## Scheduling new roots and reviews

I built spaced repetition into the daily emails so earlier roots would return alongside new material. The intervals increase through one, two, four, eight, and progressively more runs. Each learner needs a separate schedule because the roots they have seen and their last review dates differ. A saved progress record lets the job select one unseen root alongside any reviews due that day, before generating the lesson.
