+### 2026-06-04 — frontend v2.8.89 — Mini App checkout flows straight into payment (shop model)
+
+Per the shop model (pay as part of ordering, not place-then-pay-later), the
+in-shell checkout now, after «ادامه و پرداخت», creates the request(s) (template
+conversion already mints + accepts an offer and sets selectedOfferId, status
+pending_payment) and for a SINGLE-request order jumps directly into the in-shell
+direct-transfer payment step (openPaymentRequestId) rather than dropping the
+buyer on the Requests list. Multi-request orders still go to Requests. Checkout
+reads the created request id from batch-convert's data[]; button relabeled to
+«ادامه و پرداخت». (The normal request→offers→pay escrow flow is unchanged.)
+**Verification:** tsc + eslint clean.
