Does My Bug-Risk Model Still Work Once an AI Is Committing Code?

Churn, ownership concentration, and code coupling are old proxies, built from decades of human development patterns. An LLM doesn't get tired and doesn't lose context between commits the way a person does. I found Next.js — a repo with real, large-scale, ground-truth AI-assisted commit history — and checked whether my existing signals still know what they're looking at.
