Part V 1.1 TOV Integration Code: GR vs CCEGA Numerical Comparison

[Correction note, April 2026]: M_max values in this paper (theoretical 4.26, numerical 4.35 M☉) predate high-resolution verification in P34 v2.0, which established M_max = 4.56 ± 0.03 M☉.

Abstract

[Correction note, April 2026]: M_max values in this paper (theoretical 4.26, numerical 4.35 M☉) predate high-resolution verification in P34 v2.0, which established M_max = 4.56 ± 0.03 M☉. G_eff(I) = GN/(1+I) is an exploratory information-driven formulation; the canonical CCEGA coupling is G_eff(ρ) = GN·exp(−ρ/ρ_c) (P43 v1.1). The numerical code is reproducible and convergent (15/15) but implements an ad hoc coupling not derived from first principles. Part V remains valid as independent numerical motivation predating the rigorous DBI derivation in P43 v1.1, analogous to Kepler before Newton. See P34 v2.0 (doi:10.5281/zenodo.19766662) and P43 v1.1 (doi:10.5281/zenodo.19394258).Note: The numerical code is reproducible and convergent (15/15) but implements an ad hoc coupling G_eff(I) = GN/(1+I), not derived from first principles. It serves as independent numerical motivation predating the rigorous DBI derivation in P43 v1.1.
