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