about
nx_sim_uq_gate.nx -- climb the UNCERTAINTY QUANTIFICATION axis (NASA-STD-7009 "Results Uncertainty"; ASME V&V
20 / FDA all require UQ). A sovereign Monte-Carlo uncertainty-propagation engine, VERIFIED against the exact
analytic propagation law. Sim: projectile range R = (2*vy/g)*vx = k*vx (k=5 with vy=10,g=4). The horizontal
launch speed vx is UNCERTAIN: uniform over integers [mu-W, mu+W] (analytic variance W(W+1)/3). MC samples vx,
runs the sim, and the OUTPUT distribution must satisfy the analytic law: E[R]=k*mu, Var[R]=k^2*Var[vx]. The
sigma interval uses our sovereign isqrt. Liar-kill: with an uncertain input the output variance is provably
> 0 -- a "certain/deterministic output" claim is rejected. Deterministic PRNG (reproducible). GREEN iff 6/6.
