1 is what a process killed with TerminateProcess (and the plain failure of most programs) ends with, 3 what abort() ends with on Windows, so a fail or a timeout couldn't be told from a run that was killed or blew up. The codes other than pass now are 10 fail, 11 signal passed at danger, 12 timeout, 13 standstill and 14 error: none of them a code a process gets on its own, neither the shells' 126-127 nor 128 + a signal number on Linux. pass stays 0.
