Libreoffice 7.6 code checkout from https://dev-www.libreoffice.org/bundles

[Alex]

Hi everyone
Does the 07-May-2023 release of 7 codepacks from  
https://dev-www.libreoffice.org/ bundles
contain the code to check out and compile lo7.6 alpha 1 build, offline and 
self-sufficient?
Debian 32 and 64bit
 
How do I ‘checkout’ the exact alpha release from what i assume is a more 
generic codebase in the above bundles.
 
Many Thanks
