+# 运输计划段次稳定 ID + 外围单据就地复用 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:** 保存/调整运输时保留装送货段与计划产品行主键，地磅关联就地更新、司机/现场 token 不轮换，避免反复编辑后详情出现「暂无关联地磅单」。
+
+**Architecture:** 将 `replace_plan_stops` 与计划产品更新改为按 payload `id` upsert；调整运输改为按段 `upsert_stop_dibang_links`（不再整批 revoke 再建）；默认不 rotate driver/site token。历史悬空 link 用运维脚本改挂（含 `PO20260904024`）。
+
+**Tech Stack:** FastAPI + SQLAlchemy + Pydantic v2 + pytest；Vue 3 + TypeScript
+
+**Spec:** `docs/superpowers/specs/2026-09-05-pl-stop-stable-id-reuse-links-design.md`
+
+**注意：** 工作区可能有无关未提交改动。只改本计划列出的文件，提交时勿夹带无关 diff。

+### Task 1: Schema — Body 可选 id
+
+**Files:**
+- Modify: `backend/app/schemas/pl/plan.py`
+- Modify: `docs/superpowers/specs/2026-09-05-pl-stop-stable-id-reuse-links-design.md`（状态 → 已确认）
+
+- [ ] **Step 1: 为写入 Body 增加可选 id**
+
+在 `PlanProductCreate` 增加：
+
+```python
+id: Optional[str] = Field(default=None, description="已有计划产品行ID；编辑回传以保留主键")
+```
+
+在 `PlanLoadBody` / `PlanDeliveryBody` 顶部增加：
+
+```python
+id: Optional[str] = Field(default=None, description="已有段ID；编辑回传以保留主键")
+```
+
+- [ ] **Step 2: 更新设计文档状态**
+
+将 spec 头部 `状态：待审阅…` 改为 `状态：已确认`。
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add backend/app/schemas/pl/plan.py docs/superpowers/specs/2026-09-05-pl-stop-stable-id-reuse-links-design.md
+git commit -m "$(cat <<'EOF'
+feat(pl): allow optional stop/product ids on plan write bodies.
+
+EOF
+)"
+```
+

+
+### Task 2: 送货段 upsert（核心）
+
+**Files:**
+- Create: `backend/tests/test_pl_plan_stop_upsert.py`
+- Modify: `backend/app/services/pl_plan_stop_service.py`
+
+- [ ] **Step 1: 写失败单测（期望 upsert 保留 delivery id）**
+
+```python
+"""replace_plan_stops 应按 payload.id upsert 送货段，而非每次换新 UUID。"""
+from unittest.mock import MagicMock
+
+import pytest
+from fastapi import HTTPException
+
+from app.services.pl_plan_stop_service import resolve_delivery_id_for_upsert

+
+def test_upsert_delivery_rejects_foreign_plan_id():
+    with pytest.raises(HTTPException) as ei:
+        resolve_delivery_id_for_upsert(

+            payload_id="del-other-plan",
+            existing_by_id={},
+        )
+    assert ei.value.status_code == 422

