The local wrapper source is `tools/fortune_ai/worker.cpp` in this game repository.
This is a third-party local language model, not ChatGPT or a cloud service.

No runtime model downloads or external servers are used. The model file is part
of the complete release archive, not Git history. After cloning or copying source,
run the separate root `download_fortune_model.bat` to prepare the pinned weights.
This optional setup downloads and verifies the file before offline gameplay.
