+# OA 表单设计 · 离职套件（Resignation Kit）设计文档
+
+**日期**: 2026-07-30  
+**状态**: 已实现  
+**范围**: `web-admin` 用户管理补齐最后工作日；审批套件 Tab 离职套件；发起默认入职日期；`backend` 审批通过后回写发起人 `last_work_day`  
+**界面模式**: 对齐请假/转正套件；视觉 Fresh Mint  
+**前置**:  
+- `docs/superpowers/specs/2026-07-30-oa-leave-kit-design.md`  
+- `docs/superpowers/specs/2026-07-30-oa-confirmation-kit-design.md`（回写模式）  
+
+---
+
+## 1. 背景与目标
+
+套件 Tab 增加 **离职套件**：采集入职日期、最后工作日、离职原因及备注；审批通过后将最后工作日回写发起人用户主数据。
+
+### 1.1 目标
+
+- `sys_user` 增补 **最后工作日**；用户管理新增/编辑/详情可维护。  
+- 拖入离职套件得到 4 个子字段。  
+- 发起时入职日期默认申请人（可改）。  
+- 离职原因内置 5 项，设计器可维护 options。  
+- 审批 **全部通过** 后仅回写发起人 `last_work_day`。  
+
+### 1.2 非目标（首期）
+
+- 通过后自动停用账号。  
+- 入职日期、离职原因、备注回写用户表。  
+- 「最后工作日 ≥ 入职日期」交叉校验。  
+- 代他人离职并回写他人主数据。  
+
+---
+
+## 2. 产品决策（已确认）
+
+| 项 | 决策 |
+|----|------|
+| 实现方案 | 套件容器 + 子字段拼装 |
+| 容器类型 | `resignationKit` |
+| 回写时机 | 审批全部通过 |
+| 回写对象 | 始终发起人 |
+| 回写字段 | 仅最后工作日 |
+| 账号状态 | 不动 |
+| 用户管理 | 最后工作日可新增/编辑/详情 |
+| 入职日期 | 默认申请人，可改，不回写 |
+| 最后工作日 | 默认必填（设计器可改）；手填 |
+| 交叉校验 | 首期不做 |
+| 原因/备注 | 仅审批单 |
+
+---
+
+## 3. 信息模型
+
+### 3.1 心智模型
+
+```
+┌─ 离职套件（resignationKit）──────────────────────────┐
+│  · datePicker   入职日期        ← userInfo.hireDate    │
+│  · datePicker   最后工作日      ← 手填；通过后回写     │
+│  · select       离职原因        ← 5 默认项，可配置     │
+│  · textarea     离职原因备注                           │
+└──────────────────────────────────────────────────────┘
+```
+
+运行时不渲染套件边框/标题。
+
+### 3.2 子字段
+
+| 语义 key | title | type | 必填默认 | 回写 |
+|----------|-------|------|----------|------|
+| `hireDate` | 入职日期 | datePicker 仅日期 | 是 | ✗ |
+| `lastWorkDay` | 最后工作日 | datePicker 仅日期 | 是 | ✓ → `last_work_day` |
+| `resignReason` | 离职原因 | select | 是 | ✗ |
+| `resignRemark` | 离职原因备注 | textarea | 否 | ✗ |
+
+离职原因默认 options：
+
+- 家庭原因  
+- 个人原因  
+- 发展原因  
+- 合同到期不续签  
+- 其他  
+
+语义识别：`props._fc_kit_field`；容器 props 可挂各 `*Field` id。

+  ]
+}
+```
+
+---
+
+## 4. 用户主数据
+
+### 4.1 增列
+
+```sql
+ALTER TABLE `sys_user`
+  ADD COLUMN `last_work_day` date DEFAULT NULL COMMENT '最后工作日' AFTER `probation_months`;
+```
+
+（若库中无 `probation_months`，则 AFTER `hire_date` 或 `phone_no`。）
+
+同步：`SysUser`、`_row_to_dict`（`lastWorkDay`）、Create/Update Body、用户管理表单与详情、`userInfo` 可选带出 `lastWorkDay`（套件默认不依赖此项）。
+
+---
+
+## 5. 运行时
+
+### 5.1 发起默认
+
+仅对空的入职日期写入 `userInfo.hireDate`。其余字段不默认。
+
+### 5.2 提交 / 发布
+
+- 可见必填按 FormCreate 校验。  
+- `LAYOUT_TYPES` 纳入 `resignationKit`。  
+- 打印 unwrap 同其它套件。  
+
+### 5.3 通过后回写
+
+挂在实例 `status = completed` 后（可与转正 sync 并列调用）：
+
+`apply_resignation_kit_user_sync(db, inst)`
+
+- 扫描 `resignationKit` → 取 `lastWorkDay`  
+- 有合法 `YYYY-MM-DD` 则更新发起人 `last_work_day`  
+- 空 / 非法：跳过 + log；异常不回滚通过状态  
+
+---
+
+## 6. 建议文件落点
+
+| 区域 | 路径 |
+|------|------|
+| SQL | `docs/sql/sys_user_last_work_day.sql` |
+| 模型/CRUD/API/用户管理 | 同转正补字段路径 |
+| 容器 | `OaResignationKit.vue` |
+| DragRule / 注册 | `oa-resignation-kit-rule.ts`、`oa-form-create-resignation-kit.ts` |
+| 默认值 | `oa-resignation-kit-runtime.ts` |
+| 回写 | `oa_resignation_kit_sync.py` + `oa_engine` completed 钩子 |
+| 发布/打印 | `oa_publish.py`、`oa-approval-print.ts` |
+| 设计器拖入刷新 | `oa-fc-host/App.vue`（纳入 kit 名列表） |
+
+---
+
+## 7. 验收标准
+
+1. 用户管理可维护最后工作日。  
+2. 套件 Tab 可拖「离职」；原因默认 5 项且设计器可改。  
+3. 发起：入职日期自动带出可改；最后工作日/原因/备注按规则校验。  
+4. 通过前主数据最后工作日不变；通过后写入发起人；空不写。  
+5. 入职日期、原因、备注不回写；账号状态不变。  
+
+---
+
+## 8. 开放细节（不阻塞）
+
+- `userInfo` 是否带出 `lastWorkDay`：可选，套件不依赖。  
+- 与转正 sync 共用一个 hook 文件或并列两个函数：实现任选，逻辑分离即可。
