# Restore the MergeBench artefacts from the Hub copy after a working-tree loss.
#
# We have published additively all night, so the dataset repo is the authoritative backup. This
# downloads it to a staging directory and reports what is there; it does NOT overwrite anything by
# itself -- the caller decides what to put back, because a partially-restored tree that then gets
# republished is how good artefacts become degraded ones.
