Gravity and Temporal Coherence in the Zero‑Point Event‑Based Time‑Spectrum (ZEBTS) Paradigm: A Closed Axiomatic Proof System

<jats:p>The χ‑spectral framework developed in this work establishes a unified operator‑geometric foundation for physical law, integrating quantum measurement, modular state reduction, spectral geometry, and gravitational curvature into a single mathematically coherent structure. Physical measurement is formulated as an intrinsic operator‑spectral transition generated by the bounded self‑adjoint observable M_chi(k) = Phi_chi(k) + B_chi(k) + R_chi(k), which combines phase geometry, boundary tension, and χ‑spectral curvature into a non‑singular measurement mechanism. Probability amplitudes P_n(k) = |_chi|^2 are derived directly from the χ‑inner product, demonstrating that Born’s rule emerges from arithmetic geometry rather than axiomatic postulates. A central result of the χ‑spectral framework is the rigorous proof of compatibility between ZEBTS‑SUPER gravitational dynamics and quantum mechanics. Gravitational curvature R_chi(k) enters the measurement operator M_chi(k) as a bounded geometric observable, ensuring ultraviolet stability, finite expectation values, and strict unitarity across all scale layers. Collapse dynamics are formulated as bounded modular projections, guaranteeing non‑perturbative, divergence‑free state reduction. Decoherence is shown to be a structural spectral gradient D_chi(k) = M_chi(k+1) – M_chi(k), providing a deterministic geometric mechanism for coherence loss without environmental reservoirs. The scale‑layer commutator C_chi(k) = [M_chi(k+1), M_chi(k)] encodes contextuality and order‑dependence as structural consequences of χ‑operator geometry. Together, these results demonstrate that quantum dynamics, gravitational curvature, measurement theory, and modular collapse are fully compatible and mutually reinforcing within the χ‑spectral operator framework. The theory achieves conceptual and mathematical closure: all physical observables remain bounded, all transitions remain unitary, and quantum–gravitational consistency is established as a direct consequence of χ‑spectral geometry.</jats:p>
