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 manifests supporting the manuscript “Finite-Time Accessibility of Stochastic Futures.” The deposited materials include Monte Carlo source data for activated Langevin first-passage dynamics, analytically evaluated probability-resolved frontiers for controlled diffusion, original state-resolved first-passage data for a local-detailed-balance Markov network, and the underlying data used for cross-model accessibility-frontier comparisons. Numerical convergence tests and thermodynamic-bookkeeping audits are also included. The data support protocol-conditioned, probability-resolved accessibility boundaries. The model-specific driving and control coordinates should not be interpreted as a universal entropy-production resource, and the deposited calculations do not establish globally optimized reachability or a universal thermodynamic accessibility geometry.
