Three consecutive full-lane runs on the same tree each failed a DIFFERENT file,
every one passing in isolation, with hook timeouts arriving alongside PostgreSQL
'Failed query' warnings from two api lanes sharing one database. That is the same
class FN-9131 investigated for core's loaded PostgreSQL directory.
Deliberately not quarantined: quarantine is file-level and the failing file moves,
so it would evict healthy coverage without touching the cause. Recorded with the
evidence so the next person does not re-derive it, and so the rescue is aimed at
the lane runner's connection/concurrency budget rather than at whichever test lost
the race that run.
