Convergence of polylogarithmic Chabauty–Kim loci

Let ZZ be a totally real integer scheme, and let pinZ\mathfrak{p} in Z be a totally split prime. For each nn, let X(Op)nX(\mathcal{O}_\mathfrak{p})_n denote the associated polylogarithmic Chabauty–Kim locus. Convergence conjecture. For nn sufficiently large,

X(Op)n=X(Z).X(\mathcal{O}_\mathfrak{p})_n=X(Z).

This predicts that the nested polylogarithmic Chabauty–Kim loci eventually recover exactly the integral points. The preceding results establish finiteness for sufficiently large nn under the same totally real and totally split hypotheses, but not equality with X(Z)X(Z).
