Toward QMU Gravitational Field Equations II: Closure-Flow Conservation, Propagation Dynamics, and the Newtonian Projection Limit

This paper develops the second stage of the QMU gravitational field-equation program. Building on the prior geometrical framework of rotational propagation density, closure flow, and chronovibrational compression, the present work derives the first dynamical field structure from the Quantum Measurement Units (QMU) ledger. The paper treats gravity as a closure-flow propagation system within rotational Aether geometry. Closure-flow conservation is used to derive the Newtonian inverse-square projection, while time-dependent closure redistribution leads to a propagation-density wave equation. The analysis further develops nonlinear closure dynamics, propagation-speed compression, harmonic generation, closure-boundary impedance, chronovibrational field coupling, and rotational torsion transport. The Newtonian acceleration law is expressed in QMU form as \[g(r)=\left(\lambda_C {F_q}^2\right)\left(\frac{M}{m_a}\right)\left(\frac{{\lambda_C}^2}{r^2}\right),\] showing gravity as the SI projection of spherical closure-flow conservation. The paper also introduces the chronovibrational coupling relation \[F_q'=F_q(1-\chi_g),\] which connects propagation-density loading to clock-rate variation and gravitational redshift behavior. The resulting framework supports scalar gravitational modes, longitudinal closure oscillations, torsional propagation transport, nonlinear closure harmonics, and tensor reconstruction as an emergent SI projection layer of deeper QMU closure-flow geometry.
