   * Represents a single artifact.

   * <p>An "artifact" is an entity in object storage, file storage, or block storage. Artifacts should
   * be able to be stored in-memory as a single byte array. Implementations with an underlying type
   * that only supports streaming should stream in the full contents and make the full contents
   * available.
   *
   * <p>Implementations should remain read-only. Writing artifacts should be left to the
   * responsibility of a {@link ArtifactClient} implementation. If an object of the artifact type
   * returned allows writing of any type, then it should not be made available.
