+### dist export no longer cuts the dist export record out of the shipped tools/CONTRACT.md
+
+`dist export` removes every `dist:strip-start`/`dist:strip-end` marker span from the files it
+ships, and the `dist export` record's own notes quoted that marker pair literally - so the export
+cut a piece out of the middle of the generated command region, and the fresh instance's own
+`docs verify` then reported that region stale. CI's fresh-instance replay caught it on the first
+push. The old table row carried the same quote and was mangled the same way; nothing compared the
+shipped copy against its source until the region became generated. The record now names the
+markers without spelling out the pair, and a new test pins that the export plan ships
+`tools/CONTRACT.md` byte-identical to the working tree.
