# 0G publishes each network from a DIFFERENT repository, and the release-tag format is not
# consistent within either of them. The asset filename is always "<spec>-v<version>.tar.gz";

#
# aristotle -> 0gchain-Aristotle 1.0.4 = "1.0.4" 1.0.6 = "v1.0.6"
# galileo -> 0gchain-NG 3.0.3 = "v3.0.3" 3.0.7 = "galileo-v3.0.7" 3.0.8 = "v3.0.8"
#
# So the tag cannot be hardcoded. Resolve it by trying the known forms in order and taking
# the first that actually yields the asset.
#
# curl uses -f (fail on HTTP error). Without it a 404 HTML body is written into the .tar.gz
# and the build dies several layers later at "tar: not in gzip format" -- an error that
# points nowhere near the real cause. That has cost three separate misdiagnoses.
