+The last stage is why this paste is four lines rather than ten, and it is not
+tidying. The sweep also returns the six per-platform `build` entries, whose
+verdict is the `build` row of the table above and reaches them through
+`docs/decisions/0012-the-supported-platforms.md`. Those six are the one place a
+literal is deliberately absent here, so pasting the unfiltered output would
+write the six strings into this document and end the absence in the act of
+describing it. The stage drops them by the row name the table already carries

+That the paste needs the stage at all is the shape to take from this section: a
+sweep for names this document does not carry cannot have its full output pasted
+into this document, because the paste is what makes the answer wrong. What is
+left after the stage is the gap, and it is four names.
+
+A fifth name is one too and this sweep cannot show it at all. `release`
+matches as a word inside the reason on the SBOM row rather than as a
 verdict of its own, which is the false pass a fixed-string comparison gives and
 the reason the tree holds the list that decides this in
 `internal/contexts/contexts.go` instead.
