## 🏗️ 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()`

- Kubectl: fixed a bug where `kubectl convert` did not pick the right API version ([#112700](https://github.com/kubernetes/kubernetes/pull/112700), [@SataQiu](https://github.com/SataQiu))
- Kubelet now cleans up the Node's cloud node IP annotation correctly if you
  stop using `--node-ip`. (In particular, this fixes the problem where people who
  were unnecessarily using `--node-ip` with an external cloud provider in 1.23,

 * <ul>
 *   <li>Can't be passed directly to methods that expect {@code Iterable}, {@code Collection}, or
 *       {@code List} (though the most common utilities do have replacements here, and there is a
 *       lazy {@link #asList} view).
 * </ul>
