+{
+    Task<string> UploadAsync(string containerName, string fileName, Stream content);

+
+## Key Architectural Decisions
+
+### 1. Microservices with Service Mesh
+- **Rationale**: Clean separation of concerns, independent scaling
+- **Communication**: HTTP REST + SignalR for real-time updates
+- **Service Discovery**: Docker network DNS resolution
+
+### 2. Hangfire for Background Processing
+- **Benefits**: .NET native, web dashboard, persistent queues
+- **Use Cases**: Document generation, cloud uploads, batch processing
+- **Storage**: PostgreSQL for job persistence
+
+### 3. Strategy Pattern for External Integrations
+- **Cloud Storage**: Pluggable providers (S3, Box, FTP)
+- **Help Centers**: Extensible article update system
+- **Benefits**: Easy to add new providers without core changes
+
+### 4. SignalR for Real-time Updates
+- **Use Cases**: Build status, publishing progress, job completion
+- **Frontend Integration**: React SignalR client with auto-reconnection
+
+### 5. Entity Framework with Repository Pattern
+- **Database**: Code-first migrations
+- **Testing**: In-memory provider for unit tests
+- **Performance**: Query optimization with projection
+
+## Security Considerations
+
+### Authentication & Authorization
+- JWT tokens with refresh mechanism
+- Role-based access control (Admin, User, ReadOnly)
+- Secure password hashing (bcrypt)
+
+### API Security
+- HTTPS only in production
+- CORS properly configured
+- API rate limiting
+- Input validation and sanitization
+
+### Secrets Management
+- Docker secrets for production
+- Environment variables for configuration
+- No hardcoded credentials
+
+## Deployment Strategy
+
+### Development
+- Docker Compose with hot-reload volumes
+- Shared PostgreSQL instance
+- Frontend dev server proxy to API
+
+### Production
+- Individual Docker containers
+- Nginx reverse proxy
+- PostgreSQL with persistent volumes
+- Health checks and restart policies
+
+## Questions for Next Phase
+
+1. **CC.NET Integration**: What format are the log files? XML, plain text, or proprietary?
+2. **Manuscript API**: Is there existing API documentation or will we need to reverse-engineer?
+3. **Document Templates**: Do you have existing release note templates or should we create standard ones?
+4. **Cloud Storage**: Any specific bucket/container naming conventions?
+5. **Help Center**: Do you have existing article templates or categories to work with?
