chord/next/http: a Web fetch handler built from the registry Http (routes, wraps, sockets, hosts, relays, CSP sources) and Authenticators, responses as descriptions, a security baseline on by default, Chord's own Node listener as a host-lifetime object, nodeRequest for apps mounting it, links and plugin sockets. chord/next/workers: a forked worker per address, started on demand, stopped when idle, never restarted by itself, plugins built by the server and shipped. Plugins: kinds with platform and host packages, createPluginRuntime, scripts(kind), rollout results per host, imports of other plugins by name. Kernel: RouteHandle (retry, suspend), no route backoff, anonymous host.root, origins only from relays. ws is an optional peer dependency.
