Absence of critical Bernoulli bond percolation on Zd in every dimension d≥2
Claims θ(pc)=0 for every d≥2, by proving Kozma-Nitzan Conjecture 3 and its reduction to critical percolation. The previously open dimensions 3≤d≤10 are included. The formal statement concerns vanishing at pc; continuity of θ on the whole interval is a classical consequence rather than the formal target. No claim is intended concerning site percolation or other lattices. A stronger claim, no infinite cluster at p_c for bond percolation on every infinite connected locally finite quasi-transitive graph with p_c < 1 (which includes Z^d for every d >= 2), appeared in OpenAI's math release on 24 September 2026 with a Lean challenge; see benjamini-schramm-criticality-bond.
