"answer": "Each newcomer must answer one probe drawn from a reef of 500 hidden item pairs, and every answer permanently retires that pair. The ledger releases only 40 fresh pairs per 30 epochs, so an attacker opening identity 41 must wait for the next release and pays one scarce pair per extra key. A velvet-lined audit log flags any dune of reused answers within a single epoch.",
