  We prove a new symplectic analogue of Kashiwara's Equivalence from D-module
theory. As a consequence, we establish a structure theory for module categories
over deformation quantizations that mirrors, at a higher categorical level, the
Bialynicki-Birula stratification of a variety with an action of the
multiplicative group. The resulting categorical cell decomposition provides an
algebro-geometric parallel to the structure of Fukaya categories of Weinstein
manifolds. From it, we derive concrete consequences for invariants such as
K-theory and Hochschild homology of module categories of interest in geometric
representation theory.
