# 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";
# only the tag varies:
#
#   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.

# Extract by DETECTING the layout rather than assuming one per chain. 0G has shipped
# three shapes so far and changed between them without notice:
#
#   galileo <= 3.0.3  <root>/{rpc,validator,archive,seed}/bin/ + configs   (168 MB)
#                     -> binaries duplicated inside every profile dir
#   galileo >= 3.0.8  <root>/bin/  shared, + <root>/{rpc,...}/ configs      (69 MB)
#                     -> binaries DEDUPLICATED to the tarball root; rpc/ is configs-only
#   aristotle 1.0.x   <root>/bin/ + configs, no profile dirs at all
#
# So "does <root>/rpc exist" is NOT sufficient: 3.0.8 still has rpc/, it just no longer
# holds bin/. Take configs from the profile dir when present, then top the binaries up
# from the shared root bin/ if the profile dir didn't supply them.
#
# The old code hardcoded "galileo -> mv <root>/rpc /0g", so 3.0.8 yielded configs but no
# binaries and the build died two layers later at
# `chmod: cannot access '/0g/bin/0gchaind'` — an error naming neither the chain, the
# version, nor the layout. Assert on the binaries here so the NEXT upstream reshuffle
# reports itself at the point of failure instead.
