A picture is worth 1,000 words - finished last night.
Previously all flooring had stopped at the shelves on the left hand side. That is 3 layers to put down; the Air Gap system, OSB and then linoleum.
Not done with the short section that leads to the heater room, but all in good time.
PS - can't recommend Magic Sliders enough. Wish I had found them at the beginning of this while I was moving the washer and dryer all around. I even found some that worked for the legs of the metal shelves on the left. Found them at my local hardware store.
