 ### Rule
 
 Add flake inputs in `flake.nix`.
-Put root flake output composition in `src/flake/default.nix`.
-Keep `src/flake` focused on composing public outputs from implementation files it imports.
-Put project-specific package implementation in that project's source tree, for example
-`src/xatu/package.nix`.
-Put NixOS and dotfiles implementation in `src/dotfiles`.
-Use `flake.nix` to pass inputs into the root flake implementation.
+Put new flake output implementation in `src/flake/default.nix`.
+Use `flake.nix` to pass inputs into that implementation.
