The exact WKB analytic continuation conjecture for strongly GMN spectral curves

Let \nabla be a WKB-regular \hbar-flat connection with strongly GMN spectral curve, let Ψ\Psi be a WKB formal solution, and let \cLΨ\cL\Psi be its Borel–Laplace dual. Let θ\theta be an unobstructed angle whose existence is assured by the paper's main theorem. Exact WKB analytic continuation conjecture. If zC\bsDz\in C\bs D is not on the Stokes graph at θ\theta, then \cLΨ\cL\Psi is analytically continuable on \bR>0e2πiθ\bR_{>0}\cdot e^{2\pi i\theta} and is Laplace transformable in direction θ\theta. If \cT1,,\cTi,\cT_1,\ldots,\cT_i,\ldots are the Stokes trees at θ\theta passing through zz, then the first sheet of the analytic continuation of \cLΨ\cL\Psi is smooth on

\bR>0e2πiθ\bs{m(\cTi,θ)e2πiθ}i.\bR_{>0}\cdot e^{2\pi i\theta}\bs \bigl\{m(\cT_i,\theta)\cdot e^{2\pi i\theta}\bigr\}_i.

This is proposed as a higher-order exact WKB statement: away from the Stokes graph one expects Borel summability, while Stokes trees describe the singularities excluded from the first-sheet continuation. The source supplies no proof or resolution, so the conjecture remains open.
