June 2025 (2025-06) monthly summary for Shopify/nixpkgs: Focused on stabilizing packaging workflows for WIVRN Dashboard to improve build reliability and deployment consistency. The primary deliverable was a packaging script stabilization that prevents double-wrapping of the WIVRN Dashboard, achieved by switching the wrapping logic from postFixup to preFixup and adopting wrapQtApp instead of wrapProgram. This change ensures correct library paths and removes redundant configurations, reducing packaging regressions and manual intervention in releases.
