+# Error Handling and Edge Case Strategy
+
+## Personality Data Manager Error Scenarios
+
+### Profile Validation Errors
+1. `INVALID_PROFILE_SCHEMA`: Profile does not match required structure
+2. `DUPLICATE_PROFILE_ID`: Attempt to create profile with existing ID
+3. `VERSION_CONFLICT`: Outdated profile version
+
+### Profile Management Errors
+1. `PROFILE_NOT_FOUND`: Requested profile does not exist
+2. `INSUFFICIENT_PERMISSIONS`: Unauthorized profile modification
+3. `STORAGE_LIMIT_EXCEEDED`: Maximum number of profiles reached
+
+## Conversation Orchestrator Error Scenarios
+
+### Session Management Errors
+1. `SESSION_INITIALIZATION_FAILED`: Unable to create conversation session
+2. `MAX_SESSIONS_EXCEEDED`: Limit on concurrent sessions reached
+3. `INVALID_SESSION_ID`: Attempted operation on non-existent session
+
+### Message Processing Errors
+1. `AGENT_UNAVAILABLE`: Selected agent cannot process message
+2. `MESSAGE_ROUTING_FAILED`: Unable to route message between agents
+3. `CONVERSATION_TIMEOUT`: Session exceeded maximum duration
+
+## General Error Handling Principles
+- Provide clear, actionable error messages
+- Include error codes for programmatic handling
+- Log comprehensive error details for debugging
+- Implement graceful degradation strategies
+
+## Recommended Error Response Structure
+```typescript
+interface ErrorResponse {
+  code: string;
+  message: string;
+  details?: any;
+  timestamp: number;
+  requestId?: string;
+}
+```
+
+## Logging and Monitoring
+- Centralized error logging
+- Error severity classification
+- Performance impact tracking
+- Automated alert mechanisms
