Reported this out after a tip from the incomparable @MikeWiseguy with further tips (and photos!) from @tlsandys. And got to interview Mara C., who plays accordion in puppet shows AND is a history whiz who reviewed 100,000 property records in search of systemic racism.
I was like, "Mara, there's no way there's a racist covenant at my house, I live in D.C." And she was like: "No, there probably is." And then she looked it up and showed it to me and I was like: "That's really bad!"
For DC people who want to search their property records for horrible things, go here. You need an account, but it's free. You probably won't like what you find! https://countyfusion4.kofiletech.us/countyweb/login.do?countyname=WashingtonDC
