This repository is primarily an open-source technical book and architecture knowledge base written in Chinese, rendered as a heavily customized VuePress static site. The core deliverable is the book itself — chapters spanning architecture history, distributed systems foundations, transactions, security, observability, service mesh, containers, and cloud-native infrastructure — rather than a runnable software service. It is best classified as a documentation/application hybrid: the only application code is the VuePress site infrastructure, custom plugins, CI/CD scripts, and an embedded resume slide-deck framework. The repository also links to external companion demo projects (Spring Boot, Spring Cloud, Kubernetes, Istio, serverless) rather than hosting them in-tree.
