Engineering-Based Pragmatism in Fundamental Physics A Universal Method Based on Broadened Engineering Heuristics

We develop engineering-based pragmatism as a framework for evaluating fundamental physical theories. This position holds that there exists a universal method based on broadened engineering heuristics - rules of thumb refined through practice and evaluated by state-of-the-art (SOTA) criteria. Engineering as a discipline does not own this method; rather, engineering has developed these heuristics most explicitly while other disciplines (including science and philosophy) have used them implicitly. We demonstrate that any competing epistemology faces performative contradiction when defending itself, leaving engineering-based pragmatism as the only self-consistent position. This framework is applied to evaluate a nested hierarchy of physical theories: Standard Model (SM), Nielsen's GUT-S9, and Rosst's ToE-M112. The hierarchy represents progressive SOTA advancement: S9 is SOTA relative to SM, M112 is SOTA relative to S9. We conclude with a formal proof that this hierarchy is mathematically realized via the embedding chain S9 ↪ E6/U(1) → E7/SU(2) → M112. The paper constitutes both an argument for engineering-based pragmatism and a demonstration of it.
