> h3. Finding
> The container delete path leaves a zombie recoveringContainerMap entry (no
> removeRecoveringContainer call). If the mask were absent the stale entry
> would drive the pre-HDDS-7842 unguarded scrub to NPE; at HEAD the consequence
> is prevented by the scrub null guard plus non-reused container IDs plus the
> HDDS-15791 auto-create rejection. Reachable via the public force-delete API
> but a hygiene/defensive gap only.
> h3. Classification
> * Verdict: MASKED
> * Severity: Low
> * Source: Specula TLA+ model checking and confirmation debate, finding MC-3
> h3. Reproduce
