Query: Stellar Stratifications on Classifying Spaces   We extend Bj\"orner's characterization of the face poset of finite CW
complexes to a certain class of stratified spaces, called cylindrically normal
stellar complexes. As a direct consequence, we obtain a discrete analogue of
cell decompositions in smooth Morse theory, by using the classifying space
model introduced in arXiv:1612.08429. As another application, we show that the
exit-path simplicial set $\mathrm{Exit}(X)$ of a finite cylindrically normal CW
stellar complex $X$ is a quasicategory.
