TestWhat it doesResult
test_gain_orderingAt an equal sifting factor the six-state rate beats BB84's on GYS by 1.14856x at 0 km and 2.9694x at 140 km, the ratio growing with loss.✅ pass
test_gys_pointGYS at 25 km gives 5.77121e-4 through the Y1 and e1 bounds BB84 consumes, and decoy_bounds' vacuum-plus-weak inversion feeds sixstate_rate at a cost in rate.✅ pass
test_reach_longerOn GYS the six-state reach is 146.1986 km against BB84's 142.2085 km, a gap of 3.9901 km, each pin carrying key and reading exactly zero a metre out.✅ pass
test_sift_costUniform three-basis sifting costs more than the tighter bound buys until 132.578 km.✅ pass
