| contents | An orientation theory for flow categories without bubbling is determined by a functor of $\infty$-categories $μ\colon \mathcal{C} \to U/O$. For any such functor, we construct a stable $\infty$-category $\mathcal{F}low^μ$ of $μ$-structured flow categories and bimodules. We also construct the expected functors between such $\infty$-categories, giving a tractable framework for manipulating orientations, local systems, and filtrations in exact Floer homotopy theory. Classifying spaces for certain bordism theories determined by $μ$ appear as mapping spaces in $\mathcal{F}low^μ$, and we use a Pontrjagin--Thom construction to naturally identify $\mathcal{F}low^μ$ with the $\infty$-category of $μ$-twisted presheaves on $\mathcal{C}$. |
