 ## Global Constraints
 
 - Do **not** modify `machines/configuration.nix`. `inputs` and `self` are already threaded into every module via `_module.args`; consume them as module arguments.
+- **Top-level `imports` must reference flake modules via `self.inputs.*`, not `inputs.*`.** `self` is a specialArg (available during `imports` resolution); `inputs` comes from `_module.args` (config-derived) and using it in an `imports` list causes infinite recursion. Inside the `config` body (including nested `home-manager.users.<name>.imports`), either `inputs` or `self.inputs` is fine.
 - Base channel is pinned `nixpkgs/nixos-26.05`; `pkgs.unstable` overlay is available everywhere. quickshell must come from `pkgs.unstable.quickshell` (needs ≥ 0.3.0).
 - home-manager scoped to user `finn` only; `home.stateVersion = "26.05"`.
 - Follow the existing profile pattern exactly: `let cfg = config.my.profiles.<name>; in { options.my.profiles.<name>.enable = lib.mkEnableOption "..."; config = lib.mkIf cfg.enable { ... }; }`.
