+**Defined:** 2026-03-18
+**Core Value:** 绕过知乎反爬检测，让爬虫正常工作
+
+## v1 Requirements
+
+### 指纹伪装 (Stealth)
+
+- [x] **STEALTH-01**: 隐藏 navigator.webdriver 属性
+- [x] **STEALTH-02**: 移除 Playwright 特有的 JS 属性（__playwright, pwInspect 等）
+- [x] **STEALTH-03**: 模拟正常浏览器的 Chrome 属性
+- [x] **STEALTH-04**: 修改 User-Agent 为正常浏览器格式

+
+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| 其他平台适配 | 本里程碑只针对知乎 |
+| 验证码识别 | 知乎主要用二维码登录，验证码场景少 |
+| 代理池扩展 | v1.3 已实现，本版本不改动 |
+| 行为伪装（鼠标轨迹等） | 先用最小改动验证效果，如需要再加 |
+
+## Traceability

+
+## ✅ v1.4 Zhihu Anti-Crawler (SHIPPED 2026-03-18)
+
+**Milestone Goal:** 绕过知乎反爬检测，让 Playwright 爬虫能正常工作
