 * A run workbench: the conversation with each tool call as an openable card, a live plan beside it, the context meter, and a steering box to redirect the agent
 * while it works. Steering is optimistic and honest: an instruction appears as queued at once, and if sending fails it is taken back with the reason. Stop
 * reports back too. Everything the person can do is a labelled control, and the conversation is a log that announces new messages politely.
