def attach[F[_]](
      anchor: Session[F]
  )(implicit F: Async[F]): Resource[F, LiveServer[F]]
```

Listens through a control client attached to `anchor`, rebuilding on every announcement. The session is a required parameter: there is no arbitrary pick left to make, and a session that later disappears is `ServerMirror`'s own reconnect-or-`TargetGoneException` policy, surfaced through [[LiveServer#failure]] like any other cause.

## Parameters

- `anchor` (`Session[F]`)
- `F` (`Async[F]`)
