# Use a release binary instead of building from source

# The release version is verified by tools/scripts/publish-scip-ruby.sh
# The binary at this version is guaranteed to exist because this workflow runs either:
# 1. Manually with a specific tag that already has a release
# 2. After the Release workflow completes (which creates the release and uploads the binary)
