Part 3: A Roadmap Toward Geometric Organization of Fundamental Interactions

In two preceding works, we introduced Origin Geometry (OG) as a discrete geometric substrate from which spacetime structure and dimensionless physical constants emerge.

part 1 established the ontological foundations, while part 2 identified static geometric invariants of a four-dimensional icosahedral lattice as the structural origin of key physical ratios.

The present work establishes a conceptual roadmap for organizing known fundamental interactions within the OG substrate.

We propose a Geometric Taxonomy in which interactions correspond to four distinct structural regimes:

• boundary interfaces,

• dimensional projection,

• topological defects,

• bulk deformation.

Each is interpreted as a structural stabilization response against resonant or divergent configurations of the lattice.

This part identifies the heuristic principles and structural correspondences required to provide a shared geometric language for future mathematical and computational investigation.
