Each vat is a Durable Object that stores code by hash and runs it as a facet through the Worker Loader: an empty env, no fetch, storage that carries over upgrades. Two sockets with no configured address: whoever starts workerd hands them in (systemd socket activation), so the admin socket is the authority to install code. Tests run a real workerd: install, upgrade, isolation between vats, no fetch, the public port can't install, and code and state survive a crash. They spawn the package binary rather than the .bin shim, which forks workerd, so killing the shim orphaned it and the test run never ended.