+        existing_by_id={},

+    assert new_id == "new-del"
+    assert row is None
+```
+
+- [ ] **Step 2: 运行确认失败**
+
+```bash
+cd backend && source venv/bin/activate
+pytest tests/test_pl_plan_stop_upsert.py -v
+```
+
+Expected: FAIL（`resolve_delivery_id_for_upsert` 未定义）
+
+- [ ] **Step 3: 实现 upsert 辅助函数并改造 `replace_plan_stops`**
+
+在 `pl_plan_stop_service.py`：
+
+1. **不要再**对全部 delivery `del_flag=1` 后无脑 `generate_uuid()`。
+2. 算法：
+   - 查询本计划全部 delivery（含 `del_flag=1`，用于复活）。
+   - `kept_ids = set()`
+   - 对每个 `PlanDeliveryBody`：
+     - 若 `body.id`：必须在本计划 map 中，否则 422；取该行 UPDATE 字段并 `del_flag=0`；`delivery_id = body.id`
+     - 若无 `body.id`：`delivery_id = generate_uuid()` INSERT
+     - `kept_ids.add(delivery_id)`
+     - 段产品：对该 delivery 旧产品软删后按行写入；`plan_product_id` 继续走 `_resolve_plan_product_id`
+   - 未在 `kept_ids` 的旧有效 delivery → `del_flag=1`（及其段产品）
+3. 装货段：保持现有 `_resolve_or_create_plan_load`。
+4. 合同行：可继续按现逻辑重写；本期硬目标是段 id 稳定。
+
+```python
+from typing import Optional
+
+def resolve_delivery_id_for_upsert(
+    *,
+    plan_id: str,
+    payload_id: Optional[str],
+    existing_by_id: dict,
+) -> tuple[str, Optional[object]]:
+    pid = (payload_id or "").strip()
+    if not pid:
+        return generate_uuid(), None
+    row = existing_by_id.get(pid)
+    if row is None or getattr(row, "plan_id", None) != plan_id:
+        raise HTTPException(status_code=422, detail=f"送货段 id 无效或不属于本计划：{pid}")
+    return pid, row
+```
+
+将 `replace_plan_stops` 中送货循环的 `delivery_id = generate_uuid()` 替换为上述解析 + UPDATE/INSERT。
+
+- [ ] **Step 4: 跑通单测**
+
+```bash
+pytest tests/test_pl_plan_stop_upsert.py -v
+```
+
+Expected: PASS
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add backend/app/services/pl_plan_stop_service.py backend/tests/test_pl_plan_stop_upsert.py
+git commit -m "$(cat <<'EOF'
+feat(pl): upsert plan deliveries by stable id on save.
+
+EOF
+)"
+```
+
+---
+
+### Task 3: 计划产品行 upsert
+
+**Files:**
+- Modify: `backend/app/services/pl_plan_service.py`（`build_plan_product`）
+- Modify: `backend/app/api/pl/plan.py`（update 产品块 ~1647–1706）
+- Create/Extend: `backend/tests/test_pl_plan_product_upsert.py`
+
+- [ ] **Step 1: `build_plan_product` 支持传入 id**
+
+```python
+def build_plan_product(..., product_row_id: Optional[str] = None) -> PlPlanProduct:
+    return PlPlanProduct(
+        id=(product_row_id or "").strip() or generate_uuid(),
+        ...
+    )
+```
+
+- [ ] **Step 2: update_plan 产品路径改为 upsert**
+
+替换「全体 `del_flag=1` 再全新建」：
+
+```python
+existing_all = db.query(PlPlanProduct).filter(
+    PlPlanProduct.plan_id == id,
+    PlPlanProduct.tenant_no == tenant_no,
+).all()
+existing_all_by_id = {row.id: row for row in existing_all}
+kept: list[PlPlanProduct] = []
+kept_ids: set[str] = set()
+for idx, prod in enumerate(payload.products):
+    row_id = (getattr(prod, "id", None) or "").strip()
+    if row_id and row_id in existing_all_by_id and existing_all_by_id[row_id].plan_id == id:
+        row = existing_all_by_id[row_id]
+        # 更新名称/数量/证书等字段，del_flag=0
+        kept.append(row)
+        kept_ids.add(row_id)
+    else:
+        pp = build_plan_product(..., product_row_id=None)
+        db.add(pp)
+        kept.append(pp)
+        kept_ids.add(pp.id)
+for row in existing_all:
+    if row.del_flag == 0 and row.id not in kept_ids:
+        row.del_flag = 1
+plan_products = kept
+```
+
+create-full 新建仍可不传 id。
+
+- [ ] **Step 3: 单测 — 带 id 时主键不变**
+
+断言：`build_plan_product(..., product_row_id="pp-1").id == "pp-1"`；无 id 时走 `generate_uuid`。
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add backend/app/services/pl_plan_service.py backend/app/api/pl/plan.py backend/tests/test_pl_plan_product_upsert.py
+git commit -m "$(cat <<'EOF'
+feat(pl): upsert plan product rows by id on update.
+
+EOF
+)"
+```
+
+---
+
+### Task 4: 前端回传段 / 产品 id
+
+**Files:**
+- Modify: `web-admin/src/utils/pl-plan-stop-form.ts`
+- Modify: `web-admin/src/components/business/pl-plan-form-dialog/index.vue`（产品 payload）
+- Modify: `web-admin/src/api/pl/index.ts`（若类型缺 `products[].id`）
+
+- [ ] **Step 1: 表单类型与 map/build**
+
+`PlanLoadForm` / `PlanDeliveryForm` 增加 `id?: string`。
+
+`mapLoadFromApi` / `mapDeliveriesFromApi`：
+
+```typescript
+id: load.id || undefined
+// deliveries:
+id: row.id || undefined
+```
+
+`createEmptyLoadForm` / `createEmptyDeliveryForm`：不设 id。
+
+`buildLoadPayload` / `buildDeliveriesPayload`：
+
+```typescript
+...(load.id ? { id: load.id } : {}),
+// delivery:
+...(row.id ? { id: row.id } : {}),
+```
+
+- [ ] **Step 2: 计划产品提交带 id**
+
+在 `buildPlanCommonPayload` / 最终 `products` 数组中，对已有行带上 `id: row.id`。确认类型允许 `products[].id`。
+
+- [ ] **Step 3: 手工确认**
+
+编辑已有计划 → PUT body 的 `load.id`、`deliveries[].id`、`products[].id` 非空；新增送货段无 `id`。
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add web-admin/src/utils/pl-plan-stop-form.ts web-admin/src/components/business/pl-plan-form-dialog/index.vue web-admin/src/api/pl/index.ts
+git commit -m "$(cat <<'EOF'
+feat(web-admin): submit stable load/delivery/product ids on plan save.
+
+EOF
+)"
+```
+

