Found the biggest gap where one of the arms was waiting and redistributed the tasks better

I concluded that eight parts was the minimum: either you use the two bespoke vitae and mors inputs, or you use an animismus which cannot fully be accessed with one arm and no track. Therefore I concluded that animismus with two piston arms was the way to go. Two arms is faster than one right? Surely the top solves don't have a hexarm on a convoluted track, performing machinations beyond my comprehension...
