Test	What it does	Result
test_below_asymptotic	THE SANITY PROPERTY. The finite rate never exceeds the same-parameter asymptotic rate at any block size, basis bias or error rate.	✅ pass
test_bias_optimum	The basis bias has an interior optimum: 0.95 beats 0.7 beats the uniform third, and 0.999 starves the monitor bases to zero.	✅ pass
test_block_shrinks	The rate falls as the block shrinks and is exactly zero at 1e5 signals, never negative.	✅ pass
test_rate_converges	MEASURED CONVERGENCE. The rate per sifted signal rises onto the asymptotic secret fraction, the gap falling over ninefold per two decades of block to 1.634e-8 at 1e22.	✅ pass
test_sift_accounting	The block splits by the paper's three-basis sifting, $b^2$ to the key basis and $((1-b)/2{)}^2$ to each monitor basis, mismatches discarded.	✅ pass
test_threshold_holds	At and above the 12.6% asymptotic crossing the finite rate is zero at every block.	✅ pass
