Show HN: I made Permission-aware RAG – fine-grained authz for vector search
3. Retrieve only authorized chunks.
Same question, different users, correctly different answers.
FGA is new in this release, and I'd especially love feedback on the relationship model, schema ergonomics, and scaling strategies for large allow-lists.
I'm also curious how others are solving permission-aware RAG today: OpenFGA, OPA, homegrown filters, something else?

Happy to answer questions about the architecture, Zanzibar tradeoffs, MCP integration, or why we put this inside the auth server rather than a separate service.
