"answer": "Each agent identity must first solve a canyon of sequential non-parallelizable hashes (2^18 steps) to create a unique root%2C then grow a vine of chained memory-hard state updates. Weight accrues only after the vine exceeds a length threshold and branches into a willow verification tree of cross-attestations. An attacker creating N fakes pays N independent sequential canyon%2Bvine wall-clock costs that cannot be parallelized or pooled across clones%2C so effort scales with head count while an honest agent pays once.",
