
