1. Read related source files and tests
2. Write implementation following existing patterns
3. Add comprehensive tests
4. Run `mvn formatter:format license:format test`
5. Update JavaDoc for changed/new classes

**Principles:**
- Avoid over-engineering - keep solutions simple
- Only expose necessary public APIs
- Validate parameters with `Objects.requireNonNull()`
- Provide detailed error messages with context

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit5:5.3.0")
```

Annotate fields in test classes with `@StartStop`. The server will be started and shut down
automatically.

```
class MyTest {

  @StartStop
  public final MockWebServer server = new MockWebServer();

  @Test
  void test() {
