Log a game
Check the model against the game you just played.
Four commanders, the winner, the turn it ended, how it ended. Attach lists if you have them — those rows score sharper.
Logging a past game?
Games logged at the table need none of this — the current engine version is stamped automatically. Backfills stamp the version their prediction was made under.
Logged games also feed the public calibration record. We publish misses.
