Caveats

A subscriber with multiple overlapping subscriptions does not churn until the last one ends.
member.churned does not delete the subscriber row; if they re-subscribe later, member.joined fires for the new subscription.

subscription.expired — typical predecessor.
member.joined — fires if the subscriber returns.
