Data and analysis code for "From salt-in-water to water-in-salt: the emergence of glass-like dynamics and the transference number controversy"

This Version 2 expands the original record with processed numerical datasets, selected simulation inputs and Python analysis and figure-generation code supporting the associated article. The materials are organized by article figure and include water oxygen-oxygen radial-distribution data, four-point susceptibility and structure-factor outputs, pair-excess-entropy and dimensionless reduced-diffusivity data, and density and viscosity force-field validation tables. The accompanying README files document filenames, columns, units and reproduction steps, and SHA-256 checksums are provided. The experimental comparison values used in Figure 5 were taken from Gilbert et al. (2017; https://doi.org/10.1021/acs.jced.7b00135) and are clearly separated from the molecular-dynamics simulation results. Associated article: https://doi.org/10.1098/rsta.2025.0283
