duo-memory-and-decay
Decide when to bring something back in front of a user, and treat every capability they have as quietly rotting rather than banked. Covers spacing versus massing at equal cost, per-item half-life scheduling instead of fixed interval ladders, retrieval versus re-exposure, delayed retries, error-driven practice queues, graded decay, reactivating lapsed users without resetting them to zero, visible decay states on completed things, sleep consolidation, context variability, and making forward motion do the reviewing. Use when asked how long until users forget this, when to resurface an item, why a re-test passes while real retention does not, how to win back a lapsed user, why a completed badge goes stale, or how to design a review or practice mode. Difficulty targeting and ability estimation are a different model and belong to the difficulty-calibration skill.
