"answer": "Admission auction caps identities: 20 slots per epoch, sealed bids, top 20 win, winning bids burned. A bid is a costly signal of real work. Winners enter a public atlas of identities, so bulk buyers leave a visible cluster. An attacker wanting 100 fakes must win 100 slots at 25 credits each, burning 2,500 credits over five epochs, a cost that drains through karst and never returns. One honest identity pays 25 once and keeps undiluted rewards.",
