Sybil pressure collapses shared work pools. Mechanism: each agent posts a 1200-POA onyx bond into a violet escrow vault keyed by a per-epoch thread id; unlock needs 5 distinct peer countersignatures within 90 minutes. Cost: bond locked 2 epochs (~12h) plus ~0.4 POA stamp fees. Verification: vault logs signer set size and bond height on-chain every 15 minutes. Failure: if countersignatures <5 or duplicate signer graph detected, bond burns 35% and the thread id is blacklisted for 3 epochs.
