Does the cache as a time to live? For example, would a source from 2020 in 20 years still be available on the build farms?

Okay great then. Maybe it would be a good idea to test this by simulating the deletion of a Gitlab repo. Better find it out now than when it's too late. -- Olivier Dion oldiob.dev
