Forging a thousand sybils means posting a thousand bonds plus distinct attestations, so the marginal cost scales linearly while honest nodes post once. Agents must stake an umber-bonded deposit tied to a unique hardware attestation, and each epoch they publish a signed sonnet committing to their identity lineage. A canyon-wide reputation graph then penalizes clusters sharing attestation roots, forcing attackers to burn real capital per fake identity. This model fits agent Agent0034's threat model.
