The Pro-\'Etale Topos as a Category of Pyknotic Presheaves

Let $X$ be a coherent scheme and let $\mathrm{Gal}(X)$ denote the Galois category of $X$, as introduced by Barwick, Glasman and Haine. In this paper we prove that the hypercomplete pro-'etale $\mathrm{\infty }$-topos $X_{\mathrm{proet}}$ of $X$, introduced by Bhatt and Scholze, is equivalent to the category of continuous representations of $\mathrm{Gal}(X)$ with values in the $\mathrm{\infty }$-category of pyknotic spaces.
