Embedded evaluators (a step Dario Amodei proposed in his September 2026 essay "We Must Pace the Frontier") go further than a one-time pre-deployment audit: groups like METR get desks, badges, laptops, and access to training pipelines and internal tooling comparable to an internal risk-assessment team, plus a contractual right to publish findings without the lab's editorial control. The model is borrowed from banking, where regulatory supervisors sometimes sit inside the institutions they oversee. The point is verifiability — any commitment to slow down or add safeguards is only as credible as a neutral party's ability to check it against what is actually happening on the inside, not just what a company chooses to disclose.
