| Test | What it does | Result |
|---|---|---|
test_estimator_narrows | Over sixteen times the symbols the spread of the T estimate narrows between 2.5 and 8 times, measured 4.2 to 5.6 against the square-root law's 4.0. | ✅ pass |
test_estimator_unbiased | With noiseless lasers and a 30 dB pilot the estimated T and xi sit within five standard errors of the simulated channel from 25600 to 409600 symbols; at the 12 dB default xi is biased by +1.2e-2 SNU. | ✅ pass |
test_pilot_leaks | The pilot leak xi_hat - xi_ideal divided by 10^(-pilot_db/10) holds 0.155 SNU to 2.6% at pilot depths 3, 6 and 9 dB, asserted to 7%. | ✅ pass |
test_rate_converges | Trusted homodyne cv_rate on the estimates lands within three standard errors of cv_rate on the truth at 409600 symbols. | ✅ pass |
