+# 运输计划合同完善 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:** 新增独立菜单页「运输计划合同完善」：只列出未作废且仍缺合同的计划，支持行内展开、分侧多选并各自保存已有 CRM 合同，并显示侧栏待完善角标。
+
+**Architecture:** 后端在 `pl_plan_service` 提供缺口判定与 SQL 过滤，暴露 `GET /transport/plan/contract-gaps` 与 `PUT /transport/plan/{id}/contracts/{side}`；角标复用 `pl_menu_badge_service`。前端新页 `views/pl/plan-contract/index.vue` 用 `el-table` 展开行 + 复用 `PlPlanContractMultiSelect`/`ContractSelector`，不打开合同表单。
+
+**Tech Stack:** FastAPI + SQLAlchemy + MySQL；Vue 3 + Element Plus；现有 `planApi` / 菜单角标
+
+**Spec:** `docs/superpowers/specs/2026-08-20-pl-plan-contract-complete-design.md`  
+**Demo:** `docs/fresh-mint-pl-plan-contract-complete-demo.html`（方案 B）

+git commit -m "feat(pl): add plan contract gap side computation helpers"
+```
+
+---
+
+### Task 2: SQL EXISTS 过滤器 + Schema
+
+**Files:**
+- Modify: `backend/app/services/pl_plan_contract_gap.py`
+- Modify: `backend/app/schemas/pl/plan.py`
+- Modify: `backend/tests/test_pl_plan_contract_gap.py`
+
+- [ ] **Step 1: 增加 EXISTS 过滤器（供列表 `query.filter(...)`）**
+
+在 `pl_plan_contract_gap.py` 增加：
+
+```python
+from sqlalchemy import and_, exists, func, or_, select
+from sqlalchemy.orm import Session
+from app.models.pl_models import PlPlan, PlPlanContract
+from app.services.pl_internal_customer import INTERNAL_CUSTOMER_NAMES
+from app.services.pl_plan_service import (
+    PLAN_CONTRACT_SIDE_DEMANDER,
+    PLAN_CONTRACT_SIDE_SUPPLIER,
+)
+
+def _side_has_contract_exists(plan_id_col, side: str):
+    return exists().where(
+        and_(
+            PlPlanContract.plan_id == plan_id_col,
+            PlPlanContract.side == side,
+            PlPlanContract.del_flag == 0,
+        )
+    )
+
+def plan_has_contract_gap_exists():
+    """未作废计划中，任一侧（非内置且无合同）构成缺口。"""
+    supplier_gap = and_(
+        ~PlPlan.supplier_name.in_(tuple(INTERNAL_CUSTOMER_NAMES)),
+        ~_side_has_contract_exists(PlPlan.id, PLAN_CONTRACT_SIDE_SUPPLIER),
+    )
+    demander_gap = and_(
+        ~PlPlan.customer_name.in_(tuple(INTERNAL_CUSTOMER_NAMES)),
+        ~_side_has_contract_exists(PlPlan.id, PLAN_CONTRACT_SIDE_DEMANDER),
+    )
+    return or_(supplier_gap, demander_gap)
+```
+
+注意：`supplier_name` / `customer_name` 为 NULL 时，`NOT IN (内置)` 在 SQL 中为 UNKNOWN，不会命中缺口——与「无客户名」极少见一致；若需把空名当缺口，改为 `(name IS NULL OR name NOT IN (...))`。**本计划采用：空名视为非内置 → 缺合同**，实现时写成：
+
+```python
+supplier_not_internal = or_(
+    PlPlan.supplier_name.is_(None),
+    PlPlan.supplier_name == "",
+    ~PlPlan.supplier_name.in_(tuple(INTERNAL_CUSTOMER_NAMES)),
+)
+```
+
+- [ ] **Step 2: 单测编译 SQL**
+
+```python
+def test_plan_has_contract_gap_exists_mentions_contract_and_internal_names():
+    from sqlalchemy.dialects import mysql
+    from app.services.pl_plan_contract_gap import plan_has_contract_gap_exists
+    clause = plan_has_contract_gap_exists()
+    sql = str(clause.compile(dialect=mysql.dialect(), compile_kwargs={"literal_binds": True})).lower()
+    assert "pl_plan_contract" in sql
+    assert "supplier" in sql
+    assert "demander" in sql
+    assert "安庆市山峡化工有限公司" in sql or "shanxia" in sql  # 名称应被绑定进 SQL
+```
+
+（若 dialect 把中文绑成参数导致字面量不出现，改为断言 `pl_plan_contract` + `side` 即可。）
+
+- [ ] **Step 3: Schema**
+
+在 `backend/app/schemas/pl/plan.py` 增加（camelCase alias，与现有一致）：
+
+```python
+class PlanSideContractsUpdateBody(BaseModel):
+    contracts: list[PlanContractLink] = Field(default_factory=list)
+    model_config = {"populate_by_name": True}
+
+
+class PlanContractGapRead(BaseModel):
+    id: str
+    plan_no: str = Field(..., alias="planNo")
+    plan_date: Optional[date] = Field(None, alias="planDate")
+    follow_status: str = Field(..., alias="followStatus")
+    supplier_id: Optional[str] = Field(None, alias="supplierId")
+    supplier_name: Optional[str] = Field(None, alias="supplierName")
+    customer_id: Optional[str] = Field(None, alias="customerId")
+    customer_name: Optional[str] = Field(None, alias="customerName")
+    gap_sides: list[str] = Field(default_factory=list, alias="gapSides")
+    supplier_contract_exempt: bool = Field(..., alias="supplierContractExempt")
+    demander_contract_exempt: bool = Field(..., alias="demanderContractExempt")
+    supplier_contracts: list[PlanContractLink] = Field(default_factory=list, alias="supplierContracts")
+    demander_contracts: list[PlanContractLink] = Field(default_factory=list, alias="demanderContracts")
+    model_config = {"populate_by_name": True, "from_attributes": True}
+
+
+class PlanContractGapListResponse(BaseModel):
+    total: int
+    list: list[PlanContractGapRead]
+```
+
+并从 `app.schemas.pl` / `plan.py` 导出（若 `__init__.py` 有显式导出则补上）。
+
+- [ ] **Step 4: 提交**
+
+```bash
+git add backend/app/services/pl_plan_contract_gap.py backend/app/schemas/pl/plan.py backend/tests/test_pl_plan_contract_gap.py
+git commit -m "feat(pl): add contract-gap SQL filter and response schemas"
+```
+

