build_exe.py now runs compile -> link (+ .map) -> patch. scripts/exe/postprocess.py applies scripts/exe/patches/NNNN_*.py in order, each located by symbol, verified against exact bytes, dropping base relocations it overwrites; --no-postprocess skips it. 0001: CSession::LoadExternalSettings jumps over switch (g_serviceType) to case 0, as the original does at 0x00DFD08F (e9 10 00 00 00).

## How to Build
|
|
|
|
```sh
|
|
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.
