Cloudflare's AI Blocked 16,000 Changes for Violating Engineering Standards
Cloudflare now treats engineering standards as executable policy, not documentation. Since the start of 2026, its AI code reviewer flagged nearly 230,000 deviations, withholding approval on roughly 16,000 changes. Standards live as structured RFCs in the Codex repository, with MUST vs SHOULD rules that progress from guidance to observation to enforcement. The payoff is a feedback loop where incidents and operational experience keep rewriting the rules.
