# Upload release assets to a GitCode release.
#
# The endpoint shapes are asymmetric and both differ from the "obvious" guess:
#
#   GET  /releases/tags/{tag}            → read a release
#   GET  /releases/{tag}/upload_url      → get a presigned PUT   (NO "tags/")
#   PUT  {presigned url}                 → upload, REPLAYING the headers verbatim
#
# Two mistakes cost real time on v1.9.5 before this script existed:
#
#   1. POSTing straight to /releases/{tag}/assets returns 404 — that endpoint
#      does not exist. It reads as "authentication failed" if you only check
#      the status code.
#   2. PUTting without the headers fails with an opaque storage error, not a
#      permission one, so it looks like a size limit or a corrupt file.
#
# The x-obs-* headers are part of the signature: dropping any one of them turns
# the request into an unsigned one.
