I'd disagree there : "trash" on Salsette is meant to be the name of an instant, not of a § in the rules.
This was the main mess and disagrement with that card : if "trash" there meant "what is called the trash event" like it's described in the rules, then CTM wouldn't care.
There, "access cards" should also be the name of an instant, not of the §. Therefor, should only work in archives, or any kind of multiaccess if there were a comma.
Proper access happens one by one and therefor triggers "access card" multiple times, and this doesn't trigger Aumukua multiple times.
I totally understand your point, and could totally agree with you if it is ruled like you say.
This is just how I could rule this if I were TO without any clarification on this - and I'm never TO so don't worry.
That kind of card with points get back & forth rulings. See Scavenge triggering trash before reinstall or not and other effects.
Both cards being strong and in the same faction should call a rapid answer anyway
