Pattern recognition review: after the primer. Each daily ritual includes a pattern cue.

Independent recalls return after 1, 3, 7, 14 and 30 days. Delayed evidence needs at least 24 hours. Hints keep the next review close; they never pretend to be mastery.

One rest day can bridge your streak in a rolling seven-day window. Rest days are never counted as practice.

Your first weekly marker appears after you practice. Nothing is prefilled.
