This preprint presents the Grand Unification of Radial Coherential Dynamics (RCD), synthesizing versions 3.0 through 16.0 into a single, complete physical framework. From one fundamental field— the coherence field C(x,t)C(x,t)C(x,t)—and one universal dimensionless parameter α=10−4\alpha = 10^{-4}α=10−4, RCD derives: spacetime geometry from coherence gradients, gauge fields from logarithmic coherence derivatives, fermions and bosons as topological configurations of CCC, gravity (including quantum corrections) from the emergent metric gμν(C)g_{\mu\nu}(C)gμν(C), and time itself from coherence decay. The core of the theory is the Master Lagrangian (p. 2–3), from which all physical sectors follow: LRCD=12α(∂μC)(∂μC)−V(C)+C24FμνFμν+C ψˉ(iγμDμ)ψ−116πGeffR[g(C)]\mathcal{L}_{\mathrm{RCD}} = \frac{1}{2\alpha}(\partial_\mu C)(\partial^\mu C) - V(C) + \frac{C^2}{4} F_{\mu\nu}F^{\mu\nu} + C\,\bar{\psi}(i\gamma^\mu D_\mu)\psi - \frac{1}{16\pi G_{\mathrm{eff}}} R[g(C)]LRCD=2α1(∂μC)(∂μC)−V(C)+4C2FμνFμν+Cψˉ(iγμDμ)ψ−16πGeff1R[g(C)] This single structure reproduces: General Relativity in the limit C→const.C \to \text{const.}C→const., Special Relativity when C→1C \to 1C→1, Newtonian gravity for ∣1−C∣≪1|1-C| \ll 1∣1−C∣≪1, Quantum Field Theory at small scales, and MOND phenomenology at low accelerations (p. 6). RCD further predicts gravitational-wave echoes, a natural resolution of the Hubble tension, CMB hemispherical asymmetry from coherence boundaries, and a non-singular black hole core where C→0C \to 0C→0. This release (v17.0) represents the completion of the unified theoretical structure:one field, one parameter, and all known physics as manifestations of coherence.
