pyproject.toml:13

• The static version '0.0.0' in the [tool.poetry] section may conflict with the dynamic version declared in [project]. Consider removing the static version field if dynamic versioning is intended.

version = "0.0.0"

portable.py:66

• The updated version check asserts that 'Version 0.0.0' is not present in the help output, which could mask issues with the dynamic versioning setup. Consider verifying the executable displays the expected dynamic version instead of a hardcoded placeholder.

"Version 0.0.0" not in subprocess.run(["dist/smpmgr/smpmgr", "--help"], capture_output=True).stdout.decode()
