### 2.4 Business Logic Pattern Evidence

#### 2.4.1 Dual Architecture Pattern
**Evidence from CLAUDE.md**:
```
#### WPF UI Architecture (3-layer pattern | ILogic Interface Pattern)
All data operations in the UI must use the ILogic interface accessed through ClassContainer:
- WPF UI modules use a 3-part data access pattern:
    - I{Module}Logic interface - Defines the contract
    - BL{Module}Logic (NHibernate/SQL Server) - Direct database access
    - WS{Module}Logic (REST API) - Web service access via REST API
- Access via ClassContainer.Instance.WithInstance((ILogic logic) => ...).ThrowIfError();
```

**Code Pattern Evidence**:
```csharp
// Example data access pattern
var result = await ClassContainer
    .Instance
    .WithInstance((IAccountContractsLogic logic) => logic.GetAccountContracts(filter))
    .ThrowIfError();
```

**Architecture Stakeholder Impact**:
- **Internal Users**: Direct database access via WPF client for performance
- **External Users**: Web service access for security and scalability
- **IT Administrators**: Dual deployment and management complexity
- **Integration Partners**: RESTful API access for external systems

**Stakeholder Requirements Derived**:
- StR-079: Windows OS compatibility (WPF client)
- StR-080: Web browser compatibility (web services)
- StR-070: System availability requirements
- StR-065: Performance requirements
