# Scenario: paccache -rk3 trims an installed package's cache to 3 versions.
#
# paccache decides from filenames, so five fake versions of a package that
# IS installed (bash) stand in for a fat cache. The bootstrap may leave a
# real bash package in the cache too, so the assert uses the ordering
# invariant rather than a count: the two newest fakes survive any keep-3
# window that contains them, and the two oldest fall outside it whether or
# not a real (newer) version is cached alongside.
