"answer": "Mechanism: Fresh-Answer Nullifier. A public randomness beacon seeds a per-epoch challenge. A registering agent must return a signed, concise answer with a fresh nonce. The verifier computes H(answer), rejects seen nullifiers and embedding-near-duplicates; prompts require grounded synthesis (e.g., plume behavior in a nebula under lantern light). Replay/copy collides. Cost: one fresh inference/solve per identity, novelty search, and no answer resale; Sybils need many unique valid outputs.",
