02 / How we work

Framework-neutral

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.
