-**Branch**: `main` | **Date**: 2026-01-26 | **Spec**: `docs/staging_smoke_test.md`
-**Input**: 全覆盖冒烟测试需要补齐 seed 数据。
+**Branch**: `main` | **Date**: 2026-01-26 | **Spec**: `docs/seed_verification.md`
+**Input**: 将验证流程转为纯页面自动化测试（Playwright）。
 
 **Note**: 本计划遵循 `docs/templates/plan-template.md`。
 
 ## Summary
 
-扩展 seed 数据覆盖冒烟测试未覆盖项：上传素材、交互记录、创作者流程完成态、财务账本/异常、退款/对账样例，并复核冒烟清单是否仍有缺口。
+新增一份“纯页面自动化验证”文档，包含服务启动步骤（backend/portal/superadmin）和 Playwright 操作清单，确保 AI 能在无 API 调用前提下完成冒烟验证。
 
 ## Technical Context
 
-**Language/Version**: Go 1.22
-**Primary Dependencies**: Fiber, GORM-Gen
-**Storage**: PostgreSQL + Redis
-**Testing**: `go test ./...`
-**Target Platform**: staging
+**Language/Version**: JS (Playwright) + Go 1.22 + Vite
+**Primary Dependencies**: Playwright, Vite dev server
+**Storage**: PostgreSQL (seed 数据)
+**Testing**: 页面自动化 (browser-driven)
+**Target Platform**: Local + staging
 **Project Type**: Web application
 **Performance Goals**: N/A
-**Constraints**: 不改生成文件；seed 逻辑仅在 `backend/app/commands/seed/seed.go`。
-**Scale/Scope**: 覆盖冒烟清单全场景
+**Constraints**: 仅写文档，不修改业务代码
+**Scale/Scope**: 覆盖 portal + superadmin 冒烟场景

 ## Plan Phases
 
-### Phase 1: 缺口确认
-- 对照冒烟清单明确缺失数据类型。
+### Phase 1: 启动流程梳理
+- 明确 backend/portal/superadmin 本地启动方式与代理关系。
 
-### Phase 2: Seed 扩展
-- 添加交互记录、退款/对账样例、财务账本、异常/风控数据、创作者完成态、上传素材。
+### Phase 2: 自动化场景清单
+- 按 portal/superadmin 视图输出可自动化步骤与断言。
 
-### Phase 3: 复核
-- 深度复查冒烟清单覆盖率并记录残余缺口。
+### Phase 3: 输出验证文档
+- 更新 `docs/seed_verification.md` 为“纯页面自动化”版本。

 ## Acceptance Criteria
 
-- seed 后冒烟清单所有场景具备至少一条数据支撑。
-- 记录残余缺口（如必须手动步骤）。
+- 文档包含完整启动流程与端口说明。
+- 文档包含可直接执行的页面自动化步骤。
+- 不涉及 API 级验证说明。
 
 ## Risks
 
-- staging 数据冲突导致重复创建失败。
+- 登录依赖 OTP/浏览器控制台获取。

+# Seed Verification Guide (Staging)
+
+## Service Startup (Local)
+
+- Backend: `go run ./backend/main.go serve` (default `http://localhost:8080`).
+- Portal frontend: `npm -C frontend/portal install` then `npm -C frontend/portal run dev` (default `http://localhost:5174`).
+- Superadmin frontend: `npm -C frontend/superadmin install` then `npm -C frontend/superadmin run dev` (default `http://localhost:5173`).
+- Portal dev server proxies `/v1` to `http://localhost:8080` (`frontend/portal/vite.config.js`).
+- Superadmin dev server proxies `/super/v1` and `/v1` to `http://localhost:8080` (`frontend/superadmin/vite.config.mjs`).
+
+## Run Seed
+
+- Execute `go run ./backend/main.go seed`.
+- Ensure no panics; capture console output for troubleshooting.
+
+## Data Validation (DB/Logs)
+
+- Users: verify `creator`, `test`, `superadmin`, `negative` exist in `users.username`.
+- Tenant: read `tenants.code` to obtain `tenantCode` (DB query or admin UI).
+- Memberships: `tenant_users` includes `creator` as `tenant_admin`, `test` as `member`.
+- Orders: `orders` has `content_purchase` + `withdrawal`, plus flagged/reconciled records.
+- Ledger: `tenant_ledgers` has at least one row.
+- Templates: `notification_templates` contains order/audit/interaction types.
+
+## Portal Smoke (Use tenantCode)
+
+- Tenant code: query DB, then open `http://localhost:5174/t/:tenantCode`.
+- Login: OTP is fixed to `1234` (see `backend/app/services/user.go`).
+- Home: `/t/:tenantCode` lists content.
+- Detail: open any content detail; cover and main asset render.
+- Login: sign in as `test` (phone `13800138000`, OTP `1234`) and open `/t/:tenantCode/me`.
+- Orders & Library: `/t/:tenantCode/me/orders` and `/t/:tenantCode/me/library` show data.
+- Likes/Favorites: content detail shows prefilled like/favorite; toggle to confirm.
+- Notifications: `/t/:tenantCode/me/notifications` shows unread items.
+
+## Superadmin Smoke
+
+- Open `http://localhost:5173/super/auth/login`.
+- Login: `superadmin` / `superadmin123`.
+- Users: list includes `negative`; balance anomaly list returns result.
+- Orders: list includes flagged/reconciled and refund orders.
+- Withdrawals: list contains `created`/`paid`/`failed` statuses.
+- Finance: ledger list has data; order anomaly list returns missing paid/refund items.
+- Content/Reports: content list is populated; report list has pending item.
+- Templates: order/audit/interaction templates present.
+- System Configs: `site_name` and `support_email` present.
+
+## Manual-Only Coverage
+
+- Upload flow (init/part/complete) requires real storage integration; seed only preloads assets.
