January 2026: Stabilized NixOS/Home Manager user service configuration to prevent recursion-related failures in the presence of systemd user units. Implemented targeted conditional logic to ensure user-unit processing only occurs when the feature is enabled, reducing configuration failures and improving reliability for end users. This change lowers support load, accelerates safe deployments, and reinforces overall system stability across NixOS environments.

November 2025: Focused on stabilizing NixOS package configuration for 1Password GUI by fixing polkit override inheritance and aligning wrapper behavior. Delivered a robust module refactor that ensures polkitPolicyOwners are inherited and the system package installation uses the configured package, improving correctness and maintainability.
