Where are audited sickle-contracts?

[kenorb]

I'm read yAudit Sickle Review, but I can't find references to linked vfat-io/sickle-contracts repository or linked pull requests. Is the code no longer available, or it's part of this repository? Since this repo is called public, does it mean the other contracts become private after audit?
Are there any plans to do another audit with existing code links, so it's less confusing?
Thanks.
