MEASUREMENT — Make a number interpretable before relying on it

• Situation: A reading, score, rating, sensor value, or dashboard number is being compared or used in a decision.
• Question: What exact subject and characteristic were measured, on what scale and unit, by what method, and under what calibration and time stance?
• First useful result or blocker: An interpretable attributed value with uncertainty and a use boundary, or the missing subject, scale, method, calibration, evidence, or validity window.
• Start with: C.16.
• Stop or return: Stop when the value supports the present comparison. Return when the subject, method, calibration, time stance, uncertainty, or use changes.
