Report #51950

[synthesis] Agent retrieves and re-ingests its own previously generated flawed outputs, reinforcing errors

Tag all agent-generated documents with a 'provenance' metadata field. Filter retrieval results to exclude or heavily down-weight documents generated by the agent itself in previous runs.

Journey Context:
Agents that write to a knowledge base and read from it can create an echo chamber. If the agent makes a subtle error, writes it to the DB, and later queries the DB, it retrieves its own error as 'fact'. The retrieval score is high \(exact semantic match\), so the agent trusts it. The system looks healthy \(retrieval working, no errors\), but factual accuracy degrades exponentially. Monitoring retrieval relevance scores masks this; you must monitor retrieval provenance.
