# 生产任务 · 工艺步骤级派发 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 将生产任务派发粒度从「整条任务 + 单一负责人」改为「工艺步骤 + 多人负责人 + 计划开始时间」；「我的生产任务」按步骤负责人过滤；执行弹窗内仅可操作派给自己的步骤。

**Architecture:** 新增 `biz_production_task_step_assignee`（对齐 `biz_qc_task_assignee`）；步骤表增加 `planned_start_time`、`completed_by`；`PUT /production-tasks/{id}/steps/dispatch` 批量 sync 负责人；mine 鉴权从 `assert_task_assignee` 改为「任务级任一步 assignee OR 步骤级 assignee」+ 步骤写操作 `assert_step_assignee`；前端新增 `DispatchStepDialog.vue`，移除任务级负责人表单，隐藏任务转发/改派入口。

**Tech Stack:** MySQL 5.7 · FastAPI · SQLAlchemy · Pydantic v2 · Vue 3 · Element Plus · pnpm

**Design Spec:** `docs/superpowers/specs/2026-06-25-production-step-dispatch-design.md`

## Task 1: 数据库迁移

**Files:**
- Create: `docs/sql/migrations/2026-06-25-production-step-dispatch.sql`
- Create: `docs/sql/migrations/2026-06-25-production-step-dispatch-backfill.sql`
- Modify: `docs/sql/zkxw.sql`（`biz_production_task_step` 与新建表片段）

- [ ] **Step 1: 编写主 migration**

```sql
-- docs/sql/migrations/2026-06-25-production-step-dispatch.sql

ALTER TABLE `biz_production_task_step`
  ADD COLUMN `planned_start_time` datetime DEFAULT NULL COMMENT '计划开始时间' AFTER `step_status`;

ALTER TABLE `biz_production_task_step`
  ADD COLUMN `completed_by` varchar(64) DEFAULT NULL COMMENT '完成步骤的用户ID' AFTER `completed_time`;

CREATE TABLE IF NOT EXISTS `biz_production_task_step_assignee` (
  `id` varchar(64) NOT NULL COMMENT '主键',
  `step_id` varchar(64) NOT NULL COMMENT '生产任务步骤ID',
  `user_id` varchar(64) NOT NULL COMMENT '负责人用户ID',
  `tenant_no` varchar(64) NOT NULL DEFAULT 'zkxw' COMMENT '租户编号',
  `order_num` int DEFAULT 0 COMMENT '展示顺序',
  `remark` varchar(512) DEFAULT NULL COMMENT '备注',
  `create_by` varchar(64) DEFAULT NULL COMMENT '创建人id',
  `create_dept_id` varchar(64) NOT NULL DEFAULT '' COMMENT '创建人部门ID',
  `create_time` datetime NOT NULL COMMENT '创建时间',
  `update_by` varchar(64) DEFAULT NULL COMMENT '更新人id',
  `update_time` datetime NOT NULL COMMENT '更新时间',
  `del_flag` tinyint NOT NULL DEFAULT 0 COMMENT '删除标记',
  PRIMARY KEY (`id`),
  KEY `idx_step_assignee_step` (`step_id`),
  KEY `idx_step_assignee_user` (`user_id`, `tenant_no`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='生产任务步骤负责人';
```

- [ ] **Step 2: 编写可选 backfill（旧数据兼容）**

```sql
-- docs/sql/migrations/2026-06-25-production-step-dispatch-backfill.sql
-- 将仍有 task.current_assignee_user_id 且无步骤负责人的任务，回填到全部步骤

INSERT INTO biz_production_task_step_assignee (
  id, step_id, user_id, tenant_no, order_num,
  create_by, create_dept_id, create_time, update_by, update_time, del_flag
)
SELECT
  REPLACE(UUID(), '-', ''),
  s.id,
  t.current_assignee_user_id,
  s.tenant_no,
  0,
  t.create_by,
  IFNULL(t.create_dept_id, ''),
  NOW(),
  t.update_by,
  NOW(),
  0
FROM biz_production_task t
JOIN biz_production_task_step s ON s.task_id = t.id AND s.del_flag = 0
WHERE t.del_flag = 0
  AND t.current_assignee_user_id IS NOT NULL
  AND TRIM(t.current_assignee_user_id) <> ''
  AND NOT EXISTS (
    SELECT 1 FROM biz_production_task_step_assignee a
    WHERE a.step_id = s.id AND a.del_flag = 0
  );
```

