+# affiliate_dash 商户接入对接文档（方案 B：统一领取页深度集成）
+
+> 文档对象：order_site 后端 / 前端对接开发
+> 版本：v1（评审稿）
+> 对接方向：order_site 作为 **affiliate_dash 的一个商户**，走商户开放接口 `/api/client/v1`，由 affiliate_dash 完成皮肤/道具履约，order_site 保持自己的统一领取页并自建发货交互。
+
+---
+
+## 0. 一句话结论
+
+order_site 在 affiliate_dash 开通一个商户账号 + API 客户端，下单时调用 `POST /api/client/v1/orders` 幂等建单扣款，领取页通过 `delivery` 系列接口（查询 → 绑定 → 轮询 → 提交）在**本站页面内**完成发货交互，最终由 affiliate_dash 回调 `order.shipping.updated` 驱动 order_site 任务状态与快手电子凭证核销闭环。
+
+---
+
+## 1. 角色与职责边界
+
+| 方 | 承担 | 不承担 |
+| --- | --- | --- |
+| **order_site** | 91 进单、商品匹配、履约任务、统一领取页、玩家信息收集、回调接收、电子凭证核销、人工兜底 | 不直接对接皮肤源头；不管理 affiliate_dash 钱包 |
+| **affiliate_dash** | 商户建单扣款、发货数据查询、绑定、对源头履约、回调推送 | 不接触 91 卡券，不生成 order_site 的 claimUrl |
+
+> 对接方式与现有 `kuaishou-feifei` 执行器同构：order_site 新增一个 `affiliate_dash` executor，复用一个 `preparePaidTask` + `resolveDeliveryLink`，对外仍然只返回本站统一领取链接。
+
+---
+
+## 2. 对接前准备（affiliate_dash 侧，管理员手动完成）
+
+| 项 | 说明 |
+| --- | --- |
+| 商户账号 | affiliate_dash 后台新建商户（如 `order_site`），状态 active |
+| API 客户端 | 商户后台「API 密钥」新建，scopes 至少含 `products:read`、`orders:read`、`orders:write`、`shipping:read`、`wallet:read`；保存 `app_key` / `secret`（secret 仅创建时展示一次） |
+| 回调配置 | 商户后台「回调」配置接收 URL（指向 order_site 回调路由），订阅事件 `order.created`、`order.shipping.updated`、`order.cancelled`，保存回调 secret |
+| 钱包充值 | affiliate_dash 无真实支付，**下单即扣商户钱包积分**；上线前需充值足够积分 |
+| 环境 | 记录 `BASE_URL`（如 `https://affiliate.example.com`），确认网络可达；时间偏差容差 ±300 秒，服务器需 NTP 同步 |
+
+---
+
+## 3. 鉴权与签名
+
+### 3.1 请求签名（order_site → affiliate_dash `/api/client/v1`）
+
+Header：
+
+| Header | 必填 | 说明 |
+| --- | --- | --- |
+| `X-App-Key` | 是 | 商户 API 客户端 app_key |
+| `X-Timestamp` | 是 | Unix 秒时间戳 |
+| `X-Nonce` | 是 | 随机串 8～96 位；同 Key 有效期内不可重复（服务端持久化防重放） |
+| `X-Sign` | 是 | 见下 |
+
+签名字符串（**body 先 sha256**，与源头侧 `/api/open/v1` 的原始 body 拼串不同，勿混用；参数名是 **`app_key`** 而非旧接口的 `api_key`，写错会 401）：
+
+```text
+app_key=<app_key>&body_sha256=<sha256hex(body)>&method=<GET|POST>&nonce=<nonce>&path=<仅路径>&timestamp=<unix秒>
+```
+
+规则：
+
+1. 参数按 ASCII 字典序排序（固定为上面顺序）；
+2. value 原样拼接不做 URL encode；GET 请求 body 为空字符串（`body_sha256` 为空串的 sha256）；
+3. `X-Sign = hex(HMAC-SHA256(secret, 签名字符串))`，小写。
+
+TypeScript 参考：
+
+```ts
+import { createHmac, createHash } from 'node:crypto'
+
+function sha256Hex(input: string): string {
+  return createHash('sha256').update(input, 'utf8').digest('hex')
+}
+
+function hmacSha256Hex(secret: string, content: string): string {
+  return createHmac('sha256', secret).update(content, 'utf8').digest('hex')
+}
+
+export function buildClientSign(params: {
+  appKey: string
+  appSecret: string
+  method: string
+  path: string
+  body: string
+  timestamp: string
+  nonce: string
+}): string {
+  const content = [
+    `app_key=${params.appKey}`,
