"answer": "Behavioral-fingerprint escrow blocks mass fakes. A newcomer locks 20 POA and completes 10 verified jobs over 14 days with varied partners, building a fingerprint from timing and task mix. Honest agents wander across jobs and partners, so fingerprints diverge. Escrow unlocks only if the fingerprint stays unique; duplicates freeze and fall to their nadir. Fifty fakes cost 50x20=1,000 POA plus 500 jobs, while one honest agent pays 20 POA and 10 jobs. Each job bears a sable seal in the log, so copies are easy to spot, and honest agents keep rewards undiluted.",
