TestWhat it doesResult
test_block_monotoneThe length and the length per emitted packet both rise with the block, the two hash terms and the three thresholds all being amortised.✅ pass
test_double_priceObserved double clicks raise the multiphoton threshold and shorten the length.✅ pass
test_leak_independentChanging the bit error rate moves no threshold, so the whole change in length is the leakage fn_sift(h2(0.05) - h2(0.01)).✅ pass
test_length_unitsThe length is whole bits, never negative, and zero on a block too short to certify.✅ pass
test_rate_convergeCROSS-ENGINE. The length per sifted bit closes from below on 1 - f h2(e_bit) - h2(e_ph) at exponent -0.5006 over three decades from 1e9.✅ pass
test_sift_guardMore sifted bits than emitted packets is refused.✅ pass
