Linxira is built directly on Arch Linux. Native packages use pacman, the official Arch repositories, and the separate signed Linxira repository.
Shelly is the default graphical software manager after installation. It is optional post-install software, not an installer dependency; Calamares owns installation transactions.
AUR, Flatpak, and AppImage support are disabled by default and require explicit user opt-in. Catalog v2 records reviewed recommendations and source boundaries, while Shelly performs the approved package operations.
