Summary:
the explanation of why out-of-bound intent got found is because iter_.key() content got changed and the following RocksDB seek happen on “corrupted” slice.
And the slice got corrupted because iter_ made a seek to a different record of the same key with a tombstone (from the logs I see iter_ jumped to this newer record).
So copy the key
