# Invariant for the packages artifact that packages/core/installer pushes:
#
# `flux push artifact` REPLACES its built-in ignore list when --ignore-paths is
# given rather than extending it, so the flag's value has to carry the defaults
# as well. Dropping one of them re-admits a file class the artifact never
# shipped before, and dropping node_modules/ re-admits the dependency tree that
# `pnpm install` leaves under images/console: a single file above Helm's 5MB
# per-file limit makes the dashboard chart unloadable on every cluster that
# pulls the bundle ("decompressed chart file ... is larger than the maximum file
# size 5242880"), with nothing in the build reporting it.
#
# Requires: make. flux is optional and only used to re-check the defaults.

# The upstream defaults, as printed by `flux push artifact --help`. The second
# test holds this copy against the installed flux so an upstream addition is
# noticed instead of being silently left out of the artifact's ignore list.
#
# That second test needs flux, and the unit job has none, so it re-checks the
# copy only where flux is installed -- a developer machine, or a lane that
# installs it. It returns 0 rather than failing there, because a missing tool
# is not a broken invariant; the first test is the one that holds on every
# runner. `skip` is not available: hack/cozytest.sh is not bats and defines no
# such function, so calling it aborts the suite instead of passing over a test.
