+
+## 项目概述
+
+基于 tianai-captcha 1.5.5 开源版的增强版行为验证码，目标是复现增强版全部功能并自建验证码服务平台。
+
+## 技术栈
+
+| 组件 | 版本 |
+|------|------|
+| JDK | 21 (Microsoft OpenJDK 21.0.11 LTS) |
+| Maven | 3.9.16 |
+| Spring Boot | 3.4.5 |
+| Lombok | 1.18.42 (后续逐步移除) |
+| SLF4J | 2.0.17 |
+| ONNX Runtime | 1.22.0 (ML推理，待引入) |
+
+## 环境路径
+
+```powershell
+$env:JAVA_HOME = "C:\Users\USER879511\.jdks\ms-21.0.11"
+$env:PATH = "$env:JAVA_HOME\bin;$env:PATH"
+$Maven = "D:\Middleware\environment\apache-maven-3.9.16\bin\mvn.cmd"
+```
+
+## 构建 & 验证
+
+```powershell
+$env:JAVA_HOME = "C:\Users\USER879511\.jdks\ms-21.0.11"
+& "D:\Middleware\environment\apache-maven-3.9.16\bin\mvn.cmd" -f "D:\tianai-captcha-enhanced\pom.xml" compile
+& "D:\Middleware\environment\apache-maven-3.9.16\bin\mvn.cmd" -f "D:\tianai-captcha-enhanced\pom.xml" package -DskipTests
+```
+
+## 项目版本
+
+从 `1.5.5` 升级到 `2.0.0-SNAPSHOT`，表示这是增强版的开发版本。
+

+- 包结构遵循开源版: application/generator/validator/resource/interceptor/cache/common
+- 新增包: crypto/obfuscator/risk/site/ml
+- API 响应统一使用 ApiResponse<T>
+- 暂时保留 Lombok，后续逐步替换为手写 getter/setter
