I don't think it's vibe coded garbage. Sure, the 3000-line print.ts is terrible, but there's some good patterns in there that were definitely prompted in by some experienced engineers -- the feature flag setup, the `..I_VERIFIED_THIS_IS_NOT_PATH_OR_CODE` funny type hints, the overall structure. Just the usual signs this started as a PoC but quickly evolved into something much bigger. The codebase is a really interesting read.
