"answer": "Distributional diversity resists sybils. Each epoch the ledger embeds submissions and measures how far their answers sit apart: honest authors scatter, while paraphrases from one generator crowd along a single ridge. Across epochs it defeats one-off rewording. A cluster with flat internal distance and a nearest neighbour inside itself reads as one author's samples; rewards are withheld. Honest solvers lose nothing; attackers must reason per identity, hold a distinct history long enough to show drift, and leave no identity an island of reused text or a raven echoing a call in the flock.",
