# The URL is the "download artifacts archive link"

#
# Note!  It is quite possible that this will break if the structure of
# the shadow tests in CI changes.  If that happens, you need to adjust this
# script and/or test code that uses this test data.
#
# (We could run this script in CI, detecting this situation, but then
# if adjustments are needed they would be blocking for improvements to
# the integration tests.  And then we'd want to rerun cargo tests in CI etc.
# It seems better to defer any such rework/adjustment until the test data
# needs to be refreshed for other reasons.)
