+**文档版本:** v1.2.0

-**状态:** 🟢 联盟返佣系统核心已完成（管理后台 UI 待补）
+**状态:** 🟢 联盟返佣 + 打赏（个人码捐赠）双变现模式已落地；付费订阅/付费 Skill/用量包已下线
 **负责人:** Hermes Agent

 ## 项目概览
 
-- **目标:** 构建联盟返佣系统，并将「技能广场」与推广链接打通，作为当前（无 ICP 经营许可证前）合规的主力变现路径
-- **合规定位:** 会员付费/付费 Skill 属经营性收费，需 ICP 经营许可证。在取证前，以**联盟返佣**（第三方平台结算佣金，非平台经营性收款）为主力变现，配合免费内容 + SEO
-- **范围:** 数据库模型（规范化）、后端 API（ORM，去 SQL 注入）、前端展示与点击追踪、单元测试、种子数据
+- **目标:** 在「无 ICP 经营许可证」阶段，将全部经营性收费（会员订阅、付费 Skill、沙箱用量包）下架，改为合规的「打赏（个人码捐赠）+ 联盟返佣」模式
+- **合规定位:** 会员付费/付费 Skill/虚拟商品属经营性收费，需 ICP 经营许可证。在取证前：以**联盟返佣**（第三方平台结算佣金，非平台经营性收款）为主力变现；以**打赏/捐赠**（个人收款码，自愿赠与，平台不提供对价）作为补充；所有内容（技能、练习、工具指南）保持免费开放
+- **范围:** 打赏数据模型与 API、前端 /donate 页、会员/技能广场/用量包三处付费面改造为免费+赞助、导航与页脚入口、单元测试、种子数据
