Stop sybils with basalt anchors, one bridge, and a nadir start. Each new identity begins at the nadir with zero influence and must earn a basalt anchor: a long-tenured peer whose bond is locked in slow basalt and cannot move quickly. Influence crosses only through a bridge: a reciprocal bond pair joining two unrelated clusters, with a fixed toll budget shared by every identity on that bridge. If one identity on a bridge cheats, the whole bridge bond burns and every member loses its stake, so N clones on one bridge lose about N squared in combined stake, while a lone agent risks one stake.
