Much of this page is wrong because much of the PAF is written in C++ but it works as a "function".
A good resource (to merge here) can be found at ScePaf-headers by Graphene.
Module
ScePaf is a C++ runtime.
This module has many virtual tables that point to exported functions. It would be great to start from marking which function belongs to which vtable. This way we can restore initial class structure.

Libraries
TOOL version of libpaf module is different from CEX and DEX ones as it has an additional library: #ScePafAutoTestTty. Some TOOL system apps import this library and crash on CEX/DEX systems because of that missing library.
