+# 飞书每日工作汇报系统
+
+这是一个轻量的日报提交和浏览工具。员工通过飞书机器人提醒进入填写页提交日报，管理者在浏览页查看所有记录和未提交名单。
+
+## 本地启动
+
+本项目只使用 Python 标准库，不需要安装第三方依赖。
+
+```bash
+python -m daily_report.web
+```
+
+默认地址：
+
+- 提交页：http://localhost:8787/submit
+- 管理页：http://localhost:8787/manager
+
+## 配置
+
+复制 `.env.example` 为 `.env`，或直接设置环境变量：
+
+- `PORT`：服务端口，默认 `8787`
+- `BASE_URL`：飞书消息里使用的外部访问地址
+- `DATABASE_PATH`：SQLite 数据库路径
+- `EMPLOYEE_SEED_PATH`：员工名单 JSON 路径
+- `WORKDAY_CALENDAR_PATH`：国家法定工作日历 JSON 路径
+- `FEISHU_WEBHOOK_URL`：飞书自定义机器人 Webhook
+- `FEISHU_WEBHOOK_SECRET`：预留字段，后续用于签名校验
+- `FEISHU_APP_ID`：飞书企业自建应用的 App ID，用于自动识别填写人
+- `FEISHU_APP_SECRET`：飞书企业自建应用的 App Secret
+- `SESSION_SECRET`：本系统登录 Cookie 签名密钥，可以填一串自己生成的随机字符
+
+## 员工名单
+
+第一版通过 `data/employees.json` 维护员工名单。每个员工需要：
+
+- `feishu_user_id`
+- `name`
+- `department`
+- `manager`
+- `active`
+
+修改员工名单后，重启服务会自动同步到 SQLite。
+
+## 飞书机器人
+
+在飞书群添加自定义机器人后，将 Webhook 地址配置到 `FEISHU_WEBHOOK_URL`。
+
+手动发送提醒：
+
+```bash
+curl -X POST http://localhost:8787/api/robot/send-reminder
+```
+
+手动发送汇总：
+
+```bash
+curl -X POST http://localhost:8787/api/robot/send-summary -H "content-type: application/json" -d "{\"date\":\"2026-05-07\"}"
+```
+
+## 飞书自动识别填写人
+
+要让员工打开填写页时自动识别身份，需要使用飞书企业自建应用。
+
+在 `.env` 中填写：
+
+```dotenv
+FEISHU_APP_ID=你的 App ID
+FEISHU_APP_SECRET=你的 App Secret
+SESSION_SECRET=任意一串较长随机字符
+```
+
+然后在飞书开放平台应用后台配置网页应用重定向地址：
+
+```text
+http://你的可访问地址:8787/auth/feishu/callback
+```
+
+这个地址里的域名和端口要与 `BASE_URL` 一致。配置后重启本系统，员工打开 `/submit` 会先跳转到飞书授权，授权完成后自动回到填写页，并自动带出当前填写人。
+
+如果暂时不填 `FEISHU_APP_ID` 和 `FEISHU_APP_SECRET`，系统会退回手动填写员工 ID 的模式。
+
+## Windows 任务计划
+
+本项目提供 Windows 任务计划脚本。任务每天触发，但发送前会读取 `data/workday-calendar.json`，只在国家法定工作日发送：
+
+- 工作日 18:00：日报填写提醒
+- 工作日 19:00：日报提交汇总
+
+这意味着：
+
+- 周一到周五如果是法定假期，不发送。
+- 周六、周日如果是调休补班，会发送。
+
+任务计划会直接运行 Python 模块发送飞书消息，不要求 Web 服务正在运行。但 `BASE_URL` 必须是员工能打开的地址。
+
+安装任务：
+
+```powershell
+Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
+.\scripts\install-windows-tasks.ps1
+```
+
+也可以直接双击：
+
+```text
+install-tasks.bat
+```
+
+如果你的 Python 不在默认路径，可以指定：
+
+```powershell
+.\scripts\install-windows-tasks.ps1 -PythonPath "C:\Path\To\python.exe"
+```
+
+手动测试提醒：
+
+```powershell
+python -m daily_report.scheduled reminder
+```
+
+手动测试汇总：
