ManifestFromRemote captured presigned blob URLs for every layer before any downloading began; on images with large layers the URLs for later layers expired (typically after 10 minutes) before the fetcher reached them. Store the registry's stable blob URL instead and hand the authenticated transport to the fetch arena, so each layer GET authenticates fresh and follows the storage redirect immediately.

To do this, you need add the auth headers. The point of "resolving" the URL is to not have to do that, but it does start any URL auth timer ticking when that's done.
