030     * the final model of the project being assembled. There is no
031     * overriding going on amongst the models being used in this test:
032     * each model in the lineage is providing a value that is not present
033     * anywhere else in the lineage. We are just making sure that values
034     * down in the lineage are bubbling up where they should.
