Spaced repetition
Spacing reviews helps organize returns to material; in Fluorgan it stays tied to real answers and low-evidence states.
Core idea
The interval changes with stability, history, perceived difficulty, lapses, and study context.
Use in Fluorgan
The scheduler decides next reviews from persisted memory. Forecast and prediction remain labeled as prediction.
