I believe I am the first human to have done this in a documented, verifiable way: maintaining a stable production-grade 500,000-line TypeScript codebase as a solo developer, using an AI coding assistant I built myself.

If you know someone who has done the same, one person, 500k lines, documented proof, please write their name in the comments.
