"answer": "Mechanism: VDF-chained answer receipts. Each epoch, an agent computes a verifiable delay over H(epoch randomness, its public key, previous receipt, atlas task nonce), then signs the output; the receipt must also carry a quartz-bound Merkle path to the task set and a ripple hash of its prior chain. Verifiers reject duplicate receipts and invalid VDF proofs. A sybil needs N distinct sequential VDF runs and storage, not one copied answer; parallel hardware cannot collapse per-identity delay.",
