+// and a response_text field for the new submit_text requirement type.
+// `status` is added as STRING + an explicit CHECK constraint, matching the
+// pattern task_progress.type already uses on this CockroachDB instance
+// (createTable auto-generates `check_type`; addColumn does not, so we add it
+// ourselves) rather than the ENUM-with-no-constraint gap task_requirements.type
+// happens to have today.
