The persistence boundary for an answer value. bulkUpsert refuses kind: "null" because its
COALESCE would silently keep a stale value, so "nothing resolved" is written as an explicitly
empty answer, which replaces whatever the row held. Readers treat the two alike: nothing is
drawn and nothing counts as content.
