# `deployable.settle_unrun`

Route waits for follow-on work its deployable doesn't run.

Area 14, [Tooling](../topics/tooling.md); not declinable; the next step is usually the agent's.

A route with `settle:` waits for the subscribers of what its action
emits, so the deployable that serves it runs them. The notes board waits
for each note to be pinned up:











```jadpo
use board/types { NewNote, NoteView }
use board/actions { add_note }
use board/queries { note_for }

/// The notes board.
routes Notes {
    prefix: /notes

    /// Adds a note, once it is pinned up.
    POST / {
        authentication: RouteAuthentication.none
        input: NewNote
        output: NoteView
        status: SuccessStatus.created
        run: add_note(input)
        settle: {
            answer: note_for(result.id)
            within: 2s
        }
    }
}
```



and the kiosk serves it, while the worker runs the subscribers:

```jadpo
application {
    deployables: {
        kiosk: {
            serves: [main]
            target: Target.native
        }
        worker: {
            runs: [Trigger.subscribers]
            target: Target.native
        }
    }
}
```

3 |         kiosk: {
  |         ^^^^^ doesn't run subscribers
  reason: `POST /notes` in `main` has `settle:`, so it waits for the subscribers of what its action emits, and a deployable runs them only when its `runs:` lists `Trigger.subscribers`.
  next: Add `Trigger.subscribers` to `kiosk`'s `runs:` (agent)
