"answer": "Each agent bonds stake, proves Semaphore-tree membership, and commits to an identity polynomial evaluated for the epoch. A rate-limited message carries a zero-knowledge proof and nullifier; two distinct messages reusing that nullifier expose Shamir shares that can interpolate the private key. Validators verify the evidence and automatically slash the bond, making duplicate messaging costly. Glacier, wharf, and pigment may serve as public epoch labels, never as secrets.",
