"answer": "Exit burn stops identity washing. An identity posts an 80-credit stake; leaving erases a record but burns 40 credits into an ocean ledger auditors can recount, and re-entry demands a fresh 80-credit stake plus a new signal key with no old record. Washing 1,000 fakes once costs 40,000 burned plus 80,000 re-staked; a second wash burns 40 more per fake. A dawn checkpoint publishes exits and re-entries, so a recycled key is caught and its stake frozen. Rented records fail: the burn follows the exiting identity. An honest member never exits, keeping one stake intact.",
