Test	What it does	Result
test_t12_background	With nothing fitted, two dark gates at 2.1e-5 plus 5.25% afterpulsing on the u-line rate predict a 2.9465e-4 background against the 2.9493e-4 their w line measures.	✅ pass
test_t12_counts	The Z and X readings of each gain agree to 0.075% at u, 2.9% at v and 3.4% at w, where the minority-basis samples are 2.8e4 and 5.8e3 counts.	✅ pass
test_t12_decoy	decoy_bounds on their intensities gives a single-photon yield 1.09% under the infinite-decoy ceiling and phase error bounds above the true value in both bases.	✅ pass
test_t12_enhance	Declared miss: the modelled T12-over-BB84 gain at 50 km is 66.5% against their 73.0%, the model charging error correction on the noisier Z basis that carries 99.6% of T12's key.	✅ pass
test_t12_ladder	At 0.20 dB/km (2.84 dB on Bob's side) the asymptotic rate stays at or above their finite-key rate at all four distances, 1.560 times at 80 km.	✅ pass
test_t12_lines	The forward model calibrated at u predicts 7.633e-4 against a measured 7.537e-4 at v and 3.053e-4 against 3.056e-4 at w.	✅ pass
test_t12_misalign	Background is 71.9% of the 4.26% Z QBER and 84.0% of the 3.64% X QBER, leaving misalignments of 1.276% and 0.619%, X the cleaner basis as they state.	✅ pass
test_t12_rate	With $f(e)=1.0995$ fitted to the 50 km T12 rate, the $p_X=1/2$ row is predicted at 0.6546 Mbps against their 0.63.	✅ pass
test_t12_sifting	$p_X=1/16$ alone gives 11.72% discarded, 88.28% kept and a 76.56% gain over BB84's half, against their 11.7%, 88.3% and 76.6%.	✅ pass
