I have built a non-functional Golemn farm. As you can see, I have a spawning platform, 10 doors on each side, and I have over 10 villagers behind each of the four chambers. The entire quarry is in direct contact with the sky and there are no blocks that block out the sky - so the doors should register as village doors.

I have attached screenshots of my farm. The glass chamber is just an area in which I jump into and sit to watch the collection tube beneath me.

The rim perimeter around the source blocks of the spawning platform are half slabs on top of solid blocks.
