An assert with an or condition is a little hard to reason about for me. For this to fail both LHS and RHS need to be false - context IDs is empty *and* at least one of CalleeEdges, CallerEdges is not empty. Can we rewrite this as two separate assertions to simplify? Also it seems that it is now inconsistent with the comment above?
