Review Comment:
   that is a bizzare behavior. we should work on fixing comparison. I am not 
sure what is 'type_payload', but as far as file payloads are concerned, i think 
it's reasonably safe to compare file hashes + destination names; alternatively 
we can look and see why   the file path is different and if we should fix that 
instead. without any additional context and digging further, first option 
sounds more promising, second might be simpler but hackier and result in some 
other tech debt.
