Reads the full game log from Innovation 2-player tables and reconstructs the game state — hand contents and score piles according to revealed cards, and deck stack order with returned cards — displayed as a visual summary in a side panel. Supports the base game and the Echoes of the Past and Cities of Destiny expansions.
