Data and code for temperature-dependent nonlinear imbibition in rapeseed: a spherical Richards model for hot-soaking kinetics

Original replicate-level gravimetric measurements of rapeseed hot-soaking kinetics at 4, 15, 25 and 50 °C, with three independent aggregate batches and 18 measurement times per batch. The archive also contains Python source code for the spherical nonlinear Richards model, multitemperature calibration, empirical-model comparison, constitutive sensitivity analysis, numerical verification, internal-hydration endpoints and figure generation. Verified numerical caches and processed machine-readable outputs are included to support both rapid and full reproduction. Manuscript files, supplementary-manuscript files and generated figures are intentionally excluded.
