ENAppendix HIS v2.0. A concise historical and conceptual timeline that links DD-U (Dualbind Universe) ontology to physics-facing descriptions, paired with The Dualbind Gravity Model (Paper A v2.0) and The IXUS Protocol 3.2 (Paper B v2.0). It contextualizes the emergence of Koma-based effective geometry and the protocol-driven mapping across layers, and can be read alongside Paper X for integration.