+
+### Task 5: 地磅按段 upsert（替代整批 revoke 再建）
+
+**Files:**
+- Create: `backend/tests/test_pl_dibang_upsert_on_arrange.py`
+- Modify: `backend/app/services/pl_dibang_bridge_service.py`
+- Modify: `backend/app/api/pl/transport.py`
+- Modify: `backend/app/api/pl/plan.py`（已安排 PUT 后调用）
+
+- [ ] **Step 1: 写单测骨架**
+
+```python
+def test_cancel_generate_dibang_blocked_when_weighing_exists():
+    # mock link + inventory + _inventory_has_weighing_slip True
+    # generate_dibang=0 → ValueError 含批次号
+
+def test_upsert_reuses_existing_inventory_id():
+    # 已有 link(stop_id=del-1, db_inventory_id=inv-1)
+    # upsert 同 stop → 返回同一 inv-1，不新建
+```
+
+- [ ] **Step 2: 实现 `upsert_stop_dibang_links`**
+
+相对现 `sync_dibang_for_plan_stops` + `_sync_stop_inventory_links`：
+
+1. 查本 plan/transport 有效 links。
+2. 勾选段+产品：已有 `(stop_type, stop_id, plan_product_id)` → 未过磅则更新可变字段；过磅则跳过并 `warnings`。无则新建 inventory + link。
+3. 取消勾选：有有效过磅 → `raise ValueError`；否则软删 link + 出入库并回减月计划贡献。
+4. link 存在且段 `product_id` 与出入库不一致 → `raise ValueError`（禁止静默换产品）。
+
+可扩展 `sync_linked_dibang_dates_for_plan` 或并列字段同步：`partner_company` / `vehicle_no` / `quantity`（未过磅可写）。
+
+- [ ] **Step 3: 改 `transport.py` 安排路径**
+
+- 去掉 rearrange 前整批 `revoke_regeneratable_dibang_for_transport`（取消勾选改由 upsert 按条处理）。
+- `sync_dibang_for_plan_stops` 改为 upsert；首次安排无 link = 新建。
+
+- [ ] **Step 4: 已安排计划 PUT**
+
+在 `update_plan` 于 `replace_plan_stops` + 日期同步之后，若已安排则调用同一 upsert / 取消勾选校验（spec §4.2）。
+
+- [ ] **Step 5: 跑测**
+
+```bash
+pytest tests/test_pl_dibang_upsert_on_arrange.py tests/test_pl_dibang_date_sync_on_plan_save.py -v
+```
+
+Expected: PASS
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add backend/app/services/pl_dibang_bridge_service.py backend/app/api/pl/transport.py backend/app/api/pl/plan.py backend/tests/test_pl_dibang_upsert_on_arrange.py
+git commit -m "$(cat <<'EOF'
+feat(pl): upsert dibang links in place instead of revoke-and-recreate.
+
+EOF
+)"
+```
+
+---
+
+### Task 6: 调整运输默认不 rotate token
+
+**Files:**
+- Modify: `backend/app/api/pl/transport.py`
+- Extend: 相关 tests
+
+- [ ] **Step 1: 改 rearrange 分支**
+
+将 rotate 改为 ensure（仅缺失时生成）：
+
+```python
+if is_rearrange:
+    _ensure_driver_access_token(transport)
+    if needs_site_link and plan_has_load_stop(db, tenant_no, plan.id):
+        ensure_transport_site_token(transport)
+    elif not needs_site_link:
+        transport.site_access_token = None
+        # 既有 void_io_orders 逻辑按需保留
+else:
+    _ensure_driver_access_token(transport)
+```
+
+保留 `_rotate_*` 供未来「作废并重发」，本期不调用。
+
+- [ ] **Step 2: 单测 — rearrange 后 token 不变**
+
+已有 token 的 transport 走 rearrange 后 `driver_access_token` / `site_access_token` 相等。
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add backend/app/api/pl/transport.py backend/tests/
+git commit -m "$(cat <<'EOF'
+fix(pl): keep driver/site tokens stable on rearrange.
+
+EOF
+)"
+```
+
+---
+
+### Task 7: 历史悬空 link 修复（含 PO20260904024）
+
+**Files:**
+- Create: `backend/scripts/fix_pl_transport_db_link_stop_ids.py`
+- Create: `docs/sql/migrations/2026-09-05-fix-pl-db-link-orphaned-stop.sql`
+
+- [ ] **Step 1: 脚本逻辑**
+
+对每个有效 `pl_transport_db_link`：
+
+1. `stop_type=delivery` 且 stop 已软删/不存在 → 同计划有效 delivery：优先同 `customer_name`；仅 1 条则唯一匹配。
+2. `plan_product_id` 已软删 → 同计划有效产品按相同 CRM `product_id` 改挂。
+3. 默认 dry-run；`--apply` 才写库；支持 `--plan-no PO20260904024`。
+
+期望案例输出：
+
+```
+stop_id 1D4CB037… → 2036E1B2…
+plan_product_id DA6B3548… → 537B42A6…
+```
+
+- [ ] **Step 2: SQL 备忘**
+
+```sql
+UPDATE pl_transport_db_link
+SET stop_id = '2036E1B2CEC54509ABC2B22DAA5786F3',
+    plan_product_id = '537B42A6B7E54D7CBD4C90DC73B185E7',
+    update_time = NOW()
+WHERE id = '4AAE759627054CAAB6B5F36D4888CBA4'
+  AND plan_id = '551307353C99489786756A3F26C49020'
+  AND del_flag = 0;
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add backend/scripts/fix_pl_transport_db_link_stop_ids.py docs/sql/migrations/2026-09-05-fix-pl-db-link-orphaned-stop.sql
+git commit -m "$(cat <<'EOF'
+chore(pl): add script to remount orphaned transport dibang stop links.
+

