What make you think it is vibe coded? There is no mention of genAI being used, and the methodology looks more consistent with hand-written code he actually understands.

You don't have to fully vibe code it. Most of this stuff doesn't take massive brains, it is just super tedious - especially the reverse engineering. I've never really had the patience for that (except one USB devices that I did reverse engineer when I was younger). AI really helps with the tedium.

If it is coded in safe Rust, why not ?
