v2 — Revised April 2026 Equilibrium radius re-derived from nuclear saturation density (approximately 2.3 × 10¹⁷ kg/m³), yielding Re ≈ 12.7 km and placing the object firmly in the relativistic regime (compactness C ≈ 0.23). The original master equation (Eq. 1) contained a dimensional inconsistency and has been replaced by a TOV-framed pressure balance. The resonant frequency mechanism is revised from an acoustic shell resonator to the fundamental toroidal Alfvén mode, grounding the 3.9 Hz prediction in magnetar-scale field strengths (B ~ 1.7 × 10¹¹ T) consistent with the proposed progenitor population. The Golden Mean (φ) has been removed pending derivation from a potential minimisation of the Israel junction condition. The Brown Dwarf analogy is replaced by a Magnetar progenitor framework with explicit pressure regime comparison. A section distinguishing the SSSR from the Mazur–Mottola gravastar by arrest mechanism, shell composition, and oscillation physics has been added.
