Test	What it does	Result
test_pairs_accidentals	Their Eq. (11) accidental QBER ${\mu }_t/(2(1+{\mu }_t))$, 1.923% and 6.140%, sits 2.2% and 5.8% above Ma, Fung and Lo's Eq. (10) at zero misalignment and background.	✅ pass
test_pairs_assignment	Their singles put the 2.0% detector on the signal arm: 33.3 and 12.7 kcps against ~36 and ~11, the swap 14.5x worse.	✅ pass
test_pairs_bounded	qkd's Shor-Preskill pair_rate keeps 94.8% of their Waks-Zeevi-Yamamoto individual-attack fraction at 0 km and 86.8% at 100 km.	✅ pass
test_pairs_deficit	Declared miss: their sifted rate falls 51.6x between runs against the model's 31.3x, 0.773x their 29.4 bit/s at 0 km and 1.275x their 0.57 at 100 km.	✅ pass
test_pairs_losses	Their itemised receiver chain plus the "~10.5 dB" spool, exactly 0.21 dB/km over 50 km, rebuilds their "~17.4" and "~17.0" dB totals.	✅ pass
test_pairs_qber	One misalignment fitted to their 2.35% back-to-back QBER predicts 6.702% at 100 km against their 6.91%, across 21 dB.	✅ pass
test_pairs_visibility	Their raw two-photon visibilities predict the energy-basis QBERs through $e=(1-V)/2$: 3.100% against 3.1% at 0 km and 7.500% against 7.59% at 100 km.	✅ pass
