-- Translations never gate a release. Translate a new entry in a follow-up PR, or in the changelog commit when you can.
-- A translated entry uses the English heading unchanged: `## X.Y.Z - YYYY-MM-DD`. The website uses it only while the version and date both match the English entry. Otherwise it shows that release whole in English under a notice, so a beta rewritten in place drops its old translation until the new notes are translated. Delete Chinese entries whose English entry was renamed.
+- The release agent writes the Chinese entry in the changelog commit, after the English entry is approved. Every beta that rewrites the English entry rewrites the Chinese one too, and promotion renames both. `packages/website/e2e/i18n.spec.ts` fails CI on the release commit when any entry has no current translation.
