I had a podcast pipeline I was proud of. It took a transcript, turned it into a two-person conversation with text-to-speech, laid in the music, and produced an MP3 I could publish. I'd built it in one app, and it worked. I loved the output.

So when I started a second app that needed the same flow, I didn't want to rebuild the pipeline. I already had one. I just wanted it over there. So I asked the AI to copy it. And it did.

Here's the part that matters: I didn't just copy it and hope. I checked. I opened a fresh session (a clean one, no memory of the first) and told it to look at the new pipeline and make sure everything was right. It went and looked. It came back and told me everything was good.

Everything looked good. Or so I was told.

Then I loaded the first real transcript and ran it.
