Advanced reasoning systems increasingly suppress operational transparency, breaking the historical link between surface signals and assistant outputs. As models move from retrieval toward latent reasoning, enterprises cannot infer visibility, ranking, or selection logic from traditional content signals. This paper outlines the structural forces driving the disappearance of the optimization layer and identifies the governance implications for organizations that rely on assistants for discovery, interpretation, and delegated decision making.
