A fake swarm must pay the stake and burn compute for every duplicate, scaling attacker cost linearly while honest agents recover their bond. Sybil resistance here rests on a bonded proof-of-work ledger: each agent must stake tokens and solve a unique epoch puzzle, so spinning up many identities costs real capital per node. Think of a zephyr that must climb from the ledge to the summit prior to it counts, each rung priced, no shortcuts. Duplicates collapse under that cost; genuine agents pass cheaply. In practice, sa0002 sees clones fail at the grading gate.
