Are you sure the rail that you've coloured green is the ground rail?
Yeah I'm sure of that. I used a logic gate that I could clearly see to figure which rail was power and which ground and then just followed them and colored over them to map them out.

I'm not sure the fat poly on the right is actually a transistor: I don't see edges where the active crosses the poly.
I too was questioning whether there actually is a transistor. Perhaps it was supposed to be something, but then it was disconnected? The pin should still work without it, even though it doesn't seem to have any protection (although I'm not sure if it even needs any).
