ReviewLog keeps every rating of a card: the card, the rating (FSRS's 1 again to 4 easy), when (UTC) and how long answering took, as decided. It is never changed; each device derives a card's schedule by replaying its reviews, so reviews from different devices never conflict. No device id: the sync engine knows each row's device. The migration (by CLI) only adds: the table, an index on spaceId for space deletion, one for a card's reviews in time order, and the foreign keys (from the space with ON DELETE CASCADE; from the card with ON DELETE CASCADE, DEFERRABLE INITIALLY DEFERRED).
