| # Simulates end users verifying builds published by Dfinity: | |
| # - Runs docker builds on various different operating systems, with an empty docker cache. | |
| # Note: This makes builds slow but is more representative of the end user experience. | |
| # - Verifies that all these builds yield the same artifacts. | |
| # - NOT DONE: Verify that these builds match our release artifacts. This would correspond to third | |
| # party verifiers getting consistent hashes that differ from our release. | |
