Test	What it does	Result
test_bell_domain	Each error rate is refused outside [0, 1/2] one slot at a time, and a triple no Bell-diagonal state can produce is refused rather than clamped.	✅ pass
test_budget_domain	sixstate_eps refuses either epsilon outside (0, 1) and a correction term at or above the deviation it nests inside.	✅ pass
test_holevo_domain	sixstate_holevo refuses anything outside [0, 1/2], including a NaN.	✅ pass
test_pooled_domain	sixstate_pooled checks the triple it was handed, so a pair no Bell-diagonal state carries is refused even where its average would pass.	✅ pass
test_rate_domain	sixstate_rate refuses a vanishing sifting factor, a gain or error rate out of range, a below-Shannon f_ec, and an inverted decoy bound q1 > q_mu.	✅ pass
test_secret_leak	sixstate_secret refuses an f_ec below the Shannon limit.	✅ pass
test_sift_domain	The basis bias is refused below 1/3 and at 1.	✅ pass
