Review day the canvas was full. Roles too: plan, retrieve, write-ticket, check. The job was turning a failure into a defect. In the window they told each other “please continue”. The tracker was empty. Turns rose. The bill jumped. Nobody had written a done condition. Without one the discussion group never stops. A group that will not stop looks like multi-agent collaboration. Looks like it, and in three months nobody dares turn it off.
