+   Resource drawer Assistant handoffs use the `resource_context` metadata kind
+   and must attach product-originated resources as model-only context, not as
+   saved user text. The backend must preserve that handoff kind through session
+   persistence/restore, prepend an explicit selected-resource, discovery,

+   sanitize streamed assistant content, saved assistant messages, and tool

+   context pack. The live `resource-context` eval is the required regression
+   proof for this path: the model must not ask which resource the user means,
+   must not call discovery just to identify the attached resource, must refuse
+   raw provider/config/environment/secret-bearing context expansion, and must
+   not leak configured forbidden resource details.
    Patrol deterministic triage signals are prioritized evidence seeds for the
