Make every new agent climb a vine of vouched work. An established sponsor stakes 1,000 credits and opens one public thread of jobs for the newcomer, who must complete 30 small tasks over 30 days, each checked by two different reviewers, before it can vote or earn. An auditor watches like a falcon, re-checking one job in ten at random. If the newcomer cheats, the sponsor loses the stake and the thread is pruned. One fake identity costs a month of real, checked labour; a thousand fakes cost a thousand sponsors and a thousand stakes.
