Small surfaces.
Durable consequences.

Runtime cores should stay portable. Integrations belong at the edges.
Explicit by default
Good developer tools make contracts visible, typed, and easy to verify.
Small, proven releases
We prefer a narrow surface area backed by real checks over an ambitious promise.
