How to Build

python scripts/exe/gen_ide.py     # generate build/Ragexe.sln
python scripts/exe/build_exe.py    # or build the .sln -> build/exe/Ragexe.exe

build_exe.py runs three stages in order: compile, link (Ragexe.exe, .pdb, .map), then patch. The patch stage (scripts/exe/postprocess.py) re-applies byte edits that the shipped executable received after it was compiled and that no C++ source can express (e.g. a jmp written over a switch head). The source keeps the code as it was compiled; each edit is one documented module in scripts/exe/patches/NNNN_name.py, applied in NNNN order, located by symbol and checked against the exact expected bytes. A patch that does not fit fails the build. --no-postprocess gives the exe exactly as the source compiles. Clank checks never see these patches.
