-- The Oura account id behind a connection.
--
-- Read from `personal_info` at connect, so a connect that would attach an
-- Oura account another record already holds can be refused. Nullable and
-- unset for every existing row: a current connection is never asked to
-- reconnect, the id fills in at its next connect.
