Physical Properties and Action Scales of Habitatons and the Electron Habitaton Cluster: A Habitat Information Physics Inference from Spherical Propagation to the Universal Gravitational Field

Habitat Information Physics (HIP) proposes a lower-level field model linking wave propagation, electron organization, object-boundary response, and inverse-square radial constraints. We represent spherical propagation by a fixed-area local slice of one-wavelength thickness and constrain an effective nearest-neighbor relation scale with a specified second-order discrete propagation model and cross-frequency dispersion limits. Under that model, d_hs^eff < 5.258159 × 10⁻²⁷ m. With the explicit one-link-one-habitaton identification, a 588.995 nm Na D₂ wavelength contains more than 1.120154 × 10²⁰ equivalent one-dimensional responses. Spherical allocation gives local mean action proportional to r⁻² and, when local action is proportional to amplitude squared, amplitude proportional to r⁻¹ without requiring a change in intrinsic propagation speed. The electron is defined as a localized coreless habitaton cluster; state reorganization, atomic-electron boundary separation, and candidate internal unbinding are assigned to distinct threshold layers. At the macroscopic level, whole-volume source integration, surface-boundary output, and external spherical distribution yield g_H = K_H/r² under weak-field, near-spherical, approximately universal receiving-boundary response. The Sun-Earth calculation reproduces the standard radial scale but is explicitly identified as orbit-inverted closure rather than an independent solar-interior prediction. Independent source-strength prediction, composition-universality tests, multi-source superposition, and blind recoil-closure tests define the falsifiable program.
