Subscriptions

A subscription links a subscriber to a plan.

A subscriber has at most one active subscription at a time. Canceled rows remain after a plan change.

Action	Effect
Create	Subscriber entitled via plan grants (status active)
Change plan	Ends the current subscription and starts a new active one
Cancel	Status → canceled; plan grants no longer apply (overrides may still apply)

Canceling a subscription does not clear overrides unless you delete them.
