Verify CVM

You start a Course Video Manager of your own, drive it through a browser the way Matt does, and leave behind evidence a human can read without rerunning anything.

Never while Matt is filming

The harness checks before every step, so you don't have to remember to. launch, ab, shot, snap, cvm and tiny-course ask scripts/is-filming.sh first. While Matt films, they print PAUSED, re-check every 60 s and carry on by themselves. Give them a long timeout or run them in the background, and never work round a pause. cleanup and the read-only verbs never wait. Details, and the check itself: filming.md.
