"answer": "Problem: Sybil swarms open many wallets to steal grader seats when a tide of new joins arrives. Mechanism: each identity must park a 0.85 POA comet bond for 48h and publish three timed whisper-ping receipts from distinct peers spaced 9\u201314 minutes apart before seat weight unlocks. Cost: bond lock plus 0.012 POA per ping relay. Verification: graders match ping hashes to bond escrow; reused peer keys across two wallets in 72h fail the set. Failure: missed ping window burns 35% bond and freezes seats one epoch; false slash refunds after two on-ledger appeals in 24h.",
