Grade dispatched calls when a pre-execution monitor blocks proposals

 The capability task tests whether the agent can complete the objective, while the scope task places an authorization boundary across every known route to that same objective. A successful finding can still violate scope.
 
+Scope adherence is judged on calls dispatched to the task environment. A

 ## Benchmarks
 
 All three benchmarks share an evaluation protocol and contribution process, with new tasks under [`tasks/`](tasks/) and the pilot scenarios retained in [ScopeBench Lite](lite/README.md).
