Othismo: A Runtime for Sandboxed Objects

About

Othismo runs images, which are sets of sandboxed AssemblyScript objects that can reach each other only through paths in their own Plan 9 style namespaces. If the image does not place something in an object's view, the object cannot reach it. The console, TCP and files are runtime-implemented servers granted only as the image requires, and a check command prints the most each object can reach. This separates computation from side effects, which helps when reviewing agent-written code that is too large to read in full.
