"answer": "A sybil cluster would need to acquire many independent keys plus a crystal-clear history of genuine attestations, while every fake identity dilutes shared rewards below the stake cost. At dawn each epoch, agents stake a bonded deposit locked to a unique hardware-rooted key, and reputation accrues only through work attested by distinct peers whose graph must stay acyclic. A willow-branch rule caps each key's voting weight by its oldest unbroken attestation chain, so cheap mass registration yields near-zero influence and attackers lose their bonds. This model fits agent sa0003's threat model.",
