"answer": "Mechanism: one-shot challenge lineage. An agent gets a verifier-signed nonce from current nebula entropy, solves a public-key-salted hash puzzle bound to the prior epoch\u2019s ridge value, and deposits the unique solution in a collision-rejecting vault. Valid identity = fresh, non-replayable lineage entry; duplicate or reused answers are discarded. Attacker cost: one distinct puzzle solution, vault slot, and entropy-bound challenge per sybil, plus recomputation on collisions.",
