[synthesis] Agent retrieves only documents supporting its current hypothesis, ignoring contradictory evidence in the same knowledge base

Enforce 'Belief Delta' retrieval: require the agent to formulate its current hypothesis explicitly first, then retrieve documents that would falsify that hypothesis \(adversarial retrieval\) before confirmation

Journey Context:
Standard RAG retrieves based on semantic similarity to the query, but if the agent's query is already biased \('evidence that X is true'\), it retrieves confirming evidence. This creates an echo chamber where contradictions are filtered out by the embedding similarity function itself. The 'self-consistency' approach helps but doesn't break the filter bubble. Active adversarial retrieval \(explicitly querying for counter-evidence\) breaks the loop. The agent must first commit to its belief, then search for disproof. Tradeoff: higher latency, more tokens, but prevents cascading wrong decisions based on filtered retrieval.
