        A SystemVersion defines the specific settings for a System Under Test.


        System versions contain parameter values that determine system behavior
        during evaluation.

        They are immutable snapshots - once created, they never change.


        When running evaluations, you reference a specific systemVersionId to
        establish which system version to test.
