Terminate paths read the environment, not your patch, so the same build can die in one setup and live in another. Adds the common probes (ptrace/TracerPid, replaced parent, SIGSTOP/SIGTRAP, instrumentation artifacts, non-standard environment), the two consequences that invalidate experiments (a pass under translation is not a pass on hardware; your own tooling can be what trips the check), and the rule to run the unmodified original through identical conditions first.
