(2.2) Kontsevich and Soibelman postulated that $\mathrm{Sk}(X)$ should be the base of the non-archimedean SYZ fibration, but the definition of $\mathrm{Sk}(X)$ does not provide us with a map $X^{\mathrm{an}}\to\mathrm{Sk}(X)$. To construct such a map, we will use an alternative description of the essential skeleton that appeared in [NX16a]. Let $\mathscr{X}$ be a minimal dlt-model of $X$, and denote by $\mathscr{X}^{\mathrm{snc}}$ the open subscheme of $\mathscr{X}$ consisting of the points where $\mathscr{X}$ is regular and $\mathscr{X}_{k}$ has strict normal crossings. Then the dual intersection complex $\Delta(\mathscr{X}^{\mathrm{snc}})$ of $\mathscr{X}^{\mathrm{snc}}_{k}$ can be canonically embedded into $X^{\mathrm{an}}$ (see [MN15, §3]). It follows from [NX16a, 3.3.3] that the image of this embedding is exactly the essential skeleton $\mathrm{Sk}(X)$. To be precise, it is assumed in the statement of [NX16a, 3.3.3] that $\mathscr{X}$ is $\mathbb{Q}$-factorial and defined over an algebraic curve, but these assumptions are not used in the proof. If the minimal dlt-model $\mathscr{X}$ is good, we will now construct a continuous retraction $\rho_{\mathscr{X}}\colon X^{\mathrm{an}}\to\mathrm{Sk}(X)$ by generalizing the construction for snc-models in [MN15, 3.1.5].
