CakePHP 3.x case statement on order - cakephp

Question

I am trying to use a CASE statement on the order of a MySQL statement in CakePHP 3.x app. The simple select is as follows:
$articles = $this->Articles->find()
->where($conditions)
->order(function ($exp, $q) {
return $exp->addCase(
[
$q->newExpr()->gt('Articles.modified', (new Time())->subDays(365)) // article has been updated in the last x days
],
['priority'], # values matching conditions
['string'] # type of each value
);
})
->limit(15)
->all();
The following SQL is generated:
SELECT `Articles`.`id` AS `Articles__id`, ....
FROM `articles` `Articles`
WHERE (`publish` < :c0 AND `Articles`.`publish` > :c1)
ORDER BY CASE WHEN `Articles`.`modified` > :c2 THEN :param3 END LIMIT 15
The case statement is not correct because it is missing the DESC order which should come after the 'END' - see this fiddle:

I'm not sure if this is a limitation with how CakePHP handles CASE?
Further I require a second order after the case statement to order by 'publish' desc.

Expressions passed to Query::order() must generate everything required by the ORDER BY clause, including the direction keyword.
If the expression that you're using doesn't support that, then you can use Query::oderAsc() or Query::oderDesc(), which will append the respective direction keyword accordingly.
$query = $this->Articles->find();
$query
->where($conditions)
->orderDesc(
$query->newExpr()->addCase(/* ... */)
)
// ...
