Following up the above. I don't know when the tape went wrong. It was not always. There's clearly sealant inside the rim now. When sealant leaked into the rim it sealed up the nipples and threads, and they were sometimes holding pressure. There are boogers at nearly every spoke hole. The nipples don't look great, I don't know if they would turn if they needed to. There's gooey webs of rubber on the beads of the tire. To add insult to injury, when I threw out the tape and drained the tire, I dropped the nut for the valve down into the dumpster, where I will not be chasing it. Nevertheless I will probably just throw it back together, maybe with Gorilla tape this time. It deserves outright replacement with something better, but none of it is actually broken, and I don't want to afford it right now.

I got out the Baconator to ride, and it was fine.