- [ ] **Step 3: 在开发/测试库执行主 migration**

Run:

```bash
mysql -u ... -p ... zkxw < docs/sql/migrations/2026-06-25-production-step-dispatch.sql
```

Expected: 两列新增成功；`biz_production_task_step_assignee` 表存在。

- [ ] **Step 4: 同步 `docs/sql/zkxw.sql` 对应 DDL**

---

## Task 2: Backend 模型

**Files:**
- Modify: `backend/app/models/models.py`
- Modify: `backend/app/models/__init__.py`

- [ ] **Step 1: 扩展 `BizProductionTaskStep`**

在 `step_status` 后、`started_time` 前增加：

```python
planned_start_time = Column(DateTime, nullable=True, comment="计划开始时间")
```

在 `completed_time` 后增加：

```python
completed_by = Column(String(64), nullable=True, comment="完成步骤的用户ID")
```

- [ ] **Step 2: 新增 `BizProductionTaskStepAssignee`**

放在 `BizProductionTaskStep` 附近，字段对齐 migration SQL（参照 `BizQcTaskAssignee`）。

- [ ] **Step 3: 注册 export**

`backend/app/models/__init__.py`：

```python
from app.models.models import (
    # ...
    BizProductionTaskStepAssignee,
)
__all__ = [
    # ...
    "BizProductionTaskStepAssignee",
]
```

---

## Task 3: Backend Schema

**Files:**
- Modify: `backend/app/schemas/production_task.py`

- [ ] **Step 1: 创建任务 body 去掉 assignee 必填**

```python
class ProductionTaskCreate(BaseModel):
    model_config = ConfigDict(populate_by_name=True)
    work_order_id: str
    assignee_user_id: Optional[str] = Field(None, alias="assigneeUserId")  # deprecated，可选
    task_type: Optional[str] = 'cell_storage'
    task_name: Optional[str] = None
    route_id: Optional[str] = None
    description: Optional[str] = None
    remark: Optional[str] = None
```

- [ ] **Step 2: 新增步骤派发 body**

```python
class ProductionTaskStepDispatchItem(BaseModel):
    model_config = ConfigDict(populate_by_name=True)
    step_id: str = Field(..., alias="stepId")
    assignee_user_ids: List[str] = Field(..., alias="assigneeUserIds", min_length=1)
    planned_start_time: Optional[datetime] = Field(None, alias="plannedStartTime")


class ProductionTaskStepDispatchBody(BaseModel):
    model_config = ConfigDict(populate_by_name=True)
    steps: List[ProductionTaskStepDispatchItem] = Field(..., min_length=1)
```

---

## Task 4: 步骤负责人 CRUD 模块

**Files:**
- Create: `backend/app/crud/production_task_step_assignee.py`

- [ ] **Step 1: 创建模块（复制 QC 模式并改表名）**

```python
"""生产任务步骤负责人 CRUD"""

                "userNo": (u.user_no or "") if u else "",
            }
            for a, u in pairs
        ]


def user_is_step_assignee(
    db: Session, step_id: str, user_id: str, tenant_no: str

        .filter(
            BizProductionTaskStepAssignee.step_id == step_id,
            BizProductionTaskStepAssignee.user_id == uid,
            BizProductionTaskStepAssignee.tenant_no == tenant_no,
            BizProductionTaskStepAssignee.del_flag == 0,

    uid = (user_id or "").strip()
    if not uid:
        return False
    return (
        db.query(BizProductionTaskStepAssignee.id)
        .join(
            BizProductionTaskStep,
            BizProductionTaskStep.id == BizProductionTaskStepAssignee.step_id,
        )

        )
        .first()
        is not None
    )
```

- [ ] **Step 2: 本地 import  smoke test**

Run:

```bash
cd backend && source venv/bin/activate
python -c "from app.crud import production_task_step_assignee; print('ok')"
```

