(Data Integrity & Race Conditions) | Duplicate active bookings allowed during payment intent creation and confirmation race; unhandled SQLSTATE `23505` threw unhandled HTTP 500 error | 1. Added pre-intent check in `createUpiPaymentIntent` rejecting active bookings with 409 `already_booked`.
2. Re-checked active bookings inside locked transaction in `applySuccessfulUpiPayment`, transitioning payment to `refund_pending` with reason `duplicate_booking` (0 bookings created).
3. Wrapped confirmation booking creation in `SAVEPOINT sp_confirm_booking` to catch SQLSTATE `23505` without HTTP 500.
4. Applied identical 409 protection and savepoint recovery to `claimUpiBooking` | [`lib/services/upi-payments.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/services/upi-payments.js) | `test/upi-checkout.test.js` (`REV-02` tests: intent creation 409, confirmation race `refund_pending`, guest claim 409, and SQLSTATE 23505 catch) | +| **REV-03** | **MERGE BLOCKER**
(Financial Operations) | Payments stuck in `refund_pending` had no operational recovery path; payments could not be refunded unless `succeeded`; provider refund failures rolled back audit state | 1. Permitted refund processing for both `succeeded` and `refund_pending` payments in `refundUpiOrder`.
2. Preserved audit ledger and idempotency (`status: 'refunded', duplicate: true`).
3. Moved external gateway network call outside DB holding transaction to avoid locking rows during gateway network I/O.
4. Caught provider network failures and persisted `refund_pending` with `failure_reason = 'refund_failed: ...'`.
5. Added authorized manual finance reconciliation mechanism (`manualReconciliation: true`) allowing finance officers to resolve stuck or failed refunds | [`lib/services/upi-payments.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/services/upi-payments.js), [`lib/services/refunds.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/services/refunds.js) | `test/upi-checkout.test.js` (`REV-03` tests: operational recovery from `refund_pending`, retry idempotency, provider 500 failure handling, and manual finance reconciliation) | +| **REV-04** | **MERGE BLOCKER**
(Financial Security) | `applySuccessfulUpiPayment` could receive missing, non-numeric, or malformed amounts; underpayment or currency mismatch was not strictly defended | 1. Enforced strict validation: `verifiedAmountPaise` must be a safe positive integer (`Number.isSafeInteger(n) && n > 0`).
2. Strictly verified `verifiedAmountPaise === Number(payment.amount)`.
3. Enforced exact currency match (`INR`) and merchant ID match.
4. Transitioned payment to `disputed` on any failure, logged audit details, and issued 0 bookings or Telegram invites | [`lib/services/upi-payments.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/services/upi-payments.js) | `test/upi-checkout.test.js` (`REV-04` tests: rejected null, NaN, non-numeric string, negative amount, underpayment, currency mismatch; 0 bookings created) | +| **REV-05** | **Medium**
(User Experience & Conformance) | Overlong UPI URI payloads crashed generator with unhandled HTTP 500; `buildUpiUri` could truncate payment details | 1. Expanded QR version capacity up to Version 14 (362 bytes), comfortably fitting large UPI URIs with long merchant notes and order IDs.
2. Enforced byte-length check using `Buffer.byteLength(uri, 'utf8')` rather than character count.
3. Created `QrPayloadTooLargeError extends HttpError` returning structured HTTP 400 with user-facing validation message.
4. Ensured `buildUpiUri` never truncates payment details | [`lib/upi/qr.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/upi/qr.js), [`lib/upi/adapter.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/upi/adapter.js) | `test/upi-checkout.test.js` (`REV-05` test: 363-byte payload rejected with HTTP 400 `payload_too_large` error rather than 500) | +| **REV-06** | **Medium**
(Webhook Authentication) | PhonePe webhook could bypass merchant ID checks if `merchantId` was absent or mismatched configured merchant identity | 1. In `PhonePeAdapter.verifyWebhook`: strictly verified `data.merchantId === this.merchantId`.
2. Rejected missing, null, or mismatched merchant ID with HTTP 401 `PaymentAdapterError`.
3. In `MockUpiAdapter`: verified `merchantId` against configured adapter identity.
4. Propagated `merchantId` into `applySuccessfulUpiPayment` verification | [`lib/upi/adapter.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/upi/adapter.js), [`lib/services/upi-payments.js`](file:///Users/pradeepjakuraa/strangersmeetup/lib/services/upi-payments.js) | `test/upi-checkout.test.js` (`REV-06` tests: missing merchantId rejected with 401; mismatched merchantId rejected with 401; valid merchantId accepted) | +| **REV-07** | **Low**
(Database Performance) | Ticket-tier active hold query `activeTierPaymentHolds` lacked an exact matching composite index | 1. Created additive migration `017_payments_tier_holds_index.sql` adding partial index `idx_payments_active_tier_holds` on `payments (((raw_ref->>'ticketTypeId')::uuid), status, expires_at) WHERE status = 'pending'`.
2. Verified index matches query predicate exactly.
