Optional refund/dispute handler for subscription sellers who adjudicate reversals case by case rather than revoking automatically. When a Stripe charge is fully refunded (charge.refunded) or disputed (charge.dispute.created), it re-reads provider truth for the customer id and surfaces an in-app review notice naming that customer and the bound door — and changes nothing. You then decide whether to revoke that customer's access (Settings -> Seller). It rides the bounded Stripe for Sellers surface, never the full API front door, and takes no payment authority: every customer id is a fresh provider read, never the webhook payload. This is one of two install variants — install the revoke pack instead if you always close access when a charge is reversed.
