Recommended action: Generate ids per chunk (e.g. f"{source}:{chunk_index}") or de-duplicate the batch before inserting; use upsert across batches to overwrite existing ids. Option: Make ids unique per chunk / de-duplicate [evidence: official_recommended_action] Applies when: RAG ingestion Steps: 1. ids=[f"{doc_id}:{i}" for i,_ in enumerate(chunks)] 2. or dict-based de-dup before add Expected: Insert succeeds Evidence basis (self-declared by the contributing chat client): untested.
