# desk-channel

The desk as a channel of the operator's conversation: kind `desktop` of the `channel` and `intake` benches the
router (`messenger`) declares (novox/hq ADR 0258, ADR 0259). It shows the router's messages on the notifier of
each machine the operator sits at (the `node-notifier` seat), and says which button was chosen there.

- **It proves nothing about who clicked.** Any process of the operator's account can choose a notification's
  action (`dunstctl action`), so its claim declares no `verified-sender`: the router offers here only
  acknowledgements (Silence for a week, Details) and says in the words where an approval can be given.
- **An answer is taken only on a machine its message was shown on**, and once; a refused click is said where it
  was made. A message with buttons stays until it is dismissed.
- **A notifier that started again** (`dunst.started`) is shown again every open message with buttons it showed.
- A message no machine took is said to the router as failed; the router tries it again.

## What the operator gives

The machines to show on, as a setting: `settings` for `desk-channel` with
`{"desktop-machines": ["<the machine the operator sits at>", …]}`. Until then it says it cannot send, and the
router sends warnings to the channel that reaches the operator away.

## Where it runs

Held once for the mesh, on the control node beside the router. It asks each machine's notifier through the
mesh: nothing new runs on the machines.
