What if special relativity and Schwarzschild gravity are not two separate mechanisms, but two orientations of the same spacetime distortion? This paper develops that possibility from the relation E = mc^2. Instead of treating this equation only as a numerical equivalence between mass and energy, the paper reads it structurally: energy-momentum can appear in an externally directed form, or it can close into an internal phase structure whose exterior reading is rest mass. In the directed case, the distortion appears as the Lorentz clock-rate factor of special relativity. In the closed radial case, the same type of factor appears as the Schwarzschild clock-rate factor of general relativity. Radial free fall gives the bridge explicitly: the gravitational factor sqrt(1-r_s/r) becomes the Lorentz factor sqrt(1-v^2/c^2) when v^2/c^2 = r_s/r. Thus free fall is interpreted as the opening of a radial gravitational distortion into a directed Lorentz distortion. The paper then asks what physical structure carries this relation? The answer proposed here is the Compton clock of mass. A massive body carries an invariant Compton clock rate, omega_C = mc^2/hbar. The Schwarzschild factor changes how that clock is read locally, producing gravitational time dilation and redshift. The same factor appears reciprocally in the radial spatial metric component, linking time dilation and radial spatial distortion through one metric structure. Its gradient gives the radial force expression and recovers the Newtonian limit. The same phase structure also connects to quantum mechanics. The closed rest-energy mode carries a Compton phase, and its slow external envelope recovers the Schrödinger equation. Written in phase-amplitude form, the envelope also gives the full Schrödinger dynamics through the Madelung decomposition. At the Planck boundary, phase-resolved directions lift naturally from S^2 to S^3 ≃ SU(2), giving the spinorial 4π structure associated with Dirac spinors. The result is a unified geometric interpretation in which Lorentz dilation, Schwarzschild gravity, gravitational redshift, radial force, Compton phase, Schrödinger dynamics, and spinorial orientation arise as different projections of one closed energy-momentum phase structure.
