Consistency

The idea
A set of statements is consistent when at least one row makes them all true together.
In practice
"The defendant was in Springfield" and "the crime occurred in Peoria" — consistent or not depends on a timeline row existing.
Where people slip
Consistency is cheap — one shared row does it. Truth is a different, harder question.
