Report #49263

[frontier] How do agents avoid hallucinating when retrieved context is contradictory or unreliable?

Inject epistemic markers: augment retrieved chunks with metadata tags indicating source recency, confidence scores from retrieval models, contradiction flags from cross-reference checks, and provenance chains, then train/few-shot agents to perform belief revision using these markers as uncertainty signals.

Journey Context:
Naive RAG treats all retrieved text as ground truth, causing agents to synthesize hallucinations when sources conflict or are stale. Post-retrieval reranking helps but doesn't propagate uncertainty through reasoning. Epistemic markers make uncertainty explicit in the context window, allowing downstream agents to apply Bayesian updating or conflict resolution heuristics. The alternative of hard filtering retrieved content is too conservative; markers allow graceful degradation. This emerges from production failures in legal/medical agents where source authority varies drastically.
