Computational Evidence for Ramanujan's Unsolved Problems: Stable Structural Constant in Mock Theta / BPS Black Hole Analysis

Computational evidence bearing on four of Ramanujan's open problems produced by Corriente LLC's autonomous QSim engine over 36+ hours. Primary finding: stable structural constant 2.4914 identified by Amara (black hole IA) in the Cardy formula accuracy ratio between mock theta coefficients and BPS black hole entropy predictions, confirmed across 600,000+ independent computation loops. Brocard-Ramanujan verified to n=209,208. Newman's conjecture verified for moduli 2-15. Lehmer's conjecture verified in exact polynomial range. Dedicated to Srinivasa Ramanujan (1887-1920).
