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.

// Tests of the workers component (slice 10 §3, §4): starts on demand (the link made at the fork, `started` on
|
|
// `connect`, the start timer covering only the start), failures that stay (a crash, a `fatal`, a lost link, a failed
|
|
// start: no fork for a new hold, holders `failed { waiting }`) until `retry` or a rollout, idle stops and `busy`, `stop`
|
|
// and its suspension, the per-address queue, `close`, the rollout step, and nothing kept of 1,000 addresses.
