[architecture] Single-agent output errors undetected due to weak validation sharing generator failure modes

Implement adversarial or orthogonal verification agents that independently validate outputs using different methodologies, only proceeding on consensus or defined confidence overlap

Journey Context:
Simple validation \(JSON schema, regex\) catches syntax errors but not semantic errors \(wrong calculation, hallucinated fact\). Using the same LLM to 'check its own work' often fails because it repeats the same biases and hallucinations. The robust pattern is using a distinct verification agent with different instructions, tools, or even a different model architecture \(e.g., generator uses GPT-4, validator uses Claude, or rule-based system\). For critical steps, use 'red team' verification where the second agent actively tries to find flaws or prove the output wrong. The architecture must define consensus rules: unanimous, majority, or weighted by confidence scores. This doubles \(or triples\) API costs and latency, but for high-stakes decisions \(medical diagnosis, legal contracts, financial calculations\), this is the only reliable pattern. The alternative is accepting uncaught errors that compound downstream.
