-## Phase 1: Infrastructure & Automation Core
+## Phase 1: Infrastructure & Automation Core [checkpoint: 7626531]
 Establish the foundation for driving the GUI via API hooks and simulation logic.
 
 - [x] Task: Extend `ApiHookClient` with methods for tab switching and listbox selection if missing. f36d539
 - [x] Task: Implement `TestUserAgent` class to manage dynamic response generation and action delays. d326242
 - [x] Task: Write Tests (Verify basic hook connectivity and simulated delays) f36d539
 - [x] Task: Implement basic 'ping-pong' interaction via hooks. bfe9ef0