Expected: `ok`

---

## Task 5: production_task.py — 步骤 dict、派发、mine 过滤

**Files:**
- Modify: `backend/app/crud/production_task.py`

- [ ] **Step 1: 扩展 `_step_to_dict`**

```python
def _step_to_dict(s: BizProductionTaskStep) -> Dict[str, Any]:
    return {
        # ... existing fields ...
        "stepStatus": s.step_status or "dzx",
        "plannedStartTime": _fmt_dt(getattr(s, "planned_start_time", None)),
        "startedTime": _fmt_dt(s.started_time),
        "completedTime": _fmt_dt(s.completed_time),
        "completedBy": getattr(s, "completed_by", None) or "",
        "completedByName": "",
        "assigneeUserIds": [],
        "assigneeNames": [],
        "assignees": [],
        "remark": s.remark or "",
    }
```

- [ ] **Step 2: `create_production_task` 去掉 assignee 必填**

删除或注释：

```python
assignee_raw = (data.get("assignee_user_id") or data.get("assigneeUserId") or "").strip()
assignee_user_id = _validate_assignee_user_id(db, assignee_raw, tenant_no)
```

改为：

```python
assignee_raw = (data.get("assignee_user_id") or data.get("assigneeUserId") or "").strip()
assignee_user_id = assignee_raw.strip() or None
if assignee_raw.strip():
    assignee_user_id = _validate_assignee_user_id(db, assignee_raw, tenant_no)
```

创建任务时：

```python
current_assignee_user_id=assignee_user_id,  # 可为 NULL
```

- [ ] **Step 3: 新增 `dispatch_task_steps`**

```python
def dispatch_task_steps(
    db: Session,
    task_id: str,
    *,
    tenant_no: str,
    steps_payload: List[Dict[str, Any]],
    operator_id: Optional[str] = None,
    create_dept_id: str = "",
) -> Dict[str, Any]:
    from app.crud import production_task_step_assignee as step_assignee_svc

    task = get_production_task_row(db, task_id, tenant_no)
    if not task:
        raise ValueError("任务不存在")
    if not steps_payload:
        raise ValueError("请至少指定一个步骤的负责人")

    step_rows = {
        s.id: s
        for s in db.query(BizProductionTaskStep).filter(
            BizProductionTaskStep.task_id == task_id,
            BizProductionTaskStep.tenant_no == tenant_no,
            BizProductionTaskStep.del_flag == 0,
        ).all()
    }

    for item in steps_payload:
        sid = (item.get("step_id") or item.get("stepId") or "").strip()
        if sid not in step_rows:
            raise ValueError(f"步骤不存在或不属于该任务: {sid}")
        user_ids = item.get("assignee_user_ids") or item.get("assigneeUserIds") or []
        step_assignee_svc.sync_assignees_for_step(
            db, sid, user_ids,
            tenant_no=tenant_no,
            operator_id=operator_id,
            create_dept_id=create_dept_id,
        )
        step = step_rows[sid]
        pst = item.get("planned_start_time") or item.get("plannedStartTime")
        if pst is None and "plannedStartTime" in item and item.get("plannedStartTime") is None:
            step.planned_start_time = None
        elif pst:
            from dateutil.parser import parse as _parse_dt
            step.planned_start_time = _parse_dt(str(pst)) if not isinstance(pst, datetime) else pst
        step.update_by = operator_id
        step.update_time = datetime.now()
        db.add(step)

    db.flush()
    detail = get_production_task_detail(db, task_id, tenant_no)
    if not detail:
        raise ValueError("任务不存在")
    return detail
```

