 ### Name project function namespaces by role
 
-Put pure project functions under `dotfiles.lib`.
-Put functions that create modules, systems, or assembly values under `dotfiles`.
+Put pure project functions under `flake.lib`.

 This keeps data-only functions separate from functions that carry flake context.
