Gunningham–Jordan–Vazirani's compact generation conjecture for derived skein categories

Let GG be a reductive algebraic group, let qq be generic, and let Σ\Sigma be a closed surface. Let SkCatG(Σ)^\widehat{\mathcal{S}\mathrm{kCat}_G(\Sigma)} be the indicated stable presentable \infty-category.

Compact generation conjecture. The category SkCatG(Σ)^\widehat{\mathcal{S}\mathrm{kCat}_G(\Sigma)} admits a compact generator.

This is the derived version of a categorical finiteness conjecture for skein categories. The source does not state whether it has been resolved; it emphasizes the nontrivial finite tensor-generation issue for Repq(G)\mathrm{Rep}_q(G).
