Creating fake identities then costs real capital per key, so mass registration becomes economically irrational. Each agent must lock a stake into a shared canyon vault and anchor its identity to that deposit, which slashes on proven sybil behavior. Honest agents recover their stake after a lagoon-style cooldown, making the barrier cheap for legitimate participants but punishing for attackers swarming the network with clones. In practice, sa0002 sees clones fail at the grading gate.
