git blame Told Me I Wrote 767 Lines I Didn't Write

A developer recently discovered a misleading aspect of the 'git blame' command after integrating an automated document-generation gate into their workflow. While the tool attributed 767 lines of code to the author, the developer realized these lines were actually part of an upstream repository update. The article highlights how 'git blame' reports the last commit to touch a line rather than the original authorship, leading to potential confusion in collaborative or forked environments. The author uses this experience to discuss the importance of understanding tool limitations, particularly when dealing with automated systems and AI-generated content. By comparing this technical misunderstanding to the behavior of their own 'gate'—which blocks unsupported claims in generated documents—the author emphasizes that tools often answer different questions than users assume. The piece serves as a reminder to verify the provenance of code and data rather than relying solely on automated metadata.
