# RED4ext logging shim

`EdgeWeightGPS` is a minimal RED4ext plugin used to verify a native logging foothold without changing gameplay data.

It writes `EdgeWeightGPS.log` beside the installed DLL:

```text
Cyberpunk 2077/red4ext/plugins/EdgeWeightGPS/EdgeWeightGPS.log
```

Current behavior:

- Logs plugin load/unload.
- Logs the RED4ext plugin handle and SDK pointer value passed to `Main`.
- Does not call game RTTI or register script functions.

Planned next step:

- Build a richer RTTI/hooking variant with an MSVC-compatible Windows toolchain or a narrower hand-written SDK surface. The upstream RED4ext SDK headers build under MinGW for loader-only use, but the full SDK/static library currently pulls in generated native/GPU structures with MSVC layout assumptions.

Build and install from the Fedora toolbox:

```bash
toolbox run -c 2077 ./tools/install_red4ext_shim.sh
```

This shim is read-only. It does not enable any of the archived traffic data patches.
