subscription.cancelled

When this fires

Cancellation is recorded by the subscriber or creator. The subscription remains active and the subscriber retains access until ends_at; after that, subscription.expired fires.

Required ability

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

Caveats

Cancellation is reversible until ends_at — see subscription.reactivated.
A renewal does not occur after cancellation; subscription.renewed will not fire.

subscription.expired — fires when the period ends.
subscription.reactivated — reverse path.
