The case concerns “Only believe what you can validate,” identified in the supplied evidence titles as a Microsoft article presenting Julia Kordick’s opinionated verification framework for agentic-AI outputs. The web results do not include that article: secondary sources instead describe Microsoft-related policy gates, human approval before tool execution, and middleware for input validation. These establish related control patterns, not the specific article’s mechanisms or demonstrated practicality; one source explicitly distinguishes authorization checks from validating business data, so approval should not be equated with output correctness.
