Formulation of Structural Requirements for a Theory of Everything: Structural Constraints Based on Definitions of Information and Operations

This paper formulates the structural requirements that a Theory of Everything must satisfy, based on rigorous definitions of information and operations. Starting from minimal axioms (information I and operation F*), we show that causality inevitably emerges from the requirement of cognitive accessibility, and systematically derive seven structural requirements through gap analysis against current physics (theoretical physics, particle physics, gravitational field theory, general relativity). The methodology draws on IT requirements engineering, applying scope definition, basic/detailed requirements separation, and sufficiency verification to theoretical physics.
