CleanCache was off, so nothing ever pruned /var/cache/pacman/pkg - 23 GB on the machine this was found on, with three 3.2 GB copies of one package. Trimming only drops older versions of installed packages and cached versions of uninstalled ones, so the cost is downgrade depth, not working software. flatpak uninstall --unused moves from CleanCache to RemoveOrphans, where it belongs: unused runtimes are the Flatpak equivalent of orphaned packages, and removing installed software should not hide behind a flag named for cache trimming. RemoveOrphans stays off - 'orphaned' only means nothing depends on it, which is also true of something installed deliberately. The log now reports what a trim reclaimed, since a real paccache run says almost nothing and there was otherwise no way to tell it was working.
