> FSO directory deletion over reports purge metrics when a batch Ratis submit
> fails

> h3. Finding
> optimizeDirDeletesAndSubmitRequest discards the batching result and
> increments deletion counters and operator metrics (numDirsSentForPurge, INFO
> log, AOS/snap last-run metrics) for the full pre-batch list even when a later
> batch's Ratis submit returns non-success, so only committed batches are
> durable while metrics over-report; the drift is cumulative and never
> reconciled. The deletion itself self-corrects via retry, no data corruption.
> h3. Classification
> * Verdict: REPRODUCED
> * Severity: Medium
> * Source: Specula TLA+ model checking and confirmation debate, finding CR-7
> h3. Reproduce