+    `body_sha256=${sha256Hex(params.body)}`,
+    `method=${params.method.toUpperCase()}`,
+    `nonce=${params.nonce}`,
+    `path=${params.path}`,
+    `timestamp=${params.timestamp}`,
+  ].sort().join('&')
+  return hmacSha256Hex(params.appSecret, content)
+}
+```
+
+### 3.2 回调验签（affiliate_dash → order_site）
+
+Header：`X-Event-ID`、`X-Timestamp`、`X-Sign`
+
+```text
+content = body_sha256=<sha256hex(原始body)>&timestamp=<X-Timestamp>
+X-Sign  = hex(HMAC-SHA256(回调secret, content))
+```
+
+校验顺序：`X-Timestamp` 在 ±300 秒内 → 按 `X-Event-ID` 幂等去重 → 重算签名比对（`timingSafeEqual`）→ 处理业务。校验失败返回 4xx，成功尽快返回 2xx（affiliate_dash 会重试最多 16 次，间隔为固定递增序列 `15s/15s/30s/3m/10m/20m/30m/30m/30m/1h/3h/3h/3h/6h/6h`，非严格指数退避）。
+
+---
+
+## 4. 商品映射
+
+- 拉取：`GET /api/client/v1/products`（分页 `page`/`size`），关键字段：
+
+| 字段 | 说明 |
+| --- | --- |
+| `list[].sku` | 下单时作为 `sku` 传入 |
+| `list[].display_name` | 商户展示名 |
+| `list[].price_amount` | 单价（积分） |
+| `list[].stock` | 库存，`-1` 不限 |
+| `list[].status` | `active` 可售 |
+
+- order_site 侧在履约配置（`fulfillment_profiles.config_json`）维护映射：**91 productNo / order_site 商品 → affiliate_dash sku**。
+- 建议：admin 配置页支持手动关联 + 定时同步（商品下架/缺货在领取前拦截，转人工）。
+
+---
+
+## 5. 完整时序（方案 B）
+
+```text
+91 卡券下单
+  └→ order_site 建内部订单 + 履约 task（executor_key = affiliate_dash）
+       └→ preparePaidTask：
+            POST /api/client/v1/orders
+              { client_order_no: <order_site 内部单号>, sku, quantity, buyer_reference, data: { 91单号, 预期游戏账号 } }
+            → affiliate_dash 扣钱包积分，建单（order_no, order_status=paid）
+            → order_site 从 201 响应**同步**拿到 order_no，写入 task 上下文，task → link_generated
+            → 异步回调 order.created 仅作对账/补发（幂等，不改变 task 状态）
+       └→ resolveDeliveryLink：返回本站统一 claimUrl
+91 把 claimUrl 发给用户
+用户打开 order_site 领取页（executor_key=affiliate_dash 分支）
+  └→ 展示商品/预期账号
+  └→ 用户输入/确认游戏 UID → POST /orders/{order_no}/delivery/bind
+       → 展示 bind_url / qr_url（或跳转绑定）
+  └→ 轮询 GET /orders/{order_no}/delivery/bind-result（2~3 秒）
+       → bound=true（含 mismatch 提示）→ 展示角色信息
+  └→ POST /orders/{order_no}/delivery/submit { game_account, bind_uuid }
+       → affiliate_dash 进入 delivering，内部对源头发货
+affiliate_dash 履约完成（delivered / ship_failed）
+  └→ 回调 order.shipping.updated
+       → order_site 验签 + 幂等 → 更新 task 状态
+       → delivered：task → redeemed/completed，触发快手电子凭证核销
+       → ship_failed：task → retry_pending/manual_review，展示失败原因
+```
+
+---
+
+## 6. 接口明细（order_site 实际使用的端点）
+
+### 6.1 创建订单 `POST /api/client/v1/orders`（scope `orders:write`）
+
+| body | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `client_order_no` | string | 是 | **幂等单号**，同一商户下唯一；建议用 order_site 内部单号 |
+| `sku` | string | 是 | affiliate_dash 商品 sku |
+| `quantity` | int | 否 | 默认 1 |
