This is the piece that catches a lesson in the first 24–48 hours, before the forgetting curve gets steep — a same-day and next-day recall check, separate from the longer Leitner-box cycle running on the practice sheet.
Planned shape
Same-day micro-check — a couple of minutes, right after finishing a lesson, no notes. Catches whether it landed at all before you move on.
Next-day micro-check — the same concept, cold, 24 hours later. This is where most first-encounter forgetting happens — surviving this is what earns a concept its way into the practice sheet's Leitner rotation.
Feeds into the Practice Sheet — once a concept survives both checks, it graduates into the box-based long-term schedule already running there.
