## Invalidation of a fact that a later fact ends

When a new fact states that an earlier fact ended, Zep now invalidates the earlier fact. The `invalid_at` value of the earlier fact is the end date of the new fact. When the new fact has no date, Zep uses the reference time of its episode. Before, the earlier fact stayed valid unless the new fact had a later start date.
