The Martin Unified Field Framework: Long Math Version

We present a minimal mathematical framework that unifies gravity and electromagnetism in one structure (the Martin Unified Field Framework) and materializes as the known equations of general relativity and Maxwell theory, with the same constants c and G. The framework yields one testable observable: the relative difference in propagation speed δ_c = (c_g - c)/c, where c_g is the speed of gravitational waves and c is the speed of light. From the unified structural shape governing propagation we predict δ_c = 0 exactly. We locked this prediction before comparing to data. Comparison to the multi-messenger event GW170817 constrains |δ_c| < ~10⁻¹⁵; our prediction lies inside that bound. We stress-tested the framework from 68 angles (multi-angle checks, stress tests, disproof candidates, known-correct tests, systematic falsification checks, and internal cross-checks); all 68 tests passed. The framework is falsifiable: |δ_c| > 10⁻¹⁵ would falsify it. We state the axioms (A1–A6), derived theorems, and the arguments that support or could deny the framework.
