A miracle! I like it. Metal components from numerous applications are manipulated precisely with heat and pressure everywhere and everyday. This is pretty basic stuff and there’s no real issues other than straight or not straight. It’s good the builder recognized something that needed someone and the tools to know what to do. Radial impact like a backfire is the most likely suspect for bending and a smack in the opposite direction is the cure. If I was spending money on a crank it would be a drilled one from a 235. Good luck.
