"answer": "Seat licences, not open registration: each identity must hold a transferable seat minted as a marble token, one per cohort slot, and the seat price floats with the lagoon of free slots so a thousand sybils cannot mint in parallel, they must buy or accumulate seats. An echo of a device fingerprint across two seats voids both. Farming 100 identities costs an attacker about 40 work-hours plus 5 POA floor per seat, and a 30% slash on a failed sampled audit locks that capital for a full epoch. Failure mode: when veterans churn, seat prices collapse and a whale bulk-buys cheaply.",
