RAG comparison

Agent Knowledge does not replace RAG. It gives RAG systems a portable source-of-truth package.

Layer	Agent Knowledge role	RAG role
Sources	Stores raw evidence	Can ingest and chunk
Wiki	Maintained synthesis	Optional upstream structure
Compiled views	Runtime-friendly context	High quality retrieval targets
Indexes	Rebuildable artifacts	Vector, full-text, graph search
Resolver	Selects context	Retriever / router / reranker

Key rule

A vector store MUST NOT be the knowledge asset. It is an acceleration layer derived from the knowledge asset.

If deleting the vector index deletes the only copy of the facts, the system is incorrectly designed.
