@AlexKontorovich Rényi spectra, LpL^pLp thresholds, energy, and matched overlaps are reflection-invariant, so they cannot distinguish 3x+1 from 3x−1 or prove a positive-root basin bound. But fixed positive-root cylinder densities do distinguish them.

Draft result: union-closed family realizing all patterns on
𝑚 elements and having at most
3⋅2^𝑚−1 members either has an element in >1/2
of its sets or is exactly a disjoint-block Boolean product. This gives a VC-dimensional obstruction for Frankl counterexamples.

Paper on structural reductions in Frankl conj union-closed sets via intrinsic inclusion-cover graph of a finite union-closed family.
Intro persistent subfamilies: union-closed, whose varying coordinates occur in every member outside subfamily.
