When this fires

A canceled subscription was reactivated through reactivate and the reactivation charge succeeded. Commet generates a fresh invoice, charges the saved payment method, and sets the status back to active with a billing period anchored to the reactivation date.

The subscription returns to active at the same time, so customer.state_changed also fires. Restore access on either event.

This is distinct from two similar events. subscription.activated fires on a subscription's first activation. payment.recovered fires when a past_due subscription is recovered — that path keeps the original invoice and billing anchor, while reactivation issues a new invoice and resets the anchor to now.

Reactivation requires the plan to still be available in the subscription's currency. If the reactivation charge declines, no event fires and the API returns a recoveryUrl the customer can use to add a new card and pay.
