Test	What it does	Result
test_naik_bridge	The bridge Q = (1 - |S|/2sqrt2)/2 maps the mean of S and S' to 3.0746% against the measured 3.06 +/- 0.11% (0.13 sigma), S and S' alone bracketing it at 1.55 sigma below and 1.82 above.	✅ pass
test_naik_eavesdropper	The same bridge gives exactly 25% BER at Ekert's |S_eve| <= sqrt(2), and (2 - sqrt2)/4 = 14.645% at S = 2, an intercepted share of 58.579% against their 58.6%.	✅ pass
test_naik_margin	Their 3.06% sits 4.09 points inside the CHSH-priced zero of 7.149% and 7.94 inside the characterised-device 11.003% of their note [30].	✅ pass
test_naik_modern	Declared miss: their 24.551% EC leakage (1.244 times Shannon) plus the CHSH price leaves 10 009 bits, 64.8% of their published 15 444.	✅ pass
test_naik_price	The collective-attack CHSH price on their violation is 0.34178 bit per raw bit, 2.90 times the 0.11768 their privacy amplification charged.	✅ pass
test_naik_sifting	24 252 raw bits from 40 pairs/s over 2400 s is 25.263% of pairs against their table I's 1/4, and 10.105 bit/s against their 10.1.	✅ pass
