Test	What it does	Result
test_gradient_matches	The analytic gradient agrees with a central finite difference of the explicit objective to 1e-3 relative along four random Hermitian directions.	✅ pass
test_matches_numpy	The reduced objective agrees with an explicit construction of the Kraus image to 1e-12.	✅ pass
test_objective_bracketed	The perturbed relative entropy stays between zero and ${\log }_{2}4$ bits times the pass probability, at three excess noises with and without postselection.	✅ pass
