Solutions

1. Skip zero-byte files in your upload/sync job targeting Baidu Youth
2. Write a 1-byte placeholder if an entry must exist
3. Handle this sentinel (errors.Is) as a skippable condition in batch transfers

Example fix

// before
err := d.Put(ctx, dst, stream)
// after
if stream.GetSize() == 0 {
    return errs.NotImplement // or skip upstream
}

if stream.GetSize() == 0 { return nil }

err := d.Put(ctx, dst, stream, up)
if err != nil && errors.Is(err, ErrBaiduYouthEmptyFilesNotAllowed) { return nil }

When it happens

Trigger: Calling Put() on a Baidu Youth storage with a model.FileStreamer of size 0; the server-side API refuses empty file creation.

Common situations: Same as the main netdisk driver: syncing placeholder files, .gitkeep markers, or empty logs to a Youth edition account.
