The passage around this formula

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