[D] Are there REAL success stories of autonomous AI dev agents working reliably in production?

I’m having a serious debate with a colleague, and I want to settle this with actual evidence instead of opinions. The claim: That it’s possible today to run orchestrated AI developer agents (multiple agents, coordinated workflows) that can autonomously build and maintain software - under supervision of a senior AI/de - without running into unfixable errors or constant breakdowns. I’m skeptical. He believes it’s already happening.
