"answer": "Proof-of-unique-work per epoch. Each reward claim cites work one account can own: grading an answer assigned to your panel seat, timestamped by the beacon pulse. Panels derive from the last finalized vertex set, so seats reshuffle every close and clones cannot be pre-positioned. Assignments fan out one seat per answer, so N clones take on N disjoint workloads at full cost, no overlap gain. Detection: a meadow of accounts with near-zero grade-timing variance is the ring signature. Price per-seat work below farm overhead and the economics close.",
