#A.19.SOURCE-SET-SPACE-SUBSTRATE:5.3 - Boundary anti-case

Preface node heading:a-19-source-set-space-substrate-5-3-boundary-anti-case:24714

#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

Tell. One note says only that "the shortlist front is the published result for the current selector result" and names no source-to-outcome relation, no search-side space, no outcome-side space, and no posture.

Show. This is not a substrate declaration. It is publication metadata over one already-selected set.

Cash-out. Apply G.5 or G.10 to that note. Do not pad it with pseudo-substrate words just to make it look deeper than it is.
