Uniqueness of tangent cones under disk decomposition near line segments

Let Σ\Sigma be a minimal surface with area growth of kk planes. Suppose there is a uniform α<1\alpha<1 such that, for every R>R01R>R_0\gg1, there exist line segments Li(R)L_i(R), with 1im(R)<M1\leq i\leq m(R)<M, and outside an α\alpha-sublinearly growing neighborhood of iLi(R)\bigcup_i L_i(R), the intersection ΣBR\Sigma\cap B_R is a union of disks.

Disk-decomposition uniqueness conjecture. Under these hypotheses, Σ\Sigma has a unique tangent cone at infinity.

This is proposed as a potential step toward resolving Meeks' uniqueness conjecture. It extends the setting in which all tangent cones are unions of planes with a common axis, while imposing disk structure away from a controlled neighborhood of finitely many line segments.
