How a program ended: an exit status or the signal that ended it.

One of the two is set, as for a Node child process: [`exitCode`](/en/ts/latest/reference/types-programexit-exitcode/) for a program
that exited, [`signalCode`](/en/ts/latest/reference/types-programexit-signalcode/) for one a signal ended. A program
[`Server.run`](/en/ts/latest/reference/server-server-run/) or [`Server.spawn`](/en/ts/latest/reference/server-server-spawn/) started runs under an `sh`, which
cannot tell a signal's death from the program exiting with 128 plus that
signal's number, so a program's own `exit 130` reads as `"SIGINT"`, as that
status means by convention.
