    What this page is

    This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

    Methodology

    Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

    Content

    • 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 honest 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.