+
+```powershell
+python -m daily_report.scheduled summary
+```
+
+卸载任务：
+
+```powershell
+.\scripts\uninstall-windows-tasks.ps1
+```
+
+也可以直接双击：
+
+```text
+uninstall-tasks.bat
+```
+
+## 验证
+
+```bash
+python -m unittest discover -s tests
+python -m py_compile daily_report/config.py daily_report/db.py daily_report/report_service.py daily_report/robot_service.py daily_report/scheduled.py daily_report/web.py daily_report/workday.py

+# 飞书每日工作汇报系统实施计划
+
+> **给执行代理的要求：** 实施本计划时必须使用 `superpowers:subagent-driven-development`（推荐）或 `superpowers:executing-plans`。所有步骤使用复选框语法，便于逐项跟踪。
+
+**目标：** 构建第一版飞书日报 Web 应用，让员工提交每日报告，让管理者在一个页面浏览所有日报记录。
+
+**架构：** 使用 Python 标准库实现一个零第三方依赖的小型 Web 应用。后端使用 `http.server` 提供页面和 API，使用 `sqlite3` 保存员工与日报数据，使用 `urllib.request` 调用飞书机器人 Webhook。前端使用原生 HTML/CSS/JavaScript。
+
+**技术栈：** Python 标准库、`http.server`、`sqlite3`、`unittest`、原生 HTML/CSS/JavaScript、飞书自定义机器人 Webhook。
+
+---
+
+## 文件结构
+
+- `requirements.txt`：说明项目只使用 Python 标准库。
+- `.env.example`：环境变量示例。
+- `.gitignore`：忽略本地数据库、环境变量和缓存文件。
+- `data/employees.json`：第一版员工名单种子文件。
+- `daily_report/config.py`：读取环境变量和 `.env` 配置。
+- `daily_report/db.py`：SQLite 建表、员工导入和基础查询。
+- `daily_report/report_service.py`：日报校验、创建/更新、列表、未提交人员和 CSV 导出。
+- `daily_report/robot_service.py`：飞书机器人提醒/汇总消息体和 Webhook 发送。
+- `daily_report/web.py`：HTTP 页面路由、API 路由和静态文件服务。
+- `daily_report/static/styles.css`：提交页和管理页样式。
+- `daily_report/static/manager.js`：管理页筛选、复制汇总和数据加载逻辑。
+- `tests/test_report_service.py`：日报业务测试。
+- `tests/test_robot_service.py`：机器人消息体测试。
+- `tests/test_web.py`：页面和 API 冒烟测试。
+- `README.md`：中文使用说明。
+
+## 任务 1：项目骨架
+
+- [x] 创建 Python 包 `daily_report`。
+- [x] 创建 `requirements.txt`，说明无需第三方依赖。
+- [x] 创建 `.gitignore`。
+- [x] 创建 `.env.example`。
+- [x] 创建 `data/employees.json` 示例员工名单。
+- [x] 实现 `daily_report/config.py`，读取端口、基础 URL、数据库路径、员工名单路径和飞书 Webhook 配置。
+
+验证：
+
+```bash
+python -m py_compile daily_report/config.py
+```
+
+## 任务 2：数据层和日报服务
+
+- [x] 实现 `daily_report/db.py`。
+- [x] 创建 `employees` 表。
+- [x] 创建 `daily_reports` 表。
+- [x] 导入 `data/employees.json` 中的有效员工。
+- [x] 实现同一员工同一天唯一日报。
+- [x] 实现 `daily_report/report_service.py`。
+- [x] 校验必填字段：员工 ID、日期、今日完成、明日计划。
+- [x] 重复提交时更新当天已有日报。
+- [x] 计算已提交、未提交和应提交人数。
+- [x] 导出 CSV。
