"Riemann Hypothesis Numerical Experiment: Zeros on the Critical Line (t<=80)"

Numerical experiment data package for the Riemann hypothesis. Computes the first 21 nontrivial zeros of the Riemann zeta function on the critical line Re(s)=1/2 using pure Python (eta series + analytic continuation + bisection). All zeros verified against authoritative values (max deviation 0.005). Distribution statistics of zero spacings show GUE-type structure (variance 0.092, small-spacing repulsion), supporting the Hilbert-Polya direction. This is an evidence-chain result, NOT a proof (see HONESTY.md). Fully reproducible with only the Python standard library.
