Unclear Whether asset_uploads replaces, supplements, or differs in meaning from the existing asset_upload scope is not shown by the evidence.

What

  • A new asset_uploads result type (alongside the existing singular asset_upload) supports uploading multiple files in one batch.
  • Each file in the batch is reported individually as uploaded (with id, url, size, content type, and sha256), failed, or not attempted, with a reason/message and an optional may_be_stored flag.
  • The UI now shows a summary line like "uploaded N of M files" followed by a per-file status list showing the URL, "not attempted", or "failed" for each file.
  • A new asset_uploads permission-scope entry was added alongside the existing singular asset_upload scope.

Why

This lets Artifacts upload several files in a single operation with clear per-file feedback, instead of requiring one upload call and result per file.
