Suppose that the planner has determined that plans in a particular group has some property, such as a particular sort order, allowing us to eliminate a LogicalSortExpression. It is critical that no future rule application produces a planner expression in that group that does not have a sort order compatible with the desired one.

The standard Cascades answer to this is property enforcement, where we annotate groups with a set of properties that their members must satisfy.
