 ## Workstation v0 goals
 
 - CLI-first developer experience with keyboard-first navigation.
 - GNOME baseline customization via GSettings and pinned extensions (no GNOME core forks).
 - Open-source launcher palette (Wayland-first): `sourceos palette` uses fuzzel (primary) with wofi/rofi fallbacks.
+- Lampstand-backed local search surface via `sourceos search`, with the launcher treated as an action bus rather than a second filesystem index.
 - Primary keyboard remap lane: `input-remapper` on Fedora/GNOME.
 - Compatibility remap lanes: `xremap` and `kinto` (explicit compatibility path, not default).
 - Touchpad gesture lane: `fusuma`.

 ## Nix-first support
 
 This repository is Nix-native. A dev shell is provided:

+Lampstand is also exposed as a Nix package:
+
+  nix build .#lampstand
+
 Notes:
+- The workstation devShell includes the repo-local Lampstand package in addition to best-effort nixpkgs CLI tools.
 - The workstation devShell is best-effort; missing nixpkgs attrs will be reported on entry.
 - The profile installers still support non-Nix systems using dnf/rpm-ostree and brew where applicable.

 - Workstation v0 avoids non-open launchers.
 - Launcher install is best-effort via distro packages (Fedora: fuzzel) and does not silently enable third-party repos.
 - Kinto is treated as an explicit compatibility lane rather than the default Wayland-first path.
+- File search should resolve through Lampstand when available; the launcher must not run a redundant second file-search pass.
+- Lampstand is installed in user space and exposed through a user service, not as a mandatory host-system package.
