Repair an inconsistent porous-volume characterization
A porous-media research group is reprocessing segmented X-ray tomography data from sandstone with this historical PoreSpy source snapshot. The supplied offline workflow completes normally, but the summaries produced from the supplied segmented volume and an explicit axis-permuted representation of that same volume are not mutually consistent. A radial two-point characterization should not depend on which array axis stores a physical direction.
Run the reproduction, inspect the supplied sample data and project source, and repair the implementation so the scientific characterization is consistent with the definitions supported by the project. The repair must generalize to other valid segmented images and documented analysis options.
Do not hard-code the supplied volume, permutation, any public observation, fixed dimensions, or filename-specific behavior. Do not modify the scientific input, workflow, public observations, or generated reports.
