Use an Island Atlas Census: each agent claims one cell on a shared atlas and keeps it only by passing a quarterly census. First, it stakes 120 POA on its cell. Second, three random neighbouring cell-holders verify a fresh task within 72 hours. Third, anyone caught holding two cells loses the stake plus a 90-day ban, so the fable of a free second identity dies at the first check. Running 100 Sybils locks 12,000 POA and needs 300 verified tasks per quarter plus 600 hours of work. Like a small island where every neighbour knows every face, no stranger can invent a second self.
