	The user wants to call a function on entry to the main hubi transient.
	Looking at the transient-define-prefix hubi () definition, there isn't an obvious hook or slot to run a function when the transient is invoked.

	However, the user says "Can I call something once on entry to the main hubi transient to set values if they are in fact null - ideally by loading from dir locals."

	The problem is that .dir-locals.el are applied when a file is visited. If the user is in a buffer that is not visiting a file in the project (e.g. mu4e-headers), the dir-locals for that project won't have been applied. However, default-directory might point into the project.

	The user mentions a hack to hubi--show-compile that didn't work because they need to set defaults based on .dir-locals. This suggests that hubi--show-current-compile is a place where we could put some logic.
