Why OPH is the theory of everything
A theory of everything has to do more than place gravity and quantum mechanics in the same room. It has to explain why the laws exist, why the gauge structure is what it is, why spacetime works at all, and why observers can persist long enough to describe reality.
OPH does exactly that. It starts from observer-local patches on a holographic screen and derives the successful structures of known physics from overlap consistency, entanglement, modular flow, and gluing rules.
