+# 商业化 P0 实现计划（客户端）· slogan-app
+
+> **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:** 会员中心（套餐展示 → 下单 → 系统浏览器支付 → 轮询确认）+ 广告激励入口（Mock 激励视频 → 领取加次/体验会员），后端未配置时接口报错自动隐藏充值入口。
+
+**Architecture:** /commercial 页重构为会员中心（home 第 4 Tab 与路由都指向它）。新增 `lib/core/ads/`（AdsService 抽象 + Mock 实现，P1 换穿山甲）、`lib/features/member/`（provider + 会员中心页 + 支付页）。支付用 `url_launcher` 打开系统浏览器，`/pay` 页 2s 轮询订单状态（60s 上限），成功后刷新会员状态。iOS 端隐藏充值入口（App Store 政策），保留广告激励。
+
+**Tech Stack:** Flutter 3.44 / Riverpod 3 / go_router 17 / dio 5 / url_launcher ^6.3.0
+
+**关联 spec:** `docs/superpowers/specs/2026-07-31-commerce-monetization-design.md` 支柱 A/B 客户端部分。
+
+**验证方式（沿用 MVP 惯例）：** `dart analyze`（中文路径下 flutter analyze 崩溃）、`flutter test`、`flutter build web --release` 全量编译、mock 后端冒烟。

+### Task 1: url_launcher 依赖 + 广告抽象 + 权益文案纯函数（TDD）
+
+**Files:**
+- Modify: `pubspec.yaml`
+- Create: `lib/core/ads/ads_service.dart`
+- Test: `test/features/member/benefits_test.dart`
+
+- [ ] **Step 1: 写失败测试**（权益 key → 中文文案；benefitTexts 尚未存在）
+
+`test/features/member/benefits_test.dart`:
+```dart
+import 'package:flutter_test/flutter_test.dart';
+import 'package:slogan_app/features/member/member_provider.dart';
+
+void main() {
+  test('benefitTexts 映射已知权益文案，未知 key 原样保留', () {
+    final info = MemberInfo(
+      isVip: true,
+      expireAt: '2026-08-30 12:00:00',
+      planName: '月卡',
+      benefits: const ['effect_unlimited', 'unknown_key'],
+    );
+    expect(benefitTexts(info), ['无限效果图', 'unknown_key']);
+  });
+
+  test('benefitTexts 空权益返回空列表', () {

+      benefits: const [],
+    );
+    expect(benefitTexts(info), isEmpty);
+  });
+}
+```
+
+- [ ] **Step 2: 运行确认失败**
+
+Run: `dart analyze lib test 2>&1 | head -5`  Expected: 报 `member_provider.dart` 不存在 / import 失败
+
+- [ ] **Step 3: pubspec 加 url_launcher**
+
+```yaml
+  url_launcher: ^6.3.0
+```
+
+- [ ] **Step 4: 广告抽象 `lib/core/ads/ads_service.dart`**
+
+```dart
+import 'package:flutter_riverpod/flutter_riverpod.dart';
+
+/// 广告服务抽象：P0 用 Mock（保证业务链路可开发可测），P1 换穿山甲 SDK
+abstract class AdsService {
+  bool get enabled;

+}
+
+/// 本地模拟激励视频（约 1 秒"播放"后返回完整观看）
+class MockAdsService implements AdsService {
+  @override
+  bool get enabled => true;
+
+  @override
+  Future<bool> showRewarded() async {

+
+final adsServiceProvider = Provider<AdsService>((ref) {
+  // P1：AppConfig.pangleAppId 非空时替换为 PangleAdsService（穿山甲 SDK 实现）
+  return MockAdsService();
+});
+```
+
+- [ ] **Step 5: 提交**

+> 注意：`_openPlans` 里 `plans` 变量名与 `memberPlanProvider` 无关；`showModalBottomSheet` 返回选中的套餐。依赖 `AppConfig` 在 import 中（本页未用到可删，`apiClientProvider` 来自 `api_client.dart`，StoreNotifier 里用到——需 import `../../core/network/api_client.dart`）。
+
+- [ ] **Step 2: 删除旧页并切换入口**
+
+```bash
+rm lib/features/commercial/commercial_page.dart
+```
+
+`home_page.dart` 修改：import 换 `../member/member_center_page.dart`，第 4 Tab 用 `MemberCenterPage()`，标题与 label 改为「会员中心」：
+
+```dart
+import '../member/member_center_page.dart';
+// ...
+static const _titles = ['我的形象', '我的衣橱', '穿搭方案', '会员中心'];
+// ...
+          MemberCenterPage(),

+              selectedIcon: Icon(Icons.store),
+              label: '会员'),
+```
+
+- [ ] **Step 3: main.dart /commercial 路由指向新页**
+
+`lib/main.dart`：`import '../features/member/member_center_page.dart';`，第 78-82 行 `/commercial` 的 builder 改为 `MemberCenterPage()`。
+
+- [ ] **Step 4: 静态检查**
+
+Run: `dart analyze lib 2>&1 | tail -5`  Expected: 无 error（可能提示 unused import `app_config.dart`，删掉即可）
+
+- [ ] **Step 5: 提交**
+
+```bash
+git add lib/features/member/member_center_page.dart lib/features/home/home_page.dart lib/main.dart
+git add -u lib/features/commercial
+git commit -m "feat: 会员中心页（会员卡/套餐弹层/广告激励/合作门店）"
