Well, it was probably wide open only for me. And I finally sort of understand what is going on ... maybe. I think this is what was going on:

My intent, too, was to provide a share safe from ransomware, but that did not happen since the "secured" share was open for me all the time.
Now I've messed things around enough that I can't access the secured shares at all, but I can access the public shares without providing credentials.
