Field notes
The workspace presents a baseline policy and a candidate prompt, including a shorter-instructions version and an explicit-policy-checklist version. Its controls let the evaluator choose one or three trials, while a policy review step asks for approval before the local test. The page also offers a scripted-fixtures option with no model calls; the extracted view does not show a completed comparison or its results.
