Cloudflare, React, the AI SDK, Gemini, authentication, product UI, or Domain-specific fields.

Core invariant

Every durable state change enters as a typed Runtime Event and is reduced by pure logic before an adapter persists it. Models and tools can propose events; they cannot mutate state directly.

See Define a Domain and the package README.
