Function merged 

pub fn merged(
    open: &[Note],
    dataset: &[Note],
    view: &[Note],
    schema: Option<&DatasetSchema>,
) -> Vec<Note>

Every note the panel shows (the open’s, the footers’, the view’s), with the one fact the first two both report said once: a mixed directory’s skipped files appear in the open’s note and the footer walk’s. The open’s sentence is kept; the walk’s is rebuilt without those files, keeping skips only it saw.
