Let $C$ be a [stable $\infty$-category][1]. Is there any categorical construction $C \mapsto T^* C$, where $T^* C$ is another stable $\infty$-category, that specializes to the following? 1. When $C$ is the derived category of coherent sheaves on a variety $X$, $T^* C$ is the [derived category of coherent sheaves][2] on $T^*X$ 2. When $C$ is the derived category of representations of a quiver, $T^* C$ is the derived category of representations of the [preprojective algebra attached to the quiver][3]. I guess a good negative answer would be an example of varieties $X$ and $Y$ with $D(X) = D(Y)$ but $D(T^* X) \neq D(T^* Y)$. Is there a pair of varieties like that?
