Handles checkout.session.completed, customer.subscription.updated, customer.subscription.deleted, invoice.paid, invoice.payment_succeeded, and invoice.payment_failed. A trial checkout stores status trialing and can issue a key. invoice.paid or invoice.payment_succeeded with amount_paid above zero stores active from trialing or past_due. A zero-amount invoice does not. customer.subscription.updated with status past_due, unpaid, or paused stores past_due without waiting for invoice.payment_failed. A trial key then returns 402 until a later paid invoice or an active subscription update. A subscription plan follows the subscription''s current price: lookup key, then a configured price id. A later event, or a redelivery whose price or status disagrees with the stored row, corrects that row. An older event does not move a newer plan backward. A credit pack is applied once per event id. A subscription checkout for a different subscription is logged and does not replace the stored subscription. A second trial for the same email or customer is not given a key. An event for a complimentary key is ignored. Omitted when live billing is off.'
