What's the issue?

Each AMP release contains a listing of all files that are included in the release, but it is incomplete. Some files exist in the CDN release folder that are not generated by the build process: gulp dist.

How do we reproduce the issue?

1. Build AMP release 1910161528000 locally: git checkout 1910161528000 and gulp dist
2. Verify all files generated by the build process are included in https://cdn.ampproject.org/rtv/011910161528000/files.txt
3. Notice https://cdn.ampproject.org/rtv/011910161528000/v0/validator.js exists but v0/validator.js is not one of the files generated by gulp dist (and hence not in files.txt)

Additional context

Having a complete list of files included in each release would be helpful for self-hosting the amp-runtime, see issue #25873 .

mattwomple thanks erwinm. to your knowledge, is validator.js the only additional file available from the CDN beyond what gulp dist outputs?
erwinm That's accessible through the cdn? I believe there are a few other artifacts. One i can think of for example is viewer integration scripts for the Android google app
