A transparent MVP schedule

Short intervals first, longer intervals after success.

A new flag returns after ten minutes when recalled. Continued success moves it to one, three, seven, twenty-one, and then forty-five days. “Again” makes it due now; “Hard” keeps the current mastery and returns it in ten minutes.

This is a simple, testable product rule, not a claim of scientific optimality. The schedule can be tuned after real review behavior is measured.
