The first build's clips are on the [build clips](clips.md) page.++> The silkscreen clip starts part way in: the first 23 label groups (the contact labels and TP1/TP2) went on before the recorder started, because `capture start` looked for the editor window that had been closed for the offline half. aiflow 0.1.38 fixes that.
