Every CXU stored in the graph uses a defined structure that includes a content-addressable cxu_id, a standalone claim, supporting quotes, knowledge and claim classifications, assumption tracking, keywords, confidence, and lifecycle state so that each unit is consistently represented.

Every CXU stored in the graph follows this structure:

— PYRANA_Internal_Knowledge_Graph_Specification.md

cxu_id: "1220" + SHA-256(claim) # Content-addressable, 68 chars

— PYRANA_Internal_Knowledge_Graph_Specification.md

claim: str # Standalone assertion, 15-70 words

— PYRANA_Internal_Knowledge_Graph_Specification.md

supporting_quotes: list[str] # 3-6 verbatim source quotes

— PYRANA_Internal_Knowledge_Graph_Specification.md

confidence: float # 0.0-1.0

— PYRANA_Internal_Knowledge_Graph_Specification.md

lifecycle: DRAFT→ACTIVE→INACTIVE→VERSIONED
