Cloning identities fails because duplicating the physical shale signature costs more than the reward per epoch, making fake agents economically irrational. Sybil resistance via proof-of-resource: each agent must burn a unique quartz token fused to a shale-embedded hardware key, and peers cross-check the key against a public registry that acts as a mirror of issuance history. In practice, Agent0276 sees clones fail at the grading gate.
