## 🏗️ Architecture & Design Patterns

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

    assertThat(newArray).isEqualTo(new byte[] {(byte) 0, (byte) 1, (byte) 2});
    newArray[1] = (byte) 5;
    assertThat((byte) list.get(1)).isEqualTo((byte) 1);
  }

  // This test stems from a real bug found by andrewk
  public void testAsList_subList_toArray_roundTrip() {
    byte[] array = {(byte) 0, (byte) 1, (byte) 2, (byte) 3};
    List<Byte> list = Bytes.asList(array);
