Codex should be reviewing the E2E test artifacts (e.g. videos) and ensure they are in sync with the CUJs.
I thought I had added reviewer guidelines to AGENTS.md but I guess not.
Not sure if there is additional work we'd need to do to make the testing assets e.g. movie available to codex.
As an example
Here's a run where the movie produced shows the runner getting added in the console

https://storage.googleapis.com/runme-dev-assets/cuj-runs/runmedev-web/22084787987/1/index.html
This is an explicit step in the CUJ
At some point the movie stopped showing it
Codex should have caught that and prevented it
I think it likely got broken by
