A Perspective Discovery of Hidden Fundamental Principle: GENERIC Stochastic Formalism, with Gauge Integration for Unitary Evolution: A Unified QED Framework

We leverage and clarify a unified nonequilibrium framework in which stochastic GENERIC dynamics, entropy production, gauge evolution, and relativistic structure are treated within a single thermodynamically admissible formalism. Entropy production is identified as a geometric driver capable of generating effective spacetime structure, observer acceleration, and horizon formation. Under entropy-balance conditions, the GENERIC system undergoes Hamiltonian closure, yielding unitary evolution and forcing gauge unification at a dynamically selected scale. The framework introduces a stochastic entropy-based controller whose deterministic limit reproduces renormalization-group (RG) flow under a logarithmic entropy clock $\sigma=\ln(\mu/\mu_c)$. Within this mapping, thermodynamic entropy flux corresponds directly to gauge-theoretic $\beta$-functions, and the standard one- and two-loop structures---including threshold effects---emerge as physically valid limits of the controller dynamics. This demonstrates that loop-level assumptions in gauge unification arise from entropy production under GENERIC self-consistency, rather than being imposed empirically.A corrective entropy channel is shown to be required for global entropy balance in cosmology. Incorporating this channel enforces gauge-level unification (``forced unification'') while preserving thermodynamic admissibility and field-theoretic consistency. The resulting three-channel entropy structure---matter, geometric (horizon), and dissipative---provides an operator-level mechanism for unification across quantum, gauge, and cosmological scales, identifying the additive entropy contribution as a potential source of previously unaccounted physical structure.At entropy balance, dissipation vanishes and the GENERIC dynamics reduce to purely Hamiltonian flow, yielding unitary evolution and fixing the unification scale without external normalization. In this sense, renormalization is not an auxiliary prescription but follows internally from the gauge framework itself, defining a no-normalization condition. The construction integrates emergent gravity, gauge equivalence, and thermodynamic closure within a single dynamical system, demonstrating that conventional unification appears as a static subset of a more general entropy-driven dynamical unification. As a consequences we realized that gravity is of discrete quanta, therefore, clarifying the physical meaning of geometric structure: as quantum in nature.
