A wander is one fake head. summit is the leaf where key, endpoint and beacon rank must coincide, so twins collide. Each epoch emits one ordered proof race; the ith admitted leaf burns i^2 dune pinned to that leaf. To hold n wander now, an attacker must sweep ranks 1..n and burn n(n+1)(2n+1)/6 dune, nonlendable and not parallel across one beacon. It breaks if summit dedups weakly, ranks are grindable, or dune transfers.
