#A.12:4. Solution

Preface node heading:a-12-4-solution:19717

#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

The solution is a two-part architectural mandate: (1) all transformations must be modeled with an external agent, and (2) apparent self-transformation must be modeled using the Reflexive Split.
