+
+            Maintainers (owner / member / collaborator) can control this PR
+            by leaving a comment with one of:
+
+            - `/gallery-agent recreate` — close this PR; the next scheduled
+              run will propose this model again (useful if the entry needs
+              to be regenerated with fresh metadata).
+            - `/gallery-agent blacklist` — close this PR and permanently
+              prevent the gallery agent from ever reproposing this model.
+
+            Plain "Close" (without a command) is treated as a no-op: the
+            model may be reproposed by a future run.
