## Analysis Summary

### Total Files Reviewed: 30+

### Key Statistics
- **Total API Routes**: 14 endpoints across 8 route files
- **Database Models**: 7 (User, Session, Account, Verification, Level, WxUser, WxUserLevelProgress)
- **Protected Pages**: 3 (levels, users, wx-users)
- **Public Pages**: 1 (login)
- **UI Components**: 15+
- **Utility Libraries**: 6 key files
- **Dependencies**: 30+ npm packages

### Code Structure Quality
- ✅ Well-organized folder structure
- ✅ Consistent naming conventions
- ✅ Type safety throughout (TypeScript)
- ✅ Error handling in all endpoints
- ✅ Session validation patterns consistent
- ✅ React Query for state management
- ✅ Component composition is clean

---

## Key Findings

### 1. Architecture
- **Framework**: Next.js 14 with App Router
- **Deployment Model**: Standalone (single binary)
- **Reverse Proxy**: Behind `/studio` basePath
- **Auth System**: Better Auth with MySQL Prisma adapter
- **Session Duration**: 7 days with 1-day update age

### 2. Database Design
- **Provider**: MySQL
- **ORM**: Prisma v6.5.0
- **Models**: 7 total (Better Auth + custom models)
- **Relationships**: One-to-many (WxUser → WxUserLevelProgress → Level)
- **Cascade Delete**: Implemented for Sessions/Accounts

### 3. API Patterns
- **Auth Check**: All routes validate session before proceeding
- **Error Handling**: Consistent error responses
- **Validation**: Input validation in all POST/PUT routes
- **Transactions**: Used for multi-step operations (user creation, reordering)
- **Pagination**: Implemented for WeChat users list

### 4. Security
- ✅ Session-based authentication
- ✅ Password hashing (bcryptjs + better-auth/crypto)
- ✅ Cookie validation (handles HTTP and HTTPS prefixes)
- ✅ Self-delete prevention in user management
- ✅ Temporary COS credentials (30-minute expiry)

### 5. Notable Gotchas
- ⚠️ BETTER_AUTH_URL must NOT contain path component
- ⚠️ basePath excluded from request.nextUrl.pathname in Next.js 14
- ⚠️ Middleware uses cookie check only (no Prisma in Edge Runtime)
- ⚠️ HTTPS adds `__Secure-` prefix to cookies
- ⚠️ apiFetch() must be used for client-side API calls

### 6. Missing Features
- ❌ No sharing/invite system
- ❌ No permission/role system
- ❌ No audit logging
- ❌ No soft deletes
- ❌ No rate limiting
- ❌ All authenticated users have full admin access
