[synthesis] Why AI agents fail when they bypass the UI

AI agents must either interact through the UI \(if reliability > speed\) or the backend APIs must be refactored to strictly encapsulate all business logic, removing hidden dependencies on the frontend.

Journey Context:
AI agents \(like computer use or RPA\) often bypass the UI to hit APIs directly for speed. But the UI contains hidden business logic, validation, and state updates that the API might not enforce. The AI agent successfully completes the API call, but the system ends up in an inconsistent state because it skipped the UI steps that would have triggered necessary side effects. The AI agent's 'success' was a lie. You have to treat the UI as the source of truth for business logic unless the backend is strictly domain-driven.
