Split the states that are not task states (but are retry states) into there own additional set and then use that set and a new function to validate the transition at other locations in the code-base. This makes the transitions that are valid for tasks/retries easily viewable, more easy to read and understand, and more correct (instead of being a mix of task + retry atom transitions and states).
