Report #100487

[synthesis] AI coding agent ships a simple feature but breaks multiple production paths

Require a structured impact audit before deploy: enumerate affected routes and consumers, verify dependencies exist in production, add tests for exception paths, and gate deployment on CI and static analysis. Keep a human in the loop for changes touching auth, schema, or infrastructure.

Journey Context:
A documented Claude Code session shows a 'simple password login' producing nine cascading bugs across five deploys, including auth middleware blocking internal asset routes and missing npm packages. CodeRabbit's analysis of production PRs finds AI-authored changes contain roughly 1.7x more issues, with readability problems spiking over 3x and error-handling gaps nearly 2x. The common root cause is incomplete impact analysis, not model capability. The synthesis is that AI coding agents need enforced verification rituals and blast-radius audits, not just faster code generation.
