Developers want a fast CLI to see code authorship and ownership across a whole repo at scale

A Show HN for a git authorship CLI that does industrial-scale git blaming reached 252 points and 127 comments, showing strong appetite for understanding who wrote and owns what across a large codebase. Plain git blame is per-file and slow, and finding the right reviewer, the de facto owner of a module, or who to ask about a bug is painful in big repos. The buildable gap is a CLI that aggregates blame and history across directories to surface real ownership, reviewer suggestions, and bus-factor risk quickly.