+- [x] 编写 `tests/test_report_service.py`。
+
+验证：
+
+```bash
+python -m unittest tests.test_report_service
+```
+
+## 任务 3：飞书机器人服务
+
+- [x] 实现 `daily_report/robot_service.py`。
+- [x] 生成“填写日报”提醒消息体。
+- [x] 生成“日报提交汇总”消息体。
+- [x] 支持调用飞书自定义机器人 Webhook。
+- [x] 编写 `tests/test_robot_service.py`。
+
+验证：
+
+```bash
+python -m unittest tests.test_robot_service
+```
+
+## 任务 4：页面和 API
+
+- [x] 实现 `daily_report/web.py`。
+- [x] 提供 `/submit` 员工日报提交页。
+- [x] 提供 `/manager` 管理者日报浏览页。
+- [x] 提供 `POST /api/reports` 创建或更新日报。
+- [x] 提供 `GET /api/reports?date=YYYY-MM-DD` 查询某日汇总。
+- [x] 提供 `GET /api/reports/export?date=YYYY-MM-DD` 导出 CSV。
+- [x] 提供 `POST /api/robot/send-reminder` 发送飞书提醒。
+- [x] 提供 `POST /api/robot/send-summary` 发送飞书汇总。
+- [x] 实现 `daily_report/static/styles.css`。
+- [x] 实现 `daily_report/static/manager.js`。
+- [x] 编写 `tests/test_web.py`。
+
+验证：
+
+```bash
+python -m unittest tests.test_web
+```
+
+## 任务 5：文档和手动验证
+
+- [x] 编写中文 `README.md`。
+- [x] 更新设计文档中的实际技术方案。
+- [x] 启动本地服务。
+- [x] 验证管理页可以访问。
+- [x] 验证日报提交 API 可以写入数据。
+- [x] 验证日报汇总 API 可以读取数据。
+
+启动：
+
+```bash
+python -m daily_report.web
+```
+
+访问：
+
+- 提交页：http://localhost:8787/submit
+- 管理页：http://localhost:8787/manager
+
+## 最终验证
+
+```bash
+python -m unittest discover -s tests
+python -m py_compile daily_report/config.py daily_report/db.py daily_report/report_service.py daily_report/robot_service.py daily_report/web.py
+```
+
+当前验证结果：
+
+- `python -m unittest discover -s tests`：8 个测试通过。
+- `python -m py_compile ...`：通过。
+- `http://localhost:8787/manager`：返回 200。

+# 飞书每日工作汇报系统设计
+
+## 目标
+
+建设一个轻量、实用的飞书每日工作汇报系统。员工每天通过飞书机器人提醒进入填写页面提交日报，管理者可以在一个内部浏览页面查看所有人的日报记录。
+
+第一版优先保证快速上线、流程顺畅、后续容易扩展。核心能力包括：每日提醒、员工填写、数据保存、管理者统一浏览、未提交统计和每日汇总。
+
+## 使用角色
+
+- 员工：每天提交一份工作日报。
+- 管理者：查看日报、检查未提交人员、复制或导出汇总。
+- 管理员：维护员工名单和飞书机器人配置。
+
+## 推荐方案
+
+采用“飞书机器人 + 小型 Web 应用”的方案。
+
+- 飞书机器人每天在指定群发送日报提醒。
+- 提醒消息里包含“填写日报”的按钮或链接。
+- 员工打开填写页面并提交日报。
+- 管理者打开浏览页面，在一个页面里查看所有记录。
+- 日报数据由应用保存，后续可以按需同步到飞书多维表格。
+
+这个方案比只使用多维表格更适合阅读和管理，也比完整飞书自建应用更容易启动。
+
+## 日报字段
+
+第一版采用标准四段式日报模板：
+
+- 员工姓名和飞书用户 ID
+- 汇报日期
+- 今日完成
+- 明日计划
+- 遇到的问题或阻塞
+- 需要协助的事项
+- 提交时间
+- 更新时间
+- 提交状态
+
+必填字段：
+
+- 员工身份
+- 汇报日期
+- 今日完成
+- 明日计划
+
+选填字段：
+
+- 遇到的问题或阻塞
+- 需要协助的事项
+
+如果员工当天重复提交，系统更新当天已有记录，不额外创建重复日报。
