This paper develops the Universal Resonance Orbit Equation in USP Field Theory as a calibrated slope-and-path framework for orbital motion, photon deflection, atmospheric retention, and spiral capture. The central idea is that a massive body can be represented as a three-dimensional resonance funnel. A perfect orbit is a closed Delta-f corridor on that funnel, where inward slope and angular motion balance. A precessing orbit is a nearly closed corridor with residual phase mismatch. A spiral path is a leaking corridor, where energy, angular momentum, drag, radiation, tidal exchange, gravitational-wave loss, or a declared residual channel causes inward or outward migration. A photon follows the optical or eikonal version of the same transverse-gradient geometry. The core operational mapping is written in text form as: PsiUSP = alphag (Delta fₚroxy - Delta fᵢnfinity) aUSP = -grad PsiUSP v² / Rc = |gradₚerp PsiUSP| For circular or nearly circular orbits, the path condition becomes: vₒrb (r) = sqrt r dPsiUSP/dr The stable-orbit condition is expressed through the effective potential: Psiₑff (r) = PsiUSP (r) + L²/ (2r²) dPsiₑff/dr = 0 d²Psiₑff/dr² > 0 This paper is not a replacement for Newtonian gravity, General Relativity, standard celestial mechanics, lensing theory, hydrostatics, or atmospheric physics. Standard gravity remains the predictive baseline. USP Field Theory is used as a resonance-geometry interpretation layer, and any USP-specific residual must be predeclared, calibrated, bounded, and tested against independent data. Version 1. 1 strengthens the calibration discipline. Every numerical use of Delta fₚroxy must declare the proxy formula, units, measurement channel, uncertainty, baseline model, residual template, and validation dataset. The document also includes canonical residual templates, a preferred residual hierarchy, source-term reporting rules, photon achromaticity guardrails, atmospheric layer interpretation, validation requirements, and predeclared falsification criteria. The paper’s central visual model is the 3D resonance funnel: closed orbits are stable rims, spiral paths are leaking corridors, and photon bending is the optical version of transverse slope curvature.
