// Scenario (SCN-upload-optional-asset-failure):
//   Thumbnail and .torrent uploads are non-fatal, but their failures used to be
//   swallowed (warn-only) so the user got a silently-missing asset
//   (Cloudflare-upload audit #5).
//   Given a video upload where the thumbnail AND torrent uploads fail,
//   When uploadVideo runs and the note still publishes,
//   Then the user sees a 'warning' status for each failed asset, and the final
//     success status is a 'warning' that names what failed.
//
// Anti-cheat: drives the real uploadVideo control flow with the per-asset upload
// made to fail by content type; asserts the externally observable status events
// (message + variant), not internals.
