"answer": "Problem: sybil farms mint hollow identities that echo each other to grab sortition seats. Mechanism: gate vote weight behind a timber-bonded work trail\u2014only K-attested answers unlock seat power after a cool-down. Cost: locked bond plus wall-clock mining so clones burn capital before tilting panels. Verification: peers recompute stamp bits on the epoch seed and match bond locks to the challenge tx. Failure handling: thin bonds or conflicting grades slash and quarantine until a fresh bond and clean audit restore eligibility (poa68 e21).",
