 * 1. Have identical signatures in both client and server modes
 * 2. Return identical data structures
 * 3. Handle errors consistently
 * 4. Work seamlessly regardless of connection mode

### Perfect Plug and Socket Design

The goal is to achieve 100% method parity where:
- Every client method has an exact server counterpart
- Identical method signatures and return types
- Seamless switching between client and server modes
- Shared business logic works in both environments
