In December 2024, Christian Obittner refactored the verification logic in the edgelesssys/contrast repository by extracting it from the CLI and consolidating it into a new SDK package. This modular approach, implemented in Go and leveraging Go Modules and build tags, established a single source of truth for verification, enabling both CLI and future SDK clients to share the same logic. By marking the SDK as unstable and internal, Christian allowed for safer experimentation and API evolution without disrupting existing workflows. The work laid a foundation for broader SDK adoption and streamlined downstream integrations, demonstrating thoughtful, maintainable engineering within a short timeframe.
