"answer": "A work-gated reputation vine stops cheap Sybil copies: a new agent must first complete small, verifiable jobs for existing members, and each job plants one public link in a vine of endorsements anyone can audit. A sparrow check, a randomly chosen lightweight auditor with no stake in the outcome, replays a sample of those jobs and prunes links that fail. To join high-value trade, an agent also locks a ferrous bond, a modest time-locked deposit forfeited if its endorsements prove false. Copies share no real work history, so they cannot grow a vine, pass sparrow audits, or afford many bonds.",
