Analysis reveals distinct mass regimes for neutron stars and black holes, suggesting new insights into compact object dynamics.
Description: Updated phase diagram of compact objects in the CCEGA framework [G_eff(ρ) = G_N exp(−ρ/ρ_c), ρ_c = 7.4 ρ_nuc]. Three regimes: neutron stars (M < 4.56 M_sun), ultracompact horizonless objects (4.56–12.0 M_sun), CCEGA black holes (M > 12.0 M_sun). v2.1 adds GR consistency check: low-density limit recovers M_OV ≈ 3.30 M_sun (Oppenheimer–Volkoff), confirming CCEGA → GR for ρ ≪ ρ_c. Radion contributions quantified: 3.30→4.56 M_sun (NS support), 3.30→12.0 M_sun (black star formation). Version: 2.1
