Why AI Assistants Write This Bug
Custom server configs and API routes serve static assets with no-cache headers, causing repeat downloads on every page view.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
