Use throughout the EXECUTION of any analysis — while running, debugging, modeling, or cleaning data — to decide which decisions you may make on your own and which you must STOP and bring to the user first. Forces a human-in-the-loop checkpoint before any consequential analytical choice — changing the research design, estimand, or identification strategy; deviating from the framed question or pre-analysis plan; dropping/filtering/winsorizing data or changing the sample; choosing between materially different specifications; redefining a metric; or changing any number the user has already seen. Use this whenever you catch yourself about to "just fix it", "upgrade the design"…
