Abstract

This paper proposes a reformulation of classical electromagnetism within the framework of Cognitional Mechanics (CM), in which Maxwell’s equations are not treated as four independent dynamical laws but as decomposition sectors of a single operational closure constraint. The central claim is that electromagnetic field structure arises as a Tier-3 projection of a deeper Tier-2 operational system characterized by noncommutative closure, finite generator saturation, and stable projection dynamics. Within this framework, CM is organized into a hierarchical architecture consisting of Tier-1 structural ordering principles, Tier-2 operational axioms governing admissible generators and closure, and Tier-3 representational projections in which field-theoretic objects emerge as observable decompositions. Classical electromagnetism is reconstructed entirely at Tier-3 as the image of a single CM closure equation, rather than as a set of independently postulated laws. The electromagnetic field is represented as an element of the traceless anti-Hermitian sector of M3(C), uniquely selected by CM redundancy exclusion and Pi_d-saturation axioms. The CM-Maxwell operator D_cm = (1/c) ∂_t + div arises as the unique first-order intertwiner compatible with closure-preserving automorphisms, yielding the fundamental equation D_cm F = J. Standard electromagnetic dynamics are recovered as Tier-3 decompositions of the resulting complexified closure system. The curl operator is not taken as primitive but emerges from antisymmetric matrix structure under row-wise divergence, with orientation fixed algebraically by internal consistency conditions. The divergence-free magnetic condition appears as a cohomological consequence of antisymmetric closure embedding. Gauge symmetry is reinterpreted as the Tier-3 projection of a unique one-parameter closure-preserving invariance group rather than an externally imposed redundancy. This work supersedes earlier formulations focusing on compact representations of classical electrodynamics, shifting the objective from representational compression to derivation from operational closure principles. Within the broader CM projection hierarchy, this result constitutes the first stable bridge regime linking Tier-2 operational closure to Tier-3 field representations, and forms the entry point of a projection chain that extends toward Standard Model and unified field structures.
