What

When an artifact consists of a single page with no separately published files, the response to a file-list request (which previously just noted there's no file list to return) now also includes the artifact's ver (version), cowritten, and typeLocked fields.

Why

This gives more context about a single-page artifact directly in the file-list response, such as its version and whether it was co-authored or has its type locked, without needing a separate request.
