[synthesis] Agent experiences recursive context poisoning where incorrect conclusions from early steps are written to persistent memory and subsequently retrieved as ground truth in later steps, creating self-reinforcing error cascades

Implement epistemic fencing - tag all information written to persistent stores with confidence metadata and source step ID; when retrieving context for new steps, apply a recency bias filter that requires recent high-confidence external validation before accepting old stored conclusions as premises; if retrieved data originated from the agent's own previous outputs without external verification, flag as circulus in probando and require independent verification.

Journey Context:
This addresses the failure where agents use RAG or state stores to learn from previous steps, but those previous steps contained hallucinations or wrong assumptions. The synthesis combines: \(1\) observations that retrieval-augmented generation amplifies early errors when the retrieval corpus is contaminated by previous agent outputs, \(2\) the realization that agent memory systems rarely track who wrote this \(external vs self-generated\), and \(3\) the pattern that confidence scores are rarely propagated through storage. Common mistake: treating RAG as external knowledge when it's actually agent-generated content. Alternative: wiping memory each session \(loses valid learning\). Why right: epistemic fencing prevents circular reasoning by tracking provenance and requiring external grounding for recycled facts.
