[architecture] Agent self-reflection fails to catch its own hallucinations or logical errors

Use an independent, isolated Evaluator agent with a distinct, strict rubric to verify the Worker agent's output, rather than asking the Worker to check its own work.

Journey Context:
It is tempting to append 'Double check your work' to an agent's prompt to save compute. However, LLMs suffer from confirmation bias and often rationalize their previous outputs. By separating the Worker and Evaluator into different agents \(or at least distinct turns with isolated context\), the Evaluator isn't anchored to the Worker's reasoning. The Evaluator should output a structured pass/fail with reasoning, which acts as the contract for the next step.
