Every CXU stored in the graph must include an is_assumption boolean that is set to true for projections and estimates so that assumption-bearing knowledge is explicitly marked.

Every CXU stored in the graph follows this structure:

is_assumption: bool # True for projections, estimates

— PYRANA_Internal_Knowledge_Graph_Specification.md
