Finite-Time Accessibility of Stochastic Futures: Figure Data and Reproducibility Package

This dataset contains the figure-source data, numerical validation records, provenance information, and reproducibility materials supporting the manuscript “Finite-Time Accessibility of Stochastic Futures.” Version 3 preserves the complete source-data and validation package for Figs. 1–4 from Version 2 and adds controlled mechanism-perturbation tests supporting Supplemental Figs. S4 and S5.The added data quantify (i) the response of fixed-event accessibility to controlled changes in the activated-barrier parameter and (ii) shifts in discrete state-opening thresholds under controlled changes in the energy-landscape curvature. These perturbation tests are intended as bounded sensitivity checks: they demonstrate reproducible mechanism-dependent responses under the specified models and protocols, but do not establish unique inverse identification or a universal response law.The accompanying README, data inventory, figure–data–claim map, and SHA-256 manifest document the relationship among source data, derived quantities, validation outputs, figures, and manuscript claims. No numerical data were reconstructed or digitized from figures.
