## Task: Create UserPresence Entity

### Test Date
2026-02-24

### Requirements Analysis
- ✅ UserId (primary key) - Guid type required
- ✅ Status (enum: Online, Offline, Away) - Need to create UserStatus enum
- ✅ LastSeenAt (DateTime) - DateTime type required
- ✅ ConnectionId (for SignalR) - String type required

### Existing Codebase Analysis
- ✅ Message entity exists at `Chat.Domain/Entities/Message.cs`
- ✅ Conversation entity exists at `Chat.Domain/Entities/Conversation.cs`
- ✅ MessageStatus enum exists at `Chat.Domain/Enums/MessageStatus.cs`
- ✅ Context exists at `Chat.Domain/Context.cs` with Message and Conversation DbSets

### Code Pattern Analysis
- Entities use XML documentation comments
- Properties follow C# naming conventions (PascalCase)
- Guid types for primary keys
- DateTime for timestamps
- Navigation properties commented out for future use
- Context includes entity configuration in OnModelCreating

### Test Cases Identified
1. Create UserStatus enum in Chat.Domain/Enums/
2. Create UserPresence entity in Chat.Domain/Entities/
3. Update Context.cs with UserPresence DbSet and configuration
4. Verify the entity follows existing patterns
5. Verify all required properties are present

### Conclusion
**Status: SUCCESS**

All requirements are clear and the existing codebase provides a clear pattern to follow. Ready to proceed to Dev_Agent.
