 The runtime distribution is wheel-only. The release pipeline publishes three platform wheels with the pure SDK wheel: Linux x64, Linux arm64, and macOS 14 or newer on arm64. A `python-v<repository-version>` tag is accepted only when it matches the repository version; prerelease repository versions such as `0.0.1-rc.1` use their normalized PEP 440 spelling, such as `0.0.1rc1`, inside wheel filenames and metadata.
