Rendezvous at 140,000m
Docking two spacecraft is notoriously hard, in real life as well as in Kerbal Space Program. Making use of this nifty guide I was able to get close, and after quick saving/loading through a few bad misses, managed to dock the final part of Clowder Station.
I also took the opportunity to swap out Jebediah for Rayvis Kerman. Jeb's a little too precious to risk losing in a random space junk strike.
And then the launch vehicle carefully deorbited, taking its main fuel tank with it, leaving Rayvis in charge of a slightly skew-whiff space station.
