RAG Permissions in Python with OpenFGA: Filter Documents Before Retrieval

About this lesson

RAG security fails when retrieval happens before authorization — prefilter documents with OpenFGA to keep forbidden text out of your model. Implement a permission-aware RAG flow in Python to check document access, prevent data leakage, and reduce unnecessary scoring. Demo covers OpenFGA (authorization model, tuples, list-objects) and a small Python search wrapper you can scale with an ANN index.
