Review Comment:
Sorry I missed this on my prior reviews, but shouldn't unknown be treated as
null and return null for any cases that require a hash (also was `bucket[N]`
included to be defined for 'unknown' if not then I think the only other case is
puffin files which are today always defined as the hash of the values)?
