I’m deep in the middle of upgrading my intro to sign relations and I am determined to stick to it this time but there will be a phase when it’s critical to bring category theory to bear on the development.  I had a nagging sense we had been discussing category theory in a related connection just recently but when I went back through my records it turned out this was way back in late 2018.  (I was a bit occupied with moving our household and lost track of many loose threads.)  At any rate, I’ll just post a few links here as reminders of topics to pick up later.
