Help Trying to figure out Kleaf/Bazel kernel build system

Hi everyone, hope some of you could help me with my problem.

The thing is I don't even have an idea how do I compile Bazel kernels and which logic is the most suitable one for me to feel at least a little bit comfy when trying to figure out kernel build problems, why do I need common kernel tree, why do I need msm kernel tree (btw I'm using OnePlus and their kernel manifest) and the thing isn't just my misunderstanding, it's about searching for at least a little source that tells how and where to begin, I did already like 3 times but all those were unsuccessful, by the way somewhy when I boot the compiled image I boot up in android thrice longer and get no wifi problems.

If anyone here an experienced GKI kernel building master that can gimme over their knowledge just a little bit, please, show me yourself! I would be screaming from happiness and appreciation.

Common tree is used to compare symbols against an agnostic tree to verify abi integrity with vendor additions. If you are building with lineage a bunch of additional changes are needed and can be found in the respective qcom common kernel (android_kernel_qcom_sm8X50, *-devicetrees, *-modules). It's not a simple task to take on, additional manual changes might be needed to get images and/or modules to build/work properly. I'm not a master, just someone who is observing the build system that I may have to use in the future.