+
+### Task 3: 列表 API `GET /contract-gaps`
+
+**Files:**
+- Modify: `backend/app/services/pl_plan_contract_gap.py`（或 `pl_plan_service.py`）增加 `list_plan_contract_gaps(...)`
+- Modify: `backend/app/api/pl/plan.py`
+
+- [ ] **Step 1: 服务函数签名（实现要点）**
+
+```python
+def list_plan_contract_gaps(
+    db: Session,
+    *,
+    tenant_no: str,
+    user,
+    page: int = 1,
+    page_size: int = 20,
+    plan_no: Optional[str] = None,
+    gap_type: Optional[str] = None,  # supplier | demander | both | None
+    customer_keyword: Optional[str] = None,
+    plan_date_from: Optional[date] = None,
+    plan_date_to: Optional[date] = None,
+    q: Optional[str] = None,
+) -> tuple[int, list[PlanContractGapRead]]:
+    query = db.query(PlPlan).filter(
+        PlPlan.tenant_no == tenant_no,
+        PlPlan.del_flag == 0,
+        PlPlan.follow_status != "cancelled",
+        plan_has_contract_gap_exists(),
+    )
+    query = apply_pl_scope(query, PlPlan, user, db, tenant_no)
+    # 可选筛选：plan_no / 日期 / 客户关键词 / q
+    # gap_type：在加载合同计数后内存过滤，或额外 AND 侧缺口表达式
+    query = query.order_by(PlPlan.plan_date.desc(), PlPlan.create_time.desc())
+    total = query.count()
+    rows = query.offset((page - 1) * page_size).limit(page_size).all()
+    # load_plan_contracts_grouped → compute_contract_gap_sides → 组装 PlanContractGapRead
+    ...
+```
+
+`gap_type` 推荐在 SQL 侧用与 `plan_has_contract_gap_exists` 相同的侧表达式再 AND，避免分页偏差。
+
+- [ ] **Step 2: 路由（必须写在 `@router.get("/{id}")` 之前）**
+
+```python
+@router.get("/contract-gaps", response_model=PlanContractGapListResponse)
+def list_contract_gaps(
+    page: int = Query(1, ge=1),
+    page_size: int = Query(20, ge=1, le=100, alias="pageSize"),
+    plan_no: Optional[str] = Query(None, alias="planNo"),
+    gap_type: Optional[str] = Query(None, alias="gapType"),
+    customer_keyword: Optional[str] = Query(None, alias="customerKeyword"),
+    plan_date_from: Optional[date] = Query(None, alias="planDateFrom"),
+    plan_date_to: Optional[date] = Query(None, alias="planDateTo"),
+    q: Optional[str] = Query(None),
+    db: Session = Depends(get_db),
+    user: DbUserContext = Depends(get_db_current_user),

+    tenant_no = get_tenant_no(db, user.to_tenant_user_dict())
+    total, items = list_plan_contract_gaps(...)
+    return PlanContractGapListResponse(total=total, list=items)
+```
+
+- [ ] **Step 3: 本地用 Swagger `/docs` 或 curl 冒烟（需登录态）**
+
+确认返回仅含缺合同、未作废计划。
+
+- [ ] **Step 4: 提交**
+
+```bash
+git commit -m "feat(pl): add GET transport/plan/contract-gaps endpoint"
+```

