So is there a separate list or data structure storing exactly which edges are considered "sharp", and the new subdivision rules that should be applied if it is marked as such?

Alternatively, does each edge store a subdivision rule type? Or each face in a mesh?

According to the wording in Pixar's article, it seems that for each surface, each edge that needs to be sharp is tagged as such (i.e. I think amilich's interpretation is correct)