+| `buyer_reference` | string | 否 | 买家标识/备注（可填 91 单号或用户标识） |
+| `data` | object | 否 | 透传业务数据（≤2048B）；约定字段 `game_account`/`game_channel`/`role_name` 会用于发货处理；回调原样带回 |
+
+响应 `data.order`：`order_no`、`client_order_no`、`order_status`（=paid）、`can_ship`、`cannot_ship_reason`、`amount`、`base_amount`、`service_fee_amount`、`currency` 等。
+
+注意：
+
+- 成功创建 HTTP **201**；命中幂等返回 **200** 且 `idempotent=true` + 既有订单，**不重复扣款**；
+- **无真实支付，下单即扣钱包积分**，余额不足返回 400 —— order_site 必须处理该降级；
+- 下单后以 `order_no` 为准进行后续查询/发货/回调匹配。
+
+### 6.2 查询订单 `GET /api/client/v1/orders/{order_no}`（`orders:read`）
+
+返回订单当前状态、金额、失败原因等（⚠️ 实际响应**不含**「发货链接有效期」字段，有效期仅在 delivery-link 接口返回）；用于 order_site 主动对账/兜底轮询。
+
+### 6.3 获取发货链接 `GET /api/client/v1/orders/{order_no}/delivery-link`（`orders:read`/`shipping:read`）
+
+返回 `delivery_url`（可直接打开的 affiliate_dash Web 发货页）。方案 B 下作为**备选**（如自建页临时不可用时直接跳转）。
+
+### 6.4 查询发货数据 `GET /api/client/v1/orders/{order_no}/delivery`（`orders:read`/`shipping:read`）
+
+自建发货页的渲染数据：`status`、`can_ship`、`cannot_ship_reason`、`product`、`buyer_name`、`game_channel`、`game_uid`、`role_name`、`pay_score`、`data`（下单透传，用于预填玩家账号）、`good`（商品展示详情）。
+
+### 6.5 发起绑定 `POST /api/client/v1/orders/{order_no}/delivery/bind`（`orders:write`）
+
+| body | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `game_account` | string | 是 | 玩家编号 / UID |
+
+返回 `bind_uuid`（提交发货凭证）、`bind_url`（绑定跳转地址）、`qr_url`（绑定二维码）。同一订单重复绑定以最新凭证为准。
+
+### 6.6 查询绑定结果 `GET /api/client/v1/orders/{order_no}/delivery/bind-result?bind_uuid=..`（`orders:read`/`shipping:read`）
+
+| 字段 | 说明 |
+| --- | --- |
+| `bound` | 是否完成绑定；未绑定 `false`，自建页每 2~3 秒轮询 |
+| `game_account` / `role_name` / `game_channel` | 绑定成功后返回 |
+| `expected_game_account` | 下单 `data.game_account` 透传的预期账号（有传才返回） |
+| `mismatch` | 绑定账号与预期不一致时为 `true`；**提交发货会被拒绝** |
+
+### 6.7 提交发货 `POST /api/client/v1/orders/{order_no}/delivery/submit`（`orders:write`）
+
+| body | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `game_account` | string | 是 | 玩家编号 / UID |
+| `bind_uuid` | string | 是 | 绑定凭证 |
+
+返回 `order_no`、`status`（=delivering）、`message`、`provider_order_no`。同一订单重复提交直接返回既有结果。**最终成败以回调为准**。
+
+### 6.8 余额查询 `GET /api/client/v1/wallet`（`wallet:read`）
+
+可选：下单前预检余额，或在订单创建 400 时告警。返回 `available_balance`、`currency` 等。
+
+---
+
+## 7. 回调契约
+
+| 事件 | 触发时机 |
+| --- | --- |
+| `order.created` | 商户下单成功（扣款完成，order_status=paid） |
+| `order.shipping.updated` | 发货状态变化（delivering / delivered / ship_failed） |
+| `order.cancelled` | 订单取消/退款 |
+
+payload（统一结构）：
+
+```json
+{
+  "event_id": "…",
+  "event": "order.shipping.updated",
+  "occurred_at": "…",  // 真实实现含此字段
+  "data": {
+    "order_no": "FO20260730000123",
+    "client_order_no": "shop-10001",
+    "product_sku": "suit_pink_sheep",
+    "quantity": 1,
