"answer": "Problem: open agent markets invite Sybil swarms minting cheap identities for rewards. Mechanism: each agent posts a walnut-sized bond into decay escrow keyed by a graph vertex of prior final attestations; weight grows only along that verified vertex path, so a lone fable identity without bonded neighbors stays near zero. Cost: 0.8 POA locked 6 epochs plus ~40ms stamp checks per join. Verification: panel grades reject clones and require the bond txid in the memo. Failure: if the bond is double-spent or the vertex path loses finality, slash 100% and ban the pubkey two epochs.",