- [ ] **Step 4: 改造 `list_production_tasks` mine 过滤**

新增参数 `step_assignee_user_id: Optional[str] = None`。

在 `current_assignee_user_id` 过滤块 **之后** 增加：

```python
sa_uid = (step_assignee_user_id or "").strip()
if sa_uid:
    step_task_ids = (
        db.query(BizProductionTaskStep.task_id)
        .join(
            BizProductionTaskStepAssignee,
            BizProductionTaskStepAssignee.step_id == BizProductionTaskStep.id,
        )
        .filter(
            BizProductionTaskStepAssignee.user_id == sa_uid,
            BizProductionTaskStepAssignee.tenant_no == tenant_no,
            BizProductionTaskStepAssignee.del_flag == 0,
            BizProductionTaskStep.del_flag == 0,
            BizProductionTask.del_flag == 0,
        )
        .distinct()
        .subquery()
    )
    q = q.filter(
        or_(
            BizProductionTask.id.in_(step_task_ids),
            BizProductionTask.current_assignee_user_id == sa_uid,  # 旧数据 fallback
        )
    )
```

- [ ] **Step 5: 改造 `list_mine_production_tasks`**

`scope=current` 时调用：

```python
return list_production_tasks(
    # ...
    step_assignee_user_id=uid,
    current_assignee_user_id=None,  # 不再仅用 task 级
    # ...
)
```

保留 `current_assignee_user_id=uid` 作为 OR 条件已在 Step 4 合并；或直接只传 `step_assignee_user_id=uid` 并在 SQL 内 OR task assignee fallback。

- [ ] **Step 6: 新增 assert 函数**

```python
def assert_task_step_assignee_or_legacy(
    db: Session, task_id: str, user_id: str, tenant_no: str
) -> BizProductionTask:
    from app.crud import production_task_step_assignee as step_assignee_svc

    task = get_production_task_row(db, task_id, tenant_no)
    if not task:
        raise ValueError("任务不存在")
    if step_assignee_svc.user_is_any_step_assignee_of_task(db, task_id, user_id, tenant_no):
        return task
    if (task.current_assignee_user_id or "") == (user_id or ""):
        return task
    raise PermissionError("非任务步骤负责人，无权操作")


def assert_step_assignee_for_write(
    db: Session,
    step_id: str,
    user_id: str,
    tenant_no: str,
    *,
    manage: bool = False,
) -> BizProductionTaskStep:
    if manage:
        step = db.query(BizProductionTaskStep).filter(
            BizProductionTaskStep.id == step_id,
            BizProductionTaskStep.tenant_no == tenant_no,
            BizProductionTaskStep.del_flag == 0,
        ).first()
        if not step:
            raise ValueError("步骤不存在")
        return step
    from app.crud import production_task_step_assignee as step_assignee_svc
    step = db.query(BizProductionTaskStep).filter(
        BizProductionTaskStep.id == step_id,
        BizProductionTaskStep.tenant_no == tenant_no,
        BizProductionTaskStep.del_flag == 0,
    ).first()
    if not step:
        raise ValueError("步骤不存在")
    if not step_assignee_svc.user_is_step_assignee(db, step_id, user_id, tenant_no):
        raise PermissionError("非当前步骤负责人，无权操作")
    return step
```

- [ ] **Step 7: `update_task_step` 写 `completed_by`**

当 `data.get("step_status") == "ywc"` 且 `user_id` 存在：

```python
step.completed_by = user_id
```

- [ ] **Step 8: `get_production_task_detail` enrich 步骤 assignee**

加载 steps 后调用：

```python
from app.crud.production_task_step_assignee import enrich_step_assignees
enrich_step_assignees(db, steps, tenant_no=tenant_no)
# 可选：_enrich_completed_by_names
```

## Task 6: API 路由与鉴权

**Files:**
- Modify: `backend/app/api/production.py`

- [ ] **Step 1: 改造 `_assert_production_task_write_access`**

```python
def _assert_production_task_write_access(
    db: Session,
    user: dict,
    task_id: str,
    tenant_no: str,
    operate_scope: Optional[str],
) -> None:
    scope = (operate_scope or "manage").strip().lower()
    user_id = _get_current_user_id(user)
    role = user.get("role")
    codes = get_user_menu_codes(db, user_id) if role != SUPER_ADMIN_ROLE else set()
    if scope == "mine":
        if role != SUPER_ADMIN_ROLE and "production:my-task:list" not in codes:
            raise PermissionError("无菜单访问权限")
        production_task_svc.assert_task_step_assignee_or_legacy(
            db, task_id, user_id, tenant_no
        )
    elif role != SUPER_ADMIN_ROLE and "production:work-order:list" not in codes:
        raise PermissionError("无菜单访问权限")
```

