[synthesis] Agent persists in wrong answer across multiple reasoning steps, citing retrieved documents that confirm the wrong premise

Implement divergence detection: calculate semantic drift between original query intent and current reasoning path; if retrieved documents show high similarity to each other but low relevance to original query \(high intra-cluster similarity, low query-cluster similarity\), force adversarial retrieval with negated query terms.

Journey Context:
Standard RAG retrieves top-k similar docs based on current step's query. If step 1 makes a wrong assumption, step 2 retrieves docs validating that assumption \(echo chamber\). The error isn't in retrieval accuracy—it's in the feedback loop between reasoning and retrieval lacking adversarial validation. Single-source articles discuss RAG or reasoning failures, but the synthesis of 'confirmation bias in retrieval loops' only appears when holding both failure modes simultaneously.
