The Gemini Agent Is a Private Preview. The Governance Stack Around It Is the Real Announcement.

The October 8, 2026, announcement of the Gemini agent introduced a vision for a single, universal agent for work. As a product story, it is a private preview with no firm availability date. As an infrastructure story, it is a finished governance stack. Google has answered the agent-registry gap with a complete set of controls: cryptographically attested per-agent identity, OAuth-mapped authorization, agent-attributed audit, sandboxed execution, and Agent Gateway policy-once runtime enforcement. This stack is delivered inside a walled preview where every registry is a Google-run vendor registry.