- [ ] **Step 2: 新增步骤写鉴权 helper**

```python
def _assert_production_task_step_write_access(
    db: Session,
    user: dict,
    step_id: str,
    tenant_no: str,
    operate_scope: Optional[str],
) -> None:
    scope = (operate_scope or "manage").strip().lower()
    user_id = _get_current_user_id(user)
    role = user.get("role")
    codes = get_user_menu_codes(db, user_id) if role != SUPER_ADMIN_ROLE else set()
    manage = scope != "mine"
    if not manage:
        if role != SUPER_ADMIN_ROLE and "production:my-task:list" not in codes:
            raise PermissionError("无菜单访问权限")
    elif role != SUPER_ADMIN_ROLE and "production:work-order:list" not in codes:
        raise PermissionError("无菜单访问权限")
    production_task_svc.assert_step_assignee_for_write(
        db, step_id, user_id, tenant_no, manage=manage
    )
```

- [ ] **Step 3: 注册 `PUT /production-tasks/{task_id}/steps/dispatch`**

```python
@router.put("/production-tasks/{task_id}/steps/dispatch")
async def dispatch_production_task_steps_api(
    task_id: str,
    body: ProductionTaskStepDispatchBody,
    user: dict = Depends(require_menu_code("production:work-order:list")),
    db: Session = Depends(get_db),
):
    try:
        tenant_no = _get_tenant_no(db, user)
        payload = [
            {
                "step_id": it.step_id,
                "assignee_user_ids": it.assignee_user_ids,
                "planned_start_time": it.planned_start_time,
            }
            for it in body.steps
        ]
        detail = production_task_svc.dispatch_task_steps(
            db,
            task_id,
            tenant_no=tenant_no,
            steps_payload=payload,
            operator_id=user.get("user_id"),
            create_dept_id=user.get("dept_id", ""),
        )
        db.commit()
        return success_response(detail, message="步骤派发成功")
    except ValueError as e:
        db.rollback()
        return error_response(400, str(e))
```

- [ ] **Step 4: 步骤写接口增加 step 级鉴权**

在以下 handler **内** `_assert_production_task_write_access` 之后追加 `_assert_production_task_step_write_access`：

- `update_production_task_step`
- `replace_task_step_reagents`
- `replace_task_step_consumables`
- `replace_task_step_configured_reagents`
- `replace_task_step_data_collections`
- `replace_task_step_outputs`
- `delete_production_task_step`
- `copy_production_task_step`

示例（`update_production_task_step`）：

```python
_assert_production_task_write_access(db, user, task_id, tenant_no, operateScope)
_assert_production_task_step_write_access(db, user, step_id, tenant_no, operateScope)
```

任务级 inputs/outputs/attachments/status 仍只用 task 级 assert（D10：任一步 assignee 即可）。

- [ ] **Step 5: Swagger 手动验证**

Run backend，在 `/docs` 测试：

1. `PUT .../steps/dispatch` 返回 steps 含 `assigneeUserIds`
2. `GET .../production-tasks/mine?scope=current` 仅 assignee 可见

---

## Task 7: Frontend API

**Files:**
- Modify: `web-admin/src/api/production-task.ts`

- [ ] **Step 1: 新增 dispatch API**

```typescript
export function fetchDispatchProductionTaskSteps(
  taskId: string,
  data: {
    steps: Array<{
      stepId: string
      assigneeUserIds: string[]
      plannedStartTime?: string | null
    }>
  }
) {
  return request.put<any>({
    url: `/web/admin/production-tasks/${taskId}/steps/dispatch`,
    data
  })
}
```