+    "base_amount": 100,
+    "service_fee_amount": 1,
+    "amount": 101,
+    "currency": "POINT",
+    "order_status": "delivered",
+    "can_ship": false,
+    "cannot_ship_reason": "",
+    "provider_order_no": "…",
+    "failure_reason": "",
+    "data": { "91单号": "…", "game_account": "4808146277" }
+  }
+}
+```
+
+order_site 处理要求：
+
+1. 验签（见 3.2）；
+2. 按 `X-Event-ID` / `event_id` 幂等（DB 唯一键或去重表）；
+3. `order_status` → task 状态迁移（见下）；
+4. 尽快返回 2xx；失败重试可能重复投递（最多 16 次指数退避）。
+
+---
+
+## 8. 状态映射
+
+| affiliate_dash `order_status` | order_site task 状态 / 动作 |
+| --- | --- |
+| `paid` | 已建单待履约（task `link_generated`，领取页可开始发货） |
+| `delivering` | 履约中（task `redeeming`，领取页展示处理中） |
+| `delivered` | 履约成功（task → `redeemed` / `completed`；触发快手电子凭证核销） |
+| `ship_failed` | 履约失败（task → `retry_pending`；可重新 `delivery/submit` 或转 `manual_review`） |
+| `cancelled` | 已取消/退款（task → `closed`，通知 91/用户） |
+
+> ⚠️ **状态机合法性**（对照 `apps/backend/src/domain/task-status.ts` 的 `TASK_TRANSITIONS`）：
+> - affiliate_dash 流程中 task 须经过 `link_generated → claimed → waiting_binding → redeeming` 才能进入履约态：`link_generated`/`claimed` **不能**直接跳 `redeeming`（不在转移表）。落地时：领取页打开置 `claimed`、提交绑定置 `waiting_binding`、`delivery/submit` 成功或收到 delivering 回调置 `redeeming`。
+> - `redeeming → redeemed/completed/retry_pending/manual_review` 均合法；`redeeming → closed` 不在转移表（`updateTask` 实际不校验转移表，属软约束，仍建议先经 `manual_review` 再 `closed`）。
+> - `retry_pending/manual_review → redeeming` 合法，支持 ship_failed 重试闭环。
+
+---
+
+## 9. 错误与降级
+
+| 场景 | affiliate_dash 返回 | order_site 处理 |
+| --- | --- | --- |
+| 钱包余额不足 | 创建订单 400 | task → `manual_review` + 告警「affiliate_dash 余额不足」，充值后重试 |
+| 商品下架/缺货 | 创建订单 400 | 匹配阶段拦截，转人工 |
+| 下单超时/网络失败 | 无响应 | 用同 `client_order_no` 幂等重试；仍失败转 `manual_dispatch` |
+| 绑定账号不匹配 | `mismatch=true`，submit 被拒 | 领取页提示买家绑回预期账号或重新下单 |
+| `ship_failed` | 回调 failure_reason | 领取页/后台展示原因，支持重试或转人工 |
+
+---
+
+## 10. 幂等与一致性设计
+
+- **下单幂等**：`client_order_no` = order_site 的 `task_no`（格式 `DT` + 12 hex，唯一且稳定，见 §14.2），重复请求安全；
+- **回调幂等**：`X-Event-ID` 去重；
+- **提交发货幂等**：重复 `delivery/submit` 返回既有结果；
+- **对账兜底**：order_site 定时用 `GET /orders/{order_no}` 对账（可选，回调为主）；
+- **时间**：双方服务器 NTP 同步，容差 ±300 秒。
+
+---
+
+## 11. order_site 配置清单（履约配置扩展）
+
+`fulfillment_profiles` 新增 profile：
+
+```json
+{
+  "profile_key": "affiliate_dash",
+  "name": "affiliate_dash 履约",
+  "executor_key": "affiliate_dash",
+  "requires_claim": true,
+  "auto_dispatch": false,
+  "config_json": {
+    "baseUrl": "https://affiliate.example.com",
+    "appKey": "ak_…",
+    "appSecret": "sk_…",
+    "callbackSecret": "…",
+    "skuMapping": { "91商品编码": "affiliate_dash sku" },
+    "fallbackExecutor": "manual_dispatch",
+    "precheckBalance": true
+  }
+}
+```
+
