A project team there are a few tasks. The team manager asks for the status of one from them. What's the right answer? The task isn't processed/handled. The task hasn't been processed/handled. Which verb would we use in this case?
It's the difference between thinking of "processed" as one possible status which the task constantly possesses, or thinking of "processed" as a thing which was done and is now over and in the past.
I think it's one of those cases in 21st century English where English speakers take a word that is one grammatical type, and stretch it a bit to make it another. "process" is a verb, and "processed" is the past tense of the verb, but "processed" can also be used as an adjective meaning "something which has been processed".
So both sentences are valid.
