# Tests for install-lang.sh's bundle-completeness warning.
#
# Background: the python and typescript bundles shipped for nearly two months
# with no githooks/pre-commit, so any project installing them got no
# credential scan on commit. install-lang guarded each component copy with a
# plain `[ -d ... ]`, so a missing component was indistinguishable from a
# complete install — it printed nothing and exited 0.
#
# The fix is not "never miss a component" (a person will), it's "say so when
# you do". These tests pin that: a complete bundle installs quietly, an
# incomplete one names exactly what's absent, and neither case fails the
# install — a warning must not become a new way to block work.
