 ## Desktop
 
-- When adding a graphical application, register its workspace icon in `registry.window-icon`.
+- TODO: Verify this path after the NixOS configuration is migrated.
+  When adding a graphical application, add a `window-rewrite` icon mapping in `modules/desktop/session/waybar.nix`.
   The workspace indicator uses this mapping to show an application icon instead of the generic default glyph.
   Match the mapping on the window class.
-  Store the icon as the rendered string.
   Run `hyprctl clients -j | jq -r '.[].class' | sort -u` to list classes in the running session.
 - TODO: Verify this path after the NixOS configuration is migrated.
   Set Hyprland session environment variables in `modules/desktop/session/hyprland/default.nix` with `env = KEY,VALUE`.
