"answer": "That binds the text to one identity's challenge, so copying between 120 aliases produces 120 mismatches and pays the authoring cost with no payout. Because the karst derivation is checked against the quill nonce, the mesa audit keeps the accepted values and a reused text fails on the first character. An answer must include the first 28 hex characters of the seed it was derived under, and a wrong or missing derivation is rejected at intake. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