+```
+
+- [ ] **Step 4: 生产修复（人工确认后执行，不自动跑）**
+
+```bash
+cd backend && source venv/bin/activate

+python scripts/fix_pl_transport_db_link_stop_ids.py --plan-no PO20260904024 --apply
+```
+

+
+### Task 8: 回归清单与 graphify
+
+- [ ] **Step 1: 自动化回归**
+
+```bash
+cd backend && source venv/bin/activate
+pytest tests/test_pl_plan_stop_upsert.py tests/test_pl_plan_product_upsert.py tests/test_pl_dibang_upsert_on_arrange.py tests/test_pl_dibang_date_sync_on_plan_save.py tests/test_pl_plan_stop_service.py -v
+```
+
+Expected: PASS
+
+- [ ] **Step 2: 手工验收（spec §8）**
+
+1. 安排 → 改地址保存/调整 → 段 id、出入库 id、批次号不变；详情有地磅。
+2. 过磅后改地址 → 计划可存；详情仍有地磅。
+3. 过磅后取消地磅勾选 → 失败提示。
+4. 新增多段勾地磅 → 只新建新段单据。
+5. 调整运输 → 司机/现场旧链接仍可用。
+6. 复制计划 → 无源单 link。
+7. 修复后 `PO20260904024` 送货段可见磅单。
+
+- [ ] **Step 3: 更新知识图谱**
