This is our debate.

The side of the Frame Perimeter.

Here is how to settle the debate: Take a string, stretch it around your frame. That string is your Frame Perimeter. Any point where that string forms a corner must have 8" of bumper on either side, plus a fill-in piece to fill the corner. If the string forms a curve, the entire curve gets a bumper.

I've attached a full-robot sample image--one side of the opening is legal, one is not. Your design is currently on the "not" side of that.
