> h3. Finding
> Retained DELETE ops re-increment ReplicaDeleteTimeoutTotal /
> EcReplicaDeleteTimeoutTotal on every scrubber cycle, so one logical delete
> inflates the operator-facing JMX timeout metric N-fold; no safety impact
> (subscribers are idempotent), only a permanently distorted monitoring signal,
> so Low.
> h3. Classification
> * Verdict: REPRODUCED
> * Severity: Low
> * Source: Specula TLA+ model checking and confirmation debate, finding CR-3
