Ghost Notation
Conduct a courier and its ghost echo through the score. Solid P starts bottom-left facing up; hollow G starts top-right facing down. Forward moves one cell, turns change facing, and Rest stays still. The ghost performs your command from TWO beats earlier; its echo moves first each beat. Reach the opposite corners with BOTH actors within fourteen beats. Dark walls stop the performance. The two center-edge gates stay closed until the ghost steps on the gold plate near the bottom-right; the plate latches both gates open permanently. Rest before a locked gate so the delayed echo can catch up. Actors may pass through each other.