- [ ] **Step 2: 确认 create 不再传 assigneeUserId**

`DispatchTaskDialog.vue` 将在 Task 9 移除该字段。

---

## Task 8: DispatchStepDialog.vue（新建）

**Files:**
- Create: `web-admin/src/views/production/production-work-order/DispatchStepDialog.vue`

- [ ] **Step 1: 实现弹窗骨架**

要点：

- Props: `visible`, `taskId`, `taskName?`
- 打开时 `fetchProductionTaskDetail(taskId)` 加载 `steps`
- 表格列：序号、`processName`、负责人多选（remote `fetchUserList`）、计划开始时间
- 本地 state：`rows: { stepId, processName, assigneeUserIds, plannedStartTime, userOptions }[]`
- 提交：过滤 `assigneeUserIds.length >= 1` 的行，调用 `fetchDispatchProductionTaskSteps`
- 校验：至少 1 行有负责人
- UI：`dialog-form-layout`、`label-position="top"`、footer Close/Check 图标

- [ ] **Step 2: 回显已有 assignee**

detail.steps 中若已有 `assigneeUserIds` / `plannedStartTime`，填入表单。

---

## Task 9: DispatchTaskDialog.vue 改造

**Files:**
- Modify: `web-admin/src/views/production/production-work-order/DispatchTaskDialog.vue`

- [ ] **Step 1: 移除任务级负责人**

删除表单项 `assigneeUserId`、`rules.assigneeUserId`、`form.assigneeUserId` 及 create payload 中的 `assigneeUserId`。

- [ ] **Step 2: B 入口 — 创建后打开步骤派发**

在 `handleCreateTask` 成功、`enterEditPhase` 之后：

```typescript
emit('open-step-dispatch', { taskId, taskName: form.taskName })
```

或由父组件监听 `@success` 并根据是否选了 `routeId` 打开 `DispatchStepDialog`。

推荐：Dialog 内 `emit('needStepDispatch', taskId)`，父组件 `WorkOrderTaskSubList` / `index.vue` 统一挂载 `DispatchStepDialog`。

- [ ] **Step 3: 若选了 route 且步骤已克隆**

创建成功 + `expectSteps` 为 true 时，关闭编辑阶段或保留编辑的同时弹出步骤派发（产品：B 入口）。

---

## Task 10: WorkOrderTaskSubList.vue 改造

**Files:**
- Modify: `web-admin/src/views/production/production-work-order/WorkOrderTaskSubList.vue`

- [ ] **Step 1: 挂载 DispatchStepDialog**

```vue
<DispatchStepDialog
  v-model:visible="stepDispatchVisible"
  :task-id="stepDispatchTaskId"
  :task-name="stepDispatchTaskName"
  @success="handleTaskMutationSuccess"
/>
```

- [ ] **Step 2: 管理视角增加「步骤派发」按钮**

在 `!isMineMode` 且任务非 `yzf` 时显示；文案：无 assignee 时「步骤派发」，否则「调整派发」。

判断：任一步 `assigneeUserIds?.length` 或后端返回 `hasStepDispatch`。

- [ ] **Step 3: 隐藏 deprecated 转发/改派**

删除或 `v-if="false"`：

- 下拉「转发任务」「改派负责人」
- `ForwardTaskDialog` 引用可保留文件但不挂载

- [ ] **Step 4: 任务卡片 meta 展示步骤负责人摘要**

在任务名下方增加 muted 文本，例如：`步骤负责人：张三、李四（细胞培养 09:00）` — 取前 2 步或折叠展示。

---

## Task 11: 执行弹窗 — 步骤权限与只读

**Files:**
- Modify: `web-admin/src/views/production/production-work-order/useTaskStepEditor.ts`
- Modify: `web-admin/src/views/production/production-work-order/TaskExecutionDialog.vue`
- Modify: `web-admin/src/views/production/production-work-order/StepDetailPanel.vue`

- [ ] **Step 1: useTaskStepEditor 增加 canEditStep**

```typescript
import { useUserStore } from '@/store/modules/user'

const userStore = useUserStore()

function canEditStep(step: Record<string, any> | null | undefined): boolean {
  if (!step) return false
  if (operateScope.value !== 'mine') return true
  const uid = userStore.info?.id || userStore.userId || ''
  const ids: string[] = step.assigneeUserIds || []
  return ids.includes(uid)
}

function visibleStepsForMine(steps: Record<string, any>[]) {
  if (operateScope.value !== 'mine') return steps
  return steps.filter((s) => (s.assigneeUserIds || []).length > 0)
}
```

