What is the SOP when you realise you have no spoilers?
No SOP, because there's no requirement for one, and it wouldn't work anyway...
Maybe we should rephrase this as "what is the SOP for a landing where the AB automation fails to recognize (for whatever reason) that the plane has landed and should be slowing down"... ?!
Again there was a big mistake in leaving the T/L above idle, but there might be other occurrence (such as a sensor malfunction) that will prevent spoiler / autobrake magic... what do you do then ??
