### Architecture Overview

The library follows a layered architecture:

- **Context Layer**: `CIFSContext` interface provides the main entry point
- **Resource Layer**: `SmbResource` interface represents SMB network resources  
- **Protocol Layers**: Separate SMB1 (`jcifs.internal.smb1/`) and SMB2/3 (`jcifs.internal.smb2/`) implementations
- **Authentication**: NTLM, Kerberos, SPNEGO unified subsystem
