#A.19.CN:Close

Preface node heading:a-19-cn-close:25686

#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 gives A.19 some teeth: a CN‑Spec you can put on one page, a Registry that stops sprawl, Bridges that carry explicit loss, and a checklist + harness that make comparability auditable. It obeys the mandatory pattern structure of Part E (style, checklists, DRR, guard‑rails) while remaining tool‑agnostic and context‑local.