+商品匹配规则（复用 `fulfillment-routing.ts`）：91 productNo → 命中 affiliate_dash 映射 → `executor_key = affiliate_dash`；未命中走现有 kuaishou / manual 流程。
+
+---
+
+## 12. 对接计划（分阶段）
+
+| 阶段 | 内容 | 交付物 | 验收点 |
+| --- | --- | --- | --- |
+| **0. affiliate_dash 侧准备**（手动） | 建商户、API 客户端、回调配置、充值 | 商户可登录、app_key/secret 可用 | 用 curl 调 `GET /products` 通 |
+| **1. 平台客户端与签名** | `services/platforms/affiliate-dash/`：签名、请求封装、验签 | `client.ts`、`verify-callback.ts` | 单元测试：签名向量、验签通过/篡改拒绝 |
+| **2. executor** | `affiliate-dash-executor.ts`：`preparePaidTask`（建单+存 order_no）+ `resolveDeliveryLink`（统一 claimUrl）；注册进 `registry.ts` | executor + 注册 | 测试订单：91 进单 → task 状态 `link_generated`，affiliate_dash 出现订单 |
+| **3. 履约配置与商品映射** | 新增 profile、admin 配置页（sku 映射/余额预检） | 配置页 + 迁移 | 配置页可保存，路由规则生效 |
+| **4. 领取页（方案 B 自建）** | 前端按 executor 分发到 affiliate-dash 流程：`delivery` 查数据 → 输入 UID → `bind` → 轮询 `bind-result` → `submit`；异常分支（mismatch/失败重试） | 领取页分支 | 端到端：用户领取 → 绑定 → 提交 → affiliate_dash 显示 delivering |
+| **5. 回调路由与状态同步** | `POST /webhooks/affiliate-dash`：验签 + 幂等 + task 状态迁移 + 核销触发 | 回调路由 | 发货完成回调 → task `redeemed` + 电子凭证核销闭环 |
+| **6. 联调与上线** | 错误/降级演练、对账、监控告警 | 上线 checklist | 全链路绿灯，余额不足/绑定不匹配演练通过 |
+
+---
+
+## 13. 参考代码位置
+
+- order_site executor 模式：`apps/backend/src/services/fulfillment/executors/kuaishou-feifei-executor.ts`（最接近，同为「建单 + 统一领取链接」）、`registry.ts`（注册）、`types.ts`（接口定义）
+- order_site 平台对接样例：`apps/backend/src/services/platforms/kuaishou-feifei/`
+- order_site 履约配置：`apps/backend/src/repositories/fulfillment-profile-repo.ts`、`apps/backend/src/routes/admin/platform-config/fulfillment-routing.ts`
+- affiliate_dash 接口契约（在线文档/字段定义）：`frontend/src/openapi/endpoints.ts`；鉴权实现：`backend/internal/middleware/open_auth.go`（商户侧）、`backend/internal/service/callback.go`（回调签名 `BuildCallbackSign`）
+
+---
+
+## 14. 深度分析（契约验证结论 · v1 → v2）
+
+> 本节基于对 affiliate_dash 实际代码（`backend/internal/middleware/open_auth.go`、`backend/internal/service/callback.go`、`backend/internal/handler/open_v1.go`、`backend/internal/service/delivery.go`、`frontend/src/openapi/endpoints.ts` 等）与 order_site 履约体系（`domain/task-status.ts`、`services/fulfillment/executors/*`、`services/claim/*`）的逐项核对。以下结论是阶段 1~6 实现的直接依据。
+
+### 14.1 契约验证对照（文档 vs affiliate_dash 实际实现）
+
+| # | 契约项 | 结论 |
+|---| --- | --- |
+| 1 | 签名串参数名：文档原写 `api_key=`，实现为 `app_key=`（open_auth.go:194 `BuildOpenV1Sign`；前端在线文档 OpenApiDocs.tsx:425-449 与调试页 ApiDebugger.tsx:65 均用 `app_key=`） | ❌ 已在本版修正；按旧写法签名必然 401 |
+| 2 | body 先 sha256、参数字典序、四头、nonce 持久化防重放（长度 8~96）、±300s（OPEN_SIGN_SKEW=300）、scopes（products:read/orders:read/orders:write/shipping:read/wallet:read） | ✅ 一致 |
+| 3 | 回调 `content=body_sha256=<..>&timestamp=<..>`、头 X-Event-ID/X-Timestamp/X-Sign、事件枚举 order.created/order.shipping.updated/order.cancelled | ✅ 一致 |
