I probably assembled the chain contrary to the proper procedure. These 9 and up chains are finicky. It wasn't a master link failure.
The back plate of the pulley cage is bent, bu I think I can get the derailleur back together. Same with the chain. I will buy a new cassette, though. It's OK; I'm not too discouraged. The bike is almost done, and it's worth it.
