You certainly can ask it to produce a verifiable report that tells you how to verify its claims. Yes, you do need to verify the results and confirm you agree with it. I do this sort of thing a lot to discover misunderstandings Claude has about things and iterating on them. There's a difference between reading everything yourself vs having a discussion where one of you (Claude) will happily dig through everything and create detailed memos for review. If you want line numbers as evidence, just ask then verify, etc.
