1Find one owner's data in a shared artifact with needles built from that owner's records, replace each hit with the role it plays, and report which commits still carry it.

3## Goal
4 
5A shared artifact (a public repository, a template, a fixture set, a deliverable) holds nothing that belongs to one person or one organization, and still works: each leaked value is replaced by the role it plays or a placeholder that exercises the same code, or kept with a stated reason when it is already public. The working tree is changed only through a recorded decision file, so a rerun replays the same decisions. History is never rewritten here: the run lists the commits whose contents or messages carry a needle and names the decision the owner has to make about them.

7The scope is what the human named: one artifact and one owner. The run never picks its own target or widens either.
