E(vatAdmin).makeIngress(labels) reserves a mount and returns an ingress; whoever holds it serves requests carrying those labels by calling E(ingress).serve(handler). A vat gets one in its params, like any other remote object; nothing in a vat's module is an entrypoint. A request reaches the handler as passable data (method, path, labels, body), and the response comes back as data (status, headers, body). The handler is a live reference for now: after a restart its mount answers 503. vats/hello.js serves hello, world; pnpm hello creates it on a running toybox (client.js is the Node OCapN client, shared with the tests). pnpm start and pnpm switchboard never ran: systemd-socket-activate wants absolute paths for unix sockets.
