When a new feature is created and its first batch of checklist is generated.
* **Generate Checklist**
When user requests to generate Checklist
* **Update with changes requests**\
All user requests to adjust, add, remove, merge, or split checklist via the "Update with changes" workflow.
* **Test cases generation**\
Each time test cases are generated (all at once, by category/sub-category, or individually).
* **Continue generating test cases**\
Events when you use the "Continue" button to finish generating pending test cases after an update.
* **Update test case requests**\
Any time you submit a request to update an individual test case.

Each entry in the timeline includes a timestamp, a summary of the action, and often a “View” link to see the version as it was at that point.
