Your AI Agent Ran for Three Days. The Career Proof Is the Ledger You Kept.

An AI agent running for three days sounds impressive until an interviewer asks what happened during those three days. How was the objective bounded? Which branches failed? What evidence changed the plan? Who approved the risky action? Why should anyone trust the final result?

As agents become able to operate longer and coordinate more workers, the strongest career evidence is shifting from the output to the ledger that makes the work reconstructable.
