nx_sim_repro_h2h_gate.nx -- MEASURED head-to-head to earn the Reproducibility/Determinism axis EXCEEDS(4)
(charter: EXCEEDS must be a measured head-to-head, never self-scored). The decisive, sovereign demonstration of
WHY the no-float law gives us reproducibility 3rd-party float sims can't match: IEEE-754 float addition is
NON-ASSOCIATIVE, so summing the SAME values in different orders yields DIFFERENT bit patterns (and here a WRONG
answer), while our INTEGER arithmetic is associative -> bit-identical in every order AND correct. We use the
real hardware f32 (addss via nx_f32_hw) ONLY as the negative baseline; the sim itself stays integer/no-float.
MEASURED: distinct-results(float) >= 2 vs distinct-results(integer) == 1. GREEN iff 6/6. license_tier: ORIGINAL
