All ten mutations of `site_standing` are red in test_watchdog.py and in nothing
else - the other 19 files are green under every one of them, which is the
measurement of how unpinned the line was.
One exception, recorded rather than dropped: in the batch run M10
(`sorted(standing.values())[-1]`) also reported FAIL test_peakguard.py. Re-run
in isolation three times and once more through tools/mutation_run.sh - four
clean passes. The batch script had discarded the failure detail so the check
cannot be named; what can be said is that it did not reproduce in four attempts
and that no claim in this card rests on it. That is CI-06's file behaving the
way CI-06 records.
