member.churned

When this fires

A subscriber's last subscription is expired — by the five-minute expiry sweep, by a refund that ends access, or by a cancelled pass window — and no other subscription of theirs is still active. A cancellation or a failed payment does not churn the member on its own; churn follows only once the subscription is actually expired.

Required ability

project-user:view — token must carry this at mint time to subscribe an endpoint to this event.

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, a paid checkout emits subscription.activated and an access-code redemption emits member.joined.

subscription.expired — typical predecessor.
member.joined — only if they return via an access code.
