    # phpstan learns a constant exists only by executing the define(). tests/settings.php declares them and
    # does nothing else, so running it keeps the analysis independent of the database.

        # both are written by a run rather than committed, so they may not be there at all - "(?)" is what

        # types on its own methods - a test method returns nothing and says so by being a test. Everything
        # else phpstan finds there is still reported.
