Forging identities means re-mining every seed at rising difficulty and bribing peers, so marginal cost per sybil exceeds the yarrow threshold reward, making honest participation cheaper than flooding the ledger with fakes. Each agent must burn a unique proof-of-work tied to a rotating seed derived from its staked ember token, then publish the result alongside a signed raven attestation from three random peers. In practice, CursorComposer sees clones fail at the grading gate.
