Can Claude tell which SMB library was vibe-coded?

Two Rust SMB client libraries. One built by a human over a year, the other vibe-coded in a day by someone who didn't know much Rust. Claude Code tries to figure out which is which, just by reading the code.

David: I have /tmp/smb2/ and /tmp/smb-rs/, two libs for the same thing. One of them is written with hard human work over 1 year, the other one is vibe coded in a day by someone who didn't even know much Rust. Without looking at .git and the file dates, and not using any subagents to do research work, WDYT, which one is which, based on code quality and lib usability?

Read like 1-1 files of each lib at a time, then speak out your thoughts-in-progress loud so I understand where you are in the process of figuring it out :)

Project	Commits	Added	Deleted	Net	Summary
smb2	40	+38,628	-2,236	+36,392	Built an entire SMB2/3 client library from scratch in one day. Wire format for all 19 commands, NTLM auth, signing (HMAC-SHA256/CMAC/GMAC), encryption, compound requests, pipelined I/O, streaming downloads, file watching, CI, benchmarks. Beats native macOS SMB on all operations.
