+# Delete Chat History — cascade trigger deletion tests
+#
+# Flow:
+#  1. Login to get a Bearer token
+#  2. Create a project with 2 histories + 1 trigger
+#  3. Delete the FIRST history  → trigger must NOT be deleted
+#  4. Verify trigger still exists
+#  5. Delete the LAST history   → trigger MUST be deleted
+#  6. Verify trigger is gone (404)
+#  7. Edge case: delete a non-existent history (404)
