The edit is a JSON file

Don't hand-author a one-off filter_complex for a multi-cut edit and throw it away. Write the edit as edit.json — a list of clips with src, start, end, and a written rationale — and let one command execute it:

uv run video-agent edl edit.json -o out.mp4

Why: the edit becomes text you can read, diff, and re-render. A revision is "change two numbers and re-run," not "reconstruct the filtergraph." The rationale field forces you to write down why each cut was made (which take won, why the others lost, why the cut point sits where it does) — better decisions and an inspectable trail for the user.
