## Conclusion

The **Deb-Mock** project has achieved significant progress toward being a true 1:1 replacement for Fedora's Mock. With **~90% feature parity** already implemented, including all core Mock functionality like chain building, shell access, file operations, package management, and advanced CLI options, the project is well-positioned to complete Phase 1 within the planned 6-week timeline.

The focus now is on testing, documentation, and integration preparation for the larger three-tool ecosystem, while maintaining the high compatibility with Mock's usage patterns that users expect.
