Linus Torvalds merged something quietly significant into the Linux kernel tree: an official document titled AI Coding Assistants. It's not a policy debate. It's not a blog post. It's a .rst file sitting in Documentation/process/ right next to coding-style.rst and submitting-patches.rst.
The world's largest open-source project — 30+ million lines of code, thousands of contributors — just formally defined how AI can (and can't) participate in kernel development.
This isn't a niche Linux story. It's a blueprint that every engineering team dealing with AI-assisted code will eventually need.
