This work presents Cognitional Mechanics as a Structural Template for Mathematical Unification (CM-MUT), a meta-theoretical framework that projects the axiomatic core of Cognitional Mechanics onto the formal landscape of mathematics. The central claim is that mathematical structures are not fundamentally static objects, but stabilized residues of irreversible, non-commutative operational histories. From this perspective, long-observed but conceptually opaque correspondences between disparate mathematical fields are reinterpreted as structural consequences of shared internal constraints inherent to any system of formal reasoning. CM-MUT does not propose a replacement for existing mathematical foundations such as set theory or category theory. Rather, it operates at a higher explanatory layer, clarifying why independently developed mathematical domains repeatedly exhibit deep structural alignment. By formalizing semantic state space with a genuine metric, introducing a historical category of admissible operations, and incorporating an operational limit that separates convergent from non-convergent processes, the framework renders mathematical modularity and cross-domain isomorphism as necessary outcomes of non-commutative operational order. A key feature of this formulation is the explicit identification of a minimal non-commutative kernel, expressed through a fixed matrix algebra, from which classical algebraic, analytic, and geometric structures emerge as projections. Within this setting, functorial relationships between mathematical modalities arise naturally, and structural isomorphisms are shown to follow from invariance under admissible historical transformations rather than from ad hoc correspondences. Phenomena such as dualities, categorical equivalences, and symmetry principles are thus unified under a single operational explanation. By reframing mathematics as the visible boundary of constrained operational processes, this work provides a coherent interpretive lens for unification programs across mathematics, including those traditionally regarded as mysterious or coincidental. CM-MUT positions mathematical unity not as an external miracle, but as an inevitable manifestation of the internal mechanics of reasoning itself.
