+### 2026-06-04 — frontend v2.8.88 — in-shell direct-transfer payment (no wallet connection)
+
+Buyers can now pay a pending_payment request entirely inside the Mini App, with
+NO web3 wallet connection — mirroring the web «انتقال مستقیم» rail.
+TelegramPaymentView: resolves the selected offer (seller + amount) →
+getPaymentOptions for chain/token → createDirectBalanceIntent (provider
+amn.scanner, rail direct_balance, mode check) → shows a copyable derived deposit
+address + exact amount + a strong "send only this token on this network" warning
+→ «پرداخت کردم» calls checkDirectBalancePayment.
+Edge cases (all surfaced): OVERPAYMENT accepted (backend delta>=expected →
+paid); UNDERPAYMENT shows "received X of Y, send the rest" (paidDelta vs
+expectedAmount); WRONG TOKEN — the check flow can't detect a foreign token, so a
+prominent on-screen warning is shown (backend webhook rejects token/chain
+mismatch). Wired from the request-detail pay CTA via a new openPaymentRequestId
+shell overlay + BackButton. (Replaces the earlier "open web payment" hand-off.)
+**Verification:** tsc + eslint clean.
