We added vector integrity contract work to make retrieval failures explicit. Bad vector state should fail as a system issue, not silently degrade into weak answers.
This improves failure transparency. It does not guarantee answer accuracy by itself, but it reduces one class of hidden retrieval errors.
We clarified the boundary between conversation memory, retrieved evidence, and answer synthesis in the Agentic RAG runtime.
Ingestion guardrails were added to make document handling and chunk quality more explicit before retrieval uses the content.
A feedback store was added so retrieval and answer behavior can be improved from recorded outcomes instead of anecdotes.
