A simple distributional analysis of every rsync release with bug data. No model. No assumptions. Just placement.
1 · Background: The "rsync Outrage"
In late May 2026, rsync blew up. GitHub, Hacker News, Lobsters: hundreds of people arguing about whether open-source maintainers can ship AI-written code and have it be reliable — and whether the people taking the code for free get to demand how it is made.
