Software repositories contain information about source code, software development processes, and team interactions. We combine provenance of the development process with code security analysis to automatically discover insights. This provides fast feedback on the software's design and security issues, which we evaluate on projects that are developed under time pressure, such as Germany's COVID-19 contact tracing app 'Corona-Warn-App'.
