Flashcards

Spaced-repetition drill (SM-2). Cards are mined from the Reference facts across the vault — the exact values, IDs, defaults and other volatile bits worth memorising rather than merely understanding. Any volatile fact that may drift is flagged so you re-verify it against the source.

Read the prompt, guess the masked value (○○○○), then reveal the answer and grade yourself: Again resets the card, Hard/Good/Easy push it further out. Grades feed the scheduler, so the deck resurfaces cards right before you'd forget them. Progress is stored on this device. Space reveals; 1–4 grade.
