> h3. Finding
> After a routine OM upgrade, every pre-existing DONE snapshot-diff job
> deserializes with a null largestEntryKey, so the first client read of the
> report trips the integrity check and hits an uncaught NPE (wrong-key
> updateJobStatus) instead of the designed retriable error; the report is
> intact yet permanently unreadable and the job is stuck DONE (not
> resubmittable) until the retention TTL GC, affecting all old jobs broadly
> rather than via a rare race.
> h3. Classification
> * Verdict: REPRODUCED
> * Severity: Critical
> * Source: Specula TLA+ model checking and confirmation debate, finding CR-2
