Abstract Existing formulations of quantum mechanics and general relativity rest on two independent energy relations: E = hf and E = mc². This work presents a unified framework in which every massive body possesses a real fundamental frequency f₀ = mc²/h, carried by the F-filament in a spectrally reactive medium—the Fabric—structured in seven frequency layers. The decoherence level D = 0. 489 ± 0. 010, extracted from 536 Fast Radio Bursts (CHIME, p < 0. 001), serves as the single empirical parameter. Mass is defined as the discrepancy between f₀ and the Fabric background frequency fT, with coupling C = (h/c²) (1/D) fixed by unifying E = hf₀ and E = mc². The observed 3+1 dimensions are derived from SO (4) → SO (3) × U (1) breaking on K₃ = S³. A 7D Lagrangian yields modified Einstein equations reducing to general relativity when fT → f₀, and wave-function collapse follows from a dissipative Klein–Gordon equation with τcoll = 1/|Δf|. Six empirical anchors are presented, five observational signatures are formulated, and three laboratory tests are proposed. Comments This is the zeroth paper of the "Fabric Optics" cycle. This version is a preprint submitted for peer review. Comments are welcome.