+
+- [ ] **Step 3: 手动验证**
+
+1. 只改供方合同，需方关联不变

+updateSideContracts: (id: string, side: 'supplier' | 'demander', contracts: PlanContractLink[]) =>
+  request.put<PlanContractGapItem>(`/transport/plan/${id}/contracts/${side}`, { contracts }),

+- [ ] **Step 2: 提交**

+
+### Task 8: 页面列表 + 行内展开（方案 B）
+
+**Files:**
+- Create: `web-admin/src/views/pl/plan-contract/index.vue`
+- Modify: `web-admin/src/App.vue`（如有 `panelTitleBarTextRules`，加入「运输计划合同完善」）
+
+- [ ] **Step 1: 页面骨架**
+
+对照 `plan-cert/index.vue` + Demo 方案 B：
+
+- `panel-top` 标题 + 「待完善 N 条」（可用 `total`）
+- `filter-block`：计划编号、缺口类型、供方/需方、计划日期
+- `list-toolbar`：`ListToolbarDateShortcuts` + `ListQuickSearchInput` + 刷新（**无新增**）
+- `el-table`：`type="expand"` 或自定义展开行；列：计划编号（`el-link`）、计划日期、供方、需方、合同缺口 Tag、跟进状态、操作
+- 分页：`list-body.list-wrap` + `el-pagination`
+- `PlPlanViewDialog`：编号链接 / 「查看计划」打开（同 plan-cert）
+
+缺口 Tag 映射：
+
+```typescript
+function gapTagLabel(sides: string[]) {
+  if (sides.includes('supplier') && sides.includes('demander')) return { text: '两侧均缺', type: 'danger' }
+  if (sides.includes('supplier')) return { text: '缺供方合同', type: 'warning' }
+  if (sides.includes('demander')) return { text: '缺需方合同', type: 'warning' }
+  return { text: '—', type: 'info' }
+}
+```
+
+跟进状态用现有 `PL_PLAN_FOLLOW_STATUS` / DictTag 方式（与 plan 列表一致）。
+
+- [ ] **Step 2: 展开区**
+
+- `expandedRowId` 仅允许一行；切换前若 `dirty` → `ElMessageBox.confirm`
+- 左右两栏：
+  - 豁免：灰态文案，无按钮
+  - 非豁免：`PlPlanContractMultiSelect`（`:required="false"`），本地 `v-model` 绑定草稿；「保存」调用 `planApi.updateSideContracts`
+- 保存成功：`ElMessage.success`；用返回的 `gapSides` 更新行；若 `gapSides.length===0` 则从 `tableData` 移除并刷新角标（若项目有 `refreshMenuBadges` / store 方法则调用，否则依赖下次进入菜单）
+- 保存按钮：有 `pl:plan-contract:update` 权限才显示（对齐项目权限指令，如 `v-hasPermi`；若本仓库用其它写法，跟随 `plan` 页批量操作权限模式）
+
+- [ ] **Step 3: 手动 UI 验收清单**
+
+1. 列表只有缺合同、未作废计划  
+2. 行内展开互斥；未保存收起有确认  
+3. 单侧保存后对侧不变；两侧齐后行消失  
+4. 无新建/编辑合同入口  
+5. 侧栏角标数字与列表 total 口径一致（同筛选默认条件）  
+6. Fresh Mint：标题竖条、筛选、工具栏「已选」规则本页无批量主按钮即可  
+
+- [ ] **Step 4: graphify + 提交**
+
+```bash
+./scripts/update-graph.sh all
+git add -A && git commit -m "feat(pl): add plan contract completion page with inline expand"
+```
+
+---
+
+### Task 9: Spec 状态与收尾
+
+- [ ] 将 `docs/superpowers/specs/2026-08-20-pl-plan-contract-complete-design.md` 状态改为「已实现（待联调验收）」
+- [ ] 确认增量 SQL 已在目标库执行，角色可见菜单
+- [ ] 提交 docs 状态更新
+
+```bash
+git commit -m "docs: mark plan contract completion design as implemented"
+```

+## Spec coverage checklist
+
+| Spec 要求 | Task |
+|-----------|------|
+| 独立菜单页路径 1 | 6, 8 |
+| 仅未作废；归档仍入列 | 3（filter 不含 archive_status） |
+| 缺口规则 / 内置可免 | 1, 2 |
+| 行内展开方案 B | 8 |
+| 每侧多选 | 8（ContractSelector multiple） |
+| 两侧各自保存 | 4, 8 |
+| 菜单角标 | 5, 6 |
+| 无合同 CRUD | 8（不引入合同表单） |
+| API contract-gaps / side PUT | 3, 4 |
+| 权限 list/update | 6, 8 |
+
+## Placeholder / 一致性自检
+
+- 路由前缀统一为前端已用的 `/transport/plan/...`（与 `planApi` 一致），对应后端 `app/api/pl/plan.py` router。
+- `side` 字面量：`supplier` / `demander`（与 `PLAN_CONTRACT_SIDE_*` 一致）。
+- `GET /contract-gaps` 必须注册在 `GET /{id}` 之前，避免被路径参数吞掉。
