Summary

Adds FAISS vector backend using LlamaIndex adapter.

Implementation

FAISSBackend - Full KnowledgeBackend implementation
In-memory with persistence - Manual save/load to Frappe private files
LlamaIndex integration - Uses llama-index-vector-stores-faiss

Files

huf/ai/knowledge/backends/faiss_backend.py
huf/ai/knowledge/tests/test_faiss_backend.py

Dependencies

Optional: llama-index-vector-stores-faiss, faiss-cpu

Notes

In-memory only (fast but no persistence without save)
No metadata filtering support (FAISS limitation)
Best for research and development

Related
