Has anyone investigated that 2023 valve dev leak?

[Valina35]

Back in 2023 valve repository leaked but i havent seen anyone here look for hl2 beta assets in it that much
Doing it myself and with help of ai and using these lists (Which i dont know if its accurate):
https://hl2-beta.ru/index.php?action=articles;sa=view;article=51
https://hl2-beta.ru/index.php?action=articles;sa=view;article=50
There seems to be heavy amount of hl2 beta content but no one seems to have ported them to leak
here are some things i found with help of ai https://imgur.com/a/bXajhmi along with some of them extracted from the 2023 leak
im not sure how accurate it is but havent seen many talk about it
