Amazing work! In https://rember.com the main unit is a note representing a concept or idea, plus some flashcards associated to it, hsrs would fit perfectly! I'll look more deeply into it.
yeah! hsrs elements are the notes, and their learnable properties would be the flashcards.
however, individual grammar outputs aren't their own cards, you get a fresh example every time you see a card. this requires a very different scheduling approach, since you have to estimate how all the cards in the 'call tree' contribute to the overall result and reschedule them as well https://github.com/satchelspencer/hsrs/blob/main/docs/overvi...
Pretty much all spaced rep systems except for Anki structure their data this way - an editable data atom with flashcards auto-derived from it, on template or otherwise.
