## Overview

Yudao Cloud is a Spring Cloud business platform. Its user-facing flow is a client request into backend services, where authentication and shared framework concerns support domain operations and responses. The README documents a broad product surface—workflow, commerce, payments, reporting, collaboration, and enterprise modules—so these appear as distinct branches rather than an invented single transaction chain. The excerpts mainly show service interfaces, not controller wiring or implementations; edges between those layers are therefore omitted or marked unverified.
