I just skimmed through the porting guide and based on the number of unsafe blocks, this looks like a fairly straight-forward mechanical translation.

If that is the case, why didn't they just "vibe-code" a Zig->Rust translator and a small Rust/TS/JS/whatever script to orchestrate things. You don't even need pretty printing support because rustfmt exists.

You'll save on a bunch of tokens, probably a lot of time/enegy, the process becomes auditable and (hopefully) deterministic, and if there's a mass bug in the translation, you only have to fix it in one spot.
