[synthesis] Agent's previous incorrect outputs contaminate future reasoning through recursive context inclusion

Maintain 'ground truth' buffer separate from generated content—validate new outputs against source documents, not previous agent summaries; implement 'source-grounding' checks that require citations to original context

Journey Context:
Including previous agent responses in context creates an 'echo chamber' where hallucinations become self-reinforcing. The failure is subtle because the agent appears to be 'reasoning' but is actually iterating on its own confabulations. Distinguishing authoritative sources from generated content requires explicit tagging in the prompt context \('SOURCE:' vs 'GENERATED:'\). The fix requires not just retrieval but 'source-grounding' constraints that force the model to cite specific chunks of the original context, making hallucinations detectable via citation verification.
