+"""release_exit_note.py — the EXIT-NOTE TEMPLATE (Nick, 2026-10-08).
+
+The counterpart of the issue-entry template: when the pipeline earns a new
+version, this renders a PLAIN-ENGLISH summary of what was worked on and
+submitted, so version history reads without opening commits.
+
+Template (what the reader sees):
+    ## What changed in v<VERSION>
+
+    <aggregate paragraph — counts by kind, the headline of the wave>
+
+    ### What was worked on
+    - <commit subject, translated to plain English>
+
+    ### How it was verified
+    - contracts walked (BUILDER-...) / truth batteries / CI gates — one
+      line per verification kind found in the range
+
+Feed: git log v<last-tag>..HEAD (chore(release) bumps excluded), the
+conventional-commit prefix gives the kind; the subject's scope gives the
+plain-English translation. The release step calls render() and passes the
+result as `extra.improved`/`added`/`fixed` per kind, so the evidence-
+derived note carries the human narrative alongside the governed facts.
+
