### Architecture Overview

The library follows a layered architecture:

        KerberosKey kdcKey = new KerberosKey(null, keyBytes, PacSignature.HMAC_SHA1_96_AES256, 1);
        keys.put(PacSignature.ETYPE_AES256_CTS_HMAC_SHA1_96, kdcKey);

        // Mock Pac construction to bypass complex validation
        try (MockedConstruction<Pac> pacMock = Mockito.mockConstruction(Pac.class, (mock, context) -> {
            // Setup mock behavior
            PacLogonInfo mockLogonInfo = Mockito.mock(PacLogonInfo.class);

## Do not use Pydantic RootModels

Do not use Pydantic `RootModel`, instead use regular type annotations with `Annotated` and Pydantic validation utilities.

For example, for a list with validations you could do:

```python
from typing import Annotated

from fastapi import Body, FastAPI
from pydantic import Field

app = FastAPI()


@app.post("/items/")