+| 4 | 回调重试 16 次 | ⚠️ 次数一致（CALLBACK_MAX_ATTEMPTS=16），但为固定递增间隔序列而非严格指数退避（callback.go:30-46） |
+| 5 | POST /orders 字段、新建 201 / 幂等 200 + idempotent=true、余额不足 400、order 响应字段（order_no/order_status/can_ship/cannot_ship_reason/amount/base_amount/service_fee_amount/currency + client_order_no/product/quantity/fee_type/buyer_reference/provider_order_no/failure_reason/data/result/created_at/delivered_at/cancelled_at） | ✅ 一致 |
+| 6 | GET /products 字段与分页 page/size（status 恒为 active）；GET /orders/{order_no}；delivery-link → delivery_url/expires_at；delivery → status/can_ship/cannot_ship_reason/product/buyer_name/game_channel/game_uid/role_name/pay_score/data/good；bind → bind_uuid/bind_url/qr_url；bind-result → bound/game_account/role_name/game_channel/expected_game_account/mismatch；submit → order_no/status/message/provider_order_no；wallet → available_balance/currency | ✅ 一致（唯一修正：查询订单响应不含「发货链接有效期」，见 §6.2） |
+| 7 | 回调 payload 字段 + 顶层 `occurred_at`（真实存在，§7 已补） | ✅ 一致 |
+| 8 | order_status 五枚举 paid/delivering/delivered/ship_failed/cancelled；mismatch 提交被拒为 HTTP 400 | ✅ 一致（语义细节见下） |
+
+**mismatch 语义细节**：`bind-result.mismatch=true` 判定的是「绑定账号 ≠ 下单 `data.game_account`（预期账号）」（delivery.go:227-233）；`submit` 的拒绝条件是「绑定账号 ≠ **请求体提交的** game_account」（delivery.go:354-357）。正常流程提交预期账号时两者等价；若页面让用户提交的是绑定账号本身，则 mismatch=true 时也能提交通过 —— 对账/风控时留意。
+
+### 14.2 order_site 落地要点
+
+- **client_order_no 用 `task_no`**（`utils/random.ts` `randomId('DT', 6)` → `DT` + 12 hex，≤64 字符满足 affiliate_dash 限制）。order_site 自身无 client_order_no 字段，本地下单幂等由 `orders UNIQUE(provider, platform, shop_id, platform_order_id)` + `listTasks(order.id)` 已建不重建承担；affiliate_dash 侧幂等由 `client_order_no=task_no` 承担，preparePaidTask 失败重试可安全重放同一 task_no。
+- **preparePaidTask 同步拿到 order_no**（201 响应即含），写入 `context_json.affiliateDash.orderNo`；无需等回调。失败必须降级 `MANUAL_REVIEW` + `deps.notifyTaskAutoManualReview`（范式：kuaishou-feifei-executor.ts:36-51）。
+- **状态迁移路径**：见 §8 注 —— 领取页打开 `link_generated → claimed`，绑定 `→ waiting_binding`，submit 成功/回调 delivering `→ redeeming`，delivered `→ redeemed`（+核销），ship_failed `→ retry_pending`，cancelled `→ manual_review → closed`。
+- **回调幂等**：affiliate_dash 投递带 `X-Event-ID`，order_site 现无独立去重表 —— 建议 migration `013_affiliate_dash.sql` 新建 `webhook_events(event_id UNIQUE)` 去重表；事件处理用**状态合并式更新**（仿 `syncKuaishouFeifeiTaskStatus`，重复通知可重入）。接收方注意 `app.ts:31-38` 的 `express.json` 已保存 `req.rawBody`（验签必需），挂载回调路由时确认 rawBody 可用。
+- **核销联动**：`delivered` 回调 → 复用 `consumeKuaishouIndustryVouchersForTask`（`platforms/kuaishou-industry/voucher-service.ts:143`），成功 → `redeemed/completed`，失败 → `manual_review`。
+- **领取页分发**：`flowType` 扩展 `'affiliate_dash'`；`buildClaimDetailPayload`（`services/claim/kuaishou-cloud-claim-context.ts:89-92`）按 executor_key 增加分支，返回 affiliate_dash 专用 payload（商品/预期账号/当前状态/二维码相关）；前端 `ClaimPage.tsx:337-373` 增加渲染分支。

