Evaluation is the operating system
The learning loop belongs in the product design, not at the end of it.Define success measures and failure modes alongside the workflow. Capture disagreement, low-confidence cases, overrides, and downstream outcomes. Those signals should shape prompts, retrieval, policy, and product behavior through controlled change—not silent model drift.
Apply the idea
Use this principle as a review question: where is the relevant evidence visible, what remains governed by explicit rules, and who has the authority to challenge or stop the system?
