He asks: “Will extraterrestrial withdrawal then allow the akashic records to be cleaned and cleared, through our protocol work, eventually ending the phenomenon of retraumatization?” What can Creator tell us?

The protocol work is designed to work on all timelines and that includes all of the loopings brought about by time travel. That remains a work in progress. Humanity is still far behind and will not have fully healed everything prior to the Ascension. There will be enough progress to enable the Ascension to happen and that is a signal achievement of the greatest importance. The rest of the unhealed karma can be worked on indirectly while engaged in your future activities on a higher plane of existence, so you need not fear exiting when you have the opportunity; it is remaining as a physical human that keeps you in danger.
