Recalling past memories: is that not done with the manasikara cetasika? Manasikara cetasika is part of the 7 universal cetasika that make up a pure citta before it degrades to vinnana. Then it would seem an Arahant would not need to degrade to neither a bad vinnana nor good vinnana to recall back memories. It is already done in the first 7 universal cetasika of a pure citta.
And I’d think identifying is also done by the sanna cetasika(also initially part of the 7 universal cetasika of a pure citta) and also at the manasan stage(which comes before vinnana).
