The commit hashes on both of those mirrors match the official ones at least until March 2024 (v1.1.1217). I can't vouch for the more recent commits that extend through today (v1.1.1403), but the two mirrors do at least match each other.

Warning: A zip file in the ryujinx_202410 subdir of https://archive.org/download/ claims to have the full git history, but the hashes do not match the original source repo. It's possible that the mismatch is an artifact of some accident, rather than malice, but I would avoid it just in case.

Regarding the second link, I've personally git pulled Ryujinx about once a week (except this week lol) ever since Yuzu was taken down. I don't know enough about git to know if commits earlier in the history can be manipulated whilst keeping later commit hashes identical, but I can confirm that the commits from last Tuesday match up with my local copy in terms of hash, author and message
