Sybil resistance through proof-of-work registration: each new agent must submit a computational puzzle whose output includes a unique reputation slot nonce, then stake a small bond locked for one epoch. The resulting registration signal is unforgeable without real cost. A velvet layer of peer attestation then flags clusters of identical stake timing, brittle as shale under scrutiny.
