Evidence and provenance
Results keep their original context.
Figures come from repository snapshot e367fe5. Each case links to its report and, where available, the script used to reproduce the campaign. The execution version belongs to the original record. Showing a result on the current site does not mean it was rerun for release 0.2.11.
