--platform is parsed as --platform=$2 and then shift 2 without validating that a value was actually provided. If someone calls the script with --platform but no argument, this will fail with a generic shift error rather than a clear usage message. Add an explicit check (e.g., ensure $# -ge 2 and $2 is non-empty) and print usage/exit when the argument is missing.

Suggested change

	if [ "$1" = "--platform" ]; then
	if [ "$1" = "--platform" ]; then
	if [ $# -lt 2 ] || [ -z "$2" ]; then
	echo "Usage: $0 [--disable-gssapi] [--platform <docker-platform>] <manylinux-docker-image> <output-path.tgz>"
	exit 1
	fi

This adds a linux/s390x runtime mapping, but packaging/nuget/packaging.py's magic_patterns currently has ELF checks for linux x64 and arm64 only. That means the s390x .so won't be validated for architecture during packaging, reducing defense-in-depth against accidentally bundling the wrong binary. Consider adding a corresponding magic_patterns entry for (linux, s390x, .so).

The workflow installs QEMU binfmt using tonistiigi/binfmt without a tag or digest, which makes the build non-reproducible and risks sudden CI breakage if the upstream image changes. Pin this image to a specific version tag or digest (similar to how the manylinux images are pinned).

Suggested change

	- docker run --privileged --rm tonistiigi/binfmt --install s390x
	- docker run --privileged --rm tonistiigi/binfmt:qemu-v8.1.5 --install s390x
