 ## 2025-11-20: Unified Ajax Error Response System
 
 **Component**: Ajax error handling
-**Impact**: Medium - Existing error handling code continues to work, but new pattern recommended
+**Impact**: Documentation clarification - unified pattern is the only implemented pattern
 
 ### Change
 
-Replaced fragmented error response helpers (`response_form_error()`, `response_auth_required()`, etc.) with unified `response_error()` function using constants for error codes. Same constant names on server and client for zero mental translation.
+Adopted unified `response_error()` function with error code constants. Same constant names on server and client for zero mental translation.
 
-### Previous Pattern
+**Note**: The fragmented helper functions (`response_form_error()`, `response_auth_required()`, etc.) shown in earlier documentation were a planned design that was superseded before implementation. Only `response_error()` exists.
 
-```php
-// Server - different functions for each error type
-return response_form_error('Validation failed', ['email' => 'Invalid']);
-return response_not_found('Project not found');
-return response_unauthorized('Permission denied');
-```
-
-```javascript
-// Client - string matching with different names
-if (error.type === 'form_error') { ... }
-if (error.type === 'not_found') { ... }
-```

-### Migration Steps
+### Documentation
 
-1. **Update server-side error responses** to use `response_error()` with constants
-2. **Update client-side error checks** to use `e.code === Ajax.ERROR_*` instead of `e.type === 'string'`
-3. **Read updated documentation**: `php artisan rsx:man ajax_error_handling`
-
-Old helpers still work but are deprecated. Framework code being updated to new pattern.
+See `php artisan rsx:man ajax_error_handling` for complete usage.
