## 🏗️ 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()`

    @DisplayName("write(boolean/byte): writes single byte")
    void write_oneByteVariants() throws Exception {
        SmbRandomAccessFile raf = spy(newInstance("rw", false, true, false));
        // Intercept the 3-arg write to validate len
        doNothing().when(raf).write(any(byte[].class), anyInt(), anyInt());
        raf.writeBoolean(true);
        raf.writeByte(0x7F);
        ArgumentCaptor<Integer> lenCap = ArgumentCaptor.forClass(Integer.class);
