#A.19.CN:Close

Preface node heading:a-19-cn-close:32089

#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

A.19.CN makes comparability operational: a one-page CN-Spec, a registry for edition, status, supersession, and deprecation records, explicit relations and receiving-use claims for cross-local reuse, and a checklist plus harness for audit. It remains tool-agnostic and keeps every reading tied to its characteristic and scale editions, bearer, comparison basis, scope/window, evidence, and intended use.
