simon fce725e13c 初始提交:高股息策略研究与回测系统
从 Point-in-Time 股票筛选到统一 Web 前端的完整链路:
筛选 → 画像 → 策略 → 回测 → Walk-forward → 绩效分析 → 报告/前端。

架构
- 数据层与策略层分离;策略代码不写 SQL,只经 data/repo.py 取数
- 所有业务阈值集中在 config/*.yml,代码零硬编码(字段写错直接报错)
- 报告只做「run_id → SQL → 渲染」,不做任何计算,数字可追溯
- 前后端分离:output/ 静态站点 + hdiv web 提供的 REST API

数据安全
- 只增不删:SQL 钩子拦截 DELETE/DROP/TRUNCATE,并有源码扫描测试守护
- qlib 原有表只读,本项目数据写入 hd_ 前缀表
- 回补使用 INSERT IGNORE,保证既有行零改动
- .env 存密钥且已 gitignore;output/、logs/、.venv/ 不入库

交付物
- 30 张 hd_* 表、7 个 YAML 配置、283 项自动化测试
- 统一 Web 前端(hash 路由 SPA)+ nginx 部署配置与 launchd 托管脚本

如实声明的限制
- 策略缺少稳定的样本外超额收益(Walk-forward 7 窗口均值 -0.95%,
  基准 +2.29%);其价值体现在回撤控制,而非超额收益
- 涨跌停/停牌约束仅覆盖 2019 年起;index_weight 尚未填充
- AI Agent 层(plan.md 第四版 P8)未实现

详见 docs/user-guide.md 与 docs/implementation-status.md。

"""CLI 接口契约测试。
**为什么需要**:使用手册(``docs/user-guide.md``)里的命令就是用户看到的接口。
文档与实现脱节是极易发生且很难察觉的问题 —— 实测发现手册记载的
``hdiv sync financial --interleaved`` 在 CLI 中根本没有暴露,
而 ``hdiv ddl verify`` 的输出格式也与手册不符。
本测试把「手册承诺的接口」变成可执行断言:
只要有人删掉一个参数或改掉命令名,测试立刻失败。
