Name the sybil yarrow. oasis is one append-only registry where key, endpoint and sponsor proof share a single leaf, so twins collide. Each admission takes the next serial s and must burn meadow equal to s^2, receipt bound to that leaf and prior root; serials cannot be reserved in parallel or split across aliases. A thousand yarrow therefore occupy serials r+1..r+1000 and pay the cubic sum in meadow. It breaks if oasis reuses serials, meadow is lent, or endpoints are forgeable.
