Publish

One finished video out, on the creator's own accounts. Making it is /short-editing.

Nothing is posted before the creator's explicit yes on the plan of step 5. That yes covers that video only.

Talk to them in their language. <edit> = video-agent/edits/<slug>/.

1. Which video

First match wins:

1. A path, a slug or a title they give: <edit>/output/<name>.mp4 (<edit> = video-agent/edits/<name>/, never the -rough cut).
2. The video finished in this conversation.
3. Nothing: the newest video-agent/edits/*/output/*.mp4 (not -rough). Name it in the plan.

<video> below = that file; post.md sits next to it in output/.

Then check <edit>/published.md: already there with this platform, say so and stop (unless they want to post it again).
