    // When they do, we still want the UI to reflect the ruleset state
    // accurately and "Edit" + "Save" shouldn't destroy data unless the
    // user explicitly modifies the ruleset.

    // In this mode, when we run into rules which are structured correctly but
    // which have types we don't know about, we replace them with "Unknown
    // Rules". If we know about the type of a rule but the value doesn't
    // validate, we replace it with "Invalid Rules". These two rule types don't
    // take any actions when a card is dropped into the column, but they show
    // the user what's wrong with the ruleset and can be saved without causing
    // any collateral damage.
