@Internal
public CoreTransactionGetResult(String id,
 @Nullable
 byte[] content,

 Optional<String> crc32OfGet)

Note that it's intentionally obfuscated here as to whether both content and userFlags come from the document's current body, or staged in the transactional metadata. The MAV read resolution has been performed by this point.

Parameters:

content - will be nullable for tombstones, and some niche cases like REMOVE to REPLACE on same doc
