+ * asserts the generated JavaScript emits the corresponding runtime calls:
+ * {@code triggers_calls.txt} exercises {@code Trigger} (subflow invocation with bubbled-up
+ * result), and {@code structure.txt} exercises {@code RRF} (render-reply-fetch) and
+ * {@code RFAC} (redirect-fetch-at-callback). {@link ValidFlowsTest} only checks that these
