def self.expired(current_time: Time.current)
  where(["box > ? and next_review <= ?", 0, current_time])
end

.failed(current_time: Time.current) ⇒ Object

Lapsed (box 0, already reviewed) cards that are due now. A null next_review means “review immediately” (binary algorithms reset this way); a future next_review (e.g. SM-2’s one-day failure interval) is excluded until due.
