The Frostyverse: Discrete-Grid Candidate for Perihelion Precession, Fourfold Response Multiplicity, and Two-Body Orbital Dynamics

The Frostyverse is a speculative discrete mechanical model in which local propagation and gravity-like response occur through a deformable three-dimensional FrostGrid. In simple terms, this paper asks whether the same underlying Frostyverse orbital mechanics can describe both a planet orbiting a much more massive body, such as Earth around the Sun, and a more balanced two-body system, such as Earth and the Moon. The results show that the same orbital-response framework can be used for both, while also identifying a structural candidate for the additional response associated with perihelion precession. The mechanically derived orbital-response scale is denoted by D. The tested Frostyverse mechanics produce a stable orbital response near 2D. After that Frostyverse basis was sealed, General Relativity was opened only as an external comparison ruler, identifying a remaining weak-field precession response near +4D. Subsequent FrostNode/FrostCell audits found an exact fourfold node-local response-context multiplicity while independent conservation tests showed that one complete FrostTransit handoff retains only one D-scale conservative work ledger. The publication interpretation is therefore one D-scale conservative handoff acted on by a fourfold structural response multiplicity, yielding an effective +4D response rather than four independent energy copies. With the structural factor frozen before comparison, the R80 Frostyverse prediction for Icarus was 10.0628774619 arcsec/century; the subsequently opened GR-like comparison was 10.0630890913 arcsec/century, a relative difference of approximately -0.002103%. A separate Frostyverse-only mass-ratio stress through equal masses favored the pair-total rule M_pair = M1 + M2, used consistently in both the effective field and relative-orbit calculation. The accompanying reproducibility package provides reviewer-facing Python programs for the precession calculation, two-body mass-rule test, and fourfold structural-response audit, together with historical provenance and SHA-256 verification data. These results constitute a computationally constrained Frostyverse candidate, not experimental validation and not a proof of equivalence with General Relativity.
