Coming back to the previous code example, **FastAPI** will:

* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
    * If it is not, the client will see a useful, clear error.

## 🏗️ Architecture & Design Patterns

### Core Design Principles
CoreLib follows a **utility-class pattern** where most functionality is exposed through static methods:

- **Assertion-based validation** - All methods validate inputs using `AssertionUtil.assertArgumentNotNull()` and `AssertionUtil.assertArgumentNotEmpty()`

        }
    }
    
    public void validateNotification(WitnessNotification notification) throws SecurityException {
        // Validate notification authenticity
        if (!isValidNotificationSource(notification)) {
            throw new SecurityException("Invalid witness notification source");
        }
    }
    

        } finally {
            Thread.currentThread().setContextClassLoader(oldCL);
            System.setProperties(oldProps);
        }
    }

    protected int doInvoke(C context) throws Exception {
        validate(context);
        pushCoreProperties(context);
        pushUserProperties(context);
        setupGuiceClassLoading(context);
        configureLogging(context);
        createTerminal(context);
