E.g. define a win for 3 in a row.....
To freeze time to define a win, we want a completion that maps all states to that frozen time state. Win = spacelike singularity.
What are the threat coordinates here?
There are no causal connections, because no writing in any cell can ever affect writing in the same cell, except by excluding it....

All separations are spacelike; i.e. there are only a finite number of places to have something happen
