The first release could keep a run and replay it. This one compares two of them: <code>codeinstances diff passing.instance failing.instance</code>.</p> <p>The usual case goes like this. A job works on Monday and fails on Tuesday, or passes on your laptop and fails in CI. You have both runs as instance files, because you put <code>codeinstances record</code> in front of the command. Now you want to know what was different, and you&rsquo;d rather not read two logs side by side and guess.</p>
