+
+    This is a preparatory API change. Executions continue to evaluate growing
+    prefixes until final-trace verdict cadence ships. In particular, probes
+    still stop on the first detected prefix, so `ALL_TURNS` and negated
+    `ANY_TURN` cannot yet enforce requirements on prompts that were never
+    sent. Choose an explicit scope now so the evaluator's meaning remains
