Report #28686

[synthesis] Agent quality drops silently because RAG retrieval returns outdated or conflicting documents

Track the average age or version hash of retrieved documents. Set alerts when the distribution of retrieved document versions diverges significantly from the expected latest version.

Journey Context:
If the codebase or knowledge base updates but the vector store isn't perfectly synced, the agent retrieves old API patterns. It writes code that 'works' against the old API but fails in the new environment. It doesn't throw an error during generation. Monitoring document metadata is the only way to catch this.
