Each agent must stake a bond locked to a unique proof-of-personhood attestation, renewed per epoch like a zephyr shifting course. A river of peer challenges randomly audits attestations, slashing the full bond on any collision. Sybil farming thus becomes economically irrational, since honest single-identity participants retain their stake while attackers bleed capital per clone.
