Test	What it does	Result
test_one_violation	pairs.rs's $2\sqrt{2}v$ and ekert.rs's four-term correlation sum at Ekert's angles agree in magnitude under opposite sign conventions, and ekert_qber inverts back to $Q=(1-v)/2$.	✅ pass
test_third_basis_pays	On the same observables six-state never returns less key than BB84, and at least 0.24% more wherever BB84 distils, so the ordering is no shared clamp at zero.	✅ pass
