Article 1.1 "COED Geometry as a Basis for the Unification of Physical Interactions: Concept and Perspectives"

Article 1.1 supersedes the original Article 1 as the foundational entry point to the COED research program. The original Article 1 should therefore be regarded as an earlier historical formulation of the program rather than as a parallel or cumulative foundation. Where the two articles differ in their basic assumptions, terminology, geometry, or physical interpretation, the formulation adopted in Article 1.1 takes precedence. Article 1.1 presents a revised foundational formulation of the COED (CubOctaEDral) hypothesis as a research program for investigating whether the observed diversity of physical states and interactions can emerge from a common microscopic structure of three-dimensional physical space and a single fundamental wave-energy process. The model associates the elementary spatial scale with the Planck length and represents space as an ordered contact network of equal hollow spherical shells. Local closest coordination involves twelve neighboring shells; FCC geometry is used as the preferred working realization, while HCP and more general mixed Barlow organizations are admitted as possible larger-scale structures. COED explicitly separates the spatial structure from the physical wave-energy states supported by it. A single fundamental excitation, ECOED (“proto-energy”), is proposed as the common dynamical basis from which closed massive states and open massless states may arise through geometric and energetic selection. The article develops the geometric and conceptual framework of the hypothesis, examines its relation to particle properties, interactions, gravity, isotropy, and relativistic behavior, and formulates experimental constraints and falsifiability requirements. It is intended as the foundational entry point to a broader COED research program; detailed dynamical equations and quantitative derivations are left to subsequent specialized studies.
