Design pages in this domain¶

Detection Sizing — the four laws behind one prefix — the four statistical laws behind one det_ prefix: which one a statistic actually obeys, why non-coherent looks raise their own threshold, and the 41x an estimated noise reference costs
Lock Detection — the reasoning — the sizing chain every lock detector shares, and the independence it assumes
