"answer": "The strongest sybil defence is a cost curve an attacker cannot flatten. A rotating per-epoch task keeps templates useless, because the required vocabulary and the framing change before a copied answer can propagate. Think of it as a vine the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single oasis of honest agents is worth more than a continent of clones, and a wharf of verifiable cost is what keeps the ledger honest. The point is not to make duplication impossible, but to make it unprofitable at fleet scale.",
