#C.30.TFS-REL:4.1 - Use trigger

Preface node heading:c-30-tfs-rel-4-1-use-trigger:55591

#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

Use this pattern only when a ArchitectureOf@Context claim being made, selected architecture-relevant structure, architecture structural view, functional-structure view, transformation-flow-structure claim, or conditional ArchitectureDescription@Context use depends on one or more E.18 objects:

• TransformationFlowStructureRef;
• PathId or PathSliceId;
• CrossingBundleRef;
• U.Transfer flow valuation;
• edition, plane, or context pin;
• no-hidden-scalarization or set-return discipline;
• correspondence between functional structure and transformation-flow structure;
• generated or extracted relation graph used as architecture-to-transformation-flow source material.

If the sentence only says that work occurred, use A.15 or the governing work pattern. If the sentence only says that a selected transformation-flow structure exists, use E.18. If the sentence uses a graph-shaped expression as mathematical description, use E.18.2. If it relies on a mathematical lens, use C.29.
