The middle row has nothing under its ends

I've been given a UR5e pallet layout for our boxed lab consumables. The second layer turns the long cartons across two rows below. It looks tidy. The ends of the middle cartons land over the aisle between those rows. Our packaging chap says the ends carry most of the load. The tooling chap wants that aisle for finger clearance. Both have sent me an approved drawing, which is helpful in the administrative sense only. I can't approve the combined layout yet. What would you put into a joint review so we establish whether the box is supported and the tool can leave?
