                    The actions the classifier may recommend for a mail. These rows drive the AI prompt, the
                    Next Action column on the mail list and the Next Action filter menu.
                    The list is shared by everyone — an action an administrator adds here is recommended on every
                    user's mail, not just their own.

                        A mail gets exactly one action. The order above is the order the AI sees, and it is told to
                        prefer the action nearest the top when more than one fits — so this list is the urgency
                        ranking: put "drop everything" at the top and "nothing to do" at the bottom.
                        Changing an action affects mail classified from the next pipeline run onward, for every
                        user; mail already processed keeps the recommendation it was given.
