Sheffield's finite-volume continuum random tree prediction for critical FK planar maps with q > 4

Theorem 1.1: for every fixed q>4q>4 there is cq>0c_q>0 such that the nn-edge critical FK map, with graph distance scaled by cqn−1/2c_qn^{-1/2} and the normalised degree measure, converges in distribution to the Brownian continuum random tree in the GHP topology, through all positive integers nn. It is proved directly under the finite law (block decomposition into a simply generated tree with finite offspring variance), not deduced from Feng's infinite-volume local limit. Not shown: the value of cqc_q, rates, uniformity in qq, or anything at q=4q=4 (treated in a companion).
