1// nx_sim_validation_real_gate.nx -- REAL-WORLD-DATA validation (not an analytic referent): the kind regulated / 2// military / AAA-game physics actually uses -- comparison to PUBLISHED MEASURED data. We do NOT need a lab we run; 3// published experimental measurements ARE the validation referent, and NASA-STD-7009 makes Level-3 (quantitative 4// comparison to real-world measurements) the legitimate PRE-DEPLOYMENT maximum (only L4 needs the actual deployed 5// system). Sim = Kepler's 3rd law T=sqrt(a^3) (AU/yr, GM_sun normalized) via our sovereign isqrt; it predicts each 6// planet's orbital PERIOD from its MEASURED semi-major axis, and we validate against the independently-MEASURED 7// period for ALL 8 planets (Mercury..Neptune, ~78x range). Liar-kill: a wrong law (T ~ a) deviates massively from 8// the real data. This lifts Validation from methodology to quantitative real-data validation (L3).
