It&rsquo;s <code>claude</code> or the <code>codex</code> app-server. That in turn spawns shells, <code>go test</code>, <code>npm</code> or whatever the task calls for. Two things have to be true about that tree. When a turn ends or gets killed, the <em>whole</em> tree goes, including the grandchildren. And if somebody sets a memory or CPU budget, the budget applies to the whole tree, not just the process I happened to start.</p>
