-# ADR-007 Error Handling Strategy
-
-## CRITICAL RULES
-
-- **ALWAYS** use layered error classification (Validation, Business, System)
-- **NEVER** expose technical details to end users
-- **ALWAYS** provide user-friendly error messages with recovery guidance
-- **ALWAYS** log technical details for debugging
-- **NEVER** use generic error messages without context
-
-## Error Classification
-
-| Error Type | Description | User Message | Technical Log |
-|------------|-------------|--------------|---------------|
-| **Validation** | Input validation failures | Clear field-level errors | Full validation details |
-| **Business** | Business rule violations | Actionable guidance | Business context + user ID |
-| **System** | Infrastructure failures | Generic "try again" | Full stack trace + metrics |
-
-## Backend Pattern (NestJS)
-
-```typescript
-// Custom Exception Hierarchy
-export class BusinessException extends HttpException {
-  constructor(
-    message: string,
-    userMessage: string,
-    recoveryAction?: string,
-    errorCode?: string
-  ) {
-    super({ message, userMessage, recoveryAction, errorCode }, 400);
-  }
-}
-
-// Global Exception Filter
-@Catch()
-export class GlobalExceptionFilter implements ExceptionFilter {
-  catch(exception: unknown, host: ArgumentsHost) {
-    // Classify error and provide appropriate response
-    // Log technical details
-    // Return user-friendly message
-  }
-}
-```
-
-## Frontend Pattern (Next.js)
-
-```typescript
-// Error Display Component
-const ErrorDisplay = ({ error, onRetry }) => {
-  const userMessage = error.userMessage || 'เกิดข้อผิดพลาด';
-  const recoveryAction = error.recoveryAction;
-
-  return (
-    <div>
-      <p>{userMessage}</p>
-      {recoveryAction && <p>{recoveryAction}</p>}
-      {onRetry && <button onClick={onRetry}>ลองใหม่</button>}
-    </div>
-  );
-};
-```
-
-## Required Implementation
-
-- [ ] Global Exception Filter with layered classification
-- [ ] Custom exception hierarchy (Validation, Business, System)
-- [ ] Standardized error response DTOs
-- [ ] Frontend error display components
-- [ ] Error recovery mechanisms where applicable