+
+## 飞书流程
+
+1. 到达配置的提醒时间，例如 18:00，机器人在工作汇报群发送日报提醒。
+2. 员工点击提醒消息中的“填写日报”。
+3. 系统打开日报填写页面，并默认选择当天日期。
+4. 员工填写四段式日报并提交。
+5. 后端校验并保存日报。
+6. 页面显示提交成功状态。
+7. 到达配置的汇总时间，例如 19:00，机器人在群里发送完成情况汇总：
+   - 应提交人数
+   - 已提交人数
+   - 未提交人员名单
+   - 管理者浏览页面链接
+
+第一版可以先使用带签名的链接或简单的员工选择方式识别员工。后续版本再接入飞书 OAuth，自动识别当前登录用户。
+
+## 管理者浏览页面
+
+管理者浏览页是日常查看日报的主工作台，打开后默认展示当天日报。
+
+筛选控件：
+
+- 日期选择
+- 员工筛选
+- 部门筛选，如果已配置部门
+- 关键词搜索
+- 只看未提交
+- 只看有问题或需要协助的日报
+
+主要内容：
+
+- 当前日期的提交统计
+- 按员工分组展示已提交日报
+- 未提交人员名单
+- 每条日报展示今日完成、明日计划、问题、协助需求和提交时间
+
+管理操作：
+
+- 复制今日汇总
+- 导出 CSV
+- 打开原始数据表
+
+页面应优先保证阅读体验，而不是做成纯表格。管理者应该能在一个页面里快速扫完当天所有日报。
+
+## 数据模型
+
+### employees
+
+- id
+- feishu_user_id
+- name
+- department
+- manager
+- active
+- created_at
+- updated_at
+
+### daily_reports
+
+- id
+- feishu_user_id
+- employee_name
+- report_date
+- today_done
+- tomorrow_plan
+- blockers
+- help_needed
+- submitted_at
+- updated_at
+
+唯一约束：
+
+- 同一个 `feishu_user_id` 在同一个 `report_date` 只能有一条日报
+
+## API 设计
+
+### 员工接口
+
+- `GET /submit`
+  - 展示日报填写页面。
+
+- `POST /api/reports`
+  - 创建或更新某员工某日期的日报。
+
+### 管理者接口
+
+- `GET /manager`
+  - 展示日报浏览页面。
+
+- `GET /api/reports?date=YYYY-MM-DD`
+  - 返回指定日期的已提交日报和未提交人员。
+
+- `GET /api/reports/export?date=YYYY-MM-DD`
+  - 导出指定日期的日报 CSV。
+
+### 机器人接口
+
+- `POST /api/robot/send-reminder`
+  - 向飞书群发送日报提醒。
+
+- `POST /api/robot/send-summary`
+  - 向飞书群发送日报完成情况汇总。
+
+这些接口第一版可以由本地定时任务或手动脚本调用。
+
+## 技术方案
+
+第一版实际技术栈：
+
+- 后端：Python 标准库 `http.server`
+- 前端：原生 HTML/CSS/JavaScript
+- 数据库：SQLite
+- 飞书集成：飞书自定义机器人 Webhook，用于发送提醒和汇总
+
+Python 标准库方案不依赖 npm 或第三方包，适合当前本地环境快速运行。SQLite 足够支撑第一版，并且部署简单。如果后续多人并发或权限要求增强，可以迁移到 PostgreSQL，用户流程不需要变化。
+
+## 错误处理
+
+- 必填字段缺失时，在表单内展示校验错误。
+- 当天重复提交时，更新已有日报。
+- 机器人发送失败时记录日志，并支持手动重试。
+- 管理页在指定日期没有日报时展示空状态。
+- 无法识别员工身份时，提交页要求员工从有效员工名单中选择姓名。
+
+## 安全设计
+
+第一版：
+
+- 使用难以猜测的提交链接，或仅在公司内部网络/内部成员范围内访问。
+- 管理页面只在内部使用。
+- 飞书 Webhook 密钥不写入源代码。
+
+后续版本：
+
+- 接入飞书 OAuth 自动识别员工身份。
+- 增加管理者权限控制。
+- 增加日报编辑审计日志。
+
+## 测试范围
+
+核心检查项：
+
+- 可以提交一份完整日报。
+- 缺少必填字段时拒绝提交。
+- 同一天重复提交会更新原记录。
+- 管理页能展示某日期的已提交和未提交人员。
+- 管理页能按员工和关键词筛选。
+- 可以导出 CSV。
+- 可以生成提醒消息和汇总消息。
+
+## 里程碑
+
+1. 搭建本地数据模型和日报提交流程。
+2. 搭建管理者浏览页面。
+3. 通过种子文件或简单配置维护员工名单。
+4. 接入飞书机器人提醒和汇总发送。
+5. 增加 CSV 导出和复制汇总功能。
+6. 可选：接入飞书 OAuth 和多维表格同步。
