## Context
- 问题 / 目标:P1 Complete 后缺少内部运维面;需可审计的用户/订单查询与会员授予。
- 非目标:UGC/达人/CMS/RBAC/真支付。
- 相关 Spec / ADR`.ai/product/feature-spec/ops-admin.md`;无新 ADR(栈与分层不变)。
## Architecture Change
- 是否改变分层边界:No
- 受影响层:API · Application(新 `service/admin`)· Infrastructurerepo + migration)· UI`apps/admin-h5`
## Module Changes
| Module | Layer | Change | Must NOT |
|--------|-------|--------|----------|
| `handler/admin*.go` | API | bind/auth 头/调 service | SQL;权益规则细节堆在 handler |
| `service/admin` | Application | 登录、列表、grant、审计 | 直连 gin |
| `repository/admin_repo.go` | Infrastructure | SQL | 业务解锁语义外泄 |
| `middleware/admin_auth.go` | API | 校验 admin session | 复用 DeviceAuth 冒充 |
| `apps/admin-h5` | UI | Vue3 控制台 | 裸 fetch 拼完整 URL(走 thin api → sdk 或本地 client |
## Data Flow
```text
admin-h5
→ POST /admin/auth/login → admin_accounts 校验 → 写 admin_sessions → token
→ Bearer token → AdminAuth → service/admin
→ AdminRepo / ReportRepo(memberships,orders) / ProfileRepo 摘要
→ grant → UPDATE memberships + INSERT admin_audit_logs
```
## API Changes
- 契约:`apps/api/proto/openapi.yaml` 增补 `/admin/*`
- 兼容:新增路径,不影响既有 user API
- 信封:项目既有 `{code,message,data}`
## Database Changes
- `admin_accounts` · `admin_sessions` · `admin_audit_logs`(见 ERD
- Immutable observation:审计表只追加
- Migration`000010_admin_ops.up.sql` / `.down.sql`
## Migration Plan
- RequiredYES
- 步骤:expand(建表)→ 启动 bootstrap 种子(可选)→ 无 contract
- 回滚:down migration 删三表(开发环境可接受)
## Failure Handling
- 登录失败:统一模糊文案(不暴露是否用户存在细节过度)· 审计可选记 fail
- Token 无效/过期:401
- grant:用户不存在 404plan 非法 400DB 错 500
- 幂等:grant 非严格幂等;重复授予延长 expires_at 并再记审计
## Test Plan
- Unitpassword verify · plan duration
- Integrationlogin → list users → grant → audit
- API401 without token
## Rollback Plan
- 代码回滚去掉 admin 路由注册
- down migration
- 配置去掉 bootstrap

## Backend Change Boundarymandatory
```text
Change Level: L2
Change: 新增 admin 鉴权面与运维读写 API + admin-h5
Affected:
Domain:
- AdminAccount / AdminSession / AdminAuditLog(运维身份,非终端 User
Application:
- service/adminlogin, users, orders, grant, audit
Infrastructure:
- AdminRepo · migration 000010
API:
- /api/v1/admin/*
Migration: Required
Tests:
- admin auth + grant path
Risk: Medium
```
## Architecture Regression Check
- [x] 无重复业务逻辑(会员写入复用既有 memberships 语义)
- [x] 无绕过 Service
- [x] 无 Handler 直连 DB
- [x] 无 utility dumping
- [x] 无隐藏全局状态
- [x] bootstrap 配置可追踪(config.example.yaml
- [x] 未简化既有分层
