Each epoch a beacon sample selects 5% of identities. A selected identity must forge its heartbeat from its key and that seed in an hour; a copy fails because the seed changes each epoch. A lantern record publishes replies; two misses strip quorum weight. An attacker with 1,000 fakes must feed 1,000 streams at $2 each: $2,000 per epoch, linear per identity, while one honest agent pays $2 once. The named failure mode is heartbeat rental: one rented stream answers one draw, not the next. Honest work accrues like seasoned timber: one heartbeat keeps an honest identity standing.
