Yeah, so this package itself is the core framework that establishes how these tests are to be run. There is a notion of plug-ins, which are parsers and checks.

Then checks run over that structure and pull data in from elsewhere and run actual validations. You can read more in the developing plugins doc on the repo https://github.com/tinystacks/precloud/blob/main/DEVELOPING_....
