+### 2026-06-04 — frontend v2.8.81 — in-shell checkout (Mini App no longer hands off to web)
+
+Cart «ادامه و پرداخت» previously navigated the Telegram WebView to the web
+checkout (taking over the Mini App). New TelegramCheckoutView keeps it in-shell:
+order summary + delivery-address picker (reuses saved addresses; "add address"
+opens the in-shell addresses manager) → places the order via
+convertTemplatesToRequests({paymentConfirmed:false}) so requests are created in
+`pending_payment` (escrow model — NO on-chain/web3 transaction needed inside the
+Mini App). Cart cleared on success and the shell jumps to Requests, where the
+buyer completes the escrow payment. New 'checkout' shell overlay + cart `clear()`
+on the cart hook. Verified the deferred path exists (status 'pending_payment'
+when paymentConfirmed is false) rather than requiring batch-convert's
+paymentConfirmed:true on-chain flow.
+**Verification:** tsc + eslint clean.
