# Self-test. Runs the action against test/fixture with dry_run: true, so it
# exercises every step — including the real rattler-build conda build — without
# uploading anything.
#
# Run this green before moving the v1 tag. Consumers are pinned to a moving
# major tag, so a bad push breaks all of them at once.
