```
## Security Architecture
### Authentication
- **Method**: Email magic links (passwordless)
- **Sessions**: JWT stored in HTTP-only cookies
- **Provider**: NextAuth.js with custom email provider
### Authorization (RBAC)
- **Enforcement**: tRPC middleware checks role before procedure
- **Granularity**: Role + resource-level (jury sees only assigned projects)
- **Storage**: User.role field in database
### Data Security
- **File Access**: Pre-signed URLs with short TTL (15 min)
- **SQL Injection**: Prevented by Prisma parameterized queries
- **XSS**: React's built-in escaping + CSP headers
- **CSRF**: NextAuth.js built-in protection
### Audit Trail
- **Coverage**: All admin actions, all state changes
- **Immutability**: Append-only audit_logs table
- **Fields**: user, action, entity, details, timestamp, IP
## Scalability Considerations
### Current Design (Phase 1)
- Single PostgreSQL instance (sufficient for ~200 concurrent users)
- Single Next.js instance behind Nginx
- MinIO for file storage (horizontally scalable)
### Future Scale Path
1. **Database**: Read replicas for dashboards, connection pooling (PgBouncer)
2. **Application**: Multiple Next.js instances behind load balancer
3. **Caching**: Redis for session storage and query caching
4. **CDN**: Static assets via CDN
5. **Background Jobs**: BullMQ for email queues, exports
## Smart Assignment System
The platform includes two assignment modes:
### 1. AI-Powered Assignment (GPT)
- Analyzes juror expertise and project tags
- Optimizes for balanced workload
- Respects organizational conflicts
- **Privacy**: All data is anonymized before sending to GPT
- Names → `JUROR_A`, `JUROR_B`
- Projects → `PROJECT_1`, `PROJECT_2`
- Organizations → `ORG_X`, `ORG_Y`
- Emails and personal details are never sent
### 2. Smart Algorithm (Rule-Based Fallback)
- Fully featured scoring algorithm
- No external API required
- Handles 200 projects × 50 jurors in < 1 second
- Deterministic results
**Scoring Formula**:
```
Score = (expertise_match × 40) + (load_balance × 25) +
(specialty_match × 20) + (diversity × 10) - (conflict × 100)
```
## Admin Settings Panel
Centralized configuration for:
- **AI Configuration**: Provider, API key, model, budget limits
- **Platform Branding**: Logo, colors, name
- **Email/SMTP**: Server, credentials, templates
- **File Storage**: MinIO endpoint, bucket, limits
- **Security**: Session duration, rate limits
- **Defaults**: Timezone, pagination, autosave interval
## User Roles (RBAC)
| Role | Permissions |
|------|------------|
| **SUPER_ADMIN** | Full system access, all programs, user management |
| **PROGRAM_ADMIN** | Manage specific programs, rounds, projects, jury |
| **JURY_MEMBER** | View assigned projects only, submit evaluations |
| **OBSERVER** | Read-only access to dashboards |
