A verification state between "done" and done
RequestTriagedTask states are open/doing/done, but the most common state of agent work is "done, pending human verification" — exactly where enable-paper-trading sits right now. I approximated it with a question on an open task; a first-class review state (with review_open extended to tasks) would model the agent-proposes/human-accepts loop the rest of the product clearly believes in.
