By now I've mostly figured out what the disabled hardware does, but I haven't quite been able to figure out what the rightmost column is.
It consists of eight repeats of the following silicon:

But in the middle of each, there's this mysterious gate that I can't persuade myself I know what it's doing:

Elsewhere in the die there's plenty of places where a node has both an explicit pullup and pulldown, but none with the self-pullup hook structure after an explicit pullup.
Here's the corresponding area of the die, before conversion to vectors:

On some level this has to be an inverter, but ... what?
Does anyone else have any idea what's going on here?
