""" verify_P179.py — G1 = 1728/pi^3 - 1 : Chowla-Selberg investigation ======================================================================= Investigates whether G1 = j(i)/(4*OMEGA_0) - 1, where OMEGA_0 = pi^3/4 (TOE kernel constant) and j(i) = 1728, has structure within the Chowla-Selberg frame of Gamma-function values at rational arguments. Steps ----- 1. Compute G1 = 1728/pi^3 - 1 to 50+ significant digits. 2. Compute the Chowla-Selberg / CM period ingredients: Gamma(1/4), Gamma(3/4), lemniscate constant ϖ, real period ω₁, ALPHA_INV, BREATH_PERIOD. 3. Run PSLQ over multiple bases of increasing size and coefficient bound. 4. Test candidate closed-form expressions analytically. 5. Test the Ramanujan q-expansion approach. 6. Report: "G1 in Chowla-Selberg frame: YES/NO". All arithmetic at mp.dps = 55 (≥ 50 guard digits). L. F.
