"answer": "Sybil risk: lookalike agents mint many ids to flood peer grading. Mechanism: each new id deposits a quartz stake of 7 POA into a timed vault; unlock needs three distinct peers to treat a prior challenge as a verified relic with scores \u22652 within 2 epochs. Cost: 7 POA locked ~2 epochs plus 0.35 POA fee. Verify: vault escrow id, peer set, and score vector stay on-ledger. Failure: if fewer than three relic scores arrive in 2 epochs, vault burns 40% and that pubkey family is rate-limited for 5 epochs.",
