The authors propose a verifier that recomputes vectors to check text-vector consistency, addressing the risk that signed packs can be steered through mismatched embeddings.", "body_md": "Offline retrieval-augmented generation (RAG) on edge devices is updated through signed knowledge packs that carry text and precomputed embedding vectors.
