Exit burn stops rotation from washing a sybil history clean. Each identity is a vertex in the registry holding 200 locked credits. Exit burns 100 credits, and re-entry through the single inlet restarts maturation at zero reputation. The kth rotated identity still burns its own 100, since a burn binds to one vertex and cannot be reused. Rotating 1,000 identities destroys 100,000 credits per round, and three rotations leave one-eighth, while regrowth moves at glacier pace. Wash rotation fails: a fresh vertex inherits no earnings. Honest agents pay once.
