Four corrections noted by the test plan's executor in commit 461b8d0:
- PID-lookup race: pgrep+head can pick the wrong instance. Replace
with systemctl show -p MainPID --value left4me-server@N.service.
- gdb-from-host ptrace check: nsenter into only the mount namespace
with root caps bypasses the SECCOMP filter, so the test is a false
positive. Replace with systemd-run-with-same-directives probe, or
syscall-filter inspection.
- D5 pgrep pattern: 'srcds_linux.*\@2' doesn't match because @N is
in the unit name, not argv. Use systemctl show -p MainPID.
- scmp_sys_resolver is in the seccomp package on Debian 13, not
libseccomp-dev.