导出 `canEditStep`、`visibleStepsForMine`（或 computed `displayStepList`）。

- [ ] **Step 2: TaskExecutionDialog 步骤列表**

- mine：`v-for="element in editor.displayStepList"`（仅已派步骤）
- 对 `!canEditStep(element)` 的步骤加 class `is-readonly`（降低 opacity，禁用 drag）
- 任务级「转发任务」按钮移除

- [ ] **Step 3: StepDetailPanel 按钮**

```vue
<el-button
  v-if="editor.mode.value === 'execution' && editor.canEditStep(editor.selectedStep.value)"
  ...
/>
```

保存 / 开始 / 完成均加 `canEditStep` 条件；只读时仅展示内容。

- [ ] **Step 4: 步骤写操作前端 guard（可选双保险）**

`handleStartStep` / `handleCompleteStep` 开头：

```typescript
if (!canEditStep(step)) {
  ElMessage.warning('非当前步骤负责人，无法操作')
  return
}
```

## Task 12: 字段一致性与图谱

**Files:**
- Run: `backend/scripts/check_field_consistency.py`（若涉及 CRUD 字段变更）
- Run: `./scripts/update-graph.sh backend frontend`

- [ ] **Step 1: 字段一致性检查**

Run:

```bash
cd backend && source venv/bin/activate
python scripts/check_field_consistency.py
```

Expected: 无 production_task step 相关新增不一致；若有 `_row_to_dict` 变更则修复 schema/前端。

- [ ] **Step 2: 更新知识图谱**

Run:

```bash
./scripts/update-graph.sh backend
./scripts/update-graph.sh frontend
```

---

## Task 13: 手工测试清单

- [ ] **B 入口**：生产工单 → 派发任务 → 选工艺路线 → 创建 → 步骤派发 → 用户 A/B 在「我的生产任务」见工单，执行时仅各自步骤可操作，其他只读。

- [ ] **A 入口**：无路线创建 → 手工加 3 步 → 步骤派发 → 同上。

- [ ] **一步多人**：A、B 同为步骤 1 负责人；A 完成步骤 1 后 B 见只读已完成。

- [ ] **同人多步**：步骤 1、2 均派给 A；A 两步均可操作。

- [ ] **计划开始时间**：卡片/派发弹窗展示；未到时间仍可执行。

- [ ] **未派步骤**：mine 执行弹窗不显示该步；manage 可见可操作。

- [ ] **改派**：manage 调整派发后，旧 assignee mine 列表消失（若无其他步骤），新 assignee 出现。

- [ ] **旧数据 backfill**（若执行 backfill SQL）：原 task assignee 仍能在 mine 看到任务。

- [ ] **回归**：任务输入/产出/完成整单、派发质检工单链路不受影响。

## Spec Coverage Self-Review

| Spec 要求 | 对应 Task |
|-----------|-----------|
| D1 工单+任务列表 | Task 5 mine 过滤不变外层结构 |
| D2 其他步骤只读 | Task 11 |
| D3 一步多人任一完成 | Task 5 Step 7 completed_by |
| D4 计划开始时间不阻断 | Task 8/11 无前端时间校验 |
| D5 A+B 双入口 | Task 8/9/10 |
| D6 未派步骤仅 manage | Task 11 visibleStepsForMine |
| D7 方案 1 数据模型 | Task 1–4 |
| D8 任务 assignee 非必填 | Task 3/5 |
| D9 转发 deprecated | Task 10 |
| D10 任务 I/O 任一步 assignee | Task 6 task 级 assert |
| D11 mine 不可改派 | Task 6 dispatch 仅 work-order 权限 |

无 TBD 占位；类型命名 `assigneeUserIds` / `plannedStartTime` 前后端一致。

## 建议实施顺序

```
Task 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 10 → 11 → 12 → 13
         └─ backend 可联调 ─┘       └─ frontend ─────────────┘
```

Backend Task 1–6 完成后即可用 Swagger 验证 mine 过滤与 dispatch；Frontend Task 7–11 依赖后端 API。
