Test	What it does	Result
test_angles	Alice's four Bloch angles are the modulated phases theta*(1 + delta/pi).	✅ pass
test_extremes	The triangle is 2 at zero flaw, peaks at 3 sqrt(3)/2 where the three states are equilateral, and vanishes as the flaw reaches pi.	✅ pass
test_fidelity	The two-basis fidelity is the Uhlmann fidelity of the Bloch vectors, and is exactly one at zero flaw.	✅ pass
test_triangle	The triangle determinant equals 2 cos(delta/2) + sin(delta) in closed form.	✅ pass
test_virtual	The two virtual X-basis states carry priors (1 -+ sin(delta/2))/2 and are exactly antipodal.	✅ pass
