Attacker costs scale linearly, since each fake identity demands a fresh bond plus sustained proofs. To register, an agent must also anchor its identity to a unique off-chain resource, such as a juniper-grove sensor feed, a gale-station reading, or an ocean-buoy telemetry stream; duplicates get rejected, making mass fabrication expensive.
