+### 2026-05-28 — backend@19f7eb9, frontend@60ee6fb — Task #10: AML screening (Chainalysis, seller-paid, seller opt-in)
+
+**Commits:** backend `441c8be` → `80ba046` → `19f7eb9` (2.6.46 → 2.6.47), frontend `717d5c8` → `b7540f5` → `60ee6fb` (2.6.46 → 2.6.47)
+**Touched:**
+- Backend: `src/services/payment/safety/amlProvider.ts`, `src/services/payment/safety/chainalysisProvider.ts`, `src/services/payment/safety/amlScreeningService.ts`, `src/services/payment/safety/transactionSafetyProvider.ts`, `src/services/payment/paymentCoordinator.ts`, `src/services/admin/amlConfigRoutes.ts`, `src/models/SellerOffer.ts`, `src/app.ts`, `.env.example`
+- Frontend: `src/sections/request/components/seller-steps/step-1-send-proposal.tsx`, `src/types/marketplace.ts`
+**Why:** Task #10 implementation. Chainalysis Public Sanctions API integration for seller-paid AML screening. Seller can opt-in per-offer via `requireAmlCheck` + `amlBlockOnFailure` toggles. `TransactionSafetyProvider` screens buyer source address after on-chain transfer verification. `paymentCoordinator` deducts `AML_CHECK_COST_USD` (default 0, API is free) from seller escrow on payment completion. Admin routes for AML config.
+**Verification:** Frontend `tsc --noEmit` clean. Backend relevant tests pass (module resolution issues in unrelated test files).
+**Linked docs updated:** [[02 - Data Models/SellerOffer]], [[03 - API Reference/Admin API]], [[04 - Flows/Escrow Flow]]
