Scripts

Objects in The Wired can carry behavior as WebAssembly scripts. A script is called on three fixed entry points: init, once on load; update, once per rendered frame; and fixed-update, on a fixed interval independent of frame rate.

Scripts are sandboxed. They act on the world only through the interfaces a host exposes to them, with no ambient network or filesystem access.

Trust

A script is granted a fixed set of interfaces when loaded — a capability list, fixed at load time. The space owner decides which documents, and therefore which scripts, are loaded into a space.

Portability

Scripts compile to a single WebAssembly binary, stored as a blob and loaded from that one blob by any UNAVI client — desktop, VR, or web.