+| 16 | `services/admin/write/` | admin 手动重试/转人工按 executor 分发分支 |
+
+**前端（6 项）**：
+
+| # | 文件 | 改动 |
+|---|------|------|
+| 17 | `types/claim.ts` | `ClaimAffiliateDashFlowInfo` + flowType 扩展 |
+| 18 | `pages/claim/ClaimPage.tsx` + `claim-snapshot.ts` | `isAffiliateDashFlow` 判定与渲染分支 |

+| 21 | `pages/admin/AdminTasksPage.tsx` 等 | executor label/color 显示 |
+| 22 | `domain/task-status.ts` | 如需新增状态/转移同步（按 §8 注已有路径则无需） |
+
+### 14.4 剩余风险与待确认决策点
+
+| 项 | 说明 |
+| --- | --- |
+| 自建页 vs delivery_url 兜底 | 方案 B 以自建页为主，`delivery-link` 作降级跳转；需确认前端是否允许 iframe 内嵌 affiliate_dash H5（扫码场景无碍，跳转场景有跨域限制） |
+| 91 拆单 | 一个 91 单拆多 unit → 每 task 独立 `client_order_no`（=task_no），互不影响 |
+| 对账任务 | 回调为主 + 可选定时 `GET /orders/{order_no}` 对账（回调丢失兜底） |
+| admin 手动重试 | ship_failed / manual_review 的手动「重新 submit」入口按 executor 分发（文件清单 #16） |
+| 回调订阅确认 | 阶段 0 配置回调时确认 affiliate_dash 后台事件订阅粒度（order.created 是否必须订阅，或仅 shipping.updated 即可） |
+
+---
+
+## 15. 阶段 1 落地记录（v2.1 · 已完成）
+
+产出文件（`apps/backend/src/`）：
+
+| 文件 | 内容 |
+| --- | --- |
+| `services/platforms/affiliate-dash/config.ts` | `get/assertAffiliateDashConfig`（runtime + saved 合并）；常量 `AFFILIATE_DASH_EXECUTOR_KEY='affiliate_dash'`、`AFFILIATE_DASH_WEBHOOK_PATH='/api/v1/open/affiliate-dash'` |
+| `services/platforms/affiliate-dash/source-config-service.ts` | saved config 读写（`APP_CONFIG_KEYS.affiliateDash`，密钥存 DB 不进 git；含 `skuMapping` 归一） |
+| `services/platforms/affiliate-dash/sign.ts` | `buildClientSign`（§3.1，参数名 `app_key=`）+ `buildCallbackSign`/`verifyCallbackSign`（§3.2，`timingSafeEqual`）+ `createClientSignHeaders` |
+| `services/platforms/affiliate-dash/http-client.ts` | `affiliateDashRequest`（GET/POST、四头自动签名、AbortController 超时 502/504、错误归一、`logExternalHttpPacket` 全链路日志） |
+| `services/platforms/affiliate-dash/verify-callback.ts` | `verifyAffiliateDashCallback`（时间容差 ±300s → 验签 → 事件解析；X-Event-ID 幂等留待阶段 5） |
+| `services/platforms/affiliate-dash/order-service.ts` | 建单/查询/delivery-link/delivery/bind/bind-result/submit/wallet 全端点 + 字段映射 |
+| `services/platforms/affiliate-dash/product-service.ts` | `listAffiliateDashProducts` + `listAllAffiliateDashProducts`（翻页拉全） |
+| 配置接入 | `runtime-config.ts`、`defaults.ts`、`env-overrides.ts`（`AFFILIATE_DASH_*`）、`app-config-keys.ts` |
+| 测试 | `sign.test.ts`（黄金向量）、`verify-callback.test.ts`（通过/篡改/超容差/缺头）、`http-client.test.ts`；12/12 通过，全量 211 通过，`tsc --noEmit` 通过 |
+
+**真实联调验收**：`listAffiliateDashProducts` 直连线上 `https://skin.khhao.com` → total=33 商品，字段映射正确，签名链路与 affiliate_dash `BuildOpenV1Sign` 一致。
+
+**联调中发现并修复**：签名 `path` 必须为**纯路径**（不含 query string）；首次实现把 `/products?page=1&size=5` 整串参与签名导致线上 401「签名校验失败」，已改为 `URL.pathname` 参与签名（§3.1 表头 `path=<仅路径>` 属实）。
