Architecture Overview

The toolkit follows a layered design:

• CLI handles user input
• Inventory loader provides device data
• Executor coordinates multi-device execution
• Connector manages SSH lifecycle per device
• Logger provides centralized observability

This separation improves maintainability, testability, and extensibility.
