7/7 passed in 1ms

Test	What it does	Result
test_enzer_crossover	Six-state overtakes BB84 at 8.340% with nothing fitted, inside their "below ~8-10%".	✅ pass
test_enzer_dead	BB84 yield dies at 11.003% and six-state at 12.619%, both inside their "greater than 10-15%".	✅ pass
test_enzer_detection	The secret fraction is 0.7883 at their undisturbed 1.7%, zero under intercept-resend for every key basis, and 0.3901 under the partial attack at strength 0.22.	✅ pass
test_enzer_intercept	Intercept-resend in any linear basis gives l1 = 1/2, a six-state BER of 33.333% against their 34.0 +/- 1.4% (0.48 sigma), and BB84 25.000% against their 25%.	✅ pass
test_enzer_partial	Their partial attack's 11%/7% = 1.571 against 3/2 at any strength, the fitted strength reading 0.22 from the peak and 0.21 from the average, with l4 = 0.	✅ pass
test_enzer_sifting	Declared miss: 55 650 sifted bits over 94 min at 33 s^-1 is 29.900% of events against sixstate_sift's 1/3, a 10.3% deficit.	✅ pass
test_enzer_spread	Per-basis error rates span 0 to 50% against their "~0 to 50%", with a peak-to-average ratio of 3/2.	✅ pass
