        $relStore = $this->orm->queueStore($related);

The method queueStore() does not exist on Cycle\ORM\Select\SourceProviderInterface. Since it exists in all sub-types, consider adding an abstract or default implementation to Cycle\ORM\Select\SourceProviderInterface.

        $relNode = $this->getNode($related);
        $this->assertValid($relNode);

It seems like $relNode can also be of type null; however, parameter $relNode of Cycle\ORM\Relation\AbstractRelation::assertValid() does only seem to accept Cycle\ORM\Heap\Node, maybe add an additional type check?

        $this->forwardContext($relNode, $this->outerKey, $parentStore, $parentNode, $this->innerKey);

        return $relStore;
    }
