The next step: open-source audits.
We plan to publish real audits as case studies with their own certificates. Each will identify an exact revision, a permitted reproduction, problems and limits. The aim is evidence another team can use when deciding what to delegate.
Our longer-term questions include meaningful oversight, faithful explanations and response to changing conditions. See the future research direction.
