E.14:2.1 - Problem

A reader may need to decide, design, review, or coordinate with FPF terms before they are ready to inspect mapping tables, constructive traces, evidence records, or proof arguments. If the working text exposes all of that machinery first, the model becomes unusable; if it hides the machinery completely, the model becomes arbitrary. E.14 keeps one human-facing Working-Model visible while making the assurance shoulders recoverable beneath it.
