Add environment variable documentation and error handling
The OPENAI_API_KEY environment variable needs attention in two areas:
- No documentation found in any README files or .env.example
- Missing error handling for undefined API key (see llm-server/src/model/openai-model-provider.ts for reference implementation)

15-19: Verify OPENAI_API_KEY environment variableThe OpenAI client is initialized with OPENAI_API_KEY from environment variables. Ensure:
- This variable is properly documented in README
- There's proper error handling if the key is missing

17-17: Verify dependencies after HttpModule and ModelProvider removalThe removal of HttpModule and ModelProvider could impact dependent modules. Please ensure:
- Any HTTP functionality previously using HttpModule has been properly migrated
- No other modules are still trying to import ModelProvider from ChatModule
Also applies to: 29-29
✅ Verification successful
Removal of HttpModule and ModelProvider is safe ✅
The changes are verified to be safe:
- No modules import ModelProvider from ChatModule
- ChatService has been refactored to use only TypeORM repositories
- No HTTP client usage found in the codebase that would require HttpModule

57-103: Remove commented out MessageGuard code.Instead of keeping the commented-out implementation, we should remove it entirely since it's no longer needed. If needed later, it can be retrieved from version control history.
-// @Injectable() -// export class MessageGuard implements CanActivate { - // ... (remove all commented code) -// }Additionally, please verify that message-level authorization is properly handled elsewhere in the codebase.
✅ Verification successful
Removal of MessageGuard is correct - message authorization is handled at chat level
The codebase implements a hierarchical security model where:
- All chat operations are protected with JWT authentication
- Messages are always accessed within their parent chat context
- Chat-level authorization implicitly protects the contained messages

Update GraphQL schema and test file for Role/MessageRole consistency
The Role enum in the GraphQL schema needs to be updated to match the backend's MessageRole enum. Found inconsistencies in:

💡 Codebase verification
Update test file to use MessageRole.Assistant
The change from Model to Assistant is correct according to the schema. However, the isolation test file backend/src/chat/__tests__/chat-isolation.spec.ts still uses the old MessageRole.Model and needs to be updated to use MessageRole.Assistant.
🔗 Analysis chain
Verify the impact of changing MessageRole.
The change from MessageRole.Model to MessageRole.Assistant aligns with the schema updates. However, we should verify the impact on existing messages in the database.
