Thanks again for the feedback all!
I found an extra longer spoke in my garage and threw it on there.
The rim has pretty intense brake wear, but I remined myself I brake almost entirely on the FRONT rim so not worried about it getting much worse.
Trued it up (or pretty close, for commuting purposes only LOL) … just need to reinstall rim tape, tube, and tire!
Bonus - while I had my commuter on the stand (rare, very reliable low maintenance single-speed) I threw my little brother's Brooks saddle on there so we'll see how my butt enjoys that!
