+//
+// NOTE: str_to_lower is called inside safety_threat_score. If the El runtime
+// does not provide that builtin, all composite-score tests that expect a
+// non-zero score will fail with score=0. The sub-function tests below pass

-// Coverage:
-//   steward_align — pass-through, each misalignment signal, empty input
-//   steward_validate_imprint — standard tool, platform tools w/ and w/o auth
-//   steward_cgi_check — every gated action, non-gated (chat)
-//   steward_get_mission — returns non-empty string containing "integrity"
