Test	What it does	Result
test_paired_observables	At all four distances the sifted share is 1/8 to 1e-3 and the single-pair share exp(-2 mu) to 0.008, while the modelled Z error sits under their QBER, pairing_sift taking no misalignment.	✅ pass
test_paired_pairs	Declared miss: pairing_click is 1.87-2.09 times Table VI's click probability and pairing_pairs 2.5-3.2 times its pairing rate, Zeng's symmetric source against Zhu's p_mu of 0.20-0.25, putting the end-to-end rate 2.3-14.7 times high.	✅ pass
test_paired_rate	On Table VI's pairing rate and e_ph_11 the key rate per pair is 0.84 and 1.03 of measured at 101 and 202 km, and 2.9 and 4.5 times at 304 and 407 km, where eps = 1e-10 bites on 4.51e6 and 6.02e6 single-photon Z-pairs.	✅ pass
test_paired_square	Table VI's eta is one side's, so the rate scales as eta to the 1.144 measured and 1.033 modelled over the two shortest rows and 1.894 and 1.576 over all four, all under the two-mode 2.	✅ pass
