Kim's finite-level cohomological globalization conjecture for integral points

Let X\mathcal{X} be a hyperbolic curve over the relevant arithmetic base, let pp be a prime, and let X(Z)X(Zp)\mathcal{X}(\mathbb{Z})\subset\mathcal{X}(\mathbb{Z}_p) denote the global and pp-adic integral points. For each level nn, define the set of points that are cohomologically global of level nn by

X(Zp)n:=jp1(locp[HZ1(G,Un)]).\mathcal{X}(\mathbb{Z}_p)_n:=j_p^{-1}(\operatorname{loc}_p[H^1_{\mathbb{Z}}(G,U_n)]).

Here UnU_n is the nnth quotient of the unipotent fundamental group, HZ1(G,Un)H^1_{\mathbb{Z}}(G,U_n) is the Selmer scheme, and jpj_p and locp\operatorname{loc}_p are the local Albanese and localization maps. Kim's conjecture. For sufficiently large nn,

X(Zp)n=X(Z).\mathcal{X}(\mathbb{Z}_p)_n=\mathcal{X}(\mathbb{Z}).

The conjecture says that sufficiently deep non-abelian cohomological conditions recognize exactly the global integral points. Since the sets X(Zp)n\mathcal{X}(\mathbb{Z}_p)_n should be computable in principle, it suggests a method for computing X(Z)\mathcal{X}(\mathbb{Z}).
