    - `archs` Architecture[], required — List of supported architectures.
      - union
        - 'aarch64' | 'arm64' | 'x86_64' | 'universal' — An architecture known as of this snapshot of the API document. This is distinct from `Architecture` to allow parsing unknown architectures. Parsing unknown architectures is important to avoid a new architecture causing a major API break.
        - string — The raw architecture name, a fallback for when an unknown architecture is received.
    - `checksum` string — SHA-256 Checksum of the static SDK, if this platform is the static SDK.
