+The two halves no longer cross. `member` used to be `unique(user_id,
+hackathon_id)`, which welded a paid year to an edition: the day the next
+hackathon opened, every paying member read as a non-member. It is now
+`unique(user_id)` and a membership is defined entirely by its own dates, with
+`membership_history` recording which years somebody held one. The club half
+therefore works with no hackathon in the database at all.
