+//
+// The stock generator stamps an entry with the newest commit that added its
+// changeset file. A revert of a version commit re-adds every changeset that cut
+// consumed, so after a re-cut every entry names the revert: 260 of the 265
+// entries in 18.1.0's CHANGELOGs open `- 3937697:`, the commit of #25605. Here
+// an add that restores the bytes an earlier commit deleted is passed over, and
+// the entry names the commit that first added the changeset.
+//
+// Nothing else moves: the line format is the stock generator's, and whatever
+// the attribution cannot decide keeps the stock commit with a `::warning::`.
+// The pins live in `node scripts/release-pending-publish.mjs --self-test`,
+// which lint.yml runs: an add -> version -> revert -> re-cut fixture through
+// these two functions.
