+# Task 5 Implementation Verification
+
+## Task: Backend - Implement PUT endpoint for updating custom status
+
+**Status:** ✅ COMPLETED
+
+## Requirements Verification
+
+### Requirement 2.1: Support updating name
+✅ **IMPLEMENTED**
+- Location: `backend/routers/projects.py` lines 1565-1593
+- The endpoint accepts an optional `name` field in the request body
+- Updates the status name when provided
+- Validates name uniqueness before updating
+
+### Requirement 2.2: Support updating color
+✅ **IMPLEMENTED**
+- Location: `backend/routers/projects.py` lines 1595-1597
+- The endpoint accepts an optional `color` field in the request body
+- Updates the status color when provided
+- Color format validation is handled by the `CustomTaskStatusUpdate` schema
+
+### Requirement 2.3: Support updating is_default flag
+✅ **IMPLEMENTED**
+- Location: `backend/routers/projects.py` lines 1599-1611
+- The endpoint accepts an optional `is_default` field in the request body
+- Updates the default status flag when provided
+- Handles both setting and unsetting the default flag
+
+### Requirement 5.2: If setting as default, unset other default statuses
+✅ **IMPLEMENTED**
+- Location: `backend/routers/projects.py` lines 1601-1607
+- When `is_default` is set to `True`, the endpoint automatically unsets all other default statuses
+- Ensures only one default status exists at a time
+- This is done by iterating through all custom statuses and setting their `is_default` to `False` before setting the current status as default
+
+### Additional Requirement: Validate name uniqueness if name is changed
+✅ **IMPLEMENTED**
+- Location: `backend/routers/projects.py` lines 1565-1593
+- Validates that the new name doesn't conflict with:
+  - Other custom statuses in the same project
+  - System status names
+- Returns 409 Conflict error if name already exists
+
+### Additional Requirement: Use flag_modified for JSON column updates
+✅ **IMPLEMENTED**
+- Location: `backend/routers/projects.py` line 1617
+- Uses `flag_modified(db_project, 'custom_task_statuses')` to ensure SQLAlchemy detects changes to the JSON column
+- This is critical for proper database persistence of JSON column updates
+
+## Implementation Details
+
+### Endpoint Signature
+```python
+@router.put("/{project_id}/task-statuses/{status_id}")
+async def update_custom_task_status(
+    project_id: int,
+    status_id: str,
+    status_update: dict,
+    db: Session = Depends(get_db),
+    current_user: User = Depends(require_coordinator_or_admin)
+)
+```
+
+### Request Body Schema
+Uses `CustomTaskStatusUpdate` from `backend/schemas/custom_task_status.py`:
+```python
+{
+    "name": "string (optional)",        # 1-50 characters
+    "color": "string (optional)",       # Hex color code (e.g., #FF5733)
+    "is_default": "boolean (optional)"  # Set as default status
+}
+```
+
+### Response Schema
+Returns `CustomTaskStatusResponse`:
+```python
+{
+    "message": "string",
+    "status": {
+        "id": "string",
+        "name": "string",
+        "color": "string",
+        "order": "integer",
+        "is_default": "boolean"
+    },
+    "all_statuses": {
+        "statuses": [...],           # All custom statuses
+        "system_statuses": [...],    # System statuses
+        "default_status_id": "string"
+    }
+}
+```
+
+## Key Features
+
+1. **Partial Updates**: All fields are optional, allowing partial updates
+2. **Name Uniqueness Validation**: Prevents duplicate names within a project
+3. **System Status Protection**: Prevents using system status names
+4. **Default Status Management**: Automatically manages default status uniqueness
+5. **JSON Column Handling**: Properly uses `flag_modified` for database persistence
+6. **Authorization**: Requires coordinator or admin role
+7. **Comprehensive Error Handling**: Returns appropriate HTTP status codes
+
+## Error Responses
+
+- **404 Not Found**: Project or status doesn't exist
+- **409 Conflict**: Name already exists or conflicts with system status
+- **403 Forbidden**: User lacks coordinator/admin permissions
+- **422 Unprocessable Entity**: Invalid request body format
+
+## Testing
+
+Comprehensive test suite exists at `backend/test_update_custom_task_status.py` covering:
+- ✅ Status name update
+- ✅ Status color update
+- ✅ Both name and color update
+- ✅ Name uniqueness validation
+- ✅ System status name conflict detection
+- ✅ Setting status as default
+- ✅ Changing default status (unsets previous default)
+- ✅ Unsetting default status
+- ✅ Non-existent status handling
+- ✅ JSON column persistence verification
+
+## Documentation
+
+Complete documentation available at:
+- `backend/docs/custom-task-status-update-endpoint.md`
+
+## Conclusion
+
+Task 5 is **FULLY IMPLEMENTED** and meets all specified requirements:
+- ✅ PUT endpoint added to `backend/routers/projects.py`
+- ✅ Supports updating name, color, and is_default flag
+- ✅ Validates name uniqueness when name is changed
+- ✅ Unsets other default statuses when setting a new default
+- ✅ Uses `flag_modified` for JSON column updates
+- ✅ Comprehensive test coverage
+- ✅ Complete documentation
+
+The implementation is production-ready and follows best practices for FastAPI development.
