carrying balls on caps ?

Awhile ago there was a discussion on whether it was legal or not to carry more than two balls on a cap. I can’t seem to find it. Does anyone know what the decision was ?

Only two balls are allowed
Refer to :

but what if you have two balls in your robot and a third on a cap. Would that be illegal or because it is touching the cap, and not your robot would it be fine

I found the thread where this was discussed previously and it seems sg7 would make it illegal.
