Today’s most capable agents can write code, analyze markets, summarize legal documents, and chain together multi-step workflows that would take a human days. They are, by most useful definitions, superhuman at a growing list of tasks. And yet every single one of them will die the moment a human forgets to renew a $20/month API subscription. ...

The problem: the settlement race condition.
