I am specifically handling the Failure case so that I can fire a Cmd that actually reports the error (via ports)

I'd do this:

ResultsReceived data ->
    ( { model | data = data }
    , case data of
       Failure err -> systemError <| toString err
       _ ->  Cmd.none
    )

I'd also consider systemError : a -> Cmd msg.

(ie. let it do the toString for you).
