+## The clipboard: xclip and greenclip
+
+**Measured:**
+
+- **greenclip** keeps the clipboard's history, and rofi shows it on a key binding.
+- **greenclip is not in the official repositories.**
+- It is started two ways: the window manager's configuration starts it on both workstations, and on
+  one a user unit is enabled as well.
+- Its configuration names an absolute home path.
+- **xclip** (official) is the command-line clipboard the operator's scripts use.
+
+**Starting position:**
+
+- **`xclip` is a module of its own,** a package and nothing else. It is the tool scripts depend on,
+  and a module that needs it requires it.
+- **The clipboard manager holds `node-clipboard`:** its daemon, started once by the session (a session
+  contribution, or a user unit once user-scoped units ship, never both), its configuration with no
+  absolute path, and its menu binding contributed to the window manager.
+- **Which manager holds it is the operator's choice:**
+  - greenclip, as today, shipped under ADR 0205;
+  - or `clipmenu` (official), which feeds the same dmenu-compatible command as the launcher seat above,
+    and needs no archive.
+- **On Wayland** the same seat is held by `cliphist` with `wl-clipboard`, both official.
