The passage around this formula

The program first reproduces published overlap or decoherence curves inside their stated regimes. Only then does it calculate D , pep_{\rm e} , χH\chi_H , IdecI_{\rm dec} , and threshold times. A separate finite-time module approximates the admissible-future optimization needed for DirrD_{\rm irr} . Its result is labeled exploratory until it reproduces benchmark purification cases from the 2025 work.
