Replay runs a program against the whole recording. Fork runs it against the recording up to a step you pick, then lets it carry on from there. You get the past exactly as it happened, and a new future.</p> <p>Two uses pull this in. The first is picking up where a run went wrong. An agent ran for twenty minutes, called a dozen APIs, and on call nine it got an answer that sent it the wrong way. You don&rsquo;t want to spend another twenty minutes and another dozen calls getting back to call nine. <code>codeinstances fork -at 9 run.instance</code> answers calls one to eight from the recording in a moment, then sends call nine for real, against today&rsquo;s servers.</p>
