Test	What it does	Result
test_hajomer_key	Hajomer's trusted receiver (heterodyne eta=0.68, v_el=0.06272 SNU, beta=0.925) on the assembled budget gives ~2.7e-3 bit/symbol, above their finite-size 2.54e-4 and within a factor of 5 (not 2: chi_het/T ~ 74 SNU at T=10^-1.54) of 0.0117, derived not printed from Pietri et al., Quantum 8, 1575 (2024), arXiv:2404.18637, 1.17 Mbit/s asymptotic over 25 km at 100 MBaud.	✅ pass
test_hajomer_xi	Hajomer 2024 100 km LLO (arXiv:2305.08156), V_mod=8.41 SNU, T=10^-1.54, 16-bit DAC/ADC: the Bob-plane xi brackets their 2.12e-4 SNU within a factor of 3, on a fit against the literature form at v_err=7e-4 rad^2, RIN -155 dBc/Hz, B=100 MHz, ADC ratio 10.	✅ pass
test_metro_envelope	The default 25 km metro link (V_A=5, T=10^-0.5, v_err 2e-3 rad^2, 16-bit DAC, 12-bit ADC, RIN -155 dBc/Hz, B=100 MHz) assembles an input-referred xi inside the measured envelope [0.005, 0.03] SNU, phase dominating.	✅ pass
