the initial commit [0] is from 3 days ago, and contains ~45k lines of Rust "Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>"

in the last three days, if the readme is to be believed, it's grown to 92K lines of Rust.

so it seems like this is somewhere between 99% and 100% vibe-coded?

it might be worth mentioning that in the readme, possibly instead of the "not a proof-of-concept" claim.

the architecture diagram in the readme seems like it describes ZFS, including identical terminology (ARC, RAID-Z, etc). so that's either inaccurate, or it reveals that the prompt given to Claude was basically "write a clone of ZFS but in Rust".
