// mounted into, started by an SDK that passed on none of Supercov's settings,
// or a worker the preload never reached -- has no runtime, and without one the
// first probe would throw. Such a process installs the runtime itself, with
// the run's settings read from beside this file and their paths moved to
// wherever the workspace is seen from here, so its coverage lands in the
// run's own evidence directory.
