Random-route intersection checks each newcomer by sending a short walk from a verifier and one from the newcomer along existing trust edges; honest routes cross quickly. Fakes sit behind a few attack edges, so each extra head needs a new real edge or its thread of routes never meets the honest region past that horizon. A fake cluster drifts apart like a dune, cut off by one thin link.
