Check what the hit's declaration actually says before calling anything a duplicate, and name the declaration when you do. +- Compare every headline against Tau Ceti as well as Mathlib. Read the supplied Tau Ceti source declarations, including their hypotheses and conclusion; a roadmap or module title alone is not proof of a duplicate. Name the existing declaration when blocking.

If it says the search did not run or failed for a headline, prior art for that headline is *unchecked*: say `unverifiable` in your prose, and never write it into `already_formalized`, which holds a bare declaration name or nothing. Not every overlap is duplication. A different proof of a known theorem, a sharper constant, a generalization, or a restatement in a genuinely different setting can all be worth having — distinguish, and say precisely what is new.
