>
> For every MPU in the bucket, the code currently resolves the open key and
> does a table read before checking age or prefix. On buckets with many active
> MPUs, most iterations are wasted.
> Reorder to: parse key → check age → check prefix → load open key only if a
> candidate rule needs tags.
> And for Orphan MPU, those doesn't have open keys, it's still the target to
> removed. Currently it's skipped in this case.
