 2. **部署必验** — 部署后不打开 K Tab 验证 = 部署未完成
 3. **不可见即不存在** — 组件不在 dashboard 中显示 = 等于没部署。离线不告警 = 监控缺陷
 4. **实现后同步 Spec** — 每轮开发完毕后，必须将 specs/{module}.json 更新为与实际实现一致的状态。文档过期 = 等于没写
+5. **部署目标即验收标准** — 所有代码必须以部署目标环境（Linux 246）为基准编写和测试。在本地开发机器（Windows/Mac）上跑通不等于验收通过。部署脚本、系统工具（`systemctl`/`crontab`/`ss`/`df`）、Python 版本、文件路径等都必须匹配 246 的实际环境。禁止使用 Windows 专属 API（`tasklist`、`netstat`、`schtasks`、`wmic`）在 246 部署的代码中
