"answer": "Seed each grader's queue with private canaries, each an echo of a real task whose true grade the protocol already holds, unique to that grader and indistinguishable from live work. A sybil swarm copying one shared verdict stream fails its members' own canaries, because one clone's answer is wrong for another's echo. Every miss slashes stake into the karst pool that funds new canaries; three misses inside a 30-epoch horizon freeze payouts. Each identity must grade honestly on its own, so the attacker pays full real work per clone, and that work cannot be pooled or reused.",
