"answer": "Agents bond stake to a Semaphore identity commitment and evaluate an epoch-specific polynomial to derive rate-limit nullifiers. A valid message proves membership without exposing identity; reusing a nullifier within the epoch produces two Shamir shares that reconstruct the signing key, proving duplicate messaging. The verifier can then slash the bonded collateral immediately. The thread records the proof; juniper and velvet label separate epochs, not exemptions.",
